      cifs: do not fail __smb_send_rqst if non-fatal signals are pending · 214a5ea0
      Ronnie Sahlberg authored 
      RHBZ 1848178

The original intent of returning an error in this function
in the patch:
  "CIFS: Mask off signals when sending SMB packets"
was to avoid interrupting packet send in the middle of
sending the data (and thus breaking an SMB connection),
but we also don't want to fail the request for non-fatal
signals even before we have had a chance to try to
send it (the reported problem could be reproduced e.g.
by exiting a child process when the parent process was in
the midst of calling futimens to update a file's timestamps).

In addition, since the signal may remain pending when we enter the
sending loop, we may end up not sending the whole packet before
TCP buffers become full. In this case the code returns -EINTR
but what we need here is to return -ERESTARTSYS instead to
allow system calls to be restarted.

Fixes: b30c74c7 ("CIFS: Mask off signals when sending SMB packets")

Pull device mapper fixes from Mike Snitzer:

 - Fix DM integrity crash if "recalculate" used without "internal_hash"

 - Fix DM integrity "recalculate" support to prevent recalculating
   checksums if we use internal_hash or journal_hash with a key (e.g.
   HMAC). Use of crypto as a means to prevent malicious corruption
   requires further changes and was never a design goal for
   dm-integrity's primary usecase of detecting accidental corruption.

 - Fix a benign dm-crypt copy-and-paste bug introduced as part of a fix
   that was merged for 5.11-rc4.

 - Fix DM core's dm_get_device() to avoid filesystem lookup to get block
   device (if possible).

After a bit of head scratching and debugging it turned out that it is
due to kprobe handler being interrupted by a tick that causes us to go
into (I think another) kprobe handler.

The culprit was kprobe_breakpoint_ss_handler() returning DBG_HOOK_ERROR
which leads to the Unexpected kernel BRK exception.

Reverting commit ba090f9c ("arm64: kprobes: Remove redundant
kprobe_step_ctx") seemed to fix the problem for me.

Further analysis showed that kcb->kprobe_status is set to
KPROBE_REENTER when the error occurs. By teaching
kprobe_breakpoint_ss_handler() to handle this status I can no  longer
reproduce the problem.
