The crashes are on 22.11, 23.03, 24.11, it is on all dpdk stable versions and 25.07 as well. Please first close primary testpmd before secondary testpmd application and try to close secondary or execute any of the following commands,
"show device info all show port stats all show port xstats all set fwd rxonly set fwd txonly start etc" We are all agree that these crashes exists. First we were tried to prevent the crashes at PMD level, but it was not possible to add checks in each PMD. Then we tried to add safety checks in ethdev layer, and it was not suitable as with primary closing all reference to device information (pointers) would lead crashes. Then we agreed on secondary process monitoring for primary process exiting. and it is now resolved on application level, i.e. on testpmd. Now, this solution is working perfectly. We can add eal_cleanup for gracefull exit. Best Regards, Khadem
