Subject: [PATCH] Check and report for incomplete 'global' option format
|
|
mainline inclusion commit 818e1636080768749dc826acd4825e71828ec7e6 category:
|
|
bugfix
|
|
|
|
---------------------------------------------------------------
|
|
|
|
Qemu might crash when provided incomplete '-global' option.
|
|
For example:
|
|
qemu-system-x86_64 -global driver=isa-fdc
|
|
qemu-system-x86_64: ../../devel/qemu/qapi/string-input-visitor.c:394:
|
|
string_input_visitor_new: Assertion `str' failed.
|
|
Aborted (core dumped)
|
|
|
|
Fixes: 3751d7c43f795b ("vl: allow full-blown QemuOpts syntax for -global")
