* cxgb4: Simplify PCIe Completion Timeout settingBjorn Helgaas2017-12-181-18/+3
| | | | | | | | | Simplify PCIe Completion Timeout setting by using the pcie_capability_clear_and_set_word() interface. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* sfp: fix EEPROM reading in the case of non-SFF8472 SFPsRussell King2017-12-181-4/+3
| | | | | | | | | | | The EEPROM reading was trying to read from the second EEPROM address if we requested the last byte from the SFF8079 EEPROM, which caused a failure when the second EEPROM is not present.

* net: phy: meson-gxl: leave CONFIG_A6 untouchedJerome Brunet2017-12-181-9/+0
| | | | | | | | | | | | | | | | | The PHY performs just as well when left in its default configuration and it makes senses because this poke gets reset just after init. According to the documentation, all registers in the Analog/DSP bank are reset when there is a mode switch from 10BT to 100BT. The bank is also reset on power down and soft reset, so we will never see the value which may have been set by the bootloader. In the end, we have used the default configuration so far and there is no reason to change now. Remove CONFIG_A6 poke to make this clear.

* sfc: populate the timer reload fieldBert Kenward2017-12-181-2/+3
| | | | | | | | | | | | The timer mode register now has a separate field for the reload value. Since we always use this timer with the reload (for interrupt moderation) we set this to the same as the initial value.

The main changes are: 1) Allow arbitrary function calls from one BPF function to another BPF function. As of today when writing BPF programs, __always_inline had to be used in the BPF C programs for all functions, unnecessarily causing LLVM to inflate code size. Handle this more naturally with support for BPF to BPF calls such that this __always_inline restriction can be overcome. As a result, it allows for better optimized code and finally enables to introduce core BPF libraries in the future that can be reused out of different projects. x86 and arm64 JIT support was added as well, from Alexei. 2) Add infrastructure for tagging functions as error injectable and allow for BPF to return arbitrary error values when BPF is attached via kprobes on those. This way of injecting errors generically eases testing and debugging without having to recompile or restart the kernel. Tags for opting-in for this facility are added with BPF_ALLOW_ERROR_INJECTION(), from Josef. 3) For BPF offload via nfp JIT, add support for bpf_xdp_adjust_head() helper call for XDP programs. First part of this work adds handling of BPF capabilities included in the firmware, and the later patches add support to the nfp verifier part and JIT as well as some small optimizations, from Jakub. 4) The bpftool now also gets support for basic cgroup BPF operations such as attaching, detaching and listing current BPF programs. As a requirement for the attach part, bpftool can now also load object files through 'bpftool prog load'. This reuses libbpf which we have in the kernel tree as well. bpftool-cgroup man page is added along with it, from Roman. 5) Back then commit e87c6bc3852b ("bpf: permit multiple bpf attachments for a single perf event") added support for attaching multiple BPF programs to a single perf event. Given they are configured through perf's ioctl() interface, the interface has been extended with a PERF_EVENT_IOC_QUERY_BPF command in this work in order to return an array of one or multiple BPF prog ids that are currently attached, from Yonghong. 6) Various minor fixes and cleanups to the bpftool's Makefile as well as a new 'uninstall' and 'doc-uninstall' target for removing bpftool itself or prior installed documentation related to it, from Quentin. 7) Add CONFIG_CGROUP_BPF=y to the BPF kernel selftest config file which is required for the test_dev_cgroup test case to run, from Naresh. 8) Fix reporting of XDP prog_flags for nfp driver, from Jakub. 9) Fix libbpf's exit code from the Makefile when libelf was not found in the system, also from Jakub. ==================== Signed-off-by: David S.

Otherwise, existing but not yet polled CQEs can be returned out of order to the user application. This can happen when the QP has exited RTS but not yet flushed the QP, which can happen during a normal close (vs abortive close). In addition never count the drain CQEs when determining how many CQEs need to be synthesized during the flush operation. This latter issue should never happen if the QP is properly flushed before inserting the drain CQE, but I wanted to avoid corrupting the CQ state. So we handle it and log a warning once.

| | * | IB/core: Don't enforce PKey security on SMI MADsDaniel Jurgens2017-12-071-2/+5

Checking the pkey on SMI MADs is not necessary, and it seems that some older adapters using the mthca driver don't follow the convention of using the default PKey, resulting in false denials, or errors querying the PKey cache. SMI MAD security is still enforced, only agents allowed to manage the subnet are able to receive or send SMI MADs.
