Pull request overview
Adds a targeted retry path for Linux wpa_supplicant association attempts that fail with WLAN_STATUS_AUTH_TIMEOUT, improving resilience during stress/commissioning scenarios.
Changes:
- Track association state and a retry budget in
ConnectivityManagerImpl. - On
disconnectedafter an association start, retrySelectNetworkwhenassoc_status_code == WLAN_STATUS_AUTH_TIMEOUT. - Add additional detail logging around
wpa_supplicantstate transitions.

Code Review
The pull request introduces a retry mechanism for WLAN association timeouts, which is a valuable improvement for connection reliability. The changes include adding a constant for maximum retries, logging additional details during state changes and disconnections, and implementing the retry logic. The overall approach is sound, addressing a transient issue observed during stress testing. One area for improvement is ensuring robust error handling if a retry attempt itself fails to initiate, to prevent the system from entering an inconsistent state.

Summary
During stress testing we discovered that the Linux platform code does not recover properly when the initial SelectNetwork dbus call to wpa_supplicant is not successful. We found this to occassionally happen due to
WLAN_STATUS_AUTH_TIMEOUTerrors. When this happens the following messages are being logged bywpa_supplicant:I have implemented a retry mechanism in the Linux platform
ConnectivityManagerwhich triggers specifically in the case of this error (assuming it's a transient problem). We tested this change in our lab and confirmed it improves the commissioning reliability.Testing
