There are a large number of files in the tree that define _GNU_SOURCE
despite not actually using features hidden behind this flag. This patch
removes all these definitions in one fell swoop...
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.
The U-Blox documentation specifies the following:
* get interface ip and dns from +CGDCONTRDP
* get gw ip and netmask from +UIPADDR
However, different firmware versions have different befaviour:
* On newer firmware, +UIPADDR returns error. But it's possible to configure
gateway ip == ipterface ip (read from CGDCONTRDP).
* On older firmware, we can actually use the commands specified in the
docs.
This patch runs +CGDCONTRDP, configures everything and then tries to run
+UIPADDR. In that works, reconfigures gw ip and netmask.
For now the driver works only with bridged mode for 2G/3G.
Once it activates the context it reads the ip, netmask,
gw, dns and sets them in the context settings.
