patch ace2e92e in mainline. XFS leaves stray mappings around when it vmaps memory to make it virtually contigious. This upsets Xen if one of those pages is being recycled into a pagetable, since it finds an extra writable mapping of the page. This patch solves the problem in a brute force way, by making XFS always eagerly unmap its mappings. [ Stable: This works around a bug in 2.6.23. We may come up with a better solution for mainline, but this seems like a low-impact fix for the stable kernel. ] Signed-off-by:

patch e3d26976 in mainline. The kernel's copy of struct vcpu_register_vcpu_info was out of date, at best causing the hypercall to fail and the guest kernel to fall back to the old mechanism, or worse, causing random memory corruption. Signed-off-by:

patch 9f79991d in mainline. When a pagetable is no longer in use, it must be unpinned so that its pages can be freed. However, this is only possible if there are no stray uses of the pagetable. The code currently deals with all the usual cases, but there's a rare case where a vcpu is changing cr3, but is doing so lazily, and the change hasn't actually happened by the time the pagetable is unpinned, even though it appears to have been completed. This change adds a second per-cpu cr3 variable - xen_current_cr3 - which tracks the actual state of the vcpu cr3. It is only updated once the actual hypercall to set cr3 has been completed. Other processors wishing to unpin a pagetable can check other vcpu's xen_current_cr3 values to see if any cross-cpu IPIs are needed to clean things up. Signed-off-by:

commit a24864a1 uml: definitively kill subprocesses on panic In a stock 2.6.22.6 kernel, poweroff a user mode linux guest (2.6.22.6 running in skas0 mode) will halt the host linux. I think the reason is the kernel thread abort because of a bug. Then the sys_reboot in process of user mode linux guest is not trapped by the user mode linux kernel and is executed by host. I think it is better to make sure all of our children process to quit when user mode linux kernel abort. [ jdike - the kernel process needs to ignore SIGTERM, plus the waitpid/kill loop is needed to make sure that all of our children are dead before the kernel exits ] Signed-off-by:

commit 189872f9 in mainline. uml: don't use glibc asm/user.h Stop including asm/user.h from libc - it seems to be disappearing from distros. It's replaced with sys/user.h which defines user_fpregs_struct and user_fpxregs_struct instead of user_i387_struct and struct user_fxsr_struct on i386. As a bonus, on x86_64, I get to dump some stupid typedefs which were needed in order to get asm/user.h to compile. Signed-off-by:

patch a76ab5c1 in mainline. When GDB writes a breakpoint into address area of inferior process the kernel needs to invalidate the modified memory in the inferior which is done by calling flush_cache_page which in turns calls r4k_flush_cache_page and local_r4k_flush_cache_page for VSMP or SMTC kernel via r4k_on_each_cpu(). As the VSMP and SMTC SMP kernels for 34K are running on a single shared caches it is possible to get away without interprocessor function calls. This optimization is implemented in r4k_on_each_cpu, so local_r4k_flush_cache_page is only ever called on the local CPU. This is where the following code in local_r4k_flush_cache_page() strikes: /* * If ownes no valid ASID yet, cannot possibly have gotten * this page into the cache. */ if (cpu_context(smp_processor_id(), mm) == 0) return; On VSMP and SMTC had a function of cpu_context() for each CPU(TC). So in case another CPU than the CPU executing local_r4k_cache_flush_page has not accessed the mm but one of the other CPUs has there may be data to be flushed in the cache yet local_r4k_cache_flush_page will falsely return leaving the I-cache inconsistent for the breakpoint. While the issue was discovered with GDB it also exists in local_r4k_flush_cache_range() and local_r4k_flush_cache(). Fixed by introducing a new function has_valid_asid which on MT kernels returns true if a mm is active on any processor in the system. This is relativly expensive since for memory acccesses in that loop cache misses have to be assumed but it seems the most viable solution for 2.6.23 and older -stable kernels. Signed-off-by:

patch 6eca9004 in mainline. For the locking to work, only the tag map and tag bit map may be shared (incidentally, I was just explaining this to Nick yesterday, but I apparently didn't review the code well enough myself). But we also share the busy list! The busy_list must be queue private, or we need a block_queue_tag covering lock as well. So we have to move the busy_list to the queue. This'll work fine, and it'll actually also fix a problem with blk_queue_invalidate_tags() which will invalidate tags across all shared queues. This is a bit confusing, the low level driver should call it for each queue seperately since otherwise you cannot kill tags on just a single queue for eg a hard drive that stops responding. Since the function has no callers currently, it's not an issue. This is fixed with commit 6eca9004 in Linus' tree. Signed-off-by:

patch 487e9bf2 in mainline. It's possible to provoke unionfs (not yet in mainline, though in mm and some distros) to hit shmem_writepage's BUG_ON(page_mapped(page)). I expect it's possible to provoke the 2.6.23 ecryptfs in the same way (but the 2.6.24 ecryptfs no longer calls lower level's ->writepage). This came to light with the recent find that AOP_WRITEPAGE_ACTIVATE could leak from tmpfs via write_cache_pages and unionfs to userspace. There's already a fix (e4230030 - writeback: don't propagate AOP_WRITEPAGE_ACTIVATE) in the tree for that, and it's okay so far as it goes; but insufficient because it doesn't address the underlying issue, that shmem_writepage expects to be called only by vmscan (relying on backing_dev_info capabilities to prevent the normal writeback path from ever approaching it). That's an increasingly fragile assumption, and ramdisk_writepage (the other source of AOP_WRITEPAGE_ACTIVATEs) is already careful to check wbc->for_reclaim before returning it. Make the same check in shmem_writepage, thereby sidestepping the page_mapped BUG also. Signed-off-by:

[FUTEX]: Fix address computation in compat code. [ Upstream commit: 3c5fd9c7 ] compat_exit_robust_list() computes a pointer to the futex entry in userspace as follows: (void __user *)entry + futex_offset 'entry' is a 'struct robust_list __user *', and 'futex_offset' is a 'compat_long_t' (typically a 's32'). Things explode if the 32-bit sign bit is set in futex_offset. Type promotion sign extends futex_offset to a 64-bit value before adding it to 'entry'. This triggered a problem on sparc64 running 32-bit applications which would lock up a cpu looping forever in the fault handling for the userspace load in handle_futex_death(). Compat userspace runs with address masking (wherein the cpu zeros out the top 32-bits of every effective address given to a memory operation instruction) so the sparc64 fault handler accounts for this by zero'ing out the top 32-bits of the fault address too. Since the kernel properly uses the compat_uptr interfaces, kernel side accesses to compat userspace work too since they will only use addresses with the top 32-bit clear. Because of this compat futex layer bug we get into the following loop when executing the get_user() load near the top of handle_futex_death(): 1) load from address '0xfffffffff7f16bd8', FAULT 2) fault handler clears upper 32-bits, processes fault for address '0xf7f16bd8' which succeeds 3) goto #1 I want to thank Bernd Zeimetz, Josip Rodin, and Fabio Massimo Di Nitto for their tireless efforts helping me track down this bug.

patch 05aa3450 in mainline. SLUB: Fix memory leak by not reusing cpu_slab Fix the memory leak that may occur when we attempt to reuse a cpu_slab that was allocated while we reenabled interrupts in order to be able to grow a slab cache. The per cpu freelist may contain objects and in that situation we may overwrite the per cpu freelist pointer loosing objects. This only occurs if we find that the concurrently allocated slab fits our allocation needs. If we simply always deactivate the slab then the freelist will be properly reintegrated and the memory leak will go away. Signed-off-by:

The kernel has for random historical reasons allowed ptrace() accesses to access (and insert) pages into the page cache above the size of the file. However, Nick broke that by mistake when doing the new fault handling in commit 54cb8821 ("mm: merge populate and nopage into fault (fixes nonlinear)". The breakage caused a hang with gdb when trying to access the invalid page. The ptrace "feature" really isn't worth resurrecting, since it really is wrong both from a portability _and_ from an internal page cache validity standpoint. So this removes those old broken remnants, and fixes the ptrace() hang in the process. Noticed and bisected by Duane Griffin, who also supplied a test-case (quoth Nick: "Well that's probably the best bug report I've ever had, thanks Duane!").

patch 97855b49 in mainline. It's currently possible to send posix_locks_deadlock() into an infinite loop (under the BKL). For now, fix this just by bailing out after a few iterations. We may want to fix this in a way that better clarifies the semantics of deadlock detection. But that will take more time, and this minimal fix is probably adequate for any realistic scenario, and is simple enough to be appropriate for applying to stable kernels now.
