When an interface has IFF_LOOPBACK flag in6_ifattach() tries to assing IPv6 loopback address to this interface. It uses in6ifa_ifpwithaddr() to check, that interface doesn't already have given address and then uses in6_ifattach_loopback(). If in6_ifattach_loopback() fails, it just exits and thus skips assignment of IPv6 LLA. Fix this using in6ifa_ifwithaddr() function. If IPv6 loopback address is already assigned in the system, do not call in6_ifattach_loopback().

Actually, delay under 6.3-RELEASE is lower ( and evaluate time is higher ) because 6.3-RELEASE is running on different hardware. Test load (Fibonacci calculation) is executed faster under modern hardware. I will try to install 6.3-RELEASE on Moxa hardware, repeat test and report result. Unfortunelly, I need to have test running for at least 6 hours befo= re I get reliable results. --=20 You are receiving this mail because: You are the assignee for the bug.= From owner-freebsd-net@freebsd.org Tue Jan 30 12:33:43 2018 Return-Path: Delivered-To: freebsd-net@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 9D797EC788E for ;

One interesting thing: if you look on tests with 6.3-RELEASE, 98% of sample= s is 1115322 send_sync 0 0 0 0=20 =3D send(small data) recv(small data) send(40Kb) recv(40Kb) - so every send() and recv() call is executed in <1ms. 7% of samples have=20 73629 send_sync 0 1 0 0=20=20 - so first recv() have 1ms execution time, but it's OK because it is first recv() after nanosleep(~200ms) - and we can't expect that nanosleep() will = act exactly the same on different computers. Moreover, nanosleep() period is evaluated from two local calls to clock_gettime( CLOCK_MONOTONIC, ...) and subtraction operation. But, for 10.3-RELEASE we have approximatelly even division between: 155042 send_sync 0 0 0 0 122890 send_sync 0 0 0 1 case with delay on first recv() - less then 0.02% 147 send_sync 0 1 0 0 This last 1 is for second recv() - and in this case, we have already syncronised computers over first small recv(). P.S. Test with kern.eventtimer.periodic=3D1 produce the following results f= or short test time: root@fspa2:~/clock/new_res # grep times periodic.txt | awk '{print $3 " " $= 4 " " $6 " " $8 " " $10 ;}' | sort | uniq -c 1484 send_sync 0 0 0 0 1314 send_sync 0 0 0 1 1 send_sync 0 0 0 230 4 send_sync 0 1 0 0 root@fspa1:~/clock/new_res # grep times periodic.txt | awk '{print $3 " " $= 4 " " $6 " " $8 " " $10;}' | sort | uniq -c 1698 send_sync 0 0 0 0 1134 send_sync 0 0 0 1 1 send_sync 0 0 0 229 11 send_sync 0 1 0 0 Very quick very huge delay.

The NICs in question are Broadcom BCM57840S (Supermicro AOC-STG-B4S). The link between the routers will go down on one side not long after it's brought up while staying up on the other side. I am not able to bring the link back up without either unplugging the cable or powering the routers off and on again, if I try to bring them up by taking them down and up with ifconfig they will stay down no matter what the state was before. After the routers have been up some time the console will be flooded with messages like this: bxe0: ERROR: resource (0x0) in use (status 0xffffffff bit 0x1) bxe0: ELINK EVENT LOG (3) bxe0: ELINK EVENT LOG (3) bxe0: ERROR: resource (0x0) in use (status 0xffffffff bit 0x1) bxe0: ELINK EVENT LOG (3) bxe0: ELINK EVENT LOG (3) bxe0: ERROR: resource (0x0) in use (status 0xffffffff bit 0x1) bxe0: ELINK EVENT LOG (3) bxe0: ELINK EVENT LOG (3) bxe0: ERROR: resource (0x0) in use (status 0xffffffff bit 0x1) bxe0: ELINK EVENT LOG (3) bxe0: ELINK EVENT LOG (3) bxe0: ERROR: resource (0x0) in use (status 0xffffffff bit 0x1) bxe0: ELINK EVENT LOG (3) bxe0: ELINK EVENT LOG (3) bxe0: ERROR: resource (0x0) in use (status 0xffffffff bit 0x1) bxe0: ELINK EVENT LOG (3) bxe0: ELINK EVENT LOG (3) bxe0: ERROR: resource (0x0) in use (status 0xffffffff bit 0x1) bxe0: ELINK EVENT LOG (3) bxe0: ELINK EVENT LOG (3) bxe0: ERROR: resource (0x0) in use (status 0xffffffff bit 0x1) bxe0: ELINK EVENT LOG (3) bxe0: ELINK EVENT LOG (3) bxe0: ERROR: resource (0x0) in use (status 0xffffffff bit 0x1) bxe0: ELINK EVENT LOG (3) bxe0: ELINK EVENT LOG (3) bxe0: ERROR: resource (0x0) in use (status 0xffffffff bit 0x1) bxe0: ELINK EVENT LOG (3) bxe0: ELINK EVENT LOG (3) bxe0: ERROR: resource (0x0) in use (status 0xffffffff bit 0x1) bxe0: ELINK EVENT LOG (3) bxe0: ELINK EVENT LOG (3) bxe0: ERROR: resource (0x0) in use (status 0xffffffff bit 0x1) bxe0: ELINK EVENT LOG (3) bxe0: ELINK EVENT LOG (3) bxe0: ERROR: resource (0x0) in use (status 0xffffffff bit 0x1) bxe0: ELINK EVENT LOG (3) bxe0: ELINK EVENT LOG (3) bxe0: ERROR: resource (0x0) in use (status 0xffffffff bit 0x1) bxe0: ELINK EVENT LOG (3) bxe0: ELINK EVENT LOG (3) bxe0: ERROR: resource (0x0) in use (status 0xffffffff bit 0x1) bxe0: ELINK EVENT LOG (3) bxe0: ELINK EVENT LOG (3) This is not always limited to just one interface, but can include all interfaces which are in use. -- Marius Halden From owner-freebsd-net@freebsd.org Thu Feb 1 14:56:46 2018 Return-Path: Delivered-To: freebsd-net@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 36834ED5DBE for ;

This is one of many issues we have seen with the NetXtreme II device. After a lot of back and forth (1.5 years+) with Qlogic, the issue was never sufficiently root caused. This was with the help of instrumented drivers, updated firmware, raw ASIC dumps, and hardware defect analyses of the NICs exhibiting the issue. The conclusions I've come to is that this is almost certainly not a problem with the FreeBSD driver. The condition generally persists across reboots. Often the problem would stop after the NIC was fully re-seated within the chassis, so I would definitely try that. If that doesn't work I do think the issue likely warrants an RMA of the device from Qlogic. They should have a record of the issue internally. Good luck.

It doesn't work as intended. kern.timecounter.alloweddeviation=0 might be the correct setting for the default, since nonzero gives many other suprising behaviours (like "time sleep 1" usually appearing to sleep for precisely 1 second in old versions of FreeBSD despite a large timer granularity (10 msec, the same as time(1)), while under -current it often sleeps by up to about 66 msec extra despite (actually because of) a timer granularity of 1 msec (actually much smaller, provided the caller asks for it). High resolution timers can be inefficient and are usually not needed, so FreeBSD allows inaccuracy of about 5% by default, up to an interval of about 1 second (time sleep 10 has the same absolute inaccuracy of up to about 66 msec, but that is only 0.66% relative inaccuracy). Changing kern.timecounter.alloweddeviation to 0 breaks the optimization for all uses to fix only 1 known problem here. The main bug here are probably that some TCP or application timer doesn't ask for the high resolution that it needs (I don't know how to specify the resolution for applications, and there are security problems with allowing it to be small). The timeouts are apparently long, so 5% relative is a lot absolute. I think 5% relative should only apply to short timeouts, say 10 msec instead of 1 second. kern.eventtimer.periodic=1 is never the correct setting except with buggy hardware. It turns off most of the new timer code, and breaks setting of resolutions below 1/HZ. I actually prefer simpler timeout code with only periodic timers supported, and rarely need high resolutions, but I also prefer large HZ and the new timer code works better with that provided kern.eventtimer.periodic is not 1. Periodic timers can be more efficient but this doesn't show up in my benchmarks. Since kern.eventtimer.periodic=1 seems to help, there might be further bugs, but I suspect this is an artifact of the measurements. With periodic timers, everything tends to wake up at the same time and see only constant differences in times (of an integer times the timeout period). Worse, activity between timeout interrupts tends to be invisible.
