As with TCP, it turns out that there are a bunch of clean ups and reworks to the ICMP code which will make integration with the flow table easier, even before introducing a non-trivial version of the flow table itself. Based on the flow based dispatch/allocation, and bind/addressing cleanup series. Changes since v1: * Rebased on newer version of flow dispatch & allocation series * Added 12/12 splitting out close and new sequence functions David Gibson (12): checksum: Don't use linux/icmp.h when netinet/ip_icmp.h will do icmp: Don't set "port" on destination sockaddr for ping sockets icmp: Remove redundant initialisation of sendto() address icmp: Don't attempt to handle "wrong direction" ping socket traffic icmp: Don't attempt to match host IDs to guest IDs icmp: Use -1 to represent "missing" sockets icmp: Simplify socket expiry scanning icmp: Share more between IPv4 and IPv6 paths in icmp_tap_handler() icmp: Consolidate icmp_sock_handler() with icmpv6_sock_handler() icmp: Warn on receive errors from ping sockets icmp: Validate packets received on ping sockets icmp: Dedicated functions for starting and closing ping sequences checksum.c | 2 +- icmp.c | 326 ++++++++++++++++++++++++++--------------------------- icmp.h | 5 +- passt.c | 4 +- 4 files changed, 164 insertions(+), 173 deletions(-) -- 2.43.0
