The VD_OP_GET_VTOC operation will succeed only if the vdisk backend has a
VTOC label, otherwise it will fail. In particular, it will return error
48 (ENOTSUP) if the disk has an EFI label. VTOC disk labels are already
handled by directly reading the disk in block/partitions/sun.c (enabled by
CONFIG_SUN_PARTITION which defaults to y on SPARC). Since port->label is
unused in the driver, remove the call and the field.

Pull tracing fix from Steven Rostedt:
"ARM has system calls outside the NR_syscalls range, and the generic

Rabin Vincent added checks in the return code on syscall events to

For Renesas USB 3.0 host controller, when unplugging the usb hub which
has the RTL8153 plugged, the driver would get -EPROTO for interrupt
transfer. There is high probability to get the information of "HC died;
cleaning up", if the driver continues to submit the interrupt transfer
before the disconnect() is called.

There are laptops, such as Clevo W650SH, that only have internal

====================
netfilter/ipvs fixes for net
The following patchset contains fixes for netfilter/ipvs. This round of
fixes is larger than usual at this stage, specifically because of the
nf_tables bridge reject fixes that I would like to see in 3.18. The
patches are:
1) Fix a null-pointer dereference that may occur when logging
errors. This problem was introduced by 4a4739d56b0 ("ipvs: Pull
out crosses_local_route_boundary logic") in v3.17-rc5.
2) Update hook mask in nft_reject_bridge so we can also filter out
packets from there. This fixes 36d2af5 ("netfilter: nf_tables: allow
to filter from prerouting and postrouting"), which needs this chunk
to work.
3) Two patches to refactor common code to forge the IPv4 and IPv6
reject packets from the bridge. These are required by the nf_tables
reject bridge fix.
4) Fix nft_reject_bridge by avoiding the use of the IP stack to reject
packets from the bridge. The idea is to forge the reject packets and
inject them to the original port via br_deliver() which is now
exported for that purpose.
5) Restrict nft_reject_bridge to bridge prerouting and input hooks.
the original skbuff may cloned after prerouting when the bridge stack
needs to flood it to several bridge ports, it is too late to reject
the traffic.

Restrict the reject expression to the prerouting and input bridge
hooks. If we allow this to be used from forward or any other later
bridge hook, if the frame is flooded to several ports, we'll end up
sending several reject packets, one per cloned packet.

If the packet is received via the bridge stack, this cannot reject
packets from the IP stack.
This adds functions to build the reject packet and send it from the
bridge stack. Comments and assumptions on this patch:
1) Validate the IPv4 and IPv6 headers before further processing,
given that the packet comes from the bridge stack, we cannot assume
they are clean. Truncated packets are dropped, we follow similar
approach in the existing iptables match/target extensions that need
to inspect layer 4 headers that is not available. This also includes
packets that are directed to multicast and broadcast ethernet
addresses.
2) br_deliver() is exported to inject the reject packet via
bridge localout -> postrouting. So the approach is similar to what
we already do in the iptables reject target. The reject packet is
sent to the bridge port from which we have received the original
packet.
3) The reject packet is forged based on the original packet. The TTL
is set based on sysctl_ip_default_ttl for IPv4 and per-net
ipv6.devconf_all hoplimit for IPv6.

That can be reused by the reject bridge expression to build the reject
packet. The new functions are:

* nf_reject_ip6_tcphdr_put(): to build the TCP header.

Changes to the basic direct I/O code have broken the raw driver when reading
to the end of a raw device. Instead of returning a short read for a read that
extends partially beyond the device's end or 0 when at the end of the device,
these reads now return EIO.
The raw driver needs the same end of device handling as was added for normal
block devices. Using blkdev_read_iter, which has the needed size checks,
prevents the EIO conditions at the end of the device.

IPv6 does not allow fragmentation by routers, so there is no
fragmentation ID in the fixed header. UFO for IPv6 requires the ID to
be passed separately, but there is no provision for this in the virtio
net protocol.
Until recently our software implementation of UFO/IPv6 generated a new
ID, but this was a bug. Now we will use ID=0 for any UFO/IPv6 packet
passed through a tap, which is even worse.
Unfortunately there is no distinction between UFO/IPv4 and v6
features, so disable UFO on taps and virtio_net completely until we
have a proper solution.
We cannot depend on VM managers respecting the tap feature flags, so
keep accepting UFO packets but log a warning the first time we do
this.

If we cache them, the kernel will reuse them, independently of
whether forwarding is enabled or not. Which means that if forwarding is
disabled on the input interface where the first routing request comes
from, then that unreachable result will be cached and reused for
other interfaces, even if forwarding is enabled on them. The opposite
is also true.
This can be verified with two interfaces A and B and an output interface
C, where B has forwarding enabled, but not A and trying
ip route get $dst iif A from $src && ip route get $dst iif B from $src

The man page for open(2) indicates that when O_CREAT is specified, the
'mode' argument applies only to future accesses to the file:
Note that this mode applies only to future accesses of the newly
created file; the open() call that creates a read-only file
may well return a read/write file descriptor.
The man page for open(2) implies that 'mode' is treated identically by
O_CREAT and O_TMPFILE.
O_TMPFILE, however, behaves differently:
int fd = open("/tmp", O_TMPFILE | O_RDWR, 0);
assert(fd == -1);
assert(errno == EACCES);
int fd = open("/tmp", O_TMPFILE | O_RDWR, 0600);
assert(fd > 0);
For O_CREAT, do_last() sets acc_mode to MAY_OPEN only:
if (*opened & FILE_CREATED) {
/* Don't check for write permission, don't truncate */
open_flag &= ~O_TRUNC;
will_truncate = false;
acc_mode = MAY_OPEN;
path_to_nameidata(path, nd);
goto finish_open_created;
}
But for O_TMPFILE, do_tmpfile() passes the full op->acc_mode to
may_open().
This patch lines up the behavior of O_TMPFILE with O_CREAT. After the
inode is created, may_open() is called with acc_mode = MAY_OPEN, in
do_tmpfile().
A different, but related glibc bug revealed the discrepancy:
https://sourceware.org/bugzilla/show_bug.cgi?id=17523
The glibc lazily loads the 'mode' argument of open() and openat() using
va_arg() only if O_CREAT is present in 'flags' (to support both the 2
argument and the 3 argument forms of open; same idea for openat()).
However, the glibc ignores the 'mode' argument if O_TMPFILE is in
'flags'.
On x86_64, for open(), it magically works anyway, as 'mode' is in
RDX when entering open(), and is still in RDX on SYSCALL, which is where
the kernel looks for the 3rd argument of a syscall.
But openat() is not quite so lucky: 'mode' is in RCX when entering the
glibc wrapper for openat(), while the kernel looks for the 4th argument
of a syscall in R10. Indeed, the syscall calling convention differs from
the regular calling convention in this respect on x86_64. So the kernel
sees mode = 0 when trying to use glibc openat() with O_TMPFILE, and
fails with EACCES.

win0_lock was being used un-initialized, resulting in warning traces
being seen when lock debugging is enabled (and just wrong)

Avoid unnecessary behavior when autosuspend occurs during open().
The relative processes should only be run after finishing open().

If (tp->speed & LINK_STATUS) is not zero, the rtl8152_resume()
would call rtl_start_rx() before enabling the tx/rx. Avoid this
by resetting it to zero.

The flag of SELECTIVE_SUSPEND should be cleared when autoresuming.
Otherwise, when the system suspend and resume occur, it may have
the wrong flow.
Besides, because the flag of SELECTIVE_SUSPEND couldn't be used
to check if the hw enables the relative feature, it should alwayes
be disabled in close().

An error in the code makes the allocated space for firmware to be too
small.

Driver rtlwifi has been modified to call ieee80211_register_hw()
from the probe routine; however, the existing call in the callback
routine for deferred firmware loading was not removed.

get_btc_status
The recent changes in checking for Bluetooth status added some callbacks to code
in rtlwifi. To make certain that all callbacks are defined, a dummy routine has been
added to rtlwifi, and the drivers that need to use it are modified.

During 11n RX reordering, if there is a hole in RX table,
driver will not send packets to kernel until the rxreorder
timer expires or the table is full.
However, currently driver always restarts rxreorder timer when
receiving a packet, which causes the timer hardly to expire.
So while connected with to 11n AP in a busy environment,
ping packets may get blocked for about 30 seconds.
This patch fixes this timer restarting by ensuring rxreorder timer
would only be restarted either timer is not set or start_win
has changed.

The right shift operation has higher precedence than the mask so we
left shift by "(i * 3)" and then immediately right shift by "(i * 3)"
then we mask. It should be left shift, mask, and then right shift.
