2013-06-28reservation: cross-device reservation support, v4Maarten Lankhorst
This adds support for a generic reservations framework that can be hooked up to ttm and dma-buf and allows easy sharing of reservations across devices. The idea is that a dma-buf and ttm object both will get a pointer to a struct reservation_object, which has to be reserved before anything is done with the contents of the dma-buf. Changes since v1: - Fix locking issue in ticket_reserve, which could cause mutex_unlock to be called too many times. Changes since v2: - All fence related calls and members have been taken out for now, what's left is the bare minimum to be useful for ttm locking conversion. Changes since v3: - Removed helper functions too. The documentation has an example implementation for locking. With the move to ww_mutex there is no need to have much logic any more.

2013-06-27acpi-cpufreq: Add new sysfs attribute freqdomain_cpusLan Tianyu
Commits fcf8058 (cpufreq: Simplify cpufreq_add_dev()) and aa77a52 (cpufreq: acpi-cpufreq: Don't set policy->related_cpus from .init()) changed the contents of the "related_cpus" sysfs attribute on systems where acpi-cpufreq is used and user space can't get the list of CPUs which are in the same hardware coordination CPU domain (provided by the ACPI AML method _PSD) via "related_cpus" any more. To make up for that loss add a new sysfs attribute "freqdomian_cpus" for the acpi-cpufreq driver which exposes the list of CPUs in the same domain regardless of whether it is coordinated by hardware or software.

2013-06-27Add support for GMT G762/G763 PWM fan controllersArnaud Ebalard
GMT G762/763 fan speed PWM controller is connected directly to a fan and performs closed-loop or open-loop control of the fan speed. Two modes - PWM or DC - are supported by the chip. Introduced driver provides various knobs to control the operations of the chip (via sysfs interface). Specific characteristics of the system can be passed either using board init code or via DT. Documentation for both the driver and DT bindings are also provided.

Pull networking fixes from David Miller: 1) Found via trinity: If you connect up an ipv6 socket to an ipv4 mapped address then an ipv6 one, sendmsg() can croak because ip6_sk_dst_check() assumes the route cached in the socket is an ipv6 one. In this case there is an ipv4 route attached, so it gets stomped on. Reported by Dave Jones and Hannes Frederic Sowa, fixed by Eric Dumazet. 2) AF_KEY notifications leak some kernel memory to userspace, fix from Mathias Krause. 3) DLCI calls __dev_get_by_name() without proper locking, and dlci_del doesn't validate that the device being deleted is actually a DLCI one. Fixes from Li Zefan. 4) Length check on bluetooth l2cap information responses is wrong, each response type has a different lenth, so we should make sure it's in a given range rather than enforce one single valid length. From Jaganath Kanakkassery. 5) Receive FIFO overflow is really easy to trigger in stress scenerios in the sh_eth driver, but the event isn't being handled properly at all. Specifically, the mask of error interrupts doesn't include the event so we never clear it, resulting in the driver becomming wedged processing an interrupt that never gets cleared. Fix from Sergei Shtylyov. 6) qlcnic sleeps while holding a spinlock, use mdelay() instead of msleep(). From Shahed Shaikh. 7) Missing curly braces causes SIP netfilter NAT module to always drop packets. Fix from Balazs Peter Odor. 8) ipt_ULOG in netfilter passes the wrong value to timer setup, causing the timer to dereference crap when it fires. Fix from Gao Feng. 9) Missing RCU protection around txq->axq_acq traversal in ath_txq_schedule(). Fix from Felix Fietkau. 10) Idle state transition test in ath9k_htc_config() is reversed, fix from Sujith Manoharan. 11) IPV6 forwarding handles unicast Router Alert packets incorrectly. It tests the wrong option state. Previously opt->ra being non-zero indicated a router alert marking in the SKB, but now it's indicated by a bit in opt->flags. Fix from YOSHIFUJI Hideaki. 12) SKB leak in GRE tunnel GSO handling, from Eric Dumazet. 13) get_user_pages_fast() error handling in TUN and MACVTAP use the same local variable for the base index and the loop iterator for page traversal, oops! Fix from Michael S Tsirkin. 14) ipv6_get_lladdr() can fail, and we must therefore check it's return value in inet6_set_iftoken(). For from Hannes Frederic Sowa. 15) If you change an interface name and meanwhile can sneak in something that looks up the name (like SO_BINDTODEVICE or SIOCGIFNAME) we can deadlock with CONFIG_PREEMPT=n. Fix this by providing a helper function that properly uses raw_seqcount_begin(). From Nicolas Schichan. 16) Chain noise calibration test is inverted in iwlwifi, fix from Nikolay Martynov. 17) Properly set TX iwlwifi descriptor flags for back requests. Fix from Emmanuel Grumbach. 18) We can't assume skb_transport_header() is set in xt_TCPOPTSTRAP module, fix from Pablo Neira Ayuso. 19) Some crummy APs don't provide the proper High Throughput info in association response frames. Add a workaround by assume we'll use whatever is in the beacon/probe. Fix from Johannes Berg. 20) mac80211 call to rate_idx_match_mask() swaps two arguments (mask and channel width). Fix from Simon Wunderlich. 21) xt_TCPMSS (like xt_TCPOPTSTRAP) must not try to handle fragmented frames. Fix from Phil Oester. 22) Fix rate control regression causing iwlwifi/iwlegacy chips to use 1Mbit/s on pre-11n networks. From Moshe Benji and Stanslaw Gruszka. 23) Disable brcmsmac power-save functions, they cause regressions. From Arend van Spriel. 24) Enforce a sane minimum MTU in l2cap_build_cmd() otherwise we can easily crash. Fix from Anderson Lizardo. 25) If a learning packet arrives during vxlan_stop() we crash, easily fixed by checking netif_running(). From Stephen Hemminger. 26) Static vxlan FDB entries should not be migrated, also from Stephen. 27) skb_clone() failures not handled in vxlan_xmit(), oops. Also from Stephen. 28) Add minimal driver for AR816x/AR817x ethernet chips, from Johannes Berg. 29) Fix regression in userspace VLAN acceleration control, added by the 802.1ad support changes. Fix from Fernando Luis Vazquez Cao. 30) Interval selection for MLD queries in the bridging code was reversed. Fix from Linus Lüssing. 31) ipv6's ndisc_send_redirect() erroneously writes to the packet we received not the packet we are building to send out. Fix from Matthias Schiffer. 32) Don't free netdev before unregistering it, in usb_8dev can driver. From Marc Kleine-Budde. 33) Fix nl80211 attribute buffer races, from Johannes Berg. 34) Although netlink_diag.h is under uapi/ it isn't present in Kbuild. From Stephen Hemminger. 35) Wrong address and family passed to MD5 key lookups in TCP, from Aydin Arik. 36) phy_type attribute created by SFC driver should not be writable. From Ben Hutchings. 37) Receive/Transmit queue allocations in pxa168_eth and mv643xx_eth should use kzalloc(). Otherwise if setup fails half-way, we'll dereference garbage when trying to teardown the rings. From Lubomir Rintel. 38) Fix double-allocation of dst (resulting in unfreeable net device) in ipv6's init_loopback(). From Gao Feng. 39) Fix fragmentation handling SKB leak in netfilter conntrack, we were freeing the wrong skb pointer. From Phil Oester. 40) Don't report "-1" (SPEED_UNKNOWN) in bond_miimon_commit(), from Nikolay Aleksandrov. 41) davinci_cpdma doesn't check for DMA mapping errors, letting the device scribble to random addresses.

2013-06-26mutex: Add support for wound/wait style locksMaarten Lankhorst
Wound/wait mutexes are used when other multiple lock acquisitions of a similar type can be done in an arbitrary order. The deadlock handling used here is called wait/wound in the RDBMS literature: The older tasks waits until it can acquire the contended lock. The younger tasks needs to back off and drop all the locks it is currently holding, i.e. the younger task is wounded. For full documentation please read Documentation/ww-mutex-design.txt.

MD: Remember the last sync operation that was performed This patch adds a field to the mddev structure to track the last sync operation that was performed. This is especially useful when it comes to what is recorded in mismatch_cnt in sysfs. If the last operation was "data-check", then it reports the number of descrepancies found by the user-initiated check. If it was a "repair" operation, then it is reporting the number of descrepancies repaired. etc. Signed-off-by: Jonathan Brassow <jbrassow@redhat.com> Signed-off-by: NeilBrown <neilb@suse.de>
2013-06-25bonding: add an option to fail when any of arp_ip_target is inaccessibleVeaceslav Falico
Currently, we fail only when all of the ips in arp_ip_target are gone. However, in some situations we might need to fail if even one host from arp_ip_target becomes unavailable. All situations, obviously, rely on the idea that we need *completely* functional network, with all interfaces/addresses working correctly. One real world example might be: vlans on top on bond (hybrid port). If bond and vlans have ips assigned and we have their peers monitored via arp_ip_target - in case of switch misconfiguration (trunk/access port), slave driver malfunction or tagged/untagged traffic dropped on the way - we will be able to switch to another slave. Though any other configuration needs that if we need to have access to all arp_ip_targets. This patch adds this possibility by adding a new parameter - arp_all_targets (both as a module parameter and as a sysfs knob). It can be set to: 0 or any (the default) - which works exactly as it's working now - the slave is up if any of the arp_ip_targets are up. 1 or all - the slave is up if all of the arp_ip_targets are up. This parameter can be changed on the fly (via sysfs), and requires the mode to be active-backup and arp_validate to be enabled (it obeys the arp_validate config on which slaves to validate). Internally it's done through: 1) Add target_last_arp_rx[BOND_MAX_ARP_TARGETS] array to slave struct. It's an array of jiffies, meaning that slave->target_last_arp_rx[i] is the last time we've received arp from bond->params.arp_targets[i] on this slave. 2) If we successfully validate an arp from bond->params.arp_targets[i] in bond_validate_arp() - update the slave->target_last_arp_rx[i] with the current jiffies value. 3) When getting slave's last_rx via slave_last_rx(), we return the oldest time when we've received an arp from any address in bond->params.arp_targets[]. If the value of arp_all_targets == 0 - we still work the same way as before. Also, update the documentation to reflect the new parameter. v3->v4: Kill the forgotten rtnl_unlock(), rephrase the documentation part to be more clear, don't fail setting arp_all_targets if arp_validate is not set - it has no effect anyway but can be easier to set up. Also, print a warning if the last arp_ip_target is removed while the arp_interval is on, but not the arp_validate. v2->v3: Use _bh spinlock, remove useless rtnl_lock() and use jiffies for new arp_ip_target last arp, instead of slave_last_rx(). On bond_enslave(), use the same initialization value for target_last_arp_rx[] as is used for the default last_arp_rx, to avoid useless interface flaps. Also, instead of failing to remove the last arp_ip_target just print a warning - otherwise it might break existing scripts. v1->v2: Correctly handle adding/removing hosts in arp_ip_target - we need to shift/initialize all slave's target_last_arp_rx. Also, don't fail module loading on arp_all_targets misconfiguration, just disable it, and some minor style fixes. Signed-off-by: Veaceslav Falico <vfalico@redhat.com> Signed-off-by: David S.

2013-06-25net: poll/select low latency socket supportEliezer Tamir
select/poll busy-poll support. Split sysctl value into two separate ones, one for read and one for poll. updated Documentation/sysctl/net.txt Add a new poll flag POLL_LL. When this flag is set, sock_poll will call sk_poll_ll if possible. sock_poll sets this flag in its return value to indicate to select/poll when a socket that can busy poll is found. When poll/select have nothing to report, call the low-level sock_poll again until we are out of time or we find something. Once the system call finds something, it stops setting POLL_LL, so it can return the result to the user ASAP. Signed-off-by: Eliezer Tamir <eliezer.tamir@linux.intel.com> Signed-off-by: David S.

2013-06-25Merge branch 'sti/soc' into next/lateOlof Johansson
From Srinivas Kandagatla <srinivas.kandagatla@st.com>: This patch-set adds basic support for STMicroelectronics STi series SOCs which includes STiH415 and STiH416 with B2000 and B2020 board support. STiH415 and STiH416 are dual-core ARM Cortex-A9 CPU, designed for use in Set-top-boxes. The SOC support is available in mach-sti which contains support code for STiH415, STiH416 SOCs including the generic board support. The reason for adding two SOCs at this patch set is to show that no new C code is required for second SOC(STiH416) support. * sti/soc: ARM: stih41x: Add B2020 board support ARM: stih41x: Add B2000 board support ARM: sti: Add DEBUG_LL console support ARM: sti: Add STiH416 SOC support ARM: sti: Add STiH415 SOC support Signed-off-by: Olof Johansson <olof@lixom.net>
