Validate MTU from DHCP option 26 against RFC 2132 minimum (68 bytes)
before applying to netif->mtu, preventing rogue DHCP servers from
setting MTU to 0 or other dangerously low values that cause integer
wraparound in IPv4 fragmentation.
httpd_req_get_hdr_value_str() detected truncation with `val_size < full_size`, where full_size is the strlcpy() return value. strlcpy() returns strlen() of the source (the terminating null is not counted), so truncation actually occurs when strlen(src) >= val_size. At strlen(src) == val_size the value is copied as val_size - 1 chars + NUL (i.e. truncated) yet ESP_OK was returned, so the caller never learned the value was cut.
Use `val_size <= full_size` and correct the misleading comment about strlcpy()'s return value.
Same truncation-reporting class fixed for httpd_cookie_key_value in PR #16202; httpd_req_get_hdr_value_str was missed. No memory-safety impact: strlcpy() null-terminates if val_size > 0.
Handle absent IROM/DROM alignment gap in SPIRAM-XIP memprot tests
Closes IDFCI-5004, IDFCI-11739, and IDFCI-11738

- Add nira attr and verification for pasn auth frames
- Refine key clearing and pairing complete logic for pasn verify
- Add NIRA own-service resolution, cached NIK checks, and dynamic
pairing IE construction for bootstrap vs verify paths.
- Replace NAN bootstrap events by private callbacks
Add esp_netif_add_static_neighbor() and esp_netif_remove_static_neighbor(),
gated by CONFIG_LWIP_ND6_SUPPORT_STATIC_ENTRIES. These API's let callers
install/remove permanent IPv6->MAC mappings that bypass Neighbor Discovery
(no NS/NA). The calls run in the TCP/IP context and wrap the underlying lwIP
nd6_add_static_neighbor()/nd6_remove_static_neighbor() functions.
When the NimBLE stack called this callback for a GATT Write Request, the
uninitialized stack value was interpreted as a non-zero GATT error code,
causing the stack to send BLE_ATT_ERR_UNLIKELY (0x0E) back to the client.
The signing step (espsecure sign-data) derives the signature block type
from the key file itself, so selecting e.g. the RSA app signing scheme
with an ECDSA signing key produced a successfully built image that only
failed signature verification at boot.
Check the key at configure time and fail with a clear error when:
- the key family (RSA vs ECDSA) does not match the selected app signing
scheme
- the ECDSA curve does not match the selected ECDSA key size for the
ECDSA (V1/V2) schemes
- the key cannot be parsed as an unencrypted PEM private key
esp_crypto_shared_gdma_done() polled the AXI RX raw interrupt status
(in_done) but never cleared it, so after the first transfer the set bit
made every subsequent call return immediately without waiting.
Use dual-path macros: C keeps fragment-style designated initializers;
C++ uses GNU statement expressions (ESP_LOG_CONFIG_INIT pattern).
Add compile-only C++ regression tests for LP UART/I2C and ULP RISC-V I2C.
