When attempting to do a blockpull the following error occurs and the VM crashes.
qemu-system-x86_64: /build/qemu-Eap4uc/qemu-2.11+dfsg/block/io.c:1042: bdrv_co_do_copy_on_readv: Assertion `skip_bytes < pnum' failed.
2019-02-17 17:38:27.820+0000: shutting down, reason=crashed
This appears to be fixed upstream.
https://patchwork.kernel.org/patch/10512135/
https://github.com/qemu/qemu/commit/b0ddcbbb36a66a605eb232b905cb49b1cc72e74e |
[Impact]
* During qemu-io VM disk read, there is a possibility for qemu-io to
abort crashing the process running. This also crashes the VM the read
is running against.
* Backport upstream fix from
[Test Case]
* Steps to reproduce outside of a block pull:
$ qemu-img create -f qcow2 test 1024 2>&1
$ qemu-io -f qcow2 -C -c 'read 0 1024' test
Without the fix:
Error:
qemu-io: /build/qemu-Eap4uc/qemu-2.11+dfsg/block/io.c:1042:
bdrv_co_do_copy_on_readv: Assertion `skip_bytes < pnum' failed.
Aborted (core dumped)
With fix:
read 1024/1024 bytes at offset 0
1 KiB, 1 ops; 0.0045 sec (220.604 KiB/sec and 220.6045 ops/sec)
[Regression Potential]
* The change is small and unchanged since two releases which indicates it
is rather stable. The only thing it adds is a safety check on ret&&pnum
being zero to leave the loop.
The only related regression I could think of is leaving the loop too
early, but when pnum==0 it has nothing more to write, so there should
be no issue to leave.
[Other Info]
* n/a
