Pull signature checking selftest from David Howells:
"The signature checking code, as used by module signing, kexec, etc.,
is non-FIPS compliant as there is no selftest.
For a kernel to be FIPS-compliant, signature checking would have to be
tested before being used, and the box would need to panic if it's not
available (probably reasonable as simply disabling signature checking
would prevent you from loading any driver modules).
Deal with this by adding a minimal test.
This is split into two patches: the first moves load_certificate_list()
to the same place as the X.509 code to make it more accessible
internally; the second adds a selftest"

The recent patch to make afs_getattr consult the server didn't account
for the pseudo-inodes employed by the dynamic root-type afs superblock
not having a volume or a server to access, and thus an oops occurs if
such a directory is stat'd.
Fix this by checking to see if the vnode->volume pointer actually points
anywhere before following it in afs_getattr().
This can be tested by stat'ing a directory in /afs. It may be
sufficient just to do "ls /afs" and the oops looks something like:
BUG: kernel NULL pointer dereference, address: 0000000000000020

Add some selftests for signature checking when FIPS mode is enabled. These
need to be done before we start actually using the signature checking for
things and must panic the kernel upon failure.
Note that the tests must not check the blacklist lest this provide a way to
prevent a kernel from booting by installing a hash of a test key in the
appropriate UEFI table.

Move load_certificate_list(), which loads a series of binary X.509
certificates from a blob and inserts them as keys into a keyring, to be
with the asymmetric keys code that it drives.
This makes it easier to add FIPS selftest code in which we need to load up
a private keyring for the tests to use.

Except for memory load and store operations, ARM SPE records also can
support other operation types, bug when set the data source field the
current code assumes a record is a either load operation or store
operation, this leads to wrongly synthesize memory samples.
This patch strictly checks the record operation type, it only sets data
source only for the operation types ARM_SPE_LD and ARM_SPE_ST,
otherwise, returns zero for data source. Therefore, we can synthesize
memory samples only when data source is a non-zero value, the function
arm_spe__is_memory_event() is useless and removed.

If perf_event_open() fails the fd is opened but it is only freed by
closing (not by delete).
Typically when an open fails you don't call close and so this results in
a memory leak. To avoid this, add a close when open fails.

perf test -F 83 ("perf stat CSV output linter") fails on s390.
Reason is the wrong number of fields for certain CPU core/die/socket
related output.
On x84_64 the output of command:
# ./perf stat -x, -A -a --no-merge true
CPU0,1.50,msec,cpu-clock,1502781,100.00,1.052,CPUs utilized
CPU1,1.48,msec,cpu-clock,1476113,100.00,1.034,CPUs utilized
...
results in 8 fields with 7 comma separators.
On s390 the output of command:
# ./perf stat -x, -A -a --no-merge -- true
0.95,msec,cpu-clock,949800,100.00,1.060,CPUs utilized
...
results in 7 fields with 6 comma separators. Therefore this tests
fails on s390. Similar issues exist for per-die and per-socket output
which is not supported on s390.
I have rewritten the python program to count commas in each output line
into a bash function to achieve the same result. I hope this makes it a
bit easier.

We capture a NULL pointer issue when resizing a corrupt ext4 image which
is freshly clear resize_inode feature (not run e2fsck). It could be
simply reproduced by following steps. The problem is because of the
resize_inode feature was cleared, and it will convert the filesystem to
meta_bg mode in ext4_resize_fs(), but the es->s_reserved_gdt_blocks was
not reduced to zero, so could we mistakenly call reserve_backup_gdb()

ext4_mb_normalize_request() can move logical start of allocated blocks
to reduce fragmentation and better utilize preallocation. However logical
block requested as a start of allocation (ac->ac_o_ex.fe_logical) should
always be covered by allocated blocks so we should check that by
modifying and to or in the assertion.

`mkfs.ext4 -b 1024 -g 256 disk`
`mount disk /mnt`
`fsstress -d /mnt -l 0 -n 1000 -p 1`
The size must be smaller than or equal to EXT4_BLOCKS_PER_GROUP.
Therefore, "start + size <= ac->ac_o_ex.fe_logical" may occur
when the size is truncated. So start should be the start position of
the group where ac_o_ex.fe_logical is located after alignment.
In addition, when the value of fe_logical or EXT4_BLOCKS_PER_GROUP
is very large, the value calculated by start_off is more accurate.

Since ext4 was converted to the new mount API, the test_dummy_encryption
mount option isn't being handled entirely correctly, because the needed
fscrypt_set_test_dummy_encryption() helper function combines
parsing/checking/applying into one function. That doesn't work well
with the new mount API, which split these into separate steps.
This was sort of okay anyway, due to the parsing logic that was copied
from fscrypt_set_test_dummy_encryption() into ext4_parse_param(),
combined with an additional check in ext4_check_test_dummy_encryption().
However, these overlooked the case of changing the value of
test_dummy_encryption on remount, which isn't allowed but ext4 wasn't
detecting until ext4_apply_options() when it's too late to fail.
Another bug is that if test_dummy_encryption was specified multiple
times with an argument, memory was leaked.
Fix this up properly by using the new helper functions that allow
splitting up the parse/check/apply steps for test_dummy_encryption.

load_unaligned_zeropad() can lead to unwanted loads across page boundaries.
The unwanted loads are typically harmless. But, they might be made to
totally unrelated or even unmapped memory. load_unaligned_zeropad()
relies on exception fixup (#PF, #GP and now #VE) to recover from these
unwanted loads.
In TDX guests, the second page can be shared page and a VMM may configure
it to trigger #VE.
The kernel assumes that #VE on a shared page is an MMIO access and tries to
decode instruction to handle it. In case of load_unaligned_zeropad() it
may result in confusion as it is not MMIO access.
Fix it by detecting split page MMIO accesses and failing them.
load_unaligned_zeropad() will recover using exception fixups.
The issue was discovered by analysis and reproduced artificially. It was
not triggered during testing.

printk: Wait for the global console lock when the system is going down

This reverts commit 4c5e242d3e.
Prior to 4c5e242d3e ("x86/PCI: Clip only host bridge windows for E820
regions"), E820 regions did not affect PCI host bridge windows. We only
looked at E820 regions and avoided them when allocating new MMIO space.
If firmware PCI bridge window and BAR assignments used E820 regions, we
left them alone.
After 4c5e242d3e, we removed E820 regions from the PCI host bridge
windows before looking at BARs, so firmware assignments in E820 regions
looked like errors, and we moved things around to fit in the space left
(if any) after removing the E820 regions. This unnecessary BAR
reassignment broke several machines.
Guilherme reported that Steam Deck fails to boot after 4c5e242d3e. We
clipped the window that contained most 32-bit BARs:
BIOS-e820: [mem 0x00000000a0000000-0x00000000a00fffff] reserved
acpi PNP0A08:00: clipped [mem 0x80000000-0xf7ffffff window] to [mem 0xa0100000-0xf7ffffff window] for e820 entry [mem 0xa0000000-0xa00fffff]
which forced us to reassign all those BARs, for example, this NVMe BAR:
pci 0000:00:01.2: PCI bridge to [bus 01]
pci 0000:00:01.2: bridge window [mem 0x80600000-0x806fffff]
pci 0000:01:00.0: BAR 0: [mem 0x80600000-0x80603fff 64bit]
pci 0000:00:01.2: can't claim window [mem 0x80600000-0x806fffff]: no compatible bridge window
pci 0000:01:00.0: can't claim BAR 0 [mem 0x80600000-0x80603fff 64bit]: no compatible bridge window
pci 0000:00:01.2: bridge window: assigned [mem 0xa0100000-0xa01fffff]
pci 0000:01:00.0: BAR 0: assigned [mem 0xa0100000-0xa0103fff 64bit]
All the reassignments were successful, so the devices should have been
functional at the new addresses, but some were not.
Andy reported a similar failure on an Intel MID platform. Benjamin
reported a similar failure on a VMWare Fusion VM.
Note: this is not a clean revert; this revert keeps the later change to
make the clipping dependent on a new pci_use_e820 bool, moving the checking
of this bool to arch_remove_reservations().
