Subject: Re: [PATCH v6 06/26] perf trace: Copy sockaddr arguments by their length
Date: Mon, 28 Sep 2026 18:38:41 +0000 [thread overview]
Message-ID: <20260928183841.A10301F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260928182605.3649015-7-irogers@google.com>
> The BTF augmenter copies sizeof(struct sockaddr), 16 bytes, for the
> sockaddr arguments of connect, bind and sendto, and runs before the
> sys_enter_connect and sys_enter_sendto programs that copy their length.
> An IPv6 address needs 24 or 28 bytes, so the rest was read from past the
> payload, and now that the printers are bounded only its family is shown.
>
> Copy them as buffers sized by the length argument after them, up to the
> 32 bytes augmented buffers are limited to. That holds an IPv6 address
> and doubles the AF_LOCAL path shown.
