kfraser@localhost.localdomain 1df421476a Replace dom0_ops hypercall with three new hypercalls: 
1. platform_op -- used by dom0 kernel to perform actions on the
    hardware platform (e.g., MTRR access, microcode update, platform
    quirks, ...)
 2. domctl -- used by management tools to control a specified domain
 3. sysctl -- used by management tools for system-wide actions

Benefits include more sensible factoring of actions to
hypercalls. Also allows tool compatibility to be tracked separately
from the dom0 kernel. The assumption is that it will be easier to
replace libxenctrl, libxenguest and Xen as a matched set if the
dom0 kernel does not need to be replaced too (e.g., because that
would require vendor revalidation).

From here on we hope to maintain dom0 kernel compatibility. This
promise is not extended to tool compatibility beyond the existing
guarantee that compatibility will not be broken within a three-level
stable release [3.0.2, 3.0.3, etc.].

kaf24@firebug.cl.cam.ac.uk d3eb6da342 Fix a crash in gdbserver-xen where it references unmapped memory if 
the page directory / page table pages are not present (for example
through dereferencing NULL in the gdb session). Changes:

- map_domain_va_32 has been rewritten to match map_domain_va_pae and
  map_domain_va_64.

- All three functions have been extended to handle multiple vCPUs,
  (untested, but shuld work), and check for _PAGE_PRESENT.

- Keir's workaround for the compile error in map_domain_va_64 has been
  removed and hopefully fixed.

kaf24@firebug.cl.cam.ac.uk 6ca3eb3308 Fix an out-of-bounds memory access in xc_ptrace.c. 
Currently, Xen always copies the entire 512 byte extended
FPU state (fxsave) even if only the "regular" FPU state was
requested.

This breaks since the memory buffer allocated in
linux-xen-low.c:regsets_fetch_inferior_registers() is only large
enough to hold the "plain" FPU registers.

kaf24@firebug.cl.cam.ac.uk 3e3fe8486d Re-enables ptrace for paravirtualized guests. 
Changes:

- Added to_ma function which translates a physical address to a
  machine address for HVM guests and just returns the address for PV
  guests.

- Use to_ma() in map_domain_va_32, map_domain_va_pae and
  map_domain_va_64 to abstract away differences between HVM and PV
  guests.

- (From Keir, Ryan) Export CR0 to PV guests as well.

I've removed the address checks against 0 since the last version since
physical/machine address 0 should be valid. Invalid translations
should be catched in xc_map_foreign_domain.

kaf24@firebug.cl.cam.ac.uk 0b35103d54 The current ptrace code is traversing the page table structures to 
guest guest physical address, even when the guest paging is disabled.
The gdbserver-xen tries to access guest pdes & ptes to map memory of
hvm guest being debugged; and it gets a seg-fault because guest has not
setup it's paging yet. The attached patch adds guest paging state check,
so that the map_domain_va() can get the correct guest physical address
from guest va.

kaf24@firebug.cl.cam.ac.uk e265d47bd6 Consolidate xc_ptrace and xc_ptrace_core 
* xc_ptrace
  - Merge xc_ptrace_core into xc_ptrace
  - ATTACH now reads the data argument. If non-zero then
    a corefile is being debuged. Otherwise a thread has
    been attached to. This allows xc_waitdomain_core() or
    xc_waitdomain() to be called as appropriate in
    subsequent xc_ptrace() calls.
* xc_waitdomain
  - Rename xc_waitdomain (xc_ptrace.c version) __xc_waitdomain
  - Rename xc_waitdomain (xc_ptrace_core.c version) xc_waitdomain_core
  - Create xc_waitdomain (in xc_ptrace.c), a wrapper for __xc_waitdomain
    and xc_waitdomain_core.
  Consolidation seemed difficult but ctxt needs to be
  passed into xc_waitdomain_core or made global.
  Alternatively, xc_waitdomain_core could be moved into xc_ptrace.c,
  but this seems messy.
* map_domain_va
  - Rename map_domain_va (xc_ptrace_core.c version) map_domain_va_core
  - Have it accept ctxt, like xc_waitdomain_core
* myptrace and myxcwait (linux-xen-low.c)
  Removed, call the now generic xc_ptrace() and xc_waitdomain() instead

When calling xc_ptrace ATTACH, if a corefile is in use, a fd will
be passed, otherwise a pid. The fd part is important, as this
is saved internally in xc_ptrace_core.c, and passed to xc_waitdomain_core()
as neccessary. Pereviously xc_waitdomain_core() received a pid and
thus could not open the corefile.

kaf24@firebug.cl.cam.ac.uk d531f7eb39 libxc: xc_ptrace cleanups 
General Cleanups
* Use { after if consistently in xc_ptrace.c and xc_ptrace_core.c
  (But not in xc_ptrace_core() which should be removed shortly)
* Remove duplicate code and centralise around xc_ptrace.h
* Avoid ifing values covered by case in xc_ptrace()
  - PTRACE_GETREGS, PTRACE_GETFPREGS and PTRACE_GETFPXREGS are grouped into
    a single case, and then with the exception of a call to FETCH_REGS(),
    different code is executed based on ifing the values covered by the
    case.  The PTRACE_GETFPREGS and PTRACE_GETFPXREGS code is actually a
    duplicate.  This patch breaks the code out to two different cases.

Error Handling
* Eliminate FETCH_REGS macro as it forces several functions
  to have an otherwise uneeded error_out label, mittigating
  any code savins.
* Rework error handling in xc_ptrace().
  - Remove FETCH_REGS as above
  - Make sure that all dom0 errors are caught
  - Make sure errno is always set on error
* Eliminate gotos in xc_ptrace_core.c that do nothing but return

emellor@leeni.uk.xensource.com a22292f2bb Make it possible to run valgrind on code linked with the libxc libraries. 
Valgrind cannot see when a hypercall has initialised entries in a data
structure, so appropriate memsets have been placed before using dom0_op_t,
privcmd_hypercall_t, and a couple of miscellaneous blocks passed into this
layer.  This initialises the block so that valgrind considers it to be valid,
but the data therein will be immediately overwritten by the hypercall, all
being well.

These changes are semantically neutral if -DVALGRIND is not set.

Rationalise x86 CRn guest state into a ctrlreg array in the per-vcpu

gone away -- replaced by ctrlreg[3] (CR3). VCPU_guest_stts is also
gone -- it was never arch-independent anyway.

[PATCH] [PATCH] Assorted VMX patches

This patch contains the following VMX patches:

- ioemu: Update the address when doing a stosb/stosw/stosl. Without this patch
  stosb writes req->count times at the same location req->addr. Not exactly
  the intended semantics.

- xc_ptrace.c: Use the page_array to refer to partition memory. This allows
  you to use gdbserver on a VMX partition (and presumably partitions that use
  shadow page tables).

- dom0_ops.c: Preserve ECF_VMX_GUEST flag for gdbserver. Without it you
  cannot (re)set the VMX domain state.

- vmx.c: Added support for lmsw. Unmodified FreeBSD uses this when running
  inside a VMX partition.
