Staging: android: binder: Fix crashes when sharing a binder file between processes

2012-02-13T19:28:50+00:00

commit bd1eff9741af27378b241b347041c724bb28e857 upstream.

Opening the binder driver and sharing the file returned with
other processes (e.g. by calling fork) can crash the kernel.
Prevent these crashes with the following changes:
- Add a mutex to protect against two processes mmapping the
  same binder_proc.
- After locking mmap_sem, check that the vma we want to access
  (still) points to the same mm_struct.
- Use proc->tsk instead of current to get the files struct since
  this is where we get the rlimit from.

Staging: android: binder: Don't call dump_stack in binder_vma_open

2012-02-13T19:28:50+00:00

commit 3c1b86f17068cf6476fb2d022b9c8b44dedea2e5 upstream.

If user-space partially unmaps the driver, binder_vma_open
would dump the kernel stack. This is not a kernel bug however
and will be treated as if the whole area was unmapped once
binder_vma_close gets called.

Staging: android: mark subsystem as broken

2009-10-30T21:47:44+00:00

It's causing lots of build errors, so just mark it as broken.  It is
scheduled to be removed in 2.6.33 anyway.

staging: Make some structures static

2009-09-15T19:02:24+00:00

This was done using a semantic patch (http://coccinelle.lip6.fr/) that
checks that the declaration is not inside a function definition, that the
defined variable is not exported using EXPORTED_SYMBOL, etc, and that the
defined variable does not occur in any other file.  If these conditions
hold, static is added before the declaration.

Staging: android: lowmemorykiller: fix module param errors

2009-09-15T19:01:26+00:00

Move module_params to near the end of the source file so that
their references are already known/defined.  Fixes build errors:

drivers/staging/android/lowmemorykiller.c: In function '__check_cost':
drivers/staging/android/lowmemorykiller.c:60: error: 'lowmem_shrinker' undeclared (first use in this function)
drivers/staging/android/lowmemorykiller.c: At top level:
drivers/staging/android/lowmemorykiller.c:60: error: 'lowmem_shrinker' undeclared here (not in a function)
drivers/staging/android/lowmemorykiller.c:60: warning: type defaults to 'int' in declaration of 'type name'

Staging: android: lowmemorykiller: delete the decription file

2009-09-15T19:01:26+00:00

Move the lowmemorykiller.txt into the actual source file which is really the
correct place for it, and delete lowmemorykiller.txt.

I moved the struct shrinker down so that the predefine isn't needed.

Staging: android: binder: cleanup some long lines

2009-09-15T19:01:26+00:00

This file has a lot of long line problems due to the massive indent issues
that exist. This just cleans up some of the really really long ones.

staging: android: binder: clean up for all the stat statments

2009-09-15T19:01:25+00:00

An initial cleanup of all the binder_stat statements. The binder
command and return stats still need some assistance tho.
