e234c7c010 OpenSSL: Remove md4_vector() from CONFIG_FIPS=y builds
MD4 is not allowed in such builds, so comment out md4_vector() from the
build to force compile time failures for cases that cannot be supported
instead of failing the MD¤ operations at runtime. This makes it easier
to detect and fix accidental cases where MD4 could still be used in some
older protocols.

Commit 94f1fe6f63 ('Remove master key

3b86d77bae P2P: Silence bogus compiler warnings
It looks like the compiler version used in Android 5.0 warns about
potentially uninitialized oper_freq variable in these debug messages.
That is not really valid since this code path can be reached only if
found != 0 and in such a case, oper_freq is set. Anyway, it seems better
to avoid compiler warnings, so add an unnecessary initialization for
oper_freq for now.

276a3c44dd OpenSSL: Implement aes_wrap/aes_unwrap through EVP for CONFIG_FIPS=y
The OpenSSL internal AES_wrap_key() and AES_unwrap_key() functions are
unfortunately not available in FIPS mode. Trying to use them results in
"aes_misc.c(83): OpenSSL internal error, assertion failed: Low level API
call to cipher AES forbidden in FIPS mode!" and process termination.
Work around this by reverting commit
f19c907822 ('OpenSSL: Implement aes_wrap()
and aes_unwrap()') changes for CONFIG_FIPS=y case. In practice, this
ends up using the internal AES key wrap/unwrap implementation through
the OpenSSL EVP API which is available in FIPS mode. When CONFIG_FIPS=y
is not used, the OpenSSL AES_wrap_key()/AES_unwrap_key() API continues
to be used to minimize code size.

6cc364946c P2P: Process preferred frequency list as part of GO Neg Req/Resp
When processing a GO Negotiation Request and Response, if local driver
supports the preferred channel list extension, then:

- Check if peer's preference for operating channel is already included
  in our preferred channel list and if so, take the oper_channel as is.

- If peer's preference for operating channel is not in local device's
  preferred channel list and peer device has provided its preferred
  frequency list in the GO Negotiation Request/Response, then find a
  channel that is common for both preferred channel lists and use it
  for oper_channel.

- If peer's preference for operating channel is not in local device's
  preferred channel list and peer device doesn't use preferred channel
  list extension, i.e., no preferred channel list in GO Negotiation
  Request/Response, then look for a channel that is common for local
  device's preferred channel list and peer's list of supported channels
  and use it for oper_channel.

- In case no common channel is found, use the peer's preference for
  oper_channel as is.

0ef54bd30e P2P: Do not omit known operating channel preference from GO Neg Resp
Add an extra condition to omit operating channel preference when
building GO Negotiation Response. If the local device supports the
preferred frequency list extension, then when sending a GO Negotiation
Response frame, advertise the preferred operating channel unless local
device is assuming the P2P Client role and has an empty preferred
frequency list, in which case local device can omit its preference for
the operating channel.

This change helps make use of the preferred frequency list and the
calculated best channel for both negotiating parties of the P2P
connection.

34c5267bbc Return error from wpa_drv_get_pref_freq_list() if no driver support
Commit 983422088f ('nl80211: Add means to
query preferred channels') return success if no driver wrapper callback
was provided for fetching the preferred channel list. That is
problematic since the *num argument is not updated and uninitialized
freq_list could end up getting used with arbitrary frequency values. Fix
this by returning error in case the values were not available due to
driver wrapper not implementing the function. This matches the style
used in the driver_nl80211.c implementation for the case where the
driver does not support such fetch operation.
