utent.c: fix a few bugs, and shrink a bit
bug #1: static_fd = -1; close(static_fd); DOH! bug #2: if (utmp_fd == -1) { __setutent(); } if (utmp_fd == -1) { return NULL; } if utmp_fd == -1, we call _setutent(). if __setutent() opens a fd, utmp_fd (a parameter) wouldn't change, the second check is bogus. We need to use static_fd instead in second check. Which makes clear that having utmp_fd parameter is wrong. See the patch for a complete fix. Shrink comes from simplifying fcntl(static_fd, F_SETFD, FD_CLOEXEC): text data bss dec hex filename - 661 8 384 1053 41d libc/misc/utmp/utent.o + 604 8 384 996 3e4 libc/misc/utmp/utent.o Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
