2016-07-16et131x: Fix logical vs bitwise check in et131x_tx_timeout()Florian Fainelli1-1/+1

2016-07-16vlan: use a valid default mtu value for vlan over macsecPaolo Abeni3-6/+18
macsec can't cope with mtu frames which need vlan tag insertion, and vlan device set the default mtu equal to the underlying dev's one. By default vlan over macsec devices use invalid mtu, dropping all the large packets. This patch adds a netif helper to check if an upper vlan device needs mtu reduction. The helper is used during vlan devices initialization to set a valid default and during mtu updating to forbid invalid, too bit, mtu values. The helper currently only check if the lower dev is a macsec device, if we get more users, we need to update only the helper (possibly reserving an additional IFF bit).

2016-07-15mlxsw: spectrum: Prevent invalid ingress buffer mappingIdo Schimmel3-3/+19
Packets entering the switch are mapped to a Switch Priority (SP) according to their PCP value (untagged frames are mapped to SP 0). The packets are classified to a priority group (PG) buffer in the port's headroom according to their SP. The switch maintains another mapping (SP to IEEE priority), which is used to generate PFC frames for lossless PGs. This mapping is initialized to IEEE = SP % 8. Therefore, when mapping SP 'x' to PG 'y' we create a situation in which an IEEE priority is mapped to two different PGs: IEEE 'x' ---> SP 'x' ---> PG 'y' IEEE 'x' ---> SP 'x + 8' ---> PG '0' (default) Which is invalid, as a flow can use only one PG buffer. Fix this by mapping both SP 'x' and 'x + 8' to the same PG buffer.

2016-07-16xfs: fix type confusion in xfs_ioc_swapextJann Horn1-0/+6
Without this check, the following XFS_I invocations would return bad pointers when used on non-XFS inodes (perhaps pointers into preceding allocator chunks). This could be used by an attacker to trick xfs_swap_extents into performing locking operations on attacker-chosen structures in kernel memory, potentially leading to code execution in the kernel. (I have not investigated how likely this is to be usable for an attack in practice.)

Alex fixes issues found in i40e_rx_checksum() which was broken, where the checksum was being returned valid when it was not. Kiran fixes a bug which was found when we abruptly remove a cable which caused a panic. Set the VSI broadcast promiscuous mode during VSI add sequence and prevents adding MAC filter if specified MAC address is broadcast. Paolo Abeni fixes a bug by returning the actual work done, capped to weight - 1, since the core doesn't allow to return the full budget when the driver modifies the NAPI status. Guilherme Piccoli fixes an issue where the q_vector initialization routine sets the affinity _mask of a q_vector based on v_idx value. This means a loop iterates on v_idx, which is an incremental value, and the cpumask is created based on this value. This is a problem in systems with multiple logical CPUs per core (like in SMT scenarios). Changed the way q_vector's affinity_mask is created to resolve the issue. ==================== Signed-off-by: David S. Miller <[email protected]>

2016-07-15tcp: enable per-socket rate limiting of all 'challenge acks'Jason Baron1-17/+22
The per-socket rate limit for 'challenge acks' was introduced in the context of limiting ack loops: commit f2b2c582e824 ("tcp: mitigate ACK loops for connections as tcp_sock") And I think it can be extended to rate limit all 'challenge acks' on a per-socket basis. Since we have the global tcp_challenge_ack_limit, this patch allows for tcp_challenge_ack_limit to be set to a large value and effectively rely on the per-socket limit, or set tcp_challenge_ack_limit to a lower value and still prevents a single connections from consuming the entire challenge ack quota. It further moves in the direction of eliminating the global limit at some point, as Eric Dumazet has suggested.

2016-07-16media: fix airspy usb probe error pathJames Patrick-Evans1-2/+1
Fix a memory leak on probe error of the airspy usb device driver. The problem is triggered when more than 64 usb devices register with v4l2 of type VFL_TYPE_SDR or VFL_TYPE_SUBDEV. The memory leak is caused by the probe function of the airspy driver mishandeling errors and not freeing the corresponding control structures when an error occours registering the device to v4l2 core. A badusb device can emulate 64 of these devices, and then through continual emulated connect/disconnect of the 65th device, cause the kernel to run out of RAM and crash the kernel, thus causing a local DOS vulnerability.

Now that we include the processor type in the pci_id_table structure we can skip the wrappers and just have the sbridge_get_all_devices() check the type to decide whether to allow duplicate devices and controllers to have registers spread across buses.

2016-07-15drm/i915/kbl: Add WaEnableGapsTsvCreditFixMika Kuoppala1-0/+5
We need this crucial workaround from skl also to all kbl revisions. Lack of it was causing system hangs on skl enabling so this is a must have. v2: Don't add revid checks to gen9 init workarounds (Arun) References: HSD#2126660 Cc: Arun Siluvery <[email protected]> Signed-off-by: Mika Kuoppala <[email protected]> Reviewed-by: Matthew Auld <[email protected]> Link: http://patchwork.freedesktop.org/patch/msgid/[email protected] (cherry picked from commit e587f6cb0af140f3c0ea794d8616eb9a29969983) Signed-off-by: Mika Kuoppala <[email protected]>
2016-07-15drm/i915: Mimic skl with WaForceEnableNonCoherentMika Kuoppala1-16/+21
Past evidence with system hangs and hsds tie WaForceEnableNonCoherent and WaDisableHDCInvalidation to WaForceContextSaveRestoreNonCoherent. Documentation states that WaForceContextSaveRestoreNonCoherent would not be needed on skl past E0 but evidence proved otherwise. See commit <510650e8b2ab> ("drm/i915/skl: Fix spurious gpu hang with gt3/gt4 revs"). In this scope consider kbl to be skl with a bigger revision than E0 so play it safe and bind these two workarounds to the WaForceContextSaveRestoreNonCoherent, and apply to all gen9. v2: fix comment (Matthew) References: HSD#2134449, HSD#2131413 Signed-off-by: Mika Kuoppala <[email protected]> Reviewed-by: Matthew Auld <[email protected]> Link: http://patchwork.freedesktop.org/patch/msgid/[email protected] (cherry picked from commit bbaefe72a00c93c6ec12e029019681e3f7d7de7a) Signed-off-by: Mika Kuoppala <[email protected]>

We need this for kbl a0 boards. Note that this should be also for bxt A0 but we omit that on purpose as bxt A0's are out of fashion already.
