2017-02-17MIPS: ip27: Disable qlge driver in defconfigArnd Bergmann
One of the last remaining failures in kernelci.org is for a gcc bug: drivers/net/ethernet/qlogic/qlge/qlge_main.c:4819:1: error: insn does not satisfy its constraints: drivers/net/ethernet/qlogic/qlge/qlge_main.c:4819:1: internal compiler error: in extract_constrain_insn, at recog.c:2190 This is apparently broken in gcc-6 but fixed in gcc-7, and I cannot reproduce the problem here. However, it is clear that ip27_defconfig does not actually need this driver as the platform has only PCI-X but not PCIe, and the qlge adapter in turn is PCIe-only. The driver was originally enabled in 2010 along with lots of other drivers. Fixes: 59d302b342e5 ("MIPS: IP27: Make defconfig useful again.")

2017-02-17MIPS: Lantiq: Keep ethernet enabled during bootFelix Fietkau
Disabling ethernet during reboot (only to enable it again when the ethernet driver attaches) can put the chip into a faulty state where it corrupts the header of all incoming packets. This happens if packets arrive during the time window where the core is disabled, and it can be easily reproduced by rebooting while sending a flood ping to the broadcast address.

2017-02-17MIPS: OCTEON: Fix copy_from_user fault handling for large buffersJames Cowgill
If copy_from_user is called with a large buffer (>= 128 bytes) and the userspace buffer refers partially to unreadable memory, then it is possible for Octeon's copy_from_user to report the wrong number of bytes have been copied. In the case where the buffer size is an exact multiple of 128 and the fault occurs in the last 64 bytes, copy_from_user will report that all the bytes were copied successfully but leave some garbage in the destination buffer. The bug is in the main __copy_user_common loop in octeon-memcpy.S where in the middle of the loop, src and dst are incremented by 128 bytes. The l_exc_copy fault handler is used after this but that assumes that "src < THREAD_BUADDR($28)". This is not the case if src has already been incremented. Fix by adding an extra fault handler which rewinds the src and dst pointers 128 bytes before falling though to l_exc_copy. Thanks to the pwritev test from the strace test suite for originally highlighting this bug! Fixes: 5b3b16880f40 ("MIPS: Add Cavium OCTEON processor support ...")

2017-02-17MIPS: Fix special case in 64 bit IP checksumming.Ralf Baechle
For certain arguments such as saddr = 0xc0a8fd60, daddr = 0xc0a8fda1, len = 80, proto = 17, sum = 0x7eae049d there will be a carry when folding the intermediate 64 bit checksum to 32 bit but the code doesn't add the carry back to the one's complement sum, thus an incorrect result will be generated.

2017-02-17btrfs: pass fs_info to (more) routines that are only called with extent_rootJeff Mahoney
Outside of interactions with qgroups, the roots passed in extent-tree.c are usually passed to ensure that we don't do refcounts on log trees or to get the allocation profile for an allocation request. Otherwise, it operates on the extent root. This patch converts some more routines in extent-tree.c that are always called with the extent root to accept an fs_info instead.

2017-02-17btrfs: qgroup: Move half of the qgroup accounting time out of commit transQu Wenruo
Just as Filipe pointed out, the most time consuming parts of qgroup are btrfs_qgroup_account_extents() and btrfs_qgroup_prepare_account_extents(). Which both call btrfs_find_all_roots() to get old_roots and new_roots ulist. What makes things worse is, we're calling that expensive btrfs_find_all_roots() at transaction committing time with TRANS_STATE_COMMIT_DOING, which will blocks all incoming transaction. Such behavior is necessary for @new_roots search as current btrfs_find_all_roots() can't do it correctly so we do call it just before switch commit roots. However for @old_roots search, it's not necessary as such search is based on commit_root, so it will always be correct and we can move it out of transaction committing. This patch moves the @old_roots search part out of commit_transaction(), so in theory we can half the time qgroup time consumption at commit_transaction(). But please note that, this won't speedup qgroup overall, the total time consumption is still the same, just reduce the performance stall.
