Hi, We sometimes see messages like this in dmesg and /var/log/messages in_cksum_skip: out of data by 15810 in_cksum_skip: out of data by 15810 in_cksum_skip: out of data by 15810 in_cksum_skip: out of data by 15810 in_cksum_skip: out of data by 41310 I have checked with tcpdump and these messages seems to be triggered when receiving "ICMP destination unreachable" packets. Is this a known issue in this release? Regards, Jens Kassel How-To-Repeat: "ICMP destination unreachable" packets sometimes trigger this issue but not always.
My guessing is that this messages comes off when a packet in wrong byte order enters in_cksum(). Starting with 10.0, our stack doesn't change byte order of IP packets, so if my guessing is right, the bug should vanish. We do not plan any more releases from stable/8 branch. Thus, I'd like to close the PR if you don't mind. -- Totus tuus, Glebius.
Hi, I have not tested this on FreeBSD 10. But I found that the problem can only be reproduced when using the bce driver. Tested with both re & bge drivers and with these the problem cannot be reproduced. Checked SVN history for bce but could not find any commit that seemed to be related to this issue. Regards, Jens
If memory serves me well, that were panics with bce(4) and wrong byte order, that urged me to make byte order stable throughout the network stack. However, we didn't find any special in the driver itself after all. It might have a bug, but it also might just exposed a bug in the stack. -- Totus tuus, Glebius.
batch change: For bugs that match the following - Status Is In progress AND - Untouched since 2018-01-01. AND - Affects Base System OR Documentation DO: Reset to open status. Note: I did a quick pass but if you are getting this email it might be worthwhile to double check to see if this bug ought to be closed.
Believed to be fixed in all supported branches.
