0a9ed4e12b net: http: Deprecate old HTTP library
The old HTTP server and client library code is deprecated. The
new HTTP library will be based on net-app API code which requires
changes to function names and parameters that are not compatible
with old library.

018198cedc net: buf: Add slist helpers
Now that net_buf has "native" support for sys_slist_t in the form of
the sys_snode_t member, there's a danger people will forget to clear
out buf->frags when getting buffers from a list directly with
sys_slist_get(). This is analogous to the reason why we have
net_buf_get/put APIs instead of using k_fifo_get/put.

818a96d3af userspace: assign thread IDs at build time
Kernel object metadata had an extra data field added recently to
store bounds for stack objects. Use this data field to assign
IDs to thread objects at build time. This has numerous advantages:

* Threads can be granted permissions on kernel objects before the
  thread is initialized. Previously, it was necessary to call
  k_thread_create() with a K_FOREVER delay, assign permissions, then
  start the thread. Permissions are still completely cleared when
  a thread exits.

* No need for runtime logic to manage thread IDs

* Build error if CONFIG_MAX_THREAD_BYTES is set too low

b007b64d30 kernel: Add option to ensure writable pages are not executable
This adds CONFIG_EXECUTE_XOR_WRITE, which is enabled by default on
systems that support controlling whether a page can contain executable
code.  This is also known as W^X[1].

Trying to add a memory domain with a page that is both executable and
writable, either for supervisor mode threads, or for user mode threads,
will result in a kernel panic.

There are few cases where a writable page should also be executable
(JIT compilers, which are most likely out of scope for Zephyr), so an
option is provided to disable the check.

Since the memory domain APIs are executed in supervisor mode, a
determined person could bypass these checks with ease.  This is seen
more as a way to avoid people shooting themselves in the foot.

f801c1ca8e net: buf: Add net_buf_id() API
Add a net_buf_id() API which translates a buffer into a zero-based
index, based on its placement in the buffer pool. This can be useful
if you want to associate an external array of meta-data contexts with
the buffers of a pool.

The added value of this API is slightly limited at the moment, since
the net_buf API allows custom user-data sizes for each pool (i.e. the
user data can be used instead of a separately allocated meta-data
array). However, there's some refactoring coming soon which will unify
all net_buf structs to have the same fixed (and typically small)
amount of user data. In such cases it may be desirable to have
external user data in order not to inflate all buffers in the system
because of a single pool needing the extra memory.

Previously, post_write and execute callbacks returned 1 when handled
and 0 for error condition.  However, this wasn't detailed enough and
the engine can't propagate any sort of error back to users -- so it

The page_layout API returns pointers to kernel memory and is not
exposed to user mode. This is fine for flash_get_page_count()

generated, the definition of struct flash_pages_info needed to be
moved outside of the #ifdef.

427397216f kernel: Preprocessor Undef warning fix in kernel.h
_POLL_NUM_TYPES & _POLL_NUM_STATES are values of an enum, which the
preprocessor does not know about.
But the first of the removed lines needs to be evaluated by the
preprocessor using them.

The result is that the preprocessor will treat _POLL_NUM_TYPES
and _POLL_NUM_STATES as 0 in that expression, which would not seem the
intended behavior. It will also produce 2 warnings about this in each
file which includes kernel.h (lots)

=> lines 3779-3781 are be removed.

formatter reader / writers to use net_pkt APIs for parsing
across multiple net buffers. The current implementation assumes
all of the data will land in 1 buffer.

09b967366f net: pkt: Use standard macros to define system pkt slabs/pools
Previously net_pkt.h, defined macros NET_PKT_TX_SLAB_DEFINE,
NET_PKT_DATA_POOL_DEFINE, but advertised them as intended for
"user specified data". However, net_pkt.c effectively used the
same parameters for slabs/pools, but this wasn't obvious due
to extra config param redirection. So, make following changes:

1. Rename NET_PKT_TX_SLAB_DEFINE() to NET_PKT_SLAB_DEFINE()
as nothing in its definition is TX-specific.
2. Remove extra indirection for config params, and use
NET_PKT_SLAB_DEFINE and NET_PKT_DATA_POOL_DEFINE to define
system pools.
3. Update docstrings for NET_PKT_SLAB_DEFINE and
NET_PKT_DATA_POOL_DEFINE.

Overall, this change removes vail of magic in the definition of
system pkt slabs/pools, making obvious the fact that any packet
slabs/pools - whether default system or additional, custom - are
defined in exactly the same manner (and thus work in the same manner
too).
