255.255.255.0, and a default route with gateway x.x.x.1. Now if the address mask is changed to something more specific, e.g., 255.255.255.128, then after the mask change the default gateway is no longer reachable. Since the default route is still present in the routing table, when the output code tries to resolve the address of the default gateway in function rt_check(), again, the default route will be returned by rtalloc1(). Because the lock is currently held on the rtentry structure, one more attempt to hold the lock will trigger a crash due to "lock recursed on non-recursive mutex ..." This is a general problem. The fix checks for the above condition so that an existing route entry is not mistaken for a new cloned route. Approriately, an ENETUNREACH error is returned back to the caller Approved by: andre |
