To do this, the ZPL must * properly lock its in-core state, create a DMU transaction, do the work, * record this work in the intent log (ZIL), commit the DMU transaction, * and wait for the intent log to commit if it is a synchronous operation. * Moreover, the vnode ops must work in both normal and log replay context. * The ordering of events is important to avoid deadlocks and references * to freed memory. The example below illustrates the following Big Rules: * * (1) A check must be made in each zfs thread for a mounted file system. * This is done avoiding races using zfs_enter(zfsvfs). * A zfs_exit(zfsvfs) is needed before all returns. Any znodes * must be checked with zfs_verify_zp(zp). Both of these macros * can return EIO from the calling function. * * (2) zrele() should always be the last thing except for zil_commit() (if * necessary) and zfs_exit(). This is for 3 reasons: First, if it's the * last reference, the vnode/znode can be freed, so the zp may point to * freed memory. Second, the last reference will call zfs_zinactive(), * which may induce a lot of work -- pushing cached pages (which acquires * range locks) and syncing out cached atime changes. Third, * zfs_zinactive() may require a new tx, which could deadlock the system * if you were already holding one. This deadlock occurs because the tx * currently being operated on prevents a txg from syncing, which * prevents the new tx from progressing, resulting in a deadlock. If you * must call zrele() within a tx, use zfs_zrele_async(). Note that iput() * is a synonym for zrele(). * * (3) All range locks must be grabbed before calling dmu_tx_assign(), * as they can span dmu_tx_assign() calls. * * (4) If ZPL locks are held, pass TXG_NOWAIT as the second argument to * dmu_tx_assign(). This is critical because we don't want to block * while holding locks. * * If no ZPL locks are held (aside from zfs_enter()), use TXG_WAIT. This * reduces lock contention and CPU usage when we must wait (note that if * throughput is constrained by the storage, nearly every transaction * must wait). * * Note, in particular, that if a lock is sometimes acquired before * the tx assigns, and sometimes after (e.g. z_lock), then failing * to use a non-blocking assign can deadlock the system. The scenario: * * Thread A has grabbed a lock before calling dmu_tx_assign(). * Thread B is in an already-assigned tx, and blocks for this lock. * Thread A calls dmu_tx_assign(TXG_WAIT) and blocks in txg_wait_open() * forever, because the previous txg can't quiesce until B's tx commits. * * If dmu_tx_assign() returns ERESTART and zfsvfs->z_assign is TXG_NOWAIT, * then drop all locks, call dmu_tx_wait(), and try again. On subsequent * calls to dmu_tx_assign(), pass TXG_NOTHROTTLE in addition to TXG_NOWAIT, * to indicate that this operation has already called dmu_tx_wait(). * This will ensure that we don't retry forever, waiting a short bit * each time. * * (5) If the operation succeeded, generate the intent log entry for it * before dropping locks. This ensures that the ordering of events * in the intent log matches the order in which they actually occurred. * During ZIL replay the zfs_log_* functions will update the sequence * number to indicate the zil transaction has replayed. * * (6) At the end of each vnode op, the DMU tx must always commit, * regardless of whether there were any errors. * * (7) After dropping all locks, invoke zil_commit(zilog, foid) * to ensure that synchronous semantics are provided when necessary. * * In general, this is how things should be ordered in each vnode op: * * zfs_enter(zfsvfs); // exit if unmounted * top: * zfs_dirent_lock(&dl, ...) // lock directory entry (may igrab()) * rw_enter(...); // grab any other locks you need * tx = dmu_tx_create(...); // get DMU tx * dmu_tx_hold_*(); // hold each object you might modify * error = dmu_tx_assign(tx, (waited ? TXG_NOTHROTTLE : 0) | TXG_NOWAIT); * if (error) { * rw_exit(...); // drop locks * zfs_dirent_unlock(dl); // unlock directory entry * zrele(...); // release held znodes * if (error == ERESTART) { * waited = B_TRUE; * dmu_tx_wait(tx); * dmu_tx_abort(tx); * goto top; * } * dmu_tx_abort(tx); // abort DMU tx * zfs_exit(zfsvfs); // finished in zfs * return (error); // really out of space * } * error = do_real_work(); // do whatever this VOP does * if (error == 0) * zfs_log_*(...); // on success, make ZIL entry * dmu_tx_commit(tx); // commit DMU tx -- error or not * rw_exit(...); // drop locks * zfs_dirent_unlock(dl); // unlock directory entry * zrele(...); // release held znodes * zil_commit(zilog, foid); // synchronous when necessary * zfs_exit(zfsvfs); // finished in zfs * return (error); // done, report error */ int zfs_open(struct inode *ip, int mode, int flag, cred_t *cr) { (void) cr; znode_t *zp = ITOZ(ip); zfsvfs_t *zfsvfs = ITOZSB(ip); int error; if ((error = zfs_enter_verify_zp(zfsvfs, zp, FTAG)) != 0) return (error); /* Honor ZFS_APPENDONLY file attribute */ if ((mode & FMODE_WRITE) && (zp->z_pflags & ZFS_APPENDONLY) && ((flag & O_APPEND) == 0)) { zfs_exit(zfsvfs, FTAG); return (SET_ERROR(EPERM)); } /* Keep a count of the synchronous opens in the znode */ if (flag & O_SYNC) atomic_inc_32(&zp->z_sync_cnt); zfs_exit(zfsvfs, FTAG); return (0); } int zfs_close(struct inode *ip, int flag, cred_t *cr) { (void) cr; znode_t *zp = ITOZ(ip); zfsvfs_t *zfsvfs = ITOZSB(ip); int error; if ((error = zfs_enter_verify_zp(zfsvfs, zp, FTAG)) != 0) return (error); /* Decrement the synchronous opens in the znode */ if (flag & O_SYNC) atomic_dec_32(&zp->z_sync_cnt); zfs_exit(zfsvfs, FTAG); return (0); } #if defined(_KERNEL) + +static int zfs_fillpage(struct inode *ip, struct page *pp); + /* * When a file is memory mapped, we must keep the IO data synchronized - * between the DMU cache and the memory mapped pages.

This has been shown to work * well for the common read(2)/write(2) case. However, mmap(2) * is problem because it relies on being tightly integrated with the * page cache. To handle this we cache mmap'ed files twice, once in * the ARC and a second time in the page cache. The code is careful * to keep both copies synchronized. * * When a file with an mmap'ed region is written to using write(2) * both the data in the ARC and existing pages in the page cache * are updated. For a read(2) data will be read first from the page * cache then the ARC if needed. Neither a write(2) or read(2) will * will ever result in new pages being added to the page cache. * * New pages are added to the page cache only via .readpage() which * is called when the vfs needs to read a page off disk to back the * virtual memory region. These pages may be modified without * notifying the ARC and will be written out periodically via * .writepage(). This will occur due to either a sync or the usual * page aging behavior. Note because a read(2) of a mmap'ed file * will always check the page cache first even when the ARC is out * of date correct data will still be returned. * * While this implementation ensures correct behavior it does have * have some drawbacks. The most obvious of which is that it * increases the required memory footprint when access mmap'ed * files. It also adds additional complexity to the code keeping * both caches synchronized. * * Longer term it may be possible to cleanly resolve this wart by * mapping page cache pages directly on to the ARC buffers. The * Linux address space operations are flexible enough to allow * selection of which pages back a particular index. The trick * would be working out the details of which subsystem is in * charge, the ARC, the page cache, or both. It may also prove * helpful to move the ARC buffers to a scatter-gather lists * rather than a vmalloc'ed region. */ static int zpl_mmap(struct file *filp, struct vm_area_struct *vma) { struct inode *ip = filp->f_mapping->host; int error; fstrans_cookie_t cookie; cookie = spl_fstrans_mark(); error = -zfs_map(ip, vma->vm_pgoff, (caddr_t *)vma->vm_start, (size_t)(vma->vm_end - vma->vm_start), vma->vm_flags); spl_fstrans_unmark(cookie); if (error) return (error); error = generic_file_mmap(filp, vma); if (error) return (error); #if !defined(HAVE_FILEMAP_RANGE_HAS_PAGE) znode_t *zp = ITOZ(ip); mutex_enter(&zp->z_lock); zp->z_is_mapped = B_TRUE; mutex_exit(&zp->z_lock); #endif return (error); } /* * Populate a page with data for the Linux page cache.
