v5: - add a patch to cleanup before change: udp: little cleanup in udp_update_hdrX() to prepare future changes - see detailed v5 history log in each patch v4: - rebase - see detailed v4 history log in each patch v3: - add a patch that has been extracted from: "tcp: extract buffer management from tcp_send_flag()" -> "tcp: Introduce ipv4_fill_headers()/ipv6_fill_headers()" - see detailed v3 history log in each patch - I didn't address the alignment problem when we provide a pointer to a sub-structure in the internal buffer structure. (for the last patches of the series). v2 comparing to vhost-user full part: - part 1 includes only preliminary patches (checksum, iovec, cleanup) - see detailed v2 history log in each patch. Full series v1 available at: [PATCH 00/24] Add vhost-user support to passt. https://url.corp.redhat.com/passt-vhost-user-v1 Thanks, Laurent Laurent Vivier (9): pcap: add pcap_iov() checksum: align buffers checksum: add csum_iov() util: move IP stuff from util.[ch] to ip.[ch] udp: little cleanup in udp_update_hdrX() to prepare future changes checksum: use csum_ip4_header() in udp.c and tcp.c checksum: introduce functions to compute the header part checksum for TCP/UDP tap: make tap_update_mac() generic tcp: Introduce ipv4_fill_headers()/ipv6_fill_headers() Makefile | 10 +-- checksum.c | 174 +++++++++++++++++++++++++++++----------- checksum.h | 10 ++- conf.c | 1 + dhcp.c | 1 + flow.c | 1 + fwd.c | 1 + icmp.c | 1 + inany.c | 1 + ip.c | 72 +++++++++++++++++ ip.h | 86 ++++++++++++++++++++ ndp.c | 1 + pcap.c | 26 +++++- pcap.h | 1 + qrap.c | 1 + tap.c | 13 +-- tap.h | 2 +- tcp.c | 221 +++++++++++++++++++++++++++++---------------------- tcp_splice.c | 1 + udp.c | 82 ++++++++----------- util.c | 55 ------------- util.h | 76 ------------------ 22 files changed, 503 insertions(+), 334 deletions(-) create mode 100644 ip.c create mode 100644 ip.h -- 2.42.0
