====================
drivers: net: cpsw: phy-handle fixes
This series fixes a number of related issues around using phy-handle
properties in cpsw emac nodes.
Patch 1 fixes a bug if more than one slave is used, and either
slave uses the phy-handle property in the devicetree.
Patch 2 fixes a NULL pointer dereference which can occur if a
phy-handle property is used and of_phy_connect() return NULL,
such as with a bad devicetree.
Patch 3 fixes an issue where the phy-mode property would be ignored
if a phy-handle property was used. This also fixes a bogus error
message that would be emitted.
Patch 4 fixes makes the binding documentation more explicit that
exactly one PHY property should be used, and also marks phy_id as
deprecated.
Patch 5 cleans up the fixed-link case to work like the now-fixed
phy-handle case.
I have tested on the following hardware configurations:
- (EVMSK) dual emac, phy_id property in both slaves
- (EVMSK) dual emac, phy-handle property in both slaves
- (EVMSK) a bad phy-handle property pointing to &mmc1
- (EVMSK) phy_id property with incorrect PHY address
- (BeagleBoneBlack) single emac, phy_id property
- (custom) single emac, fixed-link subnode
Andrew Goodbody reported testing v2 on a board that doesn't use
dual_emac mode, but with 2 PHYs using phy-handle properties [1].
Nicolas Chauvet reported testing v2 on an HP t410 (dm8148).
Markus Brunner reported testing v1 on the following [2]:
- emac0 with phy_id and emac1 with fixed phy
- emac0 with phy-handle and emac1 with fixed phy
- emac0 with fixed phy and emac1 with fixed phy

drivers: net: cpsw: use of_phy_connect() in fixed-link case
If a fixed-link DT subnode is used, the phy_device was looked up so
that a PHY ID string could be constructed and passed to phy_connect().
This is not necessary, as the device_node can be passed directly to
of_phy_connect() instead. This reuses the same codepath as if the
phy-handle DT property was used.

drivers: net: cpsw: fix segfault in case of bad phy-handle
If an emac node has a phy-handle property that points to something
which is not a phy, then a segmentation fault will occur when the
interface is brought up. This is because while phy_connect() will
return ERR_PTR() on failure, of_phy_connect() will return NULL.
The common error check uses IS_ERR(), and so missed when
of_phy_connect() fails. The NULL pointer is then dereferenced.
Also, the common error message referenced slave->data->phy_id,
which would be empty in the case of phy-handle. Instead, use the
name of the device_node as a useful identifier. And in the phy_id
case add the error code for completeness.

Commit
9e42f715264ff158478fa30eaed847f6e131366b ("drivers: net: cpsw: add

field. However, phy connections are per-slave, so the phy_node field should
be in cpsw_slave_data rather than cpsw_priv.
This would go unnoticed in a single emac configuration. But in dual_emac
mode, the last "phy-handle" property parsed for either slave would be used
by both of them, causing them both to refer to the same phy_device.

====================
pegasus: correct buffer & packet sizes
As noticed by Lincoln Ramsay <
a1291762@gmail.com> some old (usb 1.1) Pegasus
based devices may actually return more bytes than the specified in the datasheet
amount. That would not be a problem if the allocated space for the SKB was
equal to the parameter passed to usb_fill_bulk_urb(). Some poor bugger (i
really hope it was not me, but 'git blame' is useless in this case, so anyway)
decided to add '+ 8' to the buffer length parameter. Sometimes the usb transfer
overflows and corrupts the socket structure, leading to kernel panic.
The above doesn't seem to happen for newer (Pegasus2 based) devices which did
help this bug to hide for so long.
The new default is to not include the CRC at the end of each received package.
So far CRC has been ignored which makes no sense to do it in a first place.
The patch is against v4.6-rc5 and was tested on ADM8515 device by transferring
multiple gigabytes of data over a couple of days without any complaints from the
kernel. Please apply it to whatever net tree you deem fit.

- split the patch in two parts;

devpts: more pty driver interface cleanups
This is more prep-work for the upcoming pty changes. Still just code
cleanup with no actual semantic changes.
This removes a bunch pointless complexity by just having the slave pty
side remember the dentry associated with the devpts slave rather than
the inode. That allows us to remove all the "look up the dentry" code
for when we want to remove it again.
Together with moving the tty pointer from "inode->i_private" to
"dentry->d_fsdata" and getting rid of pointless inode locking, this
removes about 30 lines of code. Not only is the end result smaller,
it's simpler and easier to understand.
The old code, for example, depended on the d_find_alias() to not just
find the dentry, but also to check that it is still hashed, which in
turn validated the tty pointer in the inode.
That is a _very_ roundabout way to say "invalidate the cached tty
pointer when the dentry is removed".
The new code just does
dentry->d_fsdata = NULL;
in devpts_pty_kill() instead, invalidating the tty pointer rather more
directly and obviously. Don't do something complex and subtle when the
obvious straightforward approach will do.
The rest of the patch (ie apart from code deletion and the above tty
pointer clearing) is just switching the calling convention to pass the
dentry or file pointer around instead of the inode.

bpf: fix double-fdput in replace_map_fd_with_map_ptr()
When bpf(BPF_PROG_LOAD, ...) was invoked with a BPF program whose bytecode
references a non-map file descriptor as a map file descriptor, the error
handling code called fdput() twice instead of once (in __bpf_map_get() and
in replace_map_fd_with_map_ptr()). If the file descriptor table of the
current task is shared, this causes f_count to be decremented too much,
allowing the struct file to be freed while it is still in use
(use-after-free). This can be exploited to gain root privileges by an
unprivileged user.
This bug was introduced in
commit
0246e64d9a5f ("bpf: handle pseudo BPF_LD_IMM64 insn"), but is only
exploitable since
commit
1be7f75d1668 ("bpf: enable non-root eBPF programs") because
previously, CAP_SYS_ADMIN was required to reach the vulnerable code.

net: ipv6: Delete host routes on an ifdown
It was a simple idea -- save IPv6 configured addresses on a link down
so that IPv6 behaves similar to IPv4. As always the devil is in the
details and the IPv6 stack as too many behavioral differences from IPv4
making the simple idea more complicated than it needs to be.
The current implementation for keeping IPv6 addresses can panic or spit
out a warning in one of many paths:
1. IPv6 route gets an IPv4 route as its 'next' which causes a panic in
rt6_fill_node while handling a route dump request.
2. rt->dst.obsolete is set to DST_OBSOLETE_DEAD hitting the WARN_ON in
fib6_del
3. Panic in fib6_purge_rt because rt6i_ref count is not 1.
The root cause of all these is references related to the host route for
an address that is retained.
So, this patch deletes the host route every time the ifdown loop runs.
Since the host route is deleted and will be re-generated an up there is
no longer a need for the l3mdev fix up. On the 'admin up' side move
addrconf_permanent_addr into the NETDEV_UP event handling so that it
runs only once versus on UP and CHANGE events.
All of the current panics and warnings appear to be related to
addresses on the loopback device, but given the catastrophic nature when
a bug is triggered this patch takes the conservative approach and evicts
all host routes rather than trying to determine when it can be re-used
and when it can not. That can be a later optimizaton if desired.

drivers: firmware: psci: unify enable-method binding on ARM {64,32}-bit systems
Currently ARM CPUs DT bindings allows different enable-method value for
PSCI based systems. On ARM 64-bit this property is required and must be
"psci" while on ARM 32-bit systems this property is optional and must
be "arm,psci" if present.
However, "arm,psci" has always been the compatible string for the PSCI
node, and was never intended to be the enable-method. So this is a bug
in the binding and not a deliberate attempt at specifying 32-bit
differently.
This is problematic if 32-bit OS is run on 64-bit system which has
"psci" as enable-method rather than the expected "arm,psci".
So let's unify the value into "psci" and remove support for "arm,psci"
before it finds any users.

net: stmmac: socfpga: Remove re-registration of reset controller
Both socfpga_dwmac_parse_data() in dwmac-socfpga.c and stmmac_dvr_probe()
in stmmac_main.c functions call devm_reset_control_get() to register an
reset controller for the stmmac. This results in an attempt to register
two reset controllers for the same non-shared reset line.
The first attempt to register the reset controller works fine. The second
attempt fails with warning from the reset controller core, see below.
The warning is produced because the reset line is non-shared and thus
it is allowed to have only up-to one reset controller associated with
that reset line, not two or more.
The solution has multiple parts. First, the original socfpga_dwmac_init()
is tweaked to use reset controller pointer from the stmmac_priv (private
data of the stmmac core) instead of the local instance, which was used
before. The local re-registration of the reset controller is removed.
Next, the socfpga_dwmac_init() is moved after stmmac_dvr_probe() in the
probe function. This order is legal according to Altera and it makes the
code much easier, since there is no need to temporarily register and
unregister the reset controller ; the reset controller is already registered
by the stmmac_dvr_probe().
Finally, plat_dat->exit and socfpga_dwmac_exit() is no longer necessary,
since the functionality is already performed by the stmmac core.

When switchdev PORT_MDB succeeded and adds a multicast group, a completion
callback is been invoked "br_mdb_complete". The completion function
locks the multicast_lock and finds the right net_bridge_port_group and
marks it as offloaded.

_batadv_update_route rcu_derefences orig_ifinfo->router outside of a
spinlock protected region to print some information messages to the debug
log. But this pointer is not checked again when the new pointer is assigned
in the spinlock protected region. Thus is can happen that the value of
orig_ifinfo->router changed in the meantime and thus the reference counter
of the wrong router gets reduced after the spinlock protected region.
Just rcu_dereferencing the value of orig_ifinfo->router inside the spinlock

batman-adv: Deactivate TO_BE_ACTIVATED hardif on shutdown
The shutdown of an batman-adv interface can happen with one of its slave
interfaces still being in the BATADV_IF_TO_BE_ACTIVATED state. A possible
reason for it is that the routing algorithm BATMAN_V was selected and
batadv_schedule_bat_ogm was not yet called for this interface. This slave
interface still has to be set to BATADV_IF_INACTIVE or the batman-adv
interface will never reduce its usage counter and thus never gets shutdown.
This problem can be simulated via:
$ modprobe dummy
$ modprobe batman-adv routing_algo=BATMAN_V
$ ip link add bat0 type batadv
$ ip link set dummy0 master bat0
$ ip link set dummy0 up
$ ip link del bat0

Merge "ARM: i.MX fixes for 4.6" from Shawn Guo:
The i.MX fixes for 4.6:
- The sdhci-esdhc-imx DMA support is broken due to commit
7b91369b4655
("mmc: sdhci: Set DMA mask when adding host"). It requires device's
dma_mask be set up properly to get DMA work. The fixing patch
initializes the DMA mask to enable the access again.

Fixes for omaps for v4.6-rc cycle:
- Clockdomain fix for dra7 timer interrupts
- Two fixes for GPMC EDMA binding, I missed the need for a merge with
GPMC changes and EDMA changes
- Fix beagle-x15 eSATA by dropping misconfigured extcon_usb1
- Fix occasional external aborts on 36xx with PM that we've been
chasing for past few months. It turned out to be duplicate restore
of INTC registers that can in some cases cause us to hit erratum 1.106.
