1998-08-08Document the locking discipline a bit betterConstantine Sapuntzakis
1998-08-07Fix portal FS & PR #556Constantine Sapuntzakis
Basically, if file system consumes the slashes at the end of a component, don't require that the component is a directory.
1998-08-06Rename vop_revoke, vn_bwrite, vop_noislocked, vop_nolock, vop_nounlockConstantine Sapuntzakis
to be vop_generic_revoke, vop_generic_bwrite, vop_generic_islocked, vop_generic_lock and vop_generic_unlock. Create vop_generic_abortop and propogate change to all file systems. Fix PR/371. Get rid of locking in NULLFS (should be mostly unnecessary now except for forced unmounts).

1998-07-28For read, write, send, sendto, recv, recvfrom return EINVAL is size arg > ↵Todd C. Miller
SSIZE_MAX. For readv, writev, sendmsg, recvmsg return EINVAL if sum of the over iov_len values overflows an ssize_t. Based on what XPG 4.2 says (though XPG is not entirely consistent here). Basically since the return value is ssize_t allowing size > SSIZE_MAX is bad since people who (incorrectly mind you) check the return value for < 0 instead of == -1 will have bad things happen to them.
1998-07-28Don't assume uio_resid can go negative when detecting oflowTodd C. Miller
1998-07-28Return EINVAL when msg_iovlen or iovcnt <= 0; Make uio_resid unsigned ↵Todd C. Miller
(size_t) and don't return EINVAL if it is < 0 in sys_{read,write}. Remove check for uio_resid < 0 uiomove() now that uio_resid is unsigned and brack remaining panics with #ifdef DIAGNOSTIC. vn_rdwr() must now take a size_t * as its 9th argument so change that and clean up uses of vn_rdwr(). Fixes 549 + more
1998-07-13Part 1) of a fix to the "mount /mnt /mnt" problem.Constantine Sapuntzakis
Don't mount the file system in the kernel name space before calling VFS_MOUNT.
1998-07-13ftpd: sleep for an indeterminate amount for non-existant loginsTodd C. Miller
to simulate a crypt, like login does. Use SEEK_* not L_* and kill some 0L's used in lseek while we're there.

As permitted, make the truncated buffer be NUL terminated. make getdomainname() match.

/dev/null -- future patch will use a dead vnode of some sort) to prevent reuse (ie. new allocations) of these fd which libc makes many assumptions about; problem noted by James Youngman

1998-05-11Formerly reuse of unit numbers of detached devices was impossible, withNiklas Hallqvist
this change starred devices will search from the first allowed unit for such devices and up for free units when attaching. This means you have to rerun config(8) before yopu compile current kernels. FYI, this is a necessity when doing PCMCIA flashcard reading, otherwise you soon run out of unit numbers. I have also added a way to detach all children of a certain device, used in a new PCMCIA framework to come, so you detach all functions on a single PCMCIA card when pulling it out. A few bugs wrt starred devices fixed in the autoconfig_verbose code too. Last and least, fixed some panic messages.
