2019-11-22ipmi: fix ipmb_poll()'s return typeLuc Van Oostenryck
ipmb_poll() is defined as returning 'unsigned int' but the .poll method is declared as returning '__poll_t', a bitwise type. Fix this by using the proper return type and using the EPOLL constants instead of the POLL ones, as required for __poll_t.

This changes system reboot for socfpga to issue a cold reboot by default instead of a warm reboot. Warm reboot can still be used by setting reboot_mode to REBOOT_WARM (e.g. via kernel command line 'reboot='), but this patch ensures cold reboot is issued for both REBOOT_COLD and REBOOT_HARD.

2019-11-22ALSA: aloop: Remove redundant locking in timer open functionAndrew Gabbasov
loopback_parse_timer_id() uses snd_card_ref(), that can lock on mutex, also snd_timer_instance_new() uses non-atomic allocation, that can sleep. So, both functions can not be called from loopback_snd_timer_open() with cable->lock spinlock locked. Moreover, most part of loopback_snd_timer_open() function body works when the opposite stream of the same cable does not yet exist, and the current stream is not yet completely open and can't be running, so existing locking of loopback->cable_lock mutex is enough to protect from conflicts with simultaneous opening or closing. Locking of cable->lock spinlock is not needed in this case.

2019-11-22SUNRPC: Capture completion of all RPC tasksChuck Lever
RPC tasks on the backchannel never invoke xprt_complete_rqst(), so there is no way to report their tk_status at completion. Also, any RPC task that exits via rpc_exit_task() before it is replied to will also disappear without a trace. Introduce a trace point that is symmetrical with rpc_task_begin that captures the termination status of each RPC task. Sample trace output for callback requests initiated on the server: kworker/u8:12-448 [003] 127.025240: rpc_task_end: task:50@3 flags=ASYNC|DYNAMIC|SOFT|SOFTCONN|SENT runstate=RUNNING|ACTIVE status=0 action=rpc_exit_task kworker/u8:12-448 [002] 127.567310: rpc_task_end: task:51@3 flags=ASYNC|DYNAMIC|SOFT|SOFTCONN|SENT runstate=RUNNING|ACTIVE status=0 action=rpc_exit_task kworker/u8:12-448 [001] 130.506817: rpc_task_end: task:52@3 flags=ASYNC|DYNAMIC|SOFT|SOFTCONN|SENT runstate=RUNNING|ACTIVE status=0 action=rpc_exit_task Odd, though, that I never see trace_rpc_task_complete, either in the forward or backchannel.

2019-11-22seg6: allow local packet processing for SRv6 End.DT6 behaviorAndrea Mayer
End.DT6 behavior makes use of seg6_lookup_nexthop() function which drops all packets that are destined to be locally processed. However, DT* should be able to deliver decapsulated packets that are destined to local addresses. Function seg6_lookup_nexthop() is also used by DX6, so in order to maintain compatibility I created another routing helper function which is called seg6_lookup_any_nexthop(). This function is able to take into account both packets that have to be processed locally and the ones that are destined to be forwarded directly to another machine. Hence, seg6_lookup_any_nexthop() is used in DT6 rather than seg6_lookup_nexthop() to allow local delivery. Signed-off-by: Andrea Mayer <andrea.mayer@uniroma2.it> Signed-off-by: David S.

Pankaj Sharma fixes the fallout in the m_can_platform part, which appeared with the introduction of the m_can platform framework. ==================== Signed-off-by: David S.

The effect is intended to eventually be similar to BQL, but byte queue limits are not useful in wifi where the actual throughput can vary by around 4 orders of magnitude.

2019-11-22docs, parallelism: Rearrange how jobserver reservations are madeKees Cook
Rasmus correctly observed that the existing jobserver reservation only worked if no other build targets were specified. The correct approach is to hold the jobserver slots until sphinx has finished. To fix this, the following changes are made: - refactor (and rename) scripts/jobserver-exec to set an environment variable for the maximally reserved jobserver slots and exec a child, to release the slots on exit. - create Documentation/scripts/parallel-wrapper.sh which examines both $PARALLELISM and the detected "-jauto" logic from Documentation/Makefile to decide sphinx's final -j argument. - chain these together in Documentation/Makefile Suggested-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> Link: https://lore.kernel.org/lkml/eb25959a-9ec4-3530-2031-d9d716b40b20@rasmusvillemoes.dk Signed-off-by: Kees Cook <keescook@chromium.org> Link: https://lore.kernel.org/r/20191121205929.40371-4-keescook@chromium.org Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2019-11-22docs, parallelism: Do not leak blocking mode to other readersKees Cook
Setting non-blocking via a local copy of the jobserver file descriptor is safer than just assuming other reader processes with the same fd open are prepared for it to be non-blocking.

2019-11-22tipc: support in-order name publication eventsTuong Lien
It is observed that TIPC service binding order will not be kept in the publication event report to user if the service is subscribed after the bindings. For example, services are bound by application in the following order: Server: bound port A to {18888,66,66} scope 2 Server: bound port A to {18888,33,33} scope 2 Now, if a client subscribes to the service range (e.g. {18888, 0-100}), it will get the 'TIPC_PUBLISHED' events in that binding order only when the subscription is started before the bindings. Otherwise, if started after the bindings, the events will arrive in the opposite order: Client: received event for published {18888,33,33} Client: received event for published {18888,66,66} For the latter case, it is clear that the bindings have existed in the name table already, so when reported, the events' order will follow the order of the rbtree binding nodes (- a node with lesser 'lower'/'upper' range value will be first). This is correct as we provide the tracking on a specific service status (available or not), not the relationship between multiple services. However, some users expect to see the same order of arriving events irrespective of when the subscription is issued. This turns out to be easy to fix. We now add functionality to ensure that publication events always are issued in the same temporal order as the corresponding bindings were performed. v2: replace the unnecessary macro - 'publication_after()' with inline function. v3: reuse 'time_after32()' instead of reinventing the same exact code.

2019-11-22tipc: update replicast capability for broadcast send linkHoang Le
When setting up a cluster with non-replicast/replicast capability supported. This capability will be disabled for broadcast send link in order to be backwards compatible. However, when these non-support nodes left and be removed out the cluster. We don't update this capability on broadcast send link. Then, some of features that based on this capability will also disabling as unexpected. In this commit, we make sure the broadcast send link capabilities will be re-calculated as soon as a node removed/rejoined a cluster.

2019-11-22udp: drop skb extensions before marking skb statelessFlorian Westphal
Once udp stack has set the UDP_SKB_IS_STATELESS flag, later skb free assumes all skb head state has been dropped already. This will leak the extension memory in case the skb has extensions other than the ipsec secpath, e.g. bridge nf data. To fix this, set the UDP_SKB_IS_STATELESS flag only if we don't have extensions or if the extension space can be free'd.
