Device drivers are now responsible for synchronizing access to these flags, as they are in if_drv_flags.

* Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis2005-06-102-21/+20
| | | | | | | | | | | | | | | | | | | | | | | struct ifnet or the layer 2 common structure it was embedded in have been replaced with a struct ifnet pointer to be filled by a call to the new function, if_alloc(). The layer 2 common structure is also allocated via if_alloc() based on the interface type. It is hung off the new struct ifnet member, if_l2com. This change removes the size of these structures from the kernel ABI and will allow us to better manage them as interfaces come and go. Other changes of note: - Struct arpcom is no longer referenced in normal interface code. Instead the Ethernet address is accessed via the IFP2ENADDR() macro. To enforce this ac_enaddr has been renamed to _ac_enaddr. - The second argument to ether_ifattach is now always the mac address from driver private storage rather than sometimes being ac_enaddr.

* Correct mbuf packet header propagation. Previously, packet headersSam Leffler2002-12-302-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | were sometimes propagated using M_COPY_PKTHDR which actually did something between a "move" and a "copy" operation. This is replaced by M_MOVE_PKTHDR (which copies the pkthdr contents and "removes" it from the source mbuf) and m_dup_pkthdr which copies the packet header contents including any m_tag chain. This corrects numerous problems whereby mbuf tags could be lost during packet manipulations. These changes also introduce arguments to m_tag_copy and m_tag_copy_chain to specify if the tag copy work should potentially block. This introduces an incompatibility with openbsd which we may want to revisit. Note that move/dup of packet headers does not handle target mbufs that have a cluster bound to them. We may want to support this; for now we watch for it with an assert. Finally, M_COPYFLAGS was updated to include M_FIRSTFRAG|M_LASTFRAG.

| | | | | | | | | | | | | | | general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag.
