At lookup completion, we would then create a leaked node. Enter the PUFFS reclaim2 operation, which features a nlookup argument. That let us count how many lookups are pending and avoid the above described scenario. It also makes the codes simplier. - Fix directory filehandle usage with libufse. Fix lookup count libfuse does not use filehandle the same way for directories and other objects. As a result, filehandles obtained by OPENDIR should not be sent on non-directory related operations like READ/WRITE/GETATTR... While there, fix the lookup count sent to the FORGET operation, which led to leaked nodes.

New sentence, new line. Bump date for previous. Add PUFFS_KFLAG_NOFLUSH_META to prevent sending metadata flush to FUSE FUSE filesystems do not expect to get metadata updates for [amc]time and size, they updates the value on their own after operations. The PUFFS PUFFS_KFLAG_NOFLUSH_META option prevents regular metadata cache flushes to the filesystem , and libperfuse uses it to match Linux FUSE behavior. While there, fix a bug in SETATTR: do not update kernel metadata cache from SETATTR reply when the request is asynchronous, as we do not have the reply yet. Update file size after write without metadata flush If we do not use metadata flush, we must make sure the size is updated in the filesystem after a write, otherwise the next GETATTR will get us a stale value and the file will be truncated.

This produced a different cookie for the same file if it was renamed, when looking up ../ or when dealing with multiple files associated with the same name through link(2). We therefore abandon the use of node name and introduce hashed lists of inodes. This causes a huge rewrite of reclaim code, which do not attempt to keep parents allocated until all their children are reclaimed - Fix race conditions in reclaim There are a few situations where we issue multiple FUSE operations for a PUFFS operation. On reclaim, we therefore have to wait for all FUSE operation to complete, not just the current exchanges. We do this by introducing node reference count with node_ref() and node_rele(). - Detect data loss caused by FAF VOP_PUTPAGES causes FAF writes where the kernel does not check the operation result. At least issue a warning on error. - Enjoy FAF shortcut on setattr No need to wait for the result if the kernel does not want it. There is however an exception for setattr that touch the size, we need to wait for completion because we have other operations queued for after the resize. - Fix fchmod() on write-open file fchmod() on a node open with write privilege will send setattr with both mode and size set. This confuses some FUSE filesystem. Therefore we send two FUSE operations, one for mode, and one for size. - Remove node TTL handling for netbsd-5 for simplicity sake. The code still builds on netbsd-5 but does not have the node TTL feature anymore. It works fine with kernel support on netbsd-6. - Improve PUFFS_KFLAG_CACHE_FS_TTL by reclaiming older inactive nodes. The normal kernel behavior is to retain inactive nodes in the freelist until it runs out of vnodes. This has some merit for local filesystems, where the cost of an allocation is about the same as the cost of a lookup. But that situation is not true for distributed filesystems. On the other hand, keeping inactive nodes for a long time hold memory in the file server process, and when the kernel runs out of vnodes, it produce reclaim avalanches that increase lattency for other operations. We do not reclaim inactive vnodes immediatly either, as they may be looked up again shortly. Instead we introduce a grace time and we reclaim nodes that have been inactive beyond the grace time. - Fix lookup/reclaim race condition. The above improvement undercovered a race condition between lookup and reclaim. If we reclaimed a vnode associated with a userland cookie while a lookup returning that same cookiewas inprogress, then the kernel ends up with a vnode associated with a cookie that has been reclaimed in userland. Next operation on the cookie will crash (or at least confuse) the filesystem. We fix this by introducing a lookup count in kernel and userland. On reclaim, the kernel sends the count, which enable userland to detect situation where it initiated a lookup that is not completed in kernel. In such a situation, the reclaim must be ignored, as the node is about to be looked up again. Fix hang unmount bug introduced by last commit. We introduced a slow queue for delayed reclaims, while the existing queue for unmount, flush and exist has been renamed fast queue. Both queues had timestamp for when an operation should be done, but it was useless for the fast queue, which is always used to run an operation ASAP. And the timestamp test had an error that turned ASAP into "at next tick", but nobody what there to wake the thread at next tick, hence the hang. The fix is to remove the useless and buggy timestamp test for fast queue. Rename slow sopreq queue into node sopreq queue, to refet the fact that is only intended for postponed node reclaims. When purging the node sopreq queue, do not call puffs_msg_sendresp(), as it makes no sense. Fix race condition between (create|mknod|mkdir|symlino) and reclaim, just like we did it between lookup and reclaim. Missing bit in previous commit (prevent race between create|mknod|mkdir|symlink and reclaim) Bump date for previous. New sentence, new line; remove trailing whitespace; fix typos; punctuation nits. Add PUFFS_KFLAG_CACHE_DOTDOT so that vnodes hold a reference on their parent, keeping them active, and allowing to lookup .. without sending a request to the filesystem. Enable the featuure for perfused, as this is how FUSE works. Missing bit in previous commit (PUFFS_KFLAG_CACHE_DOTDOT option to avoid looking up ..)

Set buffer size as big in nomal mode as we do in debug mode, when perfused stays in foreground. The difference is a mistake and was not intended. There is still a bug ready to bite here, since SOCK_STREAM is not reliable. We just hope that buffers are big enough to hold all packets, but if they are overflown, we loose a packet and a file operation gets stuck. We really nee SOCk_SEQPACKET here, but unfortunately it is very broken at that time.

- Implement proper unprivilegied user permission verifications Verification is now done in the lookup method, as it is the way to go. Of course there are corner cases, such as the sticky bit which need special handling in the remove method. - Set full fsidx in vftstat method - Do not pass O_APPEND to the filesystem. FUSE always sends the write offset, so setting O_APPEND is useless. If the filesystem uses it in an open(2) system call, it will even cause file corruptions, since offsets given to pwrite(2) will be ignored. This fix allows glusterfs to host a NetBSD ./build.sh -o build - Do not use the FUSE access method, use getattr and check for permission on our own. The problem is that a FUSE filesystem will typically use the Linux-specific setfsuid() to perform access control. If that is missing, any chack is likely to occur on behalf of the user running the filesystem (typically root), causing access method to return wrong information. - When possible, avoid performing a getattr method call and use cached value in puffs_node instead. We still retreive the latest value by calling getattr when performing append write operation, to minimize the chances that another writer appended since the last time we did. - Update puffs_node cached file size in write method - Remove unused argument to perfuse_destroy_pn()

- Correctly handle rename whith overwritten destination - Keep track of file name to avoid lookups when we can. This makes sure we do not have two cookies for the same inode, a situation that cause wreak havoc when we come to remove or rename a node. - Do not use PUFFS_FLAG_BUILDPATH at all, since we now track file names - In open, queue requests after checking for access, as there is no merit to queue a will-be-denied request while we can deny it immediatly - request reclaim of removed nodes at inactive stage

= Open files = - Restore open on our own in fsycn and readdir, as the node may not already be open, and FUSE really wants it to be. No need to close immediatly, it can be done at inactive time. = Write operations = - fix a nasty bug that corrupted files on write (written added twice) - Keep track of file size in order to honour PUFFS_IO_APPEND = many fixes in rename = - handler overwritten nodes correctly - wait for all operations on the node to drain before doing rename, as filesystems may not cope with operations on a moving file. - setback PUFFS_SETBACK_INACT_N1 cannot be used from rename, we therefore miss the inactive time for an overwritten node. This bounds us to give up PUFFS_KFLAG_IAONDEMAND. = Removed files = - forbid most operations on a removed node, return ENOENT - setback PUFFS_SETBACK_NOREF_N1 at inactive stage to cause removed file reclaim = Misc = - Update outdated ARGSUSED for lint - Fix a memory leak (puffs_pn_remove instead of puffs_pn_put) - Do not use PUFFS_FLAG_BUILDPATH except for debug output. It makes the lookup code much simplier.

== file close operations == - use PUFFS_KFLAG_WTCACHE to puffs_init so that all writes are immediatly send to the filesystem, and we do not have anymore write after inactive. As a consequence, we can close files at inactive stage, and there is not any concern left with files opened at create time. We also do not have anymore to open ourselves in readdir and fsync. - Fsync on close (inactive stage). That makes sure we will not need to do these operations once the file is closed (FUSE want an open file). short sircuit the request that come after the close, bu not fsinc'ing closed files, - Use PUFFS_KFLAG_IAONDEMAND to get less inactive calls == Removed nodes == - more ENOENT retunred for operations on removed node (but there are probably some still missing): getattr, ooen, setattr, fsync - set PND_REMOVE before sending the UNLINK/RMDIR operations so that we avoid races during UNLINK completion. Also set PND_REMOVED on node we overwirte in rename == Filehandle fixes == - queue open operation to avoid getting two fh for one file - set FH in getattr, if the file is open - Just requires a read FH for fsyncdir, as we always opendir in read mode. Ok, this is misleading :-) == Misc == - do not set FUSE_FATTR_ATIME_NOW in setattr, as we provide the time - short circuit nilpotent operations in setattr - add a filename diagnostic flag to dump file names

- performance improvement for read, readdir and write. Now we use SOCK_DGRAM, we can send many pages at once without hitting any bug - when creating a file, it is open for FUSE, but not for the kernel. If the kernel does not do a subsequent open, we have a leak. We fight against this by trying to close such file that the kernel left unopen for some time. - some code refactoring to make message exchange debug easier (more to come)

- Use SOCK_DGRAM instead of SOCK_STREAM, as the filesystem seems to assume datagram semantics: when using SOCK_STREAM, if perfused sends frames faster than the filesystem consumes them, it will grab multiple frames at once and discard anything beyond the first one. For now the code can work both with SOCK_DGRAM and SOCK_STREAM, but SOCK_STREAM support will probably have to be removed for the sake of readability. - Remeber to sync parent directories when moving a node - In debug output, display the requeue type (readdir, write, etc...)

- if perfused is not already started (cannot connect to /dev/fuse), FUSE filesystems will attempt to start it on their own, and will communicate using a socketpair - do not advertise NULL file handle as being valid when sending themback to the FUSE filesystem. - unmount if we cannot talk to the FUSE process anymore - set calling process gid properly - debug message cleanup

libperfuse(3) is a PUFFS relay to FUSE. In order to use it, FUSE filesystem must be patched to #include <perfuse.h> in the source files that open /dev/fuse and perform the mount(2) system call. The FUSE filesystem must be linked with -lperfuse. libperfuse(3) implements the FUSE kernel interface, on which libfuse or any FUSE filesystem that opens /dev/fuse directly can be used. For now, an external daemon called perfused(8) is used. This may change in the future.
