Wireless access point daemon, patched with ubus support
bbb0d3a40e
The wpa_auth_callbacks for mesh was missing a for_each_sta
implementation. This is an issue with pmksa cache, as when a cache entry
expires the for_each_sta callback is called in order to clear the pmksa
reference for all sta that was using this entry. Not having a
for_each_sta callback will prevent this cleanup to happen then a sta
could still use this pmksa entry even after it has been freed.
This used after free was not a problem up until recently where
dpp_pkhash is now stored in pmksa entry and retreived later on causing
crash with below backtrace:

Adding a for_each_sta callbacks fixes that.
