Pull KVM fixes from Paolo Bonzini:
"ARM:
- Avoid use of uninitialized memcache pointer in user_mem_abort()
- Always set HCR_EL2.xMO bits when running in VHE, allowing
interrupts to be taken while TGE=0 and fixing an ugly bug on
AmpereOne that occurs when taking an interrupt while clearing the
xMO bits (AC03_CPU_36)
- Prevent VMMs from hiding support for AArch64 at any EL virtualized
by KVM
- Save/restore the host value for HCRX_EL2 instead of restoring an
incorrect fixed value
- Make host_stage2_set_owner_locked() check that the entire requested
range is memory rather than just the first page
RISC-V:
- Add missing reset of smstateen CSRs
x86:
- Forcibly leave SMM on SHUTDOWN interception on AMD CPUs to avoid
causing problems due to KVM stuffing INIT on SHUTDOWN (KVM needs to
sanitize the VMCB as its state is undefined after SHUTDOWN,
emulating INIT is the least awful choice).
- Track the valid sync/dirty fields in kvm_run as a u64 to ensure KVM
KVM doesn't goof a sanity check in the future.
- Free obsolete roots when (re)loading the MMU to fix a bug where
pre-faulting memory can get stuck due to always encountering a
stale root.
- When dumping GHCB state, use KVM's snapshot instead of the raw GHCB
page to print state, so that KVM doesn't print stale/wrong
information.
- When changing memory attributes (e.g. shared <=> private), add
potential hugepage ranges to the mmu_invalidate_range_{start,end}
set so that KVM doesn't create a shared/private hugepage when the
the corresponding attributes will become mixed (the attributes are
commited *after* KVM finishes the invalidation).
- Rework the SRSO mitigation to enable BP_SPEC_REDUCE only when KVM
has at least one active VM. Effectively BP_SPEC_REDUCE when KVM is
loaded led to very measurable performance regressions for non-KVM
workloads"

The compiler is unaware of the size of code generated by the ".rept"
assembler directive. This results in the compiler emitting branch
instructions where the offset to branch to exceeds the maximum allowed
value, resulting in build failures like the following:
CC protection_keys

/tmp/ccypKWAE.s:2073: Error: operand out of range (0x0000000000020158

Commit 50910acd6f615 ("selftests/mm: use sys_pkey helpers consistently")
added a pkey_util.c to refactor some of the protection_keys functions
accessible by other tests. But this broken the build in powerpc in two
ways,
pkey-powerpc.h: In function `arch_is_powervm':
pkey-powerpc.h:73:21: error: storage size of `buf' isn't known
73 | struct stat buf;
| ^~~
pkey-powerpc.h:75:14: error: implicit declaration of function `stat'; did you mean `strcat'? [-Wimplicit-function-declaration]
75 | if ((stat("/sys/firmware/devicetree/base/ibm,partition-name", &buf) == 0) &&
| ^~~~
| strcat
Since pkey_util.c includes pkeys-helper.h, which in turn includes pkeys-powerpc.h,
stat.h including is missing for "struct stat". This is fixed by adding "sys/stat.h"
in pkeys-powerpc.h
Secondly,
pkey-powerpc.h:55:18: warning: format `%llx' expects argument of type `long long unsigned int', but argument 3 has type `u64' {aka `long unsigned int'} [-Wformat=]
55 | dprintf4("%s() changing %016llx to %016llx\n",
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
56 | __func__, __read_pkey_reg(), pkey_reg);

| |
| u64 {aka long unsigned int}
pkey-helpers.h:63:32: note: in definition of macro `dprintf_level'
63 | sigsafe_printf(args); \
| ^~~~
These format specifier related warning are removed by adding
"__SANE_USERSPACE_TYPES__" to pkeys_utils.c.

The current implementation of the guard region tests assume that /tmp is
mounted as tmpfs, that is shmem.
This isn't always the case, and at least one instance of a spurious test
failure has been reported as a result.
This assumption is unsafe, rushed and silly - and easily remedied by
simply using memfd, so do so.
We also have to fixup the readonly_file test to explicitly only be
applicable to file-backed cases.

When running mm selftest to verify mm patches, 'compaction_test' case
failed on an x86 server with 1TB memory. And the root cause is that it
has too much free memory than what the test supports.
The test case tries to allocate 100000 huge pages, which is about 200 GB
for that x86 server, and when it succeeds, it expects it's large than 1/3
of 80% of the free memory in system. This logic only works for platform
with 750 GB ( 200 / (1/3) / 80% ) or less free memory, and may raise false
alarm for others.
Fix it by changing the fixed page number to self-adjustable number
according to the real number of free memory.

Starting with Rust 1.87.0 (expected 2025-05-15), `objtool` may report:
rust/core.o: warning: objtool: _R..._4core9panicking9panic_fmt() falls
through to next function _R..._4core9panicking18panic_nounwind_fmt()
rust/core.o: warning: objtool: _R..._4core9panicking18panic_nounwind_fmt()
falls through to next function _R..._4core9panicking5panic()
The reason is that `rust_begin_unwind` is now mangled:
_R..._7___rustc17rust_begin_unwind
Thus add the mangled one to the list so that `objtool` knows it is
actually `noreturn`.
See commit 56d680dd23c3 ("objtool/rust: list `noreturn` Rust functions")
for more details.
Alternatively, we could remove the fixed one in `noreturn.h` and relax
this test to cover both, but it seems best to be strict as long as we can.

Strings from the kernel are guaranteed to be null terminated and

GRE devices have their special code for IPv6 link-local address
generation that has been the source of several regressions in the past.
Add selftest to check that all gre, ip6gre, gretap and ip6gretap get an
IPv6 link-link local address in accordance with the
net.ipv6.conf.<dev>.addr_gen_mode sysctl.
Note: This patch was originally applied as commit 6f50175ccad4 ("selftests:
Add IPv6 link-local address generation tests for GRE devices.").
However, it was then reverted by commit 355d940f4d5a ("Revert "selftests:
Add IPv6 link-local address generation tests for GRE devices."")
because the commit it depended on was going to be reverted. Now that
the situation is resolved, we can add this selftest again (no changes
since original patch, appart from context update in
tools/testing/selftests/net/Makefile).

Merge series from Olivier Moysan <olivier.moysan@foss.st.com>:
This patchset adds some checks on kernel minimum rate requirements.
This avoids potential clock rate misconfiguration, when setting the
kernel frequency on STM32MP2 SoCs.
|
|
Add a forwarding path test for tc-taprio, based on isochron. This is
specifically intended for NICs with an offloaded data path (switchdev/DSA)
and requires taprio 'flags 2'. Also, $h1 and $h2 must support hardware
timestamping, and $h1 tc-etf offload, for isochron to work.
Packets received by a switch while the egress port has a taprio schedule
with an open gate for the traffic class must be sent right away.
Packets received by the switch while the traffic class gate must be
delayed until it opens.
Packets received by the switch must be dropped if the gate for the
traffic class never opens.
Packets should pass if the maximum SDU for the traffic class allows it,
and should be dropped otherwise.
The schedule should auto-update itself if clock jumps take place while
taprio is installed. Repeat most of the above tests after forcing two
clock jumps, one backwards (in Jan 1970) and one back into the present.
Symlink it from tools/testing/selftests/drivers/net/dsa, because usually
DSA ports have the same MAC address, and we need STABLE_MAC_ADDRS=yes
from its forwarding.config for the test to run successfully.

Make out-of-band testing (send a packet when its traffic class gate is
closed, expecting it to be delayed) more predictable by allowing the
window size to be customized by isochron_do().
From man isochron-send, the window size alters the advance time (the
delta between the transmission time of the packet, and its expected TX
time when using SO_TXTIME or tc-taprio on the sender). In absence of the
argument, isochron-send defaults to maximizing the advance time (making
it equal to the cycle length).
The default behavior is exactly what is problematic. An advance time
that is too large will make packets intended to be out-of-band still be
potentially in-band with an open gate from the schedule's previous cycle.
We need to allow that advance time to be reduced.
Perhaps a bit confusingly, isochron_do() has a shift_time argument
currently, but that does not help here. The shift time shifts both the
user space wakeup time and the expected TX time by equal amounts, it is
unable of bringing them closer to one another.
Set the window size properly for the Ocelot PSFP selftest as well.
That used to work due to a very carefully chosen SHIFT_TIME_NS.
I've re-tested that the test still works properly.

When libperf is built alone in-source, $(OUTPUT) isn't set. This causes
the generated uapi path to resolve to '/../arch' which results in a
permissions error:
mkdir: cannot create directory '/../arch': Permission denied
Fix it by removing the preceding '/..' which means that it gets
generated either in the tools/lib/perf part of the tree or the OUTPUT
folder. Some other rules that rely on OUTPUT further refine this
conditionally depending on whether it's an in-source or out-of-source
build, but I don't think we need the extra complexity here. And this
rule is slightly different to others because the header is needed by
both libperf and Perf. This is further complicated by the fact that Perf
always passes O=... to libperf even for in source builds, meaning that
OUTPUT isn't set consistently between projects.
Because we're no longer going one level up to try to generate the file
in the tools/ folder, Perf's include rule needs to descend into libperf.
Also fix the clean rule while we're here.

without PVID
Recent discussions around commit ad1afb003939 ("vlan_dev: VLAN 0 should
be treated as "no vlan tag" (802.1p packet)") have sparked the question
what happens with the DSA (and possibly other switchdev) data path when
the bridge says that ports should have no PVID VLAN, but the 8021q
module, as the result of a NETDEV_UP event, decides it should add VID 0
to the RX filter of those bridge ports. Do those bridge ports receive
packets tagged with VID 0 or not, now? We don't know, there is no test.
In the veth realm, this passes trivially, because veth is not VLAN
filtering and this, the 8021q module lacks the instinct to add VID 0 in
the first place.
In the realm of VLAN filtering NICs with no switchdev offload, this
should also pass, because the VLAN groups of the software bridge are
consulted, where it can clearly be seen that a PVID is missing, even
though the packet was initially accepted by the NIC.
The test only poses a challenge for switchdev drivers, which usually
have to program to hardware both VLANs from RX filtering, as well as
from switchdev. Especially when a switchdev port joins a VLAN-aware
bridge, it is unavoidable that it gains the NETIF_F_HW_VLAN_CTAG_FILTER
feature, i.e. any 8021q uppers that the bridge port may have must also
be committed to the RX filtering table of the interface. When a
VLAN-tagged packet is physically received by the port, it is initially
indistinguishable whether it will reach the bridge data path or the
8021q upper data path.
That is rather the final step of the new tests that we introduce.
We need to build context up to that stage, which means the following:
- we need to test that 802.1p (VID 0) tagged traffic is received in the
first place (on bridge ports with a valid PVID). This is the "8021p"
test.
- we need to test that the usual paths of reaching a configuration with
no PVID on a bridge port are all covered and they all reach the same
state.

After recent changes in the VM network stack, the host fails to
display the IP addresses of the VM. As a result the "IP Addresses"
column in the "Networking" tab in the Windows Hyper-V Manager is
empty. This is caused by a change in the expected output of the
"ip route show" command. Previously the gateway address was shown
in the third row. Now the gateway addresses might be split into
several lines of output. As a result, the string "ra" instead of
an IP address is sent to the host.
To me more specific, a VM with the wellknown wicked network
managing tool still shows the expected output in recent openSUSE
Tumbleweed snapshots:

Some distributions, such as centos stream 9, still have a version of
coreutils which does not yet support the %Hr and %Lr formats for stat(1)
[1, 2]. Running ublk selftests on these distributions results in the
following error in tests that use the _get_disk_dev_t helper:
line 23: ?r: syntax error: operand expected (error token is "?r")
To better accommodate older distributions, rewrite _get_disk_dev_t to
use the much older %t and %T formats for stat instead.

Add a selftest to exercise the condition where qdisc implementations
like netem or codel might empty the queue during a peek operation.
This tests the defensive code path in HFSC that checks the queue length
again after peeking to handle this case.
Based on the reproducer from Gerrard, improved by Jamal.

When running diag.sh in a loop, chk_dump_one will report the following
"grep: write error":
13 ....chk 2 cestab [ OK ]
grep: write error
14 ....chk dump_one [ OK ]
15 ....chk 2->0 msk in use after flush [ OK ]
16 ....chk 2->0 cestab after flush [ OK ]
This error is caused by a broken pipe. When the output of 'ss' is processed
by grep, 'head -n 1' will exit immediately after getting the first line,
causing the subsequent pipe to close. At this time, if 'grep' is still
trying to write data to the closed pipe, it will trigger a SIGPIPE signal,
causing a write error.
One solution is not to use this problematic "head -n 1" command, but to use
mptcp_lib_get_info_value() helper defined in mptcp_lib.sh to get the value
of 'token'.

'delay_us' shouldn't be added to 'struct dev_ctx' since now it is
handled by per-target command line & 'struct fault_inject_ctx'.
So remove it.
