2009-11-029p: fix readdir corner casesEric Van Hensbergen1-4/+3
The patch below also addresses a couple of other corner cases in readdir seen with a large (e.g. 64k) msize. I'm not sure what people think of my co-opting of fid->aux here. I'd be happy to rework if there's a better way. When the size of the user supplied buffer passed to readdir is smaller than the data returned in one go by the 9P read request, v9fs_dir_readdir() currently discards extra data so that, on the next call, a 9P read request will be issued with offset < previous offset + bytes returned, which voilates the constraint described in paragraph 3 of read(5) description. This patch preseves the leftover data in fid->aux for use in the next call. Signed-off-by: Jim Garlick <garlick@llnl.gov> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

2009-10-12mac80211: document ieee80211_rx() context requirementJohannes Berg1-0/+2
ieee80211_rx() must be called with softirqs disabled since the networking stack requires this for netif_rx() and some code in mac80211 can assume that it can not be processing its own tasklet and this call at the same time. It may be possible to remove this requirement after a careful audit of mac80211 and doing any needed locking improvements in it along with disabling softirqs around netif_rx(). An alternative might be to push all packet processing to process context in mac80211, instead of to the tasklet, and add other synchronisation.

2009-09-239p: Add fscache support to 9pAbhishek Kulkarni1-0/+3
This patch adds a persistent, read-only caching facility for 9p clients using the FS-Cache caching backend. When the fscache facility is enabled, each inode is associated with a corresponding vcookie which is an index into the FS-Cache indexing tree. The FS-Cache indexing tree is indexed at 3 levels: - session object associated with each mount. - inode/vcookie - actual data (pages) A cache tag is chosen randomly for each session. These tags can be read off /sys/fs/9p/caches and can be passed as a mount-time parameter to re-attach to the specified caching session.

2009-09-15pkt_sched: Fix tx queue selection in tc_modify_qdiscJarek Poplawski1-1/+1
After the recent mq change there is the new select_queue qdisc class method used in tc_modify_qdisc, but it works OK only for direct child qdiscs of mq qdisc. Grandchildren always get the first tx queue, which would give wrong qdisc_root etc. results (e.g. for sch_htb as child of sch_prio). This patch fixes it by using parent's dev_queue for such grandchildren qdiscs. The select_queue method's return type is changed BTW.

2009-09-15bonding: remap muticast addresses without using dev_close() and dev_open()Moni Shoua1-0/+2
This patch fixes commit e36b9d16c6a6d0f59803b3ef04ff3c22c3844c10. The approach there is to call dev_close()/dev_open() whenever the device type is changed in order to remap the device IP multicast addresses to HW multicast addresses. This approach suffers from 2 drawbacks: *. It assumes tha the device is UP when calling dev_close(), or otherwise dev_close() has no affect. It is worth to mention that initscripts (Redhat) and sysconfig (Suse) doesn't act the same in this matter. *. dev_close() has other side affects, like deleting entries from the routing table, which might be unnecessary. The fix here is to directly remap the IP multicast addresses to HW multicast addresses for a bonding device that changes its type, and nothing else.

2009-09-09net_sched: fix estimator lock selection for mq child qdiscsPatrick McHardy1-0/+1
When new child qdiscs are attached to the mq qdisc, they are actually attached as root qdiscs to the device queues. The lock selection for new estimators incorrectly picks the root lock of the existing and to be replaced qdisc, which results in a use-after-free once the old qdisc has been destroyed. Mark mq qdisc instances with a new flag and treat qdiscs attached to mq as children similar to regular root qdiscs. Additionally prevent estimators from being attached to the mq qdisc itself since it only updates its byte and packet counters during dumps.

This patch adds a classful dummy scheduler which can be used as root qdisc for multiqueue devices and exposes each device queue as a child class. This allows to address queues individually and graft them similar to regular classes. Additionally it presents an accumulated view of the statistics of all real root qdiscs in the dummy root. Two new callbacks are added to the qdisc_ops and qdisc_class_ops: - cl_ops->select_queue selects the tx queue number for new child classes. - qdisc_ops->attach() overrides root qdisc device grafting to attach non-shared qdiscs to the queues.

2009-09-04sctp: Sysctl configuration for IPv4 Address ScopingBhaskar Dutta2-0/+17
This patch introduces a new sysctl option to make IPv4 Address Scoping configurable <draft-stewart-tsvwg-sctp-ipv4-00.txt>. In networking environments where DNAT rules in iptables prerouting chains convert destination IP's to link-local/private IP addresses, SCTP connections fail to establish as the INIT chunk is dropped by the kernel due to address scope match failure. For example to support overlapping IP addresses (same IP address with different vlan id) a Layer-5 application listens on link local IP's, and there is a DNAT rule that maps the destination IP to a link local IP. Such applications never get the SCTP INIT if the address-scoping draft is strictly followed. This sysctl configuration allows SCTP to function in such unconventional networking environments. Sysctl options: 0 - Disable IPv4 address scoping draft altogether 1 - Enable IPv4 address scoping (default, current behavior) 2 - Enable address scoping but allow IPv4 private addresses in init/init-ack 3 - Enable address scoping but allow IPv4 link local address in init/init-ack Signed-off-by: Bhaskar Dutta <bhaskar.dutta@globallogic.com> Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>

2009-09-04sctp: Fix SCTP_MAXSEG socket option to comply to spec.Vlad Yasevich2-3/+5
We had a bug that we never stored the user-defined value for MAXSEG when setting the value on an association. Thus future PMTU events ended up re-writing the frag point and increasing it past user limit. Additionally, when setting the option on the socket/endpoint, we effect all current associations, which is against spec. Now, we store the user 'maxseg' value along with the computed 'frag_point'. We inherit 'maxseg' from the socket at association creation and use it as an upper limit for 'frag_point' when its set. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>
2009-09-04sctp: Don't do NAGLE delay on large writes that were fragmented smallVlad Yasevich1-1/+1
SCTP will delay the last part of a large write due to NAGLE, if that part is smaller then MTU. Since we are doing large writes, we might as well send the last portion now instead of waiting untill the next large write happens. The small portion will be sent as is regardless, so it's better to not delay it. This is a result of much discussions with Wei Yongjun <yjwei@cn.fujitsu.com> and Doug Graham <dgraham@nortel.com>.

2009-09-04sctp: drop a_rwnd to 0 when receive buffer overflows.Vlad Yasevich1-0/+6
SCTP has a problem that when small chunks are used, it is possible to exhaust the receiver buffer without fully closing receive window. This happens due to all overhead that we have account for with small messages. To fix this, when receive buffer is exceeded, we'll drop the window to 0 and save the 'drop' portion. When application starts reading data and freeing up recevie buffer space, we'll wait until we've reached the 'drop' window and then add back this 'drop' one mtu at a time. This worked well in testing and under stress produced rather even recovery. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>
2009-09-04sctp: Send user messages to the lower layer as oneVlad Yasevich2-0/+4
Currenlty, sctp breaks up user messages into fragments and sends each fragment to the lower layer by itself. This means that for each fragment we go all the way down the stack and back up. This also discourages bundling of multiple fragments when they can fit into a sigle packet (ex: due to user setting a low fragmentation threashold). We introduce a new command SCTP_CMD_SND_MSG and hand the whole message down state machine. The state machine and the side-effect parser will cork the queue, add all chunks from the message to the queue, and then un-cork the queue thus causing the chunks to get transmitted.

2009-09-04sctp: Disallow new connection on a closing socketVlad Yasevich1-1/+1
If a socket has a lot of association that are in the process of of being closed/aborted, it is possible for a remote to establish new associations during the time period that the old ones are shutting down. If this was a result of a close() call, there will be no socket and will cause a memory leak. We'll prevent this by setting the socket state to CLOSING and disallow new associations when in this state. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>

But fact is, the original GFP_KERNEL also sleeps. GFP_ATOMIC+yield() looks weird, but it is no worse the implicit sleep inside GFP_KERNEL. Both could loop endlessly under memory pressure.

2009-09-01Revert Backoff [v3]: Calculate TCP's connection close threshold as a time value.Damian Lukowski1-0/+18
RFC 1122 specifies two threshold values R1 and R2 for connection timeouts, which may represent a number of allowed retransmissions or a timeout value. Currently linux uses sysctl_tcp_retries{1,2} to specify the thresholds in number of allowed retransmissions. For any desired threshold R2 (by means of time) one can specify tcp_retries2 (by means of number of retransmissions) such that TCP will not time out earlier than R2. This is the case, because the RTO schedule follows a fixed pattern, namely exponential backoff. However, the RTO behaviour is not predictable any more if RTO backoffs can be reverted, as it is the case in the draft "Make TCP more Robust to Long Connectivity Disruptions" (http://tools.ietf.org/html/draft-zimmermann-tcp-lcd). In the worst case TCP would time out a connection after 3.2 seconds, if the initial RTO equaled MIN_RTO and each backoff has been reverted. This patch introduces a function retransmits_timed_out(N), which calculates the timeout of a TCP connection, assuming an initial RTO of MIN_RTO and N unsuccessful, exponentially backed-off retransmissions. Whenever timeout decisions are made by comparing the retransmission counter to some value N, this function can be used, instead. The meaning of tcp_retries2 will be changed, as many more RTO retransmissions can occur than the value indicates. However, it yields a timeout which is similar to the one of an unpatched, exponentially backing off TCP in the same scenario. As no application could rely on an RTO greater than MIN_RTO, there should be no risk of a regression.

2009-09-01Revert Backoff [v3]: Revert RTO on ICMP destination unreachableDamian Lukowski1-0/+12
Here, an ICMP host/network unreachable message, whose payload fits to TCP's SND.UNA, is taken as an indication that the RTO retransmission has not been lost due to congestion, but because of a route failure somewhere along the path. With true congestion, a router won't trigger such a message and the patched TCP will operate as standard TCP. This patch reverts one RTO backoff, if an ICMP host/network unreachable message, whose payload fits to TCP's SND.UNA, arrives. Based on the new RTO, the retransmission timer is reset to reflect the remaining time, or - if the revert clocked out the timer - a retransmission is sent out immediately. Backoffs are only reverted, if TCP is in RTO loss recovery, i.e. if there have been retransmissions and reversible backoffs, already. Changes from v2: 1) Renaming of skb in tcp_v4_err() moved to another patch. 2) Reintroduced tcp_bound_rto() and __tcp_set_rto(). 3) Fixed code comments.
