[PATCH 0/3] wifi: Forgive transient errors

In our kiosk system built with ConnMan (currently 1.42) and
wpa_supplicant we have observed frequent "dead-end" errors in customer
installations, especially where WPA3-SAE is used. ConnMan has perfectly
functional WiFi services enter an error state and will not automatically
retry them, so manual intervention of some sort is required (reboot or
manual reselection of WiFi).

We were able to identify various cases where ConnMan's wifi plugin gives
up on services prematurely.

Our hundreds-strong customer base has been running our patched version
of ConnMan since mid-December 2025 and reports of WiFi disconnects have
been much reduced in 2026.

Note that our customers are running ConnMan 1.42 with one additional
patch, which is a revert of 289c7fc5c0e64f14463937cf28eabb347700c161. I
don't understand the reasoning behind this commit, which argues that
ConnMan should not explicitly allow retries, because wpa_supplicant
already has a retry logic. Since ConnMan actively prevents
wpa_supplicant from continuing to retry once the service enters an error
state, this reasoning seems flawed. However, since the change has been
in ConnMan since 2014 and seems to have been generally accepted, I don't
assume a patch suggesting to reinstate a general retry mechanism would
be accepted.

  wifi: Extend auth retry mechanism to WPA3-SAE
  wifi: Limit invalid-key to repeated auth failure
  wifi: Allow retries for more assoc failure cases
