Subject: [PATCH] bpf: Fix BPF_PROG_ASSOC_STRUCT_OPS last field check
Date: Thu, 18 Jun 2026 14:09:33 +1000	[thread overview]
Message-ID: <20260618040934.4113938-1-tweek@google.com> (raw)

When struct prog_assoc_struct_ops was added,
BPF_PROG_ASSOC_STRUCT_OPS_LAST_FIELD referenced prog_fd instead of the
actual last field, flags.

Fixes: b5709f6d26d6 ("bpf: Support associating BPF program with struct_ops")
