This reverts commit 266f97b5e9, reversing
changes made to a10253cffe.
A mismerge of a merge to catch up to main resulted in files being
committed which should not have been.
Yan Zhong at FreeBSD Foundation is working on a wireless network
configuratior for an experimental FreeBSD installer. The new installer
requires an event to detect when connecting to a network fails due to a
bad password. When this happens a WPA-EVENT-TEMP-DISABLED event is
triggered. This patch passes the event to an action file provided by
the new experimental installer.

Remove files added by b51f459a20.
The util/config.c conflicts with wpa_supplicant/config.c causing
the linker error.
The proper approach would have been to prepare the wpa build to
build the various subdirectories into .a libraries. SRCS makes no
distinction between files of the same name. The MFV accounted for this
but the revert failed to remove the additional files, including the
conflicting utils/config.c.
b51f459a20 resulted in a mismerge
due to having to do a remerge because my tree was over a week out of
date. Changes that were made to fix the build were lost in the remerge
resulting in build errors that were fixed a week ago.
This is the April update to vendor/wpa committed upstream
2021/04/07.
This is MFV efec822389.

Vulnerability
A vulnerability was discovered in how wpa_supplicant processes P2P
(Wi-Fi Direct) provision discovery requests. Under a corner case
condition, an invalid Provision Discovery Request frame could end up
reaching a state where the oldest peer entry needs to be removed. With
a suitably constructed invalid frame, this could result in use
(read+write) of freed memory. This can result in an attacker within
radio range of the device running P2P discovery being able to cause
unexpected behavior, including termination of the wpa_supplicant process
and potentially code execution.
Vulnerable versions/configurations
wpa_supplicant v1.0-v2.9 with CONFIG_P2P build option enabled
An attacker (or a system controlled by the attacker) needs to be within
radio range of the vulnerable system to send a set of suitably
constructed management frames that trigger the corner case to be reached
in the management of the P2P peer table.
Note: FreeBSD base does not enable P2P.
bfc99943b0 removed ndis(4) support however

determine the length of the routing table buffer. As of 81728a538d
wpa_supplicant is started before the routing table has been populated
resulting in the length of zero to be returned. This causes
wpa_supplicant to loop endlessly. (The workaround is to kill and restart
wpa_supplicant as by the time it is restarted the routing table is
populated.)
(Personally, I was not able to reproduce this unless wlan0 was a member of
lagg0. However, others experienced this problem on standalone wlan0.)

Upstream commit message:
[PATCH 3/3] WPS UPnP: Handle HTTP initiation failures for events more
properly
While it is appropriate to try to retransmit the event to another
callback URL on a failure to initiate the HTTP client connection, there
is no point in trying the exact same operation multiple times in a row.
Replve the event_retry() calls with event_addr_failure() for these cases
to avoid busy loops trying to repeat the same failing operation.
These potential busy loops would go through eloop callbacks, so the
process is not completely stuck on handling them, but unnecessary CPU
would be used to process the continues retries that will keep failing
for the same reason.

Upstream commit message:
[PATCH 2/3] WPS UPnP: Fix event message generation using a long URL path
More than about 700 character URL ended up overflowing the wpabuf used
for building the event notification and this resulted in the wpabuf
buffer overflow checks terminating the hostapd process. Fix this by
allocating the buffer to be large enough to contain the full URL path.
However, since that around 700 character limit has been the practical
limit for more than ten years, start explicitly enforcing that as the
limit or the callback URLs since any longer ones had not worked before
and there is no need to enable them now either.

[PATCH 1/3] WPS UPnP: Do not allow event subscriptions with URLs to
other networks
The UPnP Device Architecture 2.0 specification errata ("UDA errata
16-04-2020.docx") addresses a problem with notifications being allowed
to go out to other domains by disallowing such cases. Do such filtering
for the notification callback URLs to avoid undesired connections to
external networks based on subscriptions that any device in the local
network could request when WPS support for external registrars is
enabled (the upnp_iface parameter in hostapd configuration).

WPA: Ignore unauthenticated encrypted EAPOL-Key data
Ignore unauthenticated encrypted EAPOL-Key data in supplicant
processing. When using WPA2, these are frames that have the Encrypted
flag set, but not the MIC flag.
When using WPA2, EAPOL-Key frames that had the Encrypted flag set but
not the MIC flag, had their data field decrypted without first verifying
the MIC. In case the data field was encrypted using RC4 (i.e., when
negotiating TKIP as the pairwise cipher), this meant that
unauthenticated but decrypted data would then be processed. An adversary
could abuse this as a decryption oracle to recover sensitive information
in the data field of EAPOL-Key messages (e.g., the group key).

After configuring the interface, wait for the link to become active.
Many ethernet drivers reset the chip when we set multicast filters
(causing significant delays due to link re-negotiation) and, by the time
we start sending packets, they are discared instead of going to the ether.
