jfs: set i_ctime when setting ACL

2014-02-13T21:56:05Z

This fixes a regression in 3.14-rc1 where xfstests generic/307 fails. jfs sets the ctime on the inode when writing an xattr. Previously, jfs went ahead and stored an acl that can be completely represented in the traditional permission bits, so the ctime was always set in the xattr code. The new code doesn't bother storing the acl in that case, thus the ctime isn't getting set. Signed-off-by: Dave Kleikamp Reported-by: Michael L. Semon

jfs: fix generic posix ACL regression

2014-02-08T16:50:58Z

I missed a couple errors in reviewing the patches converting jfs to use the generic posix ACL function. Setting ACL's currently fails with -EOPNOTSUPP. Signed-off-by: Dave Kleikamp Reported-by: Michael L. Semon Reviewed-by: Christoph Hellwig

Pull core block IO changes from Jens Axboe: "The major piece in here is the immutable bio_ve series from Kent, the rest is fairly minor. It was supposed to go in last round, but various issues pushed it to this release instead. The pull request contains: - Various smaller blk-mq fixes from different folks. Nothing major here, just minor fixes and cleanups. - Fix for a memory leak in the error path in the block ioctl code from Christian Engelmayer. - Header export fix from CaiZhiyong. - Finally the immutable biovec changes from Kent Overstreet. This enables some nice future work on making arbitrarily sized bios possible, and splitting more efficient. Related fixes to immutable bio_vecs: - dm-cache immutable fixup from Mike Snitzer. - btrfs immutable fixup from Muthu Kumar. - bio-integrity fix from Nic Bellinger, which is also going to stable" * 'for-3.14/core' of git://git.kernel.dk/linux-block: (44 commits) xtensa: fixup simdisk driver to work with immutable bio_vecs block/blk-mq-cpu.c: use hotcpu_notifier() blk-mq: for_each_* macro correctness block: Fix memory leak in rw_copy_check_uvector() handling bio-integrity: Fix bio_integrity_verify segment start bug block: remove unrelated header files and export symbol blk-mq: uses page->list incorrectly blk-mq: use __smp_call_function_single directly btrfs: fix missing increment of bi_remaining Revert "block: Warn and free bio if bi_end_io is not set" block: Warn and free bio if bi_end_io is not set blk-mq: fix initializing request's start time block: blk-mq: don't export blk_mq_free_queue() block: blk-mq: make blk_sync_queue support mq block: blk-mq: support draining mq queue dm cache: increment bi_remaining when bi_end_io is restored block: fixup for generic bio chaining block: Really silence spurious compiler warnings block: Silence spurious compiler warnings block: Kill bio_pair_split() ...

jfs: use generic posix ACL infrastructure

2014-01-26T04:58:22Z

Copy the scheme I introduced to btrfs many years ago to only use the xattr handler for ACLs, but pass plain attrs straight through. Signed-off-by: Christoph Hellwig Reviewed-by: Dave Kleikamp Signed-off-by: Al Viro

jfs: fix xattr value size overflow in __jfs_setxattr

2014-01-02T17:36:56Z

There is a potential overflow if the specified EA value size is greater than USHRT_MAX because the size of value is limited by the on-disk format (i.e, __le16), this issue could be reflected via the tests below: # touch /jfs/testfile # setfattr -n user.comment -v `perl -e 'print "A"x65536'` /jfs/testfile setfattr: /jfs/testfile: Invalid argument Syslog: ... jfs_xsetattr: xattr_size = 21, new_size = 65557 This patch add pre-checkups of EA value size against USHRT_MAX to avoid this problem, and return -E2BIG which is consistent with the VFS setxattr interface. Moreover, fix the debug code to print the correct function name. With this fix: setfattr: /jfs/testfile: Argument list too long Signed-off-by: Jie Liu Signed-off-by: Dave Kleikamp

block: Abstract out bvec iterator

2013-11-24T06:33:47Z

Immutable biovecs are going to require an explicit iterator. To implement immutable bvecs, a later patch is going to add a bi_bvec_done member to this struct; for now, this patch effectively just renames things.
