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>

2017-01-11ash: commented-out possible fix for 7694Denys Vlasenko
bash has a feature: it restores termios after a successful wait for a foreground job which had at least one stopped or sigkilled member. The probable rationale is that SIGSTOP and SIGKILL can preclude task from properly restoring tty state. Should we do this too? A reproducer: ^Z an interactive python: $ python Python 2.7.12 (...) >>> ^Z { python leaves tty in -icanon -echo state. We do survive that... } [1]+ Stopped python { ...however, next program (python no.2) does not survive it well: } $ python Python 2.7.12 (...) >>> Traceback (most recent call last): { above, I typed "qwerty<CR>", but -echo state is still in effect } File "<stdin>", line 1, in <module> NameError: name 'qwerty' is not defined The implementation is modeled on bash code and seems to work. However, I'm not sure we should do this. For one: what if I'd fg the stopped python instead? It'll be confused by "restored" tty state. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
