3104 | Here is a matrix of mmap possibilities: | |
3105 | mmap private not fixed | |
3106 | mmap private fixed at somewhere currently unmapped | |
3107 | mmap private fixed at somewhere already mapped | |
3108 | mmap shared not fixed | |
3109 | mmap shared fixed at somewhere currently unmapped | |
3110 | mmap shared fixed at somewhere already mapped | |
3111 | For private mappings, we should verify that changes cannot be read() | |
3112 | back from the file, nor mmap's back from the file at a different | |
3113 | address. (There have been systems where private was not correctly | |
3114 | implemented like the infamous i386 svr4.0, and systems where the | |
3115 | VM page cache was not coherent with the filesystem buffer cache | |
3116 | like early versions of FreeBSD and possibly contemporary NetBSD.) | |
3117 | For shared mappings, we should conversely verify that changes get | |
3118 | propogated back to all the places they're supposed to be. | |
3119 | ||
3120 | Grep wants private fixed already mapped. | |
3121 | The main things grep needs to know about mmap are: | |
3122 | * does it exist and is it safe to write into the mmap'd area | |
3123 | * how to use it (BSD variants) */ | |
