This patch adds a minimum-length check for ICMPv6 packets, as per the previous
patch for ICMPv4 payloads.

Unlike TCP, which only needs 8 octets of original packet data, DCCP requires
minimally 12 or 16 bytes for ICMP-payload sequence number checks.
This patch replaces the insufficient length constant of 8 with a two-stage
test, making sure that 12 bytes are available, before computing the basic
header length required for sequence number checks.

This adds a sequence number check for ICMPv6 DCCP error packets, in the same

The payload of ICMP message is a part of the packet sent by ourself,
so the sequence number check must use AWL and AWH, not SWL and SWH.
For example:
Endpoint A Endpoint B
DATA-ACK -------->
(SEQ=X)
<-------- ICMP (Fragmentation Needed)
(SEQ=X)

The AWL lower Ack validity window advances in proportion to GSS, the greatest
sequence number sent. Updating AWL other than at connection setup (in the
DCCP-Request sent by dccp_v{4,6}_connect()) was missing in the DCCP code.
This bug lead to syslog messages such as
"kernel: dccp_check_seqno: DCCP: Step 6 failed for DATAACK packet, [...]
P.ackno exists or LAWL(82947089) <= P.ackno(82948208)
<= S.AWH(82948728), sending SYNC..."
The difference between AWL/AWH here is 1639 packets, while the expected value
(the Sequence Window) would have been 100 (the default). A closer look showed
that LAWL = AWL = 82947089 equalled the ISS on the Response.
The patch now updates AWL with each increase of GSS.
Further changes:
----------------
The patch also enforces more stringent checks on the ISS sequence number:
* AWL is initialised to ISS at connection setup and remains at this value;
* AWH is then always set to GSS (via dccp_update_gss());
* so on the first Request: AWL = AWH = ISS,
and on the n-th Request: AWL = ISS, AWH = ISS + n.
As a consequence, only Response packets that refer to Requests sent by this
host will pass, all others are discarded. This is the intention and in effect
implements the initial adjustments for AWL as specified in RFC 4340, 7.5.1.

This patch allows the sender to distinguish original and retransmitted packets,
which is in particular needed for the retransmission of DCCP-Requests:
* the first Request uses ISS (generated in net/dccp/ip*.c), and sets GSS = ISS;
* all retransmitted Requests use GSS' = GSS + 1, so that the n-th retransmitted
Request has sequence number ISS + n (mod 48).
To add generic support, the patch reorganises existing code so that:
* icsk_retransmits == 0 for the original packet and
* icsk_retransmits = n > 0 for the n-th retransmitted packet
at the time dccp_transmit_skb() is called, via dccp_retransmit_skb().
Thanks to Wei Yongjun for pointing this problem out.
Further changes:
----------------
* removed the `skb' argument from dccp_retransmit_skb(), since sk_send_head
is used for all retransmissions (the exception is client-Acks in PARTOPEN
state, but these do not use sk_send_head);
* since sk_send_head always contains the original skb (via dccp_entail()),
skb_cloned() never evaluated to true and thus pskb_copy() was never used.

Removes legacy reinvent-the-wheel type thing. The generic
machinery integrates much better to automated debugging aids
such as kerneloops.org (and others), and is unambiguous due to
better naming. Non-intuively BUG_TRAP() is actually equal to
WARN_ON() rather than BUG_ON() though some might actually be
promoted to BUG_ON() but I left that to future.
I could make at least one BUILD_BUG_ON conversion.

Extend the permission check for networking sysctl's to allow modification
when current process has CAP_NET_ADMIN capability and is not root. This
version uses the until now unused permissions hook to override the mode
value for /proc/sys/net if accessed by a user with capabilities.
Found while working with Quagga. It is impossible to turn forwarding
on/off through the command interface because Quagga uses secure coding
practice of dropping privledges during initialization and only raising via
capabilities when necessary. Since the dameon has reset real/effective
uid after initialization, all attempts to access /proc/sys/net variables
will fail.

All ratelimit user use same jiffies and burst params, so some messages
(callbacks) will be lost.
For example:
a call printk_ratelimit(5 * HZ, 1)
b call printk_ratelimit(5 * HZ, 1) before the 5*HZ timeout of a, then b will
will be supressed.
- rewrite __ratelimit, and use a ratelimit_state as parameter. Thanks for
hints from andrew.
- Add WARN_ON_RATELIMIT, update rcupreempt.h
- remove __printk_ratelimit
- use __ratelimit in net_ratelimit

This patch introduces support for the SOCK_NONBLOCK flag in socket,
socketpair, and paccept. To do this the internal function sock_attach_fd
gets an additional parameter which it uses to set the appropriate flag for
the file descriptor.
Given that in modern, scalable programs almost all socket connections are
non-blocking and the minimal additional cost for the new functionality
I see no reason not to add this code.
The following test must be adjusted for architectures other than x86 and
x86-64 and in case the syscall numbers changed.

Some platforms do not have support to restore the signal mask in the
return path from a syscall. For those platforms syscalls like pselect are
not defined at all. This is, I think, not a good choice for paccept()
since paccept() adds more value on top of accept() than just the signal
mask handling.
Therefore this patch defines a scaled down version of the sys_paccept
function for those platforms. It returns -EINVAL in case the signal mask
is non-NULL but behaves the same otherwise.
Note that I explicitly included <linux/thread_info.h>. I saw that it is
currently included but indirectly two levels down. There is too much risk
in relying on this. The header might change and then suddenly the
function definition would change without anyone immediately noticing.

This patch is by far the most complex in the series. It adds a new syscall
paccept. This syscall differs from accept in that it adds (at the userlevel)
two additional parameters:
- a signal mask
- a flags value
The flags parameter can be used to set flag like SOCK_CLOEXEC. This is
imlpemented here as well. Some people argued that this is a property which
should be inherited from the file desriptor for the server but this is against
POSIX. Additionally, we really want the signal mask parameter as well
(similar to pselect, ppoll, etc). So an interface change in inevitable.
The flag value is the same as for socket and socketpair. I think diverging
here will only create confusion. Similar to the filesystem interfaces where
the use of the O_* constants differs, it is acceptable here.
The signal mask is handled as for pselect etc. The mask is temporarily
installed for the thread and removed before the call returns. I modeled the
code after pselect. If there is a problem it's likely also in pselect.
For architectures which use socketcall I maintained this interface instead of
adding a system call. The symmetry shouldn't be broken.
The following test must be adjusted for architectures other than x86 and
x86-64 and in case the syscall numbers changed.

This patch adds support for flag values which are ORed to the type passwd
to socket and socketpair. The additional code is minimal. The flag
values in this implementation can and must match the O_* flags. This
avoids overhead in the conversion.
The internal functions sock_alloc_fd and sock_map_fd get a new parameters
and all callers are changed.

This is based upon an excellent bug report from Eric Dumazet.
tcp_ack() should clear ->icsk_probes_out even if there are packets
outstanding. Otherwise if we get a sequence of ACKs while we do have
packets outstanding over and over again, we'll never clear the
probes_out value and eventually think the connection is too sick and
we'll reset it.
This appears to be some "optimization" added to tcp_ack() in the 2.4.x
timeframe. In 2.2.x, probes_out is pretty much always cleared by
tcp_ack().
Here is Eric's original report:
----------------------------------------
Apparently, we can in some situations reset TCP connections in a couple of seconds when some frames are lost.
In order to reproduce the problem, please try the following program on linux-2.6.25.*
Setup some iptables rules to allow two frames per second sent on loopback interface to tcp destination port 12000
iptables -N SLOWLO
iptables -A SLOWLO -m hashlimit --hashlimit 2 --hashlimit-burst 1 --hashlimit-mode dstip --hashlimit-name slow2 -j ACCEPT
iptables -A SLOWLO -j DROP
iptables -A OUTPUT -o lo -p tcp --dport 12000 -j SLOWLO
Then run the attached program and see the output :
# ./loop

It isn't helping anything and we aren't going to be able to change all
the drivers that do queue wakeups in strange situations.
Just letting a noop_qdisc get scheduled will work because when
qdisc_run() executes via net_tx_work() it will simply find no packets
pending when it makes the ->dequeue() call in qdisc_restart.

I/OAT DMA performance tuning showed different optimal values of
tcp_dma_copybreak for different I/OAT versions (4096 for 1.2 and 2048
for 2.0). This patch lets ioatdma driver set tcp_dma_copybreak value
according to these results.

As reported by Alexey Dobriyan:
CHECK net/ipv4/tcp_output.c
net/ipv4/tcp_output.c:475:7: warning: dubious: !x & y
And sparse is damn right!
if (unlikely(!OPTION_TS & opts->options))
^^^
size += TCPOLEN_SACKPERM_ALIGNED;
OPTION_TS is (1 << 1), so condition will never trigger.

This patch clamps the cscov setsockopt values to a maximum of 0xFFFF.
Setsockopt values greater than 0xffff can cause an unwanted
wrap-around. Further, IPv6 jumbograms are not supported (RFC 3838,
3.5), so that values greater than 0xffff are not even useful.
Further changes: fixed a typo in the documentation.

As suggested by Dave:
This patch adds a function to get the driver name from a struct net_device,
and consequently uses this in the watchdog timeout handler to print as
part of the message.

Minor nit, use size_t for allocation size and kcalloc to allocate
an array. Probably makes no actual code difference.

This fixes the bridge reference count problem and cleanups ipv6 FIB
timer management. Don't use expires field, because it is not a proper
way to test, instead use timer_pending().
