Subject: [Qemu-devel] [PATCH 0/2] fix: unix sockets created for virtio-serail has insufficient permissions
Date: Tue,  2 Sep 2014 15:40:41 +0800	[thread overview]
Message-ID: <1409643643-31589-1-git-send-email-cyliu@suse.com> (raw)

https://sourceware.org/bugzilla/show_bug.cgi?id=13078#c11
https://bugzilla.novell.com/show_bug.cgi?id=888166

To use virtio-serial device, unix socket created for chardev with
default umask(022) has insufficient permissions.
e.g.:
-device virtio-serial \
-chardev socket,path=/tmp/foo,server,nowait,id=foo \
-device virtserialport,chardev=foo,name=org.fedoraproject.port.0

#ls -l /tmp/somefile.sock
srwxr-xr-x 1 qemu qemu 0 21. Jul 14:19 /tmp/somefile.sock

Other users in the same group (like real user, test engines, etc)
cannot write to this socket.

These patch series contains a qemu patch and a libvirt patch:
qemu patch: adds a new 'umask' option to -chardev, so that user can
    change the umask.
libvirt patch: pass 'umask=0x002' paramter to qemu command line
    for virtio-serial device

Chunyan Liu (2):
  qemu side: add 'umask' option to chardev
  libvirt side: qemu: add umask(002) to virtio-serial chardev commandline
