TCP stack is not attaching skb to TIME_WAIT sockets yet,
but we would like to allow this in the future.
Add sk_listener_or_tw() helper to detect the three states
that FQ needs to take care.
Like NEW_SYN_RECV, TIME_WAIT are not full sockets and
do not contain sk->sk_pacing_status, sk->sk_pacing_rate.

This patch adds missing percpu_ref_exit when releasing percpu refs.
When releasing percpu refs, percpu_ref_exit should be called.

Address byte-order miss-matches flagged by Sparse.
In tg3_load_firmware_cpu() and tg3_get_device_address()
this is done using appropriate types to store big endian values.
In the cases of tg3_test_nvram(), where buf is an array which
contains values of several different types, cast to __le32
before converting values to host byte order.

As Andrew pointed out, it will make sense that the PTP core
checked timespec64 struct's tv_sec and tv_nsec range before calling
ptp->info->settime64().
As the man manual of clock_settime() said, if tp.tv_sec is negative or
tp.tv_nsec is outside the range [0..999,999,999], it should return EINVAL,
which include dynamic clocks which handles PTP clock, and the condition is
consistent with timespec64_valid(). As Thomas suggested, timespec64_valid()
only check the timespec is valid, but not ensure that the time is
in a valid range, so check it ahead using timespec64_valid_strict()
in pc_clock_settime() and return -EINVAL if not valid.
There are some drivers that use tp->tv_sec and tp->tv_nsec directly to
write registers without validity checks and assume that the higher layer
has checked it, which is dangerous and will benefit from this, such as
hclge_ptp_settime(), igb_ptp_settime_i210(), _rcar_gen4_ptp_settime(),
and some drivers can remove the checks of itself.

As described in commit b07996c7abac ("sched_ext: Don't hold
scx_tasks_lock for too long"), we're doing a cond_resched() every 32
calls to scx_task_iter_next() to avoid RCU and other stalls. That commit
also added a cpu_relax() to the codepath where we drop and reacquire the
lock, but as Waiman described in [0], cpu_relax() should only be
necessary in busy loops to avoid pounding on a cacheline (or to allow a
hypertwin to more fully utilize a core).
Let's remove the unnecessary cpu_relax().

A ring buffer which has its buffered mapped at boot up to fixed memory
should not be freed. Other buffers can be. The ref counting setup was
wrong for both. It made the not mapped buffers ref count have zero, and the
boot mapped buffer a ref count of 1. But an normally allocated buffer
should be 1, where it can be removed.
Keep the ref count of a normal boot buffer with its setup ref count (do
not decrement it), and increment the fixed memory boot mapped buffer's ref
count.

Let's bring xdp_buff_xsk back to occupying 2 cachelines by removing
xskb_list_node - for the purpose of gathering the xskb frags
free_list_node can be used, head of the list (xsk_buff_pool::xskb_list)
stays as-is, just reuse the node ptr.
It is safe to do as a single xdp_buff_xsk can never reside in two
pool's lists simultaneously.

The id_temp local variable in am65_cpsw_nuss_probe() is
used to hold a 64-bit big-endian value as it is assigned using
cpu_to_be64().
It is read using memcpy(), where it is written as an identifier into a
byte-array. So this can also be treated as big endian.
As it's type is currently host byte order (u64), sparse flags
an endian mismatch when compiling for little-endian systems:
.../am65-cpsw-nuss.c:3454:17: warning: incorrect type in assignment (different base types)

Due to problem reports in the past SG and TSO/TSO6 are disabled per
default. It's not fully clear which chip versions are affected, so we
may impact also users of unaffected chip versions, unless they know
how to use ethtool for enabling SG/TSO/TSO6.
Vendor drivers r8168/r8125 enable SG/TSO/TSO6 for selected chip
versions per default, I'd interpret this as confirmation that these
chip versions are unaffected. So let's do the same here.

sysfs warns if we're removing a symlink from a directory that's no
longer in sysfs; this is triggered by fstests generic/730, which
simulates hot removal of a block device.
This patch is however not a correct fix, since checking
kobj->state_in_sysfs on a kobj owned by another subsystem is racy.
A better fix would be to add the appropriate check to
sysfs_remove_link() - and sysfs_create_link() as well.
But kobject_add_internal()/kobject_del() do not as of today have locking
that would support that.
Note that the block/holder.c code appears to be subject to this race as
well.

When creating a new stripe, we may reuse an existing stripe that has
some empty and some nonempty blocks.
Generally, the existing stripe won't change underneath us - except for
block sector counts, which we copy to the new key in
ec_stripe_key_update.
But the device removal path can now invalidate stripe pointers to a
device, and that can race with stripe reuse.

ethtool: Add support for writing firmware
In the CMIS specification for pluggable modules, LPL (Local Payload) and
EPL (Extended Payload) are two types of data payloads used for managing
various functions and features of the module.
EPL payloads are used for more complex and extensive management functions
that require a larger amount of data, so writing firmware blocks using EPL
is much more efficient.
Currently, only LPL payload is supported for writing firmware blocks to

Add support for writing firmware block using EPL payload, both to support

Running the flashing command on the same sample module using EPL vs. LPL
showed an improvement of 84%.

Pull driver core fixes from Greg KH:
"Here is a single driver core fix, and a .mailmap update.
The fix is for the rust driver core bindings, turned out that the
from_raw binding wasn't a good idea (don't want to pass a pointer to a
reference counted object without actually incrementing the pointer.)
So this change fixes it up as the from_raw binding came in in -rc1.
The other change is a .mailmap update.
Both have been in linux-next for a while with no reported issues"
* tag 'driver-core-6.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core:
mailmap: update mail for Fiona Behrens
rust: device: change the from_raw() function

net: vxlan: add skb drop reasons support
In this series, we add skb drop reasons support to VXLAN, and following
new skb drop reasons are introduced:
SKB_DROP_REASON_VXLAN_INVALID_HDR
SKB_DROP_REASON_VXLAN_VNI_NOT_FOUND
SKB_DROP_REASON_VXLAN_ENTRY_EXISTS
SKB_DROP_REASON_VXLAN_NO_REMOTE
SKB_DROP_REASON_MAC_INVALID_SOURCE
SKB_DROP_REASON_IP_TUNNEL_ECN
SKB_DROP_REASON_TUNNEL_TXINFO
SKB_DROP_REASON_LOCAL_MAC
We add some helper functions in this series, who will capture the drop
reasons from pskb_may_pull_reason and return them:
pskb_network_may_pull_reason()
pskb_inet_may_pull_reason()
And we also make the following functions return skb drop reasons:
skb_vlan_inet_prepare()
vxlan_remcsum()
vxlan_snoop()
vxlan_set_mac()
Changes since v6:
- fix some typos in the document for SKB_DROP_REASON_TUNNEL_TXINFO
Changes since v5:
- fix some typos in the document for SKB_DROP_REASON_TUNNEL_TXINFO
Changes since v4:
- make skb_vlan_inet_prepare() return drop reasons, instead of introduce
a wrapper for it in the 3rd patch.
- modify the document for SKB_DROP_REASON_LOCAL_MAC and
SKB_DROP_REASON_TUNNEL_TXINFO.
Changes since v3:
- rename SKB_DROP_REASON_VXLAN_INVALID_SMAC to
SKB_DROP_REASON_MAC_INVALID_SOURCE in the 6th patch
Changes since v2:
- move all the drop reasons of VXLAN to the "core", instead of introducing
the VXLAN drop reason subsystem
- add the 6th patch, which capture the drop reasons from vxlan_snoop()
- move the commits for vxlan_remcsum() and vxlan_set_mac() after
vxlan_rcv() to update the call of them accordingly
- fix some format problems
Changes since v1:
- document all the drop reasons that we introduce
- rename the drop reasons to make them more descriptive, as Ido advised
- remove the 2nd patch, which introduce the SKB_DR_RESET
- add the 4th patch, which adds skb_vlan_inet_prepare_reason() helper
- introduce the 6th patch, which make vxlan_set_mac return drop reasons
- introduce the 10th patch, which uses VXLAN_DROP_NO_REMOTE as the drop
reasons, as Ido advised

Replace kfree_skb/dev_kfree_skb with kfree_skb_reason in vxlan_xmit_one.
No drop reasons are introduced in this commit.
The only concern of mine is replacing dev_kfree_skb with
kfree_skb_reason. The dev_kfree_skb is equal to consume_skb, and I'm not
sure if we can change it to kfree_skb here. In my option, the skb is
"dropped" here, isn't it?

Change the return type of vxlan_set_mac() from bool to enum
skb_drop_reason. In this commit, the drop reason
"SKB_DROP_REASON_LOCAL_MAC" is introduced for the case that the source
mac of the packet is a local mac.

Make vxlan_remcsum() support skb drop reasons by changing the return
value type of it from bool to enum skb_drop_reason.
The only drop reason in vxlan_remcsum() comes from pskb_may_pull_reason(),
so we just return it.
