      apparmor: fix oops, validate buffer size in apparmor_setprocattr() · 30a46a46
      Vegard Nossum authored 
      When proc_pid_attr_write() was changed to use memdup_user apparmor's
(interface violating) assumption that the setprocattr buffer was always
a single page was violated.

The size test is not strictly speaking needed as proc_pid_attr_write()
will reject anything larger, but for the sake of robustness we can keep
it in.

SMACK and SELinux look safe to me, but somebody else should probably
have a look just in case.

Based on original patch from Vegard Nossum <vegard.nossum@oracle.com>
modified for the case that apparmor provides null termination.

      ipv6: Fix mem leak in rt6i_pcpu · 903ce4ab
      Martin KaFai Lau authored 
      It was first reported and reproduced by Petr (thanks!) in
https://bugzilla.kernel.org/show_bug.cgi?id=119581

free_percpu(rt->rt6i_pcpu) used to always happen in ip6_dst_destroy().

However, after fixing a deadlock bug in
commit 9c7370a1 ("ipv6: Fix a potential deadlock when creating pcpu rt"),
free_percpu() is not called before setting non_pcpu_rt->rt6i_pcpu to NULL.

It is worth to note that rt6i_pcpu is protected by table->tb6_lock.

kmemleak somehow did not report it.  We nailed it down by
observing the pcpu entries in /proc/vmallocinfo (first suggested
by Hannes, thanks!).

      net: fix decnet rtnexthop parsing · ab58298c
      Vegard Nossum authored 
      dn_fib_count_nhs() could enter an infinite loop if nhp->rtnh_len == 0
(i.e. if userspace passes a malformed netlink message).

Let's use the helpers from net/nexthop.h which take care of all this
stuff. We can do exactly the same as e.g. fib_count_nexthops() and
fib_get_nhs() from net/ipv4/fib_semantics.c.

This fixes the softlockup for me.

      We verify "u_cmd.outsize" and "u_cmd.insize" but we need to make sure
that those values have not changed between the two copy_from_user()
calls.  Otherwise it could lead to a buffer overflow.

Additionally, cros_ec_cmd_xfer() can set s_cmd->insize to a lower value.
We should use the new smaller value so we don't copy too much data to
the user.

      ACPICA: Namespace: Fix namespace/interpreter lock ordering · 45209046
      Lv Zheng authored 
      There is a lock order issue in acpi_load_tables(). The namespace lock
is held before holding the interpreter lock.

With ACPI_MUTEX_DEBUG enabled in the kernel, this is printed to the
log during boot:

  [    0.885699] ACPI Error: Invalid acquire order: Thread 405884224 owns [ACPI_MTX_Namespace], wants [ACPI_MTX_Interpreter] (20160422/utmutex-263)
  [    0.885881] ACPI Error: Could not acquire AML Interpreter mutex (20160422/exutils-95)
  [    0.893846] ACPI Error: Mutex [0x0] is not acquired, cannot release (20160422/utmutex-326)
  [    0.894019] ACPI Error: Could not release AML Interpreter mutex (20160422/exutils-133)

The issue has been introduced by the following commit:

  Commit: 2f38b1b1
  ACPICA Commit: bfe03ffcde8ed56a7eae38ea0b188aeb12f9c52e
  Subject: ACPICA: Namespace: Fix a regression that MLC support triggers
           dead lock in dynamic table loading

Which fixed a deadlock issue for acpi_ns_load_table() in
acpi_ex_add_table() but didn't take care of the lock order in
acpi_ns_load_table() correctly.

Originally (before the above commit), ACPICA used the
namespace/interpreter locks in the following 2 key code
paths:

 1. Table loading:
 acpi_ns_load_table
	L(Namespace)
		acpi_ns_parse_table
			acpi_ns_one_complete_parse
	U(Namespace)
 2. Object evaluation:
 acpi_ns_evaluate
	L(Interpreter)
	acpi_ps_execute_method
		U(Interpreter)
		acpi_ns_load_table
			L(Namespace)
			U(Namespace)
		acpi_ev_initialize_region
			L(Namespace)
			U(Namespace)
		address_space.setup
			L(Namespace)
			U(Namespace)
		address_space.handler
			L(Namespace)
			U(Namespace)
		acpi_os_wait_semaphore
		acpi_os_acquire_mutex
		acpi_os_sleep
		L(Interpreter)
	U(Interpreter)

During runtime, while acpi_ns_evaluate is called, the lock order is
always Interpreter -> Namespace.

In turn, the problematic commit acquires the locks in the following
order:

 3. Table loading:
 acpi_ns_load_table
	L(Namespace)
		acpi_ns_parse_table
		L(Interpreter)
			acpi_ns_one_complete_parse
		U(Interpreter)
	U(Namespace)

To fix the lock order issue, move the interpreter lock to
acpi_ns_load_table() to ensure the lock order correctness:

 4. Table loading:
 acpi_ns_load_table
	L(Interpreter)
	L(Namespace)
		acpi_ns_parse_table
			acpi_ns_one_complete_parse
	U(Namespace)
	U(Interpreter)

However, this doesn't fix the current design issues related to the
namespace lock. For example, we can notice that in acpi_ns_evaluate(),
outside of acpi_ns_load_table(), the namespace objects may be created
by the named object creation control methods. And the creation of
the method-owned namespace objects are not locked by the namespace
lock. This patch doesn't try to fix such kind of existing issues.

      bonding: fix enslavement slave link notifications · a30b0168
      Aviv Heller authored 
      Currently, link notifications are not sent by
bond_set_slave_link_state() upon enslavement if
the slave is enslaved when up.

This happens because slave->link default init value
is 0, which is the same as BOND_LINK_UP, resulting
in bond_set_slave_link_state() ignoring this transition.

This patch sets the default value of slave->link to
BOND_LINK_NOCHANGE, assuring it will count as a state
transition and thus trigger notification logic.

      irqchip/mips-gic: Match IPI IRQ domain by bus token only · 547aefc4
      Paul Burton authored 
      Commit fbde2d7d ("MIPS: Add generic SMP IPI support") introduced
code which calls irq_find_matching_host with a NULL node parameter in
order to discover IPI IRQ domains which are not associated with the DT
root node's interrupt parent. This suggests that implementations of IPI
IRQ domains should effectively ignore the node parameter if it is NULL
and search purely based upon the bus token. Commit 2af70a96
("irqchip/mips-gic: Add a IPI hierarchy domain") did not do this when
implementing the GIC IPI IRQ domain, and on MIPS Boston boards this
leads to no IPI domain being discovered and a NULL pointer dereference
when attempting to send an IPI:

Fix this by allowing the GIC IPI IRQ domain to match purely based upon
the bus token if the node provided is NULL.

      irqchip/mips-gic: Map to VPs using HW VPNum · 99ec8a36
      Paul Burton authored 
      When mapping an interrupt to a VP(E) we must use the identifier for the
VP that the hardware expects, and this does not always match up with the
Linux CPU number. Commit d46812bb ("irqchip: mips-gic: Use HW IDs
for VPE_OTHER_ADDR") corrected this for the cases that existed at the
time it was written, but commit 2af70a96 ("irqchip/mips-gic: Add a
IPI hierarchy domain") added another case before the former patch was
merged. This leads to incorrectly using Linux CPU numbers when mapping
interrupts to VPs, which breaks on certain systems such as those with
multi-core I6400 CPUs. Fix by adding the appropriate call to
mips_cm_vp_id() to retrieve the expected VP identifier.

      qeth: delete napi struct when removing a qeth device · 7831b4ff
      Ursula Braun authored 
      A qeth_card contains a napi_struct linked to the net_device during
device probing. This struct must be deleted when removing the qeth
device, otherwise Panic on oops can occur when qeth devices are
repeatedly removed and added.
