The following patch should nicely fix the problem allowing all users to reconfigure downed interfaces mac addresses. Fortunately most setups make this very hard to attack. The patch is v 2.0.30 but should apply cleanly to all 2.0.x kernels and most 1.3 kernels. 1.2 also has this problem. The patch won't apply directly but the change is identical. --- net/core/dev.c~ Tue Apr 8 16:47:47 1997 +++ net/core/dev.c Tue May 27 18:16:03 1997 @@ -1427,7 +1427,6 @@ case SIOCGIFMTU: case SIOCGIFMEM: case SIOCGIFHWADDR: - case SIOCSIFHWADDR: case SIOCGIFSLAVE: case SIOCGIFMAP: return dev_ifsioc(arg, cmd); @@ -1444,6 +1443,7 @@ case SIOCSIFMETRIC: case SIOCSIFMTU: case SIOCSIFMEM: + case SIOCSIFHWADDR: case SIOCSIFMAP: case SIOCSIFSLAVE: case SIOCADDMULTI: Alan
