#1418736 — [PATCH 4.2.y-ckt 170/206] taskstats: fix nl parsing in accounting/getdelays.c

4.2.8-ckt12 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Nicolas Dichtel <nicolas.dichtel@6wind.com>

commit 570d8e9398011a63590c281a36cdce311196608e upstream.

The type TASKSTATS_TYPE_NULL should always be ignored.

When jumping to the next attribute, only the length of the current
attribute should be added, not the length of all nested attributes.
This last bug was not visible before commit 80df554275c2, because the
kernel didn't put more than two nested attributes.

Fixes: a3baf649ca9c ("[PATCH] per-task-delay-accounting: documentation")
Fixes: 80df554275c2 ("taskstats: use the libnl API to align nlattr on 64-bit")

#1418737 — [PATCH 4.2.y-ckt 148/206] hpfs: implement the show_options method

4.2.8-ckt12 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Mikulas Patocka <mikulas@twibright.com>

commit 037369b872940cd923835a0a589763180c4a36bc upstream.

The HPFS filesystem used generic_show_options to produce string that is
displayed in /proc/mounts.  However, there is a problem that the options
may disappear after remount.  If we mount the filesystem with option1
and then remount it with option2, /proc/mounts should show both option1
and option2, however it only shows option2 because the whole option
string is replaced with replace_mount_options in hpfs_remount_fs.

To fix this bug, implement the hpfs_show_options function that prints
options that are currently selected.

#1418738 — [PATCH 4.2.y-ckt 136/206] wait/ptrace: assume __WALL if the child is traced

4.2.8-ckt12 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Oleg Nesterov <oleg@redhat.com>

commit bf959931ddb88c4e4366e96dd22e68fa0db9527c upstream.

The following program (simplified version of generated by syzkaller)

	#include <pthread.h>
	#include <unistd.h>
	#include <sys/ptrace.h>
	#include <stdio.h>
	#include <signal.h>

	void *thread_func(void *arg)
	{
		ptrace(PTRACE_TRACEME, 0,0,0);
		return 0;
	}

	int main(void)
	{
		pthread_t thread;

		if (fork())
			return 0;

		while (getppid() != 1)
			;

		pthread_create(&thread, NULL, thread_func, NULL);
		pthread_join(thread, NULL);
		return 0;
	}

creates an unreapable zombie if /sbin/init doesn't use __WALL.

This is not a kernel bug, at least in a sense that everything works as
expected: debugger should reap a traced sub-thread before it can reap the
leader, but without __WALL/__WCLONE do_wait() ignores sub-threads.

Unfortunately, it seems that /sbin/init in most (all?) distributions
doesn't use it and we have to change the kernel to avoid the problem.
Note also that most init's use sys_waitid() which doesn't allow __WALL, so
the necessary user-space fix is not that trivial.

This patch just adds the "ptrace" check into eligible_child().  To some
degree this matches the "tsk->ptrace" in exit_notify(), ->exit_signal is
mostly ignored when the tracee reports to debugger.  Or WSTOPPED, the
tracer doesn't need to set this flag to wait for the stopped tracee.

This obviously means the user-visible change: __WCLONE and __WALL no
longer have any meaning for debugger.  And I can only hope that this won't
break something, but at least strace/gdb won't suffer.

We could make a more conservative change.  Say, we can take __WCLONE into
account, or !thread_group_leader().  But it would be nice to not
complicate these historical/confusing checks.

When csw->con_startup() fails in do_register_con_driver, we return no
error (i.e. 0). This was changed back in 2006 by commit 3e795de763.
Before that we used to return -ENODEV.

So fix the return value to be -ENODEV in that case again.

From: Manfred Schlaegl <manfred.schlaegl@gmx.at>

commit f49cf3b8b4c841457244c461c66186a719e13bcc upstream.

Pwm config may sleep so defer it using a worker.

On a Freescale i.MX53 based board we ran into "BUG: scheduling while
atomic" because input_inject_event locks interrupts, but
imx_pwm_config_v2 sleeps.

Tested on Freescale i.MX53 SoC with 4.6.0.

#1418744 — [PATCH 4.2.y-ckt 143/206] Input: xpad - prevent spurious input from wired Xbox 360 controllers

4.2.8-ckt12 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Cameron Gutman <aicommander@gmail.com>

commit 1ff5fa3c6732f08e01ae12f12286d4728c9e4d86 upstream.

After initially connecting a wired Xbox 360 controller or sending it
a command to change LEDs, a status/response packet is interpreted as
controller input. This causes the state of buttons represented in
byte 2 of the controller data packet to be incorrect until the next
valid input packet. Wireless Xbox 360 controllers are not affected.

Writing a new value to the LED device while holding the Start button
and running jstest is sufficient to reproduce this bug. An event will
come through with the Start button released.

Xboxdrv also won't attempt to read controller input from a packet
where byte 0 is non-zero. It also checks that byte 1 is 0x14, but
that value differs between wired and wireless controllers and this
code is shared by both. I think just checking byte 0 is enough to
eliminate unwanted packets.

The following are some examples of 3-byte status packets I saw:
01 03 02
02 03 00
03 03 03
08 03 00

#1418747 — [PATCH 4.2.y-ckt 145/206] MIPS: lib: Mark intrinsics notrace

4.2.8-ckt12 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Harvey Hunt <harvey.hunt@imgtec.com>

commit aedcfbe06558a9f53002e82d5be64c6c94687726 upstream.

On certain MIPS32 devices, the ftrace tracer "function_graph" uses
__lshrdi3() during the capturing of trace data. ftrace then attempts to
trace __lshrdi3() which leads to infinite recursion and a stack overflow.
Fix this by marking __lshrdi3() as notrace. Mark the other compiler
intrinsics as notrace in case the compiler decides to use them in the
ftrace path.

#1418751 — [PATCH 4.2.y-ckt 156/206] ARM: OMAP2+: hwmod: fix _idle() hwmod state sanity check sequence

4.2.8-ckt12 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Suman Anna <s-anna@ti.com>

commit c20c8f750d9f8f8617f07ee2352d3ff560e66bc2 upstream.

The omap_hwmod _enable() function can return success without setting
the hwmod state to _HWMOD_STATE_ENABLED for IPs with reset lines when
all of the reset lines are asserted. The omap_hwmod _idle() function
also performs a similar check, but after checking for the hwmod state
first. This triggers the WARN when pm_runtime_get and pm_runtime_put
are invoked on IPs with all reset lines asserted. Reverse the checks
for hwmod state and reset lines status to fix this.

Issue found during a unbind operation on a device with reset lines
still asserted, example backtrace below

#1418752 — [PATCH 4.2.y-ckt 162/206] ipv6, token: allow for clearing the current device token

4.2.8-ckt12 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Daniel Borkmann <daniel@iogearbox.net>

commit 47e27d5e92c46a3a62d4dfd8895b1ddb8613f531 upstream.

The original tokenized iid support implemented via f53adae4eae5 ("net: ipv6:
add tokenized interface identifier support") didn't allow for clearing a
device token as it was intended that this addressing mode was the only one
active for globally scoped IPv6 addresses. Later we relaxed that restriction
via 617fe29d45bd ("net: ipv6: only invalidate previously tokenized addresses"),
and we should also allow for clearing tokens as there's no good reason why
it shouldn't be allowed.

Fixes: 617fe29d45bd ("net: ipv6: only invalidate previously tokenized addresses")

#1418753 — [PATCH 4.2.y-ckt 166/206] PCI: Supply CPU physical address (not bus address) to iomem_is_exclusive()

4.2.8-ckt12 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Bjorn Helgaas <bhelgaas@google.com>

commit ca620723d4ff9ea7ed484eab46264c3af871b9ae upstream.

iomem_is_exclusive() requires a CPU physical address, but on some arches we
supplied a PCI bus address instead.

On most arches, pci_resource_to_user(res) returns "res->start", which is a
CPU physical address.  But on microblaze, mips, powerpc, and sparc, it
returns the PCI bus address corresponding to "res->start".

The result is that pci_mmap_resource() may fail when it shouldn't (if the
bus address happens to match an existing resource), or it may succeed when
it should fail (if the resource is exclusive but the bus address doesn't
match it).

Call iomem_is_exclusive() with "res->start", which is always a CPU physical
address, not the result of pci_resource_to_user().

#1418754 — [PATCH 4.2.y-ckt 171/206] char: Drop bogus dependency of DEVPORT on !M68K

4.2.8-ckt12 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Geert Uytterhoeven <geert@linux-m68k.org>

commit 309124e2648d668a0c23539c5078815660a4a850 upstream.

According to full-history-linux commit d3794f4fa7c3edc3 ("[PATCH] M68k
update (part 25)"), port operations are allowed on m68k if CONFIG_ISA is
defined.

However, commit 153dcc54df826d2f ("[PATCH] mem driver: fix conditional
on isa i/o support") accidentally changed an "||" into an "&&",
disabling it completely on m68k. This logic was retained when
introducing the DEVPORT symbol in commit 4f911d64e04a44c4 ("Make
/dev/port conditional on config symbol").

Drop the bogus dependency on !M68K to fix this.

#1418755 — [PATCH 4.2.y-ckt 157/206] security: drop the unused hook skb_owned_by

4.2.8-ckt12 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Paolo Abeni <pabeni@redhat.com>

commit 3c9d6296b7aee536a96ea2b53a15d23511738c1c upstream.

The skb_owned_by hook was added with the commit ca10b9e9a8ca
("selinux: add a skb_owned_by() hook") and later removed
when said commit was reverted.

Later on, when switching to list of hooks, a field named
'skb_owned_by' was included into the security_hook_head struct,
but without any users nor caller.

This commit removes the said left-over field.
