Hi,
Static analysis with Coverity detected an issue in function bareudp_xmit_skb with the return of an uninitialized value in variable err in the following commit:
commit 571912c69f0ed731bd1e071ade9dc7ca4aa52065 Author: Martin Varghese <martin.varghese@nokia.com> Date: Mon Feb 24 10:57:50 2020 +0530
net: UDP tunnel encapsulation module for tunnelling different protocols like MPLS, IP, NSH etc.
The analysis is as follows:
var_decl: Declaring variable err without initializer.
301 int err; 302
...
344 free_dst: 345 dst_release(&rt->dst);
Uninitialized scalar variable (UNINIT) uninit_use: Using uninitialized value err.
346 return err; 347 }
and also in function bareudp6_xmit_skb:
var_decl: Declaring variable err without initializer.
364 int err; 365
...
404 405 free_dst: 406 dst_release(dst);
Uninitialized scalar variable (UNINIT) uninit_use: Using uninitialized value err.
407 return err; 408 }
Colin
