Subject: [PATCH] wifi: mac80211: Add link iteration macro for link data with
|
|
rcu_dereference
|
|
|
|
Currently, the existing macro for_each_link_data() uses sdata_dereference()
|
|
which requires the wiphy lock. This lock cannot be used in atomic or RCU
|
|
read-side contexts, such as in the RX path.
|
|
|
|
Introduce a new macro, for_each_link_data_rcu(), that iterates over link of
|
|
sdata using rcu_dereference(), making it safe to use in RCU contexts. This
|
|
allows callers to access link data without requiring the wiphy lock.
|
|
|
|
The macro takes into account the vif.valid_links bitmap and ensures only
|
|
valid links are accessed safely. Callers are responsible for ensuring that
|
|
rcu_read_lock() is held when using this macro.
