ipv6 routing broken in 2.6.17-rc3,4
On my home 6to4 gw, ipv6 routing seems to be broken and everything is sent to 6to4 tunnel (the default route). It worked with fine for a long time and with 2.6.17-rc2-g4d5c34ec and it's broken with vmlinuz-2.6.17-rc3-g3cd73eed and 2.6.17-rc4-g9be2f7c3 (yesterdays kernel). Example (I add an unreachable route to an ipv6 address to force going there by ipv4 and it still uses the route): vaarikas:~# ip -6 route add unreachable 2001:7a8:1:5::14 vaarikas:~# ping6 2001:7a8:1:5::14 PING 2001:7a8:1:5::14(2001:7a8:1:5::14) 56 data bytes 64 bytes from 2001:7a8:1:5::14: icmp_seq=1 ttl=55 time=56.7 ms 64 bytes from 2001:7a8:1:5::14: icmp_seq=2 ttl=55 time=55.5 ms --- 2001:7a8:1:5::14 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 999ms rtt min/avg/max/mdev = 55.573/56.155/56.738/0.628 ms vaarikas:~# ip -6 route ::/96 via :: dev tun6to4 metric 256 expires 21332659sec mtu 1480 advmss 1420 hoplimit 4294967295 unreachable 2001:7a8:1:5::14 dev lo metric 1024 expires 21334221sec error -101 mtu 16436 advmss 16376 hoplimit 4294967295 2002:5283:297e:2::/64 dev eth0 metric 256 expires 21332659sec mtu 1500 advmss 1440 hoplimit 4294967295 2002:5283:297e::/48 dev tun6to4 metric 256 expires 21332659sec mtu 1480 advmss 1420 hoplimit 4294967295 2000::/3 via ::192.88.99.1 dev tun6to4 metric 1 expires 21332659sec mtu 1480 advmss 1420 hoplimit 4294967295 fe80::/64 dev eth0 metric 256 expires 21332650sec mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth1 metric 256 expires 21332654sec mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev tun6to4 metric 256 expires 21332659sec mtu 1480 advmss 1420 hoplimit 4294967295 ff00::/8 dev eth1 metric 256 expires 21332654sec mtu 1500 advmss 1440 hoplimit 4294967295 ff00::/8 dev tun6to4 metric 256 expires 21332659sec mtu 1480 advmss 1420 hoplimit 4294967295 ff00::/8 dev eth0 metric 256 expires 21332650sec mtu 1500 advmss 1440 hoplimit 4294967295 unreachable default dev lo proto none metric -1 error -101 hoplimit 255 Additional example: nothing goes in the direction of eth0, the packets that should go there also go to tun6to4 interface as confirmed by tcpdump.

Re: iptables broken on ppc (ptrace too?) (2.6.17-rc3)
Iptables seems to be broken on ppc for me. Kernel 2.6.17-rc3 (currently compiling rc4+git). 32-bit ppc, ARCH=ppc with PReP target. Iptables userland binary is from the latest Debian unstable (1.3.3-2). The symptoms: iptables usually just tells Invalid Argument on any modification attempt. I'm trying to set up a simple one-rule NAT for test: iptables -t nat -A POSTROUTING -s 172.30.0.0/24 -j SNAT --to 10.0.0.1 and it usually fails but has succeeded 2 times (I now have 2 rules of this kind and they seem to just wotk once set up). Trying to delete the second rule (either by replacing -A with -D or using just -D 2) gives the same error. This should already be fixed in -rc4. Unfortunately it was still there with yesterdays rc4+git. -- Meelis Roos ([EMAIL PROTECTED]) - To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

This should already be fixed in -rc4. Unfortunately it was still there with yesterdays rc4+git. I may have misinterpreted your report - are you running a 32bit or 64bit kernel? 32-bit kernel, this is a Motorola Powerstack II macine with 604e.

32-bit kernel, this is a Motorola Powerstack II macine with 604e. PReP subarch, only buildable from the old ARCH=ppc code (not yet migrated to ARCH=powerpc). Ah OK, I thought it was related to the new compat code, but that isn't the case. Your trace doesn't give much clues, except that it shows that iptables dies with a SIGSEGV, which might be a bug in userspace or in the kernel. Which was the last kernel that worked for you, and can you try that version again to rule out userspace bugs? Even worse. With yesterdays git iptable_nat loads but iptable_filter doesn't even load (Invalid argument). -- Meelis Roos ([EMAIL PROTECTED]) - To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
Re: [Bugme-new] [Bug 6613] New: iptables broken on 32-bit PReP (ARCH=ppc)
Meelis, it would really help if you could try 2.6.16 and in case that doesn't work 2.6.15 to give an idea about whether this is a recent regression or an old problem. We had a number of changes in this area in the last two kernel versions that could be related. Yes, I'm still compiling 2.6.16, since just before sending the report.

Re: Safe remote kernel install howto (Re: [Bugme-new] [Bug 6613] New: iptables broken on 32-bit PReP (ARCH=ppc))
Unfortunatlety, 2.6.15 does not boot on this machine so I'm locked out remotely at the moment. Here it my paranoid boot setup: Thanks, but it's not much use here, since the machine is a PReP powerpc machine that can boot one kernel from disk (directly loaded from boot partition, no fancy bootloader) or netboot via serial console for test kernels. However, if the test kernel hangs, it hangs and I would need remote power cycling device that I do not have. -- Meelis Roos ([EMAIL PROTECTED]) - To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

Re: [Bugme-new] [Bug 6613] New: iptables broken on 32-bit PReP (ARCH=ppc)
Very strange, this means that the initial table data must somehow be wrong, but for some reason it still seems to get past the size and offset checks for the filter table. I can't see how loading the filter table could fail after the Finished chain .. messages without another message. Which kernel version did you perform these test on?

Wrong IPv4 source address selected
This is 2.6.17-rc6 running on a 32-bit ppc (the same ARC=ppc PReP machine that had the x_tables problem, so it has the x_tables alignment first fix too).

I have seen this with ARP requests for 172.30.0.x addresses and UDP multicast traffic (avahi query from 193.40.37.61:5353 to 224.0.0.251:5353 on eth1).

Re: [PATCH] warning in SCTP
There should only be one space before the void in the patch, your email client (or something else) put another space there. Also, your email client likes to turn lines containing only spaces into empty lines, which also corrupts the patch. cg-diff file and in pine 4.61 ^R read a file. So I guess it's pine misbehaving...

Re: [PATCH] warning in SCTP
Actually, I'm backing this one out, it creates new warnings because callers of this function pass in a const pointer. OK, fair enough. Will have a look. Please test the complete build when doing warning fixes like this in the future, thanks. Sure. Evenso, I did test full make after the single compile was fine (still have it in my scrollback so here it is). So did I do anything wrong here or do we have some dependencies broken somewhere or what? Now that I read the transript again I can see that despite modifying include/net/sctp/sm.h nothing was really recompiled - should have noticed.

Re: Turn nfmark into generic mark

Re: Turn nfmark into generic mark
The mark is already a bitfield, you may dividide it into separate marks with the exception of routes which do not yet support a mask. Just checked, now that we have --and-mask and --or-mask, this is much better than before. The bitmask is OK when up to 32 marks are needed (like, for classification). But a common setup is NAT+QoS that first hides the src IP and then has to do QoS and mark is the only usable carrier of this information. So the mark value needs to carry both classification info and IP address info and here things become very limited. Though using say 8 bits for host should be usually enough... Maybe just add original src and/ord DST for carrying this information through SNAT/DNAT? Or is it too much bloat for carrying around? -- Meelis Roos ([EMAIL PROTECTED]) - To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
Re: [PATCH] IrDA: smcinit merged into smsc-ircc driver
SO This patch integrates the smcinit code into the smsc-ircc driver. SO Some laptops have their smsc-ircc chip not properly configured by the BIOS and needs some preconfiguration. Currently, this can be done from userspace with smcinit, a utility that comes with the irda-utils package. It messes with ioports and PCI settings, from userspace. SO Now with this patch, if we happen to be on one of the known to be faulty laptops, we preconfigure the chip from the driver.

ipv4 conntrack module loading broken?
Hello, I tested 2.6.23-rc1 on my prep (arch=ppc) NAT firewall. iptables loaded rules fine (simplest test was with single SNAT rule in POSTROUTING chain in nat table) and iptables -L showed the rule was loaded. But no packets matched the rule and traffic passed un-NATed (just routed). Adding LOG rules showed that no packets reach POSTROUTING at all - and no packets read PREROUTING (didn't test more). However, after loading nf_conntrack_ipv4 module by hand, the existing rules started working. Is autoloading of nf_conntrack_ipv4 broken? -- Meelis Roos ([EMAIL PROTECTED]) - To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

Re: ipv4_get_l4proto: Frag of proto 17
Yesterdays git snapsot on a normal home PC spams dmesg with the following line: ipv4_get_l4proto: Frag of proto 17 In what situation does this happen? It happens some times every hour on the average. Seems to be some UDP traffic. Firewall allows in any UDP that is ESTABLISHEFD,RELATED, DHCP (some more UDP rules with counter 0 so not important). Additionally there is internal netowkr that sometimes has a laptop but usually not and the messages have appeared also when there is nothin in the internal network. Locally mldonkey is probably using UDP, and lsof -i | grep UDP tells that named, avahi-daemon, dhcpd, chronyd, nmbd and cupsd are listening on UDP sockets (most of them on internal network).

(Evidently it worked for Meelis > before, but I dont know if that was before or after commit > 9e17f8a475). It might be related to my problem, yes (I have different kernel configs on different machines and the XFRM settings are varying at least). However, I have not succeeded in reproducing the problem at will - git checkout of another release + subsequent compile still does not trigger it. But if it is the same problem, it seems to go int triple fault or something similar for me to cause it reboot with no trace in the console. -- Meelis Roos (mr...@linux.ee)

Found one thing that changed - compiler from 6.2.0-9 to 6.2.1-5 and binutils too in debian unstable (explicitly upgraded to get fix to the binutils bug that broke 64-bit kernels). > Is it just timing and the transmit queue being busy?

4.9-rc7: (forcedeth?) BUG: sleeping function called from invalid context at kernel/irq/manage.c:110
This is 4.9-rc7 on Sun Ultra 20 (Opteron 175 on NVidia chipset PC with NVidia ethernet). BUG: sleeping function called from invalid context at kernel/irq/manage.c:110 appears twice during bootup - once during usb init when nvidia ethernet irq(?) comes in, and orher time during amd64_edac init when nv irq comes in. This is the only kernel so far after 4.8.0 that I have tested so I do not know when exactly this started.
