we upgraded the kernel of a nfs-server from 2.6.17.11 to 2.6.22.6. Since
then we get the message
lockd: too many open TCP sockets, consider increasing the number of nfsd threads
lockd: last TCP connect from ^\\236^\É^D
These random characters in the second line are caused by a bug in
svc_tcp_accept.
(Note: there are two previous __svc_print_addr(sin, buf, sizeof(buf))
calls in this function, either of which would initialize buf correctly;
but both are inside "if"'s and are not necessarily executed. This is
less obvious in the second case, which is inside a dprintk(), which is a
macro which expands to an if statement.)

The following patch fixes the handling of netlink packets containing
multiple messages.
As exposed during netfilter workshop, nfnetlink_log was overwritten the
message type of the last message (setting it to MSG_DONE) in a multipart
packet. The consequence was libnfnetlink to ignore the last message in the
packet.
The following patch adds a supplementary message (with type MSG_DONE) af
the end of the netlink skb.

In "[VLAN]: Move device registation to seperate function" (commit
e89fe42cd03c8fd3686df82d8390a235717a66de), a pile of code got moved
to register_vlan_dev(), including grabbing a reference to underlying
device. However, original dev_hold() had been left behind, so we
leak a reference to net_device now...

This patch adds an optimised version of skb_cow that avoids the copy if
the header can be modified even if the rest of the payload is cloned.
This can be used in encapsulating paths where we only need to modify the
header. As it is, this can be used in PPPOE and bridging.

Since the sctp_sockaddr_entry is now RCU enabled as part of
the patch to synchronize sctp_localaddr_list, it makes sense to
change all handling of these entries to RCU. This includes the
sctp_bind_addrs structure and it's list of bound addresses.
This list is currently protected by an external rw_lock and that
looks like an overkill. There are only 2 writers to the list:
bind()/bindx() calls, and BH processing of ASCONF-ACK chunks.
These are already seriealized via the socket lock, so they will
not step on each other. These are also relatively rare, so we
should be good with RCU.
The readers are varied and they are easily converted to RCU.

sctp_localaddr_list is modified dynamically via NETDEV_UP
and NETDEV_DOWN events, but there is not synchronization
between writer (even handler) and readers. As a result,
the readers can access an entry that has been freed and

The commit 95c385 broke proper source address selection for cases in which
there is a address which is makred 'deprecated'. The commit mistakenly
changed ifa->flags to ifa_result->flags (probably copy/paste error from a

1) Comments suggest that setting optlen to zero will unbind
the socket from whatever device it might be attached to. This
hasn't been the case since at least 2.2.x because the first thing
this function does is return -EINVAL if 'optlen' is less than
sizeof(int).
This check also means that passing in a two byte string doesn't
work so well. It's almost as if this code was testing with "eth?"
patterned strings and nothing else :-)
Fix this by breaking the logic of this facility out into a
seperate function which validates optlen more appropriately.
The optlen==0 and small string cases now work properly.
2) We should reset the cached route of the socket after we have made
the device binding changes, not before.

Commit aaf68cfbf2241d24d46583423f6bff5c47e088b3 added a bias
to sk_inuse, so this test for an unused socket now fails. So no
sockets get closed because they are old (they might get closed
if the client closed them).
This bug has existed since 2.6.21-rc1.

Some of skbs in sk->write_queue do not have skb->dst because
we do not fill skb->dst when we allocate new skb in append_data().
BTW, I think we may not need to (or we should not) increment some stats
when using corking; if 100 sendmsg() (with MSG_MORE) result in 2 packets,
how many should we increment?
If 100, we should set skb->dst for every queued skbs.
If 1 (or 2 (*)), we increment the stats for the first queued skb and
we should just skip incrementing OutDiscards for the rest of queued skbs,
adn we should also impelement this semantics in other places;
e.g., we should increment other stats just once, not 100 times.
*: depends on the place we are discarding the datagram.
I guess should just increment by 1 (or 2).

So I've had a deadlock reported to me. I've found that the sequence of
events goes like this:
1) process A (modprobe) runs to remove ip_tables.ko
2) process B (iptables-restore) runs and calls setsockopt on a netfilter socket,
increasing the ip_tables socket_ops use count
3) process A acquires a file lock on the file ip_tables.ko, calls remove_module
in the kernel, which in turn executes the ip_tables module cleanup routine,
which calls nf_unregister_sockopt
4) nf_unregister_sockopt, seeing that the use count is non-zero, puts the
calling process into uninterruptible sleep, expecting the process using the
socket option code to wake it up when it exits the kernel
4) the user of the socket option code (process B) in do_ipt_get_ctl, calls
ipt_find_table_lock, which in this case calls request_module to load
ip_tables_nat.ko
5) request_module forks a copy of modprobe (process C) to load the module and
blocks until modprobe exits.
6) Process C. forked by request_module process the dependencies of
ip_tables_nat.ko, of which ip_tables.ko is one.
7) Process C attempts to lock the request module and all its dependencies, it
blocks when it attempts to lock ip_tables.ko (which was previously locked in
step 3)
Theres not really any great permanent solution to this that I can see, but I've
developed a two part solution that corrects the problem
Part 1) Modifies the nf_sockopt registration code so that, instead of using a
use counter internal to the nf_sockopt_ops structure, we instead use a pointer
to the registering modules owner to do module reference counting when nf_sockopt
calls a modules set/get routine. This prevents the deadlock by preventing set 4
from happening.
Part 2) Enhances the modprobe utilty so that by default it preforms non-blocking
remove operations (the same way rmmod does), and add an option to explicity
request blocking operation. So if you select blocking operation in modprobe you
can still cause the above deadlock, but only if you explicity try (and since
root can do any old stupid thing it would like.... :) ).

Bug: http://bugzilla.kernel.org/show_bug.cgi?id=8876
Not all ips are shown by "ip addr show" command when IPs number assigned to an
interface is more than 60-80 (in fact it depends on broadcast/label etc
presence on each address).
Steps to reproduce:
It's terribly simple to reproduce:
# for i in $(seq 1 100); do ip ad add 10.0.$i.1/24 dev eth10 ; done
# ip addr show
this will _not_ show all IPs.

msg_iov. Right now the only thing that tries to do so

sufficient to check the total length there and simply

When CONFIG_NET_CLS_ACT is enabled, tc_classify() is called twice in
prio_classify(). This causes "interesting" behaviour: with the setup
below, packets are duplicated, sent twice to ifb0, and then loop in and
out of ifb0.
The patch uses the previously calculated return value in the switch,
which is probably what Patrick had in mind in commit

this will cause "sctp protocol violation state" message print many times.
If SHUTDOWN-ACK is bundled 300 times in one packet, message will be
print 300 times. The same problem also exists when received unexpected
HEARTBEAT-ACK message which is bundled message times.
This patch used net_ratelimit() to suppress error messages print too fast.

PROTOCOL VIOLATION error cause in ABORT is bad encode when make abort
chunk. When SCTP encode ABORT chunk with PROTOCOL VIOLATION error cause,
it just add the error messages to PROTOCOL VIOLATION error cause, the
rest four bytes(struct sctp_paramhdr) is just add to the chunk, not
change the length of error cause. This cause the ABORT chunk to be a bad
format. The chunk is like this:
ABORT chunk
Chunk type: ABORT (6)
Chunk flags: 0x00
Chunk length: 72 (*1)
Protocol violation cause
Cause code: Protocol violation (0x000d)
Cause length: 62 (*2)
Cause information: 5468652063756D756C61746976652074736E2061636B2062...
Cause padding: 0000
[Needless] 00030010
Chunk Length(*1) = 72 but Cause length(*2) only 62, not include the
extend 4 bytes.
((72 - sizeof(chunk_hdr)) = 68) != (62 +3) / 4 * 4

At function sctp_addto_chunk(), it do pad before add payload to chunk if
chunk length is not 4-byte alignment. But it do pad with a bad length.
This patch fixed this probleam.

Currently we only assign the sequence number to a packet that
we are about to transmit. This however breaks the Partial
Reliability extensions, because it's possible for us to
never transmit a packet, i.e. it expires before we get to send
it. In such cases, if the message contained multiple SCTP
fragments, and we did manage to send the first part of the
message, the Stream sequence numbers would get into invalid
state and cause receiver to stall.

When we recieve a FWD-TSN (meaning the peer has abandoned the data),
we need to clean up any partially received messages that may be
hanging out on the re-assembly or re-ordering queues. This is
a MUST requirement that was not properly done before.
