[PATCH v4 bpf-next 00/14] net: netfilter: add kfunc helper to update ct timeout

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
