Updates to the GIC architecture allow ID_AA64PFR0_EL1.GIC to have values other than 0 or 1. At the moment, Linux is quite strict in the way it handles this field at early boot stage (cpufeature is fine) and will refuse to use the system register CPU interface if it doesn't find the value 1.

2019-02-19KVM: arm/arm64: Prefix header search paths with $(srctree)/Masahiro Yamada1-1/+1
Currently, the Kbuild core manipulates header search paths in a crazy way [1]. To fix this mess, I want all Makefiles to add explicit $(srctree)/ to the search paths in the srctree. Some Makefiles are already written in that way, but not all. The goal of this work is to make the notation consistent, and finally get rid of the gross hacks. Having whitespaces after -I does not matter since commit 48f6e3cf5bc6 ("kbuild: do not drop -I without parameter").

2019-02-19arm64: KVM: Describe data or unified caches as having 1 set and 1 wayArd Biesheuvel2-1/+17
On SMP ARM systems, cache maintenance by set/way should only ever be done in the context of onlining or offlining CPUs, which is typically done by bare metal firmware and never in a virtual machine. For this reason, we trap set/way cache maintenance operations and replace them with conditional flushing of the entire guest address space. Due to this trapping, the set/way arguments passed into the set/way ops are completely ignored, and thus irrelevant. This also means that the set/way geometry is equally irrelevant, and we can simply report it as 1 set and 1 way, so that legacy 32-bit ARM system software (i.e., the kind that only receives odd fixes) doesn't take a performance hit due to the trapping when iterating over the cachelines.

2019-02-19arm64: KVM: Expose sanitised cache type register to guestArd Biesheuvel3-2/+61
We currently permit CPUs in the same system to deviate in the exact topology of the caches, and we subsequently hide this fact from user space by exposing a sanitised value of the cache type register CTR_EL0. However, guests running under KVM see the bare value of CTR_EL0, which could potentially result in issues with, e.g., JITs or other pieces of code that are sensitive to misreported cache line sizes. So let's start trapping cache ID instructions if there is a mismatch, and expose the sanitised version of CTR_EL0 to guests. Note that CTR_EL0 is treated as an invariant to KVM user space, so update that part as well.

Actually they are quite similar, and we rely on kvm_arm_timer_[gs]et_reg() for the actual emulation anyways, so let's just merge all of those handlers into one function, which just marshalls the arguments and then hands off to a set of common accessors.

2019-02-19KVM: arm/arm64: Factor out VMID into struct kvm_vmidChristoffer Dall3-6/+16
In preparation for nested virtualization where we are going to have more than a single VMID per VM, let's factor out the VMID data into a separate VMID data structure and change the VMID allocator to operate on this new structure instead of using a struct kvm. This also means that udate_vttbr now becomes update_vmid, and that the vttbr itself is generated on the fly based on the stage 2 page table base address and the vmid. We cache the physical address of the pgd when allocating the pgd to avoid doing the calculation on every entry to the guest and to avoid calling into potentially non-hyp-mapped code from hyp/EL2. If we wanted to merge the VMID allocator with the arm64 ASID allocator at some point in the future, it should actually become easier to do that after this patch. Note that to avoid mapping the kvm_vmid_bits variable into hyp, we simply forego the masking of the vmid value in kvm_get_vttbr and rely on update_vmid to always assign a valid vmid value (within the supported range).

We currently eagerly save/restore MPIDR. It turns out to be slightly pointless: - On the host, this value is known as soon as we're scheduled on a physical CPU - In the guest, this value cannot change, as it is set by KVM (and this is a read-only register) The result of the above is that we can perfectly avoid the eager saving of MPIDR_EL1, and only keep the restore. We just have to setup the host contexts appropriately at boot time.

2019-02-19asm-generic: Make time32 syscall numbers optionalArnd Bergmann1-0/+1
We don't want new architectures to even provide the old 32-bit time_t based system calls any more, or define the syscall number macros. Add a new __ARCH_WANT_TIME32_SYSCALLS macro that gets enabled for all existing 32-bit architectures using the generic system call table, so we don't change any current behavior. Since this symbol is evaluated in user space as well, we cannot use a Kconfig CONFIG_* macro but have to define it in uapi/asm/unistd.h. On 64-bit architectures, the same system call numbers mostly refer to the system calls we want to keep, as they already pass 64-bit time_t. As new architectures no longer provide these, we need new exceptions in checksyscalls.sh. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

The newer prlimit64 syscall provides all the functionality of getrlimit and setrlimit syscalls and adds the pid of target process, so future architectures won't need to include getrlimit and setrlimit. Therefore drop getrlimit and setrlimit syscalls from the generic syscall list unless __ARCH_WANT_SET_GET_RLIMIT is defined by the architecture's unistd.h prior to including asm-generic/unistd.h, and adjust all architectures using the generic syscall list to define it so that no in-tree architectures are affected.

Ard suggested disabling this warning with Clang with a pragma so no neon code will have this type of error. While this is not at all an ideal solution, this build error is the only thing preventing KernelCI from having successful arm64 defconfig and allmodconfig builds on linux-next.

2019-02-18arm64: fix SSBS sanitizationMark Rutland1-7/+8
In valid_user_regs() we treat SSBS as a RES0 bit, and consequently it is unexpectedly cleared when we restore a sigframe or fiddle with GPRs via ptrace. This patch fixes valid_user_regs() to account for this, updating the function to refer to the latest ARM ARM (ARM DDI 0487D.a). For AArch32 tasks, SSBS appears in bit 23 of SPSR_EL1, matching its position in the AArch32-native PSR format, and we don't need to translate it as we have to for DIT. There are no other bit assignments that we need to account for today. As the recent documentation describes the DIT bit, we can drop our comment regarding DIT. While removing SSBS from the RES0 masks, existing inconsistent whitespace is corrected.

2019-02-16arm64, mm, efi: Account for GICv3 LPI tables in static memblock reserve tableArd Biesheuvel1-0/+11
In the irqchip and EFI code, we have what basically amounts to a quirk to work around a peculiarity in the GICv3 architecture, which permits the system memory address of LPI tables to be programmable only once after a CPU reset. This means kexec kernels must use the same memory as the first kernel, and thus ensure that this memory has not been given out for other purposes by the time the ITS init code runs, which is not very early for secondary CPUs. On systems with many CPUs, these reservations could overflow the memblock reservation table, and this was addressed in commit: eff896288872 ("efi/arm: Defer persistent reservations until after paging_init()") However, this turns out to have made things worse, since the allocation of page tables and heap space for the resized memblock reservation table itself may overwrite the regions we are attempting to reserve, which may cause all kinds of corruption, also considering that the ITS will still be poking bits into that memory in response to incoming MSIs. So instead, let's grow the static memblock reservation table on such systems so it can accommodate these reservations at an earlier time. This will permit us to revert the above commit in a subsequent patch.

The netfilter conflicts were rather simple overlapping changes. However, the cls_tcindex.c stuff was a bit more complex. On the 'net' side, Cong is fixing several races and memory leaks. Whilst on the 'net-next' side we have Vlad adding the rtnl-ness support. What I've decided to do, in order to resolve this, is revert the conversion over to using a workqueue that Cong did, bringing us back to pure RCU. I did it this way because I believe that either Cong's races don't apply with have Vlad did things, or Cong will have to implement the race fix slightly differently. Signed-off-by: David S.
