Some SoCs have a timer block enable controlled through the DSCR registers.
There is a problem in the timer64 driver initialization where the code
accesses a timer register to get the divisor used to calculate timer clock
rate. If the timer block has not been enabled when this register read takes
place, an exception is generated. This patch makes sure that the timer block
is enabled before accessing the registers.

A malicious USB device may feed in carefully crafted min/max/res values,
so that the inner loop in parse_uac2_sample_rate_range() could run for
a long time or even never terminate, e.g., given max = INT_MAX.
Also nr_rates could be a large integer, which causes an integer overflow
in the subsequent call to kmalloc() in parse_audio_format_rates_v2().
Thus, kmalloc() would allocate a smaller buffer than expected, leading
to a memory corruption.
To exploit the two vulnerabilities, an attacker needs physical access
to the machine to plug in a malicious USB device.
This patch makes two changes.
1) The type of "rate" is changed to unsigned int, so that the loop could
stop once "rate" is larger than INT_MAX.
2) Limit nr_rates to 1024.

Some devices always report percentage, despite having 0/255 as their
min/max, so add a quirk for them.
Signed-off-by: Jeremy Fitzhardinge <jeremy@goop.org>
I've sent an email earlier asking for help with a GetFeature code, and now I
have a second patch on top of Jeremy's to provide the battery functionality
for devices that support reporting it.
If I understood correctly when talking to Jeremy he said his device
never actually reported the status as an input event (sorry if I didn't
understand it correctly), and after reading HID specs I believe it's
really because it was meant to be probed, I have an Apple Keyboard and
Magic Trackpad both bluetooth batteries operated, so using PacketLogger
I saw that Mac OSX always ask the battery status using the so called
GetFeature.
What my patch does is basically:
- store the report id that matches the battery_strength
- setup the battery if 0x6.0x20 is found, even if that is reported as a feature
(as it was meant to be but only the MagicTrackpad does)
- when upower or someone access /sys/class/power_supply/hid-*/capacity it
will probe the device and return it's status.
It works great for both devices, but I have two concerns:
- the report_features function has a duplicated code
- it would be nice if it was possible for specific drivers to provide their own
probe as there might be some strange devices... (but maybe it's
already possible)
I've talked to the upower dev and he fixed it to be able to show the
right percentage.
Here how the uevent file (in /sys/class/power_supply/hid-*/) looks like:
POWER_SUPPLY_NAME=hid-00:22:41:D9:18:E7-battery
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_ONLINE=1

However, one of the conversions looks suspicious:
#define MCR0 0x00 /* Control register 0 */
+#define MCR0_RCVEN 0x0002 /* Receive enable */
+#define MCR0_XMTEN 0x1000 /* Transmission enable */
/* Init RDC private data */
- lp->mcr0 = 0x1002;
+ lp->mcr0 = MCR0_XMTEN | MCR0;
I believe what was meant here was MCR0_XMTEN | MCR0_RCVEN, which makes
sense and matches the original values.

...so that we can do the uid/gid mapping outside the asynchronous RPC
context.
This fixes a bug in the current NFSv4 atomic open code where the client
isn't able to determine what the true uid/gid fields of the file are,
(because the asynchronous nature of the OPEN call denies it the ability
to do an upcall) and so fills them with default values, marking the
inode as needing revalidation.
Unfortunately, in some cases, the VFS will do some additional sanity
checks on the file, and may override the server's decision to allow
the open because it sees the wrong owner/group fields.

Sockets can also be created through sock_clone. Because it copies
all data in the sock structure, it also copies the memcg-related pointer,
and all should be fine. However, since we now use reference counts in
socket creation, we are left with some sockets that have no reference
counts. It matters when we destroy them, since it leads to a mismatch.
