2022-02-10x86/sgx: Silence softlockup detection when releasing large enclavesReinette Chatre1-0/+2
Vijay reported that the "unclobbered_vdso_oversubscribed" selftest triggers the softlockup detector. Actual SGX systems have 128GB of enclave memory or more. The "unclobbered_vdso_oversubscribed" selftest creates one enclave which consumes all of the enclave memory on the system. Tearing down such a large enclave takes around a minute, most of it in the loop where the EREMOVE instruction is applied to each individual 4k enclave page. Spending one minute in a loop triggers the softlockup detector. Add a cond_resched() to give other tasks a chance to run and placate the softlockup detector.

2022-02-10riscv: fix build with binutils 2.38Aurelien Jarno1-0/+6
From version 2.38, binutils default to ISA spec version 20191213. This means that the csr read/write (csrr*/csrw*) instructions and fence.i instruction has separated from the `I` extension, become two standalone extensions: Zicsr and Zifencei. As the kernel uses those instruction, this causes the following build failure: CC arch/riscv/kernel/vdso/vgettimeofday.o <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h: Assembler messages: <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01' <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01' <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01' <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01' The fix is to specify those extensions explicitely in -march. However as older binutils version do not support this, we first need to detect that.

Xen allows the usage of some previously reserved bits in the IO-APIC RTE and the MSI address fields in order to store high bits for the target APIC ID. Such feature is already implemented by QEMU/KVM and HyperV, so in order to enable it just add the handler that checks for it's presence.

Mayuresh reported commit 20802d8d477d ("riscv: extable: add a dedicated uaccess handler") breaks the writev02 test case in LTP. This is due to the err reg isn't correctly set with the errno(-EFAULT in writev02 case). First of all, the err and zero regs are reg numbers rather than reg offsets in struct pt_regs; Secondly, regs_set_gpr() should write the regs when offset isn't zero(zero means epc) Fix it by correcting regs_set_gpr() logic and passing the correct reg offset to it.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes Fixes for omaps A series of fixes for omap variants for minor issues, and a fix for a timer regression for some omap3 beagleboard versions. The timer fix needs to patch both the dts and the timer code because otherwise the timer quirk handling for old dtbs will prevent the dts fix from working. The other changes are for issues found by automated analysis, a macasp typo fix, and two cosmetic fixes for clocks. * tag 'omap-for-v5.17/fixes-for-merge-window-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: Don't use legacy clock defines for dra7 clkctrl clk: ti: Move dra7 clock devices out of the legacy section ARM: dts: Fix timer regression for beagleboard revision c ARM: dts: am335x-wega: Fix typo in mcasp property rx-num-evt ARM: OMAP2+: adjust the location of put_device() call in omapdss_init_of ARM: OMAP2+: hwmod: Add of_node_put() before break Link: https://lore.kernel.org/r/pull-1641801310-149268@atomide.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2022-02-04lib/crypto: blake2s: avoid indirect calls to compression function for Clang CFIJason A. Donenfeld2-4/+4
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".

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.

2022-02-04riscv: eliminate unreliable __builtin_frame_address(1)Changbin Du1-4/+5
I tried different pieces of code which uses __builtin_frame_address(1) (with both gcc version 7.5.0 and 10.3.0) to verify whether it works as expected on riscv64. The result is negative. What the compiler had generated is as below: 31 fp = (unsigned long)__builtin_frame_address(1); 0xffffffff80006024 <+200>: ld s1,0(s0) It takes '0(s0)' as the address of frame 1 (caller), but the actual address should be '-16(s0)'. | ... | <-+ +-----------------+ | | return address | | | previous fp | | | saved registers | | | local variables | | $fp --> | ... | | +-----------------+ | | return address | | | previous fp --------+ | saved registers | $sp --> | local variables | +-----------------+ This leads the kernel can not dump the full stack trace on riscv.
