The sctp_sf_eat_auth() function is supposed to return enum sctp_disposition values but if the call to sctp_ulpevent_make_authkey() fails, it returns -ENOMEM. This results in calling BUG() inside the sctp_side_effects() function. Calling BUG() is an over reaction and not helpful. Call WARN_ON_ONCE() instead. This code predates git. Signed-off-by:

The commit 59a0b022 ("ipvlan: Make skb->skb_iif track skb->dev for l3s mode") fixed ipvlan bonded dev checking by updating skb skb_iif. This fix works for IPv4, as in raw_v4_input() the dif is from inet_iif(skb), which is skb->skb_iif when there is no route. But for IPv6, the fix is not enough, because in ipv6_raw_deliver() -> raw_v6_match(), the dif is inet6_iif(skb), which is returns IP6CB(skb)->iif instead of skb->skb_iif if it's not a l3_slave. To fix the IPv6 part issue. Let's set IP6CB(skb)->iif to correct ifindex. BTW, ipvlan handles NS/NA specifically. Since it works fine, I will not reset IP6CB(skb)->iif when addr->atype is IPVL_ICMPV6.

In the last step of the EEH recovery process, the EEH driver calls into bnx2x_io_resume() to re-initialize the NIC hardware via the function bnx2x_nic_load(). If an error occurs during bnx2x_nic_load(), OS and hardware resources are released and an error code is returned to the caller. When called from bnx2x_io_resume(), the return code is ignored and the network interface is brought up unconditionally. Later attempts to send a packet via this interface result in a page fault due to a null pointer reference. This patch checks the return code of bnx2x_nic_load(), prints an error message if necessary, and does not enable the interface. Signed-off-by:

Also, if the PF allocates more than 32 IRQs, this mask will prevent us from using all of them.

Matthieu Baerts says: ==================== selftests: mptcp: skip tests not supported by old kernels (part 2) After a few years of increasing test coverage in the MPTCP selftests, we realised [1] the last version of the selftests is supposed to run on old kernels without issues. Supporting older versions is not that easy for this MPTCP case: these selftests are often validating the internals by checking packets that are exchanged, when some MIB counters are incremented after some actions, how connections are getting opened and closed in some cases, etc. In other words, it is not limited to the socket interface between the userspace and the kernelspace. In addition to that, the current MPTCP selftests run a lot of different sub-tests but the TAP13 protocol used in the selftests don't support sub-tests: one failure in sub-tests implies that the whole selftest is seen as failed at the end because sub-tests are not tracked. It is then important to skip sub-tests not supported by old kernels. To minimise the modifications and reduce the complexity to support old versions, the idea is to look at external signs and skip the whole selftests or just some sub-tests before starting them. This cannot be applied in all cases. This second part focuses on marking different sub-tests as skipped if some MPTCP features are not supported. A few techniques are used here: - Before starting some tests: - Check if a file (sysctl knob) is present: that's what patch 13/14 is doing for the userspace PM feature. - Check if a symbol is present in /proc/kallsyms: patch 1/14 adds some helpers in mptcp_lib.sh to ease its use. Then these helpers are used in patches 2, 3, 4, 10, 11 and 14/14. - Set a flag and get the status to check if a feature is supported: patch 8/14 is doing that with the 'fullmesh' flag. - After having launched the tests: - Retrieve the counters after a test and check if they are different than 0. Similar to the check with the flag, that's not ideal but in this case, the counters were already present before the introduction of MPTCP but they have been supported by MPTCP sockets only later. Patches 5 and 6/14 are using this technique. Before skipping tests, SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES env var value is checked: if it is set to 1, the test is marked as "failed" instead of "skipped". MPTCP public CI expects to have all features supported and it sets this env var to 1 to catch regressions in these new checks. Patches 7/14 and 9/14 are a bit different because they don't skip tests: - Patch 7/14 retrieves the default values instead of using hardcoded ones because these default values have been modified at some points. Then the comparisons are done with the default values. - patch 9/14 relaxes the expected returned size from MPTCP's getsockopt because the different structures gathering various info can get new fields and get bigger over time. We cannot expect that the userspace is using the same structure as the kernel. Patch 12/14 marks the test as "skipped" instead of "failed" if the "ip" tool is not available. In this second part, the "mptcp_join" selftest is not modified yet. This will come soon after in the third part with quite a few patches.

The userspace can also expect a smaller size if it is compiled with old uAPI kernel headers. So for these sizes, we can only check if they are above a certain threshold, 0 for the moment. We can also only compared sizes with the ones set by the kernel.

In the event of a failure in tcf_change_indev(), u32_set_parms() will immediately return without decrementing the recently incremented reference counter. If this happens enough times, the counter will rollover and the reference freed, leading to a double free which can be used to do 'bad things'. In order to prevent this, move the point of possible failure above the point where the reference counter is incremented. Also save any meaningful return values to be applied to the return data at the appropriate point in time. This issue was caught with KASAN.

As shown in [1], out-of-bounds access occurs in two cases: 1)when the qdisc of the taprio type is used to replace the previously configured taprio, count and offset in tc_to_txq can be set to 0. In this case, the value of *txq in taprio_next_tc_txq() will increases continuously. When the number of accessed queues exceeds the number of queues on the device, out-of-bounds access occurs. 2)When packets are dequeued, taprio can be deleted. In this case, the tc rule of dev is cleared. The count and offset values are also set to 0. In this case, out-of-bounds access is also caused. Now the restriction on the queue number is added.

Instead of relying on skb->transport_header being set correctly, opt instead to parse the L3 header length out of the L3 headers for both IPv4/IPv6 when the Extended Layer Op for tcp/udp is used. This fixes a bug if GRO is disabled, when GRO is disabled skb->transport_header is set by __netif_receive_skb_core() to point to the L3 header, it's later fixed by the upper protocol layers, but act_pedit will receive the SKB before the fixups are completed.

82580/i354/i350 features circle-counter-like timestamp registers that are different with newer i210. The EXTTS capture value in AUXTSMPx should be converted from raw circle counter value to timestamp value in resolution of 1 nanosec by the driver. This issue can be reproduced on i350 nics, connecting an 1PPS signal to a SDP pin, and run 'ts2phc' command to read external 1PPS timestamp value. On i210 this works fine, but on i350 the extts is not correctly converted. The i350/i354/82580's SYSTIM and other timestamp registers are 40bit counters, presenting time range of 2^40 ns, that means these registers overflows every about 1099s. This causes all these regs can't be used directly in contrast to the newer i210/i211s. The igb driver needs to convert these raw register values to valid time stamp format by using kernel timecounter apis for i350s families. Here the igb_extts() just forgot to do the convert.

Ping sockets can't send packets when they're bound to a VRF master device and the output interface is set to a slave device. For example, when net.ipv4.ping_group_range is properly set, so that ping6 can use ping sockets, the following kind of commands fails: $ ip vrf exec red ping6 fe80::854:e7ff:fe88:4bf1%eth1 What happens is that sk->sk_bound_dev_if is set to the VRF master device, but 'oif' is set to the real output device. Since both are set but different, ping_v6_sendmsg() sees their value as inconsistent and fails. Fix this by allowing 'oif' to be a slave device of ->sk_bound_dev_if. This fixes the following kselftest failure: $ ./fcnal-test.sh -t ipv6_ping [...] TEST: ping out, vrf device+address bind - ns-B IPv6 LLA [FAIL] Reported-by:

For ENETC hardware, the TCs are numbered from 0 to N-1, where N is the number of TCs. Numerically higher TC has higher priority. It's obvious that the highest priority TC index should be N-1 and the 2nd highest priority TC index should be N-2. However, the previous logic uses netdev_get_prio_tc_map() to get the indexes of highest priority and 2nd highest priority TCs, it does not make sense and is incorrect to give a "tc" argument to netdev_get_prio_tc_map(). So the driver may get the wrong indexes of the two highest priotiry TCs which would lead to failed to set the CBS for the two highest priotiry TCs. e.g. $ tc qdisc add dev eno0 parent root handle 100: mqprio num_tc 6 \ map 0 0 1 1 2 3 4 5 queues 1@0 1@1 1@2 1@3 2@4 2@6 hw 1 $ tc qdisc replace dev eno0 parent 100:6 cbs idleslope 100000 \ sendslope -900000 hicredit 12 locredit -113 offload 1 $ Error: Specified device failed to setup cbs hardware offload. ^^^^^ In this example, the previous logic deems the indexes of the two highest priotiry TCs should be 3 and 2. Actually, the indexes are 5 and 4, because the number of TCs is 6. So it would be failed to configure the CBS for the two highest priority TCs.

In case of error when adding a new rule that refers to an anonymous set, deactivate expressions via NFT_TRANS_PREPARE state, not NFT_TRANS_RELEASE. Thus, the lookup expression marks anonymous sets as inactive in the next generation to ensure it is not reachable in this transaction anymore and decrement the set refcount as introduced by c1592a89 ("netfilter: nf_tables: deactivate anonymous set from preparation phase"). The abort step takes care of undoing the anonymous set. This is also consistent with rule deletion, where NFT_TRANS_PREPARE is used. Note that this error path is exercised in the preparation step of the commit protocol. This patch replaces nf_tables_rule_release() by the deactivate and destroy calls, this time with NFT_TRANS_PREPARE. Due to this incorrect error handling, it is possible to access a dangling pointer to the anonymous set that remains in the transaction list.
