For example if total data transferred was (simplified) 100,000,000 Bytes, iperf would print Sum: 100 Mbytes. The suffix Mbytes is stored in a static array and it uses the number of time it had to divide the sum by 1000 to determine the index to that array. iperf only accounted for Sums up to GBytes, causing it to segfault on Sums of +TBytes. Currently the patch extends this array to Peta Bytes, but you will segfault again if the sum is in the order of Exabyte or larger. This might be achievable by using 100G connections between server-client (Mellanox 100G nic & switch) and running iperf at max throughput for a long long long periods of time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1771283 Title: iperf2 long time run on 40Gb/s NIC crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/iperf/+bug/1771283/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1771283] Re: iperf2 long time run on 40Gb/s NIC crashes
Robert, Please review and consider this patch to iperf to fix the segfault. Looks like in function byte_snprintf() when calculating SUM, where SUM is in terabyte, we go past the kLabel_Byte/kLabel_bit array limit (by increment of conv past kConv_Giga) and this causes iperf to segfault because suffix is pointing past the array bounds. The attached patch addresses this issue. -- Before patch -- $ iperf -c 192.168.120.2 -P10 -w 130k -t 1200 Client connecting to 192.168.120.2, TCP port 5001 TCP window size: 254 KByte (WARNING: requested 127 KByte) [ 12] local 192.168.120.3 port 47668 connected with 192.168.120.2 port 5001 [ 10] local 192.168.120.3 port 47664 connected with 192.168.120.2 port 5001 [ 11] local 192.168.120.3 port 47666 connected with 192.168.120.2 port 5001 [ 8] local 192.168.120.3 port 47662 connected with 192.168.120.2 port 5001 [ 5] local 192.168.120.3 port 47656 connected with 192.168.120.2 port 5001 [ 4] local 192.168.120.3 port 47650 connected with 192.168.120.2 port 5001 [ 6] local 192.168.120.3 port 47654 connected with 192.168.120.2 port 5001 [ 9] local 192.168.120.3 port 47660 connected with 192.168.120.2 port 5001 [ 7] local 192.168.120.3 port 47658 connected with 192.168.120.2 port 5001 [ 3] local 192.168.120.3 port 47652 connected with 192.168.120.2 port 5001 [ ID] Interval Transfer Bandwidth [ 12] 0.0-1200.0 sec 73.3 GBytes 525 Mbits/sec [ 10] 0.0-1200.0 sec 164 GBytes 1.17 Gbits/sec [ 11] 0.0-1200.0 sec 219 GBytes 1.57 Gbits/sec [ 8] 0.0-1200.0 sec 73.3 GBytes 525 Mbits/sec [ 5] 0.0-1200.0 sec 164 GBytes 1.18 Gbits/sec [ 4] 0.0-1200.0 sec 165 GBytes 1.18 Gbits/sec [ 6] 0.0-1200.0 sec 109 GBytes 784 Mbits/sec [ 9] 0.0-1200.0 sec 165 GBytes 1.18 Gbits/sec [ 7] 0.0-1200.0 sec 109 GBytes 783 Mbits/sec [ 3] 0.0-1200.0 sec 73.3 GBytes 525 Mbits/sec Segmentation fault (core dumped) -- After patch -- $ src/iperf -c 192.168.120.2 -P10 -w 130k -t 1200 Client connecting to 192.168.120.2, TCP port 5001 TCP window size: 254 KByte (WARNING: requested 127 KByte) [ 12] local 192.168.120.3 port 47626 connected with 192.168.120.2 port 5001 [ 8] local 192.168.120.3 port 47616 connected with 192.168.120.2 port 5001 [ 10] local 192.168.120.3 port 47622 connected with 192.168.120.2 port 5001 [ 3] local 192.168.120.3 port 47610 connected with 192.168.120.2 port 5001 [ 9] local 192.168.120.3 port 47620 connected with 192.168.120.2 port 5001 [ 4] local 192.168.120.3 port 47608 connected with 192.168.120.2 port 5001 [ 7] local 192.168.120.3 port 47614 connected with 192.168.120.2 port 5001 [ 11] local 192.168.120.3 port 47624 connected with 192.168.120.2 port 5001 [ 5] local 192.168.120.3 port 47612 connected with 192.168.120.2 port 5001 [ 6] local 192.168.120.3 port 47618 connected with 192.168.120.2 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-1200.0 sec 142 GBytes 1.02 Gbits/sec [ 9] 0.0-1200.0 sec 120 GBytes 862 Mbits/sec [ 11] 0.0-1200.0 sec 121 GBytes 867 Mbits/sec [ 5] 0.0-1200.0 sec 122 GBytes 874 Mbits/sec [ 12] 0.0-1200.0 sec 120 GBytes 856 Mbits/sec [ 8] 0.0-1200.0 sec 122 GBytes 871 Mbits/sec [ 10] 0.0-1200.0 sec 146 GBytes 1.04 Gbits/sec [ 4] 0.0-1200.0 sec 141 GBytes 1.01 Gbits/sec [ 7] 0.0-1200.0 sec 122 GBytes 873 Mbits/sec [ 6] 0.0-1200.0 sec 143 GBytes 1.02 Gbits/sec [SUM] 0.0-1200.0 sec 1299 GBytes 9.30 Gbits/sec ** Patch added: "fix segfault in iperf" https://bugs.launchpad.net/ubuntu/+source/iperf/+bug/1771283/+attachment/5147771/+files/0001-Fix-segfault-while-calculating-sum-on-long-iperf-run.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1771283 Title: iperf2 long time run on 40Gb/s NIC crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/iperf/+bug/1771283/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I will submit an SRU for B/A/X releases. ubuntu@recht:~/iperf-2.0.10+dfsg1$ src/iperf -c 192.168.120.2 -P10 -w 130k -t 3600 Client connecting to 192.168.120.2, TCP port 5001 TCP window size: 254 KByte (WARNING: requested 127 KByte) [ 11] local 192.168.120.3 port 58206 connected with 192.168.120.2 port 5001 [ 4] local 192.168.120.3 port 58192 connected with 192.168.120.2 port 5001 [ 5] local 192.168.120.3 port 58194 connected with 192.168.120.2 port 5001 [ 3] local 192.168.120.3 port 58196 connected with 192.168.120.2 port 5001 [ 7] local 192.168.120.3 port 58198 connected with 192.168.120.2 port 5001 [ 6] local 192.168.120.3 port 58200 connected with 192.168.120.2 port 5001 [ 9] local 192.168.120.3 port 58202 connected with 192.168.120.2 port 5001 [ 10] local 192.168.120.3 port 58204 connected with 192.168.120.2 port 5001 [ 12] local 192.168.120.3 port 58208 connected with 192.168.120.2 port 5001 [ 8] local 192.168.120.3 port 58210 connected with 192.168.120.2 port 5001 [ ID] Interval Transfer Bandwidth [ 11] 0.0-3600.0 sec 157 GBytes 376 Mbits/sec [ 4] 0.0-3600.0 sec 986 GBytes 2.35 Gbits/sec [ 5] 0.0-3600.0 sec 981 GBytes 2.34 Gbits/sec [ 3] 0.0-3600.0 sec 113 GBytes 269 Mbits/sec [ 7] 0.0-3600.0 sec 495 GBytes 1.18 Gbits/sec [ 6] 0.0-3600.0 sec 493 GBytes 1.18 Gbits/sec [ 9] 0.0-3600.0 sec 257 GBytes 614 Mbits/sec [ 10] 0.0-3600.0 sec 112 GBytes 268 Mbits/sec [ 12] 0.0-3600.0 sec 113 GBytes 270 Mbits/sec [ 8] 0.0-3600.0 sec 238 GBytes 568 Mbits/sec [SUM] 0.0-3600.0 sec 4236189630464 bits 9.41 Gbits/sec -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1771283 Title: iperf2 long time run on 40Gb/s NIC crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/iperf/+bug/1771283/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1771283] Re: iperf2 long time run on 40Gb/s NIC crashes
byte_snprintf() calls snprintf() with a bad format pointer and snprintf() segfaults. The root cause of the bad pointer is very elusive because there is so much information being printed. Further debug needed to find out the root cause. -- with GDB and debug -- (gdb) bt #0 strlen () at ../sysdeps/aarch64/strlen.S:94 #1 0xa35b5f18 in _IO_vfprintf_internal (s=s@entry=0x99ffa578, format=format@entry=0xd52878f0 "%4.0f %s", ap=...) at vfprintf.c:1643 #2 0xa364ca64 in ___vsnprintf_chk ( s=s@entry=0xd529a280 "4235479613440 ", maxlen=, maxlen@entry=32, flags=flags@entry=1, slen=slen@entry=18446744073709551615, format=0xd52878f0 "%4.0f %s", args=...) at vsnprintf_chk.c:63 #3 0xa364c980 in ___snprintf_chk ( s=s@entry=0xd529a280 "4235479613440 ", maxlen=maxlen@entry=32, flags=flags@entry=1, slen=slen@entry=18446744073709551615, format=) at snprintf_chk.c:34 #4 0xd5283cb8 in snprintf (__fmt=, __n=32, __s=0xd529a280 "4235479613440 ") at /usr/include/aarch64-linux-gnu/bits/stdio2.h:64 #5 byte_snprintf ( outString=outString@entry=0xd529a280 "4235479613440 ", inLen=inLen@entry=32, inNum=, inFormat=) at stdio.c:247 #6 0xd527d928 in reporter_multistats (stats=0xaaab104a38e0) at ReportDefault.c:205 #7 0xd527f264 in reporter_print (stats=0xaaab104a3850, type=type@entry=16, end=end@entry=1) at Reporter.c:1154 #8 0xd527f628 in reporter_handle_multiple_reports ( reporthdr=reporthdr@entry=0xaaab104a37c0, stats=stats@entry=0xa03910a8, force=force@entry=1) at Reporter.c:996 #9 0xd527f938 in reporter_condprintstats (stats=0xa0391018, multireport=0xaaab104a37c0, force=1) at Reporter.c:1075 #10 0xd527fd6c in reporter_process_report (reporthdr=0xa0391010) at Reporter.c:759 #11 0xd527fdfc in reporter_process_report (reporthdr=0xa04cb010) at Reporter.c:719 #12 0xd527fdfc in reporter_process_report (reporthdr=0xa01ba010) at Reporter.c:719 #13 0xd527fdfc in reporter_process_report (reporthdr=0xa0080010) at Reporter.c:719 #14 0xd527fdfc in reporter_process_report ( reporthdr=reporthdr@entry=0xa02f4010) at Reporter.c:719 #15 0xd527ff10 in reporter_spawn (thread=0xaaab104a5cd0) at Reporter.c:627 #16 0xd52843cc in thread_run_wrapper (paramPtr=0xaaab104a5cd0) at Thread.c:247 #17 0xa36ce088 in start_thread (arg=0xc669f3ff) at pthread_create.c:463 #18 0xa363e4ec in thread_start () at ../sysdeps/unix/sysv/linux/aarch64/clone.S:78 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1771283 Title: iperf2 long time run on 40Gb/s NIC crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/iperf/+bug/1771283/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Is your packet size bigger than the MTU size? Could you use jumbo and see if you still see this issue? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1771283 Title: iperf2 long time run on 40Gb/s NIC crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/iperf/+bug/1771283/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
