[Qemu-devel] [PATCH 1/2] slirp: don't use "smb ports = 0" option

Subject: [Qemu-devel] [PATCH 1/2] slirp: don't use "smb ports = 0" option

From: Nikolaus Rath <address@hidden>

The "smb ports = 0" option causes recent samba versions to crash. It was
introduced in commit 157777ef3e with log message "Samba 3 support".
However, a value of 0 has never been officially supported by smb and is
also not necessary: if stdin is a socket, smb does not try to listen on
any ports and uses just stdin. This is necessary to support inetd based
operation (otherwise smbd would always fail when called from inetd,
because inetd already listens on the SMB port). Since samba has
supported inetd operation since pre-3.x, it should be safe to rely on
this feature. I have tested it with Samba 3.6.4 -- communication works
fine, and smbd is not listening on any ports.

I suspect the "smb ports = 0" hack may have been introduced when someone
tested the qemu generated samba config from the command line with "smbd
-i" and found it to fail (because then stdin isn't a socket).
