christos 42a255dd25 Unfortunately, we need to allocate space here. Pointed out by Juan RP. 2004-05-22 23:17:04 +00:00
jonathan 230fb9b8ab Eliminate several uses of `curproc' from the socket-layer code and from NFS.
Add a new explicit `struct proc *p' argument to socreate(), sosend().
Use that argument instead of curproc. Follow-on changes to pass that
argument to socreate(), sosend(), and (*so->so_send)() calls.
These changes reviewed and independently recoded  by Matt Thomas.

Changes to soreceive() and (*dom->dom_exernalize() from Matt Thomas:
pass soreceive()'s struct uio* uio->uio_procp to unp_externalize().
Eliminate curproc from unp_externalize.   Also, now soreceive() uses
its uio->uio_procp value, pass that same value downward to
((pr->pru_usrreq)() calls for consistency, instead of (struct proc * )0.

Similar changes in sys/nfs to eliminate (most) uses of curproc,
either via the req-> r_procp field of a struct nfsreq *req argument,
or by passing down new explicit struct proc * arguments.

Reviewed by: Matt Thomas, posted to tech-kern.
NB: The (*pr->pru_usrreq)() change should be tested on more (all!) protocols.

atatat 10a7ba9ef6 Tweak sysctl setup functions (the macros, actually) for use in lkms,
and tweak lkminit_*.c (where applicable) to call them, and to call
sysctl_teardown() when being unloaded.

This consists of (1) making setup functions not be static when being
compiled as lkms (change to sys/sysctl.h), (2) making prototypes
visible for the various setup functions in header files (changes to
various header files), and (3) making simple "load" and "unload"
functions in the actual lkminit stuff.

linux_sysctl.c also needs its root exposed (ie, made not static) for
this (when built as an lkm).

christos 999e9cef64 Simplify the code by:
1. Checking for a negative uio_offset at the beginning. This really does
   not affect us in most cases because we check that later too.
2. Checking for attempts to write to init sooner and in all cases.

cl 719c5983ec Workaround for gcc 2.95.3 failing to initialize structures
and/or unions inside structures using nested designators.
Should be reverted when gcc >=3.3.3 is ready for vax.

jrf 5f626331c1 caddr_t -> void * and removal of some more casts. 2004-05-12 02:07:37 +00:00
cl 65569a4d16 Allow additional entries (files, subdirs) in kernfs. Also allow
defining additional kfstypes and provide hooks to run arbitrary code
for any vnodeop on the additional types.
2004-05-07 15:33:17 +00:00
cl a2a2784bfd remove code no longer needed since the type/permission information
is available in the entry's struct kern_target and every entry has a
(possibly shared) struct kern_target now.
2004-05-07 15:20:29 +00:00
cl 81d3c2061c Make lookup and readdir return the same inode number. kernfs_readdir
now uses kernfs_allocvp to map from kernfs entry to inode number,
kernfs_allocvp is now the only place where entries are mapped to inode
numbers.  Also make KERNFS_FILENO not return random results for entries
not in kern_targets.
2004-05-07 15:06:15 +00:00
cl 5f113f8e16 Find the right entry when doing lookup on dotdot in kern/ipsec subdirs.
Also remove some duplicate code.

jrf bafcaa70cd Removed remaining caddr_t casts we do not need in miscfs. Recompiled
kernel and ran for a day or so. There are still some caddr_t types in
the arguments of some calls, I will do those separately (later) as
they touch a lot more of the system.
Approved by christos@NetBSD.org.

jrf fc97fd571a First pass for some caddr_t removal and changes to get rid of it where we
no longer use and/or need it

	- removed casts from unionfs, deadfs and fdesc
	  (there are more to hunt down still)
	- changed vfs_quotactl args argumet from caddr_t to void *
	- changed vfs_quotactl structures/callers to reflect the api change

Compiled fine and ran for about a day. Approved/reviewed by
christos@netbsd.org and gimpy@netbsd.org.

wrstuden 8383006f0f Handle the case of fifo_close() getting called from vclean(). In that
case, we tear down the node-specific storage as if there were no more open
users. As vclean() will VT_NON the vnode before anyone else will get access
to the vnode, this is our last chance.

Fixes memory leak in revoke(2) path noticed by tedu at openbsd dot org.

hannken 142e9d5deb Add a generic copy-on-write hook to add/remove functions that will be
called with every buffer written through spec_strategy().

Used by fss(4). Future file-system-internal snapshots will need them too.

hannken 3db4e2acd8 Make VOP_STRATEGY(bp) a real VOP as discussed on tech-kern.
VOP_STRATEGY(bp) is replaced by one of two new functions:

- VOP_STRATEGY(vp, bp)  Call the strategy routine of vp for bp.
- DEV_STRATEGY(bp)      Call the d_strategy routine of bp->b_dev for bp.

DEV_STRATEGY(bp) is used only for block-to-block device situations.

atatat 13f8d2ce5f Dynamic sysctl.
Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(),
vfs_sysctl(), etc, routines, along with sysctl_int() et al.  Now all
nodes are registered with the tree, and nodes can be added (or
removed) easily, and I/O to and from the tree is handled generically.

Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded.  Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.

All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.

PS - I'm sorry, but there's a distinct lack of documentation at the
moment.  I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.

matt 7bf0959ab7 Restore a change that made AF_LOCAL sockets block on connect(2) until
accepted.  However, this time this behavor is not the default.  Instead
it must enabled by using the LOCAL_CONNWAIT socket option on either the
connecting or accepting socket.

dsl 618165063e When closing a process's controlling terminal, also remove the links
to the session and pgrp from the tty.  The way that the console is
handled means that the vrele() may not actually do the final close
on the tty itself.

hannken a3a898ff0f Add the gating of system calls that cause modifications to the underlying
file system.
The function vfs_write_suspend stops all new write operations to a file
system, allows any file system modifying system calls already in progress
to complete, then sync's the file system to disk and returns. The
function vfs_write_resume allows the suspended write operations to
complete.

From FreeBSD with slight modifications.

dsl b03412ca14 Set vnode size of character disk devices to that of the partition when they
are opened (was always done for block devices).
This means that fstat will report the partition size and hence newfs
needn't grovel into the disklabel to find the filesystem size.

mycroft 88dd794c62 Put pfsnode in the #ifdef _KERNEL too, so this actually compiles. 2003-09-27 15:32:50 +00:00
darcy 566d30be44 Changes as discussed with itojun on tech-kern. I have modified the enums
to have KFS or PFS differentiators.  Further I have wrapped the enum in
procfs in "#ifdef _KERNEL" as it is done in kernfs.

To see the discussion go to http://mail-index.NetBSD.org/tech-kern/2003/09/
and look for "Mismatched enums in include files" in the list.

yamt 61d5d4362b fix a bug of lfs.
genfs_getpages() can read in more blocks than it should due to faked filesize
of lfs_gop_size().  it's a security problem and it makes gcc3 "internal error"

to fix this,
- in genfs_getpages(), always calculate diskeof and memeof separately
  so that filesystems (in this case, lfs) can use different strategies
  for them.
- introduce GOP_SIZE_MEM flag and use it to request in-core filesize.
  (it was an intention of GOP_SIZE_READ,
  but after the above change _READ is not a straightforward name)

after this, no one uses GOP_SIZE_{READ,WRITE} anymore but leave them for now.
