* rhashtable: don't allocate ht structure on stack in test_rht_initDaniel Borkmann2015-02-201-1/+2
| | | | | | | | | | | | | | | | | | | | | With object runtime debugging enabled, the rhashtable test suite will rightfully throw a warning "ODEBUG: object is on stack, but not annotated" from rhashtable_init(). This is because run_work is (correctly) being initialized via INIT_WORK(), and not annotated by INIT_WORK_ONSTACK(). Meaning, rhashtable_init() is okay as is, we just need to move ht e.g., into global scope. It never triggered anything, since test_rhashtable is rather a controlled environment and effectively runs to completion, so that stack memory is not vanishing underneath us, we shouldn't confuse any testers with it though.

* net/appletalk: LTPC needs virt_to_busArnd Bergmann2015-02-201-1/+1
| | | | | | | | | | | | | | | | | The ltpc driver is rather outdated and does not get built on most platforms because it requires the ISA_DMA_API symbol. However there are some ARM platforms that have ISA_DMA_API but no virt_to_bus, and they get this build error when enabling the ltpc driver. drivers/net/appletalk/ltpc.c: In function 'handlefc': drivers/net/appletalk/ltpc.c:380:2: error: implicit declaration of function 'virt_to_bus' [-Werror=implicit-function-declaration] set_dma_addr(dma,virt_to_bus(ltdmacbuf)); ^ This adds another dependency in Kconfig to avoid that configuration.

* net: smc91x: improve neponset hackArnd Bergmann2015-02-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The smc91x driver tries to support multiple platforms at compile time, but they are mutually exclusive at runtime, and not clearly defined. Trying to build for CONFIG_SA1100_ASSABET without CONFIG_ASSABET_NEPONSET results in this link error: drivers/built-in.o: In function `smc_drv_probe': :(.text+0x33310c): undefined reference to `neponset_ncr_frob' since the neponset_ncr_set function is not defined otherwise. Similarly, building for both CONFIG_SA1100_ASSABET and CONFIG_SA1100_PLEB results in a different build error: smsc/smc91x.c: In function 'smc_drv_probe': smsc/smc91x.c:2299:2: error: implicit declaration of function 'neponset_ncr_set' [-Werror=implicit-function-declaration] neponset_ncr_set(NCR_ENET_OSC_EN); ^ smsc/smc91x.c:2299:19: error: 'NCR_ENET_OSC_EN' undeclared (first use in this function) neponset_ncr_set(NCR_ENET_OSC_EN); ^ This is an attempt to fix the call site responsible for both errors, making sure we call the function exactly when the driver is actually trying to run on the assabet/neponset machine. With this patch, I no longer see randconfig build errors in this file. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S. Miller <davem@davemloft.net>
* sock: sock_dequeue_err_skb() needs hard irq safetyEric Dumazet2015-02-201-2/+3
| | | | | | | | | | | | | Non NAPI drivers can call skb_tstamp_tx() and then sock_queue_err_skb() from hard IRQ context.

* net: Initialize all members in skb_gro_remcsum_init()Geert Uytterhoeven2015-02-201-0/+1
| | | | | | | | | | | | | | | | | | | | | skb_gro_remcsum_init() initializes the gro_remcsum.delta member only, leading to compiler warnings about a possibly uninitialized gro_remcsum.offset member: drivers/net/vxlan.c: In function ‘vxlan_gro_receive’: drivers/net/vxlan.c:602: warning: ‘grc.offset’ may be used uninitialized in this function net/ipv4/fou.c: In function ‘gue_gro_receive’: net/ipv4/fou.c:262: warning: ‘grc.offset’ may be used uninitialized in this function While these are harmless for now: - skb_gro_remcsum_process() sets offset before changing delta, - skb_gro_remcsum_cleanup() checks if delta is non-zero before accessing offset, it's safer to let the initialization function initialize all members.

* ethernet/ixp4xx: prevent allmulti from clobbering promiscDerrick Pallas2015-02-201-1/+1
| | | | | | | | | | | | If both promisc and allmulti are set, promisc should trump allmulti and disable the MAC filter; otherwise, the interface is not really promisc. Previously, this code checked IFF_ALLMULTI prior to and without regard for IFF_PROMISC; if both were set, only multicast and direct unicast traffic would make it through the filter.

* openvswitch: Fix net exit.Pravin B Shelar2015-02-202-2/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Open vSwitch allows moving internal vport to different namespace while still connected to the bridge. But when namespace deleted OVS does not detach these vports, that results in dangling pointer to netdevice which causes kernel panic as follows. This issue is fixed by detaching all ovs ports from the deleted namespace at net-exit.

* net: phy: Fix verification of EEE support in phy_init_eeeGuenter Roeck2015-02-201-3/+20
| | | | | | | | | | | | | | | | | phy_init_eee uses phy_find_setting(phydev->speed, phydev->duplex) to find a valid entry in the settings array for the given speed and duplex value. For full duplex 1000baseT, this will return the first matching entry, which is the entry for 1000baseKX_Full. If the phy eee does not support 1000baseKX_Full, this entry will not match, causing phy_init_eee to fail for no good reason.

To further reduce the undetectability, detect card slot again in suspend method and defer the autosuspend if the slot is loaded.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver is used only on Exynos based boards with DTS support. After removal of board file support from max77686 and max77802 regulator drivers, the MFD driver can be converted to DTS-only version. This simplifies a little the code: 1. No dead (unused) entries in platform_data structure. 2. More code removed. 3. Regulator driver does not depend on allocated memory from MFD driver. 4. It makes also easier extending the regulator driver. Add to the max77686 MFD driver dependency on CONFIG_OF because without DTS the regulator drivers (max77686 and max77802) won't bind.

| * mfd: dln2: Add suspend/resume functionalityOctavian Purdila2015-01-221-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without suspend/resume functionality in the USB driver the USB core will disconnect and reconnect the DLN2 port and because the GPIO framework does not yet support removal of an in-use controller a suspend/resume operation will result in a crash. This patch provides suspend and resume functions for the DLN2 driver so that the above scenario is avoided, if the host controller does not drop VBUS during suspend, since in this case the device state is preserved. We chose not implemented reset_resume so that if the host controller does drop VBUS the resume path will go through above the disconnect/reconnect process since it is probably better to fix the GPIO framework disconnect issue then to save and restore the device state for every driver.
