2011-10-24x86: Fix S4 regressionTakashi Iwai1-2/+1
Commit 4b239f458 ("x86-64, mm: Put early page table high") causes a S4 regression since 2.6.39, namely the machine reboots occasionally at S4 resume. It doesn't happen always, overall rate is about 1/20. But, like other bugs, once when this happens, it continues to happen. This patch fixes the problem by essentially reverting the memory assignment in the older way. Signed-off-by: Takashi Iwai <[email protected]> Cc: <[email protected]> Cc: Rafael J.

Fix memory leak introduced by commit a6e50b409d3f9e0833e69c3c9cca822e8fa4adbb (dm snapshot: skip reading origin when overwriting complete chunk). When allocating a set of jobs from kc->job_pool, job->master_job must be set (to point to itself) so that the mempool item gets freed when the master_job completes. master_job was introduced by commit c6ea41fbbe08f270a8edef99dc369faf809d1bd6 (dm kcopyd: preallocate sub jobs to avoid deadlock) Reported-by: Michael Leun <[email protected]> Cc: Mikulas Patocka <[email protected]> Signed-off-by: Alasdair G Kergon <[email protected]>

2011-10-21crypto: ghash - Avoid null pointer dereference if no key is setNick Bowler1-0/+6
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.

2011-10-19mm: fix race between mremap and removing migration entryHugh Dickins1-4/+4
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.

FB scratch indices are dword indices, but we were treating them as byte indices. As such, we were getting the wrong FB scratch data for non-0 indices. Fix the indices and guard the indexing against indices larger than the scratch allocation. Fixes memory corruption on some boards if data was written past the end of the FB scratch array.

2011-10-19pptp: pptp_rcv_core() misses pskb_may_pull() callEric Dumazet1-8/+12
e1000e uses paged frags, so any layer incorrectly pulling bytes from skb can trigger a BUG in skb_pull() [951.142737] [<ffffffff813d2f36>] skb_pull+0x15/0x17 [951.142737] [<ffffffffa0286824>] pptp_rcv_core+0x126/0x19a [pptp] [951.152725] [<ffffffff813d17c4>] sk_receive_skb+0x69/0x105 [951.163558] [<ffffffffa0286993>] pptp_rcv+0xc8/0xdc [pptp] [951.165092] [<ffffffffa02800a3>] gre_rcv+0x62/0x75 [gre] [951.165092] [<ffffffff81410784>] ip_local_deliver_finish+0x150/0x1c1 [951.177599] [<ffffffff81410634>] ? ip_local_deliver_finish+0x0/0x1c1 [951.177599] [<ffffffff81410846>] NF_HOOK.clone.7+0x51/0x58 [951.177599] [<ffffffff81410996>] ip_local_deliver+0x51/0x55 [951.177599] [<ffffffff814105b9>] ip_rcv_finish+0x31a/0x33e [951.177599] [<ffffffff8141029f>] ? ip_rcv_finish+0x0/0x33e [951.204898] [<ffffffff81410846>] NF_HOOK.clone.7+0x51/0x58 [951.214651] [<ffffffff81410bb5>] ip_rcv+0x21b/0x246 pptp_rcv_core() is a nice example of a function assuming everything it needs is available in skb head.
