List,

Please find a small test for cifs that tests that setfattr -x for a non existing attribute will fail correctly.
This is for a bug we recently fixed in cifs.ko where we used to return successr, since that is what the SMB2 response 
from the server would be.

Xfstests already have testing for setfattr -x for nonexisting attributes in generic/097 but we can not use that test in cifs since we
can only allow the use of the user namespace. (No way to lock down access to read/write EA subspaces such as 'system.' prefixes and such.)

Since tests only tests a small subset of generic/097 it made more sense to me to add this as a cifs specific
test instead of adding a new, redundant, generic/* test.

We just fixed a bug in cifs.ko where it would incorrectly return success
for setfattr -x user.does-not-exist.

This patch adds a test case for this.

Xfstests already have tests for setfattr -x in generic/097
but we can not yet use that test for cifs since we can only support
the user namespace.

Hi Ronnie,

Probably better to send this (and any followups) to the fstests
list... :)

'the "user." xattr namespace.'

"user namespace" is an overloaded term.

Why? And it doesn't get cleaned up on test exit, either.

I don't see anything cifs specific in this test.

And why just test this one specific thing you found a bug in? Why
not just copy all of generic/097 and chop out all the non-"user."
xattr namespace bits so you exercise all the different xattr
operations?

Cheers,

Dave.
