Add __GFP_ZERO flag for compose_sadb_supported in function pfkey_register
to initialize the buffer of supp_skb to fix a kernel-info-leak issue.
1) Function pfkey_register calls compose_sadb_supported to request
a sk_buff. 2) compose_sadb_supported calls alloc_sbk to allocate
a sk_buff, but it doesn't zero it. 3) If auth_len is greater 0, then
compose_sadb_supported treats the memory as a struct sadb_supported and
begins to initialize. But it just initializes the field sadb_supported_len
and field sadb_supported_exttype without field sadb_supported_reserved.

This series updates the Microchip Icicle Kit device tree by adding a
host of peripherals, and some updates to the memory map. In addition,
the device tree has been split into a third part, which contains "soft"
peripherals that are in the fpga fabric.
Several of the entries are for peripherals that have not get had their
drivers upstreamed, so in those cases the dt bindings are included where
appropriate in order to avoid the many "DT compatible string <x> appears
un-documented" errors.

Pull xen fixes from Juergen Gross:
"Several Linux PV device frontends are using the grant table interfaces
for removing access rights of the backends in ways being subject to
race conditions, resulting in potential data leaks, data corruption by
malicious backends, and denial of service triggered by malicious
backends:
- blkfront, netfront, scsifront and the gntalloc driver are testing
whether a grant reference is still in use. If this is not the case,
they assume that a following removal of the granted access will
always succeed, which is not true in case the backend has mapped
the granted page between those two operations.
As a result the backend can keep access to the memory page of the
guest no matter how the page will be used after the frontend I/O
has finished. The xenbus driver has a similar problem, as it
doesn't check the success of removing the granted access of a
shared ring buffer.
- blkfront, netfront, scsifront, usbfront, dmabuf, xenbus, 9p,
kbdfront, and pvcalls are using a functionality to delay freeing a
grant reference until it is no longer in use, but the freeing of
the related data page is not synchronized with dropping the granted
access.
As a result the backend can keep access to the memory page even
after it has been freed and then re-used for a different purpose.
- netfront will fail a BUG_ON() assertion if it fails to revoke
access in the rx path.
This will result in a Denial of Service (DoS) situation of the
guest which can be triggered by the backend"

When using "run_cmd <command> &", then "$!" refers to the PID of the
subshell used to run <command>, not the command itself. Therefore
nettest_pids actually doesn't contain the list of the nettest commands
running in the background. So cleanup() can't kill them and the nettest
processes run until completion (fortunately they have a 5s timeout).
Fix this by defining a new command for running processes in the
background, for which "$!" really refers to the PID of the command run.
Also, double quote variables on the modified lines, to avoid shellcheck
warnings.

The cleanup() function takes care of killing processes launched by the
test functions. It relies on variables like ${tcpdump_pids} to get the
relevant PIDs. But tests are run in their own subshell, so updated
*_pids values are invisible to other shells. Therefore cleanup() never
sees any process to kill:

6235 tcpdump -s 0 -i veth_B-R2 -w pmtu_ipv4_exception_veth_B-R2.pcap
Fix this by running cleanup() in the context of the test subshell.
Now that each test cleans the environment after completion, there's no
need for calling cleanup() again when the next test starts. So let's
drop it from the setup() function. This is okay because cleanup() is
also called when pmtu.sh starts, so even the first test starts in a
clean environment.
Also, use tcpdump's immediate mode. Otherwise it might not have time to
process buffered packets, resulting in missing packets or even empty
pcap files for short tests.
Note: PAUSE_ON_FAIL is still evaluated before cleanup(), so one can
still inspect the test environment upon failure when using -p.

Back when tcp_tso_autosize() and TCP pacing were introduced,
our focus was really to reduce burst sizes for long distance
flows.
The simple heuristic of using sk_pacing_rate/1024 has worked
well, but can lead to too small packets for hosts in the same
rack/cluster, when thousands of flows compete for the bottleneck.
Neal Cardwell had the idea of making the TSO burst size
a function of both sk_pacing_rate and tcp_min_rtt()
Indeed, for local flows, sending bigger bursts is better
to reduce cpu costs, as occasional losses can be repaired
quite fast.
This patch is based on Neal Cardwell implementation
done more than two years ago.
bbr is adjusting max_pacing_rate based on measured bandwidth,
while cubic would over estimate max_pacing_rate.
/proc/sys/net/ipv4/tcp_tso_rtt_log can be used to tune or disable
this new feature, in logarithmic steps.
Tested:
100Gbit NIC, two hosts in the same rack, 4K MTU.
600 flows rate-limited to 20000000 bytes per second.
Before patch: (TSO sizes would be limited to 20000000/1024/4096 -> 4 segments per TSO)

tcp_should_autocork() is evaluating if it makes senses
to not immediately send current skb, hoping that
user space will add more payload on it by the
time TCP stack reacts to upcoming TX completions.
If current skb got MSG_EOR mark, then we know
that no further data will be added, it is therefore
futile to wait.
SOF_TIMESTAMPING_TX_ACK will become a bit more accurate,
if prior packets are still in qdisc/device queues.

Dimitris Michailidis says:
====================
net/fungible: fix errors when CONFIG_TLS_DEVICE=n
This pair of patches fix compile errors in funeth when
CONFIG_TLS_DEVICE=n. The errors are due to symbols that are not defined
in this config but are used in code guarded by
"if (IS_ENABLED(CONFIG_TLS_DEVICE) ..."
One option is to place this code under preprocessor guards that will
keep the compiler from looking at the code. The option adopted here is
to define the offending symbols also when CONFIG_TLS_DEVICE=n.
The first patch does this for two functions in tls.h.
The second does the same for driver symbols and makes tls.h inclusion

Having the definitions of {__,}tls_driver_ctx() under an #if
guard means code referencing them also needs to rely on the

Syzbot reported UAF in port100_send_complete(). The root case is in
missing usb_kill_urb() calls on error handling path of ->probe function.
port100_send_complete() accesses devm allocated memory which will be
freed on probe failure. We should kill this urbs before returning an
error from probe function to prevent reported use-after-free

There is occasional suspend error from e1000e which blocks the
system from further suspending. And the issue was found on
a WhiskeyLake-U platform with I219-V:
[ 20.078957] PM: pci_pm_suspend(): e1000e_pm_suspend+0x0/0x780 [e1000e] returns -2
[ 20.078970] PM: dpm_run_callback(): pci_pm_suspend+0x0/0x170 returns -2
[ 20.078974] e1000e 0000:00:1f.6: PM: pci_pm_suspend+0x0/0x170 returned -2 after 371012 usecs
[ 20.078978] e1000e 0000:00:1f.6: PM: failed to suspend async: error -2
According to the code flow, this might be caused by broken MDI read/write
to PHY registers. However currently the code does not tell us which
register is broken. Thus enhance the debug information to print the
offender PHY register. So the next the issue is reproduced, this
information could be used for narrow down.

This chips supports two ways to configure max MTU size:
- by setting SW_LEGAL_PACKET_DISABLE bit: if this bit is 0 allowed packed size
will be between 64 and bytes 1518. If this bit is 1, it will accept
packets up to 2000 bytes.
- by setting SW_JUMBO_PACKET bit. If this bit is set, the chip will
ignore SW_LEGAL_PACKET_DISABLE value and use REG_SW_MTU__2 register to
configure MTU size.
Current driver has disabled SW_JUMBO_PACKET bit and activates
SW_LEGAL_PACKET_DISABLE. So the switch will pass all packets up to 2000 without
any way to configure it.
By providing port_change_mtu we are switch to SW_JUMBO_PACKET way and will
be able to configure MTU up to ~9000.

platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue
when using hierarchical interrupt domains using "interrupts" property
in the node as this bypasses the hierarchical setup and messes up the
irq chaining.
In preparation for removal of static setup of IRQ resource from DT core
code use platform_get_irq().

Performance monitoring support for papr-scm nvdimm devices
via perf interface is added which includes addition of pmu
functions like add/del/read/event_init for nvdimm_pmu struture.
A new parameter 'priv' in added to the pdev_archdata structure to save
nvdimm_pmu device pointer, to handle the unregistering of pmu device.
papr_scm_pmu_register function populates the nvdimm_pmu structure
with name, capabilities, cpumask along with event handling
functions. Finally the populated nvdimm_pmu structure is passed to
register the pmu device. Event handling functions internally uses
hcall to get events and counter data.
Result in power9 machine with 2 nvdimm device:

A common interface is added to get performance stats reporting
support for nvdimm devices. Added interface defines supported
event list, config fields for the event attributes and their
corresponding bit values which are exported via sysfs.
Interface also added support for pmu register/unregister functions,
cpu hotplug feature along with macros for handling events addition
via sysfs. It adds attribute groups for format, cpumask and events
to the pmu structure.
User could use the standard perf tool to access perf events exposed
via nvdimm pmu.
