Rahul Lakkireddy says: ==================== cxgb4: add support to offload tc flower This series of patches add support to offload tc flower onto Chelsio NICs. Patch 1 adds basic skeleton to prepare for offloading tc flower flows. Patch 2 adds support to add/remove flows for offload. Flows can have accompanying masks. Following match and action are currently supported for offload: Match: ether-protocol, IPv4/IPv6 addresses, L4 ports (TCP/UDP) Action: drop, redirect to another port on the device. Patch 3 adds support to offload tc-flower flows having vlan actions: pop, push, and modify. Patch 4 adds support to fetch stats for the offloaded tc flower flows from hardware. Support for offloading more match and action types are to be followed in subsequent series. v2: - Setting ftid to -1 not required after bitmap_find_free_region in cxgb4_get_free_ftid. - Direct return can be used as jumping to error path is not needed if flower entry allocation failed in cxgb4_tc_flower_replace. Same applies if flower entry not found in cxgb4_tc_flower_destroy. - Also, removed an extra return from cxgb4_tc_flower_destroy. - Avoid wrapping line for netdev_err message. Also, use consistent error message string. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Currently, there is a difference in netlink events received when an interface is modified through bridge ioctl() or through netlink. This patch generates additional events when an interface is added to or removed from a bridge via ioctl(). When adding then removing an interface from a bridge with netlink, we get: 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue master bridge0 state UNKNOWN group default link/ether 9e:da:60:ee:cf:c8 brd ff:ff:ff:ff:ff:ff 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 master bridge0 state UNKNOWN link/ether 9e:da:60:ee:cf:c8 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 master bridge0 state UNKNOWN link/ether 9e:da:60:ee:cf:c8 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 master bridge0 state UNKNOWN link/ether 9e:da:60:ee:cf:c8 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 master bridge0 state UNKNOWN link/ether 9e:da:60:ee:cf:c8 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue master bridge0 state UNKNOWN group default link/ether 9e:da:60:ee:cf:c8 brd ff:ff:ff:ff:ff:ff 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue master bridge0 state UNKNOWN group default link/ether 9e:da:60:ee:cf:c8 brd ff:ff:ff:ff:ff:ff 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 master bridge0 state UNKNOWN link/ether 9e:da:60:ee:cf:c8 Deleted 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 master bridge0 state UNKNOWN link/ether 9e:da:60:ee:cf:c8 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default link/ether 9e:da:60:ee:cf:c8 brd ff:ff:ff:ff:ff:ff When using ioctl(): 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue master bridge0 state UNKNOWN group default link/ether 9e:da:60:ee:cf:c8 brd ff:ff:ff:ff:ff:ff 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 master bridge0 state UNKNOWN link/ether 9e:da:60:ee:cf:c8 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 master bridge0 state UNKNOWN link/ether 9e:da:60:ee:cf:c8 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 master bridge0 state UNKNOWN link/ether 9e:da:60:ee:cf:c8 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue master bridge0 state UNKNOWN group default link/ether 9e:da:60:ee:cf:c8 brd ff:ff:ff:ff:ff:ff 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue master bridge0 state UNKNOWN group default link/ether 9e:da:60:ee:cf:c8 brd ff:ff:ff:ff:ff:ff 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 master bridge0 state UNKNOWN link/ether 9e:da:60:ee:cf:c8 Deleted 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 master bridge0 state UNKNOWN link/ether 9e:da:60:ee:cf:c8 5: dummy1: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default link/ether 9e:da:60:ee:cf:c8 brd ff:ff:ff:ff:ff:ff Without this patch, the last netlink notification is not sent.

Since commit 1dced6a8 ("ipv4: Restore accept_local behaviour in fib_validate_source()") a full fib lookup is needed even if the rp_filter is disabled, if accept_local is false - which is the default. What we really need in the above scenario is just checking that the source IP address is not local, and in most case we can do that is a cheaper way looking up the ifaddr hash table. This commit adds a helper for such lookup, and uses it to validate the src address when rp_filter is disabled and no 'local' routes are created by the user space in the relevant namespace. A new ipv4 netns flag is added to account for such routes. We need that to preserve the same behavior we had before this patch. It also drops the checks to bail early from __fib_validate_source, added by the commit 1dced6a8 ("ipv4: Restore accept_local behaviour in fib_validate_source()") they do not give any measurable performance improvement: if we do the lookup with are on a slower path. This improves UDP performances for unconnected sockets when rp_filter is disabled by 5% and also gives small but measurable performance improvement for TCP flood scenarios. v1 -> v2: - use the ifaddr lookup helper in __ip_dev_find(), as suggested by Eric - fall-back to full lookup if custom local routes are present Signed-off-by:

Joel Fernandes says: ==================== Add cross-compilation support to eBPF samples These patches fix issues seen when cross-compiling eBPF samples on arm64. Compared to [1], I dropped the controversial inline-asm patch and exploring other options to fix it. However these patches are a step in the right direction and I look forward to getting them into -next and the merge window. Changes since v3: - just a repost with acks [1] https://lkml.org/lkml/2017/8/7/417 ==================== Signed-off-by:

BPF samples fail to build when cross-compiling for ARM64 because of incorrect pt_regs param selection. This is because clang defines __x86_64__ and bpf_headers thinks we're building for x86. Since clang is building for the BPF target, it shouldn't make assumptions about what target the BPF program is going to run on. To fix this, lets pass ARCH so the header knows which target the BPF program is being compiled for and can use the correct pt_regs code. Acked-by:

When cross compiling, bpf samples use HOSTCC for compiling the non-BPF part of the sample, however what we really want is to use the cross compiler to build for the cross target since that is what will load and run the BPF sample. Detect this and compile samples correctly. Acked-by:

When cross-compiling the bpf sample map_perf_test for aarch64, I find that __NR_getpgrp is undefined. This causes build errors. This syscall is deprecated and requires defining __ARCH_WANT_SYSCALL_DEPRECATED. To avoid having to define that, just use a different syscall (getppid) for the array map stress test. Acked-by:
