* bridge: vlan: enforce no pvid flag in vlan rangesNikolay Aleksandrov2015-10-131-0/+3
| | | | | | | | | | | | | Currently it's possible for someone to send a vlan range to the kernel with the pvid flag set which will result in the pvid bouncing from a vlan to vlan and isn't correct, it also introduces problems for hardware where it doesn't make sense having more than 1 pvid. iproute2 already enforces this, so let's enforce it on kernel-side as well.

* Merge branch 'netns-defrag'David S. Miller2015-10-1311-26/+27
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eric W. Biederman says: ==================== net: Pass net into defragmentation This is the next installment of my work to pass struct net through the output path so the code does not need to guess how to figure out which network namespace it is in, and ultimately routes can have output devices in another network namespace. In netfilter and af_packet we defragment packets in the output path, and there is the usual amount of confusion about how to compute which net we are processing the packets in. This patchset clears that confusion up by explicitly passing in struct net in ip_defrag, ip_check_defrag, and nf_ct_frag6_gather. ==================== Signed-off-by: David S.

| * ipv6: Pass struct net into nf_ct_frag6_gatherEric W. Biederman2015-10-134-6/+5Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function nf_ct_frag6_gather is called on both the input and the output paths of the networking stack. In particular ipv6_defrag which calls nf_ct_frag6_gather is called from both the the PRE_ROUTING chain on input and the LOCAL_OUT chain on output. The addition of a net parameter makes it explicit which network namespace the packets are being reassembled in, and removes the need for nf_ct_frag6_gather to guess. Signed-off-by: "Eric W.

| | | | | | | | | | | | | | | | | | | | | | | | | | The function ip_defrag is called on both the input and the output paths of the networking stack.

|/ | | | | | | | | | | | | | ip_call_ra_chain is called early in the forwarding chain from ip_forward and ip_mr_input, which makes skb->dev the correct expression to get the input network device and dev_net(skb->dev) a correct expression for the network namespace the packet is being processed in.

* packet: fix match_fanout_group()Eric Dumazet2015-10-131-3/+3
| | | | | | | | | | | | | | | | | | Recent TCP listener patches exposed a prior af_packet bug : match_fanout_group() blindly assumes it is always safe to cast sk to a packet socket to compare fanout with af_packet_priv But SYNACK packets can be sent while attached to request_sock, which are smaller than a "struct sock". We can read non existent memory and crash.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the new multi-queue capability depends on a new firmware API, we can already add some code for it.

| | * iwlwifi: mvm: rs: fix success ratio comparison in rs_get_best_rateEyal Shapira2015-10-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | success_ratio is actually 128 * SR in percentage while IWL_MVM_RS_SR_NO_DECREASE is 85%. Fix this by using RS_PERCENT(). This bug caused the if branch to be always executed. This in turn led to always selecting a rate, following a column switch, in which the expected throughput would exceed the best expected current throughput. In some scenarios where the success ratio isn't >85% such a rate could be too aggressive leading us to avoid the new column. This has the potential of causing sub optimal performance.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "DQA" is shorthand for "dynamic queue allocation", with the idea of allocating queues per-RA/TID on-demand rather than using shared queues statically allocated per vif. The goal of this is to enable future features (like GO PM) and to improve performance measurements of TX traffic. When RA/TID streams can't be neatly sorted into different AC queues, DQA allows sharing queues for the same RA. This means that DQA allows different ACs may reach the same HW queue. Update the code to allow such queue sharing by having a mapping between the HW queue and the mac80211 queues using it (as this could be more than one queue).

| | * | ath: use PRI value given by spec for fixed PRIPeter Oh2015-09-273-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PRI value is used as divider when DFS detector analyzes candidate radar pulses. If PRI deviation is big from its origin PRI, DFS detector could miss valid radar reports since HW often misses detecting radar pulses and causes long interval value of pulses. For instance from practical results, if runtime PRI is calculated as 1431 for fixed PRI value of 1428 and delta timestamp logs 15719, the modular remainder will be 1409 and the delta between the remainder and runtime PRI is 22 that is bigger than PRI tolerance which is 16. As a result this radar report will be ignored even though it's valid. By using spec defined PRI for fixed PRI, we can correct this error.

| | * | ath: fix incorrect PPB on JAPAN chirp radarPeter Oh2015-09-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The number of pulses per burst on Japan chirp radar is between 1 and 3. The previous value, 20, is representing number of bursts, but since current DFS detector is using pulse detection other than bursts, use the pulse number for correct radar detection. Also using the highest number helps to avoid false detection. Signed-off-by: Peter Oh <poh@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
