Michael Braun a5e81ba9eb Fix STA VLAN bind for RSN pre-authentication case
Previously, during RSN preauthentication, ap_sta_bind_vlan() was called,
which fails for non-zero sta->vlan_id as the station is not known to the
kernel driver.

Fix this by binding the station only if it is associated. If it is not
associated, ap_sta_bind_vlan() will be done later during association.

In addition, reject Access-Accept if the returned VLAN ID is not valid
in the current hostapd configuration.

Nick Kralevich d447cd596f Updates for stricter automatic memcpy bounds checking
Both Android's libc and glibc support _FORTIFY_SOURCE, a compiler
and libc feature which inserts automatic bounds checking into
common C functions such as memcpy() and strcpy(). If a buffer
overflow occurs when calling a hardened libc function, the
automatic bounds checking will safely shutdown the program and
prevent memory corruption.

Android is experimenting with _FORTIFY_SOURCE=3, a new fortify
level which enhances memcpy() to prevent overflowing an element
of a struct. Under the enhancements, code such as

  struct foo {
    char empty[0];
    char one[1];
    char a[10];
    char b[10];
  };

  int main() {
    foo myfoo;
    int n = atoi("11");
    memcpy(myfoo.a, "01234567890123456789", n);
    return 0;
  }

will cleanly crash when the memcpy() call is made.

Fixup hostap code to support the new level. Specifically:

* Fixup sha1_transform so it works with the enhanced bounds checking.
The old memcpy() code was attempting to write to context.h0, but that
structure element is too small and the write was extending (by design)
into h1, h2, h3, and h4. Use explicit assignments instead of
overflowing the struct element.

* Modify most of the structures in ieee802_11_defs.h to use ISO C99
flexible array members (https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html)
instead of a zero length array. Zero length arrays have zero length,
and any attempt to call memcpy() on such elements will always overflow.
Flexible array members have no such limitation. The only element not
adjusted is probe_req, since doing so will generate a compile time error,
and it's not obvious to me how to fix it.

Jouni Malinen fa0e715100 Use tls_connection_prf() for all EAP TLS-based key derivation
tls_openssl.c is the only remaining TLS/crypto wrapper that needs the
internal PRF implementation for EAP-FAST (since
SSL_export_keying_material() is not available in older versions and does
not support server-random-before-client case). As such, it is cleaner to
assume that TLS libraries support tls_connection_prf() and move the
additional support code for the otherwise unsupported cases into

Jouni Malinen a52410c29f Allow PSK/passphrase to be set only when needed
The new network profile parameter mem_only_psk=1 can be used to specify
that the PSK/passphrase for that network is requested over the control
interface (ctrl_iface or D-Bus) similarly to the EAP network parameter
requests. The PSK/passphrase can then be configured temporarily in a way
that prevents it from getting stored to the configuration file.

For example:

Event:
CTRL-REQ-PSK_PASSPHRASE-0:PSK or passphrase needed for SSID test-wpa2-psk

Response:
CTRL-RSP-PSK_PASSPHRASE-0:"qwertyuiop"

Note: The response value uses the same encoding as the psk network
profile parameter, i.e., passphrase is within double quotation marks.

information to upper layer software that may use such events to track
DFS/CAC state. This makes the offloaded DFS implementation more
consistent with the DFS-in-hostapd behavior.

Jouni Malinen 48ec6942cb Fix Linux packet socket workaround to not close the socket too easily
Commit e6dd8196e5 ('Work around Linux
packet socket regression') closed the workaround socket on the first
received EAPOL frame from the main packet socket. This can result in
closing the socket in cases where the kernel does not really work in the
expected way during the following initial association since
reauthentication/rekeying using EAPOL frames happens while operstate is
not dormant and as such, the frames can get delivered through the main
packet socket.

Fix this by closing the workaround socket only in case the first EAPOL
frame is received through the main packet socket. This case happens
while the interface is in dormant state and as such, is more likely to
show the more restricted case of kernel functionality.

In order to avoid processing the received EAPOL frames twice, verify a
checksum of the frame contents when receiving frames alternatively from
the main packet socket and the workaround socket.

Jouni Malinen 0d2f324d67 P2P: Fix send_action_in_progress clearing in corner cases
It is possible for an Action frame TX operation to be stopped in a way
that results in the TX status callback function not being called. This
could happen, e.g., when P2P_STOP_FIND was issued while waiting for PD
Response TX status. This specific case ended in leaving
p2p->send_action_in_progress set to 1 and that ending up stopping a
future TX operation when p2p_send_action_cb() gets called with
p2p->pending_action_state == P2P_NO_PENDING_ACTION.

This could result in reception of a fragmented service discovery
response failing due to the GAS sequence getting stopped when receiving
TX callback for the first GAS comeback request. That sequence could be
hit in mac80211_hwsim tests when p2p_listen_and_offchannel_tx was
followed by p2p_service_discovery_fragmentation (even after a long time
since this was on dev1 and there could be even 10 minutes between these
test cases).

Fix this issue by clearing send_action_in_progress whenever stopping
pending P2P operation with p2p_stop_find (or P2P_FLUSH for that matter).

Masashi Honma 0cb5f8d945 mesh: Fix inactivity timer for 32 bit system
Commit 5a2a6de6a5 ('mesh: Make inactivity
timer configurable') has a problem on 32 bit systems. Setting
NL80211_MESHCONF_PLINK_TIMEOUT to 0xffffffff causes expiration of STA in
a minute by NL80211_CMD_DEL_STATION event. this is the kernel rule for
STA expiration:

(current jiffies) > (frame Rx jiffies + NL80211_MESHCONF_PLINK_TIMEOUT * 250)

On a 32 bit system, the right side could overflow and be unexpected
small value if NL80211_MESHCONF_PLINK_TIMEOUT is sufficiently large. STA
expiration occurs by this reason.

This patch solves the problem by disabling the STA expiration
functionality in mac80211. However, old kernel does not support
disabling it. If so, this patch sets mac80211 inactivity timer 60
seconds into future from the wpa_supplicant inactivity timer.

And I mis-understood that mesh_max_inactivity=0 disables inactivity
timer in wpa_supplicant. This commit fixes it also.

Previously, a channel with even a single scan/survey result missing
information was skipped in ACS. This may not be desirable in cases when
multiple scan iterations are used (which is the case by default in

set of results. Calculate the average interference factor as an average
of the iterations that did provide complete values.

This seems to help with some cases, e.g., when ath9k may not be able to
report the noise floor for all channels from the first scan iteration
immediately after the driver has been loaded, but then returns it for
all other scan iterations.

Jouni Malinen 68fa00c341 ACS: Allow specific channels to be preferred
The new acs_chan_bias configuration parameter is a space-separated list
of <channel>:<bias> pairs. It can be used to increase (or decrease) the
likelihood of a specific channel to be selected by the ACS algorithm.
The total interference factor for each channel gets multiplied by the
specified bias value before finding the channel with the lowest value.
In other words, values between 0.0 and 1.0 can be used to make a channel
more likely to be picked while values larger than 1.0 make the specified
channel less likely to be picked. This can be used, e.g., to prefer the
commonly used 2.4 GHz band channels 1, 6, and 11 (which is the default
behavior on 2.4 GHz band if no acs_chan_bias parameter is specified).

count overlapping channels together in this way or whether that is
already covered in channel survey results, it is clear that this summing
of three to five values together and then comparing the sum rather than
average of some kind gives too much preference to the channels at the
edges of the band by assuming that there is no interference whatsoever
outside the band.

Use weighted average of the interference factors rather than a sum from
different number of values. For now, the adjacent 2.4 GHz channels get
weight of 0.85 (1.0 for the main channel itself) and the neighboring
channels to those adjacent ones get 0.55 weight. Band-edge channels are
handled in a way that takes average over the channels that were actually
considered instead of assuming zero interference from neighboring bands.

Krishna Vamsi 2c0efd9e49 P2P: Fix stopping on search after SD callback
If p2p_find_timeout triggers after starting SD but before getting TX
status for send action, unwanted search could get triggered again when
TX status arrives though p2p_find_timeout moved the state to P2P_IDLE by
then. p2p_continue_find() would then move the state to P2P_SEARCH again.
Do not trigger the find operation from this context if state is
P2P_IDLE to avoid this.

Jouni Malinen d027c7b118 Fix 20/40 MHz co-ex report processing with obss_interval=0
If OBSS scan interval is not set, the AP must not schedule a timeout to
restore 40 MHz operation immediately after having moved to a 20 MHz
channel based on an unsolicited co-ex report. Fix this by scheduling the
timeout only if obss_interval is non-zero.

Since we do not currently support AP doing OBSS scans after the initial
BSS setup, this means practically that 40-to-20 MHz transition is
allowed, but 20-to-40 MHz is not with obss_interval=0. The latter gets
enabled if obss_interval is set to a non-zero value so that associated
STAs can take care of OBSS scanning.

Jouni Malinen 7f7bfba919 Add an option allow canned EAP-Success for wired IEEE 802.1X
For wired IEEE 802.1X authentication, phase1="allow_canned_success=1"
can now be used to configure a mode that allows EAP-Success (and
EAP-Failure) without going through authentication step. Some switches
use such sequence when forcing the port to be authorized/unauthorized or
as a fallback option if the authentication server is unreachable. By
default, wpa_supplicant discards such frames to protect against
potential attacks by rogue devices, but this option can be used to
disable that protection for cases where the server/authenticator does
not need to be authenticated.

When enabled, this mode allows EAP-Success/EAP-Failure as an immediate
response to EAPOL-Start (or even without EAPOL-Start) and EAP-Success is
also allowed immediately after EAP-Identity exchange (fallback case for
authenticator not being able to connect to authentication server).

wpa_supplicant used to request user to re-enter username/password if the
server indicated that EAP-MSCHAPv2 (e.g., in PEAP Phase 2)
authentication failed (E=691), but retry is allowed (R=1). This is a
reasonable default behavior, but there may be cases where it is more
convenient to close the authentication session immediately rather than
wait for user to do something.

Add a new "mschapv2_retry=0" option to the phase2 field to allow the
retry behavior to be disabled. This will make wpa_supplicant abort
authentication attempt on E=691 regardless of whether the server allows
retry.

Jouni Malinen e6dd8196e5 Work around Linux packet socket regression
Linux kernel commit 576eb62598f10c8c7fd75703fe89010cdcfff596 ('bridge:
respect RFC2863 operational state') from 2012 introduced a regression
for using wpa_supplicant with EAPOL frames and a station interface in a
bridge. Since it does not look like this regression is going to get
fixed any time soon (it is already two years from that commit and over
1.5 from a discussion pointing out the regression), add a workaround in
wpa_supplicant to avoid this issue.

The wpa_supplicant workaround uses a secondary packet socket to capture
all frames (ETH_P_ALL) from the netdev that is in a bridge. This is
needed to avoid the kernel regression. However, this comes at the price
of more CPU load. Some of this is avoided with use of Linux socket
filter, but still, this is less efficient than a packet socket bound to
the specific EAPOL ethertype. The workaround gets disabled
automatically, if the main packet socket interface on the bridge
interface turns out to be working for RX (e.g., due to an old kernel
version being used or a new kernel version having a fix for the
regression). In addition, this workaround is only taken into use for the
special case of running wpa_supplicant with an interface in a bridge.

Jouni Malinen 6b46bfa751 WPS: Re-fix an interoperability issue with mixed mode and AP Settings
Commit ce7b56afab ('WPS: Fix an
interoperability issue with mixed mode and AP Settings') added code to
filter M7 Authentication/Encryption Type attributes into a single bit
value in mixed mode (WPA+WPA2) cases to work around issues with Windows
7. This workaround was lost in commit
d7a15d5953 ('WPS: Indicate current AP
settings in M7 in unconfigurated state') that fixed unconfigured state
values in AP Settings, but did not take into account the earlier
workaround for mixed mode.

Re-introduce filtering of Authentication/Encryption Type attributes for
M7 based on the current AP configuration. In other words, merge those
two earlier commits together to include both the earlier workaround the
newer fix.

In addition, add newer version (GnuTLS 3.0.18 and newer) to fetch client

Bob Copeland f3b8ad4d78 SAE: Implement retransmission timer
Add the t0 retransmission timer as specified by IEEE Std 802.11-2012,
11.3.8.4. This makes SAE much more likely to succeed in the case of lost
frames.

Bob Copeland a206e2a175 SAE: Centralize function for sending initial COMMIT
When performing SAE authentication in mesh, one station may
initiate authentication by sending a COMMIT as soon as a peer
candidate is discovered. Previously we did this in mesh_rsn.c,
but this left some of the state initialization in a different
part of the code from the rest of the state machine, and we may
need to add other initializations here in the future, so move
that to a more central function.

Imre Vadasz 28c91ee124 bsd: Fix parsing of ieee80211req_scan_result on FreeBSD and DragonFly
On FreeBSD and DragonFly BSD, we additionally need to skip the
isr_meshid_len bytes of the MESH ID, to get the correct address for
copying the IE data.

The isr_meshid_len field was added in the FreeBSD svn revision r195618
in 2009, so I don't think we need to check the FreeBSD version here.

Jouni Malinen a156ffda61 Add support for testing memory allocation failures
The new control interface command TEST_ALLOC_FAIL and GET_ALLOC_FAIL can
now be used to trigger memory allocation failures for testing purposes.
TEST_ALLOC_FAIL sets a failure conditions with
<count>:func[;func][;func]... string and GET_ALLOC_FAIL returns the
current state using the same format. Whenever an allocation is made with
a matching backtrace of calling functions, the count is decremented by
one and once zero is reached, the allocation is forced to fail.

Function names can be prefixed with either '=' or '?' to get different
matching behavior. '=' requires this specific function to be the next
one in the backtrace (i.e., do not skip any other functions in the list
which is the default behavior). '?' allows the function to be optionally
present in the backtrace.

Jouni Malinen 3d2e2d5d63 trace: Fix compiler warning on 32-bit builds with bfd support
With CONFIG_WPA_TRACE_BFD, the type cast from void* to integer was
generating a compiler warning due to the target integer being larger in
size in case of 32-bit builds. Type case to bfd_hostptr_t instead of
directly to bfd_vma to avoid this.
