2017-12-20tipc: remove joining group member from congested listJon Maloy
When we receive a JOIN message from a peer member, the message may contain an advertised window value ADV_IDLE that permits removing the member in question from the tipc_group::congested list. However, since the removal has been made conditional on that the advertised window is *not* ADV_IDLE, we miss this case. This has the effect that a sender sometimes may enter a state of permanent, false, broadcast congestion. We fix this by unconditinally removing the member from the congested list before calling tipc_member_update(), which might potentially sort it into the list again.

Yafang Shao says: ==================== replace tcp_set_state tracepoint with inet_sock_set_state According to the discussion in the mail thread https://patchwork.kernel.org/patch/10099243/, tcp_set_state tracepoint is renamed to inet_sock_set_state tracepoint and is moved to include/trace/events/sock.h. With this new tracepoint, we can trace AF_INET/AF_INET6 sock state transitions. As there's only one single tracepoint for inet, so I didn't create a new trace file named trace/events/inet_sock.h, and just place it in include/trace/events/sock.h Currently TCP/DCCP/SCTP state transitions are traced with this tracepoint. - Why not more protocol ? If we really think that anonter protocol should be traced, I will modify the code to trace it. I just want to make the code easy and not output useless information. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2017-12-20net: tracepoint: using sock_set_state tracepoint to trace SCTP state transitionYafang Shao
With changes in inet_ files, SCTP state transitions are traced with inet_sock_set_state tracepoint. As SCTP state names, i.e. SCTP_SS_CLOSED, SCTP_SS_ESTABLISHED, have the same value with TCP state names. So the output info still print the TCP state names, that makes the code easy.

2017-12-20net: tracepoint: replace tcp_set_state tracepoint with inet_sock_set_state ↵Yafang Shao
tracepoint As sk_state is a common field for struct sock, so the state transition tracepoint should not be a TCP specific feature. Currently it traces all AF_INET state transition, so I rename this tracepoint to inet_sock_set_state tracepoint with some minor changes and move it into trace/events/sock.h. We dont need to create a file named trace/events/inet_sock.h for this one single tracepoint. Two helpers are introduced to trace sk_state transition - void inet_sk_state_store(struct sock *sk, int newstate); - void inet_sk_set_state(struct sock *sk, int state); As trace header should not be included in other header files, so they are defined in sock.c. The protocol such as SCTP maybe compiled as a ko, hence export inet_sk_set_state(). Signed-off-by: Yafang Shao <laoar.shao@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-12-20tcp: Export to userspace the TCP state names for the trace eventsSteven Rostedt (VMware)
The TCP trace events (specifically tcp_set_state), maps emums to symbol names via __print_symbolic(). But this only works for reading trace events from the tracefs trace files. If perf or trace-cmd were to record these events, the event format file does not convert the enum names into numbers, and you get something like: __print_symbolic(REC->oldstate, { TCP_ESTABLISHED, "TCP_ESTABLISHED" }, { TCP_SYN_SENT, "TCP_SYN_SENT" }, { TCP_SYN_RECV, "TCP_SYN_RECV" }, { TCP_FIN_WAIT1, "TCP_FIN_WAIT1" }, { TCP_FIN_WAIT2, "TCP_FIN_WAIT2" }, { TCP_TIME_WAIT, "TCP_TIME_WAIT" }, { TCP_CLOSE, "TCP_CLOSE" }, { TCP_CLOSE_WAIT, "TCP_CLOSE_WAIT" }, { TCP_LAST_ACK, "TCP_LAST_ACK" }, { TCP_LISTEN, "TCP_LISTEN" }, { TCP_CLOSING, "TCP_CLOSING" }, { TCP_NEW_SYN_RECV, "TCP_NEW_SYN_RECV" }) Where trace-cmd and perf do not know the values of those enums. Use the TRACE_DEFINE_ENUM() macros that will have the trace events convert the enum strings into their values at system boot. This will allow perf and trace-cmd to see actual numbers and not enums: __print_symbolic(REC->oldstate, { 1, "TCP_ESTABLISHED" }, { 2, "TCP_SYN_SENT" }, { 3, "TCP_SYN_RECV" }, { 4, "TCP_FIN_WAIT1" }, { 5, "TCP_FIN_WAIT2" }, { 6, "TCP_TIME_WAIT" }, { 7, "TCP_CLOSE" }, { 8, "TCP_CLOSE_WAIT" }, { 9, "TCP_LAST_ACK" }, { 10, "TCP_LISTEN" }, { 11, "TCP_CLOSING" }, { 12, "TCP_NEW_SYN_RECV" }) Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org> Acked-by: Song Liu <songliubraving@fb.com> Signed-off-by: Yafang Shao <laoar.shao@gmail.com> Signed-off-by: David S.

2017-12-20block-throttle: avoid double chargeShaohua Li
If a bio is throttled and split after throttling, the bio could be resubmited and enters the throttling again. This will cause part of the bio to be charged multiple times. If the cgroup has an IO limit, the double charge will significantly harm the performance. The bio split becomes quite common after arbitrary bio size change. To fix this, we always set the BIO_THROTTLED flag if a bio is throttled. If the bio is cloned/split, we copy the flag to new bio too to avoid a double charge. However, cloned bio could be directed to a new disk, keeping the flag be a problem. The observation is we always set new disk for the bio in this case, so we can clear the flag in bio_set_dev(). This issue exists for a long time, arbitrary bio size change just makes it worse, so this should go into stable at least since v4.2.

cls_bpf used to take care of tracking what offload state a filter is in, i.e. it would track if offload request succeeded or not. This information would then be used to issue correct requests to the driver, e.g. requests for statistics only on offloaded filters, removing only filters which were offloaded, using add instead of replace if previous filter was not added etc. This tracking of offload state no longer functions with the new callback infrastructure. There could be multiple entities trying to offload the same filter. Throw out all the tracking and corresponding commands and simply pass to the drivers both old and new bpf program. Drivers will have to deal with offload state tracking by themselves.

2017-12-20net: Fix double free and memory corruption in get_net_ns_by_id()Eric W. Biederman
(I can trivially verify that that idr_remove in cleanup_net happens after the network namespace count has dropped to zero --EWB) Function get_net_ns_by_id() does not check for net::count after it has found a peer in netns_ids idr. It may dereference a peer, after its count has already been finaly decremented. This leads to double free and memory corruption: put_net(peer) rtnl_lock() atomic_dec_and_test(&peer->count) [count=0] ... __put_net(peer) get_net_ns_by_id(net, id) spin_lock(&cleanup_list_lock) list_add(&net->cleanup_list, &cleanup_list) spin_unlock(&cleanup_list_lock) queue_work() peer = idr_find(&net->netns_ids, id) | get_net(peer) [count=1] | ... | (use after final put) v ... cleanup_net() ... spin_lock(&cleanup_list_lock) ... list_replace_init(&cleanup_list, ..) ... spin_unlock(&cleanup_list_lock) ... ... ... ... put_net(peer) ... atomic_dec_and_test(&peer->count) [count=0] ... spin_lock(&cleanup_list_lock) ... list_add(&net->cleanup_list, &cleanup_list) ... spin_unlock(&cleanup_list_lock) ... queue_work() ... rtnl_unlock() rtnl_lock() ... for_each_net(tmp) { ... id = __peernet2id(tmp, peer) ... spin_lock_irq(&tmp->nsid_lock) ... idr_remove(&tmp->netns_ids, id) ... ... ... net_drop_ns() ... net_free(peer) ... } ... | v cleanup_net() ... (Second free of peer) Also, put_net() on the right cpu may reorder with left's cpu list_replace_init(&cleanup_list, ..), and then cleanup_list will be corrupted. Since cleanup_net() is executed in worker thread, while put_net(peer) can happen everywhere, there should be enough time for concurrent get_net_ns_by_id() to pick the peer up, and the race does not seem to be unlikely. The patch fixes the problem in standard way. (Also, there is possible problem in peernet2id_alloc(), which requires check for net::count under nsid_lock and maybe_get_net(peer), but in current stable kernel it's used under rtnl_lock() and it has to be safe. Openswitch begun to use peernet2id_alloc(), and possibly it should be fixed too. While this is not in stable kernel yet, so I'll send a separate message to netdev@ later).

2017-12-20ip6_vti: adjust vti mtu according to mtu of lower deviceAlexey Kodanev
LTP/udp6_ipsec_vti tests fail when sending large UDP datagrams over ip6_vti that require fragmentation and the underlying device has an MTU smaller than 1500 plus some extra space for headers. This happens because ip6_vti, by default, sets MTU to ETH_DATA_LEN and not updating it depending on a destination address or link parameter. Further attempts to send UDP packets may succeed because pmtu gets updated on ICMPV6_PKT_TOOBIG in vti6_err(). In case the lower device has larger MTU size, e.g. 9000, ip6_vti works but not using the possible maximum size, output packets have 1500 limit. The above cases require manual MTU setup after ip6_vti creation. However ip_vti already updates MTU based on lower device with ip_tunnel_bind_dev(). Here is the example when the lower device MTU is set to 9000: # ip a sh ltp_ns_veth2 ltp_ns_veth2@if7: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 ... inet 10.0.0.2/24 scope global ltp_ns_veth2 inet6 fd00::2/64 scope global # ip li add vti6 type vti6 local fd00::2 remote fd00::1 # ip li show vti6 vti6@NONE: <POINTOPOINT,NOARP> mtu 1500 ... link/tunnel6 fd00::2 peer fd00::1 After the patch: # ip li add vti6 type vti6 local fd00::2 remote fd00::1 # ip li show vti6 vti6@NONE: <POINTOPOINT,NOARP> mtu 8832 ... link/tunnel6 fd00::2 peer fd00::1 Reported-by: Petr Vorel <pvorel@suse.cz> Signed-off-by: Alexey Kodanev <alexey.kodanev@oracle.com> Signed-off-by: David S.

The hashing of %p was designed to restrict kernel addresses. There is no reason to hash the userspace values seen during a segfault report, so switch these to %px. (Some architectures already use %lx.)

2017-12-20libbpf: Fix build errors.David Miller
These elf object pieces are of type Elf64_Xword and therefore could be "long long" on some builds. Cast to "long long" and use printf format %lld to deal with this since we are building with -Werror=format. Signed-off-by: David S.

2017-12-20bpf: Fix tools and testing build.David Miller
I'm getting various build failures on sparc64. The key is usually that the userland tools get built 32-bit. 1) clock_gettime() is in librt, so that must be added to the link libraries. 2) "sizeof(x)" must be printed with "%Z" printf prefix.

2017-12-19net/mlx5: Stay in polling mode when command EQ destroy failsMoshe Shemesh
During unload, on mlx5_stop_eqs we move command interface from events mode to polling mode, but if command interface EQ destroy fail we move back to events mode. That's wrong since even if we fail to destroy command interface EQ, we do release its irq, so no interrupts will be received.

2017-12-19net/mlx5: Cleanup IRQs in case of unload failureMoshe Shemesh
When mlx5_stop_eqs fails to destroy any of the eqs it returns with an error. In such failure flow the function will return without releasing all EQs irqs and then pci_free_irq_vectors will fail. Fix by only warn on destroy EQ failure and continue to release other EQs and their irqs. It fixes the following kernel trace: kernel: kernel BUG at drivers/pci/msi.c:352! ... ... kernel: Call Trace: kernel: pci_disable_msix+0xd3/0x100 kernel: pci_free_irq_vectors+0xe/0x20 kernel: mlx5_load_one.isra.17+0x9f5/0xec0 [mlx5_core] Fixes: e126ba97dba9 ("mlx5: Add driver for Mellanox Connect-IB adapters") Signed-off-by: Moshe Shemesh <moshe@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

Flow steering priority and namespace are software only objects that didn't have the proper destructors and were not freed during steering cleanup.

2017-12-19net/mlx5e: Prevent possible races in VXLAN control flowGal Pressman
When calling add/remove VXLAN port, a lock must be held in order to prevent race scenarios when more than one add/remove happens at the same time. Fix by holding our state_lock (mutex) as done by all other parts of the driver. Note that the spinlock protecting the radix-tree is still needed in order to synchronize radix-tree access from softirq context.
