[Qemu-devel] [PATCH v6 00/12] curl: fix curl read

[Fam Zheng]

CURL library API has changed, the current curl driver is not working with
current libcurl. It may or may not have worked with old libcurl, but currently,
when testing with apache http URL, it just hangs before fetching any data.  The
problem is because the mismatch of our code and how libcurl wants to be used.
(man 3 curl_multi_socket_action, section 'TYPICAL USAGE')
 
 - Step 3. We need timer to support libcurl timeout.
 - Step 6. We'll call the right API function, replacing the deprecated.
 - Step 5, 8. Manage socket properly (take actions on socket fd that are passed
   into socket callback from libcurl)

This patch rewrites the use of API as well as the structure of internal states:

BDRVCURLState holds the pointer to curl multi interface (man 3
libcurl-multi), and 4 lists for internal states:
 - CURLState holds state for libcurl connection (man 3 libcurl-easy)
 - CURLSockInfo holds information for libcurl socket interface (man 3
   curl_multi_socket_action).
 - CURLDataCache holds the user data read from libcurl, it is in a list
   ordered by access, the used cache is moved to list head on access, so
   the tail element is freed first. BDRVCURLState.cache_quota is the
   threshold to start freeing cache.
 - CURLAIOCB holds ongoing aio information.

Changes from v5:
  05: Rename bs to s for BDRVCURLState.
  06: Use int64_t for offsets.
      Fix printf format string.
      Move introducing of use_count to 07.
  07: Drop explicit cast.
      Use int64_t for offsets.
      Use_count moved here.
  08: Remove duplicated.
      Move s->url = NULL to separate patch.
  09: Fix while(0);
  12: Added:
      curl: set s->url to NULL after free.

Changes from v4:
  11: Added:
        block/curl.c: Refuse to open the handle for writes.

Changes from v3:
  01, 06, 07: Add QLIST_INIT in qemu_open to initialize each list.
  07: Move clean up for s->acbs from later patch to here. Use qemu_aio_relase instead of g_free on acb.
      Fix use-after-free bug. [Rich]

Changes from v2:
  00: Removed previous 09, since changes are included in previous
      commits.
      previous 09: curl: release everything on curl close.
  01: Add commit message for introducing CURLSockInfo. Remove
      unnecessary pointer type cast.
  02: Use sizeof instead of macro for s->range len.
  04: Use pstrcpy and strncasecmp.
  06: Add commit message for why is there a cache in curl.c.

Changes from v1:
   Split to multiple patches. The final status should be identical to v1.

Fam Zheng (11):
  curl: introduce CURLSockInfo to BDRVCURLState.
  curl: change magic number to sizeof
  curl: change curl_multi_do to curl_fd_handler
  curl: fix curl_open
  curl: add timer to BDRVCURLState
  curl: introduce CURLDataCache
  curl: make use of CURLDataCache.
  curl: use list to store CURLState
  curl: add cache quota.
  curl: introduce ssl_no_cert runtime option.
  curl: set s->url to NULL after free.

Richard W.M. Jones (1):
  block/curl.c: Refuse to open the handle for writes.

[Qemu-devel] [PATCH v6 01/12] curl: introduce CURLSockInfo to BDRVCURLState.

[Fam Zheng]

We use socket provided by curl in the driver.  Libcurl multi interface
has option CURLMOPT_SOCKETFUNCTION for socket.

Per man 3 curl_multi_setopt:

    ...
    CURLMOPT_SOCKETFUNCTION

    Pass a pointer to a function matching the curl_socket_callback
    prototype. The curl_multi_socket_action(3) function informs the
    application about updates in the socket (file descriptor) status by
    doing none, one, or multiple calls to the curl_socket_callback given in
    the param argument. They update the status with changes since the
    previous time a curl_multi_socket(3) function was called. If the given
    callback pointer is NULL, no callback will be called. Set the callback's
    userp argument with CURLMOPT_SOCKETDATA. See curl_multi_socket(3) for
    more callback details.
    ...

The added structure store information for all the socket returned by
libcurl. The most important field is action, which is used to keep what
actions are needed when this socket's fd handler is called.

CURLSockInfo is added here and used in later commits to save the socket
actions.

[Qemu-devel] [PATCH v6 03/12] curl: change curl_multi_do to curl_fd_handler

[Fam Zheng]

The driver calls curl_multi_do to take action at several points, while
it's also registered as socket fd handler. This patch removes internal
call of curl_multi_do because they are not necessary when handler can be
called by socket data update.

Since curl_multi_do becomes a pure fd handler, the function is renamed.
It takes a pointer to CURLSockInfo now, instead of pointer to
BDRVCURLState.

[Qemu-devel] [PATCH v6 04/12] curl: fix curl_open

[Fam Zheng]

Change curl_size_cb to curl_header_cb, as what the function is really
doing. Fix the registering, CURLOPT_WRITEFUNCTION is apparently wrong,
should be CURLOPT_HEADERFUNCTION.

Parsing size from header is not necessary as we're using

  curl_easy_getinfo(state->curl, CURLINFO_CONTENT_LENGTH_DOWNLOAD, &d)

The validity of d is version dependant per man 3 curl_easy_getinfo:

    ...
    CURLINFO_CONTENT_LENGTH_DOWNLOAD

    Pass a pointer to a double to receive the content-length of the
    download. This is the value read from the Content-Length: field.
    Since 7.19.4, this returns -1 if the size isn't known.
    ...

And Accept-Ranges is essential for curl to fetch right data from
http/https servers, so we check for this in the header and fail the open
if it's not supported.

[Qemu-devel] [PATCH v6 05/12] curl: add timer to BDRVCURLState

[Fam Zheng]

libcurl uses timer to manage ongoing sockets, it needs us to supply
timer. This patch introduce QEMUTimer to BDRVCURLState and handles
timeouts as libcurl expects (curl_multi_timer_cb sets given timeout
value on the timer and curl_timer_cb calls curl_multi_socket_action on
triggered).

[Qemu-devel] [PATCH v6 06/12] curl: introduce CURLDataCache

[Fam Zheng]

Data buffer was contained by CURLState, they are allocated and freed
together. This patch try to isolate them, by introducing a dedicated
cache list to BDRVCURLState. The benifit is we can now release the
CURLState (and associated sockets) while keep the fetched data for later
use, and simplies the prefetch and buffer logic for some degree.

Note: There's already page cache in guest kernel, why cache data here?
Since we don't want to submit http/ftp/* request for every 2KB in
sequencial read, but there are crude guest that sends small IO reqs,
which will result in horrible performance.  GRUB/isolinux loading kernel
is a typical case and we workaround this by prefetch cache.  This is
what curl.c has been doing along. This patch just refectors the buffer.

[Qemu-devel] [PATCH v6 08/12] curl: use list to store CURLState

[Fam Zheng]

Make it consistent to other structures to use QLIST to store CURLState.
It also simplifies initialization and releasing of data.

[Qemu-devel] [PATCH v6 09/12] curl: add cache quota.

[Fam Zheng]

Introduce a cache quota: BDRVCURLState.cache_quota.
When adding new CURLDataCache to BDRVCURLState, if number of existing
CURLDataCache is larger than CURL_CACHE_QUOTA, try to release some first
to limit the in memory cache size.

A least used entry is selected for releasing.

Rich, are you testing with libguestfs or qemu? Since I can't get
libguestfs run with your patch to refuse writable open.

Can you post your command?

You need to add the --ro option and make sure LIBGUESTFS_BACKEND=direct.

Sure, I'm using the attached test script.

I used your script to test, but I don't see errors as you posted,
attached the output. The only difference is that I put libguestfs in
different directory with you and I'm using a linux guest image instead
of windows xp. Do I need to get a windows image to reproduce?

There's actually an error in the output of libguestfs.  As a result
the test didn't fully run.  The error is hidden in all the extra
debugging information we're printing, but here it is:

You need to install the Augeas development package (augeas-devel on
Fedora, libaugeas-dev on Debian) and recompile libguestfs.  It's a
good idea to make sure you have every dependency installed by doing:

  yum-builddep libguestfs

or

  apt-get build-dep libguestfs

(this is covered in the libguestfs README).

- - -

I'm not sure if a Windows guest is somehow necessary to show the
errors.  I'll retest with a Linux guest and get back to you about
that.

Also I'm testing against a remote Apache2 server over a very slow Wifi
connection.  Whereas your test was against localhost.  Again, I will
test this scenario to see if that makes a difference and get back to
you.

Reproducible with Linux guest (remotely over slow Wifi).

NOT reproducible with Windows XP guest over localhost, Apache2 server.

So it seems to have something to do with the long latency and/or low
bandwidth of the slow wifi connection here.

I will add: This bug is not 100% reproducible on every run.  However
it does occur very frequently, probably in 9 out of 10 runs for me.

OK, I'll try a remote image then.

FWIW attached are a couple of runs with the Linux guest, remote.

I killed them both because there were so many errors and they weren't
making much progress.

Re: [Qemu-devel] [PATCH v6 00/12] curl: fix curl read

[Richard W.M. Jones]

After discussion off-list, I've gone back and retested versions 4, 5,
and 6 of this patch.

I'm using the test script previously attached.

I'm using libguestfs (ada94eb9) & curl (ba9a6666) & qemu (6a4e177114)
all the latest from git.

I'm using a 6 GB Windows XP guest.  The web server is remote, over
quite slow wifi, and is running Apache 2.2.15 on RHEL 6.

I ran each test 3 times.

v4:

  Buffer I/O errors reported inside the appliance on each run.
  No segfault in qemu.

v5:

  Buffer I/O errors reported inside the appliance on each run.
  No segfault in qemu.

v6:

  Buffer I/O errors reported inside the appliance on each run.
  No segfault in qemu.

no patch (curl driver in upstream qemu):

  No errors.  Everything works.

--

So I guess what has happened is NOT a regression from v5 -> v6, but
that something has changed in my environment which has stopped this
patch from working.

I'm continuing to investigate.

Rich.

Some more data points:

v6 patch, with my laptop plugged directly into the gigabit ethernet
switch which is connected to the web server:

 - Worked perfectly 5 times in a row.

v6 patch, with my laptop next to the wifi aerial:

 - Bug is harder to reproduce, maybe only happens 50% of runs.

v6 patch, with my laptop about 100' from the wifi aerial:

 - Bug reproduces on every run.

So something to do with long latency links.

Question: Is there a place in the patch we could put a sleep in order
to simulate a long latency link?

I also checked the logs on the web server.  There are no errors, and
each access returned a 200 or 206.  So the problem doesn't appear to
be at the web server end.

There seems no easy way to me to inject sleep to io reqs in curl.c.
Another option might be configure & compile qemu with
CFLAGS=-DDEBUG_CURL and grab the stdout, so that we can see how requests
are processed.

No problems.

I started with v6 patch.  I did:

$ CFLAGS=-DDEBUG_CURL ./configure --enable-werror --target-list="i386-softmmu x86_64-softmmu"
$ make

Note there is a bug!

block/curl.c: In function ‘curl_complete_io’:
block/curl.c:211:5: error: too many arguments for format [-Werror=format-extra-args]
cc1: all warnings being treated as errors
make: *** [block/curl.o] Error 1

Please add the attached patch to your patch set.

After fixing that and continuing the build, I then ran:

$ /tmp/test.sh >& /tmp/curl-debug.log

This shows the error and produces an absolutely vast amount of
debugging (attached).  Note that I killed it after a while but there
should be enough to show the error.

This fixes the obvious bug.

I wonder if it should be even larger?  One use for curl is to install
guests using ISOs from websites without having to download the ISO,
and I imagine that even a 30 second timeout could be conservative for
that task.

Something like this?

Thanks for figuring out this. Mainline had this 5s timeout so I kept it,
but you don't experience this bug, right? Since master doesn't setup a
timer to get curl notified about the timing, the option is just not
effective.

Long latency network is common in practice, as well as low bandwidth,
the meaning of the timeout is to complete the request, in extreme cases
if it is a 1Kbps link, downloading 256k takes minutes. Anyway, I think
making it larger won't hurt.

Indeed, qemu master has:

    curl_easy_setopt(state->curl, CURLOPT_TIMEOUT, 5);

but I don't encounter the bug when using master, and I'm pretty
certain about that because I've tested it a lot.

It could be that qemu master manages to recover from / restart these
incomplete reads, and doesn't deliver EIO up to the guest.

I tried playing around with timeouts yesterday.

Inside the guest there is a SCSI timeout (30 seconds default, see
[1]).  This has to be made larger if we make the qemu timeout larger
than 30 seconds.

With upstream qemu I can increase this timeout to 180 seconds and so
read ISOs from slow public websites.  (Try changing the test script so
the 'disk' variable points to an ISO such as [2]).

With the v6 patch, adjusting the SCSI timeout in the guest doesn't
have any effect -- the SCSI disk "aborts" after ~40 seconds whatever I
do.
