2017-07-15ash: protect WIFSTOPPED use with #if JOBSJohannes Schindelin
This change fixes the build in setups where there are no headers defining WIFSTOPPED and WSTOPSIG (where JOBS has to be set to 0). This partially reverts 4700fb5be (ash: make dowait() a bit more readable. Logic is unchanged, 2015-10-09).

2017-01-31ash: improve / fix glob expansionFelix Fietkau
When using musl libc glob() a very long string can cause glob() to fail, which leads to an out of memory error being raised by ash. This can happen easily if a very long quoted string contains *, even though no glob expansion should ever be performed on it (since it's quoted). Fix this by properly parsing control characters and escaping and only accept unquoted metacharacters. While we're at it, unify this check for libc and built-in glob expansion Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
