[PATCH 0/5] hostmem-file: Add "persistent" option

Eduardo Habkost-2
This series adds a new "persistent" option to
memory-backend-file.  The new option it will be useful if
somebody is sharing RAM contents on a file using share=on, but
don't need it to be flushed to disk when QEMU exits.

Internally, it will trigger a madvise(MADV_REMOVE) or
fallocate(FALLOC_FL_PUNCH_HOLE) call when the memory backend is
destroyed.

To make we actually trigger the new code when QEMU exits, the
first patch in the series ensures we destroy all user-created
objects when exiting QEMU.

[PATCH 1/5] vl: Clean up user-creatable objects when exiting

Eduardo Habkost-2
Delete all user-creatable objects in /objects when exiting QEMU, so they
can perform cleanup actions.

[PATCH 2/5] memory: Allow RAM up to block->max_length to be discarded

Eduardo Habkost-2
In reply to this post by Eduardo Habkost-2
Currently ram_block_discard_range() is called only by the postcopy code,
using length=block->used_length.  However, new code will use
ram_block_discard_range() to discard the contents of the entire
RAMBlock, so change the limit check to use max_length instead of
used_length.

[PATCH 3/5] memory: Add RAM_NONPERSISTENT flag

Eduardo Habkost-2
In reply to this post by Eduardo Habkost-2
The new flag will make qemu_ram_free() discard the contents of the
block.  It will be used to let QEMU be configured to avoid flushing file
contents to disk when exiting.  As MADV_REMOVE is not always supported,
the new code will try MADV_NOTNEEDED in case MADV_REMOVE fails.

The new flag will also indicate that ram_block_discard_range() can use
MADV_REMOVE when discarding memory pages.  I have considered calling
MADV_REMOVE unconditionally (as destroying the RAM contents seems to be
OK every time ram_block_discard_range() is called), but for safety I
decided to restrict the new code to blocks having RAM_NONPERSISTENT set.

Re: [PATCH 3/5] memory: Add RAM_NONPERSISTENT flag

I'd like to understand what semantics you're trying to achieve and thus
why you prefer REMOVE to DONTNEED.   If you're trying to avoid changes
being written back then doesn't a DONTNEED get rid of any changes that
have yet to be written?  Or are there changes that have already been
queued that REMOVE will kill off?

If you're just trying to save-time in writeback, it's interesting to
note my requirement is that by the time I exit this function the
process of throwing away the memory contents must be complete;
I think your requirements are a lot lazier as to when it happens.

The manpage on MADV_REMOVE is confusing; it says it doesn't work on Huge
TLB pages, but says it does work on anything that can do
FALLOC_FL_PUNCH_HOLE - which as far as I can tell hugetlbfs does.

I've got some code in my shared-postcopy world that has this function do
the following which is kind of similar:

        /* The logic here is messy;
         *    madvise DONTNEED fails for hugepages
         *    fallocate works on hugepages and shmem
         */
        need_madvise = (rb->page_size == qemu_host_page_size) &&
                       (rb->fd == -1 || !(rb->flags & RAM_SHARED));
        need_fallocate = rb->fd != -1;
        if (ret == -1 && need_fallocate) {
#ifdef CONFIG_FALLOCATE_PUNCH_HOLE
            ret = fallocate(rb->fd, FALLOC_FL_PUNCH_HOLE | FALLOC_FL_KEEP_SIZE,
                            start, length);
#endif
        }
        if (need_madvise && (!need_fallocate || (ret == 0))) {
#if defined(CONFIG_MADVISE)
            ret =  madvise(host_startaddr, length, MADV_DONTNEED);
            fprintf(stderr, "%s: Did madvise for %p got %d\n", __func__, host_startaddr, ret);
#endif
        }

Re: [PATCH 4/5] memory: Add 'persistent' parameter to memory_region_init_ram_from_file()

A little confusing having a persistent flag passed in but setting a
NONPERSISTENT flag.

One thing to watch out for is the other effect, for example I think
doing an MADV_REMOVE will zero the file;  if that's a ROM file that
would probably be bad; but your description of persistent=false
might make sense for a ROM file since it wont be changed.

Good point.  Sounds like a good idea to reword the documentation to
mentiuon that in addition to making data not written back, contents
might be destroyed.

Generally speaking, it look(ed) like REMOVE is a superset of DONTNEED:
DONTNEED will free and zero pages only on anonymous private mappings;
REMOVE will free resources and zero pages on additional cases.

One case where I can think REMOVE would be useful is tmpfs when swapping
is involved: with REMOVE, the host can drop swap contents or avoid
writing memory contents to swap even if we are using a shared tmpfs
mapping.

Other filesystems might have similar cases where unnecessary I/O
operations might be performed even after madvise(MADV_DONTNEED) is
called.  MADV_REMOVE lets us simply tell the kernel to drop the data.

I'm CCing Zack Cornelius, who initially suggested MADV_REMOVE, in case
he can describe more specific use cases.

This is a very good point.  I was assuming that REMOVE is a superset of
DONTNEED, but based on the manpage it doesn't seem to be guaranteed.
Probably I shouldn't try to reuse ram_block_discard_range() and write a
separate helper for madvise(MADV_REMOVE), as the requirements are
different.

Yes, it's confusing.  I need to do some testing to find out if HugeTLBFS
supports MADV_REMOVE today.  But my use case is just an optimization, so
it won't be a big deal if it doesn't cover every case in the first
version.

This looks safer to me.  I was bothered by the missing check for
(rb->fd != -1) in the current code.

I'm confused by the (ret == 0) check here.  Do you still want to call
madvise() if fallocate() succeeded?

Anyway, now I'm considering simply not touching
ram_block_discard_range() and adding a new helper, because the
requirements are different.  Maybe in the future we can make the two
functions share code, if we decide FALLOC_FL_PUNCH_HOLE will be useful
for RAM_NONPERSISTENT too.

(BTW, I will probably rename "persistent=no"/RAM_NONPERSISTENT to
something more explicit about data being dropped, like
"free-on-exit=yes" or "disposable=yes").

IMHO these calls are all pretty badly defined, and I think there
are a few combinations of requirements that are missing.
(For example I don't think I've found an equivalent to MADV_DONTNEED
for the case of shared hugetlbfs where you want to drop the
current pages from your mapping to cause it to repopulate from the
shared file).

Hmm now I'm confused by that check as well;  <checks notes>
if we Demorgan the right side we get:
          if (need_madvice && !(need_fallocate && (ret != 0)) {

   ie we skip the DONTNEED in the case that we wanted an fallocate but
it failed, so that we preserve the error and fail the function.

I'm not at all sure the combinations cover all the shared cases.

OK, let me know if you figure out any more of the semantics of these
functions.

In addition to the additional fixes I have planned for v2, it
looks like this series won't be enough: the memory regions will
still have a non-zero reference count when exiting QEMU.  I'm not
sure how much extra work will be required to fix that.

So, before sending a new version of this, we need to clarify one
thing: why exactly unlink()+close() wouldn't be enough to avoid
having data unnecessarily flushed to the backing store and make
the new option unnecessary?

I would expect close() to not write any data unnecessarily if
there are no remaining references to the file.  Why/when this is
not the case?

If the backend file is shared between processes, unlinking
it feels bad - you're assuming no /future/ process wants to
attach to the file. Also if QEMU aborts for any reason, the
cleanup code is never going to run

> I would expect close() to not write any data unnecessarily if

Isn't the unlink() delayed until such time as *all* open handles
on that file are closed. If so, it seems that if 2 processes
have the file open, and one closes it, it is still valid for the
kernel to want to flush data out to the backing store if it needs
to free up working memory consumed by i/o cache.

If this wasn't the case, then one process could write 20 GB of data,
unlink + close the file, and that 20 GB would never be able to be
purge from I/O cache for as long as another process had that FD
open. That would be pretty bad denial of sevice for memory management
system.

Daniel

If mem-path is a directory, QEMU will create a file, open() it
and unlink() it immediately.

This solves the problem of not running the cleanup code when QEMU
aborts (which is not solved by the madvise() method).

I'm assuming QEMU is the only process opening the file.  Are
there use cases where 1) there's a need for another process to
the keep the file open; but 2) there's no need for the data on
the file to be kept?

Saying only QEMU opens the file contradicts what is implied
by the original commit message:

AFAIK, the whole point of share=on, is so that non-QEMU processes
can open the file to get access to the guest RAM region, eg the
vhostuser backend process.  Why would you ever use share=on, if
QEMU is the only process opening the file ?

That's exactly what I'm asking about: if the use case I tried to
describe in the cover letter really makes sense.

The cover letter tried to describe a theoretical scenario where
the new flag would make a difference.  Now I'm trying to
understand why/when exactly this would happen in practice.

Zack Cornelius
The share=on attribute can also be used in the case of a pre-allocated file, created outside qemu, to be used as a memory backing, using the MAP_SHARED flag to allow data to be written out to the file in the case of host memory pressure. In this case, as the file was created outside qemu, it would also be inappropriate to unlink the file.

In Kove's specific use case, we have a file on a virtual file system, which is allocated from and backed by a hardware device. In this case, unlink isn't available, but MADV_REMOVE or FALLOC_FL_PUNCH_HOLE will prevent qemu flushing unneeded data to the backing device.
