Pull up following revision(s) (requested by manu in ticket #50): lib/libperfuse/ops.c: revision 1.87 Rollback directory filehandle screening for FUSE lock operations libfuse has a different usage of filehandles for files and directories. A directory filehandle is valid only for directory operations such as OPENDIR, READDIR, RELEASEDIR, FSYNCDIR. Change of src/lib/libperfuse/ops.c 1.85-1.86 made sure filehandles of directories were only sent for that operations. However, the status of lock operations GETLK, SETLK, SETLKW was overlooked. The only FUSE filesystem I found using locks is GlusterFS, and it needs directory filehandles to be provided on lock operations, otherwise locking crashes the filesystem. Hence this change brings back filehandles for lock operations on directories.

We therefore have to lookup each directory entry to get the missing numbers. dot and double-dot are exceptions, as we already know the values. Moreover, the lookup code does not expect to get requests for dot and will abort perfused(8) when it gets some. In order to fix that, we just check for dot and double-dot special case and use the known values instead of sending a lookup.

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.

One more explicit error log, and two bug fixes 1) with recent FUSE, when lookup returns a null ino, it means ENOENT 2) odd corner case that caused a bug on dd if=test of=test conv=notrunc This caused the file to be open first ro, then rw. A logic bug in perfuse_node_open caused it to skip the second operation, whereas it should open for writing, and store the write FH without touching the read FH.

When lookup returns a node with null inode number, it means the ENOENT, with negative caching. We do not implement negative caching yet, but we honour the ENOENT.

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 ..)

Comma fixes. Remove dangling "and". Bump date for previous. - Makesure update_va does not change vnode size when it should not.

Serialize access to file size. We already have such a thing in the kernel, where it fixes race for PUFFS filesystems, but we need it again in perfused since FUSE filesystems are allowed to reorder requests. The huge issue is in the asyncrhonous SETATTR sent by fsync. It is followed by a syncrhnous FSYNC, so if the filesystem does not reorder requests, once the FSYNC returns, we are confident the SETATTR is done. But since FUSE can reorder, we need to implement sync in perfused.

ftruncate(2) cause a SETATTR with only va_size set, and some filesystems (e.g.: glusterfs) will do a custom handling in such a situation. This breaks because libpuffs folds a metadata (va_atime and va_mtime) update in each SETATTR. We try to identify SETATTR caused by ftruncate(2) and remove va_atime and va_mtime in such situation. This fixes a bug with glusterfs, where parts of a file downloaded by FTP was filled with zeros because of a ftruncate(2) sent out of order with write(2) requests. glusterfs behavior depends on the undocumented FUSE rule that ftruncate(2) will only set va_size in SETATTR.

FUSE struct dirent's off is not the offset in the buffer, it is an opaque cookie that the filesystem passes us, and that we need to send back on the next READDIR. Most filesystem just ignore the value and send the next chunk of buffer, but not all of them. Fixing this allows glusterfs distributed volume to work.

Add a flag to VOP_LISTEXTATTR(9) so that the vnode interface can tell the filesystem in which format extended attribute shall be listed. There are currently two formats: - NUL-terminated strings, used for listxattr(2), this is the default. - one byte length-pprefixed, non NUL-terminated strings, used for extattr_list_file(2), which is obtanined by setting the EXTATTR_LIST_PREFIXLEN flag to VOP_LISTEXTATTR(9) This approach avoid the need for converting the list back and forth, except in libperfuse, since FUSE uses NUL-terminated strings, and the kernel may have requested EXTATTR_LIST_PREFIXLEN.

Fix race conditions between write and getattr/setattr, which lead to inconsitencies between kernel and filesystem idea of file size during writes with IO_APPEND. At mine, this resulted in a configure script producing config.status with ": clr\n" lines stripped (not 100% reproductible, but always this specific string. That is of little interest except for my own future reference). When a write is in progress, getattr/setattr get/set the maximum size among kernel idea (grown by write) and filesystem idea (not yet grown).

- 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 set flags for CREATE - after a node is deleted, some operations should return ENOENT, some should be ignored. Fixed it for ACCESS, SETATTR and GETATTR. Other operation may also need a fix. - At reclaim time, there is no need to wait for READDIR and READ completion, since the caller will never close a file before getting readir() and read() replies. Waiting for WRITE completion is still mandatory, but we must ensure that no queued WRITE is awaiting to be scheduled. Once the queue is drained, we must check that the reclaim operation was not canceled by a new file LOOKUP. - At reclaim time, fixed a mix up between read and write fh to close - Fixed permission checks for RENAME (it tested the node itself instead of the source) - When seting file mode, only MKNOD needs the filetype (S_* fields). It is probably a bug to set it for other operations.

If we just close, fsync will come later and we will have to reopen - Add a PND_DIRTY flag to keep track of files that really need a sync. perfuse_node_fsync only calls the FUSE fsync method if there are data to push. - Add a PND_OPEN flag to keep track of open files. Checking non NULL fh is not enough, as some filesystems will always set fh to 0. - Add a sync diagnostic flag, to watch fsync and dirty flag activity. Make the fh diagnostic flag more verbose - Send the fh in setattr (it was hardcoded to 0) I am now able to build libperfuse in a glusterfs mounted filesystem. Yeah!

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.
