yamt f8f70a5eb4 procfs_readdir: use a list macro. 2004-10-01 14:09:14 +00:00
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)
 2004-09-20 17:53:08 +00:00
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.

simonb b6abb6ab1d Remove some assigned-to but otherwise unused variables. 2003-10-30 01:58:17 +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 f331bb3205 do not show nodes corresponding to directory descriptors for process 
in fd/ subdirectory, nor allow lookup/open for the nodes
this fixes PR kern/21187 for good, and also avoids interesting directory
locking issues
 2003-04-17 20:50:46 +00:00
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
 2003-04-17 20:33:17 +00:00
jdolecek be4c900d41 procfs_lookup(): use fd_getfile() et al in Pfd case 2003-04-17 20:19:18 +00:00

jdolecek 64b598bf33 make some local arrays/variables static + const 2003-04-17 18:08:28 +00:00
jdolecek 98f212db7d use former genfs_eopnotsupp_rele() as genfs_eopnotsupp(), so that vnodes 
are vput()/vrele()d as necessary - some filesystems did use the wrong
one for some ops, and it's just safer to not take the chance

based on suggestion by Bill Studenmund

thorpej 03efee5585 * Allow machine-dependent code to specify hooks for ptrace(2) 
(__HAVE_PTRACE_MACHDEP) and procfs (__HAVE_PROCFS_MACHDEP).
  These changes will allow platforms like x86 (XMM) and PowerPC
  (AltiVec) to export extended register sets in a sane manner.

* Use __HAVE_PTRACE_MACHDEP to export x86 XMM registers (standard
  FP + SSE/SSE2) using PT_{GET,SET}XMMREGS (in the machdep
  ptrace request space).
* Use __HAVE_PROCFS_MACHDEP to export x86 XMM registers via
  /proc/N/xmmregs in procfs.

 1999-08-25 14:42:35 +00:00
sommerfeld 2e649e46d3 Fix PR8270: 
Problem turned out to be due to improper handling of reads beyond EOF:
they should just return without error with the uio unchanged, and the
caller will recognize this as a zero-byte return (EOF).

The previous fix to protect directory reads against bogus uio_offset
values returned EINVAL, which broke mount -o union, which only
union'ed in the lower directory if the upper directory cleanly
returned EOF.

While we're here, protect kernfs as well.

wrstuden 3bf14d81e9 Add support for fcntl(2) to generate VOP_FCNTL calls. Any fcntl 
call with F_FSCTL set and F_SETFL calls generate calls to a new
fileop fo_fcntl. Add genfs_fcntl() and soo_fcntl() which return 0
for F_SETFL and EOPNOTSUPP otherwise. Have all leaf filesystems
use genfs_fcntl().

FreeBSD by Sean Eric Fagan, but a bit different.  This makes the checks
in the same places as sef's FreeBSD patch, but does not hardcode the
"kmem" group into the kernel, and also does a check identical to the
(3) and (4) checks in the NetBSD ptrace(2):

	(1) it's not owned by you, or is set-id on exec (unless
	    you're root), or

	(2) it's init, which controls the security level of the
	    entire system, and the system was not compiled with
	    permanently insecure mode turned on.
