This can be used to provide more control to upper layers on network
blocks generated as part of Interworking network selection.
INTERWORKING_ADD_NETWORK behaves otherwise identically to
INTERWORKING_CONNECT, but it does not request a new connection after
having added the network block and it returns the network id of the
added network.
INTERWORKING_ADD_NETWORK followed by REASSOCIATE would behave more or
less identically to INTERWORKING_CONNECT, but this allows the created
network profile to be modified, if desired, and/or stored externally.
SELECT_NETWORK can also be used with the network id returned from
INTERWORKING_ADD_NETWORK to enforce that specific network profile to be
used for the next connection (though, it should be noted that this
behavior may not meet all Hotspot 2.0 requirements if there were other
enabled networks that could have higher priority).

Commit b31be3a0fd ('P2P: Add automatic GO
Negotiation vs. join-a-group selection') added this P2P_CONNECT 'auto'
parameter, but did not update any documentation on it.
Signed-off-by: Jouni Malinen <j@w1.fi>
If a separate P2P group interface was used, P2P_CONNECT-auto fallback to
GO Negotiation could result in use of freed memory and segmentation
fault. This happened in cases where the peer GO was found in some old
scans, but not in the first scan triggered by the P2P_CONNECT-auto
command ("P2P: Peer was found running GO in older scan -> try to join
the group" shows up in the debug log). In addition, the GO would still
need to reply to PD Request to allow this code path to be triggered.
When five scans for the GO were completed in this sequence, the P2P
group interface was removed as part of falling back to GO Negotiation.
However, that ended up dereferencing the freed wpa_s instance at the end
of scan event processing. Fix this by reordering code a bit and breaking
out from EVENT_SCAN_RESULTS processing if the interface could have been
removed.

When SAE authentication fails, wpa_supplicant retries four times. If all
the retries result in failure, SAE state machine enters BLOCKED state.
Once it enters this state, wpa_supplicant doesn't retry connection. This
commit allow connection retries even if the state machine entered
BLOCKED state.
There could be an opinion "Is this patch needed? User could know the SAE
state machine is in the BLOCKED mode by MESH-SAE-AUTH-BLOCKED event.
Then user can retry connection. By user action, SAE state machine can
change the state from BLOCKED to another.". Yes, this is a true at the

When noise floor measurements are not available, compute SNR
using default values for the noise floor. This helps steer us
towards 5 GHz BSSes in high signal strength environments.
In more detail...
Existing code prefers a 5 GHz BSS when the 5 GHz BSS's signal
strength is "close" to that of the 2.4 GHz BSS, or when both SNRs
are large. However, the mwifiex driver does not provide noise
floor measurements, so we can't compute SNRs.
Because mwifiex doesn't provide NF measurements, the "large SNR"
code wasn't effective. By using default values for the noise floor,
we can again compute SNRs, and decide that the SNR is high enough
that we shouldn't worry about the exact difference in SNR.
The default noise floor values (one for 2.4 GHz, and one for 5 GHz)
were chosen by measurement in a noisy environment, so they should be
conservative.
Note that while this patch is motivated by mwifiex, it affects
ath9k as well. Although ath9k provides noise floor measurements
in general, it will sometimes fail to provide a measurement for
one or more specific channels.
As a result of this patch, we'll always compare BSSes based on SNR
(either measured or estimated), rather than sometimes comparing
based on signal strength. ("Always" assumes that the
WPA_SCAN_LEVEL_DBM flag is set. It is for mwifiex and ath9k.)
While there:
- fix a whitespace issue (spaces -> tab)
- clean up existing comments
- update dump_scan_res to indicate whether the noise floor is
measured, or default

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).

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.

retry behavior to be disabled. This will make wpa_supplicant abort
authentication attempt on E=691 regardless of whether the server allows

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.

Currently, there is a race in open mesh networks where mesh STA A
receives a beacon from B and sends a peering open frame to initiate
peering. STA B, having not yet received a beacon from A and thus
created the corresponding station entry, will ignore all such open
frames. If the beacon interval is sufficiently long then peering
will not succeed as a result.
In fact B can simply create the station entry when the popen is
received, as is done in Linux's in-kernel MPM, avoiding the issue.

Previously, we would only free the station entry if a peering close
frame was received (freeing the station entry causes the kernel to
start sending peer candidate events again when suitable beacons are
received, triggering peering or authentication to restart).
The end result is the same in any case regardless of close reason:
if we leave holding state then peering has started again, so go
ahead and remove the station in all cases.

For Interworking connection to work, the SSID of the selected BSS needs

earlier scan with that AP has shown a hidden SSID configuration (e.g.,
when running hwsim test cases, but at least in theory, this could happen
with real use cases as well). When that happened, the incorrect BSS
entry may not have included RSN configuration and as such, it would get

not, try to find another BSS entry matching the same BSSID and use that,

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.

pretty ugly extension. Replace these with a cleaner way of passing the
separating string (e.g., "Networks") from the caller and returning the
requested item.
In addition, there is no need to allocate the returned item separately,
so use a single allocation and a pointer to that allocated memory. This
will make it easier for callers to have to free only a single
allocation. This is also fixing a memory leak in P2P invitation

It looks like both gcc and clang optimize the (entry.type != foo ||
entry.array_type != bar) in a way that ends up evaluating the second
condition even when the first one results in 0. While this is not really
what the C language requirements on short-circuit evaluation require,
the compiler likely assumes this can have no side effects and with both
type and array_type being comparable in a single 64-bit operation, this
can clearly be a bit more efficient. While the code behaves same in both
cases, valgrind does warn about use of uninitialized memory when the
second condition is evaluated (entry.array_type is not initialized if
entry.type != DBUS_TYPE_ARRAY).
To keep valgrind logs cleaner, initialize entry.array_type to
DBUS_TYPE_INVALID so that these compiler optimizations do not result in
reading uninitialized memory.

Replace with 'num > left / 5' to avoid false reports. (CID 68117)

This reduced number of unnecessarily duplicated driver interface
callback functions for sending Action frames by using the more generic
send_action() instead of FT specific send_ft_action().

This extends the previously used WFD_SUBELEM_SET/GET <subelem id> design
to allow special "all" value to be used as an id to indicate that all
WFD subelements are to be set/get. This uses similar interface as was
previously added over D-Bus.

There is no point in flooding the log with WARNING or ERROR level
messages if WMM-AC related Action frames are ignored in cases where they
were not expected. In addition, WARNING/ERROR should not really be used
in cases an invalid frame is dropped especially if this is not related
to a security setup since external devices could otherwise generate log
entries.

The previous version was somewhat too complex for some static analyzers.
Use local variables for the extracted length fields and explicitly
compare these against the remaining buffer length. (CID 68121)

Derive rRK and rIK on EAP peer if ERP is enabled. The new wpa_supplicant
network configuration parameter erp=1 can now be used to configure the
EAP peer to derive EMSK, rRK, and rIK at the successful completion of an
EAP authentication method. This functionality is not included in the
default build and can be enabled with CONFIG_ERP=y.
If EAP authenticator indicates support for re-authentication protocol,
initiate this with EAP-Initiate/Re-auth and complete protocol when
receiving EAP-Finish/Re-auth.

This change creates 'LIST_NETWORK LAST_ID=x' form to allow
retrieval of all networks saved in the system. Without this form,
only first few (whatever fills in first 4096 bytes) can be
retrieved.

wpa_bss_in_use() used to determine that a BSS with BSSID of
00:00:00:00:00:00 is in use in almost every case since either
wpa_s->bssid or wpa_s->pending_bssid was likely to be cleared. This
could result in a corner case of a BSS entry remaining in the BSS table
indefinitely if one was added there with a (likely bogus) address of
00:00:00:00:00:00. Fix this by ignore wpa_s->bssid and
wpa_s->pending_bssid if the BSSID in the BSS table entry is
00:00:00:00:00:00.
In theory, that address is a valid BSSID, but it is unlikely to be used
in any production AP, so the potential expiration of a BSS entry with
that address during a connection attempt would not be a concern
(especially when a new scan would be enough to recover from that).

Externally triggered scan could result in a new radio work item getting
started even when external radio work was in progress. Delay such start
until the external work is completed.

It was possible for the current network profile to be deleted when
merging duplicated WPS credentials. However, this did not clear
wpa_s->current_ssid and it was possible for something else to end up
dereferencing that pointer to now freed memory. This could be hit, e.g.,
with ap_wps_mixed_cred. Fix this by clearing current_ssid also in this
code path similarly to other cases of network block getting removed.

The mesh group addition was designed to use wpa_s->connect_without_scan
to skip a scan. That path was skipped if wpa_supplicant_fast_associate()
allowed previous scan results to be used. This could result in undesired
double-initialization attempt for the mesh interface. Avoid this by not
using wpa_supplicant_fast_associate() when wpa_s->connect_without_scan
is set.

It is possible that these location ended up getting called before mesh
startup operations had been completed and that could result in
dereferencing NULL pointers. Address those error cases by verifying that
the needed parameters are available before using them.
