Specifics: - Fix ACPI resources management problems introduced by the recent rework of the code in question (Jiang Liu) and a build issue introduced by those changes (Joachim Nilsson). - Fix a recent suspend-to-idle regression on systems where entering idle states causes local timers to stop, prevent suspend-to-idle from crashing in restricted configurations (no cpuidle driver, cpuidle disabled etc.) and clean up the idle loop somewhat while at it (Rafael J Wysocki). - Fix build problem in the cpufreq ppc driver (Geert Uytterhoeven). - Allow the ACPI backlight driver module to be loaded if ACPI is disabled which helps the i915 driver in those configurations (stable-candidate) and change the code to help debug unusual use cases (Chris Wilson). - Wakeup IRQ management changes in v3.18 caused some drivers on the at91 platform to trigger a warning from the IRQ core related to an unexpected combination of interrupt action handler flags. However, on at91 a timer IRQ is shared with some other devices (including system wakeup ones) and that leads to the unusual combination of flags in question. To make it possible to avoid the warning introduce a new interrupt action handler flag (which can be used by drivers to indicate the special case to the core) and rework the problematic at91 drivers to use it and work as expected during system suspend/resume.

When using the fast file fsync code path we can miss the fact that new writes happened since the last file fsync and therefore return without waiting for the IO to finish and write the new extents to the fsync log. Here's an example scenario where the fsync will miss the fact that new file data exists that wasn't yet durably persisted: 1. fs_info->last_trans_committed == N - 1 and current transaction is transaction N (fs_info->generation == N); 2. do a buffered write; 3. fsync our inode, this clears our inode's full sync flag, starts an ordered extent and waits for it to complete - when it completes at btrfs_finish_ordered_io(), the inode's last_trans is set to the value N (via btrfs_update_inode_fallback -> btrfs_update_inode -> btrfs_set_inode_last_trans); 4. transaction N is committed, so fs_info->last_trans_committed is now set to the value N and fs_info->generation remains with the value N; 5. do another buffered write, when this happens btrfs_file_write_iter sets our inode's last_trans to the value N + 1 (that is fs_info->generation + 1 == N + 1); 6. transaction N + 1 is started and fs_info->generation now has the value N + 1; 7. transaction N + 1 is committed, so fs_info->last_trans_committed is set to the value N + 1; 8. fsync our inode - because it doesn't have the full sync flag set, we only start the ordered extent, we don't wait for it to complete (only in a later phase) therefore its last_trans field has the value N + 1 set previously by btrfs_file_write_iter(), and so we have: inode->last_trans <= fs_info->last_trans_committed (N + 1) (N + 1) Which made us not log the last buffered write and exit the fsync handler immediately, returning success (0) to user space and resulting in data loss after a crash. This can actually be triggered deterministically and the following excerpt from a testcase I made for xfstests triggers the issue. It moves a dummy file across directories and then fsyncs the old parent directory - this is just to trigger a transaction commit, so moving files around isn't directly related to the issue but it was chosen because running 'sync' for example does more than just committing the current transaction, as it flushes/waits for all file data to be persisted. The issue can also happen at random periods, since the transaction kthread periodicaly commits the current transaction (about every 30 seconds by default). The body of the test is: _scratch_mkfs >> $seqres.full 2>&1 _init_flakey _mount_flakey # Create our main test file 'foo', the one we check for data loss. # By doing an fsync against our file, it makes btrfs clear the 'needs_full_sync' # bit from its flags (btrfs inode specific flags). $XFS_IO_PROG -f -c "pwrite -S 0xaa 0 8K" \ -c "fsync" $SCRATCH_MNT/foo | _filter_xfs_io # Now create one other file and 2 directories. We will move this second file # from one directory to the other later because it forces btrfs to commit its # currently open transaction if we fsync the old parent directory. This is # necessary to trigger the data loss bug that affected btrfs. mkdir $SCRATCH_MNT/testdir_1 touch $SCRATCH_MNT/testdir_1/bar mkdir $SCRATCH_MNT/testdir_2 # Make sure everything is durably persisted. sync # Write more 8Kb of data to our file. $XFS_IO_PROG -c "pwrite -S 0xbb 8K 8K" $SCRATCH_MNT/foo | _filter_xfs_io # Move our 'bar' file into a new directory. mv $SCRATCH_MNT/testdir_1/bar $SCRATCH_MNT/testdir_2/bar # Fsync our first directory. Because it had a file moved into some other # directory, this made btrfs commit the currently open transaction. This is # a condition necessary to trigger the data loss bug. $XFS_IO_PROG -c "fsync" $SCRATCH_MNT/testdir_1 # Now fsync our main test file. If the fsync succeeds, we expect the 8Kb of # data we wrote previously to be persisted and available if a crash happens. # This did not happen with btrfs, because of the transaction commit that # happened when we fsynced the parent directory. $XFS_IO_PROG -c "fsync" $SCRATCH_MNT/foo # Simulate a crash/power loss. _load_flakey_table $FLAKEY_DROP_WRITES _unmount_flakey _load_flakey_table $FLAKEY_ALLOW_WRITES _mount_flakey # Now check that all data we wrote before are available. echo "File content after log replay:" od -t x1 $SCRATCH_MNT/foo status=0 exit The expected golden output for the test, which is what we get with this fix applied (or when running against ext3/4 and xfs), is: wrote 8192/8192 bytes at offset 0 XXX Bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec) wrote 8192/8192 bytes at offset 8192 XXX Bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec) File content after log replay: 0000000 aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa * 0020000 bb bb bb bb bb bb bb bb bb bb bb bb bb bb bb bb * 0040000 Without this fix applied, the output shows the test file does not have the second 8Kb extent that we successfully fsynced: wrote 8192/8192 bytes at offset 0 XXX Bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec) wrote 8192/8192 bytes at offset 8192 XXX Bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec) File content after log replay: 0000000 aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa * 0020000 So fix this by skipping the fsync only if we're doing a full sync and if the inode's last_trans is <= fs_info->last_trans_committed, or if the inode is already in the log. Also remove setting the inode's last_trans in btrfs_file_write_iter since it's useless/unreliable. Also because btrfs_file_write_iter no longer sets inode->last_trans to fs_info->generation + 1, don't set last_trans to 0 if we bail out and don't bail out if last_trans is 0, otherwise something as simple as the following example wouldn't log the second write on the last fsync: 1. write to file 2. fsync file 3. fsync file |--> btrfs_inode_in_log() returns true and it set last_trans to 0 4. write to file |--> btrfs_file_write_iter() no longers sets last_trans, so it remained with a value of 0 5. fsync |--> inode->last_trans == 0, so it bails out without logging the second write A test case for xfstests will be sent soon.

With certain restrictions it is possible for a wakeup device to share an IRQ with an IRQF_NO_SUSPEND user, and the warnings introduced by commit cab303be are spurious. The new IRQF_COND_SUSPEND flag allows drivers to tell the core when these restrictions are met, allowing spurious warnings to be silenced. This patch documents how IRQF_COND_SUSPEND is expected to be used, updating some of the text now made invalid by its addition.

The IRQ line connected to the DBGU UART is often shared with a timer device which request the IRQ with IRQF_NO_SUSPEND. Since the UART driver is correctly disabling IRQs when entering suspend we can safely request the IRQ with IRQF_COND_SUSPEND so that irq core will not complain about mixing IRQF_NO_SUSPEND and !IRQF_NO_SUSPEND. Rework the interrupt handler to wake the system up when an interrupt happens on the DEBUG_UART while the system is suspended.

The watchdog interrupt (only used when activating software watchdog) shouldn't be suspended when entering suspend mode, because it is shared with a timer device (which request the line with IRQF_NO_SUSPEND) and once the watchdog "Mode Register" has been written, it cannot be changed (which means we cannot disable the watchdog interrupt when entering suspend).

由 Rafael J. Wysocki 提交于
Commit 38106313 (PM / sleep: Re-implement suspend-to-idle handling) overlooked the fact that entering some sufficiently deep idle states by CPUs may cause their local timers to stop and in those cases it is necessary to switch over to a broadcast timer prior to entering the idle state. If the cpuidle driver in use does not provide the new ->enter_freeze callback for any of the idle states, that problem affects suspend-to-idle too, but it is not taken into account after the changes made by commit 38106313. Fix that by changing the definition of cpuidle_enter_freeze() and re-arranging of the code in cpuidle_idle_call(), so the former does not call cpuidle_enter() any more and the fallback case is handled by cpuidle_idle_call() directly.

Commit: f31a9f7c ("x86/xsaves: Use xsaves/xrstors to save and restore xsave area") introduced alternative instructions for XSAVES/XRSTORS and commit: adb9d526 ("x86/xsaves: Add xsaves and xrstors support for booting time") added support for the XSAVES/XRSTORS instructions at boot time. Unfortunately both failed to properly protect them against faulting: The 'xstate_fault' macro will use the closest label named '1' backward and that ends up in the .altinstr_replacement section rather than in .text. This means that the kernel will never find in the __ex_table the .text address where this instruction might fault, leading to serious problems if userspace manages to trigger the fault.

Commit 8634b51f (locks: convert lease handling to file_lock_context) introduced a regression in the handling of lease upgrade/downgrades. In the event that we already have a lease on a file and are going to either upgrade or downgrade it, we skip doing any list insertion or deletion and simply re-call lm_setup on the existing lease. As of commit 8634b51f however, we end up calling lm_setup on the lease that was passed in, instead of on the existing lease. This causes us to leak the fasync_struct that was allocated in the event that there was not already an existing one (as it always appeared that there wasn't one). Fixes: 8634b51f (locks: convert lease handling to file_lock_context) Reported-and-Tested-by: NDaniel Wagner <daniel.wagner@bmw-carit.de> Signed-off-by: NJeff Layton <jeff.layton@primarydata.com>

Merge tag 'ecryptfs-4.0-rc3-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs Pull eCryptfs fixes from Tyler Hicks: "Fixes for proper ioctl handling and an untriggerable buffer overflow - The eCryptfs ioctl handling functions should only pass known-good ioctl commands to the lower filesystem - A static checker found a potential buffer overflow. Upon inspection, it is not triggerable due to input validation performed on the mount parameters" * tag 'ecryptfs-4.0-rc3-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs: eCryptfs: don't pass fs-specific ioctl commands through eCryptfs: ensure copy to crypt_stat->cipher does not overrun

The irq line used by the PMC block is shared with several peripherals including the init timer which is registering its handler with IRQF_NO_SUSPEND. Implement the appropriate suspend/resume callback for the PMC irqchip, and inform irq core that PMC irq handler can be safely called while the system is suspended by setting IRQF_COND_SUSPEND.

The IRQ line used by the RTC device is usually shared with the system timer (PIT) on at91 platforms. Since timers are registering their handlers with IRQF_NO_SUSPEND, we should expect being called in suspended state, and properly wake the system up when this is the case. Set IRQF_COND_SUSPEND flag when registering the IRQ handler to inform irq core that it can safely be called while the system is suspended.

Export pm_system_wakeup function to allow irq handlers to deal with system wakeup. This is needed for shared IRQ lines where one of the handler is registered with IRQF_NO_SUSPEND, while the other ones want to configure it as a wakeup source. In this specific case, irq core does not handle the wakeup process and leave the decision to each irq handler.
