2015-09-02Merge branch 'for-4.3/core' of git://git.kernel.dk/linux-blockLinus Torvalds
Pull core block updates from Jens Axboe: "This first core part of the block IO changes contains: - Cleanup of the bio IO error signaling from Christoph. We used to rely on the uptodate bit and passing around of an error, now we store the error in the bio itself. - Improvement of the above from myself, by shrinking the bio size down again to fit in two cachelines on x86-64. - Revert of the max_hw_sectors cap removal from a revision again, from Jeff Moyer. This caused performance regressions in various tests. Reinstate the limit, bump it to a more reasonable size instead. - Make /sys/block/<dev>/queue/discard_max_bytes writeable, by me. Most devices have huge trim limits, which can cause nasty latencies when deleting files. Enable the admin to configure the size down. We will look into having a more sane default instead of UINT_MAX sectors. - Improvement of the SGP gaps logic from Keith Busch. - Enable the block core to handle arbitrarily sized bios, which enables a nice simplification of bio_add_page() (which is an IO hot path). From Kent. - Improvements to the partition io stats accounting, making it faster. From Ming Lei. - Also from Ming Lei, a basic fixup for overflow of the sysfs pending file in blk-mq, as well as a fix for a blk-mq timeout race condition. - Ming Lin has been carrying Kents above mentioned patches forward for a while, and testing them. Ming also did a few fixes around that. - Sasha Levin found and fixed a use-after-free problem introduced by the bio->bi_error changes from Christoph. - Small blk cgroup cleanup from Viresh Kumar" * 'for-4.3/core' of git://git.kernel.dk/linux-block: (26 commits) blk: Fix bio_io_vec index when checking bvec gaps block: Replace SG_GAPS with new queue limits mask block: bump BLK_DEF_MAX_SECTORS to 2560 Revert "block: remove artifical max_hw_sectors cap" blk-mq: fix race between timeout and freeing request blk-mq: fix buffer overflow when reading sysfs file of 'pending' Documentation: update notes in biovecs about arbitrarily sized bios block: remove bio_get_nr_vecs() fs: use helper bio_add_page() instead of open coding on bi_io_vec block: kill merge_bvec_fn() completely md/raid5: get rid of bio_fits_rdev() md/raid5: split bio for chunk_aligned_read block: remove split code in blkdev_issue_{discard,write_same} btrfs: remove bio splitting and merge_bvec_fn() calls bcache: remove driver private bio splitting code block: simplify bio_add_page() block: make generic_make_request handle arbitrarily sized bios blk-cgroup: Drop unlikely before IS_ERR(_OR_NULL) block: don't access bio->bi_error after bio_put() block: shrink struct bio down to 2 cache lines again ...

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull user namespace updates from Eric Biederman: "This finishes up the changes to ensure proc and sysfs do not start implementing executable files, as the there are application today that are only secure because such files do not exist. It akso fixes a long standing misfeature of /proc/<pid>/mountinfo that did not show the proper source for files bind mounted from /proc/<pid>/ns/*. It also straightens out the handling of clone flags related to user namespaces, fixing an unnecessary failure of unshare(CLONE_NEWUSER) when files such as /proc/<pid>/environ are read while <pid> is calling unshare. This winds up fixing a minor bug in unshare flag handling that dates back to the first version of unshare in the kernel. Finally, this fixes a minor regression caused by the introduction of sysfs_create_mount_point, which broke someone's in house application, by restoring the size of /sys/fs/cgroup to 0 bytes. Apparently that application uses the directory size to determine if a tmpfs is mounted on /sys/fs/cgroup. The bind mount escape fixes are present in Al Viros for-next branch. and I expect them to come from there. The bind mount escape is the last of the user namespace related security bugs that I am aware of" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: fs: Set the size of empty dirs to 0. userns,pidns: Force thread group sharing, not signal handler sharing. unshare: Unsharing a thread does not require unsharing a vm nsfs: Add a show_path method to fix mountinfo mnt: fs_fully_visible enforce noexec and nosuid if !SB_I_NOEXEC vfs: Commit to never having exectuables on proc and sysfs.
