2007-07-16[CIFS] use simple_prepare_write to zero page dataNate1-8/+1
It's common for file systems to need to zero data on either side of a write, if a page is not Uptodate during prepare_write. It just so happens that simple_prepare_write() in libfs.c does exactly that, so we can avoid duplication and just call that function to zero page data.

In the cleanup phase of the dbench test, we were noticing sharing violation followed by failed directory removals when dbench did not close the test files before the cleanup phase started. Using the new POSIX unlink, which Samba has supported for a few months, avoids this. Signed-off-by: Steve French <sfrench@us.ibm.com>

This should be the last big batch of whitespace/formatting fixes. checkpatch warnings for the cifs directory are down about 90% and many of the remaining ones are harder to remove or make the code harder to read. Signed-off-by: Steve French <sfrench@us.ibm.com>
2007-07-11[CIFS] Fix oops in cifs_create when nfsd server exports cifs mountSteve French6-14/+33
nfsd is passing null nameidata (probably the only one doing that) on call to create - cifs was missing one check for this. Note that running nfsd over a cifs mount requires specifying fsid on the nfs exports entry and requires mounting cifs with serverino mount option. Signed-off-by: Steve French <sfrench@us.ibm.com>

2007-07-06[CIFS] Mount should fail if server signing off but client mount option ↵Jeff2-1/+3
requires it Currently, if mount with a signing-enabled sec= option (e.g. sec=ntlmi), the kernel does a warning printk if the server doesn't support signing, and then proceeds without signatures. This is probably OK for people that think to look at the ring buffer, but seems wrong to me. If someone explicitly requests signing, we should error out if that request can't be satisfied. They can then reattempt the mount without signing if that's ok. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

2007-06-22i386: Make CMPXCHG64 only dependent on PAEAndi Kleen2-2/+2
It is only used for PAE kernels in set_64bit. The problem is that due to a old Windows bug many CPUs need magic MSRs to enable CMPXCHG64, and we can't do that nicely early enough before it is potentially used. But since we only need it in PAE kernels so only force the checking for CMPXCHG65 with PAE.

2007-06-21posix-timers: Prevent softirq starvation by small intervals and SIG_IGNThomas Gleixner1-2/+33
posix-timers which deliver an ignored signal are currently rearmed in the timer softirq: This is necessary because the timer needs to be delivered again when SIG_IGN is removed. This is not a problem, when the interval is reasonable. With high resolution timers enabled one might arm a posix timer with a very small interval and ignore the signal. This might lead to a softirq starvation when the interval is so small that the timer is requeued onto the softirq pending list right away. This problem was pointed out by Jan Kiszka. Thanks Jan ! The correct solution would be to stop the timer, when the signal is ignored and rearm it when SIG_IGN is removed. Unfortunately this requires modification in sigaction and involves non trivial sighand locking. It's too late in the release cycle for such a change. For now we just keep the timer running and enforce that the timer only fires every jiffie. This does not break anything as we keep the overrun counter correct. It adds a little inaccuracy to the timer_gettime() interface, but... The more complex change is necessary anyway to fix another short coming of the current implementation, which I discovered while looking at this problem: A pending signal is discarded when SIG_IGN is set. In case that a posixtimer signal is pending then it is discarded as well, but when SIG_IGN is removed later nothing rearms the timer. This is not new, it's that way since posix timers have been merged. So nothing to worry about right now. I have a working solution to fix all of this, but the impact is too large for both stable and 2.6.22. I'm going to send it out for review in the next days. This should go into 2.6.21.stable as well.

2007-06-21IPoIB/cm: Fix interoperability when MTU doesn't matchMichael S. Tsirkin1-3/+3
IPoIB connected mode currently rejects a connection request unless the supported MTU is >= the local netdevice MTU. This breaks interoperability with implementations that might have tweaked IPOIB_CM_MTU, and there's real no longer a reason to do so: this test is just a leftover from when we did not tweak MTU per-connection.

2007-06-21IPoIB/cm: Initialize RX before moving QP to RTRMichael S. Tsirkin1-12/+17
Fix a crasher bug in IPoIB CM: once a QP is in the RTR state, a receive completion (or even an asynchronous error) might be observed on this QP, so we have to initialize all of our receive data structures before moving to the RTR state. As an optimization (since modify_qp might take a long time), the jiffies update done when moving RX to the passive_ids list is also left in place to reduce the chance of the RX being misdetected as stale.

2007-06-21IB/umem: Fix possible hang on process exitRoland Dreier1-7/+9
If ib_umem_release() is called after ib_uverbs_close() sets context->closing, then a process can get stuck in a D state, because the code boils down to if (down_write_trylock(&mm->mmap_sem)) down_write(&mm->mmap_sem); which is obviously a stupid instant deadlock. Fix the code so that we only try to take the lock once. This bug was introduced in commit f7c6a7b5 ("IB/uverbs: Export ib_umem_get()/ib_umem_release() to modules") which fortunately never made it into a release, and was reported by Pete Wyckoff <pw@osc.edu>.
