Not only is that a supremely timing-critical path, but it's hopefully some day going to be lockless for the common case, and ima can't do that. Plus the integrity code doesn't even care about non-regular files, so it was always a total waste of time and effort.

In ext2_rename(), dir_page is acquired through ext2_dotdot(). It is then released through ext2_set_link() but only if old_dir != new_dir. Failing that, the pkmap reference count is never decremented and the page remains pinned forever. Repeat that a couple times with highmem pages and all pkmap slots get exhausted, and every further kmap() calls end up stalling on the pkmap_map_wait queue at which point the whole system comes to a halt.

The whole write-room thing is something that is up to the _caller_ to worry about, not the pty layer itself. The total buffer space will still be limited by the buffering routines themselves, so there is no advantage or need in having pty_write() artificially limit the size somehow. And what happened was that the caller (the n_tty line discipline, in this case) may have verified that there is room for 2 bytes to be written (for NL -> CRNL expansion), and it used to then do those writes as two single-byte writes. And if the first byte written (CR) then caused a new tty buffer to be allocated, pty_space() may have returned zero when trying to write the second byte (LF), and then incorrectly failed the write - leading to a lost newline character.

When translating CR to CRNL in the n_tty line discipline, we did it as two tty_put_char() calls. Which works, but is stupid, and has caused problems before too with bad interactions with the write_room() logic. The generic USB serial driver had that problem, for example. Now the pty layer had similar issues after being moved to the generic tty buffering code (in commit d945cb9c: "pty: Rework the pty layer to use the normal buffering logic"). So stop doing the silly separate two writes, and do it as a single write instead. That's what the n_tty layer already does for the space expansion of tabs (XTABS), and it means that we'll now always have just a single write for the CRNL to match the single 'tty_write_room()' test, which hopefully means that the next time somebody screws up buffering, it won't cause weeks of debugging.

Tom Horsley reports that his debugger hangs when it tries to read /proc/pid_of_tracee/maps, this happens since "mm_for_maps: take ->cred_guard_mutex to fix the race with exec" 04b836cbf19e885f8366bccb2e4b0474346c02d commit in 2.6.31. But the root of the problem lies in the fact that do_execve() path calls tracehook_report_exec() which can stop if the tracer sets PT_TRACE_EXEC. The tracee must not sleep in TASK_TRACED holding this mutex. Even if we remove ->cred_guard_mutex from mm_for_maps() and proc_pid_attr_write(), another task doing PTRACE_ATTACH should not hang until it is killed or the tracee resumes. With this patch do_execve() does not use ->cred_guard_mutex directly and we do not hold it throughout, instead: - introduce prepare_bprm_creds() helper, it locks the mutex and calls prepare_exec_creds() to initialize bprm->cred. - install_exec_creds() drops the mutex after commit_creds(), and thus before tracehook_report_exec()->ptrace_stop(). or, if exec fails, free_bprm() drops this mutex when bprm->cred != NULL which indicates install_exec_creds() was not called.

On low-memory systems, anti-fragmentation gets disabled as fragmentation cannot be avoided on a sufficiently large boundary to be worthwhile. Once disabled, there is a period of time when all the pageblocks are marked MOVABLE and the expectation is that they get marked UNMOVABLE at each call to __rmqueue_fallback(). However, when MAX_ORDER is large the pageblocks do not change ownership because the normal criteria are not met. This has the effect of prematurely breaking up too many large contiguous blocks. This is most serious on NOMMU systems which depend on high-order allocations to boot. This patch causes pageblocks to change ownership on every fallback when anti-fragmentation is disabled. This prevents the large blocks being prematurely broken up. This is a fix to commit 49255c61 [page allocator: move check for disabled anti-fragmentation out of fastpath] and the problem affects 2.6.31-rc8.

Fix the error handling in do_mmap_pgoff(). If do_mmap_shared_file() or do_mmap_private() fail, we jump to the error_put_region label at which point we cann __put_nommu_region() on the region - but we haven't yet added the region to the tree, and so __put_nommu_region() may BUG because the region tree is empty or it may corrupt the region tree. To get around this, we can afford to add the region to the region tree before calling do_mmap_shared_file() or do_mmap_private() as we keep nommu_region_sem write-locked, so no-one can race with us by seeing a transient region.

cancel_delayed_work() has to use del_timer_sync() to guarantee the timer function is not running after return. But most users doesn't actually need this, and del_timer_sync() has problems: it is not useable from interrupt, and it depends on every lock which could be taken from irq. Introduce __cancel_delayed_work() which calls del_timer() instead. The immediate reason for this patch is http://bugzilla.kernel.org/show_bug.cgi?id=13757 but hopefully this helper makes sense anyway. As for 13757 bug, actually we need requeue_delayed_work(), but its semantics are not yet clear. Merge this patch early to resolves cross-tree interdependencies between input and infiniband.

An Agere FW643 OHCI 1.1 card works fine for video reception from one camera but fails early if receiving from two cameras. After a short while, no IR IRQ events occur and the context control register does not react anymore. This happens regardless whether both IR DMA contexts are dual-buffer or one is dual-buffer and the other packet-per-buffer. This can be worked around by disabling dual buffer DMA mode entirely. http://sourceforge.net/mailarchive/message.php?msg_name=4A7C0594.2020208%40gmail.com (Reported by Samuel Audet.) In another report (by Jonathan Cameron), an FW643 works OK with two cameras in dual buffer mode. Whether this is due to different chip revisions or different usage patterns (different video formats) is not yet clear. However, as far as the current capabilities of firewire-core's isochronous I/O interface are concerned, simply switching off dual-buffer on non-working and working FW643s alike is not a problem in practice. We only need to revisit this issue if we are going to enhance the interface, e.g. so that applications can explicitly choose modes.
