Whether the reaction from the FreeBSD side is= OK not not depends on SEG.SEQ of the received ACK segments. Unfortunately, tcp= dump doesn't how SEG.SEQ for the ACK segments. Please note that https://tools.ietf.org/html/rfc793#section-3.9, page 69, specifies the conditions under which a received TCP segment is acceptable. = If the received ACK is not acceptable (this depends on SEG.SEQ), an ACK as the= one being sent has to be sent. So seeing the SEG.SEQ of the ACK segments is crucial here. --=20 You are receiving this mail because: You are the assignee for the bug.= From owner-freebsd-net@freebsd.org Sun Nov 18 20:02:47 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 771E1110DD86 for ; Sun, 18 Nov 2018 20:02:47 +0000 (UTC) (envelope-from hausen@punkt.de) Received: from kagate.punkt.de (kagate.punkt.de [217.29.33.131]) (using TLSv1.2 with cipher DHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mx1.freebsd.org (Postfix) with ESMTPS id 5AF446DA6A for ; Sun, 18 Nov 2018 20:02:41 +0000 (UTC) (envelope-from hausen@punkt.de) Received: from hugo10.ka.punkt.de (hugo10.ka.punkt.de [217.29.44.10]) by gate1.intern.punkt.de with ESMTP id wAIK2XB6023540 for ; Sun, 18 Nov 2018 21:02:33 +0100 (CET) Received: from [217.29.46.123] ([217.29.46.123]) by hugo10.ka.punkt.de (8.14.2/8.14.2) with ESMTP id wAIK2X69092669 for ; Sun, 18 Nov 2018 21:02:33 +0100 (CET) (envelope-from hausen@punkt.de) From: "Patrick M.

Zeeb changed: What |Removed |Added ---------------------------------------------------------------------------- Severity|Affects Many People |Affects Some People CC| |bz@FreeBSD.org Assignee|bugs@FreeBSD.org |net@FreeBSD.org --- Comment #4 from Bjoern A. Zeeb --- (In reply to peos42 from comment #0) I used to have such a setup with a very well known European hoster. It's idiotic IPv4 behaviour (and was exactly that there as well) and it'll eventually cause them a lot of trouble in IPv6 land as their neighbour tabl= es on the L2/3 device in front of you can easily fill up. My European one aft= er 1.5 years of silence has just updated and rolled out the new setup with a transition period years after. They never said anything but I was happy th= ey listened. The solution for any hoster is to have a fe80::1/64 as a default gateway on= all interfaces for all customers. It's a link-local address, there'll not be t= oo many of them and then, given they know the ether address of their customers route whatever network their customers get to that; no extra neighbour table addresses; their router is a lot less attackable as there's no public /64 on each interface, etc. So much more to say about all this but that's their problem and not yours. You can still make this work with FreeBSD and some "glue" and magic and I'll just braindump here what comes to my mind: (a) set your ipv6_default_interface to your external interface (b) look at ndp -an to find your routers link-local address and then set ipv6_defaultrouter=3D"fe80:....%${ipv6_default_interface}" Note this is a hack as that address can change if your hoster changes things or moves the VM around; in a more or less static setups it works; it could be "automated"; (c) I wonder if ping6 -n ff02::2% will give you answers, that sh= ould be the same address as in (b). If the address from (b) changes you might be out of luck and the best you could do is to script a "checker" which valida= tes the address every minute and updates the IPv6 default route accordingly. (d) The above assumes that calling rtsol on the interface doesn't help you = in that setup. Would be great if it would. (e) alternatively: you might be able to set the default gateway using -link= ;=20 can't remember if that works; haven't tried that in years. Try and see if you can work it out from there. I'd be curious to hear... --=20 You are receiving this mail because: You are the assignee for the bug.= From owner-freebsd-net@freebsd.org Mon Nov 19 08:32:32 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 826431138B75 for ; Mon, 19 Nov 2018 08:32:32 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mailman.ysv.freebsd.org (mailman.ysv.freebsd.org [IPv6:2001:1900:2254:206a::50:5]) by mx1.freebsd.org (Postfix) with ESMTP id 1ABF96B49A for ; Mon, 19 Nov 2018 08:32:32 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: by mailman.ysv.freebsd.org (Postfix) id D226E1138B74; Mon, 19 Nov 2018 08:32:31 +0000 (UTC) Delivered-To: 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 AA8BA1138B73 for ; Mon, 19 Nov 2018 08:32:31 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mxrelay.ysv.freebsd.org (mxrelay.ysv.freebsd.org [IPv6:2001:1900:2254:206a::19:3]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits)) (Client CN "mxrelay.ysv.freebsd.org", Issuer "Let's Encrypt Authority X3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 37B5A6B499 for ; Mon, 19 Nov 2018 08:32:31 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2001:1900:2254:206a::16:76]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mxrelay.ysv.freebsd.org (Postfix) with ESMTPS id 7AEC9312B for ; Mon, 19 Nov 2018 08:32:30 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org ([127.0.1.118]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id wAJ8WUtF044006 for ; Mon, 19 Nov 2018 08:32:30 GMT (envelope-from bugzilla-noreply@freebsd.org) Received: (from www@localhost) by kenobi.freebsd.org (8.15.2/8.15.2/Submit) id wAJ8WU9e044005 for net@FreeBSD.org; Mon, 19 Nov 2018 08:32:30 GMT (envelope-from bugzilla-noreply@freebsd.org) X-Authentication-Warning: kenobi.freebsd.org: www set sender to bugzilla-noreply@freebsd.org using -f From: bugzilla-noreply@freebsd.org To: net@FreeBSD.org Subject: [Bug 200319] Bridge+CARP crashes/freezes Date: Mon, 19 Nov 2018 08:31:37 +0000 X-Bugzilla-Reason: AssignedTo X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: kern X-Bugzilla-Version: 10.1-RELEASE X-Bugzilla-Keywords: crash, needs-qa X-Bugzilla-Severity: Affects Many People X-Bugzilla-Who: koobs@FreeBSD.org X-Bugzilla-Status: Open X-Bugzilla-Resolution: X-Bugzilla-Priority: Normal X-Bugzilla-Assigned-To: net@FreeBSD.org X-Bugzilla-Flags: mfc-stable11? mfc-stable12?

Elsukov --- I saw that Sepherosa has added support of non-prefix directly reachable rou= tes to DragonflyBSD. Also I saw several times in the our mailing lists the ques= tion why such routes don not work on FreeBSD without properly configured prefixe= s. Maybe it is time to rethink this and add such support? The noted commits are https://gitweb.dragonflybsd.org/dragonfly.git/commitdiff/4957d64ac9c5d91441= 4e533e7da909f8162b7973 https://gitweb.dragonflybsd.org/dragonfly.git/commitdiff/b72db1d3321d7a80f4= da3f727765bcc200f30278 But FreeBSD needs a bit more changes. --=20 You are receiving this mail because: You are the assignee for the bug.= From owner-freebsd-net@freebsd.org Mon Nov 19 11:22:24 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 9DDE5113CCAC for ;

The procedure that I describe in the previous post crashes consistently, wh= ich is a good point to start debugging. I suspect the crash to come from intern= al structures that are left corrupted at some point, after which there are sev= eral symptoms, like cannot intuit interface, no memory allocated, and ultimately= a kernel crash. I have compiled a new kernel with DDB support enabled, hopping to be able to inspect memory at runtime, but the address of the (struct rtentry *) is different each time.

I've set an alias of 127.0.0.2 to interface lo0 then set dnscrypt-proxy to run on the address. Then I've added the following lines to dhclient.conf: ``` # /etc/dhclient.conf # dnscrypt-proxy2 prepend domain-name-servers 127.0.0.2; # Backups append domain-name-servers 1.1.1.1, 1.0.0.1; ``` I expected the above addition yield the following in resolv.conf: ``` search some-search-domain.com nameserver 127.0.0.2 nameserver [SOME_DHCP_SERVER_SET_DNS_IP1_HERE] nameserver [SOME_DHCP_SERVER_SET_DNS_IP2_HERE] nameserver 1.1.1.1 nameserver 1.0.0.1 ``` However, the actual result is that the dhclient completely ignored the prepend option: ``` search some-search-domain.com nameserver [SOME_DHCP_SERVER_SET_DNS_IP1_HERE] nameserver [SOME_DHCP_SERVER_SET_DNS_IP2_HERE] nameserver 1.1.1.1 nameserver 1.0.0.1 ``` Are the prepend and append options mutually exclusive or are they working in a last-to-appear-wins manner? I couldn't find this behavior being mentioned in any of the man pages. Any lead would be appreciated.

Router Advertisements contain a list of prefixes used for on-link determination and/or autonomous address configuration; flags associated with the prefixes specify the intended uses of a particular prefix. Hosts use the advertised on-link prefixes to build and maintain a list that is used in deciding when a packet's destination is on-link or beyond a router. So far, so good. Note that a destination can be on-link even though it is not covered by any advertised on- link prefix. In such cases, a router can send a Redirect informing the sender that the destination is a neighbor.

Besides, I don't see any relevance of the source address selection of outgo= ing NS to this issue. The problem description is a bit unclear, but I don't see anything in the FreeBSD's implementation that may be related to this trouble and is not RFC-compliant.

Such route can by added by administrator. The main user's complain is that = for IPv4 you can add route like `route add -host A.B.C.D -iface em0`, but for I= Pv6 this won't work, because you need to have configured prefix on the interfac= e, without the prefix ND6 will think that address on this link is not neighbor, and won't send NS, and you will get ENOBUFS error when try to send a packet= to specified host. This patch adds the check and now the kernel at least will = try to resolve address on the interface. So, in general you are able to add on-link route to your gateway like this: route -6 add -host fd00::1 -iface em0 --=20 You are receiving this mail because: You are the assignee for the bug.= From owner-freebsd-net@freebsd.org Wed Nov 21 11:18:07 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 31CBF113485D for ; Wed, 21 Nov 2018 11:18:07 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mailman.ysv.freebsd.org (mailman.ysv.freebsd.org [IPv6:2001:1900:2254:206a::50:5]) by mx1.freebsd.org (Postfix) with ESMTP id BD69D7ABBA for ; Wed, 21 Nov 2018 11:18:06 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: by mailman.ysv.freebsd.org (Postfix) id 7ADCB113485A; Wed, 21 Nov 2018 11:18:06 +0000 (UTC) Delivered-To: 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 694C31134858 for ; Wed, 21 Nov 2018 11:18:06 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mxrelay.ysv.freebsd.org (mxrelay.ysv.freebsd.org [IPv6:2001:1900:2254:206a::19:3]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits)) (Client CN "mxrelay.ysv.freebsd.org", Issuer "Let's Encrypt Authority X3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 093187ABB7 for ; Wed, 21 Nov 2018 11:18:06 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2001:1900:2254:206a::16:76]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mxrelay.ysv.freebsd.org (Postfix) with ESMTPS id 3B9E51D78C for ; Wed, 21 Nov 2018 11:18:05 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org ([127.0.1.118]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id wALBI5BP053876 for ; Wed, 21 Nov 2018 11:18:05 GMT (envelope-from bugzilla-noreply@freebsd.org) Received: (from www@localhost) by kenobi.freebsd.org (8.15.2/8.15.2/Submit) id wALBI5A7053875 for net@FreeBSD.org; Wed, 21 Nov 2018 11:18:05 GMT (envelope-from bugzilla-noreply@freebsd.org) X-Authentication-Warning: kenobi.freebsd.org: www set sender to bugzilla-noreply@freebsd.org using -f From: bugzilla-noreply@freebsd.org To: net@FreeBSD.org Subject: [Bug 200319] Bridge+CARP crashes/freezes Date: Wed, 21 Nov 2018 11:18:03 +0000 X-Bugzilla-Reason: AssignedTo X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: kern X-Bugzilla-Version: 10.1-RELEASE X-Bugzilla-Keywords: crash, needs-qa X-Bugzilla-Severity: Affects Many People X-Bugzilla-Who: loos@FreeBSD.org X-Bugzilla-Status: Open X-Bugzilla-Resolution: X-Bugzilla-Priority: Normal X-Bugzilla-Assigned-To: net@FreeBSD.org X-Bugzilla-Flags: mfc-stable11? mfc-stable12?

But access to rt_ifp->if_addr is not easy to protect= in stable/11. The problem happens due to interface is destroying in the time, = when we are doing iteration through routes. And even if you add NULL check here, there is not any guarantee that you won't make access to already freed memo= ry in the rtsock_msg_buffer() a bit later, when you will make access to info.rti_info[]. Also I think an application may expect presence of both RTAX_IFP and RTAX_IFA pointers. --=20 You are receiving this mail because: You are the assignee for the bug.= From owner-freebsd-net@freebsd.org Thu Nov 22 06:32:53 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 57BCA113B55C for ; Thu, 22 Nov 2018 06:32:53 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mailman.ysv.freebsd.org (mailman.ysv.freebsd.org [IPv6:2001:1900:2254:206a::50:5]) by mx1.freebsd.org (Postfix) with ESMTP id E50D08DA6C for ; Thu, 22 Nov 2018 06:32:52 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: by mailman.ysv.freebsd.org (Postfix) id A8392113B55A; Thu, 22 Nov 2018 06:32:52 +0000 (UTC) Delivered-To: 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 954E4113B559 for ; Thu, 22 Nov 2018 06:32:52 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mxrelay.ysv.freebsd.org (mxrelay.ysv.freebsd.org [IPv6:2001:1900:2254:206a::19:3]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits)) (Client CN "mxrelay.ysv.freebsd.org", Issuer "Let's Encrypt Authority X3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 302BF8DA65 for ; Thu, 22 Nov 2018 06:32:52 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2001:1900:2254:206a::16:76]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mxrelay.ysv.freebsd.org (Postfix) with ESMTPS id 624FD7A04 for ; Thu, 22 Nov 2018 06:32:51 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org ([127.0.1.118]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id wAM6Wpda013739 for ; Thu, 22 Nov 2018 06:32:51 GMT (envelope-from bugzilla-noreply@freebsd.org) Received: (from www@localhost) by kenobi.freebsd.org (8.15.2/8.15.2/Submit) id wAM6WpdT013738 for net@FreeBSD.org; Thu, 22 Nov 2018 06:32:51 GMT (envelope-from bugzilla-noreply@freebsd.org) X-Authentication-Warning: kenobi.freebsd.org: www set sender to bugzilla-noreply@freebsd.org using -f From: bugzilla-noreply@freebsd.org To: net@FreeBSD.org Subject: [Bug 230498] Fatal trap 12: page fault while in kernel mode in sysctl_dumpentry from sysctl NET_RT_DUMP Date: Thu, 22 Nov 2018 06:32:50 +0000 X-Bugzilla-Reason: AssignedTo X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: kern X-Bugzilla-Version: 11.2-STABLE X-Bugzilla-Keywords: X-Bugzilla-Severity: Affects Some People X-Bugzilla-Who: ae@FreeBSD.org X-Bugzilla-Status: New X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: net@FreeBSD.org X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: https://bugs.freebsd.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-Rspamd-Queue-Id: E50D08DA6C X-Spamd-Result: default: False [0.71 / 15.00]; local_wl_from(0.00)[freebsd.org]; NEURAL_HAM_SHORT(-0.07)[-0.065,0]; NEURAL_SPAM_LONG(0.42)[0.416,0]; NEURAL_SPAM_MEDIUM(0.36)[0.355,0]; ASN(0.00)[asn:10310, ipnet:2001:1900:2254::/48, country:US] X-Rspamd-Server: mx1.freebsd.org X-BeenThere: freebsd-net@freebsd.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: Networking and TCP/IP with FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 22 Nov 2018 06:32:53 -0000 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D230498 --- Comment #14 from Andrey V.

I would like to clarify situation with jumbo frames in ixgbe driver. I've looked to https://github.com/luigirizzo/netmap/blob/master/LINUX/ixgbe_netmap_linux.h and see a lot of changes compared 11/12-STABLE version ixgbe_netmap.h. Is it possible to back port it?

In particular, on Linux jumbo frames are already supported on ixgbe, e1000, igb, e1000e, etc. I have some netmap patches are already in the queue (see here https://reviews.freebsd.org/differential/query/Ol8MNtAi2AIs/#R), so I can address the ixgbe-jumbo-frames item as soon as the queue drains. If you want to give a try in the meanwhile, and/or test ixgbe on FreeBSD it would be great.

Use IFNET_RLOCK_NOSLEEP() to protect from interface destroying during routes iteration. In if_detach_internal() mark interface as dying just after we re= move it from the ifnets list. In sysctl_dumpentry() add the check, that interface was not destroyed before doing the access. --=20 You are receiving this mail because: You are the assignee for the bug.= From owner-freebsd-net@freebsd.org Thu Nov 22 14:22:22 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 D60121149D15 for ; Thu, 22 Nov 2018 14:22:22 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mailman.ysv.freebsd.org (mailman.ysv.freebsd.org [IPv6:2001:1900:2254:206a::50:5]) by mx1.freebsd.org (Postfix) with ESMTP id 6CF6B7888B for ; Thu, 22 Nov 2018 14:22:22 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: by mailman.ysv.freebsd.org (Postfix) id 308671149D14; Thu, 22 Nov 2018 14:22:22 +0000 (UTC) Delivered-To: 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 1ED9C1149D13 for ; Thu, 22 Nov 2018 14:22:22 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mxrelay.ysv.freebsd.org (mxrelay.ysv.freebsd.org [IPv6:2001:1900:2254:206a::19:3]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits)) (Client CN "mxrelay.ysv.freebsd.org", Issuer "Let's Encrypt Authority X3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id B076978881 for ; Thu, 22 Nov 2018 14:22:21 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2001:1900:2254:206a::16:76]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mxrelay.ysv.freebsd.org (Postfix) with ESMTPS id CCD05BA2D for ; Thu, 22 Nov 2018 14:22:20 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org ([127.0.1.118]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id wAMEMKdP096355 for ; Thu, 22 Nov 2018 14:22:20 GMT (envelope-from bugzilla-noreply@freebsd.org) Received: (from www@localhost) by kenobi.freebsd.org (8.15.2/8.15.2/Submit) id wAMEMK7o096354 for net@FreeBSD.org; Thu, 22 Nov 2018 14:22:20 GMT (envelope-from bugzilla-noreply@freebsd.org) X-Authentication-Warning: kenobi.freebsd.org: www set sender to bugzilla-noreply@freebsd.org using -f From: bugzilla-noreply@freebsd.org To: net@FreeBSD.org Subject: [Bug 230498] Fatal trap 12: page fault while in kernel mode in sysctl_dumpentry from sysctl NET_RT_DUMP Date: Thu, 22 Nov 2018 14:22:20 +0000 X-Bugzilla-Reason: AssignedTo X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: kern X-Bugzilla-Version: 11.2-STABLE X-Bugzilla-Keywords: X-Bugzilla-Severity: Affects Some People X-Bugzilla-Who: ae@FreeBSD.org X-Bugzilla-Status: New X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: net@FreeBSD.org X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: attachments.isobsolete attachments.created Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: https://bugs.freebsd.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-Rspamd-Queue-Id: 6CF6B7888B X-Spamd-Result: default: False [1.57 / 15.00]; local_wl_from(0.00)[freebsd.org]; NEURAL_SPAM_LONG(0.40)[0.397,0]; NEURAL_SPAM_MEDIUM(0.33)[0.327,0]; ASN(0.00)[asn:10310, ipnet:2001:1900:2254::/48, country:US]; NEURAL_SPAM_SHORT(0.85)[0.848,0] X-Rspamd-Server: mx1.freebsd.org X-BeenThere: freebsd-net@freebsd.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: Networking and TCP/IP with FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 22 Nov 2018 14:22:23 -0000 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D230498 Andrey V.

Do I have any chances to get netmap supported (maybe, not very efficient) on this NIC? --=20 // Lev Serebryakov --VMyH4QgKsUYNQLeSuXCaPCWur1Cbd2rqq-- --kgGYPquZi7NoGRbw0W0ZUQqsqkSGLPcYk Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEE+W0coLX0MYtnSzMK6rA8WL/cR48FAlv2y5RfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldEY5 NkQxQ0EwQjVGNDMxOEI2NzRCMzMwQUVBQjAzQzU4QkZEQzQ3OEYACgkQ6rA8WL/c R4922g/+M+x8uzxfzUDShXMAvimi+SwGkY9SUl4Tjx3VXADlxpBpX182+hadSa1/ N+OtR1QQmgb6K5tH/mUJJE3RAGdJyEz/LGE5tPPtDXMS1FAhkOC8oKnFIfM/4vsf 9BcQxMTwgIkRUNixJ39WYqRKsQG9LEBBsCzXLlhMSJErS+Hnw/9yx/Q45jWXaOJt 962ZxZsrNmw2z/cNk9KQg0Ae7pNciq31zy8Lu+MlZo60vEmzrVfC+p3520jBCAAQ jNacVIDa14U9TD2gklfwqFq/LX9jX39oBKx00g4fLhxwm6yJpOjC5cSROBWFR4zG Iqxoz+yma898q9SXXyBVhoQ2NmXtgdWupq/qg/eDgjk1VwiP6CkB3xR1Al8brWA3 z9JzT3UUIiFNZ2CqozybJLZcg5iTmI99U6XvWvGAp2preTHVdCKlsqc+mNlbHFir 49wmKg3ePCo067V1s7diQDVrMe+PS7d2HnPsFWPImSpxldh3mr7dPFqufzhD8yf7 wBIvle8SLkUGW5R+yXl5tPfM4o5/SPaboWaT3BOcO6MHCE6+bGdtMpton2jytkU2 yihm4PX3NeZ+a8CsJrdPW/5t2CA8b7x7713zQmBwbMecrctm8GLraFXg18mZb2DA YckHaASjOq2r8hB8Mhpsjcxa+s7MUqzDXMyT9F7jCVC62KJxDe0= =uSWH -----END PGP SIGNATURE----- --kgGYPquZi7NoGRbw0W0ZUQqsqkSGLPcYk-- From owner-freebsd-net@freebsd.org Fri Nov 23 09:16:42 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 725AD11405D4 for ; Fri, 23 Nov 2018 09:16:42 +0000 (UTC) (envelope-from v.maffione@gmail.com) Received: from mail-qk1-x744.google.com (mail-qk1-x744.google.com [IPv6:2607:f8b0:4864:20::744]) (using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)) (Client CN "smtp.gmail.com", Issuer "Google Internet Authority G3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id C01A67E5DB for ; Fri, 23 Nov 2018 09:16:41 +0000 (UTC) (envelope-from v.maffione@gmail.com) Received: by mail-qk1-x744.google.com with SMTP id o125so8164564qkf.3 for ; Fri, 23 Nov 2018 01:16:41 -0800 (PST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20161025; h=mime-version:references:in-reply-to:from:date:message-id:subject:to :cc; bh=bxp4XiaPcGdTKl0yGw+xxAgooeZJcXGkcHchxMrYntA=; b=aE5InNakjZoy8AnEmQVzObPhzlq1mYRohMzJ/Nxv2OMe6HnpLrcI9InsSWhqDSt5ti O2mLX5DiR9MVAkhe1hxxJOdOX/xviHdy2Litdrla5ym3YqTlC1/g7+YKCwv/y+hfQPWg S31B5D6+auaobbp48HbNcrwPYtbfbP2WA2qq5g3Wd05AkKg/OW1q33XMxfpvJDbLK0lt sKomBm1y8wrIMh2O0J9ch08vXijaap+draL3/LyFrLSMUelVgF3Z7opU7BDwQ5FBrwhw 8rrbC85DHNukMF2f84LtLEDoN/Ov0YdNh3TTSI3YH1PWMh2qGT5PDjRZS1ohkQZEek8T GbnQ== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20161025; h=x-gm-message-state:mime-version:references:in-reply-to:from:date :message-id:subject:to:cc; bh=bxp4XiaPcGdTKl0yGw+xxAgooeZJcXGkcHchxMrYntA=; b=MoiBlIVRprt4YiicQyJ6oeaGXSWHV9QQ4KwKHR1O0dOve1MTKrYvMJ+gMPRM8qmTbe JQeEwaY238Jpx2x24AP5YjcPqAdvCRRTy5gfpK83w57RbkwiPHHZV9MBO4seoizlC45M FxE8PHjSb1j9lURXOd08tAATHUXZKvf2ekQ761qnhAlavUTgtpjuXJ4IgU1mZdGtyx20 hU2fTzaexeYDDbHrHEdA8zWy3wUjtrbcY6FZJ5xIGfA8dIxV2T6cKjqLni+sMkB7RPKs 2Mqx5TglTSPFa2KSHNP3RtdZYrIICAL5mIosFJhbx2ekCg+LVXZK444YdbqxY2LWhWwV 4mMg== X-Gm-Message-State: AA+aEWZY/GZ1bst1xM9iZyVJZoq6W2DL23xsD1dlJx3I01kZM82u7382 M0VtUkfPrLDoTvcEjXiRMg0RFX/nzvzFKo4Tk0hLNA== X-Google-Smtp-Source: AFSGD/Wy7c9VCsxvHF526ubLbjhDEP8/oNfTtOEwQS2vCqqwlVVLbXviFr6Wipl6Qd1ywAwYx0NCHw+HexpMOuhqzmU= X-Received: by 2002:a37:b581:: with SMTP id e123mr12783020qkf.183.1542964601138; Fri, 23 Nov 2018 01:16:41 -0800 (PST) MIME-Version: 1.0 References: <5756C17D.1090409@yandex.ru> <1502708678.10983095.1465385308094.JavaMail.zimbra@ulg.ac.be> In-Reply-To: From: Vincenzo Maffione Date: Fri, 23 Nov 2018 10:16:28 +0100 Message-ID: Subject: Re: Is netmap jumbo frames broken in STABLE?
