Denys Vlasenko	7b25b1c5b2	hush: do not leak script fds into NOEXEC children We set all opened script fds to CLOEXEC, thus making then go away after fork+exec. Unfortunately, CLOFORK does not exist. NOEXEC children will still see those fds open. For one, "ls" applet is NOEXEC. Therefore running "ls -l /proc/self/fd" in a script from standalone shell shows this: lrwx------ 1 root root 64 Aug 20 15:17 0 -> /dev/pts/3 lrwx------ 1 root root 64 Aug 20 15:17 1 -> /dev/pts/3 lrwx------ 1 root root 64 Aug 20 15:17 2 -> /dev/pts/3 lr-x------ 1 root root 64 Aug 20 15:17 3 -> /path/to/top/level/script lr-x------ 1 root root 64 Aug 20 15:17 4 -> /path/to/sourced/SCRIPT1 ... with as many open fds as there are ". SCRIPTn" nest levels. Fix it by closing these fds after fork (only for NOEXEC children). Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2016-08-20 15:58:34 +02:00

Denys Vlasenko	215b0ca6e4	hush: fix a bug in FEATURE_SH_STANDALONE=y config. Closes 9186 Run this in a "sh SCRIPT": sha256sum /dev/null echo END sha256sum is a NOEXEC applet. It runs in a forked child. Then child exit()s. By this time, entire script is read, and buffered in a FILE object from fopen("SCRIPT"). But fgetc() did not consume entire input. exit() lseeks back by -9 bytes, from <eof> to 'e' in 'echo'. (this may be libc-specific). This change of fd position is shared with the parent! Now parent can read more, and it thinks there is another "echo END". End result: two "echo END"s are run. Fix this by _exit()ing instead.
