2017-04-05bnxt_en: Cap the msix vector with the max completion rings.Michael Chan
The current code enables up to the maximum MSIX vectors in the PCIE config space without considering the max completion rings available. An MSIX vector is only useful when it has an associated completion ring, so it is better to cap it. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

2017-04-04net: ethernet: ti: cpsw: fix race condition during open()Sekhar Nori
TI's cpsw driver handles both OF and non-OF case for phy connect. Unfortunately of_phy_connect() returns NULL on error while phy_connect() returns ERR_PTR(). To handle this, cpsw_slave_open() overrides the return value from phy_connect() to make it NULL or error. This leaves a small window, where cpsw_adjust_link() may be invoked for a slave while slave->phy pointer is temporarily set to -ENODEV (or some other error) before it is finally set to NULL. _cpsw_adjust_link() only handles the NULL case, and an oops results when ERR_PTR() is seen by it. Note that cpsw_adjust_link() checks PHY status for each slave whenever it is invoked. It can so happen that even though phy_connect() for a given slave returns error, _cpsw_adjust_link() is still called for that slave because the link status of another slave changed. Fix this by using a temporary pointer to store return value of {of_}phy_connect() and do a one-time write to slave->phy.

Given that pppol2tp_seq_session_show() dereferences the associated PPPoL2TP socket and that l2tp_dfs_seq_session_show() might call pppol2tp_show(), we also need to call the session's .ref() callback to prevent the socket from going away from under us.

Patch #2, #3 fix Timers related ILT configurations that are yet to affect qed in existing scenarios. Patch #4 reduces needless ILT lines wasted for RoCE configurations.

Add support for the net stats64 counters to the usbnet core. With that in place put the hooks into every usbnet driver to use it. This is a strait forward addition of 64bit counters for RX and TX packet and byte counts. It is done in the same style as for the other net drivers that support stats64. Note that the other stats fields remain as 32bit sized values (error counts, etc). The motivation to add this is that it is not particularly difficult to get the RX and TX byte counts to wrap on 32bit platforms.

2017-04-03vxlan: fix ND proxy when skb doesn't have transport header offsetVincent Bernat
When an incoming frame is tagged or when GRO is disabled, the skb handled to vxlan_xmit() doesn't contain a valid transport header offset. This makes ND proxying fail. We combine two changes: replace use of skb_transport_offset() and ensure the necessary amount of skb is linear just before using it: - In vxlan_xmit(), when determining if we have an ICMPv6 neighbor discovery packet, just check if it is an ICMPv6 packet and rely on neigh_reduce() to do more checks if this is the case. The use of pskb_may_pull() is replaced by skb_header_pointer() for just the IPv6 header. - In neigh_reduce(), add pskb_may_pull() for IPv6 header and neighbor discovery message since this was removed from vxlan_xmit(). Replace skb_transport_header() with ipv6_hdr() + 1. - In vxlan_na_create(), replace first skb_transport_offset() with ipv6_hdr() + 1 and second with skb_network_offset() + sizeof(struct ipv6hdr). Additionally, ensure we pskb_may_pull() the whole skb as we need it to iterate over the options. Signed-off-by: Vincent Bernat <vincent@bernat.im> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-04-03tcp: minimize false-positives on TCP/GRO checkMarcelo Ricardo Leitner
Markus Trippelsdorf reported that after commit dcb17d22e1c2 ("tcp: warn on bogus MSS and try to amend it") the kernel started logging the warning for a NIC driver that doesn't even support GRO. It was diagnosed that it was possibly caused on connections that were using TCP Timestamps but some packets lacked the Timestamps option. As we reduce rcv_mss when timestamps are used, the lack of them would cause the packets to be bigger than expected, although this is a valid case. As this warning is more as a hint, getting a clean-cut on the threshold is probably not worth the execution time spent on it. This patch thus alleviates the false-positives with 2 quick checks: by accounting for the entire TCP option space and also checking against the interface MTU if it's available. These changes, specially the MTU one, might mask some real positives, though if they are really happening, it's possible that sooner or later it will be triggered anyway.

2017-04-03sctp: check for dst and pathmtu update in sctp_packet_configXin Long
This patch is to move sctp_transport_dst_check into sctp_packet_config from sctp_packet_transmit and add pathmtu check in sctp_packet_config. With this fix, sctp can update dst or pathmtu before appending chunks, which can void dropping packets in sctp_packet_transmit when dst is obsolete or dst's mtu is changed. This patch is also to improve some other codes in sctp_packet_config. It updates packet max_size with gso_max_size, checks for dst and pathmtu, and appends ecne chunk only when packet is empty and asoc is not NULL. It makes sctp flush work better, as we only need to set up them once for one flush schedule. It's also safe, since asoc is NULL only when the packet is created by sctp_ootb_pkt_new in which it just gets the new dst, no need to do more things for it other than set packet with transport's pathmtu.

There is a bug on Hip06 that tx ring interrupts packets count will be clear when drivers send data to tx ring, so that the tx packets count will never upgrade to packets line, and cause the interrupts engendered was delayed. Sometimes, it will cause sending performance lower than expected. To fix this bug, we set tx ring interrupts packets line to 1 forever, to avoid count clear. And set the gap time to 20us, to solve the problem that too many interrupts engendered when packets line is 1. This patch could advance the send performance on ARM from 6.6G to 9.37G when an iperf send thread on ARM and an iperf send thread on X86 for XGE.
