2017-07-10btrfs: nowait aio: Correct assignment of posGoldwyn Rodrigues
Assigning pos for usage early messes up in append mode, where the pos is re-assigned in generic_write_checks(). Assign pos later to get the correct position to write from iocb->ki_pos. Since check_can_nocow also uses the value of pos, we shift generic_write_checks() before check_can_nocow(). Checks with IOCB_DIRECT are present in generic_write_checks(), so checking for IOCB_NOWAIT is enough. Also, put locking sequence in the fast path. This fixes a user visible bug, as reported: "apparently breaks several shell related features on my system. In zsh history stopped working, because no new entries are added anymore. I fist noticed the issue when I tried to build mplayer. It uses a shell script to generate a help_mp.h file: [...] Here is a simple testcase: % echo "foo" >> test % echo "foo" >> test % cat test foo % " Fixes: edf064e7c6fe ("btrfs: nowait aio support") CC: Jens Axboe <axboe@kernel.dk> Reported-by: Markus Trippelsdorf <markus@trippelsdorf.de> Link: https://lkml.kernel.org/r/20170704042306.GA274@x4 Signed-off-by: Goldwyn Rodrigues <rgoldwyn@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>

2017-07-10powerpc/kexec: Fix radix to hash kexec due to IAMR/AMORBalbir Singh
This patch fixes a crash seen while doing a kexec from radix mode to hash mode. Key 0 is special in hash and used in the RPN by default, we set the key values to 0 today. In radix mode key 0 is used to control supervisor<->user access. In hash key 0 is used by default, so the first instruction after the switch causes a crash on kexec. Commit 3b10d0095a1e ("powerpc/mm/radix: Prevent kernel execution of user space") introduced the setting of IAMR and AMOR values to prevent execution of user mode instructions from supervisor mode. We need to clean up these SPR's on kexec.

The AFS_ACE_READ and AFS_ACE_WRITE permission bits should not be used to make access decisions for the directory itself. They are meant to control access for the objects contained in that directory. Reading a directory is allowed if the AFS_ACE_LOOKUP bit is set. This would cause an incorrect access denied error for a directory with AFS_ACE_LOOKUP but not AFS_ACE_READ. The AFS_ACE_WRITE bit does not allow operations that modify the directory. For a directory with AFS_ACE_WRITE but neither AFS_ACE_INSERT nor AFS_ACE_DELETE, this would result in trying operations that would ultimately be denied by the server.

2017-07-09mqueue: fix a use-after-free in sys_mq_notify()Cong Wang
The retry logic for netlink_attachskb() inside sys_mq_notify() is nasty and vulnerable: 1) The sock refcnt is already released when retry is needed 2) The fd is controllable by user-space because we already release the file refcnt so we when retry but the fd has been just closed by user-space during this small window, we end up calling netlink_detachskb() on the error path which releases the sock again, later when the user-space closes this socket a use-after-free could be triggered. Setting 'sock' to NULL here should be sufficient to fix it.

2017-07-09rtc: rtctest: add check for problematic datesBenjamin Gaignard
Some dates could be problematic because they reach the limits of RTC hardware capabilities. This patch add various of them but since it will change RTC date it will be activated only when 'd' args is set.

2017-07-09tools: timer: add rtctest_setdateBenjamin Gaignard
This tool allow to set directly the time and date to a RTC device. Unlike other tools isn't doens't use "struct timeval" or "time_t" so it is safe for 32bits platforms when testing for y2038/2106 bug.

2017-07-10microblaze: move generic-y of exported headers to uapi/asm/KbuildMasahiro Yamada
Since commit fcc8487d477a ("uapi: export all headers under uapi directories"), all (and only) headers under uapi directories are exported, but asm-generic wrappers are still exceptions. To complete de-coupling the uapi from kernel headers, move generic-y of exported headers to uapi/asm/Kbuild. With this change, "make headers_install" will just need to parse uapi/asm/Kbuild to build up exported headers. For microblaze, "generic-y += siginfo.h" is doubled in asm/Kbuild and uapi/asm/Kbuild. So, the one in the former can be simply removed. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
