2014-04-22i40e: Reset the VF upon conflicting VLAN configurationGreg Rose1-1/+25
If a host VMM administrator hoses his VF by assigning a port VLAN after it is already up and running with implicit permission to set local VLANs then we print a message warning the host administrator that the VF driver needs to be reloaded. In addition we need to knock the VF offline so that it does not continue to receive traffic not on the port VLAN assigned to it. So we reset the VF. The VF will cease operation and the administrator will be forced to unload and reload the VF driver to make it work again.

2014-04-21macvlan: Move broadcasts into a work queueHerbert Xu1-23/+93
Currently broadcasts are handled in network RX context, where the packets are sent through netif_rx. This means that the number of macvlans will be constrained by the capacity of netif_rx. For example, setting up 4096 macvlans practically causes all broadcast packets to be dropped as the default netif_rx queue size simply can't handle 4096 skbs being stuffed into it all at once. Fundamentally, we need to ensure that the amount of work handled in each netif_rx backlog run is constrained. As broadcasts are anything but constrained, it either needs to be limited per run or moved to process context. This patch picks the second option and moves all broadcast handling bar the trivial case of packets going to a single interface into a work queue. Obviously there also needs to be a limit on how many broadcast packets we postpone in this way. I've arbitrarily chosen tx_queue_len of the master device as the limit (act_mirred also happens to use this parameter in a similar way). In order to ensure we don't exceed the backlog queue we will use netif_rx_ni instead of netif_rx for broadcast packets.

For the iwlwifi bits, Emmanuel says: "I have new device IDs and a new firmware API. These are the trivial ones. The less trivial ones are Johannes's fix that delays the enablement of an interrupt coalescing hardware until after association - this fixes a few connection problems seen in the field. Eyal has a bunch of rate control fixes. I decided to add these for 3.15 because they fix some disconnection and packet loss scenarios which were reported by the field. I also have a fix for a memory leak that happens only with a very new NIC." Along with those... Amitkumar Karwar fixes a couple of problems relating to driver/firmware interactions in mwifiex. Christian Engelmayer avoids a couple of potential memory leaks in the new rsi driver. Eliad Peller provides a wl18xx mailbox alignment fix for problems when using new firmware. Frederic Danis adds a couple of missing debugging strings to the cw1200 driver. Geert Uytterhoeven adds a variable initialization inside of the rsi driver.

2014-04-19tg3: update rx_jumbo_pending ring param only when jumbo frames are enabledIvan Vecera1-1/+3
The patch fixes a problem with dropped jumbo frames after usage of 'ethtool -G ... rx'. Scenario: 1. ip link set eth0 up 2. ethtool -G eth0 rx N # <- This zeroes rx-jumbo 3. ip link set mtu 9000 dev eth0 The ethtool command set rx_jumbo_pending to zero so any received jumbo packets are dropped and you need to use 'ethtool -G eth0 rx-jumbo N' to workaround the issue. The patch changes the logic so rx_jumbo_pending value is changed only if jumbo frames are enabled (MTU > 1500).

2014-04-18drm: Split out drm_probe_helper.c from drm_crtc_helper.cDaniel Vetter3-371/+427
This is leftover stuff from my previous doc round which I kinda wanted to do but didn't yet due to rebase hell. The modeset helpers and the probing helpers a independent and e.g. i915 uses the probing stuff but has its own modeset infrastructure. It hence makes to split this up. While at it add a DOC: comment for the probing libraray. It would be rather neat to pull some of the DocBook documenting these two helpers into in-line DOC: comments. But unfortunately kerneldoc doesn't support markdown or something similar to make nice-looking documentation, so the current state is better.

2014-04-18drm/plane-helper: Don't fake-implement primary plane disablingDaniel Vetter1-28/+5
After thinking about this topic a bit more I've reached the conclusion that implementing this doesn't make sense: - The locking is all wrong: set_config(NULL) will also unlink encoders and connectors, but those links are protected with the mode_config mutex. In the ->disable_plane callback we only hold all modeset locks, but eventually we want to switch to just grabbing the per-crtc (and maybe per-plane) locks as needed, maybe based on ww_mutexes. Having a callback which absolutely needs all modeset locks is bad for this conversion. Note that the same isn't true for the provided ->update_plane since we've audited the crtc helpers to make sure that not encoder or connector links are changed. - There's no way to re-enable the plane with an ->update_plane: The connectors/encoder links are lost and so we can't re-enable the CRTC. Even without that issue the driver might have reassigned some shared resources (as opposed to e.g. DPMS off, where drivers are not allowed to do that to make sure the CRTC can be enabled again). - The semantics don't make much sense: Userspace asked to scan out black (or some other color if the driver supports a background color), not that the screen be disabled. - Implementing proper primary plane support (i.e. actually disabling the primary plane without disabling the CRTC) is really simple, at least if all the hw needs is flipping a bit. The big task is auditing all the interactions with other ioctls when the CRTC is on but there's no primary plane (e.g. pageflips). And some of that work still needs to be done.

2014-04-18drm/nouveau/bios: fix a bit shift error introduced by 457e77bSergei Antonov1-1/+1
Commit 457e77b26428ab4a24998eecfb99f27fa4195397 added two checks applied to a value received from nv_rd32(bios, 0x619f04). But after this new piece of code is executed, the addr local variable does not hold the same value it used to hold before the commit. Here is what is was assigned in the original code: (u64)(nv_rd32(bios, 0x619f04) & 0xffffff00) << 8 in the committed code it ends up with this value: (u64)(nv_rd32(bios, 0x619f04) >> 8) << 8 These expressions are obviously not equivalent. My Nvidia video card does not show anything on the display when I boot a kernel containing this commit. The patch fixes the code so that the new checks are still done, but the side effect of an incorrect addr value is gone.

A second commit removes an excess pad field in the parameter structure for the DRM_TEGRA_SUBMIT IOCTL. Archeaology on earlier versions of this file indicates that this was once there to pad an uneven number of u32 u32 fields, of which one was subsequently removed. Unfortunately nobody remembered to get rid of the padding when that happened.

2014-04-17ipmi: Turn off all activity on an idle ipmi interfaceCorey Minyard2-96/+174
The IPMI driver would wake up periodically looking for events and watchdog pretimeouts. If there is nothing waiting for these events, it's really kind of pointless to be checking for them. So modify the driver so the message handler can pass down if it needs the lower layer to be waiting for these. Modify the system interface lower layer to turn off all timer and thread activity if the upper layer doesn't need anything and it is not currently handling messages. And modify the message handler to not restart the timer if its timer is not needed. The timers and kthread will still be enabled if: - the SI interface is handling a message. - a user has enabled watching for events. - the IPMI watchdog timer is in use (since it uses pretimeouts). - the message handler is waiting on a remote response. - a user has registered to receive commands. This mostly affects interfaces without interrupts. Interfaces with interrupts already don't use CPU in the system interface when the interface is idle.

2014-04-17ipmi: Fix a race restarting the timerBodo Stroesser1-18/+28
With recent changes it is possible for the timer handler to detect an idle interface and not start the timer, but the thread to start an operation at the same time. The thread will not start the timer in that instance, resulting in the timer not running. Instead, move all timer operations under the lock and start the timer in the thread if it detect non-idle and the timer is not already running. Moving under locks allows the last timeout to be set in both the thread and the timer. 'Timer is not running' means that the timer is not pending and smi_timeout() is not running. So we need a flag to detect this correctly. Also fix a few other timeout bugs: setting the last timeout when the interrupt has to be disabled and the timer started, and setting the last timeout in check_start_timer_thread possibly racing with the timer Signed-off-by: Corey Minyard <cminyard@mvista.com> Signed-off-by: Bodo Stroesser <bstroesser@ts.fujitsu.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
