We already get child qdisc qlen, we also can get its backlog so that class dumps can report it. Also replace qstats by a single drop counter, but move it in a separate cache line so that drops do not dirty useful cache lines.

Now we defer skb drops, it makes sense to keep a copy of skb->truesize in struct codel_skb_cb to avoid one cache line miss per dropped skb in fq_codel_drop(), to reduce latencies a bit further. Signed-off-by: NEric Dumazet <edumazet@google.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Qdisc performance suffers when packets are dropped at enqueue() time because drops (kfree_skb()) are done while qdisc lock is held, delaying a dequeue() draining the queue. Nominal throughput can be reduced by 50 % when this happens, at a time we would like the dequeue() to proceed as fast as possible. Even FQ is vulnerable to this problem, while one of FQ goals was to provide some flow isolation. This patch adds a 'struct sk_buff **to_free' parameter to all qdisc->enqueue(), and in qdisc_drop() helper. I measured a performance increase of up to 12 %, but this patch is a prereq so that future batches in enqueue() can fly.

由 Hariprasad Shenai 提交于
The issue comes when there are multiple threads attempting to use the mailbox facility at the same time. The issue is the for the Virtual Function Driver, the only way to get the Virtual Interface statistics is to issue mailbox commands to ask the firmware for the VI Stats. And, because the VI Stats command can only retrieve a smallish number of stats per mailbox command, we have to issue three mailbox commands in quick succession. When ethtool or netstat command to get interface stats and interface up/down is run in a loop for every 0.1 sec, we observed mailbox collisions. And out of the two commands one would fail with the present code, since we don't queue the second command. To overcome the above issue, added a queue to access the mailbox. Whenever a mailbox command is issued add it to the queue. If its at the head issue the mailbox command, else wait for the existing command to complete. Usually command takes less than a milli-second to complete. Also timeout from the loop, if the command under execution takes long time to run. In reality, the number of mailbox access collisions is going to be very rare since no one runs such abusive script. Signed-off-by: NHariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: NDavid S.

Only set conntrack mark or labels when the commit flag is specified. This makes sure we can not set them before the connection has been persisted, as in that case the mark and labels would be lost in an event of an userspace upcall. OVS userspace already requires the commit flag to accept setting ct_mark and/or ct_labels. Validate for this in the kernel API.

Due to a typo we would always be using the MIB counter width of the first element of the counter array instead of the current element, and we would always be accessing the register statistics with a 64-bits read, while some could be 32-bits. This got unnoticed in testing with MDIO and SRAB which tolerate doing this, but testing with the SPI bus revealed bogus values being returned. Fix this by using the proper iterator here.

The commit f2a4d086 ("openvswitch: Add packet truncation support.") introduces packet truncation before sending to userspace upcall receiver. This patch passes up the skb->len before truncation so that the upcall receiver knows the original packet size. Potentially this will be used by sFlow, where OVS translates sFlow config header=N to a sample action, truncating packet to N byte in kernel datapath. Thus, only N bytes instead of full-packet size is copied from kernel to userspace, saving the kernel-to-userspace bandwidth.
