Candidate fix for problems with hanging after kva fragmentation related to PR kern/45718. Proposed on tech-kern: https://mail-index.NetBSD.org/tech-kern/2017/10/23/msg022472.html Tested by bouyer@ on i386. This makes one small change to the semantics of pool_prime and pool_setlowat: they may fail with EWOULDBLOCK instead of ENOMEM, if there is a pending call to the backing allocator in another thread but we are not actually out of memory. That is unlikely because nearly always these are used during initialization, when the pool is not in use. Define the new flag too for previous commit. pool_grow can now fail even when sleeping is ok. Catch this case in pool_get and retry. Assert that pool_get failure happens only with PR_NOWAIT. This would have caught the mistake I made last week leading to null pointer dereferences all over the place, a mistake which I evidently poorly scheduled alongside maxv's change to the panic message on x86 for null pointer dereferences. Since pr_lock is now used to wait for two things now (PR_GROWING and PR_WANTED) we need to loop for the condition we wanted. make the KASSERTMSG/panic strings consistent as '%s: [%s], __func__, wchan' Handle the ERESTART case from pool_grow() don't pass 0 to the pool flags Guess pool_cache_get(pc, 0) means PR_WAITOK here. Earlier on in the same context we use kmem_alloc(sz, KM_SLEEP). use PR_WAITOK everywhere. use PR_NOWAIT. Don't use 0 for PR_NOWAIT use PR_NOWAIT instead of 0 panic ex nihilo -- PR_NOWAITing for zerot Add assertions that either PR_WAITOK or PR_NOWAIT are set. - fix an assert; we can reach there if we are nowait or limitfail. - when priming the pool and failing with ERESTART, don't decrement the number of pages; this avoids the issue of returning an ERESTART when we get to 0, and is more correct. - simplify the pool_grow code, and don't wakeup things if we ENOMEM. In pmap_enter_ma(), only try to allocate pves if we might need them, and even if that fails, only fail the operation if we later discover that we really do need them. This implements the requirement that pmap_enter(PMAP_CANFAIL) must not fail when replacing an existing mapping with the first mapping of a new page, which is an unintended consequence of the changes from the rmind-uvmplock branch in 2011. The problem arises when pmap_enter(PMAP_CANFAIL) is used to replace an existing pmap mapping with a mapping of a different page (eg. to resolve a copy-on-write). If that fails and leaves the old pmap entry in place, then UVM won't hold the right locks when it eventually retries. This entanglement of the UVM and pmap locking was done in rmind-uvmplock in order to improve performance, but it also means that the UVM state and pmap state need to be kept in sync more than they did before. It would be possible to handle this in the UVM code instead of in the pmap code, but these pmap changes improve the handling of low memory situations in general, and handling this in UVM would be clunky, so this seemed like the better way to go. This somewhat indirectly fixes PR 52706, as well as the failing assertion about "uvm_page_locked_p(old_pg)". (but only on x86, various other platforms will need their own changes to handle this issue.) In uvm_fault_upper_enter(), if pmap_enter(PMAP_CANFAIL) fails, assert that the pmap did not leave around a now-stale pmap mapping for an old page. If such a pmap mapping still existed after we unlocked the vm_map, the UVM code would not know later that it would need to lock the lower layer object while calling the pmap to remove or replace that stale pmap mapping. See PR 52706 for further details. hopefully workaround the irregularly "fork fails in init" problem. if a pool is growing, and the grower is PR_NOWAIT, mark this. if another caller wants to grow the pool and is also PR_NOWAIT, busy-wait for the original caller, which should either succeed or hard-fail fairly quickly. implement the busy-wait by unlocking and relocking this pools mutex and returning ERESTART. other methods (such as having the caller do this) were significantly more code and this hack is fairly localised. ok chs@ riastradh@ Don't release the lock in the PR_NOWAIT allocation. Move flags setting after the acquiring the mutex. (from Tobias Nygren) apply the change from arch/x86/x86/pmap.c rev. 1.266 commitid vZRjvmxG7YTHLOfA: In pmap_enter_ma(), only try to allocate pves if we might need them, and even if that fails, only fail the operation if we later discover that we really do need them. If we are replacing an existing mapping, reuse the pv structure where possible. This implements the requirement that pmap_enter(PMAP_CANFAIL) must not fail when replacing an existing mapping with the first mapping of a new page, which is an unintended consequence of the changes from the rmind-uvmplock branch in 2011. The problem arises when pmap_enter(PMAP_CANFAIL) is used to replace an existing pmap mapping with a mapping of a different page (eg. to resolve a copy-on-write).

It would be possible to handle this in the UVM code instead of in the pmap code, but these pmap changes improve the handling of low memory situations in general, and handling this in UVM would be clunky, so this seemed like the better way to go. This somewhat indirectly fixes PR 52706 on the remaining platforms where this problem existed.

1.5	05-Sep-2020	riastradh	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. ok chs@

1.12	23-Apr-2020	ad	PR kern/54759 (vm.ubc_direct deadlock when read()/write() into mapping of itself) - Add new flag UBC_ISMAPPED which tells ubc_uiomove() the object is mmap()ed somewhere. Use it to decide whether to do direct-mapped copy, rather than poking around directly in the vnode in ubc_uiomove(), which is ugly and doesn't work for tmpfs. It would be nicer to contain all this in UVM but the filesystem provides the needed locking here (VV_MAPPED) and to reinvent that would suck more. - Rename UBC_UNMAP_FLAG() to UBC_VNODE_FLAGS(). Pass in UBC_ISMAPPED where appropriate.

Otherwise a (un)privileged user can easily panic the system by passing a huge size. ok christos@ An (un)privileged user can easily make the kernel dereference a NULL pointer. The kernel allows 'data' to be NULL; it's the fs's responsibility to ensure that it isn't NULL (if the fs actually needs data). ok christos@ Some fs's - like kernfs - set their vfs_min_mount_data to zero. Add a check to prevent an (un)privileged user from requesting a zero-sized allocation (and thus a panic).

1.15.2.1	20-Jul-2016	pgoyette	Adapt machine-independant code to the new {b,c}devsw reference-counting (using localcount(9)). All callers of {b,c}devsw_lookup() now call {b,c}devsw_lookup_acquire() which retains a reference on the 'struct {b,c}devsw'. This reference must be released by the caller once it is finished with the structure's content (or other data that would disappear if the 'struct {b,c}devsw' were to disappear).
1.16.4.1	27-Apr-2017	pgoyette	Restore all work from the former pgoyette-localcount branch (which is now abandoned doe to cvs merge botch). The branch now builds, and installs via anita. There are still some problems (cgd is non-functional and all atf tests time-out) but they will get resolved soon.

1.48	27-Mar-2022	christos	add a kauth vnode check for creating links
1.47	07-Dec-2021	andvar	fix various typos, mainly in comments.
1.46	20-Oct-2021	thorpej	Overhaul of the EVFILT_VNODE kevent(2) filter: - Centralize vnode kevent handling in the VOP_() wrappers, rather than forcing each individual file system to deal with it (except VOP_RENAME(), because VOP_RENAME() is a mess and we currently have 2 different ways of handling it; at least it's reasonably well-centralized in the "new" way). - Add support for NOTE_OPEN, NOTE_CLOSE, NOTE_CLOSE_WRITE, and NOTE_READ, compatible with the same events in FreeBSD. - Track which kevent notifications clients are interested in receiving to avoid doing work for events no one cares about (avoiding, e.g. taking locks and traversing the klist to send a NOTE_WRITE when someone is merely watching for a file to be deleted, for example). In support of the above: - Add support in vnode_if.sh for specifying PRE- and POST-op handlers, to be invoked before and after vop_pre() and vop_post(), respectively. Basic idea from FreeBSD, but implemented differently. - Add support in vnode_if.sh for specifying CONTEXT fields in the vop__args structures. These context fields are used to convey information between the file system VOP function and the VOP wrapper, but do not occupy an argument slot in the VOP_*() call itself. These context fields are initialized and subsequently interpreted by PRE- and POST-op handlers. - Version VOP_REMOVE(), uses the a context field for the file system to report back the resulting link count of the target vnode. Return this in tmpfs, udf, nfs, chfs, ext2fs, lfs, and ufs. NetBSD 9.99.92.
1.45	18-Jul-2021	dholland	Use macros for the canned parts of device and fifo vnode op tables. Add GENFS_SPECOP_ENTRIES and GENFS_FIFOOP_ENTRIES macros that contain the portion of the vnode ops table declaration that is (conservatively) the same in every fs. Use these in every fs that supports devices and/or fifos with separate ops tables. Note that ptyfs works differently (it has one type of vnode with open-coded dispatch to the specfs code, which I haven't changed in this commit) and rump/librump/rumpvfs/rumpfs.c has an indirect dynamic dispatch that already does more or less the same thing, which I also haven't changed. Also note that this anticipates a few bits in the next changeset here and there, and adds missing but unreachable calls in some cases (e.g. most fses weren't defining whiteout on devices and fifos, but it isn't reachable there), and it changes parsepath on devices and fifos to genfs_badop from genfs_parsepath (but it's not reachable there either). It appears that devices in kernfs were missing kqfilter, so it's possible that if you try to use kqueue on /kern/rootdev that it'll explode. And finally note that the ops declaration tables aren't order-dependent. (Other than vop_default_desc has to come first.) Otherwise this wouldn't work.
1.44	05-Jul-2021	dholland	whitespace
1.43	29-Jun-2021	dholland	- Add a new vnode op: VOP_PARSEPATH. - Move namei_getcomponent to genfs_vnops.c and call it genfs_parsepath. - Add a parsepath entry to every vnode ops table. VOP_PARSEPATH takes a directory vnode to be searched and a complete following path and chooses how much of that path to consume. To begin with, all parsepath calls are genfs_parsepath, which locates the first '/' as always. Note that the call doesn't take the whole struct componentname, only the string. The other bits of struct componentname should not be needed and there's no reason to cause potential complications by exposing them.
1.42	05-Sep-2020	riastradh	branches: 1.42.6; 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. ok chs@
1.41	23-May-2020	ad	Move proc_lock into the data segment. It was dynamically allocated because at the time we had mutex_obj_alloc() but not __cacheline_aligned.
1.40	20-May-2020	christos	fix accessx confusion (thanks hannken@)
1.39	16-May-2020	christos	Add ACL support for FFS. From FreeBSD.
1.38	23-Apr-2020	ad	PR kern/54759 (vm.ubc_direct deadlock when read()/write() into mapping of itself) - Add new flag UBC_ISMAPPED which tells ubc_uiomove() the object is mmap()ed somewhere. Use it to decide whether to do direct-mapped copy, rather than poking around directly in the vnode in ubc_uiomove(), which is ugly and doesn't work for tmpfs. It would be nicer to contain all this in UVM but the filesystem provides the needed locking here (VV_MAPPED) and to reinvent that would suck more. - Rename UBC_UNMAP_FLAG() to UBC_VNODE_FLAGS(). Pass in UBC_ISMAPPED where appropriate.
1.37	04-Apr-2020	ad	branches: 1.37.2; Merge the remaining changes from the ad-namecache branch, affecting namei() and getcwd(): - push vnode locking back as far as possible. - do most lookups directly in the namecache, avoiding vnode locks & refs. - don't block new refs to vnodes across VOP_INACTIVE(). - get shared locks for VOP_LOOKUP() if the file system supports it. - correct lock types for VOP_ACCESS() / VOP_GETATTR() in a few places. Possible future enhancements: - make the lookups lockless. - support dotdot lookups by being lockless and inferring absence of chroot. - maybe make it work for layered file systems. - avoid vnode references at the root & cwd.
1.36	23-Feb-2020	ad	UVM locking changes, proposed on tech-kern: - Change the lock on uvm_object, vm_amap and vm_anon to be a RW lock. - Break v_interlock and vmobjlock apart. v_interlock remains a mutex. - Do partial PV list locking in the x86 pmap. Others to follow later.
1.35	17-Jan-2020	ad	VFS_VGET(), VFS_ROOT(), VFS_FHTOVP(): give them a "int lktype" argument, to allow us to get shared locks (or no lock) on the returned vnode. Matches FreeBSD.
1.34	17-Jun-2019	ryoon	branches: 1.34.4; Fix build without DIAGNOSTIC
1.33	26-May-2017	riastradh	branches: 1.33.10; Make VOP_RECLAIM do the last unlock of the vnode. VOP_RECLAIM naturally has exclusive access to the vnode, so having it locked on entry is not strictly necessary -- but it means if there are any final operations that must be done on the vnode, such as ffs_update, requiring exclusive access to it, we can now kassert that the vnode is locked in those operations. We can't just have the caller release the last lock because some file systems don't use genfs_lock, and require the vnode to remain valid for VOP_UNLOCK to work, notably unionfs.
1.32	26-Apr-2017	riastradh	Change VOP_REMOVE and VOP_RMDIR to preserve lock/ref on dvp. No change to vp -- the plan is to replace the node by the componentname in the vop parameters, and let all directory vops do lookups internally. Proposed on tech-kern with no objections: https://mail-index.netbsd.org/tech-kern/2017/04/17/msg021825.html
1.31	11-Apr-2017	riastradh	Make VOP_INACTIVE preserve vnode lock on return. Discussed on tech-kern: https://mail-index.netbsd.org/tech-kern/2017/04/01/msg021751.html Ride 7.99.68, a bumpy bus of incremental vfs improvements!

1.28	20-Apr-2015	riastradh	branches: 1.28.2; Make VOP_LINK return directory still locked and referenced. Ride 7.99.10 bump.
1.27	28-Mar-2015	maxv	Remove the 'cred' argument from bread(). Remove a now unused var in ffs_snapshot.c. Update the man page accordingly. ok hannken@
1.26	28-Mar-2015	maxv	Remove the 'cred' argument from breadn(), and update the man page accordingly. ok hannken@
1.25	27-Mar-2015	riastradh	Disentangle buffer-cached I/O from page-cached I/O in UFS. Page-cached I/O is used for regular files, and is initiated by VFS users such as userland and NFS. Buffer-cached I/O is used for directories and symlinks, and is issued only internally by UFS. New UFS routine ufs_bufio replaces vn_rdwr for internal use. ufs_bufio is implemented by new UFS operations uo_bufrd/uo_bufwr, which sit in ufs_readwrite.c alongside the VOP_READ/VOP_WRITE implementations. I preserved the code as much as possible and will leave further simplification for future commits. I kept the ulfs_readwrite.c copypasta close to ufs_readwrite.c in case we ever want to merge them back; likewise ext2fs_readwrite.c. No externally visible semantic change. All atf fs tests still pass.
1.24	11-Jan-2015	hannken	Change chfs from hashlist to vcache.
1.23	11-Jan-2015	hannken	Return immediately from successfull cache_lookup(). No need to unlock an unlocked vnode.
1.22	25-Jul-2014	dholland	branches: 1.22.4; Add VOP_FALLOCATE and VOP_FDISCARD to every vnode ops table I can find. The filesystem ones all call genfs_eopnotsupp - right now I am only implementing the plumbing and we can implement fallocate and/or fdiscard for files later. The device ones call spec_fallocate (which is also genfs_eopnotsupp) and spec_fdiscard, which dispatches to the device-level op. The fifo ones all call vn_fifo_bypass, which also ends up being EOPNOTSUPP.
1.21	07-Feb-2014	hannken	branches: 1.21.2; Change vnode operation lookup to return the resulting vnode *vpp unlocked. Change cache_lookup() to return an unlocked vnode. Discussed on tech-kern@ Welcome to 6.99.31
1.20	23-Jan-2014	hannken	Change vnode operations create, mknod, mkdir and symlink to return the resulting vnode *vpp unlocked. Discussed on tech-kern@ Welcome to 6.99.30
1.19	17-Jan-2014	hannken	Change vnode operations create, mknod, mkdir and symlink to keep the directory node dvp locked on return. Discussed on tech-kern@ Welcome to 6.99.29
1.18	20-Oct-2013	christos	remove unused
1.17	23-Jun-2013	dholland	branches: 1.17.2; Stick ffs_, ext2_, chfs_, filecore_, cd9660_, or mfs_ in front of the following symbols so as to disambiguate fully. (Christos already did the lfs ones.) lblkno lblktosize lfragtosize numfrags blkroundup fragroundup
1.16	19-Jun-2013	dholland	blkoff -> chfs_blkoff blksize -> chfs_blksize
1.15	18-Mar-2013	plunky	C99 section 6.7.2.3 (Tags) Note 3 states that: A type specifier of the form enum identifier without an enumerator list shall only appear after the type it specifies is complete. which means that we cannot pass an "enum vtype" argument to kauth_access_action() without fully specifying the type first. Unfortunately there is a complicated include file loop which makes that difficult, so convert this minimal function into a macro (and capitalize it). (ok elad@)
1.14	22-Jan-2013	dholland	Stuff UFS_ in front of a few of ufs's symbols to reduce namespace pollution. Specifically: ROOTINO -> UFS_ROOTINO WINO -> UFS_WINO NXADDR -> UFS_NXADDR NDADDR -> UFS_NDADDR NIADDR -> UFS_NIADDR MAXSYMLINKLEN -> UFS_MAXSYMLINKLEN MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency) Sort out ext2fs's misuse of NDADDR and NIADDR; fortunately, these have the same values in ext2fs and ffs. No functional change intended.
1.13	05-Nov-2012	dholland	Excise struct componentname from the namecache. This uglifies the interface, because several operations need to be passed the namei flags and cache_lookup also needs for the time being to be passed cnp->cn_nameiop. Nonetheless, it's a net benefit. The glop should be able to go away eventually but requires structural cleanup elsewhere first. This change requires a kernel bump.
1.12	05-Nov-2012	dholland	Disentangle the namecache from the internals of namei. - Move the namecache's hash computation to inside the namecache code, instead of being spread out all over the place. Remove cn_hash from struct componentname and delete all uses of it. - It is no longer necessary (if it ever was) for cache_lookup and cache_lookup_raw to clear MAKEENTRY from cnp->cn_flags for the cases that cache_enter already checks for. - Rearrange the interface of cache_lookup (and cache_lookup_raw) to make it somewhat simpler, to exclude certain nonexistent error conditions, and (most importantly) to make it not require write access to cnp->cn_flags. This change requires a kernel bump.
