10:17 a.m.
How to reproduce:
1. mount the nfs-ganesha export directory with NFSV3
2. create new users: user1 and user2, there is the same user group for user1 and user2
uid=9998(user1) gid=100(users) groups=100(users)
uid=9997(user2) gid=100(users) groups=100(users)
3. log in using user1 and create new file named abc.txt
4. chmod 664 abc.txt
5. log in using user2, and write new content to abc.txt
echo 'Hello' > abc.txt
6. The error "Operation not permitted" will be output
Expected result:
user2 may write data to file abc.txt successfully.

The issue may be fixed by changing the following code, is it appropriate changes for
fixing the issue?

*state, struct attrlist *attrib_set)

if (FSAL_TEST_MASK(attrib_set->valid_mask, ATTR_ATIME_SERVER)) {
