f6370c7a84
fix a couple more bugs:
...
- in nfs_getpages(), unbusy any pages that we don't free in the error path.
- in nfs_putpages(), only call biowait() if we actually started any i/os.

Fix some possible locking errors in nfs_namei (XXX this function should die)

Instead of storing the filehandle in the mount structure, store the
...
vnode pointer. This avoids a locking problem with nfs_nget, and
can be done because we always have a reference on the root vnode
of the filesystem.

In nfs_inactive there's no need anymore for an extra refcount around
...
nfs_vinvalbuf, since it has a real lock on the vnode now, so getnewvnode
will not hijack it.

Get locking in rmdir right. Don't unlock a vnode when passing its

nfs_remove.

Do actual vnode locking for NFS.
2001-02-06 11:40:02 +00:00
5706160195
fix several bugs:
...
- in the cases where we skip over the i/o loop, increment npages by ridx
so that when the cleanup code starts processing the pgs array at index 0
it'll actually process all of the pages.
- process the PG_RELEASED flag when unbusying pages.
- add some missing MP locking.
- use MIN() and MAX() instead of min() and max() since the latter are
functions which take arguments of type "int" but we call them with
values of type "off_t", so the values could be truncated.

Make sure bp->b_proc is initialized. Should fix a deref-garbage-pointer
...
problem reported by msaitoh@netbsd.org . NOTE: These are marked XXXUBC
since the code that allocates the bufs is new with UBC, but it may be
the case that bp->b_proc needs to be intialized to curproc (it's used
in a call to nfs_sigintr()).

Extra diagnostic assertion: subtle pmap bugs can ultimately lead to trying

4e7404469d
fix several bugs:
...
- fix math when skipping writing pages that just need a commit.
- clear the needcommit stuff and PG_RDONLY flags on pages returned for
overwrite requests as well as for normal write faults.
- bail out of nfs_write() if we get an error.
- remove a bogus attempt to clean up after failed uiomove()s.
- bring over a workaround for a lock-ordering problem from the genfs code.
- add some missing MP locking.

Make sobind() take a struct proc *. It already took curproc and

passed it down to the appropriate usrreq function, and this
allows usage for contexts that need to be explicitly different
from curproc (like in the NFS code when binding to a reserved port).

in nfs_open(), initialize the write creds if we're opening for writing.

in nfs_flush(), only play games with B_NOCACHE for VREG vnodes.
...
if we do this for VBLK vnodes which are in use by softdep mounts,
brelse() will mark the buffer B_INVAL as well, which makes the
softdep code very unhappy.

Do not accept vnode type changes to an active node. This may wreak

havoc if the server erroneously uses the same filehandle for

that revision fixed doesn't apply anymore, it has been verified
not to be a problem with this change.

"ENOBUF" on socket writes isn't really fatal; we may just be too fast

Move handling of B_NEEDCOMMIT buffers to nfs_doio, so that bawrite() calls

Do away with nfs_writebp completely, it's not needed anymore.

do it in heaps.
