4a60570dce hwmon: (pmbus/core) Treat parameters as paged if on multiple pages
Some chips have attributes which exist on more than one page but the
attribute is not presently marked as paged. This causes the attributes
to be generated with the same label, which makes it impossible for
userspace to tell them apart.

Marking all such attributes as paged would result in the page suffix
being added regardless of whether they were present on more than one
page or not, which might break existing setups. Therefore, we add a
second check which treats the attribute as paged, even if not marked as
such, if it is present on multiple pages.

Adamski, Krzysztof (Nokia - PL/Wroclaw)
38463721ec hwmon: (pmbus/core) mutex_lock write in pmbus_set_samples
update_lock is a mutex intended to protect write operations. It was not
taken, however, when _pmbus_write_word_data is called from
pmbus_set_samples() function which may cause problems especially when
some PMBUS_VIRT_* operation is implemented as a read-modify-write cycle.

This patch makes sure the lock is held during the operation.

c41dd48e21 hwmon: (core) add thermal sensors only if dev->of_node is present
Drivers may register to hwmon and request for also registering
with the thermal subsystem (HWMON_C_REGISTER_TZ). However,
some of these driver, e.g. marvell phy, may be probed from
Device Tree or being dynamically allocated, and in the later
case, it will not have a dev->of_node entry.

Registering with hwmon without the dev->of_node may result in
different outcomes depending on the device tree, which may
be a bit misleading. If the device tree blob has no 'thermal-zones'
node, the *hwmon_device_register*() family functions are going
to gracefully succeed, because of-thermal,
*thermal_zone_of_sensor_register() return -ENODEV in this case,
and the hwmon error path handles this error code as success to
cover for the case where CONFIG_THERMAL_OF is not set.
However, if the device tree blob has the 'thermal-zones'
entry, the *hwmon_device_register*() will always fail on callers
with no dev->of_node, propagating -EINVAL.

If dev->of_node is not present, calling of-thermal does not
make sense. For this reason, this patch checks first if the
device has a of_node before going over the process of registering
with the thermal subsystem of-thermal interface. And in this case,
when a caller of *hwmon_device_register*() with HWMON_C_REGISTER_TZ
and no dev->of_node will still register with hwmon, but not with
the thermal subsystem. If all the hwmon part bits are in place,
the registration will succeed.

4970b42d5c Revert "fib_rules: return 0 directly if an exactly same rule exists when NLM_F_EXCL not supplied"
This reverts commit e9919a24d3.

Nathan reported the new behaviour breaks Android, as Android just add
new rules and delete old ones.

If we return 0 without adding dup rules, Android will remove the new
added rules and causing system to soft-reboot.

930b9a0543 net: aquantia: fix wol configuration not applied sometimes
WoL magic packet configuration sometimes does not work due to
couple of leakages found.

Mainly there was a regression introduced during readx_poll refactoring.

Next, fw request waiting time was too small. Sometimes that
caused sleep proxy config function to return with an error
and to skip WoL configuration.
At last, WoL data were passed to FW from not clean buffer.
That could cause FW to accept garbage as a random configuration data.

0ee4e76937 ethtool: fix potential userspace buffer overflow
ethtool_get_regs() allocates a buffer of size ops->get_regs_len(),
and pass it to the kernel driver via ops->get_regs() for filling.

There is no restriction about what the kernel drivers can or cannot do
with the open ethtool_regs structure. They usually set regs->version
and ignore regs->len or set it to the same size as ops->get_regs_len().

But if userspace allocates a smaller buffer for the registers dump,
we would cause a userspace buffer overflow in the final copy_to_user()
call, which uses the regs.len value potentially reset by the driver.

To fix this, make this case obvious and store regs.len before calling
ops->get_regs(), to only copy as much data as requested by userspace,
up to the value returned by ops->get_regs_len().

While at it, remove the redundant check for non-null regbuf.

The problem was that the peer.cookie value points to an skb allocated
area on the first pass through this function, at which point it is
overwritten with a heap allocated value, but in certain cases, where a
COOKIE_ECHO chunk is included in the packet, a second pass through
sctp_process_init is made, where the cookie value is re-allocated,
leaking the first allocation.

Fix is to always allocate the cookie value, and free it when we are done
using it.

b50e058746 net: rds: fix memory leak when unload rds_rdma
When KASAN is enabled, after several rds connections are
created, then "rmmod rds_rdma" is run. The following will
appear.

"
BUG rds_ib_incoming (Not tainted): Objects remaining

 entry_SYSCALL_64_after_hwframe+0x44/0xa9
"
This is rds connection memory leak. The root cause is:
When "rmmod rds_rdma" is run, rds_ib_remove_one will call
rds_ib_dev_shutdown to drop the rds connections.
rds_ib_dev_shutdown will call rds_conn_drop to drop rds
connections as below.
"
rds_conn_path_drop(&conn->c_path[0], false);
"
In the above, destroy is set to false.
void rds_conn_path_drop(struct rds_conn_path *cp, bool destroy)
{
        atomic_set(&cp->cp_state, RDS_CONN_ERROR);

        rcu_read_lock();
        if (!destroy && rds_destroy_pending(cp->cp_conn)) {
                rcu_read_unlock();
                return;
        }
        queue_work(rds_wq, &cp->cp_down_w);
        rcu_read_unlock();
}
In the above function, destroy is set to false. rds_destroy_pending
is called. This does not move rds connections to ib_nodev_conns.
So destroy is set to true to move rds connections to ib_nodev_conns.
In rds_ib_unregister_client, flush_workqueue is called to make rds_wq
finsh shutdown rds connections. The function rds_ib_destroy_nodev_conns
is called to shutdown rds connections finally.
Then rds_ib_recv_exit is called to destroy slab.

void rds_ib_recv_exit(void)
{
        kmem_cache_destroy(rds_ib_incoming_slab);
        kmem_cache_destroy(rds_ib_frag_slab);
}
The above slab memory leak will not occur again.

>From tests,
256 rds connections
[root@ca-dev14 ~]# time rmmod rds_rdma

real    0m16.522s
user    0m0.000s

real    0m32.054s
user    0m0.000s
sys     0m15.568s

To rmmod rds_rdma with 256 rds connections, about 16 seconds are needed.
And with 512 rds connections, about 32 seconds are needed.
>From ftrace, when one rds connection is destroyed,

"
 19)               |  rds_conn_destroy [rds]() {
 19)   7.782 us    |    rds_conn_path_drop [rds]();
 15)               |  rds_shutdown_worker [rds]() {

 15)   7.195 us    |    }
 15) + 11.434 us   |  }
 19)   2.285 us    |    rds_cong_remove_conn [rds]();
 19) * 24062.76 us |  }
"
So if many rds connections will be destroyed, this function
rds_ib_destroy_nodev_conns uses most of time.

b7999b0772 ipv6: fix the check before getting the cookie in rt6_get_cookie
In Jianlin's testing, netperf was broken with 'Connection reset by peer',
as the cookie check failed in rt6_check() and ip6_dst_check() always
returned NULL.

It's caused by Commit 93531c6743 ("net/ipv6: separate handling of FIB
entries from dst based routes"), where the cookie can be got only when
'c1'(see below) for setting dst_cookie whereas rt6_check() is called
when !'c1' for checking dst_cookie, as we can see in ip6_dst_check().

Since in ip6_dst_check() both rt6_dst_from_check() (c1) and rt6_check()
(!c1) will check the 'from' cookie, this patch is to remove the c1 check
in rt6_get_cookie(), so that the dst_cookie can always be set properly.

c1:
  (rt->rt6i_flags & RTF_PCPU || unlikely(!list_empty(&rt->rt6i_uncached)))

0a90478b93 ipv4: not do cache for local delivery if bc_forwarding is enabled
With the topo:

    h1 ---| rp1            |
          |     route  rp3 |--- h3 (192.168.200.1)
    h2 ---| rp2            |

If rp1 bc_forwarding is set while rp2 bc_forwarding is not, after
doing "ping 192.168.200.255" on h1, then ping 192.168.200.255 on
h2, and the packets can still be forwared.

This issue was caused by the input route cache. It should only do
the cache for either bc forwarding or local delivery. Otherwise,
local delivery can use the route cache for bc forwarding of other
interfaces.

This patch is to fix it by not doing cache for local delivery if
all.bc_forwarding is enabled.

Note that we don't fix it by checking route cache local flag after
rt_cache_valid() in "local_input:" and "ip_mkroute_input", as the
common route code shouldn't be touched for bc_forwarding.

 "The contains two small patches to the pidfd samples and test binaries
  respectively.

  They were lacking appropriate ifdefines for __NR_pidfd_send_signal and
  could hence lead to compilation errors when that was not defined.

  This was spotted on mips independently by Guenter Roeck (who was kind
  enough to send a fix for the samples binary) and Arnd who spotted it
  in linux-next.

  Apart from these two patches, there's also a patch to update the
  comments for the pidfd_send_signal() syscall which were slightly
  wrong/inconsistenly worded"

a48bc52001 nvme-pci: don't limit DMA segement size
NVMe uses PRPs (or optionally unlimited SGLs) for data transfers and
has no specific limit for a single DMA segement.  Limiting the size
will cause problems because the block layer assumes PRP-ish devices
using a virt boundary mask don't have a segment limit.  And while this
is true, we also really need to tell the DMA mapping layer about it,
otherwise dma-debug will trip over it.

s390/qeth: fixes 2019-06-05

one more shot...  now with patch 2 fixed up so that it uses the
dst entry returned from dst_check().

From the v1 cover letter:

Please apply the following set of qeth fixes to -net.

- The first two patches fix issues in the L3 driver's cast type
  selection for transmitted skbs.
- Alexandra adds a sanity check when retrieving VLAN information from
  neighbour address events.
- The last patch adds some missing error handling for qeth's new
  multiqueue code.

335726195e s390/qeth: fix VLAN attribute in bridge_hostnotify udev event
Enabling sysfs attribute bridge_hostnotify triggers a series of udev events
for the MAC addresses of all currently connected peers. In case no VLAN is
set for a peer, the device reports the corresponding MAC addresses with
VLAN ID 4096. This currently results in attribute VLAN=4096 for all
non-VLAN interfaces in the initial series of events after host-notify is
enabled.

Instead, no VLAN attribute should be reported in the udev event for
non-VLAN interfaces.

Only the initial events face this issue. For dynamic changes that are
reported later, the device uses a validity flag.

This also changes the code so that it now sets the VLAN attribute for
MAC addresses with VID 0. On Linux, no qeth interface will ever be
registered with VID 0: Linux kernel registers VID 0 on all network
interfaces initially, but qeth will drop .ndo_vlan_rx_add_vid for VID 0.
Peers with other OSs could register MACs with VID 0.

0cd6783d3c s390/qeth: check dst entry before use
While qeth_l3 uses netif_keep_dst() to hold onto the dst, a skb's dst
may still have been obsoleted (via dst_dev_put()) by the time that we
end up using it. The dst then points to the loopback interface, which
means the neighbour lookup in qeth_l3_get_cast_type() determines a bogus
cast type of RTN_BROADCAST.
For IQD interfaces this causes us to place such skbs on the wrong
HW queue, resulting in TX errors.

Fix-up the various call sites to first validate the dst entry with
dst_check(), and fall back accordingly.

72c87976c5 s390/qeth: handle limited IPv4 broadcast in L3 TX path
When selecting the cast type of a neighbourless IPv4 skb (eg. on a raw
socket), qeth_l3 falls back to the packet's destination IP address.
For this case we should classify traffic sent to 255.255.255.255 as
broadcast.
This fixes DHCP requests, which were misclassified as unicast
(and for IQD interfaces thus ended up on the wrong HW queue).

3e1d0452ed ceph: avoid iput_final() while holding mutex or in dispatch thread
iput_final() may wait for reahahead pages. The wait can cause deadlock.
For example:

    Call Trace:

     worker_thread+0x4b/0x460
     kthread+0x105/0x140
     ret_from_fork+0x22/0x40

In above example, truncate_inode_pages_range() waits for readahead pages
while holding s_mutex. ceph_check_caps() waits for s_mutex and blocks
OSD dispatch thread. Later OSD replies (for readahead) can't be handled.

ceph_check_caps() also may lock snap_rwsem for read. So similar deadlock
can happen if iput_final() is called while holding snap_rwsem.

In general, it's not good to call iput_final() inside MDS/OSD dispatch
threads or while holding any mutex.

The fix is introducing ceph_async_iput(), which calls iput_final() in
workqueue.

ce0e22f5d8 drm/amdgpu: fix ring test failure issue during s3 in vce 3.0 (V2)
[What]
vce ring test fails consistently during resume in s3 cycle, due to
mismatch read & write pointers.
On debug/analysis its found that rptr to be compared is not being
correctly updated/read, which leads to this failure.
Below is the failure signature:
	[drm:amdgpu_vce_ring_test_ring] *ERROR* amdgpu: ring 12 test failed
	[drm:amdgpu_device_ip_resume_phase2] *ERROR* resume of IP block <vce_v3_0> failed -110
	[drm:amdgpu_device_resume] *ERROR* amdgpu_device_ip_resume failed (-110).

[How]
fetch rptr appropriately, meaning move its read location further down
in the code flow.
With this patch applied the s3 failure is no more seen for >5k s3 cycles,
which otherwise is pretty consistent.

V2: remove reduntant fetch of rptr
