NG: ESP32c3 used in OpenWRT v21 - error in cfg80211 during insmod #313

Closed Philipansari closed 10 months ago

Philipansari commented 10 months ago

I ported the esp-hosted driver (v.1.0.2) to OpenWRT-Linux System (v21) and tried to insert the kernel module. Unfortunately i get the following dmesg traceback errors (see at the end).

Three warnings are displayed and the /net/wireless/core.c source codes are referenced in lines 420 (1.), 432 (2.) and 771 (3.). Here are the corresponding source codes that trigger the warnings:

1. line 420

WARN_ON(ops->auth && (!ops->assoc || !ops->deauth || !ops->disassoc));

2. line 432

WARN_ON(ops->remain_on_channel && !ops->cancel_remain_on_channel);

3. line 771

if (WARN_ON(!(rdev->wiphy.flags & WIPHY_FLAG_SUPPORTS_FW_ROAM) &&
            rdev->ops->update_connect_params))

Here is the source-file of /net/wireless/core.c shown (https://elixir.bootlin.com/linux/v5.4.154/source/net/wireless/core.c)

I don't understand the warnings because looking at the source code at the function int esp_cfg80211_register(struct esp_adapter *adapter) at https://github.com/espressif/esp-hosted/blob/release/ng-v1.0.2/esp_hosted_ng/host/esp_cfg80211.c

  1. the cfg80211_ops auth, assoc, deauth and disassoc are defined.
  2. ops remain_on_channel is not defined
  3. either the flag WIPHY_FLAG_SUPPORTS_FW_ROAM nor the ops update_connect_params is defined.

Maybe im on the wrong track here?

I've already tried to find a similar problem in other issues, but I haven't found anything like it.

Here is the log of dmesg regarding the kernel module

@Philipansari any reason for not using latest driver? Could you please rebase your changes on latest driver and check once. Also please share the changes if you have made any in the wifi driver.

Philipansari commented 10 months ago

You mean latest esp-hosted driver? thought i do so, or should i checkout to master branch? Yesterday there were some compilation errors so i preferred to use the release version.

I just tried to cross-compile the kernel module.

There were some compilation errors for my specific kernel version (5.4.154)

However on the esp32 side there is a problem during the compilation of network_adapter:

Running the latest driver on the linux-side and the release version v1.0.2 on the esp-side is resulting in basically the same errors, see dmesg log:

I've made no changes to the driver itself expect adjusting the IOs to the ones i need (via the pre-processor macros)

Philipansari commented 10 months ago

It seems there is a mismatch between the used kernel version during compilation time (v5.4.154) and execution time on the target. (backports-5.10.68). There is a different offset in the struct cfg80211_ops struct containing the several functions. Considering the different offsets of the defined functions the warning messages started to make sense:

v5.4.154 offset in bytes v5.10.68
scan 8 auth
connect 8 update_connect_params
disconnect 8 join_ibss
add_key 0
del_key 0
set_default_key 0
mgmt_tx 16 set_power_mgmt
auth 8 assoc
deauth 8 disassoc
disassoc 8 connect
assoc 8 deauth
suspend 0
resume 0
set_wakeup 0

Hacking the functions in the right place resolves the warning. So it probably has nothing to do with the esp-hosted repo, sorry for that.
