getsockopt(TCP_ZEROCOPY_RECEIVE) has a bug where we read a user-provided "len" field of type signed int, and then compare the value to the result of an "offsetofend" operation, which is unsigned. Negative values provided by the user will be promoted to large positive numbers; thus checking that len < offsetofend() will return false when the intention was that it return true. Note that while len is originally checked for negative values earlier on in do_tcp_getsockopt(), subsequent calls to get_user() re-read the value from userspace which may have changed in the meantime. Therefore, re-add the check for negative values after the call to get_user in the handler code for TCP_ZEROCOPY_RECEIVE. Fixes: c8856c05 ("tcp-zerocopy: Return inq along with tcp receive zerocopy.")

When accessing the timecounter register on an i.MX8MQ the kernel hangs. This is only the case when the interface is down. This can be reproduced by reading with 'phc_ctrl eth0 get'. Like described in the change in 91c0d987 the igp clock is disabled when the interface is down and leads to a system hang. So we check if the ptp clock status before reading the timecounter register.

When CONFIG_PM_SLEEP is disabled, the compiler warns about unused functions: drivers/net/phy/phy_device.c:273:12: error: unused function 'mdio_bus_phy_suspend' [-Werror,-Wunused-function] static int mdio_bus_phy_suspend(struct device *dev) drivers/net/phy/phy_device.c:293:12: error: unused function 'mdio_bus_phy_resume' [-Werror,-Wunused-function] static int mdio_bus_phy_resume(struct device *dev) The logic is intentional, so just mark these two as __maybe_unused and remove the incorrect #ifdef.

During suspend/resume stress test, we found descriptor write back by DMA could exhibit unusual behavior, e.g.: 003 [0xc4310030]: 0x0 0x40 0x0 0xb5010040 We can see that desc3 write back is 0xb5010040, it is still ownd by DMA, so application would not recycle this buffer. It will trigger fatal bus error when DMA try to use this descriptor again. To fix this issue, we should re-init all rx buffers when mac resume back. Signed-off-by:

Driver uses dma_alloc_coherent to allocate dma memory for descriptors, dma_alloc_coherent will return both the virtual address and physical address. AFAIK, virt_to_phys could not convert virtual address to physical address, for which memory is allocated by dma_alloc_coherent. dwmac4_display_ring() function is broken for various descriptor, it only support normal descriptor(struct dma_desc) now, this patch also extends to support all descriptor types.

stmmac_xmit() call stmmac_tx_timer_arm() at the end to modify tx timer to do the transmission cleanup work. Imagine such a situation, stmmac enters suspend immediately after tx timer modified, it's expire callback stmmac_tx_clean() would not be invoked. This could affect BQL, since netdev_tx_sent_queue() has been called, but netdev_tx_completed_queue() have not been involved, as a result, dql_avail(&dev_queue->dql) finally always return a negative value. __dev_queue_xmit->__dev_xmit_skb->qdisc_run->__qdisc_run->qdisc_restart->dequeue_skb: if ((q->flags & TCQ_F_ONETXQUEUE) && netif_xmit_frozen_or_stopped(txq)) // __QUEUE_STATE_STACK_XOFF is set Net core will stop transmitting any more.

Following a similar reinstate for the KSZ9031. Older kernels would use the genphy_soft_reset if the PHY did not implement a .soft_reset. Bluntly removing that default may expose a lot of situations where various PHYs/board implementations won't recover on various changes. Like with this implementation during a 4.9.x to 5.4.x LTS transition. I think it's a good thing to remove unwanted soft resets but wonder if it did open a can of worms? Atleast this fixes one iMX6 FEC/RMII/8081 combo. Fixes: 6e2d85ec ("net: phy: Stop with excessive soft reset") Signed-off-by:

Currently, the psample netlink skb is allocated with a size that does not account for the nested 'PSAMPLE_ATTR_TUNNEL' attribute and the padding required for the 64-bit attribute 'PSAMPLE_TUNNEL_KEY_ATTR_ID'. This can result in failure to add attributes to the netlink skb due to insufficient tail room. The following error message is printed to the kernel log: "Could not create psample log message". Fix this by adjusting the allocation size to take into account the nested attribute and the padding.

sja1105_unpack() takes a "const void *buf" as its first parameter, so there is no need to cast away the "const" of the "buf" variable before calling it. Drop the cast, as it prevents the compiler performing some checks. Signed-off-by:

The panel is able to work when dsi clock is non-continuous, thus the system power consumption can be reduced using such feature. Add MIPI_DSI_CLOCK_NON_CONTINUOUS to panel's mode_flags. Also the flag actually becomes necessary after commit c6d94e37 ("drm/bridge/synopsys: dsi: add support for non-continuous HS clock") and without it the panel only emits stripes instead of output.
