Hi Linus, Please pull overlayfs update for 6.7. Most of the changes in this update have been sitting in linux-next for several weeks, based on two prerequisite vfs topic branches. Last week, after the vfs branches were merged, I rebased overlayfs-next to reduce noise. Last week, I also added patches for new mount options to replace the lowerdir append syntax that we disabled in v6.6-rc6 and v6.5.8. This branch has gone through the usual overlayfs test routines and it merges cleanly with master branch of the moment. Thanks, Amir. ---------------------------------------------------------------- The following changes since commit 14ab6d425e80674b6a0145f05719b11e82e64824: Merge tag 'vfs-6.7.ctime' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs (2023-10-30 09:47:13 -1000) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/overlayfs/vfs.git ovl-update-6.7 for you to fetch changes up to 24e16e385f2272b1a9df51337a5c32d28a29c7ad: ovl: add support for appending lowerdirs one by one (2023-10-31 00:13:02 +0200) ---------------------------------------------------------------- overlayfs update for 6.7 Contains the following patch sets: - Overlayfs aio cleanups and fixes [1] - Overlayfs lock ordering changes [2] - Add support for nesting overlayfs private xattrs [3] - Add new mount options for appending lowerdirs [4] [1] https://lore.kernel.org/r/20230912173653.3317828-1-amir73il@xxxxxxxxx/ [2] https://lore.kernel.org/r/20230816152334.924960-1-amir73il@xxxxxxxxx/ [3] https://lore.kernel.org/r/cover.1694512044.git.alexl@xxxxxxxxxx/ [4] https://lore.kernel.org/r/20231030120419.478228-1-amir73il@xxxxxxxxx/ ---------------------------------------------------------------- Alexander Larsson (4): ovl: Add OVL_XATTR_TRUSTED/USER_PREFIX_LEN macros ovl: Support escaped overlay.* xattrs ovl: Add an alternative type of whiteout ovl: Add documentation on nesting of overlayfs mounts Amir Goldstein (14): ovl: use simpler function to convert iocb to rw flags ovl: propagate IOCB_APPEND flag on writes to realfile ovl: punt write aio completion to workqueue ovl: protect copying of realinode attributes to ovl inode ovl: add helper ovl_file_modified() ovl: split ovl_want_write() into two helpers ovl: reorder ovl_want_write() after ovl_inode_lock() ovl: do not open/llseek lower file with upper sb_writers held ovl: do not encode lower fh with upper sb_writers held ovl: Move xattr support to new xattrs.c file ovl: remove unused code in lowerdir param parsing ovl: store and show the user provided lowerdir mount option ovl: refactor layer parsing helpers ovl: add support for appending lowerdirs one by one Documentation/filesystems/overlayfs.rst | 40 +++- fs/overlayfs/Makefile | 2 +- fs/overlayfs/copy_up.c | 142 +++++++++----- fs/overlayfs/dir.c | 64 +++---- fs/overlayfs/export.c | 7 +- fs/overlayfs/file.c | 88 ++++++--- fs/overlayfs/inode.c | 165 ++-------------- fs/overlayfs/namei.c | 52 ++++-- fs/overlayfs/overlayfs.h | 72 +++++-- fs/overlayfs/params.c | 322 +++++++++++++++++--------------- fs/overlayfs/params.h | 1 + fs/overlayfs/readdir.c | 27 ++- fs/overlayfs/super.c | 92 ++------- fs/overlayfs/util.c | 115 +++++++++++- fs/overlayfs/xattrs.c | 271 +++++++++++++++++++++++++++ fs/super.c | 1 + 16 files changed, 929 insertions(+), 532 deletions(-) create mode 100644 fs/overlayfs/xattrs.c
