tools/power turbostat: Honor --show CPU, even when even when num_cpus=1
Honor --show CPU and --show Core when "topo.num_cpus == 1". Previously turbostat assumed that on a 1-CPU system, these columns should never appear. Honoring these flags makes it easier for several programs that parse turbostat output. Signed-off-by: Patryk Wlazlyn <patryk.wlazlyn@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com> |

tools/power turbostat: Fix trailing '\n' parsing
parse_cpu_string() parses the string input either from command line or
from /sys/fs/cgroup/cpuset.cpus.effective to get a list of CPUs that
turbostat can run with.
The cpu string returned by /sys/fs/cgroup/cpuset.cpus.effective contains
a trailing '\n', but strtoul() fails to treat this as an error.
That says, for the code below
val = ("\n", NULL, 10);
val returns 0, and errno is also not set.
As a result, CPU0 is erroneously considered as allowed CPU and this
causes failures when turbostat tries to run on CPU0.
get_counters: Could not migrate to CPU 0
...
turbostat: re-initialized with num_cpus 8, allowed_cpus 5
get_counters: Could not migrate to CPU 0
Add a check to return immediately if '\n' or '\0' is detected.
Fixes:

tools/power turbostat: Allow using cpu device in perf counters on hybrid platforms
Intel hybrid platforms expose different perf devices for P and E cores.
Instead of one, "/sys/bus/event_source/devices/cpu" device, there are
"/sys/bus/event_source/devices/{cpu_core,cpu_atom}".
This, however makes it more complicated for the user,
because most of the counters are available on both and had to be
handled manually.
This patch allows users to use "virtual" cpu device that is seemingly
translated to cpu_core and cpu_atom perf devices, depending on the type
of a CPU we are opening the counter for.

PCI/pwrctrl: Unregister platform device only if one actually exists
If a PCI device has an associated device_node with power supplies,
pci_bus_add_device() creates platform devices for use by pwrctrl. When the
PCI device is removed, pci_stop_dev() uses of_find_device_by_node() to
locate the related platform device, then unregisters it.
But when we remove a PCI device with no associated device node,
dev_of_node(dev) is NULL, and of_find_device_by_node(NULL) returns the
first device with "dev->of_node == NULL". The result is that we (a)
mistakenly unregister a completely unrelated platform device, leading to
issues like the first trace below, and (b) dereference the NULL pointer
from dev_of_node() when clearing OF_POPULATED, as in the second trace.
Unregister a platform device only if there is one associated with this PCI
device. This resolves issues seen when doing:
# echo 1 > /sys/bus/pci/devices/.../remove
Sample issue from unregistering the wrong platform device:

sh: intc: Fix use-after-free bug in register_intc_controller()
In the error handling for this function, d is freed without ever
removing it from intc_list which would lead to a use after free.
To fix this, let's only add it to the list after everything has
succeeded.

Char/Misc/IIO/Whatever driver subsystem updates for 6.13-rc1
Here is the "big and hairy" char/misc/iio and other small driver
subsystem updates for 6.13-rc1. Sorry for doing this at the end of the
merge window, conference and holiday travel got in the way on my side
(hence the 5am pull request emails...)
Loads of things in here, and even a fun merge conflict!
- rust misc driver bindings and other rust changes to make misc
drivers actually possible. I think this is the tipping point,
expect to see way more rust drivers going forward now that these
bindings are present. Next merge window hopefully we will have pci
and platform drivers working, which will fully enable almost all
driver subsystems to start accepting (or at least getting) rust
drivers. This is the end result of a lot of work from a lot of
people, congrats to all of them for getting this far, you've proved
many of us wrong in the best way possible, working code :)
- IIO driver updates, too many to list individually, that subsystem
keeps growing and growing...
- Interconnect driver updates
- nvmem driver updates
- pwm driver updates
- platform_driver::remove() fixups, loads of them
- counter driver updates
- misc driver updates (keba?)
- binder driver updates and fixes
- loads of other small char/misc/etc driver updates and additions,
full details in the shortlog.
Note, there is a semi-hairy rust merge conflict when pulling this. The
resolution has been in linux-next for a while and can be seen here:
https://lore.kernel.org/all/20241111173459.2646d4af@canb.auug.org.au/
All of these have been in linux-next for a while, with no other reported
issues other than that merge conflict.

Driver core changes for 6.13-rc1
Here is a small set of driver core changes for 6.13-rc1.
Nothing major for this merge cycle, except for the 2 simple merge
conflicts are here just to make life interesting.
Included in here are:
- sysfs core changes and preparations for more sysfs api cleanups that
can come through all driver trees after -rc1 is out
- fw_devlink fixes based on many reports and debugging sessions
- list_for_each_reverse() removal, no one was using it!
- last-minute seq_printf() format string bug found and fixed in many
drivers all at once.
- minor bugfixes and changes full details in the shortlog
As mentioned above, there is 2 merge conflicts with your tree, one is
where the file is removed (easy enough to resolve), the second is a
build time error, that has been found in linux-next and the fix can be
seen here:
https://lore.kernel.org/r/20241107212645.41252436@canb.auug.org.au
Other than that, the changes here have been in linux-next with no other
reported issues.

Staging driver changes for 6.13-rc1
Here is the big set of staging driver changes for 6.13-rc1.
Lots of changes this merge cycle, drivers removed and drivers added.
Highlights include:
- removals of the following staging drivers due to no forward progress
and no one having either the hardware or the time/energy to deal
with them anymore:
- fieldbus
- gdm724x
- olpc_dcon
- rtl8712
- rts5208
- vt6655
- vt6656
If anyone has this hardware and wants to work on the drivers, it can
be an easy revert to get them back.
- addition of the gpib driver subsystem. Lots of drivers for
really old and semi-old interfaces to lab equipments. We expect lots
of churn in these drivers as they get cleaned up to "working" order.
These were added at the request of a user and the maintainer/author
of them is helping out with the effort
- loads and loads of tiny coding style cleanups for almost all staging
drivers. Too many to list, see the shortlog for details.
Note, this pull request contains a portion of the wireless tree, as the
removal of some of the staging wifi drivers came in through there to
coordinate things. These should already be in your tree already, so the
diffstat will (and should) look different when you do your merge.
All of these have been in linux-next for a very long time with no
reported issues.

btrfs: fix lockdep warnings on io_uring encoded reads
Lockdep doesn't like the fact that btrfs_uring_read_extent() returns to
userspace still holding the inode lock, even though we release it once
the I/O finishes. Add calls to rwsem_release() and rwsem_acquire_read() to
work round this.

btrfs: ref-verify: fix use-after-free after invalid ref action
At btrfs_ref_tree_mod() after we successfully inserted the new ref entry
(local variable 'ref') into the respective block entry's rbtree (local
variable 'be'), if we find an unexpected action of BTRFS_DROP_DELAYED_REF,
we error out and free the ref entry without removing it from the block
entry's rbtree. Then in the error path of btrfs_ref_tree_mod() we call
btrfs_free_ref_cache(), which iterates over all block entries and then
calls free_block_entry() for each one, and there we will trigger a
use-after-free when we are called against the block entry to which we
added the freed ref entry to its rbtree, since the rbtree still points
to the block entry, as we didn't remove it from the rbtree before freeing
it in the error path at btrfs_ref_tree_mod(). Fix this by removing the
new ref entry from the rbtree before freeing it.
Syzbot report this with the following stack traces:

btrfs: add a sanity check for btrfs root in btrfs_search_slot()
Syzbot reports a null-ptr-deref in btrfs_search_slot().
The reproducer is using rescue=ibadroots, and the extent tree root is
corrupted thus the extent tree is NULL.
When scrub tries to search the extent tree to gather the needed extent
info, btrfs_search_slot() doesn't check if the target root is NULL or
not, resulting the null-ptr-deref.
Add sanity check for btrfs root before using it in btrfs_search_slot().

btrfs: don't loop for nowait writes when checking for cross references
When checking for delayed refs when verifying if there are cross
references for a data extent, we stop if the path has nowait set and we
can't try lock the delayed ref head's mutex, returning -EAGAIN with the
goal of making a write fallback to a blocking context. However we ignore
the -EAGAIN at btrfs_cross_ref_exist() when check_delayed_ref() returns
it, and keep looping instead of immediately returning the -EAGAIN to the
caller.
Fix this by not looping if we get -EAGAIN and we have a nowait path.

block, bfq: fix bfqq uaf in bfq_limit_depth()
Set new allocated bfqq to bic or remove freed bfqq from bic are both
protected by bfqd->lock, however bfq_limit_depth() is deferencing bfqq
from bic without the lock, this can lead to UAF if the io_context is
shared by multiple tasks.
For example, test bfq with io_uring can trigger following UAF in v6.6:

selftests/hid: fix kfunc inclusions with newer bpftool
bpftool now embeds the kfuncs definitions directly in the generated vmlinux.h This is great, but because the selftests dir might be compiled with HID_BPF disabled, we have no guarantees to be able to compile the sources with the generated kfuncs. If we have the kfuncs, because we have the `__not_used` hack, the newly defined kfuncs do not match the ones from vmlinux.h and things go wrong. Prevent vmlinux.h to define its kfuncs and also add the missing `__weak` symbols for our custom kfuncs definitions Link: https://patch.msgid.link/20241128-fix-new-bpftool-v1-1-c9abdf94a719@kernel.org Signed-off-by: Benjamin Tissoires <bentiss@kernel.org> |

io_uring/tctx: work around xa_store() allocation error issue
syzbot triggered the following WARN_ON: WARNING: CPU: 0 PID: 16 at io_uring/tctx.c:51 __io_uring_free+0xfa/0x140 io_uring/tctx.c:51 which is the WARN_ON_ONCE(!xa_empty(&tctx->xa)); sanity check in __io_uring_free() when a io_uring_task is going through its final put. The syzbot test case includes injecting memory allocation failures, and it very much looks like xa_store() can fail one of its memory allocations and end up with ->head being non-NULL even though no entries exist in the xarray. Until this issue gets sorted out, work around it by attempting to iterate entries in our xarray, and WARN_ON_ONCE() if one is found.

posix-timers: Target group sigqueue to current task only if not exiting
A sigqueue belonging to a posix timer, which target is not a specific
thread but a whole thread group, is preferrably targeted to the current
task if it is part of that thread group.
However nothing prevents a posix timer event from queueing such a
sigqueue from a reaped yet running task. The interruptible code space
between exit_notify() and the final call to schedule() is enough for
posix_timer_fn() hrtimer to fire.
If that happens while the current task is part of the thread group
target, it is proposed to handle it but since its sighand pointer may
have been cleared already, the sigqueue is dropped even if there are
other tasks running within the group that could handle it.
As a result posix timers with thread group wide target may miss signals
when some of their threads are exiting.
Fix this with verifying that the current task hasn't been through
exit_notify() before proposing it as a preferred target so as to ensure
that its sighand is still here and stable.
complete_signal() might still reconsider the choice and find a better
target within the group if current has passed retarget_shared_pending()
already.

btrfs: sysfs: advertise experimental features only if CONFIG_BTRFS_EXPERIMENTAL=y
We are advertising experimental features through sysfs if
CONFIG_BTRFS_DEBUG is set, without looking if CONFIG_BTRFS_EXPERIMENTAL
is set. This is wrong as it will result in reporting experimental
features as supported when CONFIG_BTRFS_EXPERIMENTAL is not set but
CONFIG_BTRFS_DEBUG is set.
Fix this by checking for CONFIG_BTRFS_EXPERIMENTAL instead of
CONFIG_BTRFS_DEBUG.

btrfs: fix deadlock between transaction commits and extent locks

And while it's waiting for the transaction to complete, it's holding an extent range locked in the same inode that task B is operating, which causes a deadlock between these 3 tasks. The extent range for the inode was locked at the start of the fiemap operation, early at extent_fiemap(). In short these tasks deadlock because: 1) Task A is waiting for task B to release its transaction handle; 2) Task B is waiting to lock an extent range for an inode while holding a transaction handle open; 3) Task C is waiting for the current transaction to complete (for task A to finish the transaction commit) while holding the extent range for the inode locked, so task B can't progress and release its transaction handle. This results in an ABBA deadlock involving transaction commits and extent locks. Extent locks are higher level locks, like inode VFS locks, and should always be acquired before joining or starting a transaction, but recently commit |

Tracing updates for 6.13:
- Add trace flag for NEED_RESCHED_LAZY Now that NEED_RESCHED_LAZY is upstream, add it to the status bits of the common_flags. This will now show when the NEED_RESCHED_LAZY flag is set that is used for debugging latency issues in the kernel via a trace. - Remove leftover "__idx" variable when SRCU was removed from the tracepoint code - Add rcu_tasks_trace guard To add a guard() around the tracepoint code, a rcu_tasks_trace guard needs to be created first. - Remove __DO_TRACE() macro and just call __DO_TRACE_CALL() directly The DO_TRACE() macro has conditional locking depending on what was passed into the macro parameters. As the guts of the macro has been moved to __DO_TRACE_CALL() to handle static call logic, there's no reason to keep the __DO_TRACE() macro around. It is better to just do the locking in place without the conditionals and call __DO_TRACE_CALL() from those locations. The "cond" passed in can also be moved out of that macro. This simplifies the code. - Remove the "cond" from the system call tracepoint macros The "cond" variable was added to allow some tracepoints to check a condition within the static_branch (jump/nop) logic. The system calls do not need this. Removing it simplifies the code. - Replace scoped_guard() with just guard() in the tracepoint logic guard() works just as well as scoped_guard() in the tracepoint logic and the scoped_guard() causes some issues. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZ0dGmBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qsZkAP9cm2psIGp2n1BgVjA+0tBRQJUnexEG RualDkF5wAETLwD9FNFI/EUwDR/E8gNt0SY309EJZ1ijRiLjtU0spbQmdgs= =awid -----END PGP SIGNATURE----- Merge tag 'trace-v6.13-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull more tracing updates from Steven Rostedt: - Add trace flag for NEED_RESCHED_LAZY Now that NEED_RESCHED_LAZY is upstream, add it to the status bits of the common_flags.
