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).

Round of uvm.h cleanup.
The poorly named uvm.h is generally supposed to be for uvm-internal users only.
- Narrow it to files that actually need it -- mostly files that need to query whether curlwp is the pagedaemon, which should maybe be exposed by an external header.
- Use uvm_extern.h where feasible and uvm_*.h for things not exposed by it. We should split up uvm_extern.h but this will serve for now to reduce the uvm.h dependencies.
- Use uvm_stat.h and #ifdef UVMHIST uvm.h for files that use UVMHIST(ubchist), since ubchist is declared in uvm.h but the reference evaporates if UVMHIST is not defined, so we reduce header file dependencies.
- Make uvm_device.h and uvm_swap.h independently includable while here.

branches: 1.63.4; 1.63.14; Update the kernhist(9) kernel history code to address issues identified in PR kern/52639, as well as some general cleaning-up...
(As proposed on tech-kern@ with additional changes and enhancements.)
Details of changes:
* All history arguments are now stored as uintmax_t values[1], both in the kernel and in the structures used for exporting the history data to userland via sysctl(9). This avoids problems on some architectures where passing a 64-bit (or larger) value to printf(3) can cause it to process the value as multiple arguments. (This can be particularly problematic when printf()'s format string is not a literal, since in that case the compiler cannot know how large each argument should be.)
* Update the data structures used for exporting kernel history data to include a version number as well as the length of history arguments.
* All [2] existing users of kernhist(9) have had their format strings updated. Each format specifier now includes an explicit length modifier 'j' to refer to numeric values of the size of uintmax_t.
* All [2] existing users of kernhist(9) have had their format strings updated to replace uses of "%p" with "%#jx", and the pointer arguments are now cast to (uintptr_t) before being subsequently cast to (uintmax_t). This is needed to avoid compiler warnings about casting "pointer to integer of a different size."
* All [2] existing users of kernhist(9) have had instances of "%s" or "%c" format strings replaced with numeric formats; several instances of mis-match between format string and argument list have been fixed.
* vmstat(1) has been modified to handle the new size of arguments in the history data as exported by sysctl(9).
* vmstat(1) now provides a warning message if the history requested with the -u option does not exist (previously, this condition was silently ignored, with only a single blank line being printed).
* vmstat(1) now checks the version and argument length included in the data exported via sysctl(9) and exits if they do not match the values with which vmstat was built.
* The kernhist(9) man-page has been updated to note the additional requirements imposed on the format strings, along with several other minor changes and enhancements.
[1] It would have been possible to use an explicit length (for example, uint64_t) for the history arguments. But that would require another "rototill" of all the users in the future when we add support for an architecture that supports a larger size. Also, the printf(3) format specifiers for explicitly-sized values, such as "%"PRIu64, are much more verbose (and less aesthetically appealing, IMHO) than simply using "%ju".
[2] I've tried very hard to find "all [the] existing users of kernhist(9)" but it is possible that I've missed some of them. I would be glad to update any stragglers that anyone identifies.

Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have the same values in ext2fs and ffs.
No functional change intended.

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.

Make sure all cached buffers with valid, not yet written data have been run through copy-on-write. Call fscow_run() with valid data where possible.
The LP_UFSCOW hack is no longer needed to protect ffs_copyonwrite() against endless recursion.
- Add a flag B_MODIFY to bread(), breada() and breadn(). If set the caller intends to modify the buffer returned.
- Always run copy-on-write on buffers returned from ffs_balloc().
- Add new function ffs_getblk() that gets a buffer, assigns a new blkno, may clear the buffer and runs copy-on-write. Process possible errors from getblk() or fscow_run(). Part of PR kern/38664.

Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD.
- Not enabled by default. Needs kernel option FFS_SNAPSHOT. - Change parameters of ffs_blkfree. - Let the copy-on-write functions return an error so spec_strategy may fail if the copy-on-write fails. - Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock. - Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer. - Add a function ffs_checkfreefile needed for snapshot creation. - Add special handling of snapshot files: Snapshots may not be opened for writing and the attributes are read-only. Use the mtime as the time this snapshot was taken. Deny mtime updates for snapshot files. - Add function transferlockers to transfer any waiting processes from one lock to another. - Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through a vnode. - Add snapshot support to ls, fsck_ffs and dump.
Welcome to 2.0F.

branches: 1.33.2; 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.

branches: 1.29.8; 1.29.10; the previous fix (in rev. 1.26) for hangs when the filesystem is full was wrong, so fix it right this time. undo the previous change and instead, replace the troublesome VOP_FSYNC()s with code that just flushes the particular indirect blocks that we allocated. this resolves the softdeps for those blocks. then we can change the pointer for the first indirect block we allocated to zero, write that, and finally invalidate all the indirect blocks we've touched. also, wait until after we finish all this before freeing any blocks we allocated. fixes PRs 14413 and 14423.

a whole bunch of changes to improve performance and robustness under load:
- remove special treatment of pager_map mappings in pmaps. this is required now, since I've removed the globals that expose the address range. pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's no longer any need to special-case it. - eliminate struct uvm_vnode by moving its fields into struct vnode. - rewrite the pageout path. the pager is now responsible for handling the high-level requests instead of only getting control after a bunch of work has already been done on its behalf. this will allow us to UBCify LFS, which needs tighter control over its pages than other filesystems do. writing a page to disk no longer requires making it read-only, which allows us to write wired pages without causing all kinds of havoc. - use a new PG_PAGEOUT flag to indicate that a page should be freed on behalf of the pagedaemon when it's unlocked. this flag is very similar to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the pageout fails due to eg. an indirect-block buffer being locked. this allows us to remove the "version" field from struct vm_page, and together with shrinking "loan_count" from 32 bits to 16, struct vm_page is now 4 bytes smaller. - no longer use PG_RELEASED for swap-backed pages. if the page is busy because it's being paged out, we can't release the swap slot to be reallocated until that write is complete, but unlike with vnodes we don't keep a count of in-progress writes so there's no good way to know when the write is done. instead, when we need to free a busy swap-backed page, just sleep until we can get it busy ourselves. - implement a fast-path for extending writes which allows us to avoid zeroing new pages. this substantially reduces cpu usage. - encapsulate the data used by the genfs code in a struct genfs_node, which must be the first element of the filesystem-specific vnode data for filesystems which use genfs_{get,put}pages(). - eliminate many of the UVM pagerops, since they aren't needed anymore now that the pager "put" operation is a higher-level operation. - enhance the genfs code to allow NFS to use the genfs_{get,put}pages instead of a modified copy. - clean up struct vnode by removing all the fields that used to be used by the vfs_cluster.c code (which we don't use anymore with UBC). - remove kmem_object and mb_object since they were useless. instead of allocating pages to these objects, we now just allocate pages with no object. such pages are mapped in the kernel until they are freed, so we can use the mapping to find the page to free it. this allows us to remove splvm() protection in several places.
The sum of all these changes improves write throughput on my decstation 5000/200 to within 1% of the rate of NetBSD 1.5 and reduces the elapsed time for "make release" of a NetBSD 1.5 source tree on my 128MB pc to 10% less than a 1.5 kernel took.

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.

Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many architectures), truncate them intelligently instead. The truncation is done centralized in vnode_pager.c. This prevents from wrap-over effects when parts of large (>2^32 byte) files are mmapped. Don't allow to mmap above the numerical range of vm_offset_t. This is considered a temporary solution until the vm system handles the object sizes/offsets more cleanly.

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.

Round of uvm.h cleanup.
The poorly named uvm.h is generally supposed to be for uvm-internal users only.
- Narrow it to files that actually need it -- mostly files that need to query whether curlwp is the pagedaemon, which should maybe be exposed by an external header.
- Use uvm_extern.h where feasible and uvm_*.h for things not exposed by it. We should split up uvm_extern.h but this will serve for now to reduce the uvm.h dependencies.
- Use uvm_stat.h and #ifdef UVMHIST uvm.h for files that use UVMHIST(ubchist), since ubchist is declared in uvm.h but the reference evaporates if UVMHIST is not defined, so we reduce header file dependencies.
- Make uvm_device.h and uvm_swap.h independently includable while here.

branches: 1.63.4; 1.63.14; Update the kernhist(9) kernel history code to address issues identified in PR kern/52639, as well as some general cleaning-up...
(As proposed on tech-kern@ with additional changes and enhancements.)
Details of changes:
* All history arguments are now stored as uintmax_t values[1], both in the kernel and in the structures used for exporting the history data to userland via sysctl(9). This avoids problems on some architectures where passing a 64-bit (or larger) value to printf(3) can cause it to process the value as multiple arguments. (This can be particularly problematic when printf()'s format string is not a literal, since in that case the compiler cannot know how large each argument should be.)
* Update the data structures used for exporting kernel history data to include a version number as well as the length of history arguments.
* All [2] existing users of kernhist(9) have had their format strings updated. Each format specifier now includes an explicit length modifier 'j' to refer to numeric values of the size of uintmax_t.
* All [2] existing users of kernhist(9) have had their format strings updated to replace uses of "%p" with "%#jx", and the pointer arguments are now cast to (uintptr_t) before being subsequently cast to (uintmax_t). This is needed to avoid compiler warnings about casting "pointer to integer of a different size."
* All [2] existing users of kernhist(9) have had instances of "%s" or "%c" format strings replaced with numeric formats; several instances of mis-match between format string and argument list have been fixed.
* vmstat(1) has been modified to handle the new size of arguments in the history data as exported by sysctl(9).
* vmstat(1) now provides a warning message if the history requested with the -u option does not exist (previously, this condition was silently ignored, with only a single blank line being printed).
* vmstat(1) now checks the version and argument length included in the data exported via sysctl(9) and exits if they do not match the values with which vmstat was built.
* The kernhist(9) man-page has been updated to note the additional requirements imposed on the format strings, along with several other minor changes and enhancements.
[1] It would have been possible to use an explicit length (for example, uint64_t) for the history arguments. But that would require another "rototill" of all the users in the future when we add support for an architecture that supports a larger size. Also, the printf(3) format specifiers for explicitly-sized values, such as "%"PRIu64, are much more verbose (and less aesthetically appealing, IMHO) than simply using "%ju".
[2] I've tried very hard to find "all [the] existing users of kernhist(9)" but it is possible that I've missed some of them. I would be glad to update any stragglers that anyone identifies.

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.

Make sure all cached buffers with valid, not yet written data have been run through copy-on-write. Call fscow_run() with valid data where possible.
The LP_UFSCOW hack is no longer needed to protect ffs_copyonwrite() against endless recursion.
- Add a flag B_MODIFY to bread(), breada() and breadn(). If set the caller intends to modify the buffer returned.
- Always run copy-on-write on buffers returned from ffs_balloc().
- Add new function ffs_getblk() that gets a buffer, assigns a new blkno, may clear the buffer and runs copy-on-write. Process possible errors from getblk() or fscow_run(). Part of PR kern/38664.

Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD.
- Not enabled by default. Needs kernel option FFS_SNAPSHOT. - Change parameters of ffs_blkfree. - Let the copy-on-write functions return an error so spec_strategy may fail if the copy-on-write fails. - Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock. - Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer. - Add a function ffs_checkfreefile needed for snapshot creation. - Add special handling of snapshot files: Snapshots may not be opened for writing and the attributes are read-only. Use the mtime as the time this snapshot was taken. Deny mtime updates for snapshot files. - Add function transferlockers to transfer any waiting processes from one lock to another. - Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through a vnode. - Add snapshot support to ls, fsck_ffs and dump.

a whole bunch of changes to improve performance and robustness under load:
- remove special treatment of pager_map mappings in pmaps. this is required now, since I've removed the globals that expose the address range. pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's no longer any need to special-case it. - eliminate struct uvm_vnode by moving its fields into struct vnode. - rewrite the pageout path. the pager is now responsible for handling the high-level requests instead of only getting control after a bunch of work has already been done on its behalf. this will allow us to UBCify LFS, which needs tighter control over its pages than other filesystems do. writing a page to disk no longer requires making it read-only, which allows us to write wired pages without causing all kinds of havoc. - use a new PG_PAGEOUT flag to indicate that a page should be freed on behalf of the pagedaemon when it's unlocked. this flag is very similar to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the pageout fails due to eg. an indirect-block buffer being locked. this allows us to remove the "version" field from struct vm_page, and together with shrinking "loan_count" from 32 bits to 16, struct vm_page is now 4 bytes smaller. - no longer use PG_RELEASED for swap-backed pages. if the page is busy because it's being paged out, we can't release the swap slot to be reallocated until that write is complete, but unlike with vnodes we don't keep a count of in-progress writes so there's no good way to know when the write is done. instead, when we need to free a busy swap-backed page, just sleep until we can get it busy ourselves. - implement a fast-path for extending writes which allows us to avoid zeroing new pages. this substantially reduces cpu usage. - encapsulate the data used by the genfs code in a struct genfs_node, which must be the first element of the filesystem-specific vnode data for filesystems which use genfs_{get,put}pages(). - eliminate many of the UVM pagerops, since they aren't needed anymore now that the pager "put" operation is a higher-level operation. - enhance the genfs code to allow NFS to use the genfs_{get,put}pages instead of a modified copy. - clean up struct vnode by removing all the fields that used to be used by the vfs_cluster.c code (which we don't use anymore with UBC). - remove kmem_object and mb_object since they were useless. instead of allocating pages to these objects, we now just allocate pages with no object. such pages are mapped in the kernel until they are freed, so we can use the mapping to find the page to free it. this allows us to remove splvm() protection in several places.
The sum of all these changes improves write throughput on my decstation 5000/200 to within 1% of the rate of NetBSD 1.5 and reduces the elapsed time for "make release" of a NetBSD 1.5 source tree on my 128MB pc to 10% less than a 1.5 kernel took.

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.

Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many architectures), truncate them intelligently instead. The truncation is done centralized in vnode_pager.c. This prevents from wrap-over effects when parts of large (>2^32 byte) files are mmapped. Don't allow to mmap above the numerical range of vm_offset_t. This is considered a temporary solution until the vm system handles the object sizes/offsets more cleanly.

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.

Update the kernhist(9) kernel history code to address issues identified in PR kern/52639, as well as some general cleaning-up...
(As proposed on tech-kern@ with additional changes and enhancements.)
Details of changes:
* All history arguments are now stored as uintmax_t values[1], both in the kernel and in the structures used for exporting the history data to userland via sysctl(9). This avoids problems on some architectures where passing a 64-bit (or larger) value to printf(3) can cause it to process the value as multiple arguments. (This can be particularly problematic when printf()'s format string is not a literal, since in that case the compiler cannot know how large each argument should be.)
* Update the data structures used for exporting kernel history data to include a version number as well as the length of history arguments.
* All [2] existing users of kernhist(9) have had their format strings updated. Each format specifier now includes an explicit length modifier 'j' to refer to numeric values of the size of uintmax_t.
* All [2] existing users of kernhist(9) have had their format strings updated to replace uses of "%p" with "%#jx", and the pointer arguments are now cast to (uintptr_t) before being subsequently cast to (uintmax_t). This is needed to avoid compiler warnings about casting "pointer to integer of a different size."
* All [2] existing users of kernhist(9) have had instances of "%s" or "%c" format strings replaced with numeric formats; several instances of mis-match between format string and argument list have been fixed.
* vmstat(1) has been modified to handle the new size of arguments in the history data as exported by sysctl(9).
* vmstat(1) now provides a warning message if the history requested with the -u option does not exist (previously, this condition was silently ignored, with only a single blank line being printed).
* vmstat(1) now checks the version and argument length included in the data exported via sysctl(9) and exits if they do not match the values with which vmstat was built.
* The kernhist(9) man-page has been updated to note the additional requirements imposed on the format strings, along with several other minor changes and enhancements.
[1] It would have been possible to use an explicit length (for example, uint64_t) for the history arguments. But that would require another "rototill" of all the users in the future when we add support for an architecture that supports a larger size. Also, the printf(3) format specifiers for explicitly-sized values, such as "%"PRIu64, are much more verbose (and less aesthetically appealing, IMHO) than simply using "%ju".
[2] I've tried very hard to find "all [the] existing users of kernhist(9)" but it is possible that I've missed some of them. I would be glad to update any stragglers that anyone identifies.

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.

Make sure all cached buffers with valid, not yet written data have been run through copy-on-write. Call fscow_run() with valid data where possible.
The LP_UFSCOW hack is no longer needed to protect ffs_copyonwrite() against endless recursion.
- Add a flag B_MODIFY to bread(), breada() and breadn(). If set the caller intends to modify the buffer returned.
- Always run copy-on-write on buffers returned from ffs_balloc().
- Add new function ffs_getblk() that gets a buffer, assigns a new blkno, may clear the buffer and runs copy-on-write. Process possible errors from getblk() or fscow_run(). Part of PR kern/38664.

Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD.
- Not enabled by default. Needs kernel option FFS_SNAPSHOT. - Change parameters of ffs_blkfree. - Let the copy-on-write functions return an error so spec_strategy may fail if the copy-on-write fails. - Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock. - Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer. - Add a function ffs_checkfreefile needed for snapshot creation. - Add special handling of snapshot files: Snapshots may not be opened for writing and the attributes are read-only. Use the mtime as the time this snapshot was taken. Deny mtime updates for snapshot files. - Add function transferlockers to transfer any waiting processes from one lock to another. - Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through a vnode. - Add snapshot support to ls, fsck_ffs and dump.
Welcome to 2.0F.

branches: 1.29.8; 1.29.10; the previous fix (in rev. 1.26) for hangs when the filesystem is full was wrong, so fix it right this time. undo the previous change and instead, replace the troublesome VOP_FSYNC()s with code that just flushes the particular indirect blocks that we allocated. this resolves the softdeps for those blocks. then we can change the pointer for the first indirect block we allocated to zero, write that, and finally invalidate all the indirect blocks we've touched. also, wait until after we finish all this before freeing any blocks we allocated. fixes PRs 14413 and 14423.

a whole bunch of changes to improve performance and robustness under load:
- remove special treatment of pager_map mappings in pmaps. this is required now, since I've removed the globals that expose the address range. pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's no longer any need to special-case it. - eliminate struct uvm_vnode by moving its fields into struct vnode. - rewrite the pageout path. the pager is now responsible for handling the high-level requests instead of only getting control after a bunch of work has already been done on its behalf. this will allow us to UBCify LFS, which needs tighter control over its pages than other filesystems do. writing a page to disk no longer requires making it read-only, which allows us to write wired pages without causing all kinds of havoc. - use a new PG_PAGEOUT flag to indicate that a page should be freed on behalf of the pagedaemon when it's unlocked. this flag is very similar to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the pageout fails due to eg. an indirect-block buffer being locked. this allows us to remove the "version" field from struct vm_page, and together with shrinking "loan_count" from 32 bits to 16, struct vm_page is now 4 bytes smaller. - no longer use PG_RELEASED for swap-backed pages. if the page is busy because it's being paged out, we can't release the swap slot to be reallocated until that write is complete, but unlike with vnodes we don't keep a count of in-progress writes so there's no good way to know when the write is done. instead, when we need to free a busy swap-backed page, just sleep until we can get it busy ourselves. - implement a fast-path for extending writes which allows us to avoid zeroing new pages. this substantially reduces cpu usage. - encapsulate the data used by the genfs code in a struct genfs_node, which must be the first element of the filesystem-specific vnode data for filesystems which use genfs_{get,put}pages(). - eliminate many of the UVM pagerops, since they aren't needed anymore now that the pager "put" operation is a higher-level operation. - enhance the genfs code to allow NFS to use the genfs_{get,put}pages instead of a modified copy. - clean up struct vnode by removing all the fields that used to be used by the vfs_cluster.c code (which we don't use anymore with UBC). - remove kmem_object and mb_object since they were useless. instead of allocating pages to these objects, we now just allocate pages with no object. such pages are mapped in the kernel until they are freed, so we can use the mapping to find the page to free it. this allows us to remove splvm() protection in several places.
The sum of all these changes improves write throughput on my decstation 5000/200 to within 1% of the rate of NetBSD 1.5 and reduces the elapsed time for "make release" of a NetBSD 1.5 source tree on my 128MB pc to 10% less than a 1.5 kernel took.

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.

Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many architectures), truncate them intelligently instead. The truncation is done centralized in vnode_pager.c. This prevents from wrap-over effects when parts of large (>2^32 byte) files are mmapped. Don't allow to mmap above the numerical range of vm_offset_t. This is considered a temporary solution until the vm system handles the object sizes/offsets more cleanly.

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.

Update the kernhist(9) kernel history code to address issues identified in PR kern/52639, as well as some general cleaning-up...
(As proposed on tech-kern@ with additional changes and enhancements.)
Details of changes:
* All history arguments are now stored as uintmax_t values[1], both in the kernel and in the structures used for exporting the history data to userland via sysctl(9). This avoids problems on some architectures where passing a 64-bit (or larger) value to printf(3) can cause it to process the value as multiple arguments. (This can be particularly problematic when printf()'s format string is not a literal, since in that case the compiler cannot know how large each argument should be.)
* Update the data structures used for exporting kernel history data to include a version number as well as the length of history arguments.
* All [2] existing users of kernhist(9) have had their format strings updated. Each format specifier now includes an explicit length modifier 'j' to refer to numeric values of the size of uintmax_t.
* All [2] existing users of kernhist(9) have had their format strings updated to replace uses of "%p" with "%#jx", and the pointer arguments are now cast to (uintptr_t) before being subsequently cast to (uintmax_t). This is needed to avoid compiler warnings about casting "pointer to integer of a different size."
* All [2] existing users of kernhist(9) have had instances of "%s" or "%c" format strings replaced with numeric formats; several instances of mis-match between format string and argument list have been fixed.
* vmstat(1) has been modified to handle the new size of arguments in the history data as exported by sysctl(9).
* vmstat(1) now provides a warning message if the history requested with the -u option does not exist (previously, this condition was silently ignored, with only a single blank line being printed).
* vmstat(1) now checks the version and argument length included in the data exported via sysctl(9) and exits if they do not match the values with which vmstat was built.
* The kernhist(9) man-page has been updated to note the additional requirements imposed on the format strings, along with several other minor changes and enhancements.
[1] It would have been possible to use an explicit length (for example, uint64_t) for the history arguments. But that would require another "rototill" of all the users in the future when we add support for an architecture that supports a larger size. Also, the printf(3) format specifiers for explicitly-sized values, such as "%"PRIu64, are much more verbose (and less aesthetically appealing, IMHO) than simply using "%ju".
[2] I've tried very hard to find "all [the] existing users of kernhist(9)" but it is possible that I've missed some of them. I would be glad to update any stragglers that anyone identifies.

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.

Make sure all cached buffers with valid, not yet written data have been run through copy-on-write. Call fscow_run() with valid data where possible.
The LP_UFSCOW hack is no longer needed to protect ffs_copyonwrite() against endless recursion.
- Add a flag B_MODIFY to bread(), breada() and breadn(). If set the caller intends to modify the buffer returned.
- Always run copy-on-write on buffers returned from ffs_balloc().
- Add new function ffs_getblk() that gets a buffer, assigns a new blkno, may clear the buffer and runs copy-on-write. Process possible errors from getblk() or fscow_run(). Part of PR kern/38664.

Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD.
- Not enabled by default. Needs kernel option FFS_SNAPSHOT. - Change parameters of ffs_blkfree. - Let the copy-on-write functions return an error so spec_strategy may fail if the copy-on-write fails. - Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock. - Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer. - Add a function ffs_checkfreefile needed for snapshot creation. - Add special handling of snapshot files: Snapshots may not be opened for writing and the attributes are read-only. Use the mtime as the time this snapshot was taken. Deny mtime updates for snapshot files. - Add function transferlockers to transfer any waiting processes from one lock to another. - Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through a vnode. - Add snapshot support to ls, fsck_ffs and dump.

a whole bunch of changes to improve performance and robustness under load:
- remove special treatment of pager_map mappings in pmaps. this is required now, since I've removed the globals that expose the address range. pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's no longer any need to special-case it. - eliminate struct uvm_vnode by moving its fields into struct vnode. - rewrite the pageout path. the pager is now responsible for handling the high-level requests instead of only getting control after a bunch of work has already been done on its behalf. this will allow us to UBCify LFS, which needs tighter control over its pages than other filesystems do. writing a page to disk no longer requires making it read-only, which allows us to write wired pages without causing all kinds of havoc. - use a new PG_PAGEOUT flag to indicate that a page should be freed on behalf of the pagedaemon when it's unlocked. this flag is very similar to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the pageout fails due to eg. an indirect-block buffer being locked. this allows us to remove the "version" field from struct vm_page, and together with shrinking "loan_count" from 32 bits to 16, struct vm_page is now 4 bytes smaller. - no longer use PG_RELEASED for swap-backed pages. if the page is busy because it's being paged out, we can't release the swap slot to be reallocated until that write is complete, but unlike with vnodes we don't keep a count of in-progress writes so there's no good way to know when the write is done. instead, when we need to free a busy swap-backed page, just sleep until we can get it busy ourselves. - implement a fast-path for extending writes which allows us to avoid zeroing new pages. this substantially reduces cpu usage. - encapsulate the data used by the genfs code in a struct genfs_node, which must be the first element of the filesystem-specific vnode data for filesystems which use genfs_{get,put}pages(). - eliminate many of the UVM pagerops, since they aren't needed anymore now that the pager "put" operation is a higher-level operation. - enhance the genfs code to allow NFS to use the genfs_{get,put}pages instead of a modified copy. - clean up struct vnode by removing all the fields that used to be used by the vfs_cluster.c code (which we don't use anymore with UBC). - remove kmem_object and mb_object since they were useless. instead of allocating pages to these objects, we now just allocate pages with no object. such pages are mapped in the kernel until they are freed, so we can use the mapping to find the page to free it. this allows us to remove splvm() protection in several places.
The sum of all these changes improves write throughput on my decstation 5000/200 to within 1% of the rate of NetBSD 1.5 and reduces the elapsed time for "make release" of a NetBSD 1.5 source tree on my 128MB pc to 10% less than a 1.5 kernel took.

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.

Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many architectures), truncate them intelligently instead. The truncation is done centralized in vnode_pager.c. This prevents from wrap-over effects when parts of large (>2^32 byte) files are mmapped. Don't allow to mmap above the numerical range of vm_offset_t. This is considered a temporary solution until the vm system handles the object sizes/offsets more cleanly.

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.

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.

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.

Make sure all cached buffers with valid, not yet written data have been run through copy-on-write. Call fscow_run() with valid data where possible.
The LP_UFSCOW hack is no longer needed to protect ffs_copyonwrite() against endless recursion.
- Add a flag B_MODIFY to bread(), breada() and breadn(). If set the caller intends to modify the buffer returned.
- Always run copy-on-write on buffers returned from ffs_balloc().
- Add new function ffs_getblk() that gets a buffer, assigns a new blkno, may clear the buffer and runs copy-on-write. Process possible errors from getblk() or fscow_run(). Part of PR kern/38664.

Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD.
- Not enabled by default. Needs kernel option FFS_SNAPSHOT. - Change parameters of ffs_blkfree. - Let the copy-on-write functions return an error so spec_strategy may fail if the copy-on-write fails. - Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock. - Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer. - Add a function ffs_checkfreefile needed for snapshot creation. - Add special handling of snapshot files: Snapshots may not be opened for writing and the attributes are read-only. Use the mtime as the time this snapshot was taken. Deny mtime updates for snapshot files. - Add function transferlockers to transfer any waiting processes from one lock to another. - Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through a vnode. - Add snapshot support to ls, fsck_ffs and dump.

a whole bunch of changes to improve performance and robustness under load:
- remove special treatment of pager_map mappings in pmaps. this is required now, since I've removed the globals that expose the address range. pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's no longer any need to special-case it. - eliminate struct uvm_vnode by moving its fields into struct vnode. - rewrite the pageout path. the pager is now responsible for handling the high-level requests instead of only getting control after a bunch of work has already been done on its behalf. this will allow us to UBCify LFS, which needs tighter control over its pages than other filesystems do. writing a page to disk no longer requires making it read-only, which allows us to write wired pages without causing all kinds of havoc. - use a new PG_PAGEOUT flag to indicate that a page should be freed on behalf of the pagedaemon when it's unlocked. this flag is very similar to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the pageout fails due to eg. an indirect-block buffer being locked. this allows us to remove the "version" field from struct vm_page, and together with shrinking "loan_count" from 32 bits to 16, struct vm_page is now 4 bytes smaller. - no longer use PG_RELEASED for swap-backed pages. if the page is busy because it's being paged out, we can't release the swap slot to be reallocated until that write is complete, but unlike with vnodes we don't keep a count of in-progress writes so there's no good way to know when the write is done. instead, when we need to free a busy swap-backed page, just sleep until we can get it busy ourselves. - implement a fast-path for extending writes which allows us to avoid zeroing new pages. this substantially reduces cpu usage. - encapsulate the data used by the genfs code in a struct genfs_node, which must be the first element of the filesystem-specific vnode data for filesystems which use genfs_{get,put}pages(). - eliminate many of the UVM pagerops, since they aren't needed anymore now that the pager "put" operation is a higher-level operation. - enhance the genfs code to allow NFS to use the genfs_{get,put}pages instead of a modified copy. - clean up struct vnode by removing all the fields that used to be used by the vfs_cluster.c code (which we don't use anymore with UBC). - remove kmem_object and mb_object since they were useless. instead of allocating pages to these objects, we now just allocate pages with no object. such pages are mapped in the kernel until they are freed, so we can use the mapping to find the page to free it. this allows us to remove splvm() protection in several places.
The sum of all these changes improves write throughput on my decstation 5000/200 to within 1% of the rate of NetBSD 1.5 and reduces the elapsed time for "make release" of a NetBSD 1.5 source tree on my 128MB pc to 10% less than a 1.5 kernel took.

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.

initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some minor portions derived from the old Mach code. i provided some help getting swap and paging working, and other bug fixes/ideas. chuck silvers <chuq@chuq.com> also provided some other fixes.
this is the rest of the MI portion changes.
this will be KNF'd shortly. :-)

Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many architectures), truncate them intelligently instead. The truncation is done centralized in vnode_pager.c. This prevents from wrap-over effects when parts of large (>2^32 byte) files are mmapped. Don't allow to mmap above the numerical range of vm_offset_t. This is considered a temporary solution until the vm system handles the object sizes/offsets more cleanly.

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.
