The stated intent of the original commit is to is to "return the timestamp corresponding to the highest sequence number data returned." The current implementation returns the timestamp for the last byte of the last fully read skb, which is not necessarily the last byte in the recv buffer. This patch converts behavior to the original definition, and to the behavior of the previous draft versions of commit 98aaa913 ("tcp: Extend SOF_TIMESTAMPING_RX_SOFTWARE to TCP recvmsg") which also match this behavior.

syzbot managed to trigger a recursive NETDEV_FEAT_CHANGE event between bonding master and slave. I managed to find a reproducer for this: ip li set bond0 up ifenslave bond0 eth0 brctl addbr br0 ethtool -K eth0 lro off brctl addif br0 bond0 ip li set br0 up When a NETDEV_FEAT_CHANGE event is triggered on a bonding slave, it captures this and calls bond_compute_features() to fixup its master's and other slaves' features. However, when syncing with its lower devices by netdev_sync_lower_features() this event is triggered again on slaves when the LRO feature fails to change, so it goes back and forth recursively until the kernel stack is exhausted. Commit 17b85d29 intentionally lets __netdev_update_features() return -1 for such a failure case, so we have to just rely on the existing check inside netdev_sync_lower_features() and skip NETDEV_FEAT_CHANGE event only for this specific failure case.

When a subflow is created via mptcp_subflow_create_socket(), a new 'struct socket' is allocated, with a new i_ino value. When inspecting TCP sockets via the procfs and or the diag interface, the above ones are not related to the process owning the MPTCP master socket, even if they are a logical part of it ('ss -p' shows an empty process field) Additionally, subflows created by the path manager get the uid/gid from the running workqueue. Subflows are part of the owning MPTCP master socket, let's adjust the vfs info to reflect this. After this patch, 'ss' correctly displays subflows as belonging to the msk socket creator.

This reverts commit 19bda36c: | ipv6: add mtu lock check in __ip6_rt_update_pmtu | | Prior to this patch, ipv6 didn't do mtu lock check in ip6_update_pmtu. | It leaded to that mtu lock doesn't really work when receiving the pkt | of ICMPV6_PKT_TOOBIG. | | This patch is to add mtu lock check in __ip6_rt_update_pmtu just as ipv4 | did in __ip_rt_update_pmtu. The above reasoning is incorrect. IPv6 *requires* icmp based pmtu to work. There's already a comment to this effect elsewhere in the kernel: $ git grep -p -B1 -A3 'RTAX_MTU lock' net/ipv6/route.c=4813= static int rt6_mtu_change_route(struct fib6_info *f6i, void *p_arg) ... /* In IPv6 pmtu discovery is not optional, so that RTAX_MTU lock cannot disable it.

When we fill up a receive VQ, try_fill_recv currently tries to count kicks using a 64 bit stats counter. Turns out, on a 32 bit kernel that uses a seqcount. sequence counts are "lock" constructs where you need to make sure that writers are serialized. In turn, this means that we mustn't run two try_fill_recv concurrently. Which of course we don't. We do run try_fill_recv sometimes from a softirq napi context, and sometimes from a fully preemptible context, but the later always runs with napi disabled. However, when it comes to the seqcount, lockdep is trying to enforce the rule that the same lock isn't accessed from preemptible and softirq context - it doesn't know about napi being enabled/disabled. This causes a false-positive warning: WARNING: inconsistent lock state ... inconsistent {SOFTIRQ-ON-W} -> {IN-SOFTIRQ-W} usage. As a work around, shut down the warning by switching to u64_stats_update_begin_irqsave - that works by disabling interrupts on 32 bit only, is a NOP on 64 bit.

This patch adds FLOW_ACTION_HW_STATS_DONT_CARE which tells the driver that the frontend does not need counters, this hw stats type request never fails. The FLOW_ACTION_HW_STATS_DISABLED type explicitly requests the driver to disable the stats, however, if the driver cannot disable counters, it bails out. TCA_ACT_HW_STATS_* maintains the 1:1 mapping with FLOW_ACTION_HW_STATS_* except by disabled which is mapped to FLOW_ACTION_HW_STATS_DISABLED (this is 0 in tc). Add tc_act_hw_stats() to perform the mapping between TCA_ACT_HW_STATS_* and FLOW_ACTION_HW_STATS_*. Fixes: 319a1d19 ("flow_offload: check for basic action hw stats type") Signed-off-by:

Jason A. Donenfeld says: ==================== wireguard fixes for 5.7-rc5 With Ubuntu and Debian having backported this into their kernels, we're finally seeing testing from places we hadn't seen prior, which is nice. With that comes more fixes: 1) The CI for PPC64 was running with extremely small stacks for 64-bit, causing spurious crashes in surprising places. 2) There's was an old leftover routing loop restriction, which no longer makes sense given the queueing architecture, and was causing problems for people who really did want nested routing. 3) Not yielding our kthread on CONFIG_PREEMPT_VOLUNTARY systems caused RCU stalls and other issues, reported by Wang Jian, with the fix suggested by Sultan Alsawaf. 4) Clang spewed warnings in a selftest for CONFIG_IPV6=n, reported by Arnd Bergmann. 5) A complicated if statement was simplified to an assignment while also making the likely/unlikely hinting more correct and simple, and increasing readability, suggested by Sultan. Patches (2) and (3) have Fixes: lines and are probably good candidates for stable. ==================== Signed-off-by: -

It's very unlikely that send will become true. It's nearly always false between 0 and 120 seconds of a session, and in most cases becomes true only between 120 and 121 seconds before becoming false again. So, unlikely(send) is clearly the right option here. What happened before was that we had this complex boolean expression with multiple likely and unlikely clauses nested. Since this is evaluated left-to-right anyway, the whole thing got converted to unlikely. So, we can clean this up to better represent what's going on. The generated code is the same. Suggested-by:

Users with pathological hardware reported CPU stalls on CONFIG_ PREEMPT_VOLUNTARY=y, because the ringbuffers would stay full, meaning these workers would never terminate. That turned out not to be okay on systems without forced preemption, which Sultan observed. This commit adds a cond_resched() to the bottom of each loop iteration, so that these workers don't hog the core. Note that we don't need this on the napi poll worker, since that terminates after its budget is expended. Suggested-by:

Jason A. Donenfeld authored
It's already possible to create two different interfaces and loop packets between them. This has always been possible with tunnels in the kernel, and isn't specific to wireguard. Therefore, the networking stack already needs to deal with that. At the very least, the packet winds up exceeding the MTU and is discarded at that point. So, since this is already something that happens, there's no need to forbid the not very exceptional case of routing a packet back to the same interface; this loop is no different than others, and we shouldn't special case it, but rather rely on generic handling of loops in general. This also makes it easier to do interesting things with wireguard such as onion routing. At the same time, we add a selftest for this, ensuring that both onion routing works and infinite routing loops do not crash the kernel. We also add a test case for wireguard interfaces nesting packets and sending traffic between each other, as well as the loop in this case too. We make sure to send some throughput-heavy traffic for this use case, to stress out any possible recursion issues with the locks around workqueues.

While at some point it might have made sense to be running these tests on ppc64 with 4k stacks, the kernel hasn't actually used 4k stacks on 64-bit powerpc in a long time, and more interesting things that we test don't really work when we deviate from the default (16k). So, we stop pushing our luck in this commit, and return to the default instead of the minimum. Signed-off-by:

The Segment Routing Header (SRH) which defines the SRv6 dataplane is defined in RFC8754. RFC8754 (section 4.1) defines the SR source node behavior which encapsulates packets into an outer IPv6 header and SRH. The SR source node encodes the full list of Segments that defines the packet path in the SRH. Then, the first segment from list of Segments is copied into the Destination address of the outer IPv6 header and the packet is sent to the first hop in its path towards the destination. If the Segment list has only one segment, the SR source node can omit the SRH as he only segment is added in the destination address. RFC8754 (section 4.1.1) defines the Reduced SRH, when a source does not require the entire SID list to be preserved in the SRH. A reduced SRH does not contain the first segment of the related SR Policy (the first segment is the one already in the DA of the IPv6 header), and the Last Entry field is set to n-2, where n is the number of elements in the SR Policy. RFC8754 (section 4.3.1.1) defines the SRH processing and the logic to validate the SRH (S09, S10, S11) which works for both reduced and non-reduced behaviors. This patch updates seg6_validate_srh() to validate the SRH as per RFC8754. Signed-off-by:

It looks like the sja1105 external timestamping input is not as generic as we thought. When fed a signal with 50% duty cycle, it will timestamp both the rising and the falling edge. When fed a short pulse signal, only the timestamp of the falling edge will be seen in the PTPSYNCTS register, because that of the rising edge had been overwritten. So the moral is: don't feed it short pulse inputs. Luckily this is not a complete deal breaker, as we can still work with 1 Hz square waves. But the problem is that the extts polling period was not dimensioned enough for this input signal. If we leave the period at half a second, we risk losing timestamps due to jitter in the measuring process. So we need to increase it to 4 times per second. Also, the very least we can do to inform the user is to deny any other flags combination than with PTP_RISING_EDGE and PTP_FALLING_EDGE both set.
