This is a minimal wrapper around jsmn.h to make things a bit easier
for iterating through a JSON object.
To use, first parse the JSON and create a contents object using
json_contents_new(). This object can then be used to initialize a
json_iter object using json_iter_init().
The json_iter object can then be parsed with json_iter_parse by
passing in JSON_MANDATORY/JSON_OPTIONAL arguments. Currently only
JSON_STRING and JSON_OBJECT types are supported. Any JSON_MANDATORY
values that are not found will result in an error.
If a JSON_OPTIONAL string is not found, the pointer will be NULL.
If a JSON_OPTIONAL object is not found, this iterator will be
initialized but 'start' will be -1. This can be checked with a
convenience macro json_object_not_found();
Static analysis was not happy since this return can be negative and
it was being fed into an unsigned argument. In reality this cannot
happen since the key buffer is always set to the maximum size supported
by any curves.
This module provides a convenient wrapper around both
CMD_[CANCEL_]_REMAIN_ON_CHANNEL APIs.
Certain protocols require going offchannel to send frames, and/or
wait for a response. The frame-xchg module somewhat does this but
has some limitations. For example you cannot just go offchannel;
an initial frame must be sent out to start the procedure. In addition
frame-xchg does not work for broadcasts since it expects an ACK.
This module is much simpler and only handles going offchannel for
a duration. During this time frames may be sent or received. After
the duration the caller will get a callback and any included error
if there was one. Any offchannel request can be cancelled prior to
the duration expriring if the offchannel work has finished early.
Make sure we wipe the leases file both for server and client, so that
dhclient doesn't try to re-use leases from previous tests (should really
happen) and waste time waiting for a reply. Extend the timeout from 1s
to 5s, sometimes it takes dhclient 1s just to start. Disable verbose
mode if not needed to avoid dhclient stalling if the pipe is not being
read.
The disconnect event handler was mistakenly bailing out if FT or
reassociation was going on. This was done because a disconnect
event is sent by the kernel when CMD_AUTH/CMD_ASSOC is used.
The problem is an AP could also disconnect IWD which should never
be ignored.
To fix this always parse the disconnect event and, if issued by
the AP, always notify watchers of the disconnect.
Passing *args, **kwargs into StationDebug ended up initializing the
class with Station properties since devices can be initialized from
existing property dictionaries. Since the object path is all
StationDebug needs, pass args[0] instead.
LLD 13 and GNU ld 2.37 support -z start-stop-gc which allows garbage
collection of C identifier name sections despite the __start_/__stop_
references. GNU ld before 2015-10 had the behavior as well. Simply set
the retain attribute so that GCC 11 (if configure-time binutils is 2.36
or newer)/Clang 13 will set the SHF_GNU_RETAIN section attribute to
prevent garbage collection.
Without the patch, there are linker errors with -z start-stop-gc
(LLD default) when -Wl,--gc-sections is used:
```
ld.lld: error: undefined symbol: __start___eap
>>> referenced by eap.c
>>> src/eap.o:(eap_init)
```
The remain attribute will not be needed if the metadata sections are
referenced by code directly.
Document the new API that clients can use to get notified of new network
configuration and be responsible for committing it to the netdev, the
resolver, etc.
On some systems the default radvd pid file location is not accessible.
Specify it to be under /tmp instead.
While there, enable full radvd debug output so it is logged when
test-runner is invoked with the --log option.
ap.c has been mostly careful to call the event handler at the end of any
externally called function to allow methods like ap_free() to be called
within the handler, but that isn't enough. For example in
ap_del_station we may end up emitting two events: STATION_REMOVED and
DHCP_LEASE_EXPIRED. Use a slightly more complicated mechanism to
explicitly guard ap_free calls inside the event handler.
To make it easier, simplify cleanup in ap_assoc_reassoc with the use of
_auto_.
In ap_del_station reorder the actions to send the STATION_REMOVED event
first as the DHCP_LEASE_EXPIRED is a consequence of the former and it
makes sense for the handler to react to it first.
src/eap.c: In function 'eap_rx_packet':
src/eap.c:419:50: error: 'vendor_type' may be used uninitialized in this function [-Werror=maybe-uninitialized]
419 | (type == EAP_TYPE_EXPANDED && vendor_id == (id) && vendor_type == (t))
| ^~
src/eap.c:430:11: note: 'vendor_type' was declared here
430 | uint32_t vendor_type;
It isn't clear why GCC complains about vendor_type, but not vendor_id.
But in all cases if type == EAP_TYPE_EXPANDED, then vendor_type and
vendor_id are set. Silence this spurious warning.
