When we exceed the limit of BSS entries, this function will free the new entry, however, at this time, it is the last door to access the inputed ies, so these ies will be unreferenced objects and cause memory leak. Therefore we should free its ies before deallocating the new entry, beside of dropping it from hidden_list. Signed-off-by: Nguyen Dinh Phi <redacted>[...]quoted
Did this change get lost somewhere?Johannes applied it to the macc80211 tree: https://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211.git/commit/?id=f9a5c358c8d26fed0cc45f2afc64633d4ba21dff Ah, and it's already in Linus' tree as well.
Ah, thanks, I had missed that it just landed there. greg k-h
