2015-09-01ipvs: Add hdr_flags to iphdrAlex Gartrell
These flags contain information like whether or not the addresses are inverted or from icmp. The first will allow us to drop an inverse param all over the place, and the second will later be useful in scheduling icmp.

RFC 4443 added two new codes values for ICMPv6 type 1: 5 - Source address failed ingress/egress policy 6 - Reject route to destination And RFC 7084 states in L-14 that IPv6 Router MUST send ICMPv6 Destination Unreachable with code 5 for packets forwarded to it that use an address from a prefix that has been invalidated.

Allow setups with large MTU to send large sync packets by adding sync_maxlen parameter. The default value is now based on MTU but no more than 1500 for compatibility reasons.

2015-08-21ipvs: call rtnl_lock earlyJulian Anastasov
When the sync damon is started we need to hold rtnl lock while calling ip_mc_join_group. Currently, we have a wrong locking order because the correct one is rtnl_lock->__ip_vs_mutex. It is implied from the usage of __ip_vs_mutex in ip_vs_dst_event() which is called under rtnl lock during NETDEV_* notifications. Fix the problem by calling rtnl_lock early only for the start_sync_thread call. As a bonus this fixes the usage __dev_get_by_name which was not called under rtnl lock. This patch actually extends and depends on commit 54ff9ef36bdf ("ipv4, ipv6: kill ip_mc_{join, leave}_group and ipv6_sock_mc_{join, drop}").

When changing the number of queues by "ethtool -L", set IGB_FLAG_QUEUE_PAIRS in the same manner as when initializing the igb driver. Vasily Averin provides a fix for a missing rtnl_unlock() for when we error out due to not being able to allocate memory for our queues. Stefan Assman provides a couple of fixes for igb/igbvf. First changes the igb driver in probe to simply call igb_enable_sriov() instead of igb_sriov_reinit() since we are starting from scratch. Then in igbvf, fix the driver where it does not clear the buffer_info->dma in all cases after calling dma_unmap_single(), which was found by changing the MTU twice. Richard Cochran implements the periodic output function using the programmable clock outputs available in i210 when possible, falling back to the target time for longer periods. Todd adds support for the Marvell PHY 1512 which is required for i354 devices. Then updates igb to make sure SR-IOV init uses the correct number of queues, since recent changes could result in the PF holding onto all of the queues. Alex Williamson provides a fix in the case where a guest OS does not support hot-unplug, so disable SR-IOV prior to unregister_netdev() to avoid the problem. Jia-Ju Bai provides several patches, first knocks some collecting dust off an old e100 driver to add a check to avoid a null pointer dereference. Then cleans up a possible resource leak by releasing the skb buffer allocated when the e100_xmit_prepare() runs into an issue in the DMA mapping. In igb, add a missing rtnl_unlock() for when we error out due to igb_sriov_reinit() in the igb_init_interrupt_scheme(). Provides a e1000e fix, based on suggestions from Alex Duyck to move head/tail register writing to e1000_configure_tx/rx() to avoid a possible null pointer dereference (similar to igb driver). Lastly, fix a possible memory leak in igb_probe(), where the memory shadow_vfta allocated by kcalloc in igb_sw_init() is not freed. Mark simplifies port-specific macros for ixgbe by eliminating explicit comparisons with 0 and enclose formal parameters in parens to eliminate the risk of an operator precedence issue. ==================== Signed-off-by: David S.

2015-08-18vrf: simplify the netdev notifier functionNikolay Aleksandrov
We can drop the check because if vrf_ptr is present then we must have the vrf device as a master and since we're running with rtnl it can't go away. Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>

dstats and rth are always present because we fail the device registration if they can't be allocated in vrf_init() (ndo_init) so drop the unnecessary checks. Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-08-18lwtunnel: ip tunnel: fix multiple routes with different encapJiri Benc
Currently, two routes going through the same tunnel interface are considered the same even when they are routed to a different host after encapsulation. This causes all routes added after the first one to have incorrect encapsulation parameters. This is nicely visible by doing: # ip r a 192.168.1.2/32 dev vxlan0 tunnel dst 10.0.0.2 # ip r a 192.168.1.3/32 dev vxlan0 tunnel dst 10.0.0.3 # ip r [...] 192.168.1.2/32 tunnel id 0 src 0.0.0.0 dst 10.0.0.2 [...] 192.168.1.3/32 tunnel id 0 src 0.0.0.0 dst 10.0.0.2 [...] Implement the missing comparison function.

2015-08-18cxgb4: memory corruption in debugfsDan Carpenter
You can't use kstrtoul() with an int or it causes memory corruption. Also j should be unsigned or we have underflow bugs. I considered changing "j" to unsigned long but everything fits in a u32.
