Author: hselasky

New revision: 284497
URL: https://svnweb.freebsd.org/changeset/base/284497

Log:
  MFC r280991:
  Extend fixes made in r278103 and r38754 by copying the complete packet
  header and not only partial flags and fields. Firewalls can attach
  classification tags to the outgoing mbufs which should be copied to
  all the new fragments. Else only the first fragment will be let
  through by the firewall. This can easily be tested by sending a large
  ping packet through a firewall. It was also discovered that VLAN
  related flags and fields should be copied for packets traversing
  through VLANs. This is all handled by "m_dup_pkthdr()".

  Regarding the MAC policy check in ip_fragment(), the tag provided by
  the originating mbuf is copied instead of using the default one
  provided by m_gethdr().
