On other systems, SI_LWP is generated by lwp_kill(). This will allow conforming applications to differentiate between signals generated by standard events and those generated by other implementation events in a manner compatible with existing practice. - Bump __FreeBSD_version Modified: head/sys/kern/kern_thr.c head/sys/sys/signal.h Modified: head/sys/kern/kern_thr.c ============================================================================== --- head/sys/kern/kern_thr.c Tue Aug 24 06:30:46 2010 (r211731) +++ head/sys/kern/kern_thr.c Tue Aug 24 07:22:24 2010 (r211732) @@ -312,7 +312,7 @@ thr_kill(struct thread *td, struct thr_k error = 0; ksiginfo_init(&ksi); ksi.ksi_signo = uap->sig; - ksi.ksi_code = SI_USER; + ksi.ksi_code = SI_LWP; ksi.ksi_pid = p->p_pid; ksi.ksi_uid = td->td_ucred->cr_ruid; PROC_LOCK(p); @@ -371,7 +371,7 @@ thr_kill2(struct thread *td, struct thr_ if (error == 0) { ksiginfo_init(&ksi); ksi.ksi_signo = uap->sig; - ksi.ksi_code = SI_USER; + ksi.ksi_code = SI_LWP; ksi.ksi_pid = td->td_proc->p_pid; ksi.ksi_uid = td->td_ucred->cr_ruid; if (uap->id == -1) { Modified: head/sys/sys/signal.h ============================================================================== --- head/sys/sys/signal.h Tue Aug 24 06:30:46 2010 (r211731) +++ head/sys/sys/signal.h Tue Aug 24 07:22:24 2010 (r211732) @@ -338,6 +338,7 @@ struct sigaction { #define SI_MESGQ 0x10005 /* Signal generated by arrival of a */ /* message on an empty message queue. */ #define SI_KERNEL 0x10006 +#define SI_LWP 0x10007 /* Signal sent by thr_kill */ #endif #if __BSD_VISIBLE #define SI_UNDEFINED 0
