itojun ec5e739b46 extra blank line 2003-09-23 00:03:05 +00:00
itojun cd71ebe2f7 mark security policy that should persist in the system "persistent". 
this should prevent recently-reported kernel panic when "spdflush" is issued.

itojun c1ae398301 correct hashed SPI lookup. reported by Greg Troxel 2003-09-09 21:58:26 +00:00
itojun 8ca90bd4e4 add /kern/ipsecsa and /kern/ipsecsp, which can be inspected by setkey(8). 
it allows easier access to ipsecsa/sp.  it works around problem where
setkey -D does not work with large number of ipsec SAs due to socket buffer
size.

itojun 800fe5d178 - prepare for RFC2401bis 64bit sequence number (no behavior change yet) 
- use hash for SPI-based SAD entry lookup (should be faster, i hope)
- cleanup keydb.c and key.c.  key.c is responsible for refcounting secasvar,
  keydb.c is responsible for alloc/free.

fvdl d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage, 
and need to be examined and discussed more.

simonb d1c5820781 malloc() returns "void *", we don't need to cast the return value. 2003-06-28 14:33:39 +00:00
darrenr 960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can 
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

thorpej b193480908 Add extensible malloc types, adapted from FreeBSD. This turns 
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.

dan 73aa8b3b5b warn about the arc4 generator if no NRND, but still use it 2002-10-07 00:40:15 +00:00
tls 0f95ec4fd5 ESP output was drawing down the entropy pool at a ferocious rate, a 
particular problem on hosts with only wireless interfaces that are
definitely not safe to use as entropy sources.

Add arc4randbytes() which hands out bytes from the same source used
by arc4random().  This is intended to be a _temporary_ interface
until we can design and implement a better general PRNG interface
that is decoupled from the entropy-pool implementation.

Modify key_randomfill() (used only for initialization vectors on
SA creation and via key_sa_stir_iv(), which does not "stir",
despite its name) to use arc4randbytes() instead of pulling bits
directly from the entropy pool.  It is my hope that this change
will pose minimal integration problems for the KAME folks as the
random-pool interface is *already* different between each BSD
variant; this just simplifies the NetBSD case and solves a
fairly serious problem.

Note that it is generally considered acceptable cryptographic
practice to use a fast stream cipher to generate IVs for encryption
with stronger block ciphers.  For example, the use of "non-Approved"
PRNGs to generate IVs for "Approved" block ciphers is explicitly
sanctioned by FIPS 140-2.
