x86/bugs: Rename CONFIG_GDS_FORCE_MITIGATION => CONFIG_MITIGATION_GDS_FORCE
So the CPU mitigations Kconfig entries - there's 10 meanwhile - are named in a historically idiosyncratic and hence rather inconsistent fashion and have become hard to relate with each other over the years: https://lore.kernel.org/lkml/20231011044252.42bplzjsam3qsasz@treble/ When they were introduced we never expected that we'd eventually have about a dozen of them, and that more organization would be useful, especially for Linux distributions that want to enable them in an informed fashion, and want to make sure all mitigations are configured as expected. For example, the current CONFIG_SPECULATION_MITIGATIONS namespace is only halfway populated, where some mitigations have entries in Kconfig, and they could be modified, while others mitigations do not have Kconfig entries, and can not be controlled at build time. Fine-grained control over these Kconfig entries can help in a number of ways: 1) Users can choose and pick only mitigations that are important for their workloads. 2) Users and developers can choose to disable mitigations that mangle the assembly code generation, making it hard to read. 3) Separate Kconfigs for just source code readability, so that we see *which* butt-ugly piece of crap code is for what reason... In most cases, if a mitigation is disabled at compilation time, it can still be enabled at runtime using kernel command line arguments. This is the first patch of an initial series that renames various mitigation related Kconfig options, unifying them under a single CONFIG_MITIGATION_* namespace: CONFIG_GDS_FORCE_MITIGATION => CONFIG_MITIGATION_GDS_FORCE CONFIG_CPU_IBPB_ENTRY => CONFIG_MITIGATION_IBPB_ENTRY CONFIG_CALL_DEPTH_TRACKING => CONFIG_MITIGATION_CALL_DEPTH_TRACKING CONFIG_PAGE_TABLE_ISOLATION => CONFIG_MITIGATION_PAGE_TABLE_ISOLATION CONFIG_RETPOLINE => CONFIG_MITIGATION_RETPOLINE CONFIG_SLS => CONFIG_MITIGATION_SLS CONFIG_CPU_UNRET_ENTRY => CONFIG_MITIGATION_UNRET_ENTRY CONFIG_CPU_IBRS_ENTRY => CONFIG_MITIGATION_IBRS_ENTRY CONFIG_CPU_SRSO => CONFIG_MITIGATION_SRSO CONFIG_RETHUNK => CONFIG_MITIGATION_RETHUNK Implement step 1/10 of the namespace unification of CPU mitigations related Kconfig options and rename CONFIG_GDS_FORCE_MITIGATION to CONFIG_MITIGATION_GDS_FORCE.

linux_kselftest-kunit-6.8-rc1
This KUnit update for Linux 6.8-rc1 consists of:
- a new feature that adds APIs for managing devices introducing
a set of helper functions which allow devices (internally a
struct kunit_device) to be created and managed by KUnit.
These devices will be automatically unregistered on
test exit. These helpers can either use a user-provided
struct device_driver, or have one automatically created and
managed by KUnit. In both cases, the device lives on a new
kunit_bus.
- changes to switch drm/tests to use kunit devices
- several fixes and enhancements to attribute feature
- changes to reorganize deferred action function introducing
KUNIT_DEFINE_ACTION_WRAPPER
- new feature adds ability to run tests after boot using debugfs
- fixes and enhancements to string-stream-test:
- parse ERR_PTR in string_stream_destroy()
- unchecked dereference in bug fix in debugfs_print_results()
- handling errors from alloc_string_stream()
- NULL-dereference bug fix in kunit_init_suite()

Pull power management updates from Rafael Wysocki:
"These add support for new processors (Sierra Forest, Grand Ridge and
Meteor Lake) to the intel_idle driver, make intel_pstate run on
Emerald Rapids without HWP support and adjust it to utilize EPP values
supplied by the platform firmware, fix issues, clean up code and
improve documentation.
The most significant fix addresses deadlocks in the core system-wide
resume code that occur if async_schedule_dev() attempts to run its
argument function synchronously (for example, due to a memory
allocation failure). It rearranges the code in question which may
increase the system resume time in some cases, but this basically is a
removal of a premature optimization. That optimization will be added
back later, but properly this time.

Pull thermal control updates from Rafael Wysocki:
"These add support for the D1/T113s THS controller to the sun8i driver
and a DT-based mechanism for platforms to indicate a preference to
reboot (instead of shutting down) on crossing a critical trip point,
fix issues, make other improvements (in the IPA governor, the Intel
HFI driver, the exynos driver and the thermal netlink interface among
other places) and clean up code.
One long-standing issue addressed here is that trip point crossing
notifications sent to user space might be unreliable due to the
incorrect handling of trip point hysteresis in the thermal core:
multiple notifications might be sent for the same event or there might
be events without any notification at all.

Pull ACPI updates from Rafael Wysocki:
"From the new features standpoint, the most significant change here is
the addition of CSI-2 and MIPI DisCo for Imaging support to the ACPI
device enumeration code that will allow MIPI cameras to be enumerated
through the platform firmware on systems using ACPI.
Also significant is the switch-over to threaded interrupt handlers for
the ACPI SCI and the dedicated EC interrupt (on systems where the
former is not used) which essentially allows all ACPI code to run with
local interrupts enabled. That should improve responsiveness
significantly on systems where multiple GPEs are enabled and the
handling of one SCI involves many I/O address space accesses which
previously had to be carried out in one go with disabled interrupts on
the local CPU.
Apart from the above, the ACPI thermal zone driver will use the
Thermal fast Sampling Period (_TFP) object if available, which should
allow temperature changes to be followed more accurately on some
systems, the ACPI Notify () handlers can run on all CPUs (not just on
CPU0), which should generally speed up the processing of events
signaled through the ACPI SCI, and the ACPI power button driver will
trigger wakeup key events via the input subsystem (on systems where it
is a system wakeup device)
In addition to that, there are the usual bunch of fixes and cleanups.
Specifics:
- Add CSI-2 and DisCo for Imaging support to the ACPI device
enumeration code (Sakari Ailus, Rafael J. Wysocki)
- Adjust the cpufreq thermal reduction algorithm in the ACPI
processor driver for Tegra241 (Srikar Srimath Tirumala, Arnd
Bergmann)
- Make acpi_proc_quirk_mwait_check() x86-specific (Rafael J. Wysocki)
- Switch over ACPI to using a threaded interrupt handler for the SCI
(Rafael J. Wysocki)
- Allow ACPI Notify () handlers to run on all CPUs and clean up the
ACPI interface for deferred events processing (Rafael J. Wysocki)
- Switch over the ACPI EC driver to using a threaded handler for the
dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki)
- Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock
to keep local interrupts on (Rafael J. Wysocki)
- Adjust the USB4 _OSC handshake to correctly handle cases in which
certain types of OS control are denied by the platform (Mika
Westerberg)
- Correct and clean up the generic function for parsing ACPI
data-only tables with array structure (Yuntao Wang)
- Modify acpi_dev_uid_match() to support different types of its
second argument and adjust its users accordingly (Raag Jadav)
- Clean up code related to acpi_evaluate_reference() and ACPI device
lists (Rafael J. Wysocki)
- Use generic ACPI helpers for evaluating trip point temperature
objects in the ACPI thermal zone driver (Rafael J. Wysockii, Arnd
Bergmann)
- Add Thermal fast Sampling Period (_TFP) support to the ACPI thermal
zone driver (Jeff Brasen)
- Modify the ACPI LPIT table handling code to avoid u32
multiplication overflows in state residency computations (Nikita
Kiryushin)
- Drop an unused helper function from the ACPI backlight (video)
driver and add a clarifying comment to it (Hans de Goede)
- Update the ACPI backlight driver to avoid using uninitialized
memory in some cases (Nikita Kiryushin)
- Add ACPI backlight quirk for the Colorful X15 AT 23 laptop (Yuluo
Qiu)
- Add support for vendor-defined error types to the ACPI APEI error
injection code (Avadhut Naik)
- Adjust APEI to properly set MF_ACTION_REQUIRED on synchronous
memory failure events, so they are handled differently from the
asynchronous ones (Shuai Xue)
- Fix NULL pointer dereference check in the ACPI extlog driver
(Prarit Bhargava)
- Adjust the ACPI extlog driver to clear the Extended Error Log
status when RAS_CEC handled the error (Tony Luck)
- Add IRQ override quirks for some Infinity laptops and for TongFang
GMxXGxx (David McFarland, Hans de Goede)
- Clean up the ACPI NUMA code and fix it to ensure that fake_pxm is
not the same as one of the real pxm values (Yuntao Wang)
- Fix the fractional clock divider flags in the ACPI LPSS (Intel SoC)
driver so as to prevent miscalculation of the values in the clock
divider (Andy Shevchenko)
- Adjust comments in the ACPI watchdog driver to prevent kernel-doc
from complaining during documentation builds (Randy Dunlap)
- Make the ACPI button driver send wakeup key events to user space in
addition to power button events on systems that can be woken up by
the power button (Ken Xue)
- Adjust pnpacpi_parse_allocated_vendor() to use memcpy() on a full
structure field (Dmitry Antipov)"

* MTD
Apart from preventing the mtdblk to run on top of ftl or ubiblk (which
may cause security issues and has no meaning anyway), there are a few
misc fixes.
* Raw NAND
Two meaningful changes this time. The conversion of the brcmnand driver
to the ->exec_op() API, this series brought additional changes to the
core in order to help controller drivers to handle themselves the WP pin
during destructive operations when relevant.
There is also a series bringing important fixes to the sequential read
feature.
As always, there is as well a whole bunch of miscellaneous W=1 fixes,
together with a few runtime fixes (double free, timeout value, OOB
layout, missing register initialization) and the usual load of remove
callbacks turned into void (which led to switch the txx9ndfmc driver to
use module_platform_driver()).
* SPI NOR
SPI NOR comes with die erase support for multi die flashes, with new
octal protocols (1-1-8 and 1-8-8) parsed from SFDP and with an updated
documentation about what the contributors shall consider when proposing
flash additions or updates.
Michael Walle stepped out from the reviewer role to maintainer.

regulator: Updates for v6.8
The main updates for this release are around monitoring of regulators,
largely for error handling purposes. We allow the stream of regulator
events to be seen by userspace as netlink events and allow system
integrators to describe individual regulators as system critical with
information on how long the system is expected to last on error. The
system level error handling is very much about best effort problem
mitigation rather than providing something fully robust, the initial
drive was to provide a mechanism for trying to avoid initiating any new
writes to flash once we notice the power going out.
Otherwise it's very quiet, mainly several new Qualcomm devices.
- Support for marking regulators as system critical and providing
information on how long the system might last with those regulators
in a failure state, hooked into the existing critical shutdown error
handling.
- Optional support for generating netlink events for events, there are
use cases for system monitoring UIs and error handling.
- A command line option to leave unused controllable regulators
enabled, useful for debugging. We already only disable regulators we
were explicitly given permission to control.
- Support for Quacomm MP5496, PM8010 and PM8937.

The first syscall simply lists the LSMs enabled, while the second and third get and set the current process' LSM attributes. Yes, these syscalls may provide similar functionality to what can be found under /proc or /sys, but they were designed to support multiple, simultaneaous (stacked) LSMs from the start as opposed to the current /proc based solutions which were created at a time when only one LSM was allowed to be active at a given time. We have spent considerable time discussing ways to extend the existing /proc interfaces to support multiple, simultaneaous LSMs and even our best ideas have been far too ugly to support as a kernel API; after +20 years in the kernel, I felt the LSM layer had established itself enough to justify a handful of syscalls. Support amongst the individual LSM developers has been nearly unanimous, with a single objection coming from Tetsuo (TOMOYO) as he is worried that the LSM_ID_XXX token concept will make it more difficult for out-of-tree LSMs to survive. Several members of the LSM community have demonstrated the ability for out-of-tree LSMs to continue to exist by picking high/unused LSM_ID values as well as pointing out that many kernel APIs rely on integer identifiers, e.g. syscalls (!), but unfortunately Tetsuo's objections remain. My personal opinion is that while I have no interest in penalizing out-of-tree LSMs, I'm not going to penalize in-tree development to support out-of-tree development, and I view this as a necessary step forward to support the push for expanded LSM stacking and reduce our reliance on /proc and /sys which has occassionally been problematic for some container users. Finally, we have included the linux-api folks on (all?) recent revisions of the patchset and addressed all of their concerns. - Add a new security_file_ioctl_compat() LSM hook to handle the 32-bit ioctls on 64-bit systems problem. This patch includes support for all of the existing LSMs which provide ioctl hooks, although it turns out only SELinux actually cares about the individual ioctls. It is worth noting that while Casey (Smack) and Tetsuo (TOMOYO) did not give explicit ACKs to this patch, they did both indicate they are okay with the changes. - Fix a potential memory leak in the CALIPSO code when IPv6 is disabled at boot. While it's good that we are fixing this, I doubt this is something users are seeing in the wild as you need to both disable IPv6 and then attempt to configure IPv6 labeled networking via NetLabel/CALIPSO; that just doesn't make much sense. Normally this would go through netdev, but Jakub asked me to take this patch and of all the trees I maintain, the LSM tree seemed like the best fit. - Update the LSM MAINTAINERS entry with additional information about our process docs, patchwork, bug reporting, etc. I also noticed that the Lockdown LSM is missing a dedicated MAINTAINERS entry so I've added that to the pull request. I've been working with one of the major Lockdown authors/contributors to see if they are willing to step up and assume a Lockdown maintainer role; hopefully that will happen soon, but in the meantime I'll continue to look after it. - Add a handful of mailmap entries for Serge Hallyn and myself. * tag 'lsm-pr-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: (27 commits) lsm: new security_file_ioctl_compat() hook lsm: Add a __counted_by() annotation to lsm_ctx.ctx calipso: fix memory leak in netlbl_calipso_add_pass() selftests: remove the LSM_ID_IMA check in lsm/lsm_list_modules_test MAINTAINERS: add an entry for the lockdown LSM MAINTAINERS: update the LSM entry mailmap: add entries for Serge Hallyn's dead accounts mailmap: update/replace my old email addresses lsm: mark the lsm_id variables are marked as static lsm: convert security_setselfattr() to use memdup_user() lsm: align based on pointer length in lsm_fill_user_ctx() lsm: consolidate buffer size handling into lsm_fill_user_ctx() lsm: correct error codes in security_getselfattr() lsm: cleanup the size counters in security_getselfattr() lsm: don't yet account for IMA in LSM_CONFIG_COUNT calculation lsm: drop LSM_ID_IMA LSM: selftests for Linux Security Module syscalls SELinux: Add selfattr hooks AppArmor: Add selfattr hooks Smack: implement setselfattr and getselfattr hooks ... |

Prior to this patch all processes were marked as SECINITSID_KERNEL before the SELinux policy was loaded, making it difficult to distinquish early boot userspace processes from the kernel in the SELinux policy. For most users this will be a non-issue as the policy is loaded early enough during boot, but for users who load their SELinux policy relatively late, this should make it easier to construct meaningful security policies. - Cleanups to the selinuxfs code by Al, mostly on VFS related issues during a policy reload. The commit description has more detail, but the quick summary is that we are replacing a disconnected directory approach with a temporary directory that we swapover at the end of the reload. - Fix an issue where the input sanity checking on socket bind() operations was slightly different depending on the presence of SELinux. This is caused by the placement of the LSM hooks in the generic socket layer as opposed to the protocol specific bind() handler where the protocol specific sanity checks are performed. Mickaël has mentioned that he is working to fix this, but in the meantime we just ensure that we are replicating the checks properly. We need to balance the placement of the LSM hooks with the number of LSM hooks; pushing the hooks down into the protocol layers is likely not the right answer. - Update the avc_has_perm_noaudit() prototype to better match the function definition. - Migrate from using partial_name_hash() to full_name_hash() the filename transition hash table. This improves the quality of the code and has the potential for a minor performance bump. - Consolidate some open coded SELinux access vector comparisions into a single new function, avtab_node_cmp(), and use that instead. A small, but nice win for code quality and maintainability. - Updated the SELinux MAINTAINERS entry with additional information around process, bug reporting, etc. We're also updating some of our "official" roles: dropping Eric Paris and adding Ondrej as a reviewer. - Cleanup the coding style crimes in security/selinux/include. While I'm not a fan of code churn, I am pushing for more automated code checks that can be done at the developer level and one of the obvious things to check for is coding style. In an effort to start from a "good" base I'm slowly working through our source files cleaning them up with the help of clang-format and good ol' fashioned human eyeballs; this has the first batch of these changes. I've been splitting the changes up per-file to help reduce the impact if backports are required (either for LTS or distro kernels), and I expect the some of the larger files, e.g. hooks.c and ss/services.c, will likely need to be split even further. - Cleanup old, outdated comments. * tag 'selinux-pr-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: (24 commits) selinux: Fix error priority for bind with AF_UNSPEC on PF_INET6 socket selinux: fix style issues in security/selinux/include/initial_sid_to_string.h selinux: fix style issues in security/selinux/include/xfrm.h selinux: fix style issues in security/selinux/include/security.h selinux: fix style issues with security/selinux/include/policycap_names.h selinux: fix style issues in security/selinux/include/policycap.h selinux: fix style issues in security/selinux/include/objsec.h selinux: fix style issues with security/selinux/include/netlabel.h selinux: fix style issues in security/selinux/include/netif.h selinux: fix style issues in security/selinux/include/ima.h selinux: fix style issues in security/selinux/include/conditional.h selinux: fix style issues in security/selinux/include/classmap.h selinux: fix style issues in security/selinux/include/avc_ss.h selinux: align avc_has_perm_noaudit() prototype with definition selinux: fix style issues in security/selinux/include/avc.h selinux: fix style issues in security/selinux/include/audit.h MAINTAINERS: drop Eric Paris from his SELinux role MAINTAINERS: add Ondrej Mosnacek as a SELinux reviewer selinux: remove the wrong comment about multithreaded process handling selinux: introduce an initial SID for early boot processes ... |

Pull audit updates from Paul Moore:
"The audit updates are fairly minor with only two patches:
- Send an audit ACK to userspace immediately upon receiving an auditd
registration event as opposed to waiting until the registration has
been fully processed and the audit backlog starts filling the
netlink buffers.
Sending the ACK earlier, as done here, is still safe as the
operation should not fail at the point when the ACK is done, and
doing so helps avoid the ACK being dropped in extreme situations.
- Update the audit MAINTAINERS entry with additional information.
There isn't anything in this update that should be new to regular
contributors or list subscribers, but I'm pushing to start
documenting our processes, conventions, etc. and this seems like an
important part of that"

exclusive for a particular CPU. Chengming noticed that we use it also
in situations where we are not yet installing the slab as the CPU
slab, because freezing also indicates that the slab is not on the
shared list. This results in redundant freeze/unfreeze operation and
can be avoided by marking separately the shared list presence by
reusing the PG_workingset flag.
This approach neatly avoids the issues described in

cgroup: Changes for v6.8
- Yafang Shao added task_get_cgroup1() helper to enable a similar BPF helper so that BPF progs can be more useful on cgroup1 hierarchies. While cgroup1 is mostly in maintenance mode, this addition is very small while having an outsized usefulness for users who are still on cgroup1. Yafang also optimized root cgroup list access by making it RCU protected in the process. - Waiman Long optimized rstat operation leading to substantially lower and more consistent lock hold time while flushing the hierarchical statistics. As the lock can be acquired briefly in various hot paths, this reduction has cascading benefits. - Waiman also improved the quality of isolation for cpuset's isolated partitions. CPUs which are allocated to isolated partitions are now excluded from running unbound work items and cpu_is_isolated() test which is used by vmstat and memcg to reduce interference now includes cpuset isolated CPUs. While it isn't there yet, the hope is eventually reaching parity with the isolation level provided by the `isolcpus` boot param but in a dynamic manner. This involved a couple workqueue patches which were applied directly to cgroup/for-6.8 rather than ping-ponged through the wq tree. This was because the wq code change was small and the area is usually very static and unlikely to cause conflicts. However, luck had it that there was a wq bug fix in the area during the 6.7 cycle which caused a conflict. The conflict is contextual but can be a bit confusing to resolve, so there is one merge from wq/for-6.7-fixes. -----BEGIN PGP SIGNATURE----- iIQEABYKACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCZYnuJg4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGQ5kAP9nMMWqi+R1HeG7+hWROTVjQZ0OM9KRcpZ1TmjF FNbkJgEAzt+sPnoWwYDTSI7pkNeZ/IM7x1qkkKGvENNtUXrz0Ac= =PyYN -----END PGP SIGNATURE----- Merge tag 'cgroup-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup Pull cgroup updates from Tejun Heo: - Yafang Shao added task_get_cgroup1() helper to enable a similar BPF helper so that BPF progs can be more useful on cgroup1 hierarchies.

Scheduler changes for v6.8:
- Energy scheduling:
- Consolidate how the max compute capacity is
used in the scheduler and how we calculate
the frequency for a level of utilization.
- Rework interface between the scheduler and
the schedutil governor
- Simplify the util_est logic
- Deadline scheduler:
- Work more towards reducing SCHED_DEADLINE
starvation of low priority tasks (e.g., SCHED_OTHER)
tasks when higher priority tasks monopolize CPU
cycles, via the introduction of 'deadline servers'
(nested/2-level scheduling).
"Fair servers" to make use of this facility are
not introduced yet.
- EEVDF:
- Introduce O(1) fastpath for EEVDF task selection
- NUMA balancing:
- Tune the NUMA-balancing vma scanning logic some more,
to better distribute the probability
of a particular vma getting scanned.
- Plus misc fixes, cleanups and updates.

Debugobject changes for v6.8:
- Make tracking object use more robust: it's not safe to access a
tracking object after releasing the hashbucket lock. Create a
persistent copy for debug printouts instead.
