2014-08-25CIFS: Fix wrong filename length for SMB2Pavel Shilovsky1-1/+1
The existing code uses the old MAX_NAME constant. This causes XFS test generic/013 to fail. Fix it by replacing MAX_NAME with PATH_MAX that SMB1 uses. Also remove an unused MAX_NAME constant definition. Cc: <stable@vger.kernel.org> # v3.7+ Signed-off-by: Pavel Shilovsky <pshilovsky@samba.org> Signed-off-by: Steve French <smfrench@gmail.com>

2013-11-11CIFS: Fix symbolic links usagePavel Shilovsky1-4/+12
Now we treat any reparse point as a symbolic link and map it to a Unix one that is not true in a common case due to many reparse point types supported by SMB servers. Distinguish reparse point types into two groups: 1) that can be accessed directly through a reparse point (junctions, deduplicated files, NFS symlinks); 2) that need to be processed manually (Windows symbolic links, DFS); and map only Windows symbolic links to Unix ones.

2013-07-10CIFS: Reconnect durable handles for SMB2Pavel Shilovsky1-0/+1
On reconnects, we need to reopen file and then obtain all byte-range locks held by the client. SMB2 protocol provides feature to make this process atomic by reconnecting to the same file handle with all it's byte-range locks. This patch adds this capability for SMB2 shares.

2013-05-04[CIFS] cifs: Rename cERROR and cFYI to cifs_dbgJoe Perches1-1/+1
It's not obvious from reading the macro names that these macros are for debugging. Convert the names to a single more typical kernel style cifs_dbg macro. cERROR(1, ...) -> cifs_dbg(VFS, ...) cFYI(1, ...) -> cifs_dbg(FYI, ...) cFYI(DBG2, ...) -> cifs_dbg(NOISY, ...) Move the terminating format newline from the macro to the call site. Add CONFIG_CIFS_DEBUG function cifs_vfs_err to emit the "CIFS VFS: " prefix for VFS messages. Size is reduced ~ 1% when CONFIG_CIFS_DEBUG is set (default y) $ size fs/cifs/cifs.ko* text data bss dec hex filename 265245 2525 132 267902 4167e fs/cifs/cifs.ko.new 268359 2525 132 271016 422a8 fs/cifs/cifs.ko.old Other miscellaneous changes around these conversions: o Miscellaneous typo fixes o Add terminating \n's to almost all formats and remove them from the macros to be more kernel style like. A few formats previously had defective \n's o Remove unnecessary OOM messages as kmalloc() calls dump_stack o Coalesce formats to make grep easier, added missing spaces when coalescing formats o Use %s, __func__ instead of embedded function name o Removed unnecessary "cifs: " prefixes o Convert kzalloc with multiply to kcalloc o Remove unused cifswarn macro Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <smfrench@gmail.com>
