09c3e01 Input: do not use property bits when generating module alias The commit 8724ecb07229 ("Input: allow matching device IDs on property bits") started using property bits when generating module aliases for input handlers, but did not adjust the generation of MODALIAS attribute on input device uevents, breaking automatic module loading. Given that no handler currently uses property bits in their module tables, let's revert this part of the commit for now.

8d5f4b0 stmmac: Don't access tx_q->dirty_tx before netif_tx_lock This is the possible reason for different hard to reproduce problems on my ARMv7-SMP test system. The symptoms are in recent kernels imprecise external aborts, and in older kernels various kinds of network stalls and unexpected page allocation failures. My testing indicates that the trouble started between v4.5 and v4.6 and prevails up to v4.14. Using the dirty_tx before acquiring the spin lock is clearly wrong and was first introduced with v4.6.

864e2a1 ipv6: flowlabel: do not leave opt->tot_len with garbage When syzkaller team brought us a C repro for the crash [1] that had been reported many times in the past, I finally could find the root cause. If FlowLabel info is merged by fl6_merge_options(), we leave part of the opt_space storage provided by udp/raw/l2tp with random value in opt_space.tot_len, unless a control message was provided at sendmsg() time. Then ip6_setup_cork() would use this random value to perform a kzalloc() call. Undefined behavior and crashes. Fix is to properly set tot_len in fl6_merge_options() At the same time, we can also avoid consuming memory and cpu cycles to clear it, if every option is copied via a kmemdup(). This is the change in ip6_setup_cork().

66bdede of_mdio: Fix broken PHY IRQ in case of probe deferral If an Ethernet PHY is initialized before the interrupt controller it is connected to, a message like the following is printed: irq: no irq domain found for /interrupt-controller@e61c0000 ! However, the actual error is ignored, leading to a non-functional (POLL) PHY interrupt later: Micrel KSZ8041RNLI ee700000.ethernet-ffffffff:01: attached PHY driver [Micrel KSZ8041RNLI] (mii_bus:phy_addr=ee700000.ethernet-ffffffff:01, irq=POLL) Depending on whether the PHY driver will fall back to polling, Ethernet may or may not work. To fix this: 1. Switch of_mdiobus_register_phy() from irq_of_parse_and_map() to of_irq_get(). Unlike the former, the latter returns -EPROBE_DEFER if the interrupt controller is not yet available, so this condition can be detected. Other errors are handled the same as before, i.e. use the passed mdio->irq[addr] as interrupt. 2. Propagate and handle errors from of_mdiobus_register_phy() and of_mdiobus_register_device().

0247880 Merge branch 'mlxsw-fixes' Jiri Pirko says: ==================== mlxsw: spectrum: Configure TTL of "inherit" for offloaded tunnels Petr says: Currently mlxsw only offloads tunnels that are configured with TTL of "inherit" (which is the default). However, Spectrum defaults to 255 and the driver neglects to change the configuration. Thus the tunnel packets from offloaded tunnels always have TTL of 255, even though tunnels with explicit TTL of 255 are never actually offloaded. To fix this, introduce support for TIGCR, the register that keeps the related bits of global tunnel configuration, and use it on first offload to properly configure inheritance of TTL of tunnel packets from overlay packets. ==================== Signed-off-by: David S.

The existing implementation assumedthat the socket lock protected both of these paths when it actually only protects the SO_ATTACH_REUSEPORT path. Syzkaller triggered this double allocation by running these paths concurrently. This patch moves the check for double allocation into the reuseport_alloc function which is protected by a global spin lock.

54d4311 sock: correct sk_wmem_queued accounting on efault in tcp zerocopy Syzkaller hits WARN_ON(sk->sk_wmem_queued) in sk_stream_kill_queues after triggering an EFAULT in __zerocopy_sg_from_iter. On this error, skb_zerocopy_stream_iter resets the skb to its state before the operation with __pskb_trim. It cannot kfree_skb like datagram callers, as the skb may have data from a previous send call. __pskb_trim calls skb_condense for unowned skbs, which adjusts their truesize. These tcp skbuffs are owned and their truesize must add up to sk_wmem_queued. But they match because their skb->sk is NULL until tcp_transmit_skb. Temporarily set skb->sk when calling __pskb_trim to signal that the skbuffs are owned and avoid the skb_condense path.

They are targeted for net tree, note that once net gets merged into net-next, there will be a minor merge conflict due to signature change of the function find_good_pkt_pointers() as well as data_meta patterns present in net-next tree. You can just add bool false to the data_meta patterns and I will follow-up with properly converting the patterns for data_meta in a similar way. ==================== Signed-off-by: David S.

0fd4759 bpf: fix pattern matches for direct packet access Alexander had a test program with direct packet access, where the access test was in the form of data + X > data_end. In an unrelated change to the program LLVM decided to swap the branches and emitted code for the test in form of data + X <= data_end. We hadn't seen these being generated previously, thus verifier would reject the program. Therefore, fix up the verifier to detect all test cases, so we don't run into such issues in the future.

fb2a311 bpf: fix off by one for range markings with L{T, E} patterns During review I noticed that the current logic for direct packet access marking in check_cond_jmp_op() has an off by one for the upper right range border when marking in find_good_pkt_pointers() with BPF_JLT and BPF_JLE. It's not really harmful given access up to pkt_end is always safe, but we should nevertheless correct the range marking before it becomes ABI. If pkt_data' denotes a pkt_data derived pointer (pkt_data + X), then for pkt_data' < pkt_end in the true branch as well as for pkt_end <= pkt_data' in the false branch we mark the range with X although it should really be X - 1 in these cases. For example, X could be pkt_end - pkt_data, then when testing for pkt_data' < pkt_end the verifier simulation cannot deduce that a byte load of pkt_data' - 1 would succeed in this branch.

1f7c70d cpu/hotplug: Reset node state after operation The recent rework of the cpu hotplug internals changed the usage of the per cpu state->node field, but missed to clean it up after usage. So subsequent hotplug operations use the stale pointer from a previous operation and hand it into the callback functions. The callbacks then dereference a pointer which either belongs to a different facility or points to freed and potentially reused memory. In either case data corruption and crashes are the obvious consequence. Reset the node and the last pointers in the per cpu state to NULL after the operation which set them has completed.

52b4c86 net/ncsi: Enforce failover on link monitor timeout The NCSI channel has been configured to provide service if its link monitor timer is enabled, regardless of its state (inactive or active). So the timeout event on the link monitor indicates the out-of-service on that channel, for which a failover is needed. This sets NCSI_DEV_RESHUFFLE flag to enforce failover on link monitor timeout, regardless the channel's original state (inactive or active). Also, the link is put into "down" state to give the failing channel lowest priority when selecting for the active channel. The state of failing channel should be set to active in order for deinitialization and failover to be done.

e95c6cf Merge branch 'sockmap-fixes' John Fastabend says: ==================== sockmap fixes for net The following implements a set of fixes for sockmap and changes the API slightly in a few places to reduce preempt_disable/enable scope. We do this here in net because it requires an API change and this avoids getting stuck with legacy API going forward. The short description: Access to skb mark is removed, it is problematic when we add features in the future because mark is a union and used by the TCP/socket code internally. We don't want to expose this to the BPF programs or let programs change the values. The other change is caching metadata in the skb itself between when the BPF program returns a redirect code and the core code implements the redirect. This avoids having per cpu metadata. Finally, tighten restriction on using sockmap to CAP_NET_ADMIN and only SOCK_STREAM sockets. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> 20 October 2017, 12:01:30 UTC

f7e9cb1 bpf: remove mark access for SK_SKB program types The skb->mark field is a union with reserved_tailroom which is used in the TCP code paths from stream memory allocation. Allowing SK_SKB programs to set this field creates a conflict with future code optimizations, such as "gifting" the skb to the egress path instead of creating a new skb and doing a memcpy. Because we do not have a released version of SK_SKB yet lets just remove it for now. A more appropriate scratch pad to use at the socket layer is dev_scratch, but lets add that in future kernels when needed.

34f7950 bpf: avoid preempt enable/disable in sockmap using tcp_skb_cb region SK_SKB BPF programs are run from the socket/tcp context but early in the stack before much of the TCP metadata is needed in tcp_skb_cb. So we can use some unused fields to place BPF metadata needed for SK_SKB programs when implementing the redirect function. This allows us to drop the preempt disable logic. It does however require an API change so sk_redirect_map() has been updated to additionally provide ctx_ptr to skb. Note, we do however continue to disable/enable preemption around actual BPF program running to account for map updates.

1cc276c sctp: add the missing sock_owned_by_user check in sctp_icmp_redirect Now sctp processes icmp redirect packet in sctp_icmp_redirect where it calls sctp_transport_dst_check in which tp->dst can be released. The problem is before calling sctp_transport_dst_check, it doesn't check sock_owned_by_user, which means tp->dst could be freed while a process is accessing it with owning the socket. An use-after-free issue could be triggered by this. This patch is to fix it by checking sock_owned_by_user before calling sctp_transport_dst_check in sctp_icmp_redirect, so that it would not release tp->dst if users still hold sock lock. Besides, the same issue fixed in commit 45caeaa5ac0b ("dccp/tcp: fix routing redirect race") on sctp also needs this check.

eb39a7c clockevents/drivers/cs5535: Improve resilience to spurious interrupts The interrupt handler mfgpt_tick() is not robust versus spurious interrupts which happen before the clock event device is registered and fully initialized. The reason is that the safe guard against spurious interrupts solely checks for the clockevents shutdown state, but lacks a check for detached state. If the interrupt hits while the device is in detached state it passes the safe guard and dereferences the event handler call back which is NULL. Add the missing state check.

ce56a86 x86/mm: Limit mmap() of /dev/mem to valid physical addresses Currently, it is possible to mmap() any offset from /dev/mem. If a program mmaps() /dev/mem offsets outside of the addressable limits of a system, the page table can be corrupted by setting reserved bits. For example if you mmap() offset 0x0001000000000000 of /dev/mem on an x86_64 system with a 48-bit bus, the page fault handler will be called with error_code set to RSVD.

a961e40 membarrier: Provide register expedited private command This introduces a "register private expedited" membarrier command which allows eventual removal of important memory barrier constraints on the scheduler fast-paths. It changes how the "private expedited" membarrier command (new to 4.14) is used from user-space. This new command allows processes to register their intent to use the private expedited command. This affects how the expedited private command introduced in 4.14-rc is meant to be used, and should be merged before 4.14 final. Processes are now required to register before using MEMBARRIER_CMD_PRIVATE_EXPEDITED, otherwise that command returns EPERM. This fixes a problem that arose when designing requested extensions to sys_membarrier() to allow JITs to efficiently flush old code from instruction caches. Several potential algorithms are much less painful if the user register intent to use this functionality early on, for example, before the process spawns the second thread. Registering at this time removes the need to interrupt each and every thread in that process at the first expedited sys_membarrier() system call.

9b5db7a Input: goodix - poll the 'buffer status' bit before reading data The Goodix panel triggers an interrupt on touch events. However, its registers will contain the valid values a short time after the interrupt, and not when it's raised. At that moment, the 'buffer status' bit is set. Previously, if the 'buffer status' bit was not set when the registers were read, the data was discarded and no input event was emitted, causing "finger down" or "finger up" events to be missed sometimes. This went unnoticed until v4.9, as the DesignWare I2C driver commonly used with this driver had enough latency for that bug to never trigger until commit 2702ea7dbec5 ("i2c: designware: wait for disable/enable only if necessary"). Now, in the IRQ handler we will poll (with a timeout) the 'buffer status' bit and process the data of the panel as soon as this bit gets set. Note that the Goodix panel will send a few spurious interrupts after the 'finger up' event, in which the 'buffer status' bit will never be set.

8f75bc3 Input: tca8418 - enable interrupt after it has been requested Currently, enabling keypad interrupts is one of the first operations done on the keypad, even before the interrupt is requested, so there is a small time window where the keypad can fire interrupts but the driver is not yet ready to handle them. It's fine for level interrupts because they will be handled anyway, but not so much for edge ones. This commit modifies and moves the function in charge of configuring the keypad. Enabling interrupts is now the last thing done on the keypad, and after the interrupt has been requested by the driver. Writing to the config register was also used to determine if the device was indeed present on the bus or not, this has been replaced by reading the lock/event count register to keep the same functionality.

72ecd79 ARM: ux500: Fix regression while init PM domains The commit afece3ab9a36 ("PM / Domains: Add time accounting to various genpd states") causes a boot regression for ux500. The problem occurs when the ux500 machine code calls pm_genpd_init(), which since the above change triggers a call to ktime_get(). More precisely, because ux500 initializes PM domains in the init_IRQ() phase of the boot, timekeeping has not yet been initialized. Fix the problem by moving the initialization of the PM domains to after timekeeping has been initialized. Fixes: afece3ab9a36 ("PM / Domains: Add time accounting to various genpd..")
