Description

Some flags setted in ACCESS request are cause of wrong returned access_mode

#1

Updated by Daniil Lunev about 8 years ago

If we ask for ACCESS4_MODIFY or ACCESS4_EXTEND (but not both), in response server sets both these bits up, and access_mode, that client recieves, is wrong because it's not a subset of requested mode.

#2

Updated by Daniil Lunev about 8 years ago

The following results in wrong access_mode bits returned by NFSv4 server:
- Client sends ACCESS request with ACCESS4_MODIFY flag or ACCESS request with ACCESS4_EXTEND flag
- Server returns both MODIFY and EXTEND bits set
