It is only of interest for Digital TV + device driver writers. The header file for this API is named + demux.h and located in + drivers/media/dvb-core. + + The demux API should be implemented for each demux in the + system. It is used to select the TS source of a demux and to manage + the demux resources. When the demux client allocates a resource via + the demux API, it receives a pointer to the API of that + resource. + Each demux receives its TS input from a DVB front-end or from + memory, as set via this demux API. In a system with more than one + front-end, the API can be used to select one of the DVB front-ends + as a TS source for a demux, unless this is fixed in the HW platform. + The demux API only controls front-ends regarding to their connections + with demuxes; the APIs used to set the other front-end parameters, + such as tuning, are not defined in this document. + The functions that implement the abstract interface demux should + be defined static or module private and registered to the Demux + core for external access. It is not necessary to implement every + function in the struct dmx_demux. For example, + a demux interface might support Section filtering, but not PES + filtering. The API client is expected to check the value of any + function pointer before calling the function: the value of NULL means + that the “function is not available”. + Whenever the functions of the demux API modify shared data, + the possibilities of lost update and race condition problems should + be addressed, e.g. by protecting parts of code with mutexes. + Note that functions called from a bottom half context must not + sleep. Even a simple memory allocation without using GFP_ATOMIC can + result in a kernel thread being put to sleep if swapping is needed. + For example, the Linux kernel calls the functions of a network device + interface from a bottom half context. Thus, if a demux API function + is called from network device code, the function must not sleep. + + + +
+ Demux Callback API + This kernel-space API comprises the callback functions that + deliver filtered data to the demux client. Unlike the other DVB + kABIs, these functions are provided by the client and called from + the demux code. + The function pointers of this abstract interface are not + packed into a structure as in the other demux APIs, because the + callback functions are registered and used independent of each + other. As an example, it is possible for the API client to provide + several callback functions for receiving TS packets and no + callbacks for PES packets or sections. + The functions that implement the callback API need not be + re-entrant: when a demux driver calls one of these functions, + the driver is not allowed to call the function again before + the original call returns. If a callback is triggered by a + hardware interrupt, it is recommended to use the Linux + “bottom half” mechanism or start a tasklet instead of + making the callback function call directly from a hardware + interrupt. + This mechanism is implemented by + dmx_ts_cb() and + dmx_section_cb(). +

-Demux API -The demux API should be implemented for each demux in the system. It is used to select -the TS source of a demux and to manage the demux resources. When the demux -client allocates a resource via the demux API, it receives a pointer to the API of that -resource. - -Each demux receives its TS input from a DVB front-end or from memory, as set via the -demux API. In a system with more than one front-end, the API can be used to select one of -the DVB front-ends as a TS source for a demux, unless this is fixed in the HW platform. The -demux API only controls front-ends regarding their connections with demuxes; the APIs -used to set the other front-end parameters, such as tuning, are not defined in this -document. - -The functions that implement the abstract interface demux should be defined static or -module private and registered to the Demux Directory for external access. It is not necessary -to implement every function in the demux_t struct, however (for example, a demux interface -might support Section filtering, but not TS or PES filtering). The API client is expected to -check the value of any function pointer before calling the function: the value of NULL means -“function not available”. - -Whenever the functions of the demux API modify shared data, the possibilities of lost -update and race condition problems should be addressed, e.g. by protecting parts of code with -mutexes. This is especially important on multi-processor hosts. - -Note that functions called from a bottom half context must not sleep, at least in the 2.2.x -kernels. Even a simple memory allocation can result in a kernel thread being put to sleep if -swapping is needed. For example, the Linux kernel calls the functions of a network device -interface from a bottom half context. Thus, if a demux API function is called from network -device code, the function must not sleep. - - - -

-Demux Callback API -This kernel-space API comprises the callback functions that deliver filtered data to the -demux client. Unlike the other APIs, these API functions are provided by the client and called -from the demux code. - -The function pointers of this abstract interface are not packed into a structure as in the -other demux APIs, because the callback functions are registered and used independent -of each other. As an example, it is possible for the API client to provide several -callback functions for receiving TS packets and no callbacks for PES packets or -sections. - -The functions that implement the callback API need not be re-entrant: when a demux -driver calls one of these functions, the driver is not allowed to call the function again before -the original call returns. If a callback is triggered by a hardware interrupt, it is recommended -to use the Linux “bottom half” mechanism or start a tasklet instead of making the callback -function call directly from a hardware interrupt. - - -
dmx_ts_cb() -DESCRIPTION - - -This function, provided by the client of the demux API, is called from the - demux code. The function is only called when filtering on this TS feed has - been enabled using the start_filtering() function. - - -Any TS packets that match the filter settings are copied to a circular buffer. The - filtered TS packets are delivered to the client using this callback function. The - size of the circular buffer is controlled by the circular_buffer_size parameter - of the set() function in the TS Feed API. It is expected that the buffer1 and - buffer2 callback parameters point to addresses within the circular buffer, but - other implementations are also possible. Note that the called party should not - try to free the memory the buffer1 and buffer2 parameters point to. - - -When this function is called, the buffer1 parameter typically points to the - start of the first undelivered TS packet within a circular buffer. The buffer2 - buffer parameter is normally NULL, except when the received TS packets have - crossed the last address of the circular buffer and ”wrapped” to the beginning - of the buffer. In the latter case the buffer1 parameter would contain an address - within the circular buffer, while the buffer2 parameter would contain the first - address of the circular buffer. - - -The number of bytes delivered with this function (i.e. buffer1_length + - buffer2_length) is usually equal to the value of callback_length parameter - given in the set() function, with one exception: if a timeout occurs before - receiving callback_length bytes of TS data, any undelivered packets are - immediately delivered to the client by calling this function. The timeout - duration is controlled by the set() function in the TS Feed API. - - -If a TS packet is received with errors that could not be fixed by the TS-level - forward error correction (FEC), the Transport_error_indicator flag of the TS - packet header should be set. The TS packet should not be discarded, as - the error can possibly be corrected by a higher layer protocol. If the called - party is slow in processing the callback, it is possible that the circular buffer - eventually fills up. If this happens, the demux driver should discard any TS - packets received while the buffer is full. The error should be indicated to the - client on the next callback by setting the success parameter to the value of - DMX_OVERRUN_ERROR. - - -The type of data returned to the callback can be selected by the new - function int (*set_type) (struct dmx_ts_feed_s* feed, int type, dmx_ts_pes_t - pes_type) which is part of the dmx_ts_feed_s struct (also cf. to the - include file ost/demux.h) The type parameter decides if the raw TS packet - (TS_PACKET) or just the payload (TS_PACKET—TS_PAYLOAD_ONLY) - should be returned. If additionally the TS_DECODER bit is set the stream - will also be sent to the hardware MPEG decoder. In this case, the second - flag decides as what kind of data the stream should be interpreted. The - possible choices are one of DMX_TS_PES_AUDIO, DMX_TS_PES_VIDEO, - DMX_TS_PES_TELETEXT, DMX_TS_PES_SUBTITLE, - DMX_TS_PES_PCR, or DMX_TS_PES_OTHER. - - -SYNOPSIS - - -int dmx_ts_cb(__u8⋆ buffer1, size_t buffer1_length, - __u8⋆ buffer2, size_t buffer2_length, dmx_ts_feed_t⋆ - source, dmx_success_t success); - - -PARAMETERS - - -__u8* buffer1 - -Pointer to the start of the filtered TS packets. - - -size_t buffer1_length - -Length of the TS data in buffer1. - - -__u8* buffer2 - -Pointer to the tail of the filtered TS packets, or NULL. - - -size_t buffer2_length - -Length of the TS data in buffer2. - - -dmx_ts_feed_t* - source - -Indicates which TS feed is the source of the callback. - - -dmx_success_t - success - -Indicates if there was an error in TS reception. - - -RETURNS - - -0 - -Continue filtering. - - --1 - -Stop filtering - has the same effect as a call to - stop_filtering() on the TS Feed API. - - - -
dmx_section_cb() -DESCRIPTION - - -This function, provided by the client of the demux API, is called from the - demux code. The function is only called when filtering of sections has been - enabled using the function start_filtering() of the section feed API. When the - demux driver has received a complete section that matches at least one section - filter, the client is notified via this callback function. Normally this function is - called for each received section; however, it is also possible to deliver multiple - sections with one callback, for example when the system load is high. If an - error occurs while receiving a section, this function should be called with - the corresponding error type set in the success field, whether or not there is - data to deliver. The Section Feed implementation should maintain a circular - buffer for received sections. However, this is not necessary if the Section Feed - API is implemented as a client of the TS Feed API, because the TS Feed - implementation then buffers the received data. The size of the circular buffer - can be configured using the set() function in the Section Feed API. If there - is no room in the circular buffer when a new section is received, the section - must be discarded. If this happens, the value of the success parameter should - be DMX_OVERRUN_ERROR on the next callback. - - -SYNOPSIS - - -int dmx_section_cb(__u8⋆ buffer1, size_t - buffer1_length, __u8⋆ buffer2, size_t - buffer2_length, dmx_section_filter_t⋆ source, - dmx_success_t success); - - -PARAMETERS - - -__u8* buffer1 - -Pointer to the start of the filtered section, e.g. within the - circular buffer of the demux driver. - - -size_t buffer1_length - -Length of the filtered section data in buffer1, including - headers and CRC. - - -__u8* buffer2 - -Pointer to the tail of the filtered section data, or NULL. - Useful to handle the wrapping of a circular buffer. - - -size_t buffer2_length - -Length of the filtered section data in buffer2, including - headers and CRC. - - -dmx_section_filter_t* - filter - -Indicates the filter that triggered the callback. - - -dmx_success_t - success - -Indicates if there was an error in section reception. - - -RETURNS - - -0 - -Continue filtering. - - --1 - -Stop filtering - has the same effect as a call to - stop_filtering() on the Section Feed API. - - -

-Section Feed API -A section feed is a resource consisting of a PID filter and a set of section filters. Using this -API, the client can set the properties of a section feed and to start/stop filtering. The API is -defined as an abstract interface of the type dmx_section_feed_t. The functions that implement -the interface should be defined static or module private. The client can get the handle of -a section feed API by calling the function allocate_section_feed() in the demux -API. - -On demux platforms that provide section filtering in hardware, the Section Feed API -implementation provides a software wrapper for the demux hardware. Other platforms may -support only PID filtering in hardware, requiring that TS packets are converted to sections in -software. In the latter case the Section Feed API implementation can be a client of the TS -Feed API. - - -

allocate_filter() -DESCRIPTION - - -This function is used to allocate a section filter on the demux. It should only be - called when no filtering is in progress on this section feed. If a filter cannot be - allocated, the function fails with -ENOSPC. See in section ?? for the format of - the section filter. - - -The bitfields filter_mask and filter_value should only be modified when no - filtering is in progress on this section feed. filter_mask controls which bits of - filter_value are compared with the section headers/payload. On a binary value - of 1 in filter_mask, the corresponding bits are compared. The filter only accepts - sections that are equal to filter_value in all the tested bit positions. Any changes - to the values of filter_mask and filter_value are guaranteed to take effect only - when the start_filtering() function is called next time. The parent pointer in - the struct is initialized by the API implementation to the value of the feed - parameter. The priv pointer is not used by the API implementation, and can - thus be freely utilized by the caller of this function. Any data pointed to by the - priv pointer is available to the recipient of the dmx_section_cb() function call. - - -While the maximum section filter length (DMX_MAX_FILTER_SIZE) is - currently set at 16 bytes, hardware filters of that size are not available on all - platforms. Therefore, section filtering will often take place first in hardware, - followed by filtering in software for the header bytes that were not covered - by a hardware filter. The filter_mask field can be checked to determine how - many bytes of the section filter are actually used, and if the hardware filter will - suffice. Additionally, software-only section filters can optionally be allocated - to clients when all hardware section filters are in use. Note that on most demux - hardware it is not possible to filter on the section_length field of the section - header – thus this field is ignored, even though it is included in filter_value and - filter_mask fields. - - -SYNOPSIS - - -int allocate_filter(dmx_section_feed_t⋆ feed, - dmx_section_filter_t⋆⋆ filter); - - -PARAMETERS - - -dmx_section_feed_t* - feed - -Pointer to the section feed API and instance data. - - -dmx_section_filter_t** - filter - -Pointer to the allocated filter. - - -RETURNS - - -0 - -The function was completed without errors. - - --ENOSPC - -No filters of given type and length available. - - --EINVAL - -Bad parameters. - - - -

Well before we get to symlinks we have +another major division based on the VFS's approach to locking which +will allow us to review "REF-walk" and "RCU-walk" separately. But we +are getting ahead of ourselves. There are some important low level +distinctions we need to clarify first. + +There are two sorts of ... +-------------------------- + +[`openat()`]: http://man7.org/linux/man-pages/man2/openat.2.html + +Pathnames (sometimes "file names"), used to identify objects in the +filesystem, will be familiar to most readers. They contain two sorts +of elements: "slashes" that are sequences of one or more "`/`" +characters, and "components" that are sequences of one or more +non-"`/`" characters. These form two kinds of paths. Those that +start with slashes are "absolute" and start from the filesystem root. +The others are "relative" and start from the current directory, or +from some other location specified by a file descriptor given to a +"xxx`at`" system call such as "[`openat()`]". + +[`execveat()`]: http://man7.org/linux/man-pages/man2/execveat.2.html + +It is tempting to describe the second kind as starting with a +component, but that isn't always accurate: a pathname can lack both +slashes and components, it can be empty, in other words. This is +generally forbidden in POSIX, but some of those "xxx`at`" system calls +in Linux permit it when the `AT_EMPTY_PATH` flag is given. For +example, if you have an open file descriptor on an executable file you +can execute it by calling [`execveat()`] passing the file descriptor, +an empty path, and the `AT_EMPTY_PATH` flag. + +These paths can be divided into two sections: the final component and +everything else. The "everything else" is the easy bit. In all cases +it must identify a directory that already exists, otherwise an error +such as `ENOENT` or `ENOTDIR` will be reported. + +The final component is not so simple. Not only do different system +calls interpret it quite differently (e.g. some create it, some do +not), but it might not even exist: neither the empty pathname nor the +pathname that is just slashes have a final component. If it does +exist, it could be "`.`" or "`..`" which are handled quite differently +from other components. + +[POSIX]: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_12 + +If a pathname ends with a slash, such as "`/tmp/foo/`" it might be +tempting to consider that to have an empty final component. In many +ways that would lead to correct results, but not always. In +particular, `mkdir()` and `rmdir()` each create or remove a directory named +by the final component, and they are required to work with pathnames +ending in "`/`". According to [POSIX] + +> A pathname that contains at least one non- <slash> character and +> that ends with one or more trailing <slash> characters shall not +> be resolved successfully unless the last pathname component before +> the trailing characters names an existing directory or a +> directory entry that is to be created for a directory immediately +> after the pathname is resolved. + +The Linux pathname walking code (mostly in `fs/namei.c`) deals with +all of these issues: breaking the path into components, handling the +"everything else" quite separately from the final component, and +checking that the trailing slash is not used where it isn't +permitted. It also addresses the important issue of concurrent +access. + +While one process is looking up a pathname, another might be making +changes that affect that lookup. One fairly extreme case is that if +"a/b" were renamed to "a/c/b" while another process were looking up +"a/b/..", that process might successfully resolve on "a/c". +Most races are much more subtle, and a big part of the task of +pathname lookup is to prevent them from having damaging effects. Many +of the possible races are seen most clearly in the context of the +"dcache" and an understanding of that is central to understanding +pathname lookup. + +More than just a cache. +----------------------- + +The "dcache" caches information about names in each filesystem to +make them quickly available for lookup. Each entry (known as a +"dentry") contains three significant fields: a component name, a +pointer to a parent dentry, and a pointer to the "inode" which +contains further information about the object in that parent with +the given name. The inode pointer can be `NULL` indicating that the +name doesn't exist in the parent. While there can be linkage in the +dentry of a directory to the dentries of the children, that linkage is +not used for pathname lookup, and so will not be considered here. + +The dcache has a number of uses apart from accelerating lookup. One +that will be particularly relevant is that it is closely integrated +with the mount table that records which filesystem is mounted where. +What the mount table actually stores is which dentry is mounted on top +of which other dentry. + +When considering the dcache, we have another of our "two types" +distinctions: there are two types of filesystems. + +Some filesystems ensure that the information in the dcache is always +completely accurate (though not necessarily complete). This can allow +the VFS to determine if a particular file does or doesn't exist +without checking with the filesystem, and means that the VFS can +protect the filesystem against certain races and other problems. +These are typically "local" filesystems such as ext3, XFS, and Btrfs. + +Other filesystems don't provide that guarantee because they cannot. +These are typically filesystems that are shared across a network, +whether remote filesystems like NFS and 9P, or cluster filesystems +like ocfs2 or cephfs. These filesystems allow the VFS to revalidate +cached information, and must provide their own protection against +awkward races. The VFS can detect these filesystems by the +`DCACHE_OP_REVALIDATE` flag being set in the dentry. + +REF-walk: simple concurrency management with refcounts and spinlocks +-------------------------------------------------------------------- + +With all of those divisions carefully classified, we can now start +looking at the actual process of walking along a path. In particular +we will start with the handling of the "everything else" part of a +pathname, and focus on the "REF-walk" approach to concurrency +management. This code is found in the `link_path_walk()` function, if +you ignore all the places that only run when "`LOOKUP_RCU`" +(indicating the use of RCU-walk) is set. + +[Meet the Lockers]: https://lwn.net/Articles/453685/ + +REF-walk is fairly heavy-handed with locks and reference counts. Not +as heavy-handed as in the old "big kernel lock" days, but certainly not +afraid of taking a lock when one is needed. It uses a variety of +different concurrency controls. A background understanding of the +various primitives is assumed, or can be gleaned from elsewhere such +as in [Meet the Lockers]. + +The locking mechanisms used by REF-walk include: + +### dentry->d_lockref ### + +This uses the lockref primitive to provide both a spinlock and a +reference count. The special-sauce of this primitive is that the +conceptual sequence "lock; inc_ref; unlock;" can often be performed +with a single atomic memory operation. + +Holding a reference on a dentry ensures that the dentry won't suddenly +be freed and used for something else, so the values in various fields +will behave as expected. It also protects the `->d_inode` reference +to the inode to some extent. + +The association between a dentry and its inode is fairly permanent. +For example, when a file is renamed, the dentry and inode move +together to the new location. When a file is created the dentry will +initially be negative (i.e. `d_inode` is `NULL`), and will be assigned +to the new inode as part of the act of creation. + +When a file is deleted, this can be reflected in the cache either by +setting `d_inode` to `NULL`, or by removing it from the hash table +(described shortly) used to look up the name in the parent directory. +If the dentry is still in use the second option is used as it is +perfectly legal to keep using an open file after it has been deleted +and having the dentry around helps. If the dentry is not otherwise in +use (i.e. if the refcount in `d_lockref` is one), only then will +`d_inode` be set to `NULL`. Doing it this way is more efficient for a +very common case. + +So as long as a counted reference is held to a dentry, a non-`NULL` `->d_inode` +value will never be changed. + +### dentry->d_lock ### + +`d_lock` is a synonym for the spinlock that is part of `d_lockref` above. +For our purposes, holding this lock protects against the dentry being +renamed or unlinked. In particular, its parent (`d_parent`), and its +name (`d_name`) cannot be changed, and it cannot be removed from the +dentry hash table. + +When looking for a name in a directory, REF-walk takes `d_lock` on +each candidate dentry that it finds in the hash table and then checks +that the parent and name are correct. So it doesn't lock the parent +while searching in the cache; it only locks children. + +When looking for the parent for a given name (to handle "`..`"), +REF-walk can take `d_lock` to get a stable reference to `d_parent`, +but it first tries a more lightweight approach. As seen in +`dget_parent()`, if a reference can be claimed on the parent, and if +subsequently `d_parent` can be seen to have not changed, then there is +no need to actually take the lock on the child. + +### rename_lock ### + +Looking up a given name in a given directory involves computing a hash +from the two values (the name and the dentry of the directory), +accessing that slot in a hash table, and searching the linked list +that is found there. + +When a dentry is renamed, the name and the parent dentry can both +change so the hash will almost certainly change too. This would move the +dentry to a different chain in the hash table. If a filename search +happened to be looking at a dentry that was moved in this way, +it might end up continuing the search down the wrong chain, +and so miss out on part of the correct chain. + +The name-lookup process (`d_lookup()`) does _not_ try to prevent this +from happening, but only to detect when it happens. +`rename_lock` is a seqlock that is updated whenever any dentry is +renamed. If `d_lookup` finds that a rename happened while it +unsuccessfully scanned a chain in the hash table, it simply tries +again. + +### inode->i_mutex ### + +`i_mutex` is a mutex that serializes all changes to a particular +directory. This ensures that, for example, an `unlink()` and a `rename()` +cannot both happen at the same time. It also keeps the directory +stable while the filesystem is asked to look up a name that is not +currently in the dcache. + +This has a complementary role to that of `d_lock`: `i_mutex` on a +directory protects all of the names in that directory, while `d_lock` +on a name protects just one name in a directory. Most changes to the +dcache hold `i_mutex` on the relevant directory inode and briefly take +`d_lock` on one or more the dentries while the change happens. One +exception is when idle dentries are removed from the dcache due to +memory pressure. This uses `d_lock`, but `i_mutex` plays no role. + +The mutex affects pathname lookup in two distinct ways. Firstly it +serializes lookup of a name in a directory. `walk_component()` uses +`lookup_fast()` first which, in turn, checks to see if the name is in the cache, +using only `d_lock` locking. If the name isn't found, then `walk_component()` +falls back to `lookup_slow()` which takes `i_mutex`, checks again that +the name isn't in the cache, and then calls in to the filesystem to get a +definitive answer. A new dentry will be added to the cache regardless of +the result. + +Secondly, when pathname lookup reaches the final component, it will +sometimes need to take `i_mutex` before performing the last lookup so +that the required exclusion can be achieved. How path lookup chooses +to take, or not take, `i_mutex` is one of the +issues addressed in a subsequent section. + +### mnt->mnt_count ### + +`mnt_count` is a per-CPU reference counter on "`mount`" structures. +Per-CPU here means that incrementing the count is cheap as it only +uses CPU-local memory, but checking if the count is zero is expensive as +it needs to check with every CPU. Taking a `mnt_count` reference +prevents the mount structure from disappearing as the result of regular +unmount operations, but does not prevent a "lazy" unmount. So holding +`mnt_count` doesn't ensure that the mount remains in the namespace and, +in particular, doesn't stabilize the link to the mounted-on dentry. It +does, however, ensure that the `mount` data structure remains coherent, +and it provides a reference to the root dentry of the mounted +filesystem. So a reference through `->mnt_count` provides a stable +reference to the mounted dentry, but not the mounted-on dentry. + +### mount_lock ### + +`mount_lock` is a global seqlock, a bit like `rename_lock`. It can be used to +check if any change has been made to any mount points. + +While walking down the tree (away from the root) this lock is used when +crossing a mount point to check that the crossing was safe. That is, +the value in the seqlock is read, then the code finds the mount that +is mounted on the current directory, if there is one, and increments +the `mnt_count`. Finally the value in `mount_lock` is checked against +the old value. If there is no change, then the crossing was safe. If there +was a change, the `mnt_count` is decremented and the whole process is +retried. + +When walking up the tree (towards the root) by following a ".." link, +a little more care is needed. In this case the seqlock (which +contains both a counter and a spinlock) is fully locked to prevent +any changes to any mount points while stepping up. This locking is +needed to stabilize the link to the mounted-on dentry, which the +refcount on the mount itself doesn't ensure. + +### RCU ### + +Finally the global (but extremely lightweight) RCU read lock is held +from time to time to ensure certain data structures don't get freed +unexpectedly. + +In particular it is held while scanning chains in the dcache hash +table, and the mount point hash table. + +Bringing it together with `struct nameidata` +-------------------------------------------- + +[First edition Unix]: http://minnie.tuhs.org/cgi-bin/utree.pl?file=V1/u2.s + +Throughout the process of walking a path, the current status is stored +in a `struct nameidata`, "namei" being the traditional name - dating +all the way back to [First Edition Unix] - of the function that +converts a "name" to an "inode". `struct nameidata` contains (among +other fields): + +### `struct path path` ### + +A `path` contains a `struct vfsmount` (which is +embedded in a `struct mount`) and a `struct dentry`. Together these +record the current status of the walk. They start out referring to the +starting point (the current working directory, the root directory, or some other +directory identified by a file descriptor), and are updated on each +step. A reference through `d_lockref` and `mnt_count` is always +held. + +### `struct qstr last` ### + +This is a string together with a length (i.e. _not_ `nul` terminated) +that is the "next" component in the pathname. + +### `int last_type` ### + +This is one of `LAST_NORM`, `LAST_ROOT`, `LAST_DOT`, `LAST_DOTDOT`, or +`LAST_BIND`. The `last` field is only valid if the type is +`LAST_NORM`. `LAST_BIND` is used when following a symlink and no +components of the symlink have been processed yet. Others should be +fairly self-explanatory. + +### `struct path root` ### + +This is used to hold a reference to the effective root of the +filesystem. Often that reference won't be needed, so this field is +only assigned the first time it is used, or when a non-standard root +is requested. Keeping a reference in the `nameidata` ensures that +only one root is in effect for the entire path walk, even if it races +with a `chroot()` system call. + +The root is needed when either of two conditions holds: (1) either the +pathname or a symbolic link starts with a "'/'", or (2) a "`..`" +component is being handled, since "`..`" from the root must always stay +at the root. The value used is usually the current root directory of +the calling process. An alternate root can be provided as when +`sysctl()` calls `file_open_root()`, and when NFSv4 or Btrfs call +`mount_subtree()`. In each case a pathname is being looked up in a very +specific part of the filesystem, and the lookup must not be allowed to +escape that subtree. It works a bit like a local `chroot()`. + +Ignoring the handling of symbolic links, we can now describe the +"`link_path_walk()`" function, which handles the lookup of everything +except the final component as: + +> Given a path (`name`) and a nameidata structure (`nd`), check that the +> current directory has execute permission and then advance `name` +> over one component while updating `last_type` and `last`. If that +> was the final component, then return, otherwise call +> `walk_component()` and repeat from the top. + +`walk_component()` is even easier. If the component is `LAST_DOTS`, +it calls `handle_dots()` which does the necessary locking as already +described. If it finds a `LAST_NORM` component it first calls +"`lookup_fast()`" which only looks in the dcache, but will ask the +filesystem to revalidate the result if it is that sort of filesystem. +If that doesn't get a good result, it calls "`lookup_slow()`" which +takes the `i_mutex`, rechecks the cache, and then asks the filesystem +to find a definitive answer. Each of these will call +`follow_managed()` (as described below) to handle any mount points. + +In the absence of symbolic links, `walk_component()` creates a new +`struct path` containing a counted reference to the new dentry and a +reference to the new `vfsmount` which is only counted if it is +different from the previous `vfsmount`. It then calls +`path_to_nameidata()` to install the new `struct path` in the +`struct nameidata` and drop the unneeded references. + +This "hand-over-hand" sequencing of getting a reference to the new +dentry before dropping the reference to the previous dentry may +seem obvious, but is worth pointing out so that we will recognize its +analogue in the "RCU-walk" version. + +Handling the final component. +----------------------------- + +`link_path_walk()` only walks as far as setting `nd->last` and +`nd->last_type` to refer to the final component of the path. It does +not call `walk_component()` that last time. Handling that final +component remains for the caller to sort out. Those callers are +`path_lookupat()`, `path_parentat()`, `path_mountpoint()` and +`path_openat()` each of which handles the differing requirements of +different system calls. + +`path_parentat()` is clearly the simplest - it just wraps a little bit +of housekeeping around `link_path_walk()` and returns the parent +directory and final component to the caller. The caller will be either +aiming to create a name (via `filename_create()`) or remove or rename +a name (in which case `user_path_parent()` is used). They will use +`i_mutex` to exclude other changes while they validate and then +perform their operation. + +`path_lookupat()` is nearly as simple - it is used when an existing +object is wanted such as by `stat()` or `chmod()`. It essentially just +calls `walk_component()` on the final component through a call to +`lookup_last()`. `path_lookupat()` returns just the final dentry. + +`path_mountpoint()` handles the special case of unmounting which must +not try to revalidate the mounted filesystem. It effectively +contains, through a call to `mountpoint_last()`, an alternate +implementation of `lookup_slow()` which skips that step. This is +important when unmounting a filesystem that is inaccessible, such as +one provided by a dead NFS server. + +Finally `path_openat()` is used for the `open()` system call; it +contains, in support functions starting with "`do_last()`", all the +complexity needed to handle the different subtleties of O_CREAT (with +or without O_EXCL), final "`/`" characters, and trailing symbolic +links. We will revisit this in the final part of this series, which +focuses on those symbolic links. "`do_last()`" will sometimes, but +not always, take `i_mutex`, depending on what it finds. + +Each of these, or the functions which call them, need to be alert to +the possibility that the final component is not `LAST_NORM`. If the +goal of the lookup is to create something, then any value for +`last_type` other than `LAST_NORM` will result in an error. For +example if `path_parentat()` reports `LAST_DOTDOT`, then the caller +won't try to create that name. They also check for trailing slashes +by testing `last.name[last.len]`. If there is any character beyond +the final component, it must be a trailing slash. + +Revalidation and automounts +--------------------------- + +Apart from symbolic links, there are only two parts of the "REF-walk" +process not yet covered. One is the handling of stale cache entries +and the other is automounts. + +On filesystems that require it, the lookup routines will call the +`->d_revalidate()` dentry method to ensure that the cached information +is current. This will often confirm validity or update a few details +from a server. In some cases it may find that there has been change +further up the path and that something that was thought to be valid +previously isn't really. When this happens the lookup of the whole +path is aborted and retried with the "`LOOKUP_REVAL`" flag set. This +forces revalidation to be more thorough. We will see more details of +this retry process in the next article. + +Automount points are locations in the filesystem where an attempt to +lookup a name can trigger changes to how that lookup should be +handled, in particular by mounting a filesystem there. These are +covered in greater detail in autofs4.txt in the Linux documentation +tree, but a few notes specifically related to path lookup are in order +here. + +The Linux VFS has a concept of "managed" dentries which is reflected +in function names such as "`follow_managed()`". There are three +potentially interesting things about these dentries corresponding +to three different flags that might be set in `dentry->d_flags`: + +### `DCACHE_MANAGE_TRANSIT` ### + +If this flag has been set, then the filesystem has requested that the +`d_manage()` dentry operation be called before handling any possible +mount point. This can perform two particular services: + +It can block to avoid races. If an automount point is being +unmounted, the `d_manage()` function will usually wait for that +process to complete before letting the new lookup proceed and possibly +trigger a new automount. + +It can selectively allow only some processes to transit through a +mount point. When a server process is managing automounts, it may +need to access a directory without triggering normal automount +processing. That server process can identify itself to the `autofs` +filesystem, which will then give it a special pass through +`d_manage()` by returning `-EISDIR`. + +### `DCACHE_MOUNTED` ### + +This flag is set on every dentry that is mounted on. As Linux +supports multiple filesystem namespaces, it is possible that the +dentry may not be mounted on in *this* namespace, just in some +other. So this flag is seen as a hint, not a promise. + +If this flag is set, and `d_manage()` didn't return `-EISDIR`, +`lookup_mnt()` is called to examine the mount hash table (honoring the +`mount_lock` described earlier) and possibly return a new `vfsmount` +and a new `dentry` (both with counted references). + +### `DCACHE_NEED_AUTOMOUNT` ### + +If `d_manage()` allowed us to get this far, and `lookup_mnt()` didn't +find a mount point, then this flag causes the `d_automount()` dentry +operation to be called. + +The `d_automount()` operation can be arbitrarily complex and may +communicate with server processes etc. but it should ultimately either +report that there was an error, that there was nothing to mount, or +should provide an updated `struct path` with new `dentry` and `vfsmount`. + +In the latter case, `finish_automount()` will be called to safely +install the new mount point into the mount table. + +There is no new locking of import here and it is important that no +locks (only counted references) are held over this processing due to +the very real possibility of extended delays. +This will become more important next time when we examine RCU-walk +which is particularly sensitive to delays. + +RCU-walk - faster pathname lookup in Linux +========================================== + +RCU-walk is another algorithm for performing pathname lookup in Linux. +It is in many ways similar to REF-walk and the two share quite a bit +of code. The significant difference in RCU-walk is how it allows for +the possibility of concurrent access. + +We noted that REF-walk is complex because there are numerous details +and special cases. RCU-walk reduces this complexity by simply +refusing to handle a number of cases -- it instead falls back to +REF-walk. The difficulty with RCU-walk comes from a different +direction: unfamiliarity. The locking rules when depending on RCU are +quite different from traditional locking, so we will spend a little extra +time when we come to those. + +Clear demarcation of roles +-------------------------- + +The easiest way to manage concurrency is to forcibly stop any other +thread from changing the data structures that a given thread is +looking at. In cases where no other thread would even think of +changing the data and lots of different threads want to read at the +same time, this can be very costly. Even when using locks that permit +multiple concurrent readers, the simple act of updating the count of +the number of current readers can impose an unwanted cost. So the +goal when reading a shared data structure that no other process is +changing is to avoid writing anything to memory at all. Take no +locks, increment no counts, leave no footprints. + +The REF-walk mechanism already described certainly doesn't follow this +principle, but then it is really designed to work when there may well +be other threads modifying the data. RCU-walk, in contrast, is +designed for the common situation where there are lots of frequent +readers and only occasional writers. This may not be common in all +parts of the filesystem tree, but in many parts it will be. For the +other parts it is important that RCU-walk can quickly fall back to +using REF-walk. + +Pathname lookup always starts in RCU-walk mode but only remains there +as long as what it is looking for is in the cache and is stable. It +dances lightly down the cached filesystem image, leaving no footprints +and carefully watching where it is, to be sure it doesn't trip. If it +notices that something has changed or is changing, or if something +isn't in the cache, then it tries to stop gracefully and switch to +REF-walk. + +This stopping requires getting a counted reference on the current +`vfsmount` and `dentry`, and ensuring that these are still valid - +that a path walk with REF-walk would have found the same entries. +This is an invariant that RCU-walk must guarantee. It can only make +decisions, such as selecting the next step, that are decisions which +REF-walk could also have made if it were walking down the tree at the +same time. If the graceful stop succeeds, the rest of the path is +processed with the reliable, if slightly sluggish, REF-walk. If +RCU-walk finds it cannot stop gracefully, it simply gives up and +restarts from the top with REF-walk. + +This pattern of "try RCU-walk, if that fails try REF-walk" can be +clearly seen in functions like `filename_lookup()`, +`filename_parentat()`, `filename_mountpoint()`, +`do_filp_open()`, and `do_file_open_root()`. These five +correspond roughly to the four `path_`* functions we met earlier, +each of which calls `link_path_walk()`. The `path_*` functions are +called using different mode flags until a mode is found which works. +They are first called with `LOOKUP_RCU` set to request "RCU-walk". If +that fails with the error `ECHILD` they are called again with no +special flag to request "REF-walk". If either of those report the +error `ESTALE` a final attempt is made with `LOOKUP_REVAL` set (and no +`LOOKUP_RCU`) to ensure that entries found in the cache are forcibly +revalidated - normally entries are only revalidated if the filesystem +determines that they are too old to trust. + +The `LOOKUP_RCU` attempt may drop that flag internally and switch to +REF-walk, but will never then try to switch back to RCU-walk. Places +that trip up RCU-walk are much more likely to be near the leaves and +so it is very unlikely that there will be much, if any, benefit from +switching back. + +RCU and seqlocks: fast and light +-------------------------------- + +RCU is, unsurprisingly, critical to RCU-walk mode. The +`rcu_read_lock()` is held for the entire time that RCU-walk is walking +down a path. The particular guarantee it provides is that the key +data structures - dentries, inodes, super_blocks, and mounts - will +not be freed while the lock is held. They might be unlinked or +invalidated in one way or another, but the memory will not be +repurposed so values in various fields will still be meaningful. This +is the only guarantee that RCU provides; everything else is done using +seqlocks. + +As we saw above, REF-walk holds a counted reference to the current +dentry and the current vfsmount, and does not release those references +before taking references to the "next" dentry or vfsmount. It also +sometimes takes the `d_lock` spinlock. These references and locks are +taken to prevent certain changes from happening. RCU-walk must not +take those references or locks and so cannot prevent such changes. +Instead, it checks to see if a change has been made, and aborts or +retries if it has. + +To preserve the invariant mentioned above (that RCU-walk may only make +decisions that REF-walk could have made), it must make the checks at +or near the same places that REF-walk holds the references. So, when +REF-walk increments a reference count or takes a spinlock, RCU-walk +samples the status of a seqlock using `read_seqcount_begin()` or a +similar function. When REF-walk decrements the count or drops the +lock, RCU-walk checks if the sampled status is still valid using +`read_seqcount_retry()` or similar. + +However, there is a little bit more to seqlocks than that. If +RCU-walk accesses two different fields in a seqlock-protected +structure, or accesses the same field twice, there is no a priori +guarantee of any consistency between those accesses. When consistency +is needed - which it usually is - RCU-walk must take a copy and then +use `read_seqcount_retry()` to validate that copy. + +`read_seqcount_retry()` not only checks the sequence number, but also +imposes a memory barrier so that no memory-read instruction from +*before* the call can be delayed until *after* the call, either by the +CPU or by the compiler. A simple example of this can be seen in +`slow_dentry_cmp()` which, for filesystems which do not use simple +byte-wise name equality, calls into the filesystem to compare a name +against a dentry. The length and name pointer are copied into local +variables, then `read_seqcount_retry()` is called to confirm the two +are consistent, and only then is `->d_compare()` called. When +standard filename comparison is used, `dentry_cmp()` is called +instead. Notably it does _not_ use `read_seqcount_retry()`, but +instead has a large comment explaining why the consistency guarantee +isn't necessary. A subsequent `read_seqcount_retry()` will be +sufficient to catch any problem that could occur at this point. + +With that little refresher on seqlocks out of the way we can look at +the bigger picture of how RCU-walk uses seqlocks. + +### `mount_lock` and `nd->m_seq` ### + +We already met the `mount_lock` seqlock when REF-walk used it to +ensure that crossing a mount point is performed safely. RCU-walk uses +it for that too, but for quite a bit more. + +Instead of taking a counted reference to each `vfsmount` as it +descends the tree, RCU-walk samples the state of `mount_lock` at the +start of the walk and stores this initial sequence number in the +`struct nameidata` in the `m_seq` field. This one lock and one +sequence number are used to validate all accesses to all `vfsmounts`, +and all mount point crossings. As changes to the mount table are +relatively rare, it is reasonable to fall back on REF-walk any time +that any "mount" or "unmount" happens. + +`m_seq` is checked (using `read_seqretry()`) at the end of an RCU-walk +sequence, whether switching to REF-walk for the rest of the path or +when the end of the path is reached. It is also checked when stepping +down over a mount point (in `__follow_mount_rcu()`) or up (in +`follow_dotdot_rcu()`). If it is ever found to have changed, the +whole RCU-walk sequence is aborted and the path is processed again by +REF-walk. + +If RCU-walk finds that `mount_lock` hasn't changed then it can be sure +that, had REF-walk taken counted references on each vfsmount, the +results would have been the same. This ensures the invariant holds, +at least for vfsmount structures. + +### `dentry->d_seq` and `nd->seq`. ### + +In place of taking a count or lock on `d_reflock`, RCU-walk samples +the per-dentry `d_seq` seqlock, and stores the sequence number in the +`seq` field of the nameidata structure, so `nd->seq` should always be +the current sequence number of `nd->dentry`. This number needs to be +revalidated after copying, and before using, the name, parent, or +inode of the dentry. + +The handling of the name we have already looked at, and the parent is +only accessed in `follow_dotdot_rcu()` which fairly trivially follows +the required pattern, though it does so for three different cases. + +When not at a mount point, `d_parent` is followed and its `d_seq` is +collected. When we are at a mount point, we instead follow the +`mnt->mnt_mountpoint` link to get a new dentry and collect its +`d_seq`. Then, after finally finding a `d_parent` to follow, we must +check if we have landed on a mount point and, if so, must find that +mount point and follow the `mnt->mnt_root` link. This would imply a +somewhat unusual, but certainly possible, circumstance where the +starting point of the path lookup was in part of the filesystem that +was mounted on, and so not visible from the root. + +The inode pointer, stored in `->d_inode`, is a little more +interesting. The inode will always need to be accessed at least +twice, once to determine if it is NULL and once to verify access +permissions. Symlink handling requires a validated inode pointer too. +Rather than revalidating on each access, a copy is made on the first +access and it is stored in the `inode` field of `nameidata` from where +it can be safely accessed without further validation. + +`lookup_fast()` is the only lookup routine that is used in RCU-mode, +`lookup_slow()` being too slow and requiring locks. It is in +`lookup_fast()` that we find the important "hand over hand" tracking +of the current dentry. + +The current `dentry` and current `seq` number are passed to +`__d_lookup_rcu()` which, on success, returns a new `dentry` and a +new `seq` number. `lookup_fast()` then copies the inode pointer and +revalidates the new `seq` number. It then validates the old `dentry` +with the old `seq` number one last time and only then continues. This +process of getting the `seq` number of the new dentry and then +checking the `seq` number of the old exactly mirrors the process of +getting a counted reference to the new dentry before dropping that for +the old dentry which we saw in REF-walk. + +### No `inode->i_mutex` or even `rename_lock` ### + +A mutex is a fairly heavyweight lock that can only be taken when it is +permissible to sleep. As `rcu_read_lock()` forbids sleeping, +`inode->i_mutex` plays no role in RCU-walk. If some other thread does +take `i_mutex` and modifies the directory in a way that RCU-walk needs +to notice, the result will be either that RCU-walk fails to find the +dentry that it is looking for, or it will find a dentry which +`read_seqretry()` won't validate. In either case it will drop down to +REF-walk mode which can take whatever locks are needed. + +Though `rename_lock` could be used by RCU-walk as it doesn't require +any sleeping, RCU-walk doesn't bother. REF-walk uses `rename_lock` to +protect against the possibility of hash chains in the dcache changing +while they are being searched. This can result in failing to find +something that actually is there. When RCU-walk fails to find +something in the dentry cache, whether it is really there or not, it +already drops down to REF-walk and tries again with appropriate +locking. This neatly handles all cases, so adding extra checks on +rename_lock would bring no significant value. + +`unlazy walk()` and `complete_walk()` +------------------------------------- + +That "dropping down to REF-walk" typically involves a call to +`unlazy_walk()`, so named because "RCU-walk" is also sometimes +referred to as "lazy walk". `unlazy_walk()` is called when +following the path down to the current vfsmount/dentry pair seems to +have proceeded successfully, but the next step is problematic. This +can happen if the next name cannot be found in the dcache, if +permission checking or name revalidation couldn't be achieved while +the `rcu_read_lock()` is held (which forbids sleeping), if an +automount point is found, or in a couple of cases involving symlinks. +It is also called from `complete_walk()` when the lookup has reached +the final component, or the very end of the path, depending on which +particular flavor of lookup is used. + +Other reasons for dropping out of RCU-walk that do not trigger a call +to `unlazy_walk()` are when some inconsistency is found that cannot be +handled immediately, such as `mount_lock` or one of the `d_seq` +seqlocks reporting a change. In these cases the relevant function +will return `-ECHILD` which will percolate up until it triggers a new +attempt from the top using REF-walk. + +For those cases where `unlazy_walk()` is an option, it essentially +takes a reference on each of the pointers that it holds (vfsmount, +dentry, and possibly some symbolic links) and then verifies that the +relevant seqlocks have not been changed. If there have been changes, +it, too, aborts with `-ECHILD`, otherwise the transition to REF-walk +has been a success and the lookup process continues. + +Taking a reference on those pointers is not quite as simple as just +incrementing a counter. That works to take a second reference if you +already have one (often indirectly through another object), but it +isn't sufficient if you don't actually have a counted reference at +all. For `dentry->d_lockref`, it is safe to increment the reference +counter to get a reference unless it has been explicitly marked as +"dead" which involves setting the counter to `-128`. +`lockref_get_not_dead()` achieves this. + +For `mnt->mnt_count` it is safe to take a reference as long as +`mount_lock` is then used to validate the reference. If that +validation fails, it may *not* be safe to just drop that reference in +the standard way of calling `mnt_put()` - an unmount may have +progressed too far. So the code in `legitimize_mnt()`, when it +finds that the reference it got might not be safe, checks the +`MNT_SYNC_UMOUNT` flag to determine if a simple `mnt_put()` is +correct, or if it should just decrement the count and pretend none of +this ever happened. + +Taking care in filesystems +--------------------------- + +RCU-walk depends almost entirely on cached information and often will +not call into the filesystem at all. However there are two places, +besides the already-mentioned component-name comparison, where the +file system might be included in RCU-walk, and it must know to be +careful. + +If the filesystem has non-standard permission-checking requirements - +such as a networked filesystem which may need to check with the server +- the `i_op->permission` interface might be called during RCU-walk. +In this case an extra "`MAY_NOT_BLOCK`" flag is passed so that it +knows not to sleep, but to return `-ECHILD` if it cannot complete +promptly. `i_op->permission` is given the inode pointer, not the +dentry, so it doesn't need to worry about further consistency checks. +However if it accesses any other filesystem data structures, it must +ensure they are safe to be accessed with only the `rcu_read_lock()` +held. This typically means they must be freed using `kfree_rcu()` or +similar. + +[`READ_ONCE()`]: https://lwn.net/Articles/624126/ + +If the filesystem may need to revalidate dcache entries, then +`d_op->d_revalidate` may be called in RCU-walk too. This interface +*is* passed the dentry but does not have access to the `inode` or the +`seq` number from the `nameidata`, so it needs to be extra careful +when accessing fields in the dentry. This "extra care" typically +involves using `ACCESS_ONCE()` or the newer [`READ_ONCE()`] to access +fields, and verifying the result is not NULL before using it. This +pattern can be see in `nfs_lookup_revalidate()`. + +A pair of patterns +------------------ + +In various places in the details of REF-walk and RCU-walk, and also in +the big picture, there are a couple of related patterns that are worth +being aware of. + +The first is "try quickly and check, if that fails try slowly". We +can see that in the high-level approach of first trying RCU-walk and +then trying REF-walk, and in places where `unlazy_walk()` is used to +switch to REF-walk for the rest of the path. We also saw it earlier +in `dget_parent()` when following a "`..`" link. It tries a quick way +to get a reference, then falls back to taking locks if needed. + +The second pattern is "try quickly and check, if that fails try +again - repeatedly". This is seen with the use of `rename_lock` and +`mount_lock` in REF-walk. RCU-walk doesn't make use of this pattern - +if anything goes wrong it is much safer to just abort and try a more +sedate approach. + +The emphasis here is "try quickly and check". It should probably be +"try quickly _and carefully,_ then check". The fact that checking is +needed is a reminder that the system is dynamic and only a limited +number of things are safe at all. The most likely cause of errors in +this whole process is assuming something is safe when in reality it +isn't. Careful consideration of what exactly guarantees the safety of +each access is sometimes necessary. + +A walk among the symlinks +========================= + +There are several basic issues that we will examine to understand the +handling of symbolic links: the symlink stack, together with cache +lifetimes, will help us understand the overall recursive handling of +symlinks and lead to the special care needed for the final component. +Then a consideration of access-time updates and summary of the various +flags controlling lookup will finish the story. + +The symlink stack +----------------- + +There are only two sorts of filesystem objects that can usefully +appear in a path prior to the final component: directories and symlinks. +Handling directories is quite straightforward: the new directory +simply becomes the starting point at which to interpret the next +component on the path. Handling symbolic links requires a bit more +work. + +Conceptually, symbolic links could be handled by editing the path. If +a component name refers to a symbolic link, then that component is +replaced by the body of the link and, if that body starts with a '/', +then all preceding parts of the path are discarded. This is what the +"`readlink -f`" command does, though it also edits out "`.`" and +"`..`" components. + +Directly editing the path string is not really necessary when looking +up a path, and discarding early components is pointless as they aren't +looked at anyway. Keeping track of all remaining components is +important, but they can of course be kept separately; there is no need +to concatenate them. As one symlink may easily refer to another, +which in turn can refer to a third, we may need to keep the remaining +components of several paths, each to be processed when the preceding +ones are completed. These path remnants are kept on a stack of +limited size. + +There are two reasons for placing limits on how many symlinks can +occur in a single path lookup. The most obvious is to avoid loops. +If a symlink referred to itself either directly or through +intermediaries, then following the symlink can never complete +successfully - the error `ELOOP` must be returned. Loops can be +detected without imposing limits, but limits are the simplest solution +and, given the second reason for restriction, quite sufficient. + +[outlined recently]: http://thread.gmane.org/gmane.linux.kernel/1934390/focus=1934550 + +The second reason was [outlined recently] by Linus: + +> Because it's a latency and DoS issue too. We need to react well to +> true loops, but also to "very deep" non-loops. It's not about memory +> use, it's about users triggering unreasonable CPU resources. + +Linux imposes a limit on the length of any pathname: `PATH_MAX`, which +is 4096. There are a number of reasons for this limit; not letting the +kernel spend too much time on just one path is one of them. With +symbolic links you can effectively generate much longer paths so some +sort of limit is needed for the same reason. Linux imposes a limit of +at most 40 symlinks in any one path lookup. It previously imposed a +further limit of eight on the maximum depth of recursion, but that was +raised to 40 when a separate stack was implemented, so there is now +just the one limit. + +The `nameidata` structure that we met in an earlier article contains a +small stack that can be used to store the remaining part of up to two +symlinks. In many cases this will be sufficient. If it isn't, a +separate stack is allocated with room for 40 symlinks. Pathname +lookup will never exceed that stack as, once the 40th symlink is +detected, an error is returned. + +It might seem that the name remnants are all that needs to be stored on +this stack, but we need a bit more. To see that, we need to move on to +cache lifetimes. + +Storage and lifetime of cached symlinks +--------------------------------------- + +Like other filesystem resources, such as inodes and directory +entries, symlinks are cached by Linux to avoid repeated costly access +to external storage. It is particularly important for RCU-walk to be +able to find and temporarily hold onto these cached entries, so that +it doesn't need to drop down into REF-walk. + +[object-oriented design pattern]: https://lwn.net/Articles/446317/ + +While each filesystem is free to make its own choice, symlinks are +typically stored in one of two places. Short symlinks are often +stored directly in the inode. When a filesystem allocates a `struct +inode` it typically allocates extra space to store private data (a +common [object-oriented design pattern] in the kernel). This will +sometimes include space for a symlink. The other common location is +in the page cache, which normally stores the content of files. The +pathname in a symlink can be seen as the content of that symlink and +can easily be stored in the page cache just like file content. + +When neither of these is suitable, the next most likely scenario is +that the filesystem will allocate some temporary memory and copy or +construct the symlink content into that memory whenever it is needed. + +When the symlink is stored in the inode, it has the same lifetime as +the inode which, itself, is protected by RCU or by a counted reference +on the dentry. This means that the mechanisms that pathname lookup +uses to access the dcache and icache (inode cache) safely are quite +sufficient for accessing some cached symlinks safely. In these cases, +the `i_link` pointer in the inode is set to point to wherever the +symlink is stored and it can be accessed directly whenever needed. + +When the symlink is stored in the page cache or elsewhere, the +situation is not so straightforward. A reference on a dentry or even +on an inode does not imply any reference on cached pages of that +inode, and even an `rcu_read_lock()` is not sufficient to ensure that +a page will not disappear. So for these symlinks the pathname lookup +code needs to ask the filesystem to provide a stable reference and, +significantly, needs to release that reference when it is finished +with it. + +Taking a reference to a cache page is often possible even in RCU-walk +mode. It does require making changes to memory, which is best avoided, +but that isn't necessarily a big cost and it is better than dropping +out of RCU-walk mode completely. Even filesystems that allocate +space to copy the symlink into can use `GFP_ATOMIC` to often successfully +allocate memory without the need to drop out of RCU-walk. If a +filesystem cannot successfully get a reference in RCU-walk mode, it +must return `-ECHILD` and `unlazy_walk()` will be called to return to +REF-walk mode in which the filesystem is allowed to sleep. + +The place for all this to happen is the `i_op->follow_link()` inode +method. In the present mainline code this is never actually called in +RCU-walk mode as the rewrite is not quite complete. It is likely that +in a future release this method will be passed an `inode` pointer when +called in RCU-walk mode so it both (1) knows to be careful, and (2) has the +validated pointer. Much like the `i_op->permission()` method we +looked at previously, `->follow_link()` would need to be careful that +all the data structures it references are safe to be accessed while +holding no counted reference, only the RCU lock. Though getting a +reference with `->follow_link()` is not yet done in RCU-walk mode, the +code is ready to release the reference when that does happen. + +This need to drop the reference to a symlink adds significant +complexity. It requires a reference to the inode so that the +`i_op->put_link()` inode operation can be called. In REF-walk, that +reference is kept implicitly through a reference to the dentry, so +keeping the `struct path` of the symlink is easiest. For RCU-walk, +the pointer to the inode is kept separately. To allow switching from +RCU-walk back to REF-walk in the middle of processing nested symlinks +we also need the seq number for the dentry so we can confirm that +switching back was safe. + +Finally, when providing a reference to a symlink, the filesystem also +provides an opaque "cookie" that must be passed to `->put_link()` so that it +knows what to free. This might be the allocated memory area, or a +pointer to the `struct page` in the page cache, or something else +completely. Only the filesystem knows what it is. + +In order for the reference to each symlink to be dropped when the walk completes, +whether in RCU-walk or REF-walk, the symlink stack needs to contain, +along with the path remnants: + +- the `struct path` to provide a reference to the inode in REF-walk +- the `struct inode *` to provide a reference to the inode in RCU-walk +- the `seq` to allow the path to be safely switched from RCU-walk to REF-walk +- the `cookie` that tells `->put_path()` what to put. + +This means that each entry in the symlink stack needs to hold five +pointers and an integer instead of just one pointer (the path +remnant). On a 64-bit system, this is about 40 bytes per entry; +with 40 entries it adds up to 1600 bytes total, which is less than +half a page. So it might seem like a lot, but is by no means +excessive. + +Note that, in a given stack frame, the path remnant (`name`) is not +part of the symlink that the other fields refer to. It is the remnant +to be followed once that symlink has been fully parsed. + +Following the symlink +--------------------- + +The main loop in `link_path_walk()` iterates seamlessly over all +components in the path and all of the non-final symlinks. As symlinks +are processed, the `name` pointer is adjusted to point to a new +symlink, or is restored from the stack, so that much of the loop +doesn't need to notice. Getting this `name` variable on and off the +stack is very straightforward; pushing and popping the references is +a little more complex. + +When a symlink is found, `walk_component()` returns the value `1` +(`0` is returned for any other sort of success, and a negative number +is, as usual, an error indicator). This causes `get_link()` to be +called; it then gets the link from the filesystem. Providing that +operation is successful, the old path `name` is placed on the stack, +and the new value is used as the `name` for a while. When the end of +the path is found (i.e. `*name` is `'\0'`) the old `name` is restored +off the stack and path walking continues. + +Pushing and popping the reference pointers (inode, cookie, etc.) is more +complex in part because of the desire to handle tail recursion. When +the last component of a symlink itself points to a symlink, we +want to pop the symlink-just-completed off the stack before pushing +the symlink-just-found to avoid leaving empty path remnants that would +just get in the way. + +It is most convenient to push the new symlink references onto the +stack in `walk_component()` immediately when the symlink is found; +`walk_component()` is also the last piece of code that needs to look at the +old symlink as it walks that last component. So it is quite +convenient for `walk_component()` to release the old symlink and pop +the references just before pushing the reference information for the +new symlink. It is guided in this by two flags; `WALK_GET`, which +gives it permission to follow a symlink if it finds one, and +`WALK_PUT`, which tells it to release the current symlink after it has been +followed. `WALK_PUT` is tested first, leading to a call to +`put_link()`. `WALK_GET` is tested subsequently (by +`should_follow_link()`) leading to a call to `pick_link()` which sets +up the stack frame. + +### Symlinks with no final component ### + +A pair of special-case symlinks deserve a little further explanation. +Both result in a new `struct path` (with mount and dentry) being set +up in the `nameidata`, and result in `get_link()` returning `NULL`. + +The more obvious case is a symlink to "`/`". All symlinks starting +with "`/`" are detected in `get_link()` which resets the `nameidata` +to point to the effective filesystem root. If the symlink only +contains "`/`" then there is nothing more to do, no components at all, +so `NULL` is returned to indicate that the symlink can be released and +the stack frame discarded. + +The other case involves things in `/proc` that look like symlinks but +aren't really. + +> $ ls -l /proc/self/fd/1 +> lrwx------ 1 neilb neilb 64 Jun 13 10:19 /proc/self/fd/1 -> /dev/pts/4 + +Every open file descriptor in any process is represented in `/proc` by +something that looks like a symlink. It is really a reference to the +target file, not just the name of it. When you `readlink` these +objects you get a name that might refer to the same file - unless it +has been unlinked or mounted over. When `walk_component()` follows +one of these, the `->follow_link()` method in "procfs" doesn't return +a string name, but instead calls `nd_jump_link()` which updates the +`nameidata` in place to point to that target. `->follow_link()` then +returns `NULL`. Again there is no final component and `get_link()` +reports this by leaving the `last_type` field of `nameidata` as +`LAST_BIND`. + +Following the symlink in the final component +-------------------------------------------- + +All this leads to `link_path_walk()` walking down every component, and +following all symbolic links it finds, until it reaches the final +component. This is just returned in the `last` field of `nameidata`. +For some callers, this is all they need; they want to create that +`last` name if it doesn't exist or give an error if it does. Other +callers will want to follow a symlink if one is found, and possibly +apply special handling to the last component of that symlink, rather +than just the last component of the original file name. These callers +potentially need to call `link_path_walk()` again and again on +successive symlinks until one is found that doesn't point to another +symlink. + +This case is handled by the relevant caller of `link_path_walk()`, such as +`path_lookupat()` using a loop that calls `link_path_walk()`, and then +handles the final component. If the final component is a symlink +that needs to be followed, then `trailing_symlink()` is called to set +things up properly and the loop repeats, calling `link_path_walk()` +again. This could loop as many as 40 times if the last component of +each symlink is another symlink. + +The various functions that examine the final component and possibly +report that it is a symlink are `lookup_last()`, `mountpoint_last()` +and `do_last()`, each of which use the same convention as +`walk_component()` of returning `1` if a symlink was found that needs +to be followed. + +Of these, `do_last()` is the most interesting as it is used for +opening a file. Part of `do_last()` runs with `i_mutex` held and this +part is in a separate function: `lookup_open()`. + +Explaining `do_last()` completely is beyond the scope of this article, +but a few highlights should help those interested in exploring the +code. + +1. Rather than just finding the target file, `do_last()` needs to open + it. If the file was found in the dcache, then `vfs_open()` is used for + this. If not, then `lookup_open()` will either call `atomic_open()` (if + the filesystem provides it) to combine the final lookup with the open, or + will perform the separate `lookup_real()` and `vfs_create()` steps + directly. In the later case the actual "open" of this newly found or + created file will be performed by `vfs_open()`, just as if the name + were found in the dcache. + +2. `vfs_open()` can fail with `-EOPENSTALE` if the cached information + wasn't quite current enough. Rather than restarting the lookup from + the top with `LOOKUP_REVAL` set, `lookup_open()` is called instead, + giving the filesystem a chance to resolve small inconsistencies. + If that doesn't work, only then is the lookup restarted from the top. + +3. An open with O_CREAT **does** follow a symlink in the final component, + unlike other creation system calls (like `mkdir`). So the sequence: + + > ln -s bar /tmp/foo + > echo hello > /tmp/foo + + will create a file called `/tmp/bar`. This is not permitted if + `O_EXCL` is set but otherwise is handled for an O_CREAT open much + like for a non-creating open: `should_follow_link()` returns `1`, and + so does `do_last()` so that `trailing_symlink()` gets called and the + open process continues on the symlink that was found. + +Updating the access time +------------------------ + +We previously said of RCU-walk that it would "take no locks, increment +no counts, leave no footprints." We have since seen that some +"footprints" can be needed when handling symlinks as a counted +reference (or even a memory allocation) may be needed. But these +footprints are best kept to a minimum. + +One other place where walking down a symlink can involve leaving +footprints in a way that doesn't affect directories is in updating access times. +In Unix (and Linux) every filesystem object has a "last accessed +time", or "`atime`". Passing through a directory to access a file +within is not considered to be an access for the purposes of +`atime`; only listing the contents of a directory can update its `atime`. +Symlinks are different it seems. Both reading a symlink (with `readlink()`) +and looking up a symlink on the way to some other destination can +update the atime on that symlink. + +[clearest statement]: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_08 + +It is not clear why this is the case; POSIX has little to say on the +subject. The [clearest statement] is that, if a particular implementation +updates a timestamp in a place not specified by POSIX, this must be +documented "except that any changes caused by pathname resolution need +not be documented". This seems to imply that POSIX doesn't really +care about access-time updates during pathname lookup. + +[Linux 1.3.87]: https://git.kernel.org/cgit/linux/kernel/git/history/history.git/diff/fs/ext2/symlink.c?id=f806c6db77b8eaa6e00dcfb6b567706feae8dbb8 + +An examination of history shows that prior to [Linux 1.3.87], the ext2 +filesystem, at least, didn't update atime when following a link. +Unfortunately we have no record of why that behavior was changed. + +In any case, access time must now be updated and that operation can be +quite complex. Trying to stay in RCU-walk while doing it is best +avoided. Fortunately it is often permitted to skip the `atime` +update. Because `atime` updates cause performance problems in various +areas, Linux supports the `relatime` mount option, which generally +limits the updates of `atime` to once per day on files that aren't +being changed (and symlinks never change once created). Even without +`relatime`, many filesystems record `atime` with a one-second +granularity, so only one update per second is required. + +It is easy to test if an `atime` update is needed while in RCU-walk +mode and, if it isn't, the update can be skipped and RCU-walk mode +continues. Only when an `atime` update is actually required does the +path walk drop down to REF-walk. All of this is handled in the +`get_link()` function. + +A few flags +----------- + +A suitable way to wrap up this tour of pathname walking is to list +the various flags that can be stored in the `nameidata` to guide the +lookup process. Many of these are only meaningful on the final +component, others reflect the current state of the pathname lookup. +And then there is `LOOKUP_EMPTY`, which doesn't fit conceptually with +the others. If this is not set, an empty pathname causes an error +very early on. If it is set, empty pathnames are not considered to be +an error. + +### Global state flags ### + +We have already met two global state flags: `LOOKUP_RCU` and +`LOOKUP_REVAL`. These select between one of three overall approaches +to lookup: RCU-walk, REF-walk, and REF-walk with forced revalidation. + +`LOOKUP_PARENT` indicates that the final component hasn't been reached +yet.

Others are only checked for when considering that final +component. + +`LOOKUP_AUTOMOUNT` ensures that, if the final component is an automount +point, then the mount is triggered. Some operations would trigger it +anyway, but operations like `stat()` deliberately don't. `statfs()` +needs to trigger the mount but otherwise behaves a lot like `stat()`, so +it sets `LOOKUP_AUTOMOUNT`, as does "`quotactl()`" and the handling of +"`mount --bind`". + +`LOOKUP_FOLLOW` has a similar function to `LOOKUP_AUTOMOUNT` but for +symlinks.

Introduction +~~~~~~~~~~~~~~~ + This module is intended to try to make the lives of input driver developers +easier by allowing them to test various serio devices (mainly the various +touchpads found on laptops) without having to have the physical device in front +of them. userio accomplishes this by allowing any privileged userspace program +to directly interact with the kernel's serio driver and control a virtual serio +port from there. + +2. Usage overview +~~~~~~~~~~~~~~~~~ + In order to interact with the userio kernel module, one simply opens the +/dev/userio character device in their applications. Commands are sent to the +kernel module by writing to the device, and any data received from the serio +driver is read as-is from the /dev/userio device. All of the structures and +macros you need to interact with the device are defined in and +. + +3. Command Structure +~~~~~~~~~~~~~~~~~~~~ + The struct used for sending commands to /dev/userio is as follows: + + struct userio_cmd { + __u8 type; + __u8 data; + }; + + "type" describes the type of command that is being sent. This can be any one +of the USERIO_CMD macros defined in . "data" is the argument +that goes along with the command. In the event that the command doesn't have an +argument, this field can be left untouched and will be ignored by the kernel. +Each command should be sent by writing the struct directly to the character +device. In the event that the command you send is invalid, an error will be +returned by the character device and a more descriptive error will be printed +to the kernel log. Only one command can be sent at a time, any additional data +written to the character device after the initial command will be ignored. + To close the virtual serio port, just close /dev/userio. + +4. Commands +~~~~~~~~~~~ + +4.1 USERIO_CMD_REGISTER +~~~~~~~~~~~~~~~~~~~~~~~ + Registers the port with the serio driver and begins transmitting data back and +forth.

A full SAT solver can be +desirable to enable more complex dependency mappings and / or queries, +for instance on possible use case for a SAT solver could be that of handling +the current known recursive dependency issues. It is not known if this would +address such issues but such evaluation is desirable. If support for a full SAT +solver proves too complex or that it cannot address recursive dependency issues +Kconfig should have at least clear and well defined semantics which also +addresses and documents limitations or requirements such as the ones dealing +with recursive dependencies. + +Further work on both of these areas is welcomed on Kconfig. We elaborate +on both of these in the next two subsections. + +Semantics of Kconfig +~~~~~~~~~~~~~~~~~~~~ + +The use of Kconfig is broad, Linux is now only one of Kconfig's users: +one study has completed a broad analysis of Kconfig use in 12 projects [0]. +Despite its widespread use, and although this document does a reasonable job +in documenting basic Kconfig syntax a more precise definition of Kconfig +semantics is welcomed. One project deduced Kconfig semantics through +the use of the xconfig configurator [1]. Work should be done to confirm if +the deduced semantics matches our intended Kconfig design goals. + +Having well defined semantics can be useful for tools for practical +evaluation of depenencies, for instance one such use known case was work to +express in boolean abstraction of the inferred semantics of Kconfig to +translate Kconfig logic into boolean formulas and run a SAT solver on this to +find dead code / features (always inactive), 114 dead features were found in +Linux using this methodology [1] (Section 8: Threats to validity). + +Confirming this could prove useful as Kconfig stands as one of the the leading +industrial variability modeling languages [1] [2]. Its study would help +evaluate practical uses of such languages, their use was only theoretical +and real world requirements were not well understood. As it stands though +only reverse engineering techniques have been used to deduce semantics from +variability modeling languages such as Kconfig [3]. + +[0] http://www.eng.uwaterloo.ca/~shshe/kconfig_semantics.pdf +[1] http://gsd.uwaterloo.ca/sites/default/files/vm-2013-berger.pdf +[2] http://gsd.uwaterloo.ca/sites/default/files/ase241-berger_0.pdf +[3] http://gsd.uwaterloo.ca/sites/default/files/icse2011.pdf + +Full SAT solver for Kconfig +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Although SAT solvers [0] haven't yet been used by Kconfig directly, as noted in +the previous subsection, work has been done however to express in boolean +abstraction the inferred semantics of Kconfig to translate Kconfig logic into +boolean formulas and run a SAT solver on it [1]. Another known related project +is CADOS [2] (former VAMOS [3]) and the tools, mainly undertaker [4], which has +been introduced first with [5]. The basic concept of undertaker is to exract +variability models from Kconfig, and put them together with a propositional +formula extracted from CPP #ifdefs and build-rules into a SAT solver in order +to find dead code, dead files, and dead symbols.

Define the model string table -and the table with struct snd_pci_quirk entries (zero-terminated), -and pass it to the function. The function checks the modelname given -as a module parameter, and PCI subsystem IDs. If the matching entry -is found, it returns the config field value. - -snd_hda_add_new_ctls() can be used to create and add control entries. -Pass the zero-terminated array of struct snd_kcontrol_new - -Macros HDA_CODEC_VOLUME(), HDA_CODEC_MUTE() and their variables can be -used for the entry of struct snd_kcontrol_new. - -The input MUX helper callbacks for such a control are provided, too: -snd_hda_input_mux_info() and snd_hda_input_mux_put().

STP (System Trace Protocol) is a trace +protocol multiplexing data from multiple trace sources, each one of +which is assigned a unique pair of master and channel. While some of +these masters and channels are statically allocated to certain +hardware trace sources, others are available to software. Software +trace sources are usually free to pick for themselves any +master/channel combination from this pool. + +On the receiving end of this STP stream (the decoder side), trace +sources can only be identified by master/channel combination, so in +order for the decoder to be able to make sense of the trace that +involves multiple trace sources, it needs to be able to map those +master/channel pairs to the trace sources that it understands. + +For instance, it is helpful to know that syslog messages come on +master 7 channel 15, while arbitrary user applications can use masters +48 to 63 and channels 0 to 127. + +To solve this mapping problem, stm class provides a policy management +mechanism via configfs, that allows defining rules that map string +identifiers to ranges of masters and channels. If these rules (policy) +are consistent with what decoder expects, it will be able to properly +process the trace data. + +This policy is a tree structure containing rules (policy_node) that +have a name (string identifier) and a range of masters and channels +associated with it, located in "stp-policy" subsystem directory in +configfs. The topmost directory's name (the policy) is formatted as +the STM device name to which this policy applies and and arbitrary +string identifier separated by a stop. From the examle above, a rule +may look like this: + +$ ls /config/stp-policy/dummy_stm.my-policy/user +channels masters +$ cat /config/stp-policy/dummy_stm.my-policy/user/masters +48 63 +$ cat /config/stp-policy/dummy_stm.my-policy/user/channels +0 127 + +which means that the master allocation pool for this rule consists of +masters 48 through 63 and channel allocation pool has channels 0 +through 127 in it. Now, any producer (trace source) identifying itself +with "user" identification string will be allocated a master and +channel from within these ranges. + +These rules can be nested, for example, one can define a rule "dummy" +under "user" directory from the example above and this new rule will +be used for trace sources with the id string of "user/dummy". + +Trace sources have to open the stm class device's node and write their +trace data into its file descriptor. In order to identify themselves +to the policy, they need to do a STP_POLICY_ID_SET ioctl on this file +descriptor providing their id string. Otherwise, they will be +automatically allocated a master/channel pair upon first write to this +file descriptor according to the "default" rule of the policy, if such +exists. + +Some STM devices may allow direct mapping of the channel mmio regions +to userspace for zero-copy writing. One mappable page (in terms of +mmu) will usually contain multiple channels' mmios, so the user will +need to allocate that many channels to themselves (via the +aforementioned ioctl() call) to be able to do this. That is, if your +stm device's channel mmio region is 64 bytes and hardware page size is +4096 bytes, after a successful STP_POLICY_ID_SET ioctl() call with +width==64, you should be able to mmap() one page on this file +descriptor and obtain direct access to an mmio region for 64 channels. + +For kernel-based trace sources, there is "stm_source" device +class.

The code is famously known as the VGIC. + +Some of these virtual interrupts, however, correspond to physical +interrupts from real physical devices. One example could be the +architected timer, which itself supports virtualization, and therefore +lets a guest OS program the hardware device directly to raise an +interrupt at some point in time. When such an interrupt is raised, the +host OS initially handles the interrupt and must somehow signal this +event as a virtual interrupt to the guest. Another example could be a +passthrough device, where the physical interrupts are initially handled +by the host, but the device driver for the device lives in the guest OS +and KVM must therefore somehow inject a virtual interrupt on behalf of +the physical one to the guest OS. + +These virtual interrupts corresponding to a physical interrupt on the +host are called forwarded physical interrupts, but are also sometimes +referred to as 'virtualized physical interrupts' and 'mapped interrupts'. + +Forwarded physical interrupts are handled slightly differently compared +to virtual interrupts generated purely by a software emulated device. + + +The HW bit +---------- +Virtual interrupts are signalled to the guest by programming the List +Registers (LRs) on the GIC before running a VCPU. The LR is programmed +with the virtual IRQ number and the state of the interrupt (Pending, +Active, or Pending+Active). When the guest ACKs and EOIs a virtual +interrupt, the LR state moves from Pending to Active, and finally to +inactive. + +The LRs include an extra bit, called the HW bit. When this bit is set, +KVM must also program an additional field in the LR, the physical IRQ +number, to link the virtual with the physical IRQ. + +When the HW bit is set, KVM must EITHER set the Pending OR the Active +bit, never both at the same time. + +Setting the HW bit causes the hardware to deactivate the physical +interrupt on the physical distributor when the guest deactivates the +corresponding virtual interrupt. + + +Forwarded Physical Interrupts Life Cycle +---------------------------------------- + +The state of forwarded physical interrupts is managed in the following way: + + - The physical interrupt is acked by the host, and becomes active on + the physical distributor (*). + - KVM sets the LR.Pending bit, because this is the only way the GICV + interface is going to present it to the guest. + - LR.Pending will stay set as long as the guest has not acked the interrupt. + - LR.Pending transitions to LR.Active on the guest read of the IAR, as + expected. + - On guest EOI, the *physical distributor* active bit gets cleared, + but the LR.Active is left untouched (set). + - KVM clears the LR on VM exits when the physical distributor + active state has been cleared. + +(*): The host handling is slightly more complicated. For some forwarded +interrupts (shared), KVM directly sets the active state on the physical +distributor before entering the guest, because the interrupt is never actually +handled on the host (see details on the timer as an example below). For other +forwarded interrupts (non-shared) the host does not deactivate the interrupt +when the host ISR completes, but leaves the interrupt active until the guest +deactivates it. Leaving the interrupt active is allowed, because Linux +configures the physical GIC with EOIMode=1, which causes EOI operations to +perform a priority drop allowing the GIC to receive other interrupts of the +default priority. + + +Forwarded Edge and Level Triggered PPIs and SPIs +------------------------------------------------ +Forwarded physical interrupts injected should always be active on the +physical distributor when injected to a guest. + +Level-triggered interrupts will keep the interrupt line to the GIC +asserted, typically until the guest programs the device to deassert the +line. This means that the interrupt will remain pending on the physical +distributor until the guest has reprogrammed the device. Since we +always run the VM with interrupts enabled on the CPU, a pending +interrupt will exit the guest as soon as we switch into the guest, +preventing the guest from ever making progress as the process repeats +over and over. Therefore, the active state on the physical distributor +must be set when entering the guest, preventing the GIC from forwarding +the pending interrupt to the CPU. As soon as the guest deactivates the +interrupt, the physical line is sampled by the hardware again and the host +takes a new interrupt if and only if the physical line is still asserted. + +Edge-triggered interrupts do not exhibit the same problem with +preventing guest execution that level-triggered interrupts do. One +option is to not use HW bit at all, and inject edge-triggered interrupts +from a physical device as pure virtual interrupts. But that would +potentially slow down handling of the interrupt in the guest, because a +physical interrupt occurring in the middle of the guest ISR would +preempt the guest for the host to handle the interrupt. Additionally, +if you configure the system to handle interrupts on a separate physical +core from that running your VCPU, you still have to interrupt the VCPU +to queue the pending state onto the LR, even though the guest won't use +this information until the guest ISR completes. Therefore, the HW +bit should always be set for forwarded edge-triggered interrupts. With +the HW bit set, the virtual interrupt is injected and additional +physical interrupts occurring before the guest deactivates the interrupt +simply mark the state on the physical distributor as Pending+Active. As +soon as the guest deactivates the interrupt, the host takes another +interrupt if and only if there was a physical interrupt between injecting +the forwarded interrupt to the guest and the guest deactivating the +interrupt. + +Consequently, whenever we schedule a VCPU with one or more LRs with the +HW bit set, the interrupt must also be active on the physical +distributor. + + +Forwarded LPIs +-------------- +LPIs, introduced in GICv3, are always edge-triggered and do not have an +active state. They become pending when a device signal them, and as +soon as they are acked by the CPU, they are inactive again. + +It therefore doesn't make sense, and is not supported, to set the HW bit +for physical LPIs that are forwarded to a VM as virtual interrupts, +typically virtual SPIs. + +For LPIs, there is no other choice than to preempt the VCPU thread if +necessary, and queue the pending state onto the LR. + + +Putting It Together: The Architected Timer +------------------------------------------ +The architected timer is a device that signals interrupts with level +triggered semantics. The timer hardware is directly accessed by VCPUs +which program the timer to fire at some point in time. Each VCPU on a +system programs the timer to fire at different times, and therefore the +hardware is multiplexed between multiple VCPUs. This is implemented by +context-switching the timer state along with each VCPU thread. + +However, this means that a scenario like the following is entirely +possible, and in fact, typical: + +1. KVM runs the VCPU +2. The guest programs the time to fire in T+100 +3. The guest is idle and calls WFI (wait-for-interrupts) +4. The hardware traps to the host +5.

KVM runs the VCPU + +Notice that KVM injects a forwarded physical interrupt in step 11 without +the corresponding interrupt having actually fired on the host. That is +exactly why we mark the timer interrupt as active in step 10, because +the active state on the physical distributor is part of the state +belonging to the timer hardware, which is context-switched along with +the VCPU thread. + +If the guest does not idle because it is busy, the flow looks like this +instead: + +1. KVM runs the VCPU +2. The guest programs the time to fire in T+100 +4. At T+100 the timer fires and a physical IRQ causes the VM to exit + (note that this initially only traps to EL2 and does not run the host ISR + until KVM has returned to the host). +5.

There's a root + * oscillator running at 19.2Mhz. After the oscillator there are 5 + * PLLs, roughly divided as "camera", "ARM", "core", "DSI displays", + * and "HDMI displays". Those 5 PLLs each can divide their output to + * produce up to 4 channels. Finally, there is the level of clocks to + * be consumed by other hardware components (like "H264" or "HDMI + * state machine"), which divide off of some subset of the PLL + * channels. + * + * All of the clocks in the tree are exposed in the DT, because the DT + * may want to make assignments of the final layer of clocks to the + * PLL channels, and some components of the hardware will actually + * skip layers of the tree (for example, the pixel clock comes + * directly from the PLLH PIX channel without using a CM_*CTL clock + * generator). + */ + +#include +#include +#include +#include

On Linux this is + * supported with DRI PRIME. + * + * Hybrid graphics started to appear in the late Naughties and were initially + * all muxed. Newer laptops moved to a muxless architecture for cost reasons. + * A notable exception is the MacBook Pro which continues to use a mux. + * Muxes come with varying capabilities: Some switch only the panel, others + * can also switch external displays. Some switch all display pins at once + * while others can switch just the DDC lines. (To allow EDID probing + * for the inactive GPU.) Also, muxes are often used to cut power to the + * discrete GPU while it is not used. + * + * DRM drivers register GPUs with vga_switcheroo, these are heretoforth called + * clients. The mux is called the handler. Muxless machines also register a + * handler to control the power state of the discrete GPU, its ->switchto + * callback is a no-op for obvious reasons. The discrete GPU is often equipped + * with an HDA controller for the HDMI/DP audio signal, this will also + * register as a client so that vga_switcheroo can take care of the correct + * suspend/resume order when changing the discrete GPU's power state. In total + * there can thus be up to three clients: Two vga clients (GPUs) and one audio + * client (on the discrete GPU). The code is mostly prepared to support + * machines with more than two GPUs should they become available. + * The GPU to which the outputs are currently switched is called the + * active client in vga_switcheroo parlance.

SCIF is used to (a) Send a shutdown command to the card (b) + * receive a shutdown status back from the card upon completion of shutdown and + * (c) receive periodic heartbeat messages from the card used to deduce if the + * card has crashed. + * + * A COSM server consisting of a SCIF listening endpoint waits for incoming + * connections from the card.

A new + * work-item starts each time the card boots and is alive till the card (a) + * shuts down (b) is reset (c) crashes (d) cosm_client driver on the card is + * unloaded. + * + * From the point of view of COSM interactions with SCIF during card + * shutdown, reset and crash are as follows: + * + * Card shutdown + * ------------- + * 1. COSM client on the card invokes orderly_poweroff() in response to SHUTDOWN + * message from the host. + * 2. Card driver shutdown callback invokes scif_unregister_device(..) resulting + * in scif_remove(..) getting called on the card + * 3. scif_remove -> scif_stop -> scif_handle_remove_node -> + * scif_peer_unregister_device -> device_unregister for the host peer device + * 4. During device_unregister remove(..) method of cosm_client is invoked which + * closes the COSM SCIF endpoint on the card. This results in a SCIF_DISCNCT + * message being sent to host SCIF. SCIF_DISCNCT message processing on the + * host SCIF sets the host COSM SCIF endpoint state to DISCONNECTED and wakes + * up the host COSM thread blocked in scif_poll(..) resulting in + * scif_poll(..) returning POLLHUP. + * 5. On the card, scif_peer_release_dev is next called which results in an + * SCIF_EXIT message being sent to the host and after receiving the + * SCIF_EXIT_ACK from the host the peer device teardown on the card is + * complete. + * 6. As part of the SCIF_EXIT message processing on the host, host sends a + * SCIF_REMOVE_NODE to itself corresponding to the card being removed. This + * starts a similar SCIF peer device teardown sequence on the host + * corresponding to the card being shut down. + * + * Card reset + * ---------- + * The case of interest here is when the card has not been previously shut down + * since most of the steps below are skipped in that case: + + * 1. cosm_stop(..) invokes hw_ops->stop(..) method of the base PCIe driver + * which unregisters the SCIF HW device resulting in scif_remove(..) being + * called on the host. + * 2. scif_remove(..) calls scif_disconnect_node(..) which results in a + * SCIF_EXIT message being sent to the card. + * 3. The card executes scif_stop() as part of SCIF_EXIT message + * processing. This results in the COSM endpoint on the card being closed and + * the SCIF host peer device on the card getting unregistered similar to + * steps 3, 4 and 5 for the card shutdown case above. scif_poll(..) on the + * host returns POLLHUP as a result. + * 4. On the host, card peer device unregister and SCIF HW remove(..) also + * subsequently complete. + * + * Card crash + * ---------- + * If a reset is issued after the card has crashed, there is no SCIF_DISCNT + * message from the card which would result in scif_poll(..) returning + * POLLHUP.
