2014-10-02CIFS: Fix readpages retrying on reconnectsPavel Shilovsky1-7/+1
If we got a reconnect error from async readv we re-add pages back to page_list and continue loop. That is wrong because these pages have been already added to the pagecache but page_list has pages that have not been added to the pagecache yet. This ends up with a general protection fault in put_pages after readpages. Fix it by not retrying the read of these pages and falling back to readpage instead.

2014-10-02Fix problem recognizing symlinksSteve French2-1/+3
Changeset eb85d94bd introduced a problem where if a cifs open fails during query info of a file we will still try to close the file (happens with certain types of reparse points) even though the file handle is not valid. In addition for SMB2/SMB3 we were not mapping the return code returned by Windows when trying to open a file (like a Windows NFS symlink) which is a reparse point.

2014-08-22CIFS: Fix directory rename errorPavel Shilovsky1-1/+4
CIFS servers process nlink counts differently for files and directories. In cifs_rename() if we the request fails on the existing target, we try to remove it through cifs_unlink() but this is not what we want to do for directories. As the result the following sequence of commands mkdir {1,2}; mv -T 1 2; rmdir {1,2}; mkdir {1,2}; echo foo > 2/bar and XFS test generic/023 fail with -ENOENT error. That's why the second mkdir reuses the existing inode (target inode of the mv -T command) with S_DEAD flag. Fix this by checking whether the target is directory or not and calling cifs_rmdir() rather than cifs_unlink() for directories.

SMB2 servers indicates the end of a directory search with STATUS_NO_MORE_FILE error code that is not processed now. This causes generic/257 xfstest to fail. Fix this by triggering the end of search by this error code in SMB2_query_directory. Also when negotiating CIFS protocol we tell the server to close the search automatically at the end and there is no need to do it itself. In the case of SMB2 protocol, we need to close it explicitly - separate close directory checks for different protocols.

2014-08-15[CIFS] Workaround MacOS server problem with SMB2.1 writeSteve French1-1/+16
response Writes fail to Mac servers with SMB2.1 mounts (works with cifs though) due to them sending an incorrect RFC1001 length for the SMB2.1 Write response. Workaround this problem. MacOS server sends a write response with 3 bytes of pad beyond the end of the SMB itself. The RFC1001 length is 3 bytes more than the sum of the SMB2.1 header length + the write reponse. Incorporate feedback from Jeff and JRA to allow servers to send a tcp frame that is even more than three bytes too long (ie much longer than the SMB2/SMB3 request that it contains) but we do log it once now. In the earlier version of the patch I had limited how far off the length field could be before we fail the request. Signed-off-by: Steve French <smfrench@gmail.com>

2014-08-13Add sparse file support to SMB2/SMB3 mountsSteve French3-1/+47
Many Linux filesystes make a file "sparse" when extending a file with ftruncate. This does work for CIFS to Samba (only) but not for SMB2/SMB3 (to Samba or Windows) since there is a "set sparse" fsctl which is supposed to be sent to mark a file as sparse. This patch marks a file as sparse by sending this simple set sparse fsctl if it is extended more than 2 pages. It has been tested to Windows 8.1, Samba and various SMB2/SMB3 servers which do support setting sparse (and MacOS which does not appear to support the fsctl yet). If a server share does not support setting a file as sparse, then we do not retry setting sparse on that share. The disk space savings for sparse files can be quite large (even more significant on Windows servers than Samba).
