ozaki-r | inpcb: separate inpcb again to reduce the size of PCB for IPv4
The data size of PCB for IPv4 increased because of the merge of
struct in6pcb. The change decreases the size to the original size by
separating struct inpcb (again). struct in4pcb and in6pcb that embed
struct inpcb are introduced.
Even after the separation, users don't need to realize the separation
and only have to use some macros to access dedicated data. For example,
inp->inp_laddr is now accessed through in4p_laddr(inp).

ozaki-r | inpcb: integrate data structures of PCB into one
Data structures of network protocol control blocks (PCBs), i.e.,
struct inpcb, in6pcb and inpcb_hdr, are not organized well. Users of
the data structures have to handle them separately and thus the code
is cluttered and duplicated.
The commit integrates the data structures into one, struct inpcb. As a
result, users of PCBs only have to handle just one data structure, so
the code becomes simple.
One drawback is that the data size of PCB for IPv4 increases by 40 bytes
(from 248 bytes to 288 bytes).

christos | - Make ALIGNED_POINTER use __alignof(t) instead of sizeof(t). This is more
correct because it works with non-primitive types and provides the ABI
alignment for the type the compiler will use.
- Remove all the *_HDR_ALIGNMENT macros and asserts
- Replace POINTER_ALIGNED_P with ACCESSIBLE_POINTER which is identical to
ALIGNED_POINTER, but returns that the pointer is always aligned if the
CPU supports unaligned accesses.

Setsockopt will now reject UDP_ENCAP_ESPINUDP_NON_IKE.

maxv | If the socket wants a ESP-over-UDP packet, and the packet is incorrect,
stop processing it instead of giving it to udp4_sendup. It just doesn't
make any sense not to drop it.
I was already telling myself this the other day when I visited this place,
but I just saw PR/36782 (11 years old) that suggests the exact same thing,
so fix it.
Now, udp4_espinudp always frees the mbuf, and is made void. The packet is
not processed any further afterwards.

Here the next mbufs in the chain are not freed. Seems easy to remotely
DoS the system by sending fragmented keepalives in a loop.
* If !ipsec_used, free the mbuf.
* In udp_input, we need to update 'uh', because udp4_realinput may have
modified the chain. Perhaps we also need to re-enforce alignment, so
add an XXX.

knakahara | branches: 1.229.2;
fix: "ifconfig destory" can stalls when "ifconfig" is done parallel.
This problem occurs only if NET_MPSAFE on.
ifconfig destroy side:
kernel entry point is ifioctl => if_clone_destroy.
pr_purgeif() acquires softnet_lock, and then ifa_remove() calls
pserialize_perform() holding softnet_lock.
ifconfig side:
kernel entry point is socreate.
pr_attach()(udp_attach_wrapper()) calls sosetlock(). In this call path,
sosetlock() try to acquire softnet_lock.
These can cause dead lock.

ozaki-r | branches: 1.226.2;
Avoid storing a pointer of an interface in a mbuf
Having a pointer of an interface in a mbuf isn't safe if we remove big
kernel locks; an interface object (ifnet) can be destroyed anytime in any
packet processing and accessing such object via a pointer is racy. Instead
we have to get an object from the interface collection (ifindex2ifnet) via
an interface index (if_index) that is stored to a mbuf instead of an
pointer.
The change provides two APIs: m_{get,put}_rcvif_psref that use psref(9)
for sleep-able critical sections and m_{get,put}_rcvif that use
pserialize(9) for other critical sections. The change also adds another
API called m_get_rcvif_NOMPSAFE, that is NOT MP-safe and for transition
moratorium, i.e., it is intended to be used for places where are not
planned to be MP-ified soon.
The change adds some overhead due to psref to performance sensitive paths,
however the overhead is not serious, 2% down at worst.
Proposed on tech-kern and tech-net.

Patch posted to tech-net@
http://mail-index.netbsd.org/tech-net/2015/03/15/msg005004.html
The choice to use a new structure sockaddr_big has been retained since
changing sockaddr_storage size would lead to unnecessary ABI change. The
use of the new structure does not preclude future work that increases
the size of sockaddr_storage and at that time sockaddr_big may be
trivially replaced.

dyoung | Reduces the resources demanded by TCP sessions in TIME_WAIT-state using
methods called Vestigial Time-Wait (VTW) and Maximum Segment Lifetime
Truncation (MSLT).
MSLT and VTW were contributed by Coyote Point Systems, Inc.
Even after a TCP session enters the TIME_WAIT state, its corresponding
socket and protocol control blocks (PCBs) stick around until the TCP
Maximum Segment Lifetime (MSL) expires. On a host whose workload
necessarily creates and closes down many TCP sockets, the sockets & PCBs
for TCP sessions in TIME_WAIT state amount to many megabytes of dead
weight in RAM.
Maximum Segment Lifetimes Truncation (MSLT) assigns each TCP session to
a class based on the nearness of the peer. Corresponding to each class
is an MSL, and a session uses the MSL of its class. The classes are
loopback (local host equals remote host), local (local host and remote
host are on the same link/subnet), and remote (local host and remote
host communicate via one or more gateways). Classes corresponding to
nearer peers have lower MSLs by default: 2 seconds for loopback, 10
seconds for local, 60 seconds for remote. Loopback and local sessions
expire more quickly when MSLT is used.
Vestigial Time-Wait (VTW) replaces a TIME_WAIT session's PCB/socket
dead weight with a compact representation of the session, called a
"vestigial PCB". VTW data structures are designed to be very fast and
memory-efficient: for fast insertion and lookup of vestigial PCBs,
the PCBs are stored in a hash table that is designed to minimize the
number of cacheline visits per lookup/insertion. The memory both
for vestigial PCBs and for elements of the PCB hashtable come from
fixed-size pools, and linked data structures exploit this to conserve
memory by representing references with a narrow index/offset from the
start of a pool instead of a pointer. When space for new vestigial PCBs
runs out, VTW makes room by discarding old vestigial PCBs, oldest first.
VTW cooperates with MSLT.
It may help to think of VTW as a "FIN cache" by analogy to the SYN
cache.
A 2.8-GHz Pentium 4 running a test workload that creates TIME_WAIT
sessions as fast as it can is approximately 17% idle when VTW is active
versus 0% idle when VTW is inactive. It has 103 megabytes more free RAM
when VTW is active (approximately 64k vestigial PCBs are created) than
when it is inactive.

Cosmetic: change types of variables to avoid oodles of casts: in
in6_src.c, avoid casts by changing several route_in6 pointers
to struct route pointers. Remove unnecessary casts to caddr_t
elsewhere.
Pave the way for eliminating address family-specific route caches:
soon, struct route will not embed a sockaddr, but it will hold
a reference to an external sockaddr, instead. We will set the
destination sockaddr using rtcache_setdst(). (I created a stub
for it, but it isn't used anywhere, yet.) rtcache_free() will
free the sockaddr. I have extracted from rtcache_free() a helper
subroutine, rtcache_clear(). rtcache_clear() will "forget" a
cached route, but it will not forget the destination by releasing
the sockaddr. I use rtcache_clear() instead of rtcache_free()
in rtcache_update(), because rtcache_update() is not supposed
to forget the destination.
Constify:
1 Introduce const accessor for route->ro_dst, rtcache_getdst().
2 Constify the 'dst' argument to ifnet->if_output(). This
led me to constify a lot of code called by output routines.
3 Constify the sockaddr argument to protosw->pr_ctlinput. This
led me to constify a lot of code called by ctlinput routines.
4 Introduce const macros for converting from a generic sockaddr
to family-specific sockaddrs, e.g., sockaddr_in: satocsin6,
satocsin, et cetera.

tls | Protect calls to pool_put/pool_get that may occur in interrupt context
with spl used to protect other allocations and frees, or datastructure
element insertion and removal, in adjacent code.
It is almost unquestionably the case that some of the spl()/splx() calls
added here are superfluous, but it really seems wrong to see:
s=splfoo();
/* frob data structure */
splx(s);
pool_put(x);
and if we think we need to protect the first operation, then it is hard
to see why we should not think we need to protect the next. "Better
safe than sorry".
It is also almost unquestionably the case that I missed some pool
gets/puts from interrupt context with my strategy for finding these
calls; use of PR_NOWAIT is a strong hint that a pool may be used from
interrupt context but many callers in the kernel pass a "can wait/can't
wait" flag down such that my searches might not have found them. One
notable area that needs to be looked at is pf.

Better support of IPv6 scoped addresses.
- most of the kernel code will not care about the actual encoding of
scope zone IDs and won't touch "s6_addr16[1]" directly.
- similarly, most of the kernel code will not care about link-local
scoped addresses as a special case.
- scope boundary check will be stricter. For example, the current
*BSD code allows a packet with src=::1 and dst=(some global IPv6
address) to be sent outside of the node, if the application do:
s = socket(AF_INET6);
bind(s, "::1");
sendto(s, some_global_IPv6_addr);
This is clearly wrong, since ::1 is only meaningful within a single
node, but the current implementation of the *BSD kernel cannot
reject this attempt.
- and, while there, don't try to remove the ff02::/32 interface route
entry in in6_ifdetach() as it's already gone.
This also includes some level of support for the standard source
address selection algorithm defined in RFC3484, which will be
completed on in the future.

Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(),
vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all
nodes are registered with the tree, and nodes can be added (or
removed) easily, and I/O to and from the tree is handled generically.
Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded. Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.
All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.
PS - I'm sorry, but there's a distinct lack of documentation at the
moment. I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.

when an address is deleted from an interface, notify/abort all sockets
that have that address as a source. Switch IGMP and multicasts to use pools
for allocation. Fix a number of potential problems in the igmp code where
allocation failures could cause a trap/panic.

thorpej | Changes to allow the IPv4 and IPv6 layers to align headers themseves,
as necessary:
* Implement a new mbuf utility routine, m_copyup(), is is like
m_pullup(), except that it always prepends and copies, rather
than only doing so if the desired length is larger than m->m_len.
m_copyup() also allows an offset into the destination mbuf, which
allows space for packet headers, in the forwarding case.
* Add *_HDR_ALIGNED_P() macros for IP, IPv6, ICMP, and IGMP. These
macros expand to 1 if __NO_STRICT_ALIGNMENT is defined, so that
architectures which do not have strict alignment constraints don't
pay for the test or visit the new align-if-needed path.
* Use the new macros to check if a header needs to be aligned, or to
assert that it already is, as appropriate.
Note: This code is still somewhat experimental. However, the new
code path won't be visited if individual device drivers continue
to guarantee that packets are delivered to layer 3 already properly
aligned (which are rules that are already in use).

thorpej | Implement support for IP/TCP/UDP checksum offloading provided by
network interfaces. This works by pre-computing the pseudo-header
checksum and caching it, delaying the actual checksum to ip_output()
if the hardware cannot perform the sum for us. In-bound checksums
can either be fully-checked by hardware, or summed up for final
verification by software. This method was modeled after how this
is done in FreeBSD, although the code is significantly different in
most places.
We don't delay checksums for IPv6/TCP, but we do take advantage of the
cached pseudo-header checksum.
Note: hardware-assisted checksumming defaults to "off". It is
enabled with ifconfig(8). See the manual page for details.
Implement hardware-assisted checksumming on the DP83820 Gigabit Ethernet,
3c90xB/3c90xC 10/100 Ethernet, and Alteon Tigon/Tigon2 Gigabit Ethernet.

itojun | introduce m->m_pkthdr.aux to hold random data which needs to be passed

ipsec socket pointers, ipsec decryption/auth information, tunnel
decapsulation information are in my mind - there can be several other usage.
at this moment, we use this for ipsec socket pointer passing. this will
avoid reuse of m->m_pkthdr.rcvif in ipsec code.
due to the change, MHLEN will be decreased by sizeof(void *) - for example,
for i386, MHLEN was 100 bytes, but is now 96 bytes.
we may want to increase MSIZE from 128 to 256 for some of our architectures.
take caution if you use it for keeping some data item for long period
of time - use extra caution on M_PREPEND() or m_adj(), as they may result
in loss of m->m_pkthdr.aux pointer (and mbuf leak).
this will bump kernel version.

thorpej | First-draft if_detach() implementation, originally from Bill Studnemund,
although this version has been changed somewhat:
- reference counting on ifaddrs isn't as complete as Bill's original
work was. This is hard to get right, and we should attack one
protocol at a time.
- This doesn't do reference counting or dynamic allocation of ifnets yet.
- This version introduces a new PRU -- PRU_PURGEADDR, which is used to
purge an ifaddr from a protocol. The old method Bill used didn't work
on all protocols, and it only worked on some because it was Very Lucky.
This mostly works ... i.e. works for my USB Ethernet, except for a dangling
ifaddr reference left by the IPv6 code; have not yet tracked this down.

darrenr | Apply the aborted ktrace-lwp changes to a specific branch. This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it. This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.

Fix a bug in ESP over UDP: because udp4_espinudp() called m_pullup, it
could modify the struct mbuf and calling functions (udp_input() and
udp4_realinput()) would have used a garbled local copy of the pointer.
The fix is not perfect. udp4_espinudp() should use m_pulldown()...

- Adjust socreate(9) and sonewconn(9) to call pr_attach without the
socket lock held (as a preparation for the locking scheme adjustment).
- Adjust all pr_attach routines to assert that PCB is not set.
- Sprinkle various comments, document some routines and their locking.

rmind | Checkpoint work in progress:
- Move PCB structures under __INPCB_PRIVATE, adjust most of the callers
and thus make IPv4 PCB structures mostly opaque. Any volunteers for
merging in6pcb with inpcb (see rpaulo-netinet-merge-pcb branch)?
- Move various global vars to the modules where they belong, make them static.
- Some preliminary work for IPv4 PCB locking scheme.
- Make raw IP code mostly MP-safe. Simplify some of it.
- Rework "fast" IP forwarding (ipflow) code to be mostly MP-safe. It should
run from a software interrupt, rather than hard.
- Rework tun(4) pseudo interface to be MP-safe.
- Work towards making some other interfaces more strict.

sys/netinet/udp_usrreq.c: revision 1.237 (via patch)
Fix three pretty bad mistakes in NAT-T:
* If we got a keepalive packet, we need to call m_freem, not m_free.
Here the next mbufs in the chain are not freed. Seems easy to remotely
DoS the system by sending fragmented keepalives in a loop.
* If !ipsec_used, free the mbuf.
* In udp_input, we need to update 'uh', because udp4_realinput may have
modified the chain. Perhaps we also need to re-enforce alignment, so
add an XXX.

socket: report receive buffer overflows
Add soroverflow() which increments the overflow counter, sets so_error
to ENOBUFS and wakes the receive socket up.
Replace all code that manually increments this counter with soroverflow().
Add soroverflow() to raw_input().
This allows userland to detect route(4) overflows so it can re-sync
with the current state.
socket: clear error even when peeking
The error has already been reported and it's pointless requiring another
recv(2) call just to clear it.
socket: remove now incorrect comment that so_error is only udp
As it can be affected by route(4) sockets which are raw.
rtsock: log dropped messages that we cannot report to userland
Handle ENOBUFS when receiving messages.
Don't send messages if the receiver has died.
Sprinkle more soroverflow().
Handle ENOBUFS in recv
Handle ENOBUFS in sendto
Note value received. Harden another sendto for ENOBUFS.
Handle the routing socket overflowing gracefully.
Allow a valid sendto .... duh
Handle errors better.
Fix test for checking we sent all the data we asked to.

Add support IP_PKTINFO for sendmsg(2).
The source address or output interface can be specified by adding IP_PKTINFO
to the control part of the message on a SOCK_DGRAM or SOCK_RAW socket.
Reviewed by ozaki-r@ and christos@. thanks.
--
As is the case with IPV6_PKTINFO, IP_PKTINFO can be sent without EADDRINUSE
even if the UDP address:port in use is specified.
