eeb04821ad wpabuf: Add WPA_TRACE code to validate correct freeing of wpabuf
Use an extra header to move the returned pointer to break os_free()
or free() of the returned value and verify that the correct magic
is present when freeing or resizing the wpabuf. Show backtrace on
invalid wpabuf use.

fb4baa688b Add memory allocation analyzer to verify OS wrapper use
WPA_TRACE=y builds will now verify that memory allocation in done

mixing of os_* functions and unwrapper functions). In addition, some
common memory allocation issues (double-free, memory leaks, etc.) are
detected automatically.

f8b1f69561 Use generic driver events for TX status and RX reporting
Replace driver wrapper calls to hostapd_tx_status(),
hostapd_rx_from_unknown_sta(), hostapd_mgmt_rx(), and
hostapd_mgmt_tx_cb() with new generic driver events
EVENT_TX_STATUS, EVENT_RX_FROM_UNKNOWN, and EVENT_RX_MGMT.

This cleans up lot of the driver wrapper code to be less dependent
on whether it is being used within wpa_supplicant AP mode or hostapd.

50b5bf4eda Remove obsolete Prism54.org driver support (driver_prism54.c)
The Prism54.org project seems have been dead for a while and it does not
look like this driver would ever be maintained again. Furthermore, it is
difficult to find a version that would work with the driver_prism54.c
wrapper and there is another driver for these card in the Linux kernel
tree.

The hostapd integration in driver_prism54.c is quite different from the
other driver wrappers and would require major effort to get it cleaned
up. Since there does not seem to be any real users for the cleaned up
version, there does not seem to be justification to spend this effort on
the wrapper. This old code is making it much more difficult to clean up
the driver interface and at this point, the best option seems to be to
remove the driver wrappers. Should someone really still need this, the
old code will continue to be available in hostapd 0.6.x.

7e683ceeb4 WPS: Handle Selected Registrar as a union of info from all Registrars
Instead of using the latest selected registrar change, collect selected
registrar information separately from all registrars and use the union
of this information when building the WPS IE for Beacon and Probe
Response frames.

Note: SetSelectedRegistrar UPnP action does not include a unique
identifier, so the ER matching routine is based only on the IP address
of the ER. In theory, there could be multiple ERs using the same IP
address (but different port or URL), so there may be some corner cases
that would not always match the correct ER entry at the AP. Anyway, this
is not really expected to occur in normal use cases and even if it did
happen, the selected registrar information is not any worse than it was
before when only the last change from any registrar for being
advertized.

9008a3e44d Merge get_seqnum_igtk() driver op with get_seqnum()
IEEE 802.11w uses distinct key indexes (4 and 5) so the same
get_seqnum() handler can be used to fetch packet number for both
TKIP/CCMP and BIP(using IGTK).

Since the new get_seqnum_igtk() handler was not actually implemented by
any driver wrapper, this may also fix BIP/IGTK sequence number reporting
with driver_nl80211.c.

bab31499fd EAP-TTLS/PAP: User-Password obfuscation for zero length password
The password in User-Password AVP is padded to a multiple of 16 bytes
on EAP-TTLS/PAP. But when the password length is zero, no padding is
added. It doesn't cause connectivity issue. In fact, I could connect
with hostapd RADIUS server with zero length password.

I think it's better for obfuscation to pad the 16 bytes data when the
password length is zero with this patch.

e77e0a8320 Include functionality to support EAP-FAST unconditionally
Clean up the internal TLS implementation by removing conditional

will increase the size a big for non-EAP-FAST builds, but is quite
helpful in making src/tls/libtls.a with single build options. If
the potential size reduction is considered significant in the future,
this can be reconsider with a more library compatible way (e.g.,
external file with registration function, etc.).

d72aad942b nl80211: Clear BSS state mismatches with deauth as a workaround
There seem to be some cases in which wpa_supplicant and
cfg80211/mac80211 seem to have different understanding on
authentication/association state. Since cfg80211/mac80211 is very strict
on when it accepts new authentication/association/scan commands, try our
best at clearing such state mismatches by explicitly deauthenticating
from BSSes with which the driver claims we are associated with if we do
not have local information about such association.

e6b8efeba0 nl80211: Add debug prints for BSS status in scan results
Print what the kernel believes the current BSS status (authenticated
or associated) is in scan results. In addition, check whether this
matches with the state that wpa_supplicant believes the driver to be
in.

This does not change the actual behavior, but will provide information
that will help in debugging potential issues where cfg80211/mac80211
seems to get into a different state from wpa_supplicant. In addition,
this provides an easy location for a workaround that could be added to
clear cfg80211/mac80211 state for unknown BSSes.

6d798e8b7e Fix strict aliasing issue with the internal SHA-1 implementation
Need to define the workspace buffer properly to allow compiler to handle
strict aliasing between the incoming unsigned char[64] buffer as an u32
array. The previous version built with strict aliasing enabled can
result in SHA-1 producing incorrect results and consequently, with
4-way handshake failing.

This is based on a report and patch from Dan Williams <dcbw@redhat.com>
but with a different type (the union) used as a fix to avoid needing
extra type casting.

Discovered as part of the investigation of:

https://bugzilla.redhat.com/show_bug.cgi?id=494262#c32

if sha1 is built with gcc without turning off strict aliasing, it will
fail to correctly generate the hashes and will fail its own testcases as
well.

The WPS 1.0h specification is quite unclear on what exactly should be

looks like this should after all be the MAC Address of the Enrollee,
so change Registrar implementation to use that address instead of the
AP BSSID.

In addition, add validation code to the Enrollee implementation to
check the MAC Address value inside Credential (and also inside AP Settings)
to make sure it matches with the Enrollee's own address. However, since
there are deployed implementations that do not follow this interpretation
of the spec, only show the mismatch in debug information to avoid breaking

cannot be easily avoided with union-based type-punning due to struct

72ffc08242 WPS: SelectedRegistrar expiration for internal PIN registrar
Though we have such a timeout when handling SetSelectedRegistrar UPnP
message from an external registrar, it looks like we don't have one when
the internal registrar is activated for PIN connection. Thus we set the
SelectedRegistrar flag when AP is activated for PIN connection but we
never reset it - not by some timeout, nor when registration succeeds.
This lead to situations where AP everlastingly declare that it is
activated for WPS PIN connection when in reality it is not.

Use the same timeout (and also success with PIN) to clear the selected
registrar flag when using internal registrar, too.

workaround code in driver_nl80211.c alone is not enough since the
following disconnection event would clear wpa_supplicant authentication
state. To handle this, add some code to restore authentication state
when using userspace SME.

This workaround will hopefully become unnecessary in some point should

ebf214e670 NSS: Implement TLS PRF using new TLS extractor interface
This allows NSS to be used to derive EAP-TLS/PEAP/TTLS keying material.
NSS requires a patch from
https://bugzilla.mozilla.org/show_bug.cgi?id=507359
to provide the new API. In addition, that patch needs to be modified to
add the 16-bit context length value in SSL_ExportKeyingMaterial() only if
contextlen != 0 in order to match with the EAP-TLS/PEAP/TTLS use cases.
This issue seems to be coming from the unfortunate incompatibility in
draft-ietf-tls-extractor-07.txt (draft-ietf-tls-extractor-00.txt would
have used compatible PRF construction).

At this point, it is unclear how this will be resolved eventually, but
anyway, this shows a mechanism that can be used to implement EAP key
derivation with NSS with a small patch to NSS.

0194fedb46 driver_nl80211: Fix MLME key settings for static WEP
Current wpa_supplicant has a bug with WEP keys, it adds a zero-length
sequence counter field to netlink which the kernel doesn't accept.

Additionally, the kernel API slightly changed to accept keys only when
connected, so we need to send it the keys after that. For that to work
with shared key authentication, we also include the default WEP TX key
in the authentication command.

To upload the keys properly _after_ associating, add a new flag
WPA_DRIVER_FLAGS_SET_KEYS_AFTER_ASSOC_DONE indicating that the driver
needs the keys at that point and not earlier.

This effectively limits RADIUS messages to ~ 1500 Bytes, while they can

if an embedded NUL is detected. In theory, all the comparison routines
could be made to compare these strings as binary blobs (with additional
X.509 rules to handle some exceptions) and display NUL characters
somehow. Anyway, just rejecting the certificate will get rid of
potential problems with the C string getting terminated and it should
not really be used in certificates, so this should not break valid use

wpa_supplicant can now be built with FIPS capable OpenSSL for FIPS mode

ba30964b60 Force rebuilding of src/drivers between hostapd and wpa_supplicant
This is a (hopefully) temporary workaround to allow the same source code
tree to be used for building hostapd and wpa_supplicant without having
to manually force recompilation of some files. Currently, some of the
driver wrapper files need to be built separately for hostapd and
wpa_supplicant (#ifdef's in the files based on AP functionality).

This is somewhat racy as far as parallel make execution is concerned,
i.e., it may be necessary to run "make -j#" twice (plain "make" works
fine. Since this is supposed to be a temporary workaround, there is not
much point in trying to fix this with any more complex make processing.

else in the future.

077ed46d2b General revision of RoboSwitch driver
Attached is a patch for the RoboSwitch driver in trunk. It is a
general revision of the source code.

Changes:
- Improved IEEE 802.1X conformance ([1])
- Better conformity to Broadcom specifications
- Fixed compatibility with different chipset revisions

It is worth noting that performance may drop a little using the new
driver. This can be overcome by using "multicast_only=1" as a
parameter. In that case only packets to the PAE group address are
regarded, as the previous revision of the driver did. A more detailed
description of the parameter and it's consequences is available at [2]
(summary: use "multicast_only=1" whenever possible).

b08d177aad Use C99 designated initializers to cleanup driver_ops setup
These driver wrappers use UNIX domain sockets and as such, won't be
built with Microsoft compiler. Consequently, use of C99-style designated
initializers can be used to make these files easier to maintain. Only
driver_ndis.c needs to support the old C89-style due to Microsoft
compiler not supporting newer C standard.

ad1e68e6b5 Clean up HT40 scan and share nl80211 scanning code
Instead of adding a new driver_ops for fetching neighbor BSS data (that
nl80211 driver interface had to scan during initialization), share the
same scan operations that wpa_supplicant is using. This gets rid of
duplicated scan code in driver_nl80211.c (and better yet, removes large
part of old WEXT code).

hostapd interface initialization is now completed in a callback, if
needed, i.e., he_features channel/hw_mode selection can use as much time
as needed. This can also help with radar detection in the future.

c0a6190815 Fix SHA-256-based KDF when using CCMP as the pairwise cipher
IEEE 802.11r KDF uses key length in the derivation and as such, the PTK

using 512-bit PTK regardless of the negotiated cipher suite; this works

143a4bf632 WPS: Add a workaround for static WEP with Windows network probe
Windows XP and Vista clients can get confused about EAP-Identity/Request
when they probe the network with EAPOL-Start. In such a case, they may
assume the network is using IEEE 802.1X and prompt user for a
certificate while the correct (non-WPS) behavior would be to ask for the
static WEP key. As a workaround, use Microsoft Provisioning IE to
advertise that legacy 802.1X is not supported.

This seems to make Windows ask for a static WEP key when adding a new
network, but at least Windows XP SP3 was still marking IEEE 802.1X
enabled for the network. Anyway, this is better than just leaving the
network configured with IEEE 802.1X and automatic WEP key distribution.

9e783041fa Add a workaround for EAP-FAST with Cisco AP local RADIUS server
When using the internal TLS implementation, EAP-FAST unauthenticated
provisioning ends up proposing multiple cipher suites. It looks like
Cisco AP (at least 350 and 1200 series) local authentication server does
not know how to search cipher suites from the list and seem to require
that the last entry in the list is the one that it wants to use.
However, TLS specification requires the list to be in the client
preference order. As a workaround, ass anon-DH AES-128-SHA1 again at the
end of the list to allow the Cisco code to find it.

This fixed EAP-FAST provisioning with the following IOS version:

4ef1e644eb Determiner whether driver is wired at runtime based on capabilities
Do not use just the driver name for this since driver_ndis.c supports
both wired and wireless NDIS drivers and needs to indicate the driver
type after initialization.

ed843aaa33 WMM-AC: Fix hostapd processing of ADDTS Request and add test code
Calculate the estimated medium time using integer variables since there
is no real need to use floating point arithmetics here. In addition,
make sure there is no division by zero regardless of how invalid the
request from the station is. Reject invalid parameters and refuse
requests that would take most of the bandwidth by themselves.

Add test code into wpa_supplicant mlme.c to allow WMM-AC negotiation to
be tested with driver_test.

e1ee6b600b WPS: Add support for NFC out-of-band mechanism
The new file wps_nfc.c and ndef.c implements NFC device independent
operation, wps_nfc_pn531.c implements NFC device dependent operation.

This patch is only for the following use case:
- Enrollee = wpa_supplicant
- Registrar = hostapd internal Registrar

Following NFC methods can be used:
- Enrollee PIN with NFC
- Registrar PIN with NFC
- unencrypted credential with NFC

Encrypted credentials are not supported.

Enrollee side operation:

Registrar side operation:

Example configuration.
CONFIG_WPS=y
CONFIG_WPS_NFC=y
CONFIG_WPS_NFC_PN531=y

I used NFC device "NXP PN531". The NFC device access method is
confidential, so I used outer library. Please download below files from
https://www.saice-wpsnfc.bz/index.php

<WiFi test>
The hostapd/wpa_supplicant with this patch passed below tests on
"Wi-Fi WPS Test Plan Version 1.6".
4.2.5 Add device using NFC Method with password token
(I used SONY STA instead of NXP STA.)

4.2.6 Add device using NFC Method with configuration token

5.1.9 Add to AP using NFC Method with password token
through internal registrar
(I used SONY AP instead of NXP AP.)

5.1.10 Add to AP using NFC Method with configuration token
through internal registrar

3ae0800c5f WMM cleanup (WME -> WMM rename, comments, etc.)
This updates the terminogy to match with the final WMM specification. In
addition, some of the WMM TSPEC structure fields were in incorrect order
and used without byte order swapping. Those are also taken care of this
cleanup patch.

1fd4b0db7c Fix EAPOL/EAP reauthentication with external RADIUS server
The EAP server state machine will need to have special code in
getDecision() to avoid starting passthrough operations before having
completed Identity round in the beginning of reauthentication. This was
broken when moving into using the full authenticator state machine from
RFC 4137 in 0.6.x.

DH keys to allow the public key hash to be checked.

390cd3105d WPS UFD: Make build conditional on CONFIG_WPS_UFD=y
Not all embedded devices have USB interface and it is useful to be able
to remove unneeded functionality from the binary. In addition, the
current implementation has some UNIX specific calls in it which may make
it not compile cleanly on all target systems.

b414900a90 Reduce latency on starting WPS negotiation (TX EAPOL-Start earlier)
Reduce startWhen from 3 to 1 second if WPS is included in the build.
While this is done regardless of runtime WPS configuration, it is fine
to use a smaller value here in general. This cuts two seconds out from
WPS negotiation if the driver does not support addition of WPS IE into
the (Re)Association Request frame.

f2d8fc3d96 Do not try session resumption after EAP failure
If session resumption fails for any reason, do not try it again because
that is just likely to fail. Instead, drop back to using full
authentication which may work. This is a workaround for servers that do
not like session resumption, but do not know how to fall back to full
authentication properly.
