s3-lib: restore truncating behavior of push_ascii_nstring()
Some users of push_ascii_nstring() (notably name_to_unstring())
expect the output to be truncated if it would exceed the size of
an nstring after conversion. However this broke in 2011 due to
commit d546adeab5 ("Change convert_string_internal() and
convert_string_error() to bool return"). This patch restores the
old behavior.
The issue can be observed in syslog after setting the
``workgroup`` to a 16+ characters long string which triggers a
DEBUG() message:

subdir_of() calculates the share-relative rest for us, don't do the
strlen(connectpath) calculation twice. subdir_of() also checks that
the target properly ends on a directory. With just strncmp a symlink
to x->/aa/etc would qualify as in share /a, so a "get x/passwd" leads to a
pretty unfortunate result. This is the proper fix for bug 15207, so we
need to change the expected error code to OBJECT_PATH_NOT_FOUND

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.

lib/tsocket: avoid endless cpu-spinning in tstream_bsd_fde_handler()
There were some reports that strace output an LDAP server socket is in
CLOSE_WAIT state, returning EAGAIN for writev over and over (after a call to
epoll() each time).
In the tstream_bsd code the problem happens when we have a pending
writev_send, while there's no readv_send pending. In that case
we still ask for TEVENT_FD_READ in order to notice connection errors
early, so we try to call writev even if the socket doesn't report TEVENT_FD_WRITE.
And there are situations where we do that over and over again.
It happens like this with a Linux kernel:
tcp_fin() has this:
struct tcp_sock *tp = tcp_sk(sk);
So we'll get EPOLLIN | EPOLLRDNORM | EPOLLRDHUP triggering
TEVENT_FD_READ and writev/sendmsg keeps getting EAGAIN.
So we need to always clear TEVENT_FD_READ if we don't
have readable handler in order to avoid burning cpu.
But we turn it on again after a timeout of 1 second
in order to monitor the error state of the connection.
And now that our tsocket_bsd_error() helper checks for POLLRDHUP,
we can check if the socket is in an error state before calling the
writable handler when TEVENT_FD_READ was reported.
Only on error we'll call the writable handler, which will pick
the error without calling writev().

We often create imessaging contexts just for sending messages,
but we'll never process incoming messages because a temporary event
context was used and we just queue a lot of imessaging_post_state
structures with immediate events.
With imessaging_init_discard_incoming() we'll discard any incoming messages
unless we have pending irpc requests.

vfs_glusterfs: Add path based fallback mechanism for SMB_VFS_FNTIMES
Fallback mechanism was missing in vfs_gluster_fntimes() for path based
call. Therefore adding a similar mechanism as seen with other calls like
vfs_gluster_fsetxattr, vfs_gluster_fgetxattr etc.
smbXsrv_client: handle NAME_NOT_FOUND from smb2srv_client_connection_{pass,drop}()
If we get NT_STATUS_OBJECT_NOT_FOUND from smb2srv_client_connection_{pass,drop}()
we should just keep the connection and overwrite the stale record in
smbXsrv_client_global.tdb. It's basically a race with serverid_exists()
and a process that doesn't cleanly teardown.
smbXsrv_client: call smb2srv_client_connection_{pass,drop}() before dbwrap_watched_watch_send()
dbwrap_watched_watch_send() should typically be the last thing to call
before the db record is unlocked, as it's not that easy to undo.
In future we want to recover from smb2srv_client_connection_{pass,drop}()
returning NT_STATUS_OBJECT_NAME_NOT_FOUND and it would add complexity if
would need to undo dbwrap_watched_watch_send() at that point.
smbXsrv_client: ignore NAME_NOT_FOUND from smb2srv_client_connection_passed
If we hit a race, when a client disconnects the connection after the initial
SMB2 Negotiate request, before the connection is completely passed to
process serving the given client guid, the temporary smbd which accepted the
new connection may already detected the disconnect and exitted before
the long term smbd servicing the client guid was able to send the
MSG_SMBXSRV_CONNECTION_PASSED message.
and all connections belonging to the client guid were dropped,
because we called exit_server_cleanly().
Now we ignore NT_STATUS_OBJECT_NAME_NOT_FOUND from
smb2srv_client_connection_passed() and let the normal
event loop detect the broken connection, so that only
that connection is terminated (not the whole smbd process).
It was unnecessary to construct full directory path as "dir/." which is
same as "dir". We could just directly use fsp->fsp_name->base_name and
return directory stream obtained from glfs_opendir().

For type == ADOUBLE_META, fio->fake_fd is true so
writes are already synchronous, just call tevent_req_post().
For type == ADOUBLE_RSRC we know we are configured
with FRUIT_RSRC_ADFILE (because fruit_must_handle_aio_stream()
returned true), so we can just call SMB_VFS_NEXT_FSYNC_SEND()
after replacing fsp with fio->ad_fsp.
