* setns:
ns: Wire up the setns system call
Done as a merge to make it easier to fix up conflicts in arm due to
addition of sendmmsg system call
|
|
32bit and 64bit on x86 are tested and working. The rest I have looked
at closely and I can't find any problems.
setns is an easy system call to wire up. It just takes two ints so I
don't expect any weird architecture porting problems.
While doing this I have noticed that we have some architectures that are
very slow to get new system calls. cris seems to be the slowest where
the last system calls wired up were preadv and pwritev. avr32 is weird
in that recvmmsg was wired up but never declared in unistd.h. frv is
behind with perf_event_open being the last syscall wired up. On h8300
the last system call wired up was epoll_wait. On m32r the last system
call wired up was fallocate. mn10300 has recvmmsg as the last system
call wired up. The rest seem to at least have syncfs wired up which was
new in the 2.6.39.
v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com>
v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm@xmission.com>
v4: Moved wiring up of the system call to another patch
v5: ported to v2.6.39-rc6
v6: rebased onto parisc-next and net-next to avoid syscall conflicts.
v7: ported to Linus's latest post 2.6.39 tree.

With the addition of a device platform mfd_cell pointer, MFD drivers
can go back to passing platform data back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.

Commit 9477c58e3308 ("ALSA: hda - Reorganize controller quriks with bit
flags") changed the driver type compares into various quirk bits.
However, the check for AZX_DCAPS_NO_TCSEL got reverted: instead of
clearing TCSEL for chipsets that have that standard capability, it
cleared then when the NO_TCSEL bit was set.
This can lead to noise and repeated sounds - a weird "echo" behavior.
As the comment just above says: "Ensuring these bits are 0 clears
playback static on some HD Audio codecs". Which is definitely true at
least on my Core i5 Westmere system.

The Panther Point chipset has an xHCI host controller that has a limit to
the number of active endpoints it can handle. Ideally, it would signal
that it can't handle anymore endpoints by returning a Resource Error for
the Configure Endpoint command, but they don't. Instead it needs software
to keep track of the number of active endpoints, across configure endpoint
commands, reset device commands, disable slot commands, and address device
commands.
Add a new endpoint context counter, xhci_hcd->num_active_eps, and use it
to track the number of endpoints the xHC has active. This gets a little
tricky, because commands to change the number of active endpoints can
fail. This patch adds a new xHCI quirk for these Intel hosts, and the new
code should not have any effect on other xHCI host controllers.
Fail a new device allocation if we don't have room for the new default
control endpoint. Use the endpoint ring pointers to determine what
endpoints were active before a Reset Device command or a Disable Slot
command, and drop those once the command completes.
Fail a configure endpoint command if it would add too many new endpoints.
We have to be a bit over zealous here, and only count the number of new
endpoints to be added, without subtracting the number of dropped
endpoints. That's because a second configure endpoint command for a
different device could sneak in before we know if the first command is
completed. If the first command dropped resources, the host controller
fails the command for some reason, and we're nearing the limit of
endpoints, we could end up oversubscribing the host.
To fix this race condition, when evaluating whether a configure endpoint
command will fix in our bandwidth budget, only add the new endpoints to
xhci->num_active_eps, and don't subtract the dropped endpoints. Ignore
changed endpoints (ones that are dropped and then re-added), as that
shouldn't effect the host's endpoint resources. When the configure
endpoint command completes, subtract off the dropped endpoints.
This may mean some configuration changes may temporarily fail, but it's
always better to under-subscribe than over-subscribe resources.
(Originally my plan had been to push the resource allocation down into the
ring allocation functions. However, that would cause us to allocate
unnecessary resources when endpoints were changed, because the xHCI driver
allocates a new ring for the changed endpoint, and only deletes the old
ring once the Configure Endpoint command succeeds. A further complication
would have been dealing with the per-device endpoint ring cache.)

The xHCI host controller in the Panther Point chipset sometimes produces
spurious events on the event ring. If it receives a short packet, it
first puts a Transfer Event with a short transfer completion code on the
event ring. Then it puts a Transfer Event with a successful completion
code on the ring for the same TD. The xHCI driver correctly processes the
short transfer completion code, gives the URB back to the driver, and then
prints a warning in dmesg about the spurious event. These warning
messages really fill up dmesg when an HD webcam is plugged into xHCI.
This spurious successful event behavior isn't technically disallowed by
the xHCI specification, so make the xHCI driver just ignore the spurious
completion event.

The Intel Panther Point chipsets contain an EHCI and xHCI host controller
that shares some number of skew-dependent ports. These ports can be
switched from the EHCI to the xHCI host (and vice versa) by a hardware MUX
that is controlled by registers in the xHCI PCI configuration space. The
USB 3.0 SuperSpeed terminations on the xHCI ports can be controlled
separately from the USB 2.0 data wires.
This switchover mechanism is there to support users who do a custom
install of certain non-Linux operating systems that don't have official
USB 3.0 support. By default, the ports are under EHCI, SuperSpeed
terminations are off, and USB 3.0 devices will show up under the EHCI
controller at reduced speeds. (This was more palatable for the marketing
folks than having completely dead USB 3.0 ports if no xHCI drivers are
available.) Users should be able to turn on xHCI by default through a
BIOS option, but users are happiest when they don't have to change random
BIOS settings.
This patch introduces a driver method to switchover the ports from EHCI to
xHCI before the EHCI driver finishes PCI enumeration. We want to switch
the ports over before the USB core has the chance to enumerate devices
under EHCI, or boot from USB mass storage will fail if the boot device
connects under EHCI first, and then gets disconnected when the port
switches over to xHCI.
Add code to the xHCI PCI quirk to switch the ports from EHCI to xHCI. The
PCI quirks code will run before any other PCI probe function is called, so
this avoids the issue with boot devices.
Another issue is with BIOS behavior during system resume from hibernate.
If the BIOS doesn't support xHCI, it may switch the devices under EHCI to
allow use of the USB keyboard, mice, and mass storage devices. It's
supposed to remember the value of the port routing registers and switch
them back when the OS attempts to take control of the xHCI host controller,
but we all know not to trust BIOS writers.
Make both the xHCI driver and the EHCI driver attempt to switchover the
ports in their PCI resume functions. We can't guarantee which PCI device
will be resumed first, so this avoids any race conditions. Writing a '1'
to an already set port switchover bit or a '0' to a cleared port switchover
bit should have no effect.
The xHCI PCI configuration registers will be documented in the EDS-level
chipset spec, which is not public yet. I have permission from legal and
the Intel chipset group to release this patch early to allow good Linux
support at product launch. I've tried to document the registers as much
as possible, so please let me know if anything is unclear.

perf_evsel__alloc_fd allocates an array of file descriptors with the
memory initialized to 0. The array has dimensions for cpus and threads.
Later, __perf_evsel__open calls sys_perf_event_open for each cpu and thread
dimensions. If the open fails for any of the cpus or threads then the fd's
for this event are closed and the fd entry in the array is set to -1. Now,
if the first attempt fails for the event (e.g., the event is not supported)
the remaining dimensions (cpu > 0 and thread > 0) are not touched and left
at the initialized value of 0.
builtin-stat catches ENOENT and ENOSYS failures and allows the command to
continue. The end result is that stat attempts to read from an fd of 0 which
of course is stdin and so the command hangs until you type ctrl-D.
Resolve by initializing the array to -1 since an fd < 0 is already
handled.

Ingo Molnar noticed that we have this unnecessary ratelimit.h
dependency in linux/net.h, which hid compilation problems from
people doing builds only with CONFIG_NET enabled.
Move this stuff out to a seperate net/net_ratelimit.h file and
include that in the only two places where this thing is needed.

Several networking headers were depending upon the implicit
linux/sysctl.h include they get when including linux/net.h
Add explicit includes.

Several crashes in cleanup_once() were reported in recent kernels.
Commit d6cc1d642de9 (inetpeer: various changes) added a race in
unlink_from_unused().
One way to avoid taking unused_peers.lock before doing the list_empty()
test is to catch 0->1 refcnt transitions, using full barrier atomic
operations variants (atomic_cmpxchg() and atomic_inc_return()) instead
of previous atomic_inc() and atomic_add_unless() variants.
We then call unlink_from_unused() only for the owner of the 0->1
transition.
Add a new atomic_add_unless_return() static helper
With help from Arun Sharma.

It's currently exposed only through /proc which, besides requiring
screen-scraping, doesn't allow userspace to distinguish between two
identical ATM adapters with different ATM indexes. The ATM device index
is required when using PPPoATM on a system with multiple ATM adapters.
