Hi Michal/DPDK-Experts, I am facing one issue in net/ena driver while fetching extended stats (xstats). The DPDK seems to segfault with below backtrace.
DPDK Version: 20.11.1 ENA version: 2.2.1 Using host libthread_db library "/lib64/libthread_db.so.1". Core was generated by `/opt/dpfs/usr/local/bin/brdagent'. Program terminated with signal SIGSEGV, Segmentation fault. #0 __memmove_avx_unaligned_erms () at ../sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S:232 232 VMOVU %VEC(0), (%rdi) [Current thread is 1 (Thread 0x7fffed93a400 (LWP 5060))] Thread 1 (Thread 0x7fffed93a400 (LWP 5060)): #0 __memmove_avx_unaligned_erms () at ../sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S:232 #1 0x00007ffff3c246df in ena_com_handle_admin_completion () from ../lib64/../../lib64/libdpdk.so.20 #2 0x00007ffff3c1e7f5 in ena_interrupt_handler_rte () from ../lib64/../../lib64/libdpdk.so.20 #3 0x00007ffff3519902 in eal_intr_thread_main () from /../lib64/../../lib64/libdpdk.so.20 #4 0x00007ffff510714a in start_thread (arg=<optimized out>) at pthread_create.c:479 #5 0x00007ffff561ff23 in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:95 *Background:* - This used to work fine with DPDK-19.11.3 , that means there was no crash observed with the 19.11.3 DPDK version, but now after upgrading to DPDK 20.11.1, DPDK is crashing with the above trace. - It looks to me as a DPDK issue. - I could see multiple fixes/patches in the net/ena area, but not able to identify which patch would exactly fix this issue. For example: http://git.dpdk.org/dpdk/diff/?h=releases&id=aab58857330bb4bd03f6699bf1ee716f72993774 https://inbox.dpdk.org/dev/20210430125725.28796-6...@semihalf.com/T/#me99457c706718bb236d1fd8006ee7a0319ce76fc Could you please help here and let me know what patch could fix this issue.
