2018-01-19net: sched: cls: add extack support for tcf_exts_validateAlexander Aring
The tcf_exts_validate function calls the act api change callback. For preparing extack support for act api, this patch adds the extack as parameter for this function which is common used in cls implementations. Furthermore the tcf_exts_validate will call action init callback which prepares the TC action subsystem for extack support.

2018-01-19tcp: avoid min RTT bloat by skipping RTT from delayed-ACK in BBRYuchung Cheng
A persistent connection may send tiny amount of data (e.g. health-check) for a long period of time. BBR's windowed min RTT filter may only see RTT samples from delayed ACKs causing BBR to grossly over-estimate the path delay depending how much the ACK was delayed at the receiver. This patch skips RTT samples that are likely coming from delayed ACKs. Note that it is possible the sender never obtains a valid measure to set the min RTT. In this case BBR will continue to set cwnd to initial window which seems fine because the connection is thin stream.

2018-01-19RDMA/core: Simplify rdma_addr_get_sgid() to not support RoCEParav Pandit
Now that all callers who care about RoCE addresses have been converted to use rdma_read_gids() simplify rdma_addr_get_sgid() to only support real GID addresses. Callers should only use it for OPA and IB transports. The now deleted implementation for RoCE has several bugs related to IPv6 support and incorrect/inconsistent 'GID' addresses compared to the CM paths.

2018-01-19RDMA/cma: Introduce API to read GIDs for multiple transportsParav Pandit
This patch introduces an API that allows legacy applications to query GIDs for a rdma_cm_id which is used during connection establishment. GIDs are stored and created differently for iWarp, IB and RoCE transports. Therefore rdma_read_gids() returns GID for all the transports hiding such internal details to caller. It is usable for client side and server side connections. In general continued use of GID based addressing outside of IB is discouraged, so rdma_read_gids() should not be used by any new ULPs.

2018-01-19PCI: Add dummy pci_irqd_intx_xlate() for CONFIG_PCI=n buildNiklas Cassel
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 Heo
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.

This adds a new ioctl, KVM_PPC_GET_CPU_CHAR, that gives userspace information about the underlying machine's level of vulnerability to the recently announced vulnerabilities CVE-2017-5715, CVE-2017-5753 and CVE-2017-5754, and whether the machine provides instructions to assist software to work around the vulnerabilities. The ioctl returns two u64 words describing characteristics of the CPU and required software behaviour respectively, plus two mask words which indicate which bits have been filled in by the kernel, for extensibility. The bit definitions are the same as for the new H_GET_CPU_CHARACTERISTICS hypercall. There is also a new capability, KVM_CAP_PPC_GET_CPU_CHAR, which indicates whether the new ioctl is available.
