2022-02-04lib/crypto: blake2s: avoid indirect calls to compression function for Clang CFIJason A. Donenfeld
blake2s_compress_generic is weakly aliased by blake2s_compress. The current harness for function selection uses a function pointer, which is ordinarily inlined and resolved at compile time. But when Clang's CFI is enabled, CFI still triggers when making an indirect call via a weak symbol. This seems like a bug in Clang's CFI, as though it's bucketing weak symbols and strong symbols differently. It also only seems to trigger when "full LTO" mode is used, rather than "thin LTO". [ 0.000000][ T0] Kernel panic - not syncing: CFI failure (target: blake2s_compress_generic+0x0/0x1444) [ 0.000000][ T0] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 5.16.0-mainline-06981-g076c855b846e #1 [ 0.000000][ T0] Hardware name: MT6873 (DT) [ 0.000000][ T0] Call trace: [ 0.000000][ T0] dump_backtrace+0xfc/0x1dc [ 0.000000][ T0] dump_stack_lvl+0xa8/0x11c [ 0.000000][ T0] panic+0x194/0x464 [ 0.000000][ T0] __cfi_check_fail+0x54/0x58 [ 0.000000][ T0] __cfi_slowpath_diag+0x354/0x4b0 [ 0.000000][ T0] blake2s_update+0x14c/0x178 [ 0.000000][ T0] _extract_entropy+0xf4/0x29c [ 0.000000][ T0] crng_initialize_primary+0x24/0x94 [ 0.000000][ T0] rand_initialize+0x2c/0x6c [ 0.000000][ T0] start_kernel+0x2f8/0x65c [ 0.000000][ T0] __primary_switched+0xc4/0x7be4 [ 0.000000][ T0] Rebooting in 5 seconds.. Nonetheless, the function pointer method isn't so terrific anyway, so this patch replaces it with a simple boolean, which also gets inlined away. This successfully works around the Clang bug. In general, I'm not too keen on all of the indirection involved here; it clearly does more harm than good. Hopefully the whole thing can get cleaned up down the road when lib/crypto is overhauled more comprehensively. But for now, we go with a simple bandaid.

2022-01-27ftrace: Have architectures opt-in for mcount build time sortingSteven Rostedt (Google)
First S390 complained that the sorting of the mcount sections at build time caused the kernel to crash on their architecture. Now PowerPC is complaining about it too. And also ARM64 appears to be having issues. It may be necessary to also update the relocation table for the values in the mcount table. Not only do we have to sort the table, but also update the relocations that may be applied to the items in the table. If the system is not relocatable, then it is fine to sort, but if it is, some architectures may have issues (although x86 does not as it shifts all addresses the same). Add a HAVE_BUILDTIME_MCOUNT_SORT that an architecture can set to say it is safe to do the sorting at build time. Also update the config to compile in build time sorting in the sorttable code in scripts/ to depend on CONFIG_BUILDTIME_MCOUNT_SORT.

2022-01-22mm: remove cleancacheChristoph Hellwig
Patch series "remove Xen tmem leftovers". Since the removal of the Xen tmem driver in 2019, the cleancache hooks are entirely unused, as are large parts of frontswap. This series against linux-next (with the folio changes included) removes cleancaches, and cuts down frontswap to the bits actually used by zswap. This patch (of 13): The cleancache subsystem is unused since the removal of Xen tmem driver in commit 814bbf49dcd0 ("xen: remove tmem driver").

2022-01-19ARM: 9180/1: Thumb2: align ALT_UP() sections in modules sufficientlyArd Biesheuvel
When building for Thumb2, the .alt.smp.init sections that are emitted by the ALT_UP() patching code may not be 32-bit aligned, even though the fixup_smp_on_up() routine expects that. This results in alignment faults at module load time, which need to be fixed up by the fault handler. So let's align those sections explicitly, and prevent this from occurring.

2022-01-19ARM: 9179/1: uaccess: avoid alignment faults in copy_[from|to]_kernel_nofaultArd Biesheuvel
The helpers that are used to implement copy_from_kernel_nofault() and copy_to_kernel_nofault() cast a void* to a pointer to a wider type, which may result in alignment faults on ARM if the compiler decides to use double-word or multiple-word load/store instructions. Only configurations that define CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS=y are affected, given that commit 2423de2e6f4d ("ARM: 9115/1: mm/maccess: fix unaligned copy_{from,to}_kernel_nofault") ensures that dst and src are sufficiently aligned otherwise. So use the unaligned accessors for accessing dst and src in cases where they may be misaligned.

2022-01-19ARM: 9170/1: fix panic when kasan and kprobe are enabledsparkhuang
arm32 uses software to simulate the instruction replaced by kprobe. some instructions may be simulated by constructing assembly functions. therefore, before executing instruction simulation, it is necessary to construct assembly function execution environment in C language through binding registers. after kasan is enabled, the register binding relationship will be destroyed, resulting in instruction simulation errors and causing kernel panic. the kprobe emulate instruction function is distributed in three files: actions-common.c actions-arm.c actions-thumb.c, so disable KASAN when compiling these files. for example, use kprobe insert on cap_capable+20 after kasan enabled, the cap_capable assembly code is as follows: <cap_capable>: e92d47f0 push {r4, r5, r6, r7, r8, r9, sl, lr} e1a05000 mov r5, r0 e280006c add r0, r0, #108 ; 0x6c e1a04001 mov r4, r1 e1a06002 mov r6, r2 e59fa090 ldr sl, [pc, #144] ; ebfc7bf8 bl c03aa4b4 <__asan_load4> e595706c ldr r7, [r5, #108] ; 0x6c e2859014 add r9, r5, #20 ......

The end-game which I have not yet reached yet is for fatal signals that generate coredumps to be short-circuit deliverable from complete_signal, for force_siginfo_to_task not to require changing userspace configured signal delivery state, and for the ptrace stops to always happen in locations where we can guarantee on all architectures that the all of the registers are saved and available on the stack. Removal of profile_task_ext, profile_munmap, and profile_handoff_task are the big successes for dead code removal this round. A bunch of small bug fixes are included, as most of the issues reported were small enough that they would not affect bisection so I simply added the fixes and did not fold the fixes into the changes they were fixing. There was a bug that broke coredumps piped to systemd-coredump. I dropped the change that caused that bug and replaced it entirely with something much more restrained. Unfortunately that required some rebasing. Some successes after this set of changes: There are few enough calls to do_exit to audit in a reasonable amount of time. The lifetime of struct kthread now matches the lifetime of struct task, and the pointer to struct kthread is no longer stored in set_child_tid. The flag SIGNAL_GROUP_COREDUMP is removed. The field group_exit_task is removed. Issues where task->exit_code was examined with signal->group_exit_code should been examined were fixed.

2022-01-14kbuild: rename cmd_{bzip2,lzma,lzo,lz4,xzkern,zstd22}Masahiro Yamada
GZIP-compressed files end with 4 byte data that represents the size of the original input. The decompressors (the self-extracting kernel) exploit it to know the vmlinux size beforehand. To mimic the GZIP's trailer, Kbuild provides cmd_{bzip2,lzma,lzo,lz4,xzkern,zstd22}. Unfortunately these macros are used everywhere despite the appended size data is only useful for the decompressors. There is no guarantee that such hand-crafted trailers are safely ignored. In fact, the kernel refuses compressed initramdfs with the garbage data. That is why usr/Makefile overrides size_append to make it no-op. To limit the use of such broken compressed files, this commit renames the existing macros as follows: cmd_bzip2 --> cmd_bzip2_with_size cmd_lzma --> cmd_lzma_with_size cmd_lzo --> cmd_lzo_with_size cmd_lz4 --> cmd_lz4_with_size cmd_xzkern --> cmd_xzkern_with_size cmd_zstd22 --> cmd_zstd22_with_size To keep the decompressors working, I updated the following Makefiles accordingly: arch/arm/boot/compressed/Makefile arch/h8300/boot/compressed/Makefile arch/mips/boot/compressed/Makefile arch/parisc/boot/compressed/Makefile arch/s390/boot/compressed/Makefile arch/sh/boot/compressed/Makefile arch/x86/boot/compressed/Makefile I reused the current macro names for the normal usecases; they produce the compressed data in the proper format. I did not touch the following: arch/arc/boot/Makefile arch/arm64/boot/Makefile arch/csky/boot/Makefile arch/mips/boot/Makefile arch/riscv/boot/Makefile arch/sh/boot/Makefile kernel/Makefile This means those Makefiles will stop appending the size data. I dropped the 'override size_append' hack from usr/Makefile. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nicolas Schier <n.schier@avm.de>

git://git.kernel.org/pub/scm/linux/kernel/git/crng/random Pull random number generator updates from Jason Donenfeld: "These a bit more numerous than usual for the RNG, due to folks resubmitting patches that had been pending prior and generally renewed interest. There are a few categories of patches in here: 1) Dominik Brodowski and I traded a series back and forth for a some weeks that fixed numerous issues related to seeds being provided at extremely early boot by the firmware, before other parts of the kernel or of the RNG have been initialized, both fixing some crashes and addressing correctness around early boot randomness. One of these is marked for stable. 2) I replaced the RNG's usage of SHA-1 with BLAKE2s in the entropy extractor, and made the construction a bit safer and more standard. This was sort of a long overdue low hanging fruit, as we were supposed to have phased out SHA-1 usage quite some time ago (even if all we needed here was non-invertibility). Along the way it also made extraction 131% faster. This required a bit of Kconfig and symbol plumbing to make things work well with the crypto libraries, which is one of the reasons why I'm sending you this pull early in the cycle. 3) I got rid of a truly superfluous call to RDRAND in the hot path, which resulted in a whopping 370% increase in performance. 4) Sebastian Andrzej Siewior sent some patches regarding PREEMPT_RT, the full series of which wasn't ready yet, but the first two preparatory cleanups were good on their own. One of them touches files in kernel/irq/, which is the other reason why I'm sending you this pull early in the cycle. 5) Other assorted correctness fixes from Eric Biggers, Jann Horn, Mark Brown, Dominik Brodowski, and myself" * 'random-5.17-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: random: don't reset crng_init_cnt on urandom_read() random: avoid superfluous call to RDRAND in CRNG extraction random: early initialization of ChaCha constants random: use IS_ENABLED(CONFIG_NUMA) instead of ifdefs random: harmonize "crng init done" messages random: mix bootloader randomness into pool random: do not throw away excess input to crng_fast_load random: do not re-init if crng_reseed completes before primary init random: fix crash on multiple early calls to add_bootloader_randomness() random: do not sign extend bytes for rotation when mixing random: use BLAKE2s instead of SHA1 in extraction lib/crypto: blake2s: include as built-in random: fix data race on crng init time random: fix data race on crng_node_pool irq: remove unused flags argument from __handle_irq_event_percpu() random: remove unused irq_flags argument from add_interrupt_randomness() random: document add_hwgenerator_randomness() with other input functions MAINTAINERS: add git tree for random.c

2022-01-07lib/crypto: blake2s: include as built-inJason A. Donenfeld
In preparation for using blake2s in the RNG, we change the way that it is wired-in to the build system. Instead of using ifdefs to select the right symbol, we use weak symbols. And because ARM doesn't need the generic implementation, we make the generic one default only if an arch library doesn't need it already, and then have arch libraries that do need it opt-in. So that the arch libraries can remain tristate rather than bool, we then split the shash part from the glue code.

2022-01-06arm/xen: Read extended regions from DT and init Xen resourceOleksandr Tyshchenko
This patch implements arch_xen_unpopulated_init() on Arm where the extended regions (if any) are gathered from DT and inserted into specific Xen resource to be used as unused address space for Xen scratch pages by unpopulated-alloc code. The extended region (safe range) is a region of guest physical address space which is unused and could be safely used to create grant/foreign mappings instead of wasting real RAM pages from the domain memory for establishing these mappings. The extended regions are chosen by the hypervisor at the domain creation time and advertised to it via "reg" property under hypervisor node in the guest device-tree. As region 0 is reserved for grant table space (always present), the indexes for extended regions are 1...N. If arch_xen_unpopulated_init() fails for some reason the default behaviour will be restored (allocate xenballooned pages). This patch also removes XEN_UNPOPULATED_ALLOC dependency on x86.

2022-01-06arm/xen: Switch to use gnttab_setup_auto_xlat_frames() for DTOleksandr Tyshchenko
Read the start address of the grant table space from DT (region 0). This patch mostly restores behaviour before commit 3cf4095d7446 ("arm/xen: Use xen_xlate_map_ballooned_pages to setup grant table") but trying not to break the ACPI support added after that commit. So the patch touches DT part only and leaves the ACPI part with xen_xlate_map_ballooned_pages(). Also in order to make a code more resilient use a fallback to xen_xlate_map_ballooned_pages() if grant table region wasn't found. This is a preparation for using Xen extended region feature where unused regions of guest physical address space (provided by the hypervisor) will be used to create grant/foreign/whatever mappings instead of wasting real RAM pages from the domain memory for establishing these mappings. The immediate benefit of this change: - Avoid superpage shattering in Xen P2M when establishing stage-2 mapping (GFN <-> MFN) for the grant table space - Avoid wasting real RAM pages (reducing the amount of memory usuable) for mapping grant table space - The grant table space is always mapped at the exact same place (region 0 is reserved for the grant table) Signed-off-by: Oleksandr Tyshchenko <oleksandr_tyshchenko@epam.com> Reviewed-by: Stefano Stabellini <sstabellini@kernel.org> Link: https://lore.kernel.org/r/1639080336-26573-3-git-send-email-olekstysh@gmail.com Signed-off-by: Juergen Gross <jgross@suse.com>

2021-12-27ARM: dts: socfpga: change qspi to "intel,socfpga-qspi"Dinh Nguyen
Because of commit 9cb2ff111712 ("spi: cadence-quadspi: Disable Auto-HW polling"), which does a write to the CQSPI_REG_WR_COMPLETION_CTRL register regardless of any condition. Well, the Cadence QuadSPI controller on Intel's SoCFPGA platforms does not implement the CQSPI_REG_WR_COMPLETION_CTRL register, thus a write to this register results in a crash! So starting with v5.16, I introduced the patch 98d948eb833 ("spi: cadence-quadspi: fix write completion support"), which adds the dts compatible "intel,socfpga-qspi" that is specific for versions that doesn't have the CQSPI_REG_WR_COMPLETION_CTRL register implemented.
