2012-02-08af_iucv: allow retrieval of maximum message sizeUrsula Braun
For HS transport the maximum message size depends on the MTU-size of the HS-device bound to the AF_IUCV socket. This patch adds a getsockopt option MSGSIZE returning the maximum message size that can be handled for this AF_IUCV socket.

2012-02-08af_iucv: change net_device handling for HS transportUrsula Braun
This patch saves the net_device in the iucv_sock structure during bind in order to fasten skb sending. In addition some other small improvements are made for HS transport: - error checking when sending skbs - locking changes in afiucv_hs_callback_txnotify - skb freeing in afiucv_hs_callback_txnotify And finally it contains code cleanup to get rid of iucv_skb_queue_purge.

2012-02-08ipv4: Implement IP_UNICAST_IF socket option.Erich E. Hoover
The IP_UNICAST_IF feature is needed by the Wine project. This patch implements the feature by setting the outgoing interface in a similar fashion to that of IP_MULTICAST_IF. A separate option is needed to handle this feature since the existing options do not provide all of the characteristics required by IP_UNICAST_IF, a summary is provided below. SO_BINDTODEVICE: * SO_BINDTODEVICE requires administrative privileges, IP_UNICAST_IF does not. From reading some old mailing list articles my understanding is that SO_BINDTODEVICE requires administrative privileges because it can override the administrator's routing settings. * The SO_BINDTODEVICE option restricts both outbound and inbound traffic, IP_UNICAST_IF only impacts outbound traffic. IP_PKTINFO: * Since IP_PKTINFO and IP_UNICAST_IF are independent options, implementing IP_UNICAST_IF with IP_PKTINFO will likely break some applications. * Implementing IP_UNICAST_IF on top of IP_PKTINFO significantly complicates the Wine codebase and reduces the socket performance (doing this requires a lot of extra communication between the "server" and "user" layers). bind(): * bind() does not work on broadcast packets, IP_UNICAST_IF is specifically intended to work with broadcast packets. * Like SO_BINDTODEVICE, bind() restricts both outbound and inbound traffic.

2012-02-07net/sched: sch_plug - Queue traffic until an explicit release commandShriram Rajagopalan
The qdisc supports two operations - plug and unplug. When the qdisc receives a plug command via netlink request, packets arriving henceforth are buffered until a corresponding unplug command is received. Depending on the type of unplug command, the queue can be unplugged indefinitely or selectively. This qdisc can be used to implement output buffering, an essential functionality required for consistent recovery in checkpoint based fault-tolerance systems. Output buffering enables speculative execution by allowing generated network traffic to be rolled back. It is used to provide network protection for Xen Guests in the Remus high availability project, available as part of Xen. This module is generic enough to be used by any other system that wishes to add speculative execution and output buffering to its applications. This module was originally available in the linux 2.6.32 PV-OPS tree, used as dom0 for Xen. For more information, please refer to and Changes in V3: * Removed debug output (printk) on queue overflow * Added TCQ_PLUG_RELEASE_INDEFINITE - that allows the user to use this qdisc, for simple plug/unplug operations. * Use of packet counts instead of pointers to keep track of the buffers in the queue.

This resolution takes the semantics from commit f2933e86ad93, and just makes mtd_block_isbad() return zero (false) if the 'block_isbad' function is NULL. But that also means that now "mtd_can_have_bb()" always returns 0. Now, "mtd_block_markbad()" will obviously return an error if the low-level driver doesn't support bad blocks, so this is somewhat non-symmetric, but it actually makes sense if a NULL "block_isbad" function is considered to mean "I assume that all my blocks are always good".

1) Setting link attributes can modify the size of the attributes that would be reported on a subsequent getlink netlink operation, therefore min_ifinfo_dump_size needs to be adjusted. From Stefan Gula. 2) Resegmentation of TSO frames while trimming can violate invariants expected by callers, namely that the number of segments can only stay the same or decrease, never increase. If MSS changes, however, we can trim data but then end up with more segments. Fix this by only segmenting to the MSS already recorded in the SKB. That's the simplest fix for now and if we want to get more fancy in the future that's a more involved change. This probably explains some retransmit counter inaccuracies. From Neal Cardwell. 3) Fix too-many-wakeups in POLL with AF_UNIX sockets, from Eric Dumazet. 4) Fix CAIF crashes wrt. namespace handling. From Eric Dumazet and Eric W.

2012-01-30net/tcp: Fix tcp memory limits initialization when !CONFIG_SYSCTLGlauber Costa
sysctl_tcp_mem() initialization was moved to sysctl_tcp_ipv4.c in commit 3dc43e3e4d0b52197d3205214fe8f162f9e0c334, since it became a per-ns value. That code, however, will never run when CONFIG_SYSCTL is disabled, leading to bogus values on those fields - causing hung TCP sockets. This patch fixes it by keeping an initialization code in tcp_init(). It will be overwritten by the first net namespace init if CONFIG_SYSCTL is compiled in, and do the right thing if it is compiled out. It is also named properly as tcp_init_mem(), to properly signal its non-sysctl side effect on TCP limits. Reported-by: Ingo Molnar <> Signed-off-by: Glauber Costa <> Cc: David S.

2012-01-29PM / Hibernate: Fix s2disk regression related to freezing workqueuesRafael J. Wysocki
Commit 2aede851ddf08666f68ffc17be446420e9d2a056 PM / Hibernate: Freeze kernel threads after preallocating memory introduced a mechanism by which kernel threads were frozen after the preallocation of hibernate image memory to avoid problems with frozen kernel threads not responding to memory freeing requests. However, it overlooked the s2disk code path in which the SNAPSHOT_CREATE_IMAGE ioctl was run directly after SNAPSHOT_FREE, which caused freeze_workqueues_begin() to BUG(), because it saw that worqueues had been already frozen. Although in principle this issue might be addressed by removing the relevant BUG_ON() from freeze_workqueues_begin(), that would reintroduce the very problem that commit 2aede851ddf08666f68ffc17be4 attempted to avoid into that particular code path. For this reason, to fix the issue at hand, introduce thaw_kernel_threads() and make the SNAPSHOT_FREE ioctl execute it. Special thanks to Srivatsa S. Bhat for detailed analysis of the problem.

2012-01-27netns: Fail conspicously if someone uses net_generic at an inappropriate time.Eric W. Biederman
By definition net_generic should never be called when it can return NULL. Fail conspicously with a BUG_ON to make it clear when people mess up that a NULL return should never happen. Recently there was a bug in the CAIF subsystem where it was registered with register_pernet_device instead of register_pernet_subsys. It was erroneously concluded that net_generic could validly return NULL and that net_assign_generic was buggy (when it was just inefficient).

Davem says: 1) Fix JIT code generation on x86-64 for divide by zero, from Eric Dumazet. 2) tg3 header length computation correction from Eric Dumazet. 3) More build and reference counting fixes for socket memory cgroup code from Glauber Costa. 4) module.h snuck back into a core header after all the hard work we did to remove that, from Paul Gortmaker and Jesper Dangaard Brouer. 5) Fix PHY naming regression and add some new PCI IDs in stmmac, from Alessandro Rubini. 6) Netlink message generation fix in new team driver, should only advertise the entries that changed during events, from Jiri Pirko. 7) SRIOV VF registration and unregistration fixes, and also add a missing PCI ID, from Roopa Prabhu. 8) Fix infinite loop in tx queue flush code of brcmsmac, from Stanislaw Gruszka. 9) ftgmac100/ftmac100 build fix, missing interrupt.h include. 10) Memory leak fix in net/hyperv do_set_mutlicast() handling, from Wei Yongjun. 11) Off by one fix in netem packet scheduler, from Vijay Subramanian. 12) TCP loss detection fix from Yuchung Cheng. 13) TCP reset packet MD5 calculation uses wrong address, fix from Shawn Lu. 14) skge carrier assertion and DMA mapping fixes from Stephen Hemminger. 15) Congestion recovery undo performed at the wrong spot in BIC and CUBIC congestion control modules, fix from Neal Cardwell. 16) Ethtool ETHTOOL_GSSET_INFO is unnecessarily restrictive, from Michał Mirosław. 17) Fix triggerable race in ipv6 sysctl handling, from Francesco Ruggeri. 18) Statistics bug fixes in mlx4 from Eugenia Emantayev. 19) rds locking bug fix during info dumps, from your's truly. * git:// (67 commits) rds: Make rds_sock_lock BH rather than IRQ safe. netprio_cgroup.h: dont include module.h from other includes net: flow_dissector.c missing include linux/export.h team: send only changed options/ports via netlink net/hyperv: fix possible memory leak in do_set_multicast() drivers/net: dsa/mv88e6xxx.c files need linux/module.h stmmac: added PCI identifiers llc: Fix race condition in llc_ui_recvmsg stmmac: fix phy naming inconsistency dsa: Add reporting of silicon revision for Marvell 88E6123/88E6161/88E6165 switches. tg3: fix ipv6 header length computation skge: add byte queue limit support mv643xx_eth: Add Rx Discard and Rx Overrun statistics bnx2x: fix compilation error with SOE in fw_dump bnx2x: handle CHIP_REVISION during init_one bnx2x: allow user to change ring size in ISCSI SD mode bnx2x: fix Big-Endianess in ethtool -t bnx2x: fixed ethtool statistics for MF modes bnx2x: credit-leakage fixup on vlan_mac_del_all macvlan: fix a possible use after free ...
2012-01-24netprio_cgroup.h: dont include module.h from other includesPaul Gortmaker
A considerable effort was invested in wiping out module.h from being present in all the other standard includes. This one leaked back in, but once again isn't strictly necessary, so remove it. Signed-off-by: Paul Gortmaker <> Signed-off-by: David S. Miller <>
2012-01-24team: send only changed options/ports via netlinkJiri Pirko
This patch changes event message behaviour to send only updated records instead of whole list. This fixes bug on which userspace receives non-actual data in case multiple events occur in row. Signed-off-by: Jiri Pirko <> Signed-off-by: David S. Miller <>

2012-01-24NFC: Add NCI multiple targets supportIlan Elias
Add the ability to select between multiple targets in NCI. If only one target is found, it will be auto-activated. If more than one target is found, then DISCOVER_NTF will be generated for each target, and the host should select one by calling DISCOVER_SELECT_CMD. Then, the target will be activated. If the activation fails, GENERIC_ERROR_NTF is generated. Signed-off-by: Ilan Elias <> Signed-off-by: John W. Linville <>
2012-01-24NFC: NFC core layer should not set the target_idxIlan Elias
The NFC core layer should not set the target_idx. Instead, the driver layer (e.g. NCI, PN533) should set the target_idx, so that it will be able to identify the target when its I/F (e.g. activate_target) is called. This is required in order to support multiple targets. Note that currently supported drivers (PN533 and NCI) don't use the target_idx in their implementation.

2012-01-24NFC: Clearly separate NCI states from flagsIlan Elias
Make a clear separation between NCI states and flags. This is required in order to support more NCI states (e.g. for multiple targets support). Signed-off-by: Ilan Elias <> Signed-off-by: John W. Linville <>
