* MFC: r202903Marius Strobl2010-01-312-10/+17
| | | | | | | | | | | | On LP64 struct ifid is 64-bit aligned while struct fid is 32-bit aligned so on architectures with strict alignment requirements we can't just simply cast the latter to the former but need to copy it bytewise instead.

* MFC 189696,189697:John Baldwin2010-01-212-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | Add a new internal mount flag (MNTK_EXTENDED_SHARED) to indicate that a filesystem supports additional operations using shared vnode locks. Currently this is used to enable shared locks for open() and close() of read-only file descriptors. - When an ISOPEN namei() request is performed with LOCKSHARED, use a shared vnode lock for the leaf vnode only if the mount point has the extended shared flag set. - Set LOCKSHARED in vn_open_cred() for requests that specify O_RDONLY but not O_CREAT. - Use a shared vnode lock around VOP_CLOSE() if the file was opened with O_RDONLY and the mountpoint has the extended shared flag set. - Adjust md(4) to upgrade the vnode lock on the vnode it gets back from vn_open() since it now may only have a shared vnode lock. - Don't enable shared vnode locks on FIFO vnodes in ZFS and UFS since FIFO's require exclusive vnode locks for their open() and close() routines. (My recent MPSAFE patches for UDF and cd9660 already included this change.) - Enable extended shared operations on UFS, cd9660, and UDF. Notes: svn path=/stable/7/; revision=202750

| | | | | | | | | | | Add a new type of VM object: OBJT_SG. An OBJT_SG object is very similar to a device pager (OBJT_DEVICE) object in that it uses fictitious pages to provide aliases to other memory addresses. The primary difference is that it uses an sglist(9) to determine the physical addresses for a given offset into the object instead of invoking the d_mmap() method in a device driver.

This bring huge amount of changes, I'll enumerate only user-visible changes: - Delegated Administration Allows regular users to perform ZFS operations, like file system creation, snapshot creation, etc. - L2ARC Level 2 cache for ZFS - allows to use additional disks for cache. Huge performance improvements mostly for random read of mostly static content. - slog Allow to use additional disks for ZFS Intent Log to speed up operations like fsync(2). - vfs.zfs.super_owner Allows regular users to perform privileged operations on files stored on ZFS file systems owned by him. Very careful with this one. - chflags(2) Not all the flags are supported. This still needs work. - ZFSBoot Support to boot off of ZFS pool. Not finished, AFAIK. Submitted by: dfr - Snapshot properties - New failure modes Before if write requested failed, system paniced. Now one can select from one of three failure modes: Before if write requested failed, system paniced. Now one can select from one of three failure modes: - panic - panic on write error - wait - wait for disk to reappear - continue - serve read requests if possible, block write requests - Refquota, refreservation properties Just quota and reservation properties, but don't count space consumed by children file systems, clones and snapshots. - Sparse volumes ZVOLs that don't reserve space in the pool. - External attributes Compatible with extattr(2). - NFSv4-ACLs Not sure about the status, might not be complete yet.

| | | | | | | | | | | | | The kernel may do unbalanced calls to fifo_close() for fifo vnode, without corresponding number of fifo_open(). This causes assertion failure in fifo_close() due to vp->v_fifoinfo being NULL for kernel with INVARIANTS, or NULL pointer dereference otherwise.

| | | | | | | | | | | | | | | | | After the pfs_vncache_mutex is dropped, another thread may attempt to do pfs_vncache_alloc() for the same pfs_node and pid. In this case, we could end up with two vnodes for the pair. Recheck the cache under the locked pfs_vncache_mutex after all sleeping operations are done. Do not call free() on the struct pfs_vdata after insmntque() failure, because vp->v_data points to the structure, and pseudofs_reclaim() frees it by the call to pfs_vncache_free().
