Logged In: YES user_id=75003 Ref.impl. V1. Simple escalation. Allows the VFS to shoot itself in the foot by opening a channel R only, getting it W in close, and trying to write, failing, maybe crashing. Tomorrow we will extend that to keep max and effective perms around. andreas_kupries added on 2004-11-02 06:45:50:

File Added - 107388: tip220-v2.patch.gz Logged In: YES user_id=75003 Ref.impl. v2. Store max perms as well, ensure that the channel will not get more privileges on restore than it had at creation time. | ||||
