arm64: signal: Remove unnecessary check when saving POE state
The POE frame record is allocated unconditionally if POE is supported. If the allocation fails, a SIGSEGV is delivered before setup_sigframe() can be reached. As a result there is no need to consider poe_offset before saving POR_EL0; just remove that check. This is in line with other frame records (FPMR, TPIDR2).

arm64: signal: Improve POR_EL0 handling to avoid uaccess failures
Reset POR_EL0 to "allow all" before writing the signal frame, preventing
spurious uaccess failures.
When POE is supported, the POR_EL0 register constrains memory
accesses based on the target page's POIndex (pkey). This raises the
question: what constraints should apply to a signal handler? The
current answer is that POR_EL0 is reset to POR_EL0_INIT when
invoking the handler, giving it full access to POIndex 0. This is in
line with x86's MPK support and remains unchanged.
This is only part of the story, though. POR_EL0 constrains all
unprivileged memory accesses, meaning that uaccess routines such as
put_user() are also impacted. As a result POR_EL0 may prevent the
signal frame from being written to the signal stack (ultimately
causing a SIGSEGV). This is especially concerning when an alternate
signal stack is used, because userspace may want to prevent access
to it outside of signal handlers. There is currently no provision
for that: POR_EL0 is reset after writing to the stack, and
POR_EL0_INIT only enables access to POIndex 0.
This patch ensures that POR_EL0 is reset to its most permissive
state before the signal stack is accessed. Once the signal frame has
been fully written, POR_EL0 is still set to POR_EL0_INIT - it is up
to the signal handler to enable access to additional pkeys if
needed. As to sigreturn(), it expects having access to the stack
like any other syscall; we only need to ensure that POR_EL0 is
restored from the signal frame after all uaccess calls. This
approach is in line with the recent x86/pkeys series [1].
Resetting POR_EL0 early introduces some complications, in that we
can no longer read the register directly in preserve_poe_context().
This is addressed by introducing a struct (user_access_state)
and helpers to manage any such register impacting user accesses
(uaccess and accesses in userspace). Things look like this on signal
delivery:
1. Save original POR_EL0 into struct [save_reset_user_access_state()]
2. Set POR_EL0 to "allow all" [save_reset_user_access_state()]
3. Create signal frame
4. Write saved POR_EL0 value to the signal frame [preserve_poe_context()]
5. Finalise signal frame
6. If all operations succeeded:
a. Set POR_EL0 to POR_EL0_INIT [set_handler_user_access_state()]
b. Else reset POR_EL0 to its original value [restore_user_access_state()]
If any step fails when setting up the signal frame, the process will
be sent a SIGSEGV, which it may be able to handle. Step 6.b ensures
that the original POR_EL0 is saved in the signal frame when
delivering that SIGSEGV (so that the original value is restored by
sigreturn).
The return path (sys_rt_sigreturn) doesn't strictly require any change
since restore_poe_context() is already called last. However, to
avoid uaccess calls being accidentally added after that point, we
use the same approach as in the delivery path, i.e. separating
uaccess from writing to the register:
1. Read saved POR_EL0 value from the signal frame [restore_poe_context()]
2. Set POR_EL0 to the saved value [restore_user_access_state()]

kasan: Fix Software Tag-Based KASAN with GCC
Per [1], -fsanitize=kernel-hwaddress with GCC currently does not disable
instrumentation in functions with __attribute__((no_sanitize_address)).
However, __attribute__((no_sanitize("hwaddress"))) does correctly
disable instrumentation. Use it instead.

arm64: probes: Fix uprobes for big-endian kernels
The arm64 uprobes code is broken for big-endian kernels as it doesn't
convert the in-memory instruction encoding (which is always
little-endian) into the kernel's native endianness before analyzing and
simulating instructions. This may result in a few distinct problems:
* The kernel may may erroneously reject probing an instruction which can
safely be probed.
* The kernel may erroneously erroneously permit stepping an
instruction out-of-line when that instruction cannot be stepped
out-of-line safely.
* The kernel may erroneously simulate instruction incorrectly dur to
interpretting the byte-swapped encoding.
The endianness mismatch isn't caught by the compiler or sparse because:
* The arch_uprobe::{insn,ixol} fields are encoded as arrays of u8, so
the compiler and sparse have no idea these contain a little-endian
32-bit value. The core uprobes code populates these with a memcpy()
which similarly does not handle endianness.
* While the uprobe_opcode_t type is an alias for __le32, both
arch_uprobe_analyze_insn() and arch_uprobe_skip_sstep() cast from u8[]
to the similarly-named probe_opcode_t, which is an alias for u32.
Hence there is no endianness conversion warning.
Fix this by changing the arch_uprobe::{insn,ixol} fields to __le32 and
adding the appropriate __le32_to_cpu() conversions prior to consuming
the instruction encoding. The core uprobes copies these fields as opaque
ranges of bytes, and so is unaffected by this change.
At the same time, remove MAX_UINSN_BYTES and consistently use
AARCH64_INSN_SIZE for clarity.
Tested with the following:
| #include <stdio.h>
| #include <stdbool.h>
|
| #define noinline __attribute__((noinline))
|
| static noinline void *adrp_self(void)
| {
| void *addr;
|
| asm volatile(
| " adrp %x0, adrp_self\n"
| " add %x0, %x0, :lo12:adrp_self\n"
| : "=r" (addr));
| }
|
|
| int main(int argc, char *argv)
| {
| void *ptr = adrp_self();
| bool equal = (ptr == adrp_self);
|
| printf("adrp_self => %p\n"
| "adrp_self() => %p\n"
| "%s\n",
| adrp_self, ptr, equal ? "EQUAL" : "NOT EQUAL");
|
| return 0;
| }
.... where the adrp_self() function was compiled to:
| 00000000004007e0 <adrp_self>:
| 4007e0: 90000000 adrp x0, 400000 <__ehdr_start>
| 4007e4: 911f8000 add x0, x0, #0x7e0
| 4007e8: d65f03c0 ret
Before this patch, the ADRP is not recognized, and is assumed to be
steppable, resulting in corruption of the result:
| # ./adrp-self
| adrp_self => 0x4007e0
| adrp_self() => 0x4007e0
| EQUAL
| # echo 'p /root/adrp-self:0x007e0' > /sys/kernel/tracing/uprobe_events
| # echo 1 > /sys/kernel/tracing/events/uprobes/enable
| # ./adrp-self
| adrp_self => 0x4007e0
| adrp_self() => 0xffffffffff7e0
| NOT EQUAL
After this patch, the ADRP is correctly recognized and simulated:
| # ./adrp-self
| adrp_self => 0x4007e0
| adrp_self() => 0x4007e0
| EQUAL
| #
| # echo 'p /root/adrp-self:0x007e0' > /sys/kernel/tracing/uprobe_events
| # echo 1 > /sys/kernel/tracing/events/uprobes/enable
| # ./adrp-self
| adrp_self => 0x4007e0
| adrp_self() => 0x4007e0

arm64: probes: Fix simulate_ldr*_literal()
The simulate_ldr_literal() code always loads a 64-bit quantity, and when
simulating a 32-bit load into a 'W' register, it discards the most
significant 32 bits. For big-endian kernels this means that the relevant
bits are discarded, and the value returned is the the subsequent 32 bits
in memory (i.e. the value at addr + 4).
Additionally, simulate_ldr_literal() and simulate_ldrsw_literal() use a
plain C load, which the compiler may tear or elide (e.g. if the target
is the zero register). Today this doesn't happen to matter, but it may
matter in future if trampoline code uses a LDR (literal) or LDRSW
(literal).
Update simulate_ldr_literal() and simulate_ldrsw_literal() to use an
appropriately-sized READ_ONCE() to perform the access, which avoids
these problems.

arm64: probes: Remove broken LDR (literal) uprobe support
The simulate_ldr_literal() and simulate_ldrsw_literal() functions are
unsafe to use for uprobes. Both functions were originally written for
use with kprobes, and access memory with plain C accesses. When uprobes
was added, these were reused unmodified even though they cannot safely
access user memory.
There are three key problems:
1) The plain C accesses do not have corresponding extable entries, and
thus if they encounter a fault the kernel will treat these as
unintentional accesses to user memory, resulting in a BUG() which
will kill the kernel thread, and likely lead to further issues (e.g.
lockup or panic()).
2) The plain C accesses are subject to HW PAN and SW PAN, and so when
either is in use, any attempt to simulate an access to user memory
will fault. Thus neither simulate_ldr_literal() nor
simulate_ldrsw_literal() can do anything useful when simulating a
user instruction on any system with HW PAN or SW PAN.
3) The plain C accesses are privileged, as they run in kernel context,
and in practice can access a small range of kernel virtual addresses.
The instructions they simulate have a range of +/-1MiB, and since the
simulated instructions must itself be a user instructions in the
TTBR0 address range, these can address the final 1MiB of the TTBR1
acddress range by wrapping downwards from an address in the first
1MiB of the TTBR0 address range.
In contemporary kernels the last 8MiB of TTBR1 address range is
reserved, and accesses to this will always fault, meaning this is no
worse than (1).
Historically, it was theoretically possible for the linear map or
vmemmap to spill into the final 8MiB of the TTBR1 address range, but
in practice this is extremely unlikely to occur as this would
require either:
* Having enough physical memory to fill the entire linear map all the
way to the final 1MiB of the TTBR1 address range.
* Getting unlucky with KASLR randomization of the linear map such
that the populated region happens to overlap with the last 1MiB of
the TTBR address range.
... and in either case if we were to spill into the final page there
would be larger problems as the final page would alias with error
pointers.
Practically speaking, (1) and (2) are the big issues. Given there have
been no reports of problems since the broken code was introduced, it
appears that no-one is relying on probing these instructions with
uprobes.
Avoid these issues by not allowing uprobes on LDR (literal) and LDRSW
(literal), limiting the use of simulate_ldr_literal() and
simulate_ldrsw_literal() to kprobes. Attempts to place uprobes on LDR
(literal) and LDRSW (literal) will be rejected as
arm_probe_decode_insn() will return INSN_REJECTED. In future we can
consider introducing working uprobes support for these instructions, but
this will require more significant work.

arm64: Force position-independent veneers
Certain portions of code always need to be position-independent regardless of CONFIG_RELOCATABLE, including code which is executed in an idmap or which is executed before relocations are applied. In some kernel configurations the LLD linker generates position-dependent veneers for such code, and when executed these result in early boot-time failures. Marc Zyngier encountered a boot failure resulting from this when building a (particularly cursed) configuration with LLVM, as he reported to the list: https://lore.kernel.org/linux-arm-kernel/86wmjwvatn.wl-maz@kernel.org/ In Marc's kernel configuration, the .head.text and .rodata.text sections end up more than 128MiB apart, requiring a veneer to branch between the two: | [mark@lakrids:~/src/linux]% usekorg 14.1.0 aarch64-linux-objdump -t vmlinux | grep -w _text | ffff800080000000 g .head.text 0000000000000000 _text | [mark@lakrids:~/src/linux]% usekorg 14.1.0 aarch64-linux-objdump -t vmlinux | grep -w primary_entry | ffff8000889df0e0 g .rodata.text 000000000000006c primary_entry, ... consequently, LLD inserts a position-dependent veneer for the branch from _stext (in .head.text) to primary_entry (in .rodata.text): | ffff800080000000 <_text>: | ffff800080000000: fa405a4d ccmp x18, #0x0, #0xd, pl // pl = nfrst | ffff800080000004: 14003fff b ffff800080010000 <__AArch64AbsLongThunk_primary_entry> ... | ffff800080010000 <__AArch64AbsLongThunk_primary_entry>: | ffff800080010000: 58000050 ldr x16, ffff800080010008 <__AArch64AbsLongThunk_primary_entry+0x8> | ffff800080010004: d61f0200 br x16 | ffff800080010008: 889df0e0 .word 0x889df0e0 | ffff80008001000c: ffff8000 .word 0xffff8000 ... and as this is executed early in boot before the kernel is mapped in TTBR1 this results in a silent boot failure. Fix this by passing '--pic-veneer' to the linker, which will cause the linker to use position-independent veneers, e.g. | ffff800080000000 <_text>: | ffff800080000000: fa405a4d ccmp x18, #0x0, #0xd, pl // pl = nfrst | ffff800080000004: 14003fff b ffff800080010000 <__AArch64ADRPThunk_primary_entry> ... | ffff800080010000 <__AArch64ADRPThunk_primary_entry>: | ffff800080010000: f004e3f0 adrp x16, ffff800089c8f000 <__idmap_text_start> | ffff800080010004: 91038210 add x16, x16, #0xe0 | ffff800080010008: d61f0200 br x16 I've opted to pass '--pic-veneer' unconditionally, as: * In addition to solving the boot failure, these sequences are generally nicer as they require fewer instructions and don't need to perform data accesses. * While the position-independent veneer sequences have a limited +/-2GiB range, this is not a new restriction. Even kernels built with CONFIG_RELOCATABLE=n are limited to 2GiB in size as we have several structues using 32-bit relative offsets and PPREL32 relocations, which are similarly limited to +/-2GiB in range. These include extable entries, jump table entries, and alt_instr entries. * GNU LD defaults to using position-independent veneers, and supports the same '--pic-veneer' option, so this change is not expected to adversely affect GNU LD. I've tested with GNU LD 2.30 to 2.42 inclusive and LLVM 13.0.1 to 19.1.0 inclusive, using the kernel.org binaries from: * https://mirrors.edge.kernel.org/pub/tools/crosstool/ * https://mirrors.edge.kernel.org/pub/tools/llvm/ Signed-off-by: Mark Rutland <mark.rutland@arm.com> Reported-by: Marc Zyngier <maz@kernel.org> Cc: Ard Biesheuvel <ardb@kernel.org> Cc: Nathan Chancellor <nathan@kernel.org> Cc: Nick Desaulniers <ndesaulniers@google.com> Cc: Will Deacon <will@kernel.org> Acked-by: Ard Biesheuvel <ardb@kernel.org> Reviewed-by: Nathan Chancellor <nathan@kernel.org> Link: https://lore.kernel.org/r/20240927101838.3061054-1-mark.rutland@arm.com Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> |

Fix the build by defining empty helper functions the same way the old

same situation.
Maybe we could instead have made the call sites conditional, since the
callers (kvm_arch_{en,dis}able_virtualization()) have an empty weak
fallback. I'll leave that to the kvm people to argue about, this at
least gets the build going for that particular config.

i2c-for-6.12-rc1-additional_fixes
I2C host fixes for v6.12-rc1 (from Andi) The DesignWare driver now has the correct ENABLE-ABORT sequence, ensuring ABORT can always be sent when needed. In the SynQuacer controller we now check for PCLK as an optional clock, allowing ACPI to directly provide the clock rate. The recent KEBA driver required a dependency fix in Kconfig. The XIIC driver now has a corrected power suspend sequence. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEOZGx6rniZ1Gk92RdFA3kzBSgKbYFAmb5Ex0ACgkQFA3kzBSg KbbNIxAAm1GYB7hSOoIZtv7amoMOJYPqEEh037/9RITF9U8zFL9JBWTePR+ksv6W 0FA4aEUYq8RyaJeQEVDHOdONiDJeYwVM8uxF02rwYx4tJYlLeh4J0H+AXnGPxQpO 17woQt1fx5hdtdyx+aJ6Zr4eJCo9XUaCwjvEQH4oZE2PFesP3b/9HSBq82gFBSHA lEnY1F/SfMNeF90y74f93fiZJLQNdfYKtzMS8iZ5eGVjokXcPP7TfrxIOughRlVT h+cNQaGd7g4YrYvMrTTDiNu8Bnc5nJcjyOcaQsXOpCnxljH4gb1V39RPQ6ATvTBQ uEPQCBU2ibZt2AbRcyWNRkw9sAuHdyOm0wv09ZsChpXafcM9BjzfF/xn6DlQuf64 d1COXxpBN5yI/4AU/Juojoy5/C8fMj81VtveXXlaISsyZzUo49XwM263PSXgkO8y 39A50Px1uVdeAjnVOu9Tsg/fJuAJRolIOVpw+/jWRZ1OXidp4MtmzL8bf2gXH7ts 4F7G8BOtoLXRM56AeO15EQ7YLJaw/03jb57EB+lREqy0qLDFJ0d13o+VcRmCvVK2 uK4RSN/y7poOOSaXnf5Wm61XYV8yu4XTyR8hN6EP/hsBcM0o1DLi4nLoI7S9QMjc +ic0In9qQDo90oTeF3tE+ijCQUTAOzR4wids1DjQuUBleUu71C0= =CZPe -----END PGP SIGNATURE----- Merge tag 'i2c-for-6.12-rc1-additional_fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c fixes from Wolfram Sang: - fix DesignWare driver ENABLE-ABORT sequence, ensuring ABORT can always be sent when needed - check for PCLK in the SynQuacer controller as an optional clock, allowing ACPI to directly provide the clock rate - KEBA driver Kconfig dependency fix - fix XIIC driver power suspend sequence * tag 'i2c-for-6.12-rc1-additional_fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: i2c: xiic: Fix pm_runtime_set_suspended() with runtime pm enabled i2c: keba: I2C_KEBA should depend on KEBA_CP500 i2c: synquacer: Deal with optional PCLK correctly i2c: designware: fix controller is holding SCL low while ENABLE bit is disabled |

bcachefs fixes for 6.11-rc1
Assorted minor syzbot fixes, and for bigger stuff:
- Fix two disk accounting rewrite bugs
- Disk accounting keys use the version field of bkey so that journal
replay can tell which updates have been applied to the btree. This is
set in the transaction commit path, after we've gotten our journal
reservation (and our time ordering), but the
BCH_TRANS_COMMIT_skip_accounting_apply flag that journal replay uses
was incorrectly skipping this for new updates generated prior to
journal replay.
This fixes the underlying cause of an assertion pop in
disk_accounting_read.
- A couple fixes for disk accounting + device removal. Checking if
acocunting replicas entries were marked in the superblock was being
done at the wrong point, when deltas in the journal could still zero
them out, and then additionally we'd try to add a missing replicas
entry to the superblock without checking if it referred to an invalid
(removed) device.
- A whole slew of repair fixes
- fix infinite loop in propagate_key_to_snapshot_leaves(), this fixes
an infinite loop when repairing a filesystem with many snapshots
- fix incorrect transaction restart handling leading to occasional
"fsck counted ..." warnings"
- fix warning in __bch2_fsck_err() for bkey fsck errors
- check_inode() in fsck now correctly checks if the filesystem was
clean
- there shouldn't be pending logged ops if the fs was clean, we now
check for this
- remove_backpointer() doesn't remove a dirent that doesn't actually
point to the inode
- many more fsck errors are AUTOFIX

Reduce Coccinelle choices in string_choices.cocci
The isomorphism neg_if_exp negates the test of a ?: conditional, making it unnecessary to have an explicit case for a negated test with the branches inverted. At the same time, we can disable neg_if_exp in cases where a different API function may be more suitable for a negated test. Finally, in the non-patch cases, E matches an expression with parentheses around it, so there is no need to mention () explicitly in the pattern. The () are still needed in the patch cases, because we want to drop them, if they are present. Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr> |

x86:
* KVM currently invalidates the entirety of the page tables, not just
those for the memslot being touched, when a memslot is moved or deleted.
The former does not have particularly noticeable overhead, but Intel's
TDX will require the guest to re-accept private pages if they are
dropped from the secure EPT, which is a non starter. Actually,
the only reason why this is not already being done is a bug which
was never fully investigated and caused VM instability with assigned
GeForce GPUs, so allow userspace to opt into the new behavior.
* Advertise AVX10.1 to userspace (effectively prep work for the "real" AVX10
functionality that is on the horizon).
* Rework common MSR handling code to suppress errors on userspace accesses to
unsupported-but-advertised MSRs. This will allow removing (almost?) all of
KVM's exemptions for userspace access to MSRs that shouldn't exist based on
the vCPU model (the actual cleanup is non-trivial future work).
* Rework KVM's handling of x2APIC ICR, again, because AMD (x2AVIC) splits the
64-bit value into the legacy ICR and ICR2 storage, whereas Intel (APICv)
stores the entire 64-bit value at the ICR offset.
* Fix a bug where KVM would fail to exit to userspace if one was triggered by
a fastpath exit handler.
* Add fastpath handling of HLT VM-Exit to expedite re-entering the guest when
there's already a pending wake event at the time of the exit.
* Fix a WARN caused by RSM entering a nested guest from SMM with invalid guest
state, by forcing the vCPU out of guest mode prior to signalling SHUTDOWN
(the SHUTDOWN hits the VM altogether, not the nested guest)
* Overhaul the "unprotect and retry" logic to more precisely identify cases
where retrying is actually helpful, and to harden all retry paths against
putting the guest into an infinite retry loop.
* Add support for yielding, e.g. to honor NEED_RESCHED, when zapping rmaps in
the shadow MMU.
* Refactor pieces of the shadow MMU related to aging SPTEs in prepartion for
adding multi generation LRU support in KVM.
* Don't stuff the RSB after VM-Exit when RETPOLINE=y and AutoIBRS is enabled,
i.e. when the CPU has already flushed the RSB.
* Trace the per-CPU host save area as a VMCB pointer to improve readability
and cleanup the retrieval of the SEV-ES host save area.
* Remove unnecessary accounting of temporary nested VMCB related allocations.
* Set FINAL/PAGE in the page fault error code for EPT violations if and only
if the GVA is valid. If the GVA is NOT valid, there is no guest-side page
table walk and so stuffing paging related metadata is nonsensical.
* Fix a bug where KVM would incorrectly synthesize a nested VM-Exit instead of
emulating posted interrupt delivery to L2.
* Add a lockdep assertion to detect unsafe accesses of vmcs12 structures.
* Harden eVMCS loading against an impossible NULL pointer deref (really truly
should be impossible).
* Minor SGX fix and a cleanup.
* Misc cleanups
Generic:
* Register KVM's cpuhp and syscore callbacks when enabling virtualization in
hardware, as the sole purpose of said callbacks is to disable and re-enable
virtualization as needed.
* Enable virtualization when KVM is loaded, not right before the first VM
is created. Together with the previous change, this simplifies a
lot the logic of the callbacks, because their very existence implies
virtualization is enabled.
* Fix a bug that results in KVM prematurely exiting to userspace for coalesced
MMIO/PIO in many cases, clean up the related code, and add a testcase.
* Fix a bug in kvm_clear_guest() where it would trigger a buffer overflow _if_
the gpa+len crosses a page boundary, which thankfully is guaranteed to not
happen in the current code base. Add WARNs in more helpers that read/write
guest memory to detect similar bugs.
Selftests:
* Fix a goof that caused some Hyper-V tests to be skipped when run on bare
metal, i.e. NOT in a VM.
* Add a regression test for KVM's handling of SHUTDOWN for an SEV-ES guest.
* Explicitly include one-off assets in .gitignore. Past Sean was completely
wrong about not being able to detect missing .gitignore entries.
* Verify userspace single-stepping works when KVM happens to handle a VM-Exit
in its fastpath.
* Misc cleanups
