2018-10-24cifs: allow calling SMB2_xxx_free(NULL)Ronnie Sahlberg1-7/+12
Change these free functions to allow passing NULL as the argument and treat it as a no-op just like free(NULL) would. Or, if rqst->rq_iov is NULL. The second scenario could happen for smb2_queryfs() if the call to SMB2_query_info_init() fails and we go to qfs_exit to clean up and free all resources. In that case we have not yet assigned rqst[2].rq_iov and thus the rq_iov dereference in SMB2_close_free() will cause a NULL pointer dereference.

2018-10-23smb3: show number of current open files in /proc/fs/cifs/StatsSteve French5-1/+13
To allow better debugging (for example applications with handle leaks, or complex reconnect scenarios) display the number of open files (on the client) and number of open server file handles for each tcon in /proc/fs/cifs/Stats. Note that open files on server is one larger than local due to handle caching (in this case of the root of the share). In this example there are two local open files, and three (two file and one directory handle) open on the server. Sample output: $ cat /proc/fs/cifs/Stats Resources in use CIFS Session: 1 Share (unique mount targets): 2 SMB Request/Response Buffer: 1 Pool size: 5 SMB Small Req/Resp Buffer: 1 Pool size: 30 Operations (MIDs): 0 0 session 0 share reconnects Total vfs operations: 36 maximum at one time: 2 1) \\localhost\test SMBs: 69 Bytes read: 27 Bytes written: 0 Open files: 2 total (local), 3 open on server TreeConnects: 1 total 0 failed TreeDisconnects: 0 total 0 failed Creates: 19 total 0 failed Closes: 16 total 0 failed ...

2018-10-23cifs: add support for ioctl on directoriesRonnie Sahlberg3-30/+102
We do not call cifs_open_file() for directories and thus we do not have a pSMBFile we can extract the FIDs from.

2018-10-23cifs: fallback to older infolevels on findfirst queryinfo retrySteve French1-30/+37
In cases where queryinfo fails, we have cases in cifs (vers=1.0) where with backupuid mounts we retry the query info with findfirst. This doesn't work to some NetApp servers which don't support WindowsXP (and later) infolevel 261 (SMB_FIND_FILE_ID_FULL_DIR_INFO) so in this case use other info levels (in this case it will usually be level 257, SMB_FIND_FILE_DIRECTORY_INFO).

2018-10-23smb3: do not attempt cifs operation in smb3 query info error pathSteve French1-1/+9
If backupuid mount option is sent, we can incorrectly retry (on access denied on query info) with a cifs (FindFirst) operation on an smb3 mount which causes the server to force the session close. We set backup intent on open so no need for this fallback.

2018-10-23CIFS: Print message when attempting a mountRodrigo Freire2-2/+7
Currently, no messages are printed when mounting a CIFS filesystem and no debug configuration is enabled. However, a CIFS mount information is valuable when troubleshooting and/or forensic analyzing a system and finding out if was a CIFS endpoint mount attempted. Other filesystems such as XFS, EXT* does issue a printk() when mounting their filesystems. A terse log message is printed only if cifsFYI is not enabled. Otherwise, the default full debug message is printed. In order to not clutter and classify correctly the event messages, these are logged as KERN_INFO level. Sample mount operations: [root@corinthians ~]# mount -o user=administrator //172.25.250.18/c$ /mnt (non-existent system) [root@corinthians ~]# mount -o user=administrator //172.25.250.19/c$ /mnt (Valid system) Kernel message log for the mount operations: [ 450.464543] CIFS: Attempting to mount //172.25.250.18/c$ [ 456.478186] CIFS VFS: Error connecting to socket.
