* MFC 294366:John Baldwin2016-01-231-1/+1
| | | | | | | | | | | | | | | | | Initialize vm_page_prot to VM_MEMATTR_DEFAULT instead of 0. If a driver's Linux mmap callback passed vm_page_prot through unchanged, then linux_dev_mmap_single() would try to apply whatever VM_MEMATTR_xxx value 0 is to the mapping. On x86, VM_MEMATTR_DEFAULT is the PAT value for write-back (WB) which is 6, while 0 maps to the PAT value for uncacheable (UC). Thus, any mmap request that did not explicitly set page_prot was tried to map memory as UC triggering the warning in sg_pager_getpages().

| | | | | | | | | | | | | | | | | | Currently the Linux character device mmap handling only supports mmap operations that map a single page that has an associated vm_page_t. This does not permit mapping larger regions (such as a PCI memory BAR) and it does not permit mapping addresses beyond the top of RAM (such as a 64-bit BAR located above the top of RAM). Instead of using a single OBJT_DEVICE object and passing the physaddr via the offset as a hack, create a new sglist and OBJT_SG object for each mmap request. The requested memory attribute is applied to the object thus affecting all pages mapped by the request. Sponsored by: Chelsio Notes: svn path=/stable/9/; revision=287637

| | | | | | | | | | | | | Fix broken implementation of "kvasprintf()" function by adding missing kmalloc() call. Make function global instead of static inline to fix compiler warnings about passing variable argument lists to inline functions.

| | | | | | | | | | | | | | | | | | | | | | | | r280210, r280764 and r280768: Update the Linux compatibility layer: - Add more functions. - Add some missing includes which are needed when the header files are not included in a particular order. - The kasprintf() function cannot be inlined due to using a variable number of arguments. Move it to a C-file. - Fix problems about 32-bit ticks wraparound and unsigned long conversion. Jiffies or ticks in FreeBSD have integer type and are not long. - Add missing "order_base_2()" macro. - Fix BUILD_BUG_ON() macro. - Declare a missing symbol which is needed when compiling without -O2 - Clean up header file inclusions in the linux/completion.h, linux/in.h and linux/fs.h header files.

* MFC r276749:Hans Petter Selasky2015-01-131-0/+8
| | | | | | | | | | | | | | | | | | | | | | Fixes and updates for the Linux compatibility layer: - Remove unsupported "bus" field from "struct pci_dev". - Fix logic inside "pci_enable_msix()" when the number of allocated interrupts are less than the number of available interrupts. - Update header files included from "list.h". - Ensure that "idr_destroy()" removes all entries before destroying the IDR root node(s). - Set the "device->release" function so that we don't leak memory at device destruction. - Use FreeBSD's "log()" function for certain debug printouts. - Put parenthesis around arguments inside the min, max, min_t and max_t macros. - Make sure we don't leak file descriptors by dropping the extra file reference counts done by the FreeBSD kernel when calling falloc() and fget_unlocked().

| | | | | | | | | | | | Store a reference to the vnode associated with a file descriptor in the linux_file structure and use it instead of directly accessing td_fpop when destroying the linux_file structure. The td_fpop pointer is not valid when a cdevpriv destructor is run, and the type-specific close method has already been called, so f_vnode may not be valid (and the vnode might have been recycled without our own reference).
