Category: vde_switch Group: None Status: Closed Resolution: None Priority: 5 Private: No Submitted By: Michael Sallaway (sallz0r) Assigned to: Luca Bigliardi (shammash) Summary: vde_switch can't use more than 96 ports Initial Comment: When using vde_switch (most recent, 2.2.2, downloaded from here and compiled) it segfaults when setting the number of ports greater than 96, and then bringing the tap interface up. To replicate: Using command line: vde_switch -s /var/run/vde2/tap0.ctl -m 660 -p /var/run/vde2/tap0.pid -t tap0 -M /var/run/vde2/tap0.mgmt --mgmtmode 660 then issuing the vde_switch command: "port/setnumports 97" then at another terminal: "ifconfig tap0 up" causes the segfault. Probing a bit in gdb looks like it's in port.c:512 -- Program received signal SIGSEGV, Segmentation fault. 0x0804c209 in handle_in_packet (port=1, packet=0xbfec18ae, len=<value optimized out>) at port.c:512 512 BA_FORALL(vlant[vlan].bcuntag,numports, (gdb) but I couldn't quite figure out what all the macros were doing in that line. I'll have a more detailed look to see if I can figure out what it's doing... ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2012-07-21 09:08 Message: cZf8jj <a href="http://iglrrgbaswzf.com/";>iglrrgbaswzf</a>, [url=http://nbumiqphvjxj.com/]nbumiqphvjxj[/url], [link=http://uexxhxvuwbqa.com/]uexxhxvuwbqa[/link], http://vlvfzpyhvqdt.com/ ---------------------------------------------------------------------- Comment By: Luca Bigliardi (shammash) Date: 2008-09-21 06:45 Message: Hi! I've committed your patch (svn revision 321). Unfortunately I cannot reproduce what you said on IRC: "<sall> at the moment, it looks like the bug may not be completely fixed -- I can set a large number of ports fine, and it doesn't segfault anymore, but it stops transferring data, too :-(" I'm closing the bug, feel free to re-open it if you have further informations on how to reproduce the "data transfer" problem. Thank you, luca ---------------------------------------------------------------------- Comment By: Michael Sallaway (sallz0r) Date: 2008-09-19 00:56 Message: Fixed, see attachment.
