When port function state change is requested, and when the driver does not support it, it refers to the hw address attribute instead of state attribute. Seems like a copy paste error. Fix it by referring to the port function state attribute. Fixes: c0bea69d ("devlink: Validate port function request") Signed-off-by:

The original idea of the delay_time check was to not apply multicast snooping too early when an MLD querier appears. And to instead wait at least for MLD reports to arrive before switching from flooding to group based, MLD snooped forwarding, to avoid temporary packet loss. However in a batman-adv mesh network it was noticed that after 248 days of uptime 32bit MIPS based devices would start to signal that they had stopped applying multicast snooping due to missing queriers - even though they were the elected querier and still sending MLD queries themselves. While time_is_before_jiffies() generally is safe against jiffies wrap-arounds, like the code comments in jiffies.h explain, it won't be able to track a difference larger than ULONG_MAX/2. With a 32bit large jiffies and one jiffies tick every 10ms (CONFIG_HZ=100) on these MIPS devices running OpenWrt this would result in a difference larger than ULONG_MAX/2 after 248 (= 2^32/100/60/60/24/2) days and time_is_before_jiffies() would then start to return false instead of true. Leading to multicast snooping not being applied to multicast packets anymore. Fix this issue by using a proper timer_list object which won't have this ULONG_MAX/2 difference limitation. Fixes: b00589af ("bridge: disable snooping if there is no querier") Signed-off-by:

One of the test cases in the test_bridge_backup_port.sh selftest relies on a matchall classifier to drop unrelated traffic so that the Tx drop counter on the VXLAN device will only be incremented as a result of traffic generated by the test. However, the configuration option for the matchall classifier is missing from the configuration file which might explain the failures we see in the netdev CI [1]. Fix by adding CONFIG_NET_CLS_MATCHALL to the configuration file.

syzbot reported an interesting trace [1] caused by a stale sk->sk_wq pointer in a closed llc socket. In commit ff7b11aa ("net: socket: set sock->sk to NULL after calling proto_ops::release()") Eric Biggers hinted that some protocols are missing a sock_orphan(), we need to perform a full audit. In net-next, I plan to clear sock->sk from sock_orphan() and amend Eric patch to add a warning.

With the dma conf being reallocated on each call to stmmac_open(), any information in there is lost, unless we specifically handle it. The STMMAC_TBS_EN bit is set when adding an etf qdisc, and the etf qdisc therefore would stop working when link was set down and then back up.

On a parisc64 kernel I sometimes notice this kernel warning: Kernel unaligned access to 0x40ff8814 at ndisc_send_skb+0xc0/0x4d8 The address 0x40ff8814 points to the in6addr_linklocal_allrouters variable and the warning simply means that some ipv6 function tries to read a 64-bit word directly from the not-64-bit aligned in6addr_linklocal_allrouters variable. Unaligned accesses are non-critical as the architecture or exception handlers usually will fix it up at runtime. Nevertheless it may trigger a performance penality for some architectures. For details read the "unaligned-memory-access" kernel documentation. The patch below ensures that the ipv6 loopback and router addresses will always be naturally aligned. This prevents the unaligned accesses for all architectures. Signed-off-by:

When working with GPIO, its direction must be set either when the GPIO is requested by gpiod_get*() or later on by one of the gpiod_direction_*() functions. Neither of this is done here which results in undefined behavior on some systems. As the reset GPIO is used right after it is requested here, it makes sense to configure it as GPIOD_OUT_HIGH right away. With that, the following gpiod_set_value_cansleep(1) becomes redundant and can be safely removed. Fixes: a653f2f5 ("net: dsa: qca8k: introduce reset via gpio feature") Signed-off-by:

TCP rx zerocopy intent is to map pages initially allocated from NIC drivers, not pages owned by a fs. This patch adds to can_map_frag() these additional checks: - Page must not be a compound one. - page->mapping must be NULL.

rx_data_reassembly skb is stored during NCI data exchange for processing fragmented packets. It is dropped only when the last fragment is processed or when an NTF packet with NCI_OP_RF_DEACTIVATE_NTF opcode is received. However, the NCI device may be deallocated before that which leads to skb leak. As by design the rx_data_reassembly skb is bound to the NCI device and nothing prevents the device to be freed before the skb is processed in some way and cleaned, free it on the NCI device cleanup.

Syzkaller reported [1] hitting a warning after failing to allocate resources for skb in hsr_init_skb(). Since a WARN_ONCE() call will not help much in this case, it might be prudent to switch to netdev_warn_once(). At the very least it will suppress syzkaller reports such as [1]. Just in case, use netdev_warn_once() in send_prp_supervision_frame() for similar reasons.

The logic to determine if SMC-D link group matches is incorrect. The correct logic should be that it only returns true when the GID is the same, and the SMC-D device is the same and the extended GID is the same (in the case of virtual ISM). It can be fixed by adding brackets around the conditional (or ternary) operator expression. But for better readability and maintainability, it has been changed to an if-else statement. Reported-by:

Louis Peens says: ==================== nfp: flower: a few small conntrack offload fixes This small series addresses two bugs in the nfp conntrack offloading code. The first patch is a check to prevent offloading for a case which is currently not supported by the nfp. The second patch fixes up parsing of layer4 mangling code so it can be correctly offloaded. Since the masks are an inverse mask and we are shifting it so it can be packed together with the destination we effectively need to 'clear' the lower bits of the mask by setting it to 0xFFFF. ==================== Link: https://lore.kernel.org/r/20240124151909.31603-1-louis.peens@corigine.comSigned-off-by:

The nfp driver will merge the tp source port and tp destination port into one dword which the offset must be zero to do hardware offload. However, the mangle action for the tp source port and tp destination port is separated for tc ct action. Modify the mangle action for the FLOW_ACT_MANGLE_HDR_TYPE_TCP and FLOW_ACT_MANGLE_HDR_TYPE_UDP to satisfy the nfp driver offload check for the tp port. The mangle action provides a 4B value for source, and a 4B value for the destination, but only 2B of each contains the useful information. For offload the 2B of each is combined into a single 4B word. Since the incoming mask for the source is '0xFFFF<mask>' the shift-left will throw away the 0xFFFF part. When this gets combined together in the offload it will clear the destination field. Fix this by setting the lower bits back to 0xFFFF, effectively doing a rotate-left operation on the mask.

The nfp offload flow pay will not allocate a mask id when the out port is openvswitch internal port. This is because these flows are used to configure the pre_tun table and are never actually send to the firmware as an add-flow message. When a tc rule which action contains ct and the post ct entry's out port is openvswitch internal port, the merge offload flow pay with the wrong mask id of 0 will be send to the firmware. Actually, the nfp can not support hardware offload for this situation, so return EOPNOTSUPP.

Arguably is more a refactor than a fix, but still targeting net to hopefully The second patch fixes the integration of such tests with the build system.

The blamed commit below introduce a dependency in some net self-tests towards a newly introduce helper script. Such script is currently not included into the TEST_PROGS_EXTENDED list and thus is not installed, causing failure for the relevant tests when executed from the install dir. Fix the issue updating the install targets. Fixes: 3bdd9fd2 ("selftests/net: synchronize udpgro tests' tx and rx connection") Signed-off-by:

Several net tests requires an XDP program build under the ebpf directory, and error out if such program is not available. That makes running successful net test hard, let's duplicate into the net dir the [very small] program, re-using the existing rules to build it, and finally dropping the bogus dependency.

Still a bit unclear whether each directory should have its own config file, but assuming they should lets add one for tcp_ao. The following tests still fail with this config in place: - rst_ipv4, - rst_ipv6, - bench-lookups_ipv6. other 21 pass. Fixes: d11301f6 ("selftests/net: Add TCP-AO ICMPs accept test") Reviewed-by:
