The driver vtables are read-only structures. This patch declares them as
'const' allowing the compiler to (optionally) put them in the RELRO
section. RELRO pages may be marked as read-only by the linker after
the relocations have been done ensuring that they aren't inadvertently
or maliciously altered at runtime.
Added the explicit support for auth NONE.
It needs to be added in all drivers/*/gprs-context.c atoms.
This method is already supported by all atoms that support
authentication (ie, all but Sierra' swmodem driver).
The behavior is left unchanged in case of inconsistent parameters:
if username is empty, then fallback to auth NONE.
Apparently it's not legal to create a QMI service multiple times for
a device. I've been testing with a Quectel EC21 and here it works fine
to do so, but the general case would require "shared" services across
atoms.
This patch switches the users of the NAS and WDS services over to using
a "shared" service instead of each instatiating their own instance.
There are three principal ways for a context to become disconnected:
i) deactivate_primary() is called
ii) the network registration is lost and the context is cleaned up
via _detach_shutdown() (via release_all_contexts())
iii) the network decides to disconnect the context
We need to watch the packet status in order to detect case iii). For
case i) and ii), stop_net will be called, the pkt_handle will be
cleared, and subsequent packet status notifications be ignored.
This patch makes it so that the packet status "disconnected" event
is only propagated when the pkt_handle has not been cleared, indicating
an unrequested disconnection.
This should fix a race reported by Christophe Ronco whereby the packet
status disconnect notification is called between activate_primary
(start_net) and it's callback (start_net_cb).
The detach_shutdown method is invoked to unconditionally release
an active context. For QMI, this is equivalent to a call to
deactivate_primary.
This patch makes the callback to deactivate_primary optional and
implements detach_shutdown to simply call it. When there is no
callback, the stop_net callback notifies ofono about the context
release via an asynchronous ofono_gprs_context_deactivated() call.
For LTE networks, a default bearer is automatically activated when
the modem registers to the network. QMI modems, however, do not
automatically enable the network interface just because the bearer
exists; a call to "start network" needs to be made in order to
get the packet handle before get_settings will return any data and
the network interface can be configured.
This patch makes read_settings call "start network" in order to
enable the interface for the default bearer. No new bearer will
be created with this call and the settings for the bearer will come
from the default profile, irregardless of what parameters are passed
to the "start network" method.
For LTE, a context is created automatically when the modem registers
to the network. The read_settings function is called for these
automatic contexts to get their configuration.
The GPRS context needs to be configured with connection parameters when
the bearer has been established. This was only partially implemented, so
this patch adds additional parameters to those passed to the context.
During gprs-context driver probe function, check kernel device driver
data format and modem low level data format.
If they are different, align kernel device driver data format on
modem low level data format.
If an error occurs during this process, continue probing without error.
This is inspired by what is done in qmicli and qmi-network (package
libqmi).
