 1.24  17-Nov-2022  chs Restore backward compatibility of UFS2 with previous NetBSD releases by
disabling support in UFS2 for extended attributes (including ACLs).
Add a new variant of UFS2 called "UFS2ea" that does support extended attributes.
Add new fsck_ffs operations "-c ea" and "-c no-ea" to convert file systems
from UFS2 to UFS2ea and vice-versa (both of which delete all existing extended
attributes in the process).
 1.23  01-Mar-2019  christos Use getfsspecname() to fill the filesystem argument in dumpdates.
While here, make sure that the error strings terminate with newline
consistently, and add a function that adds the system error string.
 1.22  23-Jun-2013  dholland branches: 1.22.20; 1.22.28;
fsbtodb() -> FFS_FSBTODB(), EXT2_FSBTODB(), or MFS_FSBTODB()
dbtofsb() -> FFS_DBTOFSB() or EXT2_DBTOFSB()

(Christos already did the lfs ones a few days back)
 1.21  19-Jun-2013  dholland Rename ambiguous macros:
MAXDIRSIZE -> UFS_MAXDIRSIZE or LFS_MAXDIRSIZE
NINDIR -> FFS_NINDIR, EXT2_NINDIR, LFS_NINDIR, or MFS_NINDIR
INOPB -> FFS_INOPB, LFS_INOPB
INOPF -> FFS_INOPF, LFS_INOPF
blksize -> ffs_blksize, ext2_blksize, or lfs_blksize
sblksize -> ffs_blksize

These are not the only ambiguously defined filesystem macros, of
course, there's a pile more. I may not have found all the ambiguous
definitions of blksize(), too, as there are a lot of other things
called 'blksize' in the system.
 1.20  22-Jan-2013  dholland Stuff UFS_ in front of a few of ufs's symbols to reduce namespace
pollution. Specifically:
ROOTINO -> UFS_ROOTINO
WINO -> UFS_WINO
NXADDR -> UFS_NXADDR
NDADDR -> UFS_NDADDR
NIADDR -> UFS_NIADDR
MAXSYMLINKLEN -> UFS_MAXSYMLINKLEN
MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency)

Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have
the same values in ext2fs and ffs.

No functional change intended.
 1.19  13-Jan-2013  dholland Use static; remove unused global var this uncovered.
 1.18  20-Jul-2008  lukem branches: 1.18.18; 1.18.24;
Remove the \n and tabs from the __COPYRIGHT() strings.
(Tweak some to use a consistent format.)
 1.17  18-Dec-2006  christos branches: 1.17.12; 1.17.16;
Convert a couple of "(void)&" constructs to volatile.
Flag various unused parameters in restore and dump so that these will
compile with -Wextra. (Note: restore uses some stuff from dump.)
 1.16  27-Mar-2004  dsl Don't require ffsv2 fs have FS_FLAGS_UPDATED set
 1.15  24-Mar-2004  ws After determining whether the filesystem is byte swapped,
we better return that fact to the caller.
 1.14  21-Mar-2004  dsl When searching for the superblock, don't pick an ffsv1 superblock from the
location where we expect to find an ffsv2 superblock.
It could be the first alternate for a ffsv1 filesystem with 64k blocks.
Fixes part of PR kern/24809
 1.13  07-Aug-2003  agc Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22308, verified by myself.
 1.12  02-Apr-2003  fvdl Add support for UFS2. UFS2 is an enhanced FFS, adding support for
64 bit block pointers, extended attribute storage, and a few
other things.

This commit does not yet include the code to manipulate the extended
storage (for e.g. ACLs), this will be done later.

Originally written by Kirk McKusick and Network Associates Laboratories for
FreeBSD.
 1.11  24-Jan-2003  fvdl Bump daddr_t to 64 bits. Replace it with int32_t in all places where
it was used on-disk, so that on-disk formats remain the same.
Remove ufs_daddr_t and ufs_lbn_t for the time being.
 1.10  23-Dec-2001  lukem unifdef sunos
 1.9  22-Dec-2001  lukem - use correct type for minTime in findlru() (size_t instead of int)
- clean up whitespace
 1.8  01-Nov-2001  lukem fix -Wshadow warnings
 1.7  17-Aug-2001  lukem remove third argument (`int ns') from ffs_sb_swap(), and let ffs_sb_swap()
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.
 1.6  14-Aug-2001  lukem s/filesystem/file system/dump.h
 1.5  28-May-2001  lukem unifdef !__STDC__ (missed in previous)
 1.4  27-May-2001  lukem knf to ansi
 1.3  01-Oct-1999  perseant branches: 1.3.4; 1.3.8;
Working version of aborted dump{,_lfs} join.
 1.2  30-Sep-1999  perseant Back out changes made on the 29th, not at all the changes I intended to commit.
(I don't know how I did it though ... I'll figure it out tonight.)
I'll reapply this, in a working form, this evening.
 1.1  29-Sep-1999  perseant Adapt dump(8) to use filestore-independent (but still ufs-specific)
replacements for NINDIR, fsbtodb, etc. Create dump_lfs by adding a few
LFS-filestore-specific routines. As described in PR#8317.
 1.3.8.3  17-Jan-2002  he Pull up revision 1.7 (requested by he):
Fix compile problem after last round of pullups.
The already-pulled-up 1.7 was inadvertently undone by the previous patch.
 1.3.8.2  16-Jan-2002  he Pull up revisions 1.9-1.10 (via patch, requested by bouyer):
Various fixes:
o Fix error if first tape is write-protected; fixes PR#4754 and PR#6098
o Make error codes conform to manual page
o Use \a to make noise
o Fix estimated number of tapes for huge dumps to cartridges
o Use <sys/queue.h> SLIST_* macros instead of homegrown variants
o Do not exit if unable to read/create /etc/dumpdates
o Support output (tape) device returning ENOSPC for end-of-media on write
o Don't dump core if SIGINFO is received before 1 second has elapsed
o Only process SIGINFO in currently active child
o Ensure current (sub)block isn't past end of file system -- fixes
"spins forever but does nothing" bug.
o Some other minor fixes (types, whitespace, KNF, unifdef sunos, ...)
 1.3.8.1  25-Nov-2001  he Pull up revision 1.7 (requested by lukem):
Call ffs_sb_swap() with the correct arguments. Fixes problems
with using other-endian file systems.

Document what rdump is (was once) for. PR 53442.

Use getfsspecname() to fill the filesystem argument in dumpdates.
While here, make sure that the error strings terminate with newline
consistently, and add a function that adds the system error string.

Add -U flag to dump(8) and dump_lfs(8) to specify dumpdates entry
This address situations where dump(8) cannot figure out the device being
dumped. It also allows tracking of subvolume dumps by using virtual
device as dumpdates entry.

Bump date for previous.
