* ash: expand: Fixed "$@" expansion when EXP_FULL is falseDenys Vlasenko2016-10-022-0/+37
| | | | | | | | | | | | | | | | | | | Upstream commit: Date: Thu, 1 Jan 2015 07:53:10 +1100 expand: Fixed "$@" expansion when EXP_FULL is false The commit 3c06acdac0b1ba0e0acdda513a57ee6e31385dce ([EXPAND] Split unquoted $@/$* correctly when IFS is set but empty) broke the case where $@ is in quotes and EXP_FULL is false. In that case we should still emit IFS as field splitting is not performed.

* hush: fix a bug in FEATURE_SH_STANDALONE=y config. Closes 9186Denys Vlasenko2016-08-191-1/+2
| | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
