Re: [libvirt] [PATCH] qemu: fix up permissions for pre-created UNIX sockets

My commit d6b8838 fixed the uid:gid for the pre-created UNIX sockets but did not account for the different umask of libvirtd and QEMU. Since commit 0e1a1a8c we set umask to '0002' for the QEMU process. Manually tune-up the permissions to match what we would have gotten if QEMU had created the socket. https://bugzilla.redhat.com/show_bug.cgi?id=1633389 Signed-off-by: Ján Tomko <jtomko(a)redhat.com&gt; --- src/qemu/qemu_command.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index 887947dc11..d77cf8c2d6 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -5034,6 +5034,12 @@ qemuOpenChrChardevUNIXSocket(const virDomainChrSourceDef *dev) goto error; } + /* We run QEMU with umask 0002.
