There is no realistic situation to change helper (Who wants IRC helper to track FTP traffic ?). Moreover, if we want to do that, we need to fix race issue by nfctnetlink and running helper. That will add overhead to packet processing. It wouldn't pay. So this rejects the request to change helper. The requests to add or remove helper are accepted as ever.

Do not mark the kernel text read only if KPROBES is in the kernel; kprobes needs to hot-patch the kernel text to insert it's instrumentation. In this case, only mark the .rodata segment as read only.

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.

Nicolas Ferre reports oops from flush_dcache_page() on ARM when using SLUB: which reuses page->mapping as page->slab. The page_mapping() function, used by ARM and PA-RISC flush_dcache_page() implementations, must not confuse SLUB pages with those which have page->mapping set.

Add special-case handling for "handle_interruption" so that we can rewind past the interruption.

We need to keep a spare entry in the SRQ so that there always is a next WQE available when posting receives (so that we can tell the difference between a full queue and an empty queue). So subtract 1 from the value HW gives us before reporting the limit on SRQ entries to consumers. Found by Mellanox QA.

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: Michael S. Tsirkin <mst@dev.mellanox.co.il> Signed-off-by: Roland 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>.

If PORTS_IMPL register is zero, ahci initialize it to full mask corresponding to nr_ports in the CAP register. hpriv->cap, which is initialized at the end of the function, is incorrectly used as value of CAP causing ahci to always override PORTS_IMPL to 0x1 if it's zero.

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).
