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

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

jdolecek ed9a5a7448 use fd_getfile() in procfs_getfp(), and FILE_USE()/FILE_UNUSE() the 
returned file descriptor pointer appropriately

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

Shouldn't we introduce a PRIoff_t macro to create such format strings?

- Is it ok to convert DTYPE_PIPE to VFIFO and DTYPE_SOCKET to VSOCK?

    - Does I/O to pipes work?
    - XXX: Are there security implications?

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.

Since there are actually three struct emul's for linux, use the e_name
field to determine eligibility with strcmp().

COMPAT_LINUX is set.

sommerfeld 197579af47 Change variable used for directory offset from "int" to "off_t". 
Overkill, but avoids a host of truncation problems.
 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().

Update coda to new struct lock in struct vnode.

make fdescfs, kernfs, portalfs, and procfs actually lock their vnodes.
It's not that hard.

Make unionfs set v_vnlock = NULL so any overlayed fs will call its
VOP_LOCK.
