[ Upstream commit d09220a887f70368afa79e850c95e74890c0a32d ]

With the CMA changes from Joonsoo Kim iamjoonsoo.kim@lge.com, it was noticed that n900 stopped booting. After investigating it turned out that n900 save_secure_ram_context does some whacky virtual to physical address translation for the SRAM data address.

As we now only have minimal parts of omap3 idle code copied to SRAM, running save_secure_ram_context() in SRAM is not needed. It only gets called on PM init. And it seems there's no need to ever call this from SRAM idle code.

So let's just keep save_secure_ram_context() in DDR, and pass it the physical address of the parameters. We can do everything else in omap-secure.c like we already do for other secure code.

And since we don't have any documentation, I still have no clue what the values for 0, 1 and 1 for the parameters might be. If somebody has figured it out, please do send a patch to add some comments.

[ Upstream commit cf87634c8b24e24bf379b8c6807c8b0fb5f23567 ]

There's been a reproducable USB OHCI/EHCI cpuidle related hang on omap4 for a while that happens after about 20 - 40 minutes on an idle system with some data feeding device being connected, like a USB GPS device or a cellular modem.

This issue happens in cpuidle states C2 and C3 and does not happen if cpuidle is limited to C1 state only. The symptoms are that the whole system hangs and never wakes up from idle, and if a watchdog is configured the system reboots after a while.

Turns out that OHCI/EHCI devices on omap4 are trying to use the GIC interrupt controller directly as a parent instead of the WUGEN. We need to pass the interrupts through WUGEN to GIC to provide the wakeup events for the processor.

Let's fix the issue by removing the gic interrupt-parent and use the default interrupt-parent wakeupgen instead. Note that omap5.dtsi had this already fixes earlier by commit 7136d457f365 ("ARM: omap: convert wakeupgen to stacked domains") but we somehow missed omap4 at that point.

The pin assignment for the wl127x interrupt was incorrect. I am not sure how this every worked. This also eliminates a conflict with the SMC911x ethernet driver and properly moves pinmuxes for the related gpio to omap3_pmx_wkup from omap3_pmx_core.

On the A80 the pins on port B can trigger interrupts, and those are assigned to the second interrupt bank. Having two pins assigned to the same interrupt bank/pin combination does not look healthy (instead more like a copy&paste bug from pins PA14-PA16), so fix the interrupt bank for pins PB14-PB16, which is actually 1.

I don't have any A80 board, so could not test this.

[ Upstream commit d30fc5126efb0c33b7adf5966d3051db2c3d7721 ]

Now outstanding_bytes is only increased when appending chunks into one packet and sending it at 1st time, while decreased when it is about to move into retransmit queue. It means outstanding_bytes value is already decreased for all chunks in retransmit queue.

However sctp_prsctp_prune_sent is a common function to check the chunks in both transmitted and retransmit queue, it decrease outstanding_bytes when moving a chunk into abandoned queue from either of them.

It could cause outstanding_bytes underflow, as it also decreases it's value for the chunks in retransmit queue.

This patch fixes it by only updating outstanding_bytes for transmitted queue when pruning queues for prsctp prio policy, the same fix is also needed in sctp_check_transmitted.

[ Upstream commit 969de0988b77e5a57aac2f7270191a3c50540c52 ]

Commit be7635e7287e ("arch, ftrace: for KASAN put hard/soft IRQ entries into separate sections") added a new linker section, SOFTIRQENTRY_TEXT, to the linker scripts for most architectures. It didn't add it to any of the linker scripts for the m68k architecture. This was not really a problem because it is only defined if either of CONFIG_FUNCTION_GRAPH_TRACER or CONFIG_KASAN are enabled - which can never be true for m68k.

However commit 229a71860547 ("irq: Make the irqentry text section unconditional") means that SOFTIRQENTRY_TEXT is now always defined. So on m68k we now end up with a separate ELF section for .softirqentry.text instead of it being part of the .text section. On some m68k targets in some configurations this can also cause a fatal link error:

LD vmlinux /usr/local/bin/../m68k-uclinux/bin/ld.real: section .softirqentry.text loaded at [0000000010de10c0,0000000010de12dd] overlaps section .rodata loaded at [0000000010de10c0,0000000010e0fd67]

To fix add in the missing SOFTIRQENTRY_TEXT section into the m68k linker scripts. I noticed that m68k is also missing the IRQENTRY_TEXT section, so this patch also adds an entry for that too.

According to LS1021A RM, the value of PAL can be set so that the start of the IP header in the receive data buffer is aligned to a 32-bit boundary. Normally, setting PAL = 2 provides minimal padding to ensure such alignment of the IP header.

However every incoming packet's 8-byte time stamp will be inserted into the packet data buffer as padding alignment bytes when hardware time stamping is enabled.

So we set the padding 8+2 here to avoid the flooded alignment faults:

When we do tunnel or beet mode, we pass saddr and daddr from the template to xfrm_state_find(), this is ok. On transport mode, we pass the addresses from the flowi, assuming that the IP addresses (and address family) don't change during transformation. This assumption is wrong in the IPv4 mapped IPv6 case, packet is IPv4 and template is IPv6.

Fix this by catching address family missmatches of the policy and the flow already before we do the lookup.

The capability check in nfnetlink_rcv() verifies that the caller has CAP_NET_ADMIN in the namespace that "owns" the netlink socket. However, xt_osf_fingers is shared by all net namespaces on the system. An unprivileged user can create user and net namespaces in which he holds CAP_NET_ADMIN to bypass the netlink_net_capable() check:

vpnns -- nfnl_osf -f /tmp/pf.os

vpnns -- nfnl_osf -f /tmp/pf.os -d

These non-root operations successfully modify the systemwide OS fingerprint list. Add new capable() checks so that they can't.

[ Upstream commit 732706afe1cc46ef48493b3d2b69c98f36314ae4 ]

On policies with a transport mode template, we pass the addresses from the flowi to xfrm_state_find(), assuming that the IP addresses (and address family) don't change during transformation.

Unfortunately our policy template validation is not strict enough. It is possible to configure policies with transport mode template where the address family of the template does not match the selectors address family. This lead to stack-out-of-bound reads because we compare arddesses of the wrong family. Fix this by refusing such a configuration, address family can not change on transport mode.

We use the assumption that, on transport mode, the first templates address family must match the address family of the policy selector. Subsequent transport mode templates must mach the address family of the previous template.

[ Upstream commit 6d60ce384d1d5ca32b595244db4077a419acc687 ]

If something calls ioremap() with an address not aligned to PAGE_SIZE, the returned address might be not aligned as well. This led to a probe registered on exactly the returned address, but the entire page was armed for mmiotracing.

On calling iounmap() the address passed to unregister_kmmio_probe() was PAGE_SIZE aligned by the caller leading to a complete freeze of the machine.

We should always page align addresses while (un)registerung mappings, because the mmiotracer works on top of pages, not mappings. We still keep track of the probes based on their real addresses and lengths though, because the mmiotrace still needs to know what are mapped memory regions.

Also move the call to mmiotrace_iounmap() prior page aligning the address, so that all probes are unregistered properly, otherwise the kernel ends up failing memory allocations randomly after disabling the mmiotracer.

This machine reports number of keyboard backlight led levels, instead of value of the last led level index. Therefore max_brightness properly needs to be subtracted by 1 to match led max_brightness API.
