2019-02-20s390/jump_label: Use "jdd" constraint on gcc9Ilya Leoshkevich
[heiko.carstens@de.ibm.com]: ----- Laura Abbott reported that the kernel doesn't build anymore with gcc 9, due to the "X" constraint. Ilya provided the gcc 9 patch "S/390: Introduce jdd constraint" which introduces the new "jdd" constraint which fixes this. ----- The support for section anchors on S/390 introduced in gcc9 has changed the behavior of "X" constraint, which can now produce register references. Since existing constraints, in particular, "i", do not fit the intended use case on S/390, the new machine-specific "jdd" constraint was introduced. This patch makes jump labels use "jdd" constraint when building with gcc9.

2019-02-19net/mlx5e: Remove wrong and superfluous tc pedit header type checkVlad Buslov
With recent introduction of flow_rule infrastructure drivers no longer directly include action headers, so it is no longer possible to use constants defined in them. Instead, one of flow_rule patches substituted pedit action header constant with hardcoded value '2' in mlx5 set_pedit_val() function conditional which verifies that header type is in range of values allowed by pedit action. That conditional is now both wrong (hardcoded value is '2' but __PEDIT_HDR_TYPE_MAX is 6 in current version) and superfluous (pedit action already verifies that header type is in allowed range during init).

2019-02-19bpf: add skb->queue_mapping write access from tc clsactJesper Dangaard Brouer
The skb->queue_mapping already have read access, via __sk_buff->queue_mapping. This patch allow BPF tc qdisc clsact write access to the queue_mapping via tc_cls_act_is_valid_access. Also handle that the value NO_QUEUE_MAPPING is not allowed. It is already possible to change this via TC filter action skbedit tc-skbedit(8). Due to the lack of TC examples, lets show one: # tc qdisc add dev ixgbe1 clsact # tc filter add dev ixgbe1 ingress matchall action skbedit queue_mapping 5 # tc filter list dev ixgbe1 ingress The most common mistake is that XPS (Transmit Packet Steering) takes precedence over setting skb->queue_mapping. XPS is configured per DEVICE via /sys/class/net/DEVICE/queues/tx-*/xps_cpus via a CPU hex mask. To disable set mask=00. The purpose of changing skb->queue_mapping is to influence the selection of the net_device "txq" (struct netdev_queue), which influence selection of the qdisc "root_lock" (via txq->qdisc->q.lock) and txq->_xmit_lock. When using the MQ qdisc the txq->qdisc points to different qdiscs and associated locks, and HARD_TX_LOCK (txq->_xmit_lock), allowing for CPU scalability. Due to lack of TC examples, lets show howto attach clsact BPF programs: # tc qdisc add dev ixgbe2 clsact # tc filter add dev ixgbe2 egress bpf da obj XXX_kern.o sec tc_qmap2cpu # tc filter list dev ixgbe2 egress Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>

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.

2019-02-19MIPS: eBPF: Always return sign extended 32b valuesPaul Burton
The function prototype used to call JITed eBPF code (ie. the type of the struct bpf_prog bpf_func field) returns an unsigned int. The MIPS n64 ABI that MIPS64 kernels target defines that 32 bit integers should always be sign extended when passed in registers as either arguments or return values. This means that when returning any value which may not already be sign extended (ie. of type REG_64BIT or REG_32BIT_ZERO_EX) we need to perform that sign extension in order to comply with the n64 ABI. Without this we see strange looking test failures from test_bpf.ko, such as: test_bpf: #65 ALU64_MOV_X: dst = 4294967295 jited:1 ret -1 != -1 FAIL (1 times) Although the return value printed matches the expected value, this is only because printf is only examining the least significant 32 bits of the 64 bit register value we returned. The register holding the expected value is sign extended whilst the v0 register was set to a zero extended value by our JITed code, so when compared by a conditional branch instruction the values are not equal. We already handle this when the return value register is of type REG_32BIT_ZERO_EX, so simply extend this to also cover REG_64BIT.

2019-02-19bnxt_en: Return relevant error code when offload failsSriharsha Basavapatna
The driver returns -ENOSPC when tc_can_offload() check fails. Since that routine checks for flow parameters that are not supported by the driver, we should return the more appropriate -EOPNOTSUPP.

2019-02-19bnxt_en: Propagate trusted VF attribute to firmware.Michael Chan
Newer firmware understands the concept of a trusted VF, so propagate the trusted VF attribute set by the PF admin. to the firmware. Also, check the firmware trusted setting when considering the VF MAC address change and reporting the trusted setting to the user.

2019-02-19net/tls: Move protocol constants from cipher context to tls contextVakul Garg
Each tls context maintains two cipher contexts (one each for tx and rx directions). For each tls session, the constants such as protocol version, ciphersuite, iv size, associated data size etc are same for both the directions and need to be stored only once per tls context. Hence these are moved from 'struct cipher_context' to 'struct tls_prot_info' and stored only once in 'struct tls_context'. Signed-off-by: Vakul Garg <vakul.garg@nxp.com> Signed-off-by: David S.

2019-02-19ARM: dts: am335x-evm: Fix PHY mode for ethernetPeter Ujfalusi
The PHY must add both tx and rx delay and not only on the tx clock. The board uses AR8031_AL1A PHY where the rx delay is enabled by default, the tx dealy is disabled. The reason why rgmii-txid worked because the rx delay was not disabled by the driver so essentially we ended up with rgmii-id PHY mode.
