The autoconf macros AX_COMPILER_FLAGS_{CFLAGS|GIR|LDFLAGS} test
for compiler and linker support of various flags, and add the flags to
the generated output.

If the command-line option '--enable-compile-warnings' is specified to
'configure', a number of additional warning options is also added to the
output. This is the default.

This update requires the presence of the GNU autoconf-archive in the
system.

Aleksander Morgado 4bfd955e64 auth-provider: fix reference count in manager and modem objects
The auth provider is now a singleton (since 20ab6550), one single
object that lives throughout the whole program execution, and so we
don't need to keep our own full references around. This fix makes
sure we don't attempt to unref a full auth provider reference we
don't own.

Aleksander Morgado 2406a5519f charsets: fix handling of 0x00 bytes at the end of GSM encoded strings
When a GSM-7 encoded string is packed, the process of packing the
septets into bytes may end up with one last byte holding the last bit
of the last septet. When this situation happens, the last byte will
end up with the 7 remaining bits set to 0.

When this packed string is unpacked, the logic to unpack will unpack
those last 7 bits as an additional septet, with the value 0x00.

The 0x00 value encoded in GSM-7 is the '@' character, EXCEPT when this
character is found at the end of the string, in which case the value
should be considered as NUL and trigger the end of string already.

So, fix the conversion logic between GSM-7 and UTF-8, so that whenever
we find the 0x00 character at the end of the string, we ignore it
instead of adding a bogus '@' trailing character.

This commit fixes the "/MM/charsets/gsm7/default-chars" unit test
after having it updated to perform the full conversion cycle:
   UTF-8 -> packed GSM7 -> UTF-8

Aleksander Morgado 20ab6550fb auth-provider: refactor and simplify
The auth provider setup is a bit over-engineered. Simplify it by
making a single MMAuthProvider object that may or may not use polkit,
depending on configure options. This object is also setup as a
singleton object using the helper MM_DEFINE_SINGLETON_GETTER().

cleanups.

dispose(), as there is no guarantee at all that the port objects will
exist in the MMBaseModem by the time finalize() is run.

Aleksander Morgado 246fe710b7 iface-modem-location: fix big memleak when processing location updates
The GVariants that we obtain during the processing of the "previous"
dictionary with g_variant_iter_next() are full references, while the
GVariants that we obtain processing the input MMLocationXX objects are
floating references.

The code was working well with the floating references only, as it was
assumed that g_variant_builder_add() would take ownership of them as
full references; but when the GVariant came from the
g_variant_iter_next() processing, g_variant_builder_add() would take a
full new extra reference, triggering the memory leak.

Fix this, by making sure that we always work with full GVariant
references in all cases, converting the floating ones with
g_variant_ref_sink() and making sure we explicitly unref them after
g_variant_builder_add().

Aleksander Morgado fbc1e3f89e device: don't reprobe if device is gone
When a QMI/MBIM device is unplugged, we first get the notification
from the proxy that the communication is broken, and then we get the
kernel event reporting that the cdc-wdm port is gone.

If we reprobe the device as soon as the proxy notifies us that the
communication is broken, we would end up trying to reprobe the cdc-wdm
port when it's already gone, and we end up trying to create a modem
object when we shouldn't:

Fix this by delaying the reprobing attempt some time, and make sure we
cancel the reprobing if the device detects that all ports are gone.

Aleksander Morgado 941879b43a device: keep reference to object manager server
Instead of having the reference to the object manager server only
while the modem is exported, just keep a reference for as long as the
device object exists. This will make it easier to handle reprobing
logic.

Aleksander Morgado debec6f650 iface-modem-3gpp: forced registration is not state
The request for forced registration is an implementation detail of
mm_iface_modem_3gpp_register_in_network(), not part of any state to

Aleksander Morgado 88983fd157 cinterion: use common re-registration logic when needed
If the modem requires +COPS re-registration after setting modes,
use the common logic provided by the 3GPP interface, which
already knows e.g. whether the registration was automatic or the
actual requested operator id in case of being manual.

Aleksander Morgado a1966222e9 ublox: use common re-registration logic when needed
If the modem requires +COPS re-registration after setting bands or
modes, use the common logic provided by the 3GPP interface, which
already knows e.g. whether the registration was automatic or the
actual requested operator id in case of being manual.

This will also make the u-blox plugin use the common +COPS set command
implemented in the broadband modem object, which has the fallback to
use the MCCMNC encoded in the current charset if needed.

Aleksander Morgado 4862e42c86 iface-modem-3gpp: fix manual re-registration to the same operator
We should not assume that a manual registration request to a given
operator is successful if the modem is already registered in that
operator, because if the registration was due to an automatic process,
we cannot make sure the modem won't roam to a different network.

We should only assume that a manual registration is not needed to be
relaunched if the modem is already registered in the requested network
AND if the registration process was manual (i.e. we asked the modem to
lock into a given network).

Aleksander Morgado cf9afc3220 broadband-modem: retry +COPS=1,2,<mccmnc> with current charset
If the modem (e.g. u-blox LARA) returns a "Not supported" error when
attempting to run +COPS=1,2,<mccmnc> with the MCCMNC encoded in ASCII
(and current charset is different, e.g. UCS2), then attempt to re-run
the same command with the MCCMNC encoded in the explicit current
charset.

Aleksander Morgado baa68f5a4a libmm-glib,simple-connect-properties: cleaner error handling
If processing a key-value pair as a bearer property fails, we need to
know if it failed due to the key being unknown or due to some other
reason (e.g. failure parsing value of a known key).

We'll only try with the Simple.Connect properties if the key is
reported as unknown in the bearer properties.

This will help us better identify errors if e.g. an invalid value is
given to a known key. E.g. "yes" was invalid for allow-roaming here:

    daemon.notice netifd: wan (30476): simple connect=apn=internet,ip-type=ipv4,allow-roaming=yes
    daemon.notice netifd: wan (30476): Error parsing connect string: 'Invalid properties string, unexpected key 'allow-roaming''
2020-01-06 14:46:36 +01:00
Aleksander Morgado 15e8a78a15 libmm-glib,common-helpers: allow yes/no as booleans in string
E.g. so that the settings passed on Simple.Connect() or
Bearer.Connect() are parsed correctly from the user string:

  daemon.notice netifd: wan (30476): simple connect=apn=internet,ip-type=ipv4,allow-roaming=yes
  daemon.notice netifd: wan (30476): Error parsing connect string:
  'Invalid properties string, unexpected key 'allow-roaming''

This also goes inline with e.g. the --create-bearer help in the man
page that suggests using yes/no for the allow-roaming setting.
