Patch 2 :- Additional bit was added to support tai timestamp type to avoid tstamp drops in the forwarding path when testing TC-ETF. Patch is also updating bpf filter.c Some updates to bpf header files with introduction to BPF_SKB_CLOCK_TAI and documentation updates stating deprecation of BPF_SKB_TSTAMP_UNSPEC and BPF_SKB_TSTAMP_DELIVERY_MONO Patch 3:- Handles forwarding of UDP packets with TAI clock id tstamp_type type with supported changes for tc_redirect/tc_redirect_dtime to handle forwarding of UDP packets with TAI tstamp_type Abhishek Chauhan (3): net: Rename mono_delivery_time to tstamp_type for scalabilty net: Add additional bit to support clockid_t timestamp type selftests/bpf: Handle forwarding of UDP CLOCK_TAI packets include/linux/skbuff.h | 68 ++++++++++++++----- include/net/inet_frag.h | 4 +- include/uapi/linux/bpf.h | 15 ++-- net/bridge/netfilter/nf_conntrack_bridge.c | 6 +- net/core/dev.c | 2 +- net/core/filter.c | 54 ++++++++------- net/ieee802154/6lowpan/reassembly.c | 2 +- net/ipv4/inet_fragment.c | 2 +- net/ipv4/ip_fragment.c | 2 +- net/ipv4/ip_output.c | 14 ++-- net/ipv4/raw.c | 2 +- net/ipv4/tcp_output.c | 16 ++--- net/ipv6/ip6_output.c | 11 +-- net/ipv6/netfilter.c | 6 +- net/ipv6/netfilter/nf_conntrack_reasm.c | 2 +- net/ipv6/raw.c | 2 +- net/ipv6/reassembly.c | 2 +- net/ipv6/tcp_ipv6.c | 2 +- net/packet/af_packet.c | 7 +- net/sched/act_bpf.c | 4 +- net/sched/cls_bpf.c | 4 +- tools/include/uapi/linux/bpf.h | 15 ++-- .../selftests/bpf/prog_tests/ctx_rewrite.c | 10 +-- .../selftests/bpf/prog_tests/tc_redirect.c | 3 - .../selftests/bpf/progs/test_tc_dtime.c | 39 +++++------ 25 files changed, 172 insertions(+), 122 deletions(-)
