When new route is allocated, a corresponding NBR entry (containing

management module (nbr.c) was dereferenced. This lead to a resource
leak, effecitevly leaking one `net_route_nexthop_pool` entry for each

Transition the `user_data` field in `struct net_buf` to be a flexible
array member instead of a hardcoded array. Compile-time asserts are
introduced at the location of the intermediate struct usage to ensure
that the assumptions utilised in runtime code hold true.
The primary assumptions are that the two `user_data` fields exist at the
same memory offset, and that the instantiated struct size can be
determined from the generic struct size and the length of the user data.
`net_buf_id` and `pool_get_uninit` must now use manual address
calculations as the `__bufs` type is no longer the actual size of the
instantiated variable.

Store the `user_data` array size on both the pool and net_buf structs.
This will enable length validation once `user_data` fields are not
globally the same size. The new variables fit inside existing padding,
and therefore do not increase the size of either structure.

There was a problem with source address selection for ARP
retransmissions, when an ARP entry was already pending. In such case,
the `entry` value passed to `arp_prepare()` is NULL, which in result
caused the `current_ip` variable being used as the source value. The
problem with this approach is, that the `current_ip` is only set in
IPv4 autoconf, the Ethernet L2 does not set this variable. In result,
every retransmission of an ARP packet was sent with unspecified source
address, preventing the response from being handled.
Fix this by partially restoring the behaviour of the ARP source address
assignment from before IPv4 autoconf was introduced. If the ARP is sent
by the IPv4 autoconf, use the `current_ip` value provided. If entry is
not set, use the source IPv4 address set in the actual data packet.
Otherwise, search for a source address on the interface corresponding to
the `entry`.

Closing a connection, thus calling net_context_put() will not close a
TCP connection properly, and will leak tcp connection memory.
This is because: net_context_put calls net_context_unref which calls
net_tcp_unref which leads to unref tcp connection and thus sets
ctx->tcp to NULL. Back to net_context_put, that one finally calls
net_tcp_put: but that bails out directly since ctx->tcp is NULL.

ipv6_prefix_find() wrongly tests if the unicast address is in use
instead of the prefix. This has two implications:
- The function can return an expired prefix to net_if_ipv6_prefix_add(),
which will do nothing more to enable it (since it assumes that it is
already enabled). As a result, the prefix will not be used by the
rest of the stack due to prefix->is_used being false.
- ipv6_prefix_find() loops using a bound of NET_IF_MAX_IPV6_PREFIX, but
the size of the unicast[] array is defined by NET_IF_MAX_IPV6_ADDR.

The irq_lock() usage here is incompatible with SMP systems, and one's
first reaction might be to convert it to a spinlock.
But are those irq_lock() instances really necessary?
Commit 6161ea2542 ("net: socket: socketpair: mitigate possible race
condition") doesn't say much:
> There was a possible race condition between sock_is_nonblock()
> and k_sem_take() in spair_read() and spair_write() that was
> mitigated.
A possible race without the irq_lock would be:
thread A thread B
| |
+ spair_write(): |
+ is_nonblock = sock_is_nonblock(spair); [false]
* [preemption here] |
| + spair_ioctl():
| + res = k_sem_take(&spair->sem, K_FOREVER);
| + [...]
| + spair->flags |= SPAIR_FLAG_NONBLOCK;
| * [preemption here]
+ res = k_sem_take(&spair->sem, K_NO_WAIT); [-1]
+ if (res < 0) { |
+ if (is_nonblock) { [skipped] }
* res = k_sem_take(&spair->sem, K_FOREVER); [blocks here]
| + [...]
But the version with irq_lock() isn't much better:
thread A thread B
| |
| + spair_ioctl():
| + res = k_sem_take(&spair->sem, K_FOREVER);
| + [...]
| * [preemption here]
+ spair_write(): |
+ irq_lock(); |
+ is_nonblock = sock_is_nonblock(spair); [false]
+ res = k_sem_take(&spair->sem, K_NO_WAIT); [-1]
+ irq_unlock(); |
* [preemption here] |
| + spair->flags |= SPAIR_FLAG_NONBLOCK;
| + [...]
| + k_sem_give(&spair->sem);
| + spair_read():
| + res = k_sem_take(&spair->sem, K_NO_WAIT);
| * [preemption here]
+ if (res < 0) { |
+ if (is_nonblock) { [skipped] }
* res = k_sem_take(&spair->sem, K_FOREVER); [blocks here]
In both cases the last k_sem_take(K_FOREVER) will block despite
SPAIR_FLAG_NONBLOCK being set at that moment. Other race scenarios
exist too, and on SMP they are even more likely.
The only guarantee provided by the irq_lock() is to make sure that
whenever the semaphore is acquired then the is_nonblock value is always
current. A better way to achieve that and be SMP compatible is to simply
move the initial sock_is_nonblock() *after* the k_sem_take() and remove
those irq_locks().

The purpose of shift_packets() is to make room to insert one fragment in
the list. This is not what it does currently, potentially leading to
-ENOMEM even if there is enough free room.
To see the current behaviour, let's assume that we receive 3 fragments
in reverse order:
- Frag3(offset = 0x40, M=0)
- Frag2(offset = 0x20, M=1)
- Frag1(offset = 0x00, M=1)
After receiving Frag3 and Frag2, pkt[] will look like:
.-------.-------.-------.
| Frag2 | Frag3 | NULL |
| 0x20 | 0x40 | |
'-------'-------'-------'
pkt[0] pkt[1] pkt[2]
When receiving Frag1, shift_packets(pos = 0) is called to make some room
at position 0. It will iterate up to i = 2 where there is a free
element. The current algorithm will try to shift pkt[0] to pkt[2], which
is indeed impossible but also unnecessary. It is only required to shift
pkt[0] and pkt[1] by one element in order to free pkt[0] to insert
Frag1.
Update the algorithm in order to shift the memory only by one element.
As a result, the ENOMEM test is only simpler: as long as we encounter
one free element, we are guaranteed that we can shift by one element.
Also assign a NULL value to the newly freed element since memmove() only
copy bytes.

Currently net_ipv6_handle_fragment_hdr() performs 2 distinct tests: it
checks the M-bit of the most recent fragment to decide if we can proceed
with the reassembly. Then it performs some sanity checks which can lead
to dropping the whole packet if not successful.
The test on the M-bit assumes that fragments arrive in order. But this
will fail if packets arrive out-of-order, since the last fragment can
arrive before some other fragments. In that case, we proceed with the
reassembly but it will fail because not all the fragments have been
received.
We need a more complete check before proceeding with the reassembly:
- We received the first fragment (offset = 0)
- All intermediate fragments are contiguous
- The More bit of the last fragment is 0
Since these conditions can also detect a malformed fragmented packet, we
can replace the existing sanity check that is performed before
reassembly. As a bonus, we can now detect and rejected overlapping
fragments, since this can have some security issues (see RFC 5722).

Currently prev_hdr_offset always equals 6, which is the offset of
the nexthdr field in the IPv6 header. This value is used to overwrite it
when removing an IPv6 Fragment header, so it will work as long as there
is no other Extension header between the IPv6 header and the Fragment
header.
However this does not work in the other cases: the nexthdr field of the
IPv6 header will be overwritten instead of the nexthdr field of the last
Extension header before the Fragment, leading to unwanted results.
Update prev_hdr_offset so that it always point to the nexthdr field of
the previous header, either the IPv6 header or an Extension header.
Signed-off-by: Florian Vaussard <florian.vaussard@gmail.com>
The current validation code waits to process the header before rejecting
it, while some checks can be already enforced when reading the nexthdr
field of the previous header.
The main problem is a wrong pointer field in the resulting ICMPv6 error
message: the pointer should have the offset of the invalid nexthdr
field, while currently it will the offset the invalid header.
To solve that problem, reorganize the loop in two parts: the first
switch validates nexthdr, while the second switch processes the current
header. This allows to reject invalid nexthdr earlier.

When an unknown option is encountered, an ICMPv6 error message must be
sent in some cases. The message contains a pointer field, which must be
the offset to the unknown option. Currently the offset is computed from
the beginning of the option list, while it should be computed with
respect to the beginning of the IPv6 header.
Record the offset when reading the option type and pass it later to
ipv6_drop_on_unknown_option() to correctly set the pointer field. Also
rename the argument in ipv6_drop_on_unknown_option() to make the
purpose more clear.

The Counter resource in the IPSO Push Button object was incremented

HTTP_DATA_FINAL was incorrectly notified in case Content Length field
was present in the HTTP respone - in such case it was set for every
response fragment, not only the last one.
Fix this by relying on `message_complete` flag instead of
`http_should_keep_alive()` function to determine whether to notify
HTTP_DATA_FINAL or not. As the HTTP parser calls the
`on_message_complete()` callback in either case (response is chunked or
not), this seems to be a more reasonable apporach to determine whether
the fragment is final or not.
Additinally, instead of calling response callback for
`on_body`/`on_message_complete` separately, call it directly from
`http_wait_data()` function, after the parsing round. This fixes the
case when headers were not reported correctly when the provided buffer
was smaller than the total headers length, resulting in corrupted data
being reported to the user.

According to the specificaion, resources are not predefined to use 32 or
64 bit floating point numbers, but should rather accept any of them (as
indicated by the size of the TLV in the message). This lead to issues
for instance with Eclipse Leshan LWM2M server, where Leshan sent 64-bit
value, while Zephyr expected 32-bit, making it impossible to write
the resource.
Therefore, unify the float usage to 32-bit float representation and fix

The `poll()` function did not report POLLHUP if the peer ended the DTLS
session, making it impossible to detect such event on the application
side.
On the other hand, TLS erroneusely reported POLLHUP along with each
POLLIN event, as the 0 returned by the `recv()` socket call was
wrongly interpreted (it was expected to get 0 in return as 0 bytes were
requested).
Fix this by introducing a helper function to process the mbedtls context

Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>
As the resource values represented by the unsigned integers were casted
to integers of a corresponding size in the read handler, they were not
ecoded properly if the unsigned value was larger than the maximum
integer value of the corresponding size (i.e. they were encoded as
negative values).
Fix this by casting the unsinged value to a wider integer type, to
prevent incorrect interpratetion of the data provided. The TLV encoding
functions take care of the optimization (i. e. encoding integers on the
minimum number of bytes needed), so it should prevent bandwith waste if
the unsigned value would actually fit into the integer of the
corresponding size.
Similar case is for the write hander, where unsigned integers encoded at
8 bytes were not processed correctly. Fix this by using wider decoder as
well.

This restructures the lwm2m_engine to use a non-blocking socket access
instead of the previously used blocking style, and eliminates any
socket-access from outside of the main work loop.
The main motivation behind this is an issue within nordics
nrf_modem_lib/modem-fw on nrf9160, that leads to socket send() calls to
block indefinitely when the shared memory used for
rpc-communication with the modem is already exhausted because of
incoming data.
This lead to the lwm2m_engine locking up on send calls when there is
also a large amount of incoming data.
This works around this issue, by only issuing send calls when poll
reports the socket to be ready for sending, and (more importantly) by
always receiving all buffered incoming data before sending anything.
There might still be a (perhaps academic) possibility where this
situation might be triggered, when the scheduler interrupts the lwm2m
thread in-between receiving and sending, but for now we have not yet
observed this.
Besides working around the aforementioned issue, this also simplifies
the way resends are handled as they are no longer send from the main
system-workqueue, and limits all interaction with the sockets to a
single thread.

Fix a regression when application is waiting data but does
not notice that because socket layer is not woken up.
This could happen because application was waiting condition
variable but the signal to wake the condvar came before the
wait started. Normally if there is constant flow of incoming
data to the socket, the signal would be given later. But if
the peer is waiting that Zephyr replies, there might be a
timeout at peer.
The solution is to add locking in socket receive callback so
that we only signal the condition variable after we have made
sure that the condition variable is actually waiting the data.

the semaphore release, the thread that is waiting on connect()

After the recent OpenThread upmerge, OpenThread changed its behaviour in
terms of CLI handling during commissioning procedure. OpenThread will
now call the registered CLI callback when it recieves the Discovery
message.
This resulted in a crash if no CLI command was executed by the user
before, because the `shell_p` pointer was only set in the command
handler. As it was not set to the actual shell backend instance, it
caused a crash (or assert if enabled) in the `shell_vfprintf()`
function.
Fix this by verifying the `shell_p` pointer in the

OpenThread modified its NCP API, so we need to align with these changes
in Zephyr.
One of the major changes was removal of UART from the platform APIs.
`openthread/platform/uart.h` header file was moved to
`examples/platforms/util/uart.h` so we need to use the new location in
Zephyr. This means that OpenThread no longer impose the UART API but for
the simplicity of the upmerge I've kept the UART APIs as they are for
now.
The NCP initialization function have now to register a send handler,
and the appropriate transport driver have to call NCP callbacks when
transmission/reception is done. For now, re-use the existing code of
the UART driver, just as the upstream NCP application does.

Zephyr socket subsystem has come a long way since initial experimental
alternative to internal Zephyr networking API. Its configuration also
mirrors the usual conservative approach, where a user needs to
explicitly enable options to get "more" features. And as an
experimental API, socket subsystem was initially developed as
namespaced API, where all functions/structures are prefixed with
"zsock_", and to get standard names, CONFIG_NET_SOCKETS_POSIX_NAMES
needs to be set (or alternatively, CONFIG_POSIX_API needs to be, which
enabled full POSIX subsys overall).
However, a few years later, sockets are the standard networking API,
and in majority of cases its used under the standard POSIX names.
Necessity to explicitly set an option to achieve this effects, and
confusion which results from it - are just unneeded chores for users.
So, switch CONFIG_NET_SOCKETS_POSIX_NAMES to be on by default (unless
CONFIG_POSIX_API is already defined). It still can be explicitly
disabled if needed (but usecases for that would be peculiar and rare).

The specification states that the server can cancel observations "at any
moment, by sendinga GET request with Observe option=1, the LwM2M Server
cancancel an “Observe”operation on a specified Resource, or specified
Object Instance(s)."
It does not mention any token matching requirement, but RFC 7641 does.
The correct interpretation is not obvious. The EMQx LwM2M implementation
uses a new token for instance, which does not work with Zephyrs token
matching cancel-observe.
This commit introduces cancel-observe via path matching as a Kconfig
option. This could hypothetically introduce problems when we are
connected to multiple peers simultaneously, but since that is not likely
to be supported for a long time (if ever), this change should be fairly
uncontroversial since path matching is only used as a fallback.

Current implementation of poll prepare/update could end up busy looping
if `poll()` function was called before/during DTLS client handshake
(i. e. `poll()` called before an initial `send()`).
Fix this, by monitoring the handshake semaphore, already available in
the tls_context structure for DTLS client instead of underlying socket.
After the handshake is complete, switch to monitoring the underlying
socket instead.
For DTLS server this is not needed, since the handshake is initiated in
the `recv()` function, therefore any incoming data should trigger the
handshake.

Currently there is no way to distinguish between a caller

Add `K_SEM_MAX_LIMIT`, currently defined to `UINT_MAX`, and akin

In addition, the `k_sem_*` APIs were type-confused, where
the internal data structure was `uint32_t`, but the APIs took
and returned `unsigned int`. This changes the underlying data
structure to also use `unsigned int`, as changing the APIs
would be a (potentially) breaking change.
These changes are backwards-compatible, but it is strongly suggested
to take a quick scan for `k_sem_init` and `K_SEM_DEFINE` calls with
`UINT_MAX` (or `UINT32_MAX`) and replace them with `K_SEM_MAX_LIMIT`

The tcp2 infrastructure is using the legacy delayed work API, and
relies heavily on the transient state indicated by an estimate of
delayed time remaining to determine whether a delayed work item is
still active. While the wrappers for this work in most cases, one use
is unsanctioned: directly accessing the fields of k_delayed_work
structure to satisfy the calling parameters of the handler when
invoked directly.
The chosen solution for this specific need in the new API is to use a
schedule (rather than reschedule) operation, which leaves any previous
timer unchanged but allows immediate submission if the work is idle.
This changes behavior in that the resend is delegated to the work
queue, rather than done immediately. The former behavior can be
supported by further refactoring that turns the work handler into a
wrapper around a function that takes a connection reference, and
invoking that here, while the handler invokes it after reconstructing
the connection from the contained work item.
For now put in a hack that also uses the non-public fields of the
delayed work structure to implement the required behavior. The
complete fix if this solution is used requires replacing all use of
k_delayed_work in this module with k_work_delayable, leveraging the
new functionality of the API to avoid having to guess about the true
state of a work item based on its transient timer or flag states.

This commit also replaces the usage of the size field in places where

Bootstrap discovery was not implemented properly in the LwM2M engine.

Given that Bootstrap Discovery procedure differs a lot from the regular

calculation.
Note a case where the racy idiom for retaining an existing timeout is

The existing implementation is inconsistent in that checking for
expired routers when a timeout is processed detects end-of-life
correctly (when the remaining duration exceeds the signed maximum),
but the calculation of time remaining before expiration uses only
unsigned calculation. So when the set of routers is changed the newly
calculated timeout will not recognize routers that have expired, and
so those routers expired late. In the worst case if the only
remaining router had expired the timer may be set for almost two
months in the future.
Refactor to calculate remaining time in one place and as a signed
value. Change a function name to more clearly reflect what it does.
Avoid unnecessary race conditions in k_work API.
Signed-off-by: Peter Bigot <peter.bigot@nordicsemi.no>
The net_timeout structure is documented to exist because of behavior
that is no longer true, i.e. that `k_delayed_work_submit()` supports
only delays up to INT32_MAX milliseconds. Nonetheless, use of 32-bit
timestamps within the work handlers mean the restriction is still
present.
This infrastructure is currently used for two timers with long
durations:
* address for IPv6 addresses
* prefix for IPv6 prefixes
The handling of rollover was subtly different between these: address
wraps reset the start time while prefix wraps did not.
The calculation of remaining time in ipv6_nbr was incorrect when the
original requested time in seconds was a multiple of
NET_TIMEOUT_MAX_VALUE: the remainder value would be zero while the
wrap counter was positive, causing the calculation to indicate no time
remained.
The maximum value was set to allow a 100 ms latency between elapse of
the deadline and assessment of a given timer, but detection of
rollover assumed that the captured time in the work handler was
precisely the expected deadline, which is unlikely to be true. Use of
the shared system work queue also risks observed latency exceeding 100
ms. These calculations could produce delays to next event that
exceeded the maximum delay, which introduced special cases.
Refactor so all operations that use this structure are encapsulated
into API that is documented and has a full-coverage unit test. Switch
to the standard mechanism of detecting completed deadlines by
calculating the signed difference between the deadline and the current
time, which eliminates some special cases.
Uniformly rely on the scanning the set of timers to determine the next
deadline, rather than assuming that the most recent update is always
next.

the end of the buffer.
The semantics of `net_buf_remove_mem` have been chosen to match those of
`net_buf_pull_mem`, i.e. the return value is a pointer to the memory

The opposite of this function, `net_buf_remove`, would need to return
the old end of the data buffer to be useful. However this value is
always an invalid target for reading or writing data to (It points to
the middle of unused data).The existance of the function would be
misleading, therefore it is not implemented.

If there are multiple interfaces a change to the timeout for one
cannot determine the correct delay until the next timeout event. That

When a renewal occurs the client enters RENEWING, sends a request,
then sets a short timeout (about 4 s) for the response. In the common
case the response will arrive immediately, which will trigger an
attempt to reset the timer with T1 which is generally large.
However the check for updating the timer performs the update only if
the new deadline is closer than the currently set one. Thus the timer
fires at the time the RENEWING request would have been retransmitted,
and only then updates to the correct deadline (T1) for the current
machine state.
Remove the extra timeout by unconditionally setting the timeout to the
new value.
This works when there is one interface; it could be wrong if there
were multiple interfaces one of which had a closer deadline, but
multiple interfaces are mishandled anyway and will be fixed next.
Signed-off-by: Peter Bigot <peter.bigot@nordicsemi.no>
When there is only a single interface the timeout infrastructure can
correctly calculate time to next event, because timeouts only occur
when an event for that interface is due. This is not the case when
multiple interfaces are present: the timeout is scheduled for the next
event calculated over all interfaces.
When calculating the next event for an interface where the timeout is
not due the current code returns the original absolute delay
associated with its current state, without accounting for the time
that has passed since the start time.
For example if interface A's T1 is 3600 s and is due at 3610, but at
3605 a timeout for interface B occurs, the contribution of A to the
delay to the next scheduled event would be 3600 rather than 5,
preventing the renewal from occurring at the scheduled time.
Fix this by replacing the boolean timed-out state with the number of
seconds remaining until the interface event will occur, and
propagating that through the system so the correct delay over all
interfaces can be maintained.

If send_request() fails it would return UINT32_MAX as the next
timeout. Callers pass the returned value to update_timeout_work
without validating it. This has worked only because
update_timeout_work will not set a timeout if an existing timeout
would fire earlier, and the way the state is currently structured it
is likely there will be an existing timeout. However, if work thread
retransmission from REQUESTING failed the timer would not be
rescheduled, causing the state machine to stop.
A more clean solution, which matches the behavior of send_discover(),
is to return the timeout for the next transmission even in the case
when the send fails. The observed behavior is the same as if the
network, rather than the sender, failed to transport the request.

Currently, when socket errors occur during receive, the LwM2M engine
restarts the state machine and registers again to the server. While this
works in simple use case (only RD client socket open), it's not a valid
approach when more sockets are open (FW update socket).
Fix this by introducing socket fault callback, which is registered by
the LwM2M engine users. This way, a proper socket owner is notified on
error and can pertake appropriate action.
For RD socket errors the behaviour remains the same - the state machine

Call mbedtls_ssl_conf_max_frag_len() on created TLS context
configuration, so that Maximum Fragment Length (MFL) will be sent to
peer using RFC 6066 max_fragment_length extension. MFL value is

When a connection is being closed, it is possible that the application
will have a lock to net_context and TCP2 connection lock. If we then
receive a final TCP2 ACK and close the connection, the locking order
get switched and TCP2 will first try to get its own lock and then the
net_context lock. This will lead to deadlock as the locking ordering
is now mixed.
The solution is to unref the TCP connection after releasing the
connection lock. The TCP connection unref function will anyway get the
lock so no need to do double locking.

According to LwM2M specfication v1.0.2, par. 5.3.2, the LwM2M client
MUST send an “Update” operation to the LwM2M Server whenever the
lifetime parameter of the Server object changes the server). The same
applies for the object instances created/deleted. The changes in objects
seem to already be handled, but the lifetime was not.
Additionally, the "Update" message shall only contain these parameters
which changed since the last update (including objects). As it's
straightforward to determine if the liftime changed but it's not easy
to tell if there were updates in the object instances, add an
additional parameter to the engine_trigger_update() function, indicating
that new object information shall be sent in the "Update" message.
Eventually add a proper error checking in `sm_send_registration` as the
function is reworked anyway.

It shouldn't be optional to handle separate response, as it's a
mandatory requirement according to the RFC7252:
"The protocol leaves the decision whether to
piggyback a response or not (i.e., send a separate response) to

Therefore, remove the flag as separate responses are handled now
properly.

Separate response handling implemented in the engine was faulty. The
separate response was not acknowledged by the client, resulting in
spurious retransmissions from the server side.
Also, the pending CON message was retransmitted by the client even after
it was acknowledged by an empty ACK, but the respnse haven't arrived
yet. Fix this by adding a new `acknowledged` flag to the `lwm2m_message`
structure. Once acknowledged, the flag is set and the confirmable
message is no longer retransmitted. We keep the message on the pending
list in order to timeout properly in case separate response does not
arrive in time.
Finally, prevent the reply callback from being called twice in case
the response is transmitted separately from ACk. The callback should
only be called on the actual reply, not the empty ACK.

Prior to this commit, the LwM2M stack would TLV-encode integers
depending on their internal storage size. An integer with value 5 stored
in an int8_t would be encoded with length 1, but an integer stored in an
int32_t would be encoded as "00 00 00 05" with length 4.
This commit checks if the value is castable to a smaller int and encodes
it as such if so. This is cascading, so even a 64 bit integer with value
5 will be encoded with length 1.
Note that this does not seem to be required by the specification, but
this is how Anjay and the other LwM2M stack seem to do it.

Fix this, by replacing the current `data_len` field of the

* Removed faulty `get_length_left` function from the plain text

actual payload size.
* Introduce `struct lwm2m_opaque_context` as a part of block context,
which allows to keep track of opaque data download progress.
* Simplify `lwm2m_write_handler_opaque()` function. It will now only
make calls to `engine_get_opaque` - it's the decoder responsibility
to update the opaque context according to it's content format (for
instance TLV decoder should only update it with the actual opaque

MQTT client state is protected using mutex. That mutex however is
temporarily unlocked when calling event callbacks. This means that in
client_disconnect() transport can already be disconnected, but without
marking it as such in client->internal.state.
When mutex is unlocked in event_notify() function, then there are two
possible paths of failure:
1) First possibility is when RX and TX are called from two separate
threads, so that the other thread gets resumed and functions like
verify_tx_state() (e.g. in mqtt_publish()) allow to continue
communication over disconnected medium.
2) Another possibility is that user calls mqtt_abort() or
mqtt_disconnect() in event handler.
In both cases MQTT library tries to send or receive data, possibly
followed by second close() of underlying file descriptor.
Prevent using disconnected transport by clearing MQTT client state right
after calling mqtt_transport_disconnect(), without releasing mutex, even
for a while.

Bug description:
When in tcp_conn_unref(), in case one of the delayed works is already
submitted to sysworkq (after delay period), e.g. send_timer, the check
of k_delayed_work_remaining_get() prevents calling
k_delayed_work_cancel().
This leads to corrupting sysworkq when zeroing struct tcp* conn.
Note that the "next" pointer for the work queue is part of the struct
work (in _reserved field). Which is, in this case, a member of struct
tcp.
Scenario leading to the bug:
(1) net_tcp_connect() is called from a work in sysworkq
(2) net_tcp_connect() submits conn->send_timer to sysworkq
(3) while net_tcp_connect() is waiting on connect_sem, delay period
passes (z_timeout) and send_timer enters sysworkq work slist
(4) also, some other code (app) submits more works to queue, now pointed
by conn->send_timer in sysworkq work list
(5) connection fails (no answer to SYN), causing a call to
tcp_conn_unref()
(6) tcp_conn_unref() is calling tcp_send_queue_flush()
(7) checking k_delayed_work_remaining_get(&conn->send_timer) returns 0
due to delay period end, but send_timer is still in sysworkq work
slist (sysworkq thread still hasn't handled the work)
(8) BUG!: no call to k_delayed_work_cancel(&conn->send_timer)
(9) back in tcp_conn_unref(), a call to memset(conn, 0, sizeof(*conn))
zeroes conn->send_timer
(10) conn->send_timer is pointed to in sysworkq work slist, but is
zeroed, clearing pointer to following works submitted in stage (4)
(11) EFFECT! the works in stage (4) are never executed!!
NOTES:
* k_delayed_work_cancel(), handles both states:
(1) delayed work pends on timeout and
(2) work already in queue.
So there is no need to check k_delayed_work_remaining_get()
* This is also relevant for conn->send_data_timer
Solution:
removing checks of k_delayed_work_remaining_get(), always calling
k_delayed_work_cancel() for work in struct tcp, in unref, before memset

Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>
Given that the offloaded poll handling differs from the poll handling of
native sockets (entire poll function call is offloaded), some
adjustements were needed to make TLS socket work with offloaded poll
calls.
To achieve this, in case socket offloading is used, instead of jumping
directly to the offloaded poll call, a TLS wrapper for the offloaded
poll will be called. This wrapper will do additional checks at the
mbedtls level, to verify that the event is only notified to the caller
when the application data is available (i. e. not to report events
during handshake or when partial data is received, not ready to
decrypt).

PPP Phase Diagram [1] allows only one way phase change. In current
implementation there is an additional RUNNING phase, which is entered
just after NETWORK phase.
Prevent going back from RUNNING to NETWORK phase when Term-Req was
received, as this is meaningless for overall PPP operation and violates
PPP Phase Diagram property of having one way direction change.
This change also improves Adminitrative Close handling (calling
lcp_close()). This request results in moving into TERMINATE phase. Then
LCP is put down (by calling lcp_down()) and then ppp_link_down() is
called, which so far (before this patch) resulted in moving back to
NETWORK and then to DEAD. Right now (after this patch) we move directly
from TERMINATE to DEAD phase, which is exactly how [1] specifies it.

This patch implements optional authentication phase, which is done
between link establishment and network phases. It is part of LCP option
negotiation to decide whether authentication is needed and which
protocol will be used. For now we add only PAP support and try to
negotiate it when some other protocol (e.g. CHAP or EAP) is proposed
earlier. For simplicity reason we only add one way authentication
support, which means that we try to authenticate to the other peer, but
do not require authentication from it.
This is an important step to make PPP work with cellular network modems,
because most of them require to provide username and password within PPP
authentication phase. Those credentials are used by modem to login to
cellular network. In most cases however it is enough to provide dummy
values, because they are not verified. For this reason and simplicity of
this patch we hardcode PAP Peer-ID and Password now.

So far there was no generalized way how to handle negotiation of "my
options" (those sent with Conf-Req packet to peer). Peer response for
proposed options and their values were not tracked in any way, so
rejected (by peer) options were sent over and over again in subsequent
Conf-Req packets. In case of IPCP it means that all sent options such as
IP_ADDRESS, DNS1, DNS2 were mandatory for being supported by peer in
order to successfully finish negotiation. For example if 'pppd' was the
configured peer (e.g. when using with QEMU and net-tools scripts),
without ms-dns being configured (which is the default), then "my
options" negotiation failed.
Introduce generalized mechanism for negotiating "my options", so it is
easier to maintain current set of supported options and easily add new
options to the implementation in future. FSM instance inititialization
function can provide information about supported "my options".
Information is is passed as a table of 'struct ppp_my_option_info'
containing:
* option code (type),
* callback for adding option to Conf-Req packet,
* callback for received Conf-Ack with that option,
* callback for received Conf-Nak with that option.
Store also runtime information about each negotiated option. First of
all remember which options have been rejected, so they are not sent to
peer once again in the next Conf-Req packet. This will solve issue with
IPCP negotiation when peer doesn't support DNS1 or DNS2 options. Keep
also track about which options have been acked, so such information can
be verified before bringing FSM instance up.

When FW update in PUSH mode is used, the firmware is encapsulated in the
TLV as an opaque data, according to the LMWM2M satandard, and then
sliced into blocks and transferred block by block in several
transactions. Therefore, the TLV header is only present in the initial
message.
Current implementation did not handle this case well, reporting errors
on consecutive blocks, therefore making the FW update in PUSH mode
broken.
This commit fixes this issue with following changes:
* The TLV is only assumed to be present in the initial block, while
consecutive blocks will be processed directly into the appropriate
handler,
* 32-bit variables shall be used whenever dealing with the opaque data
length, since the firmware size can easily exceed the 16-bit range,
* Additional information, required for the FW block transfer to work
properly were added to the block context structure,
* The application shall only be notified of the actual data length, and
not the total block size (the total TLV size including header).

So far net config initialization code relied on number of services
needed by application. This was fine as long as all enabled
services (e.g. CONFIG_NET_IPV4=y, CONFIG_NET_IPV6=y) were selected by
project configuration as "needed" (e.g. CONFIG_NET_CONFIG_NEED_IPV4=y,
CONFIG_NET_CONFIG_NEED_IPV6=y). Problem appeared for example when both
IPv4 and IPv6 were enabled (CONFIG_NET_IPV4=y, CONFIG_NET_IPV6=y), but
only IPv6 was marked as "needed" (CONFIG_NET_CONFIG_NEED_IPV6=y). In
such situation number of required services was equal to 1. When IPv4
setup was completed, this resulted in returning from net_config_init()
function. Application code failed, because IPv6 was still not
functional.
Do not rely on number of services anymore, as it is error prone. Use
flags instead to mark which services are ready. Compare those flags with
the flags passed to net_config_init() (selected in project configuration
in most cases) to decide whether network configuration has completed
already or not.
Also introduce services_notify_ready() and services_are_ready() helper
functions to isolate implementation details from the logic.

The original sockets system calls used file descriptors which
were actually net_context pointers. For all socket system calls,
any calls from user mode would check if the caller had permission
to use the net context.
This was later changed to not stuff net_context pointers into file
descriptors, but all the permission checking was unintentionally
lost, allowing all threads on the system to
read/write all socket file descriptors in the system at will, with
no way to isolate applications running on the same microcontroller
from each other's network activity.
This patch restores the permission checks on network context objects
for socket system calls that originated from user mode.
The call to z_object_recycle() was never removed from
zsock_socket_internal(); this is again leveraged to grant the
caller who opened the socket permission on the net_context
associated with the returned file descriptor.
To ensure that all socket calls do this checking, all uses of
z_get_fd_obj_and_vtable() have been routed through get_sock_vtable().
Objects have initialization state set and thread permissions
reset to just the caller in common zsock_socket() code.

until there's an unsent data and the receiver's window isn't full.
tcp_send_queued_data() subscribes send_data_timer
that will handle retrasmissions with tcp_resend_data().
3. tcp_send_data() peeks a single chunk of data from the send_data
queue that will not exceed the maximum segment size
until the the receiver's window is full.
tcp_send_data() uses conn->seq and conn->unack_len as the sequence
number for the TCP packet.
conn->unacked_len is advanced on each send.
4. On data acknowledgment:
- acknowledged amount of data is removed from the beginning
of the send_data queue
- conn->seq is advanced by the acknowledged amount
- conn->unacked_len is decremented by the acknowledged amount
- send_data_timer is cancelled
- tcp_send_queued_data() is called to send queued but
prevoiusly unsent data
5. On timeout, tcp_resend_data() will reset conn->unack_len,
peek one packet from the beginning of the send_queue and resend,
terminating the connection on retries exceeded.
Meanwhile the outgoing data tcp_send_queued_data() is just
appended to the send_data but not sent.
In case of the acknowledgement, tcp_send_queued_data() will
start sending multiple packets until the receiver's window
is full.

So far socket errors reported by poll/recvfrom were ignored, which could
lead to an unexpected behavior when socket was left in an undefined

Fix this, by requesting a re-registration in the LWM2M state machine,
which will close the faulty socket and open a new one. Note, that simply
closing and re-opening a socket in the lwm2m engine would not work,
since this would silently invalidate any open observations on the
lwm2m server side (due to port number change). Triggering a fresh
registration will notify the server to update its observations.

The retaransmission logic was not correct in the lwm2m_engine, and could
lead to faulty behavior in case multiple messages were pending for
retransmission in the queue.
1. Since there is a singe delayed work item for entire retransmission
queue, `coap_pending_next_to_expire` should be called before
scheduling next timeout, to identify which message is going to expire
next (and when). Currently, the engine always set next timeout, based
on timeout from the message being currently re-transmitted.
2. In case the message was re-transmitted several times, and is removed
from the retansmission queue due to a timeout, next retransmission
should be scheduled, in case there are other messages on the queue.
3. Verify the timeout of the earliest message to expire in the
retransmission handler. In case messages from the beginning of the
queue were removed, we might need to schedule the retransmission
again, instead of sending message rightaway.
4. `lwm2m_send_message` is not handling retransmissions anyway, so
there's no need to check send attempts. Instead, verify
retransmission work item is already pending, and update its timeout
if needed.
Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>
So far, coap_pending structure kept track only of the timeout interval
between two consecutive retransmissions. Calculations inside
`coap_pending_next_to_expire` relied only on this value. This approach
gives incorrect results though, in case multiple messages are pending
for retransmission.
For instance, assuming initial retransmission timeout is set to 2
seconds. If some message had been retransmitted already, its timeout
would be increased to 4 seconds. Any new message added to the pending
list would have a retransmission timeout set to 2 seconds, and will be
returned as a first message to expire, no matter how long the initial
message was already on the list.
To resolve this, add a `t0` field to the coap_pending structure. This
field is initialized to the initial transmission time, and is increased
on each retransmission by the retransmission timeout.
`coap_pending_next_to_expire` uses this value to calculate absolute
time, when the next retransmission should take place, and based on this
information returns correctly first pending message to expire.

Bug fix and improved `payload` handling in `http_client_req`.
Changes to `http_client_req` behaviour:
If the user provides `payload_len` it is used to generate the
`Content-Length` header. This is done even if `payload_cb` is used to
provide the actual data. If no `payload_len` is specified then no
`Content-Length` is generated.
If `payload_cb` is provided it is called to send the payload data.
Otherwise `payload` is used as the payload buffer and sent. If
`payload_len` is not zero, it is used as the size of `payload`.
Otherwise `payload` is assumed to be a string and `strlen` is used to
determine its size. This is to maintain current behaviour and not break
existing samples.

This change is to allow access to the firmware block context in order to

downloaded. A simple implementation can check if the block context's
current downloaded blocks is equal to the expected block size in order
to determine if the flash context needs to be reset. This approach
seemed the simplest, and knowing the firmware block context can have
other purposes. This has been tested by accessing the block context
during the update in the block received callback and confirming that the
callback had information regarding the current downloaded bytes.

Even though radio driver can report in its capabilities that it does
support CSMA CA, there's no way in the driver to select how the frame
should be transmitted (with CSMA or without). As layers above radio
driver (Thread, Zigbee) can expect that both TX modes are available, we
need to extend the API to allow either of these modes.
This commits extends the API `tx` function with an extra parameter,
`ieee802154_tx_mode`, which informs the driver how the packet should be
transmitted. Currently, the following modes are specified:
* direct (regular tx, no cca, just how it worked so far),
* CCA before transmission,
* CSMA CA before transmission,
* delayed TX,
* delayed TX with CCA
Assume that radios that reported CSMA CA capability transmit in CSMA CA
mode by default, all others will support direct mode.

Add a k_timeout_t type, and use it everywhere that kernel API
functions were accepting a millisecond timeout argument. Instead of
forcing milliseconds everywhere (which are often not integrally
representable as system ticks), do the conversion to ticks at the
point where the timeout is created. This avoids an extra unit
conversion in some application code, and allows us to express the
timeout in units other than milliseconds to achieve greater precision.
The existing K_MSEC() et. al. macros now return initializers for a
k_timeout_t.
The K_NO_WAIT and K_FOREVER constants have now become k_timeout_t
values, which means they cannot be operated on as integers.
Applications which have their own APIs that need to inspect these
vs. user-provided timeouts can now use a K_TIMEOUT_EQ() predicate to
test for equality.
Timer drivers, which receive an integer tick count in ther
z_clock_set_timeout() functions, now use the integer-valued
K_TICKS_FOREVER constant instead of K_FOREVER.
For the initial release, to preserve source compatibility, a
CONFIG_LEGACY_TIMEOUT_API kconfig is provided. When true, the
k_timeout_t will remain a compatible 32 bit value that will work with
any legacy Zephyr application.
Some subsystems present timeout (or timeout-like) values to their own
users as APIs that would re-use the kernel's own constants and
conventions. These will require some minor design work to adapt to
the new scheme (in most cases just using k_timeout_t directly in their
own API), and they have not been changed in this patch, instead
selecting CONFIG_LEGACY_TIMEOUT_API via kconfig. These subsystems
include: CAN Bus, the Microbit display driver, I2S, LoRa modem
drivers, the UART Async API, Video hardware drivers, the console
subsystem, and the network buffer abstraction.
k_sleep() now takes a k_timeout_t argument, with a k_msleep() variant
provided that works identically to the original API.
Most of the changes here are just type/configuration management and
documentation, but there are logic changes in mempool, where a loop
that used a timeout numerically has been reworked using a new
z_timeout_end_calc() predicate. Also in queue.c, a (when POLL was
enabled) a similar loop was needlessly used to try to retry the
k_poll() call after a spurious failure. But k_poll() does not fail
spuriously, so the loop was removed.

Such state needs to be set _from_ the PM API functions and not the other
way round. So if a network device driver does not support such API, it
will not be able to set the core net_if on PM state, obviously.
Currently, these functions only set/unset NET_IF_SUSPENDED flag.
More logic will be added later, to decide whether the net_if can be
actually set to suspend mode or not and also to take care of all timers

We need to know whether the net_pkt was successfully placed
to transmit queue. It is possible in TX side, that the net_pkt
is already in TX queue when for example TCP packet is
re-transmitted, in which case the queue submit will fail.
This cannot happen in RX side as there are no timers involved.
It is required to check about such pending flag before trying to submit
it into the queue. Indeed, the work queue could be scheduled right after
such queuing, thus checking for the pending flag afterwards would
provide a false information.
It is unfortunate k_work_submit_to_queue() does not return anything as
it would simplify the code then.

There are scenarios where there is a NAT firewall in between MQTT
client and server. In such case, the NAT TCP timeout may be shorter
than MQTT keepalive timeout and TCP timeout. The the MQTT ping
request message is dropped by the NAT firewall, so that it cannot be
received by the server, resulting in void MQTT ping response message.
There is no TCP FIN or RST at all. The application looks hang-up
until TCP timeout happens on the client side, which may take too
long.
Therefore, the event MQTT_EVT_PINGRESP is added to inform the
application that the route between client and server is still valid.

I think people might be reading differences into 'if' and 'depends on'
that aren't there, like maybe 'if' being needed to "hide" a symbol,
while 'depends on' just adds a dependency.
There are no differences between 'if' and 'depends on'. 'if' is just a
shorthand for 'depends on'. They work the same when it comes to creating
implicit menus too.
The way symbols get "hidden" is through their dependencies not being
satisfied ('if'/'depends on' get copied up as a dependency on the
prompt).
Since 'if' and 'depends on' are the same, an 'if' with just a single
symbol in it can be replaced with a 'depends on'. IMO, it's best to
avoid 'if' there as a style choice too, because it confuses people into
thinking there's deep Kconfig magic going on that requires 'if'.
Going for 'depends on' can also remove some nested 'if's, which
generates nicer symbol information and docs, because nested 'if's really
are so simple/dumb that they just add the dependencies from both 'if's
to all symbols within.
Replace a bunch of single-symbol 'if's with 'depends on' to despam the
Kconfig files a bit and make it clearer how things work. Also do some
other minor related dependency refactoring.
The replacement isn't complete. Will fix up the rest later. Splitting it
a bit to make it more manageable.
(Everything above is true for choices, menus, and comments as well.)

detect after parsing, because 'if' turns into 'depends on'.

This commit refactors kernel and arch headers to establish a boundary
between private and public interface headers.
The refactoring strategy used in this commit is detailed in the issue
This commit introduces the following major changes:
1. Establish a clear boundary between private and public headers by
removing "kernel/include" and "arch/*/include" from the global
include paths. Ideally, only kernel/ and arch/*/ source files should
reference the headers in these directories. If these headers must be
used by a component, these include paths shall be manually added to
the CMakeLists.txt file of the component. This is intended to
discourage applications from including private kernel and arch
headers either knowingly and unknowingly.
- kernel/include/ (PRIVATE)
This directory contains the private headers that provide private
kernel definitions which should not be visible outside the kernel
and arch source code. All public kernel definitions must be added
to an appropriate header located under include/.
- arch/*/include/ (PRIVATE)
This directory contains the private headers that provide private
architecture-specific definitions which should not be visible
outside the arch and kernel source code. All public architecture-
specific definitions must be added to an appropriate header located
under include/arch/*/.
- include/ AND include/sys/ (PUBLIC)
This directory contains the public headers that provide public
kernel definitions which can be referenced by both kernel and
application code.
- include/arch/*/ (PUBLIC)
This directory contains the public headers that provide public
architecture-specific definitions which can be referenced by both
kernel and application code.
2. Split arch_interface.h into "kernel-to-arch interface" and "public
arch interface" divisions.
- kernel/include/kernel_arch_interface.h
* provides private "kernel-to-arch interface" definition.
* includes arch/*/include/kernel_arch_func.h to ensure that the
interface function implementations are always available.
* includes sys/arch_interface.h so that public arch interface
definitions are automatically included when including this file.
- arch/*/include/kernel_arch_func.h
* provides architecture-specific "kernel-to-arch interface"
implementation.
* only the functions that will be used in kernel and arch source
files are defined here.
- include/sys/arch_interface.h
* provides "public arch interface" definition.
* includes include/arch/arch_inlines.h to ensure that the
architecture-specific public inline interface function
implementations are always available.
- include/arch/arch_inlines.h
* includes architecture-specific arch_inlines.h in
include/arch/*/arch_inline.h.
- include/arch/*/arch_inline.h
* provides architecture-specific "public arch interface" inline
function implementation.
* supersedes include/sys/arch_inline.h.
3. Refactor kernel and the existing architecture implementations.
- Remove circular dependency of kernel and arch headers. The
following general rules should be observed:
* Never include any private headers from public headers
* Never include kernel_internal.h in kernel_arch_data.h
* Always include kernel_arch_data.h from kernel_arch_func.h
* Never include kernel.h from kernel_struct.h either directly or
indirectly. Only add the kernel structures that must be referenced
from public arch headers in this file.
- Relocate syscall_handler.h to include/ so it can be used in the
public code. This is necessary because many user-mode public codes
reference the functions defined in this header.
- Relocate kernel_arch_thread.h to include/arch/*/thread.h. This is
necessary to provide architecture-specific thread definition for
'struct k_thread' in kernel.h.
- Remove any private header dependencies from public headers using
the following methods:
* If dependency is not required, simply omit
* If dependency is required,
- Relocate a portion of the required dependencies from the
private header to an appropriate public header OR
- Relocate the required private header to make it public.

Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).
Go for the most common style:
- Indent properties with a single tab, including for choices.
Properties on choices work exactly the same syntactically as
properties on symbols, so not sure how the no-indentation thing
happened.
- Indent help texts with a tab followed by two spaces
- Put a space between 'config' and the symbol name, not a tab. This
also helps when grepping for definitions.
- Do '# A comment' instead of '#A comment'
I tweaked Kconfiglib a bit to find most of the stuff.
Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.

Handle this corner case with TCP connection closing:
1) Client A connects, it is accepted and can send data to us
2) Client B connects, the application needs to call accept()
before we will receive any data from client A to the application.
The app has not yet called accept() at this point (for
whatever reason).
3) Client B then disconnects and we receive FIN. The connection
cleanup is a bit tricky as the client is in half-connected state
meaning that the connection is in established state but the
accept_q in socket queue contains still data which needs to be
cleared.
4) Client A then disconnects, all data is sent etc
The above was not working correctly as the system did not handle the
step 3) properly. The client B was accepted in the application even
if the connection was closing.

Use the newest version of the OpenThread project, as updated in
https://github.com/zephyrproject-rtos/openthread/pull/2.
Introduce the following fixes along with the update (they're squashed to
retain bisectability of OT samples):
* Update configs and flags used
Some OT configs were renamed, some new were introduced that Zephyr port
needs to set.
* Add entropy platform driver
OpenThreads `random` platform subsystem was replaced with `entropy`
subsystem which is supposed to serve as an entropy source for the
generic OpenThread's random generator.
* Halt OT thread when OT command is processed
OpenThread can currently be processed from two threads - a
genuine OpenThread thread and shell thread, which processes CLI
commands. This could cause trouble, when context was switched
during OT command processing (i.e. switched to process an incomming OT
message, while still in unfinished command handler).
In result, it was not possible to turn the commissioner role on via
CLI, as the commissioner petition response was handled before the
Commissioner::Start function finished its execution (if the
petitioner is also the network leader, all messages are passed
internally within the stack).
Fix this by suspending the OT thread for the time of an OT command
processing.

Since TCP needs to be able to decide how much data is to be sent
in a TCP segment and when the segment needs to be sent, the TCP
data buffer needs to be passed down to the TCP stack. For tcp2
this causes a new function handling the data as a buffer or as an
iov to be implemented and only that function is called when
sending data out via the new TCP stack. net_tcp_send_data() is

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.

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

Formatting a float32/64 value for plain text is broken.

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

- Every single object that can have multiple instances is using
memset to initialize static resource data during init. This data

statements are unneeded.
- Instead of using memset during object init which is only called
one time during kernel startup, let's add a memset to the
object create function to ensure the resource data is cleared out.
It could have been used prior and then released via a DELETE op.

LwM2M allows for multiple instance resources such the power source
resources in the device object. These types of resources have
always been very hard to work with, and frankly were poorly
implemented.
This led to other issues where it was very hard to have
non-sequential resource instances, and each resource of this type
needed special getter / setter methods such as:
lwm2m_device_add_pwrsrc()
lwm2m_device_set_pwrsrc_voltage_mv()
Going forward, as more LwM2M objects are implemented this just
doesn't scale well.
To fix this:
- split the resource instance data out from the resource data.
This includes the data pointer information and resource
instance id.
- add resource id and resource instance id to the event callback
functions so user's can see in more detail what resources and
resource instances are being handled.
- allow generic functions like lwm2m_engine_get_*() and
lwm2m_engine_set_*() to access resource instance data.
- adjust object resource initialization macros to map resource
instances to resources at the time of object instance
creation.
- fix up the lwm2m_client as a reflection of all of these changes.

Having a checksum of zeros in UDP means "missing checksum" and is a

"An all zero transmitted checksum value means that the transmitter
generated no checksum (for debugging or for higher level protocols
that don't care)."
Such support is made possible by adding a new Kconfig option named
CONFIG_NET_UDP_MISSING_CHECKSUM.
However, that is valid only for IPv4. For IPv6, see the RFC 2460

Calling functions like `net_if_start_dad`, `join_mcast_nodes` or
`net_if_start_rs` lead to L2 API function calls, which is not correct

There were various flaws in it that motivated its removal:
- No hash collision handling mechanism. In case that would happen, the
behavior of the network connection would be unknown. This is the main
drawback
- The lookup is not that much more efficient than the default one. The
only difference of gain is in connection comparison (a u32t comparison
vs a full connection compare). But the list handling is the same. It's
made worse by the presence of a negatives match array which can be
easily filled in and becomes then fully usless, appart from consuming
CPU. As well as adding a new connection: it requires the whole cache
to be cleared which is unefficient.
- Not memory efficient, even compared to a proper hash table.
Two arrays instead of one etc...
All of this could be fixed by using a proper hash table, though it
remains to be seen if such object could fit in Zephyr core.

unicast to the server, the server will drop such packets.
Fix this issue by explicitely specifying what source IP address is

used in multicast addresses. The source address in the other
unicast cases is identical to the 'ciaddr' in the DHCP message.

"It's a Trap!" -- Admiral Ackbar
When moving to the BSD-socket APIs, the original thread running LwM2M
periodic services such as observes and lifetime updates, was replaced
with a re-occuring workqueue job. To save the overhead of creating a
new thread, I used the system workqueue for these jobs.
This was a mistake. If these jobs hit a semaphore or wait for some
reason, it cannot be prempted due to the priority of the system work
queue.
Let's instead add this service handling to the thread that we already
use for polling sockets. This also removes a configuration issue where
the system workqueue stack size needed to be increased. This can now
be adjusted via the LWM2M_ENGINE_STACK_SIZE knob.

The network packet ref count was not properly increased when
the TCP was retried. This meant that the second time the packet
was sent, the device driver managed to release the TCP frame even
if we had not got ACK to it.
Somewhat long debug log follows:
The net_pkt 0x08072d5c is created, we write 1K data into it, initial ref
count is 1.
net_pkt_write: pkt 0x08072d5c data 0x08075d40 length 1024
net_tcp_queue_data: Queue 0x08072d5c len 1024
net_tcp_trace: pkt 0x08072d5c src 5001 dst 5001
net_tcp_trace: seq 0x15d2aa09 (366127625) ack 0x7f67d918
net_tcp_trace: flags uAPrsf
net_tcp_trace: win 1280 chk 0x0bea
net_tcp_queue_pkt: pkt 0x08072d5c new ref 2 (net_tcp_queue_pkt:850)
At this point, the ref is 2. Then the packet is sent as you see below.
net_pkt_ref_debug: TX [13] pkt 0x08072d5c ref 2 net_tcp_queue_pkt():850
net_tcp_send_data: Sending pkt 0x08072d5c (1084 bytes)
net_pkt_unref_debug: TX [13] pkt 0x08072d5c ref 1 (ethernet_send():597)
Ref is still correct, packet is still alive. We have not received ACK,
so the packet is resent.
tcp_retry_expired: ref pkt 0x08072d5c new ref 2 (tcp_retry_expired:233)
net_pkt_ref_debug: TX [10] pkt 0x08072d5c ref 2 tcp_retry_expired():233
net_pkt_unref_debug: TX [10] pkt 0x08072d5c ref 1 ... (net_if_tx():173)
net_pkt_unref_debug: TX [10] pkt 0x08072d5c ref 0 ... (net_if_tx():173)
Reference count is now wrong, it should have been 1. This is because we
did not increase the ref count when packet was placed first time into
sent list in tcp.c:tcp_retry_expired().
The fix is quite simple as you can see from this commit.

This patch fixes following issues.
* If IPv6 neighbor table is full, stack can not add any new
neighbors. So stale counter is introduced. Whenever neighbor
enters into STALE state, stale counter will be incremented
by one. When table is full and if stack wants to add new
neighbor, oldest neighbor in STALE state will be removed
and new neighbor will be added.
* When neighbor is in PROBE state and when it exceeds max
number of PROBEs, only neighbor with router is removed.
As per RFC 4861 Appendix C, entry can be discarded. Now
neighbor will be removed from the table.
* Reachability timer has an issue. e.g. if a first entry timer
is 10 seconds, after 3 seconds, a new entry added with
only 3 seconds. But current implementation does not check
whether remaining time of current left over timeout is more
than new entry timeout or not. In this example, when new entry
timeout is 3 seconds, left over timeout from first etnry is
still 7 seconds. If k_delayed_work_remaining_get() returns
some value then new entry time out was not considered.
Which is bad. It fixed now.
* nbr_free is used sometimes to remove the neighbor. Which does
not remove route if that particulat neighbor is route to some
other neighbor. net_ipv6_nbr_rm() should be used in such places.
* Trivial changes which does not affect functionality.

TCP context is now created with refcount of 2, signifying that it's

TCP context is effectively owned by both application and the stack:
stack may detect that peer closed/aborted connection, but it must
not dispose of the context behind the application back. Likewise,
when application "closes" context, it's not disposed of immediately,
there's yet closing handshake for stack to perform.
This effectively means that TCP contexts have refcount of 2 when
they're created. Without this change, following situation is
possible: peer opens connection, an app get a context (or socket)
via accept, peer sends data, closes connection. An app still holds
a reference to connection, but stack may dispose of context, and
even reuse it for a new connection. Then application holds a reference
to either free, or completely different context.

'_k_' with 'z_'
'_K_' with 'Z_'
'_handler_' with 'z_handl_'
'_Cstart' with 'z_cstart'
'_Swap' with 'z_swap'
This renaming is done on both global and those static function names

are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.

subsys/net/lib/lwm2m/Kconfig.ipso is 'source'd within an 'if LWM2M', in

The 'depends on NET_IPV4' and 'depends on NET_L2_OPENTHREAD' are within
corresponding 'if's in the same file.
'if FOO' is just shorthand for adding 'depends on FOO' to each item

"conditional includes" in Kconfig, so 'if FOO' has no special meaning

- differentiating actual "fragment" to buffer element from a net_pkt

It's more efficient that way, as we use already allocated fragment
buffer instead of reallocating/deallocating after each fragment

A possible optimization would be to calculate the actual size + header

Initial implementation of IPSO Timer object #3340
Based on: http://www.openmobilealliance.org/tech/profiles/lwm2m/3340.xml
"This IPSO object is used to time events and actions, using patterns
common to industrial timers. A POST to the trigger resource or On/Off
input state change starts the timing operation, and the timer
remaining time shows zero when the operation is complete. The
patterns supported are One-Shot (mode 1), On-Time or Interval
(mode 2), Time delay on pick-up or TDPU (tmode 3), and Time Delay
on Drop-Out or TDDO (mode 4). Mode 0 disables the timer, so the output
follows the input with no delay. A counter is provided to count
occurrences of the timer output changing from 0 to 1. Writing a value
of zero resets the counter. The Digital Input State resource reports
the state of the timer output."

pkt->buffer is represented by 1+ net_buf. If some are unused, this will
deallocates them.
This situation can happen on TCP where net_pkt allocator evaluates the
header size to its maximum size. Which space might not be (fully) used
in the end. On fixed data size buffer, this might end up by having last
buffer(s) not bein used. So better removing those.

DNS callback needs "struct shell *shell" data structure to pass as
a parameter to shell print. How it was achieved previously is that
it was packaged together with cosmetic "bool first" param into
"struct net_shell_user_data" on the stack, and passed to the
callback. The problem was that the original command handler then
returned, so the "struct net_shell_user_data" on the stack was
overwritten, and the callback crashed on accessing it.
An obvious solution was to make that structure static, but that would
leave to issues still, as turns out we allow system shell to be run
as more than one concurrent instances.
Next solution was to keep this structure on the stack, but block the
command handler until callback is finished. However, that hit a
deadlock due to not well thought out use of a mutex in the shell
printing routines.
The solution presented here is due to @nordic-krch, who noticed that
"bool first" param is indeed cosmetic and not really required. Then
we have only "struct shell *shell" to pass to the callback, and can
do that in callback's pointer param directly, ditching
"struct net_shell_user_data" which needs to be stored on the stack.

This commit adds packet socket support to socket api.
This version supports basic packet socket features.
Protocol family is AF_PACKET, type of socket is
SOCK_RAW and proto type is ETH_P_ALL. The user will
receive every packet (with L2 header) on the wire.
For TX, the subsystem expects that the user has set
all the protocol headers (L2 and L3) properly.
Networking subsystem doesn't verify or alter the headers while
sending or receiving the packets. This version supports packet
socket over Etherent only. Also combination of other family
and protocols doesn't work (i.e. Application can not open
packet-socket and non packet-socket together).

As we are adding more protocol families and protocol types
to connection handlers, some values might be same across
different types. Current connection handler only stores
proto type to match the handler, which is not enough if
we add more types. Also combination of family and types
may vary too. So adding family to connection handler to
figure out best match.

In case of Ethernet, if the requested size is larger than MTU and if
AF_UNSPEC is provided, the allocator will need to take into account
the ethernet header size which is not accounted in the MTU.
Other current L2 do not follow that rule as their MTU is based on IP
one (IPv6 most of the time). What they declare as MTU is the full frame
size they handle (minus the FCS for instance in 15.4). So with
AF_UNSPEC, such assumption on L2 header size is unrelevant.
(On 15.4 the header size is variable anyway and cannot be known until
the frame is parsed).

Result is instead of segfaulting on r/w access, these operations will
bail out properly. Subsequent, and logical (unless you have a leak
which is another issue) net_pkt_unref will tell you who/where the pkt
was freed. Without it, you will get a segfault for instance, but that
