It doesn't happen always, overall rate is about 1/20. But, like other bugs, once when this happens, it continues to happen.

| 7ed47b7 | Nick Bowler | 20 October 2011, 12:16:55 UTC | crypto: ghash - Avoid null pointer dereference if no key is set The ghash_update function passes a pointer to gf128mul_4k_lle which will be NULL if ghash_setkey is not called or if the most recent call to ghash_setkey failed to allocate memory. This causes an oops. Fix this up by returning an error code in the null case. This is trivially triggered from unprivileged userspace through the AF_ALG interface by simply writing to the socket without setting a key. The ghash_final function has a similar issue, but triggering it requires a memory allocation failure in ghash_setkey _after_ at least one successful call to ghash_update.

| 486cf46 | Hugh Dickins | 19 October 2011, 19:50:35 UTC | mm: fix race between mremap and removing migration entry I don't usually pay much attention to the stale "? " addresses in stack backtraces, but this lucky report from Pawel Sikora hints that mremap's move_ptes() has inadequate locking against page migration. 3.0 BUG_ON(!PageLocked(p)) in migration_entry_to_page(): kernel BUG at include/linux/swapops.h:105! RIP: 0010:[<ffffffff81127b76>] [<ffffffff81127b76>] migration_entry_wait+0x156/0x160 [<ffffffff811016a1>] handle_pte_fault+0xae1/0xaf0 [<ffffffff810feee2>] ? __pte_alloc+0x42/0x120 [<ffffffff8112c26b>] ? do_huge_pmd_anonymous_page+0xab/0x310 [<ffffffff81102a31>] handle_mm_fault+0x181/0x310 [<ffffffff81106097>] ? vma_adjust+0x537/0x570 [<ffffffff81424bed>] do_page_fault+0x11d/0x4e0 [<ffffffff81109a05>] ? do_mremap+0x2d5/0x570 [<ffffffff81421d5f>] page_fault+0x1f/0x30 mremap's down_write of mmap_sem, together with i_mmap_mutex or lock, and pagetable locks, were good enough before page migration (with its requirement that every migration entry be found) came in, and enough while migration always held mmap_sem; but not enough nowadays, when there's memory hotremove and compaction. The danger is that move_ptes() lets a migration entry dodge around behind remove_migration_pte()'s back, so it's in the old location when looking at the new, then in the new location when looking at the old. Either mremap's move_ptes() must additionally take anon_vma lock(), or migration's remove_migration_pte() must stop peeking for is_swap_entry() before it takes pagetable lock. Consensus chooses the latter: we prefer to add overhead to migration than to mremapping, which gets used by JVMs and by exec stack setup.

Due to commit 92fc43b4159b518f5baae57301f26d770b0834c9 ("r8169: modify the flow of the hw reset."), rtl8169_hw_reset stomps during driver shutdown on RxConfig bits which are needed for WOL on some versions of the hardware. As these bits were formerly set from the r81{0x, 68}_pll_power_down methods, factor them out for use in the driver shutdown (rtl_shutdown) handler. I favored __rtl8169_get_wol() -hardware state indication- over RTL_FEATURE_WOL as the latter has become a good candidate for removal.

So, a panic occurs when both functions work in parallel. Why this happen: After null pointer check of bond->recv_probe, an sk_buff is duplicated and bond->recv_probe is called in bond_handle_frame. So, a panic occurs when bond_close() is called between the check and call of bond->recv_probe. Patch: This patch uses a local function pointer of bond->recv_probe in bond_handle_frame().

See one problem report below: * http://bugzilla.redhat.com/show_bug.cgi?id=741703 In order to keep things simple at this point in time, this patch fixes the problem by cloning the parent socket's LSM attributes to the newly created child socket.

| f36c23b | Gerrit Renker | 17 October 2011, 23:07:30 UTC | udplite: fast-path computation of checksum coverage Commit 903ab86d195cca295379699299c5fc10beba31c7 of 1 March this year ("udp: Add lockless transmit path") introduced a new fast TX path that broke the checksum coverage computation of UDP-lite, which so far depended on up->len (only set if the socket is locked and 0 in the fast path). Fixed by providing both fast- and slow-path computation of checksum coverage. The latter can be removed when UDP(-lite)v6 also uses a lockless transmit path.

| a84a79e | Linus Torvalds | 17 October 2011, 15:24:24 UTC | Avoid using variable-length arrays in kernel/sys.c The size is always valid, but variable-length arrays generate worse code for no good reason (unless the function happens to be inlined and the compiler sees the length for the simple constant it is). Also, there seems to be some code generation problem on POWER, where Henrik Bakken reports that register r28 can get corrupted under some subtle circumstances (interrupt happening at the wrong time?). That all indicates some seriously broken compiler issues, but since variable length arrays are bad regardless, there's little point in trying to chase it down. "Just don't do that, then".

This caused "sensors" and possibly other monitoring tools to report these sensors as "transistor" instead of "thermal diode". Furthermore, diode subtype selection (CPU vs. external) is only supported by the original W83627EHF/EHG. All later models only support CPU diode type, and some (NCT6776F) don't even have the register in question so we should avoid reading from it.

Revert back to use a kthread per filesystem which fixes all the above issues at the cost of having a task struct and stack around for each mounted filesystem. In addition this also gives us much better ways to diagnose any issues involving hung AIL pushing and removes a small amount of code.
