Subject: [PATCH] selftests: net: csum: Fix printk format in recv_get_packet_csum_status()
Date: Tue, 13 Jan 2026 18:44:19 +0100 [thread overview]
Message-ID: <b0e24fd07302aac492d03d0bcd30626a338f976f.1768326133.git.chleroy@kernel.org> (raw)
CC csum
csum.c: In function 'recv_get_packet_csum_status':
csum.c:710:50: warning: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'size_t' {aka 'unsigned int'} [-Wformat=]
710 | error(1, 0, "cmsg: len=%lu expected=%lu",
| ~~^
| |
| long unsigned int
| %u
711 | cm->cmsg_len, CMSG_LEN(sizeof(struct tpacket_auxdata)));
| ~~~~~~~~~~~~
| |
| size_t {aka unsigned int}
csum.c:710:63: warning: format '%lu' expects argument of type 'long unsigned int', but argument 5 has type 'unsigned int' [-Wformat=]
710 | error(1, 0, "cmsg: len=%lu expected=%lu",
| ~~^
| |
| long unsigned int
| %u
Correct format from %lu to %u for both.
Fixes: 91a7de85600d ("selftests/net: add csum offload test")
