If the directory is removed, UFS always need to remove the .. ref, even if the ultimate ref on the parent would not change. The new directory must have a new journal entry for that ref. Otherwise journal processing would not properly account for the parent's reference since it will belong to a removed directory entry.

SVN rev 209717 on 2010-07-06 07:11:04Z by jeff - Handle the truncation of an inode with an effective link count of 0 in the context of the process that reduced the effective count. Previously all truncation as a result of unlink happened in the softdep flush thread. This had the effect of being impossible to rate limit properly with the journal code. Now the process issuing unlinks is suspended when the journal files. This has a side-effect of improving rm performance by allowing more concurrent work. - Handle two cases in inactive, one for effnlink == 0 and another when nlink finally reaches 0. - Eliminate the SPACECOUNTED related code since the truncation is no longer delayed.

SVN rev 194498 on 2009-06-19 17:10:35Z by brooks
Rework the credential code to support larger values of NGROUPS and
NGROUPS_MAX, eliminate ABI dependencies on them, and raise the to 1024
and 1023 respectively. (Previously they were equal, but under a close
reading of POSIX, NGROUPS_MAX was defined to be too large by 1 since it
is the number of supplemental groups, not total number of groups.)
The bulk of the change consists of converting the struct ucred member
cr_groups from a static array to a pointer. Do the equivalent in
kinfo_proc.
Introduce new interfaces crcopysafe() and crsetgroups() for duplicating
a process credential before modifying it and for setting group lists
respectively. Both interfaces take care for the details of allocating
groups array. crsetgroups() takes care of truncating the group list
to the current maximum (NGROUPS) if necessary. In the future,
crsetgroups() may be responsible for insuring invariants such as sorting
the supplemental groups to allow groupmember() to be implemented as a
binary search.
Because we can not change struct xucred without breaking application
ABIs, we leave it alone and introduce a new XU_NGROUPS value which is
always 16 and is to be used or NGRPS as appropriate for things such as
NFS which need to use no more than 16 groups. When feasible, truncate
the group list rather than generating an error.
Minor changes:
- Reduce the number of hand rolled versions of groupmember().
- Do not assign to both cr_gid and cr_groups[0].
- Modify ipfw to cache ucreds instead of part of their contents since
they are immutable once referenced by more than one entity.

SVN rev 192895 on 2009-05-27 14:11:23Z by jamie Add hierarchical jails. A jail may further virtualize its environment by creating a child jail, which is visible to that jail and to any parent jails. Child jails may be restricted more than their parents, but never less. Jail names reflect this hierarchy, being MIB-style dot-separated strings. Every thread now points to a jail, the default being prison0, which contains information about the physical system. Prison0's root directory is the same as rootvnode; its hostname is the same as the global hostname, and its securelevel replaces the global securelevel. Note that the variable "securelevel" has actually gone away, which should not cause any problems for code that properly uses securelevel_gt() and securelevel_ge(). Some jail-related permissions that were kept in global variables and set via sysctls are now per-jail settings. The sysctls still exist for backward compatibility, used only by the now-deprecated jail(2) system call. Approved by: bz (mentor)

SVN rev 191564 on 2009-04-27 16:46:16Z by rmacklem Change the semantics of i_modrev/va_filerev to what is required for the nfsv4 Change attribute. There are 2 changes: 1 - The value now changes on metadata changes as well as data modifications (incremented for IN_CHANGE instead of IN_UPDATE). 2 - It is now saved in spare space in the on-disk i-node so that it survives a crash. Since va_filerev is not passed out into user space, the only current use of va_filerev is in the nfs server, which uses it as the directory cookie verifier. Since this verifier is only passed back to the server by a client verbatim and then the server doesn't check it, changing the semantics should not break anything currently in FreeBSD.

SVN rev 191315 on 2009-04-20 14:36:01Z by kib In ufs_checkpath(), recheck that '..' still points to the inode with the same inode number after VFS_VGET() and relock of the vp. If '..' changed, redo the lookup. To reduce code duplication, move the code to read '..' dirent into the static helper function ufs_dir_dd_ino(). Supply the source inode number as an argument to ufs_checkpath() instead of the source inode itself. The inode is unlocked, thus it might be reclaimed, causing accesses to the freed memory. Use vn_vget_ino() to get the '..' vnode by its inode number, instead of directly code VFS_VGET() and relock, to properly busy the mount point while vp lock is dropped.

SVN rev 188614 on 2009-02-14 21:12:58Z by kib MFC r183070: When downgrading the read-write mount to read-only, do_unmount() sets MNT_RDONLY flag before the VFS_MOUNT() is called. In ufs_inactive() and ufs_itimes_locked(), UFS verifies whether the fs is read-only by checking MNT_RDONLY, but this may cause loss of the IN_MODIFIED flag for inode on the fs being remounted rw->ro. Introduce UFS_RDONLY() struct ufsmount' method that reports the value of the fs_ronly. The later is set to 1 only after the remount is finished.

Add the new kernel-mode NFS Lock Manager. To use it instead of the user-mode lock manager, build a kernel with the NFSLOCKD option and add '-k' to 'rpc_lockd_flags' in rc.conf. Highlights include: * Thread-safe kernel RPC client - many threads can use the same RPC client handle safely with replies being de-multiplexed at the socket upcall (typically driven directly by the NIC interrupt) and handed off to whichever thread matches the reply. For UDP sockets, many RPC clients can share the same socket. This allows the use of a single privileged UDP port number to talk to an arbitrary number of remote hosts. * Single-threaded kernel RPC server. Adding support for multi-threaded server would be relatively straightforward and would follow approximately the Solaris KPI. A single thread should be sufficient for the NLM since it should rarely block in normal operation. * Kernel mode NLM server supporting cancel requests and granted callbacks. I've tested the NLM server reasonably extensively - it passes both my own tests and the NFS Connectathon locking tests running on Solaris, Mac OS X and Ubuntu Linux. * Userland NLM client supported. While the NLM server doesn't have support for the local NFS client's locking needs, it does have to field async replies and granted callbacks from remote NLMs that the local client has contacted. We relay these replies to the userland rpc.lockd over a local domain RPC socket. * Robust deadlock detection for the local lock manager. In particular it will detect deadlocks caused by a lock request that covers more than one blocking request. As required by the NLM protocol, all deadlock detection happens synchronously - a user is guaranteed that if a lock request isn't rejected immediately, the lock will eventually be granted. The old system allowed for a 'deferred deadlock' condition where a blocked lock request could wake up and find that some other deadlock-causing lock owner had beaten them to the lock. * Since both local and remote locks are managed by the same kernel locking code, local and remote processes can safely use file locks for mutual exclusion. Local processes have no fairness advantage compared to remote processes when contending to lock a region that has just been unlocked - the local lock manager enforces a strict first-come first-served model for both local and remote lockers.

VOP_LOCK1() (and so VOP_LOCK()) and VOP_UNLOCK() are only used in conjuction with 'thread' argument passing which is always curthread. Remove the unuseful extra-argument and pass explicitly curthread to lower layer functions, when necessary. KPI results broken by this change, which should affect several ports, so version bumping and manpage update will be further committed. Tested by: kris, pho, Diego Sardina <siarodx at gmail dot com>

vn_lock() is currently only used with the 'curthread' passed as argument. Remove this argument and pass curthread directly to underlying VOP_LOCK1() VFS method. This modify makes the code cleaner and in particular remove an annoying dependence helping next lockmgr() cleanup. KPI results, obviously, changed. Manpage and FreeBSD_version will be updated through further commits. As a side note, would be valuable to say that next commits will address a similar cleanup about VFS methods, in particular vop_lock1 and vop_unlock.

Merge first in a series of TrustedBSD MAC Framework KPI changes
from Mac OS X Leopard--rationalize naming for entry points to
the following general forms:
mac_<object>_<method/action>
mac_<object>_check_<method/action>
The previous naming scheme was inconsistent and mostly
reversed from the new scheme. Also, make object types more
consistent and remove spaces from object types that contain
multiple parts ("posix_sem" -> "posixsem") to make mechanical
parsing easier. Introduce a new "netinet" object type for
certain IPv4/IPv6-related methods. Also simplify, slightly,
some entry point names.
All MAC policy modules will need to be recompiled, and modules
not updates as part of this commit will need to be modified to
conform to the new KPI.

Eliminate now-unused SUSER_ALLOWJAIL arguments to priv_check_cred(); in some cases, move to priv_check() if it was an operation on a thread and no other flags were present. Eliminate caller-side jail exception checking (also now-unused); jail privilege exception code now goes solely in kern_jail.c. We can't yet eliminate suser() due to some cases in the KAME code where a privilege check is performed and then used in many different deferred paths. Do, however, move those prototypes to priv.h.

Work around the shortness of the size argument to vnode_create_vobject() while preserving the binary ABI to filesystem modules in RELENG_6: introduce a new function vnode_create_vobject_off() that takes the size argument as off_t; move all stock file systems to it; re-implement the old vnode_create_vobject() using vnode_create_vobject_off() so that old or binary-only FS modules can work w/o hitting the bug. The trick is to pass a size of 0 to vnode_create_vobject_off() so that it will call VOP_GETATTR() and thus get the actual, untruncated file size even if the calling module still uses the old vnode_create_vobject().

This patch addresses a standards violation issue. The standards say a file's access time should be updated when it gets executed. A while ago the mechanism used to exec was changed to use a more mmap based mechanism and this behavior was broken as a side-effect of that. A new vnode flag is added that gets set when the file gets executed, and the VOP_SETATTR() vnode operation gets called. The underlying filesystem is expected to handle it based on its own semantics, some filesystems don't support access time at all. Those that do should handle it in a way that does not block, does not generate I/O if possible, etc. In particular vn_start_write() has not been called. The UFS code handles it the same way as it would normally handle the access time if a file was read - the IN_ACCESS flag gets set in the inode but no other action happens at this point. The actual time update will happen later during a sync (which handles all the necessary locking). Got me into this: cperciva Discussed with: a lot with bde, a little with kan Showed patches to: phk, jeffr, standards@, arch@ Minor discussion on: arch@

Add a new sysctl, "security.jail.chflags_allowed", which controls the behaviour of chflags within a jail. If set to 0 (the default), then a jailed root user is treated as an unprivileged user; if set to 1, then a jailed root user is treated the same as an unjailed root user. This is necessary to allow "make installworld" to work inside a jail, since it attempts to manipulate the system immutable flag on certain files. Discussed with: csjp, rwatson MFC after: 2 weeks

For snapshots we need all VOP_LOCKs to be exclusive. The "business class upgrade" was implemented in UFS's VOP_LOCK implementation ufs_lock() which is the wrong layer, so move it to ffs_lock(). Also, as long as we have not abandonned advanced vfs-stacking we should not preclude it from happening: instead of implementing a copy locally, use the VOP_LOCK_APV(&ufs) to correctly arrive at vop_stdlock() at the bottom.

It was noticed that we do not change a file's access time when it gets executed. This appears to violate most of the UNIX-ish standards. One example quote from: http://www.opengroup.org/onlinepubs/009695399/functions/exec.html Upon successful completion, the exec functions shall mark for update the st_atime field of the file. If an exec function failed but was able to locate the process image file, whether the st_atime field is marked for update is unspecified. Should the exec function succeed, the process image file shall be considered to have been opened with open(). This appears to take care of it for ufs filesystems, doing the necessary sanity checks (read-only filesystem, etc) without violating any other standards (setting atime for any open appears to be allowed in any standards I could find).

Revert previous commit. The null-pointer function call (a dereference on ia64) was not the result of a change in the vector operations. It was caused by the NFS locking code using a FIFO and those bypassing the vnode. This indirectly caused the panic. The NFS locking code has been changed. Requested by: phk

Fix null-pointer indirect function calls introduced in the previous commit. In the new world order, the transitive closure on the vector operations is not precomputed. As such, it's unsafe to actually use any of the function pointers in an indirect function call. They can be null, and we need to use the default vector in that case. This is mostly a quick fix for the four function pointers that are ed explicitly. A more generic or scalable solution is likely to see the light of day. No pathos on: current@

Back when VOP_* was introduced, we did not have new-style struct initializations but we did have lofty goals and big ideals. Adjust to more contemporary circumstances and gain type checking. Replace the entire vop_t frobbing thing with properly typed structures. The only casualty is that we can not add a new VOP_ method with a loadable module. History has not given us reason to belive this would ever be feasible in the the first place. Eliminate in toto VOCALL(), vop_t, VNODEOP_SET() etc. Give coda correct prototypes and function definitions for all vop_()s. Generate a bit more data from the vnode_if.src file: a struct vop_vector and protype typedefs for all vop methods. Add a new vop_bypass() and make vop_default be a pointer to another struct vop_vector. Remove a lot of vfs_init since vop_vector is ready to use from the compiler. Cast various vop_mumble() to void * with uppercase name, for instance VOP_PANIC, VOP_NULL etc. Implement VCALL() by making vdesc_offset the offsetof() the relevant function pointer in vop_vector. This is disgusting but since the code is generated by a script comparatively safe. The alternative for nullfs etc. would be much worse. Fix up all vnode method vectors to remove casts so they become typesafe. (The bulk of this is generated by scripts)

Move UFS from DEVFS backing to GEOM backing. This eliminates a bunch of vnode overhead (approx 1-2 % speed improvement) and gives us more control over the access to the storage device. Access counts on the underlying device are not correctly tracked and therefore it is possible to read-only mount the same disk device multiple times: syv# mount -p /dev/md0 /var ufs rw 2 2 /dev/ad0 /mnt ufs ro 1 1 /dev/ad0 /mnt2 ufs ro 1 1 /dev/ad0 /mnt3 ufs ro 1 1 Since UFS/FFS is not a synchrousely consistent filesystem (ie: it caches things in RAM) this is not possible with read-write mounts, and the system will correctly reject this. Details: Add a geom consumer and a bufobj pointer to ufsmount. Eliminate the vnode argument from softdep_disk_prewrite(). Pick the vnode out of bp->b_vp for now. Eventually we should find it through bp->b_bufobj->b_private. In the mountcode, use g_vfs_open() once we have used VOP_ACCESS() to check permissions. When upgrading and downgrading between r/o and r/w do the right thing with GEOM access counts. Remove all the workarounds for not being able to do this with VOP_OPEN(). If we are the root mount, drop the exclusive access count until we upgrade to r/w. This allows fsck of the root filesystem and the MNT_RELOAD to work correctly. Set bo_private to the GEOM consumer on the device bufobj. Change the ffs_ops->strategy function to call g_vfs_strategy() In ufs_strategy() directly call the strategy on the disk bufobj. Same in rawread. In ffs_fsync() we will no longer see VCHR device nodes, so remove code which synced the filesystem mounted on it, in case we came there. I'm not sure this code made sense in the first place since we would have taken the specfs route on such a vnode. Redo the highly bogus readblock() function in the snapshot code to something slightly less bogus: Constructing an uio and using physio was really quite a detour. Instead just fill in a bio and ship it down.

The island council met and voted buf_prewrite() home. Give ffs it's own bufobj->bo_ops vector and create a private strategy routine, (currently misnamed for forwards compatibility), which is just a copy of the generic bufstrategy routine except we call softdep_disk_prewrite() directly instead of through the buf_prewrite() indirection. Teach UFS about the need for softdep_disk_prewrite() and call the function directly in FFS. Remove buf_prewrite() from the default bufstrategy() and from the global bio_ops method vector.

When I was a kid my work table was one cluttered mess an cleaning it up were a rather overwhelming task. I soon learned that if you don't know where you're going to store something, at least try to pile it next to something slightly related in the hope that a pattern emerges. Apply the same principle to the ffs/snapshot/softupdates code which have leaked into specfs: Add yet a buf-quasi-method and call it from the only two places I can see it can make a difference and implement the magic in ffs_softdep.c where it belongs. It's not pretty, but at least it's one less layer violated.

Now that the central POSIX.1e ACL code implements functions to generate the inode mode from a default ACL and creation mask, implement ufs_sync_inode_from_acl() using acl_posix1e_newfilemode(). Since ACL_OVERRIDE_MASK/ACL_PRESERVE_MASK are defined, we no longer need to explicitly pass in a "preserve_mask" field: this is implicit in the use of POSIX.1e semantics. Note: this change contains a semantic bugfix for new file creation: we now intersect the ACL-generated mode and the cmode requested by the user process. This means permissions on newly created file objects will now be more conservative. In the future, we may want to provide alternative semantics (similar to Solaris and Linux) in which the ACL mask overrides the umask, permitting ACLs to broaden the rights beyond the requested umask.

Temporarily introduce a new VOP_SPECSTRATEGY operation while I try to sort out disk-io from file-io in the vm/buffer/filesystem space. The intent is to sort VOP_STRATEGY calls into those which operate on "real" vnodes and those which operate on VCHR vnodes. For the latter kind, the call will be changed to VOP_SPECSTRATEGY, possibly conditionally for those places where dual-use happens. Add a default VOP_SPECSTRATEGY method which will call the normal VOP_STRATEGY. First time it is called it will print debugging information. This will only happen if a normal vnode is passed to VOP_SPECSTRATEGY by mistake. Add a real VOP_SPECSTRATEGY in specfs, which does what VOP_STRATEGY does on a VCHR vnode today. Add a new VOP_STRATEGY method in specfs to catch instances where the conversion to VOP_SPECSTRATEGY has not yet happened. Handle the request just like we always did, but first time called print debugging information. Apart up to two instances of console messages per boot, this amounts to a glorified no-op commit. If you get any of the messages on your console I would very much like a copy of them mailed to phk@freebsd.org

Slightly change the semantics of vnode labels for MAC: rather than "refreshing" the label on the vnode before use, just get the label right from inception. For single-label file systems, set the label in the generic VFS getnewvnode() code; for multi-label file systems, leave the labeling up to the file system. With UFS1/2, this means reading the extended attribute during vfs_vget() as the inode is pulled off disk, rather than hitting the extended attributes frequently during operations later, improving performance. This also corrects sematics for shared vnode locks, which were not previously present in the system. This chances the cache coherrency properties WRT out-of-band access to label data, but in an acceptable form. With UFS1, there is a small race condition during automatic extended attribute start -- this is not present with UFS2, and occurs because EAs aren't available at vnode inception. We'll introduce a work around for this shortly. Approved by: re Obtained from: TrustedBSD Project Sponsored by: DARPA, Network Associates Laboratories

Push most UFS ACL behavior behind a check for MNT_ACLS, permitting ACLs to be administratively disabled as needed on UFS/UFS2 file systems. This also has the effect of preventing the slightly more expensive ACL code from running on non-ACL file systems, avoiding storage allocation for ACLs that may be read from disk. MNT_ACLS may be set at mount-time using mount -o acls, or implicitly by setting the FS_ACLS flag using tunefs. On UFS1, you may also have to configure ACL store.

When reading or writing the extended attributes of a special device or fifo in UFS2, the normal ufs_strategy routine needs to be used rather than the spec_strategy or fifo_strategy routine. Thus the ffsext_strategy routine is interposed in the ffs_vnops vectors for special devices and fifo's to pick off this special case. Otherwise it simply falls through to the usual spec_strategy or fifo_strategy routine. Submitted by: Robert Watson <rwatson@FreeBSD.org> Sponsored by: DARPA & NAI Labs.

vfs_syscalls.c: Changed rename(2) to follow the letter of the POSIX spec. POSIX requires rename() to have no effect if its args "resolve to the same existing file". I think "file" can only reasonably be read as referring to the inode, although the rationale and "resolve" seem to say that sameness is at the level of (resolved) directory entries. ext2fs_vnops.c, ufs_vnops.c: Replaced code that gave the historical BSD behaviour of removing one link name by checks that this code is now unreachable. This fixes some races. All vnodes needed to be unlocked for the removal, and locking at another level using something like IN_RENAME was not even attempted, so it was possible for rename(x, y) to return with both x and y removed even without any unlink(2) syscalls (one process can remove x using rename(x, y) and another process can remove y using rename(y, x)).

In order to better support flexible and extensible access control, make a series of modifications to the credential arguments relating to file read and write operations to cliarfy which credential is used for what: - Change fo_read() and fo_write() to accept "active_cred" instead of "cred", and change the semantics of consumers of fo_read() and fo_write() to pass the active credential of the thread requesting an operation rather than the cached file cred. The cached file cred is still available in fo_read() and fo_write() consumers via fp->f_cred. These changes largely in sys_generic.c. For each implementation of fo_read() and fo_write(), update cred usage to reflect this change and maintain current semantics: - badfo_readwrite() unchanged - kqueue_read/write() unchanged pipe_read/write() now authorize MAC using active_cred rather than td->td_ucred - soo_read/write() unchanged - vn_read/write() now authorize MAC using active_cred but VOP_READ/WRITE() with fp->f_cred Modify vn_rdwr() to accept two credential arguments instead of a single credential: active_cred and file_cred. Use active_cred for MAC authorization, and select a credential for use in VOP_READ/WRITE() based on whether file_cred is NULL or not. If file_cred is provided, authorize the VOP using that cred, otherwise the active credential, matching current semantics. Modify current vn_rdwr() consumers to pass a file_cred if used in the context of a struct file, and to always pass active_cred. When vn_rdwr() is used without a file_cred, pass NOCRED. These changes should maintain current semantics for read/write, but avoid a redundant passing of fp->f_cred, as well as making it more clear what the origin of each credential is in file descriptor read/write operations. Follow-up commits will make similar changes to other file descriptor operations, and modify the MAC framework to pass both credentials to MAC policy modules so they can implement either semantic for revocation.

Introduce support for Mandatory Access Control and extensible kernel access control. Instrument UFS to support per-inode MAC labels. In particular, invoke MAC framework entry points for generically supporting the backing of MAC labels into extended attributes. This ends up introducing new vnode operation vector entries point at the MAC framework entry points, as well as some explicit entry point invocations for file and directory creation events so that the MAC framework can push labels to disk before the directory names become persistent (this will work better once EAs in UFS2 are hooked into soft updates). The generic EA MAC entry points support executing with the file system in either single label or multilabel operation, and will fall back to the mount label if multilabel is not specified at mount-time.

Add support to UFS2 to provide storage for extended attributes.
As this code is not actually used by any of the existing
interfaces, it seems unlikely to break anything (famous
last words).
The internal kernel interface to manipulate these attributes
is invoked using two new IO_ flags: IO_NORMAL and IO_EXT.
These flags may be specified in the ioflags word of VOP_READ,
VOP_WRITE, and VOP_TRUNCATE. Specifying IO_NORMAL means that
you want to do I/O to the normal data part of the file and
IO_EXT means that you want to do I/O to the extended attributes
part of the file. IO_NORMAL and IO_EXT are mutually exclusive
for VOP_READ and VOP_WRITE, but may be specified individually
or together in the case of VOP_TRUNCATE. For example, when
removing a file, VOP_TRUNCATE is called with both IO_NORMAL
and IO_EXT set. For backward compatibility, if neither IO_NORMAL
nor IO_EXT is set, then IO_NORMAL is assumed.
Note that the BA_ and IO_ flags have been `merged' so that they
may both be used in the same flags word. This merger is possible
by assigning the IO_ flags to the low sixteen bits and the BA_
flags the high sixteen bits. This works because the high sixteen
bits of the IO_ word is reserved for read-ahead and help with
write clustering so will never be used for flags. This merge
lets us get away from code of the form:
if (ioflags & IO_SYNC)
flags |= BA_SYNC;
For the future, I have considered adding a new field to the
vattr structure, va_extsize. This addition could then be
exported through the stat structure to allow applications to
find out the size of the extended attribute storage and also
would provide a more standard interface for truncating them
(via VOP_SETATTR rather than VOP_TRUNCATE).
I am also contemplating adding a pathconf parameter (for
concreteness, lets call it _PC_MAX_EXTSIZE) which would
let an application determine the maximum size of the extended
atribute storage.

This commit adds basic support for the UFS2 filesystem. The UFS2 filesystem expands the inode to 256 bytes to make space for 64-bit block pointers. It also adds a file-creation time field, an ability to use jumbo blocks per inode to allow extent like pointer density, and space for extended attributes (up to twice the filesystem block size worth of attributes, e.g., on a 16K filesystem, there is space for 32K of attributes). UFS2 fully supports and runs existing UFS1 filesystems. New filesystems built using newfs can be built in either UFS1 or UFS2 format using the -O option. In this commit UFS1 is the default format, so if you want to build UFS2 format filesystems, you must specify -O 2. This default will be changed to UFS2 when UFS2 proves itself to be stable. In this commit the boot code for reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c) as there is insufficient space in the boot block. Once the size of the boot block is increased, this code can be defined. Things to note: the definition of SBSIZE has changed to SBLOCKSIZE. The header file <ufs/ufs/dinode.h> must be included before <ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and ufs_lbn_t. Still TODO: Verify that the first level bootstraps work for all the architectures. Convert the utility ffsinfo to understand UFS2 and test growfs. Add support for the extended attribute storage. Update soft updates to ensure integrity of extended attribute storage. Switch the current extended attribute interfaces to use the extended attribute storage.

Change the suser() API to take advantage of td_ucred as well as do a general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag. Discussed on: smp@

Add a flags parameter to VFS_VGET to pass through the desired locking flags when acquiring a vnode. The immediate purpose is to allow polling lock requests (LK_NOWAIT) needed by soft updates to avoid deadlock when enlisting other processes to help with the background cleanup. For the future it will allow the use of shared locks for read access to vnodes. This change touches a lot of files as it affects most filesystems within the system. It has been well tested on FFS, loopback, and CD-ROM filesystems. only lightly on the others, so if you find a problem there, please let me (mckusick@mckusick.com) know.

Introduce the new 64-bit size disk block, daddr64_t. Change the bio and buffer structures to have daddr64_t bio_pblkno, b_blkno, and b_lblkno fields which allows access to disks larger than a Terabyte in size. This change also requires that the VOP_BMAP vnode operation accept and return daddr64_t blocks. This delta should not affect system operation in any way. It merely sets up the necessary interfaces to allow the development of disk drivers that work with these larger disk block addresses. It also allows for the development of UFS2 which will use 64-bit block addresses.

When downgrading a filesystem from read-write to read-only, operations involving file removal or file update were not always being fully committed to disk. The result was lost files or corrupted file data. This change ensures that the filesystem is properly synced to disk before the filesystem is down-graded. This delta also fixes a long standing bug in which a file open for reading has been unlinked. When the last open reference to the file is closed, the inode is reclaimed by the filesystem. Previously, if the filesystem had been down-graded to read-only, the inode could not be reclaimed, and thus was lost and had to be later recovered by fsck. With this change, such files are found at the time of the down-grade. Normally they will result in the filesystem down-grade failing with `device busy'. If a forcible down-grade is done, then the affected files will be revoked causing the inode to be released and the open file descriptors to begin failing on attempts to read.

Two recent commits in sys/ufs/ufs interacted badly with ext2fs because it shares ufs code. In ufs_fhtovp(), the test on i_effnlink is invalid because ext2fs does not maintain this field. In ufs_close(), i_effnlink is also tested, to determines whether or not to call vn_start_write(). The ufs_fhtovp issue breaks NFS exporting of ext2fs filesystems; I believe the other is harmless. Fix both cases by checking um_i_effnlink_valid in the ufsmount struct, and use i_nlink if necessary. Noticed by: bde Reviewed by: mckusick, bde

When closing the last reference to an unlinked file, it is freed by the inactive routine. Because the freeing causes the filesystem to be modified, the close must be held up during periods when the filesystem is suspended. For snapshots to be consistent across crashes, they must write blocks that they copy and claim those written blocks in their on-disk block pointers before the old blocks that they referenced can be allowed to be written. Close a loophole that allowed unwritten blocks to be skipped when doing ffs_sync with a request to wait for all I/O activity to be completed.

In my first reading of POSIX.1e, I misinterpreted handling of the
ACL_USER_OBJ and ACL_GROUP_OBJ fields, believing that modification of the
access ACL could be used by privileged processes to change file/directory
ownership. In fact, this is incorrect; ACL_*_OBJ (+ ACL_MASK and
ACL_OTHER) should have undefined ae_id fields; this commit attempts
to correct that misunderstanding.
o Modify arguments to vaccess_acl_posix1e() to accept the uid and gid
associated with the vnode, as those can no longer be extracted from
the ACL passed as an argument. Perform all comparisons against
the passed arguments. This actually has the effect of simplifying
a number of components of this call, as well as reducing the indent
level, but now seperates handling of ACL_GROUP_OBJ from ACL_GROUP.
o Modify acl_posix1e_check() to return EINVAL if the ae_id field of
any of the ACL_{USER_OBJ,GROUP_OBJ,MASK,OTHER} entries is a value
other than ACL_UNDEFINED_ID. As a temporary work-around to allow
clean upgrades, set the ae_id field to ACL_UNDEFINED_ID before
each check so that this cannot cause a failure in the short term
(this work-around will be removed when the userland libraries and
utilities are updated to take this change into account).
o Modify ufs_sync_acl_from_inode() so that it forces
ACL_{USER_OBJ,GROUP_OBJ,MASK,OTHER} ae_id fields to ACL_UNDEFINED_ID
when synchronizing the ACL from the inode.
o Modify ufs_sync_inode_from_acl to not propagate uid and gid
information to the inode from the ACL during ACL update. Also
modify the masking of permission bits that may be set from
ALLPERMS to (S_IRWXU|S_IRWXG|S_IRWXO), as ACLs currently do not
carry none-ACCESSPERMS (S_ISUID, S_ISGID, S_ISTXT).
o Modify ufs_getacl() so that when it emulates an access ACL from
the inode, it initializes the ae_id fields to ACL_UNDEFINED_ID.
o Clean up ufs_setacl() substantially since it is no longer possible
to perform chown/chgrp operations using vop_setacl(), so all the
access control for that can be eliminated.
o Modify ufs_access() so that it passes owner uid and gid information
into vaccess_acl_posix1e().

Introduce support for POSIX.1e ACLs on UFS-based file systems. This
implementation is still experimental, and while fairly broadly tested,
is not yet intended for production use. Support for POSIX.1e ACLs on
UFS will not be MFC'd to RELENG_4.
This implementation works by providing implementations of VOP_[GS]ETACL()
for FFS, as well as modifying the appropriate access control and file
creation routines. In this implementation, ACLs are backed into extended
attributes; the base ACL (owner, group, other) permissions remain in the
inode for performance and compatibility reasons, so only the extended and
default ACLs are placed in extended attributes. The logic for ACL
evaluation is provided by the fs-independent kern/kern_acl.c.
o Introduce UFS_ACL, a compile-time configuration option that enables
support for ACLs on FFS (and potentially other UFS-based file systems).
o Introduce ufs_getacl(), ufs_setacl(), ufs_aclcheck(), which
respectively get, set, and check the ACLs on the passed vnode.
o Introduce ufs_sync_acl_from_inode(), ufs_sync_inode_from_acl() to
maintain access control information between inode permissions and
extended attribute data.
o Modify ufs_access() to load a file access ACL and invoke
vaccess_acl_posix1e() if ACLs are available on the file system
o Modify ufs_mkdir() and ufs_makeinode() to associate ACLs with newly
created directories and files, inheriting from the parent directory's
default ACL.
o Enable these new vnode operations and conditionally compiled code
paths if UFS_ACL is defined.
A few notes:
o This implementation is fairly widely tested, but still should be
considered experimental.
o Currently, ACLs are not exported via NFS, instead, the summarizing
file mode/etc from the inode is. This results in conservative
protection behavior, similar to the behavior of ACL-nonaware programs
acting locally.
o It is possible that underlying binary data formats associated with
this implementation may change. Consumers of the implementation
should expect to find their local configuration obsoleted in the
next few months, resulting in possible loss of ACL data during an
upgrade.
o The extended attributes interface and implementation is still
undergoing modification to address portable interface concerns, as
well as performance.
o Many applications do not yet correctly handle ACLs. In general,
due to the POSIX.1e ACL model, behavior of ACL-unaware applications
will be conservative with respects to file protection; some caution
is recommended.
o Instructions for configuring and maintaining ACLs on UFS will be
committed in the near future; in the mean time it is possible to
reference the README included in the last UFS ACL distribution
placed in the TrustedBSD web site:
http://www.TrustedBSD.org/downloads/

Change and clean the mutex lock interface.
mtx_enter(lock, type) becomes:
mtx_lock(lock) for sleep locks (MTX_DEF-initialized locks)
mtx_lock_spin(lock) for spin locks (MTX_SPIN-initialized)
similarily, for releasing a lock, we now have:
mtx_unlock(lock) for MTX_DEF and mtx_unlock_spin(lock) for MTX_SPIN.
We change the caller interface for the two different types of locks
because the semantics are entirely different for each case, and this
makes it explicitly clear and, at the same time, it rids us of the
extra `type' argument.
The enter->lock and exit->unlock change has been made with the idea
that we're "locking data" and not "entering locked code" in mind.
Further, remove all additional "flags" previously passed to the
lock acquire/release routines with the exception of two:
MTX_QUIET and MTX_NOSWITCH
The functionality of these flags is preserved and they can be passed
to the lock/unlock routines by calling the corresponding wrappers:
mtx_{lock, unlock}_flags(lock, flag(s)) and
mtx_{lock, unlock}_spin_flags(lock, flag(s)) for MTX_DEF and MTX_SPIN
locks, respectively.
Re-inline some lock acq/rel code; in the sleep lock case, we only
inline the _obtain_lock()s in order to ensure that the inlined code
fits into a cache line. In the spin lock case, we inline recursion and
actually only perform a function call if we need to spin. This change
has been made with the idea that we generally tend to avoid spin locks
and that also the spin locks that we do have and are heavily used
(i.e. sched_lock) do recurse, and therefore in an effort to reduce
function call overhead for some architectures (such as alpha), we
inline recursion for this case.
Create a new malloc type for the witness code and retire from using
the M_DEV type. The new type is called M_WITNESS and is only declared
if WITNESS is enabled.
Begin cleaning up some machdep/mutex.h code - specifically updated the
"optimized" inlined code in alpha/mutex.h and wrote MTX_LOCK_SPIN
and MTX_UNLOCK_SPIN asm macros for the i386/mutex.h as we presently
need those.
Finally, caught up to the interface changes in all sys code.

Fixed breakage of mknod() in rev.1.48 of ext2_vnops.c and rev.1.126 of ufs_vnops.c: 1) i_ino was confused with i_number, so the inode number passed to VFS_VGET() was usually wrong (usually 0U). 2) ip was dereferenced after vgone() freed it, so the inode number passed to VFS_VGET() was sometimes not even wrong. Bug (1) was usually fatal in ext2_mknod(), since ext2fs doesn't have space for inode 0 on the disk; ino_to_fsba() subtracts 1 from the inode number, so inode number 0U gives a way out of bounds array index. Bug(1) was usually harmless in ufs_mknod(); ino_to_fsba() doesn't subtract 1, and VFS_VGET() reads suitable garbage (all 0's?) from the disk for the invalid inode number 0U; ufs_mknod() returns a wrong vnode, but most callers just vput() it; the correct vnode is eventually obtained by an implicit VFS_VGET() just like it used to be. Bug (2) usually doesn't happen.

o Introduce new VOP_ACCESS() flag VADMIN, allowing file systems to perform "administrative" authorization checks. In most cases, the VADMIN test checks to make sure the credential effective uid is the same as the file owner. o Modify vaccess() to set VADMIN as an available right if the uid is appropriate. o Modify references to uid-based access control operations such that they now always invoke VOP_ACCESS() instead of using hard-coded policy checks. o This allows alternative UFS policies to be implemented by replacing only ufs_access() (such as mandatory system policies). o VOP_ACCESS() requires the caller to hold an exclusive vnode lock on the vnode: I believe that new invocations of VOP_ACCESS() are always called with the lock held. o Some direct checks of the uid remain, largely associated with the QUOTA and SUIDDIR code.

Add a lock structure to vnode structure. Previously it was either allocated separately (nfs, cd9660 etc) or keept as a first element of structure referenced by v_data pointer(ffs). Such organization leads to known problems with stacked filesystems. From this point vop_no*lock*() functions maintain only interlock lock. vop_std*lock*() functions maintain built-in v_lock structure using lockmgr(). vop_sharedlock() is compatible with vop_stdunlock(), but maintains a shared lock on vnode. If filesystem wishes to export lockmgr compatible lock, it can put an address of this lock to v_vnlock field. This indicates that the upper filesystem can take advantage of it and use single lock structure for entire (or part) of stack of vnodes. This field shouldn't be examined or modified by VFS code except for initialization purposes. Reviewed in general by: mckusick

o Add a comment clarifying interaction between jail(), privileged processes, and UFS file flags. Here's what the comment says, for reference: Privileged processes in jail() are permitted to modify arbitrary user flags on files, but are not permitted to modify system flags. In other words, privilege does allow a process in jail to modify user flags for objects that the process does not own, but privilege will not permit the setting of system flags on the file.

Clean up the snapshot code so that it no longer depends on the use of the SF_IMMUTABLE flag to prevent writing. Instead put in explicit checking for the SF_SNAPSHOT flag in the appropriate places. With this change, it is now possible to rename and link to snapshot files. It is also possible to set or clear any of the owner, group, or other read bits on the file, though none of the write or execute bits can be set. There is also an explicit test to prevent the setting or clearing of the SF_SNAPSHOT flag via chflags() or fchflags(). Note also that the modify time cannot be changed as it needs to accurately reflect the time that the snapshot was taken. Submitted by: Robert Watson <rwatson@FreeBSD.org>

This patch corrects the first round of panics and hangs reported with the new snapshot code. Update addaliasu to correctly implement the semantics of the old checkalias function. When a device vnode first comes into existence, check to see if an anonymous vnode for the same device was created at boot time by bdevvp(). If so, adopt the bdevvp vnode rather than creating a new vnode for the device. This corrects a problem which caused the kernel to panic when taking a snapshot of the root filesystem. Change the calling convention of vn_write_suspend_wait() to be the same as vn_start_write(). Split out softdep_flushworklist() from softdep_flushfiles() so that it can be used to clear the work queue when suspending filesystem operations. Access to buffers becomes recursive so that snapshots can recursively traverse their indirect blocks using ffs_copyonwrite() when checking for the need for copy on write when flushing one of their own indirect blocks. This eliminates a deadlock between the syncer daemon and a process taking a snapshot. Ensure that softdep_process_worklist() can never block because of a snapshot being taken. This eliminates a problem with buffer starvation. Cleanup change in ffs_sync() which did not synchronously wait when MNT_WAIT was specified. The result was an unclean filesystem panic when doing forcible unmount with heavy filesystem I/O in progress. Return a zero'ed block when reading a block that was not in use at the time that a snapshot was taken. Normally, these blocks should never be read. However, the readahead code will occationally read them which can cause unexpected behavior. Clean up the debugging code that ensures that no blocks be written on a filesystem while it is suspended. Snapshots must explicitly label the blocks that they are writing during the suspension so that they do not cause a `write on suspended filesystem' panic. Reorganize ffs_copyonwrite() to eliminate a deadlock and also to prevent a race condition that would permit the same block to be copied twice. This change eliminates an unexpected soft updates inconsistency in fsck caused by the double allocation. Use bqrelse rather than brelse for buffers that will be needed soon again by the snapshot code. This improves snapshot performance.

Add snapshots to the fast filesystem. Most of the changes support the gating of system calls that cause modifications to the underlying filesystem. The gating can be enabled by any filesystem that needs to consistently suspend operations by adding the vop_stdgetwritemount to their set of vnops. Once gating is enabled, the function vfs_write_suspend stops all new write operations to a filesystem, allows any filesystem modifying system calls already in progress to complete, then sync's the filesystem to disk and returns. The function vfs_write_resume allows the suspended write operations to begin again. Gating is not added by default for all filesystems as for SMP systems it adds two extra locks to such critical kernel paths as the write system call. Thus, gating should only be added as needed. Details on the use and current status of snapshots in FFS can be found in /sys/ufs/ffs/README.snapshot so for brevity and timelyness is not included here. Unless and until you create a snapshot file, these changes should have no effect on your system (famous last words).

Introduce extended attribute support for FFS, allowing arbitrary

used for ACLs, MAC labels, and Capabilities in the TrustedBSD
security extensions, which are currently under development.
In this implementation, attributes are backed to data vnodes in the
style of the quota support in FFS. Support for FFS extended
attributes may be enabled using the FFS_EXTATTR kernel option
(disabled by default). Userland utilities and man pages will be
committed in the next batch. VFS interfaces and man pages have
been in the repo since 4.0-RELEASE and are unchanged.

After much consulting with bde, concluded that this fix was the best fix to the current jail/chflags interactions. This fix conditionalizes ``root behavior'' in the chflags() case on not being in jail, so attempts to perform a chflags in a jail are limited to what a normal user could do. For example, this does allow setting of user flags as appropriate, but prohibits changing of system flags. Reviewed by: bde

Several performance improvements for soft updates have been added: 1) Fastpath deletions. When a file is being deleted, check to see if it was so recently created that its inode has not yet been written to disk. If so, the delete can proceed to immediately free the inode. 2) Background writes: No file or block allocations can be done while the bitmap is being written to disk. To avoid these stalls, the bitmap is copied to another buffer which is written thus leaving the original available for futher allocations. 3) Link count tracking. Constantly track the difference in i_effnlink and i_nlink so that inodes that have had no change other than i_effnlink need not be written. 4) Identify buffers with rollback dependencies so that the buffer flushing daemon can choose to skip over them.

Simplify the handling of VCHR and VBLK vnodes using the new dev_t:
Make the alias list a SLIST.
Drop the "fast recycling" optimization of vnodes (including
the returning of a prexisting but stale vnode from checkalias).
It doesn't buy us anything now that we don't hardlimit
vnodes anymore.
Rename checkalias2() and checkalias() to addalias() and
addaliasu() - which takes dev_t and udev_t arg respectively.
Make the revoke syscalls use vcount() instead of VALIASED.
Remove VALIASED flag, we don't need it now and it is faster
to traverse the much shorter lists than to maintain the
flag.
vfs_mountedon() can check the dev_t directly, all the vnodes
point to the same one.
Print the devicename in specfs/vprint().
Remove a couple of stale LFS vnode flags.
Remove unimplemented/unused LK_DRAINED;

Support full-precision file timestamps. Until now, only the seconds
have been maintained, and that is still the default. A new sysctl
variable "vfs.timestamp_precision" can be used to enable higher
levels of precision:
0 = seconds only; nanoseconds zeroed (default).
1 = seconds and nanoseconds, accurate within 1/HZ.
2 = seconds and nanoseconds, truncated to microseconds.
>=3 = seconds and nanoseconds, maximum precision.
Level 1 uses getnanotime(), which is fast but can be wrong by up
to 1/HZ. Level 2 uses microtime(). It might be desirable for
consistency with utimes() and friends, which take timeval structures
rather than timespecs. Level 3 uses nanotime() for the higest
precision.
I benchmarked levels 0, 1, and 3 by copying a 550 MB tree with
"cpio -pdu". There was almost negligible difference in the system
times -- much less than 1%, and less than the variation among
multiple runs at the same level. Bruce Evans dreamed up a torture
test involving 1-byte reads with intervening fstat() calls, but
the cpio test seems more realistic to me.
This feature is currently implemented only for the UFS (FFS and
MFS) filesystems. But I think it should be easy to support it in
the others as well.
An earlier version of this was reviewed by Bruce. He's not to
blame for any breakage I've introduced since then.

Divorce "dev_t" from the "major|minor" bitmap, which is now called
udev_t in the kernel but still called dev_t in userland.
Provide functions to manipulate both types:
major() umajor()
minor() uminor()
makedev() umakedev()
dev2udev() udev2dev()
For now they're functions, they will become in-line functions
after one of the next two steps in this process.
Return major/minor/makedev to macro-hood for userland.
Register a name in cdevsw[] for the "filedescriptor" driver.
In the kernel the udev_t appears in places where we have the
major/minor number combination, (ie: a potential device: we
may not have the driver nor the device), like in inodes, vattr,
cdevsw registration and so on, whereas the dev_t appears where
we carry around a reference to a actual device.
In the future the cdevsw and the aliased-from vnode will be hung
directly from the dev_t, along with up to two softc pointers for
the device driver and a few houskeeping bits. This will essentially
replace the current "alias" check code (same buck, bigger bang).
A little stunt has been provided to try to catch places where the
wrong type is being used (dev_t vs udev_t), if you see something
not working, #undef DEVT_FASCIST in kern/kern_conf.c and see if
it makes a difference. If it does, please try to track it down
(many hands make light work) or at least try to reproduce it
as simply as possible, and describe how to do that.
Without DEVT_FASCIST I belive this patch is a no-op.
Stylistic/posixoid comments about the userland view of the <sys/*.h>
files welcome now, from userland they now contain the end result.
Next planned step: make all dev_t's refer to the same devsw[] which
means convert BLK's to CHR's at the perimeter of the vnodes and
other places where they enter the game (bootdev, mknod, sysctl).

This Implements the mumbled about "Jail" feature. This is a seriously beefed up chroot kind of thing. The process is jailed along the same lines as a chroot does it, but with additional tough restrictions imposed on what the superuser can do. For all I know, it is safe to hand over the root bit inside a prison to the customer living in that prison, this is what it was developed for in fact: "real virtual servers". Each prison has an ip number associated with it, which all IP communications will be coerced to use and each prison has its own hostname. Needless to say, you need more RAM this way, but the advantage is that each customer can run their own particular version of apache and not stomp on the toes of their neighbors. It generally does what one would expect, but setting up a jail still takes a little knowledge. A few notes: I have no scripts for setting up a jail, don't ask me for them. The IP number should be an alias on one of the interfaces. mount a /proc in each jail, it will make ps more useable. /proc/<pid>/status tells the hostname of the prison for jailed processes. Quotas are only sensible if you have a mountpoint per prison. There are no privisions for stopping resource-hogging. Some "#ifdef INET" and similar may be missing (send patches!) If somebody wants to take it from here and develop it into more of a "virtual machine" they should be most welcome! Tools, comments, patches & documentation most welcome. Have fun...

Fix last commit based on feedback from Guido, Bruce and Terry. Specifically, the test was in the wrong place, lacked a cast, didn't unlock the node, and exited to bad rather than abortit. Now we don't allow renaming of a file with LINK_MAX references. Move the test to earlier in the code as it is closer to where ip is obtained, as that is the style of the rest of the function. Didn't fix the problems bruce pointed out in the rename man page to include EMLINK, nor address his complaints about how the whole idea of incrementing the link count during a rename is potentially asking for trouble. Also didn't try to correct potential problem Terry pointed out with decrements not being similarly protected against underflow.

Null change. Forgot to mention in previous log message that MNT_NOATIME is now ignored for special files, so that mounting root with option noatime doesn't break reporting of idle times in programs like `w'. The problem of execessive disk updates just to stamp atimes will be handled for special files by only writing atimes to disk when inodes become active. This works well because special files are relatively uncommon and their atimes are even more disposable at panic time than regular files' atimes.

Fixed some longstanding timestamp bugs: 1. mark atimes and mtimes of special files and fifos for update upon successful completion of non-null i/o, not at the beginning of the syscall. 2. never update file times for readonly filesystems. They were updated for stats and closes but not for syncs. The updates were of course only in-core and were thrown away when the inode was uncached, so the times sometimes appeared to go backwards. Improved comments in code related to (1) (mostly by removing them). Unmacroized ITIMES(). The test in (2) bloated it even more. Don't call getmicrotime() in the function version of it when we only need the time in seconds.

In the words of the submitter: --------- Make callers of namei() responsible for releasing references or locks instead of having the underlying filesystems do it. This eliminates redundancy in all terminal filesystems and makes it possible for stacked transport layers such as umapfs or nullfs to operate correctly. Quality testing was done with testvn, and lat_fs from the lmbench suite. Some NFS client testing courtesy of Patrik Kudo. vop_mknod and vop_symlink still release the returned vpp. vop_rename still releases 4 vnode arguments before it returns. These remaining cases will be corrected in the next set of patches. --------- Submitted by: Michael Hancock <michaelh@cet.co.jp>

Eradicate the variable "time" from the kernel, using various measures. "time" wasn't a atomic variable, so splfoo() protection were needed around any access to it, unless you just wanted the seconds part. Most uses of time.tv_sec now uses the new variable time_second instead. gettime() changed to getmicrotime(0. Remove a couple of unneeded splfoo() protections, the new getmicrotime() is atomic, (until Bruce sets a breakpoint in it). A couple of places needed random data, so use read_random() instead of mucking about with time which isn't random. Add a new nfs_curusec() function. Mark a couple of bogosities involving the now disappeard time variable. Update ffs_update() to avoid the weird "== &time" checks, by fixing the one remaining call that passwd &time as args. Change profiling in ncr.c to use ticks instead of time. Resolution is the same. Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call hzto() which subtracts time" sequences.

Add support for poll(2) on files. vop_nopoll() now returns POLLNVAL if one of the new poll types is requested; hopefully this will not break any existing code. (This is done so that programs have a dependable way of determining whether a filesystem supports the extended poll types or not.) The new poll types added are: POLLWRITE - file contents may have been modified POLLNLINK - file was linked, unlinked, or renamed POLLATTRIB - file's attributes may have been changed POLLEXTEND - file was extended Note that the internal operation of poll() means that it is impossible for two processes to reliably poll for the same event (this could be fixed but may not be worth it), so it is not possible to rewrite `tail -f' to use poll at this time.

Fixed marking of access time for special files and fifos (don't do it if the file system is mounted noatime). Not fixed: the access time is marked at the start of a read() and not marked on successful completion. I think this should be handled at the vfs level. Print a better panic message for missing vops. Don't use printf() before panic(), since the printf()ed part isn't shown by gdb. This actually loses a little with the current gdb, since gdb just prints the fmt arg to panic, so %'s aren't expanded. gdb should fetch the full message from the message buffer if possible. Fixed default vop function for vop_getpages_desc. It needs to just return EOPNOTSUPP so that the vnode pager can get the pages in using a general method. Panicing broke exec'ing of files on ext2fs file systems. ffs works because it doesn't use the default. Fixed nearby style bugs.

VOP_CLOSE vop_null
VOP_FSYNC vop_null
VOP_IOCTL vop_enotty
VOP_MMAP vop_einval
VOP_OPEN vop_null
VOP_PATHCONF vop_einval
VOP_READLINK vop_einval
VOP_REALLOCBLKS vop_eopnotsupp
And remove identical functionality from filesystems
4. Add vop_stdpathconf, which returns the canonical stuff. Use
it in the filesystems. (XXX: It's probably wrong that specfs
and fifofs sets this vop, shouldn't it come from the "host"
filesystem, for instance ufs or cd9660 ?)
5. Try to make system wide VOP functions have vop_* names.
6. Initialize the um_* vectors in LFS.

VFS mega cleanup commit (x/N)
1. Add new file "sys/kern/vfs_default.c" where default actions for
VOPs go. Implement proper defaults for ABORTOP, BWRITE, LEASE,
POLL, REVOKE and STRATEGY. Various stuff spread over the entire
tree belongs here.
2. Change VOP_BLKATOFF to a normal function in cd9660.
3. Kill VOP_BLKATOFF, VOP_TRUNCATE, VOP_VFREE, VOP_VALLOC. These
are private interface functions between UFS and the underlying
storage manager layer (FFS/LFS/MFS/EXT2FS). The functions now
live in struct ufsmount instead.
4. Remove a kludge of VOP_ functions in all filesystems, that did
nothing but obscure the simplicity and break the expandability.
If a filesystem doesn't implement VOP_FOO, it shouldn't have an
entry for it in its vnops table. The system will try to DTRT
if it is not implemented. There are still some cruft left, but
the bulk of it is done.
5. Fix another VCALL in vfs_cache.c (thanks Bruce!)

Always mark st_ctime for update upon successful completion of chown(). Previously, it wasn't marked for null chown()'s. We permit null chown()s as a special case of "appropriate privilege" - everyone has enough priviilege to not change ids (this is a better argument than the one I gave for rev.1.13, that null changes aren't really changes). However, POSIX.1 requires the update independently of whether anything has changed. Clear both the setuid and the setgid bits upon successful completion of non-null chown()s by non-root. Previously, the setuid bit was only changed for non-null changes of the uid, etc. POSIX.1 requires clearing both unless the call was made by a process with "appropriate privilege", in which case altering the bits is implementation-defined. We define appropriate privilege as `process is root, or the change is null', and the implementation-defined behaviour as not altering the bits. There is no interpretation that permits clearing only one of the bits. Reviewed by: jdp

Submitted by: Whistle Communications (archie Cobbs) These changes add the ability to specify that a UFS file/directory cannot be unlinked. This is basically a scaled back version of the IMMUTABLE flag. The reason is to allow an administrator to create a directory hierarchy that a group of users can arbitrarily add/delete files from, but that the hierarchy itself is safe from removal by them. If the NOUNLINK definition is set to 0 then this results in no change to what happens normally. (and results in identical binary (in the kernel)). It can be proven that if this bit is never set by the admin, no new behaviour is introduced.. Several "good idea" comments from reviewers plus one grumble about creeping featurism. This code is in production in 2.2 based systems

Treat symlinks as first class citizens with their own uid/gid rather than as shadows of their containing directory. This should solve the problem of users not being able to delete their symlinks from /tmp once and for all. Symlinks do not have modes though, they are accessable to everything that can read the directory (as before). They are made to show this fact at lstat time (they appear as mode 0777 always, since that's how the the lookup routines in the kernel treat them). More commits will follow, eg: add a real lchown() syscall and man pages.

Fixed some races and misleading comments in ufs_rename(). 1. When a directory is renamed to an existing (empty) directory, it is possible for the target vnode to become the source vnode underneath you (because another process may complete the same rename). It was assumed that this can't happen, and the bogus errno EINVAL was returned. This was fairly harmless. Fix: return ENOENT instead, as if the source directory was renamed a little earlier. 2. The same metamorphosis is possible for non-directories. It was assumed that this can't happen, and the code for handling "just removing a link name" happened to be used. This would have worked except for fatal bugs in the link name removal - the link name was assumed to still be there, and a null pointer was followed. Fix: check the result of relookup(). This fixes PR 1930. Notes: (a) POSIX seems to say that removing link names shall have no effect. BSD (4.4Lite2 at least) does something reasonable instead. (b) The relookup() may find a file unrelated to the original. Removing this isn't correct. Consider 3 existing files A, B and C, and concurrent renames: AB = rename(A, B), another AB, and CA = rename("c", "a"). If rename() is atomic, then only the following results are possible: AB, AB (fails), CA: A = original C, B = original A, C = gone AB, CA, AB: A = gone, B = original C, C = gone CA, AB, AB (fails): A = gone, B = original C, C = gone but ufs_rename() can give: A,AB,CA,B (sorta): A = gone, B = original A, C = gone This usually doesn't matter, since getting into a race is usually an error. --- These fixes should be in 2.1.6 and 2.2.

Eliminated many redundant vm_map_lookup operations for vm_mmap. Speed up for vfs_bio -- addition of a routine bqrelse to greatly diminish overhead for merged cache. Efficiency improvement for vfs_cluster. It used to do alot of redundant calls to cluster_rbuild. Correct the ordering for vrele of .text and release of credentials. Use the selective tlb update for 486/586/P6. Numerous fixes to the size of objects allocated for files. Additionally, fixes in the various pagers. Fixes for proper positioning of vnode_pager_setsize in msdosfs and ext2fs. Fixes in the swap pager for exhausted resources. The pageout code will not as readily thrash. Change the page queue flags (PG_ACTIVE, PG_INACTIVE, PG_FREE, PG_CACHE) into page queue indices (PQ_ACTIVE, PQ_INACTIVE, PQ_FREE, PQ_CACHE), thereby improving efficiency of several routines. Eliminate even more unnecessary vm_page_protect operations. Significantly speed up process forks. Make vm_object_page_clean more efficient, thereby eliminating the pause that happens every 30seconds. Make sequential clustered writes B_ASYNC instead of B_DELWRI even in the case of filesystems mounted async. Fix a panic with busy pages when write clustering is done for non-VMIO buffers.

Introduced a type `vop_t' for vnode operation functions and used it 1138 times (:-() in casts and a few more times in declarations. This change is null for the i386. The type has to be `typedef int vop_t(void *)' and not `typedef int vop_t()' because `gcc -Wstrict-prototypes' warns about the latter. Since vnode op functions are called with args of different (struct pointer) types, neither of these function types is any use for type checking of the arg, so it would be preferable not to use the complete function type, especially since using the complete type requires adding 1138 casts to avoid compiler warnings and another 40+ casts to reverse the function pointer conversions before calling the functions.

Reviewed by: julian with quick glances by bruce and others Submitted by: terry (terry lambert) This is a composite of 3 patch sets submitted by terry. they are: New low-level init code that supports loadbal modules better some cleanups in the namei code to help terry in 16-bit character support some changes to the mount-root code to make it a little more modular.. NOTE: mounting root off cdrom or NFS MIGHT be broken as I haven't been able to test those cases.. certainly mounting root of disk still works just fine.. mfs should work but is untested. (tomorrows task) The low level init stuff includes a total rewrite of init_main.c to make it possible for new modules to have an init phase by simply adding an entry to a TEXT_SET (or is it DATA_SET) list. thus a new module can be added to the kernel without editing any other files other than the 'files' file.

Changes from John Dyson and myself: Fixed remaining known bugs in the buffer IO and VM system. vfs_bio.c: Fixed some race conditions and locking bugs. Improved performance by removing some (now) unnecessary code and fixing some broken logic. Fixed process accounting of # of FS outputs. Properly handle NFS interrupts (B_EINTR). (various) Replaced calls to clrbuf() with calls to an optimized routine called vfs_bio_clrbuf(). (various FS sync) Sync out modified vnode_pager backed pages. ffs_vnops.c: Do two passes: Sync out file data first, then indirect blocks. vm_fault.c: Fixed deadly embrace caused by acquiring locks in the wrong order. vnode_pager.c: Changed to use buffer I/O system for writing out modified pages. This should fix the problem with the modification date previous not getting updated. Also dramatically simplifies the code. Note that this is going to change in the future and be implemented via VOP_PUTPAGES(). vm_object.c: Fixed a pile of bugs related to cleaning (vnode) objects. The performance of vm_object_page_clean() is terrible when dealing with huge objects, but this will change when we implement a binary tree to keep the object pages sorted. vm_pageout.c: Fixed broken clustering of pageouts. Fixed race conditions and other lockup style bugs in the scanning of pages. Improved performance.

These changes embody the support of the fully coherent merged VM buffer cache, much higher filesystem I/O performance, and much better paging performance. It represents the culmination of over 6 months of R&D. The majority of the merged VM/cache work is by John Dyson. The following highlights the most significant changes. Additionally, there are (mostly minor) changes to the various filesystem modules (nfs, msdosfs, etc) to support the new VM/buffer scheme. vfs_bio.c: Significant rewrite of most of vfs_bio to support the merged VM buffer cache scheme. The scheme is almost fully compatible with the old filesystem interface. Significant improvement in the number of opportunities for write clustering. vfs_cluster.c, vfs_subr.c Upgrade and performance enhancements in vfs layer code to support merged VM/buffer cache. Fixup of vfs_cluster to eliminate the bogus pagemove stuff. vm_object.c: Yet more improvements in the collapse code. Elimination of some windows that can cause list corruption. vm_pageout.c: Fixed it, it really works better now. Somehow in 2.0, some "enhancements" broke the code. This code has been reworked from the ground-up. vm_fault.c, vm_page.c, pmap.c, vm_object.c Support for small-block filesystems with merged VM/buffer cache scheme. pmap.c vm_map.c Dynamic kernel VM size, now we dont have to pre-allocate excessive numbers of kernel PTs. vm_glue.c Much simpler and more effective swapping code. No more gratuitous swapping. proc.h Fixed the problem that the p_lock flag was not being cleared on a fork. swap_pager.c, vnode_pager.c Removal of old vfs_bio cruft to support the past pseudo-coherency. Now the code doesn't need it anymore. machdep.c Changes to better support the parameter values for the merged VM/buffer cache scheme. machdep.c, kern_exec.c, vm_glue.c Implemented a seperate submap for temporary exec string space and another one to contain process upages. This eliminates all map fragmentation problems that previously existed. ffs_inode.c, ufs_inode.c, ufs_readwrite.c Changes for merged VM/buffer cache. Add "bypass" support for sneaking in on busy buffers. Submitted by: John Dyson and David Greenman
