Summary
RDMA/cma: Do not change route.addr.src_addr outside state checks
Details

In the Linux kernel, the following vulnerability has been resolved:

RDMA/cma: Do not change route.addr.src_addr outside state checks

If the state is not idle then resolvepreparesrc() should immediately fail and no change to global state should happen. However, it unconditionally overwrites the src_addr trying to build a temporary any address.

For instance if the state is already RDMACMLISTEN then this will corrupt the srcaddr and would cause the test in cmacancel_operation():

       if (cma_any_addr(cma_src_addr(id_priv)) && !id_priv->cma_dev)

Which would manifest as this trace from syzkaller:

BUG: KASAN: use-after-free in _listaddvalid+0x93/0xa0 lib/listdebug.c:26 Read of size 8 at addr ffff8881546491e0 by task syz-executor.1/32204

This is indicating that an rdmaidprivate was destroyed without doing cmacancellistens().

Instead of trying to re-use the srcaddr memory to indirectly create an any address derived from the dst build one explicitly on the stack and bind to that as any other normal flow would do. rdmabindaddr() will copy it over the srcaddr once it knows the state is valid.

This is similar to commit bc0bdc5afaa7 ("RDMA/cma: Do not change route.addr.srcaddr.ssfamily")
