From Andrey Vagin. 2) VMWARE VM VSOCK layer, from Andy King. 3) Much improved support for virtual functions and SR-IOV in bnx2x, from Ariel ELior. 4) All protocols on ipv4 and ipv6 are now network namespace aware, and all the compatability checks for initial-namespace-only protocols is removed. Thanks to Tom Parkin for helping deal with the last major holdout, L2TP. 5) IPV6 support in netpoll and network namespace support in pktgen, from Cong Wang. 6) Multiple Registration Protocol (MRP) and Multiple VLAN Registration Protocol (MVRP) support, from David Ward. 7) Compute packet lengths more accurately in the packet scheduler, from Eric Dumazet. 8) Use per-task page fragment allocator in skb_append_datato_frags(), also from Eric Dumazet. 9) Add support for connection tracking labels in netfilter, from Florian Westphal. 10) Fix default multicast group joining on ipv6, and add anti-spoofing checks to 6to4 and 6rd. 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. Although this still needs some minor bug fixing before it's %100 correct in all cases. 17) Handle unresolved IPSEC states like ARP, with a resolution packet queue. 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() ...
| * | | net: phy: remove flags argument from phy_{attach, connect, connect_direct}Florian Fainelli2013-01-141-2/+2
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The flags argument of the phy_{attach,connect,connect_direct} functions is then used to assign a struct phy_device dev_flags with its value. All callers but the tg3 driver pass the flag 0, which results in the underlying PHY drivers in drivers/net/phy/ not being able to actually use any of the flags they would set in dev_flags. This patch gets rid of the flags argument, and passes phydev->dev_flags to the internal PHY library call phy_attach_direct() such that drivers which actually modify a phy device dev_flags get the value preserved for use by the underlying phy driver.

That commit causes two kinds of breakage; it breaks registration of AMBA devices when one of the parent nodes already contains overlapping resource regions, and it breaks calls to request_region() by device drivers in certain conditions where there are overlapping memory regions. Both of these problems can probably be fixed, but it is better to back out the commit and get a proper fix designed before trying again. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch creates of_count_phandle_with_args(), a new function for counting the number of phandle+argument tuples in a given property.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of_get_next_available_child() acquires devtree_lock, then calls of_device_is_available() which calls of_get_property() which calls of_find_property() which tries to re-acquire devtree_lock, thus causing deadlock. To avoid this, create a new __of_device_is_available() which calls __of_get_property() instead, which calls __of_find_property(), which does not take the lock,. Update of_get_next_available_child() to call the new __of_device_is_available() since it already owns the lock.

The previous cleanup and this conversion were originally separate since they predated when mainline got raw spinlock (in commit c2f21ce2e31286a "locking: Implement new raw_spinlock"). So, at that point in time, the cleanup was considered plausible for mainline, but not this conversion. In any case, we've kept them separate as it makes for easier review and better bisection.

It even could be a mutex, but unfortunately it's locked from cpu hotplug paths which can't schedule :( So it needs to become a raw lock on rt as well. The devtree_lock would be the only user of a raw_rw_lock, so we are better off cleaning up the recursive locking paths which allows us to convert devtree_lock to a read_lock. Here we do the standard thing of introducing __foo() as the "raw" version of foo(), so that we can take better control of the locking. The "raw" versions are not exported and are for internal use within the file itself.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The of_find_matching_node_and_match() function incorrectly sets the matched entry to 'matches' when the compatible value of a node matches one of the possible values.

At a minimum this fills in proc/iomem and presumably makes resource tracking and conflict detection work better. However, it has the side effect of moving all OF generated platform devices from /sys/devices to /sys/devices/platform/. It /shouldn't/ break userspace because userspace is not supposed to depend on the full path (because userspace always does what it is supposed to, right?). This may cause breakage if either: 1) any two nodes in a given device tree have overlapping & staggered regions (ie. 0x80..0xbf and 0xa0..0xdf; where one is not contained within the other). In this case one of the devices will fail to register and an exception will be needed in platform_device_add() to complain but not fail. 2) any device calls request_mem_region() on a region larger than specified in the device tree. In this case the device node may be wrong, or the driver is overreaching. In either case I'd like to know about any problems and fix them. Please test. Despite the above, I'm still fairly confident that this patch is in good shape. I'd like to put it into linux-next, but would appreciate some bench testing from others before I do; particularly on PowerPC machines. v2: Remove powerpc special-case Cc: Jason Gunthorpe <jgunthorpe@obsidianresearch.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Rob Herring <rob.herring@calxeda.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some situations, userspace may want to resolve a device by function and logical number (ie, "serial0") rather than by the base address or full device path. Being able to resolve a device by alias frees userspace from the burden of otherwise having to maintain a mapping between device addresses and their logical assignments on each platform when multiple instances of the same hardware block are present in the system. Although the uevent device attribute contains devicetree compatible information and the full device path, the uevent does not list the alises that may have been defined for the device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for specifying a generic "wakeup-source" property on i2c clients, which will set the I2C_CLIENT_WAKE flag, thus configuring the device to wake the system from suspend (via IRQ). This obviously doesn't make sense on devices lacking IRQ, but since we still allow that in the i2c_board_info case, I don't see a reason to restrict it here. Note: Since the generic i2c bindings aren't documented in the kernel, I didn't find a good place to add documentation for this binding extension. I still think it makes sense to have a generic property instead of having each device do its own binding for the same.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a bus specifies #address-cells > 2, of_bus_default_map() now assumes that the mapping isn't for a physical address but rather an identifier that needs to match exactly. This is required by bindings that use multiple cells to translate a resource to the parent bus (device index, type, ...).

One example is a node that's used to collect a number of non-memory-mapped devices. In that scenario, there may be multiple child nodes with the same name (type) thus necessitating the use of unit addresses in node names, and reg properties: / { regulators { compatible = "simple-bus"; #address-cells = <1>; #size-cells = <0>; regulator@0 { compatible = "regulator-fixed"; reg = <0>; ... }; regulator@1 { compatible = "regulator-fixed"; reg = <1>; ... }; ... }; }; However, #size-cells=0 prevents translation of reg property values into the parent node's address space. In turn, this triggers the kernel to emit error messages during boot, such as: prom_parse: Bad cell count for /regulators/regulator@0 To prevent printing these error messages for legitimate DT content, a number of changes are made: 1) of_get_address()/of_get_pci_address() are modified only to validate the value of #address-cells, and not #size-cells. 2) of_can_translate_address() is added to indicate whether address translation is possible. 3) of_device_make_bus_id() is modified to name devices based on the translated address only where possible, and otherwise fall back to using the (first cell of the) raw untranslated address. 4) of_device_alloc() is modified to create memory resources for a device only if the address can be translated into the CPU's address space.
