* Merge branch 'ipv6-auto-flow-labels'David S. Miller2015-07-319-33/+151
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tom Herbert says: ==================== ipv6: Turn on auto IPv6 flow labels by default BSD (MacOS) has already turned on flow labels by default and this does not seem to be causing any problems in the Internet. Let's go ahead and turn them on by default. We'll continue to monitor for any devices start choking on them. Flow labels are important since they are the desired solution for network devices to perform ECMP and RSS (RFC6437 and RFC6438). Traditionally, devices perform a 5-tuple hash on packets that includes port numbers. For the most part, these devices can only compute 5-tuple hashes for TCP and UDP. This severely limits our ability to get good network load balancing for other protocols (IPIP, GRE,ESP, etc.), and hence we are limited in using other protocols. Unfortunately, this method is accepted as the de facto standard to the extent that there are several proposals to encapsulate protocols in UDP _just_ for the purposes for getting ECMP to work. With hosts generating flow labels and devices taking them as input into ECMP (several already do), we can start to fix this fundamental problem. This patch set: - Changes IPV6_FLOWINFO sockopt to be opt-out of flow labels for connections rather than opt-in - Disable flow label state ranges sysctl by default - Enable auto flow labels sysctl by default v2: - Added functions to create an skb->hash based on flowi4 and flowi6. These are called in output path when creating a packet - Call skb_get_hash_flowi6 in ip6_make_flowlabel - Implement the auto_flowlabels sysctl as a mode for auto flowlabels. There are four modes which correspond to flow labels being enabled and whether socket option can be used to opt in or opt out of using them ==================== Signed-off-by: David S.

| * ipv6: Enable auto flow labels by defaultTom Herbert2015-07-312-2/+2
| | | | | | | | | | | | | | | | | | Initialize auto_flowlabels to one. This enables automatic flow labels, individual socket may disable them using the IPV6_AUTOFLOWLABEL socket option. Signed-off-by: Tom Herbert <tom@herbertland.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * ipv6: Disable flowlabel state ranges by defaultTom Herbert2015-07-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Per RFC6437 stateful flow labels (e.g. labels set by flow label manager) cannot "disturb" nodes taking part in stateless flow labels. While the ranges only reduce the flow label entropy by one bit, it is conceivable that this might bias the algorithm on some routers causing a load imbalance. For best results on the Internet we really need the full 20 bits. Signed-off-by: Tom Herbert <tom@herbertland.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * ipv6: Implement different admin modes for automatic flow labelsTom Herbert2015-07-316-25/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the meaning of net.ipv6.auto_flowlabels to provide a mode for automatic flow labels generation. There are four modes: 0: flow labels are disabled 1: flow labels are enabled, sockets can opt-out 2: flow labels are allowed, sockets can opt-in 3: flow labels are enabled and enforced, no opt-out for sockets np->autoflowlabel is initialized according to the sysctl value.

These functions can be called when creating a packet in the output path where the new sk_buff does not yet contain a fully formed packet that is parsable by flow dissector.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Florian Fainelli says: ==================== net: GENET, SYSTEMPORT and DSA netconsole This patch series adds support for netconsole in the GENET, SYSTEMPORT and DSA drivers. A small refactoring to the DSA transmit path is required to avoid duplicating the dsa_netpoll_send_skb() into each and every tagging protocol supported. Testing on e.g: mv643xx_eth and/or e1000e would be much appreciated! Changes in v2: - properly disable/enable interrupts in GENET and SYSTEMPORT - pass the reallocated SKB back to dsa_slave_xmit() in case a tag protocol had to alter the original SKB ==================== Signed-off-by: David S.

| * net: dsa: Add netconsole supportFlorian Fainelli2015-07-312-0/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | Add support for using DSA slave network devices with netconsole, which requires us to allocate and free custom netpoll instances and invoke the parent network device poll controller callback. In order for netconsole to work, we need to construct the DSA tag, but not queue the skb for transmission on the master network device xmit function.

| * net: dsa: Refactor transmit path to eliminate duplicationFlorian Fainelli2015-07-316-49/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All tagging protocols do the same thing: increment device statistics, make room for the tag to be inserted, create the tag, invoke the parent network device transmit function. In order to prepare for adding netpoll support, which requires the tag creation, but not using the parent network device transmit function, do some little refactoring which eliminates duplication between the 4 tagging protocols supported. We need to return a sk_buff pointer back to the caller because the tag specific transmit function may have to reallocate the original skb (e.g: tag_trailer.c) and this is the one we should be transmitting, not the original sk_buff we were passed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Broadcom's firmware requires every BSS to use MAC address with unique last few bits. The amount of bits may depend on a particular firmware, it was verified to be 2 for BCM43602 one. If this condition won't be fulfilled firmware will reject such MAC: brcmfmac: _brcmf_set_mac_address: Setting cur_etheraddr failed, -52 We don't want to simply set addr_mask as it would also disallow using locally administrated bit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A long time ago, ath9k had issues during reset where the DMA engine would stay active and could potentially corrupt memory. To debug those issues, the driver would print warnings whenever they occur. Nowadays, these issues are gone and the primary cause of these messages is if the MAC is stuck during reset or busy processing a long transmission. This is fairly harmless, yet these messages continue to worry users. To reduce the number of bogus bug reports, turn these messages into debug messages and count their occurence in the "reset" debugfs file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mwifiex_set_wowlan_mef_entry attempts to free a passed-in pointer in case of an error. The only caller (mwifiex_set_mef_filter) passes that pointer as an offset into allocated memory, so any attempt to free that will not be the actual allocated pointer. Address this by changing mwifiex_set_wowlan_mef_entry to not do any free, and to cause mwifiex_set_mef_filter to do the appropriate free if the call to mwifiex_set_wowlan_mef_entry fails.

| | | | | | | | | | | | | | | | | | | | | | It was observed that AP beacons would not reflect correct regulatory information upon starting AP in A band. This was because of missing AP config band update in set_channel of start_ap. Also we configure 11D settings info FW only for specific band. So we need to download domain info to FW even if domain remains unchanged but band is changed. Signed-off-by: Avinash Patil <patila@marvell.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
