NimBLE memory leak?

Postby davdav » Tue Feb 16, 2021 3:55 pm

Hi everybody,

I'm trying to port our application which used Bluedroid to nimBLE. I'm working with esp-idf-v4.2.

In my opinion there is a memory leak when nimble is init and deinit if GAP advertizing is used.

I have written a simple code to test it (derived from "bleprph" example). Please find attached the code and my sdkconfig (renamed to .txt to be able to attach).

The test is simple. At start-up nimble is init and esp32 start advertizing.
After 30 seconds advertizing is stopped and nimBLE deinit.
After 30 seconds nimble is init and start advertizing and so on...
Program is working as expected and I can monitor using a "beacon scanner" APP that advertiziing start/stop correctly.

Everytime I init and deinit nimBLE, I print the available heap using function "esp_get_free_heap_size" and as you can see it decreases of 48 bytes each time it is init/deinit.

Code: Select all

I think to have done everything correct.

Hi,


Can you create an issue in our GitHub to report that?

@davdav

Thank you for reporting the issue and for providing a simplistic code to recreate the same. Yes, this looks like a problem.
Just to give you some background, the NimBLE upstream does not yet have the stop/deinit support integrated. We have added this functionality to our port (esp-nimble). When it was first added, it was verified that there was no memory leak. This looks like a regression:

The NimBLE upstream software release after that seem to have added a data structure in the stop procedure. We, in our port, need to remove/delete it in the deinit procedure as we support init/deinit multiple times. We will share a patch here for you to verify, when it is done. Thanks!

Hi @ESP_Hrishi,

I remain at your disposal. consider that in my "real application" the leak seems more than 48 byte (about 500bytes) but I didn't shared the code because it is quite complex (and maybe there are programming issues on my side) so I preferred to give a small and repeatable code.

@ESP_Minatel: should I still open issue in github? Or is it already opened in your internal system?

Thanks

@davdav

You don't need to file an issue. It is now tracked internally.

Quick fix: Can you please add the following line (in green) below ble_npl_callout_stop in the file esp-idf/components/bt/host/nimble/nimble/nimble/host/src/ble_hs_stop.c:

ble_npl_callout_stop(&ble_hs_stop_terminate_tmo);
ble_npl_callout_deinit(&ble_hs_stop_terminate_tmo);

With this I could see the free heap remaining constant (with your example) for the subsequent init/deinit cycles. Please try it out and let me know if this helps. Once verified, we can review and add it to the mainline.

P.S. This is a single line change and hence I thought to give it directly instead of creating a patch. Thanks!

Hello @ESP_Hrishi,

I'm sorry but I don't find "ble_npl_callout_stop" in ble_hs_stop.c file.

As mentioned in my original post I'm using esp-idf-v4.2 where esp-nimble has commit 95bd864 (nimble-v1.2.0-idf branch).
Should I update the entire submodule nimble? I have verified that "ble_npl_callout_stop" is present in "nimble-v1.3.0-idf" branch.

Thanks!

@davdav

Sorry for missing this in the first place. I just tried it with latest `release/v4.2` branch (ESP-IDF Github with NimBLE submodule head ba72e37ac40c13b66ad49c3178c0dbc9588add61 from `nimble-1.2.0-idf` branch ) and I am not able to see any issue with your code.

Hello @ESP_Hrishi,

I'm on TAG" v4.2" (https://github.com/espressif/esp-idf/tree/v4.2/) not branch "release/v4.2":

I guess the correct way is to use the TAG which is associated to stable and "verified" version.

Anyway I will try to update submodule "nimble" to the commit you specifed.


Thanks!

Hello @ESP_Hrishi,

What should I need to add/edit in "esp-nimble head: 95bd8644abf4a410dd3fb914468d3a23ac9bbec2 nimble-1.2.0-idf branch" to let it work?

Or are you saying that my test example with "ESP-IDF Github head: c40f2590bf759ff60ef122afa79b4ec04e7633d2 esp-nimble head: 95bd8644abf4a410dd3fb914468d3a23ac9bbec2 nimble-1.2.0-idf branch" is working as expected (no leak)?

In your first reply you confirmed there was an issue, so at this point I do not understand if my test was wrong or I need to edit/patch some code of "esp-nimble"

Thanks!
