由 Josef Bacik 提交于
A user reported that he was getting immediate disconnects with my sndtimeo patch applied. This is because by default the OSS nbd client doesn't set a timeout, so we end up setting the sndtimeo to 0, which of course means we have send errors a lot. Instead only set our sndtimeo if the user specified a timeout, otherwise we'll just wait forever like we did previously.

Commit 3d476263 ("tcp: remove poll() flakes when receiving RST") in v4.12 changed the order in which ->sk_state_change() and ->sk_error_report() are called when a socket is shut down - sk_state_change() is now called first. This causes xs_tcp_state_change() -> xs_sock_mark_closed() -> xprt_disconnect_done() to wake all pending tasked with -EAGAIN. When the ->sk_error_report() callback arrives, it is too late to pass the error on, and it is lost. As easy way to demonstrate the problem caused is to try to start rpc.nfsd while rcpbind isn't running. nfsd will attempt a tcp connection to rpcbind. A ECONNREFUSED error is returned, but sunrpc code loses the error and keeps retrying. If it saw the ECONNREFUSED, it would abort. To fix this, handle the sk->sk_err in the TCP_CLOSE branch of xs_tcp_state_change().

We have 2 functions using the same sched_task callback: - PEBS drain for free running counters - LBR save/store Both of them are called from intel_pmu_sched_task() and either of them can be unwillingly triggered when the other one is configured to run. Let's say there's PEBS drain configured in sched_task callback for the event, but in the callback itself (intel_pmu_sched_task()) we will also run the code for LBR save/restore, which we did not ask for, but the code in intel_pmu_sched_task() does not check for that. This can lead to extra cycles in some perf monitoring, like when we monitor PEBS event without LBR data. # perf record --no-timestamp -c 10000 -e cycles:p ./perf bench sched pipe -l 1000000 (We need PEBS, non freq/non timestamp event to enable the sched_task callback) The perf stat of cycles and msr:write_msr for above command before the change: ... Performance counter stats for './perf record --no-timestamp -c 10000 -e cycles:p \ ./perf bench sched pipe -l 1000000' (5 runs): 18,519,557,441 cycles:k 91,195,527 msr:write_msr 29.334476406 seconds time elapsed And after the change: ... Performance counter stats for './perf record --no-timestamp -c 10000 -e cycles:p \ ./perf bench sched pipe -l 1000000' (5 runs): 18,704,973,540 cycles:k 27,184,720 msr:write_msr 16.977875900 seconds time elapsed There's no affect on cycles:k because the sched_task happens with events switched off, however the msr:write_msr tracepoint counter together with almost 50% of time speedup show the improvement. Monitoring LBR event and having extra PEBS drain processing in sched_task callback showed just a little speedup, because the drain function does not do much extra work in case there is no PEBS data. Adding conditions to recognize the configured work that needs to be done in the x86_pmu's sched_task callback.

We're missing ctx lock when iterating children siblings within the perf_read path for group reading. Following race and crash can happen: User space doing read syscall on event group leader: T1: perf_read lock event->ctx->mutex perf_read_group lock leader->child_mutex __perf_read_group_add(child) list_for_each_entry(sub, &leader->sibling_list, group_entry) ----> sub might be invalid at this point, because it could get removed via perf_event_exit_task_context in T2 Child exiting and cleaning up its events: T2: perf_event_exit_task_context lock ctx->mutex list_for_each_entry_safe(child_event, next, &child_ctx->event_list,... perf_event_exit_event(child) lock ctx->lock perf_group_detach(child) unlock ctx->lock ----> child is removed from sibling_list without any sync with T1 path above ... free_event(child) Before the child is removed from the leader's child_list, (and thus is omitted from perf_read_group processing), we need to ensure that perf_read_group touches child's siblings under its ctx->lock.

From Alexander Potapenko. 9) TCP BBR congestion control fixes from Neal Cardwell. 10) Fix SKB fragment handling in bcmgenet driver, from Doug Berger. 11) BPF_CGROUP_RUN_PROG_SOCK_OPS needs to check for null __sk, from Cong Wang. 12) xmit_recursion in ppp driver needs to be per-device not per-cpu, from Gao Feng. 13) Cannot release skb->dst in UDP if IP options processing needs it. From Paolo Abeni. 14) Some netdev ioctl ifr_name[] NULL termination fixes. From Alexander Levin and myself. 15) Revert some rtnetlink notification changes that are causing regressions, from David Ahern. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (83 commits) net: bonding: Fix transmit load balancing in balance-alb mode rds: Make sure updates to cp_send_gen can be observed net: ethernet: ti: cpsw: Push the request_irq function to the end of probe ipv4: initialize fib_trie prior to register_netdev_notifier call. rtnetlink: allocate more memory for dev_set_mac_address() net: dsa: b53: Add missing ARL entries for BCM53125 bpf: more tests for mixed signed and unsigned bounds checks bpf: add test for mixed signed and unsigned bounds checks bpf: fix up test cases with mixed signed/unsigned bounds bpf: allow to specify log level and reduce it for test_verifier bpf: fix mixed signed/unsigned derived min/max value bounds ipv6: avoid overflow of offset in ip6_find_1stfragopt net: tehuti: don't process data if it has not been copied from userspace Revert "rtnetlink: Do not generate notifications for CHANGEADDR event" net: dsa: mv88e6xxx: Enable CMODE config support for 6390X dt-binding: ptp: Add SoC compatibility strings for dte ptp clock NET: dwmac: Make dwmac reset unconditional net: Zero terminate ifr_name in dev_ifname(). wireless: wext: terminate ifr name coming from userspace netfilter: fix netfilter_net_init() return ...

balance-alb mode used to have transmit dynamic load balancing feature enabled by default. However, transmit dynamic load balancing no longer works in balance-alb after commit 8b426dc5 ("bonding: remove hardcoded value"). Both balance-tlb and balance-alb use the function bond_do_alb_xmit() to send packets. This function uses the parameter tlb_dynamic_lb. tlb_dynamic_lb used to have the default value of 1 for balance-alb, but now the value is set to 0 except in balance-tlb. Re-enable transmit dyanmic load balancing by initializing tlb_dynamic_lb for balance-alb similar to balance-tlb.

cp->cp_send_gen is treated as a normal variable, although it may be used by different threads. This is fixed by using {READ,WRITE}_ONCE when it is incremented and READ_ONCE when it is read outside the {acquire,release}_in_xmit protection. Normative reference from the Linux-Kernel Memory Model: Loads from and stores to shared (but non-atomic) variables should be protected with the READ_ONCE(), WRITE_ONCE(), and ACCESS_ONCE(). Clause 5.1.2.4/25 in the C standard is also relevant.

Push the request_irq function to the end of probe so as to ensure all the required fields are populated in the event of an ISR getting executed right after requesting the irq. Currently while loading the crash kernel a crash was seen as soon as devm_request_threaded_irq was called. This was due to n->poll being NULL which is called as part of net_rx_action function.

Net stack initialization currently initializes fib-trie after the first call to netdevice_notifier() call. In fact fib_trie initialization needs to happen before first rtnl_register(). It does not cause any problem since there are no devices UP at this moment, but trying to bring 'lo' UP at initialization would make this assumption wrong and exposes the issue.

virtnet_set_mac_address() interprets mac address as struct sockaddr, but upper layer only allocates dev->addr_len which is ETH_ALEN + sizeof(sa_family_t) in this case. We lack a unified definition for mac address, so just fix the upper layer, this also allows drivers to interpret it to struct sockaddr freely.
