2021-11-06gfs2: release iopen glock early in evictBob Peterson
Before this patch, evict would clear the iopen glock's gl_object after releasing the inode glock. In the meantime, another process could reuse the same block and thus glocks for a new inode. It would lock the inode glock (exclusively), and then the iopen glock (shared). The shared locking mode doesn't provide any ordering against the evict, so by the time the iopen glock is reused, evict may not have gotten to setting gl_object to NULL. Fix that by releasing the iopen glock before the inode glock in gfs2_evict_inode. Signed-off-by: Bob Peterson <rpeterso@redhat.com>gl_object Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
2021-11-05smb3: add dynamic trace points for socket connectionSteve French
In debugging user problems with ip address/DNS issues with smb3 mounts, we sometimes needed additional info on the hostname and ip address. Add two tracepoints, one to show socket connection success and one for failures to connect to the socket. Sample output: mount.cifs-14551 [005] ..... 7636.547906: smb3_connect_done: conn_id=0x1 server=localhost addr=127.0.0.1:445 mount.cifs-14558 [004] ..... 7642.405413: smb3_connect_done: conn_id=0x2 server=smfrench.file.core.windows.net addr=52.239.158.232:445 mount.cifs-14741 [005] ..... 7818.490716: smb3_connect_done: conn_id=0x3 server=::1 addr=[::1]:445/0%0 mount.cifs-14810 [000] ..... 7966.380337: smb3_connect_err: rc=-101 conn_id=0x4 server=::2 addr=[::2]:445/0%0 mount.cifs-14810 [000] ..... 7966.380356: smb3_connect_err: rc=-101 conn_id=0x4 server=::2 addr=[::2]:139/0%0 mount.cifs-14818 [003] ..... 7986.771992: smb3_connect_done: conn_id=0x5 server=127.0.0.9 addr=127.0.0.9:445 mount.cifs-14825 [008] ..... 8008.178109: smb3_connect_err: rc=-115 conn_id=0x6 server=124.23.0.9 addr=124.23.0.9:445 mount.cifs-14825 [008] ..... 8013.298085: smb3_connect_err: rc=-115 conn_id=0x6 server=124.23.0.9 addr=124.23.0.9:139 cifsd-14553 [006] ..... 8036.735615: smb3_reconnect: conn_id=0x1 server=localhost current_mid=32 cifsd-14743 [010] ..... 8036.735644: smb3_reconnect: conn_id=0x3 server=::1 current_mid=29 cifsd-14743 [010] ..... 8039.921740: smb3_connect_err: rc=-111 conn_id=0x3 server=::1 addr=[::1]:445/0%0 cifsd-14553 [008] ..... 8042.993894: smb3_connect_err: rc=-111 conn_id=0x1 server=localhost addr=127.0.0.1:445 cifsd-14743 [010] ..... 8042.993894: smb3_connect_err: rc=-111 conn_id=0x3 server=::1 addr=[::1]:445/0%0 cifsd-14553 [008] ..... 8046.065824: smb3_connect_err: rc=-111 conn_id=0x1 server=localhost addr=127.0.0.1:445 cifsd-14743 [010] ..... 8046.065824: smb3_connect_err: rc=-111 conn_id=0x3 server=::1 addr=[::1]:445/0%0 cifsd-14553 [008] ..... 8049.137796: smb3_connect_done: conn_id=0x1 server=localhost addr=127.0.0.1:445 cifsd-14743 [010] ..... 8049.137796: smb3_connect_done: conn_id=0x3 server=::1 addr=[::1]:445/0%0 Reviewed-by: Paulo Alcantara (SUSE) <pc@cjr.nz> Signed-off-by: Steve French <stfrench@microsoft.com>

2021-11-04ext4: fix error code saved on super block during file system abortGabriel Krisman Bertazi
ext4_abort will eventually call ext4_errno_to_code, which translates the errno to an EXT4_ERR specific error. This means that ext4_abort expects an errno. By using EXT4_ERR_ here, it gets misinterpreted (as an errno), and ends up saving EXT4_ERR_EBUSY on the superblock during an abort, which makes no sense. ESHUTDOWN will get properly translated to EXT4_ERR_SHUTDOWN, so use that instead.

2021-11-04ext4: prevent getting empty inode bufferZhang Yi
In ext4_get_inode_loc(), we may skip IO and get an zero && uptodate inode buffer when the inode monopolize an inode block for performance reason. For most cases, ext4_mark_iloc_dirty() will fill the inode buffer to make it fine, but we could miss this call if something bad happened. Finally, __ext4_get_inode_loc_noinmem() may probably get an empty inode buffer and trigger ext4 error. For example, if we remove a nonexistent xattr on inode A, ext4_xattr_set_handle() will return ENODATA before invoking ext4_mark_iloc_dirty(), it will left an uptodate but zero buffer. We will get checksum error message in ext4_iget() when getting inode again. EXT4-fs error (device sda): ext4_lookup:1784: inode #131074: comm cat: iget: checksum invalid Even worse, if we allocate another inode B at the same inode block, it will corrupt the inode A on disk when write back inode B. So this patch initialize the inode buffer by filling the in-mem inode contents if we skip read I/O, ensure that the buffer is really uptodate.

2021-11-04ext4: prevent partial update of the extent blocksZhang Yi
