Hi,
During my firewall configuration I noticed strange behaviour of ipfw option
uid.
ip_fw2.c:1513
#if __FreeBSD_version < 500034
#define socheckuid(a,b) ((a)->so_cred->cr_uid == (b))
#endif
if (cmd->opcode == O_UID) {
match =
socheckuid(pcb->inp_socket,
(uid_t)((ipfw_insn_u32 *)cmd)->d[0]);
} else {
Whereas the /sys/kern/uipc_socket.c:1844
int
socheckuid(struct socket *so, uid_t uid)
{
if (so == NULL)
return (EPERM);
if (so->so_cred->cr_uid == uid)
return (0);
return (EPERM);
}
Definitions found in macro code and function are incompatible. Thus following
patch:
