2018-03-24vgacon: Set VGA struct resource typesBjorn Helgaas
[ Upstream commit c82084117f79bcae085e40da526253736a247120 ] Set the resource type when we reserve VGA-related I/O port resources. The resource code doesn't actually look at the type, so it inserts resources without a type in the tree correctly even without this change. But if we ever print a resource without a type, it looks like this: vga+ [??? 0x000003c0-0x000003df flags 0x0] Setting the type means it will be printed correctly as: vga+ [io 0x000003c0-0x000003df] Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Signed-off-by: Sasha Levin <alexander.levin@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

[ Upstream commit a25fb8508c1b80dce742dbeaa4d75a1e9f2c5617 ] Starting from gcc-5.4+ gcc generates MLX instructions in more cases to refer local symbols: https://gcc.gnu.org/PR60465 That caused ia64 module loader to choke on such instructions: fuse: invalid slot number 1 for IMM64 The Linux kernel used to handle only case where relocation pointed to slot=2 instruction in the bundle. That limitation was fixed in linux by commit 9c184a073bfd ("[IA64] Fix 2.6 kernel for the new ia64 assembler") See http://sources.redhat.com/bugzilla/show_bug.cgi?id=1433 This change lifts the slot=2 restriction from the kernel module loader. Tested on 'fuse' and 'btrfs' kernel modules.

[ Upstream commit 2c949ce38f4e81d7487f165fa3b8f77d74a2a6c4 ] The PCIe programming sequence in TRM suggests CLKSTCTRL of PCIe should be set to SW_WKUP. There are no issues when CLKSTCTRL is set to HW_AUTO in RC mode. However in EP mode, the host system is not able to access the MEMSPACE and setting the CLKSTCTRL to SW_WKUP fixes it.

2018-03-24ARM: 8668/1: ftrace: Fix dynamic ftrace with DEBUG_RODATA and !FRAME_POINTERAbel Vesa
[ Upstream commit 6f05d0761af612e04572ba4d65b4c0274a88444f ] The support for dynamic ftrace with CONFIG_DEBUG_RODATA involves overriding the weak arch_ftrace_update_code() with a variant which makes the kernel text writable around the patching. This override was however added under the CONFIG_OLD_MCOUNT ifdef, and CONFIG_OLD_MCOUNT is only enabled if frame pointers are enabled. This leads to non-functional dynamic ftrace (ftrace triggers a WARN_ON()) when CONFIG_DEBUG_RODATA is enabled and CONFIG_FRAME_POINTER is not. Move the override out of that ifdef and into the CONFIG_DYNAMIC_FTRACE ifdef where it belongs.

2018-03-24KVM: PPC: Book3S PR: Exit KVM on failed mappingAlexey Kardashevskiy
[ Upstream commit bd9166ffe624000140fc6b606b256df01fc0d060 ] At the moment kvmppc_mmu_map_page() returns -1 if mmu_hash_ops.hpte_insert() fails for any reason so the page fault handler resumes the guest and it faults on the same address again. This adds distinction to kvmppc_mmu_map_page() to return -EIO if mmu_hash_ops.hpte_insert() failed for a reason other than full pteg. At the moment only pSeries_lpar_hpte_insert() returns -2 if plpar_pte_enter() failed with a code other than H_PTEG_FULL. Other mmu_hash_ops.hpte_insert() instances can only fail with -1 "full pteg". With this change, if PR KVM fails to update HPT, it can signal the userspace about this instead of returning to guest and having the very same page fault over and over again.

2018-03-24x86: i8259: export legacy_pic symbolHans de Goede
[ Upstream commit 7ee06cb2f840a96be46233181ed4557901a74385 ] The classic PC rtc-coms driver has a workaround for broken ACPI device nodes for it which lack an irq resource. This workaround used to unconditionally hardcode the irq to 8 in these cases. This was causing irq conflict problems on systems without a legacy-pic so a recent patch added an if (nr_legacy_irqs()) guard to the workaround to avoid this irq conflict. nr_legacy_irqs() uses the legacy_pic symbol under the hood causing an undefined symbol error if the rtc-cmos code is build as a module. This commit exports the legacy_pic symbol to fix this.

2018-03-24BACKPORT, FROMLIST: crypto: arm64/speck - add NEON-accelerated ↵Eric Biggers
implementation of Speck-XTS Add a NEON-accelerated implementation of Speck128-XTS and Speck64-XTS for ARM64. This is ported from the 32-bit version. It may be useful on devices with 64-bit ARM CPUs that don't have the Cryptography Extensions, so cannot do AES efficiently -- e.g. the Cortex-A53 processor on the Raspberry Pi 3. It generally works the same way as the 32-bit version, but there are some slight differences due to the different instructions, registers, and syntax available in ARM64 vs. in ARM32. For example, in the 64-bit version there are enough registers to hold the XTS tweaks for each 128-byte chunk, so they don't need to be saved on the stack. Benchmarks on a Raspberry Pi 3 running a 64-bit kernel: Algorithm Encryption Decryption --------- ---------- ---------- Speck64/128-XTS (NEON) 92.2 MB/s 92.2 MB/s Speck128/256-XTS (NEON) 75.0 MB/s 75.0 MB/s Speck128/256-XTS (generic) 47.4 MB/s 35.6 MB/s AES-128-XTS (NEON bit-sliced) 33.4 MB/s 29.6 MB/s AES-256-XTS (NEON bit-sliced) 24.6 MB/s 21.7 MB/s The code performs well on higher-end ARM64 processors as well, though such processors tend to have the Crypto Extensions which make AES preferred. For example, here are the same benchmarks run on a HiKey960 (with CPU affinity set for the A73 cores), with the Crypto Extensions implementation of AES-256-XTS added: Algorithm Encryption Decryption --------- ----------- ----------- AES-256-XTS (Crypto Extensions) 1273.3 MB/s 1274.7 MB/s Speck64/128-XTS (NEON) 359.8 MB/s 348.0 MB/s Speck128/256-XTS (NEON) 292.5 MB/s 286.1 MB/s Speck128/256-XTS (generic) 186.3 MB/s 181.8 MB/s AES-128-XTS (NEON bit-sliced) 142.0 MB/s 124.3 MB/s AES-256-XTS (NEON bit-sliced) 104.7 MB/s 91.1 MB/s Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> (cherry picked from commit 91a2abb78f940ac821345cb7cc376dca94336c2f git://git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev-2.6.git master) (changed speck-neon-glue.c to use blkcipher API instead of skcipher API) (resolved merge conflicts in arch/arm64/crypto/Makefile and arch/arm64/crypto/Kconfig) (made CONFIG_CRYPTO_SPECK_NEON select CONFIG_CRYPTO_GF128MUL, since gf128mul_x_ble() is non-inline in older kernels) Change-Id: Iaed7a14c84b32b09ec299060a5d27060693043d5 Signed-off-by: Eric Biggers <ebiggers@google.com>

[ Upstream commit 5bba7aa4958e271c3ffceb70d47d3206524cf489 ] Fix the problem of inaccurate identification of instructions BLEZL and BGTZL in R2 emulation code by making sure all necessary encoding specifications are met. Previously, certain R6 instructions could be identified as BLEZL or BGTZL. R2 emulation routine didn't take into account that both BLEZL and BGTZL instructions require their rt field (bits 20 to 16 of instruction encoding) to be 0, and that, at same time, if the value in that field is not 0, the encoding may represent a legitimate MIPS R6 instruction. This means that a problem could occur after emulation optimization, when emulation routine tried to pipeline emulation, picked up a next candidate, and subsequently misrecognized an R6 instruction as BLEZL or BGTZL. It should be said that for single pass strategy, the problem does not happen because CPU doesn't trap on branch-compacts which share opcode space with BLEZL/BGTZL (but have rt field != 0, of course).

2018-03-18x86: Treat R_X86_64_PLT32 as R_X86_64_PC32H.J. Lu
commit b21ebf2fb4cde1618915a97cc773e287ff49173e upstream. On i386, there are 2 types of PLTs, PIC and non-PIC. PIE and shared objects must use PIC PLT. To use PIC PLT, you need to load _GLOBAL_OFFSET_TABLE_ into EBX first. There is no need for that on x86-64 since x86-64 uses PC-relative PLT. On x86-64, for 32-bit PC-relative branches, we can generate PLT32 relocation, instead of PC32 relocation, which can also be used as a marker for 32-bit PC-relative branches. Linker can always reduce PLT32 relocation to PC32 if function is defined locally. Local functions should use PC32 relocation. As far as Linux kernel is concerned, R_X86_64_PLT32 can be treated the same as R_X86_64_PC32 since Linux kernel doesn't use PLT. R_X86_64_PLT32 for 32-bit PC-relative branches has been enabled in binutils master branch which will become binutils 2.31. [ hjl is working on having better documentation on this all, but a few more notes from him: "PLT32 relocation is used as marker for PC-relative branches. Because of EBX, it looks odd to generate PLT32 relocation on i386 when EBX doesn't have GOT. As for symbol resolution, PLT32 and PC32 relocations are almost interchangeable. But when linker sees PLT32 relocation against a protected symbol, it can resolved locally at link-time since it is used on a branch instruction. Linker can't do that for PC32 relocation" but for the kernel use, the two are basically the same, and this commit gets things building and working with the current binutils master - Linus ] Signed-off-by: H.J.

This is a silent failure which can corrupt memory in unexpected places. On x86, the bytes of data being overwritten by relocations are always initialized to zero beforehand.

2018-03-18x86/MCE: Serialize sysfs changesSeunghun Han
commit b3b7c4795ccab5be71f080774c45bbbcc75c2aaf upstream. The check_interval file in /sys/devices/system/machinecheck/machinecheck<cpu number> directory is a global timer value for MCE polling. If it is changed by one CPU, mce_restart() broadcasts the event to other CPUs to delete and restart the MCE polling timer and __mcheck_cpu_init_timer() reinitializes the mce_timer variable. If more than one CPU writes a specific value to the check_interval file concurrently, mce_timer is not protected from such concurrent accesses and all kinds of explosions happen. Since only root can write to those sysfs variables, the issue is not a big deal security-wise. However, concurrent writes to these configuration variables is void of reason so the proper thing to do is to serialize the access with a mutex.

2018-03-18MIPS: BMIPS: Do not mask IPIs during suspendJustin Chen
commit 06a3f0c9f2725f5d7c63c4203839373c9bd00c28 upstream. Commit a3e6c1eff548 ("MIPS: IRQ: Fix disable_irq on CPU IRQs") fixes an issue where disable_irq did not actually disable the irq. The bug caused our IPIs to not be disabled, which actually is the correct behavior. With the addition of commit a3e6c1eff548 ("MIPS: IRQ: Fix disable_irq on CPU IRQs"), the IPIs were getting disabled going into suspend, thus schedule_ipi() was not being called. This caused deadlocks where schedulable task were not being scheduled and other cpus were waiting for them to do something. Add the IRQF_NO_SUSPEND flag so an irq_disable will not be called on the IPIs during suspend.

2018-03-11bpf, x64: implement retpoline for tail callDaniel Borkmann
[ upstream commit a493a87f38cfa48caaa95c9347be2d914c6fdf29 ] Implement a retpoline [0] for the BPF tail call JIT'ing that converts the indirect jump via jmp %rax that is used to make the long jump into another JITed BPF image. Since this is subject to speculative execution, we need to control the transient instruction sequence here as well when CONFIG_RETPOLINE is set, and direct it into a pause + lfence loop. The latter aligns also with what gcc / clang emits (e.g. [1]). JIT dump after patch: # bpftool p d x i 1 0: (18) r2 = map[id:1] 2: (b7) r3 = 0 3: (85) call bpf_tail_call#12 4: (b7) r0 = 2 5: (95) exit With CONFIG_RETPOLINE: # bpftool p d j i 1 [...] 33: cmp %edx,0x24(%rsi) 36: jbe 0x0000000000000072 |* 38: mov 0x24(%rbp),%eax 3e: cmp $0x20,%eax 41: ja 0x0000000000000072 | 43: add $0x1,%eax 46: mov %eax,0x24(%rbp) 4c: mov 0x90(%rsi,%rdx,8),%rax 54: test %rax,%rax 57: je 0x0000000000000072 | 59: mov 0x28(%rax),%rax 5d: add $0x25,%rax 61: callq 0x000000000000006d |+ 66: pause | 68: lfence | 6b: jmp 0x0000000000000066 | 6d: mov %rax,(%rsp) | 71: retq | 72: mov $0x2,%eax [...] * relative fall-through jumps in error case + retpoline for indirect jump Without CONFIG_RETPOLINE: # bpftool p d j i 1 [...] 33: cmp %edx,0x24(%rsi) 36: jbe 0x0000000000000063 |* 38: mov 0x24(%rbp),%eax 3e: cmp $0x20,%eax 41: ja 0x0000000000000063 | 43: add $0x1,%eax 46: mov %eax,0x24(%rbp) 4c: mov 0x90(%rsi,%rdx,8),%rax 54: test %rax,%rax 57: je 0x0000000000000063 | 59: mov 0x28(%rax),%rax 5d: add $0x25,%rax 61: jmpq *%rax |- 63: mov $0x2,%eax [...] * relative fall-through jumps in error case - plain indirect jump as before [0] https://support.google.com/faqs/answer/7625886 [1] https://github.com/gcc-mirror/gcc/commit/a31e654fa107be968b802786d747e962c2fcdb2b Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2018-03-11x86/syscall: Sanitize syscall table de-references under speculation fixJiri Slaby
In 4.4.118, we have commit c8961332d6da (x86/syscall: Sanitize syscall table de-references under speculation), which is a backport of upstream commit 2fbd7af5af86. But it fixed only the C part of the upstream patch -- the IA32 sysentry. So it ommitted completely the assembly part -- the 64bit sysentry. Fix that in this patch by explicit array_index_mask_nospec written in assembly. The same was used in lib/getuser.S. However, to have "sbb" working properly, we have to switch from "cmp" against (NR_syscalls-1) to (NR_syscalls), otherwise the last syscall number would be "and"ed by 0. It is because the original "ja" relies on "CF" or "ZF", but we rely only on "CF" in "sbb". That means: switch to "jae" conditional jump too. Final note: use rcx for mask as this is exactly what is overwritten by the 4th syscall argument (r10) right after.

2018-03-03MIPS: Implement __multi3 for GCC7 MIPS64r6 buildsJames Hogan
commit ebabcf17bcd7ce968b1631ebe08236275698f39b upstream. GCC7 is a bit too eager to generate suboptimal __multi3 calls (128bit multiply with 128bit result) for MIPS64r6 builds, even in code which doesn't explicitly use 128bit types, such as the following: unsigned long func(unsigned long a, unsigned long b) { return a > (~0UL) / b; } Which GCC rearanges to: return (unsigned __int128)a * (unsigned __int128)b > 0xffffffffffffffff; Therefore implement __multi3, but only for MIPS64r6 with GCC7 as under normal circumstances we wouldn't expect any calls to __multi3 to be generated from kernel code.
