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.

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. Fix this by making the test as permissive as possible. Signed-off-by: NMichael S. Tsirkin <mst@dev.mellanox.co.il> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

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.

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>.

Code intended to check DMA status was checking DMA command register. Moreover firmware seems to "forget" to set DMA capable bit for the slave device (at least in RAID mode but without ITE RAID volumes) so check device ID for DMA capable bit when deciding whether to use DMA and remove DMA status check completely. Thanks to Pavol Simo for the bugreport and testing the initial fix. This change unfortunately still doesn't fix DMA in RAID mode (which works fine with IDE it821x) but Alan is working on the missing pieces (pata_it821x vs libata EH issues).
