ufs: fixed signed/unsigned bugs affecting large file systems
Apply these commits from FreeBSD:
commit e870d1e6f97cc73308c11c40684b775bcfa906a2 Author: Kirk McKusick <mckusick@FreeBSD.org> Date: Wed Feb 10 20:10:35 2010 +0000
This fix corrects a problem in the file system that treats large inode numbers as negative rather than unsigned. For a default (16K block) file system, this bug began to show up at a file system size above about 16Tb.
To fully handle this problem, newfs must be updated to ensure that it will never create a filesystem with more than 2^32 inodes. That patch will be forthcoming soon.
Reported by: Scott Burns, John Kilburg, Bruce Evans Followup by: Jeff Roberson PR: 133980 MFC after: 2 weeks
commit 81479e688b0f643ffacd3f335b4b4bba460b769d Author: Kirk McKusick <mckusick@FreeBSD.org> Date: Thu Feb 11 18:14:53 2010 +0000
One last pass to get all the unsigned comparisons correct.
In additional to the changes from FreeBSD, this commit includes quite a few related changes to appease -Wsign-compare.

branches: 1.70.2; 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).

branches: 1.65.6; Add the FS_SUJ flag for journaled softupdates from FreeBSD.
This conflicts with our flag for FS_INDEXDIRS. Apparently FreeBSD changed that arbitrarily on their end when implementing journaled softupdates, so follow their lead.
Unfortunately, the new value they use for FS_INDEXDIRS conflicts with our flag FS_DOQUOTA2 for 64-bit quotas. Since the only thing in our tree that knows about FS_INDEXDIRS is dumpfs (for printing it), leave FS_INDEXDIRS commented out.
Also add FS_NFS4ACLS from FreeBSD, commented out because it conflicts with our FS_DOWAPBL, and FS_TRIM.
(We could honor FS_TRIM as we have code for doing that; however I'm not sure why FreeBSD chose to make it an on-disk flag instead of e.g. a mount option and it seems problematic to me. In any case, not in this commit.)
Also see a post I just made in tech-kern about the flag conflicts.

branches: 1.64.2; Stick ffs_ in front of the following macros: fragstoblks() blkstofrags() fragnum() blknum()
to finish the job of distinguishing them from the lfs versions, which Christos renamed the other day.
I believe this is the last of the overtly ambiguous exported symbols from ffs... or at least, the last of the ones that conflicted with lfs. ffs still pollutes the C namespace very broadly (as does ufs) and this needs quite a bit more cleanup.
XXX: boo on macros with lowercase names. But I'm not tackling that just yet.

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.

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.

branches: 1.56.4; 1.56.8; merge the bouyer-quota2 branch. This adds a new on-disk format to store disk quota usage and limits, integrated with ffs metadata. Usage is checked by fsck_ffs (no more quotacheck) and is covered by the WAPBL journal. Enabled with kernel option QUOTA2 (added where QUOTA was enabled in kernel config files), turned on with tunefs(8) on a per-filesystem basis. mount_mfs(8) can also turn quotas on.
See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html for details.

branches: 1.55.4; 1.55.6; 1.55.8; Fix block shift to work with different device block sizes.
Unlike other filesystems this has some side issues because the shift values are stored in the superblock and because userland utitlies share the same fsbtodb macros.
-> the kernel now ignores the value stored in the superblock. -> the macro adaption is only done for defined(_KERNEL) code.

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.

Add support for the Apple UFS variation on ffs This is the bulk of PR #17345
The general approach is to use a run time deteriminable value for DIRBLKSIZ. Additional allowances are included for using MAXSYMLINKLEN with FS_42INODEFMT and a shift in the cylinder group cluster summary count array. Support is added for managing the Apple UFS volume label.

Bring over fixes from FreeBSD that weren't incorporated yet, mainly from Kirk McKusick. They implement taking pending block/inode frees into account for the sake of correct statfs() numbers, and adding a new softdep type (newdirblk) to correctly handle newly allocated directory blocks.
Minor additional changes: 1) swap the newly introduced fs_pendinginodes and fs_pendingblock fields in ffs_sb_swap, and 2) declare lkt_held in the debug version of the softdep lock structure volatile, as it can be modified from interrupt context #ifdef DEBUG.

branches: 1.20.2; Incorporate the enhanced ffs_dirpref() by Grigoriy Orlov, as found in FreeBSD (three commits; the initial work, man page updates, and a fix to ffs_reload()), with the following differences: - Be consistent between newfs(8) and tunefs(8) as to the options which set and control the tuning parameters for this work (avgfilesize & avgfpdir) - Use u_int16_t instead of u_int8_t to keep track of the number of contiguous directories (suggested by Chuck Silvers) - Work within our FFS_EI framework - Ensure that fs->fs_maxclusters and fs->fs_contigdirs don't point to the same area of memory
The new algorithm has a marked performance increase, especially when performing tasks such as untarring pkgsrc.tar.gz, etc.
The original FreeBSD commit messages are attached:
===== mckusick 2001/04/10 01:39:00 PDT Directory layout preference improvements from Grigoriy Orlov <gluk@ptci.ru>. His description of the problem and solution follow. My own tests show speedups on typical filesystem intensive workloads of 5% to 12% which is very impressive considering the small amount of code change involved.
------
One day I noticed that some file operations run much faster on small file systems then on big ones. I've looked at the ffs algorithms, thought about them, and redesigned the dirpref algorithm.
First I want to describe the results of my tests. These results are old and I have improved the algorithm after these tests were done. Nevertheless they show how big the perfomance speedup may be. I have done two file/directory intensive tests on a two OpenBSD systems with old and new dirpref algorithm. The first test is "tar -xzf ports.tar.gz", the second is "rm -rf ports". The ports.tar.gz file is the ports collection from the OpenBSD 2.8 release. It contains 6596 directories and 13868 files. The test systems are:
1. Celeron-450, 128Mb, two IDE drives, the system at wd0, file system for test is at wd1. Size of test file system is 8 Gb, number of cg=991, size of cg is 8m, block size = 8k, fragment size = 1k OpenBSD-current from Dec 2000 with BUFCACHEPERCENT=35
2. PIII-600, 128Mb, two IBM DTLA-307045 IDE drives at i815e, the system at wd0, file system for test is at wd1. Size of test file system is 40 Gb, number of cg=5324, size of cg is 8m, block size = 8k, fragment size = 1k OpenBSD-current from Dec 2000 with BUFCACHEPERCENT=50
You can get more info about the test systems and methods at: http://www.ptci.ru/gluk/dirpref/old/dirpref.html

"old dirpref" and "new dirpref" columns give a test time in seconds. speedup - speed increasement in times, ie. old dirpref / new dirpref.

Algorithm description
The old dirpref algorithm is described in comments:
/* * Find a cylinder to place a directory. * * The policy implemented by this algorithm is to select from * among those cylinder groups with above the average number of * free inodes, the one with the smallest number of directories. */
A new directory is allocated in a different cylinder groups than its parent directory resulting in a directory tree that is spreaded across all the cylinder groups. This spreading out results in a non-optimal access to the directories and files. When we have a small filesystem it is not a problem but when the filesystem is big then perfomance degradation becomes very apparent.
What I mean by a big file system ?
1. A big filesystem is a filesystem which occupy 20-30 or more percent of total drive space, i.e. first and last cylinder are physically located relatively far from each other. 2. It has a relatively large number of cylinder groups, for example more cylinder groups than 50% of the buffers in the buffer cache.
The first results in long access times, while the second results in many buffers being used by metadata operations. Such operations use cylinder group blocks and on-disk inode blocks. The cylinder group block (fs->fs_cblkno) contains struct cg, inode and block bit maps. It is 2k in size for the default filesystem parameters. If new and parent directories are located in different cylinder groups then the system performs more input/output operations and uses more buffers. On filesystems with many cylinder groups, lots of cache buffers are used for metadata operations.
My solution for this problem is very simple. I allocate many directories in one cylinder group. I also do some things, so that the new allocation method does not cause excessive fragmentation and all directory inodes will not be located at a location far from its file's inodes and data. The algorithm is: /* * Find a cylinder group to place a directory. * * The policy implemented by this algorithm is to allocate a * directory inode in the same cylinder group as its parent * directory, but also to reserve space for its files inodes * and data. Restrict the number of directories which may be * allocated one after another in the same cylinder group * without intervening allocation of files. * * If we allocate a first level directory then force allocation * in another cylinder group. */
My early versions of dirpref give me a good results for a wide range of file operations and different filesystem capacities except one case: those applications that create their entire directory structure first and only later fill this structure with files.
My solution for such and similar cases is to limit a number of directories which may be created one after another in the same cylinder group without intervening file creations. For this purpose, I allocate an array of counters at mount time. This array is linked to the superblock fs->fs_contigdirs[cg]. Each time a directory is created the counter increases and each time a file is created the counter decreases. A 60Gb filesystem with 8mb/cg requires 10kb of memory for the counters array.
The maxcontigdirs is a maximum number of directories which may be created without an intervening file creation. I found in my tests that the best performance occurs when I restrict the number of directories in one cylinder group such that all its files may be located in the same cylinder group. There may be some deterioration in performance if all the file inodes are in the same cylinder group as its containing directory, but their data partially resides in a different cylinder group. The maxcontigdirs value is calculated to try to prevent this condition. Since there is no way to know how many files and directories will be allocated later I added two optimization parameters in superblock/tunefs. They are:
int32_t fs_avgfilesize; /* expected average file size */ int32_t fs_avgfpdir; /* expected # of files per directory */
These parameters have reasonable defaults but may be tweeked for special uses of a filesystem. They are only necessary in rare cases like better tuning a filesystem being used to store a squid cache.
I have been using this algorithm for about 3 months. I have done a lot of testing on filesystems with different capacities, average filesize, average number of files per directory, and so on. I think this algorithm has no negative impact on filesystem perfomance. It works better than the default one in all cases. The new dirpref will greatly improve untarring/removing/coping of big directories, decrease load on cvs servers and much more. The new dirpref doesn't speedup a compilation process, but also doesn't slow it down.

===== iedowse 2001/04/23 17:37:17 PDT Pre-dirpref versions of fsck may zero out the new superblock fields fs_contigdirs, fs_avgfilesize and fs_avgfpdir. This could cause panics if these fields were zeroed while a filesystem was mounted read-only, and then remounted read-write.
Add code to ffs_reload() which copies the fs_contigdirs pointer from the previous superblock, and reinitialises fs_avgf* if necessary.

deprecate fs_fscktime; we never used it.
in an effort to maintain compatibility with freebsd/openbsd/whatever, i'm attempting to get the superblock format in sync, and freebsd uses the int32_t at this position for `fs_pendinginodes'.
if we ever decide to implement fscktime functionality, we'll: a) make sure to liaise with the other projects to reserve the same spare field b) actually implement the code this time ...
(this is also preparing us for other changes, like the new dirpref code)

Incorporate fix by iedowse @ FreeBSD to allow disks with large numbers of cylinder groups to work correctly, with minor modifications by me to work with our FFS_EI code. From the FreeBSD commit message:
The ffs superblock includes a 128-byte region for use by temporary in-core pointers to summary information. An array in this region (fs_csp) could overflow on filesystems with a very large number of cylinder groups (~16000 on i386 with 8k blocks). When this happens, other fields in the superblock get corrupted, and fsck refuses to check the filesystem.
Solve this problem by replacing the fs_csp array in 'struct fs' with a single pointer, and add padding to keep the length of the 128-byte region fixed. Update the kernel and userland utilities to use just this single pointer.
With this change, the kernel no longer makes use of the superblock fields 'fs_csshift' and 'fs_csmask'. Add a comment to newfs/mkfs.c to indicate that these fields must be calculated for compatibility with older kernels.

More fixes from FreeBSD (with changes): - Cast blk argument to lblktosize() to (off_t), to prevent 32 bit overflow. whilst almost every use in ffs used this for small blknos, there are potential issues, and it's safer this way. (as discussed with chuq) - Use 64bit (off_t) math to calculate if we have hit our freespace() limit. Necessary for coherent results on filesystems bigger than 0.5Tb. - Use lblktosize() in blksize() and dblksize(), to make it obvious what's happening - Remove sblksize() - nothing uses it

Add support for reading/writing FFS in non-native byte order, conditioned to "options FFS_EI". The superblock and inodes (without blk addr) are byteswapped at disk read/write time, other metadatas are byteswapped when used (as they are acceeded directly in the buffer cache). This required the addition of a "um_flags" field to struct ufsmount. ffs_bswap.c contains superblock and inode byteswap routines also used by userland utilities.

ufs: fixed signed/unsigned bugs affecting large file systems
Apply these commits from FreeBSD:
commit e870d1e6f97cc73308c11c40684b775bcfa906a2 Author: Kirk McKusick <mckusick@FreeBSD.org> Date: Wed Feb 10 20:10:35 2010 +0000
This fix corrects a problem in the file system that treats large inode numbers as negative rather than unsigned. For a default (16K block) file system, this bug began to show up at a file system size above about 16Tb.
To fully handle this problem, newfs must be updated to ensure that it will never create a filesystem with more than 2^32 inodes. That patch will be forthcoming soon.
Reported by: Scott Burns, John Kilburg, Bruce Evans Followup by: Jeff Roberson PR: 133980 MFC after: 2 weeks
commit 81479e688b0f643ffacd3f335b4b4bba460b769d Author: Kirk McKusick <mckusick@FreeBSD.org> Date: Thu Feb 11 18:14:53 2010 +0000

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.

branches: 1.65.6; Add the FS_SUJ flag for journaled softupdates from FreeBSD.
This conflicts with our flag for FS_INDEXDIRS. Apparently FreeBSD changed that arbitrarily on their end when implementing journaled softupdates, so follow their lead.
Unfortunately, the new value they use for FS_INDEXDIRS conflicts with our flag FS_DOQUOTA2 for 64-bit quotas. Since the only thing in our tree that knows about FS_INDEXDIRS is dumpfs (for printing it), leave FS_INDEXDIRS commented out.
Also add FS_NFS4ACLS from FreeBSD, commented out because it conflicts with our FS_DOWAPBL, and FS_TRIM.
(We could honor FS_TRIM as we have code for doing that; however I'm not sure why FreeBSD chose to make it an on-disk flag instead of e.g. a mount option and it seems problematic to me. In any case, not in this commit.)
Also see a post I just made in tech-kern about the flag conflicts.

branches: 1.64.2; Stick ffs_ in front of the following macros: fragstoblks() blkstofrags() fragnum() blknum()
to finish the job of distinguishing them from the lfs versions, which Christos renamed the other day.
I believe this is the last of the overtly ambiguous exported symbols from ffs... or at least, the last of the ones that conflicted with lfs. ffs still pollutes the C namespace very broadly (as does ufs) and this needs quite a bit more cleanup.
XXX: boo on macros with lowercase names. But I'm not tackling that just yet.

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.

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.

Usage is checked by fsck_ffs (no more quotacheck) and is covered by the WAPBL journal. Enabled with kernel option QUOTA2 (added where QUOTA was enabled in kernel config files), turned on with tunefs(8) on a per-filesystem basis. mount_mfs(8) can also turn quotas on.

Bring over fixes from FreeBSD that weren't incorporated yet, mainly from Kirk McKusick. They implement taking pending block/inode frees into account for the sake of correct statfs() numbers, and adding a new softdep type (newdirblk) to correctly handle newly allocated directory blocks.
Minor additional changes: 1) swap the newly introduced fs_pendinginodes and fs_pendingblock fields in ffs_sb_swap, and 2) declare lkt_held in the debug version of the softdep lock structure volatile, as it can be modified from interrupt context #ifdef DEBUG.

branches: 1.20.2; Incorporate the enhanced ffs_dirpref() by Grigoriy Orlov, as found in FreeBSD (three commits; the initial work, man page updates, and a fix to ffs_reload()), with the following differences: - Be consistent between newfs(8) and tunefs(8) as to the options which set and control the tuning parameters for this work (avgfilesize & avgfpdir) - Use u_int16_t instead of u_int8_t to keep track of the number of contiguous directories (suggested by Chuck Silvers) - Work within our FFS_EI framework - Ensure that fs->fs_maxclusters and fs->fs_contigdirs don't point to the same area of memory
The new algorithm has a marked performance increase, especially when performing tasks such as untarring pkgsrc.tar.gz, etc.
The original FreeBSD commit messages are attached:
===== mckusick 2001/04/10 01:39:00 PDT Directory layout preference improvements from Grigoriy Orlov <gluk@ptci.ru>. His description of the problem and solution follow. My own tests show speedups on typical filesystem intensive workloads of 5% to 12% which is very impressive considering the small amount of code change involved.
------
One day I noticed that some file operations run much faster on small file systems then on big ones. I've looked at the ffs algorithms, thought about them, and redesigned the dirpref algorithm.
First I want to describe the results of my tests. These results are old and I have improved the algorithm after these tests were done. Nevertheless they show how big the perfomance speedup may be. I have done two file/directory intensive tests on a two OpenBSD systems with old and new dirpref algorithm. The first test is "tar -xzf ports.tar.gz", the second is "rm -rf ports". The ports.tar.gz file is the ports collection from the OpenBSD 2.8 release. It contains 6596 directories and 13868 files. The test systems are:
1. Celeron-450, 128Mb, two IDE drives, the system at wd0, file system for test is at wd1. Size of test file system is 8 Gb, number of cg=991, size of cg is 8m, block size = 8k, fragment size = 1k OpenBSD-current from Dec 2000 with BUFCACHEPERCENT=35
2. PIII-600, 128Mb, two IBM DTLA-307045 IDE drives at i815e, the system at wd0, file system for test is at wd1. Size of test file system is 40 Gb, number of cg=5324, size of cg is 8m, block size = 8k, fragment size = 1k OpenBSD-current from Dec 2000 with BUFCACHEPERCENT=50

Algorithm description
The old dirpref algorithm is described in comments:
/* * Find a cylinder to place a directory. * * The policy implemented by this algorithm is to select from * among those cylinder groups with above the average number of * free inodes, the one with the smallest number of directories. */
A new directory is allocated in a different cylinder groups than its parent directory resulting in a directory tree that is spreaded across all the cylinder groups. This spreading out results in a non-optimal access to the directories and files. When we have a small filesystem it is not a problem but when the filesystem is big then perfomance degradation becomes very apparent.
What I mean by a big file system ?
1. A big filesystem is a filesystem which occupy 20-30 or more percent of total drive space, i.e. first and last cylinder are physically located relatively far from each other. 2. It has a relatively large number of cylinder groups, for example more cylinder groups than 50% of the buffers in the buffer cache.
The first results in long access times, while the second results in many buffers being used by metadata operations. Such operations use cylinder group blocks and on-disk inode blocks. The cylinder group block (fs->fs_cblkno) contains struct cg, inode and block bit maps. It is 2k in size for the default filesystem parameters. If new and parent directories are located in different cylinder groups then the system performs more input/output operations and uses more buffers. On filesystems with many cylinder groups, lots of cache buffers are used for metadata operations.
My solution for this problem is very simple. I allocate many directories in one cylinder group. I also do some things, so that the new allocation method does not cause excessive fragmentation and all directory inodes will not be located at a location far from its file's inodes and data. The algorithm is: /* * Find a cylinder group to place a directory. * * The policy implemented by this algorithm is to allocate a * directory inode in the same cylinder group as its parent * directory, but also to reserve space for its files inodes * and data. Restrict the number of directories which may be * allocated one after another in the same cylinder group * without intervening allocation of files. * * If we allocate a first level directory then force allocation * in another cylinder group. */
My early versions of dirpref give me a good results for a wide range of file operations and different filesystem capacities except one case: those applications that create their entire directory structure first and only later fill this structure with files.
My solution for such and similar cases is to limit a number of directories which may be created one after another in the same cylinder group without intervening file creations. For this purpose, I allocate an array of counters at mount time. This array is linked to the superblock fs->fs_contigdirs[cg]. Each time a directory is created the counter increases and each time a file is created the counter decreases. A 60Gb filesystem with 8mb/cg requires 10kb of memory for the counters array.
The maxcontigdirs is a maximum number of directories which may be created without an intervening file creation. I found in my tests that the best performance occurs when I restrict the number of directories in one cylinder group such that all its files may be located in the same cylinder group. There may be some deterioration in performance if all the file inodes are in the same cylinder group as its containing directory, but their data partially resides in a different cylinder group. The maxcontigdirs value is calculated to try to prevent this condition. Since there is no way to know how many files and directories will be allocated later I added two optimization parameters in superblock/tunefs. They are:
int32_t fs_avgfilesize; /* expected average file size */ int32_t fs_avgfpdir; /* expected # of files per directory */
These parameters have reasonable defaults but may be tweeked for special uses of a filesystem. They are only necessary in rare cases like better tuning a filesystem being used to store a squid cache.
I have been using this algorithm for about 3 months. I have done a lot of testing on filesystems with different capacities, average filesize, average number of files per directory, and so on. I think this algorithm has no negative impact on filesystem perfomance. It works better than the default one in all cases. The new dirpref will greatly improve untarring/removing/coping of big directories, decrease load on cvs servers and much more. The new dirpref doesn't speedup a compilation process, but also doesn't slow it down.
Obtained from: Grigoriy Orlov <gluk@ptci.ru> =====
===== iedowse 2001/04/23 17:37:17 PDT Pre-dirpref versions of fsck may zero out the new superblock fields fs_contigdirs, fs_avgfilesize and fs_avgfpdir. This could cause panics if these fields were zeroed while a filesystem was mounted read-only, and then remounted read-write.
Add code to ffs_reload() which copies the fs_contigdirs pointer from the previous superblock, and reinitialises fs_avgf* if necessary.

deprecate fs_fscktime; we never used it.
in an effort to maintain compatibility with freebsd/openbsd/whatever, i'm attempting to get the superblock format in sync, and freebsd uses the int32_t at this position for `fs_pendinginodes'.
if we ever decide to implement fscktime functionality, we'll: a) make sure to liaise with the other projects to reserve the same spare field b) actually implement the code this time ...
(this is also preparing us for other changes, like the new dirpref code)

Incorporate fix by iedowse @ FreeBSD to allow disks with large numbers of cylinder groups to work correctly, with minor modifications by me to work with our FFS_EI code. From the FreeBSD commit message:
The ffs superblock includes a 128-byte region for use by temporary in-core pointers to summary information. An array in this region (fs_csp) could overflow on filesystems with a very large number of cylinder groups (~16000 on i386 with 8k blocks). When this happens, other fields in the superblock get corrupted, and fsck refuses to check the filesystem.
Solve this problem by replacing the fs_csp array in 'struct fs' with a single pointer, and add padding to keep the length of the 128-byte region fixed. Update the kernel and userland utilities to use just this single pointer.
With this change, the kernel no longer makes use of the superblock fields 'fs_csshift' and 'fs_csmask'. Add a comment to newfs/mkfs.c to indicate that these fields must be calculated for compatibility with older kernels.

More fixes from FreeBSD (with changes): - Cast blk argument to lblktosize() to (off_t), to prevent 32 bit overflow. whilst almost every use in ffs used this for small blknos, there are potential issues, and it's safer this way. (as discussed with chuq) - Use 64bit (off_t) math to calculate if we have hit our freespace() limit. Necessary for coherent results on filesystems bigger than 0.5Tb. - Use lblktosize() in blksize() and dblksize(), to make it obvious what's happening - Remove sblksize() - nothing uses it

Add support for reading/writing FFS in non-native byte order, conditioned to "options FFS_EI". The superblock and inodes (without blk addr) are byteswapped at disk read/write time, other metadatas are byteswapped when used (as they are acceeded directly in the buffer cache). This required the addition of a "um_flags" field to struct ufsmount. ffs_bswap.c contains superblock and inode byteswap routines also used by userland utilities.

Add support for ext2fs, this needed a few modifications to ufs/ufs/inode.h: - added an "union inode_ext" to struct inode, for the per-fs extentions. For now only ext2fs uses it. - i_din is now an union: union { struct dinode ffs_din; /* 128 bytes of the on-disk dinode. */ struct ext2fs_dinode e2fs_din; /* 128 bytes of the on-disk dinode. */ } i_din Added a lot of #define i_ffs_* and i_e2fs_* to access the fields. - Added two macros: FFS_ITIMES and EXT2FS_ITIMES. ITIMES calls the rigth macro, depending on the time of the inode. ITIMES is used where necessary, FFS_ITIMES and EXT2FS_ITIMES in other places.

This conflicts with our flag for FS_INDEXDIRS. Apparently FreeBSD changed that arbitrarily on their end when implementing journaled softupdates, so follow their lead.
Unfortunately, the new value they use for FS_INDEXDIRS conflicts with our flag FS_DOQUOTA2 for 64-bit quotas. Since the only thing in our tree that knows about FS_INDEXDIRS is dumpfs (for printing it), leave FS_INDEXDIRS commented out.
Also add FS_NFS4ACLS from FreeBSD, commented out because it conflicts with our FS_DOWAPBL, and FS_TRIM.
(We could honor FS_TRIM as we have code for doing that; however I'm not sure why FreeBSD chose to make it an on-disk flag instead of e.g. a mount option and it seems problematic to me. In any case, not in this commit.)
Also see a post I just made in tech-kern about the flag conflicts.

Unlike other filesystems this has some side issues because the shift values are stored in the superblock and because userland utitlies share the same fsbtodb macros.
-> the kernel now ignores the value stored in the superblock. -> the macro adaption is only done for defined(_KERNEL) code.

Bring over fixes from FreeBSD that weren't incorporated yet, mainly from Kirk McKusick. They implement taking pending block/inode frees into account for the sake of correct statfs() numbers, and adding a new softdep type (newdirblk) to correctly handle newly allocated directory blocks.
Minor additional changes: 1) swap the newly introduced fs_pendinginodes and fs_pendingblock fields in ffs_sb_swap, and 2) declare lkt_held in the debug version of the softdep lock structure volatile, as it can be modified from interrupt context #ifdef DEBUG.

===== mckusick 2001/04/10 01:39:00 PDT Directory layout preference improvements from Grigoriy Orlov <gluk@ptci.ru>. His description of the problem and solution follow. My own tests show speedups on typical filesystem intensive workloads of 5% to 12% which is very impressive considering the small amount of code change involved.
------
One day I noticed that some file operations run much faster on small file systems then on big ones. I've looked at the ffs algorithms, thought about them, and redesigned the dirpref algorithm.
First I want to describe the results of my tests. These results are old and I have improved the algorithm after these tests were done. Nevertheless they show how big the perfomance speedup may be. I have done two file/directory intensive tests on a two OpenBSD systems with old and new dirpref algorithm. The first test is "tar -xzf ports.tar.gz", the second is "rm -rf ports". The ports.tar.gz file is the ports collection from the OpenBSD 2.8 release. It contains 6596 directories and 13868 files. The test systems are:
1. Celeron-450, 128Mb, two IDE drives, the system at wd0, file system for test is at wd1. Size of test file system is 8 Gb, number of cg=991, size of cg is 8m, block size = 8k, fragment size = 1k OpenBSD-current from Dec 2000 with BUFCACHEPERCENT=35
2. PIII-600, 128Mb, two IBM DTLA-307045 IDE drives at i815e, the system at wd0, file system for test is at wd1. Size of test file system is 40 Gb, number of cg=5324, size of cg is 8m, block size = 8k, fragment size = 1k OpenBSD-current from Dec 2000 with BUFCACHEPERCENT=50
You can get more info about the test systems and methods at: http://www.ptci.ru/gluk/dirpref/old/dirpref.html

Algorithm description
The old dirpref algorithm is described in comments:
/* * Find a cylinder to place a directory. * * The policy implemented by this algorithm is to select from * among those cylinder groups with above the average number of * free inodes, the one with the smallest number of directories. */
A new directory is allocated in a different cylinder groups than its parent directory resulting in a directory tree that is spreaded across all the cylinder groups. This spreading out results in a non-optimal access to the directories and files. When we have a small filesystem it is not a problem but when the filesystem is big then perfomance degradation becomes very apparent.
What I mean by a big file system ?
1. A big filesystem is a filesystem which occupy 20-30 or more percent of total drive space, i.e. first and last cylinder are physically located relatively far from each other. 2. It has a relatively large number of cylinder groups, for example more cylinder groups than 50% of the buffers in the buffer cache.
The first results in long access times, while the second results in many buffers being used by metadata operations. Such operations use cylinder group blocks and on-disk inode blocks. The cylinder group block (fs->fs_cblkno) contains struct cg, inode and block bit maps. It is 2k in size for the default filesystem parameters. If new and parent directories are located in different cylinder groups then the system performs more input/output operations and uses more buffers. On filesystems with many cylinder groups, lots of cache buffers are used for metadata operations.
My solution for this problem is very simple. I allocate many directories in one cylinder group. I also do some things, so that the new allocation method does not cause excessive fragmentation and all directory inodes will not be located at a location far from its file's inodes and data. The algorithm is: /* * Find a cylinder group to place a directory. * * The policy implemented by this algorithm is to allocate a * directory inode in the same cylinder group as its parent * directory, but also to reserve space for its files inodes * and data. Restrict the number of directories which may be * allocated one after another in the same cylinder group * without intervening allocation of files. * * If we allocate a first level directory then force allocation * in another cylinder group. */
My early versions of dirpref give me a good results for a wide range of file operations and different filesystem capacities except one case: those applications that create their entire directory structure first and only later fill this structure with files.
My solution for such and similar cases is to limit a number of directories which may be created one after another in the same cylinder group without intervening file creations. For this purpose, I allocate an array of counters at mount time. This array is linked to the superblock fs->fs_contigdirs[cg]. Each time a directory is created the counter increases and each time a file is created the counter decreases. A 60Gb filesystem with 8mb/cg requires 10kb of memory for the counters array.
The maxcontigdirs is a maximum number of directories which may be created without an intervening file creation. I found in my tests that the best performance occurs when I restrict the number of directories in one cylinder group such that all its files may be located in the same cylinder group. There may be some deterioration in performance if all the file inodes are in the same cylinder group as its containing directory, but their data partially resides in a different cylinder group. The maxcontigdirs value is calculated to try to prevent this condition. Since there is no way to know how many files and directories will be allocated later I added two optimization parameters in superblock/tunefs. They are:
int32_t fs_avgfilesize; /* expected average file size */ int32_t fs_avgfpdir; /* expected # of files per directory */
These parameters have reasonable defaults but may be tweeked for special uses of a filesystem. They are only necessary in rare cases like better tuning a filesystem being used to store a squid cache.
I have been using this algorithm for about 3 months. I have done a lot of testing on filesystems with different capacities, average filesize, average number of files per directory, and so on. I think this algorithm has no negative impact on filesystem perfomance. It works better than the default one in all cases. The new dirpref will greatly improve untarring/removing/coping of big directories, decrease load on cvs servers and much more. The new dirpref doesn't speedup a compilation process, but also doesn't slow it down.

===== iedowse 2001/04/23 17:37:17 PDT Pre-dirpref versions of fsck may zero out the new superblock fields fs_contigdirs, fs_avgfilesize and fs_avgfpdir. This could cause panics if these fields were zeroed while a filesystem was mounted read-only, and then remounted read-write.
Add code to ffs_reload() which copies the fs_contigdirs pointer from the previous superblock, and reinitialises fs_avgf* if necessary.

deprecate fs_fscktime; we never used it.
in an effort to maintain compatibility with freebsd/openbsd/whatever, i'm attempting to get the superblock format in sync, and freebsd uses the int32_t at this position for `fs_pendinginodes'.
if we ever decide to implement fscktime functionality, we'll: a) make sure to liaise with the other projects to reserve the same spare field b) actually implement the code this time ...
(this is also preparing us for other changes, like the new dirpref code)

Incorporate fix by iedowse @ FreeBSD to allow disks with large numbers of cylinder groups to work correctly, with minor modifications by me to work with our FFS_EI code. From the FreeBSD commit message:
The ffs superblock includes a 128-byte region for use by temporary in-core pointers to summary information. An array in this region (fs_csp) could overflow on filesystems with a very large number of cylinder groups (~16000 on i386 with 8k blocks). When this happens, other fields in the superblock get corrupted, and fsck refuses to check the filesystem.
Solve this problem by replacing the fs_csp array in 'struct fs' with a single pointer, and add padding to keep the length of the 128-byte region fixed. Update the kernel and userland utilities to use just this single pointer.
With this change, the kernel no longer makes use of the superblock fields 'fs_csshift' and 'fs_csmask'. Add a comment to newfs/mkfs.c to indicate that these fields must be calculated for compatibility with older kernels.

More fixes from FreeBSD (with changes): - Cast blk argument to lblktosize() to (off_t), to prevent 32 bit overflow. whilst almost every use in ffs used this for small blknos, there are potential issues, and it's safer this way. (as discussed with chuq) - Use 64bit (off_t) math to calculate if we have hit our freespace() limit. Necessary for coherent results on filesystems bigger than 0.5Tb. - Use lblktosize() in blksize() and dblksize(), to make it obvious what's happening - Remove sblksize() - nothing uses it

some improvements from freebsd/openbsd - replace the unused fs_headswitch and fs_trkseek with fs_id[2], bringing our struct fs closer to that in freebsd & openbsd (& solaris FWIW) - dumpfs: improve warning message when cpc == 0

Add support for reading/writing FFS in non-native byte order, conditioned to "options FFS_EI". The superblock and inodes (without blk addr) are byteswapped at disk read/write time, other metadatas are byteswapped when used (as they are acceeded directly in the buffer cache). This required the addition of a "um_flags" field to struct ufsmount. ffs_bswap.c contains superblock and inode byteswap routines also used by userland utilities.

Add support for ext2fs, this needed a few modifications to ufs/ufs/inode.h: - added an "union inode_ext" to struct inode, for the per-fs extentions. For now only ext2fs uses it. - i_din is now an union: union { struct dinode ffs_din; /* 128 bytes of the on-disk dinode. */ struct ext2fs_dinode e2fs_din; /* 128 bytes of the on-disk dinode. */ } i_din Added a lot of #define i_ffs_* and i_e2fs_* to access the fields. - Added two macros: FFS_ITIMES and EXT2FS_ITIMES. ITIMES calls the rigth macro, depending on the time of the inode. ITIMES is used where necessary, FFS_ITIMES and EXT2FS_ITIMES in other places.

Make use of the `fs_clean' field. If it was set when the file system was mounted or upgraded to r-w, then clear it and set it again later when the file system is unmounted or downgraded.
