8 years agostaging: android: ram_console: honor dmesg_restrict
Nick Kralevich [Thu, 8 Mar 2012 01:34:38 +0000]
staging: android: ram_console: honor dmesg_restrict

The Linux kernel has a setting called dmesg_restrict. When true,
only processes with CAP_SYSLOG can view the kernel dmesg logs. This
helps prevent leaking of kernel information into user space.

On Android, it's possible to bypass these restrictions by viewing
/proc/last_kmsg.

This change makes /proc/last_kmsg require the same permissions as
dmesg.

Colin Cross [Thu, 8 Mar 2012 01:34:32 +0000]
staging: android: ram_console: split out persistent ram

Split ram_console into two halves.

persistent_ram is a set of apis that handle a block of memory
that does not get erased across a reboot.  It provides functions
to fill it as a single buffer or a ring buffer, and to extract
the old data after a reboot.  It handles ecc on the data to
correct bit errors introduced during reboot.

ram_console is now a small wrapper around persistent_ram that
feeds console data into the ringbuffer, and exports the old
data to /proc/last_kmsg after a reboot.

The OMAP DRM driver now calls the platform_driver_register() function
for the subordinate DMM driver inside its probe function.  This
guarantees the required order for the DMM and ensures the DMM resources

staging:iio:tsl2563 rewrite probe error handling

tsl2563 probe function has two minor issues with it's error handling paths:
1) it is silent (did not report errors to dmesg)
2) did not return failure code (mixed up use of ret and err)

and two major issues:
3) goto fail2 would corrupt a free memory pool ("double free")
4) device registration failure did NOT cancel/flush delayed work.
   (and thus dereference a freed data structure later)

The "double free" is subtle and was introduced with this change:

Originally, chip was allocated seperately. Now it's appended to the

kfree call as well (in iio_free_device()).

8 years agostaging: android/lowmemorykiller: Don't unregister notifier from atomic context
Paul E. McKenney [Wed, 7 Mar 2012 13:54:00 +0000]
staging: android/lowmemorykiller: Don't unregister notifier from atomic context

The lowmemorykiller registers an atomic notifier for notfication of when
the task is freed.  From this atomic notifier callback, it removes the
atomic notifier via task_free_unregister().  This is incorrect because
atomic_notifier_chain_unregister() calls syncronize_rcu(), which can
sleep, which shouldn't be done from an atomic notifier.

Fix this by registering the notifier during init, and only unregister it
if the lowmemorykiller is unloaded.

Staging: rtl8712/rtl8192u: move USB device ID within staging drivers.

It seems the USB device ID 0bda:8192 is wrongly assigned to the

This patch was tested with a Radicom WIFIHU embedded wireless
module with a RTL8191SU chip and the USB device ID 0bda:8192.
Without the patch the rtl8192u driver claims this device, but
it does not work. With the patch the rtl8712 driver services
this device and it works.

8 years agostaging: r8712u: Fix regression introduced by commit a5ee652
Larry Finger [Sun, 26 Feb 2012 00:10:20 +0000]
staging: r8712u: Fix regression introduced by commit a5ee652

In commit a5ee652 "staging: r8712u: Interface-state not fully tracked",
the private boolean "bup" was set false when the interface was brought down,
as that seemed appropriate. This change has not caused any problems when
using NetworkManager or manual control of the device; however, when wicd
control is used, there is a locking problem in wpa_supplicant, as shown in
https://bugzilla.kernel.org/show_bug.cgi?id=42818.

This fix reverts the only code change in commit a5ee652. My
analysis is that "bup" is badly named. In its present form, it
seems to indicate the up/down state of the device, but its usage
is more consistent with an initialized/uninitialized state. That
problem will be addressed in a later patch.

Note: Commit 8c213fa, which introdued asynchronous firmware loading
for this driver, exposed this bug to a greater extent. That bug
is addressed in the next patch in this series.

This bug is also responsible for the bug in
https://bugzilla.kernel.org/show_bug.cgi?id=42815. and this bug is
also part of the problems discussed at https://bugs.archlinux.org/task/27996#comment89950.

we were setting the len to 6 when there were 7 elements in the array.
Pavel Roskin pointed out that the intent of the code was actually to
memset() msg1.bssid.data.data[] which is a 6 character array.

Staging: crystalhd: Add global header

In the crystalhd_cmds.h there was a struct dependence bug:
the struct crystalhd_adp (which  is declared on crystalhd_lnx.h)
is used on  the crystalhd_cmd struct, however the crystalhd_lnx.h is
never included on crystalhd_cmds.h at all. Including the
crystalhd_lnx.h on crystalhd_cmds.h breaks the build,
many dependencies error occurrs, most of the type
"error: 'struct bar' has no member named 'foo'",
so I decided to reorganize the headers by adding a global header.

The gobal header crystalhd.h includes all the local headers.
The idea is that the crystalhd header will be the only included
by the others files, this will avoid the mess of many #include levels.

The order of the headers included by crystalhd.h considers the
dependencies among the headers.
