This code has suffered severe bitrot and is highly + Linux specific. Highlights include using hardcoded major/minor device + numbers to classify a device, and using 8 bits major/minor numbers that + have become obsolete a long time ago and thus often misidentifying a + device. + + The overhauled implementation is now in src/device_info.c and makes use + of libudev (optional, recommended) and libblkid (required) to probe the + device and where Linux ioctls are required it provides fallbacks and + does not attempt to call these on non-Linux systems. The FAT parameter + selection has been unified and simplified in the process. + + A new executable testdevinfo has been added that gets built but not + automatically installed. It takes one file name, uses the same probing + as mkfs.fat would with verbose messages enabled and displays the + results. + + Signed-off-by: Andreas Bombe + +commit 53eddfc +Author: Andreas Bombe +Date: Sat Sep 12 02:54:33 2015 +0200 + + Die on out of range cluster values in set_fat()/get_fat() + + To prevent bugs caused by FAT corruption inside fsck to go unnoticed, + add a check against out of range requested cluster values in get_fat() + and against out of range cluster to change and new cluster value in + set_fat(). + + When an invalid cluster value is detected, these functions now die() + with an "internal error" message. + + Signed-off-by: Andreas Bombe + +commit 456767b +Author: Andreas Bombe +Date: Mon Sep 14 00:33:49 2015 +0200 + + configure.ac: Use AS_HELP_STRING to format option help + + Signed-off-by: Andreas Bombe + +commit 3cfb479 +Author: Andreas Bombe +Date: Mon Sep 14 00:30:40 2015 +0200 + + version.h: Use @configure_input@ autoconf variable in boilerplate + + Signed-off-by: Andreas Bombe + +commit 41ef834 +Author: Andreas Bombe +Date: Mon Sep 14 00:29:27 2015 +0200 + + .gitignore: Add TAGS in addition to tags + + Signed-off-by: Andreas Bombe + +commit bdc3d2a +Author: Andreas Bombe +Date: Fri Sep 11 20:28:12 2015 +0200 + + Rename clusters field in DOS_FS struct + + Rename it to data_clusters to prevent mistaking the clusters field of + the DOS_FS struct as the total number of FAT entries instead of the + number of data clusters (two less than the number of entries). + + Signed-off-by: Andreas Bombe + +commit 0790812 +Author: Andreas Bombe +Date: Fri Sep 11 19:47:29 2015 +0200 + + set_fat(): Fix off-by-2 error leading to corruption in FAT12 + + In FAT12 two 12 bit entries are combined to a 24 bit value (three + bytes).
