This fixes the "[pmc,X] negative increment" assertion on the context switch when clipped counter value is sign-extended. Add definitions for the MSR IA32_PERF_CAPABILITIES needed to detect the feature.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=207068 --- Comment #12 from Konstantin Belousov --- (In reply to Konstantin Belousov from comment #7) I still not able to reproduce the problem, not on sandy machine, not on the haswell box. Even more strange, sandy box does not report any counter increment for ,usr. Anyway, I do believe that your patch is the right thing to do, I committed it split into main part and two tweaks. -- You are receiving this mail because: You are on the CC list for the bug. ___ freebsd-amd64@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-amd64 To unsubscribe, send any mail to "freebsd-amd64-unsubscr...@freebsd.org"
[Bug 207087] kernel: r295285 in 10.2-STABLE breaks OpenVPN functionality
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=207087 --- Comment #14 from George V. Neville-Neil --- Thanks for all the updates, this does help to track some of this down. A few more questions: If you are not using an Android client does everything just work? In your last test did you also turn off IPSEC and just use IPFW? Can I see the IPFW ruleset you're using? And, can I get a full pcap file rather than a text dump of the attempted session? -- You are receiving this mail because: You are on the CC list for the bug. ___ freebsd-amd64@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-amd64 To unsubscribe, send any mail to "freebsd-amd64-unsubscr...@freebsd.org"
[Bug 207085] pmc assertion failure: pmc %p non-NULL
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=207085 Konstantin Belousov changed: What|Removed |Added CC||k...@freebsd.org --- Comment #1 from Konstantin Belousov --- (In reply to joss.upton from comment #0) So the question is how could pc_corepmcs[idx].phw_pmc become non-NULL legitimately there ? Context switch hooks should manage cpu slots, so I see at least two possibilities: - cpu != curcpu and something else context-switched on cpu which brought its process-private pcms - global pcm was activated which took the slot. In fact, this is unlikely since sx lock is still owned. Could you look what pcm was in the slot for fired assert, and who is the owner of it ? -- You are receiving this mail because: You are on the CC list for the bug. ___ freebsd-amd64@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-amd64 To unsubscribe, send any mail to "freebsd-amd64-unsubscr...@freebsd.org"

[Bug 207080] pfctl crash when load pf.conf, libc/resolv problem ?
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=207080 Kristof Provost changed: What|Removed |Added CC||k...@freebsd.org --- Comment #1 from Kristof Provost --- I've had a quick look at this, and I think there are two problems. The first is 'pfctl: failed to create table __automatic_4130873d_220 in : Cannot allocate memory'. For some reason the kernel is unable to create this table. That might be simple memory pressure (i.e. a combination of memory use and memory fragmentation). The second is the crash of pfctl. That looks like heap corruption as a result of incorrect handling of the error from the kernel. For that one rebuilding world with 'DEBUG_FLAGS=-g' and running pfctl in valgrind is quite useful. I've had a quick test on 10 as well, and I've been unable to reproduce the problem there. -- You are receiving this mail because: You are on the CC list for the bug. ___ freebsd-amd64@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-amd64 To unsubscribe, send any mail to "freebsd-amd64-unsubscr...@freebsd.org"
