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.

(cherry picked from commit 1ca5de13a1)
This is a backport of the upstream commit 58bbbb598144 ("nl80211: Ignore
4addr mode enabling error if it was already enabled").
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.

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.

* rp-pppoe.so was renamed to pppoe.so

* 101-debian_close_dev_ppp.patch
* 103-debian_fix_link_pidfile.patch
* 106-debian_stripMSdomain.patch
* 107-debian_pppoatm_wildcard.patch
* 110-debian_defaultroute.patch

19aae94 [build: avoid rebuilds of unset VARIANT packages] builds
packages defined without a VARIANT only once, using the first VARIANT
defined in the Makefile.
This caused problems with wpa-cli, as it is only built for variants that
include supplicant support, and the first VARIANT defined may not build
it.
The same happens to hostapd-utils, which is not built for
supplicant-only variants.
To circumvent this, set VARIANT=* for both packages so that they get
built for every defined variant. This should not cause spurious
rebuilds, since tey are not a dependency of any other package defined in
this Makefile.

Package hostapd-common is a dependency of every other package defined in
hostpad Makefile. It is currently built next to the bottom of that
Makefile's package list.
If you run make back to back, then check-compile will compare the
hostapd-common timestamp to the variant being compiled, to decide if the
varint needs to be rebuilt or not. Since the hostapd-conf package is
built towards the end of the list, it will be newer than most of the
variants, causing unnecessary package rebuilds.
Move it to the top, so that its timestamp will be older than dependent
packages, avoiding unnecessary rebuild of every selected variant.

The existing wnm_disassoc_imminent ubus method only supports issuing a
bss transition request with the disassoc imminent flag set.
For use-cases, where the client is requested to roam to another BSS
without a pending disassoc, this existing method is not suitable.
Add a new bss_transition_request ubus method, which provides a more
universal way to dispatch a transition request. It takes the following
arguments:
Required:
addr: String - MAC-address of the STA to send the request to (colon-seperated)
Optional:
abridged - Bool - Indicates if the abridged flag is set
disassociation_imminent: Bool - Whether or not the disassoc_imminent
flag is set
disassociation_timer: I32 - number of TBTTs after which the client will
be disassociated
validity_period: I32 - number of TBTTs after which the beacon
candidate list (if included) will be invalid
neighbors: blob-array - Array of strings containing neighbor reports as
hex-string
