e98f5d37f5 net: sockets: Store socket private data into its own variable
Do not try to re-use net_context.user_data field as in many places
(like in accept) it is expected to contain pointer to net_context.
Storing the socket flags will corrupt the value. To simplify and
make things less error prone, use socket specific field in net_context
to store the socket flags.

063fefd15d net: openthread: Use Zephyr's mbedTLS instead of compiling own
So far OpenThread compiled it's own, internal copy of mbedTLS library.
This commit changes this behavior by using Zephyr's mbedTLS instance
appropriately configured for OpenThread needs.

Generic mbedTLS config file was used in this case, so that application
can still configure remaining parts of mbedTLS for it's own needs.

207943c2a7 net: pkt: Clone cursor position in net_pkt_clone()
We need to make sure that net_pkt_clone() sets cursor correctly.
This cursor position is needed so that we can skip IP header

6564974bae userspace: Support for split 64 bit arguments
System call arguments, at the arch layer, are single words.  So
passing wider values requires splitting them into two registers at
call time.  This gets even more complicated for values (e.g
k_timeout_t) that may have different sizes depending on configuration.
This patch adds a feature to gen_syscalls.py to detect functions with
wide arguments and automatically generates code to split/unsplit them.

Unfortunately the current scheme of Z_SYSCALL_DECLARE_* macros won't
work with functions like this, because for N arguments (our current
maximum N is 10) there are 2^N possible configurations of argument
widths.  So this generates the complete functions for each handler and
wrapper, effectively doing in python what was originally done in the
preprocessor.

Another complexity is that traditional the z_hdlr_*() function for a
system call has taken the raw list of word arguments, which does not
work when some of those arguments must be 64 bit types.  So instead of
using a single Z_SYSCALL_HANDLER macro, this splits the job of
z_hdlr_*() into two steps: An automatically-generated unmarshalling
function, z_mrsh_*(), which then calls a user-supplied verification
function z_vrfy_*().  The verification function is typesafe, and is a
simple C function with exactly the same argument and return signature
as the syscall impl function.  It is also not responsible for
validating the pointers to the extra parameter array or a wide return
value, that code gets automatically generated.

This commit includes new vrfy/msrh handling for all syscalls invoked
during CI runs.  Future commits will port the less testable code.

1a6f4a6368 net: tcp: Accept connections only in LISTENING state
Issue noticed with following scenario.

 1) TCP server is listening for connections but will handle
    only one connection at a time (e.g. echo-server sample)
 2) Client A connects, and the connection is accepted.
 3) Client B connects, instead of denying a connection,
    it is "auto" accepted (this is the actual bug) even
    if the application has not called accept().
 4) After the connection A is closed, the connection B
    gets accepted by application but now the closed
    connection A will cause confusion in the net-stack
 5) This confusion can cause memory leak or double free
    in the TCP core.

It is not easy to trigger this issue because it depends
on timing of the connections A & B.

a4f4f6d6f3 net: net_if: avoid deref of NULL L2
When using offloaded network, an L2 is never assigned to the net_if.
Only certain portions of the net_if code are referenced such as:
net_if_up()
net_if_down()

And these functions make use of several L2 references:
get_flags()
enable()

Let's add checks to make sure we don't deref a NULL when using these
functions.

9103403308 net: lwm2m: support NET_SOCKETS_OFFLOAD in peer parsing
The LwM2M implementation for DNS resolving has checks which
configure hints based on whether IPv4 or IPv6 are enabled.
Neither of them need enabled if using NET_SOCKETS_OFFLOAD,
which then causes an error to be returned to due to
"hints.ai_family" not being set.

Also the offload API need to know when to free the allocated
"struct addrinfo" instead of calling free() generically,
thus let's use the freeaddrinfo() API for sockets which will
call into the offload API if needed.

7841ebf312 net: lwm2m: firmware_pull: fix multiple last_block notifications
When the firmware_pull mechansim sends the callback to notify the
sample of a new firmware block, the user supplied buffer can be
smaller than the CoAP BLOCK_SIZE setting.  To handle this case,
we loop through the payload and fill the user supplied buffer with
smaller chunks.

Unfortunately, the last_block calculation is done outside this loop
which causes several callbacks (while in this loop) to have
last_block true.   Let's fix this by adding a small check to make
sure we're at the end of the current payload block before notifying
the user of a last_block.

Formatting a float32/64 value for plain text is broken.
Example for 32bit: val1=0 and val2=500000 is equivalent to 0.5

Current formatter was using %d.%d (%lld.%lld for 64bit) so
exported value was 0.500000 (or 0.5)

To fix this, for val2 use a zero-padded formatter for the maximum
length of each bit length (6 for 32bit and 9 for 64bit), and then
remove the zero characters at the end of the string.

Notes re: handling of val1/val2 signs:
- eliminate potential negative sign when converting val2 to avoid:
  a value like: 0.-5
- use negative val2 when val1 is 0 to fix small negative handling
  such as -0.5
