| | | | | | | | | | | | | | | | | 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().

| | | | | | | | | | | | | | | | | | | | | | | Update the LinuxKPI: - Add more functions and types. - Implement ACCESS_ONCE(), WRITE_ONCE() and READ_ONCE(). - Implement sleepable RCU mechanism using shared exclusive locks. - Minor workqueue cleanup: - Make some functions global instead of inline to ease debugging. - Fix some minor style issues. - In the zero delay case in queue_delayed_work() use the return value from taskqueue_enqueue() instead of reading "ta_pending" unlocked and also ensure the callout is stopped before proceeding. - Implement drain_workqueue() function. - Reduce memory consumption when allocating kobject strings in the LinuxKPI. Compute string length before allocating memory instead of using fixed size allocations. Make kobject_set_name_vargs() global instead of inline to save some bytes when compiling.

| | | | | | | | | | | | | | | | | | 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/10/; revision=287637

* Split the pagequeues per NUMA domains, and split pageademon processKonstantin Belousov2013-08-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | into threads each processing queue in a single domain. The structure of the pagedaemons and queues is kept intact, most of the changes come from the need for code to find an owning page queue for given page, calculated from the segment containing the page. The tie between NUMA domain and pagedaemon thread/pagequeue split is rather arbitrary, the multithreaded daemon could be allowed for the single-domain machines, or one domain might be split into several page domains, to further increase concurrency. Right now, each pagedaemon thread tries to reach the global target, precalculated at the start of the pass. This is not optimal, since it could cause excessive page deactivation and freeing. The code should be changed to re-check the global page deficit state in the loop after some number of iterations. The pagedaemons reach the quorum before starting the OOM, since one thread inability to meet the target is normal for split queues. Only when all pagedaemons fail to produce enough reusable pages, OOM is started by single selected thread. Launder is modified to take into account the segments layout with regard to the region for which cleaning is performed.

Now every descriptor has set of its own capability rights. - The cap_new(2) system call is left, but it is no longer documented and should not be used in new code. - The new syscall cap_rights_limit(2) should be used instead of cap_new(2), which limits capability rights of the given descriptor without creating a new one. - The cap_getrights(2) syscall is renamed to cap_rights_get(2). - If CAP_IOCTL capability right is present we can further reduce allowed ioctls list with the new cap_ioctls_limit(2) syscall. List of allowed ioctls can be retrived with cap_ioctls_get(2) syscall. - If CAP_FCNTL capability right is present we can further reduce fcntls that can be used with the new cap_fcntls_limit(2) syscall and retrive them with cap_fcntls_get(2). - To support ioctl and fcntl white-listing the filedesc structure was heavly modified. - The audit subsystem, kdump and procstat tools were updated to recognize new syscalls. - Capability rights were revised and eventhough I tried hard to provide backward API and ABI compatibility there are some incompatible changes that are described in detail below: CAP_CREATE old behaviour: - Allow for openat(2)+O_CREAT. - Allow for linkat(2). - Allow for symlinkat(2). CAP_CREATE new behaviour: - Allow for openat(2)+O_CREAT. Added CAP_LINKAT: - Allow for linkat(2). ABI: Reuses CAP_RMDIR bit. - Allow to be target for renameat(2). Added CAP_SYMLINKAT: - Allow for symlinkat(2). Removed CAP_DELETE. Old behaviour: - Allow for unlinkat(2) when removing non-directory object. - Allow to be source for renameat(2). Removed CAP_RMDIR. Old behaviour: - Allow for unlinkat(2) when removing directory. Added CAP_RENAMEAT: - Required for source directory for the renameat(2) syscall. Added CAP_UNLINKAT (effectively it replaces CAP_DELETE and CAP_RMDIR): - Allow for unlinkat(2) on any object. - Required if target of renameat(2) exists and will be removed by this call. Removed CAP_MAPEXEC. CAP_MMAP old behaviour: - Allow for mmap(2) with any combination of PROT_NONE, PROT_READ and PROT_WRITE. CAP_MMAP new behaviour: - Allow for mmap(2)+PROT_NONE. Added CAP_MMAP_R: - Allow for mmap(PROT_READ). Added CAP_MMAP_W: - Allow for mmap(PROT_WRITE). Added CAP_MMAP_X: - Allow for mmap(PROT_EXEC). Added CAP_MMAP_RW: - Allow for mmap(PROT_READ | PROT_WRITE). Added CAP_MMAP_RX: - Allow for mmap(PROT_READ | PROT_EXEC). Added CAP_MMAP_WX: - Allow for mmap(PROT_WRITE | PROT_EXEC). Added CAP_MMAP_RWX: - Allow for mmap(PROT_READ | PROT_WRITE | PROT_EXEC). Renamed CAP_MKDIR to CAP_MKDIRAT. Renamed CAP_MKFIFO to CAP_MKFIFOAT. Renamed CAP_MKNODE to CAP_MKNODEAT. CAP_READ old behaviour: - Allow pread(2). - Disallow read(2), readv(2) (if there is no CAP_SEEK). CAP_READ new behaviour: - Allow read(2), readv(2). - Disallow pread(2) (CAP_SEEK was also required). CAP_WRITE old behaviour: - Allow pwrite(2). - Disallow write(2), writev(2) (if there is no CAP_SEEK). CAP_WRITE new behaviour: - Allow write(2), writev(2). - Disallow pwrite(2) (CAP_SEEK was also required).

* Redo r242842, now actually fixing the warnings, as follows:Dimitry Andric2012-11-121-4/+6
| | | | | | | | | | | | | | | | | | | - In sys/ofed/drivers/infiniband/core/cma.c, an enum struct member is interpreted as an int, so cast it to an int. - In sys/ofed/drivers/infiniband/core/ud_header.c, initialize the packet_length variable in ib_ud_header_init(), to prevent undefined behaviour. - In sys/ofed/drivers/infiniband/ulp/sdp/sdp_rx.c, call rdma_notify() with the correct enum type and value. - In sys/ofed/include/linux/pci.h, change the PCI_DEVICE and PCI_VDEVICE macros to use C99 struct initializers, so additional members can be overridden.
