vm: fix move_vma() memory accounting being off

Commit 408579cd627a ("mm: Update do_vmi_align_munmap() return
semantics") seems to have updated one of the callers of do_vmi_munmap()
incorrectly: it used to check for the error case (which didn't
change: negative means error).

That commit changed the check to the success case (which did change:
before that commit, 0 was success, and 1 was "success and lock
downgraded".  After the change, it's always 0 for success, and the lock
will have been released if requested).

This didn't change any actual VM behavior _except_ for memory accounting
when 'VM_ACCOUNT' was set on the vma.  Which made the wrong return value
test fairly subtle, since everything continues to work.

Or rather - it continues to work but the "Committed memory" accounting
goes all wonky (Committed_AS value in /proc/meminfo), and depending on
settings that then causes problems much much later as the VM relies on
bogus statistics for its heuristics.

Revert that one line of the change back to the original logic.

ata: libata-core: fetch sense data for successful commands iff CDL enabled

Currently, we fetch sense data for a _successful_ command if either:
1) Command was NCQ and ATA_DFLAG_CDL_ENABLED flag set (flag
   ATA_DFLAG_CDL_ENABLED will only be set if the Successful NCQ command
   sense data supported bit is set); or
2) Command was non-NCQ and regular sense data reporting is enabled.

This means that case 2) will trigger for a non-NCQ command which has
ATA_SENSE bit set, regardless if CDL is enabled or not.

This decision was by design. If the device reports that it has sense data
available, it makes sense to fetch that sense data, since the sk/asc/ascq
could be important information regardless if CDL is enabled or not.

However, the fetching of sense data for a successful command is done via
ATA EH. Considering how intricate the ATA EH is, we really do not want to
invoke ATA EH unless absolutely needed.

Before commit 18bd7718b5c4 ("scsi: ata: libata: Handle completion of CDL
commands using policy 0xD") we never fetched sense data for successful
commands.

In order to not invoke the ATA EH unless absolutely necessary, even if the
device claims support for sense data reporting, only fetch sense data for
successful (NCQ and non-NCQ commands) commands that are using CDL.

[Damien] Modified the check to test the qc flag ATA_QCFLAG_HAS_CDL
instead of the device support for CDL, which is implied for commands
using CDL.

ata: libata-eh: do not thaw the port twice in ata_eh_reset()

commit 1e641060c4b5 ("libata: clear eh_info on reset completion") added
a workaround that broke the retry mechanism in ATA EH.

Tejun himself suggested to remove this workaround when it was identified
to cause additional problems:
https://lore.kernel.org/linux-ide/20110426135027.GI878@htj.dyndns.org/

He even said:
"Hmm... it seems I wasn't thinking straight when I added that work around."
https://lore.kernel.org/linux-ide/20110426155229.GM878@htj.dyndns.org/

While removing the workaround solved the issue, however, the workaround was
kept to avoid "spurious hotplug events during reset", and instead another
workaround was added on top of the existing workaround in commit
8c56cacc724c ("libata: fix unexpectedly frozen port after ata_eh_reset()").

Because these IRQs happened when the port was frozen, we know that they
were actually a side effect of PxIS and IS.IPS(x) not being cleared before
the COMRESET. This is now done in commit 94152042eaa9 ("ata: libahci: clear
pending interrupt status"), so these workarounds can now be removed.

Since commit 1e641060c4b5 ("libata: clear eh_info on reset completion") has
now been reverted, the ATA EH retry mechanism is functional again, so there
is once again no need to thaw the port more than once in ata_eh_reset().

This reverts "the workaround on top of the workaround" introduced in commit
8c56cacc724c ("libata: fix unexpectedly frozen port after ata_eh_reset()").

ata: libata-eh: do not clear ATA_PFLAG_EH_PENDING in ata_eh_reset()

ata_scsi_port_error_handler() starts off by clearing ATA_PFLAG_EH_PENDING,
before calling ap->ops->error_handler() (without holding the ap->lock).

If an error IRQ is received while ap->ops->error_handler() is running,
the irq handler will set ATA_PFLAG_EH_PENDING.

Once ap->ops->error_handler() returns, ata_scsi_port_error_handler()
checks if ATA_PFLAG_EH_PENDING is set, and if it is, another iteration
of ATA EH is performed.

The problem is that ATA_PFLAG_EH_PENDING is not only cleared by
ata_scsi_port_error_handler(), it is also cleared by ata_eh_reset().

ata_eh_reset() is called by ap->ops->error_handler(). This additional
clearing done by ata_eh_reset() breaks the whole retry logic in
ata_scsi_port_error_handler(). Thus, if an error IRQ is received while
ap->ops->error_handler() is running, the port will currently remain
frozen and will never get re-enabled.

The additional clearing in ata_eh_reset() was introduced in commit
1e641060c4b5 ("libata: clear eh_info on reset completion").

Looking at the original error report:
https://marc.info/?l=linux-ide&m=124765325828495&w=2

We can see the following happening:
[    1.074659] ata3: XXX port freeze
[    1.074700] ata3: XXX hardresetting link, stopping engine
[    1.074746] ata3: XXX flipping SControl

[    1.420234] ata3: SATA link up 3.0 Gbps (SStatus 123 SControl 300)

We are not supposed to be able to receive an error IRQ while the port is
frozen (PxIE is set to 0, i.e. all IRQs for the port are disabled).

AHCI 1.3.1 section 10.7.1.1 First Tier (IS Register) states:
"Each bit location can be thought of as reporting a '1' if the virtual
"interrupt line" for that port is indicating it wishes to generate an
interrupt. That is, if a port has one or more interrupt status bit set,
and the enables for those status bits are set, then this bit shall be set."

Additionally, AHCI state P:ComInit clearly shows that the state machine
will only jump to P:ComInitSetIS (which sets IS.IPS(x) to '1'), if PxIE.PCE
is set to '1'. In our case, PxIE is set to 0, so IS.IPS(x) won't get set.

So IS.IPS(x) only gets set if PxIS and PxIE is set.

AHCI 1.3.1 section 10.7.1.1 First Tier (IS Register) also states:
"The bits in this register are read/write clear. It is set by the level of
the virtual interrupt line being a set, and cleared by a write of '1' from
the software."

So if IS.IPS(x) is set, you need to explicitly clear it by writing a 1 to
IS.IPS(x) for that port.

Since PxIE is cleared, the only way to get an interrupt while the port is
frozen, is if IS.IPS(x) is set, and the only way IS.IPS(x) can be set when
the port is frozen, is if it was set before the port was frozen.

However, since commit 737dd811a3db ("ata: libahci: clear pending interrupt
status"), we clear both PxIS and IS.IPS(x) after freezing the port, but
before the COMRESET, so the problem that commit 1e641060c4b5 ("libata:
clear eh_info on reset completion") fixed can no longer happen.

Thus, revert commit 1e641060c4b5 ("libata: clear eh_info on reset
completion"), so that the retry logic in ata_scsi_port_error_handler()
works once again. (The retry logic is still needed, since we can still
get an error IRQ _after_ the port has been thawed, but before
ata_scsi_port_error_handler() takes the ap->lock in order to check
if ATA_PFLAG_EH_PENDING is set.)

8 months agodm: don't attempt to queue IO under RCU protection
Jens Axboe [Fri, 15 Sep 2023 19:14:23 +0000 (13:14 -0600)]
dm: don't attempt to queue IO under RCU protection

dm looks up the table for IO based on the request type, with an
assumption that if the request is marked REQ_NOWAIT, it's fine to
attempt to submit that IO while under RCU read lock protection. This
is not OK, as REQ_NOWAIT just means that we should not be sleeping
waiting on other IO, it does not mean that we can't potentially
schedule.

A simple test case demonstrates this quite nicely:

int main(int argc, char *argv[])
{
        struct iovec iov;
        int fd;

        fd = open("/dev/dm-0", O_RDONLY | O_DIRECT);
        posix_memalign(&iov.iov_base, 4096, 4096);
        iov.iov_len = 4096;
        preadv2(fd, &iov, 1, 0, RWF_NOWAIT);
        return 0;
}

which will instantly spew:

Szuying Chen [Thu, 7 Sep 2023 08:17:10 +0000 (16:17 +0800)]
ata: libahci: clear pending interrupt status

When a CRC error occurs, the HBA asserts an interrupt to indicate an
interface fatal error (PxIS.IFS). The ISR clears PxIE and PxIS, then
does error recovery. If the adapter receives another SDB FIS
with an error (PxIS.TFES) from the device before the start of the EH
recovery process, the interrupt signaling the new SDB cannot be
serviced as PxIE was cleared already. This in turn results in the HBA
inability to issue any command during the error recovery process after
setting PxCMD.ST to 1 because PxIS.TFES is still set.

According to AHCI 1.3.1 specifications section 6.2.2, fatal errors
notified by setting PxIS.HBFS, PxIS.HBDS, PxIS.IFS or PxIS.TFES will
cause the HBA to enter the ERR:Fatal state. In this state, the HBA
shall not issue any new commands.

To avoid this situation, introduce the function
ahci_port_clear_pending_irq() to clear pending interrupts before
executing a COMRESET. This follows the AHCI 1.3.1 - section 6.2.2.2
specification.

nvme: avoid bogus CRTO values

Some devices are reporting controller ready mode support, but return 0
for CRTO. These devices require a much higher time to ready than that,
so they are failing to initialize after the driver starter preferring
that value over CAP.TO.

The spec requires that CAP.TO match the appropritate CRTO value, or be
set to 0xff if CRTO is larger than that. This means that CAP.TO can be
used to validate if CRTO is reliable, and provides an appropriate
fallback for setting the timeout value if not. Use whichever is larger.

To address this, helpers like ext4_rec_len_{from,to}_disk has already
been introduced to complete the conversion between the encoded and the
plain form of rec_len.

So fix this one by using the helper, and all the other in this file too.

ext4: do not let fstrim block system suspend

Len Brown has reported that system suspend sometimes fail due to
inability to freeze a task working in ext4_trim_fs() for one minute.
Trimming a large filesystem on a disk that slowly processes discard
requests can indeed take a long time. Since discard is just an advisory
call, it is perfectly fine to interrupt it at any time and the return
number of discarded blocks until that moment. Do that when we detect the
task is being frozen.

There's a race condition in the multipath target when retrieve_deps
races with multipath_message calling dm_get_device and dm_put_device.
retrieve_deps walks the list of open devices without holding any lock

running. The end result may be memory corruption or use-after-free

See this description of a UAF with multipath_message():

Fix this bug by introducing a new rw semaphore "devices_lock". We grab

In short, the sequence leading to the UAF is as follows:

Code allocates a struct device as a kunit-managed resource.
Code allocates a drm driver as a kunit-managed resource.
Code allocates a drm device as a device-managed resource.

EXIT:
Kunit resource cleanup frees the drm driver
Kunit resource cleanup puts the struct device, which starts a

device-managed cleanup calls drm_dev_put()

kcm: Fix error handling for SOCK_DGRAM in kcm_sendmsg().

syzkaller found a memory leak in kcm_sendmsg(), and commit c821a88bd720
("kcm: Fix memory leak in error path of kcm_sendmsg()") suppressed it by
updating kcm_tx_msg(head)->last_skb if partial data is copied so that the
following sendmsg() will resume from the skb.

However, we cannot know how many bytes were copied when we get the error.
Thus, we could mess up the MSG_MORE queue.

When kcm_sendmsg() fails for SOCK_DGRAM, we should purge the queue as we
do so for UDP by udp_flush_pending_frames().

Even without this change, when the error occurred, the following sendmsg()
resumed from a wrong skb and the queue was messed up.  However, we have
yet to get such a report, and only syzkaller stumbled on it.  So, this
can be changed safely.

Note this does not change SOCK_SEQPACKET behaviour.

scsi: lpfc: Prevent use-after-free during rmmod with mapped NVMe rports

During rmmod, when dev_loss_tmo callback is called, an ndlp kref count is
decremented twice.  Once for SCSI transport registration and second to
remove the initial node allocation kref.  If there is also an NVMe
transport registration, another reference count decrement is expected in
lpfc_nvme_unregister_port().

Race conditions between the NVMe transport remoteport_delete and
dev_loss_tmo callbacks sometimes results in premature ndlp object release
resulting in use-after-free issues.

Fix by not dropping the ndlp object in dev_loss_tmo callback with an
outstanding NVMe transport registration.  Inversely, mark the final
NLP_DROPPED flag in lpfc_nvme_unregister_port when rmmod flag is set.

that igb_enable_sriov()'s call to pci_enable_sriov() is failing, because
dev->is_physfn is 0 on 82580.

Prior to commit 50f303496d92 ("igb: Enable SR-IOV after reinit"),
igb_enable_sriov() jumped into the "err_out" cleanup branch.  After this

So the cleanup didn't take place, and the incorrect VF setup in the

ixgbe: fix timestamp configuration code

The commit in fixes introduced flags to control the status of hardware
configuration while processing packets. At the same time another structure
is used to provide configuration of timestamper to user-space applications.
The way it was coded makes this structures go out of sync easily. The
repro is easy for 82599 chips:

[root@hostname ~]# hwstamp_ctl -i eth0 -r 12 -t 1
current settings:
tx_type 0
rx_filter 0
new settings:
tx_type 1
rx_filter 12

The eth0 device is properly configured to timestamp any PTPv2 events.

[root@hostname ~]# hwstamp_ctl -i eth0 -r 1 -t 1
current settings:
tx_type 1
rx_filter 12
SIOCSHWTSTAMP failed: Numerical result out of range
The requested time stamping mode is not supported by the hardware.

The error is properly returned because HW doesn't support all packets
timestamping. But the adapter->flags is cleared of timestamp flags
even though no HW configuration was done. From that point no RX timestamps
are received by user-space application. But configuration shows good
values:

[root@hostname ~]# hwstamp_ctl -i eth0
current settings:
tx_type 1
rx_filter 12

Fix the issue by applying new flags only when the HW was actually
configured.

This reverts commit b5c75b68b7ded84d4c82118974ce3975a4dcaa74.

The commit makes it impossible to select configuration options that
depend on COMEDI_8254, COMEDI_DAS08, COMEDI_NI_LABPC, or
COMEDI_AMPLC_DIO200 options due to changing 'select' directives to
'depends on' directives and there being no other way to select those
codependent configuration options.

8 months agoNFSD: fix possible oops when nfsd/pool_stats is closed.

NFSD: fix possible oops when nfsd/pool_stats is closed.

If /proc/fs/nfsd/pool_stats is open when the last nfsd thread exits, then
when the file is closed a NULL pointer is dereferenced.
This is because nfsd_pool_stats_release() assumes that the
pointer to the svc_serv cannot become NULL while a reference is held.

This used to be the case but a recent patch split nfsd_last_thread() out
from nfsd_put(), and clearing the pointer is done in nfsd_last_thread().

This is easily reproduced by running
   rpc.nfsd 8 ; ( rpc.nfsd 0;true) < /proc/fs/nfsd/pool_stats

Fortunately nfsd_pool_stats_release() has easy access to the svc_serv
pointer, and so can call svc_put() on it directly.
