====================
pull-request: can 2015-07-12
this is a pull request of 8 patchs for net/master.
Sergei Shtylyov contributes 5 patches for the rcar_can driver, fixing the IRQ
check and several info and error messages. There are two patches by J.D.
Schroeder and Roger Quadros for the c_can driver and dra7x-evm device tree,
which precent a glitch in the DCAN1 pinmux. Oliver Hartkopp provides a better
approach to make the CAN skbs unique, the timestamp is replaced by a counter.

This reverts commit dec4f799d0.
Jörg Otte reports a NULL pointder dereference due to this commit, as
'crtc_state' very much can be NULL:
crtc_state = state->base.state ?
intel_atomic_get_crtc_state(state->base.state, intel_crtc) : NULL;
So the change to test 'crtc_state->base.active' cannot possibly be
correct as-is.
There may be some other minimal fix (like just checking crtc_state for
NULL), but I'm just reverting it now for the rc2 release, and people
like Daniel Vetter who actually know this code will figure out what the
right solution is in the longer term.

Commit 514ac99c64 "can: fix multiple delivery of a single CAN frame for
overlapping CAN filters" requires the skb->tstamp to be set to check for
identical CAN skbs.
Without timestamping to be required by user space applications this timestamp
was not generated which lead to commit 36c01245eb "can: fix loss of CAN frames
in raw_rcv" - which forces the timestamp to be set in all CAN related skbuffs
by introducing several __net_timestamp() calls.
This forces e.g. out of tree drivers which are not using alloc_can{,fd}_skb()
to add __net_timestamp() after skbuff creation to prevent the frame loss fixed
in mainline Linux.
This patch removes the timestamp dependency and uses an atomic counter to
create an unique identifier together with the skbuff pointer.
Btw: the new skbcnt element introduced in struct can_skb_priv has to be
initialized with zero in out-of-tree drivers which are not using
alloc_can{,fd}_skb() too.

Driver core sets "default" pinmux on on probe and CAN driver
sets "sleep" pinmux during register. This causes a small window
where the CAN pins are in "default" state with the DCAN module
being disabled.
Change the "default" state to be like sleep so this glitch is
avoided. Add a new "active" state that is used by the driver
when CAN is actually active.

The previous change 3973c526ae (net: can: c_can: Disable pins when CAN
interface is down) causes a slight glitch on the pinctrl settings when used.
Since commit ab78029 (drivers/pinctrl: grab default handles from device core),
the device core will automatically set the default pins. This causes the pins
to be momentarily set to the default and then to the sleep state in
register_c_can_dev(). By adding an optional "enable" state, boards can set the
default pin state to be disabled and avoid the glitch when the switch from
default to sleep first occurs. If the "enable" state is not available
c_can_pinctrl_select_state() falls back to using the "default" pinctrl state.

rcar_can_probe() regards 0 as a wrong IRQ #, despite platform_get_irq() that it
calls returns negative error code in that case. This leads to the following
being printed to the console when attempting to open the device:
error requesting interrupt fffffffa
because rcar_can_open() calls request_irq() with a negative IRQ #, and that
function naturally fails with -EINVAL.
Check for the negative error codes instead and propagate them upstream instead
of just returning -ENODEV.

hotplug: Prevent alloc/free of irq descriptors during cpu up/down
Normally opening a file, unlinking it and then closing will have
the inode freed upon close() (provided that it's not otherwise busy and
has no remaining links, of course). However, there's one case where that
does *not* happen. Namely, if you open it by fhandle with cold dcache,
then unlink() and close().
In normal case you get d_delete() in unlink(2) notice that dentry
is busy and unhash it; on the final dput() it will be forcibly evicted from
dcache, triggering iput() and inode removal. In this case, though, we end
up with *two* dentries - disconnected (created by open-by-fhandle) and
regular one (used by unlink()). The latter will have its reference to inode
dropped just fine, but the former will not - it's considered hashed (it
is on the ->s_anon list), so it will stay around until the memory pressure
will finally do it in. As the result, we have the final iput() delayed
indefinitely. It's trivial to reproduce -
void flush_dcache(void)
{
system("mount -o remount,rw /");
}
static char buf[20 * 1024 * 1024];
main()
{
int fd;
union {
struct file_handle f;
char buf[MAX_HANDLE_SZ];
} x;
int m;
x.f.handle_bytes = sizeof(x);
chdir("/root");
mkdir("foo", 0700);
fd = open("foo/bar", O_CREAT | O_RDWR, 0600);
close(fd);
name_to_handle_at(AT_FDCWD, "foo/bar", &x.f, &m, 0);
flush_dcache();
fd = open_by_handle_at(AT_FDCWD, &x.f, O_RDWR);
unlink("foo/bar");
write(fd, buf, sizeof(buf));
system("df ."); /* 20Mb eaten */
close(fd);
system("df ."); /* should've freed those 20Mb */
flush_dcache();
system("df ."); /* should be the same as #2 */
}
will spit out something like
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/root 322023 303843 1131 100% /
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/root 322023 303843 1131 100% /
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/root 322023 283282 21692 93% /
- inode gets freed only when dentry is finally evicted (here we trigger
than by remount; normally it would've happened in response to memory
pressure hell knows when).

This reverts commit 3cc4949269.
There is nothing wrong with coalescing during defragmentation, it
reduces truesize overhead and simplifies things for the receiving
socket (no fraglist walk needed).
However, it also destroys geometry of the original fragments.
While that doesn't cause any breakage (we make sure to not exceed largest
original size) ip_do_fragment contains a 'fastpath' that takes advantage
of a present frag list and results in fragments that (in most cases)
match what was received.
In case its needed the coalescing could be done later, when we're sure
the skb is not forwarded. But discussion during NFWS resulted in
'lets just remove this for now'.

A fairly random colletion of fixes based on -rc1 for OMAP, sunxi and
prima2 as well as a few arm64-specific DT fixes.
This series also includes a late to support a new Allwinner (sunxi)
SoC, but since it's rather simple and isolated to the
platform-specific code, it's included it for this -rc.

Reconsidering my commit 20462155 "net: inet_diag: export IPV6_V6ONLY
sockopt", I am not happy with the limitations it causes for socket
analysing code in userspace. Exporting the value only if it is set makes
it hard for userspace to decide whether the option is not set or the
kernel does not support exporting the option at all.
>From an auditor's perspective, the interesting question for listening
AF_INET6 sockets is: "Does it NOT have IPV6_V6ONLY set?" Because it is
the unexpected case. This patch allows to answer this question reliably.

====================
be2net: patch set
Hi David, the following patch set has code cleanup patches, minor enhancements
and non-critical fixes. Pls consider applying to the net-next tree. Thanks!
Patch 1 removes duplicate code in be_setup_wol() routine making it simpler
and more readable.
Patch 2 fixes the the bridge mode return value for the ndo_bridge_getlink()
call. Instead of just relying on the SRIOV enabled state, the driver now
queries the FW, for the actual mode of bridge.
Patch 3 removes code for setting D0 power state as it's already done
in pci_enable_device()
Patch 4 fixes a bad return value in be_check_ufi_compatibility() routine
introduced by an earlier commit.
Patch 5 fixes a field in udp header being accessed while in network endian
format.
Patch 6 fixes the be_mcc_notify() routine to return an error status when
the FW/HW is in an error state.
Patch 7 fixes the be_cmd_rx_filter() routine to issue the RX_FILTER cmd
and not wait for a completion from the FW. If the FW/adapter
is in an error state, this change helps in not holding up the rtnl_lock
and keeping bottom halves disabled while the driver timesout waiting for
a response from the FW.
Patch 8 fixes the be_cmd_set_loopback() routine to issue the LOOPBACK cmd
and not wait for the FW completion while spin_lock_bh() is held on the
mcc_lock. As the cmd is always issued from ethtool in a process context,
it can sleep till the FW completion is received.
Patch 9 bumps up the driver version to 10.6.0.3
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The SET_LOOPBACK_MODE command is always issued from ethtool only in a
process context. So, while waiting for the cmd to complete, the driver
can sleep instead of holding spin_lock_bh() on the mcc_lock. This is done
by calling be_mcc_notify() instead of be_mcc_notify_wait() (that returns
only after the cmd completes while the MCCQ is locked).

This fix makes the RX_FILTER cmd asynchronous, i.e., the caller issues
this cmd and doesn't wait for a completion from the FW. If the FW/adapter
is in an error state, this change helps in not holding up the rtnl_lock
and keeping bottom halves disabled while the driver timesout waiting for
a response from the FW.

The current code assumes that bridge functionality (EVB) in the adapter
is enabled only when SR-IOV is enabled. This is not always true.
