2015-11-24hotroot is calculated late in fsck_ffs, so defer the pledge.Theo de Raadt
2015-11-23Cannot pledge() in the hotroot caseTheo de Raadt
Discovered by krw
2015-11-23Use pledge "disklabel" as needed. The theory here is these tools become moreTheo de Raadt
resistant against memory correctup, if a corrupt filesystem is given to them. ok krw
2015-10-15corrects pledge code for fsck_ffs and fsck_ext2fsSebastien Marie
on filesystem error, fsck will try to display username of inode, resulting need of "getpw" for not SMALL version. add a missed (?) -DSMALL in distrib/special/ for fsck_ffs and fsck_ext2fs found by hard way by ajacoutot@ OK millert@
2015-10-15fsck_ffs has a ^T signal handler which opens /dev/tty late. Hoist thatTheo de Raadt
opening to before the pledge, and cache the fd. looked over by millert
2015-10-14Since the fsck_* programs now only handle one filesystem, this createsTheo de Raadt
a point where open() and disklabel reading have completed. After that point, pledge "stdio". As a result, an fsck of a hostile partition (noone ever does that, or do they? :) is done by a program with SUBSTANTIALLY less system call exposure. ok semarie
2015-10-14Only accept one filesystem/device as argument for checking. Few peopleTheo de Raadt
will be calling these directly, and not for the multiple filesystem case. fsck(8) is generally the parent and will handle things. ok semarie; this change will also help a goal jsing has

2015-01-16Replace <sys/param.h> with <limits.h> and other less dirty headers whereTheo de Raadt
possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)

2014-09-06inodesc.id_entryno holds a file size, so upgrade it from int to u_int64_t;Philip Guenther
this fixes handling of very large files on FFS2. Correct a copy-n-pasto that rendered useless the check for allocated fragmented that are marked free in the bitmap. allocdir() returns an inode number, so return an ino_t. sizeof()*N should be printed with %zu, while direct and indirect block numbers should be cast to (long long) use %lld inodesc.id_entryno fix based on a diff from David Vasek <vasek@fido.cz> ok krw@ otto@

2014-05-29fsck should use the same values in checking as newfs does in creatingKenneth R Westerback
a filesystem. fs_nspf and its derivitives like fs_spc are DEV_BSIZE values, not actual hardware disk sector values. Adjust initializations accordingly. Tweak header and man page comments to make the DEV_BSIZE'ness more obvious for future spelunkers. No-op for DEV_BSIZE (a.k.a. 512-byte) sector devices but should help checking filesystems on, e.g., 4k-byte sector devices. ok jmc@ on the man page tweaks.
2014-05-24Use consistent format specifiers (%lld) and casts (long long) whenKenneth R Westerback
printing out block numbers and sector numbers. Make output verbiage consistent. -Wall happier. Original diff and ok chl@

2014-05-20As suggested by guenther@ and millert@, replace seek+[read|write] withKenneth R Westerback
p[read|write]. Makes the code much clearer by eliminating extra error checking and verbiage. No intentional functional change. Tweaks by and ok guenther@
2014-05-09Modernize spelling. 'Mimick' -> 'Mimic' in comment.Kenneth R Westerback
2014-05-09Fix '-b' option to work with the superblock locations output by newfsKenneth R Westerback
on 4096-byte sector disks. No-op on 512-byte sector disks. Adhering to the bedrock idea that ffs will *never* use anything but 512-byte block disk addressing (a.k.a. daddr_t), and believing that the 'fake' bread()/bwrite() functions should always be using 512-btye block numbers like their kernel big brothers, nuke the computed dev_bsize and use DEV_BSIZE for conversions to/from byte offsets. Spotted and various fixes tested by David Vasek. Still to fix: scanning for superblocks on 4K disks. ok otto@
2013-11-22Kirk was being waaaay too chummy with the compiler when he trustedPhilip Guenther
it to not optimize away a comparison against NULL-1. Add (unsigned char) casts for some ctype calls. Teach fsck_ext2fs about MAXPARTITIONS, letting it operate on partitions 'i' through 'p'. ok deraadt@ millert@ otto@

for defines fragnum, fsbtodb, cgsblock, and cgdmin.
2013-11-02No need to cast constants or simple variables to (daddr_t). UseKenneth R Westerback
(u_int64_t) instead of (daddr_t) when casting a variable in an expression passed to DL_SETDSIZE(). Change a variable counting open files from daddr_t to int64_t. ok deraadt@ with the tweak to fix that pesky expression.
2013-11-01Sprinkle (long long) casts where %lld is being used to print daddr_tKenneth R Westerback

2010-06-15When fsck_ffs is used with disklabel UIDs the hot root test fails inJoel Sing
blockcheck() since we try to stat() the UID. This means that we fail to reload the mount if we have indeed cleaned the read-only root file system. To avoid this, rerun blockcheck() if the real name is different to the original device name, once we have opened the device with opendev(3). ok krw@ thib@
