The display refresh is automatically enabled or disabled depending on
the width of the window. This allows to avoid the incorrect display on
refresh for the small windows.
Instead of calling display(""), explicitly use the sequence of
commands to force readline to properly update its internal state
and re-display the prompt.
For PSK networks we have netdev.c taking care of setting the linkmode &
operstate. For open adhoc networks, netdev.c was never involved which
resulted in linkmode & operstate never being set. Fix this by invoking
the necessary magic when a connection is established.
adhoc_reset() destroys ssid and sta_states but leaves the pointers
around, athough the adhoc_state structure is not always freed.
This causes a segfault when exiting iwd after a client has done
adhoc start and adhoc stop on a device since adhoc_reset() is called
from adhoc_sta_free although it was previously called from
adhoc_leave_cb().
The netdev_leave_adhoc() returns a negative errno on errors and zero
on success, but adhoc_dbus_stop() assumed the inverse when checking for
an error.
Also, the DBus message was not being referenced in adhoc->pending and
then adhoc_leave_cb() segfaulted attempting to dereference it.
Doing 'ad-hoc <wlan> start_open <"network name">' returned a
"No matching method found" error because start_open called
net.connman.iwd.AdHoc.Start instead of net.connman.iwd.AdHoc.StartOpen.
It seems some APs send the IGTK key in big endian format (it is a
uin16). The kernel rightly reports an -EINVAL error when iwd issues a
NEW_KEY with such a value, resulting in the connection being aborted.
Work around this by trying to detect big-endian key indexes and 'fixing'
them up.
When running test-runner as non-root the environment variables
SUDO_GID/SUDO_UID were unset, causing atoi to segfault. This replaces
atoi with strtol, and checks the existance of SUDO_GID/SUDO_UID
before trying to turn it into an integer. This patch also allows
the uid/gid to be read from the user if running as non-root.
Note: running as non-root does require the users permissions to be
setup properly. Directories and files are created when running with
logging, so if the user running test-runner does not have these
permissions the creation of these files will fail.
The configuration value of iwd_config_dir was defaulting to /etc/iwd
which, in the context of test-runner, is probably not the best idea.
The system may have a main.conf file in /etc/iwd which could cause
tests to fail or behave unexpectedly.
In addition all tests which use iwd_config_dir set it to /tmp anyways.
Because of this, the new default value will be /tmp and no tests will
even need to bother setting this.
The configuration value itself is not being removed because it may be
useful to set arbitrary paths (e.g. /etc/iwd) for example when using
the shell functionality.
This bug has been in here since OWE was written, but a similar bug also
existed in hostapd which allowed the PTK derivation to be identical.
In January 2020 hostapd fixed this bug, which now makes IWD incompatible
when using group 20 or 21.
This patch fixes the bug for IWD, so now OWE should be compatible with
recent hostapd version. This will break compatibility with old hostapd
versions which still have this bug.
If the AP only supports an AKM which requires an auth protocol
CMD_AUTHENTICATE/CMD_ASSOCIATE must be supported or else the
auth protocol cannot be run. All the auth protocols are started
assuming that the card supports these commands, but the support
was never checked when parsing supported commands.
This patch will prevent any fullMAC cards from using
SAE/FILS/OWE. This was the same behavior as before, just an
earlier failure path.
This function was intended to catch socket errors and destroy the group
but it would leak the l_io object if that happened, and if called on
ordinary shutdown it could cause a crash. Since we're now assuming
that the netlink socket operations never fail just remove it.
Only add constants for parsing the Device Information subelement as that
is the main thing we care about in P2P code. And since our own WFD IEs
will likely only need to contain the Device Information subelement, we
don't need builder utilities. We do need iterator utilities because we
may receive WFD IEs with more subelements.
In some cases a P2P peer will ACK our frame but not reply on the first
attempt, and other implementations seem to handle this by going back to
retransmitting the frame at a high rate until it gets ACKed again, at
which point they will again give the peer a longer time to tx the
response frame. Implement the same logic here by adding a
retries_on_ack parameter that takes the number of additional times we
want to restart the normal retransmit counter after we received no
response frame on the first attempt. So passing 0 maintains the
current behaviour, 1 for 1 extra attempt, etc.
In effect we may retransmit a frame about 15 * (retry_on_ack + 1) *
<in-kernel retransmit limit> times. The kernel/driver retransmits a
frame a number of times if there's no ACK (I've seen about 20 normally)
at a high frequency, if that fails we retry the whole process 15 times
inside frame-xchg.c and if we still get no ACK at any point, we give up.
If we do get an ACK, we wait for a response frame and if we don't get
that we will optionally reset the retry counter and restart the whole
thing retry_on_ack times.
