(fhandler_dev_zero::munmap): Ditto. (fhandler_dev_zero::msync): Ditto. (fhandler_dev_zero::fixup_mmap_after_fork): Ditto. * mmap.cc: Implement anonymous mapping using fhandler_dev_zero class. Implement private anonymous maps using VirtualAlloc/VirtualFree. Fix or add some more comments. (fh_paging_file): Change to type fhandler_dev_zero. (priv): New static inline function to avoid having lots of flag bit tests in the code. Use throughout were appropriate. (fixed): Ditto. (anonymous): Ditto. (noreserve): Ditto. (autogrow): Ditto. (gen_protect): Never generate PAGE_WRITECOPY protection for private anonymous maps. (gen_access): Drop FILE_MAP_EXECUTE handling since it's not supported correctly on 9x. (VirtualProt9x): Move comment from mmap64 here. (mmap_record::mmap_record): Gegerate correct device entry for anonymous maps, though unused right now. (mmap_record::priv): Call global priv function. (mmap_record::fixed): Call global fixed function. (mmap_record::anonymous): Call global anonymous function. (mmap_record::noreserve): Call global noreserve function. (mmap_record::autogrow): Call global autogrow function. (list::anonymous): New method. Use throughout were appropriate. (mmap_record::compatible_flags): Drop now useless ifdef. (mmap_record::alloc_page_map): Accomodate private anonymous maps. (mmap_record::map_pages): Accomodate MAP_NORESERVE mappings. (mmap_record::unmap_pages): Accomodate private anonymous maps. (mmap64): Simplify argument check. Don't remove the MAP_PRIVATE flag for anonymous mappings on 9x anymore since that's now handled gracefully. (mprotect): Accomodate MAP_NORESERVE mappings. Fix case when non-mmap areas are just MEM_RESERVEd. (fhandler_dev_zero::mmap): Implement anonymous mapping here. (fhandler_dev_zero::munmap): Ditto. (fhandler_dev_zero::msyn): Ditto. (fhandler_dev_zero::fixup_mmap_after_fork): Ditto. (fixup_mmaps_after_fork): Accomodate private anonymous maps. Enhance debug output in case VirtualProtect fails. * include/sys/mman.h: Really define MAP_NORESERVE now. |
