fscrypt updates for 5.10
This release, we rework the implementation of creating new encrypted files in order to fix some deadlocks and prepare for adding fscrypt support to CephFS, which Jeff Layton is working on. We also export a symbol in preparation for the above-mentioned CephFS support and also for ext4/f2fs encrypt+casefold support. Finally, there are a few other small cleanups. As usual, all these patches have been in linux-next with no reported issues, and I've tested them with xfstests. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQSacvsUNc7UX4ntmEPzXCl4vpKOKwUCX4SD7xQcZWJpZ2dlcnNA Z29vZ2xlLmNvbQAKCRDzXCl4vpKOKy/AAP92oOybTcuahmvAtHqZP9jAFPJrbI3r 6QLpMFtWznJoOQEAogaWsavtOIBx9afdOfRNj0zdoBIjpXgyMuzR10Ou2gE= =B/Mj -----END PGP SIGNATURE----- Merge tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt Pull fscrypt updates from Eric Biggers: "This release, we rework the implementation of creating new encrypted files in order to fix some deadlocks and prepare for adding fscrypt support to CephFS, which Jeff Layton is working on.

perf build: Allow nested externs to enable BUILD_BUG() usage
Currently the BUILD_BUG() macro is expanded to the following:
do {
extern void __compiletime_assert_0(void)
__attribute__((error("BUILD_BUG failed")));
if (!(!(1)))
__compiletime_assert_0();
} while (0);
If used in a function body this would obviously produce build errors
with -Wnested-externs and -Werror.
To enable BUILD_BUG() usage in tools/arch/x86/lib/insn.c which perf
includes in intel-pt-decoder, build perf without -Wnested-externs.

x86/uaccess: utilize CONFIG_CC_HAS_ASM_GOTO_OUTPUT
Clang-11 shipped support for outputs to asm goto statments along the fallthrough path. Double up some of the get_user() and related macros to be able to take advantage of this extended GNU C extension. This should help improve the generated code's performance for these accesses.

x86: Make __put_user() generate an out-of-line call
Instead of inlining the stac/mov/clac sequence (which also requires individual exception table entries and several asm instruction alternatives entries), just generate "call __put_user_nocheck_X" for the __put_user() cases, the same way we changed __get_user earlier. Unlike the get_user() case, we didn't have the same nice infrastructure to just generate the call with a single case, so this actually has to change some of the infrastructure in order to do this. But that only cleans up the code further. So now, instead of using a case statement for the sizes, we just do the same thing we've done on the get_user() side for a long time: use the size as an immediate constant to the asm, and generate the asm that way directly. In order to handle the special case of 64-bit data on a 32-bit kernel, I needed to change the calling convention slightly: the data is passed in %eax[:%edx], the pointer in %ecx, and the return value is also returned in %ecx. It used to be returned in %eax, but because of how %eax can now be a double register input, we don't want mix that with a single-register output. The actual low-level asm is easier to handle: we'll just share the code between the checking and non-checking case, with the non-checking case jumping into the middle of the function. That may sound a bit too special, but this code is all very very special anyway, so...

x86: Make __get_user() generate an out-of-line call
Instead of inlining the whole stac/lfence/mov/clac sequence (which also requires individual exception table entries and several asm instruction alternatives entries), just generate "call __get_user_nocheck_X" for the __get_user() cases. We can use all the same infrastructure that we already do for the regular "get_user()", and the end result is simpler source code, and much simpler code generation. It also means that when I introduce asm goto with input for "unsafe_get_user()", there are no nasty interactions with the __get_user() code.

overflow: Add __must_check attribute to check_*() helpers
Since the destination variable of the check_*_overflow() helpers will contain a wrapped value on failure, it would be best to make sure callers really did check the return result of the helper. Adjust the macros to use a bool-wrapping static inline that is marked with __must_check. This means the macros can continue to have their type-agnostic behavior while gaining the function attribute (that cannot be applied directly to macros).

This tree introduces static_call(), which is the idea of static_branch()
applied to indirect function calls. Remove a data load (indirection) by
modifying the text.
They give the flexibility of function pointers, but with better
performance. (This is especially important for cases where
retpolines would otherwise be used, as retpolines can be pretty
slow.)
API overview:
DECLARE_STATIC_CALL(name, func);
DEFINE_STATIC_CALL(name, func);
DEFINE_STATIC_CALL_NULL(name, typename);
static_call(name)(args...);
static_call_cond(name)(args...);
static_call_update(name, func);
x86 is supported via text patching, otherwise basic indirect calls are used,
with function pointers.
There's a second variant using inline code patching, inspired by jump-labels,
implemented on x86 as well.
The new APIs are utilized in the x86 perf code, a heavy user of function pointers,
where static calls speed up the PMU handler by 4.2% (!).
The generic implementation is not really excercised on other architectures,
outside of the trivial test_static_call_init() self-test.

Pull static call support from Ingo Molnar:
"This introduces static_call(), which is the idea of static_branch()
applied to indirect function calls. Remove a data load (indirection)
by modifying the text.
They give the flexibility of function pointers, but with better
performance. (This is especially important for cases where retpolines
would otherwise be used, as retpolines can be pretty slow.)
API overview:
DECLARE_STATIC_CALL(name, func);
DEFINE_STATIC_CALL(name, func);
DEFINE_STATIC_CALL_NULL(name, typename);
static_call(name)(args...);
static_call_cond(name)(args...);
static_call_update(name, func);
x86 is supported via text patching, otherwise basic indirect calls are
used, with function pointers.
There's a second variant using inline code patching, inspired by
jump-labels, implemented on x86 as well.
The new APIs are utilized in the x86 perf code, a heavy user of
function pointers, where static calls speed up the PMU handler by
4.2% (!).
The generic implementation is not really excercised on other
architectures, outside of the trivial test_static_call_init()
self-test"

Orphan link sections were a long-standing source of obscure bugs,
because the heuristics that various linkers & compilers use to handle them (include these bits into the output image vs discarding them silently) are both highly idiosyncratic and also version dependent. Instead of this historically problematic mess, this tree by Kees Cook (et al) adds build time asserts and build time warnings if there's any orphan section in the kernel or if a section is not sized as expected. And because we relied on so many silent assumptions in this area, fix a metric ton of dependencies and some outright bugs related to this, before we can finally enable the checks on the x86, ARM and ARM64 platforms.

EFI changes for v5.10:
- Preliminary RISC-V enablement - the bulk of it will arrive via the RISCV tree.
- Relax decompressed image placement rules for 32-bit ARM
- Add support for passing MOK certificate table contents via a config table
rather than a EFI variable.
- Add support for 18 bit DIMM row IDs in the CPER records.
- Work around broken Dell firmware that passes the entire Boot#### variable
contents as the command line
- Add definition of the EFI_MEMORY_CPU_CRYPTO memory attribute so we can
identify it in the memory map listings.
- Don't abort the boot on arm64 if the EFI RNG protocol is available but
returns with an error
- Replace slashes with exclamation marks in efivarfs file names
- Split efi-pstore from the deprecated efivars sysfs code, so we can
disable the latter on !x86.
- Misc fixes, cleanups and updates.

These are the locking updates for v5.10:
- Add deadlock detection for recursive read-locks. The rationale is outlined
in:
224ec489d3cd: ("lockdep/Documention: Recursive read lock detection reasoning")
The main deadlock pattern we want to detect is:
TASK A: TASK B:
read_lock(X);
write_lock(X);
read_lock_2(X);
- Add "latch sequence counters" (seqcount_latch_t):
A sequence counter variant where the counter even/odd value is used to
switch between two copies of protected data. This allows the read path,
typically NMIs, to safely interrupt the write side critical section.
We utilize this new variant for sched-clock, and to make x86 TSC handling safer.
- Other seqlock cleanups, fixes and enhancements
- KCSAN updates
- LKMM updates
- Misc updates, cleanups and fixes.

Surgery of the MSI interrupt handling to prepare the support of upcoming
devices which require non-PCI based MSI handling.
- Cleanup historical leftovers all over the place
- Rework the code to utilize more core functionality
- Wrap XEN PCI/MSI interrupts into an irqdomain to make irqdomain
assignment to PCI devices possible.
- Assign irqdomains to PCI devices at initialization time which allows
to utilize the full functionality of hierarchical irqdomains.
- Remove arch_.*_msi_irq() functions from X86 and utilize the irqdomain
which is assigned to the device for interrupt management.
- Make the arch_.*_msi_irq() support conditional on a config switch and
let the last few users select it.

Pull x86 irq updates from Thomas Gleixner:
"Surgery of the MSI interrupt handling to prepare the support of
upcoming devices which require non-PCI based MSI handling:
- Cleanup historical leftovers all over the place
- Rework the code to utilize more core functionality
- Wrap XEN PCI/MSI interrupts into an irqdomain to make irqdomain
assignment to PCI devices possible.
- Assign irqdomains to PCI devices at initialization time which
allows to utilize the full functionality of hierarchical
irqdomains.
- Remove arch_.*_msi_irq() functions from X86 and utilize the
irqdomain which is assigned to the device for interrupt management.
- Make the arch_.*_msi_irq() support conditional on a config switch
and let the last few users select it"

Updates for the interrupt subsystem:
Core:
- Allow trimming of interrupt hierarchy to support odd hardware setups
where only a subset of the interrupts requires the full hierarchy.
- Allow the retrigger mechanism to follow a hierarchy to simplify
driver code.
- Provide a mechanism to force enable wakeup interrrupts on suspend.
- More infrastructure to handle IPIs in the core code
Architectures:
- Convert ARM/ARM64 IPI handling to utilize the interrupt core code.
Drivers:
- The usual pile of new interrupt chips (MStar, Actions Owl, TI PRUSS,
Designware ICTL)
- ARM(64) IPI related conversions
- Wakeup support for Qualcom PDC
- Prevent hierarchy corruption in the NVIDIA Tegra driver
- The usual small fixes, improvements and cleanups all over the place.

Updates for timekeeping, timers and related drivers:
Core:
- Early boot support for the NMI safe timekeeper by utilizing
local_clock() up to the point where timekeeping is initialized. This
allows printk() to store multiple timestamps in the ringbuffer which is
useful for coordinating dmesg information across a fleet of machines.
- Provide a multi-timestamp accessor for printk()
- Make timer init more robust by checking for invalid timer flags.
- Comma vs. semicolon fixes
Drivers:
- Support for new platforms in existing drivers (SP804 and Renesas CMT)
- Comma vs. semicolon fixes
