arm64: Fix memblock current_limit with 64K pages and 48-bit VA
With 48-bit VA space, the 64K page configuration uses 3 levels instead of 2 and PUD_SIZE != PMD_SIZE. Since with 64K pages we only cover PMD_SIZE with the initial swapper_pg_dir populated in head.S, the memblock current_limit needs to be set accordingly in map_mem() to avoid allocating unmapped memory. The memblock current_limit is progressively increased as more blocks are mapped. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> |

arm64: ASLR: Don't randomise text when randomise_va_space == 0
When user asks to turn off ASLR by writing "0" to /proc/sys/kernel/randomize_va_space there should not be any randomization to mmap base, stack, VDSO, libs, text and heap Currently arm64 violates this behavior by randomising text. Fix this by defining a constant ELF_ET_DYN_BASE. The randomisation of mm->mmap_base is done by setup_new_exec -> arch_pick_mmap_layout -> mmap_base -> mmap_rnd.

The compat_elf_prpsinfo structure does not match the arch/arm struct elf_pspsinfo definition. As result NT_PRPSINFO note in core file created by arm64 kernel for aarch32 (compat) process has wrong size. So gdb cannot display command that caused process crash.

arm64: Align less than PAGE_SIZE pgds naturally
When the pgd size is smaller than PAGE_SIZE, pgd_alloc() uses kzalloc() to save space. However, this is not always naturally aligned as required by the architecture. This patch creates a kmem_cache for pgd allocations with the correct alignment. The current kernel configurations with 4K pages + 39-bit VA and 64K pages + 42-bit VA use a full page for the pgd and are not affected. The patch is required for 48-bit VA with 64K pages where the pgd is 512 bytes.

Merge git://git.infradead.org/users/eparis/audit
Pull audit updates from Eric Paris: "So this change across a whole bunch of arches really solves one basic problem. We want to audit when seccomp is killing a process. seccomp hooks in before the audit syscall entry code. audit_syscall_entry took as an argument the arch of the given syscall. Since the arch is part of what makes a syscall number meaningful it's an important part of the record, but it isn't available when seccomp shoots the syscall... For most arch's we have a better way to get the arch (syscall_get_arch) So the solution was two fold: Implement syscall_get_arch() everywhere there is audit which didn't have it. Use syscall_get_arch() in the seccomp audit code. Having syscall_get_arch() everywhere meant it was a useless flag on the stack and we could get rid of it for the typical syscall entry. The other changes inside the audit system aren't grand, fixed some records that had invalid spaces. Better locking around the task comm field. Removing some dead functions and structs. Make some things static.

arm/arm64: KVM: Fix BE accesses to GICv2 EISR and ELRSR regs
The EIRSR and ELRSR registers are 32-bit registers on GICv2, and we store these as an array of two such registers on the vgic vcpu struct. However, we access them as a single 64-bit value or as a bitmap pointer in the generic vgic code, which breaks BE support. Instead, store them as u64 values on the vgic structure and do the word-swapping in the assembly code, which already handles the byte order for BE systems.

arm64: KVM: Implement 48 VA support for KVM EL2 and Stage-2
This patch adds the necessary support for all host kernel PGSIZE and VA_SPACE configuration options for both EL2 and the Stage-2 page tables. However, for 40bit and 42bit PARange systems, the architecture mandates that VTCR_EL2.SL0 is maximum 1, resulting in fewer levels of stage-2 pagge tables than levels of host kernel page tables. At the same time, systems with a PARange > 42bit, we limit the IPA range by always setting VTCR_EL2.T0SZ to 24. To solve the situation with different levels of page tables for Stage-2 translation than the host kernel page tables, we allocate a dummy PGD with pointers to our actual inital level Stage-2 page table, in order for us to reuse the kernel pgtable manipulation primitives. Reproducing all these in KVM does not look pretty and unnecessarily complicates the 32-bit side. Systems with a PARange < 40bits are not yet supported. [ I have reworked this patch from its original form submitted by Jungseok to take the architecture constraints into consideration. There were too many changes from the original patch for me to preserve the authorship. Thanks to Catalin Marinas for his help in figuring out a good solution to this challenge. I have also fixed various bugs and missing error code handling from the original patch. - Christoffer ] Reviewed-by: Catalin Marinas <catalin.marinas@arm.com> Acked-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Jungseok Lee <jungseoklee85@gmail.com> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org> |

"This set fixes a bunch of fallout from the changes that went in during
this merge window, particularly:
- Fix fsl_pq_mdio (Claudiu Manoil) and fm10k (Pranith Kumar) build
failures.
- Several networking drivers do atomic_set() on page counts where
that's not exactly legal. From Eric Dumazet.
- Make __skb_flow_get_ports() work cleanly with unaligned data, from
Alexander Duyck.
- Fix some kernel-doc buglets in rfkill and netlabel, from Fabian
Frederick.
- Unbalanced enable_irq_wake usage in bcmgenet and systemport
drivers, from Florian Fainelli.
- pxa168_eth needs to depend on HAS_DMA, from Geert Uytterhoeven.
- Multi-dequeue in the qdisc layer severely bypasses the fairness
limits the previous code used to enforce, reintroduce in a way that
at the same time doesn't compromise bulk dequeue opportunities.
From Jesper Dangaard Brouer.
- macvlan receive path unnecessarily hops through a softirq by using
netif_rx() instead of netif_receive_skb(). From Jason Baron"

arm64: kvm: define PAGE_S2_DEVICE as read-only by default
Now that we support read-only memslots, we need to make sure that pass-through device mappings are not mapped writable if the guest has requested them to be read-only. The existing implementation already honours this by calling kvm_set_s2pte_writable() on the new pte in case of writable mappings, so all we need to do is define the default pgprot_t value used for devices to be PTE_S2_RDONLY.

arm/arm64: KVM: add 'writable' parameter to kvm_phys_addr_ioremap
Add support for read-only MMIO passthrough mappings by adding a 'writable' parameter to kvm_phys_addr_ioremap. For the moment, mappings will be read-write even if 'writable' is false, but once the definition of PAGE_S2_DEVICE gets changed, those mappings will be created read-only.

arm64: mm: enable RCU fast_gup
Activate the RCU fast_gup for ARM64. We also need to force THP splits to broadcast an IPI s.t. we block in the fast_gup page walker.

In order to implement fast_get_user_pages we need to ensure that the page table walker is protected from page table pages being freed from under it.

ARM64: SoC changes for 3.18
Starting with 3.18, we are merging SoC-specific changes for arm64 through the arm-soc tree, like we have been doing for arm32. This time, there is only one set of changes, adding support for the Cavium "Thunder" Soc family. Since the changes are relatively small, this includes Kconfig, defconfig and DT changes. If all goes well, we will never require adding actual C source code for platform support in arm64, given that the architecture is more clearly defined and we have moved out a lot of the platform specifics into device drivers for arm32 already. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAVDWU/WCrR//JCVInAQKOOw//coW/sJM6kR3LMXNfcpLazHxBeUFRtI7n rq1aKOEl6X7p1SVckT42amq4gcYnw7zbv71hSa1P9hEINIhFGMwISNexPEHhugll zqqF8ArurjGXaWKtAJNc3RHlYsGkOlwdrx2qWNEvTmU0YtgfCHwEnaNCypqpsDI+ VrIpJ6M/DGgTHW7FfsJZ4GJviidLm2afCV7EBBIxSeCLdgj32dYbwDCCMERL9qUT 7//d+UZiLKemdL1YdGSE/Ql7ppGxJtyFKfwq1FWmDSR1aRJrXW3VpkW8qoUhmwyN 6rNSL31T/lv/uXy6tOKtVfp/rzuDGvhaU9RF8B63jv9/pXiEBCWLB7Y+/LXve7Ds ZsA/ghG3QgyJp+OANu/N9uFPr2X7eJ7XxuBek7ex1hgcGr97cxCoI4qv0OCqR//+ NnoOYDS6WABudghN7csXzfRoJAIz1HqSAqQUVTzSpdi+U+eeibrTXCZp72RS8CY7 SntTlDP8+GGxoe71rm7GCJxVFXu6RUzaDwfFJLCZQqegeZhpleMPlXD7gM+BNDod hTP3HGxo8iLjjF1v86JU+u7qwaiuB3azrxD+whKJPdm7UgIrdnYvIgMc1ZMYaBGQ 6se7wQ8lZpYXQPuZAGjl5JOpZBIGtlE8KdYFT833MKbRJlqPM8OVJ7F5l9ayYkC2 csU7fIgJduI= =sqqq -----END PGP SIGNATURE----- Merge tag 'arm64-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM64 SoC changes from Arnd Bergmann: "Starting with 3.18, we are merging SoC-specific changes for arm64 through the arm-soc tree, like we have been doing for arm32.

- Use static inline instead of extern inline in ftrace code.
- Crypto ARM assembly updates for big endian
- Alignment of initrd/.init memory to page sizes when freeing to
ensure that we fully free the regions
- Add gcov support
- A couple of preparatory patches for VDSO support: use
_install_special_mapping, and randomize the sigpage placement above
stack.
- Add L2 ePAPR DT cache properties so that DT can specify the cache
geometry.
- Preparatory patch for FIQ (NMI) kernel C code for things like
spinlock lockup debug. Following on from this are a couple of my
patches cleaning up show_regs() and removing an unused (probably
since 1.x days) do_unexp_fiq() function.

Fixes and features for 3.18.
Apart from the usual cleanups, here is the summary of new features:
- s390 moves closer towards host large page support
- PowerPC has improved support for debugging (both inside the guest and
via gdbstub) and support for e6500 processors
- ARM/ARM64 support read-only memory (which is necessary to put firmware
in emulated NOR flash)
- x86 has the usual emulator fixes and nested virtualization improvements
(including improved Windows support on Intel and Jailhouse hypervisor
support on AMD), adaptive PLE which helps overcommitting of huge guests.
Also included are some patches that make KVM more friendly to memory
hot-unplug, and fixes for rare caching bugs.
Two patches have trivial mm/ parts that were acked by Rik and Andrew.
Note: I will soon switch to a subkey for signing purposes. To verify
future signed pull requests from me, please update my key with
"gpg --recv-keys 9B4D86F2". You should see 3 new subkeys---the
one for signing will be a 2048-bit RSA key, 4E6B09D7.

arm64/efi: Do not enter virtual mode if booting with efi=noruntime or noefi
In case efi runtime disabled via noefi kernel cmdline arm64_enter_virtual_mode should error out. At the same time move early_memunmap(memmap.map, mapsize) to the beginning of the function or it will leak early mem.

ARM64: make of_device_ids const
of_device_ids (i.e. compatible strings and the respective data) are not supposed to change at runtime. All functions working with of_device_ids provided by <linux/of.h> work with const of_device_ids. So mark the only non-const struct in arch/arm64 as const, too. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> |

arm{,64}/xen: Remove "EXPERIMENTAL" in the description of the Xen options
The Xen ARM API is stable since Xen 4.4 and everything has been upstreamed in Linux for ARM and ARM64. Therefore we can drop "EXPERIMENTAL" from the Xen option in the both Kconfig.
