The version information is at the bit31 ~ bit16 in the VERID
register, so need to right shift 16bit to get it, otherwise
the result of comparison "sai->verid.version >= 0x0301" is
wrong.

This patch passes the full response so that the audit function can use all
of it. The audit function was updated to log the additional information in
the AUDIT_FANOTIFY record.
Currently the only type of fanotify info that is defined is an audit
rule number, but convert it to hex encoding to future-proof the field.
Hex encoding suggested by Paul Moore <paul@paul-moore.com>.
The {subj,obj}_trust values are {0,1,2}, corresponding to no, yes, unknown.
Sample records:
type=FANOTIFY msg=audit(1600385147.372:590): resp=2 fan_type=1 fan_info=3137 subj_trust=3 obj_trust=5
type=FANOTIFY msg=audit(1659730979.839:284): resp=1 fan_type=0 fan_info=0 subj_trust=2 obj_trust=2

This patch adds a flag, FAN_INFO and an extensible buffer to provide
additional information about response decisions. The buffer contains
one or more headers defining the information type and the length of the
following information. The patch defines one additional information
type, FAN_RESPONSE_INFO_AUDIT_RULE, to audit a rule number. This will
allow for the creation of other information types in the future if other
users of the API identify different needs.
The kernel can be tested if it supports a given info type by supplying
the complete info extension but setting fd to FAN_NOFD. It will return
the expected size but not issue an audit record.

Filter which excludes samples matching the event filter. The feature
mirrors the existing event filter in PMSEVFR_EL1 adding a new register,

comprehensive
We have two IS1 filters of the OCELOT_VCAP_KEY_ANY key type (the one with
"action vlan pop" and the one with "action vlan modify") and one of the
OCELOT_VCAP_KEY_IPV4 key type (the one with "action skbedit priority").
But we have no IS1 filter with the OCELOT_VCAP_KEY_ETYPE key type, and
there was an uncaught breakage there.
To increase test coverage, convert one of the OCELOT_VCAP_KEY_ANY
filters to OCELOT_VCAP_KEY_ETYPE, by making the filter also match on the
MAC SA of the traffic sent by mausezahn, $h1_mac.

Alternative short title: don't instruct the hardware to match on
EtherType with "protocol 802.1Q" flower filters. It doesn't work for the
reasons detailed below.
With a command such as the following:
tc filter add dev $swp1 ingress chain $(IS1 2) pref 3 \
protocol 802.1Q flower skip_sw vlan_id 200 src_mac $h1_mac \
action vlan modify id 300 \
action goto chain $(IS2 0 0)
the created filter is set by ocelot_flower_parse_key() to be of type
OCELOT_VCAP_KEY_ETYPE, and etype is set to {value=0x8100, mask=0xffff}.
This gets propagated all the way to is1_entry_set() which commits it to
hardware (the VCAP_IS1_HK_ETYPE field of the key). Compare this to the
case where src_mac isn't specified - the key type is OCELOT_VCAP_KEY_ANY,
and is1_entry_set() doesn't populate VCAP_IS1_HK_ETYPE.
The problem is that for VLAN-tagged frames, the hardware interprets the
ETYPE field as holding the encapsulated VLAN protocol. So the above
filter will only match those packets which have an encapsulated protocol
of 0x8100, rather than all packets with VLAN ID 200 and the given src_mac.
The reason why this is allowed to occur is because, although we have a
block of code in ocelot_flower_parse_key() which sets "match_protocol"
to false when VLAN keys are present, that code executes too late.
There is another block of code, which executes for Ethernet addresses,
and has a "goto finished_key_parsing" and skips the VLAN header parsing.
By skipping it, "match_protocol" remains with the value it was
initialized with, i.e. "true", and "proto" is set to f->common.protocol,
or 0x8100.
The concept of ignoring some keys rather than erroring out when they are
present but can't be offloaded is dubious in itself, but is present
since the initial commit fe3490e6107e ("net: mscc: ocelot: Hardware
ofload for tc flower filter"), and it's outside of the scope of this
patch to change that.
The problem was introduced when the driver started to interpret the
flower filter's protocol, and populate the VCAP filter's ETYPE field
based on it.
To fix this, it is sufficient to move the code that parses the VLAN keys
earlier than the "goto finished_key_parsing" instruction. This will
ensure that if we have a flower filter with both VLAN and Ethernet
address keys, it won't match on ETYPE 0x8100, because the VLAN key
parsing sets "match_protocol = false".

memblock_free_late()."
This reverts commit 115d9d77bb0f9152c60b6e8646369fa7f6167593.
The pages being freed by memblock_free_late() have already been
initialized, but if they are in the deferred init range,
__free_one_page() might access nearby uninitialized pages when trying to
coalesce buddies. This can, for example, trigger this BUG:

Frank reports that in a mt7530 setup where some ports are standalone and
some are in a VLAN-aware bridge, 8021q uppers of the standalone ports
lose their VLAN tag on xmit, as seen by the link partner.
This seems to occur because once the other ports join the VLAN-aware
bridge, mt7530_port_vlan_filtering() also calls
mt7530_port_set_vlan_aware(ds, cpu_dp->index), and this affects the way
that the switch processes the traffic of the standalone port.
Relevant is the PVC_EG_TAG bit. The MT7530 documentation says about it:
EG_TAG: Incoming Port Egress Tag VLAN Attribution
0: disabled (system default)
1: consistent (keep the original ingress tag attribute)
My interpretation is that this setting applies on the ingress port, and
"disabled" is basically the normal behavior, where the egress tag format
of the packet (tagged or untagged) is decided by the VLAN table
(MT7530_VLAN_EGRESS_UNTAG or MT7530_VLAN_EGRESS_TAG).
But there is also an option of overriding the system default behavior,
and for the egress tagging format of packets to be decided not by the
VLAN table, but simply by copying the ingress tag format (if ingress was
tagged, egress is tagged; if ingress was untagged, egress is untagged;
aka "consistent). This is useful in 2 scenarios:
- VLAN-unaware bridge ports will always encounter a miss in the VLAN
table. They should forward a packet as-is, though. So we use
"consistent" there. See commit e045124e9399 ("net: dsa: mt7530: fix
tagged frames pass-through in VLAN-unaware mode").
- Traffic injected from the CPU port. The operating system is in god
mode; if it wants a packet to exit as VLAN-tagged, it sends it as
VLAN-tagged. Otherwise it sends it as VLAN-untagged*.
*This is true only if we don't consider the bridge TX forwarding offload
feature, which mt7530 doesn't support.
So for now, make the CPU port always stay in "consistent" mode to allow
software VLANs to be forwarded to their egress ports with the VLAN tag
intact, and not stripped.

it was intended to remove the kobject_del for srv_path->kobj.

We reference dump buffers both by their handle as well as their
object. The problem is now that when anybody iterates over the DRM
framebuffers and exports the underlying GEM objects through DMA-buf
we run into a circular reference count situation.
The result is that the fbdev handling holds the GEM handle preventing
the DMA-buf in the GEM object to be released. This DMA-buf in turn
holds a reference to the driver module which on unload would release
the fbdev.
Break that loop by releasing the handle as soon as the DRM
framebuffer object is created. The DRM framebuffer and the DRM client
buffer structure still hold a reference to the underlying GEM object
preventing its destruction.

Use actual CPU number instead of hardcoded value to decide the size
of 'cpu_used_mask' in 'struct sw_flow'. Below is the reason.
'struct cpumask cpu_used_mask' is embedded in struct sw_flow.
Its size is hardcoded to CONFIG_NR_CPUS bits, which can be
8192 by default, it costs memory and slows down ovs_flow_alloc.
To address this:
Redefine cpu_used_mask to pointer.
Append cpumask_size() bytes after 'stat' to hold cpumask.
Initialization cpu_used_mask right after stats_last_writer.
APIs like cpumask_next and cpumask_set_cpu never access bits
beyond cpu count, cpumask_size() bytes of memory is enough.

Ideally there should not be any forward declarations here, which
would make it easier to show that there is no unbounded recursion.
I tried fixing this but could not figure out how to avoid the
recursive call.
As a hotfix, address only the broken prototype to fix the build
problem instead.

Ajit Khaparde says:
====================
bnxt: Add Auxiliary driver support
Add auxiliary device driver for Broadcom devices.
The bnxt_en driver will register and initialize an aux device
if RDMA is enabled in the underlying device.
The bnxt_re driver will then probe and initialize the
RoCE interfaces with the infiniband stack.
We got rid of the bnxt_en_ops which the bnxt_re driver used to
communicate with bnxt_en.
Similarly We have tried to clean up most of the bnxt_ulp_ops.
In most of the cases we used the functions and entry points provided
by the auxiliary bus driver framework.
And now these are the minimal functions needed to support the functionality.
We will try to work on getting rid of the remaining if we find any
other viable option in future.
* 'aux-bus-v11' of https://github.com/ajitkhaparde1/linux:
bnxt_en: Remove runtime interrupt vector allocation
RDMA/bnxt_re: Remove the sriov config callback
bnxt_en: Remove struct bnxt access from RoCE driver
bnxt_en: Use auxiliary bus calls over proprietary calls
bnxt_en: Use direct API instead of indirection
bnxt_en: Remove usage of ulp_id
RDMA/bnxt_re: Use auxiliary driver interface
bnxt_en: Add auxiliary driver support

Not all decoders have a reset callback.
The CXL specification allows a host bridge with a single root port to
have no explicit HDM decoders. Currently the region driver assumes there
are none. As such the CXL core creates a special pass through decoder
instance without a commit/reset callback.
Prior to this patch, the ->reset() callback was called unconditionally when
calling cxl_region_decode_reset. Thus a configuration with 1 Host Bridge,
1 Root Port, and one directly attached CXL type 3 device or multiple CXL
type 3 devices attached to downstream ports of a switch can cause a null
pointer dereference.
Before the fix, a kernel crash was observed when we destroy the region, and
a pass through decoder is reset.
The issue can be reproduced as below,
1) create a region with a CXL setup which includes a HB with a
single root port under which a memdev is attached directly.
2) destroy the region with cxl destroy-region regionX -f.

The RFI and STF security mitigation options can flip the
interrupt_exit_not_reentrant static branch condition concurrently with
the interrupt exit code which tests that branch.
Interrupt exit tests this condition to set MSR[EE|RI] for exit, then
again in the case a soft-masked interrupt is found pending, to recover
the MSR so the interrupt can be replayed before attempting to exit
again. If the condition changes between these two tests, the MSR and irq
soft-mask state will become corrupted, leading to warnings and possible
crashes. For example, if the branch is initially true then false,
MSR[EE] will be 0 but PACA_IRQ_HARD_DIS clear and EE may not get
enabled, leading to warnings in irq_64.c.

The > comparison should be >= to prevent reading one element beyond

The "vsi->num_rxq" is not strictly speaking the number of elements in
the vsi->rxq_map[] array. The array has "vsi->alloc_rxq" elements and
"vsi->num_rxq" is less than or equal to the number of elements in the

If the user turns on the vf-true-promiscuous-support flag, then Rx VLAN
filtering will be disabled if the VF requests to enable promiscuous
mode. When the VF is in a port VLAN, this is the incorrect behavior
because it will allow the VF to receive traffic outside of its port VLAN
domain. Fortunately this only resulted in the VF(s) receiving broadcast
traffic outside of the VLAN domain because all of the VLAN promiscuous
rules are based on the port VLAN ID. Fix this by setting the
.disable_rx_filtering VLAN op to a no-op when a port VLAN is enabled on
the VF.
Also, make sure to make this fix for both Single VLAN Mode and Double
VLAN Mode enabled devices.

workqueue being allocated with the WQ_MEM_RECLAIM flag and the irdma one
is not.
According to kernel documentation, this flag should be set if the

Since it is not, there is no need for the ice driver's WQ to have this

In a previous commit, Ubuntu kernel code version is correctly set
by retrieving the information from /proc/version_signature.
commit<5b3d72987701d51bf31823b39db49d10970f5c2d>
(libbpf: Improve LINUX_VERSION_CODE detection)
The /proc/version_signature file doesn't present in at least the
older versions of Debian distributions (eg, Debian 9, 10). The Debian
kernel has a similar issue where the release information from uname()
syscall doesn't give the kernel code version that matches what the
kernel actually expects. Below is an example content from Debian 10.
release: 4.19.0-23-amd64
version: #1 SMP Debian 4.19.269-1 (2022-12-20) x86_64
Debian reports incorrect kernel version in utsname::release returned
by uname() syscall, which in older kernels (Debian 9, 10) leads to
kprobe BPF programs failing to load due to the version check mismatch.
Fortunately, the correct kernel code version presents in the
utsname::version returned by uname() syscall in Debian kernels. This
change adds another get kernel version function to handle Debian in
addition to the previously added get kernel version function to handle
Ubuntu. Some minor refactoring work is also done to make the code more
readable.

When logging a directory, we always set the inode's last_dir_index_offset
to the offset of the last dir index item we found. This is using an extra
field in the log context structure, and it makes more sense to update it
only after we insert dir index items, and we could directly update the
inode's last_dir_index_offset field instead.
So make this simpler by updating the inode's last_dir_index_offset only
when we actually insert dir index keys in the log tree, and getting rid
of the last_dir_item_offset field in the log context structure.

Pull cgroup fixes from Tejun Heo:
"During the v6.2 cycle, there were a series of changes to task cpu
affinity handling which fixed cpuset inadvertently clobbering
user-configured affinity masks. Unfortunately, they broke the affinity
handling on hybrid heterogeneous CPUs which have cores that can
execute both 64 and 32bit along with cores that can only execute 32bit
code.
This contains two fix patches for the above issue. While reverting the
changes that caused the regression is definitely an option, the
origial patches do improve how cpuset behave signficantly in some
cases and the fixes seem fairly safe, so I think it'd be better to try
to fix them first"

set_cpus_allowed_ptr() will fail with -EINVAL if the requested
affinity mask is not a subset of the task_cpu_possible_mask() for the
task being updated. Consequently, on a heterogeneous system with cpusets
spanning the different CPU types, updates to the cgroup hierarchy can
silently fail to update task affinities when the effective affinity
mask for the cpuset is expanded.
For example, consider an arm64 system with 4 CPUs, where CPUs 2-3 are
the only cores capable of executing 32-bit tasks. Attaching a 32-bit
task to a cpuset containing CPUs 0-2 will correctly affine the task to
CPU 2. Extending the cpuset to CPUs 0-3, however, will fail to extend
the affinity mask of the 32-bit task because update_tasks_cpumask() will
pass the full 0-3 mask to set_cpus_allowed_ptr().
Extend update_tasks_cpumask() to take a temporary 'cpumask' paramater
and use it to mask the 'effective_cpus' mask with the possible mask for
each task being updated.

cpuset tasks
Since commit 8f9ea86fdf99 ("sched: Always preserve the user
requested cpumask"), relax_compatible_cpus_allowed_ptr() is calling
__sched_setaffinity() unconditionally. This helps to expose a bug in
the current cpuset hotplug code where the cpumasks of the tasks in
the top cpuset are not updated at all when some CPUs become online or
offline. It is likely caused by the fact that some of the tasks in the
top cpuset, like percpu kthreads, cannot have their cpu affinity changed.
One way to reproduce this as suggested by Peter is:
- boot machine
- offline all CPUs except one
- taskset -p ffffffff $$
- online all CPUs
Fix this by allowing cpuset_cpus_allowed() to return a wider mask that
includes offline CPUs for those tasks that are in the top cpuset. For
tasks not in the top cpuset, the old rule applies and only online CPUs
will be returned in the mask since hotplug events will update their
cpumasks accordingly.

Here the subtest "BPF prologue generation" failed and logs shows
debuginfo is needed. After installing kernel-debuginfo package, testcase
passes.
The "BPF prologue generation" subtest failed because, the do_test()
returns TEST_FAIL without checking the error type returned by
parse_events_load_bpf_obj().
parse_events_load_bpf_obj() can also return error of type -ENODATA
