Thank you!
Hi Linus, Please pull this first batch of new changes for 5.7. There's a lot going on this cycle with cleanups in the log code, the btree code, and the xattr code. We're tightening of metadata validation and online fsck checking, and introducing a common btree rebuilding library so that we can refactor xfs_repair and introduce online repair in a future cycle. We also fixed a few visible bugs -- most notably there's one in getdents that we introduced in 5.6; and a fix for hangs when disabling quotas. This series has been running fstests & other QA in the background for over a week and looks good so far. I just did a test merge and it seems to go in cleanly, so please let me know if you encounter any surprises. I anticipate sending you a second pull request next week. That batch will change how xfs interacts with memory reclaim; how the log batches and throttles log items; how hard writes near ENOSPC will try to squeeze more space out of the filesystem; and hopefully fix the last of the umount hangs after a catastrophic failure. That should ease a lot of problems when running at the limits, but for now I'm leaving that in for-next for another week to make sure we got all the subtleties right. --D The following changes since commit 98d54f81e36ba3bf92172791eba5ca5bd813989b: Linux 5.6-rc4 (2020-03-01 16:38:46 -0600) are available in the Git repository at: git://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git tags/xfs-5.7-merge-8 for you to fetch changes up to 27fb5a72f50aa770dd38b0478c07acacef97e3e7: xfs: prohibit fs freezing when using empty transactions (2020-03-26 08:19:24 -0700) ---------------------------------------------------------------- New code for 5.7: - Fix a hard to trigger race between iclog error checking and log shutdown. - Strengthen the AGF verifier. - Ratelimit some of the more spammy error messages. - Remove the icdinode uid/gid members and just use the ones in the vfs inode. - Hold ILOCK across insert/collapse range. - Clean up the extended attribute interfaces. - Clean up the attr flags mess. - Restore PF_MEMALLOC after exiting xfsaild thread to avoid triggering warnings in the process accounting code. - Remove the flexibly-sized array from struct xfs_agfl to eliminate compiler warnings about unaligned pointers and packed structures. - Various macro and typedef removals. - Stale metadata buffers if we decide they're corrupt outside of a verifier. - Check directory data/block/free block owners. - Fix a UAF when aborting inactivation of a corrupt xattr fork. - Teach online scrub to report failed directory and attr name lookups as a metadata corruption instead of a runtime error. - Avoid potential buffer overflows in sysfs files by using scnprintf. - Fix a regression in getdents lookups due to a mistake in pointer arithmetic. - Refactor btree cursor private data structures to use anonymous unions. - Cleanups in the log unmounting code. - Fix a potential mishandling of ENOMEM errors on multi-block directory buffer lookups. - Fix an incorrect test in the block allocation code. - Cleanups and name prefix shortening in the scrub code. - Introduce btree bulk loading code for online repair and scrub. - Fix a quotaoff log item leak (and hang) when the fs goes down midway through a quotaoff operation. - Remove di_version from the incore inode. - Refactor some of the log shutdown checking code. - Record the forcing of the log unmount records in the log force counters. - Fix a longstanding bug where quotacheck would purge the administrator's default quota grace interval and warning limits. - Reduce memory usage when scrubbing directory and xattr trees. - Don't let fsfreeze race with GETFSMAP or online scrub. - Handle bio_add_page failures more gracefully in xlog_write_iclog. ---------------------------------------------------------------- Brian Foster (7): xfs: fix iclog release error check race with shutdown xfs: open code insert range extent split helper xfs: rework insert range into an atomic operation xfs: rework collapse range into an atomic operation xfs: factor out quotaoff intent AIL removal and memory free xfs: fix unmount hang and memory leak on shutdown during quotaoff xfs: shutdown on failure to add page to log bio Christoph Hellwig (60): xfs: ensure that the inode uid/gid match values match the icdinode ones xfs: remove the icdinode di_uid/di_gid members xfs: remove the kuid/kgid conversion wrappers xfs: ratelimit xfs_buf_ioerror_alert messages xfs: ratelimit xfs_discard_page messages xfs: reject invalid flags combinations in XFS_IOC_ATTRLIST_BY_HANDLE xfs: remove the ATTR_INCOMPLETE flag xfs: merge xfs_attr_remove into xfs_attr_set xfs: merge xfs_attrmulti_attr_remove into xfs_attrmulti_attr_set xfs: use strndup_user in XFS_IOC_ATTRMULTI_BY_HANDLE xfs: factor out a helper for a single XFS_IOC_ATTRMULTI_BY_HANDLE op xfs: remove the name == NULL check from xfs_attr_args_init xfs: remove the MAXNAMELEN check from xfs_attr_args_init xfs: turn xfs_da_args.value into a void pointer xfs: pass an initialized xfs_da_args structure to xfs_attr_set xfs: pass an initialized xfs_da_args to xfs_attr_get xfs: remove the xfs_inode argument to xfs_attr_get_ilocked xfs: remove ATTR_KERNOVAL xfs: remove ATTR_ALLOC and XFS_DA_OP_ALLOCVAL xfs: replace ATTR_KERNOTIME with XFS_DA_OP_NOTIME xfs: factor out a xfs_attr_match helper xfs: cleanup struct xfs_attr_list_context xfs: remove the unused ATTR_ENTRY macro xfs: open code ATTR_ENTSIZE xfs: move the legacy xfs_attr_list to xfs_ioctl.c xfs: rename xfs_attr_list_int to xfs_attr_list xfs: lift common checks into xfs_ioc_attr_list xfs: lift buffer allocation into xfs_ioc_attr_list xfs: lift cursor copy in/out into xfs_ioc_attr_list xfs: improve xfs_forget_acl xfs: clean up the ATTR_REPLACE checks xfs: clean up the attr flag confusion xfs: remove XFS_DA_OP_INCOMPLETE xfs: embedded the attrlist cursor into struct xfs_attr_list_context xfs: clean up bufsize alignment in xfs_ioc_attr_list xfs: only allocate the buffer size actually needed in __xfs_set_acl xfs: switch xfs_attrmulti_attr_get to lazy attr buffer allocation xfs: remove the agfl_bno member from struct xfs_agfl xfs: remove the xfs_agfl_t typedef xfs: remove XFS_BUF_TO_AGI xfs: remove XFS_BUF_TO_AGF xfs: remove XFS_BUF_TO_SBP xfs: mark XLOG_FORCED_SHUTDOWN as unlikely xfs: remove the unused XLOG_UNMOUNT_REC_TYPE define xfs: remove the unused return value from xfs_log_unmount_write xfs: remove dead code from xfs_log_unmount_write xfs: cleanup xfs_log_unmount_write xfs: add a new xfs_sb_version_has_v3inode helper xfs: only check the superblock version for dinode size calculation xfs: simplify di_flags2 inheritance in xfs_ialloc xfs: simplify a check in xfs_ioctl_setattr_check_cowextsize xfs: remove the di_version field from struct icdinode xfs: merge xlog_cil_push into xlog_cil_push_work xfs: factor out a xlog_wait_on_iclog helper xfs: simplify the xfs_log_release_iclog calling convention xfs: simplify log shutdown checking in xfs_log_release_iclog xfs: remove the aborted parameter to xlog_state_done_syncing xfs: refactor xlog_state_clean_iclog xfs: move the ioerror check out of xlog_state_clean_iclog xfs: remove xlog_state_want_sync Darrick J.
