https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D275061 Bug ID: 275061 Summary: net/realtek-re-kmod causes memory modification after free Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: ale@FreeBSD.org Reporter: karels@freebsd.org Flags: maintainer-feedback?(ale@FreeBSD.org) Assignee: ale@FreeBSD.org Created attachment 246276 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D246276&action= =3Dedit crashinfo output for one crash I tried to switch a 15-CURRENT system from em interface to re using the dri= ver from packages today. It caused crashes twice while the system was still starting up before I gave up. One was in nfs code, one in tcp code, alloca= ting an mbuf. The memory was modified at an offset of 8, changing deadc0de to deadbdc2. I'll attach a crashinfo report. The system has been running fai= rly reliably. It has local kernel modifications, but not in the network code.
