When an application sends TPM commands in NONBLOCKING mode
the driver holds chip->tpm_mutex returning from write(),
which triggers: "WARNING: lock held when returning to user space".
To fix this issue the driver needs to release the mutex before
returning and acquire it again in tpm_dev_async_work() before
sending the command.

The original code, before it was moved into security/keys/trusted-keys
had a flush after the blob unseal.  Without that flush, the volatile

either has to be rebooted or the TPM volatile area manually flushed.
Fix by adding back the lost flush, which we now have to export because

Pull AFS fixes from David Howells:
 "Fixes for AFS plus one patch to make debugging easier:

   - Fix how addresses are matched to server records. This is currently
     incorrect which means cache invalidation callbacks from the server
     don't necessarily get delivered correctly. This causes stale data
     and metadata to be seen under some circumstances.

   - Make the dynamic root superblock R/W so that rpm/dnf can reapply
     the SELinux label to it when upgrading the Fedora filesystem-afs
     package. If the filesystem is R/O, this fails and the upgrade
     fails.

     It might be better in future to allow setxattr from an LSM to
     bypass the R/O protections, if only for pseudo-filesystems.

   - Fix the parsing of mountpoint strings. The mountpoint object has to
     have a terminal dot, whereas the source/device string passed to
     mount should not. This confuses type-forcing suffix detection
     leading to the wrong volume variant being mounted.

   - Make lookups in the dynamic root superblock for creation events
     (such as mkdir) fail with EOPNOTSUPP rather than something like
     EEXIST. The dynamic root only allows implicit creation by the
     ->lookup() method - and only if the target cell exists.

   - Fix the looking up of an AFS superblock to include the cell in the
     matching key - otherwise all volumes with the same ID number are
     treated as the same thing, irrespective of which cell they're in.

   - Show the volume name of each volume in the volume records displayed
     in /proc/net/afs/<cell>/volumes. This proved useful in debugging as
     it provides a way to map the volume IDs to names, where the names
     are what appear in /proc/mounts"

There's no need to separately check for signals while inside the locked
region, since we're going to do "wait_event_interruptible()" right
afterwards anyway, and the error handling is much simpler there.

The check for whether we had already read anything was also redundant,
since we no longer do the odd merging of reads when there are pending
writers.

But perhaps more importantly, this adds commentary about why we still
need to wake up possible writers even though we didn't read any data,
and why we can skip all the finishing touches now if we get a signal (or
had a signal pending) while waiting for more data.

Fix missing cell comparison in afs_test_super().  Without this, any pair
volumes that have the same volume ID will share a superblock, no matter the
cell, unless they're in different network namespaces.

Normally, most users will only deal with a single cell and so they won't
see this.  Even if they do look into a second cell, they won't see a
problem unless they happen to hit a volume with the same ID as one they've
already got mounted.

Each AFS mountpoint has strings that define the target to be mounted.  This
is required to end in a dot that is supposed to be stripped off.  The
string can include suffixes of ".readonly" or ".backup" - which are
supposed to come before the terminal dot.  To add to the confusion, the "fs
lsmount" afs utility does not show the terminal dot when displaying the
string.

The kernel mount source string parser, however, assumes that the terminal
dot marks the suffix and that the suffix is always "" and is thus ignored.
In most cases, there is no suffix and this is not a problem - but if there
is a suffix, it is lost and this affects the ability to mount the correct
volume.

The command line mount command, on the other hand, is expected not to
include a terminal dot - so the problem doesn't arise there.

Fix this by making sure that the dot exists and then stripping it when
passing the string to the mount configuration.

afs_find_server tries to find a server that has an address that
matches the transport address of an rxrpc peer.  The code assumes
that the transport address is always ipv6, with ipv4 represented
as ipv4 mapped addresses, but that's not the case.  If the transport
family is AF_INET, srx->transport.sin6.sin6_addr.s6_addr32[] will
be beyond the actual ipv4 address and will always be 0, and all
ipv4 addresses will be seen as matching.

As a result, the first ipv4 address seen on any server will be
considered a match, and the server returned may be the wrong one.

One of the consequences is that callbacks received over ipv4 will
only be correctly applied for the server that happens to have the
first ipv4 address on the fs_addresses4 list.  Callbacks over ipv4
from all other servers are dropped, causing the client to serve stale
data.

This is fixed by looking at the transport family, and comparing ipv4
addresses based on a sockaddr_in structure rather than a sockaddr_in6.
