2007-10-04[CIFS] Fix cifsd so shuts down when signing fails during mountSteve French
Fixes two problems: 1) we dropped down to negotiating lanman if we did not recognize the mechanism (krb5 e.g.) 2) we did not stop cifsd (thus will fail when doing rmod cifs with slab free errors) when we fail tcon but have a bad session (which is the case in which signing is required but we don't allow signing on the client) It also turns on extended security flag in the header when passing "sec=krb5" on mount command (although kerberos support is not done of course) Acked-by: Jeff Layton <jlayton@redhat.com> CC: Shaggy <shaggy@us.ibm.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

2007-10-02[CIFS] Reduce chance of list corruption in find_writable_fileSteve French
When find_writable_file is racing with close and the session to the server goes down, Shaggy noticed that there was a chance that an open file in the list of files off the inode could have been freed by close since cifs_reconnect can block (the spinlock thus not held). This means that we have to start over at the beginning of the list in some cases. There is a 2nd change that needs to be made later (pointed out by Jeremy Allison and Shaggy) in order to prevent cifs_close ever freeing the cifs per file info when a write is pending. Although we delay close from freeing this memory for sufficiently long for all known cases, ultimately on a very, very slow write overlapping a close pending we need to allow close to return (without freeing the cifs file info) and defer freeing the memory to be the responsibility of the (sloooow) write thread (presumably have to look at every place wrtPending is decremented - and add a flag for deferred free for after wrtPending goes to zero).

2007-09-20[CIFS] Add warning message when broken server fails SetFSInfo callSteve French
A reasonably common NAS server returns an error on the SetFSInfo of the Unix capabilities. Log a message for this alerting the user that the server may have problems with the Unix extensions, and telling them what they can do to workaround it. Unfortunately the server does not return other clues that we could easily use to turn the Unix Extension support off automatically in this case (since they claim to support it).

2007-09-16[CIFS] fix small memory leak in an error path in new posix mkdirSteve French
There is a small memory leak in fs/cifs/inode.c::cifs_mkdir(). Storage for 'pInfo' is allocated with kzalloc(), but if the call to CIFSPOSIXCreate(...) happens to return 0 and pInfo->Type == -1, then we'll jump to the 'mkdir_get_info' label without freeing the storage allocated for 'pInfo'. This patch adds a kfree() call to free the storage just before jumping to the label, thus getting rid of the leak.

2007-08-30[CIFS] fix for incorrect session reconnectsSteve French
cifs reconnect could end up happening incorrectly due to the small initial tcp recvmsg response. When the socket was within three bytes of being full and the recvmsg returned only 1 to 3 bytes of the initial 4 byte read of the RFC1001 length field. Fortunately this seems to be less common on more current kernels, but this fixes it so cifs tries to retrieve all 4 bytes of the initial tcp read.

2007-08-24[CIFS] Byte range unlock request to non-Unix server can unlock too muchJeff Layton
On a mount without posix extensions enabled, when an unlock request is made, the client can release more than is intended. To reproduce, on a CIFS mount without posix extensions enabled: 1) open file 2) do fcntl lock: start=0 len=1 3) do fcntl lock: start=2 len=1 4) do fcntl unlock: start=0 len=1 ...on the unlock call the client sends an unlock request to the server for both locks.

2007-08-20Revert "USB: EHCI cpufreq fix"Linus Torvalds
This reverts commit 196705c9bbc03540429b0f7cf9ee35c2f928a534. It was reported to cause a regression by Daniel Exner, and Arjan van de Ven points out that we actually already have infrastructure in place for setting limits on acceptable DMA latency that would be the much more correct fix for the problem with some Broadcom EHCI controllers. Fixed up trivial conflicts due to the changes to support big-endian host controller descriptors in drivers/usb/host/{ehci-sched.c,ehci.h}.

2007-08-20dio: zero struct dio with kzalloc instead of manuallyZach Brown
This patch uses kzalloc to zero all of struct dio rather than manually trying to track which fields we rely on being zero. It passed aio+dio stress testing and some bug regression testing on ext3. This patch was introduced by Linus in the conversation that lead up to Badari's minimal fix to manually zero .map_bh.b_state in commit: 6a648fa72161d1f6468dabd96c5d3c0db04f598a It makes the code a bit smaller. Maybe a couple fewer cachelines to load, if we're lucky: text data bss dec hex filename 3285925 568506 1304616 5159047 4eb887 vmlinux 3285797 568506 1304616 5158919 4eb807 vmlinux.patched I was unable to measure a stable difference in the number of cpu cycles spent in blockdev_direct_IO() when pushing aio+dio 256K reads at ~340MB/s. So the resulting intent of the patch isn't a performance gain but to avoid exposing ourselves to the risk of finding another field like .map_bh.b_state where we rely on zeroing but don't enforce it in the code.
