[ Upstream commit fe4dd423 ] A CA is supposed to ignore FECN bits in multicast, ACK, and CNP packets. This patch corrects the behavior of the HFI1 driver in this regard by ignoring FECNs in those packet types. While fixing the above behavior, fix the extraction of the FECN and BECN bits from the packet headers for both 9B and 16B packets. Furthermore, this patch corrects the driver's response to a FECN in RDMA READ RESPONSE packets. Instead of sending an "empty" ACK, the driver now sends a CNP packet. While editing that code path, add the missing trace for CNP packets. Fixes: 88733e3b ("IB/hfi1: Add 16B UD support") Fixes: f59fb9e0 ("IB/hfi1: Fix handling of FECN marked multicast packet") Reviewed-by:

[ Upstream commit c54c7374 ] Jerry Zuo pointed out a rather obscure hotplugging issue that it seems I accidentally introduced into DRM two years ago. Pretend we have a topology like this: |- DP-1: mst_primary |- DP-4: active display |- DP-5: disconnected |- DP-6: active hub |- DP-7: active display |- DP-8: disconnected |- DP-9: disconnected If we unplug DP-6, the topology starting at DP-7 will be destroyed but it's payloads will live on in DP-1's VCPI allocations and thus require removal. However, this removal currently fails because drm_dp_update_payload_part1() will (rightly so) try to validate the port before accessing it, fail then abort. If we keep going, eventually we run the MST hub out of bandwidth and all new allocations will start to fail (or in my case; all new displays just start flickering a ton). We could just teach drm_dp_update_payload_part1() not to drop the port ref in this case, but then we also need to teach drm_dp_destroy_payload_step1() to do the same thing, then hope no one ever adds anything to the that requires a validated port reference in drm_dp_destroy_connector_work(). Kind of sketchy. So let's go with a more clever solution: any port that drm_dp_destroy_connector_work() interacts with is guaranteed to still exist in memory until we say so. While said port might not be valid we don't really care: that's the whole reason we're destroying it in the first place! So, teach drm_dp_get_validated_port_ref() to use the all mighty current_work() function to avoid attempting to validate ports from the context of mgr->destroy_connector_work. I can't see any situation where this wouldn't be safe, and this avoids having to play whack-a-mole in the future of trying to work around port validation. Signed-off-by:

[ Upstream commit aba36930 ] In ip packet generation, pagedlen is initialized for each skb at the start of the loop in __ip(6)_append_data, before label alloc_new_skb. Depending on compiler options, code can be generated that jumps to this label, triggering use of an an uninitialized variable. In practice, at -O2, the generated code moves the initialization below the label. But the code should not rely on that for correctness.

[ Upstream commit 576ce407 ] gcc notices that without either the ac97 bus or the pdata, we never initialize the regmap pointer, which leads to an uninitialized variable access: sound/soc/codecs/wm9712.c: In function 'wm9712_soc_probe': sound/soc/codecs/wm9712.c:666:2: error: 'regmap' may be used uninitialized in this function [-Werror=maybe-uninitialized] Since that configuration is invalid, it's better to return an error here. I tried to avoid adding complexity to the conditions, and turned the #ifdef into a regular if(IS_ENABLED()) check for readability. This in turn requires moving some header file declarations out of an #ifdef. The same code is used in three drivers, all of which I'm changing the same way.

[ Upstream commit 0fe64023 ] An MC-aware mode was introduced in commit 7b819530 ("mlxsw: spectrum: Configure MC-aware mode on mlxsw ports"). In MC-aware mode, BUM traffic gets a special treatment by being assigned to a separate set of traffic classes 8..15. Pairs of TCs 0 and 8, 1 and 9, etc., are then configured to strictly prioritize the lower-numbered ones. The intention is to prevent BUM traffic from flooding the switch and push out all UC traffic, which would otherwise happen, and instead give UC traffic precedence. However strictly prioritizing UC traffic has the effect that UC overload pushes out all BUM traffic, such as legitimate ARP queries. These packets are kept in queues for a while, but under sustained UC overload, their lifetime eventually expires and these packets are dropped. That is detrimental to network performance as well. Therefore configure the MC TCs (8..15) with minimum shaper of 200Mbps (a minimum permitted value) to allow a trickle of necessary control traffic to get through.

[ Upstream commit a3241a91 ] There is a compatibility issue between RTL8211E implemented in Developerbox and netsec ethernet controller IP. Our MDIO controller stops MDC clock right after the write access, but RTL8211E expects MDC clock must be kept toggling for several clock cycle with MDIO high before entering the IDLE state. Without keeping clock after write access, write access is not correctly handled and register is not updated. To meet this requirement, netsec driver needs to issue dummy read(e.g. read PHYID1(offset 0x2) register) right after write access, to keep MDC clock. We think this compatibility issue is a problem specific to our MDIO controller and RTL8211E. Fixes: 533dd11a ("net: socionext: Add Synquacer NetSec driver") Signed-off-by:

[ Upstream commit 988f3f16 ] We have seen the following race scenario: 1) named_distribute() builds a "bulk" message, containing a PUBLISH item for a certain publication. This is based on the contents of the binding tables's 'cluster_scope' list. 2) tipc_named_withdraw() removes the same publication from the list, bulds a WITHDRAW message and distributes it to all cluster nodes. 3) tipc_named_node_up(), which was calling named_distribute(), sends out the bulk message built under 1) 4) The WITHDRAW message arrives at the just detected node, finds no corresponding publication, and is dropped. 5) The PUBLISH item arrives at the same node, is added to its binding table, and remains there forever. This arrival disordering was earlier taken care of by the backlog queue, originally added for a different purpose, which was removed in the commit referred to below, but we now need a different solution. In this commit, we replace the rcu lock protecting the 'cluster_scope' list with a regular RW lock which comprises even the sending of the bulk message. This both guarantees both the list integrity and the message sending order. We will later add a commit which cleans up this code further. Note that this commit needs recently added commit d3092b2e ("tipc: fix unsafe rcu locking when accessing publication list") to apply cleanly.

On e-series devices, the first three of the last four bits are reserved. The last bit defines the output selection of the RGOUT0 pin, otherwise known as RTSI_Sub_Selection.

Similar udc->phy_mode is initially 0 (as udc_controller was allocated with kzalloc in fsl_udc_probe()) so reset it to 0 as well so that this function is side-effect free on failure. Not clear if this is necessary or sensible as fsl_udc_release() probably can not be called if fsl_udc_probe() failed - but it should not hurt. Signed-off-by:

[ Upstream commit 3def4031 ] Like the omap back-end, we get a link error with CONFIG_EXTCON=m when building the qcom back-end into the kernel: drivers/usb/dwc3/dwc3-qcom.o: In function `dwc3_qcom_probe': dwc3-qcom.c:(.text+0x13dc): undefined reference to `extcon_get_edev_by_phandle' dwc3-qcom.c:(.text+0x1b18): undefined reference to `devm_extcon_register_notifier' dwc3-qcom.c:(.text+0x1b9c): undefined reference to `extcon_get_state' Do the same thing as OMAP and add an explicit dependency on EXTCON.

[ Upstream commit 94967b55 ] On a DT based system, we use the of_node full name to name the corresponding irq domain. We expect that name to be unique, so so that domains with the same base name won't clash (this happens on multi-node topologies, for example). Since a7e4cfb0 ("of/fdt: only store the device node basename in full_name"), of_node_full_name() lies and only returns the basename. This breaks the above requirement, and we end-up with only a subset of the domains in /sys/kernel/debug/irq/domains. Let's reinstate the feature by using the fancy new %pOF format specifier, which happens to do the right thing.

[ Upstream commit eb501309 ] Since Virtual Lanes BCT credits and MTU are set through separate MADs, we have to ensure both are valid, and data VLs are ready for transmission before we allow port transition to Armed state.
