9 years agoWhen delivering a signal with default disposition to the thread,
kib [Fri, 29 May 2015 16:26:08 +0000 (16:26 +0000)]
When delivering a signal with default disposition to the thread,
tdsigwakeup() increases the priority of the low-priority threads, to
give them a chance to be terminated timely.  Also, kernel allows user
to signal kernel processes.  The combined effect is that signalling
idle process bump a priority of the selected delivery thread, which
starts eating CPU.

Check for the delivery thread be an idle thread and do not raise its
priority then.

The signal delivery to the kernel threads must be opt-in feature.
Kernel thread should explicitely declare the ability to handle signals
directed to it.  E.g., nfsd threads check for signal as an indication
of exit request.

Most threads do not handle signals at all, and queuing the signal to
them causes odd side-effects.  Most innocent consequence is the memory
leak due to queued ksiginfo, which is never deleted from the sigqueue.
Code to prevent even queuing signals to the kernel threads is trivial,
but it requires careful examination of each call to kproc/kthread
creation to decide should the signalling be allowed.  The commit is a
stop-gap measure which fixes the immediate case for now.

sfxge: do not use DEBUG_FLAGS to enable extra debug checks

DEBUG_FLAGS are set to DEBUG option value when kernel is built.
For example, it is -g in GENERIC config to have debug symbols.
Also DEBUG_FLAGS are used to determine if ctfconvert should keep
debug symbols.
Since we redefined DEBUG_FLAGS, debug symbols were always missing.
ctfconvert complains about it during kernel build.
It is incorrect to append DEBUG_FLAGS, since if DEBUG has no -g (or
similar), we'll have no debug symbols and ctfconvert will complain.
If it incorrect to always have -g in our DEBUG_FLAGS, since debug
symbols presence should be controllable by kernel config.
So, just add disabled by default addition of -DDEBUG=1 to CFLAGS.

The wrong commit message was given with r283632.  This is the correct message.

- Updated all files with 2015 Avago copyright, and updated LSI's copyright
  dates.

- Changed all of the PCI device strings from LSI to Avago Technologies (LSI).

- Added a sysctl variable to control how StartStopUnit behavior works. User can
  select to spin down disks based on if disk is SSD or HDD.

- Inquiry data is required to tell if a disk will support SSU at shutdown or
  not. Due to the addition of mpssas_async, which gets Advanced Info but not
  Inquiry data, the setting of supports_SSU was moved to the
  mpssas_scsiio_complete function, which snoops for any Inquiry commands. And,
  since disks are shutdown as a target and not a LUN, this process was
  simplified by basing it on targets and not LUNs.

- Added a sysctl variable that sets the amount of time to retry after sending a
  failed SATA ID command. This helps with some bad disks and large disks that
  require a lot of time to spin up. Part of this change was to add a callout to
  handle timeouts with the SATA ID command. The callout function is called
  mpssas_ata_id_timeout(). (Fixes PR 191348)

- Changed the way resets work by allowing I/O to continue to devices that are
  not currently under a reset condition. This uses devq's instead of simq's and
  makes use of the MPSSAS_TARGET_INRESET flag. This change also adds a function
  called mpssas_prepare_tm().

- Some changes were made to reduce code duplication when getting a SAS address
  for a SATA disk.

- Fixed some formatting and whitespace.

- Bump version of mps driver to 9.255.01.00-fbsd
