- fixed IntegerDividedByZero during Qos negotiation.
Closes https://github.com/espressif/esp-idf/issues/18951
- ignored the check for bandwidth and retransmission effort when Host
accepts the SCO connection request.
fix(bt): Fixed memory-safety and DoS defects in BR/EDR controller on ESP32-S31
Closes BTQABR2023-853 and BTQABR2023-852
See merge request espressif/esp-idf!51299
- remmediate deep-review memory-saftey and DoS defects
- fix duplicated report of HCI mode change event
- fix conflicts in handling sniff subrate request when ACL link enters active mode
Fixed bug when BR/EDR ACL-U dynamic Tx buffer is enabled
Fixed infinite loop during connection set-up
Optimized the scheduling of SCO/eSCO and sniff events
In the Bluetooth connections with some smartphones, communication can possibly be blocked
during packet type negotation, when ESP32-S31 attempts to finalize the ACL-U transmission
and waits for the last Tx ACL-U packet to be transmitted, but peer device rejects the
packet with FLOW=STOP in its packet, thus causing a deadlock.

fix(mmap): fixed mmap read data wrong when flash being erased/written and cache not disabled
Closes IDFGH-14084
See merge request espressif/esp-idf!29804
- Fix connection failure when using RPA with whitelist filtering
- Fix disconnect with reason 0x08 during full scan
- Fix peer RPA resolution failure when advertising with a local identity address
Before:
The cache won't be disabled when XIP on psram. But during flash
erasing/programming, read data will be courrupt.
When XIP in psram is enabled, the image is not mapped to the cache so
usually there will be no flash access. The only way to read from flash
is via the driver or use mmap. The driver has protection during erasing,
while th mmap region not.
Now:
Mmap APIs provide a flag to make mmap->unmap region mutually exclusive
to flash erase/programming when XIP from psram. SPI Flash write APIs
will benefit from this. When the flag is used, no concurrent access to
mapped region will happen while writing; otherwise the cache will be
disable to avoid data corruption.
Most ESP-IDF APIs calls mmap with this flag. As for users calling
mmap-like APIs directly, they can choose whether to enable this by a
flag.
