3036 | Here is a matrix of mmap possibilities: | |
3037 | mmap private not fixed | |
3038 | mmap private fixed at somewhere currently unmapped | |
3039 | mmap private fixed at somewhere already mapped | |
3040 | mmap shared not fixed | |
3041 | mmap shared fixed at somewhere currently unmapped | |
3042 | mmap shared fixed at somewhere already mapped | |
3043 | For private mappings, we should verify that changes cannot be read() | |
3044 | back from the file, nor mmap's back from the file at a different | |
3045 | address. (There have been systems where private was not correctly | |
3046 | implemented like the infamous i386 svr4.0, and systems where the | |
3047 | VM page cache was not coherent with the filesystem buffer cache | |
3048 | like early versions of FreeBSD and possibly contemporary NetBSD.) | |
3049 | For shared mappings, we should conversely verify that changes get | |
3050 | propogated back to all the places they're supposed to be. | |
3051 | ||
3052 | Grep wants private fixed already mapped. | |
3053 | The main things grep needs to know about mmap are: | |

3055 | * how to use it (BSD variants) */ | |
