* Change the suser() API to take advantage of td_ucred as well as do ajhb2002-04-011-2/+2
| | | | | | | | | | | | general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag.

This way we only break kld's once rather then twice. nvnodelist will eventually turn into the dirty list and should remain compatible with the klds.

* Change the second argument of vflush() to an integer that specifiesiedowse2001-05-161-2/+2
| | | | | | | | | | | | | | | | | | | | the number of references on the filesystem root vnode to be both expected and released. Many filesystems hold an extra reference on the filesystem root vnode, which must be accounted for when determining if the filesystem is busy and then released if it isn't busy. The old `skipvp' approach required individual filesystem xxx_unmount functions to re-implement much of vflush()'s logic to deal with the root vnode. All 9 filesystems that hold an extra reference on the root vnode got the logic wrong in the case of forced unmounts, so `umount -f' would always fail if there were any extra root vnode references. Fix this issue centrally in vflush(), now that we can. This commit also fixes a vnode reference leak in devfs, which could result in idle devfs filesystems that refuse to unmount.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | An initial tidyup of the mount() syscall and VFS mount code. This code replaces the earlier work done by jlemon in an attempt to make linux_mount() work. * the guts of the mount work has been moved into vfs_mount(). * move `type', `path' and `flags' from being userland variables into being kernel variables in vfs_mount(). `data' remains a pointer into userspace. * Attempt to verify the `type' and `path' strings passed to vfs_mount() aren't too long. * rework mount() and linux_mount() to take the userland parameters (besides data, as mentioned) and pass kernel variables to vfs_mount(). (linux_mount() already did this, I've just tidied it up a little more.) * remove the copyin*() stuff for `path'. `data' still requires copyin*() since its a pointer into userland. * set `mount->mnt_statf_mntonname' in vfs_mount() rather than in each filesystem. This variable is generally initialised with `path', and each filesystem can override it if they want to. * NOTE: f_mntonname is intiailised with "/" in the case of a root mount.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mtx_enter(lock, type) becomes: mtx_lock(lock) for sleep locks (MTX_DEF-initialized locks) mtx_lock_spin(lock) for spin locks (MTX_SPIN-initialized) similarily, for releasing a lock, we now have: mtx_unlock(lock) for MTX_DEF and mtx_unlock_spin(lock) for MTX_SPIN. We change the caller interface for the two different types of locks because the semantics are entirely different for each case, and this makes it explicitly clear and, at the same time, it rids us of the extra `type' argument. The enter->lock and exit->unlock change has been made with the idea that we're "locking data" and not "entering locked code" in mind. Further, remove all additional "flags" previously passed to the lock acquire/release routines with the exception of two: MTX_QUIET and MTX_NOSWITCH The functionality of these flags is preserved and they can be passed to the lock/unlock routines by calling the corresponding wrappers: mtx_{lock, unlock}_flags(lock, flag(s)) and mtx_{lock, unlock}_spin_flags(lock, flag(s)) for MTX_DEF and MTX_SPIN locks, respectively. Re-inline some lock acq/rel code; in the sleep lock case, we only inline the _obtain_lock()s in order to ensure that the inlined code fits into a cache line. In the spin lock case, we inline recursion and actually only perform a function call if we need to spin. This change has been made with the idea that we generally tend to avoid spin locks and that also the spin locks that we do have and are heavily used (i.e. sched_lock) do recurse, and therefore in an effort to reduce function call overhead for some architectures (such as alpha), we inline recursion for this case. Create a new malloc type for the witness code and retire from using the M_DEV type. The new type is called M_WITNESS and is only declared if WITNESS is enabled. Begin cleaning up some machdep/mutex.h code - specifically updated the "optimized" inlined code in alpha/mutex.h and wrote MTX_LOCK_SPIN and MTX_UNLOCK_SPIN asm macros for the i386/mutex.h as we presently need those. Finally, caught up to the interface changes in all sys code. Contributors: jake, jhb, jasone (in no particular order)
