## WPA2 Enterprise connections References - merged PRs: * #8529 * #8566 - these occurred with connect/disconnect with WPA-Enterprise * #8736 (comment) The NON-OS SDK 3.0.x has breaking changes to the [`pvPortMalloc`](https://github.com/espressif/ESP8266_NONOS_SDK/blob/bf890b22e57a41d5cda00f9c8191f3f7035a87b4/include/mem.h#L42) function. They added a new `bool` argument for selecting a heap. ```cpp void *pvPortMalloc (size_t sz, const char *, unsigned, bool); ``` To avoid breaking the build, I added a new thin wrapper function `sdk3_pvPortMalloc` to `heap.cpp`. Edited new SDK LIBs to call `pvPortMalloc`'s replacement `sdk3_pvPortMalloc`. They also added `pvPortZallocIram` and `pvPortCallocIram`, which are not a problem to support. Support added to `heap.cpp`. Issues with WPA2 Enterprise in new SDKs: * v3.0.0 and v3.0.1 - have the same memory leak and duplicate free bugs from before * v3.0.2 through v3.0.5 - have the same memory leak; however, _no_ duplicate free crash. * memory leak can be seen by cycling through setup, connect, disconnect, and clear setup - repeatedly. Updated `wpa2_eap_patch.cpp` and binary patch scripts to handle v3.0.0 through v3.0.5. Patched SDKs v3.0.0 through v3.0.5 ## Duplicate Non-32-bit exception handler Issue: At v3.0.0 and above `libmain.a` supplies a built-in exception handler (`load_non_32_wide_handler`) for non-32-bit access. Our non-32-bit access handler (`non32xfer_exception_handler`) overrides it. Solution: Add "weak" attribute to symbol `load_non_32_wide_handler`. Adjust the build to default to the SDK's built-in non-32-bit handler. If there is a need to use our non-32-bit handler, make the selection from the Arduino IDE Tools menu `Non-32-Bit Access: "Byte/Word access to IRAM/PROGMEM (very slow)"`. With SDKs v3.0.0 and above a "non-32-bit exception handler" is always present.

I push the PR again.
I used the 3.0.5, it seems stable.
In Addition, the patch i don't know it needed after 3.0.0
// # WPA2-Enterprise patch which replaces a double-free with nop, see #8082
// # special vPortFree to recover leaked memory
