Re: [PATCH 05/13] meson: Disable -fsanitize=function

Strictly speaking, xdrproc_t is declared as following: typedef bool_t (*xdrproc_t)(XDR *, ...); But our rpcgen generates properly typed functions, e.g.: bool_t xdr_virNetMessageError(XDR *xdrs, virNetMessageError *objp) Now, these functions of ours are passed around as callbacks (via an argument of xdrproc_t type), for instance in virNetMessageEncodePayload(). But these two types are strictly different. We silence the compiler by typecasting the callbacks when passing them, but strictly speaking - calling such callback later, when a function of xdrproc_t is expected is an undefined behavior. Ideally, we would fix our rpcgen to generate proper function headers, but: a) my brain is too small to do that, and b) we would lose compiler protection if an xdr_*() function is called directly but argument of a wrong type is passed.

Silence UBSAN for now. Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com&gt; --- meson.build | 13 +++++++++++++ 1 file changed, 13 insertions(+)
