IPVS: Use global mutex in ip_vs_app.c
As part of the work to make IPVS network namespace aware
__ip_vs_app_mutex was replaced by a per-namespace lock,
ipvs->app_mutex. ipvs->app_key is also supplied for debugging purposes.
Unfortunately this implementation results in ipvs->app_key residing
in non-static storage which at the very least causes a lockdep warning.
This patch takes the rather heavy-handed approach of reinstating
__ip_vs_app_mutex which will cover access to the ipvs->list_head
of all network namespaces.

veth: Fix the byte counters
Commit
44540960 "veth: move loopback logic to common location" introduced
a bug in the packet counters. I don't understand why that happened as it
is not explained in the comments and the mut check in dev_forward_skb
retains the assumption that skb->len is the total length of the packet.
I just measured this emperically by setting up a veth pair between two
noop network namespaces setting and attempting a telnet connection between
the two. I saw three packets in each direction and the byte counters were
exactly 14*3 = 42 bytes high in each direction. I got the actual
packet lengths with tcpdump.
So remove the extra ETH_HLEN from the veth byte count totals.

net ipv6: Fix duplicate /proc/sys/net/ipv6/neigh directory entries.
When I was fixing issues with unregisgtering tables under /proc/sys/net/ipv6/neigh
by adding a mount point it appears I missed a critical ordering issue, in the
ipv6 initialization. I had not realized that ipv6_sysctl_register is called
at the very end of the ipv6 initialization and in particular after we call
neigh_sysctl_register from ndisc_init.
"neigh" needs to be initialized in ipv6_static_sysctl_register which is
the first ipv6 table to initialized, and definitely before ndisc_init.
This removes the weirdness of duplicate tables while still providing a
"neigh" mount point which prevents races in sysctl unregistering.

macvlan: Fix use after free of struct macvlan_port.
When the macvlan driver was extended to call unregisgter_netdevice_queue
in
23289a37e2b127dfc4de1313fba15bb4c9f0cd5b, a use after free of struct
macvlan_port was introduced. The code in dellink relied on unregister_netdevice
actually unregistering the net device so it would be safe to free macvlan_port.
Since unregister_netdevice_queue can just queue up the unregister instead of
performing the unregiser immediately we free the macvlan_port too soon and
then the code in macvlan_stop removes the macaddress for the set of macaddress
to listen for and uses memory that has already been freed.
To fix this add a reference count to track when it is safe to free the macvlan_port
and move the call of macvlan_port_destroy into macvlan_uninit which is guaranteed
to be called after the final macvlan_port_close.

can: c_can: Do basic c_can configuration _before_ enabling the interrupts
I ran into some trouble while testing the SocketCAN driver for the BOSCH
C_CAN controller. The interface is not correctly initialized, if I put
some CAN traffic on the line, _while_ the interface is being started
(which means: the interface doesn't come up correcty, if there's some RX
traffic while doing 'ifconfig can0 up').
The current implementation enables the controller interrupts _before_
doing the basic c_can configuration. I think, this should be done the
other way round.

Reduce sequential pointer derefs in scsi_error.c and reduce size as well
This patch reduces the number of sequential pointer derefs in
drivers/scsi/scsi_error.c
This has been submitted a number of times over a couple of years. I
believe this version adresses all comments it has gathered over time.
Please apply or reject with a reason.
The benefits are:
- makes the code easier to read. Lots of sequential derefs of the same
pointers is not easy on the eye.
- theoretically at least, just dereferencing the pointers once can
allow the compiler to generally slightly faster code, so in theory
this could also be a micro speed optimization.
- reduces size of object file (tiny effect: on x86-64, in at least one
configuration, the text size decreased from 9439 bytes to 9400)
- removes some pointless (mostly trailing) whitespace.

matroxfb: remove incorrect Matrox G200eV support
Remove incorrect Matrox G200eV support that was previously added by
commit
e3a1938805d2e81b27d3d348788644f3bad004f2
A serious issue with the incorrect G200eV support that reproduces on the
Matrox G200eV equipped IBM x3650 M2 is the total lack of text (login
banner, login prompt, etc) on the console when X is not running and
total lack of text on all of the virtual consoles after X is started.
Any concerns that the incorrect code (upstream since October 2008) has
been successfully used on non-IBM G200eV equipped system(s) appear to be
unwarranted. In addition to the serious/non-intermittent nature of
issues that have been spotted on IBM systems, complete removal of the
incorrect code is clearly supported by the following Matrox (Yannick
Heneault) provided input:
"It impossible that this patch should have work on a system.
The patch only declare the G200eV as a regular G200 which is
not case. Many registers are different, including at least the
PLL programming sequence. If the G200eV is programmed like a
regular G200, it will not display anything."
v1 - Initial patch that removed the incorrect code for _all_
G200eV equipped systems.
v2 - Darrick Wong provided patch that blacklisted the incorrect
code on G200eV equipped IBM systems leaving it enabled on
all G200eV equipped non-IBM systems.
v3 - Same code changes included with v1 plus additional
justification for complete removal of the incorrect code.

Prevent rt_sigqueueinfo and rt_tgsigqueueinfo from spoofing the signal code
Userland should be able to trust the pid and uid of the sender of a
signal if the si_code is SI_TKILL.
Unfortunately, the kernel has historically allowed sigqueueinfo() to
send any si_code at all (as long as it was negative - to distinguish it
from kernel-generated signals like SIGILL etc), so it could spoof a
SI_TKILL with incorrect siginfo values.
Happily, it looks like glibc has always set si_code to the appropriate
SI_QUEUE, so there are probably no actual user code that ever uses
anything but the appropriate SI_QUEUE flag.
So just tighten the check for si_code (we used to allow any negative
value), and add a (one-time) warning in case there are binaries out
there that might depend on using other si_code values.

introduce sys_syncfs to sync a single file system
It is frequently useful to sync a single file system, instead of all
mounted file systems via sync(2):
- On machines with many mounts, it is not at all uncommon for some of
them to hang (e.g. unresponsive NFS server). sync(2) will get stuck on
those and may never get to the one you do care about (e.g., /).
- Some applications write lots of data to the file system and then
want to make sure it is flushed to disk. Calling fsync(2) on each
file introduces unnecessary ordering constraints that result in a large
amount of sub-optimal writeback/flush/commit behavior by the file
system.
There are currently two ways (that I know of) to sync a single super_block:
- BLKFLSBUF ioctl on the block device: That also invalidates the bdev
mapping, which isn't usually desirable, and doesn't work for non-block
file systems.
- 'mount -o remount,rw' will call sync_filesystem as an artifact of the
current implemention. Relying on this little-known side effect for
something like data safety sounds foolish.
Both of these approaches require root privileges, which some applications
do not have (nor should they need?) given that sync(2) is an unprivileged
operation.
This patch introduces a new system call syncfs(2) that takes an fd and
syncs only the file system it references. Maybe someday we can
$ sync /some/path
and not get
sync: ignoring all arguments
The syscall is motivated by comments by Al and Christoph at the last LSF.
syncfs(2) seems like an appropriate name given statfs(2).
A similar ioctl was also proposed a while back, see

powerpc/ptrace: Remove BUG_ON when full register set not available
In some cases during a threaded core dump not all the threads will have
a full register set. This happens when the signal causing the core dump
races with a thread exiting. The race happens when the exiting thread
has entered the kernel for the last time before the signal arrives, but
doesn't get far enough through the exit code to avoid being included
in the core dump.
So we get a thread included in the core dump which is never going to go
out to userspace again and only has a partial register set recorded
Normally we would catch each thread as it is about to go into userspace
and capture the full register set then.
However, this exiting thread is never going to go out to userspace
again, so we have no way to capture its full register set. It doesn't
really matter, though, as this is a thread which is effectively
already dead.
So instead of hitting a BUG() in this case (a really bad choice of
action in the first place), we use a poison value for the register
values.

powerpc: Make MPIC honor the "pic-no-reset" device tree property
This property, defined in the Open PIC binding, tells the kernel not to use
the reset bit in the global configuration register. Additionally, its
presence mandates that only sources which are actually used (i.e. appear in
the device tree) should have their VECPRI bits initialized.
Although, "pic-no-reset" can be used for the same use cases that
"protected-sources" is covering, the "protected-sources" implementation was
left completely intact. This is a more pragmatic approach as there are
already several existing systems which use protected sources. If
"pic-no-reset" *and* "protected-sources" are both used, however, then
"pic-no-reset" takes precedence in terms of the init behavior and the
sanity checks done by protected sources will still take place.

powerpc: Document the Open PIC device tree binding
This binding documents several properties that have been in use for quite
some time, and adds one new property 'pic-no-reset', which controls the
runtime initialization behavior of the PIC. More specifically, the presence
of 'pic-no-reset' mandates that the PIC shall not be reset during runtime
initialization and that any initialization related to interrupt sources
shall be limited to sources explicitly referenced in the device tree. This
functionality is useful in AMP systems where multiple OSes are sharing the
PIC and the reinitialization of the PIC can interfere with OSes that are
already up and running.
The interrupt specifier definition is based off of Stuart Yoder's FSL MPIC
binding.
