a1f11e34c4 Use os_memdup()
This leads to cleaner code overall, and also reduces the size
of the hostapd and wpa_supplicant binaries (in hwsim test build
on x86_64) by about 2.5 and 3.5KiB respectively.

The mechanical conversions all over the code were done with
the following spatch:

    @@
    expression SIZE, SRC;
    expression a;
    @@
    -a = os_malloc(SIZE);
    +a = os_memdup(SRC, SIZE);
    <...
    if (!a) {...}
    ...>
    -os_memcpy(a, SRC, SIZE);

de01f254a6 RADIUS server: Fix error paths in new session creation
radius_server_session_free() does not remove the session from the
session list and these radius_server_get_new_session() error paths ended
up leaving a pointer to freed memory into the session list. This
resulted in the following operations failing due to use of freed memory.

Fix this by using radius_server_session_remove() which removes the entry
from the list in addition to calling radius_server_session_free().

79329ae0aa P2P: Verify local driver preferred frequencies for P2P use cases
Previously the peer operating channel preference was accepted if the
indicated frequency was listed in the local preference list from the
driver. This was assuming that the driver included only channels that
are currently enabled for GO operation. Since that might not be the
case, filter the local preference list by doing an explicit validation
of the indicated channels for P2P support.

This moves the similar validation steps from two other code paths in
p2p_check_pref_chan_recv() and p2p_check_pref_chan_no_recv() into a
common filtering step in p2p_check_pref_chan() for all three cases.

This avoids issues to start the GO in cases where the preferred
frequency list from the driver may include channels that are not
currently enabled for P2P GO use (e.g., 5 GHz band in world roaming
configuration).

Issue: When 2 peers are running MACsec in PSK mode with CA
established, if the interface goes down and comes up after

Root cause: This is because retry_count of both the peers

respond. This is clear deadlock situation where peer A waits
for MKA packets from peer B to wake up and vice-versa.

9e2afe10e6 EAP-SIM: Don't use anonymous identity in phase2
The "anonymous_identity" configuration field has more than one
semantic meaning. For tunneled EAP methods, this refers to the
outer EAP identity. For EAP-SIM, this refers to the pseudonym
identity. Also, interestingly, EAP-SIM can overwrite the
"anonymous_identity" field if one is provided to it by the
authenticator.

When EAP-SIM is tunneled within an outer method, it makes sense
to only use this value for the outer method, since it's unlikely
that this will also be valid as an identity for the inner EAP-SIM
method. Also, presumably since the outer method protects the
EAP-SIM transaction, there is no need for a pseudonym in this
usage.

Similarly, if EAP-SIM is being used as an inner method, it must
not push the pseudonym identity using eap_set_anon_id() since it
could overwrite the identity for the outer EAP method.

bd6ec7f7ca Fix MAC ACL query freeing on deinit
hapd->acl_cache and hapd->acl_queries were not reset back to NULL in
hostapd_acl_deinit() when cached results and pending ACL queries were
freed. This left stale pointers to freed memory in hapd. While this was
normally followed by freeing of the hapd data, it is possible to re-use
that hapd when disabling and re-enabling an interface. That sequence
could result in use of freed memory if done while there were cached
results or pending ACL operations with a RADIUS server (especially, if
that server did not reply).

Fix this by setting hapd->acl_queries to NULL when the pending entries
are freed.

e54691106b mka: Some bug fixes for MACsec in PSK mode
Issue:
------
The test setup has 2 peers running MACsec in PSK mode, Peer A with
MAC address higher than MAC Address of peer B. Test sequence is
1. Peer B starts with actor_priority 255
2. Peer A starts with priority 16, becomes key server.
3. Peer A stops..
4. Peer A restarts with priority 255, but because of the stale values
participant->is_key_server(=TRUE) and participant->is_elected(=TRUE)
it continues to remain as Key Server.
5. For peer B, key server election happens and since it has lower MAC
address as compared to MAC address of A, it becomes the key server.
Now we have 2 key servers in CA and is not correct.

Root-cause & fix:
-----------------
When number of live peers become 0, the flags such lrx, ltx, orx,
otx, etc. need to be cleared. In MACsec PSK mode, these stale values
create problems while re-establishing CA.

db5e53cb06 mesh: Fix struct hostapd_data initialization
The local custom version of allocating and initializing struct
hostapd_data within wpa_supplicant_mesh_init() is problematic. This has
already missed couple of initialization steps that are required. Instead
of trying to remember to keep this up to date, use
hostapd_alloc_bss_data() so that there is only one place for this
initialization.

This is fixing a recent issue where FILS HLP started using
hapd->dhcp_server and expected that to be initialized to -1. For the
mesh case, that did not happen and when removing the interface, the FILS
HLP implementation ended up unregistering eloop socket for
hapd->dhcp_server (= 0). This could result in missing socket callbacks
for an arbitrary socket.

d77f330418 FILS: Fix AES-SIV AAD for (Re)Association Request frame decryption
The hostapd processing of the AES-SIV AAD was incorrect. The design for
the AAD changed between P802.11ai/D7.0 and D8.0 from a single vector
with concatenated data to separate vectors. The change in the
implementation had missed the change in the aes_siv_decrypt() call for
the num_elem parameter. This happened to work with the mac80211
implementation due to a similar error there.

Fix this by using the correct numbers of vectors in the SIV AAD so that
all the vectors get checked. The last vector was also 14 octets too long
due to incorrect starting pointer, so fix that as well. The changes here
are not backwards compatible, i.e., a similar fix in the Linux mac80211
is needed to make things interoperate again.

bb3ea71a23 ERP: Fix rIK derivation
Unlike the EMSKname and rRK derivations, rIK derivation is actually
using the "optional data" component in the context data (see RFC 5295).
RFC 6696 defines that optional data to be the cryptosuite field for rIK.
This was missing from the previous implementation and that resulted in
incorrect rIK being derived.

In addition, the rIK Label string does not actually include the "EAP "
prefix in the way as the rRK Label in RFC 6696 does. This would also
have resulted in incorrect rIK value.

Fix rIK derivation by adding the cryptosuite value into the KDF context
data and fixing the label string. This change is not backwards
compatible and breaks all ERP use cases (including FILS shared key
authentication) with older (broken) and new (fixed)
hostapd/wpa_supplicant builds.

510fc2dfc9 Fix AKM suite selectors for FILS and Suite B
IEEE 802.11 standard defines the suite selectors in <OUI>:<subtype>
format where OUI uses hexadecimal format and subtype decimal format.
These WLAN_AKM_SUITE_* definitions ended up getting written incorrectly
by interpretting the decimal part as hexadecimal and as such, by having
an incorrect value. However, the older RSN_AUTH_KEY_MGMT_* values were
defined with correct values and those definitions were used in most
locations.

This commit fixes the AKM suite selector values in RADIUS WLAN-AKM-Suite
attribute for FILS and Suite B. In addition, the AKM values used in
nl80211 driver configuration (NL80211_ATTR_AKM_SUITES) are fixed for the
Suite B cases.

4d77d80edd mesh: Add MESH_PMKSA_GET/ADD commands
These commnds are mesh version of PMKSA_GET/ADD commands. So the usage
and security risk is similar to them. Refer to
commit 3459381dd2 ('External persistent
storage for PMKSA cache entries') also.

The MESH_PMKSA_GET command requires peer MAC address or "any" as an
argument and outputs appropriate stored PMKSA cache. And the
MESH_PMKSA_ADD command receives an output of MESH_PMKSA_GET and re-store
the PMKSA cache into wpa_supplicant. By using re-stored PMKSA cache,
wpa_supplicant can skip commit message creation which can use
significant CPU resources.

The output of the MESH_PMKSA_GET command uses the following format:
<BSSID> <PMKID> <PMK> <expiration in seconds>

The example of MESH_PMKSA_ADD command is this.
MESH_PMKSA_ADD 02:00:00:00:03:00 231dc1c9fa2eed0354ea49e8ff2cc2dc cb0f6c9cab358a8146488566ca155421ab4f3ea4a6de2120050c149b797018fe 42930

This functionality is disabled by default and can be enabled with

fa67debf4c Fix duplicate Reassociation Request frame dropping
Relational operators (==) have higher precedence than the ternary
conditional in C. The last_subtype check for association/reassociation
was broken due to incorrect assumption about the precedence. Fix this by
adding parenthesis around the ternary conditional.

The previous implementation worked for Association Request frames by
accident since WLAN_FC_STYPE_ASSOC_REQ happens to have value 0 and when
the last receive frame was an Association Request frame, the
sta->last_subtype == reassoc check was true and non-zero
WLAN_FC_STYPE_REASSOC_REQ was interpreted as true. However, this was
broken for Reassociation Request frame. reassoc == 1 in that case could
have matched received Association Response frame (subtype == 1), but
those are not received in AP mode and as such, this did not break other
behavior apart from not being able to drop duplicated Reassociation
Request frames.

1f0fdaf0e4 Fix race condition between AssocResp callback and 4addr event
It is apparently possible for the NL80211_CMD_UNEXPECTED_4ADDR_FRAME
event to be delivered to hostapd before the NL80211_CMD_FRAME_TX_STATUS
event for (Re)Association Response frame. This resulted in the 4-address
WDS mode not getting enabled for a STA. This could occur in particular
when operating under heavy load and the STA is reconnecting to the same
AP in a sequence where Deauthentication frame is followed immediately by
Authentication frame and the driver event processing gets delayed due to
removal of the previous netdev taking time in the middle of this
sequence.

Fix this by recording a pending item for 4-address WDS enabling if the
NL80211_CMD_UNEXPECTED_4ADDR_FRAME event would have been dropped due to
incompleted association and then process this pending item if the TX
status for the (Re)Association Response frame is received and it shows
that the frame was acknowledged.

3459381dd2 External persistent storage for PMKSA cache entries
This adds new wpa_supplicant control interface commands PMKSA_GET and
PMKSA_ADD that can be used to store PMKSA cache entries in an external
persistent storage when terminating a wpa_supplicant process and then
restore those entries when starting a new process. The previously added
PMKSA-CACHE-ADDED/REMOVED events can be used to help in synchronizing
the external storage with the memory-only volatile storage within
wpa_supplicant.

"PMKSA_GET <network_id>" fetches all stored PMKSA cache entries bound to
a specific network profile. The network_id of the current profile is
available with the STATUS command (id=<network_id). In addition, the
network_id is included in the PMKSA-CACHE-ADDED/REMOVED events. The
output of the PMKSA_GET command uses the following format:

<BSSID> <PMKID> <PMK> <reauth_time in seconds> <expiration in seconds>
<akmp> <opportunistic>

For example:

02:00:00:00:03:00 113b8b5dc8eda16594e8274df4caa3d4 355e98681d09e0b69d3a342f96998aa765d10c4459ac592459b5efc6b563eff6 30240 43200 1 0
02:00:00:00:04:00 bbdac8607aaaac28e16aacc9152ffe23 e3dd6adc390e685985e5f40e6fe72df846a0acadc59ba15c208d9cb41732a663 30240 43200 1 0

The PMKSA_GET command uses the following format:

<network_id> <BSSID> <PMKID> <PMK> <reauth_time in seconds> <expiration
in seconds> <akmp> <opportunistic>

(i.e., "PMKSA_ADD <network_id> " prefix followed by a line of PMKSA_GET
output data; however, the reauth_time and expiration values need to be
updated by decrementing them by number of seconds between the PMKSA_GET
and PMKSA_ADD commands)

For example:

PMKSA_ADD 0 02:00:00:00:03:00 113b8b5dc8eda16594e8274df4caa3d4 355e98681d09e0b69d3a342f96998aa765d10c4459ac592459b5efc6b563eff6 30140 43100 1 0
PMKSA_ADD 0 02:00:00:00:04:00 bbdac8607aaaac28e16aacc9152ffe23 e3dd6adc390e685985e5f40e6fe72df846a0acadc59ba15c208d9cb41732a663 30140 43100 1 0

This functionality is disabled be default and can be enabled with
CONFIG_PMKSA_CACHE_EXTERNAL=y build configuration option. It should be
noted that this allows any process that has access to the wpa_supplicant
control interface to use PMKSA_ADD command to fetch keying material
(PMK), so this is for environments in which the control interface access
is restricted.

wpa_supplicant left the previously learned dev->info.wfd_subelems in
place whenever the new message did not include wfd_subelems.

In addition to fixing the clearing of the old wfd_subelems, this
resolves another issue. As "wfd_changed" variable becomes true even when
peer stops sending wfd_subelems and dev->info.wfd_subelems has an old
value, a new P2P-DEVICE-FOUND event notification was sent again and
again to upper layers whenever a new discovery response was received
from the peer that previously advertised WFD subelements.

The error sequence could happen in the go_neg_with_bss_connected test

0f5eb69f85 Use eloop timeout for post-EAP-Failure wait before disconnection
Previously, os_sleep() was used to block the hostapd (or wpa_supplicant
AP/P2P GO mode) processing between sending out EAP-Failure and
disconnecting the STA. This is not ideal for couple of reasons: it
blocks all other parallel operations in the process and it leaves a
window during which the station might deauthenticate and the AP would
have no option for reacting to that before forcing out its own
Deauthentication frame which could go out after the STA has already
started new connection attempt.

Improve this design by scheduling an eloop timeout of 10 ms instead of
the os_sleep() call and perform the delayed operations from the eloop
callback function. This eloop timeout is cancelled if the STA
disconnects or initiates a new connection attempt before the 10 ms time
is reached. This gets rid of the confusing extra Deauthentication frame
in cases where the STA reacts to EAP-Failure by an immediate
deauthentication.

It is set when we explicitly initial a connect request using
wpa_supplicant. If the association was initiated outside of

missed the part about the possibility of last_scan_cmd == 0 and an

By setting the new hostapd configuration option multicast_to_unicast=1,
hostapd configures this AP to perform multicast to unicast conversion.

When enabled, all multicast packets with ethertype ARP, IPv4, or IPv6
(possibly within an 802.1Q header) will be sent out to each station once
with the destination (multicast) MAC address replaced by the station's
MAC address. Note that this may break certain expectations of the
receiver, e.g., the ability to drop unicast IP packets encapsulated in
multicast L2 frames, or the ability to not send destination unreachable
messages in such cases.

This also does not implement Directed Multicast Service (DMS).

08032c7418 Remove inactivity timeout for wired interfaces
We should unconditionally remove inactivity timers for wired network
cases. This commit checks for this after a new station association:

   hapd->iface->drv_flags & WPA_DRIVER_FLAGS_WIRED

and then cancels the timeout and does not register a new one.

It prints out a debug message like this:

1476740180.276286: IEEE 802.1X: 00:02:00:00:00:07 CTRL_DIR entering
state FORCE_BOTH
1476740180.276295: hostapd_new_assoc_sta: canceled wired ap_handle_timer
timeout for 00:02:00:00:00:07

This was tested on a debian jessie amd64 system with a configured 120
second inactivity timer and the session did not timeout.

a1fce3911f nl80211: Optimize memory use in nl80211_get_assoc_freq()
Do not use the generic bss_info_handler() design to fetch all scan
results into temporary memory buffer. Instead, use a separate BSS info
handler that fetches the requested information without fully parsing the
BSS entries and without allocating any memory for collecting all the
results.

This is also simplifying bss_info_handler() and nl80211_parse_bss_info()
design by getting rid of the special case that was used only for
nl80211_get_assoc_freq() and not normal scan result fetching.

b72a01bc5a nl80211: Split bss_info_handler() into a separate parser function
This allows a single scan result to be parsed at a time. This is a step
towards optimizing scan result fetching without having to allocate
memory for all entries at the same time.

cfadab269f nl80211: Move duplicate scan result removal to bss.c
The way the removal of duplicated (one per frequency) BSS entries in the
cfg80211 scan results were removed in driver_nl80211_scan.c
bss_info_handler() depended on having the full scan results available to
allow iteration through the other entries. This is problematic for the
goal of being able to optimize memory allocations for scan result
fetching in a manner that would not build the full result buffer in
memory.

Move this duplicate removal into bss.c since it has sufficient
information available for doing the same determination of which one of
two BSS entries is more current.
