This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>

We're improving NAN support, but NAN datapath support also means we need to change some other things, e.g. related to rate control. Remove NAN by default again from hwsim since it's the much newer feature.

The NAN notification is for 5745 MHz which corresponds to channel 149
and not 5475 which is not actually a valid channel. This could result in
a NULL pointer dereference in cfg80211_next_nan_dw_notif.

The 'vif' pointer in the Tx information might be NULL, e.g., in
case of injected frames etc. and is not checked in all paths. Fix it.
While at it, also directly use the local 'vif' pointer.

hwsim radios marked destroy_on_close are removed when the Netlink socket
that created them is closed. As the portid is not unique across network
namespaces, closing a socket in one namespace may remove radios in another
if it has the destroy_on_close flag set.
Instead of matching the network namespace, match the netgroup of the radio
to limit radio removal to those that have been created by the closing
Netlink socket. The netgroup of a radio identifies the network namespace
it was created in, and matching on it removes a destroy_on_close radio
even if it has been moved to another namespace.
