ENGR00284988 Camera recording kernel crash on WFD source

2013-10-25T09:20:40+00:00

Fix kernel crash issue meet when do 720p Camera recording
on WFD source side, the crash is related with timer schedule,
fixed by add protection code in gckOS_StartTimer function.

ENGR00278452 PU: fix system hang if run Audio loop test

2013-10-23T10:00:26+00:00

cpufreq and pu power management will oprate the same register, it looks should
keep them operating in order not concurrent. Then use the cpufreq mutex in xPU
driver to make sure.
Another code bug is in pu power management which base regulator framework, we
set the reister directly not regulator, then there is the chance set_volatage
will miss the chance if this time voltage setting as the last time setting
before PU disable, but we have to do this, so add regulator_sync_voltage to
force sync the voltage setting. The drawback is setting twice...

Note:
This patch is temporary and supposed to be replaced it once we find the
root cause.

netfilter: qtaguid: rate limit some of the printks

2013-09-26T01:51:33+00:00

Some of the printks are in the packet handling path.
We now ratelimit the very unlikely errors to avoid
kmsg spamming.

netfilter: xt_qtaguid: Allow tracking loopback

2013-09-26T01:51:21+00:00

In the past it would always ignore interfaces with loopback addresses.
Now we just treat them like any other.
This also helps with writing tests that check for the presence
of the qtaguid module.

netfilter: xt_qtaguid: extend iface stat to report protocols

2013-09-26T01:51:13+00:00

In the past the iface_stat_fmt would only show global bytes/packets
for the skb-based numbers.
For stall detection in userspace, distinguishing tcp vs other protocols
makes it easier.
Now we report
  ifname total_skb_rx_bytes total_skb_rx_packets total_skb_tx_bytes
  total_skb_tx_packets {rx,tx}_{tcp,udp,ohter}_{bytes,packets}

netfilter: xt_qtaguid: remove AID_* dependency for access control

2013-09-26T01:50:59+00:00

qtaguid limits what can be done with /ctrl and /stats based on group
membership.
This changes removes AID_NET_BW_STATS and AID_NET_BW_ACCT, and picks
up the groups from the gid of the matching proc entry files.

netfilter: xt_qtaguid: fix error exit that would keep a spinlock.

2013-09-26T01:44:10+00:00

qtudev_open() could return with a uid_tag_data_tree_lock held
when an kzalloc(..., GFP_ATOMIC) would fail.
Very unlikely to get triggered AND survive the mayhem of running out of mem.
