* passt: Relicense to GPL 2.0, or any later versionStefano Brivio2023-04-061-1/+1
| | | | | | | | | | | | | | | | | | | In practical terms, passt doesn't benefit from the additional protection offered by the AGPL over the GPL, because it's not suitable to be executed over a computer network. Further, restricting the distribution under the version 3 of the GPL wouldn't provide any practical advantage either, as long as the passt codebase is concerned, and might cause unnecessary compatibility dilemmas. Change licensing terms to the GNU General Public License Version 2, or any later version, with written permission from all current and past contributors, namely: myself, David Gibson, Laine Stump, Andrea Bolognani, Paul Holzinger, Richard W.M. Jones, Chris Kuhn, Florian Weimer, Giuseppe Scrivano, Stefan Hajnoczi, and Vasiliy Ulyanov. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>

* contrib/selinux: Allow binding and connecting to all UDP and TCP portsStefano Brivio2023-03-091-12/+15
| | | | | | | | | | | | | | | | | | | | | Laine reports that with a simple: <portForward proto='tcp'> <range start='2022' to='22'/> </portForward> in libvirt's domain XML, passt won't start as it fails to bind arbitrary ports. That was actually the intention behind passt_port_t: the user or system administrator should have explicitly configured allowed ports on a given machine. But it's probably not realistic, so just allow any port to be bound and forwarded. Also fix up some missing operations on sockets.

* contrib/selinux: Let passt write to stdout and stderr when it startsStefano Brivio2023-03-091-0/+1
| | | | | | | | | | Otherwise, it's unusable as stand-alone tool, or in foreground mode, and it's also impossible to get output from --help or --version, because for SELinux it's just a daemon.

* selinux: Switch to a more reasonable model for PID and socket filesStefano Brivio2023-02-211-4/+7
| | | | | | | | Instead of restricting PID files to /var/run/passt.pid, which is a single file and unlikely to be used, use the user_tmp_t type which should cover any reasonable need. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
* selinux: Define interfaces for libvirt and similar frameworksStefano Brivio2023-02-211-0/+1
| | | | | | | | | | Services running passt will commonly need to transition to its domain, terminate it, connect and write to its socket. The init_daemon_domain() macro now defines the default transition to the passt_t domain, using the passt_exec_t type. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
