dccp: Fix panic caused by too early termination of retransmission mechanism
Thanks is due to Wei Yongjun for the detailed analysis and description of this
bug at http://marc.info/?l=dccp&m=121739364909199&w=2
The problem is that invalid packets received by a client in state REQUEST cause
the retransmission timer for the DCCP-Request to be reset. This includes freeing
the Request-skb ( in dccp_rcv_request_sent_state_process() ). As a consequence,
* the arrival of further packets cause a double-free, triggering a panic(),
* the connection then may hang, since further retransmissions are blocked.
This patch changes the order of statements so that the retransmission timer is
reset, and the pending Request freed, only if a valid Response has arrived (or
the number of sysctl-retries has been exhausted).
Further changes:
----------------
To be on the safe side, replaced __kfree_skb with kfree_skb so that if due to
unexpected circumstances the sk_send_head is NULL the WARN_ON is used instead.

The git commit 7c5026aa9b81dd45df8d3f4e0be73e485976a8b6 ("tg3: Add

previous firmware events to be serviced before attempting to submit a
new event. Unfortunately that patch contained a bug that cause the
driver to wait 2.5 seconds, rather than 2.5 milliseconds as intended.
This patch fixes that bug.
This bug revealed that not all firmware versions service driver events
though. Since we do not know which versions of the firmware do and don't
service these events, the driver needs some way to minimize the effects
of the delay. This patch solves the problem by recording a jiffies
timestamp when it submits an event to the hardware. If the jiffies
counter shows that 2.5 milliseconds have already passed, a wait is not
needed and the driver can proceed to submit a new event.

These drivers should not be relying on CONFIG_USB_DEBUG. By doing this,
it prevents users of kernels that do not enable this option from

usb: cdc-acm: drain writes on close
Add a mechanism to let the write queue drain naturally before
closing the TTY, rather than always losing that data. There
is a timeout, so it can't wait too long.
Provide missing locking inside acm_wb_is_avail(); it matters
more now. Note, this presumes an earlier patch was applied,
removing a call to this routine where the lock was held.
Slightly improved diagnostics on write URB completion, so we
can tell when a write URB gets killed and, if so, how much
data it wrote first ... and so that I/O path is normally
silent (and can't much change timings).

usb: cdc-acm: stop dropping tx buffers
The "increase cdc-acm write throughput" patch left in place two
now-obsolete mechanisms, either of which can make the cdc-acm
driver drop TX data (nasty!). This patch removes them:
- The write_ready flag ... if an URB and buffer were found,
they can (and should!) always be used.
- TX path acm_wb_is_used() ... used when the buffer was just
allocated, so that check is pointless.
Also fix a won't-yet-matter leak of a write buffer on a disconnect path.

usb gadget: issue notifications from ACM function
Update the CDC-ACM gadget code to support the peripheral-to-host
notifications when the tty is opened or closed, or issues a BREAK.
The serial framework code calls new generic hooks; right now only
CDC-ACM uses those hooks. This resolves several REVISIT comments
in the code. (Based on a patch from Felipe Balbi.)
Note that this doesn't expose USB_CDC_CAP_BRK to the host, since
this code still rejects USB_CDC_REQ_SEND_BREAK control requests
for host-to-peripheral BREAK signaling (received via /dev/ttyGS*).

ISP1760 requires a delay of 90ns between programming the address and
reading the data. Current driver solves this by a mdelay(1) which is
very heavy weighted and slow. This patch applies the workaround from
the ISP1760 FAQ by using two different banks for PTD and payload data
and using a common wait for them. This wait is done by an additional
ISP1760 access (whose timing constraints guarantee the 90ns delay).
This improves speed when reading from an USB stick from:
$ time dd if=/dev/sda of=/dev/zero bs=65536 count=1638
real 1m 15.43s
user 0m 0.44s
sys 0m 39.46s

USB: serial gadget: rx path data loss fixes
Update RX path handling in new serial gadget code to cope better with
RX blockage: queue every RX packet until its contents can safely be
passed up to the ldisc. Most of the RX path work is now done in the
RX tasklet, instead of just the final "push to ldisc" step. This
addresses some cases of data loss:
- A longstanding serial gadget bug: when tty_insert_flip_string()
didn't copy the entire buffer, the rest of the characters were
dropped! Now that packet stays queued until the rest of its data
is pushed to the ldisc.
- Another longstanding issue: in the unlikely case that an RX
transfer returns data and also reports a fault, that data is
no longer discarded.
- In the recently added RX throttling logic: it needs to stop
pushing data into the TTY layer, instead of just not submitting
new USB read requests. When the TTY is throttled long enough,
backpressure will eventually make the OUT endpoint NAK.
Also: an #ifdef is removed (no longer necessary); and start switching
to a better convention for debug messages (prefix them with tty name).
