WARN_ON_ONCE(pi_test_sn(&vmx->pi_desc)) in kvm_vcpu_trigger_posted_interrupt() intends to detect the violation of invariant that VT-d PI notification event is not suppressed when vcpu is in the guest mode. Because the two checks for the target vcpu mode and the target suppress field cannot be performed atomically, the target vcpu mode may change in between. If that does happen, WARN_ON_ONCE() here may raise false alarms. As the previous patch fixed the real invariant breaker, remove this WARN_ON_ONCE() to avoid false alarms, and document the allowed cases instead. Signed-off-by:

Haozhong Zhang authored
In kvm_vcpu_trigger_posted_interrupt() and pi_pre_block(), KVM assumes that PI notification events should not be suppressed when the target vCPU is not blocked. vmx_update_pi_irte() sets the SN field before changing an interrupt from posting to remapping, but it does not check the vCPU mode. Therefore, the change of SN field may break above the assumption. Besides, I don't see reasons to suppress notification events here, so remove the changes of SN field to avoid race condition.

This reverts commit 36ae3c0a. The commit broke compilation on !CONFIG_HAVE_KVM_IRQ_ROUTING. Also, there may be cases with CONFIG_HAVE_KVM_IRQ_ROUTING, where larger gsi values make sense. As the commit was meant as an early indicator to user space that something is wrong, reverting just restores the previous behavior where overly large values are ignored when encountered (without any direct feedback).

With the need to discourage use of less secure dialect, SMB1 (CIFS), we temporarily upgraded the dialect to SMB3 in 4.13, but since there are various servers which only support SMB2.1 (2.1 is more secure than CIFS/SMB1) but not optimal for a default dialect - add support for multidialect negotiation. cifs.ko will now request SMB2.1 or later (ie SMB2.1 or SMB3.0, SMB3.02) and the server will pick the latest most secure one it can support. In addition since we are sending multidialect negotiate, add support for secure negotiate to validate that a man in the middle didn't downgrade us. Signed-off-by:

The driver doesn't support events from address families other than IPv4 and IPv6, so ignore them. Otherwise, we risk queueing a work item before it's initialized. This can happen in case a VRF is configured when MROUTE_MULTIPLE_TABLES is enabled, as the VRF driver will try to add an l3mdev rule for the IPMR family.

sctp_diag would not actually dump out sk/asoc if inet_sctp_diag_fill returns err, in which case it shouldn't mark sk dumped by setting cb->args[3] as 1 in sctp_sock_dump(). Otherwise, it could cause some asocs to have no parent's sk dumped in 'ss --sctp'. So this patch is to not set cb->args[3] when inet_sctp_diag_fill() returns err in sctp_sock_dump().

Commit 86fdb344 ("sctp: ensure ep is not destroyed before doing the dump") tried to fix an use-after-free issue by checking !sctp_sk(sk)->ep with holding sock and sock lock. But Paolo noticed that endpoint could be destroyed in sctp_rcv without sock lock protection. It means the use-after-free issue still could be triggered when sctp_rcv put and destroy ep after sctp_sock_dump checks !ep, although it's pretty hard to reproduce. I could reproduce it by mdelay in sctp_rcv while msleep in sctp_close and sctp_sock_dump long time. This patch is to add another param cb_done to sctp_for_each_transport and dump ep->assocs with holding tsp after jumping out of transport's traversal in it to avoid this issue. It can also improve sctp diag dump to make it run faster, as no need to save sk into cb->args[5] and keep calling sctp_for_each_transport any more. This patch is also to use int * instead of int for the pos argument in sctp_for_each_transport, which could make postion increment only in sctp_for_each_transport and no need to keep changing cb->args[2] in sctp_sock_filter and sctp_sock_dump any more.

The default receive buffer size was reduced by recent change to a value which was appropriate for 10G and Windows Server 2016. But the value is too small for full performance with 40G on Azure.

liujian reported a problem in TCP_USER_TIMEOUT processing with a patch in tcp_probe_timer() : https://www.spinics.net/lists/netdev/msg454496.html After investigations, the root cause of the problem is that we update skb->skb_mstamp of skbs in write queue, even if the attempt to send a clone or copy of it failed. One reason being a routing problem. This patch prevents this, solving liujian issue. It also removes a potential RTT miscalculation, since __tcp_retransmit_skb() is not OR-ing TCP_SKB_CB(skb)->sacked with TCPCB_EVER_RETRANS if a failure happens, but skb->skb_mstamp has been changed. A future ACK would then lead to a very small RTT sample and min_rtt would then be lowered to this too small value. Tested: # cat user_timeout.pkt --local_ip=192.168.102.64 0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3 +0 setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0 +0 bind(3, ..., ...) = 0 +0 listen(3, 1) = 0 +0 `ifconfig tun0 192.168.102.64/16; ip ro add 192.0.2.1 dev tun0` +0 < S 0:0(0) win 0 <mss 1460> +0 > S. 0:0(0) ack 1 <mss 1460> +.1 < . 1:1(0) ack 1 win 65530 +0 accept(3, ..., ...) = 4 +0 setsockopt(4, SOL_TCP, TCP_USER_TIMEOUT, [3000], 4) = 0 +0 write(4, ..., 24) = 24 +0 > P. 1:25(24) ack 1 win 29200 +.1 < . 1:1(0) ack 25 win 65530 //change the ipaddress +1 `ifconfig tun0 192.168.0.10/16` +1 write(4, ..., 24) = 24 +1 write(4, ..., 24) = 24 +1 write(4, ..., 24) = 24 +1 write(4, ..., 24) = 24 +0 `ifconfig tun0 192.168.102.64/16` +0 < . 1:2(1) ack 25 win 65530 +0 `ifconfig tun0 192.168.0.10/16` +3 write(4, ..., 24) = -1 # ./packetdrill user_timeout.pkt Signed-off-by:

Commit 0a1eb2d4 ("fs/proc: Stop reporting eip and esp in /proc/PID/stat") stopped reporting eip/esp because it is racy and dangerous for executing tasks. The comment adds: As far as I know, there are no use programs that make any material use of these fields, so just get rid of them. However, existing userspace core-dump-handler applications (for example, minicoredumper) are using these fields since they provide an excellent cross-platform interface to these valuable pointers. So that commit introduced a user space visible regression. Partially revert the change and make the readout possible for tasks with the proper permissions and only if the target task has the PF_DUMPCORE flag set.

rt_iif is only set to the actual egress device for the output path. The recent change to consider the l3slave flag when returning IP_PKTINFO works for local traffic (the correct device index is returned), but it broke the more typical use case of packets received from a remote host always returning the VRF index rather than the original ingress device. Update the fixup to consider l3slave and rt_iif actually getting set. Fixes: 1dfa7639 ("net: ipv4: add check for l3slave for index returned in IP_PKTINFO") Signed-off-by:
