cifs: fix potential race with cifsd thread

2022-04-04T17:01:22+00:00

To avoid racing with demultiplex thread while it is handling data on socket, use cifs_signal_cifsd_for_reconnect() helper for marking current server to reconnect and let the demultiplex thread handle the rest. Fixes: dca65818c80c ("cifs: use a different reconnect helper for non-cifsd threads") Reviewed-by: Enzo Matsumiya Reviewed-by: Shyam Prasad N Signed-off-by: Paulo Alcantara (SUSE) Signed-off-by: Steve French

cifs: cifs_ses_mark_for_reconnect should also update reconnect bits

2022-01-19T17:10:58+00:00

Recent restructuring of cifs_reconnect introduced a helper func named cifs_ses_mark_for_reconnect, which updates the state of tcp session for all the channels of a session for reconnect. However, this does not update the session state and chans_need_reconnect bitmask. This change fixes that. Also, cifs_mark_tcp_sess_for_reconnect should mark set the bitmask for all channels when the whole session is marked for reconnect. Fixed that here too.

cifs: take cifs_tcp_ses_lock for status checks

2022-01-08T02:07:07+00:00

While checking/updating status for tcp ses, smb ses or tcon, we take GlobalMid_Lock. This doesn't make any sense. Replaced it with cifs_tcp_ses_lock. Ideally, we should take a spin lock per struct. But since tcp ses, smb ses and tcon objects won't add up to a lot, I think there should not be too much contention. Also, in few other places, these are checked without locking. Added locking for these. Signed-off-by: Shyam Prasad N Signed-off-by: Steve French

cifs: remove pathname for file from SPDX header

2021-09-13T19:51:10+00:00

checkpatch complains about source files with filenames (e.g. in these cases just below the SPDX header in comments at the top of various files in fs/cifs). It also is helpful to change this now so will be less confusing when the parent directory is renamed e.g. from fs/cifs to fs/smb_client (or fs/smbfs) Reviewed-by: Ronnie Sahlberg Signed-off-by: Steve French

cifs`: handle ERRBaduid for SMB1

2020-08-02T23:00:25+00:00

If server returns ERRBaduid but does not reset transport connection, we'll keep sending command with a non-valid UID for the server as long as transport is healthy, without actually recovering. This have been observed on the field. This patch adds ERRBaduid handling so that we set CifsNeedReconnect. map_and_check_smb_error() can be modified to extend use cases.

cifs: Standardize logging output

2020-06-01T05:10:18+00:00

Use pr_fmt to standardize all logging for fs/cifs. Some logging output had no CIFS: specific prefix. Now all output has one of three prefixes: o CIFS: o CIFS: VFS: o Root-CIFS: Miscellanea: o Convert printks to pr_ o Neaten macro definitions o Remove embedded CIFS: prefixes from formats o Convert "illegal" to "invalid" o Coalesce formats o Add missing '\n' format terminations o Consolidate multiple cifs_dbg continuations into single calls o More consistent use of upper case first word output logging o Multiline statement argument alignment and wrapping Signed-off-by: Joe Perches Signed-off-by: Steve French

fs: cifs: Initialize filesystem timestamp ranges

2019-08-30T14:27:18+00:00

Fill in the appropriate limits to avoid inconsistencies in the vfs cached inode times when timestamps are outside the permitted range. Also fixed cnvrtDosUnixTm calculations to avoid int overflow while computing maximum date.
