Revision 3201e656ce56ed02e9501906c18ffe16ae350a52 authored by Jay Vosburgh on 19 June 2007, 18:12:12 UTC, committed by Jeff Garzik on 20 June 2007, 23:12:41 UTC
The following patch (based on a patch from Stephen Hemminger <shemminger@linux-foundation.org>) removes use after free conditions in the unregister path for the bonding master. Without this patch, an operation of the form "echo -bond0 > /sys/class/net/bonding_masters" would trigger a NULL pointer dereference in sysfs. I was not able to induce the failure with the non-sysfs code path, but for consistency I updated that code as well. I also did some testing of the bonding /proc file being open while the bond is being deleted, and didn't see any problems there.
