* MFC r189878:Konstantin Belousov2009-05-051-2/+2
| | | | | | | | | | | | | | | | | | Fix two issues with bufdaemon, often causing the processes to hang in the "nbufkv" sleep. Do not retry request for the new block from ffs_bufwrite() when write is done from bufdaemon and there is a buffer shortage. In getnewbuf(), help bufdaemon to flush dirty buffers owned by the vnode locked by curthread. For MFC, default value for sysctl vfs.flushbufqtarget is set to -1, disabling the helpers. The TDP_BUFNEED flag value from HEAD conflicts with TDP_UPCALLING KSE bit, so it is moved to the end of allocated bits. Notes: svn path=/stable/7/; revision=191813
* MFC r186194:Edward Tomasz Napierala2009-03-013-3/+8
| | | | | | | | | | | | | | | | | According to phk@, VOP_STRATEGY should never, _ever_, return anything other than 0. Make it so. This fixes "panic: VOP_STRATEGY failed bp=0xc320dd90 vp=0xc3b9f648", encountered when writing to an orphaned filesystem. Reason for the panic was the following assert: KASSERT(i == 0, ("VOP_STRATEGY failed bp=%p vp=%p", bp, bp->b_vp)); at vfs_bio:bufstrategy().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initialize birthtime fields in vn_stat() to prevent stat(2) from returning uninitialized birthtime. Most file systems don't initialize birthtime properly in their VOP_GETTATTR(). MFC r183212: Initialize va_flags and va_filerev properly in VOP_GETATTR(). Don't initialize va_vaflags and va_spare because they are not part of the VOP_GETATTR() API. Also don't initialize birthtime to ctime or zero. MFC rr183213: Initialize va_rdev to NODEV and va_fsid to VNOVAL before the VOP_GETATTR() call in vn_stat(). Thus if a file system doesn't initialize those fields in VOP_GETATTR() they will have a sane default value. MFC r183214: Initialize va_rdev to NODEV instead of 0 or VNOVAL in VOP_GETATTR(). NODEV is more appropriate when va_rdev doesn't have a meaningful value. MFC r183215: fdescfs, devfs, mqueuefs, nfs, portalfs, pseudofs, tmpfs and xfs initialize the vattr structure in VOP_GETATTR() with VATTR_NULL(), vattr_null() or by zeroing it. Remove these to allow preinitialization of fields work in vn_stat(). This is needed to get birthtime initialized correctly. Notes: svn path=/stable/7/; revision=187534

* MFC r178243:Konstantin Belousov2008-08-013-24/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Move the head of byte-level advisory lock list from the filesystem-specific vnode data to the struct vnode. Provide the default implementation for the vop_advlock and vop_advlockasync. Purge the locks on the vnode reclaim by using the lf_purgelocks(). The default implementation is augmented for the nfs and smbfs. In the nfs_advlock, push the Giant inside the nfs_dolock. Before the change, the vop_advlock and vop_advlockasync have taken the unlocked vnode and dereferenced the fs-private inode data, racing with with the vnode reclamation due to forced unmount. Now, the vop_getattr under the shared vnode lock is used to obtain the inode size, and later, in the lf_advlockasync, after locking the vnode interlock, the VI_DOOMED flag is checked to prevent an operation on the doomed vnode.

This routine must be used in any place requiring a rusage from a process prior to it's exit. The exited process's rusage is still available via p_ru. - Aggregate tick statistics only on demand via rufetch() or when a thread exits.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | obtaining and releasing shared and exclusive locks. The algorithms for manipulating the lock cookie are very similar to that rwlocks. This patch also adds support for exclusive locks using the same algorithm as mutexes. A new sx_init_flags() function has been added so that optional flags can be specified to alter a given locks behavior. The flags include SX_DUPOK, SX_NOWITNESS, SX_NOPROFILE, and SX_QUITE which are all identical in nature to the similar flags for mutexes. Adaptive spinning on select locks may be enabled by enabling the ADAPTIVE_SX kernel option. Only locks initialized with the SX_ADAPTIVESPIN flag via sx_init_flags() will adaptively spin. The common cases for sx_slock(), sx_sunlock(), sx_xlock(), and sx_xunlock() are now performed inline in non-debug kernels. As a result, <sys/sx.h> now requires <sys/lock.h> to be included prior to <sys/sx.h>. The new kernel option SX_NOINLINE can be used to disable the aforementioned inlining in non-debug kernels. The size of struct sx has changed, so the kernel ABI is probably greatly disturbed. MFC after: 1 month Submitted by: attilio Tested by: kris, pjd Notes: svn path=/head/; revision=168191

| | | | | | | | | | | | | | | | | | | | | | | | | | late stages of unmount). On failure, the vnode is recycled. Add insmntque1(), to allow for file system specific cleanup when recycling vnode on failure. Change getnewvnode() to no longer call insmntque(). Previously, embryonic vnodes were put onto the list of vnode belonging to a file system, which is unsafe for a file system marked MPSAFE. Change vfs_hash_insert() to no longer lock the vnode. The caller now has that responsibility. Change most file systems to lock the vnode and call insmntque() or insmntque1() after a new vnode has been sufficiently setup. Handle failed insmntque*() calls by propagating errors to callers, possibly after some file system specific cleanup.

| | | | | | | | | | | | | | | | | | | | | | | | file are after snaplock, while other ffs device buffers are before snaplock in global lock order. By itself, this could cause deadlock when bdwrite() tries to flush dirty buffers on snapshotted ffs. If, during the flush, COW activity for snapshot needs to allocate block and ffs_alloccg() selects the cylinder group that is being written by bdwrite(), then kernel would panic due to recursive buffer lock acquision. Avoid dealing with buffers in bdwrite() that are from other side of snaplock divisor in the lock order then the buffer being written. Add new BOP, bop_bdwrite(), to do dirty buffer flushing for same vnode in the bdwrite(). Default implementation, bufbdflush(), refactors the code from bdwrite(). For ffs device buffers, specialized implementation is used.
