2016-09-30tg3: Avoid NULL pointer dereference in tg3_io_error_detected()Milton Miller1-5/+5
While the driver is probing the adapter, an error may occur before the netdev structure is allocated and attached to pci_dev. In this case, not only netdev isn't available, but the tg3 private structure is also not available as it is just math from the NULL pointer, so dereferences must be skipped. The following trace is seen when the error is triggered: [1.402247] Unable to handle kernel paging request for data at address 0x00001a99 [1.402410] Faulting instruction address: 0xc0000000007e33f8 [1.402450] Oops: Kernel access of bad area, sig: 11 [#1] [1.402481] SMP NR_CPUS=2048 NUMA PowerNV [1.402513] Modules linked in: [1.402545] CPU: 0 PID: 651 Comm: eehd Not tainted 4.4.0-36-generic #55-Ubuntu [1.402591] task: c000001fe4e42a20 ti: c000001fe4e88000 task.ti: c000001fe4e88000 [1.402742] NIP: c0000000007e33f8 LR: c0000000007e3164 CTR: c000000000595ea0 [1.402787] REGS: c000001fe4e8b790 TRAP: 0300 Not tainted (4.4.0-36-generic) [1.402832] MSR: 9000000100009033 <SF,HV,EE,ME,IR,DR,RI,LE> CR: 28000422 XER: 20000000 [1.403058] CFAR: c000000000008468 DAR: 0000000000001a99 DSISR: 42000000 SOFTE: 1 GPR00: c0000000007e3164 c000001fe4e8ba10 c0000000015c5e00 0000000000000000 GPR04: 0000000000000001 0000000000000000 0000000000000039 0000000000000299 GPR08: 0000000000000000 0000000000000001 c000001fe4e88000 0000000000000006 GPR12: 0000000000000000 c00000000fb40000 c0000000000e6558 c000003ca1bffd00 GPR16: 0000000000000000 0000000000000000 0000000000000000 0000000000000000 GPR20: 0000000000000000 0000000000000000 0000000000000000 c000000000d52768 GPR24: c000000000d52740 0000000000000100 c000003ca1b52000 0000000000000002 GPR28: 0000000000000900 0000000000000000 c00000000152a0c0 c000003ca1b52000 [1.404226] NIP [c0000000007e33f8] tg3_io_error_detected+0x308/0x340 [1.404265] LR [c0000000007e3164] tg3_io_error_detected+0x74/0x340 This patch avoids the NULL pointer dereference by moving the access after the netdev NULL pointer check on tg3_io_error_detected().

2016-09-27Revert "net: ethernet: bcmgenet: use phydev from struct net_device"Florian Fainelli3-31/+39
This reverts commit 62469c76007e ("net: ethernet: bcmgenet: use phydev from struct net_device") because it causes GENETv1/2/3 adapters to expose the following behavior after an ifconfig down/up sequence: PING fainelli-linux (10.112.156.244): 56 data bytes 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.352 ms 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.472 ms (DUP!) 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.496 ms (DUP!) 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.517 ms (DUP!) 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.536 ms (DUP!) 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.557 ms (DUP!) 64 bytes from 10.112.156.244: seq=1 ttl=61 time=752.448 ms (DUP!) This was previously fixed by commit 5dbebbb44a6a ("net: bcmgenet: Software reset EPHY after power on") but the commit we are reverting was essentially making this previous commit void, here is why. Without commit 62469c76007e we would have the following scenario after an ifconfig down then up sequence: - bcmgenet_open() calls bcmgenet_power_up() to make sure the PHY is initialized *before* we get to initialize the UniMAC, this is critical to ensure the PHY is in a correct state, priv->phydev is valid, this code executes fine - second time from bcmgenet_mii_probe(), through the normal phy_init_hw() call (which arguably could be optimized out) Everything is fine in that case. With commit 62469c76007e, we would have the following scenario to happen after an ifconfig down then up sequence: - bcmgenet_close() calls phy_disonnect() which makes dev->phydev become NULL - when bcmgenet_open() executes again and calls bcmgenet_mii_reset() from bcmgenet_power_up() to initialize the internal PHY, the NULL check becomes true, so we do not reset the PHY, yet we keep going on and initialize the UniMAC, causing MAC activity to occur - we call bcmgenet_mii_reset() from bcmgenet_mii_probe(), but this is too late, the PHY is botched, and causes the above bogus pings/packets transmission/reception to occur Reported-by: Jaedon Shin <jaedon.shin@gmail.com> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

2016-09-27net: fec: align IP header in hardwareEric Nelson1-1/+10
The FEC receive accelerator (RACC) supports shifting the data payload of received packets by 16-bits, which aligns the payload (IP header) on a 4-byte boundary, which is, if not required, at least strongly suggested by the Linux networking layer.

2016-09-22can: dev: fix deadlock reported after bus-offSergei Miroshnichenko1-10/+17
A timer was used to restart after the bus-off state, leading to a relatively large can_restart() executed in an interrupt context, which in turn sets up pinctrl. When this happens during system boot, there is a high probability of grabbing the pinctrl_list_mutex, which is locked already by the probe() of other device, making the kernel suspect a deadlock condition [1]. To resolve this issue, the restart_timer is replaced by a delayed work.

Other architectures pack the structs the same and don't need the compat wrapper. Use the same condition for drm_mode_fb_cmd2 as we use for drm_update_draw. Note that only the modifier will be packed differently between compat and non-compat versions. Reviewed-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Kristian H.

2016-09-19stmmac: fix PWRDWN into the PMT register for global unicast.Giuseppe CAVALLARO2-2/+2
MAC devices use the RWKPKTEN and MGKPKTEN bits of the PMT Control/Status register to generate power management events. So this patch is to properly set the RWKPKTEN [BIT(2)] inside the PMT register (needed in case of global unicast).

When CONFIG_PM is not set, we get a warning about an unused function: drivers/gpu/drm/exynos/exynos_drm_gsc.c:1219:12: error: 'gsc_clk_ctrl' defined but not used [-Werror=unused-function] static int gsc_clk_ctrl(struct gsc_context *ctx, bool enable) ^~~~~~~~~~~~ This removes the two #ifdef checks in this file and instead marks the functions as __maybe_unused, which is a more reliable way of doing the same, allowing better build coverage and avoiding the warning above.

2016-09-17bna: fix crash in bnad_get_strings()Ivan Vecera1-27/+23
Commit 6e7333d "net: add rx_nohandler stat counter" added the new entry rx_nohandler into struct rtnl_link_stats64. Unfortunately the bna driver foolishly depends on the structure. It uses part of it for ethtool statistics and it's not bad but the driver assumes its size is constant as it defines string for each existing entry. The problem occurs when the structure is extended because you need to modify bna driver as well. If not any attempt to retrieve ethtool statistics results in crash in bnad_get_strings(). The patch changes BNAD_ETHTOOL_STATS_NUM so it counts real number of strings in the array and also removes rtnl_link_stats64 entries that are not used in output and are always zero.

2016-09-17xen-netback: fix error handling on netback_probe()Filipe Manco1-16/+30
In case of error during netback_probe() (e.g. an entry missing on the xenstore) netback_remove() is called on the new device, which will set the device backend state to XenbusStateClosed by calling set_backend_state(). However, the backend state wasn't initialized by netback_probe() at this point, which will cause and invalid transaction and set_backend_state() to BUG(). Initialize the backend state at the beginning of netback_probe() to XenbusStateInitialising, and create two new valid state transitions on set_backend_state(), from XenbusStateInitialising to XenbusStateClosed, and from XenbusStateInitialising to XenbusStateInitWait.

Pull ARM fixes from Russell King: "Most of this update are fixes primarily discovered from testing on the older StrongARM 1110 and PXA systems, as a result of recent interest from several people in these platforms: - Locomo interrupt handling incorrectly stores the handler data in the chip's private data slot: when Locomo is combined with an interrupt controller who's chip uses the chip private data, this leads to an oops. - SA1111 was missing a call to clk_disable() to clean up after a failed probe. - SA1111 and PCMCIA suspend/resume was broken: The PCMCIA "ds" layer was using the legacy bus suspend/resume methods, which the core PM code is no longer calling as a result of device_pm_check_callbacks() introduced in commit aa8e54b559479 ("PM / sleep: Go direct_complete if driver has no callbacks"). SA1111 was broken due to changes to PCMCIA which makes PCMCIA suspend itself later than the SA1111 code expects, and resume before the SA1111 code has initialised access to the pcmcia sub-device. - the default SA1111 interrupt mask polarity got messed up when it was converted to use a dynamic interrupt base number for its interrupts. - fix platform_get_irq() error code propagation, which was causing problems on platforms where the interrupt may not be available at probe time in DT setups. - fix the lack of clock to PCMCIA code on PXA platforms, which was omitted in conversions of PXA to CCF. - fix an oops in the PXA PCMCIA code caused by a previous commit not realising that Lubbock is different from the rest of the PXA PCMCIA drivers. - ensure that SA1111 low-level PCMCIA drivers propagate their error codes to the main probe function, rather than the driver silently accepting a failure. - fix the sa11xx debugfs reporting of timing information, which always indicated zero due to the clock being a factor of 1000 out. - fix the polarity of the status change signal reported from the sockets.
