arm64: extable: use ex for exception_table_entry
Subsequent patches will extend `struct exception_table_entry` with more fields, and the distinction between the entry and its `fixup` field will become more important. For clarity, let's consistently use `ex` to refer to refer to an entire entry. In subsequent patches we'll use `fixup` to refer to the fixup field specifically. This matches the naming convention used today in arch/arm64/net/bpf_jit_comp.c. There should be no functional change as a result of this patch.

arm64: extable: make fixup_exception() return bool
The return values of fixup_exception() and arm64_bpf_fixup_exception() represent a boolean condition rather than an error code, so for clarity it would be better to return `bool` rather than `int`. This patch adjusts the code accordingly. While we're modifying the prototype, we also remove the unnecessary `extern` keyword, so that this won't look out of place when we make subsequent additions to the header. There should be no functional change as a result of this patch.

arm64: extable: consolidate definitions
In subsequent patches we'll alter the structure and usage of struct exception_table_entry. For inline assembly, we create these using the `_ASM_EXTABLE()` CPP macro defined in <asm/uaccess.h>, and for plain assembly code we use the `_asm_extable()` GAS macro defined in <asm/assembler.h>, which are largely identical save for different escaping and stringification requirements. This patch moves the common definitions to a new <asm/asm-extable.h> header, so that it's easier to keep the two in-sync, and to remove the implication that these are only used for uaccess helpers (as e.g. load_unaligned_zeropad() is only used on kernel memory, and depends upon `_ASM_EXTABLE()`. At the same time, a few minor modifications are made for clarity and in preparation for subsequent patches: * The structure creation is factored out into an `__ASM_EXTABLE_RAW()` macro. This will make it easier to support different fixup variants in subsequent patches without needing to update all users of `_ASM_EXTABLE()`, and makes it easier to see tha the CPP and GAS variants of the macros are structurally identical. For the CPP macro, the stringification of fields is left to the wrapper macro, `_ASM_EXTABLE()`, as in subsequent patches it will be necessary to stringify fields in wrapper macros to safely concatenate strings which cannot be token-pasted together in CPP. * The fields of the structure are created separately on their own lines. This will make it easier to add/remove/modify individual fields clearly. * Additional parentheses are added around the use of macro arguments in field definitions to avoid any potential problems with evaluation due to operator precedence, and to make errors upon misuse clearer. * USER() is moved into <asm/asm-uaccess.h>, as it is not required by all assembly code, and is already refered to by comments in that file. There should be no functional change as a result of this patch.

arm64: factor out GPR numbering helpers
In <asm/sysreg.h> we have macros to convert the names of general purpose registers (GPRs) into integer constants, which we use to manually build the encoding for `MRS` and `MSR` instructions where we can't rely on the assembler to do so for us. In subsequent patches we'll need to map the same GPR names to integer constants so that we can use this to build metadata for exception fixups. So that the we can use the mappings elsewhere, factor out the definitions into a new <asm/gpr-num.h> header, renaming the definitions to align with this "GPR num" naming for clarity.

arm64: lib: __arch_copy_to_user(): fold fixups into body
Like other functions, __arch_copy_to_user() places its exception fixups in the `.fixup` section without any clear association with __arch_copy_to_user() itself. If we backtrace the fixup code, it will be symbolized as an offset from the nearest prior symbol, which happens to be `__entry_tramp_text_end`. Further, since the PC adjustment for the fixup is akin to a direct branch rather than a function call, __arch_copy_to_user() itself will be missing from the backtrace. This is confusing and hinders debugging. In general this pattern will also be problematic for CONFIG_LIVEPATCH, since fixups often return to their associated function, but this isn't accurately captured in the stacktrace. To solve these issues for assembly functions, we must move fixups into the body of the functions themselves, after the usual fast-path returns. This patch does so for __arch_copy_to_user(). Inline assembly will be dealt with in subsequent patches. Other than the improved backtracing, there should be no functional change as a result of this patch.

arm64 fixes:
- It turns out that the optimised string routines merged in 5.14 are not
safe with in-kernel MTE (KASAN_HW_TAGS) because of reading beyond the
end of a string (strcmp, strncmp). Such reading may go across a 16
byte tag granule and cause a tag check fault. When KASAN_HW_TAGS is
enabled, use the generic strcmp/strncmp C implementation.
- An errata workaround for ThunderX relied on the CPU capabilities being
enabled in a specific order. This disappeared with the automatic
generation of the cpucaps.h file (sorted alphabetically). Fix it by
checking the current CPU only rather than the system-wide capability.
- Add system_supports_mte() checks on the kernel entry/exit path and
thread switching to avoid unnecessary barriers and function calls on
systems where MTE is not supported.
- kselftests: skip arm64 tests if the required features are missing.

Invoke rseq_handle_notify_resume() from tracehook_notify_resume() now
that the two function are always called back-to-back by architectures

don't support rseq, i.e. this is a nop across the board.

arm64: Mitigate MTE issues with str{n}cmp()
As with strlen(), the patches importing the updated str{n}cmp()
implementations were originally developed and tested before the
advent of CONFIG_KASAN_HW_TAGS, and have subsequently revealed
not to be MTE-safe. Since in-kernel MTE is still a rather niche
case, let it temporarily fall back to the generic C versions for
correctness until we can figure out the best fix.

arm64: add MTE supported check to thread switching and syscall entry/exit
This lets us avoid doing unnecessary work on hardware that does not
support MTE, and will allow us to freely use MTE instructions in the
code called by mte_thread_switch().
Since this would mean that we do a redundant check in
mte_check_tfsr_el1(), remove it and add two checks now required in its
callers. This also avoids an unnecessary DSB+ISB sequence on the syscall
exit path for hardware not supporting MTE.

__stack_chk_guard is setup once while init stage and never changed after that.

arm64/sve: Use correct size when reinitialising SVE state
When we need a buffer for SVE register state we call sve_alloc() to make
sure that one is there. In order to avoid repeated allocations and frees
we keep the buffer around unless we change vector length and just memset()
it to ensure a clean register state. The function that deals with this
takes the task to operate on as an argument, however in the case where we
do a memset() we initialise using the SVE state size for the current task
rather than the task passed as an argument.
This is only an issue in the case where we are setting the register state
for a task via ptrace and the task being configured has a different vector
length to the task tracing it. In the case where the buffer is larger in
the traced process we will leak old state from the traced process to
itself, in the case where the buffer is smaller in the traced process we
will overflow the buffer and corrupt memory.

arm64: dts: qcom: ipq8074: remove USB tx-fifo-resize property
tx-fifo-resize is now added by default by the dwc3-qcom driver
to the SNPS DWC3 child node.
So, lets drop the tx-fifo-resize property from dwc3-qcom nodes
as having it there will cause the dwc3-qcom driver to error and
abort probe with:
[ 1.362938] dwc3-qcom 8af8800.usb: unable to add property
[ 1.368405] dwc3-qcom 8af8800.usb: failed to register DWC3 Core, err=-17

Merge branch 'gcc-min-version-5.1' (make gcc-5.1 the minimum version)
Merge patch series from Nick Desaulniers to update the minimum gcc version to 5.1. This is some of the left-overs from the merge window that I didn't want to deal with yesterday, so it comes in after -rc1 but was sent before. Gcc-4.9 support has been an annoyance for some time, and with -Werror I had the choice of applying a fairly big patch from Kees Cook to remove a fair number of initializer warnings (still leaving some), or this patch series from Nick that just removes the source of the problem. The initializer cleanups might still be worth it regardless, but honestly, I preferred just tackling the problem with gcc-4.9 head-on. We've been more aggressiuve about no longer having to care about compilers that were released a long time ago, and I think it's been a good thing. I added a couple of patches on top to sort out a few left-overs now that we no longer support gcc-4.x. As noted by Arnd, as a result of this minimum compiler version upgrade we can probably change our use of '--std=gnu89' to '--std=gnu11', and finally start using local loop declarations etc. But this series does _not_ yet do that.

arm64: mm: limit linear region to 51 bits for KVM in nVHE mode
KVM in nVHE mode divides up its VA space into two equal halves, and picks the half that does not conflict with the HYP ID map to map its linear region. This worked fine when the kernel's linear map itself was guaranteed to cover precisely as many bits of VA space, but this was changed by commit |

KVM: stats: Add VM stat for remote tlb flush requests
Add a new stat that counts the number of times a remote TLB flush is requested, regardless of whether it kicks vCPUs out of guest mode. This allows us to look at how often flushes are initiated. Unlike remote_tlb_flush, this one applies to ARM's instruction-set-based TLB flush implementation, so apply it there too.

memblock: make memblock_find_in_range method private
There are a lot of uses of memblock_find_in_range() along with memblock_reserve() from the times memblock allocation APIs did not exist. memblock_find_in_range() is the very core of memblock allocations, so any future changes to its internal behaviour would mandate updates of all the users outside memblock. Replace the calls to memblock_find_in_range() with an equivalent calls to memblock_phys_alloc() and memblock_phys_alloc_range() and make memblock_find_in_range() private method of memblock. This simplifies the callers, ensures that (unlikely) errors in memblock_reserve() are handled and improves maintainability of memblock_find_in_range().

ARM: SoC updates for 5.15
There are three noteworthy updates for 32-bit arm platforms this time:
- The Microchip SAMA7 family based on Cortex-A7 gets introduced, a new
cousin to the older SAM9 (ARM9xx based) and SAMA5 (Cortex-A5 based)
SoCs.
- The ixp4xx platform (based on Intel XScale) is finally converted to
device tree, and all the old board files are getting removed now.
- The Cirrus Logic EP93xx platform loses support for the old
MaverickCrunch FPU. Support for compiling user space applications
was already removed in gcc-4.9, and the kernel support for old
applications could not be built with clang ias. After confirming
that there are no remaining users, removing this from the kernel
seemed better than adding support for unused features to clang.
There are minor updates to the aspeed, omap and samsung platforms

asm-generic changes for 5.15
The main content for 5.15 is a series that cleans up the handling of
strncpy_from_user() and strnlen_user(), removing a lot of slightly
incorrect versions of these in favor of the lib/strn*.c helpers
that implement these correctly and more efficiently.
The only architectures that retain a private version now are
mips, ia64, um and parisc. I had offered to convert those at all,
but Thomas Bogendoerfer wanted to keep the mips version for the
moment until he had a chance to do regression testing.
The branch also contains two patches for bitops and for ffs().

- Support for 32-bit tasks on asymmetric AArch32 systems (on top of the scheduler changes merged via the tip tree). - More entry.S clean-ups and conversion to C. - MTE updates: allow a preferred tag checking mode to be set per CPU (the overhead of synchronous mode is smaller for some CPUs than others); optimisations for kernel entry/exit path; optionally disable MTE on the kernel command line. - Kselftest improvements for SVE and signal handling, PtrAuth. - Fix unlikely race where a TLBI could use stale ASID on an ASID roll-over (found by inspection). - Miscellaneous fixes: disable trapping of PMSNEVFR_EL1 to higher exception levels; drop unnecessary sigdelsetmask() call in the signal32 handling; remove BUG_ON when failing to allocate SVE state (just signal the process); SYM_CODE annotations. - Other trivial clean-ups: use macros instead of magic numbers, remove redundant returns, typos. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAmEuYkoACgkQa9axLQDI XvEWVw/9HSWbccLrQ68ulaqZkL4r6lL2RqvZ2p6fkIRW7bX1JS4UJjWe3+VBg5Ed DQ1A5cHC5ZndQ4gCRsUhcq7IMXBSj3twMzK7yxBk3zh8tbhVrIOONsKMurMw1NyM OmoyTJ01i2ZrkDs0OU3fBlvIHPxBjKbOZqykOJHjrB2rwBSbsyUw2KvpM7ha8DOf O7gKViDrdAhumdIL9rsMvSiIPoJLCxvqeu55c3saVu1JrUR6ENu7lMu3jt4WrfK3 m5gf76IFbgxXvlLiC8RJW7OYaXZ+COb7RA/yP/lK+Y0ug9PwqTpzXDwqvAp8nBIv y7DK0umcBwfDWmwnRO+ZzNPjOGTHnOnjC07WNBPn3v03pMeJ8v8RnvzHkliek31P r6uFWBxWO/O0sBbSpR+4tzgNfir0RkMajwL5pxQCEMoPCucStYQQl8zIeJeJecpT DKIyKzfFw6O59gdhE6dCj2wXH8YmKUoSUPCAXpKGzK/oYVOGVQTZSZjIC++ydFWv AOXz77etPidk3/Tl15Ena7fkkMkxX9UM8dTjOFS64mSWlEyzE6FtfAgm2rIEOaG7 ps6IjVzVves39SC+yry8T2L6gsxPnanRfwKKCWHkovQzNFgs5Qt51Fd5eIeI1jZ0 uEZhd19FN4136QhjWJOeXL/eyj0bv1WLX/mUln95sHnKyf4je9w= =X6Wm -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Catalin Marinas: - Support for 32-bit tasks on asymmetric AArch32 systems (on top of the scheduler changes merged via the tip tree). - More entry.S clean-ups and conversion to C. - MTE updates: allow a preferred tag checking mode to be set per CPU (the overhead of synchronous mode is smaller for some CPUs than others); optimisations for kernel entry/exit path; optionally disable MTE on the kernel command line. - Kselftest improvements for SVE and signal handling, PtrAuth. - Fix unlikely race where a TLBI could use stale ASID on an ASID roll-over (found by inspection). - Miscellaneous fixes: disable trapping of PMSNEVFR_EL1 to higher exception levels; drop unnecessary sigdelsetmask() call in the signal32 handling; remove BUG_ON when failing to allocate SVE state (just signal the process); SYM_CODE annotations. - Other trivial clean-ups: use macros instead of magic numbers, remove redundant returns, typos. * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (56 commits) arm64: Do not trap PMSNEVFR_EL1 arm64: mm: fix comment typo of pud_offset_phys() arm64: signal32: Drop pointless call to sigdelsetmask() arm64/sve: Better handle failure to allocate SVE register storage arm64: Document the requirement for SCR_EL3.HCE arm64: head: avoid over-mapping in map_memory arm64/sve: Add a comment documenting the binutils needed for SVE asm arm64/sve: Add some comments for sve_save/load_state() kselftest/arm64: signal: Add a TODO list for signal handling tests kselftest/arm64: signal: Add test case for SVE register state in signals kselftest/arm64: signal: Verify that signals can't change the SVE vector length kselftest/arm64: signal: Check SVE signal frame shows expected vector length kselftest/arm64: signal: Support signal frames with SVE register data kselftest/arm64: signal: Add SVE to the set of features we can check for arm64: replace in_irq() with in_hardirq() kselftest/arm64: pac: Fix skipping of tests on systems without PAC Documentation: arm64: describe asymmetric 32-bit support arm64: Remove logic to kill 32-bit tasks on 64-bit-only cores arm64: Hook up cmdline parameter to allow mismatched 32-bit EL0 arm64: Advertise CPUs capable of running 32-bit applications in sysfs ... |

Merge branch 'exit-cleanups-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull exit cleanups from Eric Biederman: "In preparation of doing something about PTRACE_EVENT_EXIT I have started cleaning up various pieces of code related to do_exit. Most of that code I did not manage to get tested and reviewed before the merge window opened but a handful of very useful cleanups are ready to be merged. The first change is simply the removal of the bdflush system call. The code has now been disabled long enough that even the oldest userspace working userspace setups anyone can find to test are fine with the bdflush system call being removed. Changing m68k fsp040_die to use force_sigsegv(SIGSEGV) instead of calling do_exit directly is interesting only in that it is nearly the most difficult of the incorrect uses of do_exit to remove. The change to the seccomp code to simply send a signal instead of calling do_coredump directly is a very nice little cleanup made possible by realizing the existing signal sending helpers were missing a little bit of functionality that is easy to provide" * 'exit-cleanups-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: signal/seccomp: Dump core when there is only one live thread signal/seccomp: Refactor seccomp signal and coredump generation signal/m68k: Use force_sigsegv(SIGSEGV) in fpsp040_die exit/bdflush: Remove the deprecated bdflush system call |
