Paul Sokolovsky 8f690e291b lib: fdtable: FD method tables should be const.
FD method tables contain function pointers, and thus should be
const and reside in ROM. This patch fixes all cases of FD vtable
definitions: for POSIX FS API and for sockets.

Paul Sokolovsky f750ce56ce net: lib: sockets: Switch to use fdtable
Previously the "socket file descriptors" were just net_context
pointers cast to int. For full POSIX compatibility and support
of generic operations line read/write/close/fcntl/ioctl, the
real file descriptors should be supported, as implemented by
fdtable mini-subsys.

Socket implementation already has userspace vs flatspace dichotomy,
and adding to that ptr-fds vs real-fds dichotomy (4 possible cases)
is just too cumbersome. So, switch sockets to real fd's regardless
if full POSIX subsystem is enabled or not.

Ravi kumar Veeramally c8954d3544 net: coap: CoAP library support over sockets
CoAP library is migrated to support over socket based
applications or other higher layer protocols. Most of the
API's and functionality is kept as it is except few changes.

net_pkt/net_buf is removed from CoAP library. Now it expects
a pre-allocated flat buffer and length. If there is not enough
space to append any data, library simply returns an error.
It's user's responsibility to allocate and free memory.

One change in functionality is, earlier coap_pending_clear()
used to clear the memory, but now it's user's responsibility
to free the memory.

Current TLS socket implementation assumed that PSK ID stored in

approach is less confusing, when a user is not operating on C strings

Andy Ross b8ffd9acd6 sys_clock: Make clock_always_on true by default
This flag is an indication to the timer driver that the OS doesn't
care about rollover conditions of the tick count while idling, so the
system doesn't need to wake up once per counter flip[1].  Obviously in
that circumstance values returned from k_uptime_get_32() are going to
be wrong, so the implementation had an assert to check for misuse.

But no one understood that from the docs, so the only place these APIs
were used in practice were as "guards" around code that needed to call
k_uptime_get_32(), even though that's 100% wrong per docs!

Clarify the docs.  Remove the incorrect guards.  Change the flag to
initialize to true so that uptime isn't broken-by-default in tickless
mode.  Also move the implemenations of the functions out of the
header, as there's no good reason for these to need to be inlined.

[1] Which can be significant.  A 100MHz ARM using the 24 bit SysTick
    counter rolls over at about 6 Hz, and if it had to come out of
    idle at that rate it would be a significant power issue that would
    swamp the gains from tickless.  Obviously systems with slow
    counters like nRF or 64 bit ones like RISC-V or x86's TSC aren't
    as affected.

Taehwa Kang 2bdc5923ad net: coap: Fix Coap coap_option_value_to_int and coap_append_option_int
In coap_option_value_to_int function, when coap option length is 4,
option->value[3] should be shifted by 0 rather than option->value[2].
This doesn't affect the behavior of function but needs to be fixed.

In coap_append_option_int function, when the value is between 0xffff
and 0xffffff(when option length is 3), bit shift operation is wrong.
For example, if the value is 0xABCDEF, by sys_put_be16(val, data)
data[0]=0xCD, data[1]=0xEF, by val >> 16, data[2]=0xAB. So the result
becomes 0xCDEFAB not 0xABCDEF. So, to sys_put_be16 function hand
&data[1] over instead of handing data over and val >> 16 needs to be
set to data[0], not data[2].

This patch enables BSD socket offload to a dedicated

This provides a simpler, more direct mechanism than going
through NET_OFFLOAD (zsock -> net_context -> socket conversions)
for those devices which provide complete TCP/IP offload at the
BSD socket level, and whose use cases do not require
IP routing between multiple network interfaces.

To use, configure CONFIG_NET_SOCKETS_OFFLOAD=y, and register
