Subject: [PATCH] python: Fix crash when passing None as a buffer
|
||||
|
||||
$ nbdkit -U - null 512 --run 'nbdsh -u $uri -c "h.pwrite(None, 0)"'
|
||||
nbdkit: external command was killed by signal 11
|
||||
|
||||
The stack trace indicated that the code was calling
|
||||
PyBuffer_Release (&buf) on an uninitialized buffer 'buf'. What was
|
||||
happening was that PyArg_ParseTuple was recognizing the type error in
|
||||
the parameter (None is not a buffer-like object) and failing, but it
|
||||
didn't initialize the Py_buffer parameter so that contained random
|
||||
stuff from the stack, and then we tried to release it by calling
|
||||
PyBuffer_Release.
|
||||
|
||||
To fix this, initialize the stack buffer, then avoid calling
|
||||
PyBuffer_Release if the .obj field in the Py_buffer is still NULL
|
||||
(which should be impossible if PyArg_ParseTuple set the &buf
|
||||
parameter).
|
||||
|
||||
After this commit we see the type error:
|
||||
|
||||
$ nbdkit -U - null 512 --run './run nbdsh -u $uri -c "h.pwrite(None, 0)"'
|
||||
Traceback (most recent call last):
|
||||

||||

Subject: [PATCH] lib/poll.c: Retry poll after EINTR
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|

||||
I see a rare random failure when calling BlockStatus via Go binding:
|
||||
|
||||
block_status: nbd_block_status: poll: Interrupted system call
|
||||
|
||||
I could not reproduce this with "nbdinfo --map", even after modifying it
|
||||
to call nbd_block_status() for every 128 MiB.
|
||||
|
||||
Fixing this in nbd_unlock_poll() avoids this issue in the entire
|
||||
library, when we wait for command completion. This seems more useful
|
||||
that fixing it in all libnbd clients.
|
||||
|
||||
Tested using a go client listing all extents in an image, calling
|
||||
BlockStatus for every 128m with fedora 34 qcow2 image. Without this fix,
|
||||
this was always failing.
|
||||
|
||||
$ hyperfine -r1000 --show-output "./client nbd+unix://?socket=/tmp/nbd.sock > /dev/null"
|
||||
Benchmark 1: ./client nbd+unix://?socket=/tmp/nbd.sock > /dev/null
|
||||
Time (mean ± σ): 31.6 ms ± 3.1 ms [User: 8.8 ms, System: 7.2 ms]
|
||||
Range (min … max): 26.1 ms … 52.3 ms 1000 runs
