+In addition, you can use GDB to figure out the exact file and line
+number of the OOPS from the vmlinux file. If you have
+CONFIG_DEBUG_INFO enabled, you can simply copy the EIP value from the
+OOPS:
+
+ EIP: 0060:[<c021e50e>] Not tainted VLI
+
+And use GDB to translate that to human-readable form:
+
+ gdb vmlinux
+ (gdb) l *0xc021e50e
+
+If you don't have CONFIG_DEBUG_INFO enabled, you use the function

+

Short users guide for SLUB
--------------------------
-First of all slub should transparently replace SLAB. If you enable
-SLUB then everything should work the same (Note the word "should".
-There is likely not much value in that word at this point).

The basic philosophy of SLUB is very different from SLAB. SLAB

+slab caches. SLUB always includes full debugging but it is off by default.
SLUB can enable debugging only for selected slabs in order to avoid
an impact on overall system performance which may make a bug more
difficult to find.
Careful with tracing: It may spew out lots of information and never stop if
used on the wrong slab.
-SLAB Merging
+Slab merging
------------
-If no debugging is specified then SLUB may merge similar slabs together
+If no debug options are specified then SLUB may merge similar slabs together
in order to reduce overhead and increase cache hotness of objects.
slabinfo -a displays which slabs were merged together.
+Slab validation
+---------------
+
+SLUB can validate all object if the kernel was booted with slub_debug. In
+order to do so you must have the slabinfo tool. Then you can do
+
+slabinfo -v
+
+which will test all objects. Output will be generated to the syslog.
+
+This also works in a more limited way if boot was without slab debug.
+In that case slabinfo -v simply tests all reachable objects. Usually
+these are in the cpu slabs and the partial slabs. Full slabs are not
+tracked by SLUB in a non debug situation.

Getting more performance
------------------------
governed by the order of the allocation for each slab. The allocations
can be influenced by kernel parameters:
-slub_min_objects=x (default 8)
+slub_min_objects=x (default 4)
slub_min_order=x (default 0)
-slub_max_order=x (default 4)
+slub_max_order=x (default 1)
slub_min_objects allows to specify how many objects must at least fit
into one slab in order for the allocation order to be acceptable.

+@@@ SLUB kmalloc-8: Restoring redzone (0xcc) from 0xc90f6d28-0xc90f6d2b
+
+
+
+If SLUB encounters a corrupted object then it will perform the following
+actions:
+
+1. Isolation and report of the issue
+
+This will be a message in the system log starting with
+
+*** SLUB <slab cache affected>: <What went wrong>@<object address>
+offset=<offset of object into slab> flags=<slabflags>
+inuse=<objects in use in this slab> freelist=<first free object in slab>
+
+2. Report on how the problem was dealt with in order to ensure the continued
+operation of the system.
+
+These are messages in the system log beginning with
+
+@@@ SLUB <slab cache affected>: <corrective action taken>
+
+
+In the above sample SLUB found that the Redzone of an active object has
+been overwritten. Here a string of 8 characters was written into a slab that
+has the length of 8 characters. However, a 8 character string needs a
+terminating 0. That zero has overwritten the first byte of the Redzone field.
+After reporting the details of the issue encountered the @@@ SLUB message
+tell us that SLUB has restored the redzone to its proper value and then
+system operations continue.
+
+Various types of lines can follow the @@@ SLUB line:
+
+Bytes b4 <address> : <bytes>
+ Show a few bytes before the object where the problem was detected.
+ Can be useful if the corruption does not stop with the start of the
+ object.
+
+Object <address> : <bytes>
+ The bytes of the object. If the object is inactive then the bytes
+ typically contain poisoning values. Any non-poison value shows a
+ corruption by a write after free.
+
+Redzone <address> : <bytes>
+ The redzone following the object. The redzone is used to detect
+ writes after the object. All bytes should always have the same
+ value. If there is any deviation then it is due to a write after
+ the object boundary.
+
+Freepointer
+ The pointer to the next free object in the slab. May become
+ corrupted if overwriting continues after the red zone.
+
+Last alloc:
+Last free:
+ Shows the address from which the object was allocated/freed last.
+ We note the pid, the time and the CPU that did so. This is usually
+ the most useful information to figure out where things went wrong.
+ Here get_modalias() did an kmalloc(8) instead of a kmalloc(9).
+
+Filler <address> : <bytes>
+ Unused data to fill up the space in order to get the next object
+ properly aligned. In the debug case we make sure that there are
+ at least 4 bytes of filler. This allow for the detection of writes
+ before the object.
+
+Following the filler will be a stackdump. That stackdump describes the
+location where the error was detected. The cause of the corruption is more
+likely to be found by looking at the information about the last alloc / free.

-where they do strange things compared to the other drivers.
-
-acquirewdt.c -- Acquire Single Board Computer
-
- This driver has a hardcoded timeout of 1 minute
-
- Supports CONFIG_WATCHDOG_NOWAYOUT
-
- GETSUPPORT returns KEEPALIVEPING. GETSTATUS will return 1 if
- the device is open, 0 if not. [FIXME -- isn't this rather
- silly? To be able to use the ioctl, the device must be open
- and so GETSTATUS will always return 1].
-
-advantechwdt.c -- Advantech Single Board Computer

-booke_wdt.c -- PowerPC BookE Watchdog Timer
-
- Timeout default varies according to frequency, supports
- SETTIMEOUT
-
- Watchdog cannot be turned off, CONFIG_WATCHDOG_NOWAYOUT
- does not make sense
-
- GETSUPPORT returns the watchdog_info struct, and
- GETSTATUS returns the supported options. GETBOOTSTATUS
- returns a 1 if the last reset was caused by the
- watchdog and a 0 otherwise. This watchdog cannot be
- disabled once it has been started. The wdt_period kernel
- parameter selects which bit of the time base changing
- from 0->1 will trigger the watchdog exception. Changing
- the timeout from the ioctl calls will change the
- wdt_period as defined above. Finally if you would like to
- replace the default Watchdog Handler you can implement the
- WatchdogHandler() function in your own code.

- using the SETTIMEOUT ioctl.

- Watchdog Timer Interfaces For The Linux Operating System

- Alan Cox <alan@lxorguk.ukuu.org.uk>
-
- Custom Linux Driver And Program Development
-
-
-The following watchdog drivers are currently implemented:
-
- ICS WDT501-P
- ICS WDT501-P (no fan tachometer)
- ICS WDT500-P
- Software Only
- SA1100 Internal Watchdog
- Berkshire Products PC Watchdog Revision A & C (by Ken Hollis)
-
-
-All six interfaces provide /dev/watchdog, which when open must be written
-to within a timeout or the machine will reboot. Each write delays the reboot
-time another timeout. In the case of the software watchdog the ability to
-reboot will depend on the state of the machines and interrupts. The hardware
-boards physically pull the machine down off their own onboard timers and
-will reboot from almost anything.
-
-A second temperature monitoring interface is available on the WDT501P cards
-and some Berkshire cards. This provides /dev/temperature. This is the machine
-internal temperature in degrees Fahrenheit. Each read returns a single byte
-giving the temperature.
-
-The third interface logs kernel messages on additional alert events.
-
-Both software and hardware watchdog drivers are available in the standard
-kernel. If you are using the software watchdog, you probably also want
-to use "panic=60" as a boot argument as well.
-
-The wdt card cannot be safely probed for. Instead you need to pass
-wdt=ioaddr,irq as a boot parameter - eg "wdt=0x240,11".
-
-The SA1100 watchdog module can be configured with the "sa1100_margin"
-commandline argument which specifies timeout value in seconds.
-
-The i810 TCO watchdog modules can be configured with the "i810_margin"
-commandline argument which specifies the counter initial value. The counter
-is decremented every 0.6 seconds and default to 50 (30 seconds). Values can
-range between 3 and 63.
-
-The i810 TCO watchdog driver also implements the WDIOC_GETSTATUS and
-WDIOC_GETBOOTSTATUS ioctl()s. WDIOC_GETSTATUS returns the actual counter value
-and WDIOC_GETBOOTSTATUS returns the value of TCO2 Status Register (see Intel's
-documentation for the 82801AA and 82801AB datasheet).
