timers/migration: Improve tracing
Trace points of inactive and active propagation are located at the end of the related functions. The interesting information of those trace points is the updated group state. When trace points are not located directly at the place where group state changed, order of trace points in traces could be confusing. Move inactive and active propagation trace points directly after update of group state values.

timers/migration: Move hierarchy setup into cpuhotplug prepare callback
When a CPU comes online the first time, it is possible that a new top level
group will be created. In general all propagation is done from the bottom
to top. This minimizes complexity and prevents possible races. But when a
new top level group is created, the formely top level group needs to be
connected to the new level. This is the only time, when the direction to
propagate changes is changed: the changes are propagated from top (new top
level group) to bottom (formerly top level group).
This introduces two races (see (A) and (B)) as reported by Frederic:
(A) This race happens, when marking the formely top level group as active,
but the last active CPU of the formerly top level group goes idle. Then
it's likely that formerly group is no longer active, but marked
nevertheless as active in new top level group:
[GRP0:0]
migrator = 0
active = 0
nextevt = KTIME_MAX
/ \
0 1 .. 7
active idle
0) Hierarchy has for now only 8 CPUs and CPU 0 is the only active CPU.
[GRP1:0]
migrator = TMIGR_NONE
active = NONE
nextevt = KTIME_MAX
\
[GRP0:0] [GRP0:1]
migrator = 0 migrator = TMIGR_NONE
active = 0 active = NONE
nextevt = KTIME_MAX nextevt = KTIME_MAX
/ \
0 1 .. 7 8
active idle !online
1) CPU 8 is booting and creates a new group in first level GRP0:1 and
therefore also a new top group GRP1:0. For now the setup code proceeded
only until the connected between GRP0:1 to the new top group. The
connection between CPU8 and GRP0:1 is not yet established and CPU 8 is
still !online.
[GRP1:0]
migrator = TMIGR_NONE
active = NONE
nextevt = KTIME_MAX
/ \
[GRP0:0] [GRP0:1]
migrator = 0 migrator = TMIGR_NONE
active = 0 active = NONE
nextevt = KTIME_MAX nextevt = KTIME_MAX
/ \
0 1 .. 7 8
active idle !online
2) Setup code now connects GRP0:0 to GRP1:0 and observes while in
tmigr_connect_child_parent() that GRP0:0 is not TMIGR_NONE. So it
prepares to call tmigr_active_up() on it. It hasn't done it yet.
[GRP1:0]
migrator = TMIGR_NONE
active = NONE
nextevt = KTIME_MAX
/ \
[GRP0:0] [GRP0:1]
migrator = TMIGR_NONE migrator = TMIGR_NONE
active = NONE active = NONE
nextevt = KTIME_MAX nextevt = KTIME_MAX
/ \
0 1 .. 7 8
idle idle !online
3) CPU 0 goes idle. Since GRP0:0->parent has been updated by CPU 8 with
GRP0:0->lock held, CPU 0 observes GRP1:0 after calling
tmigr_update_events() and it propagates the change to the top (no change
there and no wakeup programmed since there is no timer).
[GRP1:0]
migrator = GRP0:0
active = GRP0:0
nextevt = KTIME_MAX
/ \
[GRP0:0] [GRP0:1]
migrator = TMIGR_NONE migrator = TMIGR_NONE
active = NONE active = NONE
nextevt = KTIME_MAX nextevt = KTIME_MAX
/ \
0 1 .. 7 8
idle idle !online
4) Now the setup code finally calls tmigr_active_up() to and sets GRP0:0
active in GRP1:0
[GRP1:0]
migrator = GRP0:0
active = GRP0:0, GRP0:1
nextevt = KTIME_MAX
/ \
[GRP0:0] [GRP0:1]
migrator = TMIGR_NONE migrator = 8
active = NONE active = 8
nextevt = KTIME_MAX nextevt = KTIME_MAX
/ \ |
0 1 .. 7 8
idle idle active
5) Now CPU 8 is connected with GRP0:1 and CPU 8 calls tmigr_active_up() out
of tmigr_cpu_online().
[GRP1:0]
migrator = GRP0:0
active = GRP0:0
nextevt = T8
/ \
[GRP0:0] [GRP0:1]
migrator = TMIGR_NONE migrator = TMIGR_NONE
active = NONE active = NONE
nextevt = KTIME_MAX nextevt = T8
/ \ |
0 1 .. 7 8
idle idle idle
5) CPU 8 goes idle with a timer T8 and relies on GRP0:0 as the migrator.
But it's not really active, so T8 gets ignored.
--> The update which is done in third step is not noticed by setup code. So
a wrong migrator is set to top level group and a timer could get
ignored.
(B) Reading group->parent and group->childmask when an hierarchy update is
ongoing and reaches the formerly top level group is racy as those values
could be inconsistent. (The notation of migrator and active now slightly
changes in contrast to the above example, as now the childmasks are used.)
[GRP1:0]
migrator = TMIGR_NONE
active = 0x00
nextevt = KTIME_MAX
\
[GRP0:0] [GRP0:1]
migrator = TMIGR_NONE migrator = TMIGR_NONE
active = 0x00 active = 0x00
nextevt = KTIME_MAX nextevt = KTIME_MAX
childmask= 0 childmask= 1
parent = NULL parent = GRP1:0
/ \
0 1 .. 7 8
idle idle !online
childmask=1
1) Hierarchy has 8 CPUs. CPU 8 is at the moment in the process of onlining
but did not yet connect GRP0:0 to GRP1:0.
[GRP1:0]
migrator = TMIGR_NONE
active = 0x00
nextevt = KTIME_MAX
/ \
[GRP0:0] [GRP0:1]
migrator = TMIGR_NONE migrator = TMIGR_NONE
active = 0x00 active = 0x00
nextevt = KTIME_MAX nextevt = KTIME_MAX
childmask= 0 childmask= 1
parent = GRP1:0 parent = GRP1:0
/ \
0 1 .. 7 8
idle idle !online
childmask=1
2) Setup code (running on CPU 8) now connects GRP0:0 to GRP1:0, updates
parent pointer of GRP0:0 and ...
[GRP1:0]
migrator = TMIGR_NONE
active = 0x00
nextevt = KTIME_MAX
/ \
[GRP0:0] [GRP0:1]
migrator = 0x01 migrator = TMIGR_NONE
active = 0x01 active = 0x00
nextevt = KTIME_MAX nextevt = KTIME_MAX
childmask= 0 childmask= 1
parent = GRP1:0 parent = GRP1:0
/ \
0 1 .. 7 8
active idle !online
childmask=1
tmigr_walk.childmask = 0
3) ... CPU 0 comes active in the same time. As migrator in GRP0:0 was
TMIGR_NONE, childmask of GRP0:0 is stored in update propagation data
structure tmigr_walk (as update of childmask is not yet
visible/updated). And now ...
[GRP1:0]
migrator = TMIGR_NONE
active = 0x00
nextevt = KTIME_MAX
/ \
[GRP0:0] [GRP0:1]
migrator = 0x01 migrator = TMIGR_NONE
active = 0x01 active = 0x00
nextevt = KTIME_MAX nextevt = KTIME_MAX
childmask= 2 childmask= 1
parent = GRP1:0 parent = GRP1:0
/ \
0 1 .. 7 8
active idle !online
childmask=1
tmigr_walk.childmask = 0
4) ... childmask of GRP0:0 is updated by CPU 8 (still part of setup
code).
[GRP1:0]
migrator = 0x00
active = 0x00
nextevt = KTIME_MAX
/ \
[GRP0:0] [GRP0:1]
migrator = 0x01 migrator = TMIGR_NONE
active = 0x01 active = 0x00
nextevt = KTIME_MAX nextevt = KTIME_MAX
childmask= 2 childmask= 1
parent = GRP1:0 parent = GRP1:0
/ \
0 1 .. 7 8
active idle !online
childmask=1
tmigr_walk.childmask = 0
5) CPU 0 sees the connection to GRP1:0 and now propagates active state to
GRP1:0 but with childmask = 0 as stored in propagation data structure.
--> Now GRP1:0 always has a migrator as 0x00 != TMIGR_NONE and for all CPUs
it looks like GRP1:0 is always active.
To prevent those races, the setup of the hierarchy is moved into the
cpuhotplug prepare callback. The prepare callback is not executed by the
CPU which will come online, it is executed by the CPU which prepares
onlining of the other CPU. This CPU is active while it is connecting the
formerly top level to the new one. This prevents from (A) to happen and it
also prevents from any further walk above the formerly top level until that
active CPU becomes inactive, releasing the new ->parent and ->childmask
updates to be visible by any subsequent walk up above the formerly top
level hierarchy. This prevents from (B) to happen. The direction for the
updates is now forced to look like "from bottom to top".
However if the active CPU prevents from tmigr_cpu_(in)active() to walk up
with the update not-or-half visible, nothing prevents walking up to the new
top with a 0 childmask in tmigr_handle_remote_up() or
tmigr_requires_handle_remote_up() if the active CPU doing the prepare is
not the migrator. But then it looks fine because:
* tmigr_check_migrator() should just return false
* The migrator is active and should eventually observe the new childmask
at some point in a future tick.
Split setup functionality of online callback into the cpuhotplug prepare
callback and setup hotplug state. Change init call into early_initcall() to
make sure an already active CPU prepares everything for newly upcoming
CPUs. Reorder the code, that all prepare related functions are close to
each other and online and offline callbacks are also close together.

timers/migration: Do not rely always on group->parent
When reading group->parent without holding the group lock it is racy
against CPUs coming online the first time and thereby creating another
level of the hierarchy. This is not a problem when this value is read once
to decide whether to abort a propagation or not. The worst outcome is an
unnecessary/early CPU wake up. But it is racy when reading it several times
during a single 'action' (like activation, deactivation, checking for
remote timer expiry,...) and relying on the consitency of this value
without holding the lock. This happens at the moment e.g. in
tmigr_inactive_up() which is also calling tmigr_udpate_events(). Code relys
on group->parent not to change during this 'action'.
Update parent struct member description to explain the above only
once. Remove parent pointer checks when they are not mandatory (like update
of data->childmask). Remove a warning, which would be nice but the trigger
of this warning is not reliable and add expand the data structure member
description instead. Expand a comment, why it is safe to rely on parent
pointer here (inside hierarchy update).

ata: ahci: Clean up sysfs file on error
.probe() (ahci_init_one()) calls sysfs_add_file_to_group(), however,
if probe() fails after this call, we currently never call
sysfs_remove_file_from_group().
(The sysfs_remove_file_from_group() call in .remove() (ahci_remove_one())
does not help, as .remove() is not called on .probe() error.)
Thus, if probe() fails after the sysfs_add_file_to_group() call, the next
time we insmod the module we will get:

libsas is currently not freeing all the struct ata_port struct members,
e.g. ncq_sense_buf for a driver supporting Command Duration Limits (CDL).
Add a function, ata_port_free(), that is used to free a ata_port,
including its struct members. It makes sense to keep the code related to
freeing a ata_port in its own function, which will also free all the
struct members of struct ata_port.

TTY/Serial/Console fixes for 6.10-rc6
Here are a bunch of fixes/reverts for 6.10-rc6. Include in here are:
- revert the bunch of tty/serial/console changes that landed in -rc1
that didn't quite work properly yet. Everyone agreed to just revert
them for now and will work on making them better for a future
release instead of trying to quick fix the existing changes this
late in the release cycle
- 8250 driver port count bugfix
- Other tiny serial port bugfixes for reported issues
All of these have been in linux-next this week with no reported issues.

Bug fixes for 6.10-rc6:
* Always free only post-EOF delayed allocations for files with the
XFS_DIFLAG_PREALLOC or APPEND flags set.
* Do not align cow fork delalloc to cowextsz hint when running low on space.
* Allow zero-size symlinks and directories as long as the link count is
zero.
* Change XFS_IOC_EXCHANGE_RANGE to be a _IOW only ioctl. This was ioctl was
introduced during v6.10 developement cycle.
* xfs_init_new_inode() now creates an attribute fork on a newly created
inode even if ATTR feature flag is not enabled.

x86: stop playing stack games in profile_pc()
The 'profile_pc()' function is used for timer-based profiling, which isn't really all that relevant any more to begin with, but it also ends up making assumptions based on the stack layout that aren't necessarily valid. Basically, the code tries to account the time spent in spinlocks to the caller rather than the spinlock, and while I support that as a concept, it's not worth the code complexity or the KASAN warnings when no serious profiling is done using timers anyway these days. And the code really does depend on stack layout that is only true in the simplest of cases. We've lost the comment at some point (I think when the 32-bit and 64-bit code was unified), but it used to say: Assume the lock function has either no stack frame or a copy of eflags from PUSHF. which explains why it just blindly loads a word or two straight off the stack pointer and then takes a minimal look at the values to just check if they might be eflags or the return pc: Eflags always has bits 22 and up cleared unlike kernel addresses but that basic stack layout assumption assumes that there isn't any lock debugging etc going on that would complicate the code and cause a stack frame. It causes KASAN unhappiness reported for years by syzkaller [1] and others [2]. With no real practical reason for this any more, just remove the code. Just for historical interest, here's some background commits relating to this code from 2006: |

i2c: testunit: discard write requests while old command is running
When clearing registers on new write requests was added, the protection
for currently running commands was missed leading to concurrent access
to the testunit registers. Check the flag beforehand.

i2c: testunit: don't erase registers after STOP
STOP fallsthrough to WRITE_REQUESTED but this became problematic when
clearing the testunit registers was added to the latter. Actually, there
is no reason to clear the testunit state after STOP. Doing it when a new
WRITE_REQUESTED arrives is enough. So, no need to fallthrough, at all.

bcachefs fixes for 6.10-rc6
simple stuff: - null ptr/err ptr deref fixes - fix for getting wedged on shutdown after journal error - fix missing recalc_capacity() call, capacity now changes correctly after a device goes read only however: our capacity calculation still doesn't take into account when we have mixed ro/rw devices and the ro devices have data on them, that's going to be a more involved fix to separate accounting for "capacity used on ro devices" and "capacity used on rw devices" - boring syzbot stuff slightly more involved: - discard, invalidate workers are now per device this has the effect of simplifying how we take device refs in these paths, and the device ref cleanup fixes a longstanding race between the device removal path and the discard path - fixes for how the debugfs code takes refs on btree_trans objects we have debugfs code that prints in use btree_trans objects. It uses closure_get() on trans->ref, which is mainly for the cycle detector, but the debugfs code was using it on a closure that may have hit 0, which is not allowed; for performance reasons we cannot avoid having not-in-use transactions on the global list. introduce some new primitives to fix this and make the synchronization here a whole lot saner -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKnAFLkS8Qha+jvQrE6szbY3KbnYFAmZ+ye4ACgkQE6szbY3K bnb4shAAqkKdgB2abIaD1t8+KjUiXwt7seRY4EmzwrEaWniW5bDUYMBvV+tew93j uvGmSKMs4ML/r24hcg0zGPJ9GoWrFb3MWhPYizzRS8QspsUjsECJuehNPCe3RPaf QBgQtKahTge1e41y1frzkiGKqaOGOTtUVLOfPIebe+oJAhRCYRnrGY2dkZTms7Ue aXNtBmnlX3Fkmlm0GiKYrTHpAZz3d0kzdX11Pc2vTXvqo/znuJTTVGnjJkdrHzyv 6cz6YnMKFdxLVbYO1KlB/3Hu9y9qt815g1rjvaqym8pDk9ltsGHNM3LcCCCyp7Of btnbLQ6TdfggK5Kf2hNYuJRY2pnjNyfcNxupQF3RNaw/D/4G5EU16zfFElORC6Mw eGwXLvDIGqOSSIvevoRZrgJKAvVptXNg9EtCI5Z5ujQ4ExW8ti1lPHp/r5SVOhyz x0Am14H2ERuz7Vt5jUas3k74+tAck6JWc5OemMQawA5waeH1inMT7QZuBt+Bmrhx Av0zbhaq4aTsHXmm+Xi6ofj3UBaOQ2rNzT7Au0kxdvJgDPe/USjw4tejV5DmjmHA SyRsTG7Zn5xJBi7jc47fcwUgUzlxlffVQGFCVjRUU1vF6u/Ldn7K0zfYbkwSCiKp iWSEyg3j5z5N69Vrgdadma4xTDjL/C5+XsMWh8G8ohf+crhUeSo= =svIi -----END PGP SIGNATURE----- Merge tag 'bcachefs-2024-06-28' of https://evilpiepirate.org/git/bcachefs Pull bcachefs fixes from Kent Overstreet: "Simple stuff: - NULL ptr/err ptr deref fixes - fix for getting wedged on shutdown after journal error - fix missing recalc_capacity() call, capacity now changes correctly after a device goes read only however: our capacity calculation still doesn't take into account when we have mixed ro/rw devices and the ro devices have data on them, that's going to be a more involved fix to separate accounting for "capacity used on ro devices" and "capacity used on rw devices" - boring syzbot stuff Slightly more involved: - discard, invalidate workers are now per device this has the effect of simplifying how we take device refs in these paths, and the device ref cleanup fixes a longstanding race between the device removal path and the discard path - fixes for how the debugfs code takes refs on btree_trans objects we have debugfs code that prints in use btree_trans objects.

tty: mxser: Remove __counted_by from mxser_board.ports[]
Work for __counted_by on generic pointers in structures (not just
flexible array members) has started landing in Clang 19 (current tip of
tree). During the development of this feature, a restriction was added
to __counted_by to prevent the flexible array member's element type from
including a flexible array member itself such as:
struct foo {
int count;
char buf[];
};
struct bar {
int count;
struct foo data[] __counted_by(count);
};
because the size of data cannot be calculated with the standard array
size formula:
sizeof(struct foo) * count
This restriction was downgraded to a warning but due to CONFIG_WERROR,
it can still break the build. The application of __counted_by on the
ports member of 'struct mxser_board' triggers this restriction,
resulting in:
drivers/tty/mxser.c:291:2: error: 'counted_by' should not be applied to an array with element of unknown size because 'struct mxser_port' is a struct type with a flexible array member. This will be an error in a future compiler version [-Werror,-Wbounds-safety-counted-by-elt-type-unknown-size]
291 | struct mxser_port ports[] __counted_by(nports);
| ^~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
Remove this use of __counted_by to fix the warning/error. However,
rather than remove it altogether, leave it commented, as it may be
possible to support this in future compiler releases.

ata: libata-core: Add ATA_HORKAGE_NOLPM for all Crucial BX SSD1 models
We got another report that CT1000BX500SSD1 does not work with LPM.
If you look in libata-core.c, we have six different Crucial devices that
are marked with ATA_HORKAGE_NOLPM. This model would have been the seventh.
(This quirk is used on Crucial models starting with both CT* and
Crucial_CT*)
It is obvious that this vendor does not have a great history of supporting
LPM properly, therefore, add the ATA_HORKAGE_NOLPM quirk for all Crucial
BX SSD1 models.

tools/power turbostat: option '-n' is ambiguous
In some cases specifying the '-n' command line argument will cause
turbostat to fail. For instance 'turbostat -n 1' works fine; however,
'turbostat -n 1 -d' will fail. This is the result of the first call
to getopt_long_only() where "MP" is specified as the optstring. This can
be easily fixed by changing the optstring from "MP" to "MPn:" to remove
ambiguity between the arguments.
tools/power turbostat: option '-n' is ambiguous; possibilities: '-num_iterations' '-no-msr' '-no-perf'

drm/drm_file: Fix pid refcounting race
<maarten.lankhorst@linux.intel.com>, Maxime Ripard
<mripard@kernel.org>, Thomas Zimmermann <tzimmermann@suse.de>
filp->pid is supposed to be a refcounted pointer; however, before this
patch, drm_file_update_pid() only increments the refcount of a struct
pid after storing a pointer to it in filp->pid and dropping the
dev->filelist_mutex, making the following race possible:
process A process B
========= =========
begin drm_file_update_pid
mutex_lock(&dev->filelist_mutex)
rcu_replace_pointer(filp->pid, <pid B>, 1)
mutex_unlock(&dev->filelist_mutex)
begin drm_file_update_pid
mutex_lock(&dev->filelist_mutex)
rcu_replace_pointer(filp->pid, <pid A>, 1)
mutex_unlock(&dev->filelist_mutex)
get_pid(<pid A>)
synchronize_rcu()
put_pid(<pid B>) *** pid B reaches refcount 0 and is freed here ***
get_pid(<pid B>) *** UAF ***
synchronize_rcu()
put_pid(<pid A>)
As far as I know, this race can only occur with CONFIG_PREEMPT_RCU=y
because it requires RCU to detect a quiescent state in code that is not
explicitly calling into the scheduler.
This race leads to use-after-free of a "struct pid".
It is probably somewhat hard to hit because process A has to pass
through a synchronize_rcu() operation while process B is between
mutex_unlock() and get_pid().
Fix it by ensuring that by the time a pointer to the current task's pid
is stored in the file, an extra reference to the pid has been taken.
This fix also removes the condition for synchronize_rcu(); I think
that optimization is unnecessary complexity, since in that case we
would usually have bailed out on the lockless check above.
