iwlwifi: mvm: write queue_sync_state only for sync

2020-12-02T07:51:52+00:00

[ Upstream commit 97cc16943f23078535fdbce4f6391b948b4ccc08 ] We use mvm->queue_sync_state to wait for synchronous queue sync messages, but if an async one happens inbetween we shouldn't clear mvm->queue_sync_state after sending the async one, that can run concurrently (at least from the CPU POV) with another synchronous queue sync.

iwlwifi: mvm: properly cancel a session protection for P2P

2020-12-02T07:51:52+00:00

[ Upstream commit 1cf260e3a75b87726ec609ad1b6b88f515749786 ] We need to feed the configuration id to remove session protection properly. Remember the conf_id when we add the session protection so that we can give it back when we want to remove the session protection. While at it, slightly improve the kernel doc for the conf_id of the notification.

iwlwifi: mvm: use the HOT_SPOT_CMD to cancel an AUX ROC

2020-12-02T07:51:52+00:00

[ Upstream commit fb8d1b6e97980057b7ebed444b8950e57f268a67 ] The ROC that runs on the AUX ROC (meaning an ROC on the STA vif), was added with the HOT_SPOT_CMD firmware command and must be cancelled with that same command.

iwlwifi: dbg: run init_cfg function once per driver load

[ Upstream commit 42f8a2735cc218b6b372134684d4cd3c1423f123 ] Every time we call init_cfg driver appends the enabled triggers to the active triggers while this should be done only once per driver load.

mm, treewide: rename kzfree() to kfree_sensitive()

2020-08-07T18:33:22+00:00

As said by Linus: A symmetric naming is only helpful if it implies symmetries in use. Otherwise it's actively misleading. In "kzalloc()", the z is meaningful and an important part of what the caller wants. In "kzfree()", the z is actively detrimental, because maybe in the future we really _might_ want to use that "memfill(0xdeadbeef)" or something. The "zero" part of the interface isn't even _relevant_. The main reason that kzfree() exists is to clear sensitive information that should not be leaked to other future users of the same memory objects. Rename kzfree() to kfree_sensitive() to follow the example of the recently added kvfree_sensitive() and make the intention of the API more explicit. In addition, memzero_explicit() is used to clear the memory to make sure that it won't get optimized away by the compiler. The renaming is done by using the command sequence: git grep -w --name-only kzfree |\ xargs sed -i 's/kzfree/kfree_sensitive/' followed by some editing of the kfree_sensitive() kerneldoc and adding a kzfree backward compatibility macro in slab.h.
