Both ell/shared and ell/internal targets first create the ell/
directory within IWD. This apparently was just luck that one of
these always finished first in parallel builds. On my system at
least when building using dpkg-buildpackage IWD fails to build
due to the ell/ directory missing. From the logs it appears that
both the shared/internal targets were started but didn't complete
(or at least create the directory) before the ell/ell.h target:
make[1]: Entering directory '/home/jprestwood/tmp/iwd'
/usr/bin/mkdir -p ell
/usr/bin/mkdir -p ell
echo -n > ell/ell.h
/usr/bin/mkdir -p src
/bin/bash: line 1: ell/ell.h: No such file or directory
make[1]: *** [Makefile:4028: ell/ell.h] Error 1
Creating the ell/ directory within the ell/ell.h target solve
the issue. For reference this is the configure command dpkg
is using:
./configure --build=x86_64-linux-gnu \
--prefix=/usr \
--includedir=/usr/include \
--mandir=/usr/share/man \
--infodir=/usr/share/info \
--sysconfdir=/etc \
--localstatedir=/var \
--disable-option-checking \
--disable-silent-rules \
--libdir=/usr/lib/x86_64-linux-gnu \
--runstatedir=/run \
--disable-maintainer-mode \
--disable-dependency-tracking \
--enable-tools \
--enable-dbus-policy
The StartConfigurator() call was left out since there would be no
functional difference to the user in iwctl. Its expected that
human users of the shared code API provide the code/id ahead of
time, i.e. use ConfigureEnrollee/StartEnrollee.
This allows generating code and test coverage reports using lcov &
genhtml. Useful for understanding how much of the codebase is currently
covered by unit and autotests.
Add netconfig-commit.c whose main method, netconfig_commit actually sets
the configuration obtained by l_netconfig to the system netdev,
specifically it sets local addresses on the interface, adds routes to the
routing table, sets DNS related data and may add entries to the neighbor
cache. netconfig-commit.c uses a backend-ops type structure to allow
for switching backends. In this commit there's only a default backend
that uses l_netconfig_rtnl_apply() and a struct resolve object to write
the configuration.
netconfig_gateway_to_arp is moved from netconfig.c to netconfig-commit.c
(and renamed.) The struct netconfig definition is moved to netconfig.h
so that both files can access the settings stored in the struct.
Drop all the struct netconfig members where we were keeping the parsed
netconfig settings and add a struct l_netconfig object. In
netconfig_load_settings load all of the settings once parsed directly
into the l_netconfig object. Only preserve the mdns configuration and
save some boolean values needed to properly handle static configuration
and FILS. Update functions to use the new set of struct netconfig
members.
These booleans mirroring the l_netconfig state could be replaced by
adding l_netconfig getters for settings which currently only have
setters.
This tool will decrypt an IWD network profile which was previously
encrypted using a systemd provided key. Either a text passphrase
can be provided (--pass) or a file containing the secret (--file).
This can be useful for debugging, or recovering an encrypted
profile after enabling SystemdEncrypt.
Some users don't like the idea of storing network credentials in
plaintext on the file system. This patch implements an option to
encrypt such profiles using a secret key. The origin of the key can in
theory be anything, but would typically be provided by systemd via
'LoadEncryptedCredential' setting in the iwd unit file.
The encryption operates on the entire [Security] group as well as all
embedded groups. Once encrypted the [Security] group will be replaced
with two key/values:
EncryptedSalt - A random string of bytes used for the encryption
EncryptedSecurity - A string of bytes containing the encrypted
[Security] group, as well as all embedded groups.
After the profile has been encrypted these values should not be
modified. Note that any values added to [Security] after encryption
has no effect. Once the profile is encrypted there is no way to modify
[Security] without manually decrypting first, or just re-creating it
entirely which effectively treated a 'new' profile.
The encryption/decryption is done using AES-SIV with a salt value and
the network SSID as the IV.
Once a key is set any profiles opened will automatically be encrypted
and re-written to disk. Modules using network_storage_open will be
provided the decrypted profile, and will be unaware it was ever
encrypted in the first place. Similarly when network_storage_sync is
called the profile will by automatically encrypted and written to disk
without the caller needing to do anything special.
A few private storage.c helpers were added to serve several purposes:
storage_init/exit():
This sets/cleans up the encryption key direct from systemd then uses
extract and expand to create a new fixed length key to perform
encryption/decryption.
__storage_decrypt():
Low level API to decrypt an l_settings object using a previously set
key and the SSID/name for the network. This returns a 'changed' out
parameter signifying that the settings need to be encrypted and
re-written to disk. The purpose of exposing this is for a standalone
decryption tool which does not re-write any settings.
storage_decrypt():
Wrapper around __storage_decrypt() that handles re-writing a new
profile to disk. This was exposed in order to support hotspot profiles.
__storage_encrypt():
Encrypts an l_settings object and returns the full profile as data
ASN1 parsing will soon be required which will need some utilities in
asn1-private.h. To avoid duplication include this private header and
replace the OID's with the defined structures as well as remove the
duplicated macros.
This file is meant as a sample and contains only the most typically
changed settings. For other settings users should refer to the
iwd.config manual page.
Two commands were added:
dpp <iface> start-enrollee
dpp <iface> start-configurator
dpp <iface> stop
In addition there is support for using the qrencode utility for displaying
the QR code after DPP is started (enrollee or configurator. If qrencode is
found on the system the QR code will be displayed. Otherwise only the URI
will be printed to the console.
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();
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.
Netconfig was the only user of sysfs but now other modules will
also need it.
Adding existing API for IPv6 settings, a IPv4 and IPv6 'supports'
checker, and a setter for IPv4 settings.
The SAE unit test was written when group 19 was preferred by default for
all SAE connections. However, we have now started to prefer higher
security groups. Trick the test into using group 19 by wrapping
l_ecc_supported_ike_groups implementation to return just curve 19 as a
supported curve.
Move the band definition out of wiphy.c and into band.[ch]. This is
done to make certain utilities that depend on band information capable
of being tested from unit tests.
The band concept will most likely grow over time. For now, the only
user will be wiphy.c and unit tests, so the structures are kept public.
Add the ip-pool submodule that tracks IPv4 addresses in use on the
system for use when selecting the address for a new AP. l_rtnl_address
is used internally because if we're going to return l_rtnl_address
objects it would be misleading if we didn't fill in all of their
properties like flags etc.
For now this module serves as a helper for printing diagnostic
dictionary values. The new API (diagnostic_display) takes a
Dbus iterator which has been entered into a dictionary and
prints out each key and value. A mapping struct was defined
which maps keys to types and units. For simple cases the mapping
will consist of a dbus type character and a units string,
e.g. dBm, Kbit/s etc. For more complex printing which requires
processing the value the 'units' void* cant be set to a
function which can be custom written to handle the value.
AP mode will use the same structure for its diagnostic interface
and mostly the same dictionary keys. Apart from ConnectedBss and
Address being different, the remainder are the same so the
diagnostic_station_info to DBus dictionary conversion has been made
common so both station and AP can use it to build its diagnostic
dictionaries.
Retrieve the dependencies of readline through pkg-config (and fallback
to -lreadline) to avoid the following build failure:
