| * Finish (?) importing the Linux ext2fs files that our GPL'ed ext2fsBruce Evans2000-01-011-0/+135
| | | | | | | | | | | | | | | | | | | | | | | | files seem to be based on. Don't bother importing <asm-i386/string.h> just to get the Linux implementation of memscan() which is appended to our i386-bitops.h. The BSD skpc() should have been used instead of memscan().

* | Regularize the vop_stdlock'ing protocol across all the filesystemsKirk McKusick2002-10-143-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | that use it. Specifically, vop_stdlock uses the lock pointed to by vp->v_vnlock. By default, getnewvnode sets up vp->v_vnlock to reference vp->v_lock. Filesystems that wish to use the default do not need to allocate a lock at the front of their node structure (as some still did) or do a lockinit. They can simply start using vn_lock/VOP_UNLOCK. Filesystems that wish to manage their own locks, but still use the vop_stdlock functions (such as nullfs) can simply replace vp->v_vnlock with a pointer to the lock that they wish to have used for the vnode. Such filesystems are responsible for setting the vp->v_vnlock back to the default in their vop_reclaim routine (e.g., vp->v_vnlock = &vp->v_lock). In theory, this set of changes cleans up the existing filesystem lock interface and should have no function change to the existing locking scheme. Sponsored by: DARPA & NAI Labs.

Rather than just lock and unlock the vnode around the call to VOP_FSYNC(), implement rwatson's suggestion to lock the file vnode in kern_link() before calling VOP_LINK(), since the other filesystems also locked the file vnode right away in their link methods.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changed rename(2) to follow the letter of the POSIX spec. POSIX requires rename() to have no effect if its args "resolve to the same existing file". I think "file" can only reasonably be read as referring to the inode, although the rationale and "resolve" seem to say that sameness is at the level of (resolved) directory entries. ext2fs_vnops.c, ufs_vnops.c: Replaced code that gave the historical BSD behaviour of removing one link name by checks that this code is now unreachable. This fixes some races. All vnodes needed to be unlocked for the removal, and locking at another level using something like IN_RENAME was not even attempted, so it was possible for rename(x, y) to return with both x and y removed even without any unlink(2) syscalls (one process can remove x using rename(x, y) and another process can remove y using rename(y, x)).

* | In order to better support flexible and extensible access control,Robert Watson2002-08-152-7/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | make a series of modifications to the credential arguments relating to file read and write operations to cliarfy which credential is used for what: - Change fo_read() and fo_write() to accept "active_cred" instead of "cred", and change the semantics of consumers of fo_read() and fo_write() to pass the active credential of the thread requesting an operation rather than the cached file cred. The cached file cred is still available in fo_read() and fo_write() consumers via fp->f_cred. These changes largely in sys_generic.c. For each implementation of fo_read() and fo_write(), update cred usage to reflect this change and maintain current semantics: - badfo_readwrite() unchanged - kqueue_read/write() unchanged pipe_read/write() now authorize MAC using active_cred rather than td->td_ucred - soo_read/write() unchanged - vn_read/write() now authorize MAC using active_cred but VOP_READ/WRITE() with fp->f_cred Modify vn_rdwr() to accept two credential arguments instead of a single credential: active_cred and file_cred. Use active_cred for MAC authorization, and select a credential for use in VOP_READ/WRITE() based on whether file_cred is NULL or not. If file_cred is provided, authorize the VOP using that cred, otherwise the active credential, matching current semantics. Modify current vn_rdwr() consumers to pass a file_cred if used in the context of a struct file, and to always pass active_cred. When vn_rdwr() is used without a file_cred, pass NOCRED. These changes should maintain current semantics for read/write, but avoid a redundant passing of fp->f_cred, as well as making it more clear what the origin of each credential is in file descriptor read/write operations. Follow-up commits will make similar changes to other file descriptor operations, and modify the MAC framework to pass both credentials to MAC policy modules so they can implement either semantic for revocation.

* | - Replace v_flag with v_iflag and v_vflagJeff Roberson2002-08-041-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - v_vflag is protected by the vnode lock and is used when synchronization with VOP calls is needed. - v_iflag is protected by interlock and is used for dealing with vnode management issues. These flags include X/O LOCK, FREE, DOOMED, etc. - All accesses to v_iflag and v_vflag have either been locked or marked with mp_fixme's. - Many ASSERT_VOP_LOCKED calls have been added where the locking was not clear. - Many functions in vfs_subr.c were restructured to provide for stronger locking.

At this point, the former is a fairly arbitrary default value (DFTPHYS), so changing it to any reasonable value specified by the device driver is safe.

Using the minimum would break device drivers' ability to increase the active limit from DFTLPHYS up to MAXPHYS. Copied the code for this and the associated (unnecessary?) fixup of mp_iosize_max to all other filesystems that use clustering (ext2fs and msdosfs). It was completely missing.
