determine the endianness of the `struct fs *o' superblock from o->fs_magic and set needswap as necessary, rather than trusting the caller to get it right. invariably, almost every caller of ffs_sb_swap() was calling it with ns set to the wrong value for ns anyway! ansi KNF ffs_bswap.c declarations whilst here. this fixes all sorts of problems when trying to use other-endian file systems, notably the kernel trying to access memory *way* off, possibly corrupting or panicing, and userland programs SEGVing and/or corrupting things (e.g, "fsck_ffs -B" to swap a file system endianness). whilst the previous rev of ffs_bswap.c (1.10, 2000/12/23) made this problem worse, i suspect that the problem was always there and previous versions just happened not to trash things at the wrong time. FFS_EI should now be a lot more stable. |
