Add support for dissection of ip tos and ttl and ipv6 traffic-class and hoplimit. Both are dissected into the same struct. Uses similar call to ip dissection function as with tcp, arp and others. Signed-off-by:

Currently loading a cgroup skb eBPF program require a CAP_SYS_ADMIN capability while attaching the program to a cgroup only requires the user have CAP_NET_ADMIN privilege. We can escape the capability check when load the program just like socket filter program to make the capability requirement consistent.

This allows cgroup eBPF program to classify packet based on their protocol or other detail information. Currently program need CAP_NET_ADMIN privilege to attach a cgroup eBPF program, and A process with CAP_NET_ADMIN can already see all packets on the system, for example, by creating an iptables rules that causes the packet to be passed to userspace via NFLOG.

Currently when a data packet is retransmitted, we do not compute an RTT sample for congestion control due to Kern's check. Therefore the congestion control that uses RTT signals may not receive any update during loss recovery which could last many round trips. For example, BBR and Vegas may not be able to update its min RTT estimation if the network path has shortened until it recovers from losses. This patch mitigates that by using TCP timestamp options for RTT measurement for congestion control. Note that we already use timestamps for RTT estimation. Signed-off-by:

Set initialization state variable to (reflect interrupt initialization) at correct time (immediately after having configured interrupts). This fixes problem of inconsistent IRQ allocation in case of [obscure] failure when negotiating with PF driver during init. Clean-up of interrupt enablement during initialization & avoid potential race condition with chip-specific code (i.e. perform interrupt control in main driver module). Added explanatory comments regarding interrupt enablement. Signed-off-by:

Xin Long authored
Since last patch, sctp doesn't need to alloc memory for asoc->stream any more. sctp_stream_new and sctp_stream_init both are used to alloc memory for stream.in or stream.out, and their names are also confusing. This patch is to merge them into sctp_stream_init, and only pass stream and streamcnt parameters into it, instead of the whole asoc. Signed-off-by:

As Marcelo's suggestion, stream is a fixed size member of asoc and would not grow with more streams. To avoid an allocation for it, this patch is to define it as an object instead of pointer and update the places using it, also create sctp_stream_update() called in sctp_assoc_update() to migrate the stream info from one stream to another.

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-06-01 This series contains updates to i40e, i40evf and the "new" AVF virtchnl. This is the introduction of the Intel(R) Ethernet Adaptive Virtual Function driver code and device ID, as presented at the NetDEV 1.2 conference in 2016. http://netdevconf.org/1.2/session.html?anjali-singhai The idea is to convert the interface between the i40evf driver and the parent i40e PF driver to be generic, as the i40evf driver should in the future be able to run on top of other Intel PF drivers, and negotiate any features beyond a "base expected" set. ==================== Signed-off-by:

Patch #2 adds some information stored on device such as wwpn & wwnn to allow qedf utilize it; #1 fixes an issue with the reading of those values [which were unused until now]. Patch #3 would allow the protocol drivers access to images on persistent storage which is a prerequirement for adding boot from SAN support.

Changes in v3: - drop removal of usused rcv arguments because they will be used later - include the new ksz tagging implementation - add reviewers' tags Changes in v2: - do not remove tagger function copies - document hot path requirements - make netdev_uses_dsa simpler - add reviewers' tags ==================== Signed-off-by: -

As of a86d8bec ("net: dsa: Factor bottom tag receive functions"), the rcv caller frees the original SKB in case or error. Be symmetric with that and make the xmit caller do the same.

This morphs all the i40e and i40evf references to/in virtchnl.h to be generic, using only automated methods. Updates all the callers to use the new names.
