<!DOCTYPE html> <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> </head> <body> Good afternoon, When running latest DPDK, commit fd233ad17e5ffa42d50f1625165a7fce3f1cbc5f, I have a found an issue with running the qos_sched app with the configuration file present at the end of this email. DPDK was built with the following options. meson --reconfigure --buildtype=debugoptimized -Dexamples=qos_sched -Db_sanitize=address build The process is run as follows. Of note, with the default config files, the process starts and is executed as expected. .build/examples/dpdk-qos_sched -l 29-32 -n 4 -a 86:01.0 -a 86:01.1 -a 86:01.2 -- --pfc "0,0,30,31,32" --cfg /home/ubuntu/dpdk/examples/qos_sched/65kpipe_25gb_pipe_alloc_buggy.cfg --mnc 29 --bsz "128,512,511,511" --rsz "4096,32768,4096" -i The error seen is the following. EAL: Detected CPU lcores: 112 EAL: Detected NUMA nodes: 2 EAL: Detected static linkage of DPDK EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: Selected IOVA mode 'VA' EAL: VFIO support initialized EAL: Using IOMMU type 1 (Type 1) Interactive-mode selected APP: Initializing port 11... ETHDEV: Invalid port_id=11 EAL: Error - exiting with code: 1 Error during getting device (port 11) info: No such device The following is the ASAN output. I am unfortunately unable to pursue this any further. Could anyone please give some assistance? ================================================================= ==253445==ERROR: AddressSanitizer: global-buffer-overflow on address 0x62117f738b20 at pc 0x62117cda077f bp 0x7ffd06c50ae0 sp 0x7ffd06c50ad0 WRITE of size 4 at 0x62117f738b20 thread T0 #0 0x62117cda077e in cfg_load_subport ../examples/qos_sched/cfg_<a class="moz-txt-link-freetext" href="file.c:422">file.c:422</a> #1 0x62117cda13be in app_load_cfg_profile ../examples/qos_sched/<a class="moz-txt-link-freetext" href="init.c:304">init.c:304</a> #2 0x62117cda13be in app_init ../examples/qos_sched/<a class="moz-txt-link-freetext" href="init.c:336">init.c:336</a> #3 0x62117cd32ae5 in main ../examples/qos_sched/<a class="moz-txt-link-freetext" href="main.c:190">main.c:190</a> #4 0x76846842a1c9 in __libc_start_call_main ../sysdeps/nptl/libc_start_call_<a class="moz-txt-link-freetext" href="main.h:58">main.h:58</a> #5 0x76846842a28a in __libc_start_main_impl ../csu/<a class="moz-txt-link-freetext" href="libc-start.c:360">libc-start.c:360</a> #6 0x62117cd989a4 in _start (/home/ubuntu/dpdk-tryout/build/examples/dpdk-qos_sched+0xc069a4) (BuildId: 8d0f5fdb7beb728ce95a88abe602fdd7766f27be) 0x62117f738b20 is located 0 bytes after global variable 'active_queues' defined in '../examples/qos_sched/cfg_<a class="moz-txt-link-freetext" href="file.c:23:10">file.c:23:10</a>' (0x62117f738ae0) of size 64 SUMMARY: AddressSanitizer: global-buffer-overflow ../examples/qos_sched/cfg_<a class="moz-txt-link-freetext" href="file.c:422">file.c:422</a> in cfg_load_subport Shadow bytes around the buggy address: 0x62117f738880: 00 f9 f9 f9 f9 f9 f9 f9 00 f9 f9 f9 f9 f9 f9 f9 0x62117f738900: 04 f9 f9 f9 f9 f9 f9 f9 00 00 00 00 00 00 00 00 0x62117f738980: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x62117f738a00: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 04 0x62117f738a80: f9 f9 f9 f9 04 f9 f9 f9 f9 f9 f9 f9 00 00 00 00 =>0x62117f738b00: 00 00 00 00[f9]f9 f9 f9 00 00 00 00 00 00 00 00 0x62117f738b80: 00 00 00 00 00 00 00 00 00 00 00 00 f9 f9 f9 f9 0x62117f738c00: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x62117f738c80: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x62117f738d00: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x62117f738d80: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Shadow byte legend (one shadow byte represents 8 application bytes): Addressable: 00 Partially addressable: 01 02 03 04 05 06 07 Heap left redzone: fa Freed heap region: fd Stack left redzone: f1 Stack mid redzone: f2 Stack right redzone: f3 Stack after return: f5 Stack use after scope: f8 Global redzone: f9 Global init order: f6 Poisoned by user: f7 Container overflow: fc Array cookie: ac Intra object redzone: bb ASan internal: fe Left alloca redzone: ca Right alloca redzone: cb ==253445==ABORTING ; Port configuration [port] frame overhead = 24 number of subports per port = 2 subport 0 = 0 subport 1 = 0 ; Subport configuration [subport 0] number of pipes per subport = 2 queue sizes = 64 64 64 64 64 64 64 64 64 64 64 64 64 pipe 0 - 1 = 0 ; These pipes are configured with pipe profile 0 ; Subport configuration [subport 1] number of pipes per subport = 2 queue sizes = 64 64 64 64 64 64 64 64 64 64 64 64 64 pipe 0 - 1 = 0 ; These pipes are configured with pipe profile 0 [subport profile 0] tb rate = 3125000000 ; Bytes per second tb size = 1000000000 ; Bytes tc 0 rate = 3125000000 ; Bytes per second tc 1 rate = 3125000000 ; Bytes per second tc 2 rate = 3125000000 ; Bytes per second tc 3 rate = 3125000000 ; Bytes per second tc 4 rate = 3125000000 ; Bytes per second tc 5 rate = 3125000000 ; Bytes per second tc 6 rate = 3125000000 ; Bytes per second tc 7 rate = 3125000000 ; Bytes per second tc 8 rate = 3125000000 ; Bytes per second tc 9 rate = 3125000000 ; Bytes per second tc 10 rate = 3125000000 ; Bytes per second tc 11 rate = 3125000000 ; Bytes per second tc 12 rate = 3125000000 ; Bytes per second tc period = 10 ; Milliseconds ; Pipe configuration [pipe profile 0] tb rate = 750000 ; Bytes per second tb size = 10000 ; Bytes tc 0 rate = 750000 ; Bytes per second tc 1 rate = 750000 ; Bytes per second tc 2 rate = 750000 ; Bytes per second tc 3 rate = 750000 ; Bytes per second tc 4 rate = 750000 ; Bytes per second tc 5 rate = 750000 ; Bytes per second tc 6 rate = 750000 ; Bytes per second tc 7 rate = 750000 ; Bytes per second tc 8 rate = 750000 ; Bytes per second tc 9 rate = 750000 ; Bytes per second tc 10 rate = 750000 ; Bytes per second tc 11 rate = 750000 ; Bytes per second tc 12 rate = 750000 ; Bytes per second tc period = 20 ; Milliseconds tc 12 oversubscription weight = 1 tc 12 wrr weights = 1 1 1 1 </body> </html> <div>BISDN GmbH</div><div>Körnerstraße 7-10</div><div>10785 Berlin</div><div>Germany</div><div> </div><div>Phone: +49-30-6108-1-6100</div><div> </div><div>Managing Directors: </div><div>Dr.-Ing.
