Hirokazu MORIKAWA 779af4d40c avahi: Import patches for security fixes 
Imported patches included in debian and other package.

* 200-Fix-NULL-pointer-crashes-from-175.patch
  CVE-2021-3502
   A flaw was found in avahi 0.8-5. A reachable assertion is present in avahi_s_host_name_resolver_start function allowing a local attacker to crash the avahi service by requesting hostname resolutions through the avahi socket or dbus methods for invalid hostnames. The highest threat from this vulnerability is to the service availability.

* 201-Avoid-infinite-loop-in-avahi-daemon-by-handling-HUP-event.patch
  CVE-2021-3468
   A flaw was found in avahi in versions 0.6 up to 0.8. The event used to signal the termination of the client connection on the avahi Unix socket is not correctly handled in the client_work function, allowing a local attacker to trigger an infinite loop. The highest threat from this vulnerability is to the availability of the avahi service, which becomes unresponsive after this flaw is triggered.

* 202-avahi_dns_packet_consume_uint32-fix-potential-undefined-b.patch
   avahi_dns_packet_consume_uint32 left shifts uint8_t values by 8, 16 and 24 bits to combine them into a 32-bit value. This produces an undefined behavior warning with gcc -fsanitize when fed input values of 128 or 255 however in testing no actual unexpected behavior occurs in practice and the 32-bit uint32_t is always correctly produced as the final value is immediately stored into a uint32_t and the compiler appears to handle this "correctly".
Cast the intermediate values to uint32_t to prevent this warning and ensure the intended result is explicit.

* 203-Do-not-disable-timeout-cleanup-on-watch-cleanup.patch
   This was causing timeouts to never be removed from the linked list that tracks them, resulting in both memory and CPU usage to grow larger over time.

* 204-Emit-error-if-requested-service-is-not-found.patch
   It currently just crashes instead of replying with error. Check return
value and emit error instead of passing NULL pointer to reply.

* 205-conf-file-line-lengths.patch
   Allow avahi-daemon.conf file to have lines longer than 256 characters (new limit 1024).

endef
define Package/avahi/Default/description
Avahi is an mDNS/DNS-SD (aka RendezVous/Bonjour/ZeroConf)
implementation (library). It facilitates
service discovery on a local network -- this means that
you can plug your laptop or computer into a network and
instantly be able to view other people who you can chat with,
find printers to print to or find files being shared.
This kind of technology is already found in MacOS X
(branded 'Rendezvous', 'Bonjour' and sometimes 'ZeroConf')
and is very convenient.

endef
define Package/avahi-autoipd/description
$(call Package/avahi/Default/description)
.
This package implements IPv4LL, "Dynamic Configuration of IPv4 Link-Local
Addresses" (IETF RFC3927), a protocol for automatic IP address configuration
from the link-local 169.254.0.0/16 range without the need for a central
server. It is primarily intended to be used in ad-hoc networks which lack a
DHCP server.
