From: Willem de Bruijn <willemb@google.com> stable inclusion from stable-v6.6.5 commit efd3358bc3d0f75554f110487a5d9133abb3f512 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8N21P Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 088559815477c6f623a5db5993491ddd7facbec7 ] Fix a small compiler warning. nr_process must be a signed long: it is assigned a signed long by strtol() and is compared against LONG_MIN and LONG_MAX. ipsec.c:2280:65: error: result of comparison of constant -9223372036854775808 with expression of type 'unsigned int' is always false [-Werror,-Wtautological-constant-out-of-range-compare] if ((errno == ERANGE && (nr_process == LONG_MAX || nr_process == LONG_MIN)) Fixes: bc2652b7ae1e ("selftest/net/xfrm: Add test for ipsec tunnel") Signed-off-by: Willem de Bruijn <willemb@google.com> Reviewed-by: Dmitry Safonov <0x7f454c46@gmail.com> Link: https://lore.kernel.org/r/20231124171645.1011043-2-willemdebruijn.kernel@gma...
