a4e73a0e47 Fix potential double free and use of freed memory in RADIUS client
ieee802_1x_encapsulate_radius() frees the RADIUS message if
radius_client_send() returns error. This could have resulted in use of
freed memory and double freeing of the RADIUS message if send() fails
since the message is also left in the retransmit list. Avoid this by not
returning error to the caller in such a case.

e3e52e364e hostapd: Fix RADIUS client configuration update on reconfig
The internal pointer to RADIUS client configuration needs to be
updated whenever a new hostapd configuration is loaded. Without
this, freed memory may be dereferenced and this can result in
segmentation faults.

1489e11a94 Make struct radius_msg private to radius.c
This is internal data structure for RADIUS message handling and
external code should not touch it directly.

9e7245bdb4 Change radius_msg_free() to free the buffer
Since all callers were freeing the buffer immediately anyway, move
this operation into radius_msg_free() to reduce code size.

93704f8f95 Remove unused RADIUS client reconfig function
This is not actually used at all and it looks like the rules for
maintaining the old/new RADIUS configuration are not very clear in the
case the RADIUS client configuration did not change. Consequently, it
is better to just remove this for now and if similar functionality is
ever needed, redesign it to be easier to use without causing hard to
find issues with using freed memory.

Simpler approach to reconfiguring the RADIUS client would involve
just deinitializing the old context unconditionally and initializing
a new one whenever the configuration could have changed.

a2fbf12524 Disable PMTU discovery for RADIUS packets (sent them without DF)
When Linux has Path MTU discovery enabled, it sets by default the DF bit
on all outgoing datagrams, also UDP ones. If a RADIUS message is bigger
than the smallest MTU size to the target, it will be discarded.

This effectively limits RADIUS messages to ~ 1500 Bytes, while they can
be up to 4k according to RFC2865. In practice, this can mean trouble
when doing EAP-TLS with many RADIUS attributes besides the EAP-Message.

815c5e1435 Fixed RADIUS client local address forcing for IPv6 (eapol_test)

c454f57379 eapol_test: Allow client IP address to be specified
Allow the user to set the IP address of the eapol_test client. This if
very useful when you have a machine with many interfaces and want to use a
particular one for testing RADIUS connectivity. For instance when I run the
national eduroam proxy I can only connect to other server from a particular
address, an our machine happens to have several IPs. So if I want to run
connectivity tests, I must make sure that my test uses a particular
interface. The -A option allows one to set this).

(jm: cleaned up to use radius configuration structure instead of global
variable for the address and added IPv6 support)
