* These are Alexander Kabaev's VFSops fixes (see the thread 'Found: moduleMatthew Dillon2002-04-301-21/+82
| | | | | | | | | | | | | | | | | | | | loading breakage'). The patch fixes serious issues with the VFS operations vector array which results in a crash when a filesystem module adding a new VOP is loaded into the kernel. Basically what was happening before was that the old operations vector was being freed and a new one allocated. The original MALLOC code tended to reuse the same address for the case and so the bug did not rear its ugly head until the new memory subsystem was emplaced. This patch replaces the temporary workaround Dave O'Brien comitted in 1.58. The patch is clean enough that I intend to MFC it to stable at some point.

* Commit work-around for panics when mounting FS's that are auto-loaded asDavid E. O'Brien2002-03-251-0/+2
| | | | | | | | | | | | | | | | | | modules (ie. procfs.ko). When the kernel loads dynamic filesystem module, it looks for any of the VOP operations specified by the new filesystem that have not been registered already by the currently known filesystems. If any of such operations exist, vfs_add_vnops function calls vfs_opv_recalc function, which rebuilds vop_t vectors for each filesystem and sets all global pointers like ufs_vnops_p, devfs_specop_p, etc to the new values and then frees the old pointers. This behavior is bad because there might be already active vnodes whose v_op fields will be left pointing to the random garbage, leading to inevitable crash soon.

* Do not panic on an uninitialized VOP_xxx() call. This was meant as aPeter Wemm2000-09-061-2/+2
| | | | | | | | | | | | | | | | | | | | sanity check, but it is too easy to run into, eg: making an ACL syscall when no filesystems have the ACL implementation enabled. The original reason for the panic was that the VOP_ vector had not been assigned and therefor could not be passed down the stack.. and there was no point passing it down since nothing implemented it anyway. vop_defaultop entries could not pass it on because it had a zero (unknown) vector that was indistinguishable from another unknown VOP vector. Anyway, we can do something reasonable in this case, we shouldn't need to panic here as there is a reasonable recovery option (return EOPNOTSUPP and dont pass it down the stack).

| | | | | | | | | | | | | | | | | | | | | | | leaked memory on each unload and were limited to items referenced in the kernel copy of vnode_if.c. Now a kernel module is free to create it's own VOP_FOO() routines and the rest of the system will happily deal with it, including passthrough layers like union/umap/etc. Have VFS_SET() call a common vfs_modevent() handler rather than inline duplicating the common code all over the place. Have VNODEOP_SET() have the vnodeops removed at unload time (assuming a module) so that the vop_t ** vector is reclaimed. Slightly adjust the vop_t ** vectors so that calling slot 0 is a panic rather than a page fault. This could happen if VOP_something() was called without *any* handlers being present anywhere (including in vfs_default.c). slot 1 becomes the default vector for the vnodeop table.

| | | | | | | | | | | This is the bulk of the support for doing kld modules. Two linker_sets were replaced by SYSINIT()'s. VFS's and exec handlers are self registered. kld is now a superset of lkm.

* Taking the GENERIC kernel and commenting out MSDOSFS, CD9660{,_ROOT}, PROCFS,David E. O'Brien1998-10-051-2/+3
| | | | | | | | | | | | | | | | | | NFS_ROOT will produce kernel that cannot mount a UFS /. Vfs type numbers must be distinct from VFS_GENERIC (and VFS_VFSCONF, but that has the same value and should go away). The problem happens because NFS is the first vfs (in sys/conf order) so it gets type number 0 and conflicts harmfully with VFS_GENERIC which is also 0. The conflict is apparently harmless in the usual case when another vfs gets type number 0, because nfs is the only vfs that has sysctls.

* Ignore the statically configured vfs type numbers and assign vfsBruce Evans1998-09-051-10/+12
| | | | | | | | | | | | | | type numbers in vfs attach order (modulo incomplete reuse of old numbers after vfs LKMs are unloaded). This requires reinitializing the sysctl tree (or at least the vfs subtree) for vfs's that support sysctls (currently only nfs). sysctl_order() already handled reinitialization reasonably except it checked for annulled self references in the wrong place.

* VFS mega cleanup commit (x/N)Poul-Henning Kamp1997-10-161-12/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | 1. Add new file "sys/kern/vfs_default.c" where default actions for VOPs go. Implement proper defaults for ABORTOP, BWRITE, LEASE, POLL, REVOKE and STRATEGY. Various stuff spread over the entire tree belongs here. 2. Change VOP_BLKATOFF to a normal function in cd9660. 3. Kill VOP_BLKATOFF, VOP_TRUNCATE, VOP_VFREE, VOP_VALLOC. These are private interface functions between UFS and the underlying storage manager layer (FFS/LFS/MFS/EXT2FS). The functions now live in struct ufsmount instead. 4. Remove a kludge of VOP_ functions in all filesystems, that did nothing but obscure the simplicity and break the expandability. If a filesystem doesn't implement VOP_FOO, it shouldn't have an entry for it in its vnops table. The system will try to DTRT if it is not implemented. There are still some cruft left, but the bulk of it is done. 5. Fix another VCALL in vfs_cache.c (thanks Bruce!) Notes: svn path=/head/; revision=30474
