The offchannel priority was also changed to zero, which matches the
priority of frames. Currently there should be no interaction between
offchannel and connect (previous offchannel priority).
Periodic scans were handled specially where they were only
started if no other requests were pending in the scan queue.
This is fine, and what we want, but this can actually be
handled automatically by nature of the wiphy work queue rather
than needing to check the request queue explicitly.
Instead we can insert periodic scans at a lower priority than
other scans. This puts them at the end of the work queue, as
well as allows future requests to jump ahead if a periodic scan
has not yet started.
Eventually, once all pending scans are done, the peridoic scan
may begin. This is no different than the preivous behavior and
avoids the need for any special checks once scan requests
complete.
One check was added to address the problem of the periodic scan
timer firing before the scan could even start. Currently this
happened to be handled fine in scan_periodic_queue, as it checks
the queue length. Since this check was removed we must see check
for this condition inside scan_periodic_timeout.
This adds a priority argument to scan_common rather than hard
coding it when inserting the work item and uses the newly
defined wiphy priority for scanning.
Work priority was never explicitly defined anywhere, and a module
using wiphy_radio_work APIs needed to ensure it was not inserting
at a priority that would interfere with other work.
Now all the types of work have been defined with their own priority
and future priorities can easily be added before, after, or in
between existing priorities.
- Mostly problems with whitespace:
- Use of spaces instead of tabs
- Stray spaces before closing ')
- Missing spaces
- Missing 'void' from function declarations & definitions that
take no arguments.
- Wrong indentation level
When this attribute is included, the initiator is requesting all
future frames be sent on this channel. There is no reason for a
configurator to act on this attribute (at least for now) so the
request frame will be dropped in this case. Enrollees will act
on it by switching to the new channel and sending the authentication
response.
While connected the driver ends up choosing quite small ROC
durations leading to excessive calls to ROC. This also will
negatively effect any wireless performance for the current
network and possibly lead to missed DPP frames.
Currently the enrollee relied on autoconnect to handle connecting
to the newly configured network. This usually resulted in poor
performance since periodic scans are done at large intervals apart.
Instead first check if the newly configured network is already
in IWD's network queue. If so it can be connected to immediately.
If not, a full scan must be done and results given to station.
With better JSON support the configuration request object
can now be fully parsed. As stated in the previous comment
there really isn't much use from the configurator side apart
from verifying mandatory values are included.
This patch also modifies the configuration result to handle
sending non 'OK' status codes in case of JSON parsing errors.
json_iter_parse is only meant to work on objects while
json_iter_next is only meant to work on arrays.
This adds checks in both APIs to ensure they aren't being
used incorrectly.
Arrays can now be parsed using the JSON_ARRAY type (stored in
a struct json_iter) then iterated using json_iter_next. When
iterating the type can be checked with json_iter_get_type. For
each iteration the value can be obtained using any of the type
getters (int/uint/boolean/null).
This adds support for boolean, (unsigned) integers, and
null types. JSON_PRIMITIVE should be used as the type when
parsing and the value should be struct json_iter.
Once parsed the actual value can be obtained using one of
the primitive getters. If the type does not match they will
return false.
If using JSON_OPTIONAL with JSON_PRIMITIVE the resulting
iterator can be checked with json_iter_is_valid. If false
the key/value was not found or the type was not matching.
First, this was renamed to 'count_tokens_in_container' to be
more general purpose (i.e. include future array counting).
The way the tokens are counted also changed to be more intuitive.
While the previous way was correct, it was somewhat convoluted in
how it worked (finding the next parent of the objects parent).
Instead we can use the container token itself as the parent and
begin counting tokens. When we find a token with a parent index
less than the target we have reached the end of this container.
This also works for nested containers, including arrays since we
no longer rely on a key (which an array element would not have).
For example::
{
"first":{"foo":"bar"},
"second":{"foo2":"bar2"}
}
index 0 <overall object>
index 1 "first" with parent 0
index 2 {"foo":"bar"} with parent 1
Counting tokens inside "first"'s object we have:
index 3 "foo" with parent 2
index 4 "bar" with parent 3
If we continue counting we reach:
index 5 "second" with parent 0
This terminates the counting loop since the parent index is
less than '2' (the index of {"foo":"bar"} object).

Some wpa_cli utilities return some result which isn't possible to
get with wait_for_event unless you know what the result will be.
This adds wait_for_result which just returns the first event that
comes in.
