Repair test coverage.  I revert by proxy as the committer seems too busy to even reply mail.

Provide some way for small machines to run subset test so that they get
shorter run time at the expense of test coverage.

The ATF design is O(N^2) in the number of TCs in one TP, which on some
slower platforms causes the net/ipsec tests to take as much as 30% of
the total time to run all of the ATF tests.  Reduce the number of TCs
in various net/ipsec TPs by iterating over *_ALGORITHMS_MINIMUM rather
than *_ALGORITHMS.  Various of the net/ipsec tests already use the
smaller lists, so change the rest of them to do so as well.

Enable DEBUG for babylon5
Apply C99-style struct initialization to xformsw
Tweak outputs of netstat -s for IPsec

- Get rid of "Fast"
- Use ipsec and ipsec6 for titles to clarify protocol
- Indent outputs of sub protocols

Original outputs were organized like this:

(Fast) IPsec:
IPsec ah:
IPsec esp:
IPsec ipip:
IPsec ipcomp:
(Fast) IPsec:
IPsec ah:
IPsec esp:
IPsec ipip:
IPsec ipcomp:

New outputs are organized like this:

Add test cases for IPComp
Simplify IPSEC_OSTAT macro (NFC)
KNF; replace leading whitespaces with hard tabs
Introduce and use SADB_SASTATE_USABLE_P
Add update command for testing

Updating an SA (SADB_UPDATE) requires that a process issuing
SADB_UPDATE is the same as a process issued SADB_ADD (or SADB_GETSPI).
This means that update command must be used with add command in a
configuration of setkey. This usage is normally meaningless but
useful for testing (and debugging) purposes.
Add test cases for updating SA/SP

The tests require newly-added udpate command of setkey.
PR/52346: Frank Kardel: Fix checksumming for NAT-T
See XXX for improvements.

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.
Fix usages of sadb_msg_errno
Avoid updating sav directly

On SADB_UPDATE a target sav was updated directly, which was unsafe.
Instead allocate another sav, copy variables of the old sav to
the new one and replace the old one with the new one.
Simplify; we can assume sav->tdb_xform cannot be NULL while it's valid
Rename key_alloc* functions (NFC)

We shouldn't use the term "alloc" for functions that just look up
data and actually don't allocate memory.
Use explicit_memset to surely zero-clear key_auth and key_enc
Make sure to clear keys on error paths of key_setsaval
Add missing KEY_FREESAV
Make sure a sav is inserted to a sah list after its initialization completes
Remove unnecessary zero-clearing codes from key_setsaval

key_setsaval is now used only for a newly-allocated sav. (It was
used to reset variables of an existing sav.)
Correct wrong assumption of sav->refcnt in key_delsah

A sav in a list is basically not to be sav->refcnt == 0. And also
KEY_FREESAV assumes sav->refcnt > 0.
Let key_getsavbyspi take a reference of a returning sav
Use time_mono_to_wall (NFC)
Separate sending message routine (NFC)
Simplify; remove unnecessary zero-clears

key_freesaval is used only when a target sav is being destroyed.
Omit NULL checks for sav->lft_c

sav->lft_c can be NULL only when initializing or destroying sav.
Omit unnecessary NULL checks for sav->sah
Omit unnecessary check of sav->state

key_allocsa_policy picks a sav of either MATURE or DYING so we
don't need to check its state again.
Simplify; omit unnecessary saidx passing

- ipsec_nextisr returns a saidx but no caller uses it
- key_checkrequest is passed a saidx but it can be gotton by
  another argument (isr)
Fix splx isn't called on some error paths
Fix header size calculation of esp where sav is NULL
Fix header size calculation of ah in the case sav is NULL

This fix was also needed for esp.
Pass sav directly to opencrypto callback

In a callback, use a passed sav as-is by default and look up a sav
only if the passed sav is dead.
Avoid examining freshness of sav on packet processing

If a sav list is sorted (by lft_c->sadb_lifetime_addtime) in advance,
we don't need to examine each sav and also don't need to delete one
on the fly and send up a message. Fortunately every sav lists are sorted
as we need.

Added key_validate_savlist validates that each sav list is surely sorted
(run only if DEBUG because it's not cheap).
Add test cases for SAs with different SPIs
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.
Fix wrong argument handling
fix printf format.
Don't validate sav lists of LARVAL or DEAD states

We don't sort the lists so the validation will always fail.

Fix PR kern/52405
Make sure to sort the list when changing the state by key_sa_chgstate
Rename key_allocsa_policy to key_lookup_sa_bysaidx
Separate test files
Calculate ah_max_authsize on initialization as well as esp_max_ivlen
Remove m_tag_find(PACKET_TAG_IPSEC_PENDING_TDB) because nobody sets the tag
Restore a comment removed in previous

The comment is valid for the below code.
Make tests more stable

sleep command seems to wait longer than expected on anita so
use polling to wait for a state change.
Add tests that explicitly delete SAs instead of waiting for expirations
Remove invalid M_AUTHIPDGM check on ESP isr->sav

M_AUTHIPDGM flag is set to a mbuf in ah_input_cb. An sav of ESP can
have AH authentication as sav->tdb_authalgxform. However, in that
case esp_input and esp_input_cb are used to do ESP decryption and
AH authentication and M_AUTHIPDGM never be set to a mbuf. So
checking M_AUTHIPDGM of a mbuf on isr->sav of ESP is meaningless.
Look up sav instead of relying on unstable sp->req->sav

This code is executed only in an error path so an additional lookup
doesn't matter.
Correct a comment
Don't release sav if calling crypto_dispatch again
Remove extra KEY_FREESAV from ipsec_process_done

It should be done by the caller.
Don't bother the case of crp->crp_buf == NULL in callbacks
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.
Don't make SAs expired on tests that delete SAs explicitly
Fix a debug message
Dedup error paths (NFC)
Use pool to allocate tdb_crypto

For ESP and AH, we need to allocate an extra variable space in addition
to struct tdb_crypto. The fixed size of pool items may be larger than
an actual requisite size of a buffer, but still the performance
improvement by replacing malloc with pool wins.
Don't use unstable isr->sav for header size calculations

We may need to optimize to not look up sav here for users that
don't need to know an exact size of headers (e.g., TCP segmemt size
Don't use sp->req->sav when handling NAT-T ESP fragmentation

In order to do this we need to look up a sav however an additional
look-up degrades performance. A sav is later looked up in
ipsec4_process_packet so delay the fragmentation check until then
to avoid an extra look-up.
Don't use key_lookup_sp that depends on unstable sp->req->sav

It provided a fast look-up of SP. We will provide an alternative
method in the future (after basic MP-ification finishes).
Stop setting isr->sav on looking up sav in key_checkrequest
Remove ipsecrequest#sav
Stop setting mtag of PACKET_TAG_IPSEC_IN_DONE because there is no users anymore
Skip ipsec_spi_*_*_preferred_new_timeout when running on qemu

Probably due to PR 43997
Add localcount to rump kernels
Remove unused macro
Fix key_getcomb_setlifetime

The fix adjusts a soft limit to be 80% of a corresponding hard limit.

I'm not sure the fix is really correct though, at least the original
code is wrong. A passed comb is zero-cleared before calling
key_getcomb_setlifetime, so
  comb->sadb_comb_soft_addtime = comb->sadb_comb_soft_addtime * 80 / 100;
is meaningless.
Provide and apply key_sp_refcnt (NFC)

It simplifies further changes.
Fix indentation

Pointed out by knakahara@
Use pslist(9) for sptree
Don't acquire global locks for IPsec if NET_MPSAFE

Note that the change is just to make testing easy and IPsec isn't MP-safe yet.
Let PF_KEY socks hold their own lock instead of softnet_lock

Operations on SAD and SPD are executed via PF_KEY socks. The operations
include deletions of SAs and SPs that will use synchronization mechanisms
such as pserialize_perform to wait for references to SAs and SPs to be
released. It is known that using such mechanisms with holding softnet_lock
causes a dead lock. We should avoid the situation.
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.

Proposed on tech-kern@ and tech-net@
Fix updating ipsec_used

- key_update_used wasn't called in key_api_spddelete2 and key_api_spdflush
- key_update_used wasn't called if an SP had been added/deleted but
  a reply to userland failed
Fix updating ipsec_used; turn on when SPs on sockets are added
Add missing IPsec policy checks to icmp6_rip6_input

icmp6_rip6_input is quite similar to rip6_input and the same checks exist
in rip6_input.
Add test cases for setsockopt(IP_IPSEC_POLICY)
Don't use KEY_NEWSP for dummy SP entries

By the change KEY_NEWSP is now not called from softint anymore
and we can use kmem_zalloc with KM_SLEEP for KEY_NEWSP.
Comment out unused functions
Add test cases that there are SPs but no relevant SAs
Don't allow sav->lft_c to be NULL

lft_c of an sav that was created by SADB_GETSPI could be NULL.
Clean up clunky eval strings

- Remove unnecessary \ at EOL
  - This allows to omit ; too
- Remove unnecessary quotes for arguments of atf_set
- Don't expand $DEBUG in eval
  - We expect it's expanded on execution

Suggested by kre@
Remove unnecessary KEY_FREESAV in an error path

sav should be freed (unreferenced) by the caller.
Use pslist(9) for sahtree
Use pslist(9) for sah->savtree
Rename local variable newsah to sah

It may not be new.
MP-ify SAD slightly

- Introduce key_sa_mtx and use it for some list operations
- Use pserialize for some list iterations
Introduce KEY_SA_UNREF and replace KEY_FREESAV with it where sav will never be actually freed in the future

KEY_SA_UNREF is still key_freesav so no functional change for now.

This change reduces diff of further changes.
Remove out-of-date log output

Pointed out by riastradh@
Use KDASSERT instead of KASSERT for mutex_ownable

Because mutex_ownable is too heavy to run in a fast path

Suggested by riastradh@
Assemble global lists and related locks into cache lines (NFCI)

Also rename variable names from *tree to *list because they are
just lists, not trees.

Add missing mutex_exit
Fix setkey -D -P outputs

The outputs were tweaked (by me), but I forgot updating libipsec
in my local ATF environment...
MP-ify SAD (key_sad.sahlist and sah entries)

localcount(9) is used to protect key_sad.sahlist and sah entries
as well as SPD (and will be used for SAD sav).

Please read the locking notes of SAD for more details.
Introduce key_sa_refcnt and replace sav->refcnt with it (NFC)
Destroy sav only in the loop for DEAD sav
Fix KASSERT(solocked(sb->sb_so)) failure in sbappendaddr that is called eventually from key_sendup_mbuf

If key_sendup_mbuf isn't passed a socket, the assertion fails.
Originally in this case sb->sb_so was softnet_lock and callers
held softnet_lock so the assertion was magically satisfied.
Now sb->sb_so is key_so_mtx and also softnet_lock isn't always
held by callers so the assertion can fail.

Fix it by holding key_so_mtx if key_sendup_mbuf isn't passed a socket.

Reported by knakahara@
Tested by knakahara@ and ozaki-r@
Fix locking notes of SAD
Fix deadlock between key_sendup_mbuf called from key_acquire and localcount_drain

If we call key_sendup_mbuf from key_acquire that is called on packet
processing, a deadlock can happen like this:
- At key_acquire, a reference to an SP (and an SA) is held
- key_sendup_mbuf will try to take key_so_mtx
- Some other thread may try to localcount_drain to the SP with
  holding key_so_mtx in say key_api_spdflush
- In this case localcount_drain never return because key_sendup_mbuf
  that has stuck on key_so_mtx never release a reference to the SP

Fix the deadlock by deferring key_sendup_mbuf to the timer
Fix that prev isn't cleared on retry
Limit the number of mbufs queued for deferred key_sendup_mbuf

It's easy to be queued hundreds of mbufs on the list under heavy
network load.
MP-ify SAD (savlist)

localcount(9) is used to protect savlist of sah. The basic design is
similar to MP-ifications of SPD and SAD sahlist. Please read the
locking notes of SAD for more details.
Simplify ipsec_reinject_ipstack (NFC)
Add per-CPU rtcache to ipsec_reinject_ipstack

It reduces route lookups and also reduces rtcache lock contentions
when NET_MPSAFE is enabled.
Use pool_cache(9) instead of pool(9) for tdb_crypto objects

The change improves network throughput especially on multi-core systems.

ipsec(4), opencrypto(9) and vlan(4) are now MP-safe.
Write known issues on scalability
Share a global dummy SP between PCBs

It's never be changed so it can be pre-allocated and shared safely between PCBs.
Fix race condition on the rawcb list shared by rtsock and keysock

keysock now protects itself by its own mutex, which means that
the rawcb list is protected by two different mutexes (keysock's one
and softnet_lock for rtsock), of course it's useless.

Fix the situation by having a discrete rawcb list for each.
Use a dedicated mutex for rt_rawcb instead of softnet_lock if NET_MPSAFE
fix localcount leak in sav. fixed by ozaki-r@n.o.

I commit on behalf of him.
remove unnecessary comment.
Fix deadlock between pserialize_perform and localcount_drain

A typical ussage of localcount_drain looks like this:

  item = remove_from_list();
  localcount_drain(&item->localcount, &cv, &mtx);

This sequence can cause a deadlock which happens for example on the following

- Thread A calls localcount_drain which calls xc_broadcast after releasing
  a specified mutex
- Thread B enters the sequence and calls pserialize_perform with holding
  the mutex while pserialize_perform also calls xc_broadcast
- Thread C (xc_thread) that calls an xcall callback of localcount_drain tries
  to hold the mutex

xc_broadcast of thread B doesn't start until xc_broadcast of thread A
finishes, which is a feature of xcall(9). This means that pserialize_perform
never complete until xc_broadcast of thread A finishes. On the other hand,
thread C that is a callee of xc_broadcast of thread A sticks on the mutex.
Finally the threads block each other (A blocks B, B blocks C and C blocks A).

A possible fix is to serialize executions of the above sequence by another
mutex, but adding another mutex makes the code complex, so fix the deadlock
by another way; the fix is to release the mutex before pserialize_perform
and instead use a condvar to prevent pserialize_perform from being called

Note that the deadlock has happened only if NET_MPSAFE is enabled.
Add missing ifdef NET_MPSAFE
Take softnet_lock on pr_input properly if NET_MPSAFE

Currently softnet_lock is taken unnecessarily in some cases, e.g.,
icmp_input and encap4_input from ip_input, or not taken even if needed,
e.g., udp_input and tcp_input from ipsec4_common_input_cb. Fix them.

NFC if NET_MPSAFE is disabled (default).
