In inode.c:submit_compressed_extents(), before calling btrfs_submit_compressed_write() we start writeback for all pages, clear their dirty flag, unlock them, etc, but if btrfs_submit_compressed_write() fails (at the moment it can only fail with -ENOMEM), we never end the writeback on the pages, so any filemap_fdatawait_range() call will hang forever. We were also not calling the writepage end io hook, which means the corresponding ordered extent will never complete and all its waiters will block forever, such as a full fsync (via btrfs_wait_ordered_range()).

If we fail in submit_compressed_extents() before calling btrfs_submit_compressed_write(), we start and end the writeback for the pages (clear their dirty flag, unlock them, etc) but we don't tag the pages, nor the inode's mapping, with an error. This makes it impossible for a caller of filemap_fdatawait_range() (fsync, or transaction commit for e.g.) know that there was an error. Note that the return value of submit_compressed_extents() is useless, as that function is executed by a workqueue task and not directly by the fill_delalloc callback. This means the writepage/s callbacks of the inode's address space operations don't get that return value. Signed-off-by: Filipe Manana <fdmanana@suse.com> Signed-off-by: Chris Mason <clm@fb.com>

md_check_recovery will skip any recovery and also clear MD_RECOVERY_NEEDED if MD_RECOVERY_FROZEN is set. So when we clear _FROZEN, we must set _NEEDED and ensure that md_check_recovery gets run. Otherwise we could miss out on something that is needed. In particular, this can make it impossible to remove a failed device from an array is the 'recovery-needed' processing didn't happen.

Al Viro pointed out that the x86-64 csum_partial_copy_from_user() is somewhat confused about what it should do on errors, notably it mostly clears the uncopied end result buffer, but misses that for the initial alignment case. All users should check for errors, so it's dubious whether the clearing is even necessary, and Al also points out that we should probably clean up the calling conventions, but regardless of any future changes to this function, the fact that it is inconsistent is just annoying. So make the __get_user() failure path use the same error exit as all the other errors do.

Sasha Levin reports: "gcc5 changes the default standard to c11, which makes kernel build unhappy Explicitly define the kernel standard to be gnu89 which should keep everything working exactly like it was before gcc5" There are multiple small issues with the new default, but the biggest issue seems to be that the old - and very useful - GNU extension to allow a cast in front of an initializer has gone away. Patch updated by Kirill: "I'm pretty sure all gcc versions you can build kernel with supports -std=gnu89. cc-option is redunrant. We also need to adjust HOSTCFLAGS otherwise allmodconfig fails for me" Note by Andrew Pinski: "Yes it was reported and both problems relating to this extension has been added to gnu99 and gnu11. Though there are other issues with the kernel dealing with extern inline have different semantics between gnu89 and gnu99/11" End result: we may be able to move up to a newer stdc model eventually, but right now the newer models have some annoying deficiencies, so the traditional "gnu89" model ends up being the preferred one.

Pull ACPI and power management fixes from Rafael Wysocki: "These are three regression fixes, two recent (generic power domains, suspend-to-idle) and one older (cpufreq), an ACPI blacklist entry for one more machine having problems with Windows 8 compatibility, a minor cpufreq driver fix (cpufreq-dt) and a fixup for new callback definitions (generic power domains). Specifics: - Fix a crash in the suspend-to-idle code path introduced by a recent commit that forgot to check a pointer against NULL before dereferencing it (Dmitry Eremin-Solenikov). - Fix a boot crash on Exynos5 introduced by a recent commit making that platform use generic Device Tree bindings for power domains which exposed a weakness in the generic power domains framework leading to that crash (Ulf Hansson). - Fix a crash during system resume on systems where cpufreq depends on Operation Performance Points (OPP) for functionality, but CONFIG_OPP is not set. This leads the cpufreq driver registration to fail, but the resume code attempts to restore the pre-suspend cpufreq configuration (which does not exist) nevertheless and crashes. From Geert Uytterhoeven. - Add a new ACPI blacklist entry for Dell Vostro 3546 that has problems if it is reported as Windows 8 compatible to the BIOS (Adam Lee). - Fix swapped arguments in an error message in the cpufreq-dt driver (Abhilash Kesavan). - Fix up the prototypes of new callbacks in struct generic_pm_domain to make them more useful.

Found by the UC-KLEE tool: A user could supply less input to firewire-cdev ioctls than write- or write/read-type ioctl handlers expect. The handlers used data from uninitialized kernel stack then. This could partially leak back to the user if the kernel subsequently generated fw_cdev_event_'s (to be read from the firewire-cdev fd) which notably would contain the _u64 closure field which many of the ioctl argument structures contain. The fact that the handlers would act on random garbage input is a lesser issue since all handlers must check their input anyway. The fix simply always null-initializes the entire ioctl argument buffer regardless of the actual length of expected user input. That is, a runtime overhead of memset(..., 40) is added to each firewirew-cdev ioctl() call. [Comment from Clemens Ladisch: This part of the stack is most likely to be already in the cache.] Remarks: - There was never any leak from kernel stack to the ioctl output buffer itself. IOW, it was not possible to read kernel stack by a read-type or write/read-type ioctl alone; the leak could at most happen in combination with read()ing subsequent event data. - The actual expected minimum user input of each ioctl from include/uapi/linux/firewire-cdev.h is, in bytes: [0x00] = 32, [0x05] = 4, [0x0a] = 16, [0x0f] = 20, [0x14] = 16, [0x01] = 36, [0x06] = 20, [0x0b] = 4, [0x10] = 20, [0x15] = 20, [0x02] = 20, [0x07] = 4, [0x0c] = 0, [0x11] = 0, [0x16] = 8, [0x03] = 4, [0x08] = 24, [0x0d] = 20, [0x12] = 36, [0x17] = 12, [0x04] = 20, [0x09] = 24, [0x0e] = 4, [0x13] = 40, [0x18] = 4.

A chapter is added to describe the trackpoint packets. A section is added to describe the behaviour of the knob crc_enabled in sysfs. The introduction of the documentation only mentioned v1/v2, but in the last part it already contains explanation of v3 and v4. The introduction is updated.

The detection of crc_enabled is known to fail for Fujitsu H730. A DMI blacklist is added for that, but it can be expected that other laptops will pop up with this. Here a sysfs knob is provided to alter the behaviour of crc_enabled. Writing 0 or 1 to it sets the variable to 0 or 1. Reading it will show the crc_enabled variable (0 or 1).

In the past, no elantech was known with 3 touchpad mouse buttons. Fujitsu H730 is the first known elantech with a middle button. This commit enables this middle button. For backwards compatibility, the Fujitsu is detected via DMI, and only for this one 3 buttons will be announced.

Sometimes on Dell Latitude laptops psmouse/alps driver receive invalid ALPS protocol V3 packets with bit7 set in last byte. More often it can be reproduced on Dell Latitude E6440 or E7440 with closed lid and pushing cover above touchpad. If bit7 in last packet byte is set then it is not valid ALPS packet. I was told that ALPS devices never send these packets. It is not know yet who send those packets, it could be Dell EC, bug in BIOS and also bug in touchpad firmware... With this patch alps driver does not process those invalid packets, but instead of reporting PSMOUSE_BAD_DATA, getting into out of sync state, getting back in sync with the next byte and spam dmesg we return PSMOUSE_FULL_PACKET. If driver is truly out of sync we'll fail the checks on the next byte and report PSMOUSE_BAD_DATA then.
