DirSourceAddress option causes "Error: bsockcore.c:400 Source address bind error. proto=2. ERR=Invalid argument"

Summary

Description

The director option DirSourceAddress causes errors to be logged during the backup:

27-Jan 14:12 XXXX-fd JobId 92959: Error: bsockcore.c:400 Source address bind error. proto=2. ERR=Invalid argument

Backups complete with "OK -- with warnings", but strace shows that bacula-dir tries to bind an AF_INET6 socket to an IPv4 address (regardless of whether DirSourceAddress is IPv4 or IPv6).

Steps to Reproduce

Create Ubuntu 24.04 container or VM for director. apt-get install bacula-server bacula-console
Configure as below. Test with "run BackupCatalog" at bconsole. Check that it ends with "Termination: Backup OK"
Add to the Director{} block: DirSourceAddress = 10.65.5.21, where this is the external IP of the container or VM
- (127.0.0.1 can also be used to demonstrate the problem, but the strace is clearer with a real IP address)
systemctl restart bacula-director. Optional: strace -f -s 256 -p $(pidof bacula-dir) 2>/var/tmp/bacula.strace
Re-run the BackupCatalog job

The following is logged:

27-Jan 16:23 director-dir JobId 7: shell command: run BeforeJob "/etc/bacula/scripts/make_catalog_backup.pl MyCatalog"

It has twice created an AF_INET6 socket, but tried to bind an IPv4 address to it!

Next, repeat this experiment with DirSourceAddress = fd42:81e:c751:8c26:216:3eff:fe39:87e7 (the IPv6 address of the container, and again you can use ::1 if you prefer). This time you get the same Source address bind error, with the following strace:

This time it has correctly opened an AF_INET6 socket, but it tries to bind the IPv4 address 0.0.0.0, instead of the IPv6 address given.

I believe the correct behaviour should be:

If DirSourceAddress is IPv4, then open an AF_INET socket (not AF_INET6) and bind it to the given IPv4 address
If DirSourceAddress is IPv6, then open an AF_INET6 socket and bind it to the given IPv6 address (not 0.0.0.0)

It looks like a mixup of address families.

Additional Information

Aside: the reason I want to use this option is to force a Bacula director running on a dual-stack host to originate outbound connections to remote bacula-fd over IPv4, by binding outgoing connections to the local IPv4 network address.

director setup:

mkdir -p /backup/bacula /backup/restore
chown -R bacula:bacula /backup
