Add support to update the CMRT and control firmware as well as the UEFI
driver on fbnic using devlink dev flash.
Make sure the shutdown / quiescence paths like suspend take the devlink
lock to prevent them from interrupting the FW flashing process.

Add three new mailbox messages to support PLDM upgrades:
* FW_START_UPGRADE - Enables driver to request starting a firmware upgrade
by specifying the component to be upgraded and its
size.
* WRITE_CHUNK - Allows firmware to request driver to send a chunk of
data at the specified offset.
* FINISH_UPGRADE - Allows firmware to cancel the upgrade process and
return an error.

fbnic supports applying firmware which may not be rolled back. This is
implemented in firmware however it is useful for the driver to know the
minimum supported firmware version. This will enable the driver validate
new firmware before it is sent to the NIC. If it is too old the driver can
provide a clear message that the version is too old.

If ntuple filters count is modified followed by
unicast filters count using devlink then the ntuple count
set by user is ignored and all the ntuple filters are
being reallocated. Fix this by storing the ntuple count
set by user. Without this patch, say if user tries
to modify ntuple count as 8 followed by ucast filter count as 4
using devlink commands then ntuple count is being reverted to
default value 16 i.e, not retaining user set value 8.

====================
hv_netvsc: Fix error "nvsp_rndis_pkt_complete error status: 2"
Starting with commit dca5161f9bd0 in the 6.3 kernel, the Linux driver
for Hyper-V synthetic networking (netvsc) occasionally reports
"nvsp_rndis_pkt_complete error status: 2".[1] This error indicates
that Hyper-V has rejected a network packet transmit request from the
guest, and the outgoing network packet is dropped. Higher level
network protocols presumably recover and resend the packet so there is
no functional error, but performance is slightly impacted. Commit
dca5161f9bd0 is not the cause of the error -- it only added reporting
of an error that was already happening without any notice. The error
has presumably been present since the netvsc driver was originally
introduced into Linux.
This patch set fixes the root cause of the problem, which is that the
netvsc driver in Linux may send an incorrectly formatted VMBus message
to Hyper-V when transmitting the network packet. The incorrect
formatting occurs when the rndis header of the VMBus message crosses a
page boundary due to how the Linux skb head memory is aligned. In such
a case, two PFNs are required to describe the location of the rndis
header, even though they are contiguous in guest physical address
(GPA) space. Hyper-V requires that two PFNs be in a single "GPA range"
data struture, but current netvsc code puts each PFN in its own GPA
range, which Hyper-V rejects as an error in the case of the rndis
header.
The incorrect formatting occurs only for larger packets that netvsc
must transmit via a VMBus "GPA Direct" message. There's no problem
when netvsc transmits a smaller packet by copying it into a pre-
allocated send buffer slot because the pre-allocated slots don't have
page crossing issues.
After commit 14ad6ed30a10 in the 6.14 kernel, the error occurs much
more frequently in VMs with 16 or more vCPUs. It may occur every few
seconds, or even more frequently, in a ssh session that outputs a lot
of text. Commit 14ad6ed30a10 subtly changes how skb head memory is
allocated, making it much more likely that the rndis header will cross
a page boundary when the vCPU count is 16 or more. The changes in
commit 14ad6ed30a10 are perfectly valid -- they just had the side
effect of making the netvsc bug more prominent.
One fix is to check for adjacent PFNs in vmbus_sendpacket_pagebuffer()
and just combine them into a single GPA range. Such a fix is very
contained. But conceptually it is fixing the problem at the wrong
level. So this patch set takes the broader approach of maintaining
the already known grouping of contiguous PFNs at a higher level in
the netvsc driver code, and propagating that grouping down to the
creation of the VMBus message to send to Hyper-V. Maintaining the
grouping fixes this problem, and has the added benefit of allowing
netvsc_dma_map() to make fewer calls to dma_map_single() to do bounce
buffering in CoCo VMs.
Patch 1 is a preparatory change to allow vmbus_sendpacket_mpb_desc()
to specify multiple GPA ranges. In current code
vmbus_sendpacket_mpb_desc() is used only by the storvsc synthetic SCSI
driver, and it always creates a single GPA range.
Patch 2 updates the netvsc driver to use vmbus_sendpacket_mpb_desc()
instead of vmbus_sendpacket_pagebuffer(). Because the higher levels of
netvsc still don't group contiguous PFNs, this patch is functionally
neutral. The VMBus message to Hyper-V still has many GPA ranges, each
with a single PFN. But it lays the groundwork for the next patch.
Patch 3 changes the higher levels of netvsc to preserve the already
known grouping of contiguous PFNs. When the contiguous groupings are
passed to vmbus_sendpacket_mpb_desc(), GPA ranges containing multiple
PFNs are produced, as expected by Hyper-V. This is point at which the
core problem is fixed.
Patches 4 and 5 remove code that is no longer necessary after the
previous patches.
These changes provide a net reduction of about 65 lines of code, which
is an added benefit.
These changes have been tested in normal VMs, in SEV-SNP and TDX CoCo
VMs, and in Dv6-series VMs where the netvsp implementation is in the
OpenHCL paravisor instead of the Hyper-V host.
These changes are built against kernel version 6.15-rc6.

Starting with commit dca5161f9bd0 ("hv_netvsc: Check status in
SEND_RNDIS_PKT completion message") in the 6.3 kernel, the Linux
driver for Hyper-V synthetic networking (netvsc) occasionally reports
"nvsp_rndis_pkt_complete error status: 2".[1] This error indicates
that Hyper-V has rejected a network packet transmit request from the

dca5161f9bd0 is not the cause of the error -- it only added reporting
of an error that was already happening without any notice. The error
has presumably been present since the netvsc driver was originally
introduced into Linux.
The root cause of the problem is that the netvsc driver in Linux may
send an incorrectly formatted VMBus message to Hyper-V when
transmitting the network packet. The incorrect formatting occurs when
the rndis header of the VMBus message crosses a page boundary due to
how the Linux skb head memory is aligned. In such a case, two PFNs are
required to describe the location of the rndis header, even though
they are contiguous in guest physical address (GPA) space. Hyper-V
requires that two rndis header PFNs be in a single "GPA range" data
struture, but current netvsc code puts each PFN in its own GPA range,
which Hyper-V rejects as an error.
The incorrect formatting occurs only for larger packets that netvsc
must transmit via a VMBus "GPA Direct" message. There's no problem
when netvsc transmits a smaller packet by copying it into a pre-
allocated send buffer slot because the pre-allocated slots don't have
page crossing issues.
After commit 14ad6ed30a10 ("net: allow small head cache usage with
large MAX_SKB_FRAGS values") in the 6.14-rc4 kernel, the error occurs
much more frequently in VMs with 16 or more vCPUs. It may occur every
few seconds, or even more frequently, in an ssh session that outputs a
lot of text. Commit 14ad6ed30a10 subtly changes how skb head memory is
allocated, making it much more likely that the rndis header will cross
a page boundary when the vCPU count is 16 or more. The changes in
commit 14ad6ed30a10 are perfectly valid -- they just had the side
effect of making the netvsc bug more prominent.
Current code in init_page_array() creates a separate page buffer array
entry for each PFN required to identify the data to be transmitted.
Contiguous PFNs get separate entries in the page buffer array, and any
information about contiguity is lost.
Fix the core issue by having init_page_array() construct the page
buffer array to represent contiguous ranges rather than individual
pages. When these ranges are subsequently passed to
netvsc_build_mpb_array(), it can build GPA ranges that contain
multiple PFNs, as required to avoid the error "nvsp_rndis_pkt_complete
error status: 2". If instead the network packet is sent by copying
into a pre-allocated send buffer slot, the copy proceeds using the
contiguous ranges rather than individual pages, but the result of the
copying is the same. Also fix rndis_filter_send_request() to construct
a contiguous range, since it has its own page buffer array.
This change has a side benefit in CoCo VMs in that netvsc_dma_map()
calls dma_map_single() on each contiguous range instead of on each
page. This results in fewer calls to dma_map_single() but on larger
chunks of memory, which should reduce contention on the swiotlb.
Since the page buffer array now contains one entry for each contiguous
range instead of for each individual page, the number of entries in
the array can be reduced, saving 208 bytes of stack space in
netvsc_xmit() when MAX_SKG_FRAGS has the default value of 17.

netvsc currently uses vmbus_sendpacket_pagebuffer() to send VMBus
messages. This function creates a series of GPA ranges, each of which
contains a single PFN. However, if the rndis header in the VMBus
message crosses a page boundary, the netvsc protocol with the host
requires that both PFNs for the rndis header must be in a single "GPA
range" data structure, which isn't possible with
vmbus_sendpacket_pagebuffer(). As the first step in fixing this, add a
new function netvsc_build_mpb_array() to build a VMBus message with
multiple GPA ranges, each of which may contain multiple PFNs. Use
vmbus_sendpacket_mpb_desc() to send this VMBus message to the host.
There's no functional change since higher levels of netvsc don't
maintain or propagate knowledge of contiguous PFNs. Based on its
input, netvsc_build_mpb_array() still produces a separate GPA range
for each PFN and the behavior is the same as with
vmbus_sendpacket_pagebuffer(). But the groundwork is laid for a
subsequent patch to provide the necessary grouping.

vmbus_sendpacket_mpb_desc() is currently used only by the storvsc driver
and is hardcoded to create a single GPA range. To allow it to also be
used by the netvsc driver to create multiple GPA ranges, no longer
hardcode as having a single GPA range. Allow the calling driver to
specify the rangecount in the supplied descriptor.
Update the storvsc driver to reflect this new approach.

cpsw->slaves[slave_no].phy should be equal to netdev->phydev, because it
is assigned from phy_attach_direct(). The latter is indirectly called
from the two identically named cpsw_slave_open() functions, one in
cpsw.c and another in cpsw_new.c.
Thus, the driver should not need custom logic to find the PHY, the core
can find it, and phy_do_ioctl_running() achieves exactly that.
However, that is only the case for cpsw_new and for the cpsw driver in
dual EMAC mode. This is explained in more detail in the previous commit.
Thus, allow the simpler core logic to execute for cpsw_new, and move
cpsw_ndo_ioctl() to cpsw.c.

New timestamping API was introduced in commit 66f7223039c0 ("net: add
NDOs for configuring hardware timestamping") from kernel v6.6. It is
time to convert the two cpsw drivers to the new API, so that the
ndo_eth_ioctl() path can be removed completely.
The cpsw_hwtstamp_get() and cpsw_hwtstamp_set() methods (and their shim
definitions, for the case where CONFIG_TI_CPTS is not enabled) must have
their prototypes adjusted.
These methods are used by two drivers (cpsw and cpsw_new), with vastly
different configurations:
- cpsw has two operating modes:
- "dual EMAC" - enabled through the "dual_emac" device tree property -
creates one net_device per EMAC / slave interface (but there is no
bridging offload)
- "switch mode" - default - there is a single net_device, with two
EMACs/slaves behind it (and switching between them happens
unbeknownst to the network stack).
- cpsw_new always registers one net_device for each EMAC which doesn't
have status = "disabled". In terms of switching, it has two modes:
- "dual EMAC": default, no switching between ports, no switchdev
offload.
- "switch mode": enabled through the "switch_mode" devlink parameter,
offloads the Linux bridge through switchdev
Essentially, in 3 out of 4 operating modes, there is a bijective
relation between the net_device and the slave. Timestamping can thus be
configured on individual slaves. But in the "switch mode" of the cpsw
driver, ndo_eth_ioctl() targets a single slave, designated using the
"active_slave" device tree property.
To deal with these different cases, the common portion of the drivers,
cpsw_priv.c, has the cpsw_slave_index() function pointer, set to
separate, identically named cpsw_slave_index_priv() by the 2 drivers.
This is all relevant because cpsw_ndo_ioctl() has the old-style
phy_has_hwtstamp() logic which lets the PHY handle the timestamping
ioctls. Normally, that logic should be obsoleted by the more complex
logic in the core, which permits dynamically selecting the timestamp
provider - see dev_set_hwtstamp_phylib().
But I have doubts as to how this works for the "switch mode" of the dual
EMAC driver, because the core logic only engages if the PHY is visible
through ndev->phydev (this is set by phy_attach_direct()).
In cpsw.c, we have:
cpsw_ndo_open()
-> for_each_slave(priv, cpsw_slave_open, priv); // continues on errors
-> of_phy_connect()
-> phy_connect_direct()
-> phy_attach_direct()
OR
-> phy_connect()
-> phy_connect_direct()
-> phy_attach_direct()
The problem for "switch mode" is that the behavior of phy_attach_direct()
called twice in a row for the same net_device (once for each slave) is
probably undefined.
For sure it will overwrite dev->phydev. I don't see any explicit error
checks for this case, and even if there were, the for_each_slave() call
makes them non-fatal to cpsw_ndo_open() anyway.
I have no idea what is the extent to which this provides a usable
result, but the point is: only the last attached PHY will be visible
in dev->phydev, and this may well be a different PHY than
cpsw->slaves[slave_no].phy for the "active_slave".
In dual EMAC mode, as well as in cpsw_new, this should not be a problem.
I don't know whether PHY timestamping is a use case for the cpsw "switch
mode" as well, and I hope that there isn't, because for the sake of
simplicity, I've decided to deliberately break that functionality, by
refusing all PHY timestamping. Keeping it would mean blocking the old
API from ever being removed. In the new dev_set_hwtstamp_phylib() API,
it is not possible to operate on a phylib PHY other than dev->phydev,
and I would very much prefer not adding that much complexity for bizarre
driver decisions.
Final point about the cpsw_hwtstamp_get() conversion: we don't need to
propagate the unnecessary "config.flags = 0;", because dev_get_hwtstamp()
provides a zero-initialized struct kernel_hwtstamp_config.

misc drivers' sw timestamp changes
This series modified three outstanding drivers among more than 100 drivers
because the software timestamp generation is too early. The idea of this

MASCEC hardware block has a field called maximum transmit size for
TX secy. Max packet size going out of MCS block has be programmed
taking into account full packet size which has L2 header,SecTag
and ICV. MACSEC offload driver is configuring max transmit size as
macsec interface MTU which is incorrect. Say with 1500 MTU of real
device, macsec interface created on top of real device will have MTU of
1468(1500 - (SecTag + ICV)). This is causing packets from macsec
interface of size greater than or equal to 1468 are not getting
transmitted out because driver programmed max transmit size as 1468
instead of 1514(1500 + ETH_HDR_LEN).

This change enhances the robustness of validate_userspace() by ensuring
that all Netlink attributes are fully contained within the parent
attribute. The previous use of nla_parse_nested_deprecated() could
silently skip trailing or malformed attributes, as it stops parsing at
the first invalid entry.
By switching to nla_parse_deprecated_strict(), we make sure only fully
validated attributes are copied for later use.

With some Infineon chips the timeouts in tpm_tis_send_data (both B and
C) can reach up to about 2250 ms.
Timeout C is retried since
commit de9e33df7762 ("tpm, tpm_tis: Workaround failed command reception on Infineon devices")
Timeout B still needs to be extended.
The problem is most commonly encountered with context related operation
such as load context/save context. These are issued directly by the
kernel, and there is no retry logic for them.
When a filesystem is set up to use the TPM for unlocking the boot fails,
and restarting the userspace service is ineffective. This is likely
because ignoring a load context/save context result puts the real TPM
state and the TPM state expected by the kernel out of sync.
Chips known to be affected:

Description: SLB9672
Firmware Revision: 15.22

Pull tracing fixes from Steven Rostedt:
- Fix sample code that uses trace_array_printk()
The sample code for in kernel use of trace_array (that creates an
instance for use within the kernel) and shows how to use
trace_array_printk() that writes into the created instance, used
trace_printk_init_buffers(). But that function is used to initialize
normal trace_printk() and produces the NOTICE banner which is not
needed for use of trace_array_printk(). The function to initialize
that is trace_array_init_printk() that takes the created trace array
instance as a parameter.
Update the sample code to reflect the proper usage.
- Fix preemption count output for stacktrace event
The tracing buffer shows the preempt count level when an event
executes. Because writing the event itself disables preemption, this
needs to be accounted for when recording. The stacktrace event did
not account for this so the output of the stacktrace event showed
preemption was disabled while the event that triggered the stacktrace
shows preemption is enabled and this leads to confusion. Account for
preemption being disabled for the stacktrace event.
The same happened for stack traces triggered by function tracer.
- Fix persistent ring buffer when trace_pipe is used
The ring buffer swaps the reader page with the next page to read from
the write buffer when trace_pipe is used. If there's only a page of
data in the ring buffer, this swap will cause the "commit" pointer
(last data written) to be on the reader page. If more data is written
to the buffer, it is added to the reader page until it falls off back
into the write buffer.
If the system reboots and the commit pointer is still on the reader
page, even if new data was written, the persistent buffer validator
will miss finding the commit pointer because it only checks the write
buffer and does not check the reader page. This causes the validator
to fail the validation and clear the buffer, where the new data is
lost.
There was a check for this, but it checked the "head pointer", which
was incorrect, because the "head pointer" always stays on the write
buffer and is the next page to swap out for the reader page. Fix the
logic to catch this case and allow the user to still read the data
after reboot.

The ring buffer is made up of sub buffers (sometimes called pages as they
are by default PAGE_SIZE). It has the following "pages":
"tail page" - this is the page that the next write will write to
"head page" - this is the page that the reader will swap the reader page with.
"reader page" - This belongs to the reader, where it will swap the head
page from the ring buffer so that the reader does not
race with the writer.
The writer may end up on the "reader page" if the ring buffer hasn't
written more than one page, where the "tail page" and the "head page" are
the same.
The persistent ring buffer has meta data that points to where these pages
exist so on reboot it can re-create the pointers to the cpu_buffer
descriptor. But when the commit page is on the reader page, the logic is
incorrect.
The check to see if the commit page is on the reader page checked if the
head page was the reader page, which would never happen, as the head page
is always in the ring buffer. The correct check would be to test if the
commit page is on the reader page. If that's the case, then it can exit
out early as the commit page is only on the reader page when there's only
one page of data in the buffer. There's no reason to iterate the ring
buffer pages to find the "commit page" as it is already found.
To trigger this bug:
# echo 1 > /sys/kernel/tracing/instances/boot_mapped/events/syscalls/sys_enter_fchownat/enable
# touch /tmp/x
# chown sshd /tmp/x
# reboot
On boot up, the dmesg will have:
Ring buffer meta [0] is from previous boot!
Ring buffer meta [1] is from previous boot!
Ring buffer meta [2] is from previous boot!
Ring buffer meta [3] is from previous boot!
Ring buffer meta [4] commit page not found
Ring buffer meta [5] is from previous boot!
Ring buffer meta [6] is from previous boot!
Ring buffer meta [7] is from previous boot!
Where the buffer on CPU 4 had a "commit page not found" error and that
buffer is cleared and reset causing the output to be empty and the data lost.
When it works correctly, it has:
# cat /sys/kernel/tracing/instances/boot_mapped/trace_pipe

The preemption count of the stacktrace filter command to trace ksys_read
is consistently incorrect:
$ echo ksys_read:stacktrace > set_ftrace_filter
<...>-453 [004] ...1. 38.308956: <stack trace>
=> ksys_read
=> do_syscall_64
=> entry_SYSCALL_64_after_hwframe
The root cause is that the trace framework disables preemption when
invoking the filter command callback in function_trace_probe_call:
preempt_disable_notrace();
probe_ops->func(ip, parent_ip, probe_opsbe->tr, probe_ops, probe->data);
preempt_enable_notrace();
Use tracing_gen_ctx_dec() to account for the preempt_disable_notrace(),
which will output the correct preemption count:

When using the stacktrace trigger command to trace syscalls, the
preemption count was consistently reported as 1 when the system call
event itself had 0 (".").
For example:
root@ubuntu22-vm:/sys/kernel/tracing/events/syscalls/sys_enter_read
$ echo stacktrace > trigger
$ echo 1 > enable
sshd-416 [002] ..... 232.864910: sys_read(fd: a, buf: 556b1f3221d0, count: 8000)
sshd-416 [002] ...1. 232.864913: <stack trace>
=> ftrace_syscall_enter
=> syscall_trace_enter
=> do_syscall_64
=> entry_SYSCALL_64_after_hwframe
The root cause is that the trace framework disables preemption in __DO_TRACE before
invoking the trigger callback.
Use the tracing_gen_ctx_dec() that will accommodate for the increase of
the preemption count in __DO_TRACE when calling the callback. The result
is the accurate reporting of:
sshd-410 [004] ..... 210.117660: sys_read(fd: 4, buf: 559b725ba130, count: 40000)
sshd-410 [004] ..... 210.117662: <stack trace>
