The TRM has marked dra7 SmartReflex as reserved and we should not touch those registers as pointed out by Nishanth Menon <nm@ti.com>. We do still want to idle the related interconnect target modules on init though. Let's do this by only configuring the generic interconnect target modules and not add the child SmartReflex devices.

On omap4 we are missing dts nodes for several interconnect target modules that we are idling on init. This currently works with the legacy platform data still around. To fix this, let's add the interconnect target modules so we can idle the unused interconnect target module on init. Also note that adding the interconnect target module node does not necessarily mean that there is a driver available for the child IP block, or that the child IP block is even functional. In the SGX case, the PowerVR driver is closed source. And McASP on omap4 has at least the TX path disabled and is not supported by the davinci-mcasp driver. For AESS there is old Android 3.4 kernel driver available. For smarflex, we are still probing with platform data and the driver needs more work before we can add the device ip child nodes. And finally, we're not yet using the interconnet ranges. I will be posting separate patches for those later on.

With the recently introduced omap clkctrl module binding, we can start moving omap hwmod data to device tree and drivers from arch/arm/mach-omap2. To start doing this, let's introduce a device tree binding for TI sysc interconnect target module hardware. The sysc manages module clocks, idlemodes and interconnect level resets. Each interconnect target module can have one or more child devices connected to it. TI sysc interconnect target module hardware is independent of the interconnect. It is used at least with TI L3 interconnect (Arteris NoC) and TI L4 interconnect (Sonics s3220). The sysc is mostly used for interaction between module and PRCM. It participates in the OCP Disconnect Protocol but other than that is mostly indepenent of the interconnect. As all the features may not be supported for a given sysc module, we need to use device tree configuration for the revision of the interconnect target module. Note that the interconnect target module control registers are always sprinked at varying locations in the unused address space of the first child device IP block. To avoid device tree reg conflicts, the sysc device provides ranges for it's children. For a non-intrusive transition from static hwmod data to using device tree defined TI interconnect target module binding, we can keep things working with static hwmod data if device tree property "ti,hwmods" is specified for the the interconnect target module. Note that additional properties for sysc capabilities will be added later on. For now, we can already use this binding for interconnect target modules that do not have any child device drivers available. This allows us to idle the unused interconnect target modules during init without the need for legacy hwmod platform data for doing it.

Note that this will only show up as a bug with "doesn't have mpu register target base" boot errors when the legacy platform data is removed. In order to add these, we need to move omap4_pmx_wkup to be a child of omap4_padconf_wkup. On omap4 there are separate modules for control module and control module pads. For control module core, we have this already configured except for the missing ti,hwmods and reg entries. Cc: Mark Rutland <mark.rutland@arm.com> Acked-by:

On omap4430, the PMU is not configure unlike on omap4460 because of the missing handling. The missing pmu node with the missing ti,hwmods entry will cause boot time errors when the legacy platform data is removed as the SoC interconnect code needs it. Note that this will only show up as a bug with "doesn't have mpu register target base" boot errors when the legacy platform data is removed. Let's fix the issue by configuring PMU but without the interrupts. Then when cross trigger interface (CTI) is supported, we can add interrupts also for omap4430.

Commit 5620a0d1 ("firmware: delete in-kernel firmware") removed the entire firmware directory. Unfortunately it thereby also removed the support for built-in firmware. This restores the ability to build firmware directly into the kernel by pruning the original Makefile to the necessary minimum.

The driver doesn't support events from address families other than IPv4 and IPv6, so ignore them. Otherwise, we risk queueing a work item before it's initialized. This can happen in case a VRF is configured when MROUTE_MULTIPLE_TABLES is enabled, as the VRF driver will try to add an l3mdev rule for the IPMR family.

sctp_diag would not actually dump out sk/asoc if inet_sctp_diag_fill returns err, in which case it shouldn't mark sk dumped by setting cb->args[3] as 1 in sctp_sock_dump(). Otherwise, it could cause some asocs to have no parent's sk dumped in 'ss --sctp'. So this patch is to not set cb->args[3] when inet_sctp_diag_fill() returns err in sctp_sock_dump().

Commit 86fdb344 ("sctp: ensure ep is not destroyed before doing the dump") tried to fix an use-after-free issue by checking !sctp_sk(sk)->ep with holding sock and sock lock. But Paolo noticed that endpoint could be destroyed in sctp_rcv without sock lock protection. It means the use-after-free issue still could be triggered when sctp_rcv put and destroy ep after sctp_sock_dump checks !ep, although it's pretty hard to reproduce. I could reproduce it by mdelay in sctp_rcv while msleep in sctp_close and sctp_sock_dump long time. This patch is to add another param cb_done to sctp_for_each_transport and dump ep->assocs with holding tsp after jumping out of transport's traversal in it to avoid this issue. It can also improve sctp diag dump to make it run faster, as no need to save sk into cb->args[5] and keep calling sctp_for_each_transport any more. This patch is also to use int * instead of int for the pos argument in sctp_for_each_transport, which could make postion increment only in sctp_for_each_transport and no need to keep changing cb->args[2] in sctp_sock_filter and sctp_sock_dump any more.

liujian reported a problem in TCP_USER_TIMEOUT processing with a patch in tcp_probe_timer() : https://www.spinics.net/lists/netdev/msg454496.html After investigations, the root cause of the problem is that we update skb->skb_mstamp of skbs in write queue, even if the attempt to send a clone or copy of it failed. One reason being a routing problem. This patch prevents this, solving liujian issue. It also removes a potential RTT miscalculation, since __tcp_retransmit_skb() is not OR-ing TCP_SKB_CB(skb)->sacked with TCPCB_EVER_RETRANS if a failure happens, but skb->skb_mstamp has been changed. A future ACK would then lead to a very small RTT sample and min_rtt would then be lowered to this too small value.

rt_iif is only set to the actual egress device for the output path. The recent change to consider the l3slave flag when returning IP_PKTINFO works for local traffic (the correct device index is returned), but it broke the more typical use case of packets received from a remote host always returning the VRF index rather than the original ingress device. Update the fixup to consider l3slave and rt_iif actually getting set. Fixes: 1dfa7639 ("net: ipv4: add check for l3slave for index returned in IP_PKTINFO") Signed-off-by:

If the network interface is kept running during suspend, the net core may call net_device_ops.ndo_start_xmit() while the Ethernet device is still suspended, which may lead to a system crash. E.g. on sh73a0/kzm9g and r8a73a4/ape6evm, the external Ethernet chip is driven by a PM controlled clock. If the Ethernet registers are accessed while the clock is not running, the system will crash with an imprecise external abort. As this is a race condition with a small time window, it is not so easy to trigger at will. Using pm_test may increase your chances: # echo 0 > /sys/module/printk/parameters/console_suspend # echo platform > /sys/power/pm_test # echo mem > /sys/power/state To fix this, make sure the network interface is quietened during suspend.

We can enter a deadlock situation because there is no sufficient protection when ndo_get_stats64() runs in process context to guard against RX or TX NAPI contexts running in softirq, this can lead to the following lockdep splat and actual deadlock was experienced as well with an iperf session in the background and a while loop doing ifconfig + ethtool.

When building an allmodconfig kernel with gcc-4.6, we get a rather odd warning: drivers/net/vrf.c: In function ‘vrf_ip6_input_dst’: drivers/net/vrf.c:964:3: error: initialized field with side-effects overwritten [-Werror] drivers/net/vrf.c:964:3: error: (near initialization for ‘fl6’) [-Werror] I have no idea what this warning is even trying to say, but it does seem like a false positive. Reordering the initialization in to match the structure definition gets rid of the warning, and might also avoid whatever gcc thinks is wrong here.
