isc-dhcp (4.4.1-2.1ubuntu5.20.04.5) focal; urgency=medium

  [ Mauricio Faria de Oliveira ]
  * Prevent race condition that might ignore DHCP OFFERs/ACKs
    when dhclient receives DHCP traffic noise. (LP: #1926139)
    The previous/racy behavior can be switched back on with
    the 'DHCP_FD_FLAGS_POKE=0' environment variable or
    the 'dhcp.fd_flags_poke=0' kernel cmdline option.
    - d/p/lp1926139-watch-socket-fd-later.patch: fix, switches.
    - d/apparmor/sbin.dhclient,usr.sbin.dhcpd: /proc/cmdline r.

  [ Steve Langasek ]
  * Include /etc/dhcp/dhclient-exit-hooks.d/rfc3442-classless-routes
    in the initramfs. (LP: #1937110)
    - d/initramfs-tools/share/hooks/zz-dhclient: copy_exec it.
