Compiling an application with CONFIG_NET_ZPERF=y leaving
CONFIG_ZPERF_WORK_Q_THREAD_PRIORITY at its default value would
systematically cause a kernel panic during thread initialization.
The Kconfig variable is NUM_PREEMPT_PRIORITIES by default. Application
threads may not define a priority lower than NUM_PREEMPT_PRIORITIES - 1,
though.
This change limits zperf's thread priority to a valid range. It does not
change the default value as it makes sense to default the thread
priority to the lowest possible value (which is NUM_PREEMPT_PRIORITIES)
but Kconfig does not allow for arithmentic. So the combination of
CLAMP() plus the Kconfig default will ensure min priority plus limit the
range to valid values no matter what has been defined as priority in
Kconfig.

In order to support external IP stacks that might have Connection
ID support, the LwM2M engine should allow client to bypass default
behaviour.
New set_socketoptions() callback added into client context
that allows overriding all socket opetions. This is called
after a socket is opened, but before the connect() is
called. This cannot be combined with load_credentials() callback
on all platforms as for example nRF91 requires modem offline
when credentials are written. This would cause socket to be closed
as well.
Second change is that we allow fine tuning of what we do with
socket handle when QUEUE mode is enabled and engine enters idle
state.
First option would be to close the socket. That would cause
TLS Alert(Close Notify) to be send. This is a band choice if
LTE modem was already in PSM or eDRX power saving mode.
Second option would be to delay socket closing until we
are going to send LwM2M update. There TLS Alert is also send,
but most probably lost due to NAT mapping timed out. This
is a best choice for LTE modem with DTL session cache enabled.
Two new options are to keep socket open, and either stop listening
or just keep listening. Both of these options work fine when
we have DTLS Connection ID support.

In case lwm2m_socket_start() internal error, it should only do cleanup
on the socket, i. e. call lwm2m_socket_close(), not lwm2m_engine_stop().
The latter resets the entire lwm2m_context, which results in removal of
active observations.
This should not be done, as it collides with the RD client logic, where
connection resumption may skip the full registration phase, in result
not notifying the server that it should restart the observations.
At the same time, the RD client should clean the lwm2m_context when it's
done trying to update the registration and proceeds with regular
registration/bootstrap in the network error handler. In that case, only
the socket was closed, so the lwm2m_context needs to be reset
separately.

In order to allow the TLS accept() call to be interrupted, it should

The accept() so far would block with mutex held, making it impossible to
interrupt it from another thread when the socket was closed.
Fix this, by reusing the condvar mechanism used for receiving. It's OK
to use the same routine, as underneath accept() is monitoring the same
FIFO as recv().
Additionally, simplify k_fifo_get() handling in accept() - as the
waiting now takes place on condvar, it can be used in a non-blocking
manner. Blocking accept() call should not reach this place if there's no
new incoming connection waiting on the FIFO.

Installing recv callback with net_context_recv() after
net_context_connect() left an opening for a possible race - in case the
server send some data immediately after establishing TCP connection, and
Zephyr did not manage to install the callback on time, the data would be
lost, corrupting the stream.
This can be avoided, by installing the recv callback before the
connection is triggered. As net_context_recv() called w/o timeout only
registers the callback function, it should have no negative impact. The
only change on the TCP side is when the connection is closed - in case
TCP is in connect stage, do not call the recv callback (before this
change it'd be NULL at that point).

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

Provide a means of declaring zero or more HTTP services, each

Static HTTP resources are those which have fixed paths[1] which
are known prior to system initialization. Some examples of
static http resources would be
* a forwarder from '/' to '/index.html'
* a REST endpoint with fixed path '/api/foo' and detail
pointing at some implementation-specific function
* a Javascript file in string form with fixed path '/js/util.js'
* a 'construction' image with path '/res/work.png'
* a gzip-compressed 'Hello' HTML file at '/hello.html'
Without describing in any detail how static HTTP resources are
organized or served by any given HTTP server, we can describe
what static resources exist on a system in a common way that
does not require any optional facilities (e.g. filesystem) and
relies only on addressable memory.
Additionally, for the purposes of simply allowing others
to implement custom HTTP servers in a consistent way, or
benchmarking implementations, or having a consistent testsuite
to use across multiple implementations, it is helpful to have
a common method to declare HTTP services and static resources
for Zephyr.

When we have establised an DTLS handshake and try LwM2M Update,

Currently, if timeout is not configured for the network initialization in
the config module, the initialization function will configure IPv4/IPv6/
DHCPv4 regardless of the interface status. This is not the case when the
timeout is set, and the interface was not brought up during the timeout
period. This lead to ambiguity in terms of interface initialization.
This commits unifies the behaviour between these two cases. The
aforementioned initializations will always take place, regardless of the
interface status. The IPv4/IPv6 and DHCPv4 routines should be prepared
to deal with interfaces that are not brought up. The only difference
now, between timeout and no timeout scenario, is that the former will
report an error in case the timeout occurs wile waiting for the expected
events.

`sntp_simple()` was forcing to resolve SNTP-server's URL into IPv4 address
addresses. This was not allowing sntp_init() to succeed in case the system
did not support IPv4 addresses (returning EPFNOSUPPORT, ie. Protocol
Family error).
Now by default SNTP has unspecified family type and it relies on
`net_getaddrinfo_addr_str()` to be able to resolve literal server URLs
into the supported IP family type.

Setting `hints.ai_family` to `AF_UNSPEC` was causing
`net_getaddrinfo_addr_str()` and in turn `getaddrinfo()` to resolve the
literal SNTP SERVER first into IPv4 and then (if supported) IPv6 addresses.
This was causing useless waste of time and memory in case IPv4 was not
supported. In addition, in case IPv4 addresses were not supported, other
system components (eg. SNTP) could fail due to the DNS returning IP
addresses with unsupported family type (ie. IPv4).
Now, if address family is not explicitly set to `AF_INET` (ie. IPv4), then
no attempt is made to resolve SNTP server address into an IPv4 address.

The net_core:process_data() and connection:net_conn_input() methods are
the central network packet reception pipeline which:
1) guide network packets through all network layers,
2) decode, validate and filter packages along the way and
3) distribute packages to connections/sockets on all layers.
This code seems to have grown complex and rather cluttered over time as
all protocols, layers and socket implementations meet there in one single
place.
The code also reveals its origin as a pure IP stack which makes it hard
to introduce non-IP protocols and their supporting socket infrastructure
in a modularized way.
For an outside contributor it seems almost impossible to add another
protocol, protocol layer, filter rule or socket implementation without
breaking things.
This change doesn't try to solve all issues at once. It focuses
exclusively on aspects that maintain backwards compatibility:
* Improve modularization and encapsulation on implementation level by
disentangling code that mixes up layers, protocols and socket
implementations.
* Make IP just one protocol among others by removing assymmetry in
protocol handling logic and introduce preprocessor markup so that
IP-specific code can be eliminated by the preprocessor if not needed.
* Use preprocessor markup to delineate hook points for future
modularization or expansion without introducing structural changes (as
this would almost certainly break the API).
* Reduce cyclomatic complexity, use positive rather than negative logic,
improve variable naming, replace if/elseif/else blocks with switches,
reduce variable span, introduce inline comments where code does not
speak for itself, etc. as much as possible to make the code overall

Introducing additional socket implementations is rather involved right
now due to some more or less convoluted code that had grown over time.
This change introduces an additional configuration variable in preparation
for additional socket API drivers. The idea is to reduce redundant code
and make existing code more readable by better exposing its actual intent.

The code contained several repeated composite IPv4/v6 and UDP/TCP
preprocessor statements that can be simplified by introducing a hidden
NET_IP preprocessor constant that captures what probably is actually
"meant" by this code.
While we were on it we also used the new constant to further isolate
IP-specific code from non-IP specific generics.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

This new implementation of pipes has a number of advantages over the
previous.
1. The schedule locking is eliminated both making it safer for SMP
and allowing for pipes to be used from ISR context.
2. The code used to be structured to have separate code for copying
to/from a wating thread's buffer and the pipe buffer. This had
unnecessary duplication that has been replaced with a simpler
scatter-gather copy model.
3. The manner in which the "working list" is generated has also been
simplified. It no longer tries to use the thread's queuing node.
Instead, the k_pipe_desc structure (whose instances are on the
part of the k_thread structure) has been extended to contain
additional fields including a node for use with a linked list. As
this impacts the k_thread structure, pipes are now configurable
in the kernel via CONFIG_PIPES.

There is a potential, corner case scenario, where a deadlock can occur
between TCP and socket layers, when both ends of the connection transmit
data.
The scenario is as follows:
* Both ends of the connection transmit data,
* Zephyr side send() call gets blocked due to filing the TX window
* The next incoming packet is data packet, not updating the RX window
on the peer side or acknowledging new data. The TCP layer will
attepmt to notify the new data to the socket layer, by calling the
registered callback. This will block the RX thread processing the TCP
layer, as the socket mutex is already acquired by the blocked send()
call.
* No further packets are processed until the socket mutex is freed,
which does not happen as the only way to unblock send() is process
a new ACK, either updating window size or a acknowledging data.
The connection stalls until send() times out.
The deadlock is not permament, as both threads get unlocked once send()
times out. It effectively breaks the active connection though.
Fix this, by unlocking the socket mutex for the time the send() call is
idle. Once the TCP layer notifies that the window is available again,
the mutex is acquired back.

By default, any string or opaque data that LwM2M engine initializes
sets data lenght to same value as given buffer length for that
resource.
However, on run time, engine keeps track how much data is written
to each resource, so when reading from any resource, should only
return data that has been written there. But uninitialized resources
return the content of the whole buffer.
Fixed the problem by introducing macros INIT_OBJ_RES_LEN(),
INIT_OBJ_RES_MULTI_DATA_LEN() and INIT_OBJ_RES_DATA_LEN() that
allows you to give the amount of data existing in buffer when
the resource is initialized. This sets the data_len and max_data_len
variables correctly.
Also introduced new functions lwm2m_engine_get_res_buf() and
lwm2m_engine_set_res_buf() that distinct between data size and

Fragmented data passed to sendmsg() should be sent as a single datagram in

for stream sockets.
There is no mbedTLS API for 'gather' write at this moment. This means that
implementing sendmsg() would require allocating contiguous memory area at
Zephyr TLS socket level and copying all data fragments before passing to
mbedTLS library. While this might be a good option for future, let's just
check if data passed to sendmsg() API consists of a single memory region
and can be sent using single send request. Return EMSGSIZE error if there

Introduce TLS socket options, which allow to configure session caching
on a socket.
The cache can be enabled on a socket with TLS_SESSION_CACHE option.
Once cache is enabled on a socket, the session will be stored for re-use
after a sucessfull handshake. If a socket is attempting to connect to a
host for which session is stored, the session will be resumed and mbed
TLS will attempt to use a simplified handshake procedure.
The server-side management of sessions is fully controlled by mbed TLS
after session caching is enabled on a socket.
The other TLS_SESSION_CACHE_PURGE option allows to clear all of the
cache entries, releasing the memory allocated for sessions.

In some cases (for examples when offloaded socket implementation does
not implement TLS functionality) it could be desired to create a native
TLS socket with an underlying offloaded socket.
This cannot be achieved with SO_BINDTODEVICE option only, as TLS socket
type is not really associated with a particular interface - it either
has to be offloaded, or a fully native socket is created (native TLS on
a native interface).
In order to address the problem, introduce TLS_NATIVE socket option.
This option instructs the socket dispatcher layer to create a native TLS
socket. As with the socket dispatcher the underlying socket
implementation is not decided during TLS socket creation, therefore it's
possible to use SO_BINDTODEVICE to choose either native or offloaded
interface for the underlying socket.
Additionally remove NET_SOCKETS_OFFLOAD_TLS Kconfig option, as it's no
longer needed with an runtime option to select whether to offload TLS or
not.
Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>
Add an intermediate socket implementation called socket dispatcher. This
layer can be used along with the socket offloading, to postpone the
actual socket creation until a first operation on a socket is executed.
This approach leaves an opening to bind a socket to a particular
offloaded network interface, and thus offloaded socket implementation,
using SO_BINDTODEVICE socket option. Thanks to this, it is now possible
to use multiple offloaded sockets implementations along with native
sockets, and easily select which socket should use with network
interface (even if it's an offloaded interface).

added to track how many bytes were actually sent to the network.
* http_flush_data() forwarded the return value of sendall() helper
function. That function however did not return number of bytes sent,
but 0 or a negative error code.

So far close() was called on underlying socket when timeout has expired.
This is wrong in several ways. First of all POSIX specification of
close() does not specify what should happen on blocking recv() call and
different systems have different behaviors (e.g. Linux does not wake up
recv() caller if there was no new incoming data, while other systems
might wakeup recv() caller immediately). Another (and much more severe)
problem is that HTTP client user does not know whether underlying socket
was already closed or not after HTTP request has finished. As a result
it was not clear whether close() should be called by HTTP client user.
Use shutdown(..., SHUT_RD) in internal HTTP client implementation, so
that recv() is woken up immediately with 0 as result (which means EOF).
This will allow to gracefully handle timeouts and make it clear that it
is application responsibility to always call close() after HTTP
request (successful or not).

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().

processed in a sequence, allowing to find appropriate socket

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

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.

obsolete since more detailed flags were added. This commit removes the
flag and references to it altogether.

Fix `poll()` handling for DTLS clients when the underlying socket is an
offloaded socket. As in this case no `k_poll()` is used underneath, it's
not possible to monitor the handhshake status with `tls_established`
semaphore. Instead, do the following:
1. If no handhshake is in progress yet, just drop the incoming data -
it's the client who should initiate the handshake, any data incoming
before that should not be processed.
2. If handshake is currently in progress, lift the `POLLIN` flag and add
small delay to allow the other thread to proceed with the handshake.
3. Otherwise, just proceed as usual.

The TLS/DTLS handshake in most cases is a blocking process, therefore
the underlying socket should be in a blocking mode to prevent busy
looping in the handshake thread. Fix this by clearing the O_NONBLOCK
flag on the underlying socket before the handshake, and restoring it
afterards.

`OT_LOG_LEVEL_NONE` has some uses within OpenThread but it is not

use of those logs as `LOG_LEVEL_ERR` level.

When zsock_close() is called, socket is freed before the mutex for the
socket is unlocked. If the freed socket is given to another thread
immediately, the mutex for the socket will be initialized by the new
socket owner, while the mutex is still locked by the thread calling
zosck_close().

Instead of manually computing payload offset, let the CoAP library do
the work, and use the payload pointer returned by the
`coap_packet_get_payload()` function instead.
Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>
The function did not work correct for packets generated with Zephyr
APIs, as `max_len` holds the entire buffer size, not the actual packet
size.
Additionally, unify how Payload Marker is handled in the calculation -
currently the coap parsing function adds it to the `opt_len` field,
which is counter-intuitive.
Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>
It is important that offset is set in the same manner, regardless of the
origin packet - it should indicate the final packet length in both
cases, when the packet is generated on the Zephyr side with CoAP APIs,
and when it's parsed from the UDP datagram. This allows for functions
like `coap_packet_get_payload()` to work correcty in both cases.

Rename `write_signal` to `readable` and `read_signal` to `writeable`
which are more meaningful to the actual states they represent, and make
the code analysis easier.
Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>
In case read or write were called before the actual poll() call, the
poll() function was not signalled correctly about such events, which in
order could lead to a deadlock if the poll() was called with infinite
timeout.

- bugfix: Accept initial tftp server reply from a port different than
the one used to establish the connection (typically 69) as mandated
by RFC 1350. Previous implementation was not standard compliant.
- bugfix: close socket in case of error or timeout.
- bugfix: Reset retransmit counter after receipt of a good packet.
- bugfix: Use CONFIG_TFTP_LOG_LEVEL to set log level.
- api: upon successful receipt of the file set `client.user_buf_size`
to the size of the file received.
- Restructure the code, comments.
- Limit usage of global variables.
- Limit usage of `goto`.
