[ Upstream commit 73fbfc49 ] With commit 88ba95be ("backlight: pwm_bl: Compute brightness of LED linearly to human eye") the number of set bits (aka hweight()) in the PWM period is used in the heuristic to determine the number of brightness levels, when the brightness table isn't specified in the DT. The number of set bits doesn't provide a reliable clue about the length of the period, instead change the heuristic to: nlevels = period / fls(period) Also limit the maximum number of brightness levels to 4096 to avoid excessively large tables. With this the number of levels increases monotonically with the PWM period, until the maximum of 4096 levels is reached: period (ns) # levels 100 16 500 62 1000 111 5000 416 10000 769 50000 3333 100000 4096 Fixes: 88ba95be ("backlight: pwm_bl: Compute brightness of LED linearly to human eye") Signed-off-by:

[ Upstream commit 159dbaf5 ] The RELAX field of the OCOTP block is turning out as a zero on i.MX8MM. This messes up the subsequent re-load of the fuse shadow registers. After some discussion with people @ NXP its clear we have missed a trick here in Linux. The OCOTP fuse programming time has a physical minimum 'burn time' that is not related to the ipg_clk. We need to define the RELAX, STROBE_READ and STROBE_PROG fields in terms of desired timings to allow for the burn-in to safely complete. Right now only the RELAX field is calculated in terms of an absolute time and we are ending up with a value of zero. This patch inherits the u-boot timings for the OCOTP_TIMING calculation on the i.MX6 and i.MX8. Those timings are known to work and critically specify values such as STROBE_PROG as a minimum timing.

[ Upstream commit 0493c479 ] The i.MX6 and i.MX8 both have a bit-field spanning bits 27:22 called the WAIT field. The WAIT field according to the documentation for both parts "specifies time interval between auto read and write access in one time program. It is given in number of ipg_clk periods." This patch ensures that the relevant field is read and written back to the timing register. Fixes: 0642bac7 ("nvmem: imx-ocotp: add write support") Signed-off-by:

[ Upstream commit 40cb35d5 ] When we perform an inexact match on FIB nodes via fib6_locate_1(), longer prefixes will be preferred to shorter ones. However, it might happen that a node, with higher fn_bit value than some other, has no valid routing information. In this case, we'll pick that node, but it will be discarded by the check on RTN_RTINFO in fib6_locate(), and we might miss nodes with valid routing information but with lower fn_bit value. This is apparent when a routing exception is created for a default route: # ip -6 route list fc00:1::/64 dev veth_A-R1 proto kernel metric 256 pref medium fc00:2::/64 dev veth_A-R2 proto kernel metric 256 pref medium fc00:4::1 via fc00:2::2 dev veth_A-R2 metric 1024 pref medium fe80::/64 dev veth_A-R1 proto kernel metric 256 pref medium fe80::/64 dev veth_A-R2 proto kernel metric 256 pref medium default via fc00:1::2 dev veth_A-R1 metric 1024 pref medium # ip -6 route list cache fc00:4::1 via fc00:2::2 dev veth_A-R2 metric 1024 expires 593sec mtu 1500 pref medium fc00:3::1 via fc00:1::2 dev veth_A-R1 metric 1024 expires 593sec mtu 1500 pref medium # ip -6 route flush cache # node for default route is discarded Failed to send flush request: No such process # ip -6 route list cache fc00:3::1 via fc00:1::2 dev veth_A-R1 metric 1024 expires 586sec mtu 1500 pref medium Check right away if the node has a RTN_RTINFO flag, before replacing the 'prev' pointer, that indicates the longest matching prefix found so far.

With commit a647a025 ("s390/qeth: speed-up L3 IQD xmit"), the relevant xmit code in qeth has begun to use skb_cow_head(). So to avoid unnecessary skb head expansions, af_iucv must learn to 1) respect dev->needed_headroom when allocating skbs, and 2) drop the header reference before cloning the skb. While at it, also stop hard-coding the LL-header creation stage and just use the appropriate helper. Fixes: a647a025 ("s390/qeth: speed-up L3 IQD xmit") Signed-off-by:

[ Upstream commit 76e21533 ] Fixes an issue where TX Timestamps are not arriving on the error queue when UDP_SEGMENT CMSG type is combined with CMSG type SO_TIMESTAMPING. This can be illustrated with an updated updgso_bench_tx program which includes the '-T' option to test for this condition. It also introduces the '-P' option which will call poll() before reading the error queue. ./udpgso_bench_tx -4ucTPv -S 1472 -l2 -D 172.16.120.18 poll timeout udp tx: 0 MB/s 1 calls/s 1 msg/s The "poll timeout" message above indicates that TX timestamp never arrived. This patch preserves tx_flags for the first UDP GSO segment. Only the first segment is timestamped, even though in some cases there may be benefital in timestamping both the first and last segment. Factors in deciding on first segment timestamp only: - Timestamping both first and last segmented is not feasible. Hardware can only have one outstanding TS request at a time. - Timestamping last segment may under report network latency of the previous segments. Even though the doorbell is suppressed, the ring producer counter has been incremented. - Timestamping the first segment has the upside in that it reports timestamps from the application's view, e.g. RTT. - Timestamping the first segment has the downside that it may underreport tx host network latency. It appears that we have to pick one or the other. And possibly follow-up with a config flag to choose behavior. v2: Remove tests as noted by Willem de Bruijn <willemb@google.com> Moving tests from net to net-next v3: Update only relevant tx_flag bits as per Willem de Bruijn <willemb@google.com> v4: Update comments and commit message as per Willem de Bruijn <willemb@google.com> Fixes: ee80d1eb ("udp: add udp gso") Signed-off-by:

[ Upstream commit 177b8007 ] When GSO frame has to be corrupted netem uses skb_gso_segment() to produce the list of frames, and re-enqueues the segments one by one. The backlog length has to be adjusted to account for new frames. The current calculation is incorrect, leading to wrong backlog lengths in the parent qdisc (both bytes and packets), and incorrect packet backlog count in netem itself. Parent backlog goes negative, netem's packet backlog counts all non-first segments twice (thus remaining non-zero even after qdisc is emptied). Move the variables used to count the adjustment into local scope to make 100% sure they aren't used at any stage in backports. Fixes: 6071bd1a ("netem: Segment GSO packets on enqueue") Signed-off-by:

[ Upstream commit 942a8993 ] The call to sc_buffer_alloc currently returns NULL (no buffer) or a buffer descriptor. There is a third case when the port is down. Currently that returns NULL and this prevents the caller from properly handling the sc_buffer_alloc() failure. A verbs code link test after the call is racy so the indication needs to come from the state check inside the allocation routine to be valid. Fix by encoding the ECOMM failure like SDMA. IS_ERR_OR_NULL() tests are added at all call sites. For verbs send, this needs to treat any error by returning a completion without any MMIO copy.

However several devices can access the same reserved memory region and when building the list it is not safe to use a single iommu_resv_region object, whose container is the RMRR. This iommu_resv_region must be duplicated per device reserved region list. Let's remove the struct iommu_resv_region from the RMRR unit and allocate the iommu_resv_region directly in intel_iommu_get_resv_regions().

This is because the property should only be used when a board does not provide a proper AVB_LINK signal. However, the Ebisu board does provide this signal. As per 87c059e9 ("arm64: dts: renesas: salvator-x: Remove renesas, no-ether-link property") this fixes a bug: Steps to reproduce: - start AVB TX stream (Using aplay via MSE), - disconnect+reconnect the eth cable, - after a reconnection the eth connection goes iteratively up/down without user interaction, - this may heal after some seconds or even stay for minutes. As the documentation specifies, the "renesas,no-ether-link" option should be used when a board does not provide a proper AVB_LINK signal. There is no need for this option enabled on RCAR H3/M3 Salvator-X/XS and ULCB starter kits since the AVB_LINK is correctly handled by HW. Choosing to keep or remove the "renesas,no-ether-link" option will have impact on the code flow in the following ways: - keeping this option enabled may lead to unexpected behavior since the RX & TX are enabled/disabled directly from adjust_link function without any HW interrogation, - removing this option, the RX & TX will only be enabled/disabled after HW interrogation. The HW check is made through the LMON pin in PSR register which specifies AVB_LINK signal value (0 - at low level; 1 - at high level). In conclusion, the present change is also a safety improvement because it removes the "renesas,no-ether-link" option leading to a proper way of detecting the link state based on HW interrogation and not on software heuristic.

[ Upstream commit b926213d ] A request is zeroed in safexcel_ahash_exit_inv(). This request total size is EIP197_AHASH_REQ_SIZE while the memset zeroing it uses sizeof(struct ahash_request), which happens to be less than EIP197_AHASH_REQ_SIZE. This patch fixes it.
