Subject: [Patch bpf-next v3 0/5] sock_map: clean up and refactor code for BPF_SK_SKB_VERDICT
From: Cong Wang <cong.wang@...edance.com>
This patchset is the first series of patches separated out from
the original large patchset, to make reviews easier. This patchset
does not add any new feature or change any functionality but merely
cleans up the existing sockmap and skmsg code and refactors it, to
prepare for the patches followed up. This passed all BPF selftests.
The original whole patchset is available on github:
https://github.com/congwang/linux/tree/sockmap
and this patchset is also available on github:
https://github.com/congwang/linux/tree/sockmap1
---
v3: fix a few Kconfig compile errors
remove an unused variable
add a comment for bpf_convert_data_end_access()
v2: split the original patchset
compute data_end with bpf_convert_data_end_access()
get rid of psock->bpf_running
reduce the scope of CONFIG_BPF_STREAM_PARSER
do not add CONFIG_BPF_SOCK_MAP
Cong Wang (5):
bpf: clean up sockmap related Kconfigs
skmsg: get rid of struct sk_psock_parser
bpf: compute data_end dynamically with JIT code
skmsg: use skb ext instead of TCP_SKB_CB
sock_map: rename skb_parser and skb_verdict
