| 2019-12-16 | vsock/virtio: fix null-pointer dereference in virtio_transport_recv_listen() | Stefano Garzarella | |
| With multi-transport support, listener sockets are not bound to any transport. So, calling virtio_transport_reset(), when an error occurs, on a listener socket produces the following null-pointer dereference: BUG: kernel NULL pointer dereference, address: 00000000000000e8 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [#1] SMP PTI CPU: 0 PID: 20 Comm: kworker/0:1 Not tainted 5.5.0-rc1-ste-00003-gb4be21f316ac-dirty #56 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS ?-20190727_073836-buildvm-ppc64le-16.ppc.fedoraproject.org-3.fc31 04/01/2014 Workqueue: virtio_vsock virtio_transport_rx_work [vmw_vsock_virtio_transport] RIP: 0010:virtio_transport_send_pkt_info+0x20/0x130 [vmw_vsock_virtio_transport_common] Code: 1f 84 00 00 00 00 00 0f 1f 00 55 48 89 e5 41 57 41 56 41 55 49 89 f5 41 54 49 89 fc 53 48 83 ec 10 44 8b 76 20 e8 c0 ba fe ff <48> 8b 80 e8 00 00 00 e8 64 e3 7d c1 45 8b 45 00 41 8b 8c 24 d4 02 RSP: 0018:ffffc900000b7d08 EFLAGS: 00010282 RAX: 0000000000000000 RBX: ffff88807bf12728 RCX: 0000000000000000 RDX: ffff88807bf12700 RSI: ffffc900000b7d50 RDI: ffff888035c84000 RBP: ffffc900000b7d40 R08: ffff888035c84000 R09: ffffc900000b7d08 R10: ffff8880781de800 R11: 0000000000000018 R12: ffff888035c84000 R13: ffffc900000b7d50 R14: 0000000000000000 R15: ffff88807bf12724 FS: 0000000000000000(0000) GS:ffff88807dc00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00000000000000e8 CR3: 00000000790f4004 CR4: 0000000000160ef0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: virtio_transport_reset+0x59/0x70 [vmw_vsock_virtio_transport_common] virtio_transport_recv_pkt+0x5bb/0xe50 [vmw_vsock_virtio_transport_common] ? detach_buf_split+0xf1/0x130 virtio_transport_rx_work+0xba/0x130 [vmw_vsock_virtio_transport] process_one_work+0x1c0/0x300 worker_thread+0x45/0x3c0 kthread+0xfc/0x130 ? current_work+0x40/0x40 ? kthread_park+0x90/0x90 ret_from_fork+0x35/0x40 Modules linked in: sunrpc kvm_intel kvm vmw_vsock_virtio_transport vmw_vsock_virtio_transport_common irqbypass vsock virtio_rng rng_core CR2: 00000000000000e8 ---[ end trace e75400e2ea2fa824 ]--- This happens because virtio_transport_reset() calls virtio_transport_send_pkt_info() that can be used only on connecting/connected sockets.

| 2019-12-15 | tcp: Set rcv zerocopy hint correctly if skb last frag is < PAGE_SIZE | Arjun Roy | |
| At present, if the last frag of paged data in a skb has < PAGE_SIZE data, we compute the recv_skip_hint as being equal to the size of that frag and the entire next skb. Instead, just return the runt frag size as the hint. recv_skip_hint is used by the application to skip over bytes that can not be mmaped, so returning a too big chunk is pessimistic and forces more bytes to be copied.

| 2019-12-15 | net/smc: add fallback check to connect() | Ursula Braun | |
| FASTOPEN setsockopt() or sendmsg() may switch the SMC socket to fallback mode. Once fallback mode is active, the native TCP socket functions are called. Nevertheless there is a small race window, when FASTOPEN setsockopt/sendmsg runs in parallel to a connect(), and switch the socket into fallback mode before connect() takes the sock lock. Make sure the SMC-specific connect setup is omitted in this case. This way a syzbot-reported refcount problem is fixed, triggered by different threads running non-blocking connect() and FASTOPEN_KEY setsockopt.

| 2019-12-13 | tcp: refine rule to allow EPOLLOUT generation under mem pressure | Eric Dumazet | |
| At the time commit ce5ec440994b ("tcp: ensure epoll edge trigger wakeup when write queue is empty") was added to the kernel, we still had a single write queue, combining rtx and write queues. Once we moved the rtx queue into a separate rb-tree, testing if sk_write_queue is empty has been suboptimal. Indeed, if we have packets in the rtx queue, we probably want to delay the EPOLLOUT generation at the time incoming packets will free them, making room, but more importantly avoiding flooding application with EPOLLOUT events. Solution is to use tcp_rtx_and_write_queues_empty() helper.

| 2019-12-13 | tcp: refine tcp_write_queue_empty() implementation | Eric Dumazet | |
| Due to how tcp_sendmsg() is implemented, we can have an empty skb at the tail of the write queue. Most [1] tcp_write_queue_empty() callers want to know if there is anything to send (payload and/or FIN) Instead of checking if the sk_write_queue is empty, we need to test if tp->write_seq == tp->snd_nxt [1] tcp_send_fin() was the only caller that expected to see if an skb was in the write queue, I have changed the code to reuse the tcp_write_queue_tail() result.

| 2019-12-13 | tcp: do not send empty skb from tcp_write_xmit() | Eric Dumazet | |
| Backport of commit fdfc5c8594c2 ("tcp: remove empty skb from write queue in error cases") in linux-4.14 stable triggered various bugs. One of them has been fixed in commit ba2ddb43f270 ("tcp: Don't dequeue SYN/FIN-segments from write-queue"), but we still have crashes in some occasions. Root-cause is that when tcp_sendmsg() has allocated a fresh skb and could not append a fragment before being blocked in sk_stream_wait_memory(), tcp_write_xmit() might be called and decide to send this fresh and empty skb. Sending an empty packet is not only silly, it might have caused many issues we had in the past with tp->packets_out being out of sync.

| 2019-12-13 | tcp/dccp: fix possible race __inet_lookup_established() | Eric Dumazet | |
| Michal Kubecek and Firo Yang did a very nice analysis of crashes happening in __inet_lookup_established(). Since a TCP socket can go from TCP_ESTABLISH to TCP_LISTEN (via a close()/socket()/listen() cycle) without a RCU grace period, I should not have changed listeners linkage in their hash table. They must use the nulls protocol (Documentation/RCU/rculist_nulls.txt), so that a lookup can detect a socket in a hash list was moved in another one. Since we added code in commit d296ba60d8e2 ("soreuseport: Resolve merge conflict for v4/v6 ordering fix"), we have to add hlist_nulls_add_tail_rcu() helper.

| 2019-12-13 | mac80211: Turn AQL into an NL80211_EXT_FEATURE | Toke Høiland-Jørgensen | |
| Instead of just having an airtime flag in debugfs, turn AQL into a proper NL80211_EXT_FEATURE, so drivers can turn it on when they are ready, and so we also expose the presence of the feature to userspace. This also has the effect of flipping the default, so drivers have to opt in to using AQL instead of getting it by default with TXQs. To keep functionality the same as pre-patch, we set this feature for ath10k (which is where it is needed the most). While we're at it, split out the debugfs interface so AQL gets its own per-station debugfs file instead of using the 'airtime' file. [Johannes:] This effectively disables AQL for iwlwifi, where it fixes a number of issues: * TSO in iwlwifi is causing underflows and associated warnings in AQL * HE (802.11ax) rates aren't reported properly so at HE rates, AQL could never have a valid estimate (it'd use 6 Mbps instead of up to 2400!)

| 2019-12-13 | mac80211: fix TID field in monitor mode transmit | Fredrik Olofsson | |
| Fix overwriting of the qos_ctrl.tid field for encrypted frames injected on a monitor interface. While qos_ctrl.tid is not encrypted, it's used as an input into the encryption algorithm so it's protected, and thus cannot be modified after encryption. For injected frames, the encryption may already have been done in userspace, so we cannot change any fields. Before passing the frame to the driver, the qos_ctrl.tid field is updated from skb->priority. Prior to dbd50a851c50 skb->priority was updated in ieee80211_select_queue_80211(), but this function is no longer always called. Update skb->priority in ieee80211_monitor_start_xmit() so that the value is stored, and when later code 'modifies' the TID it really sets it to the same value as before, preserving the encryption.

| 2019-12-12 | ethtool: provide link mode names as a string set | Michal Kubecek | |
| Unlike e.g. netdev features, the ethtool ioctl interface requires link mode table to be in sync between kernel and userspace for userspace to be able to display and set all link modes supported by kernel. The way arbitrary length bitsets are implemented in netlink interface, this will be no longer needed. To allow userspace to access all link modes running kernel supports, add table of ethernet link mode names and make it available as a string set to userspace GET_STRSET requests. Add build time check to make sure names are defined for all modes declared in enum ethtool_link_mode_bit_indices. Once the string set is available, make it also accessible via ioctl.

| 2019-12-12 | rtnetlink: provide permanent hardware address in RTM_NEWLINK | Michal Kubecek | |
| Permanent hardware address of a network device was traditionally provided via ethtool ioctl interface but as Jiri Pirko pointed out in a review of ethtool netlink interface, rtnetlink is much more suitable for it so let's add it to the RTM_NEWLINK message.

| 2019-12-10 | tipc: fix retrans failure due to wrong destination | Tuong Lien | |
| When a user message is sent, TIPC will check if the socket has faced a congestion at link layer. If that happens, it will make a sleep to wait for the congestion to disappear. This leaves a gap for other users to take over the socket (e.g. multi threads) since the socket is released as well. Also, in case of connectionless (e.g. SOCK_RDM), user is free to send messages to various destinations (e.g. via 'sendto()'), then the socket's preformatted header has to be updated correspondingly prior to the actual payload message building. Unfortunately, the latter action is done before the first action which causes a condition issue that the destination of a certain message can be modified incorrectly in the middle, leading to wrong destination when that message is built. Consequently, when the message is sent to the link layer, it gets stuck there forever because the peer node will simply reject it. After a number of retransmission attempts, the link is eventually taken down and the retransmission failure is reported. This commit fixes the problem by rearranging the order of actions to prevent the race condition from occurring, so the message building is 'atomic' and its header will not be modified by anyone.

| 2019-12-10 | tipc: fix potential hanging after b/rcast changing | Tuong Lien | |
| In commit c55c8edafa91 ("tipc: smooth change between replicast and broadcast"), we allow instant switching between replicast and broadcast by sending a dummy 'SYN' packet on the last used link to synchronize packets on the links. The 'SYN' message is an object of link congestion also, so if that happens, a 'SOCK_WAKEUP' will be scheduled to be sent back to the socket... However, in that commit, we simply use the same socket 'cong_link_cnt' counter for both the 'SYN' & normal payload message sending. Therefore, if both the replicast & broadcast links are congested, the counter will be not updated correctly but overwritten by the latter congestion. Later on, when the 'SOCK_WAKEUP' messages are processed, the counter is reduced one by one and eventually overflowed. Consequently, further activities on the socket will only wait for the false congestion signal to disappear but never been met. Because sending the 'SYN' message is vital for the mechanism, it should be done anyway. This commit fixes the issue by marking the message with an error code e.g. 'TIPC_ERR_NO_PORT', so its sending should not face a link congestion, there is no need to touch the socket 'cong_link_cnt' either. In addition, in the event of any error (e.g. -ENOBUFS), we will purge the entire payload message queue and make a return immediately.

| 2019-12-10 | tipc: fix name table rbtree issues | Tuong Lien | |
| The current rbtree for service ranges in the name table is built based on the 'lower' & 'upper' range values resulting in a flaw in the rbtree searching. Some issues have been observed in case of range overlapping: Case #1: unable to withdraw a name entry: After some name services are bound, all of them are withdrawn by user but one remains in the name table forever. This corrupts the table and that service becomes dummy i.e. no real port. E.g. / {22, 22} / / ---> {10, 50} / \ / \ {10, 30} {20, 60} The node {10, 30} cannot be removed since the rbtree searching stops at the node's ancestor i.e. {10, 50}, so starting from it will never reach the finding node. Case #2: failed to send data in some cases: E.g. Two service ranges: {20, 60}, {10, 50} are bound. The rbtree for this service will be one of the two cases below depending on the order of the bindings: {20, 60} {10, 50} <-- / \ / \ / \ / \ {10, 50} NIL <-- NIL {20, 60} (a) (b) Now, try to send some data to service {30}, there will be two results: (a): Failed, no route to host. (b): Ok. The reason is that the rbtree searching will stop at the pointing node as shown above. Case #3: Same as case #2b above but if the data sending's scope is local and the {10, 50} is published by a peer node, then it will result in 'no route to host' even though the other {20, 60} is for example on the local node which should be able to get the data. The issues are actually due to the way we built the rbtree. This commit fixes it by introducing an additional field to each node - named 'max', which is the largest 'upper' of that node subtree. The 'max' value for each subtrees will be propagated correctly whenever a node is inserted/ removed or the tree is rebalanced by the augmented rbtree callbacks. By this way, we can change the rbtree searching appoarch to solve the issues above. Another benefit from this is that we can now improve the searching for a next range matching e.g. in case of multicast, so get rid of the unneeded looping over all nodes in the tree.

| 2019-12-10 | tcp: Cleanup duplicate initialization of sk->sk_state. | Kuniyuki Iwashima | |
| When a TCP socket is created, sk->sk_state is initialized twice as TCP_CLOSE in sock_init_data() and tcp_init_sock(). The tcp_init_sock() is always called after the sock_init_data(), so it is not necessary to update sk->sk_state in the tcp_init_sock(). Before v2.1.8, the code of the two functions was in the inet_create(). In the patch of v2.1.8, the tcp_v4/v6_init_sock() were added and the code of initialization of sk->state was duplicated.

| 2019-12-10 | tipc: introduce variable window congestion control | Jon Maloy | |
| We introduce a simple variable window congestion control for links. The algorithm is inspired by the Reno algorithm, covering both 'slow start', 'congestion avoidance', and 'fast recovery' modes. - We introduce hard lower and upper window limits per link, still different and configurable per bearer type. - We introduce a 'slow start theshold' variable, initially set to the maximum window size. - We let a link start at the minimum congestion window, i.e. in slow start mode, and then let is grow rapidly (+1 per rceived ACK) until it reaches the slow start threshold and enters congestion avoidance mode. - In congestion avoidance mode we increment the congestion window for each window-size number of acked packets, up to a possible maximum equal to the configured maximum window. - For each non-duplicate NACK received, we drop back to fast recovery mode, by setting the both the slow start threshold to and the congestion window to (current_congestion_window / 2). - If the timeout handler finds that the transmit queue has not moved since the previous timeout, it drops the link back to slow start and forces a probe containing the last sent sequence number to the sent to the peer, so that this can discover the stale situation. This change does in reality have effect only on unicast ethernet transport, as we have seen that there is no room whatsoever for increasing the window max size for the UDP bearer. For now, we also choose to keep the limits for the broadcast link unchanged and equal. This algorithm seems to give a 50-100% throughput improvement for messages larger than MTU.

| 2019-12-10 | tipc: eliminate more unnecessary nacks and retransmissions | Jon Maloy | |
| When we increase the link tranmsit window we often observe the following scenario: 1) A STATE message bypasses a sequence of traffic packets and arrives far ahead of those to the receiver. STATE messages contain a 'peers_nxt_snt' field to indicate which was the last packet sent from the peer. This mechanism is intended as a last resort for the receiver to detect missing packets, e.g., during very low traffic when there is no packet flow to help early loss detection. 3) The receiving link compares the 'peer_nxt_snt' field to its own 'rcv_nxt', finds that there is a gap, and immediately sends a NACK message back to the peer. 4) When this NACKs arrives at the sender, all the requested retransmissions are performed, since it is a first-time request. Just like in the scenario described in the previous commit this leads to many redundant retransmissions, with decreased throughput as a consequence. We fix this by adding two more conditions before we send a NACK in this sitution. First, the deferred queue must be empty, so we cannot assume that the potential packet loss has already been detected by other means. Second, we check the 'peers_snd_nxt' field only in probe/ probe_reply messages, thus turning this into a true mechanism of last resort as it was really meant to be.

| 2019-12-10 | tipc: eliminate gap indicator from ACK messages | Jon Maloy | |
| When we increase the link send window we sometimes observe the following scenario: 1) A packet #N arrives out of order far ahead of a sequence of older packets which are still under way. The packet is added to the deferred queue. 2) The missing packets arrive in sequence, and for each 16th of them an ACK is sent back to the receiver, as it should be. 3) When building those ACK messages, it is checked if there is a gap between the link's 'rcv_nxt' and the first packet in the deferred queue. This is always the case until packet number #N-1 arrives, and a 'gap' indicator is added, effectively turning them into NACK messages. 4) When those NACKs arrive at the sender, all the requested retransmissions are done, since it is a first-time request. This sometimes leads to a huge amount of redundant retransmissions, causing a drop in max throughput. This problem gets worse when we in a later commit introduce variable window congestion control, since it drops the link back to 'fast recovery' much more often than necessary. We now fix this by not sending any 'gap' indicator in regular ACK messages. We already have a mechanism for sending explicit NACKs in place, and this is sufficient to keep up the packet flow.

| 2019-12-09 | net-tcp: Disable TCP ssthresh metrics cache by default | Kevin(Yudong) Yang | |
| This patch introduces a sysctl knob "net.ipv4.tcp_no_ssthresh_metrics_save" that disables TCP ssthresh metrics cache by default. Other parts of TCP metrics cache, e.g. rtt, cwnd, remain unchanged. As modern networks becoming more and more dynamic, TCP metrics cache today often causes more harm than benefits. For example, the same IP address is often shared by different subscribers behind NAT in residential networks. Even if the IP address is not shared by different users, caching the slow-start threshold of a previous short flow using loss-based congestion control (e.g. cubic) often causes the future longer flows of the same network path to exit slow-start prematurely with abysmal throughput. Caching ssthresh is very risky and can lead to terrible performance. Therefore it makes sense to make disabling ssthresh caching by default and opt-in for specific networks by the administrators. This practice also has worked well for several years of deployment with CUBIC congestion control at Google.
