| * [CIFS] Remove redundant testJulia Lawall2008-12-261-4/+0
| | | | | | | | | | | | | | | | | | | | | | In fs/cifs/cifssmb.c, pLockData is tested for being NULL at the beginning of the function, and not reassigned subsequently.

| * [CIFS] make sure that DFS pathnames are properly formedSteve French2008-12-262-13/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The paths in a DFS request are supposed to only have a single preceding backslash, but we are sending them with a double backslash. This is exposing a bug in Windows where it also sends a path in the response that has a double backslash. The existing code that builds the mount option string however expects a double backslash prefix in a couple of places when it tries to use the path returned by build_path_from_dentry. Fix compose_mount_options to expect properly formed DFS paths (single backslash at front). Also clean up error handling in that function. There was a possible NULL pointer dereference and situations where a partially built option string would be returned. Tested against Samba 3.0.28-ish server and Samba 3.3 and Win2k8.

| * cifs: fix wait_for_response to time out sleeping processes correctlyJeff Layton2008-12-261-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cifs: fix wait_for_response to time out sleeping processes correctly The current scheme that CIFS uses to sleep and wait for a response is not quite what we want. After sending a request, wait_for_response puts the task to sleep with wait_event(). One of the conditions for wait_event is a timeout (using time_after()). The problem with this is that there is no guarantee that the process will ever be woken back up. If the server stops sending data, then cifs_demultiplex_thread will leave its response queue sleeping. I think the only thing that saves us here is the fact that cifs_dnotify_thread periodically (every 15s) wakes up sleeping processes on all response_q's that have calls in flight. This makes for unnecessary wakeups of some processes. It also means large variability in the timeouts since they're all woken up at once. Instead of this, put the tasks to sleep with wait_event_timeout. This makes them wake up on their own if they time out. With this change, cifs_dnotify_thread should no longer be needed. I've been testing this in conjunction with some other patches that I'm working on. It doesn't seem to affect performance at all with with heavy I/O. Identical iozone -ac runs complete in almost exactly the same time (<1% difference in times). Thanks to Wasrshi Nimara for initially pointing this out. Wasrshi, it would be nice to know whether this patch also helps your testcase.

| * [CIFS] Can not mount with prefixpath if root directory of share is inaccessibleSteve French2008-12-262-6/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Windows allows you to deny access to the top of a share, but permit access to a directory lower in the path. With the prefixpath feature of cifs (ie mounting \\server\share\directory\subdirectory\etc.) this should have worked if the user specified a prefixpath which put the root of the mount at a directory to which he had access, but we still were doing a lookup on the root of the share (null path) when we should have been doing it on the prefixpath subdirectory.

| * [CIFS] add mount option to send mandatory rather than advisory locksSteve French2008-12-266-16/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some applications/subsystems require mandatory byte range locks (as is used for Windows/DOS/OS2 etc). Sending advisory (posix style) byte range lock requests (instead of mandatory byte range locks) can lead to problems for these applications (which expect that other clients be prevented from writing to portions of the file which they have locked and are updating). This mount option allows mounting cifs with the new mount option "forcemand" (or "forcemandatorylock") in order to have the cifs client use mandatory byte range locks (ie SMB/CIFS/Windows/NTFS style locks) rather than posix byte range lock requests, even if the server would support posix byte range lock requests. This has no effect if the server does not support the CIFS Unix Extensions (since posix style locks require support for the CIFS Unix Extensions), but for mounts to Samba servers this can be helpful for Wine and applications that require mandatory byte range locks.

Finally, drop the unicode_server_Name field from TCP_Server_Info since it's not used. We can add it back later if needed, but for now it just wastes memory.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | arch_setup_additional_pages currently gets two arguments, the binary format descripton and an indication if the process uses an executable stack or not. The second argument is not used by anybody, it could be removed without replacement. What actually does make sense is to pass an indication if the process uses the elf interpreter or not. The glibc code will not use anything from the vdso if the process does not use the dynamic linker, so for statically linked binaries the architecture backend can choose not to map the vdso.
