mm: introduce memfd_secret system call to create "secret" memory areas
Introduce "memfd_secret" system call with the ability to create memory
areas visible only in the context of the owning process and not mapped not
only to other processes but in the kernel page tables as well.
The secretmem feature is off by default and the user must explicitly
enable it at the boot time.
Once secretmem is enabled, the user will be able to create a file
descriptor using the memfd_secret() system call. The memory areas created
by mmap() calls from this file descriptor will be unmapped from the kernel
direct map and they will be only mapped in the page table of the processes
that have access to the file descriptor.
Secretmem is designed to provide the following protections:
* Enhanced protection (in conjunction with all the other in-kernel
attack prevention systems) against ROP attacks. Seceretmem makes
"simple" ROP insufficient to perform exfiltration, which increases the
required complexity of the attack. Along with other protections like
the kernel stack size limit and address space layout randomization which
make finding gadgets is really hard, absence of any in-kernel primitive
for accessing secret memory means the one gadget ROP attack can't work.
Since the only way to access secret memory is to reconstruct the missing
mapping entry, the attacker has to recover the physical page and insert
a PTE pointing to it in the kernel and then retrieve the contents. That
takes at least three gadgets which is a level of difficulty beyond most
standard attacks.
* Prevent cross-process secret userspace memory exposures. Once the
secret memory is allocated, the user can't accidentally pass it into the
kernel to be transmitted somewhere. The secreremem pages cannot be
accessed via the direct map and they are disallowed in GUP.
* Harden against exploited kernel flaws. In order to access secretmem,
a kernel-side attack would need to either walk the page tables and
create new ones, or spawn a new privileged uiserspace process to perform
secrets exfiltration using ptrace.
The file descriptor based memory has several advantages over the
"traditional" mm interfaces, such as mlock(), mprotect(), madvise(). File
descriptor approach allows explicit and controlled sharing of the memory
areas, it allows to seal the operations. Besides, file descriptor based
memory paves the way for VMMs to remove the secret memory range from the
userspace hipervisor process, for instance QEMU. Andy Lutomirski says:
"Getting fd-backed memory into a guest will take some possibly major
work in the kernel, but getting vma-backed memory into a guest without
mapping it in the host user address space seems much, much worse."
memfd_secret() is made a dedicated system call rather than an extension to
memfd_create() because it's purpose is to allow the user to create more
secure memory mappings rather than to simply allow file based access to
the memory. Nowadays a new system call cost is negligible while it is way
simpler for userspace to deal with a clear-cut system calls than with a
multiplexer or an overloaded syscall. Moreover, the initial
implementation of memfd_secret() is completely distinct from
memfd_create() so there is no much sense in overloading memfd_create() to
begin with. If there will be a need for code sharing between these
implementation it can be easily achieved without a need to adjust user
visible APIs.
The secret memory remains accessible in the process context using uaccess
primitives, but it is not exposed to the kernel otherwise; secret memory
areas are removed from the direct map and functions in the
follow_page()/get_user_page() family will refuse to return a page that
belongs to the secret memory area.
Once there will be a use case that will require exposing secretmem to the
kernel it will be an opt-in request in the system call flags so that user
would have to decide what data can be exposed to the kernel.
Removing of the pages from the direct map may cause its fragmentation on
architectures that use large pages to map the physical memory which
affects the system performance. However, the original Kconfig text for
CONFIG_DIRECT_GBPAGES said that gigabyte pages in the direct map "... can
improve the kernel's performance a tiny bit ..." (commit

set_memory: allow querying whether set_direct_map_*() is actually enabled
On arm64, set_direct_map_*() functions may return 0 without actually changing the linear map. This behaviour can be controlled using kernel parameters, so we need a way to determine at runtime whether calls to set_direct_map_invalid_noflush() and set_direct_map_default_noflush() have any effect. Extend set_memory API with can_set_direct_map() function that allows checking if calling set_direct_map_*() will actually change the page table, replace several occurrences of open coded checks in arm64 with the new function and provide a generic stub for architectures that always modify page tables upon calls to set_direct_map APIs.

mmap: make mlock_future_check() global
Patch series "mm: introduce memfd_secret system call to create "secret" memory areas", v20.
This is an implementation of "secret" mappings backed by a file
descriptor.
The file descriptor backing secret memory mappings is created using a
dedicated memfd_secret system call The desired protection mode for the
memory is configured using flags parameter of the system call. The mmap()
of the file descriptor created with memfd_secret() will create a "secret"
memory mapping. The pages in that mapping will be marked as not present
in the direct map and will be present only in the page table of the owning
mm.
Although normally Linux userspace mappings are protected from other users,
such secret mappings are useful for environments where a hostile tenant is
trying to trick the kernel into giving them access to other tenants
mappings.
It's designed to provide the following protections:
* Enhanced protection (in conjunction with all the other in-kernel
attack prevention systems) against ROP attacks. Seceretmem makes
"simple" ROP insufficient to perform exfiltration, which increases the
required complexity of the attack. Along with other protections like
the kernel stack size limit and address space layout randomization which
make finding gadgets is really hard, absence of any in-kernel primitive
for accessing secret memory means the one gadget ROP attack can't work.
Since the only way to access secret memory is to reconstruct the missing
mapping entry, the attacker has to recover the physical page and insert
a PTE pointing to it in the kernel and then retrieve the contents. That
takes at least three gadgets which is a level of difficulty beyond most
standard attacks.
* Prevent cross-process secret userspace memory exposures. Once the
secret memory is allocated, the user can't accidentally pass it into the
kernel to be transmitted somewhere. The secreremem pages cannot be
accessed via the direct map and they are disallowed in GUP.
* Harden against exploited kernel flaws. In order to access secretmem,
a kernel-side attack would need to either walk the page tables and
create new ones, or spawn a new privileged uiserspace process to perform
secrets exfiltration using ptrace.
In the future the secret mappings may be used as a mean to protect guest
memory in a virtual machine host.
For demonstration of secret memory usage we've created a userspace library
https://git.kernel.org/pub/scm/linux/kernel/git/jejb/secret-memory-preloader.git
that does two things: the first is act as a preloader for openssl to
redirect all the OPENSSL_malloc calls to secret memory meaning any secret
keys get automatically protected this way and the other thing it does is
expose the API to the user who needs it. We anticipate that a lot of the
use cases would be like the openssl one: many toolkits that deal with
secret keys already have special handling for the memory to try to give
them greater protection, so this would simply be pluggable into the
toolkits without any need for user application modification.
Hiding secret memory mappings behind an anonymous file allows usage of the
page cache for tracking pages allocated for the "secret" mappings as well
as using address_space_operations for e.g. page migration callbacks.
The anonymous file may be also used implicitly, like hugetlb files, to
implement mmap(MAP_SECRET) and use the secret memory areas with "native"
mm ABIs in the future.
Removing of the pages from the direct map may cause its fragmentation on
architectures that use large pages to map the physical memory which
affects the system performance. However, the original Kconfig text for
CONFIG_DIRECT_GBPAGES said that gigabyte pages in the direct map "... can

mm/slub: use stackdepot to save stack trace in objects
Many stack traces are similar so there are many similar arrays. Stackdepot saves each unique stack only once. Replace field addrs in struct track with depot_stack_handle_t handle. Use stackdepot to save stack trace. The benefits are smaller memory overhead and possibility to aggregate per-cache statistics in the future using the stackdepot handle instead of matching stacks manually.

hexagon: handle {,SOFT}IRQENTRY_TEXT in linker script
Patch series "hexagon: Fix build error with CONFIG_STACKDEPOT and select CONFIG_ARCH_WANT_LD_ORPHAN_WARN". This series fixes an error with ARCH=hexagon that was pointed out by the patch "mm/slub: use stackdepot to save stack trace in objects". The first patch fixes that error by handling the '.irqentry.text' and '.softirqentry.text' sections. The second patch switches Hexagon over to the common DISCARDS macro, which should have been done when Hexagon was merged into the tree to match commit |

Fixes and improvements for FPU handling on x86:
- Prevent sigaltstack out of bounds writes. The kernel unconditionally
writes the FPU state to the alternate stack without checking whether
the stack is large enough to accomodate it.
Check the alternate stack size before doing so and in case it's too
small force a SIGSEGV instead of silently corrupting user space data.
- MINSIGSTKZ and SIGSTKSZ are constants in signal.h and have never been
updated despite the fact that the FPU state which is stored on the
signal stack has grown over time which causes trouble in the field
when AVX512 is available on a CPU. The kernel does not expose the
minimum requirements for the alternate stack size depending on the
available and enabled CPU features.
ARM already added an aux vector AT_MINSIGSTKSZ for the same reason.
Add it to x86 as well
- A major cleanup of the x86 FPU code. The recent discoveries of XSTATE
related issues unearthed quite some inconsistencies, duplicated code
and other issues.
The fine granular overhaul addresses this, makes the code more robust
and maintainable, which allows to integrate upcoming XSTATE related
features in sane ways.

More fallthrough fixes for Clang for 5.14-rc1
Hi Linus,
Please, pull the following patches that fix many fall-through warnings
when building with Clang 12.0.0 and this[1] change reverted. Notice
that in order to enable -Wimplicit-fallthrough for Clang, such change[1]
is meant to be reverted at some point. So, these patches help to move
in that direction.
Thanks!

gpio: updates for v5.14
- new driver for the IDT 79RC3243x GPIO controller
- device tree bindings coversion to YAML for the following drivers:
gpio-rk3328-grf, gpio-omap, gpio-davinci, gpio-zynq, gpio-stp, gpio-pcf857x
- cleanup of probe functions in many drivers from Alexandru Ardelean, mostly
dropping unnecessary calls to platform_set_drvdata() and removing error
messages where none are needed (handled by the subsystem already)
- several improvements to the core gpiolib and the sysfs interface code from
Andy Shevchenko
- conversion of the gpio-xilinx driver to using the bitmap API + improvements
of suspend/resume handling + minor tweaks
- convert the gpio-stmpe to using devres helpers exclusively in probe for
improved robustness
- updates for the generic gpio-regmap driver
- updates for the gpio-dwapb driver
- support for a new model in gpio-pca953x
- cleanups in gpio-tegra186, gpio-104-idio-16, gpio-mxs & gpio-xgene
- slight code refactoring of the gpio-zynq driver
- documentation fixes from Mauro Carvalho Chehab
- a bunch of minor tweaks and improvements all over the place

Merge tag 'gpio-updates-for-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"One new driver, support for new models in existing ones, dt-bindings
conversions for several modules and improvements all over the place.
Summary:
- new driver for the IDT 79RC3243x GPIO controller
- device tree bindings coversion to YAML for the following drivers:
gpio-rk3328-grf, gpio-omap, gpio-davinci, gpio-zynq, gpio-stp,
gpio-pcf857x
- cleanup of probe functions in many drivers from Alexandru Ardelean,
mostly dropping unnecessary calls to platform_set_drvdata() and
removing error messages where none are needed (handled by the
subsystem already)
- several improvements to the core gpiolib and the sysfs interface
code from Andy Shevchenko
- conversion of the gpio-xilinx driver to using the bitmap API +
improvements of suspend/resume handling + minor tweaks
- convert the gpio-stmpe to using devres helpers exclusively in probe
for improved robustness
- updates for the generic gpio-regmap driver
- updates for the gpio-dwapb driver
- support for a new model in gpio-pca953x
- cleanups in gpio-tegra186, gpio-104-idio-16, gpio-mxs & gpio-xgene
- slight code refactoring of the gpio-zynq driver
- documentation fixes from Mauro Carvalho Chehab
- a bunch of minor tweaks and improvements all over the place"
