Pass the already obtained vlan group pointer to br_mst_vlan_set_state() instead of dereferencing it again. Each caller has already correctly dereferenced it for their context.

The net.ipv6.route.flush system parameter takes a value which specifies a delay used during the flush operation for aging exception routes. The written value is however not used in the currently requested flush and instead utilized only in the next one. A problem is that ipv6_sysctl_rtcache_flush() first reads the old value of net->ipv6.sysctl.flush_delay into a local delay variable and then calls proc_dointvec() which actually updates the sysctl based on the provided input. Fix the problem by switching the order of the two operations. Fixes: 4990509f ("[NETNS][IPV6]: Make sysctls route per namespace.") Signed-off-by:

The current cbs parameter depends on speed after uplinking, which is not needed and will report a configuration error if the port is not initially connected. The UAPI exposed by tc-cbs requires userspace to recalculate the send slope anyway, because the formula depends on port_transmit_rate (see man tc-cbs), which is not an invariant from tc's perspective. Therefore, we use offload->sendslope and offload->idleslope to derive the original port_transmit_rate from the CBS formula. Fixes: 1f705bc6 ("net: stmmac: Add support for CBS QDISC") Signed-off-by:

TSO currently fails when the skb's gso_type field has more than one bit set. TSO packets can be passed from userspace using PF_PACKET, TUNTAP and a few others, using virtio_net_hdr (e.g., PACKET_VNET_HDR). This includes virtualization, such as QEMU, a real use-case. The gso_type and gso_size fields as passed from userspace in virtio_net_hdr are not trusted blindly by the kernel. It adds gso_type |= SKB_GSO_DODGY to force the packet to enter the software GSO stack for verification. This issue might similarly come up when the CWR bit is set in the TCP header for congestion control, causing the SKB_GSO_TCP_ECN gso_type bit to be set.

Lion Ackermann reported that there is a race condition between namespace cleanup in ipset and the garbage collection of the list:set type. The namespace cleanup can destroy the list:set type of sets while the gc of the set type is waiting to run in rcu cleanup. The latter uses data from the destroyed set which thus leads use after free. The patch contains the following parts: - When destroying all sets, first remove the garbage collectors, then wait if needed and then destroy the sets. - Fix the badly ordered "wait then remove gc" for the destroy a single set case. - Fix the missing rcu locking in the list:set type in the userspace test case. - Use proper RCU list handlings in the list:set type. The patch depends on c1193d9b (netfilter: ipset: Add list flush to cancel_gc). Fixes: 97f7cf1c (netfilter: ipset: fix performance regression in swap operation) Reported-by:

Due to timer wheel implementation, a timer will usually fire after its schedule. For instance, for HZ=1000, a timeout between 512ms and 4s has a granularity of 64ms. For this range of values, the extra delay could be up to 63ms. For TCP, this means that tp->rcv_tstamp may be after inet_csk(sk)->icsk_timeout whenever the timer interrupt finally triggers, if one packet came during the extra delay. We need to make sure tcp_rtx_probe0_timed_out() handles this case. Fixes: e89688e3 ("net: tcp: fix unexcepted socket die when snd_wnd is 0") Signed-off-by:

The creation of new subflows can fail for different reasons. If no subflow have been created using the received ADD_ADDR, the related counters should not be updated, otherwise they will never be decremented for events related to this ID later on. For the moment, the number of accepted ADD_ADDR is only decremented upon the reception of a related RM_ADDR, and only if the remote address ID is currently being used by at least one subflow. In other words, if no subflow can be created with the received address, the counter will not be decremented. In this case, it is then important not to increment pm.add_addr_accepted counter, and not to modify pm.accept_addr bit. Note that this patch does not modify the behaviour in case of failures later on, e.g. if the MP Join is dropped or rejected. The "remove invalid addresses" MP Join subtest has been modified to validate this case. The broadcast IP address is added before the "valid" address that will be used to successfully create a subflow, and the limit is decreased by one: without this patch, it was not possible to create the last subflow, because: - the broadcast address would have been accepted even if it was not usable: the creation of a subflow to this address results in an error, - the limit of 2 accepted ADD_ADDR would have then been reached.

The RmAddr MIB counter is supposed to be incremented once when a valid RM_ADDR has been received. Before this patch, it could have been incremented as many times as the number of subflows connected to the linked address ID, so it could have been 0, 1 or more than 1. The "RmSubflow" is incremented after a local operation. In this case, it is normal to tied it with the number of subflows that have been actually removed. The "remove invalid addresses" MP Join subtest has been modified to validate this case. A broadcast IP address is now used instead: the client will not be able to create a subflow to this address. The consequence is that when receiving the RM_ADDR with the ID attached to this broadcast IP address, no subflow linked to this ID will be found.

This is strictly related to commit fb7a0d33 ("mptcp: ensure snd_nxt is properly initialized on connect"). It turns out that syzkaller can trigger the retransmit after fallback and before processing any other incoming packet - so that snd_una is still left uninitialized.

When the noop_qdisc owner isn't initialized, then it will be 0, so packets will erroneously be regarded as having been subject to recursion as long as only CPU 0 queues them. For non-SMP, that's all packets, of course. This causes a change in what's reported to userspace, normally noop_qdisc would drop packets silently, but with this change the syscall returns -ENOBUFS if RECVERR is also set on the socket. Fix this by initializing the owner field to -1, just like it would be for dynamically allocated qdiscs by qdisc_alloc().

Commit 070246e4 ("net: stmmac: Fix for mismatched host/device DMA address width") added support in the stmmac driver for platform drivers to indicate the host DMA width, but left it up to authors of the specific platforms to indicate if their width differed from the addr64 register read from the MAC itself. Qualcomm's EMAC4 integration supports only up to 36 bit width (as opposed to the addr64 register indicating 40 bit width). Let's indicate that in the platform driver to avoid a scenario where the driver will allocate descriptors of size that is supported by the CPU which in our case is 36 bit, but as the addr64 register is still capable of 40 bits the device will use two descriptors as one address.

In lio_vf_rep_copy_packet() pg_info->page is compared to a NULL value, but then it is unconditionally passed to skb_add_rx_frag() which looks strange and could lead to null pointer dereference. lio_vf_rep_copy_packet() call trace looks like: octeon_droq_process_packets octeon_droq_fast_process_packets octeon_droq_dispatch_pkt octeon_create_recv_info ...search in the dispatch_list... ->disp_fn(rdisp->rinfo, ...) lio_vf_rep_pkt_recv(struct octeon_recv_info *recv_info, ...) In this path there is no code which sets pg_info->page to NULL. So this check looks unneeded and doesn't solve potential problem. But I guess the author had reason to add a check and I have no such card and can't do real test. In addition, the code in the function liquidio_push_packet() in liquidio/lio_core.c does exactly the same. Based on this, I consider the most acceptable compromise solution to adjust this issue by moving skb_add_rx_frag() into conditional scope.

Matthieu Baerts says: ==================== selftests: net: lib: small fixes While looking at using 'lib.sh' for the MPTCP selftests [1], we found some small issues with 'lib.sh'. Here they are: - Patch 1: fix 'errexit' (set -e) support with busywait. 'errexit' is supported in some functions, not all. A fix for v6.8+. - Patch 2: avoid confusing error messages linked to the cleaning part when the netns setup fails. A fix for v6.8+. - Patch 3: set a variable as local to avoid accidentally changing the value of a another one with the same name on the caller side. A fix for v6.10-rc1+.

Without this, the 'i' variable declared before could be overridden by accident, e.g. for i in "${@}"; do __ksft_status_merge "${i}" ## 'i' has been modified foo "${i}" ## using 'i' with an unexpected value done After a quick look, it looks like 'i' is currently not used after having been modified in __ksft_status_merge(), but still, better be safe than sorry. I saw this while modifying the same file, not because I suspected an issue somewhere.

If there is an error to create the first netns with 'setup_ns()', 'cleanup_ns()' will be called with an empty string as first parameter. The consequences is that 'cleanup_ns()' will try to delete an invalid netns, and wait 20 seconds if the netns list is empty. Instead of just checking if the name is not empty, convert the string separated by spaces to an array. Manipulating the array is cleaner, and calling 'cleanup_ns()' with an empty array will be a no-op. Fixes: 25ae948b ("selftests/net: add lib.sh") Cc: stable@vger.kernel.org Acked-by:

If errexit is enabled ('set -e'), loopy_wait -- or busywait and others using it -- will stop after the first failure. Note that if the returned status of loopy_wait is checked, and even if errexit is enabled, Bash will not stop at the first error.
