Add a test that sends a tpm cmd in an async mode. Currently there is a gap in test coverage with regards to this functionality.

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 handles increase in the TPM until it becomes unusable and the system 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 of the relocation of the trusted key code may cause the consumer to be modular.

KEYS_COMPAT now always takes the value of COMPAT && KEYS. But the security/keys/ directory is only compiled if KEYS is enabled, so in practice KEYS_COMPAT is the same as COMPAT.

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" * tag 'afs-fixes-20191211' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: afs: Show volume name in /proc/net/afs/<cell>/volumes afs: Fix missing cell comparison in afs_test_super() afs: Fix creation calls in the dynamic root to fail with EOPNOTSUPP afs: Fix mountpoint parsing afs: Fix SELinux setting security label on /afs afs: Fix afs_find_server lookups for ipv4 peers

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. [ This is a split-out cleanup from my "make pipe IO use exclusive wait queues" thing, which I can't apply because it triggers a nasty bug in the GNU make jobserver - Linus ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

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.

David Howells authored
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.

We can see if a file was successfully opened for read and or for write by looking at file->f_mode. When writes are flowing from the page cache, file is no longer available. We can trust the VFS to have checked file->f_mode before writing to the page cache. The mode of a file might change between when it is opened and IO commences, or it might be created with an arbitrary mode. We'll make sure we don't hit EACCES during the IO stage by using UID 0" [ This is "posixish", but not a great solution in the long run, since a proper secure network server shouldn't really trust the client like this. But proper and secure POSIX behavior requires an open method and a resulting cookie for IO of some kind, or similar. - Linus ] * tag 'for-linus-5.5-ofs1' of git://git.kernel.org/pub/scm/linux/kernel/git/hubcap/linux: orangefs: posix open permission checking...
