We should, but we don't. 2.4 does the right thing.
2.2 got the following change back in 2.2.6:
res = PTR_ERR(dentry);
if (!IS_ERR(dentry)) {
res = permission(dentry->d_inode, mode);
+ /* SuS v2 requires we report a read only fs too */
+ if(!res && (mode & S_IWOTH) && IS_RDONLY(dentry->d_inode))
+ res = -EROFS;
dput(dentry);
}
... and that's what really ticks me off - permission() does the right
tests in case of read-only fs (ignoring the r/o vs. r/w for devices and
FIFOs), but sys_access() explicitly overrides that.
IMO we should revert that in 2.2. HP/UX is probably hopeless - if they
will ever start caring about bogus behaviour access() will not be anywhere
near the top of their list ;-/
Yes. Alan, it seems we all agree that
