The recent implementation of the listen backlog meant that the logic to
test for readability of such a socket changed, and this commit updates the
logic to work again.
Array to hold waiting connections is in-place if backlog=1, else is a
dynamically allocated array. Incoming connections are processed FIFO
style to maintain fairness.
sizeof() can work in two ways: a) calculate size of already instantiated
structure ("sizeof variable") - in this case we already no layout; b) size
of structure decsription ("sizeof type"). In the latter case, LAYOUT_NATIVE
was assumed, but there should possibility to calculate size for other
layouts too. So, with this patch, there're now 2 forms:
uctypes.sizeof(struct)
uctypes.sizeof(struct_desc, layout)
This value is unused. It was an artifact of early draft design, but
bitfields were optimized to use scalar one-word encoding, to allow
compact encoding of typical multiple bitfields in MCU control
registers.
Since mbedtls 2.7.0 new digest functions were introduced with a "_ret"
suffix to allow the functions to return an error message (eg, if the
underlying hardware acceleration failed). These new functions must be used
instead of the old ones to prevent deprecation warnings, or link errors for
missing functions, depending on the mbedtls configuration.
This removes the need for a separate axtls build stage, and builds all
axtls object files along with other code. This simplifies and cleans up
the build process, automatically builds axtls when needed, and puts the
axtls object files in the correct $(BUILD) location.
The MicroPython axtls configuration file is provided in
extmod/axtls-include/config.h
The underlying socket can handling polling, and any other transparent ioctl
requests. Note that CPython handles the case of polling an ssl object by
polling the file descriptor of the underlying socket file, and that
behaviour is emulated here.
Otherwise they may be called on a socket that no longer exists.
For example, if the GC calls the finaliser on the socket and then reuses
its heap memory, the "callback" entry of the old socket may contain invalid
data. If lwIP then calls the TCP callback the code may try to call the
user callback object which is now invalid. The lwIP callbacks must be
deregistered during the closing of the socket, before all the pcb pointers
are set to NULL.
