Subject: [PATCH bpf-next v8 0/3] Replace mono_delivery_time with tstamp_type
Date: Thu, 9 May 2024 14:18:31 -0700 [thread overview]
Message-ID: <20240509211834.3235191-1-quic_abchauha@quicinc.com> (raw)
Patch 1 :- This patch takes care of only renaming the mono delivery
timestamp to tstamp_type with no change in functionality of
existing available code in kernel also
Starts assigning tstamp_type with either mono or real and
introduces a new enum in the skbuff.h, again no change in functionality
of the existing available code in kernel , just making the code scalable.
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
