This fixes a race condition that leads to the winbindd_children list becoming
corrupted. It happens when on a busy winbind SIGCHLD is a bit late.
Imagine a winbind with multiple requests in the queue for a single child. Child
dies, and before the SIGCHLD handler is called we find the socket to be dead.
wb_child_request_done is called, receiving an error from wb_simple_trans_recv.
It closes the socket. Then immediately the wb_child_request_trigger will do
another fork_domain_child before the signal handler is called. This means that
we do another fork_domain_child, we have child->sock==-1 at this point.
fork_domain_child will do a DLIST_ADD(winbindd_children, child) a second time
where the child is already part of that list. This corrupts the list. Then the
signal handler kicks in, spinning in
for (child = winbindd_children; child != NULL; child = child->next) {
forever. Not good. This patch makes sure that both conditions (sock==-1 and not
part of the list) for a winbindd_child struct match up.

This will help projects like OpenChange that depend on
this code, now that it has been split between two libraries.

This string is reported to the caller, which makes debugging much easier.

Counterpart for last checkin. A lot less likely, but not impossible in a child.

I've seen

fork_domain_child: Could not read child status: nread=-1, error=Interrupted system call
on a customer box. Not good.

Samba3 python module using passdb api modifies the database files, to
upgrade them to latest version. So copy the sample database before
running tests on it.

To correctly find the domain sid, passdb api uses netbios name to
look up secrets database. If no nebios name is configured, passdb uses
current hostname and adds entry for hostname in secrets and uses that
instead of the intended one.

upgrade_from_s3 script now requires samba3 configuration file and target
directory for samba4 database. In addition, it either uses --libdir option
or --testparm option to correctly guess the paths for samba3 databases
(private dir and state directory).
Usage: upgrade_from_s3 [options] <configuration_file> <targetdir>
Input arguments are:
<configuration_file> - path to existing smb.conf
<targetdir> - directory in which samba4 database will be created
In addition, specify either samba3 database directory (with --libdir) or
samba3 testparm utility (with --testparm).
Before using passdb interface, initialize s3 loadparm context using
correct path settings for private dir and state directory.
Export account policy from s3 to s4.

Instead of parsing samba3 database files (password, group mapping,
account policy, secrets), use passdb python wrapper.
Similarly for parsing configuration, use samba3 param python wrapper.
Other databases (idmap, registry, wins) are still parsed in python.

This also fixes the earlier faulty handing in of a useless stackframe
memory context via private_data.
|
|
This also fixes broken private_data parameter for the traverse function
(making use of it): Originally a memory context was handed in but was not used.
