This will allow some file systems to choose to return a LK_SHARED locked vnode when LK_SHARED is specified for the flags argument. This patch only adds the flag.

| | | | | | | | | | | | | | | | | | | With the arrival of 128+ cores it is necessary to handle more than that. One of the first thing to change is the support for cpumask_t that needs to handle more than 32 bits masking (which happens now). Some places, however, still assume that cpumask_t is a 32 bits mask. Fix that situation by using always correctly cpumask_t when needed. While here, remove the part under STOP_NMI for the Xen support as it is broken in any case.

In some points, in particular when dealing with VOPs and functions living in the same namespace (eg. vflush) which still need to be converted, pass curthread explicitly in order to retain the old behaviour. Such loose ends will be fixed ASAP. While here fix a bug: now, UFS_EXTATTR can be compiled alone without the UFS_EXTATTR_AUTOSTART option.

* Fix two issues with bufdaemon, often causing the processes to hang inKonstantin Belousov2009-03-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the "nbufkv" sleep. First, ffs background cg group block write requests a new buffer for the shadow copy. When ffs_bufwrite() is called from the bufdaemon due to buffers shortage, requesting the buffer deadlock bufdaemon. Introduce a new flag for getnewbuf(), GB_NOWAIT_BD, to request getblk to not block while allocating the buffer, and return failure instead. Add a flag argument to the geteblk to allow to pass the flags to getblk(). Do not repeat the getnewbuf() call from geteblk if buffer allocation failed and either GB_NOWAIT_BD is specified, or geteblk() is called from bufdaemon (or its helper, see below). In ffs_bufwrite(), fall back to synchronous cg block write if shadow block allocation failed. Since r107847, buffer write assumes that vnode owning the buffer is locked. The second problem is that buffer cache may accumulate many buffers belonging to limited number of vnodes. With such workload, quite often threads that own the mentioned vnodes locks are trying to read another block from the vnodes, and, due to buffer cache exhaustion, are asking bufdaemon for help. Bufdaemon is unable to make any substantial progress because the vnodes are locked. Allow the threads owning vnode locks to help the bufdaemon by doing the flush pass over the buffer cache before getnewbuf() is going to uninterruptible sleep. Move the flushing code from buf_daemon() to new helper function buf_do_flush(), that is called from getnewbuf(). The number of buffers flushed by single call to buf_do_flush() from getnewbuf() is limited by new sysctl vfs.flushbufqtarget. Prevent recursive calls to buf_do_flush() by marking the bufdaemon and threads that temporarily help bufdaemon by TDP_BUFNEED flag.

* - Add real assertions to lockmgr locking primitives.Attilio Rao2008-02-131-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A couple of notes for this: * WITNESS support, when enabled, is only used for shared locks in order to avoid problems with the "disowned" locks * KA_HELD and KA_UNHELD only exists in the lockmgr namespace in order to assert for a generic thread (not curthread) owning or not the lock. Really, this kind of check is bogus but it seems very widespread in the consumers code. So, for the moment, we cater this untrusted behaviour, until the consumers are not fixed and the options could be removed (hopefully during 8.0-CURRENT lifecycle) * Implementing KA_HELD and KA_UNHELD (not surported natively by WITNESS) made necessary the introduction of LA_MASKASSERT which specifies the range for default lock assertion flags * About other aspects, lockmgr_assert() follows exactly what other locking primitives offer about this operation. - Build real assertions for buffer cache locks on the top of lockmgr_assert(). They can be used with the BUF_ASSERT_*(bp) paradigm. - Add checks at lock destruction time and use a cookie for verifying lock integrity at any operation. - Redefine BUF_LOCKFREE() in order to not use a direct assert but let it rely on the aforementioned destruction time check. KPI results evidently broken, so __FreeBSD_version bumping and manpage update result necessary and will be committed soon. Side note: lockmgr_assert() will be used soon in order to implement real assertions in the vnode namespace replacing the legacy and still bogus "VOP_ISLOCKED()" way.

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.

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().
