Jared Hancock	f29bd5a65e	extmod/modlwip: Fix incorrect peer address for IPv6. ... For IPv6 connections, the peer address was previously defined as only the first four bytes of the IP address. For IPv6 addresses, this resulted in an incorrect IPv4 address. For instance, receiving a packet via `::recvfrom` from `'fe80::87:e7ff:fe48:629a'` is returned as having a peer address of `'254.128.0.0'` Signed-off-by: Jared Hancock <jared.hancock@centeredsolutions.com>	2025-01-29 10:49:34 +11:00

Damien George	50637ff239	extmod/vfs_rom: Add VfsRom filesystem object. ... This commit defines a new ROMFS filesystem for storing read-only files that can be memory mapped, and a new VfsRom driver. Files opened from this filesystem support the buffer protocol. This allows naturally getting the memory-mapped address of the file using: - memoryview(file) - uctypes.addressof(file) Furthermore, if these files are .mpy files then their content can be referenced in-place when importing. Such imports take up a lot less RAM than importing from a normal filesystem. This is essentially dynamically frozen .mpy files, building on the revamped v6 .mpy file format.

Corran Webster	e70048cf59	extmod/modframebuf: Fix 0 radius bug in FrameBuffer.ellipse. ... This fixes a bug in FrameBuffer.ellipse where it goes into an infinite loop if both radii are 0. This fixes the bug with a simple pre-check to see if both radii are 0, and in that case sets a single pixel at the center. This is consistent with the behaviour of the method when called with just one of the radii set to 0, where it will draw a horizontal or vertical line of 1 pixel width. The pixel is set with setpixel_checked so it should handle out-of-bounds drawing correctly. This fix also includes three new tests: one for the default behaviour, one for drawing out-of-bounds, and one for when the sector mask is 0. Fixes issue #16053.

Angus Gratton	181800eebd	extmod/network_cyw43: Allow configuring active AP interface. ... Configuring the AP for cyw43 writes to some buffers that are only sent to the modem when the interface is brought up. This means you can't configure the AP after calling active(True), the new settings seem to be accepted but the radio doesn't change. This is different to the WLAN behaviour on other ports. The esp8266 port requires calling active(True) on the AP before configuring, even. Fix this by bouncing the AP interface after a config change, if it's active. Configuring with active(False) still works the same as before. Adds a static variable to track interface active state, rather than relying on the LWIP interface state. This is because the interface state is updated by a driver callback and there's a race: if code calls active(True) and then config(a=b) then the driver doesn't know it's active yet and the changes aren't correctly applied. It is possible this pattern will cause the AP to come up briefly with the default "PICOabcd" SSID before being reconfigured, however (due to the aforementioned race condition) it seems like this may not happen at all before the new config is applied.

Damien George	5dc9eda195	extmod/vfs_blockdev: Support bool return from Python read/write blocks. ... Commit f4ab9d9247 inadvertently broke some Python block devices, for example esp32 and stm32 SDCard classes. Those classes return a bool from their `readblocks` and `writeblocks` methods instead of an integer errno code. With that change, both `False` and `True` return values are now be interpreted as non-zero and hence the block device call fails. The fix in this commit is to allow a bool and explicitly convert `True` to 0 and `False` to `-MP_EIO`. Signed-off-by: Damien George <damien@micropython.org>	2024-11-13 14:21:29 +11:00
Daniël van de Giessen	77406b4240	extmod/network_ppp: Allow stream=None to suspend PPP. ... This allows the stream to be set to `None`, which essentially stops all PPP communication without disconnecting the session. This allows replacing the stream on-the-fly to suspend it, for example to send AT commands to a modem without completely disconnecting and re-establishing the PPP connection: uart = ppp.config('stream') ppp.config(stream=None) uart.write(b'+++') # do some AT commands uart.write(b'ATO\r\n') ppp.config(stream=uart) Any attempted communication by PPP while the stream is not connected will register as simple packet loss to the LwIP stack because we return 0 for any write calls, and protocols like TCP will then automatically handle retrying.

iabdalkader	68f1c20145	extmod/modtls_mbedtls: Support alternate sign callbacks in Python. ... This commit enables the implementation of alternative mbedTLS cryptography functions, such as ECDSA sign and verify, in pure Python. Alternative functions are implemented in Python callbacks, that get invoked from wrapper functions when needed. The callback can return None to fall back to the default mbedTLS function. A common use case for this feature is with secure elements that have drivers implemented in Python. Currently, only the ECDSA alternate sign function wrapper is implemented.

Corran Webster	d1574de3b6	extmod/modframebuf: Fix FrameBuffer size check for stride corner-cases. ... This is a fix for issue #15944, and handles corner cases in the FrameBuffer code when using stride values where the last line's stride may extend past the end of the underlying buffer. This commit includes extra tests for these corner cases. For example a GS8 format FrameBuffer with a width of 8, height of 2 and stride of 10 should be able to fit into a buffer of size 18 (10 bytes for the first horizontal line, and 8 bytes for the second -- the full 10 bytes are not needed). Similarly a 1 by 9 FrameBuffer in MONO_VLSB format with a stride of 10 should be able to fit into a buffer of length 11 (10 bytes for the first 8 lines, and then one byte for the 9th line. Being able to do this is particularly important when cropping the corner of an existing FrameBuffer, either to copy a sprite or to clip drawing.

It has been tested on stm32. A board needs to enable `MICROPY_PY_NETWORK_PPP_LWIP` and then it can use it as follows: import network ppp = network.PPP(uart) ppp.connect() while not ppp.isconnected(): pass # use `socket` module as usual, etc ppp.disconnect() Usually the application must first configure the cellular/etc UART link to get it connected and in to PPP mode first (eg ATD*99#), before handing over control to `network.PPP`.

Angus Gratton	86f2c285eb	py: Add new cstack API for stack checking, with limit margin macro. ... Currently the stack limit margin is hard-coded in each port's call to `mp_stack_set_limit()`, but on threaded ports it's fiddlier and can lead to bugs (such as incorrect thread stack margin on esp32). This commit provides a new API to initialise the C Stack in one function call, with a config macro to set the margin. Where possible the new call is inlined to reduce code size in thread-free ports. Intended replacement for `MP_TASK_STACK_LIMIT_MARGIN` on esp32. The previous `stackctrl.h` API is still present and unmodified apart from a deprecation comment.

Peter Züger	4d6d84983f	extmod/modtls_mbedtls: Fix DER parsing and calculation of key/cert len. ... `mbedtls_pk_parse_key()` expects `key_len` to include the NULL terminator for PEM data but not for DER encoded data. This also applies to `mbedtls_x509_crt_parse()` and `cert_len`. Since all PEM data contains "-----BEGIN" this is used to check if the data is PEM (as per mbedtls code). This can be done for both v2 and v3 of mbedtls since the fundamental behaviour/expectation did not change. What changed is that in v3 the PKCS#8 DER parser now checks that the passed key buffer is fully utilized and no bytes are remaining (all other DER formats still do not check this).

Damien George	69c25ea865	shared/runtime/pyexec: Make a raised SystemExit always do a forced exit. ... The current situation with SystemExit and soft reset is the following: - `sys.exit()` follows CPython and just raises `SystemExit`. - On the unix port, raising `SystemExit` quits the application/MicroPython, whether at the REPL or in code (this follows CPython behaviour). - On bare-metal ports, raising `SystemExit` at the REPL does nothing, raising it in code will stop the code and drop into the REPL. - `machine.soft_reset()` raises `SystemExit` but with a special flag set, and bare-metal targets check this flag when it propagates to the top-level and do a soft reset when they receive it. The original idea here was that a bare-metal target can't "quit" like the unix port can, and so dropping to the REPL was considered the same as "quit". But this bare-metal behaviour is arguably inconsistent with unix, and "quit" should mean terminate everything, including REPL access. This commit changes the behaviour to the following, which is more consistent: - Raising `SystemExit` on a bare-metal port will do a soft reset (unless the exception is caught by the application). - `machine.soft_reset()` is now equivalent to `sys.exit()`. - unix port behaviour remains unchanged. Tested running the test suite on an stm32 board and everything still passes, in particular tests that skip by raising `SystemExit` still correctly skip.
