sctp: sctp_close: fix release of bindings for deferred call_rcu's
It seems due to RCU usage, i.e. within SCTP's address binding list,
a, say, ``behavioral change'' was introduced which does actually
not conform to the RFC anymore. In particular consider the following
(fictional) scenario to demonstrate this:
do:
Two SOCK_SEQPACKET-style sockets are opened (S1, S2)
S1 is bound to 127.0.0.1, port 1024 [server]
S2 is bound to 127.0.0.1, port 1025 [client]
listen(2) is invoked on S1
From S2 we call one sendmsg(2) with msg.msg_name and
msg.msg_namelen parameters set to the server's
address
S1, S2 are closed
goto do
The first pass of this loop passes successful, while the second round
fails during binding of S1 (address still in use). What is happening?
In the first round, the initial handshake is being done, and, at the
time close(2) is called on S1, a non-graceful shutdown is performed via
ABORT since in S1's receive queue an unprocessed packet is present,
thus stating an error condition. This can be considered as a correct
behavior.
During close also all bound addresses are freed, thus nothing *must*
be active anymore. In reference to RFC2960:
After checking the Verification Tag, the receiving endpoint shall
remove the association from its record, and shall report the
termination to its upper layer. (9.1 Abort of an Association)
Also, no half-open states are supported, thus after an ungraceful
shutdown, we leave nothing behind. However, this seems not to be
happening though. In a real-world scenario, this is exactly where
it breaks the lksctp-tools functional test suite, *for instance*:
./test_sockopt
test_sockopt.c 1 PASS : getsockopt(SCTP_STATUS) on a socket with no assoc
test_sockopt.c 2 PASS : getsockopt(SCTP_STATUS)
test_sockopt.c 3 PASS : getsockopt(SCTP_STATUS) with invalid associd
test_sockopt.c 4 PASS : getsockopt(SCTP_STATUS) with NULL associd
test_sockopt.c 5 BROK : bind: Address already in use
The underlying problem is that sctp_endpoint_destroy() hasn't been
triggered yet while the next bind attempt is being done. It will be
triggered eventually (but too late) by sctp_transport_destroy_rcu()
after one RCU grace period:
sctp_transport_destroy()
sctp_transport_destroy_rcu() ----.
sctp_association_put() [*] <--+--> sctp_packet_free()
sctp_association_destroy() [...]
sctp_endpoint_put() skb->destructor
sctp_endpoint_destroy() sctp_wfree()
sctp_bind_addr_free() sctp_association_put() [*]
Thus, we move out the condition with sctp_association_put() as well as
the sctp_packet_free() invocation and the issue can be solved. We also
better free the SCTP chunks first before putting the ref of the association.
With this patch, the example above (which simulates a similar scenario
as in the implementation of this test case) and therefore also the test
suite run successfully through. Tested by myself.

Merge branch 'delete-wanrouter' of git://git./linux/kernel/git/paulg/linux
Paul Gortmaker says:
====================
The removal of wanrouter code was originally listed in the (now
gone) feature removal file since May 2012, and an RFC of the
deletion was posted[1] in late 2012. The overall concept was given
an OK, but defconfig contamination, build failures, etc. meant that
it didn't quite make it into mainline for 3.8.
Since that time, Dan discovered (via code audit) a runtime bug that
proves nobody has been using this for over four years[2]. With that
new information, I think it makes sense for someone to follow through
on Joe's original RFC and get this done for the 3.9 release.
In addition to resolving the build failures of the RFC by keeping
stub headers, this also splits the change into two parts, just like
the token ring removal did. Part #1 decouples the mainline kernel
from the expired subsystem, and part #2 does the large scale
deletion of the subsystem content.
The advantage of the above, is that a "git blame" will never lead
you to a 4000+ line deletion commit. The large scale deletion will
never show up in a "git blame" and hence the same advantages that we
get from the "--irreversible-delete" in the review stage of "git
format-patch" are also embedded into the git history itself. This
may seem like a moot point to some, but for those who spend a
considerable amount of time data mining in the git history, this is
probably worth doing.
I have done build tests of all[mod/yes]config for both the stage 1
(Makefile and Kconfig) and stage 2 (full driver delete) as a sanity
check, and the issues with the previously posted RFC should be gone.
Speaking of "--irreversible-delete" -- these patches were created
with that option, so if you want to use them locally, you are going
to have to pull (location below) the content instead of doing a
"git am" of the mailed out content.

wanrouter: delete now orphaned header content, files/drivers
The wanrouter support was identified earlier as unused for years,
and so the previous commit totally decoupled it from the kernel,
leaving the related wanrouter files present, but totally inert.
Here we take the final step in that cleanup, by doing a wholesale
removal of these files. The two step process is used so that the
large deletion is decoupled from the git history of files that we
still care about.
The drivers deleted here all were dependent on the Kconfig setting
CONFIG_WAN_ROUTER_DRIVERS.
A stub wanrouter.h header (kernel & uapi) are left behind so that
drivers/isdn/i4l/isdn_x25iface.c continues to compile, and so that
we don't accidentally break userspace that expected these defines.

wanrouter: completely decouple obsolete code from kernel.

with the mainline commit
f0d1b3c2bcc5de8a17af5f2274f7fcde8292b5fc
("net/wanrouter: Deprecate and schedule for removal") in May 2012.
More importantly, Dan Carpenter found[1] that the driver had a
fundamental breakage introduced back in 2008, with commit
7be6065b39c3 ("netdevice wanrouter: Convert directly reference of
netdev->priv"). So we know with certainty that the code hasn't been
used by anyone willing to at least take the effort to send an e-mail
report of breakage for at least 4 years.
This commit does a decouple of the wanrouter subsystem, by going
after the Makefile/Kconfig and similar files, so that these mainline
files that we are keeping do not have the big wanrouter file/driver
deletion commit tied into their history.
Once this commit is in place, we then can remove the obsolete cyclomx
drivers and similar that have a dependency on CONFIG_WAN_ROUTER_DRIVERS.

ipv6: add anti-spoofing checks for 6to4 and 6rd
This patch adds anti-spoofing checks in sit.c as specified in RFC3964
section 5.2 for 6to4 and RFC5969 section 12 for 6rd. I left out the
checks which could easily be implemented with netfilter.
Specifically this patch adds following logic (based loosely on the
pseudocode in RFC3964 section 5.2):
if prefix (inner_src_v6) == rd6_prefix (2002::/16 is the default)
and outer_src_v4 != embedded_ipv4 (inner_src_v6)
drop
if prefix (inner_dst_v6) == rd6_prefix (or 2002::/16 is the default)
and outer_dst_v4 != embedded_ipv4 (inner_dst_v6)
drop
accept
To accomplish the specified security checks proposed by above RFCs,
it is still necessary to employ uRPF filters with netfilter. These new
checks only kick in if the employed addresses are within the 2002::/16 or
another range specified by the 6rd-prefix (which defaults to 2002::/16).

ip_gre: When TOS is inherited, use configured TOS value for non-IP packets
A GRE tunnel can be configured so that outgoing tunnel packets inherit
the value of the TOS field from the inner IP header. In doing so, when
a non-IP packet is transmitted through the tunnel, the TOS field will
always be set to 0.
Instead, the user should be able to configure a different TOS value as
the fallback to use for non-IP packets. This is helpful when the non-IP
packets are all control packets and should be handled by routers outside
the tunnel as having Internet Control precedence. One example of this is
the NHRP packets that control a DMVPN-compatible mGRE tunnel; they are
encapsulated directly by GRE and do not contain an inner IP header.
Under the existing behavior, the IFLA_GRE_TOS parameter must be set to
'1' for the TOS value to be inherited. Now, only the least significant
bit of this parameter must be set to '1', and when a non-IP packet is
sent through the tunnel, the upper 6 bits of this same parameter will be
copied into the TOS field. (The ECN bits get masked off as before.)
This behavior is backwards-compatible with existing configurations and
iproute2 versions.
