[as posted on Feb 4, with accumulated acked-by/reviewed-by added; the original branch is also tagged (pull-fixes.pathwalk-rcu), the only difference is in the added lines in commit messages and resulting update of commit dates] The following changes since commit 6613476e225e090cc9aad49be7fa504e290dd33d: Linux 6.8-rc1 (2024-01-21 14:11:32 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git tags/pull-fixes.pathwalk-rcu-2 for you to fetch changes up to 9fa8e282c2bfe93338e81a620a49f5903a745231: ext4_get_link(): fix breakage in RCU mode (2024-02-25 02:10:32 -0500) ---------------------------------------------------------------- We still have some races in filesystem methods when exposed to RCU pathwalk. This series is a result of code audit (the second round of it) and it should deal with most of that stuff. Exceptions: ntfs3 ->d_hash()/->d_compare() and ceph_d_revalidate(). Up to maintainers (a note for NTFS folks - when documentation says that a method may not block, it *does* imply that blocking allocations are to be avoided. Really). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> ---------------------------------------------------------------- Al Viro (13): fs/super.c: don't drop ->s_user_ns until we free struct super_block itself rcu pathwalk: prevent bogus hard errors from may_lookup() affs: free affs_sb_info with kfree_rcu() exfat: move freeing sbi, upcase table and dropping nls into rcu-delayed helper hfsplus: switch to rcu-delayed unloading of nls and freeing ->s_fs_info afs: fix __afs_break_callback() / afs_drop_open_mmap() race nfs: make nfs_set_verifier() safe for use in RCU pathwalk nfs: fix UAF on pathwalk running into umount procfs: move dropping pde and pid from ->evict_inode() to ->free_inode() procfs: make freeing proc_fs_info rcu-delayed fuse: fix UAF in rcu pathwalks cifs_get_link(): bail out in unsafe case ext4_get_link(): fix breakage in RCU mode fs/affs/affs.h | 1 + fs/affs/super.c | 2 +- fs/afs/file.c | 8 ++++++-- fs/exfat/exfat_fs.h | 1 + fs/exfat/nls.c | 14 ++++---------- fs/exfat/super.c | 20 +++++++++++--------- fs/ext4/symlink.c | 8 +++++--- fs/fuse/cuse.c | 3 +-- fs/fuse/fuse_i.h | 1 + fs/fuse/inode.c | 15 +++++++++++---- fs/hfsplus/hfsplus_fs.h | 1 + fs/hfsplus/super.c | 12 +++++++++--- fs/namei.c | 6 +++++- fs/nfs/client.c | 13 ++++++++++--- fs/nfs/dir.c | 4 ++-- fs/proc/base.c | 2 -- fs/proc/inode.c | 19 ++++++++----------- fs/proc/root.c | 2 +- fs/smb/client/cifsfs.c | 3 +++ fs/super.c | 13 ++++--------- include/linux/nfs_fs_sb.h | 2 ++ include/linux/proc_fs.h | 1 + 22 files changed, 88 insertions(+), 63 deletions(-)
