The following reply was made to PR threads/75795; it has been noted by GNATS. From: Roman Nikitchenko <roman@trifle.net> To: freebsd-gnats-submit@FreeBSD.org, roman@trifle.net Cc: Subject: Re: threads/75795: applications linked with -lc_r can't close() fd opened by kqueue(). Date: Wed, 05 Jan 2005 11:33:04 +0200 The reason was in unimplemented kqueue_stat() call (libc_r close() relays on fstat() ). Here is my own version (sys/kern/kern_event.c) i used to workaround problem: /*ARGSUSED*/ static int kqueue_stat(struct file *fp, struct stat *st, struct ucred *active_cred, struct thread *td) { struct kqueue *kq; int error; if ((error = kqueue_aquire(fp, &kq))) return ENOENT; KQ_LOCK(kq); bzero((void *)st, sizeof(*st)); st->st_size = kq->kq_count; kqueue_release(kq, 1); KQ_UNLOCK(kq); st->st_blksize = sizeof(struct kevent); st->st_mode = S_IFIFO; return (0); } Please check / apply this as soon as possible. Any binary transfered from 4.x system and using kevent() subsystem won't work until this will be done. Any application with kevent()'s linked against libc_r too. -- WBR, Roman Nikitchenko, http://smartgate.wtelecom.net _,,,_|\_/|_,,,_
