2016-03-29ixgbe: Fix cls_u32 offload support for L4 portsSridhar Samudrala
Fix support for 16 bit source/dest port matches in ixgbe model. u32 uses a single 32-bit key value for both source and destination ports starting at offset 0. So replace the 2 functions with a single function that takes this key value/mask to program both source and dest ports. Verified with the following filter: #tc qdisc add dev p4p1 ingress #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \ handle 1: u32 divisor 1 #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \ handle 800:0:10 u32 ht 800: link 1: \ offset at 0 mask 0f00 shift 6 plus 0 eat match ip protocol 6 ff #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \ handle 1:0:10 u32 ht 1: \ match tcp src 1024 ffff match tcp dst 80 ffff action drop #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \ handle 1:0:11 u32 ht 1: \ match tcp src 1025 ffff action drop #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \ handle 1:0:12 u32 ht 1: \ match tcp dst 81 ffff action drop Signed-off-by: Sridhar Samudrala <sridhar.samudrala@intel.com> Acked-by: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2016-03-29ixgbevf: call ndo_stop() instead of dev_close() when running offline selftestStefan Assmann
Calling dev_close() causes IFF_UP to be cleared which will remove the interfaces routes and some addresses. That's probably not what the user intended when running the offline selftest. Besides this does not happen if the interface is brought down before the test, so the current behaviour is inconsistent. Instead call the net_device_ops ndo_stop function directly and avoid touching IFF_UP at all.

2016-03-29ixgbe: Fix ATR so that it correctly handles IPv6 extension headersAlexander Duyck
The ATR code was assuming that it would be able to use tcp_hdr for every TCP frame that came through. However this isn't the case as it is possible for a frame to arrive that is TCP but sent through something like a raw socket. As a result the driver was setting up bad filters in which tcp_hdr was really pointing to the network header so the data was all invalid. In order to correct this I have added a bit of parsing logic that will determine the TCP header location based off of the network header and either the offset in the case of the IPv4 header, or a walk through the IPv6 extension headers until it encounters the header that indicates IPPROTO_TCP. In addition I have added checks to verify that the lowest protocol provided is recognized as IPv4 or IPv6 to help mitigate raw sockets using ETH_P_ALL from having ATR applied to them.

2016-03-29ixgbe: Store VXLAN port number in network orderAlexander Duyck
The VXLAN port number should be stored in network order instead of in host order as it is accessed from the hot-path in ATR. This way we can avoid having to do any byte swaps in order to validate the port number. I moved the vxlan_port value into a hole in the read-mostly region of the adapter struct. This way it should be in a warm cache-line instead of in some isolated region in memory when it needs to be accessed. In addition I went through and stripped a bunch of unneeded ifdef flags since having an extra variable present doesn't really hurt anything and makes the code easier to read. I also went through and dropped the NETIF_F_RXCSUM flag which was being set in hw_encap_features but provides no value as the flag is not evaluated in the Rx path.

2016-03-29ixgbe: Fix for RAR0 not being set to default MAC addrTushar Dave
commit c9f53e63c208 ("ixgbe: Refactor MAC address configuration code") introduced code that doesn't set HW register RAR0 to default mac address but FF:FF:FF:FF:FF:FF. Due to this, ixgbe HW discards all incoming packets that doesn't have destination mac address equals to FF:FF:FF:FF:FF:FF. This commit sets RAR0 correctly to default HW mac address.

samples In 473398a21d28 ("perf tools: Add cpumode to struct perf_sample"), I missed some places where perf_sample fields are directly initialized in addition to what is done in perf_evsel__parse_sample(), namely when synthesizing PERF_RECORD_{MMAP*,COMM,FORK,EXIT} for pre-existing threads and also in intel_pt and intel_bts when synthesizing events from processor trace, the jitdump code also was affected, fix it.

These two functions are used by various exception handling functions, only some of which ensure that interrupts or preemption is disabled. However the following have interrupts explicitly enabled or not explicitly disabled: - do_reserved() (irqs enabled) - do_ade() (irqs not disabled) This can be hit by setting /sys/kernel/debug/mips/unaligned_action to 2, and triggering an address error exception, e.g. an unaligned access or access to kernel segment from user mode. To fix the above cases, use raw_smp_processor_id() instead. It is unusual for CPU names to be different in the same system, and even if they were, its possible the process has migrated between the exception of interest and the cpu_name_string() call anyway.

2016-03-29pcmcia: db1xxx_ss: fix last irq_to_gpio userManuel Lauss
remove the usage of removed irq_to_gpio() function. On pre-DB1200 boards, pass the actual carddetect GPIO number instead of the IRQ, because we need the gpio to actually test card status (inserted or not) and can get the irq number with gpio_to_irq() instead. Tested on DB1300 and DB1500, this patch fixes PCMCIA on the DB1500, which used irq_to_gpio().
