2020-07-31bpf, arm64: Add BPF exception tablesJean-Philippe Brucker3-9/+108
When a tracing BPF program attempts to read memory without using the bpf_probe_read() helper, the verifier marks the load instruction with the BPF_PROBE_MEM flag. Since the arm64 JIT does not currently recognize this flag it falls back to the interpreter. Add support for BPF_PROBE_MEM, by appending an exception table to the BPF program. If the load instruction causes a data abort, the fixup infrastructure finds the exception table and fixes up the fault, by clearing the destination register and jumping over the faulting instruction. To keep the compact exception table entry format, inspect the pc in fixup_exception(). A more generic solution would add a "handler" field to the table entry, like on x86 and s390.

Although iph is expected to point to at least 20 bytes of valid memory, ihl may be bogus, for example on reception of a corrupt packet. If it happens to be less than 5, we really don't want to run away and dereference 16GB worth of memory until it wraps back to exactly zero...

2020-07-30arm64/alternatives: move length validation inside the subsectionSami Tolvanen1-2/+2
Commit f7b93d42945c ("arm64/alternatives: use subsections for replacement sequences") breaks LLVM's integrated assembler, because due to its one-pass design, it cannot compute instruction sequence lengths before the layout for the subsection has been finalized. This change fixes the build by moving the .org directives inside the subsection, so they are processed after the subsection layout is known.

2020-07-30KVM: arm64: Handle data and instruction external aborts the same wayWill Deacon1-6/+3
If the guest generates a synchronous external abort which is not handled by the host, we inject it back into the guest as a virtual SError, but only if the original fault was reported on the data side. Instruction faults are reported as "Unsupported FSC", causing the vCPU run loop to bail with -EFAULT. Although synchronous external aborts from a guest are pretty unusual, treat them the same regardless of whether they are taken as data or instruction aborts by EL2.

2020-07-30KVM: arm64: Ensure that all nVHE hyp code is in .hyp.textDavid Brazdil1-3/+23
Some compilers may put a subset of generated functions into '.text.*' ELF sections and the linker may leverage this division to optimize ELF layout. Unfortunately, the recently introduced HYPCOPY command assumes that all executable code (with the exception of specialized sections such as '.hyp.idmap.text') is in the '.text' section. If this assumption is broken, code in '.text.*' will be merged into kernel proper '.text' instead of the '.hyp.text' that is mapped in EL2. To ensure that this cannot happen, insert an OBJDUMP assertion into HYPCOPY. The command dumps a list of ELF sections in the input object file and greps for '.text.'. If found, compilation fails. Tested with both binutils' and LLVM's objdump (the output format is different). GCC offers '-fno-reorder-functions' to disable this behaviour. Select the flag if it is available. From inspection of GCC source (latest Git in July 2020), this flag does force all code into '.text'. By default, GCC uses profile data, heuristics and attributes to select a subsection. LLVM/Clang currently does not have a similar optimization pass. It can place static constructors into '.text.startup' and it's optimizer can be provided with profile data to reorder hot/cold functions. Neither of these is applicable to nVHE hyp code. If this changes in the future, the OBJDUMP assertion should alert users to the problem.

2020-07-30arm64/mm: save memory access in check_and_switch_context() fast switch pathPingfan Liu2-8/+8
On arm64, smp_processor_id() reads a per-cpu `cpu_number` variable, using the per-cpu offset stored in the tpidr_el1 system register. In some cases we generate a per-cpu address with a sequence like: cpu_ptr = &per_cpu(ptr, smp_processor_id()); Which potentially incurs a cache miss for both `cpu_number` and the in-memory `__per_cpu_offset` array. This can be written more optimally as: cpu_ptr = this_cpu_ptr(ptr); Which only needs the offset from tpidr_el1, and does not need to load from memory. The following two test cases show a small performance improvement measured on a 46-cpus qualcomm machine with 5.8.0-rc4 kernel. Test 1: (about 0.3% improvement) #cat b.sh make clean && make all -j138 #perf stat --repeat 10 --null --sync sh b.sh - before this patch Performance counter stats for 'sh b.sh' (10 runs): 298.62 +- 1.86 seconds time elapsed ( +- 0.62% ) - after this patch Performance counter stats for 'sh b.sh' (10 runs): 297.734 +- 0.954 seconds time elapsed ( +- 0.32% ) Test 2: (about 1.69% improvement) 'perf stat -r 10 perf bench sched messaging' Then sum the total time of 'sched/messaging' by manual. - before this patch total 0.707 sec for 10 times - after this patch totol 0.695 sec for 10 times Signed-off-by: Pingfan Liu <kernelfans@gmail.com> Acked-by: Mark Rutland <mark.rutland@arm.com> Cc: Will Deacon <will@kernel.org> Cc: Steve Capper <steve.capper@arm.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Vladimir Murzin <vladimir.murzin@arm.com> Cc: Jean-Philippe Brucker <jean-philippe@linaro.org> Link: https://lore.kernel.org/r/1594389852-19949-1-git-send-email-kernelfans@gmail.com Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

If a stage-2 page-table contains an executable, read-only mapping at the pte level (e.g. due to dirty logging being enabled), a subsequent write fault to the same page which tries to install a larger block mapping (e.g. due to dirty logging having been disabled) will erroneously inherit the exec permission and consequently skip I-cache invalidation for the rest of the block. Ensure that exec permission is only inherited by write faults when the new mapping is of the same size as the existing one.

So far, vcpu_has_ptrauth() is implemented in terms of system_supports_*_auth() calls, which are declared "inline". In some specific conditions (clang and SCS), the "inline" very much turns into an "out of line", which leads to a fireworks when this predicate is evaluated on a non-VHE system (right at the beginning of __hyp_handle_ptrauth). Instead, make sure vcpu_has_ptrauth gets expanded inline by directly using the cpus_have_final_cap() helpers, which are __always_inline, generate much better code, and are the only thing that make sense when running at EL2 on a nVHE system.

2020-07-27arm64: dts: qcom: bullhead: Move UART pinctrl to SoCKonrad Dybcio1-9/+4
This pinout is common for every 8992-based device and should therefore reside in the SoC device tree. Also convert addresses into phandles.

2020-07-27arm64: dts: qcom: bullhead: Add qcom,msm-idKonrad Dybcio1-0/+1
Add the property required for the bootloader to select the correct device tree blob. It has been removed from the SoC device tree as it should be set on a per-device basis.

2020-07-27arm64: dts: qcom: msm8992: Fix SDHCI1Konrad Dybcio2-7/+15
This commit ensures the correct IRQ type is set and disables the device by default. The mmc-hs400-1_8v property is also moved to Bullhead as it might not be present on all boards. The node has been renamed to sdhci@ instead of mmc@ and the phandle was changed to sdhc_1 to comply with the newer DTS style.

2020-07-27arm64: dts: qcom: msm8992: Modernize the DTS styleKonrad Dybcio2-168/+168
Following changes have been made: - remove name, compatible and msm-id - wrap clocks in clocks{} - order nodes by name and by address - clock_gcc -> gcc - msmgpio -> tlmm - retire msm8992-pins.dtsi - add some of the missing pins - make comments C-style - make apcs a mailbox Signed-off-by: Konrad Dybcio <konradybcio@gmail.com> Link: https://lore.kernel.org/r/20200625182118.131476-2-konradybcio@gmail.com Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2020-07-27arm64: dts: qcom: Add support for Sony Xperia Z5 (SoMC Sumire-RoW)Konrad Dybcio3-0/+249
Add device tree support for the Sony Xperia Z5 smartphone. It's based on Sony Kitakami platform (msm8994) and hence a Kitakami-common DTSI has been created so as to reduce clutter when remaining devices are added. The board currently supports * Serial * SDHCI * I2C * Regulator configuration * pstore log dump * GPIO keys Signed-off-by: Konrad Dybcio <konradybcio@gmail.com> Link: https://lore.kernel.org/r/20200624150107.76234-9-konradybcio@gmail.com [bjorn: Changed vendor identifier in board compatible from somc to sony] Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2020-07-27arm64: dts: qcom: Move msm8994-smd-rpm contents to lg-bullhead.Konrad Dybcio3-315/+224
This was the only device using that dtsi, so no point keeping it separate AND with a confusing name (bullhead is based on msm8992 and the file contains regulator values for that specific board).
