Re: [Xen-devel] [PATCH v5 6/8] mm: Keep heap accessible to others while scrubbing

Changes in v5:

I don't see the need for this:

+pg.u.free.val = ACCESS_ONCE(head->u.free.val);


Something like ACCESS_ONCE(head->u.free).val ought to work (or read_atomic(),
due to the questionable scalar type check in ACCESS_ONCE()).


Hmm... I couldn't get this to work with either suggestion.

page_alloc.c:751:13: error: conversion to non-scalar type requested
 pg.u.free = read_atomic(>u.free);

Would you mind explaining to me (again?) why you can't set pg's first_dirty
directly here? In case I'm not mistaken and this has been asked before, maybe
this is a hint that a comment might be warranted.



In get_free_buddy() (formerly part of alloc_heap_pages()) I have

   /* Find smallest order which can satisfy the request. */
for ( j = order; j <= MAX_ORDER; j++ )
{
if ( (pg = page_list_remove_head((node, zone, j))) )
{
if ( pg->u.free.first_dirty == INVALID_DIRTY_IDX )
return pg;
/*
 * We grab single pages (order=0) even if they are
 * unscrubbed. Given that scrubbing one page is 
fairly quick

 * it is not worth breaking higher orders.
 */
if ( (order == 0) || use_unscrubbed )
{
check_and_stop_scrub(pg);
return pg;
}


If first_dirty gets assigned INVALID_DIRTY_IDX then get_free_buddy() 
will return pg right away without telling the scrubber that the buddy 
has been taken for use. The scrubber will then put the buddy back on the 
heap.

  This new call is trying to update a requested map cache entry
  according to the changes in the physmap. The call is searching
  for the entry, unmaps it and maps again at the same place using

  xen: don't use xenstore to save/restore physmap anymore
  
  If we have a system with xenforeignmemory_map2() implemented
  we don't need to save/restore physmap on suspend/restore
  anymore. In case we resume a VM without physmap - try to
  recreate the physmap during memory region restore phase and
  remap map cache entries accordingly. The old code is left
  for compatibility reasons.

While I can see why you use it here, the softirq_pending() looks sort of
misplaced: While invoking it twice in the caller will look a little odd too,
I still think that's where the check belongs.



scrub_free_pages is called from idle loop as

else if ( !softirq_pending(cpu) && !scrub_free_pages() )
pm_idle();

so softirq_pending() is unnecessary here.

(Not sure why you are saying it would be invoked twice)

No need for !! here. But I wonder whether that part of the check is really
useful anyway, considering the sole use ...

... here. If it isn't, I think the local variable isn't warranted either.
If you agree, the thus adjusted patch can have

(otherwise I'll wait with it to understand the reason first).




first_dirty_pg is indeed unnecessary but I think local variable is 
useful to avoid ANDing memflags inside the loop on each iteration 
(unless you think compiler is smart enough to realize that memflags is 
not changing).

I kept node_need_scrub[] as a global array and not a "per-node". I think 
splitting
it should be part of making heap_lock a per-node lock, together with increasing
scrub concurrency by having more than one CPU scrub a node.


Agreed - I hadn't meant my earlier comment to necessarily affect this series.

Pointer subtraction already includes the involved division. 



Yes, this was a mistake.


Otoh I wonder
if you couldn't get away without pointer comparison/subtraction here
altogether.



Without comparison I can only assume that first_dirty is zero (i.e. the 
whole buddy is potentially dirty). Is there something else I could do?

I'm afraid I continue to be confused by this: Why does need_scrub depend on
the state of pages not being the subject of the current free operation? I
realize that at this point in the series the path can't be taken yet, but
won't later patches need to rip it out or change it anyway, in which case it

Right, at this point we indeed will never have the 'if' evaluate to true

[Xen-devel] VPMU interrupt unreliability

2017-07-22 Thread Kyle Huey

Last year I reported[0] seeing occasional instability in performance
counter values when running rr[1], which depends on completely
deterministic counts of retired conditional branches of userspace
programs.

I recently identified the cause of this problem. Xen's VPMU code
contains a workaround for an alleged Nehalem bug that was added in
2010[2]. Supposedly if a hardware performance counter reaches 0
exactly during a PMI another PMI is generated potentially causing an
endless loop. The workaround is to set the counter to 1. In 2013 the
original bug was believed to affect more than just Nehalem and the
workaround was enabled for all family 6 CPUs.[3] This workaround
unfortunately disturbs the counter value in non-deterministic ways
(since the value the counter has in the irq handler depends on
interrupt latency), which is fatal to rr.

I've verified that the discrepancies we see in the counted values are
entirely accounted for by the number of times the workaround is used
in any given run. Furthermore, patching Xen not to use this
workaround makes the discrepancies in the counts vanish. I've added
code[4] to rr that reliably detects this problem from guest userspace.

Even with the workaround removed in Xen I see some additional issues
(but not disturbed counter values) with the PMI, such as interrupts
occasionally not being delivered to the guest. I haven't done much
work to track these down, but my working theory is that interrupts
that "skid" out of the guest that requested them and into Xen itself
or perhaps even another guest are not being delivered.

Our current plan is to stop depending on the PMI during rr's recording
phase (which we use for timeslicing tracees primarily because it's
convenient) to enable producing correct recordings in Xen guests.
Accurate replay will not be possible under virtualization because of
the PMI issues; that will require transferring the recording to
another machine. But that will be sufficient to enable the use cases
we care about (e.g. record an automated process on a cloud computing
provider and have an engineer download and replay a failing recording
later to debug it).

I can think of several possible ways to fix the overcount problem, including:
1. Restricting the workaround to apply only to older CPUs and not all
family 6 Intel CPUs forever.
2. Intercepting MSR loads for counters that have the workaround
applied and giving the guest the correct counter value.
3. Or perhaps even changing the workaround to disable the PMI on that
counter until the guest acks via GLOBAL_OVF_CTRL, assuming that works
on the relevant hardware.

Since I don't have the relevant hardware to test changes to this
workaround on and rr can avoid these bugs through other means I don't
expect to work on this myself, but I wanted to apprise you of what
we've learned.

  commit 5ba3d7564593c55292056ef5af84d50b55ebcf0e
  Author: Igor Druzhinin 
  Date:   Mon Jul 10 23:40:02 2017 +0100
  
  xen/mapcache: introduce xen_replace_cache_entry()
  
  This new call is trying to update a requested map cache entry
  according to the changes in the physmap. The call is searching
  for the entry, unmaps it and maps again at the same place using
  a new guest address. If the mapping is dummy this call will
  make it real.
  
  This function makes use of a new xenforeignmemory_map2() call
  with an extended interface that was recently introduced in
  libxenforeignmemory [1].

Hmm, okay. I estimated the risk of adding this new driver to be rather
low, as it won't be used other than in development systems right now.

In case you don't want to pull it I'm fine with sending you another
pull request without this driver.

  commit 04bf2526ce87f21b32c9acba1c5518708c243ad0
  Author: Prasad J Pandit 
  Date:   Wed Jul 12 18:08:40 2017 +0530
  
  exec: use qemu_ram_ptr_length to access guest ram
  
  When accessing guest's ram block during DMA operation, use
  'qemu_ram_ptr_length' to get ram block pointer. It ensures
  that DMA operation of given length is possible; And avoids
  any OOB memory access situations.
