sock_udp_recv_buf_aux() sometimes will return -ETIMEDOUT before
the given timeout has expired (e.g. 28798µs instead of 160000µs).
This messes with many assumptions and breaks protocols that rely
on the timeout.
Until we have a proper fix, add this workaround.

A border router should not send router advertisements on it's 6LoWPAN
interfaces, but if it also has classic IPv6 downstream interfaces it
should very much do so.
19881: drivers/stmpe811: fix initialization if callback function parameter is NULL r=benpicco a=gschorcht
### Contribution description
This PR fixes the `stmpe811` driver initialization if the callback function parameter `cb` is `NULL. This might be the case for example if the application uses the touch device in polling mode.
If the interrupt pin is initialized if the callback function parameter `cb` is `NULL`, the driver crashes the first time an interrupt is triggered. Therefore, the INT pin must be initialized only if also the callback function parameter `cb` is not `NULL`.
To be able to test the polling mode, this PR also includes a change of the `tests/drivers/stmpe811` application which introduces the environment variables `STMPE811_POLLING_MODE` `STMPE811_POLLING_PERIOD` and in the makefile.
### Testing procedure
1. Use a `stm32f429i-disc1` board and test it in polling mode:
```
STMPE811_POLLING_MODE=1 BOARD=stm32f429i-disc1 make -C tests/drivers/stmpe811 flash term
```
It should work as expected.
```
main(): This is RIOT! (Version: 2023.10-devel-119-g26e7a-drivers/stmpe811_fix_cb_null)
STMPE811 test application
+------------Initializing------------+
Initialization successful

2. Checkout master branch and cerry-pick commit 691a5e6308426ddc685e5a2c297238529211c258. The test application `tests/drivers/stmpe811` will crash once a touch event occur:

19892: pkg/tinydtls: allow to set buffer size from application again r=benpicco a=leandrolanzieri
### Contribution description
Currently the buffer size on tinydtls is set in its Makefile whenever `gcoap` module is present. This limits the ability of the user to override the value. This adds a pre-check of the `CFLAGS` to see if it was set before.
### Testing procedure
Try setting `CFLAGS += -DDTLS_MAX_BUF=<some_value>` on `examples/gcoap_dtls`, you should be able to override the default value without errors.

`clang` doesn't propagate the packed attribute to members. I think
this incorrect, but explicitly adding it won't hurt and makes clang
happy. So let's have it.
19487: nanocoap: implement extended tokens (RFC 8974) r=benpicco a=benpicco
19808: boards: add ESP32-S3-USB-OTG support r=benpicco a=gschorcht
### Contribution description
This PR provides the support for the [ESP32-S3-USB-OTG](https://docs.espressif.com/projects/espressif-esp-dev-kits/en/latest/esp32s3/esp32-s3-usb-otg/user_guide.html) board.
The SD card can only be used in SPI mode at the moment. As soon as PR #19786 is merged, the SD/MMC support can be enabled and the SD card can then be used in SD mode with 4-bit data bus width.
The display uses uses the ST7789 driver IC that is compatible with the ST7735. For that purpose the ST7735 driver is extended by a pseudomodule definition `st7789` for the ST7789 which is enabled by the board and enables automatically the `st7789` (e57c48a33ee2a869c15603788e5306ba066f91cf). Vise versa, board's `Makefile.dep` enables automatically the `st7789` pseudomodule if the `st7735` is used. The pseudomodule `st7789` is just used to increase the upper limit for supported lines. This change is also part of PR #19807.
~The PR includes a very small documentation fix for ESP32-S3-DevKit board that was noticed during the development of this board definition (1155b6ac1b8efa39d8a0bd7150e602095159fdc1).~
### Testing procedure
The board has been tested with all basic tests for supported hardware including `tests/driver/st3375`:
- [x] tests/drivers/st3375
- [x] tests/periph/gpio
- [x] tests/periph/pwm
- [x] tests/periph/spi
- [x] tests/periph/uart

19733: cpu/msp430: reorganize code r=maribu a=maribu
### Contribution description
RIOT supports two distinct families of the MSP430: The [MSP430 x1xx] MCU family and the [MSP430 F2xx/G2xx] MCU family. For both incompatible MCU families the code was located in the msp430fxyz folder, resulting in case of the UART driver in particularly bizarre code looking roughly like this:
```C
#ifndef UART_USE_USCI
/* implementation of x1xx peripheral ... */
#else
/* implementation of F2xx/G2xx peripheral ... */
#endif
/* zero shared code between both variants */
```
This moves peripheral drivers shared between the two families to msp430_common and splits the SPI and UART driver into two MCU families.
In addition, it cleans up the `msp430_regs.h` by dropping most of it and using the macros and symbols provided by the vendor header files. There is little reason for us to maintain constants when TI is already doing that.

19769: cpu/nrf53: add initial support with nRF5340DK-APP board r=maribu a=dylad
### Contribution description
This PR adds support for nRF5340 MCU and its associated Nordic development board, nRF5340DK.
This MCU provides a dual Cortex-M33, one application core running at up to 128MHz, and one network core running at up to 64MHz.
Peripherals are inherited from others Nordic MCUs families so it shouldn't be hard to add more of them in followup PRs.
For now, only the minimal set of peripherals is supported:
- GPIO / GPIO_IRQ
- UART
- TIMER
### Testing procedure
Build the usual test application for the supported peripherals and flash the board.
nRF5340DK provides two serial ports on its embedded debugger. RIOT's shell should be available on the first one (/dev/ttyACM0)

Checking for overflow of integer addition by comparing against one of
the arguments of the addition does not work when the result of the
addition is automatically promoted to a larger type.
Fix by using an explicit cast to make sure that the result of the
addition is not implicitly converted to a larger type.

19618: cpu/stm32: fix riotboot settings for L4 and WB r=benpicco a=gschorcht
### Contribution description
This PR fixes the `riotboot` configuration for L4 and WB.
The family is not called `stm32l4` or `stm32wb` but `l4` and `wb`. That is, the `riotboot` configuration didn't work at all. Furthermore, a minimum `RIOTBOOT_LEN` of `0x2000` is required for L4.
Found when investigating the compilation errors for `bootloaders/riotboot_serial` in PR #19576.
### Testing procedure
1. Green CI.
2. Use the following commands:
```
BOARD=nucleo-l496zg make -C tests/riotboot info-debug-variable-RIOTBOOT_HDR_LEN
BOARD=p-nucleo-wb55 make -C tests/riotboot info-debug-variable-RIOTBOOT_HDR_LEN
```
In master these commands give
```
0x400
```
With this PR these commands give
```
0x200
```
as expected.
3. Use the following commands:
```
BOARD=nucleo-l496zg make -C tests/riotboot info-debug-variable-RIOTBOOT_LEN
BOARD=p-nucleo-wb55 make -C tests/riotboot info-debug-variable-RIOTBOOT_LEN
```
In master these commands give
```

```
With this PR these commands give
```

```
as expected.

19581: cpu/samd5x: enable FDPLL1 at 200MHz r=benpicco a=dylad
### Contribution description
This PR allows to use the second FDPLL (the first one is used to generated the 120MHz frequency used by the core and some peripherals). The second FDPLL is setup to run at 200MHz which is the maximum allowed by this MCU.
In fact, I reused the existing function which setup FDPLL0 so it can be used in a generic way for both PLL (since they are the same IP).
I change the way the computation offset (left shift by 5) is done because 200MHz << 5 wouldn't fit inside an `uint32_t` and I wanted to avoid using an `uint64_t` here
Two additional commits are present for a small cleanup and a fix.
This is currently unused in our codebase, so it shouldn't impact this platform too much as the `ONDEMAND` bit is set. the FDPLL will not be running out of the box. But `@gschorcht` might need it pretty soon.
### Testing procedure
This PR can be tested on a `same54-xpro` and an oscilloscope using the following the patch:

19527: drivers/sdcard_spi: small cleanup r=benpicco a=gschorcht
### Contribution description
This PR provides a small cleanup:
- the copy of `sdcard_spi_params_t` is removed (commit bfc2a51f70)
- the documentation was changed to fit the 100 characters per line. (commit 36f0162b34)
It is not necessary to hold a complete copy `sdcard_spi_params_t` in the device descriptor. Constant parameters can be used directly from ROM instead. This saves 24 bytes of RAM.
### Testing procedure
Use any board with SD Card SPI interface. The driver test should still work, for example:
```
BOARD=esp32-wrover-kit make -j8 -C tests/driver_sdcard_spi flash term
```
```

18620: core: add core_mutex_debug to aid debugging deadlocks r=maribu a=maribu
### Contribution description
Adding `USEMODULE += core_mutex_debug` to your `Makefile` results in
on log messages such as
[mutex] waiting for thread 1 (pc = 0x800024d)
being added whenever `mutex_lock()` blocks. This makes tracing down
deadlocks easier.
### Testing procedure
Run e.g.
```sh
USEMODULE=core_mutex_debug BOARD=nucleo-f767zi make -C tests/mutex_cancel flash test
```
which should provide output such as
```

19504: cpu/cc26xx_cc13xx: Fix bogus array-bound warning r=maribu a=maribu
### Contribution description
GCC 12 create a bogus array out of bounds warning as it assumes that because there is special handling for `uart == 0` and `uart == 1`, `uart` can indeed be `1`. There is an `assert(uart < UART_NUMOF)` above that would blow up prior to any out of bounds access.
In any case, optimizing out the special handling of `uart == 1` for when `UART_NUMOF == 1` likely improves the generated code and fixes the warning.

### Testing procedure
The actual change is a pretty obvious one-liner, so that code review and a green CI should be sufficient. If not, running any UART example app without regression should do.

19506: tools/openocd: Fix handling of OPENOCD_CMD_RESET_HALT r=maribu a=maribu
### Contribution description
The OPENOCD_CMD_RESET_HALT was not longer correctly passed to the script. This fixes the issue.
### Testing procedure
Flashing of e.g. the `cc2650-launchpad` with upstream OpenOCD should work again.
### Issues/PRs references
The change was added to https://github.com/RIOT-OS/RIOT/pull/19050 after testing the PR and before merging. I'm not sure if the fix never worked because of this, or if behavior of `target-export-variables` or GNU Make changed.

19383: cord: include gcoap_req_send returning 0 in error r=benpicco a=bergzand
### Contribution description
gcoap_req_send returns 0 if it was unable to send the CoAP request. CoRD did not include that case in the return code checks. This changes CoRD to include it and drop the registration if CoAP could not send the request. The old behaviour made the CoRD thread lock up.
### Testing procedure
- Check with the gcoap API docs.
- I can reliable trigger the issue with a RIOT application including both the `cord_ep_standalone` module and some measurement reported both sending requests to the same application. If at some point the application is shut down, gcoap has all its memo's occupied with the measurement reporting and can't add the CoRD update request. Thus the CoRD update request fails with a zero code and the thread (previously) would lock up.

19385: cpu/stm32/periph/timer: fix clobered IRQ flag r=benpicco a=Enoch247
### Contribution description
From the git commit:
> The STM32 periph_timer driver reads the timer's status flags, then clears them all. It is possible that a timer interrupt could occur between reading the flag and clearing it. This would lead to a lost interrupt.
>
> The timer's status flags can be cleared by software, but can only be set by the hardware. This patch takes advantage of this by only clearing the flags it knows are set. The rest of the flags are set, which doesn't actually change their state.
I had trouble finding anything in ST's datasheet saying that software could not set the timer's status flags, but testing showed that this is how it works in practice. Further, [ST's own HAL ](https://github.com/STMicroelectronics/STM32CubeF4/blob/master/Drivers/STM32F4xx_HAL_Driver/Inc/stm32f4xx_hal_tim.h#L1258)confirms this. If the hardware didn't work this way, it would be impossible to atomically read-modify-write the flags.
### Testing procedure
I tested by doing the following:
1. `make -C tests/periph_timer BOARD=nucleo-f767zi all flash term`
2. press s
3. press [ENTER]
4. observe test passes
5. `make -C tests/periph_timer_periodic BOARD=nucleo-f767zi all flash term`

19365: bootloaders: fix bootloader button logic r=benpicco a=dylad
### Contribution description
In lastest master, the `BTN_BOOTLOADER_INVERTED` logic doesn't work as expected.
This PR fixes the underlying logic by replacing the `BTN_BOOTLOADER_INVERTED` macro definition by a runtime function.
In fact the current code:
```
#ifndef BTN_BOOTLOADER_INVERTED
#if (BTN0_MODE == GPIO_IN_PD)
#define BTN_BOOTLOADER_INVERTED false
#else
#define BTN_BOOTLOADER_INVERTED true
#endif
#endif
```
cannot work because both `BTN0_MODE` and `GPIO_IN_PD` are not known by the precompiler as they are enum values defined at cpu level.
Thus, replaces it by a runtime function in our bootloader applications.
I've also add `GPIO_OD_PU` along side `GPIO_IN_PU` and add a new define (which can be override at board level or app level) in case an external pullup is used.
### Testing procedure
Flash the riotboot_dfu bootloader:
`make BOARD=saml21-xpro -C bootloaders/riotboot_dfu flash`
Then, flash any test app:
`PROGRAMMER=dfu-util USEMODULE=usbus_dfu make BOARD=saml21-xpro -C tests/shell riotboot/flash-slot0`
With master, the application will not start.
With this PR, the application will start after flashing.

19119: makefiles/tools/serial.inc.mk: Allow detection of debug adapter r=benpicco a=maribu
### Contribution description
This PR adds the ability to automatically detect the debug adapter for boards with an integrated programmer/debugger, if that debugger also provides the TTY.
This extends the TTY detection that can be enabled with `MOST_RECENT_PORT=1` to set `DEBUG_ADAPTER_ID` to the TTY's serial, but only if `DEBUG_ADAPTER_ID_IS_TTY_SERIAL` is set to `1` by the board (as not all boards have an integrated programmer/debugger).
### Testing procedure
Connect a HiFive-1B and a nRF52840DK at the same time and try `make BOARD=<nrf52840dk|hifive1b> MOST_RECENT_PORT=1 -C examples/default flash term` for both. The programmer will not reliably select the correct programmer in `master`. With this PR, it will.

19295: gcoap: Finish the gcoap_get_resource_list_tl -> gcoap_get_resource_list renaming r=benpicco a=chrysn
### Contribution description
In #16688, an argument was added to the `gcoap_get_resource_list` function by creating a new function `gcoap_get_resource_list_tl` with a deprecation and roll-over plan.
This plan has not been acted on so far.
This PR shortens the original plan by just adding the argument to `gcoap_get_resource_list` and removing `gcoap_get_resource_list_tl` in a single go. The rationale for this deviation is that while it's a public API, its only two practical consumers are the (built-in) well-known/core implementation, and the (built-in) CoRE Resource Directory (cord) endpoint. Moreover, a further change to this API (switching over to `coap_block_slicer_t`) is expected to happen within this release cycle, which would take something like 4 total releases to get through otherwise, which is unrealistic for an API that there are no known external users of.
A second commit clean up ToDo items (in the changed function's documentation) that referred to a IETF draft that has long been abandoned by the CoRE WG.
### Testing procedure
Plain inspection and CI passing should suffice.
### AOB
There is a second analogous pair left over from #16688, `gcoap_req_send` / `gcoap_req_send_tl`. As that *is* expected to be used widely, I prefer not to mix these two concerns, and get the present one through without unnecessary hold-up.

18903: pkg/tinyusb: add tinyUSB netdev driver r=dylad a=gschorcht
### Contribution description
This PR adds the tinyUSB netdev driver.
The tinyUSB netdev driver is part of the tinyUSB package and is enabled by module `tinyusb_netdev`. It is available for boards that provide the `tinyusb_device` feature.
**Please note** Since the tinyUSB package is distinct from (and incompatible with) the USB stack provided around USBUS in RIOT (see USB), the tinyUSB netdev driver cannot be used together with with any USBUS device class.
The tinyUSB netdev driver uses Ethernet over USB and supports the following protocols:
- CDC ECM (Ethernet Control Model)
- CDC NCM (Network Control Model)
- RNDIS (Microsoft Remote NDIS)
While Linux and macOS support all these protocols, Microsoft Windows only supports the RNDIS protocol and since Windows version 11 also the CDC NCM protocol. macOS supports the RNDIS protocol since version 10.15 (Catalina).
Which protocol is used is selected by the corresponding pseudomodules `tinyusb_class_net_cdc_ecm`, `tinyusb_class_net_cdc_ncm` and `tinyusb_class_net_rndis`.
The CDC ECM protocol (`tinyusb_class_net_cdc_ecm`) and the RNDIS protocol (`tinyusb_class_net_rndis`) can be used simultaneously to support all operating systems, for example :
```
USEMODULE='tinyusb_netdev tinyusb_class_net_rndis tinyusb_class_net_cdc_ecm' \
BOARD=... make -C ... flash
```
In this case, the CDC ECM protocol is the default protocol and the RNDIS protocol the alternative protocol defined as second device configuration. The CDC NCM protocol cannot be used together with the CDC ECM or the RNDIS protocol.
This PR includes PR #18983 for now to be compilable.
Comparison with USBUS CDC ECM (`nucleo-f767zi` board):
```
text data bss dec hex filename
65916 596 18728 85240 14cf8 tests_pkg_tinyusb_netdev.elf
```
```
text data bss dec hex filename
63120 544 15444 79108 13504 tests_usbus_cdc_ecm.elf
```
### Testing procedure
Use a board that is supported by tinyUSB. Compile and flash the test application for each protocol:
1. RNDIS
```
BOARD=... make -j8 -C tests/pkg_tinyusb_netdev flash
```
2. CDC ECM
```
CLASS=tinyusb_class_net_cdc_ecm BOARD=... make -j8 -C tests/pkg_tinyusb_netdev flash
```
3. CDC NCM
```
CLASS=tinyusb_class_net_cdc_ncm BOARD=... make -j8 -C tests/pkg_tinyusb_netdev flash
```
For each test, a network interface should be added on the host. Use command `ifconfig` on USB device and on the host and check that both have a link local address. In syslog there should be an output like the following:

19175: drivers/periph_common/flashpage: fix silent error r=benpicco a=Enoch247
### Contribution description
This patch removes a test that silently hides failed writes to NULL. Instead, assert is used to ensure that the address is not NULL.
### Testing procedure
I am not certain how to update the tests to catch asserts. If this is possible, I will add a test, if someone will point me to a good example to learn from.

Revert "sys/pm_layered: pm_(un)block add attribute optimize(3) -shortens hotpath"
This reverts commit 5447203921.
### Contribution description
Compiling `examples/gnrc_networking_mac` using `TOOLCHAIN=llvm` yields the following error:
```
RIOT/sys/pm_layered/pm.c:77:16: error: unknown attribute 'optimize' ignored [-Werror,-Wunknown-attributes]
__attribute__((optimize(3)))
```
As indicated, this is because the attribute `optimize` is GCC only and not present in LLVM.
Compare the manpages of [GCC](https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html) and [LLVM](https://clang.llvm.org/docs/AttributeReference.html).
### Testing procedure
Since this should only affect performance and not behavior, no special testing is needed. I am not aware of any tests in RIOT which could verify that assumption.
### Issues/PRs references
Introduced in #18846
There is another instance of this attribute being used in[ shell_lock.c](6fb340d654/sys/shell_lock/shell_lock.c (L80)). Since the usage is security related, I omit it from this PR.

17810: drivers/slipdev: implement sleep states r=benpicco a=benpicco
18348: sys/net/gnrc/pktbuf_static: make use of alignas() r=maribu a=maribu
### Contribution description
Since we are now using C11, we can make use of `alignas()` provided by `<stdalign.h>` to make the alignment code easier to read.
### Testing procedure
I didn't expect this to change binaries, but is safes 4 bytes. `elf_diff` shows that the compiler (at least GCC 11.3.0) was not able to detect that `gnrc_pktbuf_static_buf` was just an alias for `_pktbuf_buf`. That makes sense since it would be hard without LTO to rule out external writes to `gnrc_pktbuf_static_buf`, unless one would have added a `const` (to the pointer, not to the data the pointer points to).
The [output of `elf_diff`](https://mari-bu.de/pr_18348_gnrc_pktbuf_static_elf_diff.html) looks otherwise quite unscary.

The macros CONCAT(), MIN(), and MAX() are defined over and over again in
RIOT's code base. This de-duplicates the code by moving the macros to a
common place.
18773: nanocoap_sock: fix handling empty ACKs with separate response r=maribu a=benpicco
Co-authored-by: Benjamin Valentin <benjamin.valentin@ml-pa.com>

If a NON confirmable message is sent with a callback function,
not receiving a response in time would lead to a retransmission.
This is of course an error, as only CON messages are to be retransmitted.
In situations with high packet loss, if all sync packets are lost, conflicting
subnets will be configured.
If the network is static, this can be prevented by always using the highest number
of subnets that has been observed.
This assumes no nodes are physically added / removed from the network.
This eliminates race conditions around unregistering netdevs.
gnrc_netreg_lookup-style functions perform a DEVELHELP check on whether
that lock is held.
