staging: hv: fix a kernel warning in netvsc_linkstatus_callback()

2011-11-11T17:42:16+00:00

commit c4b6a2eaf1c14810a4803d658f68614365978738 upstream.

netif_notify_peers() caused a kernel warning in netvsc_linkstatus_callback(),
because netvsc_linkstatus_callback() is within IRQ context. So we move
the first call to netif_notify_peers() into queued work as well, but with
zero delay.

In addition to "staging-next", this should also be back-ported to stable
kernels 2.6.32 and later.

Staging: hv: Add support for >2 TB LUN in storage driver.

2011-11-11T17:42:15+00:00

commit cf55f4a8b6243b42fb91c56d1421db0d36d60f96 upstream.

If a LUN larger than 2 TB is attached to a Linux VM on Hyper-V, we currently
report a maximum size of 2 TB. This patch resolves the issue in hv_storvsc.
Thanks to Robert Scheck  for reporting the issue.

staging: quatech_usb2: Potential lost wakeup scenario in TIOCMIWAIT

2011-11-11T17:42:15+00:00

commit e8df1674d383d2ecc6efa8d7dba74c03aafdfdd7 upstream.

If the usermode app does an ioctl over this serial device  by
using TIOCMIWAIT, then the code will wait by setting the current
task state to TASK_INTERRUPTIBLE and then calling schedule().
This will be woken up by the qt2_process_modem_status on URB
completion when the port_extra->shadowMSR is set to the new
modem status.

However, this could result in a lost wakeup scenario due to a race
in the logic in the qt2_ioctl(TIOCMIWAIT) loop and the URB completion
for new modem status in qt2_process_modem_status.
Due to this, the usermode app's task will continue to sleep despite a
change in the modem status.

staging: serqt_usb2: remove ssu100 from supported devices

2011-11-11T17:42:14+00:00

commit 7cbf3c7cd59288fb5e9f31815c74773549668d43 upstream.

The serqt_usb2 driver will not work properly with the ssu100 device
even though it claims to support it.  The ssu100 is supported by the
ssu100 driver in mainline so there is no need to have it claimed by
serqt_usb2.

staging: usbip: fix up api changes that broke windows clients

2011-11-11T17:42:13+00:00

commit 7518b9b8fc72a6c0ba67f33bdd4689c7dd28686a upstream.

Revert changes in definitions that were submitted on May 11 2011 and
committed on June 7 2011. No reason for the change in these values was
given in the patch comment, it broke compatibility with older
versions, and was difficult to detect by the simultaneous move of the
lines of code.

staging/octeon: Software should check the checksum of no tcp/udp packets

2011-09-27T15:33:06+00:00

Icmp packets with wrong checksum are never dropped since skb->ip_summed is
set to CHECKSUM_UNNECESSARY.

When icmp packets with wrong checksum pass through the octeon net driver,
the not_IP, IP_exc, L4_error hardware indicators show no error. so the
driver sets CHECKSUM_UNNECESSARY on skb->ip_summed.

L4_error only works for TCP/UDP, not for ICMP.

staging: zcache: fix cleancache crash

2011-09-20T21:17:13+00:00

After commit c5f5c4db3938 ("staging: zcache: fix crash on high memory
swap") cleancache crashes on the first successful get.  This was caused
by a remaining virt_to_page() call in zcache_pampd_get_data_and_free()
that only gets run in the cleancache path.

The patch converts the virt_to_page() to struct page casting like was
done for other instances in c5f5c4db3938.
