/*
|
|
* OS dependencies:
|
|
*
|
|
* - struct rt_addrinfo
|
|
* all *BSDs except bsdi4 only have two members; rti_addrs and rti_info[].
|
|
* bsdi4 has additional members; rti_flags, rti_ifa, rti_ifp, and rti_rtm.
|
|
*
|
|
* - side effects of rtrequest[1](RTM_DELETE)
|
|
* BSDI[34]: delete all cloned routes underneath the route.
|
|
* FreeBSD[234]: delete all protocol-cloned routes underneath the route.
|
|
* note that cloned routes from an interface direct route
|
|
* still remain.
|
|
* NetBSD, OpenBSD: no side effects.
|
|
* - privileged process
|
|
* NetBSD, FreeBSD 3
|
|
* struct proc *p;
|
|
* if (p && !suser(p->p_ucred, &p->p_acflag))
|
|
* privileged;
|
|
* FreeBSD 4
|
|
* struct proc *p;
|
|
* if (p && !suser(p))
|
|
* privileged;
|
|
* OpenBSD, BSDI [34], FreeBSD 2
|
|
* struct socket *so;
|
|
* if (so->so_state & SS_PRIV)
|
|
* privileged;
|
|
* - foo_control
|
|
* NetBSD, FreeBSD 3
|
|
* needs to give struct proc * as argument
|
|
* OpenBSD, BSDI [34], FreeBSD 2
|
|
* do not need struct proc *
|
|
* - bpf:
|
|
* OpenBSD, NetBSD, BSDI [34]
|
|
* need caddr_t * (= if_bpf **) and struct ifnet *
|
|
* FreeBSD 2, FreeBSD 3
|
|
* need only struct ifnet * as argument
|
|
* - struct ifnet
|
|
* use queue.h? member names if name
|
|
* --- --- ---
|
|
* FreeBSD 2 no old standard if_name+unit
|
|
* FreeBSD 3 yes strange if_name+unit
|
|
* OpenBSD yes standard if_xname
|
|
* NetBSD yes standard if_xname
|
|
* BSDI [34] no old standard if_name+unit
|
|
* - usrreq
|
|
* NetBSD, OpenBSD, BSDI [34], FreeBSD 2
|
|
* single function with PRU_xx, arguments are mbuf
|
|
* FreeBSD 3
|
|
* separates functions, non-mbuf arguments
|
|
* - {set,get}sockopt
|
|
* NetBSD, OpenBSD, BSDI [34], FreeBSD 2
|
|
* manipulation based on mbuf
|
|
* FreeBSD 3
|
|
* non-mbuf manipulation using sooptcopy{in,out}()
|
|
* - timeout() and untimeout()
|
|
* NetBSD, OpenBSD, BSDI [34], FreeBSD 2
|
|
* timeout() is a void function
|
|
* FreeBSD 3
|
|
* timeout() is non-void, must keep returned value for untimeout()
|
|
* - sysctl
|
|
* NetBSD, OpenBSD
|
|
* foo_sysctl()
|
|
* BSDI [34]
|
|
* foo_sysctl() but with different style
|
|
* FreeBSD 2, FreeBSD 3
|
|
* linker hack
|
|
*
|
|
* - if_ioctl
|
|
* NetBSD, FreeBSD 3, BSDI [34]
|
|
* 2nd argument is u_long cmd
|
|
* FreeBSD 2
|
|
* 2nd argument is int cmd
|
|
* - if attach routines
|
|
* NetBSD
|
|
* void xxattach(int);
|
|
* FreeBSD 2, FreeBSD 3
|
|
* void xxattach(void *);
|
|
* PSEUDO_SET(xxattach, if_xx);
|
|
*
|
|
* - ovbcopy()
|
|
* in NetBSD 1.4 or later, ovbcopy() is not supplied in the kernel.
|
|
* bcopy() is safe against overwrites.
|
|
* - splnet()
|
|
* NetBSD 1.4 or later requires splsoftnet().
|
|
* other operating systems use splnet().
|
|
*
|
|
* - dtom()
|
|
* NEVER USE IT!
|
|
*
|
|
* - struct ifnet for loopback interface
|
|
* BSDI3: struct ifnet loif;
|
|
* BSDI4: struct ifnet *loifp;
|
|
* NetBSD, OpenBSD, FreeBSD2: struct ifnet loif[NLOOP];
|
|
*
|
|
* odd thing is that many of them refers loif as ifnet *loif,
|
|
* not loif[NLOOP], from outside of if_loop.c.
|
|
*
|
|
* - number of bpf pseudo devices
|
|
* others: bpfilter.h, NBPFILTER
|
|
* FreeBSD4: bpf.h, NBPF
|
|
* solution:
|
|
* #if defined(__FreeBSD__) && __FreeBSD__ >= 4
|
|
* #include "bpf.h"
|
|
* #define NBPFILTER NBPF
|
|
* #else
|
|
* #include "bpfilter.h"
|
|
* #endif
|
|
*
|
|
* - protosw for IPv4 (sys/netinet)
|
|
* FreeBSD4: struct ipprotosw in netinet/ipprotosw.h
|
|
* others: struct protosw in sys/protosw.h
|
|
*
|
|
* - header files with defopt (opt_xx.h)
|
|
* FreeBSD3: opt_{inet,ipsec,ip6fw,altq}.h
|
|
* FreeBSD4: opt_{inet,inet6,ipsec,ip6fw,altq}.h
|
|
* NetBSD: opt_{inet,ipsec,altq}.h
|
|
* others: does not use defopt
|
|
*
|
|
* - IN_MULTICAST/IN_CLASS[A-D] macro.
|
|
* OpenBSD and NetBSD: net endian (kernel) or host endian (userland)
|
|
* others: always host endian
|
|
*
|
|
* - (m->m_flags & M_EXT) != 0 does *not* mean that the max data length of
|
|
* the mbuf == MCLBYTES.
