Hi; I am working width a project intended for developing an adaptive class based QoS system for Linux. I have been struggling width a bug for a long time now. The bug has been tracked to procedure tc_ctl_class() in file linux/net/sched/sch_api.c. In this function there are a switch test, in order to test whether NEWCLASS or other flags are set. If RTM_NEWCLASS flag is set, a if test is performed: if (n->nlmsg_flags&NLM_F_EXCL) What does this if test perform, especially what does NLM_F_EXCL flag represent. When I attach a new class, this test result true. The next step after a goto call, is to test if there are a class pointer. If there are a class pointer, an oops call "oops->put(q, cl)" is done.. In this call my system crash. Is there any approach in order to solve the oops. ?? Lars Landmark Student
