Subject: [hurd,commited] socket: Fix tst-cmsghdr-skeleton.c use of cmsg_len
Date: Mon, 1 May 2023 15:06:07 +0200 [thread overview]
Message-ID: <20230501130607.3846669-1-samuel.thibault@ens-lyon.org> (raw)
cmsg_len is supposed to be socklen_t according to standards, but it was made
size_t on Linux, see BZ 16919. For ports that have it socklen_t, SIZE_MAX is
too large. We can however explicitly cast it to the type of cmsg_len so it
will fit according to that type.
