| | * | | | sched: add and use qdisc_skb_head helpersFlorian Westphal2016-09-19

Its similar to the skb_buff_head api, but does not use skb->prev pointers. Qdiscs will commonly enqueue at the tail of a list and dequeue at head. While skb_buff_head works fine for this, enqueue/dequeue needs to also adjust the prev pointer of next element. The ->prev pointer is not required for qdiscs so we can just leave it undefined and avoid one cacheline write access for en/dequeue.

The only direct caller of the __qdisc_dequeue_head version open-codes this now. This allows us to later use __qdisc_dequeue_head as a replacement of __skb_dequeue() (which operates on sk_buff_head list). Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S.

So we cannot explicitly enable log flags to log uid, tcp sequence, ip options and so on, i.e. such rule "nft add rule filter output log uid" is not supported yet. So move NF_LOG_XXX macro definitions to the uapi/../nf_log.h. In order to keep consistent with other modules, change NF_LOG_MASK to refer to all supported log flags. On the other hand, add a new NF_LOG_DEFAULT_MASK to refer to the original default log flags. Finally, if user specify the unsupported log flags or NFTA_LOG_GROUP and NFTA_LOG_FLAGS are set at the same time, report EINVAL to the userspace.

Followup patch will remove it and rename nf_hook_thresh. The reason is that inet (non-bridge) netfilter no longer invokes the hooks from hooks, so we do no longer need the thresh value to skip hooks with a lower priority. The bridge netfilter however may need to do this. br_nf_hook_thresh is a wrapper that is supposed to do this, i.e. only call hooks with a priority that exceeds NF_BR_PRI_BRNF. It's used only in the recursion cases of br_netfilter. It invokes nf_hook_slow while holding an rcu read-side critical section to make a future cleanup simpler.

This is used by the bridge, netdev and arp families. This new function relies on nft_set_pktinfo_proto_unspec() to set a new tprot_set field that indicates if transport protocol information is available. Remain fields are zeroed. The meta expression has been also updated to check to tprot_set in first place given that zero is a valid tprot value. Even a handcrafted packet may come with the IPPROTO_RAW (255) protocol number so we can't rely on this value as tprot unset.

Since some of the wifi-specific packet handling (notably sequence number and encryption handling) is sensitive to re-ordering, things break if they are applied before the TXQ. This splits up the TX handlers and fast_xmit logic into two parts: An early part and a late part. The former is applied before TXQ enqueue, and the latter after dequeue. The non-TXQ path just applies both parts at once. Because fragments shouldn't be split up or reordered, the fragmentation handler is run after dequeue. Any fragments are then kept in the TXQ and on subsequent dequeues they take precedence over dequeueing from the FQ structure. This approach avoids having to scatter special cases all over the place for when TXQ is enabled, at the cost of making the fast_xmit and TX handler code slightly more complex.

| * | | | | cfg80211: add helper to find an IE that matches a byte-arrayLuca Coelho2016-09-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a few places where an IE that matches not only the EID, but also other bytes inside the element, needs to be found. To simplify that and reduce the amount of similar code, implement a new helper function to match the EID and an extra array of bytes. Additionally, simplify cfg80211_find_vendor_ie() by using the new match function. Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Drivers like ath10k that have its own connection monitoring algorithm, offloaded to firmware for triggering station kickout. In case of station kickout, driver will report low ack status by mac80211 API (ieee80211_report_low_ack). This flag will enable the driver to completely rely on firmware events for station kickout and bypass mac80211 packet loss mechanism.

| * | | | | mac80211: add support for radiotap timestamp fieldJohannes Berg2016-09-12

Currently only 32-bit counters are supported, but we also add the radiotap mactime where applicable. This new field allows more flexibility in where the timestamp is taken etc. The non-timestamp data in the field is taken from a new field in the hw struct.

There exist some devices (latest mobile phones and some AP's) that tend to not respect a BA sessions maximum size (in Kbps). These devices won't respect the AMPDU size that was negotiated during association (even though they do respect the maximal number of packets). This violation is characterized by a valid number of packets in a single AMPDU. Even so, the total size will exceed the size negotiated during association. Eventually, this will cause some undefined behavior, which in turn causes the hw to drop packets, causing the throughput to plummet. This patch will make the subframe limitation to be held by each station, instead of being held only by hw.

Compare this: sudo tc filter add dev $ETH parent 1: protocol ip prio 10 \ u32 match ip protocol 1 0xff flowid 1:2 \ action pedit munge offset -14 u8 set 0x02 \ munge offset -13 u8 set 0x15 \ munge offset -12 u8 set 0x15 \ munge offset -11 u8 set 0x15 \ munge offset -10 u16 set 0x1515 \ pipe to: sudo tc filter add dev $ETH parent 1: protocol ip prio 10 \ u32 match ip protocol 1 0xff flowid 1:2 \ action skbmod dmac 02:15:15:15:15:15 Also try to do a MAC address swap with pedit or worse try to debug a policy with destination mac, source mac and etherype. Then make few rules out of those and you'll get my point. In the future common use cases on pedit can be migrated to this action (as an example different fields in ip v4/6, transports like tcp/udp/sctp etc). For this first cut, this allows modifying basic ethernet header. The most important ethernet use case at the moment is when redirecting or mirroring packets to a remote machine. The dst mac address needs a re-write so that it doesnt get dropped or confuse an interconnecting (learning) switch or dropped by a target machine (which looks at the dst mac). And at times when flipping back the packet a swap of the MAC addresses is needed. Signed-off-by: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by: David S. Miller <davem@davemloft.net>
