--- Comment #17 from Kristof Provost <k...@freebsd.org> --- (In reply to fehmi noyan isi from comment #16) Yes, absolutely. The potential for integer overflow is a separate issue. I wouldn't try check_if_we_have_enough_memory() though. Memory allocation is very complicated and it's basically impossible to predict if there'd be enough free memory to satisfy a request without actually doing it. Moreover, it'd always be susceptible to races. I'd try to allocate the requested size with malloc(size * sizeof(foo), M_NOWAIT). If that fails we can fall back on malloc(DEFAULT_SIZE * sizeof(foo), M_WAITOK). Even that allocation might block forever, but at that point the system is so low on memory that we'll be in all sorts of trouble. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-pf@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-pf To unsubscribe, send any mail to "freebsd-pf-unsubscr...@freebsd.org"
