* Some times ago, vfs_getopts() was changed, so that it would set error toOlivier Houchard2007-08-201-5/+5
| | | | | | | | | | | | | | | ENOENT if the option wasn't provided, instead of setting it to 0. xfs however didn't catch up on this, so it assumed something went bad if vfs_getopts() sets the error to non-zero, and just returns the error. Unbreak xfs mount by just ignoring the error if vfs_getopts() sets the error to ENOENT, as we should have sane defaults.

* Eliminate now-unused SUSER_ALLOWJAIL arguments to priv_check_cred(); inRobert Watson2007-06-121-12/+6
| | | | | | | | | | | | | | | | | | some cases, move to priv_check() if it was an operation on a thread and no other flags were present. Eliminate caller-side jail exception checking (also now-unused); jail privilege exception code now goes solely in kern_jail.c. We can't yet eliminate suser() due to some cases in the KAME code where a privilege check is performed and then used in many different deferred paths. Do, however, move those prototypes to priv.h.

| | | | | | | | | | | | | | | | | | | | | | td_ru. This removes the requirement for per-process synchronization in statclock() and mi_switch(). This was previously supported by sched_lock which is going away. All modifications to rusage are now done in the context of the owning thread. reads proceed without locks. - Aggregate exiting threads rusage in thread_exit() such that the exiting thread's rusage is not lost. - Provide a new routine, rufetch() to fetch an aggregate of all rusage structures from all threads in a process. 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. Tick statistics are kept in the thread and protected by sched_lock until it exits.

* Optimize sx locks to use simple atomic operations for the common cases ofJohn Baldwin2007-03-312-79/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Make insmntque() externally visibile and allow it to fail (e.g. duringTor Egge2007-03-133-2/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Repair ext2fs writes.Martin Cracauer2006-04-131-1/+1
| | | | | | | | | | | | | | | | | | | Strong candidate for backport to 6.x. When allocating new blocks, the search for block group beginnings would fail with a segfault. There was a side-effect read access with an off-by-one errors. The results were not used in the error case so the code worked in the past. But now the FreeBSD kernel has tighter mappings and the word accessed is not mapped (for me). The Linux kernel has rewritten most of the allocation strategy by now. Also, the Linux kernel cleaned up the integration of these files and it look feasable to wrap the original Linux files in wrapper that provides their favorite arguments instead of dragging around our own code.
