git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs Pull hw lockdown support from David Howells: "Annotation of module parameters that configure hardware resources including ioports, iomem addresses, irq lines and dma channels. This allows a future patch to prohibit the use of such module parameters to prevent that hardware from being abused to gain access to the running kernel image as part of locking the kernel down under UEFI secure boot conditions. Annotations are made by changing: module_param(n, t, p) module_param_named(n, v, t, p) module_param_array(n, t, m, p) to: module_param_hw(n, t, hwtype, p) module_param_hw_named(n, v, t, hwtype, p) module_param_hw_array(n, t, hwtype, m, p) where the module parameter refers to a hardware setting hwtype specifies the type of the resource being configured. This can be one of: ioport Module parameter configures an I/O port iomem Module parameter configures an I/O mem address ioport_or_iomem Module parameter could be either (runtime set) irq Module parameter configures an I/O port dma Module parameter configures a DMA channel dma_addr Module parameter configures a DMA buffer address other Module parameter configures some other value Note that the hwtype is compile checked, but not currently stored (the lockdown code probably won't require it). It is, however, there for future use. A bonus is that the hwtype can also be used for grepping. The intention is for the kernel to ignore or reject attempts to set annotated module parameters if lockdown is enabled. This applies to options passed on the boot command line, passed to insmod/modprobe or direct twiddling in /sys/module/ parameter files. The module initialisation then needs to handle the parameter not being set, by (1) giving an error, (2) probing for a value or (3) using a reasonable default. What I can't do is just reject a module out of hand because it may take a hardware setting in the module parameters. Some important modules, some ipmi stuff for instance, both probe for hardware and allow hardware to be manually specified; if the driver is aborts with any error, you don't get any ipmi hardware. Further, trying to do this entirely in the module initialisation code doesn't protect against sysfs twiddling. [!] Note that in and of itself, this series of patches should have no effect on the the size of the kernel or code execution - that is left to a patch in the next series to effect. It does mark annotated kernel parameters with a KERNEL_PARAM_FL_HWPARAM flag in an already existing field" * tag 'hwparam-20170420' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: (38 commits) Annotate hardware config module parameters in sound/pci/ Annotate hardware config module parameters in sound/oss/ Annotate hardware config module parameters in sound/isa/ Annotate hardware config module parameters in sound/drivers/ Annotate hardware config module parameters in fs/pstore/ Annotate hardware config module parameters in drivers/watchdog/ Annotate hardware config module parameters in drivers/video/ Annotate hardware config module parameters in drivers/tty/ Annotate hardware config module parameters in drivers/staging/vme/ Annotate hardware config module parameters in drivers/staging/speakup/ Annotate hardware config module parameters in drivers/staging/media/ Annotate hardware config module parameters in drivers/scsi/ Annotate hardware config module parameters in drivers/pcmcia/ Annotate hardware config module parameters in drivers/pci/hotplug/ Annotate hardware config module parameters in drivers/parport/ Annotate hardware config module parameters in drivers/net/wireless/ Annotate hardware config module parameters in drivers/net/wan/ Annotate hardware config module parameters in drivers/net/irda/ Annotate hardware config module parameters in drivers/net/hamradio/ Annotate hardware config module parameters in drivers/net/ethernet/ ...

2017-05-09qede: Split PF/VF ndos.Mintz, Yuval2-6/+21
PFs and VFs share the same structure of NDOs today, and the VFs explicitly fails the ndo_xdp() callback stating it doesn't support XDP.

As every dump request for the VF interface info would fail due to rtnl_xdp_fill() returning an error code.

2017-05-09net/mlx4_core: Reduce harmless SRIOV error message to debug levelJack Morgenstein2-4/+12
Under SRIOV resource management, extra counters are allocated to VFs from a free pool. If that pool is empty, the ALLOC_RES command for a counter resource fails -- and this generates a misleading error message in the message log. Under SRIOV, each VF is allocated (i.e., guaranteed) 2 counters -- one counter per port. For ETH ports, the RoCE driver requests an additional counter (above the guaranteed counters). If that request fails, the VF RoCE driver simply uses the default (i.e., guaranteed) counter for that port. Thus, failing to allocate an additional counter does not constitute a problem, and the error message on the PF when this occurs should be reduced to debug level. Finally, to identify the situation that the reason for the failure is that no resources are available to grant to the VF, we modified the error returned by mlx4_grant_resource to -EDQUOT (Quota exceeded), which more accurately describes the error.

While examining output from trial builds with -Wformat-security enabled, many strings were found that should be defined as "const", or as a char array instead of char pointer. This makes some static analysis easier, by producing fewer false positives. As these are all trivial changes, it seemed best to put them all in a single patch rather than chopping them up per maintainer.

2017-05-08treewide: use kv[mz]alloc* rather than opencoded variantsMichal Hocko14-106/+45
There are many code paths opencoding kvmalloc. Let's use the helper instead. The main difference to kvmalloc is that those users are usually not considering all the aspects of the memory allocator. E.g. allocation requests <= 32kB (with 4kB pages) are basically never failing and invoke OOM killer to satisfy the allocation. This sounds too disruptive for something that has a reasonable fallback - the vmalloc. On the other hand those requests might fallback to vmalloc even when the memory allocator would succeed after several more reclaim/compaction attempts previously. There is no guarantee something like that happens though. This patch converts many of those places to kv[mz]alloc* helpers because they are more conservative.

2017-05-08net: ethernet: ti: cpsw: adjust cpsw fifos depth for fullduplex flow controlGrygorii Strashko1-0/+16
When users set flow control using ethtool the bits are set properly in the CPGMAC_SL MACCONTROL register, but the FIFO depth in the respective Port n Maximum FIFO Blocks (Pn_MAX_BLKS) registers remains set to the minimum size reset value. When receive flow control is enabled on a port, the port's associated FIFO block allocation must be adjusted. The port RX allocation must increase to accommodate the flow control runout. The TRM recommends numbers of 5 or 6. Hence, apply required Port FIFO configuration to Pn_MAX_BLKS.Pn_TX_MAX_BLKS=0xF and Pn_MAX_BLKS.Pn_RX_MAX_BLKS=0x5 during interface initialization.

2017-05-03ibmvnic: Updated reset handlingNathan Fontenot2-157/+275
The ibmvnic driver has multiple handlers for resetting the driver depending on the reason the reset is needed (failover, lpm, fatal erors,...). All of the reset handlers do essentially the same thing, this patch moves this work to a common reset handler. By doing this we also allow the driver to better handle situations where we can get a reset while handling a reset. The updated reset handling works by adding a reset work item to the list of resets and then scheduling work to perform the reset. This step is necessary because we can receive a reset in interrupt context and we want to handle the reset out of interrupt context.

Small follow-up to d74a32acd59a ("xdp: use netlink extended ACK reporting") in order to let drivers all use the same NL_SET_ERR_MSG_MOD() helper macro for reporting. This also ensures that we consistently add the driver's prefix for dumping the report in user space to indicate that the error message is driver specific and not coming from core code. Furthermore, NL_SET_ERR_MSG_MOD() now reuses NL_SET_ERR_MSG() and thus makes all macros check the pointer as suggested.
