We also remove some library checks for Heimdal components that we don't

The intention of this option was to hide *files*. Before this patch we
also hide directories where new files are dropped.
This is a change in behaviour, but I think this option is niche enough

s3:winbind: Avoid unnecessary locking in wb_parent_idmap_setup_send()
A function in tevent environment can span over several context loop iterations.
Every iteration 'unschedules' the current code and a different functions can
access not yet fully initialized structures.
A locking is used to avoid this. In tevent, we use tevent queues as a locking
mechanism. Every function trying to access lock protected data, puts itself to
a queue. The function must remove itself from the queue only after the complete
work is done.
A good coding practise is to lock only the smallest code path and not to use the
locking if not needed.
wb_parent_idmap_setup_send() uses queue "wb_parent_idmap_config_queue" for:
- testing if the setup is ready
- setting up all idmap domains
But "testing if the setup is ready" can be coded as an atomic operation without
needing a lock.

s3: smbd: Consistently map EAs to user namespace
Samba has always been mapping Windows EAs to the 'user' namespace on the
POSIX side. However, in the opposite direction, the mapping would also map
other user-readable POSIX EA namespaces to Windows EAs, only stripping the
'user' namespace prefix, and passing all other EA names verbatim.
This means any POSIX EA 'other.foo' collides with 'user.other.foo' on the
Windows side, hence the mapping of non-user namespaces is unreliable.
Also, copy operations via Windows would rename an existing POSIX EA
'other.foo' in the source file to 'user.other.foo' in the destination. The
'user' namespace, however, may not be enabled on the underlying filesystem,
leading to subtle failure modes like the ones reported in eg.
<https://bugzilla.samba.org/show_bug.cgi?id=15186>
Fix the issues by restricting the mapping to the 'user' POSIX EA namespace
consistently for either direction.

CVE-2022-3592 torture3: Show that our symlink traversal checks are insecure
This test shows that we don't properly check whether symlink targets
are inside the exported share. Linking to <share-root>a/etc makes us
loop back into filename_convert_dirfsp_nosymlink() with /etc as a
directory name.
On Linux systems with openat2(RESOLVE_NO_SYMLINKS) we pass "/etc"
directly into that call after some checks for "."/".." as invalid file
name components. "/etc" is okay for openat2(), but this test must also
succeed on systems without RESOLVE_NO_SYMLINKS (sn-devel-184 for
example). On systems without RESOLVE_NO_SYMLINKS split up the path
"/etc" into path components, in this case "" and "etc". So we pass ""
down to openat(), which correctly fails with ENOENT.
Summary: Only with RESOLVE_NO_SYMLINKS we're hit by bug 15207, and
this test shows by expecting CONNECTION_DISCONNECTED that we violate
the internal assumption of empty path components with an unexpected
symlink target, making it testable on systems with and without
RESOLVE_NO_SYMLINKS.

CVE-2022-3437 third_party/heimdal: Avoid undefined behaviour in _gssapi_verify_pad()
By decrementing 'pad' only when we know it's safe, we ensure we can't
stray backwards past the start of a buffer, which would be undefined
behaviour.
In the previous version of the loop, 'i' is the number of bytes left to
check, and 'pad' is the current byte we're checking. 'pad' was
decremented at the end of each loop iteration. If 'i' was 1 (so we
checked the final byte), 'pad' could potentially be pointing to the
first byte of the input buffer, and the decrement would put it one
byte behind the buffer.
That would be undefined behaviour.
The patch changes it so that 'pad' is the byte we previously checked,
which allows us to ensure that we only decrement it when we know we
have a byte to check.
As described by the C standard, __func__ is a variable, not a macro.
Hence this #ifndef check does not work as intended, and only serves to
unconditionally disable __func__. A nonoperating __func__ prevents
cmocka operating correctly, so remove this definition.
