PR/56836: Andrew Cagney: IPv6 ESN tunneling IPcomp has corrupt header

Always always send / expect CPI in IPcomp header

Fixes kern/56836 where an IPsec interop combining compression and
ESP|AH would fail.

Since fast ipsec, the outgoing IPcomp header has contained the
compression algorithm instead of the CPI.  Adding the
SADB_X_EXT_RAWCPI flag worked around this but ...

The IPcomp's SADB was unconditionally hashed using the compression
algorithm instead of the CPI.  This meant that an incoming packet with
a valid CPI could never match its SADB.

opencrypto: Rip out EAGAIN logic when unregistering crypto drivers.

I'm pretty sure this never worked reliably based on code inspection,
and it's unlikely to have ever been tested because it only applies
when unregistering a driver -- but we have no crypto drivers for
removable devices, so it would only apply if we went out of our way
to trigger detach with drvctl.

Instead, just make the operation fail with ENODEV, and remove all the
callback logic to resubmit the request on EAGAIN.  (Maybe this should
be ENXIO, but crypto_kdispatch already does ENODEV.)

Make IPsec SPD MP-safe

We use localcount(9), not psref(9), to make the sptree and secpolicy (SP)
entries MP-safe because SPs need to be referenced over opencrypto
processing that executes a callback in a different context.

SPs on sockets aren't managed by the sptree and can be destroyed in softint.
localcount_drain cannot be used in softint so we delay the destruction of
such SPs to a thread context. To do so, a list to manage such SPs is added
(key_socksplist) and key_timehandler_spd deletes dead SPs in the list.

For more details please read the locking notes in key.c.

Use pool to allocate tdb_crypto

For ESP and AH, we need to allocate an extra variable space in addition

an actual requisite size of a buffer, but still the performance
improvement by replacing malloc with pool wins.

Hold a reference to an SP during opencrypto processing

An SP has a list of isr (ipsecrequest) that represents a sequence
of IPsec encryption/authentication processing. One isr corresponds
to one opencrypto processing. The lifetime of an isr follows its SP.

We pass an isr to a callback function of opencrypto to continue
to a next encryption/authentication processing. However nobody
guaranteed that the isr wasn't freed, i.e., its SP wasn't destroyed.

In order to avoid such unexpected destruction of isr, hold a reference
to its SP during opencrypto processing.

Prepare to stop using isr->sav

isr is a shared resource and using isr->sav as a temporal storage
for each packet processing is racy. And also having a reference from
isr to sav makes the lifetime of sav non-deterministic; such a reference
is removed when a packet is processed and isr->sav is overwritten by
new one. Let's have a sav locally for each packet processing instead of
using shared isr->sav.

However this change doesn't stop using isr->sav yet because there are
some users of isr->sav. isr->sav will be removed after the users find
a way to not use isr->sav.

Remove codes for PACKET_TAG_IPSEC_IN_CRYPTO_DONE

It seems that PACKET_TAG_IPSEC_IN_CRYPTO_DONE is for network adapters
that have IPsec accelerators; a driver sets the mtag to a packet
when its device has already encrypted the packet.

Unfortunately no driver implements such offload features for long
years and seems unlikely to implement them soon. (Note that neither
FreeBSD nor Linux doesn't have such drivers.) Let's remove related
(unused) codes and simplify the IPsec code.

PR/47886: Dr. Wolfgang Stukenbrock: IPSEC_NAT_T enabled kernels may access
outdated pointers and pass ESP data to UPD-sockets.
While here, simplify the code and remove the IPSEC_NAT_T option; always
compile nat-traversal in so that it does not bitrot.

Make sure the mbufs in the input path (only the parts which we are going
to modify in the AH case) are writable/non-shared.
This addresses PR kern/33162 by Jeff Rizzo, and replaces the insufficient
patch from that time by a radical solution.
(The PR's problem had been worked around by rev.1.3 of xennetback_xenbus.c,
so it needs a network driver modification to reproduce it.)
Being here, clarify a bit of ipcomp -- uncompression is done in-place,
the header must be removed explicitly.

As a first step towards more fine-grained locking, don't require
crypto_{new.free}session() to be called with the "crypto_mtx"
spinlock held.
This doesn't change much for now because these functions acquire
the said mutex first on entry now, but at least it keeps the nasty
locks local to the opencrypto core.

small modifications in dealing with the unknown result size of compression/
decompression:
-seperate the IPCOMP specific rule that compression must not grow the
 data from general compression semantics: Introduce a special name
 CRYPTO_DEFLATE_COMP_NOGROW/comp_algo_deflate_nogrow to describe
 the IPCOMP semantics and use it there. (being here, fix the check
 so that equal size is considered failure as well as required by
 RFC2393)
 Customers of CRYPTO_DEFLATE_COMP/comp_algo_deflate now always get
 deflated data back, even if they are not smaller than the original.
-allow to pass a "size hint" to the DEFLATE decompression function
 which is used for the initial buffer allocation. Due to the changes
 done there, additional allocations and extra copies are avoided if the
 initial allocation is sufficient. Set the size hint to MCLBYTES (=2k)
 in IPCOMP which should be good for many use cases.

Rework opencrypto to use a spin mutex (crypto_mtx) instead of "splcrypto"
(actually splnet) and condvars instead of tsleep/wakeup.  Fix a few
miscellaneous problems and add some debugging printfs while there.

Restore set of CRYPTO_F_DONE in crypto_done() which was lost at some
point after this code came from FreeBSD -- it made it impossible to wait
properly for a condition.

Add flags analogous to the "crp" flags to the key operation's krp struct.
Add a new flag, CRYPTO_F_ONRETQ which tells us a request finished before
the kthread had a chance to dequeue it and call its callback -- this was
letting requests stick on the queues before even though done and copied
out.

Callers of crypto_newsession() or crypto_freesession() must now take the
mutex.  Change netipsec to do so.  Dispatch takes the mutex itself as
needed.

This was tested fairly extensively with the cryptosoft backend and lightly
with a new hardware driver.  It has not been tested with FAST_IPSEC; I am
unable to ascertain whether FAST_IPSEC currently works at all in our tree.

pjd@FreeBSD.ORG, ad@NetBSD.ORG, and darran@snark.us pointed me in the
right direction several times in the course of this.  Remaining bugs
are mine alone.

Reversion of "netkey merge", part 2 (replacement of removed files in the
repository by christos was part 1).  netipsec should now be back as it
was on 2003-09-11, with some very minor changes:

1) Some residual platform-dependent code was moved from ipsec.h to
   ipsec_osdep.h; without this, IPSEC_ASSERT() was multiply defined.  ipsec.h
   now includes ipsec_osdep.h

2) itojun's renaming of netipsec/files.ipsec to netipsec/files.netipsec has
   been left in place (it's arguable which name is less confusing but the
   rename is pretty harmless).

3) Some #endif TOKEN has been replaced by #endif /* TOKEN */; #endif TOKEN
   is invalid and GCC 3 won't compile it.

An i386 kernel with "options FAST_IPSEC" and "options OPENCRYPTO" now
gets through "make depend" but fails to build with errors in ip_input.c.
But it's better than it was (thank heaven for small favors).

Initial import of Sam Leffler's `Fast-IPsec' from FreeBSD 4.
Fast-IPsec is a rework of the OpenBSD and KAME IPsec code, using the
OpenCryptoFramework (and thus hardware crypto accelerators) and
numerous detailed performance improvements.

This import is (aside from SPL-level names) the FreeBSD source,
imported ``as-is'' as a historical snapshot, for future maintenance
and comparison against the FreeBSD source.  For now, several minor
kernel-API differences are hidden by macros a shim file, ipsec_osdep.h,
which (aside from SPL names) can be targeted at either NetBSD or FreeBSD.
