[ Upstream commit 21808437 ] MVPP2_TXQ_SCHED_TOKEN_CNTR_REG() expects the logical queue id but the current code is passing the global tx queue offset, so it ends up writing to unknown registers (between 0x8280 and 0x82fc, which seemed to be unused by the hardware). This fixes the issue by using the logical queue id instead. Fixes: 3f518509 ("ethernet: Add new driver for Marvell Armada 375 network unit") Signed-off-by:

[ Upstream commit a4270d67 ] If a network driver provides to napi_gro_frags() an skb with a page fragment of exactly 14 bytes, the call to gro_pull_from_frag0() will 'consume' the fragment by calling skb_frag_unref(skb, 0), and the page might be freed and reused. Reading eth->h_proto at the end of napi_frags_skb() might read mangled data, or crash under specific debugging features.

[ Upstream commit 31680ac2 ] IPv6 redirect is broken for VRF. __ip6_route_redirect walks the FIB entries looking for an exact match on ifindex. With VRF the flowi6_oif is updated by l3mdev_update_flow to the l3mdev index and the FLOWI_FLAG_SKIP_NH_OIF set in the flags to tell the lookup to skip the device match. For redirects the device match is requires so use that flag to know when the oif needs to be reset to the skb device index. Fixes: ca254490 ("net: Add VRF support to IPv6 stack") Signed-off-by:

[ Upstream commit 72f7cfab ] IPv6 does not consider if the socket is bound to a device when binding to an address. The result is that a socket can be bound to eth0 and then bound to the address of eth1. If the device is a VRF, the result is that a socket can only be bound to an address in the default VRF. Resolve by considering the device if sk_bound_dev_if is set. Signed-off-by:

[ Upstream commit b73484b2 ] When parsing an ethtool flow spec to build a flow_rule, the code checks if both the vlan etype and the vlan tci are specified by the user to add a FLOW_DISSECTOR_KEY_VLAN match. However, when the user only specified a vlan etype or a vlan tci, this check silently ignores these parameters. For example, the following rule : ethtool -N eth0 flow-type udp4 vlan 0x0010 action -1 loc 0 will result in no error being issued, but the equivalent rule will be created and passed to the NIC driver : ethtool -N eth0 flow-type udp4 action -1 loc 0 In the end, neither the NIC driver using the rule nor the end user have a way to know that these keys were dropped along the way, or that incorrect parameters were entered. This kind of check should be left to either the driver, or the ethtool flow spec layer. This commit makes so that ethtool parameters are forwarded as-is to the NIC driver. Since none of the users of ethtool_rx_flow_rule_create are using the VLAN dissector, I don't think this qualifies as a regression.

[ Upstream commit 33403121 ] Once in a while, with just the right timing, 802.3ad slaves will fail to properly initialize, winding up in a weird state, with a partner system mac address of 00:00:00:00:00:00. This started happening after a fix to properly track link_failure_count tracking, where an 802.3ad slave that reported itself as link up in the miimon code, but wasn't able to get a valid speed/duplex, started getting set to BOND_LINK_FAIL instead of BOND_LINK_DOWN. That was the proper thing to do for the general "my link went down" case, but has created a link initialization race that can put the interface in this odd state. The simple fix is to instead set the slave link to BOND_LINK_DOWN again, if the link has never been up (last_link_up == 0), so the link state doesn't bounce from BOND_LINK_DOWN to BOND_LINK_FAIL -- it hasn't failed in this case, it simply hasn't been up yet, and this prevents the unnecessary state change from DOWN to FAIL and getting stuck in an init failure w/o a partner mac.

[ Upstream commit d1ffa760 ] The quiesce function calls cio_cancel_halt_clear() and if we get an -EBUSY we go into a loop where we: - wait for any interrupts - flush all I/O in the workqueue - retry cio_cancel_halt_clear During the period where we are waiting for interrupts or flushing all I/O, the channel subsystem could have completed a halt/clear action and turned off the corresponding activity control bits in the subchannel status word. This means the next time we call cio_cancel_halt_clear(), we will again start by calling cancel subchannel and so we can be stuck between calling cancel and halt forever. Rather than calling cio_cancel_halt_clear() immediately after waiting, let's try to disable the subchannel. If we succeed in disabling the subchannel then we know nothing else can happen with the device. Suggested-by:

[ Upstream commit 85fb3526 ] The current code allows the TCON clock divider to have a range between 4 and 127 when feeding the DSI controller. The only display supported so far had a display clock rate that ended up using a divider of 4, but testing with other displays show that only 4 seems to be functional. This also aligns with what Allwinner is doing in their BSP, so let's just hardcode that we want a divider of 4 when using the DSI output. Reviewed-by:

[ Upstream commit da676c6a ] The current calculation for the video start delay in the current DSI driver is that it is the total vertical size, minus the front porch and sync length, plus 1. This equals to the active vertical size plus the back porch plus 1. That 1 is coming in the Allwinner BSP from an variable that is set to 1. However, if we look at the Allwinner BSP more closely, and especially in the "legacy" code for the display (in drivers/video/sunxi/legacy/), we can see that this variable is actually computed from the porches and the sync minus 10, clamped between 8 and 100. This fixes the start delay symptom we've seen on some panels (vblank timeouts with vertical white stripes at the bottom of the panel). Reviewed-by:

[ Upstream commit 4bc46da4 ] [Why] Seamless boot tries to reuse planes that were enabled for the first commit applied. In the case where Raven is booting with two monitors connected and the first commit contains two streams the screen corruption would occur because the second stream was trying to re-use a tg and plane that weren't previously enabled. The state on the first commit looks something like the following: TG0: enabled=1 TG1: enabled=0 TG2: enabled=0 TG3: enabled=0 New state: pipe=0, stream=0, plane=0, new_tg=0 New state: pipe=1, stream=1, plane=1, new_tg=1 New state: pipe=2, stream=NULL, plane=NULL, new_tg=NULL New state: pipe=3, stream=NULL, plane=NULL, new_tg=NULL Only one plane/tg is setup before we enter accelerated mode so we really want to disabling everything but that first plane. [How] Check if the stream is not NULL and if the tg is enabled before deciding whether to skip the plane disable. Also ensure we're also disabling on the current state's pipe_ctx so we don't overwrite the fields in the new pending state. Signed-off-by:

[ Upstream commit dcf1a988 ] [Why] AUX arbitration occurs between SW and FW components. When AUX acquire fails, it causes engine->ddc to be NULL, which leads to an exception when we try to release the AUX engine. [How] When AUX engine acquire fails, it should return from the function without trying to continue the operation. The upper level will determine if it wants to retry. i.e. dce_aux_transfer_with_retries will be used and retry. Signed-off-by:

[ Upstream commit 7d7b25d0 ] The SND_SOC_DAVINCI_MCASP driver can use either edma or sdma as a back-end, and it takes the presence of the respective dma engine drivers in the configuration as an indication to which ones should be built. However, this is flawed in multiple ways: - With CONFIG_TI_EDMA=m and CONFIG_SND_SOC_DAVINCI_MCASP=y, is enabled as =m, and we get a link error: sound/soc/ti/davinci-mcasp.o: In function `davinci_mcasp_probe': davinci-mcasp.c:(.text+0x930): undefined reference to `edma_pcm_platform_register' - When CONFIG_SND_SOC_DAVINCI_MCASP=m has already been selected by another driver, the same link error appears even if CONFIG_TI_EDMA is disabled There are possibly other issues here, but it seems that the only reasonable solution is to always build both SND_SOC_TI_EDMA_PCM and SND_SOC_TI_SDMA_PCM as a dependency here. Both are fairly small and do not have any other compile-time dependencies, so the cost is very small, and makes the configuration stage much more consistent.

[ Upstream commit 5442dcaa ] This fixes a bug for messages containing both zero length and unidirectional xfers. The function spi_map_msg will allocate dummy tx and/or rx buffers for use with unidirectional transfers when the hardware can only do a bidirectional transfer. That dummy buffer will be used in place of a NULL buffer even when the xfer length is 0. Then in the function __spi_map_msg, if he hardware can dma, the zero length xfer will have spi_map_buf called on the dummy buffer. Eventually, __sg_alloc_table is called and returns -EINVAL because nents == 0. This fix prevents the error by not using the dummy buffer when the xfer length is zero. Signed-off-by:
