The __str__ function assumed station mode which throws an exception
if the device is in AP mode. Fix this as well as print out the mode
the device is in.
This API optimizes scanning to run tests quickly by only scanning
the frequencies which hostapd is using. But if a test doesn't use
hostapd this API raises an uncaught exception.
Check if hostapd is being used, and if not just do a full scan.
The key descriptor version was hard coded to HMAC_SHA1_AES which
is correct when using IE_RSN_AKM_SUITE_PSK + CCMP. ap.c hard
codes the PSK AKM but still uses wiphy to select the cipher. In
theory there could be hardware that only supports TKIP which
would then make IWD non-compliant since a different key descriptor
version should be used with PSK + TKIP (HMAC_MD5_ARC4).
Now use a helper to sort out which key descriptor should be used
given the AKM and cipher suite.
Similarly to l_netconfig track whether IWD's netconfig is active (from
the moment of netconfig_configure() till netconfig_reset()) using a
"started" flag and avoid handling or emitting any events after "started"
is cleared.
This fixes an occasional issue with the Netconfig Agent backend where
station would reset netconfig, netconfig would issue DBus calls to clear
addresses and routes, station would go into DISCONNECTING, perhaps
finish and go into DISCONNECTED and after a while the DBus calls would
come back with an error which would cause a NETCONFIG_EVENT_FAILED
causing station to call netdev_disconnct() for a second time and
transition to and get stuck in DISCONNECTING.
Add an additional optional PairwiseCipher property on
net.connman.iwd.StationDiagnostic interface that will hold the current
pairwise cipher in use for the connection.
Both CMD_ASSOCIATE and CMD_CONNECT paths were using very similar code to
build RSN specific attributes. Use a common function to build these
attributes to cut down on duplicated code.
While here, also start using ie_rsn_cipher_suite_to_cipher instead of
assuming that the pairwise / group ciphers can only be CCMP or TKIP.
Instead of copy-pasting the same basic operation (memcpy & assignment),
use a goto and a common path instead. This should also make it easier
for the compiler to optimize this function.
Commit c7640f8346 was meant to fix a sign compare warning
in clang because NLMSG_NEXT internally compares the length
with nlmsghdr->nlmsg_len which is a u32. The problem is the
NLMSG_NEXT can underflow an unsigned value, hence why it
expects an int type to be passed in.
To work around this we can instead pass a larger sized
int64_t which the compiler allows since it can upgrade the
unsigned nlmsghdr->nlmsg_len. There is no underflow risk
with an int64_t either because the buffer used is much
smaller than what can fit in an int64_t.

In nearly all cases the auto-line breaks can be on spaces in the
string. The only exception (so far) is DPP which displays a very
long URI without any spaces. When this is displayed a single
character was lost on each break. This was due to the current line
being NULL terminated prior to the next line string being returned.
To handle both cases the next line is copied prior to terminating
the current line. The offsets were modified slightly so the line
will be broken *after* the space, not on the space. This leaves
the space at the end of the current line which is invisible to the
user but allows the no-space case to also work without loss of
the last character (since that last character is where the space
normally would be).
Each color escape is tracked and the new_width is adjusted
accordingly. But if the color escape comes after a space which breaks
the line, the adjusted width ends up being too long since that escape
sequence isn't appearing on the current line. This causes the next
column to be shifted over.
The old 'max' parameter was being used both as an input and output
parameter which was confusing. Instead have next_line take the
column width as input, and output a new width which includes any
color escapes and wide characters.
In theory any input to this function should have valid utf-8 but
just in case the strings should be validated. This removes the
need to check the return of l_utf8_get_codepoint which is useful
since there is no graceful failure path at this point.
The known frequency list may include frequencies that once were
allowed but are now disabled due to regulatory restrictions. Don't
include these frequencies in the roam scan.
The utf-8 bytes were being counted as normal ascii so the
width maximum was not being increased to include
non-printable bytes like it is for color escape sequences.
This lead to the row not printing enough characters which
effected the text further down the line.
Fix this by increasing 'max' when non-codepoint utf-8
characters are found.
This test was taking about 5 minutes to run, specifically
the requested scan test. One slight optimization is to
remove the duplicate hidden network, since there is no
need for two. In addition the requested scan test was
changed so it does not periodic scan and only issues a dbus
scan.
The CI was sometimes taking ~10-15 minutes to run just this
test. This is likely due to the test having 7 radios and
which is a lot of beacons/probes to process.
Disabling the unused hostapd instances drops the runtime down
to about 1 minute.
