commit f7134eea upstream. A temperature conversion can take 750 ms and when possible the w1_therm slave driver drops the bus_mutex to allow other bus operations, but that includes operations such as a periodic slave search, which can remove this slave when it is no longer detected. If that happens the sl->family_data will be freed and set to NULL causing w1_slave_show to crash when it wakes up. Signed-off-by:

commit 535fb906 upstream. Avoid that srp_terminate_io() can get invoked while srp_queuecommand() is in progress. This patch avoids that an I/O timeout can trigger the following kernel warning: WARNING: at drivers/infiniband/ulp/srp/ib_srp.c:1447 srp_terminate_io+0xef/0x100 [ib_srp]() Call Trace: [<ffffffff814c65a2>] dump_stack+0x4e/0x68 [<ffffffff81051f71>] warn_slowpath_common+0x81/0xa0 [<ffffffff8105204a>] warn_slowpath_null+0x1a/0x20 [<ffffffffa075f51f>] srp_terminate_io+0xef/0x100 [ib_srp] [<ffffffffa07495da>] __rport_fail_io_fast+0xba/0xc0 [scsi_transport_srp] [<ffffffffa0749a90>] rport_fast_io_fail_timedout+0xe0/0xf0 [scsi_transport_srp] [<ffffffff8106e09b>] process_one_work+0x1db/0x780 [<ffffffff8106e75b>] worker_thread+0x11b/0x450 [<ffffffff81073c64>] kthread+0xe4/0x100 [<ffffffff814cf26c>] ret_from_fork+0x7c/0xb0 See also patch "scsi_transport_srp: Add transport layer error handling" (commit ID 29c17324).

commit be34c62d upstream. Introduce the helper function srp_wait_for_queuecommand(). Move the definition of scsi_request_fn_active(). Add a comment above srp_wait_for_queuecommand() that support for scsi-mq needs to be added. This patch does not change any functionality. A second call to srp_wait_for_queuecommand() will be introduced in the next patch. Signed-off-by:

commit 1b852bce upstream. Fresh mounts of proc and sysfs are a very special case that works very much like a bind mount. Unfortunately the current structure can not preserve the MNT_LOCK... mount flags. Therefore refactor the logic into a form that can be modified to preserve those lock bits. Add a new filesystem flag FS_USERNS_VISIBLE that requires some mount of the filesystem be fully visible in the current mount namespace, before the filesystem may be mounted. Move the logic for calling fs_fully_visible from proc and sysfs into fs/namespace.c where it has greater access to mount namespace state. Signed-off-by:

commit ebb6ad73 upstream. VMID Control 0 BIT[2:1] is VMID Divider Enable and Select 00 = VMID disabled (for OFF mode) 01 = 2 x 50kΩ divider (for normal operation) 10 = 2 x 250kΩ divider (for low power standby) 11 = 2 x 5kΩ divider (for fast start-up) So WM8903_VMID_RES_250K should be 2 << 1, which is 4.

commit 63781394 upstream. request_any_context_irq() returns a negative value on failure. It returns either IRQC_IS_HARDIRQ or IRQC_IS_NESTED on success. So fix testing return value of request_any_context_irq(). Also fixup the return value of devm_request_any_context_irq() to make it consistent with request_any_context_irq().

commit 084609bf upstream. Setting a dev_pm_ops suspend/resume pair of callbacks but not a set of hibernation callbacks means those pm functions will not be called upon hibernation - that leads to system crash on ARM during freezing if gpio-led is used in combination with CPU led trigger. It may happen after freeze_noirq stage (GPIO is suspended) and before syscore_suspend stage (CPU led trigger is suspended) - usually when disable_nonboot_cpus() is called.

commit 0dd23f94 upstream. Commit 007bea09 (intel_pstate: Add setting voltage value for baytrail P states.) introduced byt_set_pstate() with the assumption that it would always be run by the CPU whose MSR is to be written by it. It turns out, however, that is not always the case in practice, so modify byt_set_pstate() to enforce the MSR write done by it to always happen on the right CPU.

commit 29c4afc4 upstream. There is NULL pointer dereference possible during statistics update if the route used for OOTB responce is removed at unfortunate time. If the route exists when we receive OOTB packet and we finally jump into sctp_packet_transmit() to send ABORT, but in the meantime route is removed under our feet, we take "no_route" path and try to update stats with IP_INC_STATS(sock_net(asoc->base.sk), ...). But sctp_ootb_pkt_new() used to prepare responce packet doesn't call sctp_transport_set_owner() and therefore there is no asoc associated with this packet. Probably temporary asoc just for OOTB responces is overkill, so just introduce a check like in all other places in sctp_packet_transmit(), where "asoc" is dereferenced. To reproduce this, one needs to 0. ensure that sctp module is loaded (otherwise ABORT is not generated) 1. remove default route on the machine 2. while true; do ip route del [interface-specific route] ip route add [interface-specific route] done 3. send enough OOTB packets (i.e. HB REQs) from another host to trigger ABORT responce On x86_64 the crash looks like this: BUG: unable to handle kernel NULL pointer dereference at 0000000000000020 IP: [<ffffffffa05ec9ac>] sctp_packet_transmit+0x63c/0x730 [sctp] PGD 0 Oops: 0000 [#1] PREEMPT SMP Modules linked in: ...

commit eb686231 upstream. When limiting phy link speed using "max-speed" to 100mbps or less on a giga bit phy, phy never completes auto negotiation and phy state machine is held in PHY_AN. Fixing this issue by comparing the giga bit advertise though phydev->supported doesn't have it but phy has BMSR_ESTATEN set. So that auto negotiation is restarted as old and new advertise are different and link comes up fine. Signed-off-by:

commit dfea2aa6 upstream. tcp_fastopen_reset_cipher really cannot be called from interrupt context. It allocates the tcp_fastopen_context with GFP_KERNEL and calls crypto_alloc_cipher, which allocates all kind of stuff with GFP_KERNEL. Thus, we might sleep when the key-generation is triggered by an incoming TFO cookie-request which would then happen in interrupt- context, as shown by enabling CONFIG_DEBUG_ATOMIC_SLEEP: [ 36.001813] BUG: sleeping function called from invalid context at mm/slub.c:1266 [ 36.003624] in_atomic(): 1, irqs_disabled(): 0, pid: 1016, name: packetdrill [ 36.004859] CPU: 1 PID: 1016 Comm: packetdrill Not tainted 4.1.0-rc7 #14 [ 36.006085] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.7.5-0-ge51488c-20140602_164612-nilsson.home.kraxel.org 04/01/2014 [ 36.008250] 00000000000004f2 ffff88007f8838a8 ffffffff8171d53a ffff880075a084a8 [ 36.009630] ffff880075a08000 ffff88007f8838c8 ffffffff810967d3 ffff88007f883928 [ 36.011076] 0000000000000000 ffff88007f8838f8 ffffffff81096892 ffff88007f89be00 [ 36.012494] Call Trace: [ 36.012953] <IRQ> [<ffffffff8171d53a>] dump_stack+0x4f/0x6d [ 36.014085] [<ffffffff810967d3>] ___might_sleep+0x103/0x170 [ 36.015117] [<ffffffff81096892>] __might_sleep+0x52/0x90 [ 36.016117] [<ffffffff8118e887>] kmem_cache_alloc_trace+0x47/0x190 [ 36.017266] [<ffffffff81680d82>] ? tcp_fastopen_reset_cipher+0x42/0x130 [ 36.018485] [<ffffffff81680d82>] tcp_fastopen_reset_cipher+0x42/0x130 [ 36.019679] [<ffffffff81680f01>] tcp_fastopen_init_key_once+0x61/0x70 [ 36.020884] [<ffffffff81680f2c>] __tcp_fastopen_cookie_gen+0x1c/0x60 [ 36.022058] [<ffffffff816814ff>] tcp_try_fastopen+0x58f/0x730 [ 36.023118] [<ffffffff81671788>] tcp_conn_request+0x3e8/0x7b0 [ 36.024185] [<ffffffff810e3872>] ? __module_text_address+0x12/0x60 [ 36.025327] [<ffffffff8167b2e1>] tcp_v4_conn_request+0x51/0x60 [ 36.026410] [<ffffffff816727e0>] tcp_rcv_state_process+0x190/0xda0 [ 36.027556] [<ffffffff81661f97>] ? __inet_lookup_established+0x47/0x170 [ 36.028784] [<ffffffff8167c2ad>] tcp_v4_do_rcv+0x16d/0x3d0 [ 36.029832] [<ffffffff812e6806>] ? security_sock_rcv_skb+0x16/0x20 [ 36.030936] [<ffffffff8167cc8a>] tcp_v4_rcv+0x77a/0x7b0 [ 36.031875] [<ffffffff816af8c3>] ? iptable_filter_hook+0x33/0x70 [ 36.032953] [<ffffffff81657d22>] ip_local_deliver_finish+0x92/0x1f0 [ 36.034065] [<ffffffff81657f1a>] ip_local_deliver+0x9a/0xb0 [ 36.035069] [<ffffffff81657c90>] ? ip_rcv+0x3d0/0x3d0 [ 36.035963] [<ffffffff81657569>] ip_rcv_finish+0x119/0x330 [ 36.036950] [<ffffffff81657ba7>] ip_rcv+0x2e7/0x3d0 [ 36.037847] [<ffffffff81610652>] __netif_receive_skb_core+0x552/0x930 [ 36.038994] [<ffffffff81610a57>] __netif_receive_skb+0x27/0x70 [ 36.040033] [<ffffffff81610b72>] process_backlog+0xd2/0x1f0 [ 36.041025] [<ffffffff81611482>] net_rx_action+0x122/0x310 [ 36.042007] [<ffffffff81076743>] __do_softirq+0x103/0x2f0 [ 36.042978] [<ffffffff81723e3c>] do_softirq_own_stack+0x1c/0x30 This patch moves the call to tcp_fastopen_init_key_once to the places where a listener socket creates its TFO-state, which always happens in user-context (either from the setsockopt, or implicitly during the listen()-call) Cc: Eric Dumazet <eric.dumazet@gmail.com> Cc: Hannes Frederic Sowa <hannes@stressinduktion.org> Fixes: 222e83d2 ("tcp: switch tcp_fastopen key generation to net_get_random_once") Signed-off-by:

commit 2c51a97f upstream. The lockless lookups can return entry that is unlinked. Sometimes they get reference before last neigh_cleanup_and_release, sometimes they do not need reference. Later, any modification attempts may result in the following problems: 1. entry is not destroyed immediately because neigh_update can start the timer for dead entry, eg. on change to NUD_REACHABLE state. As result, entry lives for some time but is invisible and out of control. 2. __neigh_event_send can run in parallel with neigh_destroy while refcnt=0 but if timer is started and expired refcnt can reach 0 for second time leading to second neigh_destroy and possible crash. Thanks to Eric Dumazet and Ying Xue for their work and analyze on the __neigh_event_send change.

It returns the old value unconditionally, but f->num_members may have changed since the last store. Ensure that the return value is always < num.

commit 2dab80a8 upstream. After the ->set() spinlocks were removed br_stp_set_bridge_priority was left running without any protection when used via sysfs. It can race with port add/del and could result in use-after-free cases and corrupted lists. Tested by running port add/del in a loop with stp enabled while setting priority in a loop, crashes are easily reproducible. The spinlocks around sysfs ->set() were removed in commit: 14f98f25 ("bridge: range check STP parameters") There's also a race condition in the netlink priority support that is fixed by this change, but it was introduced recently and the fixes tag covers it, just in case it's needed the commit is: af615762 ("bridge: add ageing_time, stp_state, priority over netlink") Signed-off-by:

commit 2d45a02d upstream. ->auto_asconf_splist is per namespace and mangled by functions like sctp_setsockopt_auto_asconf() which doesn't guarantee any serialization. Also, the call to inet_sk_copy_descendant() was backuping ->auto_asconf_list through the copy but was not honoring ->do_auto_asconf, which could lead to list corruption if it was different between both sockets. This commit thus fixes the list handling by using ->addr_wq_lock spinlock to protect the list. A special handling is done upon socket creation and destruction for that. Error handlig on sctp_init_sock() will never return an error after having initialized asconf, so sctp_destroy_sock() can be called without addrq_wq_lock. The lock now will be take on sctp_close_sock(), before locking the socket, so we don't do it in inverse order compared to sctp_addr_wq_timeout_handler(). Instead of taking the lock on sctp_sock_migrate() for copying and restoring the list values, it's preferred to avoid rewritting it by implementing sctp_copy_descendant(). Issue was found with a test application that kept flipping sysctl default_auto_asconf on and off, but one could trigger it by issuing simultaneous setsockopt() calls on multiple sockets or by creating/destroying sockets fast enough. This is only triggerable locally. Fixes: 9f7d653b ("sctp: Add Auto-ASCONF support (core).") Reported-by:

commit fb05e7a8 upstream. We saw excessive direct memory compaction triggered by skb_page_frag_refill. This causes performance issues and add latency. Commit 5640f768 introduces the order-3 allocation. According to the changelog, the order-3 allocation isn't a must-have but to improve performance. But direct memory compaction has high overhead. The benefit of order-3 allocation can't compensate the overhead of direct memory compaction. This patch makes the order-3 page allocation atomic. If there is no memory pressure and memory isn't fragmented, the alloction will still success, so we don't sacrifice the order-3 benefit here. If the atomic allocation fails, direct memory compaction will not be triggered, skb_page_frag_refill will fallback to order-0 immediately, hence the direct memory compaction overhead is avoided. In the allocation failure case, kswapd is waken up and doing compaction, so chances are allocation could success next time. alloc_skb_with_frags is the same. The mellanox driver does similar thing, if this is accepted, we must fix the driver too.

commit 1a040eac upstream. Since the addition of sysfs multicast router support if one set multicast_router to "2" more than once, then the port would be added to the hlist every time and could end up linking to itself and thus causing an endless loop for rlist walkers. So to reproduce just do: echo 2 > multicast_router; echo 2 > multicast_router; in a bridge port and let some igmp traffic flow, for me it hangs up in br_multicast_flood(). Fix this by adding a check in br_multicast_add_router() if the port is already linked. The reason this didn't happen before the addition of multicast_router sysfs entries is because there's a !hlist_unhashed check that prevents it. Signed-off-by:

The test run took a while and hasn't finished after close to 2 hours. The crash happened right after I gave up and killed the test (after 107m) with Ctrl+C." The crash happened because a NULL inode pointer got passed into locks_get_lock_context. The call chain indicates that file_inode(filp) returned NULL, which means that f_inode was NULL. Since that's zeroed out in __fput, that suggests that this filp pointer outlived the last reference. Looking at the code, that seems possible. We copy the struct file_lock that's passed in, but if the task is signalled at an inopportune time we can end up trying to use that file_lock in rpciod context after the process that requested it has already returned (and possibly put its filp reference). Fix this by taking an extra reference to the filp when we allocate the lock info, and put it in nfs4_lock_release. Reported-by:

commit f104765b upstream. If hardware doesn't support DecodeAssist - a feature that provides more information about the intercept in the VMCB, KVM decodes the instruction and then updates the next_rip vmcb control field. However, NRIP support itself depends on cpuid Fn8000_000A_EDX[NRIPS]. Since skip_emulated_instruction() doesn't verify nrip support before accepting control.next_rip as valid, avoid writing this field if support isn't present. Signed-off-by:

commit 412c98c1 upstream. The hwrng output buffers (2) are cast inside of a a struct (caam_rng_ctx) allocated in one DMA-tagged region. While the kernel's heap allocator should place the overall struct on a cacheline aligned boundary, the 2 buffers contained within may not necessarily align. Consenquently, the ends of unaligned buffers may not fully flush, and if so, stale data will be left behind, resulting in small repeating patterns. This fix aligns the buffers inside the struct. Note that not all of the data inside caam_rng_ctx necessarily needs to be DMA-tagged, only the buffers themselves require this. However, a fix would incur the expense of error-handling bloat in the case of allocation failure. Signed-off-by:

commit 6fd4b156 upstream. Multiple function in asynchronous hashing use a saved-state block, a.k.a. struct caam_hash_state, which holds a stash of information between requests (init/update/final). Certain values in this state block are loaded for processing using an inline-if, and when this is done, the potential for uninitialized data can pose conflicts. Therefore, this patch improves initialization of state data to prevent false assignments using uninitialized data in the state block. This patch addresses the following traceback, originating in ahash_final_ctx(), although a problem like this could certainly exhibit other symptoms: kernel BUG at arch/arm/mm/dma-mapping.c:465!
