2015-05-18sched: always use blk_schedule_flush_plug in io_schedule_outShaohua Li
block plug callback could sleep, so we introduce a parameter 'from_schedule' and corresponding drivers can use it to destinguish a schedule plug flush or a plug finish. Unfortunately io_schedule_out still uses blk_flush_plug(). This causes below output (Note, I added a might_sleep() in raid1_unplug to make it trigger faster, but the whole thing doesn't matter if I add might_sleep). In raid1/10, this can cause deadlock. This patch makes io_schedule_out always uses blk_schedule_flush_plug. This should only impact drivers (as far as I know, raid 1/10) which are sensitive to the 'from_schedule' parameter.

2015-05-18vxlan: correct typo in call to unregister_netdevice_queueJohn W. Linville
By inspection, this appears to be a typo. The gating comparison involves vxlan->dev rather than dev. In fact, dev is the iterator in the preceding loop above but it is actually constant in the 2nd loop. Use of dev seems to be a bad cut-n-paste from the prior call to unregister_netdevice_queue.

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for net-next. Briefly speaking, cleanups and minor fixes for ipset from Jozsef Kadlecsik and Serget Popovich, more incremental updates to make br_netfilter a better place from Florian Westphal, ARP support to the x_tables mark match / target from and context Zhang Chunyu and the addition of context to know that the x_tables runs through nft_compat. More specifically, they are: 1) Fix sparse warning in ipset/ip_set_hash_ipmark.c when fetching the IPSET_ATTR_MARK netlink attribute, from Jozsef Kadlecsik. 2) Rename STREQ macro to STRNCMP in ipset, also from Jozsef. 3) Use skb->network_header to calculate the transport offset in ip_set_get_ip{4,6}_port(). From Alexander Drozdov. 4) Reduce memory consumption per element due to size miscalculation, this patch and follow up patches from Sergey Popovich. 5) Expand nomatch field from 1 bit to 8 bits to allow to simplify mtype_data_reset_flags(), also from Sergey. 6) Small clean for ipset macro trickery. 7) Fix error reporting when both ip_set_get_hostipaddr4() and ip_set_get_extensions() from per-set uadt functions. 8) Simplify IPSET_ATTR_PORT netlink attribute validation. 9) Introduce HOST_MASK instead of hardcoded 32 in ipset. 10) Return true/false instead of 0/1 in functions that return boolean in the ipset code. 11) Validate maximum length of the IPSET_ATTR_COMMENT netlink attribute. 12) Allow to dereference from ext_*() ipset macros. 13) Get rid of incorrect definitions of HKEY_DATALEN. 14) Include linux/netfilter/ipset/ip_set.h in the x_tables set match. 15) Reduce nf_bridge_info size in br_netfilter, from Florian Westphal. 16) Release nf_bridge_info after POSTROUTING since this is only needed from the physdev match, also from Florian. 17) Reduce size of ipset code by deinlining ip_set_put_extensions(), from Denys Vlasenko. 18) Oneliner to add ARP support to the x_tables mark match/target, from Zhang Chunyu. 19) Add context to know if the x_tables extension runs from nft_compat, to address minor problems with three existing extensions. 20) Correct return value in several seqfile *_show() functions in the netfilter tree, from Joe Perches. ==================== Signed-off-by: David S.

2015-05-18watchdog: Fix merge 'conflict'Peter Zijlstra
Two watchdog changes that came through different trees had a non conflicting conflict, that is, one changed the semantics of a variable but no actual code conflict happened. So the merge appeared fine, but the resulting code did not behave as expected. Commit 195daf665a62 ("watchdog: enable the new user interface of the watchdog mechanism") changes the semantics of watchdog_user_enabled, which thereafter is only used by the functions introduced by b3738d293233 ("watchdog: Add watchdog enable/disable all functions"). There further appears to be a distinct lack of serialization between setting and using watchdog_enabled, so perhaps we should wrap the {en,dis}able_all() things in watchdog_proc_mutex. This patch fixes a s2r failure reported by Michal; which I cannot readily explain. But this does make the code internally consistent again.

The Lenovo ThinkPad L450 requires the ALC292_FIXUP_TPT440_DOCK fix in order to get sound output on the docking stations audio port. This patch was tested using a ThinkPad L450 (20DSS00B00) using kernel 4.0.3 and a ThinkPad Pro Dock.

2015-05-17netlink: Use random autobind roverHerbert Xu
Currently we use a global rover to select a port ID that is unique. This used to work consistently when it was protected with a global lock. However as we're now lockless, the global rover can exhibit pathological behaviour should multiple threads all stomp on it at the same time. Granted this will eventually resolve itself but the process is suboptimal. This patch replaces the global rover with a pseudorandom starting point to avoid this issue.

2015-05-17net: dsa: bcm_sf2: properly propagate carrier down state for MoCAFlorian Fainelli
MoCA interfaces require the use of an user-space daemon (mocad) which will typically use cmd->autoneg to force the link. This is causing other network manager applications not to get proper carrier down notifications because of the following sequence of events: - link down interrupt is received, link is set to 0 by the interrupt handler - fixed_link update callback runs and updates the BMSR register accordingly - PHY library polls the PHY for link status, sees the link is down, proceeds with reporting that - mocad gets notified of the link state and call phy_ethtool_sset() with cmd->autoneg set to the link status (0) - phy_start_aneg() is called at the end of phy_ethtool_sset() and sets the PHY state to PHY_FORCING Just make sure we notify the interface carrier appropriately when we detect that the link is down in our fixed_link update callback. This is made local to the bcm_sf2 driver as the PHY library does the right thing in any case. This is similar to the GENET change introduced in 54d7c01d3ed699cfc213115eaecfe1175cfaff8f ("net: bcmgenet: enable MoCA link state change detection").

Currently the struct netvsc_stats has a member s_sync of type u64_stats_sync. This definition will break kernel build as the macro netdev_alloc_pcpu_stats requires this member name to be syncp.

Eric Dumazet says: ==================== tcp: better handling of memory pressure When testing commit 790ba4566c1a ("tcp: set SOCK_NOSPACE under memory pressure") using edge triggered epoll applications, I found various issues under memory pressure and thousands of active sockets. This patch series is a first round to solve these issues, in send and receive paths.

2015-05-17tcp: halves tcp_mem[] limitsEric Dumazet
Allowing tcp to use ~19% of physical memory is way too much, and allowed bugs to be hidden. Add to this that some drivers use a full page per incoming frame, so real cost can be twice the advertized one. Reduce tcp_mem by 50 % as a first step to sanity. tcp_mem[0,1,2] defaults are now 4.68%, 6.25%, 9.37% of physical memory. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2015-05-17tcp: allow one skb to be received per socket under memory pressureEric Dumazet
While testing tight tcp_mem settings, I found tcp sessions could be stuck because we do not allow even one skb to be received on them. By allowing one skb to be received, we introduce fairness and eventuallu force memory hogs to release their allocation. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
