2007-05-18Fix mismerge; remove statement without effect. OK otto@ pedro@Todd C. Miller
2007-05-11pass the right size arg to memset, otherwise we end up with aOtto Moerbeek
partially initialized summary info struct. ok millert@ pedro@
2007-05-05Do not rely on fs_cpg; this is especially important for ffs2 whichTodd C. Miller
does not use fs_cpg at all. From FreeBSD. OK otto@
2007-04-23Remove 'cg_space' from 'struct cg'. Due to the alignment on 64-bitPedro Martelletto
architectures, CGSIZE() was returning something sligthly over one block. The 'new' fsck would round this value up to a fragment boundary, and end up trying to access memory beyond allocated space. From mickey@, okay pedro@, millert@ and otto@.
2007-04-21use the correct size arg to memcmp when checking fs_cstotal.Otto Moerbeek
now jmc does not use 8TB in /tmp anymore. ok pedro@
2007-04-18When trying to read the primary superblock, do not accidentially readOtto Moerbeek
a ffs1 alternate sb at the primary ffs2 sb location. Use the same test as the kernel does. ok millert@ pedro@
2007-04-10Add support for checking ffs2 filesystems. From pedro@ based onTodd C. Miller
the ufs2 changes in FreeBSD by Kirk Mckusick.
2007-03-19be a tiny little bit more verbose when encoutering bad block or fragmentOtto Moerbeek
sizes; requested by mickey@
2007-03-19Add FFS2 fields to the superblock, change file system tools to keepPedro Martelletto
accessing FFS1 fields, okay art@, quite some testing by ckuethe@, simon@ and thib@, thanks.
2007-03-18there's no way we're going to be able to handle illegal block orOtto Moerbeek
fragment sizes, so just make those conditions fatal errors and tell the calling code to go look for alternate superblocks. ok millert@
2007-03-15Check for cg_irotor and cg_frotor being negative, okay millert@ deraadt@Pedro Martelletto
2007-02-16Fix a row of bugs in the code that computes the alternate superblockOtto Moerbeek
locations based on the disklabel. - unit bug: disklabel size is in sectors, but superblock fs size is in fragments. - The disklabel contains the maximum superblock size, not the actual as used by newfs. - problem is that mkfs reduces track/sector and secors/track to make the cylindergroup fit in a fs block. In this case the values in the disklabel do not predict what's in the superblock. This fixes all these problems. It correctly predicts the location of all superblocks on all my filesystems I have online (sized between 100MB and 1000GB). Also tested with filesystems with different block and fragment sizes. Written this with a goto to make the diff easier to read. ok krw@ deraadt@
2007-02-13"Fix" a horrible signal handler. ckfini() breaks all the rules forOtto Moerbeek
signal handlers, calling free() and not being reentrant. This commit fixes to most importamt problem (^C on the "MARK FILESYSTEM CLEAN?" question causes a double free), but actually SIGINT handling should be completely rewritten. ok millert@ deraadt@
2007-02-13Do some extra validation of the superblock, otherwise a corruptOtto Moerbeek
superblock might lead to crashes or other mishap. Now my fuzzed fs images no longer crash fsck_ffs. ok mickey@ pedro@ millert@
2007-02-12remsize must be signed to avoid wrapping around to some huge number.Otto Moerbeek
Solves a case were fsck_ffs was causing a segv. If it didn't do that it would have mangled the filesystem later, very probably. Diff from FreeBSD; ok millert@ pedro@
2007-02-12detect truncation of block number, which can happen which trashedOtto Moerbeek
inodes; ok pedro@ millert@
2007-02-12max partition letter is 'a' + MAXPARTITIONS - 1, not 'h'. ok (andOtto Moerbeek
help) miod@
2007-02-09fix a fd leak that happens whe checking multiple file systems and someOtto Moerbeek
of them are clean. ok pedro@ millert@
2007-02-08Plug some mem leaks that occur when checking multiple file systems in aOtto Moerbeek
row. ok beck@ pedro@ millert@
2007-02-08A corrrup inode might lead to preposterous dir sizes. So check theOtto Moerbeek
size to avoid a negative lastbn which might cause a segv or heap corruption. With help from mickey@; ok mickey@ pedro@ millert@
2007-01-24A reallocated root directory gets ownership of the fsck process.Alexander Bluhm
If lost+found is created, it gets ownership of the root directory. ok pedro
2006-04-27Avoid spurious 'summary information bad' warnings, okay tedu@Pedro Martelletto

2005-06-16bye bye whiteoutsTodd C. Miller
2005-04-16Since the return value from the *_info functions is only actually used as aTodd C. Miller
boolean, make it so. OK deraadt@
2005-04-16while snprintf and strlcpy and strlcat have this nice >buflen API (and theTheo de Raadt
-1 mess as well), it is probably not wise to make other functions do the same thing. make them return strlen(). ok uwe marco

2005-02-03- simplify, normalize, and sync usage/synopsis formsJared Yanovich
- filesystem -> file system, for consistency - indent sections where applicable - mdoc, punctuation, grammar, etc. fixes - document SIGINFO to fsck_ffs - unify description of -n among documents - sprinkle xrefs all around - move parts relevant to fsck.8 from fsck_ffs.8 parts from NetBSD ok jmc
2005-02-02- syncs are done by a kernel thread, not update(8)Jared Yanovich
- halting flushes the fs cache to disk, no need to run explicitly - other minor tweaks (grammar, punctuation, etc.) ok jmc
