Until now, we create timers even for the subscription requests with timeout = TIPC_WAIT_FOREVER. This can be improved by avoiding timer creation when the timeout is set to TIPC_WAIT_FOREVER. In this commit, we introduce a check to creates timers only when timeout != TIPC_WAIT_FOREVER. Acked-by:

Until now, during subscription creation the mod_time() & tipc_subscrb_get() are called after releasing the subscriber spin lock. In a SMP system when performing a subscription creation, if the subscription timeout occurs simultaneously (the timer is scheduled to run on another CPU) then the timer thread might decrement the subscribers refcount before the create thread increments the refcount. This can be simulated by creating subscription with timeout=0 and sometimes the timeout occurs before the create request is complete. This leads to the following message: [30.702949] BUG: spinlock bad magic on CPU#1, kworker/u8:3/87 [30.703834] general protection fault: 0000 [#1] SMP [30.704826] CPU: 1 PID: 87 Comm: kworker/u8:3 Not tainted 4.4.0-rc8+ #18 [30.704826] Workqueue: tipc_rcv tipc_recv_work [tipc] [30.704826] task: ffff88003f878600 ti: ffff88003fae0000 task.ti: ffff88003fae0000 [30.704826] RIP: 0010:[<ffffffff8109196c>] [<ffffffff8109196c>] spin_dump+0x5c/0xe0 [...] [30.704826] Call Trace: [30.704826] [<ffffffff81091a16>] spin_bug+0x26/0x30 [30.704826] [<ffffffff81091b75>] do_raw_spin_lock+0xe5/0x120 [30.704826] [<ffffffff81684439>] _raw_spin_lock_bh+0x19/0x20 [30.704826] [<ffffffffa0096f10>] tipc_subscrb_rcv_cb+0x1d0/0x330 [tipc] [30.704826] [<ffffffffa00a37b1>] tipc_receive_from_sock+0xc1/0x150 [tipc] [30.704826] [<ffffffffa00a31df>] tipc_recv_work+0x3f/0x80 [tipc] [30.704826] [<ffffffff8106a739>] process_one_work+0x149/0x3c0 [30.704826] [<ffffffff8106aa16>] worker_thread+0x66/0x460 [30.704826] [<ffffffff8106a9b0>] ? process_one_work+0x3c0/0x3c0 [30.704826] [<ffffffff8106a9b0>] ? process_one_work+0x3c0/0x3c0 [30.704826] [<ffffffff8107029d>] kthread+0xed/0x110 [30.704826] [<ffffffff810701b0>] ? kthread_create_on_node+0x190/0x190 [30.704826] [<ffffffff81684bdf>] ret_from_fork+0x3f/0x70 In this commit, 1. we remove the check for the return code for mod_timer() 2. we protect tipc_subscrb_get() using the subscriber spin lock.

Until now, while creating a subscription the subscriber lock protects only the subscribers subscription list and not the nametable. The call to tipc_nametbl_subscribe() is outside the lock. However, at subscription timeout and cancel both the subscribers subscription list and the nametable are protected by the subscriber lock. This asymmetric locking mechanism leads to the following problem: In a SMP system, the timer can be fire on another core before the create request is complete. When the timer thread calls tipc_nametbl_unsubscribe() before create thread calls tipc_nametbl_subscribe(), we get a nullptr exception. This can be simulated by creating subscription with timeout=0 and sometimes the timeout occurs before the create request is complete. The following is the oops: [57.569661] BUG: unable to handle kernel NULL pointer dereference at (null) [57.577498] IP: [<ffffffffa02135aa>] tipc_nametbl_unsubscribe+0x8a/0x120 [tipc] [57.584820] PGD 0 [57.586834] Oops: 0002 [#1] SMP [57.685506] CPU: 14 PID: 10077 Comm: kworker/u40:1 Tainted: P OENX 3.12.48-52.27.1. 9688.1.PTF-default #1 [57.703637] Workqueue: tipc_rcv tipc_recv_work [tipc] [57.708697] task: ffff88064c7f00c0 ti: ffff880629ef4000 task.ti: ffff880629ef4000 [57.716181] RIP: 0010:[<ffffffffa02135aa>] [<ffffffffa02135aa>] tipc_nametbl_unsubscribe+0x8a/ 0x120 [tipc] [...] [57.812327] Call Trace: [57.814806] [<ffffffffa0211c77>] tipc_subscrp_delete+0x37/0x90 [tipc] [57.821357] [<ffffffffa0211e2f>] tipc_subscrp_timeout+0x3f/0x70 [tipc] [57.827982] [<ffffffff810618c1>] call_timer_fn+0x31/0x100 [57.833490] [<ffffffff81062709>] run_timer_softirq+0x1f9/0x2b0 [57.839414] [<ffffffff8105a795>] __do_softirq+0xe5/0x230 [57.844827] [<ffffffff81520d1c>] call_softirq+0x1c/0x30 [57.850150] [<ffffffff81004665>] do_softirq+0x55/0x90 [57.855285] [<ffffffff8105aa35>] irq_exit+0x95/0xa0 [57.860290] [<ffffffff815215b5>] smp_apic_timer_interrupt+0x45/0x60 [57.866644] [<ffffffff8152005d>] apic_timer_interrupt+0x6d/0x80 [57.872686] [<ffffffffa02121c5>] tipc_subscrb_rcv_cb+0x2a5/0x3f0 [tipc] [57.879425] [<ffffffffa021c65f>] tipc_receive_from_sock+0x9f/0x100 [tipc] [57.886324] [<ffffffffa021c826>] tipc_recv_work+0x26/0x60 [tipc] [57.892463] [<ffffffff8106fb22>] process_one_work+0x172/0x420 [57.898309] [<ffffffff8107079a>] worker_thread+0x11a/0x3c0 [57.903871] [<ffffffff81077114>] kthread+0xb4/0xc0 [57.908751] [<ffffffff8151f318>] ret_from_fork+0x58/0x90 In this commit, we do the following at subscription creation: 1. set the subscription's subscriber pointer before performing tipc_nametbl_subscribe(), as this value is required further in the call chain ex: by tipc_subscrp_send_event(). 2. move tipc_nametbl_subscribe() under the scope of subscriber lock Acked-by:

Until now, the subscribers endianness for a subscription create/cancel request is determined as: swap = !(s->filter & (TIPC_SUB_PORTS | TIPC_SUB_SERVICE)) The checks are performed only for port/service subscriptions. The swap calculation is incorrect if the filter in the subscription cancellation request is set to TIPC_SUB_CANCEL (it's a malformed cancel request, as the corresponding subscription create filter is missing). Thus, the check if the request is for cancellation fails and the request is treated as a subscription create request. The subscription creation fails as the request is illegal, which terminates this connection. In this commit we determine the endianness by including TIPC_SUB_CANCEL, which will set swap correctly and the request is processed as a cancellation request. Acked-by: -

In 'commit 7fe8097c ("tipc: fix nullpointer bug when subscribing to events")', we terminate the connection if the subscription creation fails. In the same commit, the subscription creation result was based on the value of subscription pointer (set in the function) instead of the return code. Unfortunately, the same function also handles subscription cancellation request. For a subscription cancellation request, the subscription pointer cannot be set. Thus the connection is terminated during cancellation request. In this commit, we move the subcription cancel check outside of tipc_subscrp_create(). Hence, - tipc_subscrp_create() will create a subscripton - tipc_subscrb_rcv_cb() will subscribe or cancel a subscription.

In this commit, we split tipc_subscrp_create() into two: 1. tipc_subscrp_create() creates a subscription 2. A new function tipc_subscrp_subscribe() adds the subscription to the subscriber subscription list, activates the subscription timer and subscribes to the nametable updates. In future commits, the purpose of tipc_subscrb_rcv_cb() will be to either subscribe or cancel a subscription. There is no functional change in this commit. Acked-by:

Until now, struct tipc_subscriber has duplicate fields for type, upper and lower (as member of struct tipc_name_seq) at: 1. as member seq in struct tipc_subscription 2. as member seq in struct tipc_subscr, which is contained in struct tipc_event The former structure contains the type, upper and lower values in network byte order and the later contains the intact copy of the request. The struct tipc_subscription contains a field swap to determine if request needs network byte order conversion. Thus by using swap, we can convert the request when required instead of duplicating it. In this commit, 1. we remove the references to these elements as members of struct tipc_subscription and replace them with elements from struct tipc_subscr. 2. provide new functions to convert the user request into network byte order.

Until now, during subscription creation we set sub->timeout by converting the timeout request value in milliseconds to jiffies. This is followed by setting the timeout value in the timer if sub->timeout != TIPC_WAIT_FOREVER. For a subscription create request with a timeout value of TIPC_WAIT_FOREVER, msecs_to_jiffies(TIPC_WAIT_FOREVER) returns MAX_JIFFY_OFFSET (0xfffffffe). This is not equal to TIPC_WAIT_FOREVER (0xffffffff). In this commit, we remove this check. Acked-by:

Alexei Starovoitov says: ==================== bpf: introduce per-cpu maps We've started to use bpf to trace every packet and atomic add instruction (event JITed) started to show up in perf profile. The solution is to do per-cpu counters. For PERCPU_(HASH|ARRAY) map the existing bpf_map_lookup() helper returns per-cpu area which bpf programs can use to store and increment the counters. The BPF_MAP_LOOKUP_ELEM syscall command returns areas from all cpus and user process aggregates the counters. The usage example is in patch 6. The api turned out to be very easy to use from bpf program and from user space. Long term we were discussing to add 'bounded loop' instruction, so bpf programs can do aggregation within the program which may help some use cases. Right now user space aggregation of per-cpu counters fits the best. This patch set is new approach for per-cpu hash and array maps. I've reused the map tests written by Martin and Ming, but implementation and api is new.

The functions bpf_map_lookup_elem(map, key, value) and bpf_map_update_elem(map, key, value, flags) need to get/set values from all-cpus for per-cpu hash and array maps, so that user space can aggregate/update them as necessary. Example of single counter aggregation in user space: unsigned int nr_cpus = sysconf(_SC_NPROCESSORS_CONF); long values[nr_cpus]; long value = 0; bpf_lookup_elem(fd, key, values); for (i = 0; i < nr_cpus; i++) value += values[i]; The user space must provide round_up(value_size, 8) * nr_cpus array to get/set values, since kernel will use 'long' copy of per-cpu values to try to copy good counters atomically. It's a best-effort, since bpf programs and user space are racing to access the same memory. Signed-off-by: -

Primary use case is a histogram array of latency where bpf program computes the latency of block requests or other events and stores histogram of latency into array of 64 elements. All cpus are constantly running, so normal increment is not accurate, bpf_xadd causes cache ping-pong and this per-cpu approach allows fastest collision-free counters. Signed-off-by:

Introduce BPF_MAP_TYPE_PERCPU_HASH map type which is used to do accurate counters without need to use BPF_XADD instruction which turned out to be too costly for high-performance network monitoring. In the typical use case the 'key' is the flow tuple or other long living object that sees a lot of events per second. bpf_map_lookup_elem() returns per-cpu area. Example: struct { u32 packets; u32 bytes; } * ptr = bpf_map_lookup_elem(&map, &key); /* ptr points to this_cpu area of the value, so the following * increments will not collide with other cpus */ ptr->packets ++; ptr->bytes += skb->len; bpf_update_elem() atomically creates a new element where all per-cpu values are zero initialized and this_cpu value is populated with given 'value'. Note that non-per-cpu hash map always allocates new element and then deletes old after rcu grace period to maintain atomicity of update. Per-cpu hash map updates element values in-place.

RFC 7413 (TCP Fast Open) 4.2.2 states that the SYNACK message MAY include data and/or FIN This patch adds support for the client side : If we receive a SYNACK with payload or FIN, queue the skb instead of ignoring it. Since we already support the same for SYN, we refactor the existing code and reuse it. Note we need to clone the skb, so this operation might fail under memory pressure. Sara Dickinson pointed out FreeBSD server Fast Open implementation was planned to generate such SYNACK in the future. The server side might be implemented on linux later. Reported-by:

Jarod Wilson says: ==================== net: add and use rx_nohandler stat counter The network core tries to keep track of dropped packets, but some packets you wouldn't really call dropped, so much as intentionally ignored, under certain circumstances. One such case is that of bonding and team device slaves that are currently inactive. Their respective rx_handler functions return RX_HANDLER_EXACT (the only places in the kernel that return that), which ends up tracking into the network core's __netif_receive_skb_core() function's drop path, with no pt_prev set. On a noisy network, this can result in a very rapidly incrementing rx_dropped counter, not only on the inactive slave(s), but also on the master device, such as the following: $ cat /proc/net/dev Inter-| Receive | Transmit face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed p7p1: 14783346 140430 0 140428 0 0 0 2040 680 8 0 0 0 0 0 0 p7p2: 14805198 140648 0 0 0 0 0 2034 0 0 0 0 0 0 0 0 bond0: 53365248 532798 0 421160 0 0 0 115151 2040 24 0 0 0 0 0 0 lo: 5420 54 0 0 0 0 0 0 5420 54 0 0 0 0 0 0 p5p1: 19292195 196197 0 140368 0 0 0 56564 680 8 0 0 0 0 0 0 p5p2: 19289707 196171 0 140364 0 0 0 56547 680 8 0 0 0 0 0 0 em3: 20996626 158214 0 0 0 0 0 383 0 0 0 0 0 0 0 0 em2: 14065122 138462 0 0 0 0 0 310 0 0 0 0 0 0 0 0 em1: 14063162 138440 0 0 0 0 0 308 0 0 0 0 0 0 0 0 em4: 21050830 158729 0 0 0 0 0 385 71662 469 0 0 0 0 0 0 ib0: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 In this scenario, p5p1, p5p2 and p7p1 are all inactive slaves in an active-backup bond0, and you can see that all three have high drop counts, with the master bond0 showing a tally of all three. I know that this was previously discussed some here: http://www.spinics.net/lists/netdev/msg226341.html It seems additional counters never came to fruition, so this is a first attempt at creating one of them, so that we stop calling these drops, which for users monitoring rx_dropped, causes great alarm, and renders the counter much less useful for them. This adds a sysfs statistics node and makes the counter available via netlink. Additionally, I'm not certain if this set qualifies for net, or if it should be put aside and resubmitted for net-next after 4.5 is put to bed, but I do have users who consider this an important bugfix. This has been tested quite a bit on x86_64, and now lightly on i686 as well, to verify functionality of updates to netdev_stats_to_stats64() on 32-bit arches. ==================== Signed-off-by:Jarod Wilson <jarod@redhat.com> Signed-off-by:

Richard Alpe authored
Changing certain link attributes (link tolerance and link priority) from the TIPC management tool is supposed to automatically take effect at both endpoints of the affected link. Currently the media address is not instantiated for the link and is used uninstantiated when crafting protocol messages designated for the peer endpoint. This means that changing a link property currently results in the property being changed on the local machine but the protocol message designated for the peer gets lost. Resulting in property discrepancy between the endpoints. In this patch we resolve this by using the media address from the link entry and using the bearer transmit function to send it. Hence, we can now eliminate the redundant function tipc_link_prot_xmit() and the redundant field tipc_link::media_addr. Fixes: 2af5ae37 (tipc: clean up unused code and structures) Reviewed-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-02-03 This series contains updates to i40e and i40evf only. Kiran adds the MAC filter element to the end of the list instead of HEAD just in case there are ever any ordering issues in the future. Anjali fixes several RSS issues, first fixes the hash PCTYPE enable for X722 since it supports a broader selection of PCTYPES for TCP and UDP. Then fixes a bug in XL710, X710, and X722 support for RSS since we cannot reduce the 4-tuple for RSS for TCP/IPv4/IPv6 or UDP/IPv4/IPv6 packets since this requires a product feature change coming in a later release. Cleans up the reset code where the restart-autoneg workaround is applied, since X722 does not need the workaround, add a flag to indicate which MAC and firmware version require the workaround to be applied. Adds new device id's for X722 and code to add their support. Also adds another way to access the RSS keys and lookup table using the admin queue for X722 devices. Catherine updates the driver to replace the MAC check with a feature flag check for 100M SGMII, since it is only support on X722 devices currently. Mitch reworks the VF driver to allow channel bonding, which was not possible before this patch due to the asynchronous nature of the admin queue mechanism. Also fixes a rare case which causes a panic if the VF driver is removed during reset recovery, resolve this by setting the ring pointers to NULL after freeing them. Shannon cleans up the driver where device capabilities were defined in two different places, and neither had all the definitions, so he consolidates the definitions in the admin queue API. Also adds the new proxy-wake-on-lan capability bit available with the new X722 device. Lastly, added the new External Device Power Ability field to the get_link_status data structure by using a reserved field at the end of the structure. Jesse mimics the ixgbe driver's use of a private work queue in the i40e and i40evf drivers to avoid blocking the system work queue. Greg cleans up the driver to limit the firmware revision checks to properly handle DCB configurations from the firmware to the older devices which need these checks (specifically X710 and XL710 devices only). ==================== Signed-off-by:

When we create IPvlan slave; we use ether_setup() and that sets up default MTU to 1500 while the master device may have lower / different MTU. Any subsequent changes to the masters' MTU are reflected into the slaves' MTU setting. However if those don't happen (most likely scenario), the slaves' MTU stays at 1500 which could be bad. This change adds code to inherit MTU from the master device instead of using the default value during the link initialization phase. Signed-off-by:
