Here are a bunch of workarounds and a couple of fixes for libvirt
usage which are rather hard to split into single logical patches
as there appear to be some obscure dependencies between some of them:
- passt-repair needs to have an exec_type typeattribute (otherwise
the policy for lsmd(1) causes a violation on getattr on its
executable) file, and that typeattribute just happened to be there
for passt as a result of init_daemon_domain(), but passt-repair
isn't a daemon, so we need an explicit corecmd_executable_file()
- passt-repair needs a workaround, which I'll revisit once
https://github.com/fedora-selinux/selinux-policy/issues/2579 is
solved, for usage with libvirt: allow it to use qemu_var_run_t
and virt_var_run_t sockets
- add 'bpf' and 'dac_read_search' capabilities for passt-repair:
they are needed (for whatever reason I didn't investigate) to
actually receive socket files via SCM_RIGHTS
- passt needs further workarounds in the sense of
https://github.com/fedora-selinux/selinux-policy/issues/2579:
allow it to use map and use svirt_tmpfs_t (not just svirt_image_t):
it depends on where the libvirt guest image is
- ...it also needs to map /dev/null if <access mode='shared'/> is
enabled in libvirt's XML for the memoryBacking object, for
vhost-user operation
- and 'ioctl' on the TCP socket appears to be actually needed, on top
of 'getattr', to dump some socket parameters
