The race is as follows: Suppose a multi-threaded task forks a new process (on cpu A), thus bumping up the ref count on all the pages. While the fork is occurring (and thus we have marked all the PTEs as read-only), another thread in the original process (on cpu B) tries to write to a huge page, taking an access violation from the write-protect and calling hugetlb_cow(). Now, suppose the fork() fails. It will undo the COW and decrement the ref count on the pages, so the ref count on the huge page drops back to 1. Meanwhile hugetlb_cow() also decrements the ref count by one on the original page, since the original address space doesn't need it any more, having copied a new page to replace the original page. This leaves the ref count at zero, and when we call unlock_page(), we panic. fork on CPU A fault on CPU B ============= ============== ... down_write(&parent->mmap_sem); down_write_nested(&child->mmap_sem); ... while duplicating vmas if error break; ... up_write(&child->mmap_sem); up_write(&parent->mmap_sem); ... down_read(&parent->mmap_sem); ... lock_page(page); handle COW page_mapcount(old_page) == 2 alloc and prepare new_page ... handle error page_remove_rmap(page); put_page(page); ... fold new_page into pte page_remove_rmap(page); put_page(page); ... oops ==> unlock_page(page); up_read(&parent->mmap_sem); The solution is to take an extra reference to the page while we are holding the lock on it.

RTC stores time and date in several registers. Due to the fact that these registers can't be read instantaneously, there is a chance that reading from counting registers gives an error of one minute, one hour, one day, etc. To address this issue, the RTC has hardware support to copy the RTC counting registers to static shadowed registers. The current implementation does not use this feature, and in a stress test, we can reproduce this error at a rate of around two times per 300000 readings. Fix the implementation to ensure that the right snapshot of time is captured. Signed-off-by:

/proc/sys/kernel/random/boot_id can be read concurrently by userspace processes. If two (or more) user-space processes concurrently read boot_id when sysctl_bootid is not yet assigned, a race can occur making boot_id differ between the reads. Because the whole point of the boot id is to be unique across a kernel execution, fix this by protecting this operation with a spinlock. Given that this operation is not frequently used, hitting the spinlock on each call should not be an issue. Signed-off-by:

This merges the 32- and 64-bit versions of the x86 strncpy_from_user() by just rewriting it in C rather than the ancient inline asm versions that used lodsb/stosb and had been duplicated for (trivial) differences between the 32-bit and 64-bit versions. While doing that, it also speeds them up by doing the accesses a word at a time. Finally, the new routines also properly handle the case of hitting the end of the address space, which we have never done correctly before (fs/namei.c has a hack around it for that reason). Despite all these improvements, it actually removes more lines than it adds, due to the de-duplication. Also, we no longer export (or define) the legacy __strncpy_from_user() function (that was defined to not do the user permission checks), since it's not actually used anywhere, and the user address space checks are built in to the new code. Other architecture maintainers have been notified that the old hack in fs/namei.c will be going away in the 3.5 merge window, in case they copied the x86 approach of being a bit cavalier about the end of the address space.

This patch allows caching of the rindex glock. We were previously setting the GL_NOCACHE bit when the glock was released. That forced the rindex inode to be invalidated, which caused us to re-read rindex at the next access. However, it caused the glock to be unnecessarily bounced around the cluster. This patch allows the glock to remain cached, but it still causes the rindex to be re-read once it has been written to by gfs2_grow. Ben and I have tested single-node gfs2_grow cases and I've tested clustered gfs2_grow cases on my four-node cluster. Signed-off-by:

commit a546498f introduced a regression on 32-bit when irq tracing is enabled by exposing an old bug in our irq tracing code for exception entry. The code would save and restore some GPRs around the calls to the C lockdep code, however, it tries to be too smart for its own good and restores some of the GPRs from the exception frame (as saved there on exception entry). However, for page faults, we do replace those GPRs with arguments to do_page_fault before we call transfer_to_handler and so restoring from the exception frame is plain wrong in this case. This was fine as long as we didn't touch the interrupt state when taking page fault, but when I started doing it, it would trigger the lockdep calls and the bug. This fixes it by cleaning up that code a bit. It did create a small stack frame for the sake of backtraces, so let's make it a bit bigger and use it to save and restore the stuff we care about.

Commit f02e8a65 ("module: Sort exported symbols") sorts symbols placing each of them in its own elf section. This sorting and merging into the canonical sections are done by the linker. Unfortunately modpost to generate Module.symvers file parses vmlinux.o (which is not linked yet) and all modules object files (which aren't linked yet). These aren't sanitized by the linker yet. That breaks modpost that can't detect license properly for modules. This patch makes modpost aware of the new exported symbols structure. [ This above is a slightly corrected version of the explanation of the problem, copied from commit 62a26356 ("modpost: Fix modpost's license checking V3").

The task handoff notifier leaks task_struct since it never gets freed after the callback returns NOTIFY_OK, which means it is responsible for doing so. It turns out the lowmemorykiller actually doesn't need this notifier at all. It's used to prevent unnecessary killing by waiting for a thread to exit as a result of lowmem_shrink(), however, it's possible to do this in the same way the kernel oom killer works by setting TIF_MEMDIE and avoid killing if we're still waiting for it to exit. The kernel oom killer will already automatically set TIF_MEMDIE for threads that are attempting to allocate memory that have a fatal signal. The thread selected by lowmem_shrink() will have such a signal after the lowmemorykiller sends it a SIGKILL, so this won't result in an unnecessary use of memory reserves for the thread to exit. This has the added benefit that we don't have to rely on CONFIG_PROFILING to prevent needlessly killing tasks. Reported-by:
