https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=214881 Konstantin Belousov <kib@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jamie@FreeBSD.org, | |kib@FreeBSD.org --- Comment #1 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to aler from comment #0) I suspect that this is just a thinko, the case path == NULL is handled later. OTOH, it is not clear to me that path == NULL should result in the '0' addend to len in the check. If you do consider the right action to be cleanup, then the failing len check already provides an example what to do. Anyway, I am attaching patch with simple additional check for path == NULL. -- You are receiving this mail because: You are the assignee for the bug.home | help
