The OR has verified that his hardware distorts because of the 0 dB
offset not corresponding to the highest PCM level. Fix this by capping
said PCM level to 0 dB similarly to what we do for CX20549 (Venice).

Andreas Beckmann gave me a report that nilfs logged the following
warnings when it got a disk full:
nilfs_sufile_do_cancel_free: segment 0 must be clean
nilfs_sufile_do_cancel_free: segment 1 must be clean
These arise from a duplicate call to nilfs_segctor_cancel_freev in an
error path of log writer. This will fix the issue.

The function locomo_m62332_senddata sends a three byte i2c message to
a M62332 DAC. This entire function is guarded with a spin_lock_irqsave
at the start of the function and a spin_unlock_irqrestore at the end.
As each byte is transferred, the i2c ACK from the DAC is checked.
Currently, if the ACK is missing the function simply returns without
the unlock. It also leaves the i2c bus in an invalid state since the
last byte transferred did not have a "stop" condition and leave the
bus idle.
Fix this by adding an exit path using goto.

The locomo spi registers are all defined in locomo.h as offsets
from the first spi register LOCOMO_SPI (0x60), which is itself
an offset from the locomo base address. To correctly access
these registers LOCOMO_SPI must always be included in the
address calculation.
There are two places in locomo.c where this is not done. The
first one, in locomo_suspend, actually results in a write to
LOCOMO_ST instead of LOCOMO_SPICT. The second is in __locomo_probe
and results in a write to LOCOMO_MCSX2 instead of LOCOMO_SPIIE.
Fix these by including LOCOMO_SPI in the calculation.

TCP sessions over IPv4 can get stuck if routers between endpoints
do not fragment packets but implement PMTU instead, and we are using
those routers because of an ICMP redirect.
Setup is as follows
MTU1 MTU2 MTU1
A--------B------C------D
with MTU1 > MTU2. A and D are endpoints, B and C are routers. B and C
implement PMTU and drop packets larger than MTU2 (for example because
DF is set on all packets). TCP sessions are initiated between A and D.
There is packet loss between A and D, causing frequent TCP
retransmits.
After the number of retransmits on a TCP session reaches tcp_retries1,
tcp calls dst_negative_advice() prior to each retransmit. This results
in route cache entries for the peer to be deleted in
ipv4_negative_advice() if the Path MTU is set.
If the outstanding data on an affected TCP session is larger than
MTU2, packets sent from the endpoints will be dropped by B or C, and
ICMP NEEDFRAG will be returned. A and D receive NEEDFRAG messages and
update PMTU.
Before the next retransmit, tcp will again call dst_negative_advice(),
causing the route cache entry (with correct PMTU) to be deleted. The
retransmitted packet will be larger than MTU2, causing it to be
dropped again.
This sequence repeats until the TCP session aborts or is terminated.
Problem is fixed by removing redirected route cache entries in
ipv4_negative_advice() only if the PMTU is expired.

Some of the debug files ended up wrongly in sysfs, because at that point
of time, debugfs didn't exist. Convert these files to use debugfs and
also seq_file. This patch converts all of these files at once and then
removes the exported symbol for the Bluetooth sysfs class.
Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
When creating a high number of Bluetooth sockets (L2CAP, SCO
and RFCOMM) it is possible to scribble repeatedly on arbitrary
pages of memory. Ensure that the content of these sysfs files is
always less than one page. Even if this means truncating. The
files in question are scheduled to be moved over to debugfs in
the future anyway.

We were failing to reconnect to services due to an old authenticator, even
though we had the new ticket, because we weren't properly retrying the
connect handshake, because we were calling an old/incorrect helper that
left in_base_pos incorrect. The result was a failure to reconnect to the
OSD or MDS (with an authentication error) if the MDS restarted after the
service had been up a few hours (long enough for the original authenticator
to be invalid). This was only a problem if the AUTH_X authentication was
enabled.
Now that the 'negotiate' and 'connect' stages are fully separated, we
should use the prepare_read_connect() helper instead, and remove the
obsolete one.

Under NET_DMA, data transfer can grind to a halt when userland issues a
large read on a socket with a high RCVLOWAT (i.e., 512 KB for both).
This appears to be because the NET_DMA design queues up lots of memcpy
operations, but doesn't issue or wait for them (and thus free the
associated skbs) until it is time for tcp_recvmesg() to return.
The socket hangs when its TCP window goes to zero before enough data is
available to satisfy the read.
Periodically issue asynchronous memcpy operations, and free skbs for ones
that have completed, to prevent sockets from going into zero-window mode.

The counters in the 82599 Virtual Function are not clear on read. They
accumulate to the maximum value and then roll over. They are also not
cleared when the VF executes a soft reset, so it is possible they are
non-zero when the driver loads and starts. This has all been accounted
for in the code that keeps the stats up to date but there is one case
that is not. When the PF driver is reset the counters in the VF are
all reset to zero. This adds an additional accounting overhead into
the VF driver when the PF is reset under its feet. This patch adds
additional counters that are used by the VF driver to accumulate and
save stats after a PF reset has been detected. Prior to this patch
displaying the stats in the VF after the PF has reset would show
bogus data.
