Jouni Malinen 8540e0b520 hostapd: Fix DETACH command debug prints to avoid use of freed memory
In case a control interface socket is detached because of sendmsg()
failing for the socket, function call to detach the socket uses a
pointer to the socket information in the structure to be freed. Reorder
code to print socket info before freeing the data to avoid use of freed
memory in case debug prints are enabled.

This is similar to the earlier wpa_supplicant fix in commit
a235aca316.

Jouni Malinen 2b6623ab13 hostapd: Do not terminate process on dynamic interface add failure
Limit the calls to eloop_terminate() to happen only for the
initialization failure from the interfaces that we specified on the
command line. This allows hostapd process to continue operating even if
a dynamically added interface fails to start up. This allows the upper
layer software to fix a configuration error and retry.

Jouni Malinen 2fe210cebb hostapd: Fix multi-BSS configuration file parsing regression
Commit ebd79f07c4 broke parsing of
configuration files that use the bss parameter to specify another BSS
entry. This resulted in crashing the process with NULL pointer
dereference since the new hostapd_config::bss design requires this
function to allocate a new hostapd_bss_config structure.

Jouni Malinen 5afaa067d9 hostapd: Allow per-BSS (vif) configuration files
This provides a new option for configuring multiple virtual interfaces
(BSS) that share a single radio. The new command line parameter
-b<phyname>:<config file name> is used to define one or more virtual
interfaces for each PHY. The first such entry for a new PHY is used to
initialize the interface structure and all consecutive parameters that
have the same PHY name will be added as virtual BSS entries to that
interface. The radio parameters in the configuration files have to be
identical.

This can be used as an alternative for the bss=<ifname> separator and
multiple BSSes in a single configuration file design while still
allowing hostapd to control the PHY (struct hostapd_iface) as a group of
virtual interfaces (struct hostapd_data) so that common radio operations
like OLBC detection and HT40 co-ex scans can be done only once per real
radio.

This option can be used in a WDS setup where one AP acts as a

Jouni Malinen 080585c01a Add support for OCSP stapling to validate server certificate
When using OpenSSL with TLS-based EAP methods, wpa_supplicant can now be
configured to use OCSP stapling (TLS certificate status request) with
ocsp=1 network block parameter. ocsp=2 can be used to require valid OCSP
response before connection is allowed to continue.

hostapd as EAP server can be configured to return cached OCSP response
using the new ocsp_stapling_response parameter and an external mechanism
for updating the response data (e.g., "openssl ocsp ..." command).

This allows wpa_supplicant to verify that the server certificate has not
been revoked as part of the EAP-TLS/PEAP/TTLS/FAST handshake before
actual data connection has been established (i.e., when a CRL could not
be fetched even if a distribution point were specified).
