From 4fe08d31e4d168688bfa246929ebbcdf54f54352 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marek=20Marczykowski-G=C3=B3recki?= Date: Sat, 16 Feb 2019 14:56:14 +0100 Subject: [PATCH] Adjust permissions of /dev/xen/hypercall Starting with Linux 4.18, there is new device node for issuing hypercalls from user space - /dev/xen/hypercall (partially duplicating functionality of /dev/xen/privcmd). New Xen tools (4.12) make use of it, so make it available for them. Otherwise such tools will fail the operation (there is no fallback to privcmd on EACCESS). --- udev/udev-qubes-misc.rules | 1 + 1 file changed, 1 insertion(+) diff --git a/udev/udev-qubes-misc.rules b/udev/udev-qubes-misc.rules index 9c65c92..f5d17e7 100644 --- a/udev/udev-qubes-misc.rules +++ b/udev/udev-qubes-misc.rules @@ -4,3 +4,4 @@ KERNEL=="xen/gntdev", MODE="0660", GROUP="qubes" KERNEL=="xen/gntalloc", MODE="0660", GROUP="qubes" KERNEL=="xen/privcmd", MODE="0660", GROUP="qubes" KERNEL=="xen/xenbus", MODE="0660", GROUP="qubes" +KERNEL=="xen/hypercall", MODE="0660", GROUP="qubes"
