However, both have been obsoleted by RFC 8981. If you're open to experimentation, you can apply the patch from PR 245103 to push things further. I have always set these sysctl knobs to 1, but I only use privacy extensions on PCs and laptops - never on routers.

I'm running OPNsense on FreeBSD 14.2. I have an HP Flex IO i225 NIC install= ed in my HP Elitedesk 800 G6 Mini. Current firmware version is 1.57. I am unab= le to upgrade the nvm via nvmupdatemanager64 since the firmware is HP propriet= ary, with 1.57 being the highest available version from HP. I run the NIC at 2.5 Gbe. Under load, my speeds will drop down to around 500-600 Mb/s with large amounts of retries in iperf3. I can induce the speed drop by rapidly starting/stopping iperf transfers. I've tried everything - tunables, BIOS power settings/ASPM, AIM settings, E= EE settings. Nothing has remedied the issue. I have an identical PC with the same NIC installed, which runs Linux (Proxm= ox). The NIC in this machine does not experience any drops. This leads me to bel= ieve that the Linux drivers are able to compensate for any NIC hardware/microcode issues. The firmware of the NIC in the Linux box is also 1.57.

But to reach the call to lv_rw_owner RW_LOCK_READ has to be unset. #define lv_rw_wowner(v) \ ((v) & RW_LOCK_READ ? NULL : \ (struct thread *)RW_OWNER((v))) To me it looks as if another thread got the lock in between the if and the = call to lv_rw_owner (kgdb) bt #0 __curthread () at /usr/14-stable/sys/amd64/include/pcpu_aux.h:57 #1 doadump (textdump=3D) at /usr/14-stable/sys/kern/kern_shutdown.c:405 #2 0xffffffff805ebfcb in kern_reboot (howto=3D260) at /usr/14-stable/sys/kern/kern_shutdown.c:523 #3 0xffffffff805ec4c9 in vpanic (fmt=3D0xffffffff80a03764 "%s", ap=3Dap@entry=3D0xfffffe00109d6bb0) at /usr/14-stable/sys/kern/kern_shutdow= n.c:967 #4 0xffffffff805ec303 in panic (fmt=3D) at /usr/14-stable/sys/kern/kern_shutdown.c:891 #5 0xffffffff809a61af in trap_fatal (frame=3D, eva=3D) at /usr/14-stable/sys/amd64/amd64/trap.c:986 #6 0xffffffff809a61af in trap_pfault (frame=3D0xfffffe00109d6c30, usermode=3Dfalse, signo=3D, ucode=3D) #7 #8 __rw_wlock_hard (c=3Dc@entry=3D0xfffff8001bc27d28, v=3D)= at /usr/14-stable/sys/kern/kern_rwlock.c:1005 #9 0xffffffff80748432 in arptimer (arg=3D0xfffff8001bc27c00) at /usr/14-stable/sys/netinet/if_ether.c:212 #10 0xffffffff8060a249 in softclock_call_cc (c=3D0xfffff8001bc27cd0, cc=3Dcc@entry=3D0xffffffff81ddd0c0, direct=3Ddirect@entry=3D0) at /usr/14-stable/sys/kern/kern_timeout.c:719 #11 0xffffffff8060ba15 in softclock_thread (arg=3Darg@entry=3D0xffffffff81d= dd0c0) at /usr/14-stable/sys/kern/kern_timeout.c:858 #12 0xffffffff805a6a41 in fork_exit (callout=3D0xffffffff8060b930 , arg=3D0xffffffff81ddd0c0, frame=3D0xfffffe00109d6f40) at /usr/14-stable/sys/kern/kern_fork.c:1153 #13 #14 0xa5b2b4b2b4a3b4b2 in ??

I see what's happening here now. The if_ovpn filter function calls m_unshar= e(), which allocates a new mbuf, but then decides it doesn't want the packet aft= er all. That's normally fine, but we can't tell the caller that we've messed with t= he m pointer, so the caller continues with a now invalid mbuf pointer. I hope to propose a fix later today. --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Tue Apr 1 14:26:15 2025 X-Original-To: net@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4ZRr0724c4z5rc0f for ; Tue, 01 Apr 2025 14:26:15 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mxrelay.nyi.freebsd.org (mxrelay.nyi.freebsd.org [IPv6:2610:1c1:1:606c::19:3]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256 client-signature RSA-PSS (4096 bits) client-digest SHA256) (Client CN "mxrelay.nyi.freebsd.org", Issuer "R10" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4ZRr071f3Bz3q0m for ; Tue, 01 Apr 2025 14:26:15 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=freebsd.org; s=dkim; t=1743517575; h=from:from:reply-to:subject:subject:date:date:message-id:message-id: to:to:cc:mime-version:mime-version:content-type:content-type: content-transfer-encoding:content-transfer-encoding: in-reply-to:in-reply-to:references:references; bh=Z6oYjFjWBwS5jGU8LH/dahyPk32LH/PX+fYC0jfVwFQ=; b=CnXyqLbb6MtFlwpTuTZU6WrD8lx3EowiXOvMx3JbdT7clRKI1XDVb+lKnmX8j7O1BS/7Nd psT7R5b7utQP1oFz3YaNP6v381/VEge9iRHTqORfTL4Kdr0xN5w/OogQLs/wRq11DS77pc 0CpX1x7plYU/5tqeS1GMmc85E5OJZLUgVekPLg9/YuSrM0eDsrhirK+NNlIzPcbfCqn9AD 4LHcyQM5HEufzhb+80lzr+NC5hMidJ+f2I5rpAIUBBPBzOaHUir129kJ0lwSJlYTEPIQQd v9g7FoaAIMadRoXE2K2HY0Zm2ngxpFxeUWjZcR5D3nSZ/37oQtaJX8ehcB6ryQ== ARC-Seal: i=1; s=dkim; d=freebsd.org; t=1743517575; a=rsa-sha256; cv=none; b=vfUj1bJ1s+CvEbnAzNZuiv4ddgClXwA6kOjE0K0OLtuza/CU64hEqipyqAPu2SGMtbd3d2 PDH8+auhXvK7lfDJRNdQwehyDbI4jEXsK0LtMSJJUdB30vDhfuxROXvSjXvvaxYWw8uu8Z NiAPeswyJp8oSLt6/g0jzabjoYGBtW9QxAhYP5X1TCPta9CmVh5iNzcbmufYh8BkJ/T9rk 4SEmsiTkrVjTeAfRxcZeQSCXYbQv4RPvReJlC9U3F7foNJHxPKRiWIojGvP4AfO3qxPtsO 7vHvgCJV3i7RkpBI02mqkKOW0zjOe9GII46GhGH9LKy01zcHJIPna2VNJwHRCA== ARC-Authentication-Results: i=1; mx1.freebsd.org; none ARC-Message-Signature: i=1; a=rsa-sha256; c=relaxed/relaxed; d=freebsd.org; s=dkim; t=1743517575; h=from:from:reply-to:subject:subject:date:date:message-id:message-id: to:to:cc:mime-version:mime-version:content-type:content-type: content-transfer-encoding:content-transfer-encoding: in-reply-to:in-reply-to:references:references; bh=Z6oYjFjWBwS5jGU8LH/dahyPk32LH/PX+fYC0jfVwFQ=; b=VKRg+YQWhbcEpBc0VCPi62O+H7SAKvpmAjQLinmFfATX04+32ljYWo/LA9vlafI2Cc0a8j Yq1mjvgjDPNS2VMrwtjvJXt6+jH+ISXBsWI0LseqzdiuO5WzYwbzEdqY2yVlH8mvt/2hXE 0+QmiTvSxHP2v7mwO9rsZ0J5rdiAuvWLtsZANQ73x8/ET2gX8FGXLhg8KWFGPc95tW7rzR 3hgQZ/9Fre7TkIM3Th29BfcBlgn35/NboQJQ/F+aJF7bgBZxAZqLmliLz9o5II7+P9yfzs 34ENooWdJhdKGCw4hXn5M0NyxYG4ZUiXRywWAWf14vrTk4X+Kjljf46EEaPyAg== Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2610:1c1:1:606c::50:1d]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256) (Client did not present a certificate) by mxrelay.nyi.freebsd.org (Postfix) with ESMTPS id 4ZRr071FDczb1m for ; Tue, 01 Apr 2025 14:26:15 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org ([127.0.1.5]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id 531EQFTP081522 for ; Tue, 1 Apr 2025 14:26:15 GMT (envelope-from bugzilla-noreply@freebsd.org) Received: (from bugzilla@localhost) by kenobi.freebsd.org (8.15.2/8.15.2/Submit) id 531EQFqK081521 for net@FreeBSD.org; Tue, 1 Apr 2025 14:26:15 GMT (envelope-from bugzilla-noreply@freebsd.org) X-Authentication-Warning: kenobi.freebsd.org: bugzilla set sender to bugzilla-noreply@freebsd.org using -f From: bugzilla-noreply@freebsd.org To: net@FreeBSD.org Subject: [Bug 283426] panic in sbappendaddr_locked() - if_ovpn related?

We update the 'm' pointer in ovpn_udp_input(), but if we decide to pass on the packet (e.g. because = it's for an unknown peer) the caller (udp_append()) continues with the old 'm' pointer, eventually resulting in a use-after-free. Re-order operations in ovpn_udp_input() so that we don't modify the 'm' pointer until we're committed to keeping the packet.

If so, how are they different? Hi, Chris. From: /usr/share/doc/IPv6/IMPLEMENTATION : | As documented in the source address selection document, temporary | addresses for privacy extension are less preferred to public addresses | by default. However, for administrators who are particularly aware of | the privacy, there is a system-wide sysctl(3) variable | "net.inet6.ip6.prefer_tempaddr". When the variable is set to | non-zero, the kernel will rather prefer temporary addresses. The | default value of this variable is 0. Additionally, the files in /usr/src/sys/netinet6/ treat the value as a boolean, so it appears that in this case, 2 isn't twice as private as 1 :-) Cheers, Jamie From nobody Wed Apr 2 13:20:29 2025 X-Original-To: net@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4ZSQTn6TCyz5sH62 for ;

Use just a localhost address for a successful sendto(2). While here convert a couple checks that happen in the parent to use nor= mal ATF_REQUIRE() instead of CHILD_REQUIRE().

trunk ports may only send/receive frames with a non-zero .1q tag; hybrid ports may send/receive either type of frame. - for trunk and hybrid ports, the list of permitted VLANs may be set using +ifvlans/-ifvlans: ifconfig bridge0 +ifvlans ix0 100-599 ifconfig bridge0 -ifvlans ix0 105,300 the port will only be allowed to communicate on the VLANs in its access list (plus its PVID). - the VLAN configuration for a port is displayed in ifconfig: member: test2a flags=143 ifmaxaddr 0 port 5 priority 128 path cost 2000 pvid 1 type trunk vlans 20 - when bridging between different port types (e.g. an access port and a trunk port), the bridge will add or remove .1q tags as required. - an SVI for a particular vlan may be created on the bridge using vlan(4): ifconfig vlan20 create vlan 20 vlandev bridge0 the SVI interface will send/receive traffic for that particular VLAN. to make review a bit easier, my plan is to submit this as smaller changesets of self-contained features. to start with that's two minor bug fixes: https://github.com/freebsd/freebsd-src/pull/1639 https://github.com/freebsd/freebsd-src/pull/1637 and the first actual feature which is the ifconfig 'ifpvid' option: https://github.com/freebsd/freebsd-src/pull/1634 if anyone has any comments/questions or would like to review this (or even commit it!) do feel free - obviously, this requires a fair amount of testing and i certainly wouldn't recommend using it in production yet. this is my first time writing any non-trivial kernel code, so it's quite possible everything is completely wrong.

Thanks for working on this. Any idea what the overhead is wrt > packet forwarding rate? Any performance numbers comparing your bridge access > port feature vs vlan + bridge? i haven't done any benchmarking yet, but i don't expect any significant performance improvement; if anything it's probably the same or slightly worse, although if you're bridging a lot of VLANs, there may be some performance benefit from having 1 bridge instead of hundreds of bridges and thousands of vlan(4) interfaces. the patches do introduce a new bridge_lookup_member_if() call (which is a linked list walk of bridge members) in bridge_enqueue(), but this is only if the caller didn't already have the member pointer, which is (iirc) for dummynet traffic and some locally-originated traffic. bridge_input() already did this list walk for forwarded traffic (i.e., that was already there before my changes). i would like to avoid these calls entirely (including the existing call in bridge_input() for every packet) by replacing the if_bridge pointer in struct ifnet with a pointer to the bridge_iflist, then adding a backpointer from bridge_iflist to the bridge softc; this should mean we never need to do a list walk to forward traffic, but i need to understand the lifetime issues here first (e.g., what happens if a bridge member is removed while a packet is in a queue somewhere and will be delivered later). bridge_input() also does a second list walk in GRAB_OUR_PACKETS to find traffic destined for the local host, which we could avoid with a sysctl to ignore Ethernet traffic for MAC addresses other than the bridge itself. this would break configurations where IP addresses are assigned to bridge member interfaces, but that's always been the wrong way to configure it, so it's not a huge loss. for the VLAN filtering itself, the VLAN allow list is stored as an array of 4096 bits (64x uint64_t) which only needs a bit test for each packet, so i don't expect that to have any noticable impact on forwarding performance. if there is a performance loss, it will be from the need to fetch the bridge_iflist where we didn't need to before. but, i want to make sure the feature itself works before introducing any new bugs trying to optimise it :-) i do think there are some worthwhile performance gains to had even in the existing bridge code, though. i will at some point do a benchmark of the new code with none of the new features enabled just to make sure we don't have too much performance regression for existing setups.

charset=UTF-8; format=flowed Content-Transfer-Encoding: 7bit Hi! I have recently implemented and tested the patch at [1], which implements RFC 7217, about generating IPv6 addresses that are constant through reboots, but do not expose the MAC address of the machine, not being in any way derived by those. I'd like to get comments, testing and review for this patch, with the objective of getting approval to commit it to head once it is streamlined enough.

Hi!

I have recently implemented and tested the patch at [1], which implements RFC 7217, about generating IPv6 addresses that are constant through reboots, but do not expose the MAC address of the machine, not being in any way derived by those.

I'd like to get comments, testing and review for this patch, with the objective of getting approval to commit it to head once it is streamlined enough.

BTW I'd like to thank cognet for his suggestions and help with the patch, in particular his help in finding the correct way to implement the dad_failures counter.


And thanks in advance to anyone willing to give feedback!

This is great news for the community !

I've already started testing it on both a desktop and a laptop - which is probably even more valuable, especially since the laptop will be connecting to various networks. If I encounter any issues, I will post comments in the review.
