Subject: [PATCH v2 0/5] BPF enhancements
Date: Fri, 31 Oct 2025 09:41:44 -0700	[thread overview]
Message-ID: <20251031164417.14166-1-stephen@networkplumber.org> (raw)
In-Reply-To: <20251030173732.246435-1-stephen@networkplumber.org>

This is a series of fixes and tests for BPF functionality.
The new tests for Tx and Rx filtering require the infrastructure
to build a bpf program (clang) and the tool to convert object
file to header (xxd). If missing the test will get skipped.

v2 - add more checks in rx test
     fix headers 

Stephen Hemminger (5):
  bpf: add allocation annotations to functions
  bpf: use bulk free on filtered packets
  bpf: add a test for BPF ELF load
  bpf: add test for Rx and Tx filtering
  bpf: remove use of VLA
