2018-01-22pinctrl: Forward declare struct deviceLadislav Michl1-0/+2
pinctrl/devinfo.h is using forward declaration from pinctrl/consumer.h for configurations with CONFIG_PINCTRL defined, however nothing declares it in the opposite case. Fix this by adding a forward declaration. Signed-off-by: Ladislav Michl <[email protected]> Signed-off-by: Linus Walleij <[email protected]>

2018-01-21mm, page_vma_mapped: Drop faulty pointer arithmetics in check_pte()Kirill A. Shutemov1-0/+21
Tetsuo reported random crashes under memory pressure on 32-bit x86 system and tracked down to change that introduced page_vma_mapped_walk(). The root cause of the issue is the faulty pointer math in check_pte(). As ->pte may point to an arbitrary page we have to check that they are belong to the section before doing math. Otherwise it may lead to weird results. It wasn't noticed until now as mem_map[] is virtually contiguous on flatmem or vmemmap sparsemem. Pointer arithmetic just works against all 'struct page' pointers. But with classic sparsemem, it doesn't because each section memap is allocated separately and so consecutive pfns crossing two sections might have struct pages at completely unrelated addresses. Let's restructure code a bit and replace pointer arithmetic with operations on pfns. Signed-off-by: Kirill A.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2018-01-19 From: Or Gerlitz <[email protected]> ======= First six patches of this series further enhances the mlx5 hairpin support. The first two patches deal with using different hairpin instances for flows whose packets have different priorities to align with the port TX QoS model. The next four patches allow us to do HW spreading of flows over a set of hairpin pairs using RSS. The last two patches change the driver to also set the size of the HW hairpin queues. ======== Next four patches from Eran Ben Elisha <[email protected]>: Add more debug data for TX timeout handling, and further enhance and optimize TX timeout handling upon lost interrupts, which adds a mechanism for explicitly polling EQ in case of a TX timeout in order to recover from a lost interrupt. If this is not the case (no pending EQEs), perform a channels full recovery as usual. From Kamal Heib <[email protected]>, Two patches to extend the stats group API to have an update_stats() callback which will be used to fetch the hardware or software counters data, this will improve the current API and reduce code duplication.

In support of removing the VM_MIXEDMAP indication from DAX VMAs, introduce pfn_t_special() for drivers to indicate that _PAGE_SPECIAL should be used for DAX ptes. This also helps identify drivers like dccssblk that only want to use DAX in a read-only fashion without get_user_pages() support. Ideally we could delete axonram and dcssblk DAX support, but if we need to keep it better make it explicit that axonram and dcssblk only support a sub-set of DAX due to missing _PAGE_DEVMAP support.

2018-01-19PCI: Add dummy pci_irqd_intx_xlate() for CONFIG_PCI=n buildNiklas Cassel1-0/+7
Some hardware can operate in either "host" or "endpoint" mode, which means there can be both a host bridge driver and an endpoint driver for the same device. Those drivers share a lot of code, so sometimes they live in the same source file. The host bridge driver requires CONFIG_PCI=y because it enumerates PCI devices below the bridge using the PCI core. The endpoint driver does not require CONFIG_PCI=y because it runs in an embedded kernel on the other side of the device, e.g., on an adapter card. pci-dra7xx.c contains both host and endpoint drivers. If we select only the endpoint driver (CONFIG_PCI=n and CONFIG_PCI_DRA7XX_EP=y), the unneeded host driver is still compiled. It references pci_irqd_intx_xlate(), which is not present when CONFIG_PCI=n, which causes this error: drivers/pci/dwc/pci-dra7xx.c:229:11: error: 'pci_irqd_intx_xlate' undeclared here (not in a function) Add a dummy pci_irqd_intx_xlate() for the CONFIG_PCI=n case.

2018-01-19string: drop __must_check from strscpy() and restore strscpy() usages in cgroupTejun Heo1-1/+1
e7fd37ba1217 ("cgroup: avoid copying strings longer than the buffers") converted possibly unsafe strncpy() usages in cgroup to strscpy(). However, although the callsites are completely fine with truncated copied, because strscpy() is marked __must_check, it led to the following warnings. kernel/cgroup/cgroup.c: In function ‘cgroup_file_name’: kernel/cgroup/cgroup.c:1400:10: warning: ignoring return value of ‘strscpy’, declared with attribute warn_unused_result [-Wunused-result] strscpy(buf, cft->name, CGROUP_FILE_NAME_MAX); ^ To avoid the warnings, 50034ed49645 ("cgroup: use strlcpy() instead of strscpy() to avoid spurious warning") switched them to strlcpy(). strlcpy() is worse than strlcpy() because it unconditionally runs strlen() on the source string, and the only reason we switched to strlcpy() here was because it was lacking __must_check, which doesn't reflect any material differences between the two function. It's just that someone added __must_check to strscpy() and not to strlcpy(). These basic string copy operations are used in variety of ways, and one of not-so-uncommon use cases is safely handling truncated copies, where the caller naturally doesn't care about the return value. The __must_check doesn't match the actual use cases and forces users to opt for inferior variants which lack __must_check by happenstance or spread ugly (void) casts. Remove __must_check from strscpy() and restore strscpy() usages in cgroup.

2018-01-18bpf: add new jited info fields in bpf_dev_offload and bpf_prog_infoJiong Wang1-0/+2
For host JIT, there are "jited_len"/"bpf_func" fields in struct bpf_prog used by all host JIT targets to get jited image and it's length. While for offload, targets are likely to have different offload mechanisms that these info are kept in device private data fields. Therefore, BPF_OBJ_GET_INFO_BY_FD syscall needs an unified way to get JIT length and contents info for offload targets. One way is to introduce new callback to parse device private data then fill those fields in bpf_prog_info. This might be a little heavy, the other way is to add generic fields which will be initialized by all offload targets. This patch follow the second approach to introduce two new fields in struct bpf_dev_offload and teach bpf_prog_get_info_by_fd about them to fill correct jited_prog_len and jited_prog_insns in bpf_prog_info.

That's not just for gold, it's a general robustness improvement. - An improved error message for objtool which spares tearing hairs. - Make KASAN fail loudly if there is not enough memory instead of oopsing at some random place later - RSB fill on context switch to prevent RSB underflow and speculation through other units. - Make the retpoline/RSB functionality work reliably for both Intel and AMD - Add retpoline to the module version magic so mismatch can be detected - A small (non-fix) update for cpufeatures which prevents cpu feature clashing for the upcoming extra mitigation bits to ease backporting" * 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: module: Add retpoline tag to VERMAGIC x86/cpufeature: Move processor tracing out of scattered features objtool: Improve error message for bad file argument objtool: Fix seg fault with gold linker x86/retpoline: Add LFENCE to the retpoline/RSB filling RSB macros x86/retpoline: Fill RSB on context switch for affected CPUs x86/kasan: Panic if there is not enough memory to boot
2018-01-17nvme-pci: clean up SMBSZ bit definitionsChristoph Hellwig1-8/+14
Define the bit positions instead of macros using the magic values, and move the expanded helpers to calculate the size and size unit into the implementation C file.

2018-01-17net/mlx5: Fix build breakSaeed Mahameed1-2/+0
The latest merge between net and net-next introduced a complier assert in mlx5 driver. In hca_cap_bits older fields are kept along with newer fields that should have replaced them.

2018-01-17iommu: Clean up of_iommu_init_fnRobin Murphy1-4/+1
Now that no more drivers rely on arbitrary early initialisation via an of_iommu_init_fn hook, let's clean up the redundant remnants. The IOMMU_OF_DECLARE() macro needs to remain for now, as the probe-deferral mechanism has no other nice way to detect built-in drivers before they have registered themselves, such that it can make the right decision.

2018-01-17dm: move dm_table_destroy() to same header as dm_table_create()Brian Norris1-0/+5
If anyone is going to use dm_table_create(), they probably should be able to use dm_table_destroy() too. Move the dm_table_destroy() definition outside the private header, near dm_table_create() Signed-off-by: Brian Norris <[email protected]> Signed-off-by: Mike Snitzer <[email protected]>
