I've looked over sis_encap() and it seems that there is potential bug for descriptor wrap-around/shortage in bus_dmamap_load loop. After checking for necessity of m_defrag(9) it blindly assumes it has enough available Tx descriptors to send the packet. What if it sill have more fragments than currently available Tx desciptors after calling m_defrag()? Unfortunately bus_dma(9) changes for sis(4) requires real hardware and I don't have it... If I had it I would have fixed it to run it on sparc64. > Did you have/do you have any private patches in your tree? > -- Regards, Pyun YongHyeon _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
