This set makes the extack facility usable for returning such messages. The case in point here is spectrum and adding FIB rules which causes an offload abort. Make the use case more user friendly by letting the user know that offload is no longer happening because of the rule change. v2 - kept the offload abort in a work queue entry per Ido's comment David Ahern (3): netlink: Allow ext_ack to carry non-error messages net: Add extack to fib_notifier_info mlxsw: spectrum_router: Return extack message on abort due to fib rules .../net/ethernet/mellanox/mlxsw/spectrum_router.c | 108 +++++++++++++-------- include/net/fib_notifier.h | 1 + net/core/fib_rules.c | 9 +- net/ipv4/fib_trie.c | 13 ++- net/ipv6/ip6_fib.c | 15 +-- net/netlink/af_netlink.c | 18 ++-- 6 files changed, 99 insertions(+), 65 deletions(-) -- 2.1.4
