2018-05-25fpga: manager: change api, don't use drvdataAlan Tull13-71/+237
Change fpga_mgr_register to not set or use drvdata. This supports the case where a PCIe device has more than one manager. Add fpga_mgr_create/free functions. Change fpga_mgr_register and fpga_mgr_unregister functions to take the mgr struct as their only parameter. struct fpga_manager *fpga_mgr_create(struct device *dev, const char *name, const struct fpga_manager_ops *mops, void *priv); void fpga_mgr_free(struct fpga_manager *mgr); int fpga_mgr_register(struct fpga_manager *mgr); void fpga_mgr_unregister(struct fpga_manager *mgr); Update the drivers that call fpga_mgr_register with the new API.

2018-05-25fpga: region: don't use drvdata in common fpga codeAlan Tull2-1/+1
Changes to fpga_region_register function to not set drvdata. Setting drvdata is fine for DT based devices that will have one region per platform device. However PCIe based devices may have multiple FPGA regions under one PCIe device. Without these changes, the PCIe solution has to create an extra device for each child region to hold drvdata.

2018-05-14ver_linux: Drop redundant calls to system() to test if file is readableAlexander Kapshuk1-17/+11
Running 'test -r' on an awk variable name whose value is an empty string results in test being run with no arguments, and causes system() to return 0, which indicates success when used to test values returned by function calls. This results in code within the if blocks being run when it should not be. Instead of testing if a file is accessible and readable via calls to system("test -r " file), rely on the value returned by getline to perform this kind of testing. Getline returns -1 on error, with the code within the while loops not being run.

2018-05-14misc: IBM Virtual Management Channel Driver (VMC)Bryant G. Ly8-0/+2876
This driver is a logical device which provides an interface between the hypervisor and a management partition. This interface is like a message passing interface. This management partition is intended to provide an alternative to HMC-based system management. VMC enables the Management LPAR to provide basic logical partition functions: - Logical Partition Configuration - Boot, start, and stop actions for individual partitions - Display of partition status - Management of virtual Ethernet - Management of virtual Storage - Basic system management This driver is to be used for the POWER Virtual Management Channel Virtual Adapter on the PowerPC platform. It provides a character device which allows for both request/response and async message support through the /dev/ibmvmc node. Signed-off-by: Bryant G.

2018-05-14virt: vbox: Only copy_from_user the request-header onceWenwen Wang1-1/+3
In vbg_misc_device_ioctl(), the header of the ioctl argument is copied from the userspace pointer 'arg' and saved to the kernel object 'hdr'. Then the 'version', 'size_in', and 'size_out' fields of 'hdr' are verified. Before this commit, after the checks a buffer for the entire request would be allocated and then all data including the verified header would be copied from the userspace 'arg' pointer again. Given that the 'arg' pointer resides in userspace, a malicious userspace process can race to change the data pointed to by 'arg' between the two copies. By doing so, the user can bypass the verifications on the ioctl argument. This commit fixes this by using the already checked copy of the header to fill the header part of the allocated buffer and only copying the remainder of the data from userspace.

2018-05-14nubus: Call bus_register unconditionallyFinn Thain3-14/+9
Loading a NuBus driver module on a non-NuBus machine triggers the BUG_ON(!drv->bus->p) in driver_register(), because bus_register() was not called, because it is conditional on MACH_IS_MAC. Fix the crash by calling bus_register() unconditionally. Call it from a postcore_initcall(), like other busses do. Hence, the bus type is available for device_register(), which happens in a subsys initcall, and for driver_register(), which happens in a device or module initcall.

2018-05-14coresight: Remove %px for printing pcsr valueLeo Yan2-3/+3
The driver prints pcsr twice: the first time it uses specifier %px to print hexadecimal pcsr value and the second time uses specifier %pS for output kernel symbols. As suggested by Kees, using %pS should be sufficient and %px isn't necessary; the reason is if the pcsr is a kernel space address, we can easily get to know the code line from %pS format, on the other hand, if the pcsr value doesn't fall into kernel space range (e.g. if the CPU is stuck in firmware), %pS also gives out pcsr hexadecimal value. So this commit removes useless %px and update section "Output format" in the document for alignment between the code and document.

With VMBus protocol 5.0, we're able to better support new features, e.g. running two or more VMBus drivers simultaneously in a single VM -- note: we can't simply load the current VMBus driver twice, instead, a secondary VMBus driver must be implemented. This patch adds the support for the new VMBus protocol, which is available on new Windows hosts, by: 1) We still use SINT2 for compatibility; 2) We must use Connection ID 4 for the Initiate Contact Message, and for subsequent messages, we must use the Message Connection ID field in the host-returned VersionResponse Message. Notes for developers of the secondary VMBus driver: 1) Must use VMBus protocol 5.0 as well; 2) Must use a different SINT number that is not in use. 3) Must use Connection ID 4 for the Initiate Contact Message, and for subsequent messages, must use the Message Connection ID field in the host-returned VersionResponse Message. 4) It's possible that the primary VMBus driver using protocol version 4.0 can work with a secondary VMBus driver using protocol version 5.0, but it's recommended that both should use 5.0 for new Hyper-V features in the future.

However, when I profile binder working, it seems every binder buffers should be mapped in advance by binder_mmap. It means we could set VM_MIXEDMAP in binder_mmap time which is already hold a mmap_sem as down_write so binder_update_page_range doesn't need to hold a mmap_sem as down_write. Please use proper API down_read. It would help mmap_sem contention problem as well as fixing down_write abuse.

2018-05-14ANDROID: binder: remove 32-bit binder interface.Martijn Coenen2-18/+1
New devices launching with Android P need to use the 64-bit binder interface, even on 32-bit SoCs [0]. This change removes the Kconfig option to select the 32-bit binder interface. We don't think this will affect existing userspace for the following reasons: 1) The latest Android common tree is 4.14, so we don't believe any Android devices are on kernels >4.14. 2) Android devices launch on an LTS release and stick with it, so we wouldn't expect devices running on <= 4.14 now to upgrade to 4.17 or later. But even if they did, they'd rebuild the world (kernel + userspace) anyway. 3) Other userspaces like 'anbox' are already using the 64-bit interface. Note that this change doesn't remove the 32-bit UAPI itself; the reason for that is that Android userspace always uses the latest UAPI headers from upstream, and userspace retains 32-bit support for devices that are upgrading. This will be removed as well in 2-3 years, at which point we can remove the code from the UAPI as well. Finally, this change introduces build errors on archs where 64-bit get_user/put_user is not supported, so make binder unavailable on m68k (which wouldn't want it anyway).
