commit 138906105dd47b9dc6b1e5010e81fc606983dd75
Author: Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>
Date:   Mon Aug 3 14:07:02 2015 +0000

    Fix release_drive on unplugged devices (pci_piix3_xen_ide_unplug)
    
    pci_piix3_xen_ide_unplug should completely unhook the unplugged
    IDEDevice from the corresponding BlockBackend, otherwise the next call
    to release_drive will try to detach the drive again.

    rtl8139: check TCP Data Offset field
    
    The TCP Data Offset field contains the length of the header.  Make sure
    it is valid and does not exceed the IP data length.

    rtl8139: skip offload on short TCP header
    
    TCP Large Segment Offload accesses the TCP header in the packet.  If the
    packet is too short we must not attempt to access header fields:
    
      tcp_header *p_tcp_hdr = (tcp_header*)(eth_payload_data + hlen);
      int tcp_hlen = TCP_HEADER_DATA_OFFSET(p_tcp_hdr);

    rtl8139: check IP Total Length field
    
    The IP Total Length field includes the IP header and data.  Make sure it

    rtl8139: check IP Header Length field
    
    The IP Header Length field was only checked in the IP checksum case, but
    is used in other cases too.

    rtl8139: skip offload on short Ethernet/IP header
    
    Transmit offload features access Ethernet and IP headers the packet.  If
    the packet is too short we must not attempt to access header fields:
    
      int proto = be16_to_cpu(*(uint16_t *)(saved_buffer + 12));

      eth_payload_data = saved_buffer + ETH_HLEN;

commit 132388208dba1c9d7fb071c39d3a5d00fec3eb1d

    rtl8139: drop tautologous if (ip) {...} statement
    
    The previous patch stopped using the ip pointer as an indicator that the
    IP header is present.  When we reach the if (ip) {...} statement we know
    ip is always non-NULL.
    
    Remove the if statement to reduce nesting.

commit 92c2288071d701e993f0b6cf6572bb95e1209017
Author: Stefan Hajnoczi <stefanha@xxxxxxxxxx>

    rtl8139: avoid nested ifs in IP header parsing
    
    Transmit offload needs to parse packet headers.  If header fields have
    unexpected values the offload processing is skipped.
    
    The code currently uses nested ifs because there is relatively little
    input validation.  The next patches will add missing input validation
    and a goto label is more appropriate to avoid deep if statement nesting.
