So far changing the period by just setting new period values while running did not work. The order as indicated by the publicly available reference manual of the i.MX8MP [1] indicates a sequence: * initiate the programming sequence * set the values for PPS period and start time * start the pulse train generation. This is currently not used in dwmac5_flex_pps_config(), which instead does: * initiate the programming sequence and immediately start the pulse train generation * set the values for PPS period and start time This caused the period values written not to take effect until the FlexPPS output was disabled and re-enabled again. This patch fix the order and allows the period to be set immediately. [1] https://www.nxp.com/webapp/Download?colCode=IMX8MPRM Fixes: 9a8a02c9 ("net: stmmac: Add Flexible PPS support") Signed-off-by:

There was a problem reported to us where the addition of a VF with an IPv6 address ending with a particular sequence would cause the parent device on the PF to no longer be able to respond to neighbor discovery packets. In this case, we had an ovs-bridge device living on top of a VLAN, which was on top of a PF, and it would not be able to talk anymore (the neighbor entry would expire and couldn't be restored). The root cause of the issue is that if the PF is asked to be in IFF_PROMISC mode (promiscuous mode) and it had an ipv6 address that needed the 33:33:ff:00:00:04 multicast address to work, then when the VF was added with the need for the same multicast address, the VF would steal all the traffic destined for that address. The ice driver didn't auto-subscribe a request of IFF_PROMISC to the "multicast replication from other port's traffic" meaning that it won't get for instance, packets with an exact destination in the VF, as above. The VF's IPv6 address, which adds a "perfect filter" for 33:33:ff:00:00:04, results in no packets for that multicast address making it to the PF (which is in promisc but NOT "multicast replication"). The fix is to enable "multicast promiscuous" whenever the driver is asked to enable IFF_PROMISC, and make sure to disable it when appropriate.

Currently checks for weight and priority ranges don't check incoming value from the devlink. Instead it checks node current weight or priority. This makes those checks useless.

In bnxt_reserve_rings(), there is logic to check that the number of TX rings reserved is enough to cover all the mqprio TCs, but it fails to account for the TX XDP rings. So the check will always fail if there are mqprio TCs and TX XDP rings. As a result, the driver always fails to initialize after the XDP program is attached and the device will be brought down. A subsequent ifconfig up will also fail because the number of TX rings is set to an inconsistent number. Fix the check to properly account for TX XDP rings. If the check fails, set the number of TX rings back to a consistent number after calling netdev_reset_tc(). Fixes: 674f50a5 ("bnxt_en: Implement new method to reserve rings.") Reviewed-by:

When converting net_device_stats to rtnl_link_stats64 sign extension is triggered on ILP32 machines as 6c1c5097 changed the previous "ulong -> u64" conversion to "long -> u64" by accessing the net_device_stats fields through a (signed) atomic_long_t. This causes for example the received bytes counter to jump to 16EiB after having received 2^31 bytes. Casting the atomic value to "unsigned long" beforehand converting it into u64 avoids this.

syzbot reported that act_len in kalmia_send_init_packet() is uninitialized when passing it to the first usb_bulk_msg error path. Jiri Pirko noted that it's pointless to pass it in the error path, and that the value that would be printed in the second error path would be the value of act_len from the first call to usb_bulk_msg.[1] With this in mind, let's just not pass act_len to the usb_bulk_msg error paths. 1: https://lore.kernel.org/lkml/Y9pY61y1nwTuzMOa@nanopsycho/ Fixes: d4026123 ("net/usb: Add Samsung Kalmia driver for Samsung GT-B3730") Reported-and-tested-by: syzbot+cd80c5ef5121bfe85b55@syzkaller.appspotmail.com Signed-off-by:

Christoph Paasch reported that commit b5fc2923 ("inet6: Remove inet6_destroy_sock() in sk->sk_prot->destroy().") started triggering WARN_ON_ONCE(sk->sk_forward_alloc) in sk_stream_kill_queues(). [0 - 2] Also, we can reproduce it by a program in [3]. In the commit, we delay freeing ipv6_pinfo.pktoptions from sk->destroy() to sk->sk_destruct(), so sk->sk_forward_alloc is no longer zero in inet_csk_destroy_sock().

Eric Dumazet pointed out [0] that when we call skb_set_owner_r() for ipv6_pinfo.pktoptions, sk_rmem_schedule() has not been called, resulting in a negative sk_forward_alloc. We add a new helper which clones a skb and sets its owner only when sk_rmem_schedule() succeeds. Note that we move skb_set_owner_r() forward in (dccp|tcp)_v6_do_rcv() because tcp_send_synack() can make sk_forward_alloc negative before ipv6_opt_accepted() in the crossed SYN-ACK or self-connect() cases.

In TI's AM62x/AM64x SoCs, successful teardown of RX DMA Channel raises an interrupt. The process of servicing this interrupt involves flushing all pending RX DMA descriptors and clearing the teardown completion marker (TDCM). The am65_cpsw_nuss_rx_packets() function invoked from the RX NAPI callback services the interrupt. Thus, it is necessary to wait for this handler to run, drain all packets and clear TDCM, before calling napi_disable() in am65_cpsw_nuss_common_stop() function post channel teardown. If napi_disable() executes before ensuring that TDCM is cleared, the TDCM remains set when the interfaces are down, resulting in an interrupt storm when the interfaces are brought up again. Since the interrupt raised to indicate the RX DMA Channel teardown is specific to the AM62x and AM64x SoCs, add a quirk for it.

Commit b3973bb4 ("vmxnet3: set correct hash type based on rss information") added hashType information into skb. However, rssType field is populated for eop descriptor. This can lead to incorrectly reporting of hashType for packets which use multiple rx descriptors. Multiple rx descriptors are used for Jumbo frame or LRO packets, which can hit this issue. This patch moves the RSS codeblock under eop descritor. Cc: stable@vger.kernel.org Fixes: b3973bb4 ("vmxnet3: set correct hash type based on rss information") Signed-off-by:

Furthermore, when I disable back PTP RX timestamping (ptp4l doesn't do that when it exists), packets are RX filtered again as they should be: ~/selftests/drivers/net/dsa# hwstamp_ctl -i swp0 -r 0 [ 218.202854] mscc_felix 0000:00:00.5: ocelot_l2_ptp_trap_del: port 0 removing L2 PTP trap [ 218.212656] mscc_felix 0000:00:00.5: ocelot_ipv4_ptp_trap_del: port 0 removing IPv4 PTP event trap [ 218.222975] mscc_felix 0000:00:00.5: ocelot_ipv4_ptp_trap_del: port 0 removing IPv4 PTP general trap [ 218.233133] mscc_felix 0000:00:00.5: ocelot_ipv6_ptp_trap_del: port 0 removing IPv6 PTP event trap [ 218.242251] mscc_felix 0000:00:00.5: ocelot_ipv6_ptp_trap_del: port 0 removing IPv6 PTP general trap current settings: tx_type 1 rx_filter 12 new settings: tx_type 1 rx_filter 0 ~/selftests/drivers/net/dsa# ./local_termination.sh eno0 swp0 TEST: swp0: Unicast IPv4 to primary MAC address [ OK ] TEST: swp0: Unicast IPv4 to macvlan MAC address [ OK ] TEST: swp0: Unicast IPv4 to unknown MAC address [ OK ] TEST: swp0: Unicast IPv4 to unknown MAC address, promisc [ OK ] TEST: swp0: Unicast IPv4 to unknown MAC address, allmulti [ OK ] TEST: swp0: Multicast IPv4 to joined group [ OK ] TEST: swp0: Multicast IPv4 to unknown group [ OK ] TEST: swp0: Multicast IPv4 to unknown group, promisc [ OK ] TEST: swp0: Multicast IPv4 to unknown group, allmulti [ OK ] TEST: swp0: Multicast IPv6 to joined group [ OK ] TEST: swp0: Multicast IPv6 to unknown group [ OK ] TEST: swp0: Multicast IPv6 to unknown group, promisc [ OK ] TEST: swp0: Multicast IPv6 to unknown group, allmulti [ OK ] So it's clear that something in the PTP RX trapping logic went wrong. Looking a bit at the code, I can see that there are 4 typos, which populate "ipv4" VCAP IS2 key filter fields for IPv6 keys. VCAP IS2 keys of type OCELOT_VCAP_KEY_IPV4 and OCELOT_VCAP_KEY_IPV6 are handled by is2_entry_set(). OCELOT_VCAP_KEY_IPV4 looks at &filter->key.ipv4, and OCELOT_VCAP_KEY_IPV6 at &filter->key.ipv6. Simply put, when we populate the wrong key field, &filter->key.ipv6 fields "proto.mask" and "proto.value" remain all zeroes (or "don't care"). So is2_entry_set() will enter the "else" of this "if" condition: if (msk == 0xff && (val == IPPROTO_TCP || val == IPPROTO_UDP)) and proceed to ignore the "proto" field. The resulting rule will match on all IPv6 traffic, trapping it to the CPU. This is the reason why the local_termination.sh selftest sees it, because control traps are stronger than the PGID_MCIPV6 used for flooding (from the forwarding data path). But the problem is in fact much deeper. We trap all IPv6 traffic to the CPU, but if we're bridged, we set skb->offload_fwd_mark = 1, so software forwarding will not take place and IPv6 traffic will never reach its destination. The fix is simple - correct the typos. I was intentionally inaccurate in the commit message about the breakage occurring when any PTP timestamping is enabled. In fact it only happens when L4 timestamping is requested (HWTSTAMP_FILTER_PTP_V2_EVENT or HWTSTAMP_FILTER_PTP_V2_L4_EVENT). But ptp4l requests a larger RX timestamping filter than it needs for "-2": HWTSTAMP_FILTER_PTP_V2_EVENT. I wanted people skimming through git logs to not think that the bug doesn't affect them because they only use ptp4l in L2 mode.
