The Key Manager hardware peripheral in its current form needs further
design changes before it can be offered as a production feature.
Until a revised peripheral design is available, withdraw ESP-IDF
support for it on all Key Manager capable targets.
- 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.
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.

Implement the NAN Data Path encrypted datapath per Wi-Fi Aware v4.0
(§7.1.3.5, §9.5.16):
- Responder + initiator sides of the M1-M4 Shared-Key Descriptor
exchange, with MIC compute/verify, PTK derivation, and PMK/PMKID
derivation via PBKDF2-SHA256 over passphrase or pre-shared PMK.
- CSIA / SCIA attribute build + parse, NCS-SK-128 cipher suite.
- Per-NDL security context on ndl_info::security_ctx; per-svc PMK cache.
- ndp_response_indication callback for initiator peer-NDI binding.
- host<->blob ABI migrated from 27 direct esp_nan_* externs to a single
nan_secure_dp_funcs callback struct in esp_private/wifi.h.
- nan_security.c split out of nan_app.c (~340 lines de-duplicated into
shared M1-M4 helpers).
- CONFIG_ESP_WIFI_NAN_ENCRYPTED_DATAPATH gates the secure path so non-
security builds compile out the crypto/handshake code.
- ROM patch (esp32s31): mask ieee80211_encap_esfbuf to match the
c5/c6/c61 pattern for NAN-capable chips.
Hardening: PMK stack copies zeroized on every return, NDP attribute
parsers bounds-checked, CSID range-checked before shifting, NDL slot
reuse only when handshake state is IDLE, get_csia/scia_len aligned with
their builders on empty input.
API surface: NDP security types moved out of esp_wifi_types_generic.h
into esp_private/wifi.h (internal-only). security pointer dropped from
struct ndp_cb_peer_info. Discovery-side wifi_nan_security_type_t and
the NDP Info callbacks removed (subsumed by csid_bitmap and SSI
respectively).
