Add a possible_interfaces member to struct phy_device to indicate which
interfaces a clause 45 PHY may switch between depending on the media.
This must be populated by the PHY driver by the time the .config_init()
method completes according to the PHYs host-side configuration.
For example, the Marvell 88x3310 PHY can switch between 10GBASE-R,
5GBASE-R, 2500BASE-X, and SGMII on the host side depending on the media
side speed, so all these interface modes are set in the
possible_interfaces member.
This allows phylib users (such as phylink) to know in advance which
interface modes to expect, which allows them to appropriately restrict
the advertised link modes according to the capabilities of other parts
of the link.

Provide phy driver start/stop hooks so that the PHY driver knows when
the network driver is starting or stopping. This will be used for the
Marvell 10G driver so that we can sanely refuse to start if the PHYs
firmware is not present, and also so that we can sanely support SFPs
behind the PHY.

Allow phylib drivers to pass the hardware-resolved pause state to MAC

There are several places which open code comparing PHY IDs. Provide a
couple of helpers to assist with this, using a slightly simpler test
than the original:
- phy_id_compare() compares two arbitary PHY IDs and a mask of the
significant bits in the ID.
- phydev_id_compare() compares the bound phydev with the specified
PHY ID, using the bound driver's mask.

We currently parse the SFP EEPROM to a bitmap of ethtool link modes,
and then attempt to convert the link modes to a PHY interface mode.
While this works at present, there are cases where this is sub-optimal.
For example, where a module can operate with several different PHY
interface modes.
To start addressing this, arrange for the SFP EEPROM parsing to also
provide a bitmap of the possible PHY interface modes.

The mac_an_restart() method is now completely unused, and has been
superseded by phylink_pcs support. Remove this method.
Since phylink_pcs_mac_an_restart() now only deals with the PCS, rename
the function to remove the _mac infix.

All drivers are now updated for the March 2020 changes, and no longer
make use of the mac_pcs_get_state() or mac_an_restart() operations,
which are now NULL across all DSA drivers. All DSA drivers don't look
at speed, duplex, pause or advertisement in their phylink_mac_config()
method either.
Remove support for these operations from DSA, and stop marking DSA as
a legacy driver by default.

Add DSA support for the phylink mac_prepare() and mac_finish() calls.
These were introduced as part of the PCS support to allow MACs to
perform preparatory steps prior to configuration, and finalisation
steps after the MAC and PCS has been configured.
Introducing phylink_pcs support to the mv88e6xxx DSA driver needs some
code moved out of its mac_config() stage into the mac_prepare() and
mac_finish() stages, and this commit facilitates such code in DSA
drivers.

====================
Netfilter fixes for net
1) Reduce number of hardware offload retries from flowtable datapath
which might hog system with retries, from Felix Fietkau.
2) Skip neighbour lookup for PPPoE device, fill_forward_path() already
provides this and set on destination address from fill_forward_path for
PPPoE device, also from Felix.
4) When combining PPPoE on top of a VLAN device, set info->outdev to the
PPPoE device so software offload works, from Felix.
5) Fix TCP teardown flowtable state, races with conntrack gc might result
in resetting the state to ESTABLISHED and the time to one day. Joint
work with Oz Shlomo and Sven Auhagen.
6) Call dst_check() from flowtable datapath to check if dst is stale
instead of doing it from garbage collector path.
7) Disable register tracking infrastructure, either user-space or
kernel need to pre-fetch keys inconditionally, otherwise register
tracking assumes data is already available in register that might
not well be there, leading to incorrect reductions.

request_reinit() is not only ugly as the comment rightfully suggests,
but also unsafe. Even though it is called with osdc->lock held for
write in all cases, resetting the OSD request refcount can still race
with handle_reply() and result in use-after-free. Taking linger ping
as an example:
handle_timeout thread handle_reply thread
down_read(&osdc->lock)
req = lookup_request(...)
...
finish_request(req) # unregisters
up_read(&osdc->lock)
__complete_request(req)
linger_ping_cb(req)
# req->r_kref == 2 because handle_reply still holds its ref
down_write(&osdc->lock)
send_linger_ping(lreq)
req = lreq->ping_req # same req
# cancel_linger_request is NOT
# called - handle_reply already
# unregistered
request_reinit(req)
WARN_ON(req->r_kref != 1) # fires
request_init(req)
kref_init(req->r_kref)
# req->r_kref == 1 after kref_init
ceph_osdc_put_request(req)
kref_put(req->r_kref)
# req->r_kref == 0 after kref_put, req is freed
<further req initialization/use> !!!
This happens because send_linger_ping() always (re)uses the same OSD
request for watch ping requests, relying on cancel_linger_request() to
unregister it from the OSD client and rip its messages out from the
messenger. send_linger() does the same for watch/notify registration
and watch reconnect requests. Unfortunately cancel_request() doesn't
guarantee that after it returns the OSD client would be completely done
with the OSD request -- a ref could still be held and the callback (if
specified) could still be invoked too.
The original motivation for request_reinit() was inability to deal with
allocation failures in send_linger() and send_linger_ping(). Switching
to using osdc->req_mempool (currently only used by CephFS) respects that
and allows us to get rid of request_reinit().

Not calling the function for dummy contexts will cause the context to
not be reset. During the next syscall, this will cause an error in
__audit_syscall_entry:
WARN_ON(context->context != AUDIT_CTX_UNUSED);
WARN_ON(context->name_count);
if (context->context != AUDIT_CTX_UNUSED || context->name_count) {
audit_panic("unrecoverable error in audit_syscall_entry()");
return;
}
These problematic dummy contexts are created via the following call
chain:
exit_to_user_mode_prepare

In IPv4 setting the "disable_policy" flag on a device means no policy
should be enforced for traffic originating from the device. This was
implemented by seting the DST_NOPOLICY flag in the dst based on the
originating device.
However, dsts are cached in nexthops regardless of the originating
devices, in which case, the DST_NOPOLICY flag value may be incorrect.
Consider the following setup:
+------------------------------+
| ROUTER |
+-------------+ | +-----------------+ |
| ipsec src |----|-|ipsec0 | |
+-------------+ | |disable_policy=0 | +----+ |
| +-----------------+ |eth1|-|-----
+-------------+ | +-----------------+ +----+ |
| noipsec src |----|-|eth0 | |
+-------------+ | |disable_policy=1 | |
| +-----------------+ |
+------------------------------+
Where ROUTER has a default route towards eth1.
dst entries for traffic arriving from eth0 would have DST_NOPOLICY
and would be cached and therefore can be reused by traffic originating
from ipsec0, skipping policy check.
Fix by setting a IPSKB_NOPOLICY flag in IPCB and observing it instead
of the DST in IN/FWD IPv4 policy checks.

d507204d3c5cc57d9a8bdf0a477615bb59ea1611 ("tcp/dccp: add tw->tw_bslot")
As Leonard pointed out, a newly allocated netns can happen
to reuse a freed 'struct net'.
While TCP TW timers were covered by my patches, other things were not:
1) Lookups in rx path (INET_MATCH() and INET6_MATCH()), as they look
at 4-tuple plus the 'struct net' pointer.
2) /proc/net/tcp[6] and inet_diag, same reason.
3) hashinfo->bhash[], same reason.
Fixing all this seems risky, lets instead revert.
In the future, we might have a per netns tcp hash table, or
a per netns list of timewait sockets...

Set a size limit of 8 bytes of the written buffer to "hdev->name"
including the terminating null byte, as the size of "hdev->name" is 8
bytes. If an id value which is greater than 9999 is allocated,
then the "snprintf(hdev->name, sizeof(hdev->name), "hci%d", id)"
function call would lead to a truncation of the id value in decimal
notation.
Set an explicit maximum id parameter in the id allocation function call.
The id allocation function defines the maximum allocated id value as the
maximum id parameter value minus one. Therefore, HCI_MAX_ID is defined
as 10000.

Commit fa2c3254d7cf (sched/tracing: Don't re-read p->state when emitting
sched_switch event, 2022-01-20) added a new prev_state argument to the
sched_switch tracepoint, before the prev task_struct pointer.
This reordering of arguments broke BPF programs that use the raw
tracepoint (e.g. tp_btf programs). The type of the second argument has
changed and existing programs that assume a task_struct* argument
(e.g. for bpf_task_storage access) will now fail to verify.
If we instead append the new argument to the end, all existing programs
would continue to work and can conditionally extract the prev_state
argument on supported kernel versions.

Currently pedit tries to ensure that the accessed skb offset
is writable via skb_unclone(). The action potentially allows
touching any skb bytes, so it may end-up modifying shared data.
The above causes some sporadic MPTCP self-test failures, due to
this code:
tc -n $ns2 filter add dev ns2eth$i egress \
protocol ip prio 1000 \
handle 42 fw \
action pedit munge offset 148 u8 invert \
pipe csum tcp \
index 100
The above modifies a data byte outside the skb head and the skb is
a cloned one, carrying a TCP output packet.
This change addresses the issue by keeping track of a rough
over-estimate highest skb offset accessed by the action and ensuring
such offset is really writable.
Note that this may cause performance regressions in some scenarios,
but hopefully pedit is not in the critical path.

The definition of RFKILL_IOCTL_MAX_SIZE introduced by commit
54f586a91532 ("rfkill: make new event layout opt-in") is unusable
since it is based on RFKILL_IOC_EXT_SIZE which has not been defined.
Fix that by replacing the undefined constant with the constant which
is intended to be used in this definition.

The last two users were floppy.c and ataflop.c respectively, it was
verified that no other drivers makes use of this, so let's remove it.

This reverts commit 892de36fd4a98fab3298d417c051d9099af5448d.
The gssproxy server is unresponsive when it calls into the kernel to
start the upcall service, so it will not reply to our RPC ping at all.
