Subject: [PATCH v4 bpf-next 00/14] net: netfilter: add kfunc helper to update ct timeout
Date: Thu, 26 May 2022 23:34:48 +0200 [thread overview]
Message-ID: <cover.1653600577.git.lorenzo@kernel.org> (raw)
Changes since v3:
- split bpf_xdp_ct_add in bpf_xdp_ct_alloc/bpf_skb_ct_alloc and
bpf_ct_insert_entry
- add verifier code to properly populate/configure ct entry
- improve selftests
Changes since v2:
- add bpf_xdp_ct_add and bpf_ct_refresh_timeout kfunc helpers
- remove conntrack dependency from selftests
- add support for forcing kfunc args to be referenced and related selftests
Changes since v1:
- add bpf_ct_refresh_timeout kfunc selftest
Kumar Kartikeya Dwivedi (11):
bpf: Add support for forcing kfunc args to be referenced
bpf: Print multiple type flags in verifier log
bpf: Support rdonly PTR_TO_BTF_ID for pointer to const return value
bpf: Support storing rdonly PTR_TO_BTF_ID in BPF maps
bpf: Support passing rdonly PTR_TO_BTF_ID to kfunc
bpf: Whitelist some fields in nf_conn for BPF_WRITE
bpf: Define acquire-release pairs for kfuncs
selftests/bpf: Add verifier tests for forced kfunc ref args
selftests/bpf: Add C tests for rdonly PTR_TO_BTF_ID
selftests/bpf: Add verifier tests for rdonly PTR_TO_BTF_ID
selftests/bpf: Add negative tests for bpf_nf
Lorenzo Bianconi (3):
net: netfilter: add kfunc helper to update ct timeout
net: netfilter: add kfunc helpers to alloc and insert a new ct entry
selftests/bpf: add selftest for bpf_xdp_ct_add and
bpf_ct_refresh_timeout kfunc
