2022-05-13mt76: fix tx status related use-after-free race on station removalFelix Fietkau2-1/+3
There is a small race window where ongoing tx activity can lead to a skb getting added to the status tracking idr after that idr has already been cleaned up, which will keep the wcid linked in the status poll list. Fix this by only adding status skbs if the wcid pointer is still assigned in dev->wcid, which gets cleared early by mt76_sta_pre_rcu_remove Fixes: bd1e3e7b693c ("mt76: introduce packet_id idr") Tested-by: Ben Greear <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
2022-05-13mt76: fix encap offload ethernet type checkFelix Fietkau2-2/+6
The driver needs to check if the format is 802.2 vs 802.3 in order to set a tx descriptor flag. skb->protocol can't be used, since it may not be properly initialized for packets coming in from a packet socket. Fix misdetection by checking the ethertype from the skb data instead Reported-by: Thibaut VARÈNE <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
2022-05-13mt76: do not attempt to reorder received 802.3 packets without agg sessionFelix Fietkau1-2/+3

2022-05-13mt76: mt7915: disable RX_HDR_TRANS_SHORTBo Jiao3-4/+6
This patch disables RX_TRANS_SHORT to make MDP to do header translation when payload less than 8 bytes, hence the (QoS) null data can be encapsulated to 802.3 format. However, WDS requires (QoS) null data in 802.11 format to created vlan AP interfaces.

Martin KaFai Lau says: ==================== net: inet: Retire port only listening_hash This series is to retire the port only listening_hash. The listen sk is currently stored in two hash tables, listening_hash (hashed by port) and lhash2 (hashed by port and address). After commit 0ee58dad5b06 ("net: tcp6: prefer listeners bound to an address") and commit d9fbc7f6431f ("net: tcp: prefer listeners bound to an address"), the TCP-SYN lookup fast path does not use listening_hash. The commit 05c0b35709c5 ("tcp: seq_file: Replace listening_hash with lhash2") also moved the seq_file (/proc/net/tcp) iteration usage from listening_hash to lhash2. There are still a few listening_hash usages left. One of them is inet_reuseport_add_sock() which uses the listening_hash to search a listen sk during the listen() system call. This turns out to be very slow on use cases that listen on many different VIPs at a popular port (e.g. 443). [ On top of the slowness in adding to the tail in the IPv6 case ]. A latter patch has a selftest to demonstrate this case.

2022-05-12net: selftests: Stress reuseport listenMartin KaFai Lau3-0/+132
This patch adds a test that has 300 VIPs listening on port 443. Each VIP:443 will have 80 listening socks by using SO_REUSEPORT. Thus, it will have 24000 listening socks. Before removing the port only listening_hash, all socks will be in the same port 443 bucket and inet_reuseport_add_sock() spends much time to walk through the bucket. After removing the port only listening_hash and move all usage to the port+addr lhash2, each bucket in the ideal case has 80 sk which is much smaller than before. Here is the test result from a qemu: Before: listen 24000 socks took 210.210485362 (~210s) After: listen 24000 socks took 0.207173 (~210ms) Signed-off-by: Martin KaFai Lau <[email protected]> Reviewed-by: Eric Dumazet <[email protected]> Signed-off-by: Jakub Kicinski <[email protected]>

The latter patch has a selftest to demonstrate this case. This patch takes this chance to move all remaining listening_hash usages to lhash2 and then retire listening_hash. Since most changes need to be done together, it is hard to cut the listening_hash to lhash2 switch into small patches. The changes in this patch is highlighted here for the review purpose. 1. Because of the listening_hash removal, lhash2 can use the sk->sk_nulls_node instead of the icsk->icsk_listen_portaddr_node. This will also keep the sk_unhashed() check to work as is after stop adding sk to listening_hash. The union is removed from inet_listen_hashbucket because only nulls_head is needed. 2. icsk->icsk_listen_portaddr_node and its helpers are removed. 3. The current lhash2 users needs to iterate with sk_nulls_node instead of icsk_listen_portaddr_node. One case is in the inet[6]_lhash2_lookup(). Another case is the seq_file iterator in tcp_ipv4.c. One thing to note is sk_nulls_next() is needed because the old inet_lhash2_for_each_icsk_continue() does a "next" first before iterating. 4. Move the remaining listening_hash usage to lhash2 inet_reuseport_add_sock() which this series is trying to improve. inet_diag.c and mptcp_diag.c are the final two remaining use cases and is moved to lhash2 now also.

2022-05-12net: inet: Open code inet_hash2 and inet_unhash2Martin KaFai Lau1-55/+33
This patch folds lhash2 related functions into __inet_hash and inet_unhash. This will make the removal of the listening_hash in a latter patch easier to review. First, this patch folds inet_hash2 into __inet_hash. For unhash, the current call sequence is like inet_unhash() => __inet_unhash() => inet_unhash2(). The specific testing cases in __inet_unhash() are mostly related to TCP_LISTEN sk and its caller inet_unhash() already has the TCP_LISTEN test, so this patch folds both __inet_unhash() and inet_unhash2() into inet_unhash(). Note that all listening_hash users also have lhash2 initialized, so the !h->lhash2 check is no longer needed.

It enhances the new sfc-siena.ko module to differentiate it from sfc.ko. Patches Patches 1-5 create separate Kconfig options for Siena, and adjusts the various names used for work items and directories. Patch 6 reinstates SRIOV functionality in sfc-siena.ko. Testing Various build tests were done such as allyesconfig, W=1 and sparse. The new sfc-siena.ko and sfc.ko modules were tested on a machine with NICs for both modules in them.
