samba_start_debugger() attempts to start a debugger attached to the
calling process by calling system() to start a background process.
However, if the spawned shell exits before the debugger has had a chance
to attach, the debugger process will no longer be a child of the parent
process (as it will have been reparented).
If the system does not allow tracing by non-child processes, attachment
may fail as a result.
This commit replaces the system() call and the implicit shell around
xterm with an explicit fork()/exec() so that the debugger remains a
child of the calling process, ensuring the attachment succeeds unless
tracing is disabled completely.

A DN string with lots of trailing space can cause ldb_dn_explode() to
put a zero byte in the wrong place in the heap.
When a DN string has a value represented with trailing spaces,
like this
"CN=foo ,DC=bar"
the whitespace is supposed to be ignored. We keep track of this in the
`t` pointer, which is NULL when we are not walking through trailing
spaces, and points to the first space when we are. We are walking with
the `p` pointer, writing the value to `d`, and keeping the length in
`l`.
"CN=foo ,DC= " ==> "foo "
^ ^ ^
t p d
--l---
The value is finished when we encounter a comma or the end of the
string. If `t` is not NULL at that point, we assume there are trailing
spaces and wind `d and `l` back by the correct amount. Then we switch
to expecting an attribute name (e.g. "CN"), until we get to an "=",
which puts us back into looking for a value.
Unfortunately, we forget to immediately tell `t` that we'd finished
the last value, we can end up like this:
"CN=foo ,DC= " ==> ""
^ ^ ^
t p d
l=0
where `p` is pointing to a new value that contains only spaces, while
`t` is still referring to the old value. `p` notices the value ends,
and we subtract `p - t` from `d`:
"CN=foo ,DC= " ==> ? ""
^ ^ ^
t p d
l ~= SIZE_MAX - 8
At that point `d` wants to terminate its string with a '\0', but
instead it terminates someone else's byte. This does not crash if the
number of trailing spaces is small, as `d` will point into a previous
value (a copy of "foo" in this example). Corrupting that value will
ultimately not matter, as we will soon try to allocate a buffer `l`
long, which will be greater than the available memory and the whole
operation will fail properly.
However, with more spaces, `d` will point into memory before the
beginning of the allocated buffer, with the exact offset depending on
the length of the earlier attributes and the number of spaces.
What about a longer DN with more attributes? For example,
"CN=foo ,DC= ,DC=example,DC=com" -- since `d` has moved out of
bounds, won't we continue to use it and write more DN values into
mystery memory? Fortunately not, because the aforementioned allocation
of `l` bytes must happen first, and `l` is now huge. The allocation
happens in a talloc_memdup(), which is by default restricted to
allocating 256MB.
So this allows a person who controls a string parsed by ldb_dn_explode
to corrupt heap memory by placing a single zero byte at a chosen
offset before the allocated buffer.
An LDAP bind request can send a string DN as a username. This DN is
necessarily parsed before the password is checked, so an attacker does
not need proper credentials. The attacker can easily cause a denial of
service and we cannot rule out more subtle attacks.
The immediate solution is to reset `t` to NULL when a comma is
encountered, indicating that we are no longer looking at trailing
whitespace.

Change the API such that consumers can set the file descriptor to -1

If you want multiple handlers to consume the file descriptors, you

Use F_GETLK to get the lock holder PID, this is more accurate than

A wildcard search is divided into chunks by the asterisks. While most
chunks match the first suitable string, the last chunk matches the
last possible string (unless there is a trailing asterisk, in which
case this distinction is moot).
We always knew this in our hearts, but we tried to do it in a funny
complicated way that stepped through the string, comparing here and
there, leading to CVE-2019-3824 and missed matches (bug 14044).
With this patch, we just jump to the end of the string and compare it.
As well as being correct, this should also improve performance, as the
previous algorithm involved a quadratic loop of erroneous memmem()s.

When samba runs as ADDC only the main 'samba' daemon have to notify

This commit adds a function to disable the systemd notification in the
