Merge tag 'landlock_v34' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull Landlock LSM from James Morris:
"Add Landlock, a new LSM from Mickaël Salaün.
Briefly, Landlock provides for unprivileged application sandboxing.
From Mickaël's cover letter:
"The goal of Landlock is to enable to restrict ambient rights (e.g.
global filesystem access) for a set of processes. Because Landlock
is a stackable LSM [1], it makes possible to create safe security
sandboxes as new security layers in addition to the existing
system-wide access-controls. This kind of sandbox is expected to
help mitigate the security impact of bugs or unexpected/malicious
behaviors in user-space applications. Landlock empowers any
process, including unprivileged ones, to securely restrict
themselves.
Landlock is inspired by seccomp-bpf but instead of filtering
syscalls and their raw arguments, a Landlock rule can restrict the
use of kernel objects like file hierarchies, according to the
kernel semantic. Landlock also takes inspiration from other OS
sandbox mechanisms: XNU Sandbox, FreeBSD Capsicum or OpenBSD
Pledge/Unveil.
In this current form, Landlock misses some access-control features.
This enables to minimize this patch series and ease review. This
series still addresses multiple use cases, especially with the
combined use of seccomp-bpf: applications with built-in sandboxing,
init systems, security sandbox tools and security-oriented APIs [2]"
The cover letter and v34 posting is here:
https://lore.kernel.org/linux-security-module/20210422154123.13086-1-mic@digikod.net/

This code has had extensive design discussion and review over several
years"

afs: Fix speculative status fetches
The generic/464 xfstest causes kAFS to emit occasional warnings of the
form:
kAFS: vnode modified {100055:8a} 30->31 YFS.StoreData64 (c=6015)
This indicates that the data version received back from the server did not
match the expected value (the DV should be incremented monotonically for
each individual modification op committed to a vnode).
What is happening is that a lookup call is doing a bulk status fetch
speculatively on a bunch of vnodes in a directory besides getting the
status of the vnode it's actually interested in. This is racing with a
StoreData operation (though it could also occur with, say, a MakeDir op).
On the client, a modification operation locks the vnode, but the bulk
status fetch only locks the parent directory, so no ordering is imposed
there (thereby avoiding an avenue to deadlock).
On the server, the StoreData op handler doesn't lock the vnode until it's
received all the request data, and downgrades the lock after committing the
data until it has finished sending change notifications to other clients -
which allows the status fetch to occur before it has finished.
This means that:
- a status fetch can access the target vnode either side of the exclusive
section of the modification
- the status fetch could start before the modification, yet finish after,
and vice-versa.
- the status fetch and the modification RPCs can complete in either order.
- the status fetch can return either the before or the after DV from the
modification.
- the status fetch might regress the locally cached DV.
Some of these are handled by the previous fix[1], but that's not sufficient
because it checks the DV it received against the DV it cached at the start
of the op, but the DV might've been updated in the meantime by a locally
generated modification op.
Fix this by the following means:
(1) Keep track of when we're performing a modification operation on a
vnode. This is done by marking vnode parameters with a 'modification'
note that causes the AFS_VNODE_MODIFYING flag to be set on the vnode
for the duration.
(2) Alter the speculation race detection to ignore speculative status
fetches if either the vnode is marked as being modified or the data
version number is not what we expected.
Note that whilst the "vnode modified" warning does get recovered from as it
causes the client to refetch the status at the next opportunity, it will
also invalidate the pagecache, so changes might get lost.
Fixes:

- Extend DM ioctl's DM_LIST_DEVICES_CMD handling to include UUID and
allow filtering based on name or UUID prefix.
- Various small fixes for typos, warnings, unused function, or
needlessly exported interfaces.

- Fix request-based DM's double free of blk_mq_tag_set in device remove
after table load fails.
- Improve DM persistent data performance on non-x86 by fixing packed
structs to have a stated alignment. Also remove needless extra work
from redundant calls to sm_disk_get_nr_free() and a paranoid BUG_ON()
that caused duplicate checksum calculation.
- Fix missing goto in DM integrity's bitmap_flush_interval error
handling.
- Add "reset_recalculate" feature flag to DM integrity.
- Improve DM integrity by leveraging discard support to avoid needless
re-writing of metadata and also use discard support to improve hash
recalculation.
- Fix race with DM raid target's reshape and MD raid4/5/6 resync that
resulted in inconsistant reshape state during table reloads.
- Update DM raid target to temove unnecessary discard limits for raid0
and raid10 now that MD has optimized discard handling for both raid
levels.

Merge tag 'iommu-updates-v5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel:
- Big cleanup of almost unsused parts of the IOMMU API by Christoph
Hellwig. This mostly affects the Freescale PAMU driver.
- New IOMMU driver for Unisoc SOCs
- ARM SMMU Updates from Will:
- Drop vestigial PREFETCH_ADDR support (SMMUv3)
- Elide TLB sync logic for empty gather (SMMUv3)
- Fix "Service Failure Mode" handling (SMMUv3)
- New Qualcomm compatible string (SMMUv2)
- Removal of the AMD IOMMU performance counter writeable check on AMD.
It caused long boot delays on some machines and is only needed to
work around an errata on some older (possibly pre-production) chips.
If someone is still hit by this hardware issue anyway the performance
counters will just return 0.
- Support for targeted invalidations in the AMD IOMMU driver. Before
that the driver only invalidated a single 4k page or the whole IO/TLB
for an address space. This has been extended now and is mostly useful
for emulated AMD IOMMUs.
- Several fixes for the Shared Virtual Memory support in the Intel VT-d
driver
- Mediatek drivers can now be built as modules
- Re-introduction of the forcedac boot option which got lost when
converting the Intel VT-d driver to the common dma-iommu
implementation.
- Extension of the IOMMU device registration interface and support
iommu_ops to be const again when drivers are built as modules.

"There is a lot going on!
Core changes:
- A semantic change to handle pinmux and pinconf in explicit order
while up until now we depended on the semantic order in the device
tree. The device tree is a functional programming language and does
not imply any order, so the right thing is for the pin control core
to provide these semantics.
- Add a new pinmux-select debugfs file which makes it possible to go
in and select functions for a pin manually (iteratively, at the
prompt) for debugging purposes.
- Fixes to gpio regmap handling for a new pin control driver making
use of regmap-gpio.
- Use octal permissions on debugfs files.
New drivers:
- A massive rewrite of the former custom pin control driver for MIPS
Broadcom devices to instead use the pin control subsystem. New pin
control drivers for BCM6345, BCM6328, BCM6358, BCM6362, BCM6368,
BCM63268 and BCM6318 SoC variants are implemented.
- Support for PM8350, PM8350B, PM8350C, PMK8350, PMR735A and PMR735B
in the Qualcomm PMIC GPIO driver. Also the two GPIOs on PM8008 are
supported.
- Support for the Rockchip RK3568/RK3566 pin controller.
- Support for Ingenic JZ4730, JZ4750, JZ4755, JZ4775 and X2000.
- Support for Mediatek MTK8195.
- Add a new Xilinx ZynqMP pin control driver.
Driver improvements and non-urgent fixes:
- Modularization and improvements of the Rockchip drivers.
- Some new pins added to the description of new Renesas SoCs.
- Clarifications of the GPIO base calculation in the Intel driver.
- Fix the function names for the MPP54 and MPP55 pins in the Armada
CP110 pin controller.
- GPIO wakeup interrupt map for Qualcomm SC7280 and SM8350.
- Support for ACPI probing of the Qualcomm SC8180x.
- Fix interrupt clear status on rockchip
- Fix some missing pins on the Ingenic JZ4770, some semantic fixes
for the behaviour of the Ingenic pin controller. Add DMIC pins for
JZ4780, X1000, X1500 and X1830.

Merge tag 'sound-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"No surprises in this development cycle, and most of work is about the
fixes and the improvements of the existing code, while a new LED
control layer and a few new drivers have been introduced.
Here are some highlights:
Core:
- A common mute-LED framework was introduced. It is used by HD-audio
for now, more adaption will follow later. The former "Mic Mute-LED
Mode" mixer control has been replaced with the corresponding sysfs
now.
- User-control management was changed to count consumed bytes instead
of capping by number of elements; this will allow more controls in
the normal usage pattern while avoiding the possible memory
exhaustion DoS
ASoC:
- Continued refactoring and cleanups in ASoC core and generic card
drivers
- Wide range of small cppcheck and warning fixes
- New drivers for Freescale i.MX DMA over rpmsg, Mediatek MT6358
accessory detection, and Realtek RT1019, RT1316, RT711 and RT715
USB-audio:
- Continued improvements and fixes of the implicit feedback mode,
including better support for Pioneer and Roland/BOSS devices
HD-audio:
- Default back to non-buffer preallocation on x86
- Cirrus codec improvements, more quirks for Realtek codecs
Others:
- New virtio sound driver
- FireWire Bebob updates"

Merge tag 'modules-for-v5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux
Pull module updates from Jessica Yu:
"Fix an age old bug involving jump_calls and static_labels when
CONFIG_MODULE_UNLOAD=n.
When CONFIG_MODULE_UNLOAD=n, it means you can't unload modules, so
normally the __exit sections of a module are not loaded at all.
However, dynamic code patching (jump_label, static_call, alternatives)
can have sites in __exit sections even if __exit is never executed.
Reported by Peter Zijlstra:
'Alternatives, jump_labels and static_call all can have relocations
into __exit code. Not loading it at all would be BAD.'
Therefore, load the __exit sections even when CONFIG_MODULE_UNLOAD=n,
and discard them after init"

mm/memory-failure: unnecessary amount of unmapping
It appears that unmap_mapping_range() actually takes a 'size' as its third
argument rather than a location, the current calling fashion causes
unnecessary amount of unmapping to occur.

mm: page_alloc: ignore init_on_free=1 for debug_pagealloc=1
On !ARCH_SUPPORTS_DEBUG_PAGEALLOC (like ia64) debug_pagealloc=1 implies
page_poison=on:
if (page_poisoning_enabled() ||
(!IS_ENABLED(CONFIG_ARCH_SUPPORTS_DEBUG_PAGEALLOC) &&
debug_pagealloc_enabled()))
static_branch_enable(&_page_poisoning_enabled);
page_poison=on needs to override init_on_free=1.
Before the change it did not work as expected for the following case:
- have PAGE_POISONING=y
- have page_poison unset
- have !ARCH_SUPPORTS_DEBUG_PAGEALLOC arch (like ia64)
- have init_on_free=1
- have debug_pagealloc=1
That way we get both keys enabled:
- static_branch_enable(&init_on_free);
- static_branch_enable(&_page_poisoning_enabled);
which leads to poisoned pages returned for __GFP_ZERO pages.
After the change we execute only:
- static_branch_enable(&_page_poisoning_enabled);
and ignore init_on_free=1.
