On the few kernel versions before struct key.uid was converted to
kuid_t (v3.7-rc1~147^2~76), it was not possible to enable both
CONFIG_KEYS and CONFIG_UIDGID_STRICT_TYPE_CHECKS, so this case was
impossible. That’s good, because it also had a typo in its
implementation (and was confusing to deal with correctly).

With CONFIG_UIDGID_STRICT_TYPE_CHECKS (a dependency of user namespace
support, CONFIG_USER_NS) turned on, uid_t and kuid_t are different
types, as are gid_t and kgid_t, and we need to use namespace-dependent
functions to convert between them.
We can’t use init_user_ns as the namespace because it’s GPL-only, so
instead we grab the current user_ns at module load time.
This is required to support kernels with user namespace support. We
don’t yet have full support for independent AFS use by different users
in a multiuser container; that will need to wait for future work.

com_err.h can be in com_err.h, et/com_err.h, or krb5/com_err.h (for
netbsd 6.1 and possibly other netbsd). aklog currently only includes
either com_err.h or et/com_err.h, depending on autoconf probes
performed by the krb5.m4 macros.
So, also look for krb5/com_err.h. The krb5.m4 macros currently only
look for com_err.h at all if certain other libkrb5 tests return
certain results, so just look for all of them directly in some of our
openafs-specific krb5 probing logic in configure.ac.
Also remove the duplicate check for et/com_err.h in acinclude.m4 while
we're here. We only use et/com_err.h if krb5 support is enabled, so
only check for it in the second of krb5 probes.

The context is passed into the new dir_emit function that will

The new dir_emit function returns true on success, so we must be

Replace the existing test with a more robust one that checks for
the existence of the new filename structure. Since older kernels
are expected to fail this test, we'll get the correct result even
if there is unrelated failure, for instance a missing/different

Currently, we try to invalidate other dentries that exist for a
particular dir inode when we look up a dentry. This is so we try to
avoid duplicate dentries for a directory, which Linux does not like
(you cannot have hardlinks to a dir).
If we cannot invalidate the other aliases (because they are being
used), right now we just return the alias. This can make it very easy
to panic the client, due to the sanity checks Linux performs when dong
things like 'rmdir'. If we do something like this:
mkdir dir1
fs mkm dir1/mtpt vol
mkdir dir1/mtpt/dir2
fs mkm dir1/mtpt/dir2/mtpt2 vol
cd dir1/mtpt
rmdir dir2/mtpt2
For the 'rmdir', we will lookup 'mtpt2'. Since 'mtpt' and 'mtpt2'
are mountpoints for the same volume, their dentries point to the same
directory inode. So when we lookup 'mtpt2', we will try to invalidate
the other dentry, but we cannot do that since it is the cwd. So we
return the alias dentry (for 'mtpt'). The Linux VFS layer then does a
sanity check for the rmdir operation, checking that the child dentry's
parent inode is the same as the inode we're performing the rmdir for.
Since the dentry we returned was for 'mtpt', whose parent is 'dir1',
and the actual dir we're performing the rmdir for is 'dir2', this
sanity check fails and we BUG.
To avoid this, make the dentry alias act like a symlink when we
encounter an uninvalidateable dentry alias. That is, we allow multiple
dentry aliases for a directory, however, when the dentry aliases are
actually used, we redirect to a common dentry (via d_automount where
possible, and follow_link elsewhere).
This means that such mountpoints will behave similarly to symlinks, in
that we 'point' to a specific mountpoint dentry. This means that if we
have multiple different ways to get to the same volume, and all are
accessed at the same time, all but one of those mountpoints will
behave like symlinks, pointing to the same mountpoint. So, the '..'
entries for each path will all point to the parent dir of one
mountpoint, meaning that the '..' entry will be "wrong", but for most
cases it will still be correct.
In order to try to make the 'target', pointed-to directory consistent,
we add a new field to struct vcache: target_link. This points to the
dentry we should redirect to, whenever that vcache is referenced. To
avoid (possibly not-feasibly-solvable) problems with refcounting, this
pointer is not actually a reference to the target dentry, but just
serves as a pointer to compare to.
