Jouni Malinen 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.

Jouni Malinen 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.

Jouni Malinen e0e14a7bc3 Move internal EAPOL authenticator defines into their own file
This is an initial step in further cleaning up the EAPOL authenticator
use to avoid requiring direct accesses to the internal data structures.
For now, number of external files are still including the internal
definitions from eapol_auth_sm_i.h, but eventually, these direct
references should be removed.

Jouni Malinen 03da66bd59 Remove src/crypto from default include path
In addition, start ordering header file includes to be in more
consistent order: system header files, src/utils, src/*, same
directory as the *.c file.
2009-11-29 23:04:43 +02:00
Jouni Malinen ffa2a30e33 Add Makefile for the new src/eapol_auth directory 2009-11-29 20:21:25 +02:00
Jouni Malinen b60d6f61e4 Make HOSTAPD_DUMP_STATE configurable with CONFIG_NO_DUMP_STATE
This removes the hardcoded definition from Makefile and cleans up
source code by moving the mail HOSTAPD_DUMP_STATE blocks into separate
files to avoid conditional compilation within files.
2009-11-29 20:18:47 +02:00
Jouni Malinen 281c950be4 Move EAPOL authenticator state machine into src/eapol_auth
This is now completely independent from hostapd-specific code, so
it can be moved to be under the src tree.
2009-11-29 20:03:28 +02:00
Jouni Malinen 2773ca093e Replace eap_type_text() with EAP server methods function
While this may not include knowledge of all EAP methods since this
depends on build configuration, it is better to not have to include
ieee802_1x.h into eapol_sm.c.
2009-11-29 18:57:15 +02:00
Jouni Malinen 0c3abf8d22 Add driver wrapper callback for WPS push button pressed
This avoids the need to include ../hostapd/wps_hostapd.h into the
driver wrappers.

Jouni Malinen 67470d5112 Remove some unneeded header file inclusions 2009-11-29 18:07:08 +02:00
Jouni Malinen bcd154c343 Include sta_flags.h explicitly, not via sta_info.h 2009-11-29 18:00:39 +02:00
Jouni Malinen 90973fb2fd Remove src/common from default header file path
This makes it clearer which files are including header from src/common.
Some of these cases should probably be cleaned up in the future not to
do that.

In addition, src/common/nl80211_copy.h and wireless_copy.h were moved
into src/drivers since they are only used by driver wrappers and do not
need to live in src/common.

Jouni Malinen 6ae9318536 Split scan processing for RSN preauthentication into parts
This avoids passing the raw scan results into the RSN code and by
doing so, removes the only dependency on src/drivers from the
src/rsn_supp code (or from any src subdirectory for that matter).
2009-11-29 17:06:03 +02:00
Jouni Malinen 120158cc8b Move uuid_gen_mac_addr() from uuid.c into src/wps

Jouni Malinen 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.

Jouni Malinen 5843e1c9a6 Move acct_interim_interval away from RADIUS client configuration

Jouni Malinen 8e2c104fa1 Resolve some sparse warnings
Mainly, this is including header files to get definitions for functions

Jouni Malinen ec8d20187d Remove obsoleted get_scan_results() driver_ops
This has now been replaced with get_scan_results2() in every
in-tree driver.
2009-11-23 21:33:37 +02:00
Jouni Malinen c2e8d0a092 Remove deprecated scan and set_probe_req_ie driver_ops
These have been replaced with scan2 driver_ops that provides all

2009-11-23 21:13:46 +02:00
Jouni Malinen 4a867032ae Remove deprecated driver_ops handlers
This gets rid of previously deprecated driver_ops handlers set_wpa,
set_drop_unencrypted, set_auth_alg, set_mode. The same functionality
can be achieved by using the init/deinit/associate handlers.
2009-11-23 20:22:38 +02:00
Jouni Malinen e90bba4c59 Add cleared deprecation notes on iwl,ndiswrapper,madwifi(sta) wrappers
These driver wrappers should not be used anymore; WEXT should be used
instead. However, there may still be users stuck on older kernel versions
that may require driver specific wrappers, so the source code still
remains in the repository.

Jouni Malinen 642187d6bf Merge set_key and hapd_set_key driver_ops into a single function 2009-11-23 16:58:32 +02:00
Jouni Malinen fd7a5dd15f Move HOSTAPD_MTU definition into driver_hostap.c
This moves the MTU definition into driver_hostap.c since it was really
meant to be specific to this driver. Since this was the last remaining
definition in hostapd_defs.h, remove that header file as unnecessary.
2009-11-23 16:21:07 +02:00
Jouni Malinen 0715247aa8 Remove unneeded set-MTU operation from drivers
This code was copied from driver_hostap.c where it is used with the
special wlan#ap interface. It was not supposed to be used to change
the MTU for a normal data interface.
2009-11-23 16:17:41 +02:00
Jouni Malinen d994a9b54e Move definitions away from hostapd_defs.h

Jouni Malinen c1bb3e0a62 nl80211: Build some client functionality unconditionally
Even though this makes the hostapd version a bit larger, the code will
be easier to maintain with the reduced number of complex ifdef blacks.

Jouni Malinen dbb2618300 nl80211: Remove last remaining WEXT code
Clean up driver_nl80211.c by gettign rid of the last remaining WEXT use.
This requires that a recent mac80211 version is used to get full protection
in station mode via the authorized flag (IEEE 802.1X PAE).

Jouni Malinen 3c2166d63c WPS: Do not try to send byebye advertisements if socket is not valid
If initialization fails, we could potentially try to sendto() on -1

Jouni Malinen 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.

Jouni Malinen a34a330706 WPS ER: Use random event identifier in event URL
This avoids some issues in cases where the ER has been started and
stopped multiple times on the same address and an AP may have stored
multiple event notification addresses for the same ER. The random
identifier allows the ER to filter out unexpected messages from further
processing.

Jouni Malinen 3f6dc111ff WPS: Cleanup subscription URL list handling
Do not give the allocated memory to the subscription code since it was
not using it as-is anyway. This makes it easier to understand who owns
the allocation an is responsible of freeing it. This may potentially
fix some memory leaks on error paths.

Jouni Malinen 4bdd556886 WPS: Fix MAC Address inside Credential be that of Enrollee's
The WPS 1.0h specification is quite unclear on what exactly should be
used as the MAC Address value in the Credential and AP Settings. It
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
interoperability with existing devices.

Jouni Malinen 00785aba71 WPS: Remove unused WFA WLANConfig Service actions
This removes following WFA WLANConfig Service actions and the related
state variables: GetAPSettings, SetAPSettings, DelAPSettings,
GetSTASettings, SetSTASettings, DelSTASettings, RebootAP,
ResetAP, RebootSTA, ResetSTA.

While WFA WLANConfig Service version 1.0 claims that some of these are
mandatory to implement for an AP, there are no known implementations
supporting these actions neither in an AP/proxy or an External Registrar
that would use them. These are unlikely to be supported in the future
either and as such, it is just simpler to get rid of them to clean up
the implementation and reduce code size.

Jouni Malinen 5a641ae01e Use type-punning to avoid breaking strict aliasing rules
While the actual use here would be unlikely to be broken by any C
optimization, it is better to use explicit union construction to let

Jouni Malinen 0ae7b08691 Work around some gcc 4.4 strict-aliasing warnings
gcc 4.4 ends up generating strict-aliasing warnings about some very common
networking socket uses that do not really result in a real problem and
cannot be easily avoided with union-based type-punning due to struct
definitions including another struct in system header files. To avoid having
to fully disable strict-aliasing warnings, provide a mechanism to hide the
typecast from aliasing for now. A cleaner solution will hopefully be found
in the future to handle these cases.

Andriy Tkachuk 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.

Jouni Malinen 6d6f4bb87f nl80211: Work around mac80211 limitation on (re)auth when authenticated
mac80211 does not currently allow (re)authentication when we are already
authenticated. In order to work around this, force deauthentication if
nl80211 authentication command fails with EALREADY. Unfortunately, the
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
mac80211 start accepting new authentication requests even when in
authenticated state.

Jouni Malinen 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.

Johannes Berg 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.

When Linux has Path MTU discovery enabled, it sets by default the DF bit

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

These could, at least in theory, be used to generate unexpected common
name or subject alternative name matches should a CA sign strings with
NUL (C string termination) in them. For now, just reject the certificate
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
cases.

Jouni Malinen 76f04b38b0 Preliminary support for FIPS mode operation with OpenSSL
wpa_supplicant can now be built with FIPS capable OpenSSL for FIPS mode
operation. Currently, this is only enabling the FIPS mode in OpenSSL
without providing any higher level enforcement in wpa_supplicant.
Consequently, invalid configuration will fail during the authentication
run. Proper configuration (e.g., WPA2-Enterprise with EAP-TLS) allows
the connection to be completed.

Jouni Malinen 0a5d68aba5 Make hash functions return error value
Some crypto libraries can return in these functions (e.g., if a specific
hash function is disabled), so we better provide the caller a chance to
check whether the call failed. The return values are not yet used
anywhere, but they will be needed for future changes.

Masashi Honma d43430d43d NetBSD: Fix wired IEEE 802.1X problem
On NetBSD 5.0, when I use wired 802.1X, "Invalid argument" occurs
on SIOCADDMULTI ioctl and 802.1X fails.

I tried FreeBSD code, but "Address family not supported by protocol family"
occurs on SIOCADDMULTI ioctl and 802.1X fails, too.

This patch solves this issue.

I have tested with these:
OS : NetBSD 5.0
EAP : EAP-MD5
Switch : CentreCOM 8724SL

Jouni Malinen 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.

Jouni Malinen 6b23b70445 Avoid a theoretical integer overflow in base64_encode()
If base64_encode() were to be used with a huge data array, the
previous version could have resulted in overwriting the allocated
buffer due to an integer overflow as pointed out in
http://www.freebsd.org/cgi/query-pr.cgi?pr=137484. However, there
are no know use cases in hostapd or wpa_supplicant that would do that.
Anyway, the recommended change looks reasonable and provides additional
protection should the base64_encode() function be used for something
else in the future.

Johannes Berg 7a47d567cf hostapd: fix auth encryption
hostapd currently tries to encrypt all auth frames,
except for "OPEN" and "SHARED with transaction 3".
This means that it will send an encrypted "unknown

this by changing the logic to only encrypt shared
key auth frames with transaction 3.
