| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and KASSERT coverage. After this check there is only one "nasty" cast in this code but there is a KASSERT to protect against the wrong argument structure behind that cast. Un-inlining the meat of VOP_FOO() saves 35kB of text segment on a typical kernel with no change in performance. We also now run the checking and tracing on VOP's which have been layered by nullfs, umapfs, deadfs or unionfs. Add new (non-inline) VOP_FOO_AP() functions which take a "struct foo_args" argument and does everything the VOP_FOO() macros used to do with checks and debugging code. Add KASSERT to VOP_FOO_AP() check for argument type being correct. Slim down VOP_FOO() inline functions to just stuff arguments into the struct foo_args and call VOP_FOO_AP(). Put function pointer to VOP_FOO_AP() into vop_foo_desc structure and make VCALL() use it instead of the current offsetoff() hack. Retire vcall() which implemented the offsetoff() Make deadfs and unionfs use VOP_FOO_AP() calls instead of VCALL(), we know which specific call we want already. Remove unneeded arguments to VCALL() in nullfs and umapfs bypass functions. Remove unused vdesc_offset and VOFFSET(). Generally improve style/readability of the generated code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | split the conversion of the remaining three filesystems out from the root mounting changes, so in one go: cd9660: Convert to nmount. Add omount compat shims. Remove dedicated rootfs mounting code. Use vfs_mountedfrom() Rely on vfs_mount.c calling VFS_STATFS() nfs(client): Convert to nmount (the simple way, mount_nfs(8) is still necessary). Add omount compat shims. Drop COMPAT_PRELITE2 mount arg compatibility. ffs: Convert to nmount. Add omount compat shims. Remove dedicated rootfs mounting code. Use vfs_mountedfrom() Rely on vfs_mount.c calling VFS_STATFS() Remove vfs_omount() method, all filesystems are now converted. Remove MNTK_WANTRDWR, handling RO/RW conversions is a filesystem task, and they all do it now. Change rootmounting to use DEVFS trampoline: vfs_mount.c: Mount devfs on /. Devfs needs no 'from' so this is clean. symlink /dev to /. This makes it possible to lookup /dev/foo. Mount "real" root filesystem on /. Surgically move the devfs mountpoint from under the real root filesystem onto /dev in the real root filesystem. Remove now unnecessary getdiskbyname(). kern_init.c: Don't do devfs mounting and rootvnode assignment here, it was already handled by vfs_mount.c. Remove now unused bdevvp(), addaliasu() and addalias(). Put the few necessary lines in devfs where they belong. This eliminates the second-last source of bogo vnodes, leaving only the lemming-syncer. Remove rootdev variable, it doesn't give meaning in a global context and was not trustworth anyway. Correct information is provided by statfs(/). Notes: svn path=/head/; revision=138509

* Back when VOP_* was introduced, we did not have new-style structPoul-Henning Kamp2004-12-011-263/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | initializations but we did have lofty goals and big ideals. Adjust to more contemporary circumstances and gain type checking. Replace the entire vop_t frobbing thing with properly typed structures. The only casualty is that we can not add a new VOP_ method with a loadable module. History has not given us reason to belive this would ever be feasible in the the first place. Eliminate in toto VOCALL(), vop_t, VNODEOP_SET() etc. Give coda correct prototypes and function definitions for all vop_()s. Generate a bit more data from the vnode_if.src file: a struct vop_vector and protype typedefs for all vop methods. Add a new vop_bypass() and make vop_default be a pointer to another struct vop_vector. Remove a lot of vfs_init since vop_vector is ready to use from the compiler. Cast various vop_mumble() to void * with uppercase name, for instance VOP_PANIC, VOP_NULL etc. Implement VCALL() by making vdesc_offset the offsetof() the relevant function pointer in vop_vector. This is disgusting but since the code is generated by a script comparatively safe. The alternative for nullfs etc. would be much worse. Fix up all vnode method vectors to remove casts so they become typesafe. (The bulk of this is generated by scripts) Notes: svn path=/head/; revision=138290

* 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.

| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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.
