2017-01-12x86/unwind: Silence warnings for non-current tasksJosh Poimboeuf
There are a handful of callers to save_stack_trace_tsk() and show_stack() which try to unwind the stack of a task other than current. In such cases, it's remotely possible that the task is running on one CPU while the unwinder is reading its stack from another CPU, causing the unwinder to see stack corruption. These cases seem to be mostly harmless. The unwinder has checks which prevent it from following bad pointers beyond the bounds of the stack. So it's not really a bug as long as the caller understands that unwinding another task will not always succeed. Since stack "corruption" on another task's stack isn't necessarily a bug, silence the warnings when unwinding tasks other than current.

2017-01-09x86/microcode/intel: Use correct buffer size for saving microcode dataJunichi Nomura
In generic_load_microcode(), curr_mc_size is the size of the last allocated buffer and since we have this performance "optimization" there to vmalloc a new buffer only when the current one is bigger, curr_mc_size ends up becoming the size of the biggest buffer we've seen so far. However, we end up saving the microcode patch which matches our CPU and its size is not curr_mc_size but the respective mc_size during the iteration while we're staring at it. So save that mc_size into a separate variable and use it to store the previously found microcode buffer. Without this fix, we could get oops like this: BUG: unable to handle kernel paging request at ffffc9000e30f000 IP: __memcpy+0x12/0x20 ...

It used to do sync_core() which did do CPUID but c198b121b1a1 ("x86/asm: Rewrite sync_core() to use IRET-to-self") changed the sync_core() implementation so we better make the microcode loading case explicit, as the SDM documents it.

2017-01-04net: systemport: Pad packet before inserting TSBFlorian Fainelli
Inserting the TSB means adding an extra 8 bytes in front the of packet that is going to be used as metadata information by the TDMA engine, but stripped off, so it does not really help with the packet padding. For some odd packet sizes that fall below the 60 bytes payload (e.g: ARP) we can end-up padding them after the TSB insertion, thus making them 64 bytes, but with the TDMA stripping off the first 8 bytes, they could still be smaller than 64 bytes which is required to ingress the switch. Fix this by swapping the padding and TSB insertion, guaranteeing that the packets have the right sizes.

2017-01-03xfs: fix crash and data corruption due to removal of busy COW extentsChristoph Hellwig
There is a race window between write_cache_pages calling clear_page_dirty_for_io and XFS calling set_page_writeback, in which the mapping for an inode is tagged neither as dirty, nor as writeback. If the COW shrinker hits in exactly that window we'll remove the delayed COW extents and writepages trying to write it back, which in release kernels will manifest as corruption of the bmap btree, and in debug kernels will trip the ASSERT about now calling xfs_bmapi_write with the COWFORK flag for holes. A complex customer load manages to hit this window fairly reliably, probably by always having COW writeback in flight while the cow shrinker runs. This patch adds another check for having the I_DIRTY_PAGES flag set, which is still set during this race window. While this fixes the problem I'm still not overly happy about the way the COW shrinker works as it still seems a bit fragile. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Darrick J.

2017-01-03benet: stricter vxlan offloading check in be_features_checkSabrina Dubroca
When VXLAN offloading is enabled, be_features_check() tries to check if an encapsulated packet is indeed a VXLAN packet. The check is not strict enough, and considers any UDP-encapsulated ethernet frame with a 8-byte tunnel header as being VXLAN. Unfortunately, both GENEVE and VXLAN-GPE have a 8-byte header, so they get through this check. Force the UDP destination port to be the one that has been offloaded to hardware. Without this, GENEVE-encapsulated packets can end up having an incorrect checksum when both a GENEVE and a VXLAN (offloaded) tunnel are configured. This is similar to commit a547224dceed ("mlx4e: Do not attempt to offload VXLAN ports that are unrecognized"). Signed-off-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S.

2017-01-03ipv4: Do not allow MAIN to be alias for new LOCAL w/ custom rulesAlexander Duyck
In the case of custom rules being present we need to handle the case of the LOCAL table being intialized after the new rule has been added. To address that I am adding a new check so that we can make certain we don't use an alias of MAIN for LOCAL when allocating a new table.
