jdolecek 845beacce3 add 'mounts' file for -o linux, which lists all currently mounted
filesystems; Linux glibc statvfs() uses this to get some of mount flags,
and this file is also useful as /emul/linux/etc/mtab (via symlink)

jdolecek 2993272a0c set mp->mnt_stat.f_namemax on filesystem mount, for use by statvfs 2004-09-13 19:19:44 +00:00
skrll 685703c354 Do previous slightly differently - just pass a struct lwp * and derive the
struct proc *.

OK'd by Jaromir.

hannken 8c21bc6224 Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD.
- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
    may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
    Snapshots may not be opened for writing and the attributes are read-only.
    Use the mtime as the time this snapshot was taken.
    Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
  one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
  a vnode.
- Add snapshot support to ls, fsck_ffs and dump.

Welcome to 2.0F.

atatat 53c625655c Sysctl descriptions under vfs subtree 2004-05-25 04:44:43 +00:00
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.

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.

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.

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.

fvdl d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.
2003-06-29 22:28:00 +00:00
thorpej a06b275edc Undo part of the ktrace/lwp changes. In particular:
* Remove the "lwp *" argument that was added to vget().  Turns out
  that nothing actually used it!
* Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(),
  and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted
  above, didn't use it).
* Remove all of the "lwp *" arguments to internal functions that were added
  just to appease the above.
2003-06-29 18:43:21 +00:00
darrenr 960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

jdolecek b7b5aac957 change PROCFS_FILENO() to use 5 bits for 'type', since there are more than

jdolecek f331bb3205 do not show nodes corresponding to directory descriptors for process

this fixes PR kern/21187 for good, and also avoids interesting directory

jdolecek 884bdfdbaf procfs_readdir(): in Pfd case, only show descriptors of types we want
how to represent (vnodes, fifo, pipes); also use fd_getfile() et al

this avoids annoying EOPNOTSUPP error messages from ls -F and such

christos 80ecd573c0 PR/1796: John Kohl: statfs misbehaves under chrooted environments.
- Under chroot it displays only the visible filesystems with appropriate paths.
- The statfs f_mntonname gets adjusted to contain the real path from root.
- While was there, fixed a bug in ext2fs, locking problems with vfs_getfsstat(),
  and factored out some of the vfsop statfs() code to copy_statfs_info(). This
  fixes the problem where some filesystems forgot to set fsid.
- Made coda look more like a normal fs.
