Commit 07d4510f ("dt-bindings: net: bgmac: add bindings documentation for bgmac") added both brcm,amac-nsp.txt and brcm,bgmac-nsp.txt. The former is actually the one that got updated and is in use by the bgmac driver while the latter is duplicating the former and is not used nor updated.

Fixes the following behavior: for connections that had no RTT sample at the time of initializing congestion control, BBR was initializing the pacing rate to a high nominal rate (based an a guess of RTT=1ms, in case this is LAN traffic). Then BBR never adjusted the pacing rate downward upon obtaining an actual RTT sample, if the connection never filled the pipe (e.g. all sends were small app-limited writes()). This fix adjusts the pacing rate upon obtaining the first RTT sample. Fixes: 0f8782ea ("tcp_bbr: add BBR congestion control") Signed-off-by:

Fix a corner case noticed by Eric Dumazet, where BBR's setting sk->sk_pacing_rate to 0 during initialization could theoretically cause packets in the sending host to hang if there were packets "in flight" in the pacing infrastructure at the time the BBR congestion control state is initialized. This could occur if the pacing infrastructure happened to race with bbr_init() in a way such that the pacer read the 0 rather than the immediately following non-zero pacing rate.

Neal Cardwell authored
In bbr_set_pacing_rate(), which decides whether to cut the pacing rate, there was some code that considered exiting STARTUP to be equivalent to the notion of filling the pipe (i.e., bbr_full_bw_reached()). Specifically, as the code was structured, exiting STARTUP and going into PROBE_RTT could cause us to cut the pacing rate down to something silly and low, based on whatever bandwidth samples we've had so far, when it's possible that all of them have been small app-limited bandwidth samples that are not representative of the bandwidth available in the path. (The code was correct at the time it was written, but the state machine changed without this spot being adjusted correspondingly.)

When there is an established connection in direction A->B, it is possible to receive a packet on port B which then executes ct(commit,force) without first performing ct() - ie, a lookup. In this case, we would expect that this packet can delete the existing entry so that we can commit a connection with direction B->A. However, currently we only perform a check in skb_nfct_cached() for whether OVS_CS_F_TRACKED is set and OVS_CS_F_INVALID is not set, ie that a lookup previously occurred. In the above scenario, a lookup has not occurred but we should still be able to statelessly look up the existing entry and potentially delete the entry if it is in the opposite direction. This patch extends the check to also hint that if the action has the force flag set, then we will lookup the existing entry so that the force check at the end of skb_nfct_cached has the ability to delete the connection.

Some time ago David Woodhouse reported skb_under_panic when we try to push ethernet header to fragmented ipv6 skbs. It was fixed for ipv6 by Florian Westphal in commit 1d325d21 ("ipv6: ip6_fragment: fix headroom tests and skb leak") However similar problem still exist in ipv4. It does not trigger skb_under_panic due paranoid check in ip_finish_output2, however according to Alexey Kuznetsov current state is abnormal and ip_fragment should be fixed too. Signed-off-by:

Marcelo noticed an array overflow caused by commit c28445c3 ("sctp: add reconf_enable in asoc ep and netns"), in which sctp would add SCTP_CID_RECONF into extensions when reconf_enable is set in sctp_make_init and sctp_make_init_ack. Then now when all ext chunks are set, 4 ext chunk ids can be put into extensions array while extensions array size is 3. It would cause a kernel panic because of this overflow. This patch is to fix it by defining extensions array size is 4 in both sctp_make_init and sctp_make_init_ack. Fixes: c28445c3 ("sctp: add reconf_enable in asoc ep and netns") Signed-off-by:

One string we pass into the cs->info buffer might be too long, as pointed out by gcc: drivers/isdn/divert/isdn_divert.c: In function 'll_callback': drivers/isdn/divert/isdn_divert.c:488:22: error: '%d' directive writing between 1 and 3 bytes into a region of size between 1 and 69 [-Werror=format-overflow=] sprintf(cs->info, "%d 0x%lx %s %s %s %s 0x%x 0x%x %d %d %s\n", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/isdn/divert/isdn_divert.c:488:22: note: directive argument in the range [0, 255] drivers/isdn/divert/isdn_divert.c:488:4: note: 'sprintf' output 25 or more bytes (assuming 129) into a destination of size 90 This is unlikely to actually cause problems, so let's use snprintf as a simple workaround to shut up the warning and truncate the buffer instead.

If the interface is not up, then don't try to close it during a shutdown. This avoids possible double free of the IRQ, which can happen during a shutdown. Fixes: 03eb3eb4 ("net: qcom/emac: add shutdown function") Signed-off-by:

This change enables the use of SW timestamping on Raspberry PI. smsc95xx uses the usbnet transmit function usbnet_start_xmit(), which implements software timestamping. However the SOF_TIMESTAMPING_TX_SOFTWARE capability was missing and only SOF_TIMESTAMPING_RX_SOFTWARE was announced. By using ethtool_op_get_ts_info() as get_ts_info() also the SOF_TIMESTAMPING_TX_SOFTWARE is announced. Signed-off-by:

When PACKET_QDISC_BYPASS is not used, Tx queue selection will be done before the packet is enqueued, taking into account any mappings set by a queuing discipline such as mqprio without hardware offloading. This selection may be affected by a previously saved queue_mapping, either on the Rx path, or done before the packet reaches the device, as it's currently the case for AF_PACKET. In order for queue selection to work as expected when using traffic control, there can't be another selection done before that point is reached, so move the call to packet_pick_tx_queue to packet_direct_xmit, leaving the default xmit path as it was before PACKET_QDISC_BYPASS was introduced. A forward declaration of packet_pick_tx_queue() is introduced to avoid the need to reorder the functions within the file.

With 802.1ad support the vlan_ingress code started checking for vlan protocol mismatch which causes the current tag to be inserted and the bridge vlan protocol & pvid to be set. The vlan tag insertion changes the skb mac_header and thus the lookup mac dest pointer which was loaded prior to calling br_allowed_ingress in br_handle_frame_finish is VLAN_HLEN bytes off now, pointing to the last two bytes of the destination mac and the first four of the source mac causing lookups to always fail and broadcasting all such packets to all ports. Same thing happens for locally originated packets when passing via br_dev_xmit. So load the dest pointer after the vlan checks and possible skb change.
