net: dev: add skb drop reasons to net/core/dev.c

In the commit c504e5c2 ("net: skb: introduce kfree_skb_reason()"),
we added the support of reporting the reasons of skb drops to kfree_skb
tracepoint. And in this series patches, reasons for skb drops are added
to the link layer, which means that 'net/core/dev.c' is our target.

Following functions are processed:

sch_handle_egress()
__dev_xmit_skb()
enqueue_to_backlog()
do_xdp_generic()
sch_handle_ingress()
__netif_receive_skb_core()

and following new drop reasons are added (what they mean can be see in
the document of them):

SKB_DROP_REASON_QDISC_EGRESS
SKB_DROP_REASON_QDISC_DROP
SKB_DROP_REASON_CPU_BACKLOG
SKB_DROP_REASON_XDP
SKB_DROP_REASON_QDISC_INGRESS
SKB_DROP_REASON_PTYPE_ABSENT

In order to add skb drop reasons to kfree_skb_list(), the function
kfree_skb_list_reason() is introduced in the 2th patch, which will be
used in __dev_xmit_skb() in the 3th patch.

100GbE Intel Wired LAN Driver Updates 2022-03-03

Jacob Keller says:

This series refactors the ice networking driver VF storage from a simple
static array to a hash table. It also introduces krefs and proper locking
and protection to prevent common use-after-free and concurrency issues.

There are two motivations for this work. First is to make the ice driver
more resilient by preventing a whole class of use-after-free bugs that can
occur around concurrent access to VF structures while removing VFs.

The second is to prepare the ice driver for future virtualization work to
support Scalable IOV, an alternative VF implementation compared to Single
Root IOV. The new VF implementation will allow for more dynamic VF creation
and removal, necessitating a more robust implementation for VF storage that
can't rely on the existing mechanisms to prevent concurrent access
violations.

The first few patches are cleanup and preparatory work needed to make the
conversion to the hash table safe. Following this preparatory work is a
patch to migrate the VF structures and variables to a new sub-structure for
code clarity. Next introduce new interface functions to abstract the VF
storage. Finally, the driver is actually converted to the hash table and
kref implementation.

Automated tools complain that felix_check_xtr_pkt() has logic to drain

This is not likely to happen (/possible if hardware works correctly),
but it isn't a fatal condition either. The PTP packet will be dequeued
from the CPU queue when the next PTP packet arrives. So initialize "err"
to 0 for the case where nothing was dequeued during this iteration.

The ice driver stores VF structures in a simple array which is allocated
once at the time of VF creation. The VF structures are then accessed
from the array by their VF ID. The ID must be between 0 and the number
of allocated VFs.

Multiple threads can access this table:

 * .ndo operations such as .ndo_get_vf_cfg or .ndo_set_vf_trust
 * interrupts, such as due to messages from the VF using the virtchnl
   communication
 * processing such as device reset
 * commands to add or remove VFs

The current implementation does not keep track of when all threads are
done operating on a VF and can potentially result in use-after-free
issues caused by one thread accessing a VF structure after it has been
released when removing VFs. Some of these are prevented with various
state flags and checks.

In addition, this structure is quite static and does not support a
planned future where virtualization can be more dynamic. As we begin to
look at supporting Scalable IOV with the ice driver (as opposed to just
supporting Single Root IOV), this structure is not sufficient.

In the future, VFs will be able to be added and removed individually and
dynamically.

To allow for this, and to better protect against a whole class of
use-after-free bugs, replace the VF storage with a combination of a hash
table and krefs to reference track all of the accesses to VFs through
the hash table.

A hash table still allows efficient look up of the VF given its ID, but
also allows adding and removing VFs. It does not require contiguous VF
IDs.

The use of krefs allows the cleanup of the VF memory to be delayed until
after all threads have released their reference (by calling ice_put_vf).

To prevent corruption of the hash table, a combination of RCU and the
mutex table_lock are used. Addition and removal from the hash table use
the RCU-aware hash macros. This allows simple read-only look ups that
iterate to locate a single VF can be fast using RCU. Accesses which
modify the hash table, or which can't take RCU because they sleep, will
hold the mutex lock.

By using this design, we have a stronger guarantee that the VF structure
can't be released until after all threads are finished operating on it.
We also pave the way for the more dynamic Scalable IOV implementation in
the future.

Before we switch the VF data structure storage mechanism to a hash,
introduce new accessor functions to define the new interface.

* ice_get_vf_by_id is a function used to obtain a reference to a VF from
  the table based on its VF ID
* ice_has_vfs is used to quickly check if any VFs are configured
* ice_get_num_vfs is used to get an exact count of how many VFs are
  configured

We can drop the old ice_validate_vf_id function, since every caller was
just going to immediately access the VF table to get a reference
anyways. This way we simply use the single ice_get_vf_by_id to both
validate the VF ID is within range and that there exists a VF with that
ID.

This change enables us to more easily convert the codebase to the hash
table since most callers now properly use the interface.

The ice_for_each_vf macro is intended to be used to loop over all VFs.
The current implementation relies on an iterator that is the index into
the VF array in the PF structure. This forces all users to perform a
look up themselves.

This abstraction forces a lot of duplicate work on callers and leaks the
interface implementation to the caller. Replace this with an
implementation that includes the VF pointer the primary iterator. This
version simplifies callers which just want to iterate over every VF, as
they no longer need to perform their own lookup.

The "i" iterator value is replaced with a new unsigned int "bkt"
parameter, as this will match the necessary interface for replacing
the VF array with a hash table. For now, the bkt is the VF ID, but in
the future it will simply be the hash bucket index. Document that it
should not be treated as a VF ID.

This change aims to simplify switching from the array to a hash table. I
considered alternative implementations such as an xarray but decided
that the hash table was the simplest and most suitable implementation. I
also looked at methods to hide the bkt iterator entirely, but I couldn't
come up with a feasible solution that worked for hash table iterators.
