malloc types into a structure, a pointer to which is passed around,
instead of an int constant. Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.
to mention here. notable changes are like below.
kernel:
- make PF_KEY kernel interface more robust against broken input stream.
it includes complete internal structure change in sys/netkey/key.c.
- remove non-RFC compliant change in PF_KEY API, in particular,
in struct sadb_msg. we cannot just change these standard structs.
sadb_x_sa2 is introduced instead.
- remove prototypes for pfkey_xx functions from /usr/include/net/pfkeyv2.h.
these functions are not supplied in /usr/lib.
setkey(8):
- get/delete does not require "-m mode" (ignored with warning, if you
specify it)
- spddelete takes direction specification
- interop issues in ipcomp is fixed
- padding type (after ESP) is configurable
- key database memory management (need more fixes)
- policy specification is revisited
XXX m->m_pkthdr.rcvif is still overloaded - hope to fix it soon
