Jukka Rissanen cf063fe85b net: Rename net_is_xxx...() functions to net_xxx_is...()
Unify the function naming for various network checking functions.

For example:
     net_is_ipv6_addr_loopback() -> net_ipv6_is_addr_loopback()
     net_is_my_ipv6_maddr() -> net_ipv6_is_my_maddr()
etc.

Ulf Magnusson 1073882998 subsys: kconfig: Remove 'default n' properties and clean up a bit
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.

Remove some 'default ""' properties on string symbols too.

Also make definitions more consistent by converting some

  config FOO
  	<type>
  	prompt "foo"

definitions to a shorter form:

  config FOO
  	<type> "foo"

This shorthand works for int/hex/string symbols too, not just for bool
symbols.

Jukka Rissanen ca8b00a3cc net: if: Make interface IP configuration more flexible
Instead of always allocating both IPv6 and IPv4 address information
to every network interface, allow more fine grained address
configuration. So it is possible to have IPv6 or IPv4 only network
interfaces.

This commit introduces two new config options:
CONFIG_NET_IF_MAX_IPV4_COUNT and CONFIG_NET_IF_MAX_IPV6_COUNT
which tell how many IP address information structs are allocated
statically. At runtime when network interface is setup, it is then
possible to attach this IP address info struct to a specific
network interface. This can save considerable amount of memory
as the IP address information struct can be quite large (depends
on how many IP addresses user configures in the system).

Note that the value of CONFIG_NET_IF_MAX_IPV4_COUNT and
CONFIG_NET_IF_MAX_IPV6_COUNT should reflect the estimated number of
network interfaces in the system. So if if CONFIG_NET_IF_MAX_IPV6_COUNT
is set to 1 and there are two network interfaces that need IPv6
addresses, then the system will not be able to setup IPv6 addresses to
the second network interface in this case. This scenario might be
just fine if the second network interface is IPv4 only. The net_if.c
will print a warning during startup if mismatch about the counts and
the actual number of network interface is detected.

In case of TCP and node acting as a APP_SERVER it can have multiple

active connections exists, causing an issue.

e.g. When a node acting as a HTTP server and can support multiple
TCP connections. Let's say one of the connection is in closing
state and the rest are still in active state. net_app_ctx is
calling close (http_closed) callback of registered upper layers.
HTTP assumes all the connections are closed and unref all the

When net_app_ctx has multiple net_contexts, selecting net_context
based on dst address has some glitches.

E.g. One net_app_ctx and two net_contexts (net_ctx1, net_ctx2).
     Both net_contexts are mapped to net_app_ctx.
     When a caller looking for net_ctx (e.g. net_ctx2) with
     matching dst address. Loop goes through net_ctx1 and dst
     doesn't match. But another if condition checks does this
     net_context mapped to net_app_ctx, yes it matches.
     So return net_ctx1, which is wrong.

So first go through all elements in array of net_contexts for
matching dst address, if it fails to find then go for matching
net_app_ctx.

Paul Sokolovsky 996c6dd603 net: if: Handle new address type of NET_ADDR_OVERRIDABLE
The meaning of this address type is the same as NET_ADDR_MANUAL,
but with a provision that DHCP can override such an address.
It's intended for the usecase when there's a default static
configuration for when DHCP is not available, but DHCP should
override it.

Before going to add another address type, there was an attempt
to repurpose TENTATIVE address state, but it doesn't work as
expected, as indeed, all existing address types/states already
have clearly semantics, and it makes sense to just another
address type to avoid confusion and unexpected behavior.

When testing TLS connections on production web server, it was noticed
that the TLS mainloop was getting "hung" after a connection was made

being notified that the connection was closed and was stuck waiting
for more data.

The next time that connection was used, TLS would fail to start.

is notified of the connection closure.  This allows the connection to

Sebastian Bøe 12f8f76165 Introduce cmake-based rewrite of KBuild
Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.

Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.

This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.

For users that just want to continue their work with minimal
disruption the following should suffice:

Install CMake 3.8.2+

Port any out-of-tree Makefiles to CMake.

Learn the absolute minimum about the new command line interface:

$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..

$ cd build
$ make
