045b6fdaf6 Make gcore(1) 64 bit safe. It was trying to parse the /proc/*/map file
using sscanf and truncating the start/end entries by writing them with a
32 bit int descriptor (%x).  The upper bytes of the 64 bit vm_offset_t
variables (for little endian machines) were uninitialized.  For big endian
machines, things would have been worse because it was storing the 32 bit
value in the upper half of the 64 bit variable.  I've changed it to use
%lx and long types.  That should work on all our platforms.

c5ac569a4b Remove a.out support from gcore(1). 2004-11-27 06:46:48 +00:00
David Schultz
6661339b82 gcore(1) apparently still cares about a.out core dumps, so it still
needs to know that a 1-page U area is part of the dump format.

e0491636b5 Use a crowbar to move the a.out code out of gcore.c and into its own
file so that we have a chance of using gcore on non-i386 platforms.  Use
linker sets to reduce the registration glue.  Remove md-sparc.c, we do not
have an a.out sparc32 port.  aoutcore.c was repocopied from gcore.c.

5e6220d9d0 * include/elf.h has been repo copied to include/elf-hints.h, and it no
longer includes machine/elf.h.
* consumers of elf.h now use the minimalist elf header possible.

This change is motivated by Binutils 2.11.0 and too much clashing over
our base elf headers and the Binutils elf headers.

1f7d250182 Change the proc information returned from the kernel so that it
no longer contains kernel specific data structures, but rather
only scalar values and structures that are already part of the
kernel/user interface, specifically rusage and rtprio. It no
longer contains proc, session, pcred, ucred, procsig, vmspace,
pstats, mtx, sigiolst, klist, callout, pasleep, or mdproc. If
any of these changed in size, ps, w, fstat, gcore, systat, and
top would all stop working. The new structure has over 200 bytes
of unassigned space for future values to be added, yet is nearly
100 bytes smaller per entry than the structure that it replaced.

c815a20cb2 Change our ELF binary branding to something more acceptable to the Binutils
maintainers.

After we established our branding method of writing upto 8 characters of
the OS name into the ELF header in the padding; the Binutils maintainers
and/or SCO (as USL) decided that instead the ELF header should grow two new
fields -- EI_OSABI and EI_ABIVERSION.  Each of these are an 8-bit unsigned
integer.  SCO has assigned official values for the EI_OSABI field.  In
addition to this, the Binutils maintainers and NetBSD decided that a better
ELF branding method was to include ABI information in a ".note" ELF
section.

With this set of changes, we will now create ELF binaries branded using
both "official" methods.  Due to the complexity of adding a section to a
binary, binaries branded with ``brandelf'' will only brand using the
EI_OSABI method.  Also due to the complexity of pulling a section out of an
ELF file vs. poking around in the ELF header, our image activator only
looks at the EI_OSABI header field.

Note that a new kernel can still properly load old binaries except for
Linux static binaries branded in our old method.

  *
  * For a short period of time, ``ld'' will also brand ELF binaries
  * using our old method.  This is so people can still use kernel.old
  * with a new world.  This support will be removed before 5.0-RELEASE,
  * and may not last anywhere upto the actual release.  My expiration
  * time for this is about 6mo.

923502ff91 useracc() the prequel:
Merge the contents (less some trivial bordering the silly comments)
of <vm/vm_prot.h> and <vm/vm_inherit.h> into <vm/vm.h>.  This puts
the #defines for the vm_inherit_t and vm_prot_t types next to their
typedefs.

This paves the road for the commit to follow shortly: change
useracc() to use VM_PROT_{READ|WRITE} rather than B_{READ|WRITE}
as argument.

2062f4ee11 Make gcore work again. It was broken by a format change in the
procfs map file when object IDs were eliminated in the mega-commit
that included procfs_map.c revision 1.19.

The map file is a terrible hodge-podge.  The fields that are used
mainly for kernel debugging should be moved out of it into a
separate file, so that the interface presented by the map file to
applications can remain stable in the face of VM system changes.

3be5f1f5ce Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

     .\"    $Id$
     .\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

it looks like there won't be time to implement gcore's ELF support
before 3.0 is released.
