* daemon: fix up INTERNAL_SYSCALL() usageMike Frysinger2009-09-151-4/+6
| | | | | | | | | | | Make sure we declare the error properly in case a port uses it, and fix the invocation of exit(). Since clone() will be returning a pid, assume that the value will not have the MSB set (negative) to simplify the error test a bit more. If gcc supports it, force this function to always be heavily optimized in a bid to avoid stack usage as much as possible.

* fstatat: fix up behavior on 32/64 bit hostsMike Frysinger2009-09-064-2/+32
| | | | | | | | | | | | The fstatat() syscall is a little funky in that it sometimes changes name between 32 and 64 bit hosts, but it should always operate on a 64bit stat structure. So for the fstatat() function, make sure we convert it from a 64bit kstat to a 32bit stat. Along these lines, we need to restore the __xstat32_conv() function.

| | | | | | | | This reverts commit b1913a876059949e6c309bafade55e9425ef33fb. OABI is still a requirement. So we override the common syscall implementation specifically for arm port. Signed-off-by: Khem Raj <raj.khem@gmail.com>

* utent.c: fix a few bugs, and shrink a bitDenys Vlasenko2009-09-051-47/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
