staging: android: logger: Correct write offset reset on error

2013-08-04T08:50:51+00:00

commit 72bb99cfe9c57d2044445fb34bbc95b4c0bae6f2 upstream.

In the situation that a writer fails to copy data from userspace it will reset
the write offset to the value it had before it went to sleep. This discarding
any messages written while aquiring the mutex.

Therefore the reset offset needs to be retrieved after acquiring the mutex.

staging: android: logger: Allow a UID to read it's own log entries

2013-03-05T08:38:44+00:00

Modify the kernel logger to record the UID associated with
the log entries. Always allow the same UID which generated a
log message to read the log message.

Allow anyone in the logs group, or anyone with CAP_SYSLOG, to
read all log entries.

In addition, allow the client to upgrade log formats, so they
can get additional information from the kernel.

Staging: Android: logger: module_exit implementation

2012-11-27T00:01:30+00:00

This patch creates the module_exit for the android logger
so that it can be loaded and unloaded as a module.

The android logger is already declared as a tristate in the
Kconfig but the module_exit function was missing.

device_initcall works also with modprobe since include/linux/init.h:

 #define module_init(x)  __initcall(x);
 ...
 #define __initcall(fn) device_initcall(fn)

Tested against f4a75d2eb7b1e2206094b901be09adb31ba63681 Linux 3.7-rc6

staging: android: logger: Allocate logs dynamically at boot (v3)

2012-05-10T22:40:56+00:00

This changes the log initialization to be dynamic, but still
at boot time.  These changes are a predecessor to implementing
runtime allocation and freeing of logs, to make the Android logger
less hard-coded.

Change from a fixed set of static log structures, to allocation
at init time into a list.  Return proper error numbers on log
allocation failure.
