* o Restructure vaccess() so as to check for DAC permission to modify theRobert Watson2000-08-291-1/+1
| | | | | | | | | | | | | | | | | | | object before falling back on privilege. Make vaccess() accept an additional optional argument, privused, to determine whether privilege was required for vaccess() to return 0. Add commented out capability checks for reference. Rename some variables to make it more clear which modes/uids/etc are associated with the object, and which with the access mode. o Update file system use of vaccess() to pass NULL as the optional privused argument. Once additional patches are applied, suser() will no longer set ASU, so privused will permit passing of privilege information up the stack to the caller.

* Divorce "dev_t" from the "major|minor" bitmap, which is now calledPoul-Henning Kamp1999-05-111-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | udev_t in the kernel but still called dev_t in userland. Provide functions to manipulate both types: major() umajor() minor() uminor() makedev() umakedev() dev2udev() udev2dev() For now they're functions, they will become in-line functions after one of the next two steps in this process. Return major/minor/makedev to macro-hood for userland. Register a name in cdevsw[] for the "filedescriptor" driver. In the kernel the udev_t appears in places where we have the major/minor number combination, (ie: a potential device: we may not have the driver nor the device), like in inodes, vattr, cdevsw registration and so on, whereas the dev_t appears where we carry around a reference to a actual device. In the future the cdevsw and the aliased-from vnode will be hung directly from the dev_t, along with up to two softc pointers for the device driver and a few houskeeping bits. This will essentially replace the current "alias" check code (same buck, bigger bang). A little stunt has been provided to try to catch places where the wrong type is being used (dev_t vs udev_t), if you see something not working, #undef DEVT_FASCIST in kern/kern_conf.c and see if it makes a difference. If it does, please try to track it down (many hands make light work) or at least try to reproduce it as simply as possible, and describe how to do that. Without DEVT_FASCIST I belive this patch is a no-op. Stylistic/posixoid comments about the userland view of the <sys/*.h> files welcome now, from userland they now contain the end result. Next planned step: make all dev_t's refer to the same devsw[] which means convert BLK's to CHR's at the perimeter of the vnodes and other places where they enter the game (bootdev, mknod, sysctl).

* As described by the submitter:Mike Smith1998-05-062-5/+2
| | | | | | | | | | | | | | | | Reverse the VFS_VRELE patch. Reference counting of vnodes does not need to be done per-fs. I noticed this while fixing vfs layering violations. Doing reference counting in generic code is also the preference cited by John Heidemann in recent discussions with him. The implementation of alternative vnode management per-fs is still a valid requirement for some filesystems but will be revisited sometime later, most likely using a different framework.

This is initially only for file systems that implement the following ops that do a WILLRELE: vop_create, vop_whiteout, vop_mknod, vop_remove, vop_link, vop_rename, vop_mkdir, vop_rmdir, vop_symlink This is initial DNA that doesn't do anything yet. VFS_VRELE is implemented but not called. A default vfs_vrele was created for fs implementations that use the standard vnode management routines. VFS_VRELE implementations were made for the following file systems: Standard (vfs_vrele) ffs mfs nfs msdosfs devfs ext2fs Custom union umapfs Just EOPNOTSUPP fdesc procfs kernfs portal cd9660 These implementations may change as VOP changes are implemented. In the next phase, in the vop implementations calls to vrele and the vrele part of vput will be moved to the top layer vfs_vnops and made visible to all layers. vput will be replaced by unlock in these cases. Unlocking will still be done in the per fs layer but the refcount decrement will be triggered at the top because it doesn't hurt to hold a vnode reference a little longer. This will have minimal impact on the structure of the existing code. This will only be done for vnode arguments that are released by the various fs vop implementations. Wider use of VFS_VRELE will likely require restructuring of the code. Reviewed by: phk, dyson, terry et. al. Submitted by: Michael Hancock <michaelh@cet.co.jp> Notes: svn path=/head/; revision=33964

* VFS mega cleanup commit (x/N)Poul-Henning Kamp1997-10-161-78/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | 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
