char: tpm: tpm-buf: Add sanity check fallback in read helpers
Fix Smatch-detected issue: drivers/char/tpm/tpm-buf.c:208 tpm_buf_read_u8() error: uninitialized symbol 'value'. drivers/char/tpm/tpm-buf.c:225 tpm_buf_read_u16() error: uninitialized symbol 'value'. drivers/char/tpm/tpm-buf.c:242 tpm_buf_read_u32() error: uninitialized symbol 'value'. Zero-initialize the return values in tpm_buf_read_u8(), tpm_buf_read_u16(), and tpm_buf_read_u32() to guard against uninitialized data in case of a boundary overflow. Add defensive initialization ensures the return values are always defined, preventing undefined behavior if the unexpected happens.

tracing fixes for 6.15:
- 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. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaCTZHBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qu04AQDjOS46Y8d58MuwjLrQAotOUnANZADz 7d+5snlcMjhqkAEAo+zc2z9LgqBAnv1VG3GEPgac0JmyPeOnqSJRWRpRXAM= =UveQ -----END PGP SIGNATURE----- Merge tag 'trace-v6.15-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace 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().

ring-buffer: Fix persistent buffer when commit page is the reader page
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
<...>-1137 [004] ..... 998.205323: sys_enter_fchownat: __syscall_nr=0x104 (260) dfd=0xffffff9c (4294967196) filename=(0xffffc90000a0002c) user=0x3e8 (1000) group=0xffffffff (4294967295) flag=0x0 (0

ftrace: Fix preemption accounting for stacktrace filter command
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:
$ echo ksys_read:stacktrace > set_ftrace_filter
<...>-410 [006] ..... 31.420396: <stack trace>
=> ksys_read
=> do_syscall_64

ftrace: Fix preemption accounting for stacktrace trigger command
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>
=> ftrace_syscall_enter
=> syscall_trace_enter
=> do_syscall_64

tracing: probes: Fix a possible race in trace_probe_log APIs
Since the shared trace_probe_log variable can be accessed and
modified via probe event create operation of kprobe_events,
uprobe_events, and dynamic_events, it should be protected.
In the dynamic_events, all operations are serialized by
`dyn_event_ops_mutex`. But kprobe_events and uprobe_events
interfaces are not serialized.
To solve this issue, introduces dyn_event_create(), which runs
create() operation under the mutex, for kprobe_events and
uprobe_events. This also uses lockdep to check the mutex is
held when using trace_probe_log* APIs.

sched_ext: Fixes for v6.15-rc6
A little bit invasive for rc6 but they're important fixes, pass tests fine
and won't break anything outside sched_ext.
- scx_bpf_cpuperf_set() calls internal functions that require the rq to be
locked. It assumed that the BPF caller has rq locked but that's not always
true. Fix it by tracking whether rq is currently held by the CPU and
grabbing it if necessary.
- bpf_iter_scx_dsq_new() was leaving the DSQ iterator in an uninitialized
state after an error. However, next() and destroy() can be called on an
iterator which failed initialization and thus they always need to be
initialized even after an init error. Fix by always initializing the
iterator.
- Remove duplicate BTF_ID_FLAGS() entries.

btrfs: add back warning for mount option commit values exceeding 300
The Btrfs documentation states that if the commit value is greater than

btrfs: fix folio leak in submit_one_async_extent()
If btrfs_reserve_extent() fails while submitting an async_extent for a
compressed write, then we fail to call free_async_extent_pages() on the
async_extent and leak its folios. A likely cause for such a failure
would be btrfs_reserve_extent() failing to find a large enough
contiguous free extent for the compressed extent.
I was able to reproduce this by:
1. mount with compress-force=zstd:3
2. fallocating most of a filesystem to a big file
3. fragmenting the remaining free space
4. trying to copy in a file which zstd would generate large compressed
extents for (vmlinux worked well for this)
Step 4. hits the memory leak and can be repeated ad nauseam to
eventually exhaust the system memory.
Fix this by detecting the case where we fallback to uncompressed
submission for a compressed async_extent and ensuring that we call
free_async_extent_pages().

btrfs: fix discard worker infinite loop after disabling discard
If the discard worker is running and there's currently only one block
group, that block group is a data block group, it's in the unused block
groups discard list and is being used (it got an extent allocated from it
after becoming unused), the worker can end up in an infinite loop if a
transaction abort happens or the async discard is disabled (during remount
or unmount for example).
This happens like this:
1) Task A, the discard worker, is at peek_discard_list() and
find_next_block_group() returns block group X;
2) Block group X is in the unused block groups discard list (its discard
index is BTRFS_DISCARD_INDEX_UNUSED) since at some point in the past
it become an unused block group and was added to that list, but then
later it got an extent allocated from it, so its ->used counter is not
zero anymore;
3) The current transaction is aborted by task B and we end up at
__btrfs_handle_fs_error() in the transaction abort path, where we call
btrfs_discard_stop(), which clears BTRFS_FS_DISCARD_RUNNING from
fs_info, and then at __btrfs_handle_fs_error() we set the fs to RO mode
(setting SB_RDONLY in the super block's s_flags field);
4) Task A calls __add_to_discard_list() with the goal of moving the block
group from the unused block groups discard list into another discard
list, but at __add_to_discard_list() we end up doing nothing because
btrfs_run_discard_work() returns false, since the super block has
SB_RDONLY set in its flags and BTRFS_FS_DISCARD_RUNNING is not set
anymore in fs_info->flags. So block group X remains in the unused block
groups discard list;
5) Task A then does a goto into the 'again' label, calls
find_next_block_group() again we gets block group X again. Then it
repeats the previous steps over and over since there are not other
block groups in the discard lists and block group X is never moved
out of the unused block groups discard list since
btrfs_run_discard_work() keeps returning false and therefore
__add_to_discard_list() doesn't move block group X out of that discard
list.
When this happens we can get a soft lockup report like this:

Pull x86 ITS mitigation from Dave Hansen:
"Mitigate Indirect Target Selection (ITS) issue.
I'd describe this one as a good old CPU bug where the behavior is
_obviously_ wrong, but since it just results in bad predictions it
wasn't wrong enough to notice. Well, the researchers noticed and also
realized that thus bug undermined a bunch of existing indirect branch
mitigations.
Thus the unusually wide impact on this one. Details:
ITS is a bug in some Intel CPUs that affects indirect branches
including RETs in the first half of a cacheline. Due to ITS such
branches may get wrongly predicted to a target of (direct or indirect)
branch that is located in the second half of a cacheline. Researchers
at VUSec found this behavior and reported to Intel.
Affected processors:
- Cascade Lake, Cooper Lake, Whiskey Lake V, Coffee Lake R, Comet
Lake, Ice Lake, Tiger Lake and Rocket Lake.
Scope of impact:
- Guest/host isolation:
When eIBRS is used for guest/host isolation, the indirect branches
in the VMM may still be predicted with targets corresponding to
direct branches in the guest.
- Intra-mode using cBPF:
cBPF can be used to poison the branch history to exploit ITS.
Realigning the indirect branches and RETs mitigates this attack
vector.
- User/kernel:
With eIBRS enabled user/kernel isolation is *not* impacted by ITS.
- Indirect Branch Prediction Barrier (IBPB):
Due to this bug indirect branches may be predicted with targets
corresponding to direct branches which were executed prior to IBPB.
This will be fixed in the microcode.
Mitigation:
As indirect branches in the first half of cacheline are affected, the
mitigation is to replace those indirect branches with a call to thunk that
is aligned to the second half of the cacheline.
RETs that take prediction from RSB are not affected, but they may be
affected by RSB-underflow condition. So, RETs in the first half of
cacheline are also patched to a return thunk that executes the RET aligned
to second half of cacheline"

Intra-mode BHI attacks via cBPF a.k.a IBTI-History was reported by researchers at VUSec. For hardware that doesn't support BHI_DIS_S, the recommended mitigation is to run the short software sequence followed by the IBHF instruction after cBPF execution. On hardware that does support BHI_DIS_S, enable BHI_DIS_S and execute the IBHF after cBPF execution. The Indirect Branch History Fence (IBHF) is a new instruction that prevents indirect branch target predictions after the barrier from using branch history from before the barrier while BHI_DIS_S is enabled. On older systems this will map to a NOP. It is recommended to add this fence at the end of the cBPF program to support VM migration. This instruction is required on newer parts with BHI_NO to fully mitigate against these attacks. The current code disables the mitigation for anything running with the SYS_ADMIN capability bit set. The intention was not to waste time mitigating a process that has access to anything it wants anyway" * tag 'ibti-hisory-for-linus-2025-05-06' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/bhi: Do not set BHI_DIS_S in 32-bit mode x86/bpf: Add IBHF call at end of classic BPF x86/bpf: Call branch history clearing sequence on exit |

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.

Input: xpad - fix Share button on Xbox One controllers
The Share button, if present, is always one of two offsets from the end of the file, depending on the presence of a specific interface. As we lack parsing for the identify packet we can't automatically determine the presence of that interface, but we can hardcode which of these offsets is correct for a given controller. More controllers are probably fixable by adding the MAP_SHARE_BUTTON in the future, but for now I only added the ones that I have the ability to test directly.

KVM x86 fixes for 6.15-rcN
- 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.

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
