perf synthetic-events: Avoid unnecessary memset
Make sure the memset of a synthesized event only zeros the necessary tracing data part of the event, as a full event can be over 4kb in size.

perf python: Fix the build on 32-bit arm by including missing "util/sample.h"
The 32-bit arm build system will complain:
tools/perf/util/python.c:75:28: error: field ‘sample’ has incomplete type
75 | struct perf_sample sample;
However, arm64 build system doesn't complain this.
The root cause is arm64 define "HAVE_KVM_STAT_SUPPORT := 1" in
tools/perf/arch/arm64/Makefile, but arm arch doesn't define this. This
will lead to kvm-stat.h include other header files on arm64 build
system, especially "util/sample.h" for util/python.c.
This will try to directly include "util/sample.h" for "util/python.c" to
avoid such build issue on arm platform.

perf annotate-data: Check variables in every scope
Sometimes it matches a variable in the inner scope but it fails because
the actual access can be on a different type. Let's try variables in
every scope and choose the best one using is_better_type().
I have an example with update_blocked_averages(), at first it found a
variable (__mptr) but it's a void pointer. So it moved on to the upper
scope and found another variable (cfs_rq).
$ perf --debug type-profile annotate --data-type --stdio
...
-----------------------------------------------------------
find data type for 0x140(reg14) at update_blocked_averages+0x2db
CU for kernel/sched/fair.c (die:0x12dd892)
frame base: cfa=1 fbreg=7
found "__mptr" (die: 0x13022f1) in scope=4/4 (die: 0x13022e8) failed: no/void pointer
variable location: base=reg14, offset=0x140
type='void*' size=0x8 (die:0x12dd8f9)
found "cfs_rq" (die: 0x1301721) in scope=3/4 (die: 0x130171c) type_offset=0x140
variable location: reg14
type='struct cfs_rq' size=0x1c0 (die:0x12e37e5)
final type: type='struct cfs_rq' size=0x1c0 (die:0x12e37e5)
IIUC the scope is like below:
1: update_blocked_averages
2: __update_blocked_fair
3: for_each_leaf_cfs_rq_safe
4: list_entry -> (container_of)
The container_of is implemented like:
#define container_of(ptr, type, member) ({ \
void *__mptr = (void *)(ptr); \
static_assert(__same_type(*(ptr), ((type *)0)->member) || \
__same_type(*(ptr), void), \
"pointer type mismatch in container_of()"); \
((type *)(__mptr - offsetof(type, member))); })
That's why we see the __mptr variable first but it failed since it has
no type information.
Then for_each_leaf_cfs_rq_safe() is defined as
#define for_each_leaf_cfs_rq_safe(rq, cfs_rq, pos) \
list_for_each_entry_safe(cfs_rq, pos, &rq->leaf_cfs_rq_list, \
leaf_cfs_rq_list)
Note that the access was 0x140(r14). And the cfs_rq has
leaf_cfs_rq_list at the 0x140. So it converts the list_head pointer to
a pointer to struct cfs_rq here.
$ pahole --hex -C cfs_rq vmlinux | grep 140
struct cfs_rq struct list_head leaf_cfs_rq_list; /* 0x140 0x10 */

perf annotate-data: Add is_better_type() helper
Sometimes more than one variables are located in the same register or a stack slot. Or it can overwrite existing information with others. I found this is not helpful in some cases so it needs to update the type information from the variable only if it's better. But it's hard to know which one is better, so we needs heuristics. :) As it deals with memory accesses, the location should have a pointer or something similar (like array or reference). So if it had an integer type and a variable is a pointer, we can take the variable's type to resolve the target of the access. If it has a pointer type and a variable with the same location has a different pointer type, it'll take one with bigger target type. This can be useful when the target type embeds a smaller type (like list header or RB-tree node) at the beginning so their location is same.

perf annotate-data: Fix off-by-one in location range check
The location list will have entries with half-open addressing like
[start, end) which means it doesn't include the end address. So it
should skip entries at the end address and match to the next entry.
An example location list looks like this (from readelf -wo):
00237876 ffffffff8110d32b (base address)
0023787f v000000000000000 v000000000000002 views at 00237868 for:

The first entry at 0023787f has [8110d32b, 8110d4eb) (omitting the
ffffffff at the beginning), and the second one has [8110d4eb, 8110d50b).

perf dwarf-aux: Check allowed location expressions when collecting variables
It missed to call check_allowed_ops() in __die_collect_vars_cb() so it
can take variables with complex location expression incorrectly.
For example, I found some variable has this expression.
015d8df8 ffffffff81aacfb3 (base address)
015d8e01 v000000000000004 v000000000000000 views at 015d8df2 for:
ffffffff81aacfb3 ffffffff81aacfd2 (DW_OP_fbreg: -176; DW_OP_deref;
DW_OP_plus_uconst: 332; DW_OP_deref_size: 4;
DW_OP_lit1; DW_OP_shra; DW_OP_const1u: 64;
DW_OP_minus; DW_OP_stack_value)
015d8e14 v000000000000000 v000000000000000 views at 015d8df4 for:
ffffffff81aacfd2 ffffffff81aacfd7 (DW_OP_reg3 (rbx))
015d8e19 v000000000000000 v000000000000000 views at 015d8df6 for:

DW_OP_lit1; DW_OP_shra; DW_OP_const1u: 64;
DW_OP_minus; DW_OP_stack_value)
015d8e2c <End of list>
It looks like '((int *)(-176(%rbp) + 332) >> 1) - 64' but the current
code thought it's just -176(%rbp) and processed the variable incorrectly.
It should reject such a complex expression if check_allowed_ops()
doesn't like it. :)

perf stat: Display iostat headers correctly
Currently we'll only print metric headers for metric leader in
aggregration mode. This will make `perf iostat` header not shown
since it'll aggregrated globally but don't have metric events:
root@ubuntu204:/home/yang/linux/tools/perf# ./perf stat --iostat --timeout 1000
Performance counter stats for 'system wide':
port
0000:00 0 0 0 0
0000:80 0 0 0 0
[...]
Fix this by excluding the iostat in the check of printing metric
headers. Then we can see the headers:
root@ubuntu204:/home/yang/linux/tools/perf# ./perf stat --iostat --timeout 1000
Performance counter stats for 'system wide':
port Inbound Read(MB) Inbound Write(MB) Outbound Read(MB) Outbound Write(MB)
0000:00 0 0 0 0
0000:80 0 0 0 0

Rust fixes for v6.11
- Fix '-Os' Rust 1.80.0+ builds adding more intrinsics (also tweaked
in upstream Rust for the upcoming 1.82.0).
- Fix support for the latest version of rust-analyzer due to a change
on rust-analyzer config file semantics (considered a fix since most
developers use the latest version of the tool, which is the only one
actually supported by upstream). I am discussing stability of the
config file with upstream -- they may be able to start versioning it.
- Fix GCC 14 builds due to '-fmin-function-alignment' not skipped for
libclang (bindgen).
- A couple Kconfig fixes around '{RUSTC,BINDGEN}_VERSION_TEXT' to
suppress error messages in a foreign architecture chroot and to use a
proper default format.
- Clean 'rust-analyzer' target warning due to missing recursive make
invocation mark.
- Clean Clippy warning due to missing indentation in docs.
- Clean LLVM 19 build warning due to removed 3dnow feature upstream.

A couple of fixes for tracing:
- Prevent a NULL pointer dereference in the error path of RTLA tool
- Fix an infinite loop bug when reading from the ring buffer when closed.
If there's a thread trying to read the ring buffer and it gets closed
by another thread, the one reading will go into an infinite loop
when the buffer is empty instead of exiting back to user space.

thermal: gov_bang_bang: Use governor_data to reduce overhead
After running once, the for_each_trip_desc() loop in bang_bang_manage() is pure needless overhead because it is not going to make any changes unless a new cooling device has been bound to one of the trips in the thermal zone or the system is resuming from sleep. For this reason, make bang_bang_manage() set governor_data for the thermal zone and check it upfront to decide whether or not it needs to do anything. However, governor_data needs to be reset in some cases to let bang_bang_manage() know that it should walk the trips again, so add an .update_tz() callback to the governor and make the core additionally invoke it during system resume. To avoid affecting the other users of that callback unnecessarily, add a special notification reason for system resume, THERMAL_TZ_RESUME, and also pass it to __thermal_zone_device_update() called during system resume for consistency.

thermal: gov_bang_bang: Add .manage() callback
After recent changes, the Bang-bang governor may not adjust the
initial configuration of cooling devices to the actual situation.
Namely, if a cooling device bound to a certain trip point starts in
the "on" state and the thermal zone temperature is below the threshold
of that trip point, the trip point may never be crossed on the way up
in which case the state of the cooling device will never be adjusted
because the thermal core will never invoke the governor's
.trip_crossed() callback. [Note that there is no issue if the zone
temperature is at the trip threshold or above it to start with because
.trip_crossed() will be invoked then to indicate the start of thermal
mitigation for the given trip.]
To address this, add a .manage() callback to the Bang-bang governor
and use it to ensure that all of the thermal instances managed by the
governor have been initialized properly and the states of all of the
cooling devices involved have been adjusted to the current zone
temperature as appropriate.

When interrupt is turned on while a lock holding by spin_lock_irq it
throws a warning because of potential deadlock.
blk_mq_prep_dispatch_rq
blk_mq_get_driver_tag
__blk_mq_get_driver_tag
__blk_mq_alloc_driver_tag
blk_mq_tag_busy -> tag is already busy
// failed to get driver tag
blk_mq_mark_tag_wait
spin_lock_irq(&wq->lock) -> lock A (&sbq->ws[i].wait)
__add_wait_queue(wq, wait) -> wait queue active
blk_mq_get_driver_tag
__blk_mq_tag_busy
-> 1) tag must be idle, which means there can't be inflight IO
spin_lock_irq(&tags->lock) -> lock B (hctx->tags)
spin_unlock_irq(&tags->lock) -> unlock B, turn on interrupt accidentally
-> 2) context must be preempt by IO interrupt to trigger deadlock.
As shown above, the deadlock is not possible in theory, but the warning
still need to be fixed.
Fix it by using spin_lock_irqsave to get lockB instead of spin_lock_irq.

tools build: Provide consistent build options for fixdep
The fixdep binary is being compiled and linked in one step. While the
host linker flags are passed to the compiler the host compiler flags are
missed.
That leads to build errors at least on x86_64, arm64 and s390 as result
of the compiler vs linker flags inconsistency. For example, during RPM
package build redhat-hardened-ld script is provided to gcc, while
redhat-hardened-cc1 script is missed.
Provide both KBUILD_HOSTCFLAGS and KBUILD_HOSTLDFLAGS to avoid that.

md/raid1: Fix data corruption for degraded array with slow disk
read_balance() will avoid reading from slow disks as much as possible, however, if valid data only lands in slow disks, and a new normal disk is still in recovery, unrecovered data can be read: raid1_read_request read_balance raid1_should_read_first -> return false choose_best_rdev -> normal disk is not recovered, return -1 choose_bb_rdev -> missing the checking of recovery, return the normal disk -> read unrecovered data Root cause is that the checking of recovery is missing in choose_bb_rdev(). Hence add such checking to fix the problem. Also fix similar problem in choose_slow_rdev(). Cc: stable@vger.kernel.org Fixes: |

Merge patch series "RISC-V: hwprobe: Misaligned scalar perf fix and rename"
Evan Green <evan@rivosinc.com> says: The CPUPERF0 hwprobe key was documented and identified in code as a bitmask value, but its contents were an enum. This produced incorrect behavior in conjunction with the WHICH_CPUS hwprobe flag. The first patch in this series fixes the bitmask/enum problem by creating a new hwprobe key that returns the same data, but is properly described as a value instead of a bitmask. The second patch renames the value definitions in preparation for adding vector misaligned access info. As of this version, the old defines are kept in place to maintain source compatibility with older userspace programs. * b4-shazam-merge: RISC-V: hwprobe: Add SCALAR to misaligned perf defines RISC-V: hwprobe: Add MISALIGNED_PERF key Link: https://lore.kernel.org/r/20240809214444.3257596-1-evan@rivosinc.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com> |

KEYS: trusted: dcp: fix leak of blob encryption key
Trusted keys unseal the key blob on load, but keep the sealed payload in
the blob field so that every subsequent read (export) will simply
convert this field to hex and send it to userspace.
With DCP-based trusted keys, we decrypt the blob encryption key (BEK)
in the Kernel due hardware limitations and then decrypt the blob payload.
BEK decryption is done in-place which means that the trusted key blob
field is modified and it consequently holds the BEK in plain text.
Every subsequent read of that key thus send the plain text BEK instead
of the encrypted BEK to userspace.
This issue only occurs when importing a trusted DCP-based key and
then exporting it again. This should rarely happen as the common use cases
are to either create a new trusted key and export it, or import a key
blob and then just use it without exporting it again.
Fix this by performing BEK decryption and encryption in a dedicated
buffer. Further always wipe the plain text BEK buffer to prevent leaking
the key via uninitialized memory.

KEYS: trusted: fix DCP blob payload length assignment
The DCP trusted key type uses the wrong helper function to store
the blob's payload length which can lead to the wrong byte order
being used in case this would ever run on big endian architectures.
Fix by using correct helper function.
