In preparation for subsequent changes, introduce a specialized variant
of async_schedule_dev() that will not invoke the argument function
synchronously when it cannot be scheduled for asynchronous execution.
The new function, async_schedule_dev_nocall(), will be used for fixing

This fixes openvswitch's handling of nat packets in the related state.
In nf_ct_nat_execute(), which is called from nf_ct_nat(), ICMP/ICMPv6
packets in the IP_CT_RELATED or IP_CT_RELATED_REPLY state, which have
not been dropped, will follow the goto, however the placement of the
goto label means that updating the action bit field will be bypassed.
This causes ovs_nat_update_key() to not be called from ovs_ct_nat()
which means the openvswitch match key for the ICMP/ICMPv6 packet is not
updated and the pre-nat value will be retained for the key, which will
result in the wrong openflow rule being matched for that packet.
Move the goto label above where the action bit field is being set so
that it is updated in all cases where the packet is accepted.

The flag DMA_TX_APPEND_CRC was only written to the first DMA descriptor
in the TX path, where each descriptor corresponds to a single skbuff
fragment (or the skbuff head). This led to packets with no FCS appearing
on the wire if the kernel allocated the packet in fragments, which would
always happen when using PACKET_MMAP/TPACKET (cf. tpacket_fill_skb() in
net/af_packet.c).

Commit 13e59344fb9d ("net: ethtool: add support for symmetric-xor RSS hash")
adds a check to the ethtool set_rxnfc operation, which checks the RX
flow hash if the flag RXH_XFRM_SYM_XOR is set. This flag is introduced
with the same commit. It calls the ethtool get_rxfh operation to get the
RX flow hash data. If get_rxfh is not supported, then EOPNOTSUPP is
returned.
There are driver like tsnep, macb, asp2, genet, gianfar, mtk, ... which
support the ethtool operation set_rxnfc but not get_rxfh. This results
in EOPNOTSUPP returned by ethtool_set_rxnfc() without actually calling
the ethtool operation set_rxnfc. Thus, set_rxnfc got broken for all
these drivers.
Check RX flow hash in ethtool_set_rxnfc() only if driver supports RX
flow hash.

listener subflows. This is a correction for a patch introduced in v6.4
which was fixing an issue from v5.17.

The MPTCP protocol does not expect that any other entity could change
the first subflow status when such socket is listening.
Unfortunately the TCP diag interface allows aborting any TCP socket,
including MPTCP listeners subflows. As reported by syzbot, that trigger
a WARN() and could lead to later bigger trouble.
The MPTCP protocol needs to do some MPTCP-level cleanup actions to
properly shutdown the listener. To keep the fix simple, prevent
entirely the diag interface from stopping such listeners.
We could refine the diag callback in a later, larger patch targeting
net-next.

A flag was needed to denote which eventfs_inode was the "events"
directory, so a bit was taken from the "nr_entries" field, as there's not
that many entries, and 2^30 is plenty. But the bit number for nr_entries
was not updated to reflect the bit taken from it, which would add an
unnecessary integer to the structure.

If a getdents() is called on the tracefs directory but does not get all
the files, it can leave a "cursor" dentry in the d_subdirs list of tracefs
dentry. This cursor dentry does not have a d_inode for it. Before
referencing tracefs_inode from the dentry, the d_inode must first be
checked if it has content. If not, then it's not a tracefs_inode and can
be ignored.
The following caused a crash:
#define getdents64(fd, dirp, count) syscall(SYS_getdents64, fd, dirp, count)
#define BUF_SIZE 256
#define TDIR "/tmp/file0"
int main(void)
{
char buf[BUF_SIZE];
int fd;
int n;
mkdir(TDIR, 0777);
mount(NULL, TDIR, "tracefs", 0, NULL);
fd = openat(AT_FDCWD, TDIR, O_RDONLY);
n = getdents64(fd, buf, BUF_SIZE);
ret = mount(NULL, TDIR, NULL, MS_NOSUID|MS_REMOUNT|MS_RELATIME|MS_LAZYTIME,
"gid=1000");
return 0;
}
That's because the 256 BUF_SIZE was not big enough to read all the
dentries of the tracefs file system and it left a "cursor" dentry in the
subdirs of the tracefs root inode. Then on remounting with "gid=1000",
it would cause an iteration of all dentries which hit:
ti = get_tracefs(dentry->d_inode);
if (ti && (ti->flags & TRACEFS_EVENT_INODE))
eventfs_update_gid(dentry, gid);
Which crashed because of the dereference of the cursor dentry which had a NULL
d_inode.
In the subdir loop of the dentry lookup of set_gid(), if a child has a
NULL d_inode, simply skip it.

Add const modifier to function parameters and variables where appropriate
in ice_base.c and corresponding declarations in ice_base.h.
The reason for starting the change is that read-only pointers should be
marked as const when possible to allow for smoother and more optimal code
generation and optimization as well as allowing the compiler to warn the
developer about potentially unwanted modifications, while not carrying
noticeable negative impact.

It was found that this statistic is incorrectly
reported by HW and thus, useless.
As RX length error statistics are shown to the
end user when requested, the values reported
are misleading.
Thus, that value is no longer reported and
doesn't count anymore when adding all rx errors.

The ice_vf_create_vsi() function and its VF ops helper introduced by commit
a4c785e8162e ("ice: convert vf_ops .vsi_rebuild to .create_vsi") are used
during an individual VF reset to re-create the VSI. This was done in order
to ensure that the VSI gets properly reconfigured within the hardware.
This is somewhat heavy handed as we completely release the VSI memory and
structure, and then create a new VSI. This can also potentially force a
change of the VSI index as we will re-use the first open slot in the VSI
array which may not be the same.
As part of implementing devlink reload, commit 6624e780a577 ("ice: split
ice_vsi_setup into smaller functions") split VSI setup into smaller
functions, introducing both ice_vsi_cfg() and ice_vsi_decfg() which can be
used to configure or deconfigure an existing software VSI structure.
Rather than completely removing the VSI and adding a new one using the
.create_vsi() VF operation, simply use ice_vsi_decfg() to remove the
current configuration. Save the VSI type and then call ice_vsi_cfg() to
reconfigure the VSI as the same type that it was before.
The existing reset logic assumes that all hardware filters will be removed,
so also call ice_fltr_remove_all() before re-configuring the VSI.
This new operation does not re-create the VSI, so rename it to
ice_vf_reconfig_vsi().
The new approach can safely share the exact same flow for both SR-IOV VFs
as well as the Scalable IOV VFs being worked on. This uses less code and is
a better abstraction over fully deleting the VSI and adding a new one.

Switchdev mode allows to add mirroring rules to mirror incoming and
outgoing packets to the interface's port representor. Previously, this was
available only using software functionality. Add possibility to offload
this functionality to the NIC hardware.
Introduce ICE_MIRROR_PACKET filter action to the ice_sw_fwd_act_type enum
to identify the desired action and pass it to the hardware as well as the
VSI to mirror.
Example of tc mirror command using hardware:
tc filter add dev ens1f0np0 ingress protocol ip prio 1 flower src_mac
b4:96:91:a5:c7:a7 skip_sw action mirred egress mirror dev eth1
ens1f0np0 - PF

Introduce new capability - Low Latency Timestamping with Interrupt.
On supported devices, driver can request a single timestamp from FW
without polling the register afterwards. Instead, FW can issue
a dedicated interrupt when the timestamp was read from the PHY register
and its value is available to read from the register.
This eliminates the need of bottom half scheduling, which results in
minimal delay for timestamping.
For this mode, allocate TS indices sequentially, so that timestamps are
always completed in FIFO manner.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Decoding an invalid address with certain firmware decoders could
cause a #PF (Page Fault) in the EFI runtime context, which could
subsequently hang the system. To make {i10nm,skx}_edac more robust
against such bogus firmware decoders, filter out invalid addresses
before allowing the firmware decoder to process them.
