e8cfe00943 UBI: cleanup LEB start calculations
Wrong macro was used in calculating the data offset: UBI_EC_HDR_SIZE instead of
UBI_VID_HDR_SIZE. The data offset should be VID header offset + VID header size
(aligned to the minimum I/O unit).

This was not a bug only because currently UBI_EC_HDR_SIZE and UBI_VID_HDR_SIZE
have the same value of 64 bytes.

Commit message was amended by Artem.

d4c6381303 UBI: fix NOR erase preparation quirk
In 'nor_erase_prepare()' we want to make sure the UBI headers are
corrupted. But it is possible that one of the headers just contains
all 0xFFs, which is also OK, because UBI will erase it in case of
a power cut.

9fc3bbb4a7 ipv4/route.c: respect prefsrc for local routes
The preferred source address is currently ignored for local routes,
which results in all local connections having a src address that is the
same as the local dst address. Fix this by respecting the preferred source
address when it is provided for local routes.

This bug can be demonstrated as follows:

 # ifconfig dummy0 192.168.0.1
 # ip route show table local | grep local.*dummy0
 local 192.168.0.1 dev dummy0  proto kernel  scope host  src 192.168.0.1
 # ip route change table local local 192.168.0.1 dev dummy0 \
     proto kernel scope host src 127.0.0.1
 # ip route show table local | grep local.*dummy0
 local 192.168.0.1 dev dummy0  proto kernel  scope host  src 127.0.0.1

We now establish a local connection and verify the source IP
address selection:

 # nc -l 192.168.0.1 3128 &
 # nc 192.168.0.1 3128 &
 # netstat -ant | grep 192.168.0.1:3128.*EST
 tcp        0      0 192.168.0.1:3128        192.168.0.1:33228 ESTABLISHED
 tcp        0      0 192.168.0.1:33228       192.168.0.1:3128  ESTABLISHED

867c202654 ima: fix add LSM rule bug
If security_filter_rule_init() doesn't return a rule, then not everything
is as fine as the return code implies.

This bug only occurs when the LSM (eg. SELinux) is disabled at runtime.

Adding an empty LSM rule causes ima_match_rules() to always succeed,
ignoring any remaining rules.

 default IMA TCB policy:
  # PROC_SUPER_MAGIC
  dont_measure fsmagic=0x9fa0
  # SYSFS_MAGIC
  dont_measure fsmagic=0x62656572
  # DEBUGFS_MAGIC
  dont_measure fsmagic=0x64626720
  # TMPFS_MAGIC
  dont_measure fsmagic=0x01021994
  # SECURITYFS_MAGIC
  dont_measure fsmagic=0x73636673

  < LSM specific rule >
  dont_measure obj_type=var_log_t

  measure func=BPRM_CHECK
  measure func=FILE_MMAP mask=MAY_EXEC
  measure func=FILE_CHECK mask=MAY_READ uid=0

Thus without the patch, with the boot parameters 'tcb selinux=0', adding
the above 'dont_measure obj_type=var_log_t' rule to the default IMA TCB
measurement policy, would result in nothing being measured.  The patch
prevents the default TCB policy from being replaced.

e6f26129eb bridge: stp: ensure mac header is set
commit bf9ae5386b
(llc: use dev_hard_header) removed the
skb_reset_mac_header call from llc_mac_hdr_init.

This seems fine itself, but br_send_bpdu() invokes ebtables LOCAL_OUT.

We oops in ebt_basic_match() because it assumes eth_hdr(skb) returns
a meaningful result.

The function can't be __init itself (being called from some sysfs

2f32c86721 atl1: fix oops when changing tx/rx ring params
Commit 3f5a2a713a zeroes out the statistics
message block (SMB) and coalescing message block (CMB) when adapter ring
resources are freed.  This is desirable behavior, but, as a side effect,
the commit leads to an oops when atl1_set_ringparam() attempts to alter
the number of rx or tx elements in the ring buffer (by using ethtool
-G, for example).  We don't want SMB or CMB to change during this
operation.

Modify atl1_set_ringparam() to preserve SMB and CMB when changing ring
parameters.

24c7855774 ARM: pxa: fix page table corruption on resume
Before this patch, the following error would sometimes occur after a
resume on pxa3xx:

    /path/to/mm/memory.c:144: bad pmd 8040542e.

The problem was that a temporary page table mapping was being improperly
restored.

The PXA3xx resume code creates a temporary mapping of resume_turn_on_mmu
to avoid a prefetch abort.  The pxa3xx_resume_after_mmu code requires
that the r1 register holding the address of this mapping not be
modified, however, resume_turn_on_mmu does modify it. It is mostly
correct in that r1 receives the base table address, but it may also
get other bits in 13:0.  This results in pxa3xx_resume_after_mmu
restoring the original mapping to the wrong place, corrupting memory
and leaving the temporary mapping in place.

d425de5436 perf: Fix callchain hit bad cast on ascii display
ipchain__fprintf_graph() casts the number of hits in a branch as an
int, which means we lose its highests bits.

This results in meaningless number of callchain hits in perf.data
that have a high number of hits recorded, typically those that have
callchain branches hits appearing more than INT_MAX. This happens
easily as those are pondered by the event period.

Commit 56543af "starfire: use BUILD_BUG_ON for netdrv_addr_t" revealed
that the preprocessor condition used to find the size of dma_addr_t
yielded the wrong result for some architectures and configurations.
This was kluged for 64-bit PowerPC in commit 3e502e6 by adding yet
another case to the condition.  However, 64-bit MIPS configurations
are not detected reliably either.

This should be fixed by using CONFIG_ARCH_DMA_ADDR_T_64BIT, but that
isn't yet defined everywhere it should be.

2393c944d5 ISDN, Gigaset: Fix memory leak in do_disconnect_req()
Hi,

In drivers/isdn/gigaset/capi.c::do_disconnect_req() we will leak the
memory allocated (with kmalloc) to 'b3cmsg' if the call to alloc_skb()
fails.

...
		b3cmsg = kmalloc(sizeof(*b3cmsg), GFP_KERNEL);
	allocation here ------^
		if (!b3cmsg) {
			dev_err(cs->dev, "%s: out of memory\n", __func__);
			send_conf(iif, ap, skb, CAPI_MSGOSRESOURCEERR);
			return;
		}
		capi_cmsg_header(b3cmsg, ap->id, CAPI_DISCONNECT_B3, CAPI_IND,
				 ap->nextMessageNumber++,
				 cmsg->adr.adrPLCI | (1 << 16));
		b3cmsg->Reason_B3 = CapiProtocolErrorLayer1;
		b3skb = alloc_skb(CAPI_DISCONNECT_B3_IND_BASELEN, GFP_KERNEL);
		if (b3skb == NULL) {
			dev_err(cs->dev, "%s: out of memory\n", __func__);
			send_conf(iif, ap, skb, CAPI_MSGOSRESOURCEERR);
			return;
	leak here ------^
...

This leak is easily fixed by just kfree()'ing the memory allocated to
'b3cmsg' right before we return. The following patch does that.

e983dc2428 Revert "Staging: zram: work around oops due to startup ordering snafu"
This reverts commit 7e24cce38a because it
was never appropriate for mainline.

Do not check for init flag before starting I/O - zram module is unusable
without this fix.

The oops mentioned in the reverted commit message was actually a problem
only with the zram version as present in project's own repository where
we allocate struct zram_stats_cpu upon device initialization.  OTOH, In
mainline/staging version of zram, we allocate struct stats upfront, so
this oops cannot happen in mainline version.

Checking for init_done flag in zram_make_request() results in a *no-op*
for any I/O operation since we simply always return success.  This flag
is actually set when the first write occurs on a zram disk which
triggers its initialization.

ebb76ce16d memcg: fix wrong VM_BUG_ON() in try_charge()'s mm->owner check
At __mem_cgroup_try_charge(), VM_BUG_ON(!mm->owner) is checked.
But as commented in mem_cgroup_from_task(), mm->owner can be NULL
in some racy case. This check of VM_BUG_ON() is bad.

A possible story to hit this is at swapoff()->try_to_unuse(). It passes
mm_struct to mem_cgroup_try_charge_swapin() while mm->owner is NULL. If we
can't get proper mem_cgroup from swap_cgroup information, mm->owner is used
as charge target and we see NULL.
