[Devel] [PATCH hci-8.1 v8 1/2] selftests: ve: grant the directories the files sit in

[no-reply at sashiko.virtuozzo.com]

> The sysfs variant names nested leaves, kernel/vmcoreinfo and
> kernel/notes, while the proc one names files at the top of the
> filesystem. Both enforcement tests grant the leaves and nothing else,
> so in the sysfs case the lookup stops at /sys/kernel, which a fresh VE
> cannot traverse, and every open answers ENOENT:
> 
>   not ok 14 ve_perms.sysfs.enforce_allows
>   not ok 15 ve_perms.sysfs.enforce_denies
> 
> Grant x on each directory along the way, taken from the path the
> variant already gives. set_entry() gets a PATH_MAX buffer and fails on
> truncation instead of writing a cut entry, as ve_open_rel() does.
