This patch corrects the SPDX License Identifier style in
header files related to PHY Layer for Ethernet drivers.
For C header files Documentation/process/license-rules.rst
mandates C-like comments (opposed to C source files where
C++ style should be used). This patch also gives an explicit
block comment to the SPDX License Identifier.Changes made by using a script provided by Joe Perches here:

Commit 6570bc79c0df ("net: core: use listified Rx for GRO_NORMAL in
napi_gro_receive()") has applied batched GRO_NORMAL packets processing
to all napi_gro_receive() users, including mac80211-based drivers.However, this change has led to a regression in iwlwifi driver [1][2] as
it is required for NAPI users to call napi_complete_done() or
napi_complete() and the end of every polling iteration, whilst iwlwifi
doesn't use NAPI scheduling at all and just calls napi_gro_flush().
In that particular case, packets which have not been already flushed
from napi->rx_list stall in it until at least next Rx cycle.Fix this by adding a manual flushing of the list to iwlwifi driver right
before napi_gro_flush() call to mimic napi_complete() logics.I prefer to open-code gro_normal_list() rather than exporting it for 2
reasons:
* to prevent from using it and napi_gro_flush() in any new drivers,
as it is the *really* bad way to use NAPI that should be avoided;
* to keep gro_normal_list() static and don't lose any CC optimizations.I also don't add the "Fixes:" tag as the mentioned commit was only a
trigger that only exposed an improper usage of NAPI in this particular
driver.[1] https://lore.kernel.org/netdev/PSXP216MB04388962C411CD0B17A86F47804A0@PSXP216MB0438.KORP216.PROD.OUTLOOK.COM

net: mscc: ocelot: fix potential issues accessing skbs listFix two prtential issues accessing skbs list.
- Break the matching loop when find the matching skb to avoid
consuming more skbs incorrectly. The timestamp ID is only
from 0 to 3 while the FIFO supports 128 timestamps at most.
- Convert to use skb queue instead of the list of skbs to provide

When user-space sets the OVS_UFID_F_OMIT_* flags, and the relevant
flow has no UFID, we can exceed the computed size, as
ovs_nla_put_identifier() will always dump an OVS_FLOW_ATTR_KEY

We need to calculate the skb size correctly otherwise we risk triggering
skb_over_panic[1]. The issue is that data_len is added to the skb in a
nl attribute, but we don't account for its header size (nlattr 4 bytes)
and alignment. We account for it when calculating the total size in
the > PSAMPLE_MAX_PACKET_SIZE comparison correctly, but not when
allocating after that. The fix is simple - use nla_total_size() for
data_len when allocating.To reproduce:
$ tc qdisc add dev eth1 clsact
$ tc filter add dev eth1 egress matchall action sample rate 1 group 1 trunc 129
$ mausezahn eth1 -b bcast -a rand -c 1 -p 129

Note that the sysctl write accessor functions guarantee that:
net->ipv4.sysctl_ip_prot_sock ipv4.ip_local_ports.range[0]
invariant is maintained, and as such the max() in selinux hooks is actually spurious.ie. even though
if (snum < max(inet_prot_sock(sock_net(sk)), low) || snum > high) {
per logic is the same as
if ((snum < inet_prot_sock(sock_net(sk)) && snum < low) || snum > high) {
it is actually functionally equivalent to:
if (snum < low || snum > high) {
which is equivalent to:
if (snum < inet_prot_sock(sock_net(sk)) || snum < low || snum > high) {
even though the first clause is spurious.But we want to hold on to it in case we ever want to change what what
inet_port_requires_bind_service() means (for example by changing
it from a, by default, [0..1024) range to some sort of set).Test: builds, git 'grep inet_prot_sock' finds no other references

ibmvnic: Harden device commands and queriesThis patch series fixes some shortcomings with the current
VNIC device command implementation. The first patch fixes
the initialization of driver completion structures used
for device commands. Additionally, all waits for device
commands are bounded with a timeout in the event that the
device does not respond or becomes inoperable. Finally,
serialize queries to retain the integrity of device return
codes.Changes in v2:
- included header comment for ibmvnic_wait_for_completion
- removed open-coded loop in patch 3/4, suggested by Jakub
- ibmvnic_wait_for_completion accepts timeout value in milliseconds
instead of jiffies
- timeout calculations cleaned up and completed before wait loop
- included missing mutex_destroy calls, suggested by Jakub
- included comment before mutex declaration

"There are several notable changes here:- Single thread migrating itself has been optimized so that it

used for the cgroup and can be used to directly look up live
cgroups through filehandle interface on 64bit ino archs. On 32bit

Pull thread management updates from Christian Brauner:
- A pidfd's fdinfo file currently contains the field "Pid:\t"
where is the pid of the process in the pid namespace of the
procfs instance the fdinfo file for the pidfd was opened in.The fdinfo file has now gained a new "NSpid:\t[\t[...]]"
field which lists the pids of the process in all child pid namespaces
provided the pid namespace of the procfs instance it is looked up
under has an ancestoral relationship with the pid namespace of the
process. If it does not 0 will be shown and no further pid namespaces
will be listed. Tests included. (Christian Kellner)- If the process the pidfd references has already exited, print -1 for
the Pid and NSpid fields in the pidfd's fdinfo file. Tests included.
(me)- Add CLONE_CLEAR_SIGHAND. This lets callers clear all signal handler
that are not SIG_DFL or SIG_IGN at process creation time. This
originated as a feature request from glibc to improve performance and
elimate races in their posix_spawn() implementation. Tests included.
(me)- Add support for choosing a specific pid for a process with clone3().
This is the feature which was part of the thread update for v5.4 but
after a discussion at LPC in Lisbon we decided to delay it for one
more cycle in order to make the interface more generic. This has now
done. It is now possible to choose a specific pid in a whole pid
namespaces (sub)hierarchy instead of just one pid namespace. In order
to choose a specific pid the caller must have CAP_SYS_ADMIN in all
owning user namespaces of the target pid namespaces. Tests included.
(Adrian Reber)- Test improvements and extensions. (Andrei Vagin, me)
