2019-02-22net: thunderx: remove link change polling code and info from nicpfVadim Lomovtsev
Since link change polling routine was moved to nicvf side, we don't need anymore polling function at nicpf side along with link status info for all enabled Vfs as at VF side this info is already tracked. This commit is to remove unnecessary code & fields from nicpf structure. Signed-off-by: Vadim Lomovtsev <vlomovtsev@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-02-22net: thunderx: move link state polling function to VFVadim Lomovtsev
Move the link change polling task to VF side in order to prevent races between VF and PF while sending link change message(s). This commit is to implement link change request to be initiated by VF.

2019-02-22net: thunderx: add mutex to protect mailbox from concurrent calls for same VFVadim Lomovtsev
In some cases it could happen that nicvf_send_msg_to_pf() could be called concurrently for the same NIC VF, and thus re-writing mailbox contents and breaking messaging sequence with PF by re-writing NICVF data. This commit is to implement mutex for NICVF to protect mailbox registers and NICVF messaging control data from concurrent access.

2019-02-22net: thunderx: rework xcast message structure to make it fit into 64 bitVadim Lomovtsev
To communicate to PF each of ThunderX NIC VF uses mailbox which is pair of 64 bit registers available to both VFn and PF.

2019-02-22net: thunderx: add nicvf_send_msg_to_pf result check for set_rx_mode_taskVadim Lomovtsev
The rx_set_mode invokes number of messages to be send to PF for receive mode configuration. In case if there any issues we need to stop sending messages and release allocated memory.

2019-02-22net: thunderx: make CFG_DONE message to run through generic send-ack sequenceVadim Lomovtsev
At the end of NIC VF initialization VF sends CFG_DONE message to PF without using nicvf_msg_send_to_pf routine. This potentially could re-write data in mailbox. This commit is to implement common way of sending CFG_DONE message by the same way with other configuration messages by using nicvf_send_msg_to_pf() routine.

2019-02-22net: thunderx: replace global nicvf_rx_mode_wq work queue for all VFs to ↵Vadim Lomovtsev
private for each of them. Having one work queue for receive mode configuration ndo_set_rx_mode() call for all VFs results in making each of them wait till the set_rx_mode() call completes for another VF if any of close, set receive mode and change flags calls being already invoked. Potentially this could cause device state change before appropriate call of receive mode configuration completes, so the call itself became meaningless, corrupt data or break configuration sequence. We don't need any delays in NIC VF configuration sequence so having delayed work call with 0 delay has no sense. This commit is to implement one work queue for each NIC VF for set_rx_mode task and to let them work independently and replacing delayed_work with work_struct.

2019-02-22ipvlan: disallow userns cap_net_admin to change global mode/flagsDaniel Borkmann
When running Docker with userns isolation e.g. --userns-remap="default" and spawning up some containers with CAP_NET_ADMIN under this realm, I noticed that link changes on ipvlan slave device inside that container can affect all devices from this ipvlan group which are in other net namespaces where the container should have no permission to make changes to, such as the init netns, for example. This effectively allows to undo ipvlan private mode and switch globally to bridge mode where slaves can communicate directly without going through hostns, or it allows to switch between global operation mode (l2/l3/l3s) for everyone bound to the given ipvlan master device. libnetwork plugin here is creating an ipvlan master and ipvlan slave in hostns and a slave each that is moved into the container's netns upon creation event. * In hostns: # ip -d a [...] 8: cilium_host@bond0: <BROADCAST,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether 0c:c4:7a:e1:3d:cc brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535 ipvlan mode l3 bridge numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 inet 10.41.0.1/32 scope link cilium_host valid_lft forever preferred_lft forever [...] * Spawn container & change ipvlan mode setting inside of it: # docker run -dt --cap-add=NET_ADMIN --network cilium-net --name client -l app=test cilium/netperf 9fff485d69dcb5ce37c9e33ca20a11ccafc236d690105aadbfb77e4f4170879c # docker exec -ti client ip -d a [...] 10: cilium0@if4: <BROADCAST,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether 0c:c4:7a:e1:3d:cc brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535 ipvlan mode l3 bridge numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 inet 10.41.197.43/32 brd 10.41.197.43 scope global cilium0 valid_lft forever preferred_lft forever # docker exec -ti client ip link change link cilium0 name cilium0 type ipvlan mode l2 # docker exec -ti client ip -d a [...] 10: cilium0@if4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether 0c:c4:7a:e1:3d:cc brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535 ipvlan mode l2 bridge numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 inet 10.41.197.43/32 brd 10.41.197.43 scope global cilium0 valid_lft forever preferred_lft forever * In hostns (mode switched to l2): # ip -d a [...] 8: cilium_host@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether 0c:c4:7a:e1:3d:cc brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535 ipvlan mode l2 bridge numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 inet 10.41.0.1/32 scope link cilium_host valid_lft forever preferred_lft forever [...] Same l3 -> l2 switch would also happen by creating another slave inside the container's network namespace when specifying the existing cilium0 link to derive the actual (bond0) master: # docker exec -ti client ip link add link cilium0 name cilium1 type ipvlan mode l2 # docker exec -ti client ip -d a [...] 2: cilium1@if4: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether 0c:c4:7a:e1:3d:cc brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535 ipvlan mode l2 bridge numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 10: cilium0@if4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether 0c:c4:7a:e1:3d:cc brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535 ipvlan mode l2 bridge numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 inet 10.41.197.43/32 brd 10.41.197.43 scope global cilium0 valid_lft forever preferred_lft forever * In hostns: # ip -d a [...] 8: cilium_host@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether 0c:c4:7a:e1:3d:cc brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 65535 ipvlan mode l2 bridge numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535 inet 10.41.0.1/32 scope link cilium_host valid_lft forever preferred_lft forever [...] One way to mitigate it is to check CAP_NET_ADMIN permissions of the ipvlan master device's ns, and only then allow to change mode or flags for all devices bound to it.

2019-02-21bonding: fix PACKET_ORIGDEV regressionMichal Soltys
This patch fixes a subtle PACKET_ORIGDEV regression which was a side effect of fixes introduced by: 6a9e461f6fe4 bonding: pass link-local packets to bonding master also. ... to: b89f04c61efe bonding: deliver link-local packets with skb->dev set to link that packets arrived on While 6a9e461f6fe4 restored pre-b89f04c61efe presence of link-local packets on bonding masters (which is required e.g. by linux bridges participating in spanning tree or needed for lab-like setups created with group_fwd_mask) it also caused the originating device information to be lost due to cloning. Maciej Żenczykowski proposed another solution that doesn't require packet cloning and retains original device information - instead of returning RX_HANDLER_PASS for all link-local packets it's now limited only to packets from inactive slaves. At the same time, packets passed to bonding masters retain correct information about the originating device and PACKET_ORIGDEV can be used to determine it. This elegantly solves all issues so far: - link-local packets that were removed from bonding masters - LLDP daemons being forced to explicitly bind to slave interfaces - PACKET_ORIGDEV having no effect on bond interfaces Fixes: 6a9e461f6fe4 (bonding: pass link-local packets to bonding master also.)

2019-02-21i40e: fix XDP_REDIRECT/XDP xmit ring cleanup raceBjörn Töpel
When the driver clears the XDP xmit ring due to re-configuration or teardown, in-progress ndo_xdp_xmit must be taken into consideration. The ndo_xdp_xmit function is typically called from a NAPI context that the driver does not control. Therefore, we must be careful not to clear the XDP ring, while the call is on-going. This patch adds a synchronize_rcu() to wait for napi(s) (preempt-disable regions and softirqs), prior clearing the queue. Further, the __I40E_CONFIG_BUSY flag is checked in the ndo_xdp_xmit implementation to avoid touching the XDP xmit queue during re-configuration.

2019-02-21ixgbe: fix potential RX buffer starvation for AF_XDPMagnus Karlsson
When the RX rings are created they are also populated with buffers so that packets can be received. Usually these are kernel buffers, but for AF_XDP in zero-copy mode, these are user-space buffers and in this case the application might not have sent down any buffers to the driver at this point. And if no buffers are allocated at ring creation time, no packets can be received and no interrupts will be generated so the NAPI poll function that allocates buffers to the rings will never get executed. To rectify this, we kick the NAPI context of any queue with an attached AF_XDP zero-copy socket in two places in the code. Once after an XDP program has loaded and once after the umem is registered. This take care of both cases: XDP program gets loaded first then AF_XDP socket is created, and the reverse, AF_XDP socket is created first, then XDP program is loaded.

There was an attempt to guard against this in hubp1_cursor_set_position by checking the src_x_offset and src_y_offset and offseting the cursor hotspot within hubp1_cursor_set_position. However, the cursor position itself is still being programmed incorrectly as a large value. This manifests itself visually as the cursor disappearing or containing strange artifacts near the middle of the screen on raven. [How] Don't subtract the destination rect top left corner from the pos but add it to the hotspot instead. This happens before the pos gets passed into hubp1_cursor_set_position. This achieves the same result but avoids the subtraction wrap around. With this fix the original cursor programming logic can be used again.

2019-02-19gpu: drm: radeon: Set DPM_FLAG_NEVER_SKIP when enabling PM-runtimeRafael J. Wysocki
On HP ProBook 4540s, if PM-runtime is enabled in the radeon driver and the direct-complete optimization is used for the radeon device during system-wide suspend, the system doesn't resume. Preventing direct-complete from being used with the radeon device by setting the DPM_FLAG_NEVER_SKIP driver flag for it makes the problem go away, which indicates that direct-complete is not safe for the radeon driver in general and should not be used with it (at least for now). This fixes a regression introduced by commit c62ec4610c40 ("PM / core: Fix direct_complete handling for devices with no callbacks") which allowed direct-complete to be applied to devices without PM callbacks (again) which in turn unlocked direct-complete for radeon on HP ProBook 4540s.
