Prior to commit fa538f7c ("netfilter: nf_reject: add reject skbuff creation helpers"), nft_reject_bridge did not assign to nskb->dev before passing nskb on to br_forward(). The shared skbuff creation helpers introduced in above commit do which seems to confuse br_forward() as reject statements in prerouting hook won't emit a packet anymore. Fix this by simply passing NULL instead of 'dev' to the helpers - they use the pointer for just that assignment, nothing else.

Most flexcan IP cores support 2 RX modes: - FIFO - mailbox The flexcan IP core on the MCF5441X cannot receive CAN RTR messages via mailboxes. However the mailbox mode is more performant. The commit | 1c45f577 ("can: flexcan: add ethtool support to change rx-rtr setting during runtime") added support to switch from FIFO to mailbox mode on these cores. After testing the mailbox mode on the MCF5441X by Angelo Dureghello, this patch marks it (without RTR capability) as supported. Further the IP core overview table is updated, that RTR reception via mailboxes is not supported. Link: https://lore.kernel.org/all/20220121084425.3141218-1-mkl@pengutronix.deTested-by:

In order to optimize FIFO access, especially on m_can cores attached to slow busses like SPI, in patch | e3938177 ("can: m_can: Disable IRQs on FIFO bus errors") bulk read/write support has been added to the m_can_fifo_{read,write} functions. That change leads to the tcan driver to call regmap_bulk_{read,write}() with a length of 0 (for CAN frames with 0 data length). regmap treats this as an error: | tcan4x5x spi1.0 tcan4x5x0: FIFO write returned -22 This patch fixes the problem by not calling the cdev->ops->{read,write)_fifo() in case of a 0 length read/write.

When 'ping' changes to use PING socket instead of RAW socket by: # sysctl -w net.ipv4.ping_group_range="0 100" the selftests 'router_broadcast.sh' will fail, as such command # ip vrf exec vrf-h1 ping -I veth0 198.51.100.255 -b can't receive the response skb by the PING socket.

ibmvnic_tasklet() continuously spins waiting for responses to all capability requests. It does this to avoid encountering an error during initialization of the vnic. However if there is a bug in the VIOS and we do not receive a response to one or more queries the tasklet ends up spinning continuously leading to hard lock ups. If we fail to receive a message from the VIOS it is reasonable to timeout the login attempt rather than spin indefinitely in the tasklet.

We use ->running_cap_crqs to determine when the ibmvnic_tasklet() should send out the next protocol message type. i.e when we get back responses to all our QUERY_CAPABILITY CRQs we send out REQUEST_CAPABILITY crqs. Similiary, when we get responses to all the REQUEST_CAPABILITY crqs, we send out the QUERY_IP_OFFLOAD CRQ. We currently increment ->running_cap_crqs as we send out each CRQ and have the ibmvnic_tasklet() send out the next message type, when this running_cap_crqs count drops to 0. This assumes that all the CRQs of the current type were sent out before the count drops to 0. However it is possible that we send out say 6 CRQs, get preempted and receive all the 6 responses before we send out the remaining CRQs. This can result in ->running_cap_crqs count dropping to zero before all messages of the current type were sent and we end up sending the next protocol message too early. Instead initialize the ->running_cap_crqs upfront so the tasklet will only send the next protocol message after all responses are received. Use the cap_reqs local variable to also detect any discrepancy (either now or in future) in the number of capability requests we actually send. Currently only send_query_cap() is affected by this behavior (of sending next message early) since it is called from the worker thread (during reset) and from application thread (during ->ndo_open()) and they can be preempted. send_request_cap() is only called from the tasklet which processes CRQ responses sequentially, is not be affected. But to maintain the existing symmtery with send_query_capability() we update send_request_capability() also.

If auto-priority-failover (APF) is enabled and there are at least two backing devices of different priorities, some resets like fail-over, change-param etc can cause at least two back to back failovers. (Failover from high priority backing device to lower priority one and then back to the higher priority one if that is still functional). Depending on the timimg of the two failovers it is possible to trigger a "hard" reset and for the hard reset to fail due to failovers. When this occurs, the driver assumes that the network is unstable and disables the VNIC for a 60-second "settling time". This in turn can cause the ethtool command to fail with "No such device" while the vnic automatically recovers a little while later. Given that it's possible to have two back to back failures, allow for extra failures before disabling the vnic for the settling time.

During IP fragmentation we sanitize IP options. This means overwriting options which should not be copied with NOPs. Only the first fragment has the original, full options. ip_fraglist_prepare() copies the IP header and options from previous fragment to the next one. Commit 19c3401a ("net: ipv4: place control buffer handling away from fragmentation iterators") moved sanitizing options before ip_fraglist_prepare() which means options are sanitized and then overwritten again with the old values. Fixing this is not enough, however, nor did the sanitization work prior to aforementioned commit. ip_options_fragment() (which does the sanitization) uses ipcb->opt.optlen for the length of the options. ipcb->opt of fragments is not populated (it's 0), only the head skb has the state properly built. So even when called at the right time ip_options_fragment() does nothing. This seems to date back all the way to v2.5.44 when the fast path for pre-fragmented skbs had been introduced. Prior to that ip_options_build() would have been called for every fragment (in fact ever since v2.5.44 the fragmentation handing in ip_options_build() has been dead code, I'll clean it up in -next). In the original patch (see Link) caixf mentions fixing the handling for fragments other than the second one, but I'm not sure how _any_ fragment could have had their options sanitized with the code as it stood. Tested with python (MTU on lo lowered to 1000 to force fragmentation): import socket s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) s.setsockopt(socket.IPPROTO_IP, socket.IP_OPTIONS, bytearray([7,4,5,192, 20|0x80,4,1,0])) s.sendto(b'1'*2000, ('127.0.0.1', 1234)) Before: IP (tos 0x0, ttl 64, id 1053, offset 0, flags [+], proto UDP (17), length 996, options (RR [bad length 4] [bad ptr 5] 192.148.4.1,,RA value 256)) localhost.36500 > localhost.search-agent: UDP, length 2000 IP (tos 0x0, ttl 64, id 1053, offset 968, flags [+], proto UDP (17), length 996, options (RR [bad length 4] [bad ptr 5] 192.148.4.1,,RA value 256)) localhost > localhost: udp IP (tos 0x0, ttl 64, id 1053, offset 1936, flags [none], proto UDP (17), length 100, options (RR [bad length 4] [bad ptr 5] 192.148.4.1,,RA value 256)) localhost > localhost: udp After: IP (tos 0x0, ttl 96, id 42549, offset 0, flags [+], proto UDP (17), length 996, options (RR [bad length 4] [bad ptr 5] 192.148.4.1,,RA value 256)) localhost.51607 > localhost.search-agent: UDP, bad length 2000 > 960 IP (tos 0x0, ttl 96, id 42549, offset 968, flags [+], proto UDP (17), length 996, options (NOP,NOP,NOP,NOP,RA value 256)) localhost > localhost: udp IP (tos 0x0, ttl 96, id 42549, offset 1936, flags [none], proto UDP (17), length 100, options (NOP,NOP,NOP,NOP,RA value 256)) localhost > localhost: udp RA (20 | 0x80) is now copied as expected, RR (7) is "NOPed out".

Improve retransmission backoff by only backing off when we retransmit data packets rather than when we set the lost ack timer. To this end: (1) In rxrpc_resend(), use rxrpc_get_rto_backoff() when setting the retransmission timer and only tell it that we are retransmitting if we actually have things to retransmit. Note that it's possible for the retransmission algorithm to race with the processing of a received ACK, so we may see no packets needing retransmission. (2) In rxrpc_send_data_packet(), don't bump the backoff when setting the ack_lost_at timer, as it may then get bumped twice. With this, when looking at one particular packet, the retransmission intervals were seen to be 1.5ms, 2ms, 3ms, 5ms, 9ms, 17ms, 33ms, 71ms, 136ms, 264ms, 544ms, 1.088s, 2.1s, 4.2s and 8.3s.

Subbaraya Sundeep says: ==================== octeontx-af2: Fixes for CN10K and CN9xxx platforms This patchset has consolidated fixes in Octeontx2 driver handling CN10K and CN9xxx platforms. When testing the new CN10K hardware some issues resurfaced like accessing wrong register for CN10K and enabling loopback on not supported interfaces. Some fixes are needed for CN9xxx platforms as well. Below is the description of patches Patch 1: AF sets RX RSS action for all the VFs when a VF is brought up. But when a PF sets RX action for its VF like Drop/Direct to a queue in ntuple filter it is not retained because of AF fixup. This patch skips modifying VF RX RSS action if PF has already set its action. Patch 2: When configuring backpressure wrong register is being read for LBKs hence fixed it. Patch 3: Some RVU blocks may take longer time to reset but are guaranteed to complete the reset. Hence wait till reset is complete. Patch 4: For enabling LMAC CN10K needs another register compared to CN9xxx platforms. Hence changed it. Patch 5: Adds missing barrier before submitting memory pointer to the aura hardware. Patch 6: Increase polling time while link credit restore and also return proper error code when timeout occurs. Patch 7: Internal loopback not supported on LPCS interfaces like SGMII/QSGMII so do not enable it. Patch 8: When there is a error in message processing, AF sets the error response and replies back to requestor. PF forwards a invalid message to VF back if AF reply has error in it. This way VF lacks the actual error set by AF for its message. This is changed such that PF simply forwards the actual reply and let VF handle the error. Patch 9: ntuple filter with "flow-type ether proto 0x8842 vlan 0x92e" was not working since ethertype 0x8842 is NGIO protocol. Hardware parser explicitly parses such NGIO packets and sets the packet as NGIO and do not set it as tagged packet. Fix this by changing parser such that it sets the packet as both NGIO and tagged by using separate layer types. ==================== Signed-off-by: -
