2013-02-23net/core: apply pm_runtime_set_memalloc_noio on network devicesMing Lei1-0/+5
Deadlock might be caused by allocating memory with GFP_KERNEL in runtime_resume and runtime_suspend callback of network devices in iSCSI situation, so mark network devices and its ancestor as 'memalloc_noio' with the introduced pm_runtime_set_memalloc_noio().

Pull s390 update from Martin Schwidefsky: "The most prominent change in this patch set is the software dirty bit patch for s390. It removes __HAVE_ARCH_PAGE_TEST_AND_CLEAR_DIRTY and the page_test_and_clear_dirty primitive which makes the common memory management code a bit less obscure. Heiko fixed most of the PCI related fallout, more often than not missing GENERIC_HARDIRQS dependencies. Notable is one of the 3270 patches which adds an export to tty_io to be able to resize a tty.

From Hannes Frederic Sowa. 11) Make ipv4/ipv6 fragmentation memory limits more reasonable in modern times, rearrange inet frag datastructures for better cacheline locality, and move more operations outside of locking. From Jesper Dangaard Brouer. 12) Instead of strict master <--> slave relationships, allow arbitrary scenerios with "upper device lists". From Jiri Pirko. 13) Improve rate limiting accuracy in TBF and act_police, also from Jiri Pirko. 14) Add a BPF filter netfilter match target, from Willem de Bruijn. 15) Orphan and delete a bunch of pre-historic networking drivers from Paul Gortmaker. 16) Add TSO support for GRE tunnels, from Pravin B SHelar.

From Steffen Klassert. 18) Remove TCP Appropriate Byte Count support (ABC), from Stephen Hemminger. This was long overdue. 19) Support SO_REUSEPORT, from Tom Herbert. 20) Allow locking a socket BPF filter, so that it cannot change after a process drops capabilities. 21) Add VLAN filtering to bridge, from Vlad Yasevich. 22) Bring ipv6 on-par with ipv4 and do not cache neighbour entries in the ipv6 routes, from YOSHIFUJI Hideaki. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1538 commits) ipv6: fix race condition regarding dst->expires and dst->from. net: fix a wrong assignment in skb_split() ip_gre: remove an extra dst_release() ppp: set qdisc_tx_busylock to avoid LOCKDEP splat atl1c: restore buffer state net: fix a build failure when !CONFIG_PROC_FS net: ipv4: fix waring -Wunused-variable net: proc: fix build failed when procfs is not configured Revert "xen: netback: remove redundant xenvif_put" net: move procfs code to net/core/net-procfs.c qmi_wwan, cdc-ether: add ADU960S bonding: set sysfs device_type to 'bond' bonding: fix bond_release_all inconsistencies b44: use netdev_alloc_skb_ip_align() xen: netback: remove redundant xenvif_put net: fec: Do a sanity check on the gpio number ip_gre: propogate target device GSO capability to the tunnel device ip_gre: allow CSUM capable devices to handle packets bonding: Fix initialize after use for 3ad machine state spinlock bonding: Fix race condition between bond_enslave() and bond_3ad_update_lacp_rate() ...

To fix this issue, split 'from' and 'expires' field in dst_entry out of union. Once it is 'from' is assigned in the constructor, keep the reference until the very last stage of the life time of the object. Of course, it is unsafe to change 'from', so make rt6_set_from simple just for fresh entries.

Pull workqueue [delayed_]work_pending() cleanups from Tejun Heo: "This is part of on-going cleanups to remove / minimize usages of workqueue interfaces which are deprecated and/or misleading.

There are a couple legitimate use cases in kernel. Hopefully, they can be converted and [delayed_]work_pending() can be removed completely. Even if not, removing most of misuses should make it more difficult to find examples of misuses and thus slow down growth of them.

John W. Linville says: ==================== One last batch of stragglers intended for 3.9... For the iwlwifi pull, Johannes says: "I hadn't expected to ask you to pull iwlwifi-next again, but I have a number of fixes most of which I'd also send in after rc1, so here it is. The first commit is a merge error between mac80211-next and iwlwifi-next; in addition I have fixes for P2P scanning and MVM driver MAC (virtual interface) management from Ilan, a CT-kill (critical temperature) fix from Eytan, and myself fixed three different little but annoying bugs in the MVM driver. The only ones I might not send for -rc1 are Emmanuel's debug patch, but OTOH it should help greatly if there are any issues, and my own time event debugging patch that I used to find the race condition but we decided to keep it for the future." For the mac80211 pull, Johannes says: "Like iwlwifi-next, this would almost be suitable for rc1. I have a fix for station management on non-TDLS drivers, a CAB queue crash fix for mesh, a fix for an annoying (but harmless) warning, a tracing fix and a documentation fix. Other than that, only a few mesh cleanups." Along with that is a fix for memory corruption in rtlwifi, an orinoco_usb fix to avoid allocating a DMA buffer on the stack, an a hostap fix to return -ENOMEM instead of -1 after a memory allocation failure. The remaining bits implement 802.11ac support for the mwifiex driver -- I think that is still worth getting into 3.9.

Of course, I'm sure there will be a few stragglers here and there...surely a few bug fixes as well... :-) (In fact, I see that Johannes has already queued-up a few more for me while I was preparing this...) Included are a number of pulls... For mac80211-next, Johannes says: "The biggest change I have is undoubtedly Marco's mesh powersave implementation. Beyond that, I have a patch from Emmanuel to modify the DTIM period API in mac80211, scan improvements and a removal of some previous workaround code from Stanislaw, dynamic short slot time from Thomas and 64-bit station byte counters from Vladimir. I also made a number of changes myself, some related to WoWLAN, some auth/deauth improvements and most of them BSS list cleanups." "This time, I have relatively large number of fixes in various areas of the code (a memory leak in regulatory, an RX race in mac80211, the new radar checking caused a P2P device problem, some mesh issues with stations, an older bug in tracing and for kernel-doc) as well as a number of small new features. The biggest (in the diffstat) is my work on hidden SSID tracking." "Please pull to get * radar detection work from Simon * mesh improvements from Thomas * a connection monitoring/powersave fix from Wojciech * TDLS-related station management work from Jouni * VLAN crypto fixes from Michael Braun * CCK support in minstrel_ht from Felix * an SMPS (not SMSP, oops) related improvement in mac80211 (Emmanuel) * some WoWLAN work from Amitkumar Karwar: pattern match offset and a documentation fix * some WoWLAN work from myself (TCP connection wakeup feature API) * and a lot of VHT (and some HT) work (also from myself) And a number of more random cleanups/fixes. I merged mac80211/master to avoid a merge problem there." And regarding iwlwifi-next, Johannes says: "We continue work on our new driver, but I also have a WoWLAN and AP mode improvement for the previous driver and a change to use threaded interrupts to prepare us for working with non-PCIe devices." Regarding wl12xx, Luca says: "A few more patches intended for 3.9. Mostly some clean-ups I've been doing to make it easier to support device-tree. Also including one bug fix for wl12xx where the rates we advertise were wrong and an update in the wlconf structure to support newer firmwares." For the nfc-next bits, Samuel says: "This is the second NFC pull request for 3.9. We have: - A few pn533 fixes on top of Waldemar refactorization of the driver, one of them fixes target mode. - A new driver for Inside Secure microread chipset. It supports two physical layers: i2c and MEI. The MEI one depends on a patchset that's been sent to Greg Kroah-Hartman for inclusion into the 3.9 kernel [1]. The dependency is a KConfig one which means this code is not buildable as long as the MEI API is not usptream." "This 3rd NFC pull request for 3.9 contains a fix for the microread MEI physical layer support, as the MEI bus API changed. From the MEI code, we now pass the MEI id back to the driver probe routine, and we also pass a name and a MEI id table through the mei_bus_driver structure. A few renames as well like e.g. mei_bus_driver to mei_driver or mei_bus_client to mei_device in order to be closer to the driver model practices." For the ath6kl bits, Kalle says: "There's not anything special here, most of the patches are just code cleanup. The only functional changes are using the beacon interval from user space and fixing a crash which happens when inserting and removing the module in a loop." Also, I pulled the wireless tree in order to resolve some pending merge issues. On top of that, there is a bunch of work on brcmfmac that leads up to P2P support. Also, mwifiex, rtlwifi, and a variety of other drivers see some basic cleanups and minor enhancements. Please let me know if there are problems! ==================== Signed-off-by: David S.

This is is the case only for drivers that don't support TDLS, where any kind of change, even just the change of authorized flag that is required for normal operation, was rejected now.

2013-02-15tipc: byte-based overload control on socket receive queueYing Xue1-38/+39
Change overload control to be purely byte-based, using sk->sk_rmem_alloc as byte counter, and compare it to a calculated upper limit for the socket receive queue. For all connection messages, irrespective of message importance, the overload limit is set to a constant value (i.e, 67MB). This limit should normally never be reached because of the lower limit used by the flow control algorithm, and is there only as a last resort in case a faulty peer doesn't respect the send window limit. For datagram messages, message importance is taken into account when calculating the overload limit. The calculation is based on sk->sk_rcvbuf, and is hence configurable via the socket option SO_RCVBUF.

After commit 3c294cb3 "tipc: remove the bearer congestion mechanism", we try to grab the broadcast bearer lock when sending multicast messages over the broadcast link.

Following patch adds GRE protocol offload handler so that skb_gso_segment() can segment GRE packets. SKB GSO CB is added to keep track of total header length so that skb_segment can push entire header. e.g. in case of GRE, skb_segment need to push inner and outer headers to every segment. New NETIF_F_GRE_GSO feature is added for devices which support HW GRE TSO offload. Currently none of devices support it therefore GRE GSO always fall backs to software GSO.
