Saeed Mahameed says: ==================== mlx5e-updates-2018-08-10 This series provides the following updates to mlx5e netdevice driver. 1) First 4 patches extends the support for ethtool rxnfc flow steering - Added ipv6 support - l4 proto ip field for both ip6 and ip4 2) Next 4 patches, reorganizing flow steering structures and declaration into one header file, and add two Kconfig flags to allow disabling/enabling mlx5 netdevice rx flow steering at compile time: CONFIG_MLX5_EN_ARFS for en_arfs.c CONFIG_MLX5_EN_RXNFC for en_fs_ehtool.c 3) More kconfig flags dependencies - vxlan.c depends on CONFIG_VXLAN - clock.c depends on CONFIG_PTP_1588_CLOCK 4) Reorganize the Makefile ==================== Signed-off-by:David S.

The last argument to mlx5_add_flow_rules passes the number of destinations in the struct pointed to by the dest arg. Change the name to better reflect this fact. Signed-off-by:

lib/clock.c includes clock related functions which require ptp support. Thus compile out lib/clock.c and add the needed function stubs in case kconfig CONFIG_PTP_1588_CLOCK is off. Signed-off-by:

When vxlan is not enabled by kernel, no need to enable it in mlx5. Compile out lib/vxlan.c if CONFIG_VXLAN is not selected. Signed-off-by:

Move ethool rxnfc callback into en_fs_etthool file where they belong. This will allow us to make many ethtool fs related helper functions static. Signed-off-by: -

Add support for l4 proto ip field in ethtool flow steering. Example: Redirect icmpv6 to rx queue #2 ethtool -U eth0 flow-type ip6 l4proto 58 action 2 Signed-off-by: -

Add ip6 support for ethtool flow steering. New supported flow types: ip6|tcp6|udp6| Supported fields: src-ip|dst-ip|src-port|dst-port Signed-off-by: -

Have a parsing function per flow type, that converts from ethtool rx flow spec to mlx5 flow spec. Will be useful to add support for ip6 ethtool flow steering in the next patch. Signed-off-by: -

Lockdep reports deadlock for following locking scenario in ife action: Task one: 1) Executes ife action update. 2) Takes tcfa_lock. 3) Waits on ife_mod_lock which is already taken by task two. Task two: 1) Executes any path that obtains ife_mod_lock without disabling bh (any path that takes ife_mod_lock while holding tcfa_lock has bh disabled) like loading a meta module, or creating new action. 2) Takes ife_mod_lock. 3) Task is preempted by rate estimator timer. 4) Timer callback waits on tcfa_lock which is taken by task one. In described case tasks deadlock because they take same two locks in different order. To prevent potential deadlock reported by lockdep, always disable bh when obtaining ife_mod_lock.

Would it be possible to get this one-liner fix pulled to net-next before you make your first 4.19 pull request for Linus? Thanks. ==================== Signed-off-by:

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-08-13 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add driver XDP support for veth. This can be used in conjunction with redirect of another XDP program e.g. sitting on NIC so the xdp_frame can be forwarded to the peer veth directly without modification, from Toshiaki. 2) Add a new BPF map type REUSEPORT_SOCKARRAY and prog type SK_REUSEPORT in order to provide more control and visibility on where a SO_REUSEPORT sk should be located, and the latter enables to directly select a sk from the bpf map. This also enables map-in-map for application migration use cases, from Martin. 3) Add a new BPF helper bpf_skb_ancestor_cgroup_id() that returns the id of cgroup v2 that is the ancestor of the cgroup associated with the skb at the ancestor_level, from Andrey. 4) Implement BPF fs map pretty-print support based on BTF data for regular hash table and LRU map, from Yonghong. 5) Decouple the ability to attach BTF for a map from the key and value pretty-printer in BPF fs, and enable further support of BTF for maps for percpu and LPM trie, from Daniel. 6) Implement a better BPF sample of using XDP's CPU redirect feature for load balancing SKB processing to remote CPU. The sample implements the same XDP load balancing as Suricata does which is symmetric hash based on IP and L4 protocol, from Jesper. 7) Revert adding NULL pointer check with WARN_ON_ONCE() in __xdp_return()'s critical path as it is ensured that the allocator is present, from Björn. ==================== Signed-off-by: -

The patches includes following change: *Use modern kvzalloc()/kvfree() instead of custom allocations. *Remove order argument for alloc_pg_vec, it can get from req. *Remove order argument for free_pg_vec, free_pg_vec now uses kvfree which does not need order argument. *Remove pg_vec_order from struct packet_ring_buffer, no longer need to save/restore 'order' *Remove variable 'order' for packet_set_ring, it is now unused Signed-off-by:

There is an unalignment access about the structure 'trace_event_raw_fib_table_lookup'. In include/trace/events/fib.h, there is a memory operation which casting the 'src' data member to a pointer, and then store a value to this pointer point to. p32 = (__be32 *) __entry->src; *p32 = flp->saddr; The offset of 'src' in structure trace_event_raw_fib_table_lookup is not four bytes alignment. On some architectures, they don't permit the unalignment access, it need to pay the price to handle this situation in exception handler. Adjust the layout of structure to avoid this case.

There have been two reports that network doesn't come back on resume from suspend when using MSI-X. Both cases affect the same chip version (RTL8168g - version 40), on different systems. Falling back to MSI fixes the issue. Even though we don't really have a proof yet that the network chip version is to blame, let's disable MSI-X for this version. Reported-by:
