Staging: android: binder: fix up some checkpatch warnings

2009-06-19T18:00:52+00:00

This cleans up the majority of the checkpatch warnings in the android
binder driver.  All that is left now is a bunch of too-long-line stuff.

Staging: binder: Defer flush and release operations to avoid deadlocks.

2009-04-17T18:06:27+00:00

If a transaction that contains a file descriptor fails on a later object,
the new file descriptor needs to be closed. If this is a binder file
descriptor we would deadlock in flush. If there were no other references to
the file at this point release would also be called.

Staging: binder: Prevent the wrong thread from adding a transaction to the stack.

2009-04-17T18:06:27+00:00

If a thread is part of a transaction stack, it is only allowed to make
another call if it was the target of the top transaction on the stack.

Staging: binder: Keep a reference to the files_struct while the driver is mmapped

2009-04-17T18:06:26+00:00

This prevents breaking fget_light if a single threaded application
allows incoming file descriptors (in replies or on nodes).
Should also prevent inserting a file in the wrong files_struct if the
receving process execs in the middle of a transaction (between
task_get_unused_fd_flags and task_fd_install).

Staging: binder: Add more offset validation.

2009-04-17T18:06:26+00:00

Check that datasize is not smaller than one flat_binder_object.
Check that offsets are aligned.
Check that offsets_size is aligned.

Staging: binder: mmap fixes.

2009-04-17T18:06:26+00:00

Only allow a binder file pointer to be mmapped once. The buffer management
code cannot deal with more then one area.
Also remove leftover mutex_unlock if mmap fails.

Staging: binder: Remove VM_EXEC check.

2009-04-17T18:06:26+00:00

Many platforms do not support mappings without VM_EXEC.
