wireless: Remove redundant 'flush_workqueue()' calls

2024-03-26T22:21:50+00:00

[ Upstream commit ff1cc2fa3055ee4c83839f38b74b4ee370a2291c ]

'destroy_workqueue()' already drains the queue before destroying it, so
there is no need to flush it explicitly.

Remove the redundant 'flush_workqueue()' calls.

This was generated with coccinelle:

@@
expression E;
@@
- 	flush_workqueue(E);
	destroy_workqueue(E);

qtnfmac: Fix possible buffer overflow in qtnf_event_handle_external_auth

2021-05-19T08:12:58+00:00

[ Upstream commit 130f634da1af649205f4a3dd86cbe5c126b57914 ]

Function qtnf_event_handle_external_auth calls memcpy without
checking the length.
A user could control that length and trigger a buffer overflow.
Fix by checking the length is within the maximum allowed size.

[ Upstream commit 31e07aa33fa7cdc93fa91c3f78f031e8d38862c2 ]

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

Rejecting non-native endian BTF overlapped with the addition
of support for it.

The rest were more simple overlapping changes, except the
renesas ravb binding update, which had to follow a file
move as well as a YAML conversion.

qtnfmac: fix resource leaks on unsupported iftype error return path

2020-09-29T08:23:47+00:00

Currently if an unsupported iftype is detected the error return path
does not free the cmd_skb leading to a resource leak. Fix this by
free'ing cmd_skb.

net: core: introduce struct netdev_nested_priv for nested interface infrastructure

2020-09-28T22:00:15+00:00

Functions related to nested interface infrastructure such as
netdev_walk_all_{ upper | lower }_dev() pass both private functions
and "data" pointer to handle their own things.
At this point, the data pointer type is void *.
In order to make it easier to expand common variables and functions,
this new netdev_nested_priv structure is added.

In the following patch, a new member variable will be added into this
struct to fix the lockdep issue.
