Hey Andy,
I just started testing linus/master and found out that I get this bootup error:
mapping kernel into physical memory
about to get started...

Using git bisect (see attached bisection log) I've narrowed it down
to this commit:
commit 9fd67b4ed0714ab718f1f9bd14c344af336a6df7
Author: Andy Lutomirski <luto@MIT.EDU>
Date: Sun Jun 5 13:50:19 2011 -0400
x86-64: Give vvars their own page
Move vvars out of the vsyscall page into their own page and mark
it NX.
Please see attached .config file
The guest config is as follow:
kernel="/home/konrad/ssd/xtt/dist/common/vmlinuz"
ramdisk="/home/konrad/ssd/xtt/dist/common/initramfs.cpio.gz"
extra="console=hvc0 debug earlyprintk=xenboot"
memory=2048
vcpus=4
name="latest"
on_crash="preserve"
vif = [ 'mac=00:0F:4B:00:00:68, bridge=switch' ]
vfb = [ 'vnc=1, vnclisten=0.0.0.0,vncunused=1']
And I am using Xen 4.1.1 hypervisor. This Wiki: http://wiki.xensource.com/xenwiki/XenParavirtOps
has details on how to compile Xen, pvops, etc.

Using git bisect (see attached bisection log) I've narrowed it down
to this commit:
commit 9fd67b4ed0714ab718f1f9bd14c344af336a6df7
Author: Andy Lutomirski <luto@MIT.EDU>
Date: Sun Jun 5 13:50:19 2011 -0400
x86-64: Give vvars their own page
Move vvars out of the vsyscall page into their own page and mark
it NX.
Please see attached .config file
The guest config is as follow:
kernel="/home/konrad/ssd/xtt/dist/common/vmlinuz"
ramdisk="/home/konrad/ssd/xtt/dist/common/initramfs.cpio.gz"
extra="console=hvc0 debug earlyprintk=xenboot"
memory=2048
vcpus=4
name="latest"
on_crash="preserve"
vif = [ 'mac=00:0F:4B:00:00:68, bridge=switch' ]
vfb = [ 'vnc=1, vnclisten=0.0.0.0,vncunused=1']
And I am using Xen 4.1.1 hypervisor. This Wiki: http://wiki.xensource.com/xenwiki/XenParavirtOps
has details on how to compile Xen, pvops, etc.

Looks sane by analogy to the other code there, but I don't know how
this stuff works in Xen. Jeremy?

That will, indeed, crash your system.
0xe033 is FLAT_RING3_CS64
Jeremy / other Xen people: I'm trying to implement a lightweight
check to distinguish a trap from a sane (i.e. allowable for syscalls)
64-bit user context from anything else. There seems to be precedent
for using ->cs == __USER_CS to detect 64-bitness; for example, step.c
contains:
#ifdef CONFIG_X86_64
case 0x40 ... 0x4f:
if (regs->cs != __USER_CS)
/* 32-bit mode: register increment */
return 0;
/* 64-bit mode: REX prefix */
continue;
#endif
The prefetch opcode checker in mm/fault.c does something similar.
Even the sysret code in xen/xen-asm_64.S does:
pushq %r11
pushq $__USER_CS
pushq %rcx
So I'm at a bit of a loss.
You could probably hack it up and get your kernel to boot by allowing
__USER_CS and 0xe033 in that check, but I'd rather understand it
before submitting a patch.

That (namely the latter) has been in place basically forever (also in
the original http://xenbits.xen.org/hg/linux-2.6.18-xen.hg/ tree),
but indeed would seem to need addition of a check against Xen's
ring-3 64-bit CS. It's just that in the pre-existing cases the
consequences are at worst moderate...

While it is possible to run on the Xen provided convenience flat
segments, is there any reason not to just switch to using the Linux
selector values as early as possible on boot?
(I expect the reason for your seg faults is that kernel also runs in
ring3 for 64 bit PV Xen, i.e. FLAT_KERNEL_CS64 == FLAT_RING3_CS64,
although I thought we ensured that the on-stack representations of the
selectors was correct for the actual privilege level (to allow for
simple checks of kernel vs non-kernel segments e.g. with seg@~3 type
constructs). The error doesn't print the CS so it's hard to tell for
sure so I'm guessing).

My best guess is that each task starts out with standard __USER_CS,
but the code in write_stack_trampoline (in the hypervisor) tells the
kernel that CS is 0xe033 and then the next return to userspace makes
it true.
I'll hack up a patch to avoid the crash. I'll feel better about it if
you or any of the Xen gurus can confirm that explanation. If I'm
right, I need to check for both __USER_CS and FLAT_RING3_CS.

Yes, that's right.

Either that, or Linux needs to poke its preferred 32- or 64-bit user CS
value into the return stackframe when it receives a syscall notification
from Xen.

But it's still weird, because AFAICT xen_sysret64 already does the
right thing. So presumably the failure case only happens when
something prevents sysret from working, like CONFIG_AUDITSYSCALL.

That sounds simpler. It will also make Xen userspace look more like
native userspace.

I lied. I still don't see what's going on.
Xen, in enlighten.c, registers xen_syscall_target as the 64-bit
syscall target (or at least I assume that's what CALLBACKTYPE_syscall
does).
xen_syscall_target does this:
.macro undo_xen_syscall
mov 0*8(%rsp), %rcx
mov 1*8(%rsp), %r11
mov 5*8(%rsp), %rsp
.endm
/* Normal 64-bit system call target */
ENTRY(xen_syscall_target)
undo_xen_syscall
jmp system_call_after_swapgs
ENDPROC(xen_syscall_target)
So the 0xe033 that Xen writes is popped back off the kernel stack and ignored.
xen_sysret64 explicitly pushes __USER_CS as its CS value, so that path looks OK.
If we go into the iret patch (via auditing, for example), then the
FIXUP_TOP_OF_STACK macro does movq $__USER_CS,CS+\offset(%rsp), which
(unless it's buggy) writes __USER_CS into the appropriate spot.
So I don't see what part of the entry path needs patching.

You'll get Xen's flat CS values loaded if Xen uses SYSRET to return to guest
context. This will happen on return to guest userspace if the guest kernel
calls the iret hypercall specifying the VGCF_in_syscall flag. And that would
typically happen when returning to userspace after a syscall. So I guess the
typical user process will quickly end up using the Xen code selector rather
than Linux's own.

The correct fix is to just look at the cpl in cs and ignore the rest of the selector.

No. All three of these code paths are trap handlers that are trying
to distinguish between 64-bit and 32-bit segments. The CPL is 3 in
either case.
It looks like the reason I didn't find the code that it references
TRAP_syscall not VCGF_in_syscall. Yay for grep-unfriendly code.
Barring a better idea, I'll implement a new paravirt op.

My current patch adds a field to pv_info. I agree it's ugly.
How terrible would it be to stop using VCGF_in_syscall so we can keep
__USER_CS? Is there a real performance advantage to VCGF_in_syscall?

I don't know. 64-bit PV guests are already pretty horrid because of all
the pagetable switching, so it may be that iret vs sysret disappears in
the wash. It's certainly a cleaner fix, but I would want to measure it
before committing to it.

On Sandy Bridge, a null vsyscall takes 373 ns. Without
VCGF_in_syscall, it's 457 ns. The change causes my little test app to
get cs == __USER_CS.
I suspect that Sandy Bridge is just about the worst case. syscall and
sysret are amazingly fast on Sandy Bridge.

Hm, 20% is more noticable than I would hope. What about a regular syscall?

VCGF_in_syscall: gettimeofday() (the syscall version) takes 593 ns.
Without VCGF_in_syscall, it's 712 ns.
I'd argue for using my original approach of adding a user_64bit_mode
function -- I think it's a legitimate cleanup and Xen, for better or
worse, really does have two long mode CPL 3 selectors. If we removed
selector 6 from the GDT, that would be a different story, but that
would probably be a more intrusive change.
