When running multiple instances of dnsmasq, for example one being for the lan

configured in both networks

Currently, when using multiple dnsmasq instances they are all assigned
to the same Ubus instance name. This does not work, as only a single
instance can register with Ubus at a time. In the log, this leads to
`Cannot add object to UBus: Invalid argument` error messages.
Furthermore, upstream 3c93e8eb41952a9c91699386132d6fe83050e9be changes
behaviour so that instead of the log, dnsmasq exits at start instead.
With this patch, all dnsmasq instances are assigned unique names so that
they can register with Ubus concurrently. One of the enabled instances
is always assigned the previous default name "dnsmasq" to avoid breaking
backwards compatibility with other software relying on that default.
Previously, a random instance got assigned that name (while the others
produced error logs). Now, the first unnamed dnsmasq config section is
assigned the default name. If there are no unnamed dnsmasq sections the
first encountered named dnsmasq config section is assigned instead.
A similar issue exists for Dbus and was similarly addressed.

In the aftermath of the KRACK attacks, hostapd gained an AP-side workaround
against WNM-Sleep Mode GTK/IGTK reinstallation attacks. WNM Sleep Mode is not
enabled by default on OpenWrt, but it is configurable through the option
wnm_sleep_mode. Thus, make the AP-side workaround configurable as well by
exposing the option wnm_sleep_mode_no_keys. If you use the option
wpa_disable_eapol_key_retries and have wnm_sleep_mode enabled, you might
consider using this workaround.

Commit 0a7657c ("hostapd: add channel utilization as config option") added the
two new uci options bss_load_update_period and chan_util_avg_period. However,
the corresponding "config_add_int" calls for these options weren't added, so
attempting to actually use these options and change their values is bound to
fail - they always stay at their defaults. Add the missing code to actually
make these options work.

If the environment variable FILTER is set before compilation,
compilation of the ppp-package will fail with the error message
Package ppp is missing dependencies for the following libraries:
libpcap.so.1
The reason is that the OpenWrt-patch for the Makefile only comments
out the line FILTER=y. Hence the pcap-library will be dynamically
linked if the environment variable FILTER is set elsewhere, which
causes compilation to fail. The fix consists on explicitly unsetting
the variable FILTER instead.

p2p_add_device() may remove the oldest entry if there is no room in the
peer table for a new peer. This would result in any pointer to that
removed entry becoming stale. A corner case with an invalid PD Request
frame could result in such a case ending up using (read+write) freed
memory. This could only by triggered when the peer table has reached its
maximum size and the PD Request frame is received from the P2P Device
Address of the oldest remaining entry and the frame has incorrect P2P
Device Address in the payload.
Fix this by fetching the dev pointer again after having called
p2p_add_device() so that the stale pointer cannot be used.
This fixes the following security vulnerabilities/bugs:
- CVE-2021-27803 - A vulnerability was discovered in how p2p/p2p_pd.c
in wpa_supplicant before 2.10 processes P2P (Wi-Fi Direct) provision
discovery requests. It could result in denial of service or other
impact (potentially execution of arbitrary code), for an attacker
within radio range.

This is a backport of the upstream commit 58bbbb598144 ("nl80211: Ignore
4addr mode enabling error if it was already enabled") which fixes same
issue as in the current fix contained in '130-wpa_supplicant-multi_ap_roam.patch',
but in a different way:
nl80211_set_4addr_mode() could fail when trying to enable 4addr mode on
an interface that is in a bridge and has 4addr mode already enabled.
This operation would not have been necessary in the first place and this
failure results in disconnecting, e.g., when roaming from one backhaul
BSS to another BSS with Multi AP.
Avoid this issue by ignoring the nl80211 command failure in the case
where 4addr mode is being enabled while it has already been enabled.
