2011-03-14Revert "oom: oom_kill_process: fix the child_points logic"Linus Torvalds
This reverts the parent commit. I hate doing that, but it's generating some discussion ("half of it is right"), and since I am planning on doing the 2.6.38 release later today we can punt it to stable if required. Let's not rock the boat right now. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2011-03-14oom: oom_kill_process: fix the child_points logicOleg Nesterov
oom_kill_process() starts with victim_points == 0. This means that (most likely) any child has more points and can be killed erroneously. Also, "children has a different mm" doesn't match the reality, we should check child->mm != t->mm. This check is not exactly correct if t->mm == NULL but this doesn't really matter, oom_kill_task() will kill them anyway. Note: "Kill all processes sharing p->mm" in oom_kill_task() is wrong too.

2011-03-14Fix corrupted OSF partition table parsingTimo Warns
The kernel automatically evaluates partition tables of storage devices. The code for evaluating OSF partitions contains a bug that leaks data from kernel heap memory to userspace for certain corrupted OSF partitions. In more detail: for (i = 0 ; i < le16_to_cpu(label->d_npartitions); i++, partition++) { iterates from 0 to d_npartitions - 1, where d_npartitions is read from the partition table without validation and partition is a pointer to an array of at most 8 d_partitions. Add the proper and obvious validation.

2011-03-14watchdog: hpwdt: eliminate section mismatch warningAxel Lin
hpwdt_init_nmi_decoding() is called in hpwdt_init_one error handling, thus remove the __devexit annotation of hpwdt_exit_nmi_decoding(). This patch fixes below warning: WARNING: drivers/watchdog/hpwdt.o(.devinit.text+0x36f): Section mismatch in reference from the function hpwdt_init_one() to the function .devexit.text:hpwdt_exit_nmi_decoding() The function __devinit hpwdt_init_one() references a function __devexit hpwdt_exit_nmi_decoding(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __devexit annotation of hpwdt_exit_nmi_decoding() so it may be used outside an exit section.

2011-03-14drm/radeon: fix problem with changing active VRAM size. (v2)Dave Airlie
So we used to use lpfn directly to restrict VRAM when we couldn't access the unmappable area, however this was removed in 93225b0d7bc030f4a93165347a65893685822d70 as it also restricted the gtt placements. However it was only later noticed that this broke on some hw. This removes the active_vram_size, and just explicitly sets it when it changes, TTM/drm_mm will always use the real_vram_size, and the active vram size will change the TTM size used for lpfn setting. We should re-work the fpfn/lpfn to per-placement at some point I suspect, but that is too late for this kernel. Hopefully this addresses: https://bugs.freedesktop.org/show_bug.cgi?id=35254 v2: fix reported useful VRAM size to userspace to be correct. Signed-off-by: Dave Airlie <airlied@redhat.com>

2011-03-13thp: fix page_referenced to modify mapcount/vm_flags only if page is foundAndrea Arcangeli
When vmscan.c calls page_referenced(), if an anon page was created before a process forked, rmap will search for it in both of the processes, even though one of them might have since broken COW. If the child process mlocks the vma where the COWed page belongs to, page_referenced() running on the page mapped by the parent would lead to *vm_flags getting VM_LOCKED set erroneously (leading to the references on the parent page being ignored and evicting the parent page too early). *mapcount would also be decremented by page_referenced_one even if the page wasn't found by page_check_address. This also lets pmdp_clear_flush_young_notify() go ahead on a pmd_trans_splitting() pmd. We hold the page_table_lock so __split_huge_page_map() must wait the pmdp_clear_flush_young_notify() to complete before it can modify the pmd. The pmd is also still mapped in userland so the young bit may materialize through a tlb miss before split_huge_page_map runs. This will provide a more accurate page_referenced() behavior during split_huge_page().

2011-03-12Btrfs: break out of shrink_delalloc earlierChris Mason
Josef had changed shrink_delalloc to exit after three shrink attempts, which wasn't quite enough because new writers could race in and steal free space. But it also fixed deadlocks and stalls as we tried to recover delalloc reservations. The code was tweaked to loop 1024 times, and would reset the counter any time a small amount of progress was made. This was too drastic, and with a lot of writers we can end up stuck in shrink_delalloc forever. The shrink_delalloc loop is fairly complex because the caller is looping too, and the caller will go ahead and force a transaction commit to make sure we reclaim space. This reworks things to exit shrink_delalloc when we've forced some writeback and the delalloc reservations have gone down. This means the writeback has not just started but has also finished at least some of the metadata changes required to reclaim delalloc space. If we've got this wrong, we're returning ENOSPC too early, which is a big improvement over the current behavior of hanging the machine. Test 224 in xfstests hammers on this nicely, and with 1000 writers trying to fill a 1GB drive we get our first ENOSPC at 93% full. The other writers are able to continue until we get 100%. This is a worst case test for btrfs because the 1000 writers are doing small IO, and the small FS size means we don't have a lot of room for metadata chunks.

2011-03-11NFS: NFSROOT should default to "proto=udp"Chuck Lever
There have been a number of recent reports that NFSROOT is no longer working with default mount options, but fails only with certain NICs. Brian Downing <bdowning@lavos.net> bisected to commit 56463e50 "NFS: Use super.c for NFSROOT mount option parsing". Among other things, this commit changes the default mount options for NFSROOT to use TCP instead of UDP as the underlying transport. TCP seems less able to deal with NICs that are slow to initialize. The system logs that have accompanied reports of problems all show that NFSROOT attempts to establish a TCP connection before the NIC is fully initialized, and thus the TCP connection attempt fails. When a TCP connection attempt fails during a mount operation, the NFS stack needs to fail the operation. Usually user space knows how and when to retry it. The network layer does not report a distinct error code for this particular failure mode. Thus, there isn't a clean way for the RPC client to see that it needs to retry in this case, but not in others. Because NFSROOT is used in some environments where it is not possible to update the kernel command line to specify "udp", the proper thing to do is change NFSROOT to use UDP by default, as it did before commit 56463e50. To make it easier to see how to change default mount options for NFSROOT and to distinguish default settings from mandatory settings, I've adjusted a couple of areas to document the specifics. root_nfs_cat() is also modified to deal with commas properly when concatenating strings containing mount option lists. This keeps root_nfs_cat() call sites simpler, now that we may be concatenating multiple mount option strings.

2011-03-11block: fix mis-synchronisation in blkdev_issue_zeroout()Lukas Czerner
BZ29402 https://bugzilla.kernel.org/show_bug.cgi?id=29402 We can hit serious mis-synchronization in bio completion path of blkdev_issue_zeroout() leading to a panic. The problem is that when we are going to wait_for_completion() in blkdev_issue_zeroout() we check if the bb.done equals issued (number of submitted bios). If it does, we can skip the wait_for_completition() and just out of the function since there is nothing to wait for. However, there is a ordering problem because bio_batch_end_io() is calling atomic_inc(&bb->done) before complete(), hence it might seem to blkdev_issue_zeroout() that all bios has been completed and exit. At this point when bio_batch_end_io() is going to call complete(bb->wait), bb and wait does not longer exist since it was allocated on stack in blkdev_issue_zeroout() ==> panic! (thread 1) (thread 2) bio_batch_end_io() blkdev_issue_zeroout() if(bb) { ... if (bb->end_io) ... bb->end_io(bio, err); ... atomic_inc(&bb->done); ... ... while (issued != atomic_read(&bb.done)) ... (let issued == bb.done) ... (do the rest of the function) ... return ret; complete(bb->wait); ^^^^^^^^ panic We can fix this easily by simplifying bio_batch and completion counting. Also remove bio_end_io_t *end_io since it is not used.

David did a back-merge in order to get commit 8909c9ad8ff0 ("net: don't allow CAP_NET_ADMIN to load non-netdev kernel modules") so that we can add Stephen Hemminger's fix to handle ip6 tunnels as well, which uses the MODULE_ALIAS_NETDEV() macro created by that change.

2011-03-10net: bridge builtin vs. ipv6 modularRandy Dunlap
When configs BRIDGE=y and IPV6=m, this build error occurs: br_multicast.c:(.text+0xa3341): undefined reference to `ipv6_dev_get_saddr' BRIDGE_IGMP_SNOOPING is boolean; if it were tristate, then adding depends on IPV6 || IPV6=n to BRIDGE_IGMP_SNOOPING would be a good fix. As it is currently, making BRIDGE depend on the IPV6 config works. Reported-by: Patrick Schaaf <netdev@bof.de> Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: David S.
