Arch Linux

Description:
The installation path for libvirt_leaseshelper was changed in version 6.8.0.1

Previously:
$ bsdtar -tf /var/cache/pacman/pkg/libvirt-6.5.0-2-x86_64.pkg.tar.zst | grep lease
usr/lib/libvirt/libvirt_leaseshelper

Now:
$ bsdtar -tf /var/cache/pacman/pkg/libvirt-6.8.0-1-x86_64.pkg.tar.zst | grep lease
usr/lib/libvirt_leaseshelper

But the AppArmor profile for dnsmasq (/etc/apparmor.d/usr.sbin.dnsmasq) refers to /usr/lib/libvirt/libvirt_leaseshelper.
Consequently, the following error message may be observed at network startup:

libvirtd[2473]: internal error: Child process (VIR_BRIDGE_NAME=virbr0
/usr/bin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/default.conf --leasefile-ro --dhcp-scrip
t=/usr/lib/libvirt_leaseshelper) unexpected exit status 3: sh: /usr/lib/libvirt_leaseshelper:
Permission denied
dnsmasq: cannot run lease-init script /usr/lib/libvirt
_leaseshelper: Permission denied


Here is a workaround:
/etc/apparmor.d/usr.sbin.dnsmasq
89c89
< /usr/lib{,64}/libvirt/libvirt_leaseshelper Cx -> libvirt_leaseshelper,
---
> /usr/lib{,64}/{libvirt/,}libvirt_leaseshelper Cx -> libvirt_leaseshelper,

< /usr/lib{,64}/libvirt/libvirt_leaseshelper m,
