commit 4ece9009 upstream. sit0 device allocates its percpu storage twice : - One time in ipip6_tunnel_init() - One time in ipip6_fb_tunnel_init() Thus we leak 48 bytes per possible cpu per network namespace dismantle. ipip6_fb_tunnel_init() can be much simpler and does not return an error, and should be called after register_netdev() Note that ipip6_tunnel_clone_6rd() also needs to be called after register_netdev() (calling ipip6_tunnel_init()) Fixes: ebe084aa ("sit: Use ipip6_tunnel_init as the ndo_init function.")

commit 70910791 upstream. The lt4112 is a HP branded Huawei me906e modem. Like other Huawei modems, it does not have a fixed interface to function mapping. Instead it uses a Huawei specific scheme: functions are mapped by subclass and protocol. However, the HP vendor ID is used for modems from many different manufacturers using different schemes, so we cannot apply a generic vendor rule like we do for the Huawei vendor ID. Replace the previous lt4112 entry pointing to an arbitrary interface number with a device specific subclass + protocol match. Reported-and-tested-by:

commit 8ce675ff upstream. Either of pskb_pull() or pskb_trim() may fail under low memory conditions. If rds_tcp_data_recv() ignores such failures, the application will receive corrupted data because the skb has not been correctly carved to the RDS datagram size. Avoid this by handling pskb_pull/pskb_trim failure in the same manner as the skb_clone failure: bail out of rds_tcp_data_recv(), and retry via the deferred call to rds_send_worker() that gets set up on ENOMEM from rds_tcp_read_sock() Signed-off-by:

commit 899f0c1c upstream. The internal clock of the master chip, which is usually 125MHz, is only half (62.5MHz) for the slave chips. So we have to adjust the uartclk for all the slave ports.

commit 96a5d18b upstream. The Exar XR17V358 chip usually provides only 8 ports. But two chips can be combined to act as a single 16 port chip. Therefor one chip is configured as master the second as slave by connecting the mode pin to VCC (master) or GND (slave). Then the master chip is reporting a different device-id depending on whether a slave is detected or not. The UARTs 8-15 are addressed from 0x2000-0x3fff. So the offset of 0x400 from UART to UART can be used to address all 16 ports as before. See: https://www.exar.com/common/content/document.ashx?id=1587 page 11 Signed-off-by:

commit c02b0501 upstream. When doing memcpy/memset of EQEs, we should use sizeof struct mlx4_eqe as the base size and not caps.eqe_size which could be bigger. If caps.eqe_size is bigger than the struct mlx4_eqe then we corrupt data in the master context. When using a 64 byte stride, the memcpy copied over 63 bytes to the slave_eq structure. This resulted in copying over the entire eqe of interest, including its ownership bit -- and also 31 bytes of garbage into the next WQE in the slave EQ -- which did NOT include the ownership bit (and therefore had no impact). However, once the stride is increased to 128, we are overwriting the ownership bits of *three* eqes in the slave_eq struct. This results in an incorrect ownership bit for those eqes, which causes the eq to seem to be full. The issue therefore surfaced only once 128-byte EQEs started being used in SRIOV and (overarchitectures that have 128/256 byte cache-lines such as PPC) - e.g after commit 77507aa2 "net/mlx4_core: Enable CQE/EQE stride support".

commit 1acea4f6 upstream. We can't rely on PPPOX_ZOMBIE to decide whether to clear po->pppoe_dev. PPPOX_ZOMBIE can be set by pppoe_disc_rcv() even when po->pppoe_dev is NULL. So we have no guarantee that (sk->sk_state & PPPOX_ZOMBIE) implies (po->pppoe_dev != NULL). Since we're releasing a PPPoE socket, we want to release the pppoe_dev if it exists and reset sk_state to PPPOX_DEAD, no matter the previous value of sk_state. So we can just check for po->pppoe_dev and avoid any assumption on sk->sk_state. Fixes: 2b018d57 ("pppoe: drop PPPOX_ZOMBIEs in pppoe_release") Signed-off-by:

commit 93efac3f upstream. The IPv6 IPsec pre-encap path performs fragmentation for tunnel-mode packets. That is, we perform fragmentation pre-encap rather than post-encap. A check was added later to ensure that proper MTU information is passed back for locally generated traffic. Unfortunately this check was performed on all IPsec packets, including transport-mode packets. What's more, the check failed to take GSO into account. The end result is that transport-mode GSO packets get dropped at the check. This patch fixes it by moving the tunnel mode check forward as well as adding the GSO check.

commit d01552a7 upstream. This reverts commit 7eb41885. This commit is poorly justified, I can find not discusison in email, and it clearly causes a problem. If a device which is being recovered fails and is subsequently re-added to an array, there could easily have been changes to the array *before* the point where the recovery was up to. So the recovery must start again from the beginning. If a spare is being recovered and fails, then when it is re-added we really should do a bitmap-based recovery up to the recovery-offset, and then a full recovery from there. Before this reversion, we only did the "full recovery from there" which is not corect. After this reversion with will do a full recovery from the start, which is safer but not ideal. It will be left to a future patch to arrange the two different styles of recovery. Reported-and-tested-by:

commit b8a9d66d upstream. After commit 566c09c5 ("raid5: relieve lock contention in get_active_stripe()") __find_stripe() is called under conf->hash_locks + hash. But handle_stripe_clean_event() calls remove_hash() under conf->device_lock. Under some cirscumstances the hash chain can be circuited, and we get an infinite loop with disabled interrupts and locked hash lock in __find_stripe(). This leads to hard lockup on multiple CPUs and following system crash. I was able to reproduce this behavior on raid6 over 6 ssd disks.

commit bae818ee upstream. rbd requires stable pages, as it performs a crc of the page data before they are send to the OSDs. But since kernel 3.9 (patch 1d1d1a76 "mm: only enforce stable page writes if the backing device requires it") it is not assumed anymore that block devices require stable pages. This patch sets the necessary flag to get stable pages back for rbd. In a ceph installation that provides multiple ext4 formatted rbd devices "bad crc" messages appeared regularly (ca 1 message every 1-2 minutes on every OSD that provided the data for the rbd) in the OSD-logs before this patch. After this patch this messages are pretty much gone (only ca 1-2 / month / OSD). Signed-off-by:

commit 9702970c upstream. This reverts commit e306dfd0. With this patch applied, we were the only architecture making this sort of adjustment to the PC calculation in the unwinder. This causes problems for ftrace, where the PC values are matched against the contents of the stack frames in the callchain and fail to match any records after the address adjustment. Whilst there has been some effort to change ftrace to workaround this, those patches are not yet ready for mainline and, since we're the odd architecture in this regard, let's just step in line with other architectures (like arch/arm/) for now.

commit 3fc89adb upstream. Currently a number of Crypto API operations may fail when a signal occurs. This causes nasty problems as the caller of those operations are often not in a good position to restart the operation. In fact there is currently no need for those operations to be interrupted by user signals at all. All we need is for them to be killable. This patch replaces the relevant calls of signal_pending with fatal_signal_pending, and wait_for_completion_interruptible with wait_for_completion_killable, respectively. Signed-off-by:

This function has a comment claiming it doesn't need to disable preemption around the module lookup because it holds a reference to the module it wants to find, which therefore cannot go away. This is wrong (and a false optimization too, preempt_disable() is really rather cheap, and I doubt any of this is on uber critical paths, otherwise it would've retained a pointer to the actual module anyway and avoided the second lookup). While its true that the module cannot go away while we hold a reference on it, the data structure we do the lookup in very much _CAN_ change while we do the lookup. Therefore fix the comment and add the required preempt_disable(). Reported-by:

Fixing that by making sure it's erased only once before freeing cm_id_priv. Fixes: a977049d ('[PATCH] IB: Add the kernel CM implementation') Signed-off-by:
