Wong" , Linux Kernel Mailing List , linux-xfs , Eric Sandeen Hi Linus, Here are some patches for 4.18 to fix regressions, accounting problems, overflow problems, and to strengthen metadata validation to prevent corruption. This series has been run through a full xfstests run over the weekend and through a quick xfstests run against this morning's master, with no major failures reported. --D The following changes since commit ce397d215ccd07b8ae3f71db689aedb85d56ab40: Linux 4.18-rc1 (2018-06-17 08:04:49 +0900) are available in the Git repository at: git://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git tags/xfs-4.18-fixes-2 for you to fetch changes up to d8cb5e42378918e00eda58792f3ab86dd1e7d214: xfs: fix fdblocks accounting w/ RMAPBT per-AG reservation (2018-06-24 12:00:12 -0700) ---------------------------------------------------------------- Changes since last update: - More metadata validation strengthening to prevent crashes. - Fix extent offset overflow problem when insert_range on a 512b block fs - Fix some off-by-one errors in the realtime fsmap code - Fix some math errors in the default resblks calculation when free space is low - Fix a problem where stale page contents are exposed via mmap read after a zero_range at eof - Fix accounting problems with per-ag reservations causing statfs reports to vary incorrectly ---------------------------------------------------------------- Christoph Hellwig (1): xfs: simplify xfs_bmap_punch_delalloc_range Darrick J. Wong (8): xfs: allow empty transactions while frozen xfs: don't trip over negative free space in xfs_reserve_blocks xfs: don't allow insert-range to shift extents past the maximum offset xfs: recheck reflink state after grabbing ILOCK_SHARED for a write xfs: fix uninitialized field in rtbitmap fsmap backend xfs: fix off-by-one error in xfs_rtalloc_query_range xfs: ensure post-EOF zeroing happens after zeroing part of a file xfs: fix fdblocks accounting w/ RMAPBT per-AG reservation Dave Chinner (2): xfs: More robust inode extent count validation xfs: xfs_iflush_abort() can be called twice on cluster writeback failure fs/xfs/libxfs/xfs_ag_resv.c | 31 ++++++++++-- fs/xfs/libxfs/xfs_bmap.c | 26 +++++++++++ fs/xfs/libxfs/xfs_bmap.h | 2 + fs/xfs/libxfs/xfs_format.h | 5 ++ fs/xfs/libxfs/xfs_inode_buf.c | 76 ++++++++++++++++++------------ fs/xfs/libxfs/xfs_rtbitmap.c | 4 +- fs/xfs/xfs_bmap_util.c | 106 +++++++++++++++++++++--------------------- fs/xfs/xfs_fsmap.c | 4 +- fs/xfs/xfs_fsops.c | 2 +- fs/xfs/xfs_inode.c | 57 +++++++++-------------- fs/xfs/xfs_iomap.c | 15 +++++- fs/xfs/xfs_trans.c | 7 ++- 12 files changed, 205 insertions(+), 130 deletions(-)
