Subject: [PATCH] qemu-img: Use only string options in img_open_opts
|
|
|
|
img_open_opts() takes a QemuOpts and converts them to a QDict, so all
|
|
values therein are strings. Then it may try to call qdict_get_bool(),
|
|
however, which will fail with a segmentation fault every time:
|
|
|
|
$ ./qemu-img info -U --image-opts \
|
|
driver=file,filename=/dev/null,force-share=off
|
|
[1] 27869 segmentation fault (core dumped) ./qemu-img info -U
|
|
--image-opts driver=file,filename=/dev/null,force-share=off
|
|
|
|
Fix this by using qdict_get_str() and comparing the value as a string.
|
|
Also, when adding a force-share value to the QDict, add it as a string
|
|
so it fits the rest of the dict.
