LINUX: Avoid premature RO volume lock error
Commit 0fc27471e7da0c5de4addcdec1bfbca5208072cc avoids processing lock
requests for RO volumes, but it did this both in afs_lockctl() and in
the Linux-specific afs_linux_lock(). The changes in afs_linux_lock()
are incorrect, since they also avoid F_GETLK requests (whereas
afs_lockctl() just avoids F_SETLK* requests).
Additionally, the section in afs_linux_lock() incorrectly reports an
error, since it returns a positive EBADF error code, when we are
supposed to return -EBADF.
The result of all of this is that an F_GETLK F_WRLCK request for an RO
volume always fails with fcntl() returning 9 (EBADF), which is an
invalid return code for fcntl() F_GETLK (instead we should return -1
with an errno of 9). But if there are no locks, we should return
success anyway.
Just remove this section, since afs_lockctl() handles this case itself
anyway.

LINUX: Drop dentry if lookup returns new file
Background: when an entry is looked up after its parent changes,
afs_linux_dentry_revalidate re-looks-up the entry name in its parent.
If we get an ENOENT back, we d_drop the dentry, and in any other
situation we just d_invalidate it. As discussed in prior commits 997f7fce437787a45ae0584beaae43affbd37cce and 389473032cf0b200c2c39fd5ace108bdc05c9d97, we cannot simply d_drop the
dentry in all cases, because that would cause legitimate directories
to be reported as "deleted" if we just failed to lookup the entry due
to e.g. transient network errors (this causes, among other things,
'getcwd' to fail with ENOENT).
However, this logic has problems if the dentry name still exists, but
points to a different file; the case where 'tvc != vcp' in
afs_linux_dentry_revalidate. If that case happens, and the dentry is
still held open by some process, we will continue to try to reference
the vcache pointed to by the 'old' dcache entry, which is incorrect.
To maybe more clearly illustrate the issue, consider the following
cases:
$ sleep 9999 < /afs/localcell/testvol.ro/dir1/file1 &
$ rm -rf /afs/localcell/testvol.rw/dir1
$ mkdir /afs/localcell/testvol.rw/dir1
$ vos release testvol
$ ls -l /afs/localcell/testvol.ro
ls: cannot access /afs/localcell/testvol.ro/dir1: No such file or directory
total 0
d????????? ? ? ? ? ? dir1
Here, on the last 'ls', afs_linux_dentry_revalidate will afs_lookup
'dir1', and notice that it points to a different file (tvc != vcp),
and will d_invalidate the dentry. But since the file is still held
open, the dentry doesn't go away, and so we are still pointing to the
vcache for the old, deleted 'dir1'. That file doesn't exist anymore on
the fileserver, so we get an ENOENT when actually trying to stat() it
(we get a VNOVNODE from the fileserver, whcih gets translated to an
ENOENT).
A possibly more serious case is when the file is just renamed:
In this situation, the same code path applies, but the old file still
exists, so we will continue to use it without error. But since we are
still pointing at the old file, of course the results are incorrect.
Once we kill the process holding the file open, the bad dentry finally
goes away and the results are valid again.
To fix this behavior, d_drop the dentry in all cases, except when we
encounter an error preventing the lookup from being done. This ensures
that the dentry is unhashed from the parent directory in the scenarios
above, and so cannot be used for a subsequent lookup.
With this change, the only afs_lookup response that causes a simple
d_invalidate is when we encounter actual errors during the lookup
(such as transient network failures). This is correct, since in those
cases we don't _know_ that the dentry is wrong. For all other cases,
we do know that the dentry is wrong and so we must force it to be
unhashed.

comerr: compile_et -emit option for parallel make
Add the -emit option to the compile_et command to support parallel make.
The -emit option allows make to generate the header and the source files
independently, instead of building two files at the some time. This
avoids the issue where one command creates two separate files, which is
difficult to handle correctly for parallel makes.

libafs: Speed up afs_CheckTokenCache
On systems with a large number of PAGs and files in use, the
periodic daemon job that checks for expired credentials and
cleans up the axs cache can run for a very long time. This
can lead to kernel soft lockups and eventually hang processes
and file access because of unavailable locks.
Rework the scanning logic in afs_CheckTokenCache to make the
scanning more efficient in most real world cases. On a test
system accessing ~4000 files from processes in 1000 PAGs, this
has been observed to reduce the runtime of afs_CheckTokenCache
from a problematic ~70s down to about 0.7s.
Additionally, this changes the conditions in which an axscache is
discarded. uid+cell (rather than just uid) must now match, and
if no matching unixuser is found, it will also be discarded.
Adapted from code from Jeffrey Altman who provided the original
loop algorithm and code.

ptserver: Fix RemoveFromSGEntry hentry memcpy
In this function, hentry is the "previous" continuation entry that we
looked at, and centry is the "current" continuation entry. We keep
track of the previous continuation entry in case we need to update its
'next' pointer, which we do if we free one of the continuation entries
because it is empty after the removal.
So, this memcpy is supposed to copy the current entry to the previous
one, but the arguments are flipped, so we just copy zeroes to centry
(since hentry is initialized to zeroes early on in the function), and
hentry never gets set to anything besides zeroes.
The effect of this is that whenever a ptdb entry has more than one
continuation entry, and we free up any of them after the first one via
RemoveFromSGEntry, the previous continuation entry becomes blanked
(though the 'next' pointer should still be correct). This means the
membership information for that group is not recorded correctly, as it
loses a chunk of the IDs that it is a member of. The reverse mapping
should still be intact (the parent groups have a pointer to the
sub-group), but the group probably doesn't function correctly.
The reason this happened is because of the confusing conversion from
bcopy to memcpy. Most of the instances of bcopy/bcmp/bzero/etc were
converted (correctly) back in commit c5c521af, but the supergroups
implementation was added afterwards, in 8ab7a909, and contained a
bcopy reference. This bcopy was converted to memcpy in 58d5f38b, but
the argument order was not corrected, causing this bug.
To fix this, just flip the first two arguments of the memcpy. Just get
rid of the casts here, too, to match the code in the non-supergroups
RemoveFromEntry and elsewhere.
