a07b8a70b5 mka: New MI should only be generated when peer's key is invalid
Two recent changes to MKA create a situation where a new MI is generated
every time a SAK Use parameter set is decoded.  The first change moved
invalid key detection from ieee802_1x_decode_basic_body() to
ieee802_1x_kay_decode_mpkdu():

  commit db9ca18bbf ("mka: Do not ignore MKPDU parameter set decoding failures")

The second change forces the KaY to generate a new MI when an invalid
key is detected:

  commit a8aeaf41df ("mka: Change MI if key invalid")

The fix is to move generation of a new MI from the old invalid key
detection location to the new location.

10de40c0c8 DFS: Restart pending CAC on interface enable
When an interface is re-enabled after it was disabled during CAC, it
won't ever get active since hostapd is waiting for a CAC_FINISHED while
kernel side is waiting for a CMD_RADAR_DETECT to start a CAC.

This commit checks for a pending CAC when an interface is enabled and if
so restarts its DFS processing.

27ebadccfb RADIUS client: Cease endless retry for message for multiple servers
In the previous RADIUS client implementation, when there are multiple
RADIUS servers, we kept trying the next server when the current message
can not be acked. It leads to endless retry when all the RADIUS servers
are down.

Fix this by keeping a counter for the accumulated retransmit attempts
for the message, and guarantee that after all the servers failover
RADIUS_CLIENT_MAX_FAILOVER times the message will be dropped.

Another issue with the previous code was that the decision regarding
whether the server should fail over was made immediately after we send
out the message. This patch guarantees we consider whether a server
needs failover after pending ack times out.

89d79150ac Avoid forward references to enum types in ieee802_11_common.h
These are not allowed in ISO C++ (and well, not really in ISO C either,
but that does not result in compiler warning without pedantic
compilation).

Since ieee802_11_common.h may end up getting pulled into C++ code for
some external interfaces, it is more convenient to keep it free of these
cases. Pull in ieee802_11_defs.h to get enum phy_type defined and move
enum chan_width to common/defs.h (which was already pulled in into
src/drivers/driver.h and src/common/ieee802_11_common.h).

bb35e2d214 hostapd: Work around an interop connection issue in FT-PSK + WPA-PSK
While the AP is configured to enable both FT-PSK and WPA-PSK, an HP
printer request both AKMs (copied from AP?) in Association Request
frame, but don't add MDIE and don't use FT. This results in the
connection failing.

Next in logs we see:

RSN: Trying to use FT, but MDIE not included
IE - hexdump(len=26): 30 18 01 00 00 0f ac 04 01 00 00 0f ac 04

This is seen with some HP and Epson printers. Work around this by
stripping FT AKM(s) when MDE is not present and there is still a non-FT
AKM available.

02f52ab6f5 Use lchown() instead of chown() for self-created files
There is no need to allow symlink dereferencing in these cases where a
file (including directories and sockets) are created by the same
process, so use the safer lchown() variant to avoid leaving potential
windows for something external to replace the file before the chown()
call. The particular locations used here should not have write
permissions enabled for processes with less privileges, so this may not
be needed, but anyway, it is better to make these more restrictive
should there be cases where directory permissions are not as expected
for a good deployment.

b686745c76 Android: Harden wpa_ctrl_open2() against potential race conditions
The Android-specific chmod and chown operations on the client socket
(for communication with wpa_supplicant) did not protect against file
replacement between the bind() and chmod()/chown() calls. If the
directory in which the client socket is created (depends a bit on the
version and platform, but /data/misc/wifi/sockets is commonly used)
allows write access to processes that are different (less privileged)
compared to the process calling wpa_ctrl_open2(), it might be possible
to delete the socket file and replace it with something else (mainly, a
symlink) before the chmod/chown operations occur. This could have
resulted in the owner or permissions of the target of that symlink being
modified.

In general, it would be safest to use a directory which has more limited
write privileges (/data/misc/wifi/sockets normally has 'wifi' group
(AID_WIFI) with write access), but if that cannot be easily changed due
to other constraints, it is better to make wpa_ctrl_open2() less likely
to enable this type of race condition between the operations.

Replace chown() with lchown() (i.e., a version that does not dereference
symlinks) and chmod() with fchmod() on the socket before the bind() call
which is also not going to dereference a symlink (whereas chmod()
would). lchown() is a standard operation, but the fchmod() on the socket
is less so (unspecified behavior in some systems). However, it seems to
work on Linux and in particular, on Android, where this code is
executed.

cc9c4feccc OpenSSL: Allow systemwide policies to be overridden
Some distributions (e.g., Debian) have started introducting systemwide
OpenSSL policies to disable older protocol versions and ciphers
throughout all programs using OpenSSL. This can result in significant
number of interoperability issues with deployed EAP implementations.

Allow explicit wpa_supplicant (EAP peer) and hostapd (EAP server)
parameters to be used to request systemwide policies to be overridden if
older versions are needed to be able to interoperate with devices that
cannot be updated to support the newer protocol versions or keys. The
default behavior is not changed here, i.e., the systemwide policies will
be followed if no explicit override configuration is used. The overrides
should be used only if really needed since they can result in reduced
security.

In wpa_supplicant, tls_disable_tlsv1_?=0 value in the phase1 network
profile parameter can be used to explicitly enable TLS versions that are
disabled in the systemwide configuration. For example,
phase1="tls_disable_tlsv1_0=0 tls_disable_tlsv1_1=0" would request TLS
v1.0 and TLS v1.1 to be enabled even if the systemwide policy enforces
TLS v1.2 as the minimum version. Similarly, openssl_ciphers parameter
can be used to override systemwide policy, e.g., with
openssl_ciphers="DEFAULT@SECLEVEL=1" to drop from security level 2 to 1
in Debian to allow shorter keys to be used.

In hostapd, tls_flags parameter can be used to configure similar
options. E.g., tls_flags=[ENABLE-TLSv1.0][ENABLE-TLSv1.1]

was added to the driver, so key reinstallation is not a concern for this
