binder: use freezable blocking calls Avoid waking up every thread sleeping in a binder call during suspend and resume by calling a freezable blocking call. Previous patches modified the freezer to avoid sending wakeups to threads that are blocked in freezable blocking calls. This call was selected to be converted to a freezable call because it doesn't hold any locks or release any resources when interrupted that might be needed by another freezing task or a kernel driver during suspend, and is a common site where idle userspace tasks are blocked.

pidns: Use task_active_pid_ns where appropriate The expressions tsk->nsproxy->pid_ns and task_active_pid_ns aka ns_of_pid(task_pid(tsk)) should have the same number of cache line misses with the practical difference that ns_of_pid(task_pid(tsk)) is released later in a processes life. Furthermore by using task_active_pid_ns it becomes trivial to write an unshare implementation for the the pid namespace. So I have used task_active_pid_ns everywhere I can. In fork since the pid has not yet been attached to the process I use ns_of_pid, to achieve the same effect. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com>

Add security hooks to binder and implement the hooks for SELinux. Add security hooks to the binder and implement the hooks for SELinux. The security hooks enable security modules such as SELinux to implement controls over binder IPC. The security hooks include support for controlling what process can become the binder context manager (binder_set_context_mgr), controlling the ability of a process to invoke a binder transaction/IPC to another process (binder_transaction), controlling the ability of a process to transfer a binder reference to another process (binder_transfer_binder), and controlling the ability of a process to transfer an open file to another process (binder_transfer_file). These hooks have been included in the Android kernel trees since Android 4.3. (Updated to reflect upstream relocation and changes to the binder driver, changes to the LSM audit data structures, coding style cleanups, and to add inline documentation for the hooks).

Staging: android: binder: Fix crashes when sharing a binder file between processes 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: binder: Support concurrent 32 bit and 64 bit processes. For 64bit systems we want to use the same binder interface for 32bit and 64bit processes. Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes. This change replaces all the uses of void* and size_t with binder_uintptr_t and binder_size_t. These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace. This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for compatability, which if set which enables the old protocol, setting BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems. Please note that all 64bit kernels will use the 64bit Binder ABI.

expose a low-level variant of fd_install() for binder Similar situation to that of __alloc_fd(); do not use unless you really have to. You should not touch any descriptor table other than your own; it's a sure sign of a really bad API design. As with __alloc_fd(), you *must* use a first-class reference to struct files_struct; something obtained by get_files_struct(some task) (let alone direct task->files) will not do. It must be either current->files, or obtained by get_files_struct(current) by the owner of that sucker and given to you. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

staging: binder: Support concurrent 32 bit and 64 bit processes. For 64bit systems we want to use the same binder interface for 32bit and 64bit processes. Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes. This change replaces all the uses of void* and size_t with binder_uintptr_t and binder_size_t. These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace. This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for compatability, which if set which enables the old protocol, setting BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems. Please note that all 64bit kernels will use the 64bit Binder ABI.

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

android: binder: fix binder mmap failures binder_update_page_range() initializes only addr and size fields in 'struct vm_struct tmp_area;' and passes it to map_vm_area(). Before 71394fe50146 ("mm: vmalloc: add flag preventing guard hole allocation") this was because map_vm_area() didn't use any other fields in vm_struct except addr and size. Now get_vm_area_size() (used in map_vm_area()) reads vm_struct's flags to determine whether vm area has guard hole or not. binder_update_page_range() don't initialize flags field, so this causes following binder mmap failures: -----------[ cut here ]------------ WARNING: CPU: 0 PID: 1971 at mm/vmalloc.c:130 vmap_page_range_noflush+0x119/0x144() CPU: 0 PID: 1971 Comm: healthd Not tainted 4.0.0-rc1-00399-g7da3fdc-dirty #157 Hardware name: ARM-Versatile Express [<c001246d>] (unwind_backtrace) from [<c000f7f9>] (show_stack+0x11/0x14) [<c000f7f9>] (show_stack) from [<c049a221>] (dump_stack+0x59/0x7c) [<c049a221>] (dump_stack) from [<c001cf21>] (warn_slowpath_common+0x55/0x84) [<c001cf21>] (warn_slowpath_common) from [<c001cfe3>] (warn_slowpath_null+0x17/0x1c) [<c001cfe3>] (warn_slowpath_null) from [<c00c66c5>] (vmap_page_range_noflush+0x119/0x144) [<c00c66c5>] (vmap_page_range_noflush) from [<c00c716b>] (map_vm_area+0x27/0x48) [<c00c716b>] (map_vm_area) from [<c038ddaf>] (binder_update_page_range+0x12f/0x27c) [<c038ddaf>] (binder_update_page_range) from [<c038e857>] (binder_mmap+0xbf/0x1ac) [<c038e857>] (binder_mmap) from [<c00c2dc7>] (mmap_region+0x2eb/0x4d4) [<c00c2dc7>] (mmap_region) from [<c00c3197>] (do_mmap_pgoff+0x1e7/0x250) [<c00c3197>] (do_mmap_pgoff) from [<c00b35b5>] (vm_mmap_pgoff+0x45/0x60) [<c00b35b5>] (vm_mmap_pgoff) from [<c00c1f39>] (SyS_mmap_pgoff+0x5d/0x80) [<c00c1f39>] (SyS_mmap_pgoff) from [<c000ce81>] (ret_fast_syscall+0x1/0x5c) ---[ end trace 48c2c4b9a1349e54 ]--- binder: 1982: binder_alloc_buf failed to map page at f0e00000 in kernel binder: binder_mmap: 1982 b6bde000-b6cdc000 alloc small buf failed -12 Use map_kernel_range_noflush() instead of map_vm_area() as this is better API for binder's purposes and it allows to get rid of 'vm_struct tmp_area' at all.

staging: binder: Support concurrent 32 bit and 64 bit processes. For 64bit systems we want to use the same binder interface for 32bit and 64bit processes. Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes. This change replaces all the uses of void* and size_t with binder_uintptr_t and binder_size_t. These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace. This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for compatability, which if set which enables the old protocol, setting BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems. Please note that all 64bit kernels will use the 64bit Binder ABI.

These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace. This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for compatability, which if set which enables the old protocol, setting BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems. Please note that all 64bit kernels will use the 64bit Binder ABI.

staging: binder: Support concurrent 32 bit and 64 bit processes. For 64bit systems we want to use the same binder interface for 32bit and 64bit processes. Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes. This change replaces all the uses of void* and size_t with binder_uintptr_t and binder_size_t. These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace. This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for compatability, which if set which enables the old protocol, setting BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems.

staging: binder: Support concurrent 32 bit and 64 bit processes. For 64bit systems we want to use the same binder interface for 32bit and 64bit processes. Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes. This change replaces all the uses of void* and size_t with binder_uintptr_t and binder_size_t. These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace. This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for compatability, which if set which enables the old protocol, setting BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems. Please note that all 64bit kernels will use the 64bit Binder ABI.

staging: android: binder: fix alignment issues The Android userspace aligns the data written to the binder buffers to 4bytes. Thus for 32bit platforms or 64bit platforms running an 32bit Android userspace we can have a buffer looking like this: platform buffer(binder_cmd pointer) size 32/32 32b 32b 8B 64/32 32b 64b 12B 64/64 32b 64b 12B Thus the kernel needs to check that the buffer size is aligned to 4bytes not to (void *) that will be 8bytes on 64bit machines. The change does not affect existing 32bit ABI.

staging: android: binder: fix binder interface for 64bit compat layer The changes in this patch will fix the binder interface for use on 64bit machines and stand as the base of the 64bit compat support. The changes apply to the structures that are passed between the kernel and userspace. Most of the changes applied mirror the change to struct binder_version where there is no need for a 64bit wide protocol_version(on 64bit machines). The change inlines with the existing 32bit userspace(the structure has the same size) and simplifies the compat layer such that the same handler can service the BINDER_VERSION ioctl.

Add security hooks to binder and implement the hooks for SELinux. Add security hooks to the binder and implement the hooks for SELinux. The security hooks enable security modules such as SELinux to implement controls over binder IPC. The security hooks include support for controlling what process can become the binder context manager (binder_set_context_mgr), controlling the ability of a process to invoke a binder transaction/IPC to another process (binder_transaction), controlling the ability of a process to transfer a binder reference to another process (binder_transfer_binder), and controlling the ability of a process to transfer an open file to another process (binder_transfer_file). These hooks have been included in the Android kernel trees since Android 4.3. (Updated to reflect upstream relocation and changes to the binder driver, changes to the LSM audit data structures, coding style cleanups, and to add inline documentation for the hooks).

staging: binder: Support concurrent 32 bit and 64 bit processes. For 64bit systems we want to use the same binder interface for 32bit and 64bit processes. Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes. This change replaces all the uses of void* and size_t with binder_uintptr_t and binder_size_t. These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace. This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for compatability, which if set which enables the old protocol, setting BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems. Please note that all 64bit kernels will use the 64bit Binder ABI.

staging: android: binder: fix alignment issues The Android userspace aligns the data written to the binder buffers to 4bytes. Thus for 32bit platforms or 64bit platforms running an 32bit Android userspace we can have a buffer looking like this: platform buffer(binder_cmd pointer) size 32/32 32b 32b 8B 64/32 32b 64b 12B 64/64 32b 64b 12B Thus the kernel needs to check that the buffer size is aligned to 4bytes not to (void *) that will be 8bytes on 64bit machines. The change does not affect existing 32bit ABI.

Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes. This change replaces all the uses of void* and size_t with binder_uintptr_t and binder_size_t. These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace.

staging: android: binder: fix binder interface for 64bit compat layer The changes in this patch will fix the binder interface for use on 64bit machines and stand as the base of the 64bit compat support. The changes apply to the structures that are passed between the kernel and userspace. Most of the changes applied mirror the change to struct binder_version where there is no need for a 64bit wide protocol_version(on 64bit machines). The change inlines with the existing 32bit userspace(the structure has the same size) and simplifies the compat layer such that the same handler can service the BINDER_VERSION ioctl. Other changes make use of kernel types as well as user-exportable ones and fix format specifier issues. The changes do not affect existing 32bit ABI.

This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace. This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for compatability, which if set which enables the old protocol, setting BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems. Please note that all 64bit kernels will use the 64bit Binder ABI.

staging: android: binder: fix binder interface for 64bit compat layer The changes in this patch will fix the binder interface for use on 64bit machines and stand as the base of the 64bit compat support. The changes apply to the structures that are passed between the kernel and userspace. Most of the changes applied mirror the change to struct binder_version where there is no need for a 64bit wide protocol_version(on 64bit machines). The change inlines with the existing 32bit userspace(the structure has the same size) and simplifies the compat layer such that the same handler can service the BINDER_VERSION ioctl. Other changes make use of kernel types as well as user-exportable ones and fix format specifier issues. The changes do not affect existing 32bit ABI.

Add security hooks to binder and implement the hooks for SELinux. Add security hooks to the binder and implement the hooks for SELinux. The security hooks enable security modules such as SELinux to implement controls over binder IPC. The security hooks include support for controlling what process can become the binder context manager (binder_set_context_mgr), controlling the ability of a process to invoke a binder transaction/IPC to another process (binder_transaction), controlling the ability of a process to transfer a binder reference to another process (binder_transfer_binder), and controlling the ability of a process to transfer an open file to another process (binder_transfer_file). These hooks have been included in the Android kernel trees since Android 4.3. (Updated to reflect upstream relocation and changes to the binder driver, changes to the LSM audit data structures, coding style cleanups, and to add inline documentation for the hooks).

staging: binder: Support concurrent 32 bit and 64 bit processes. For 64bit systems we want to use the same binder interface for 32bit and 64bit processes. Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes. This change replaces all the uses of void* and size_t with binder_uintptr_t and binder_size_t. These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace. This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for compatability, which if set which enables the old protocol, setting BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems. Please note that all 64bit kernels will use the 64bit Binder ABI.

staging: binder: Support concurrent 32 bit and 64 bit processes. For 64bit systems we want to use the same binder interface for 32bit and 64bit processes. Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes. This change replaces all the uses of void* and size_t with binder_uintptr_t and binder_size_t. These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace. This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for compatability, which if set which enables the old protocol, setting BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems. Please note that all 64bit kernels will use the 64bit Binder ABI.

staging: binder: Support concurrent 32 bit and 64 bit processes. For 64bit systems we want to use the same binder interface for 32bit and 64bit processes. Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes. This change replaces all the uses of void* and size_t with binder_uintptr_t and binder_size_t.

Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes.

These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace.

staging: binder: Support concurrent 32 bit and 64 bit processes. For 64bit systems we want to use the same binder interface for 32bit and 64bit processes. Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes. This change replaces all the uses of void* and size_t with binder_uintptr_t and binder_size_t. These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace. This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for compatability, which if set which enables the old protocol, setting BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems. Please note that all 64bit kernels will use the 64bit Binder ABI.

Previous patches modified the freezer to avoid sending wakeups to threads that are blocked in freezable blocking calls. This call was selected to be converted to a freezable call because it doesn't hold any locks or release any resources when interrupted that might be needed by another freezing task or a kernel driver during suspend, and is a common site where idle userspace tasks are blocked.

staging: binder: Support concurrent 32 bit and 64 bit processes. For 64bit systems we want to use the same binder interface for 32bit and 64bit processes. Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes. This change replaces all the uses of void* and size_t with binder_uintptr_t and binder_size_t. These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace. This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for compatability, which if set which enables the old protocol, setting BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems. Please note that all 64bit kernels will use the 64bit Binder ABI.

pidns: Use task_active_pid_ns where appropriate The expressions tsk->nsproxy->pid_ns and task_active_pid_ns aka ns_of_pid(task_pid(tsk)) should have the same number of cache line misses with the practical difference that ns_of_pid(task_pid(tsk)) is released later in a processes life. Furthermore by using task_active_pid_ns it becomes trivial to write an unshare implementation for the the pid namespace. So I have used task_active_pid_ns everywhere I can. In fork since the pid has not yet been attached to the process I use ns_of_pid, to achieve the same effect. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com>

staging: binder: Support concurrent 32 bit and 64 bit processes. For 64bit systems we want to use the same binder interface for 32bit and 64bit processes. Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes. This change replaces all the uses of void* and size_t with binder_uintptr_t and binder_size_t. These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace. This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for compatability, which if set which enables the old protocol, setting BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems. Please note that all 64bit kernels will use the 64bit Binder ABI.

Add security hooks to binder and implement the hooks for SELinux. Add security hooks to the binder and implement the hooks for SELinux. The security hooks enable security modules such as SELinux to implement controls over binder IPC. The security hooks include support for controlling what process can become the binder context manager (binder_set_context_mgr), controlling the ability of a process to invoke a binder transaction/IPC to another process (binder_transaction), controlling the ability of a process to transfer a binder reference to another process (binder_transfer_binder), and controlling the ability of a process to transfer an open file to another process (binder_transfer_file). These hooks have been included in the Android kernel trees since Android 4.3. (Updated to reflect upstream relocation and changes to the binder driver, changes to the LSM audit data structures, coding style cleanups, and to add inline documentation for the hooks).

staging: binder: add vm_fault handler An issue was observed when a userspace task exits. The page which hits error here is the zero page. In binder mmap, the whole of vma is not mapped. On a task crash, when debuggerd reads the binder regions, the unmapped areas fall to do_anonymous_page in handle_pte_fault, due to the absence of a vm_fault handler. This results in zero page being mapped. Later in zap_pte_range, vm_normal_page returns zero page in the case of VM_MIXEDMAP and it results in the error.

When it encountered a reference without a death notification request, it would skip looking at the remaining references, and therefore fail to send death notifications for them.

staging: binder: Support concurrent 32 bit and 64 bit processes. For 64bit systems we want to use the same binder interface for 32bit and 64bit processes. Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes. This change replaces all the uses of void* and size_t with binder_uintptr_t and binder_size_t. These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace. This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for compatability, which if set which enables the old protocol, setting BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems. Please note that all 64bit kernels will use the 64bit Binder ABI.

hlist: drop the node parameter from iterators I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually. The semantic patch which is mostly the work of Peter Senna Tschudin is here: @@ iterator name hlist_for_each_entry, hlist_for_each_entry_continue, hlist_for_each_entry_from, hlist_for_each_entry_rcu, hlist_for_each_entry_rcu_bh, hlist_for_each_entry_continue_rcu_bh, for_each_busy_worker, ax25_uid_for_each, ax25_for_each, inet_bind_bucket_for_each, sctp_for_each_hentry, sk_for_each, sk_for_each_rcu, sk_for_each_from, sk_for_each_safe, sk_for_each_bound, hlist_for_each_entry_safe, hlist_for_each_entry_continue_rcu, nr_neigh_for_each, nr_neigh_for_each_safe, nr_node_for_each, nr_node_for_each_safe, for_each_gfn_indirect_valid_sp, for_each_gfn_sp, for_each_host; type T; expression a,c,d,e; identifier b; statement S; @@ -T b; <+... when != b ( hlist_for_each_entry(a, - b, c, d) S | hlist_for_each_entry_continue(a, - b, c) S | hlist_for_each_entry_from(a, - b, c) S | hlist_for_each_entry_rcu(a, - b, c, d) S | hlist_for_each_entry_rcu_bh(a, - b, c, d) S | hlist_for_each_entry_continue_rcu_bh(a, - b, c) S | for_each_busy_worker(a, c, - b, d) S | ax25_uid_for_each(a, - b, c) S | ax25_for_each(a, - b, c) S | inet_bind_bucket_for_each(a, - b, c) S | sctp_for_each_hentry(a, - b, c) S | sk_for_each(a, - b, c) S | sk_for_each_rcu(a, - b, c) S | sk_for_each_from -(a, b) +(a) S + sk_for_each_from(a) S | sk_for_each_safe(a, - b, c, d) S | sk_for_each_bound(a, - b, c) S | hlist_for_each_entry_safe(a, - b, c, d, e) S | hlist_for_each_entry_continue_rcu(a, - b, c) S | nr_neigh_for_each(a, - b, c) S | nr_neigh_for_each_safe(a, - b, c, d) S | nr_node_for_each(a, - b, c) S | nr_node_for_each_safe(a, - b, c, d) S | - for_each_gfn_sp(a, c, d, b) S + for_each_gfn_sp(a, c, d) S | - for_each_gfn_indirect_valid_sp(a, c, d, b) S + for_each_gfn_indirect_valid_sp(a, c, d) S | for_each_host(a, - b, c) S | for_each_host_safe(a, - b, c, d) S | for_each_mesh_entry(a, - b, c, d) S ) ...+> [akpm@linux-foundation.org: drop bogus change from net/ipv4/raw.c] [akpm@linux-foundation.org: drop bogus hunk from net/ipv6/raw.c] [akpm@linux-foundation.org: checkpatch fixes] [akpm@linux-foundation.org: fix warnings] [akpm@linux-foudnation.org: redo intrusive kvm changes] Tested-by: Peter Senna Tschudin <peter.senna@gmail.com> Acked-by: Paul E.

staging: binder: Support concurrent 32 bit and 64 bit processes. For 64bit systems we want to use the same binder interface for 32bit and 64bit processes. Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes. This change replaces all the uses of void* and size_t with binder_uintptr_t and binder_size_t. These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace. This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for compatability, which if set which enables the old protocol, setting BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems. Please note that all 64bit kernels will use the 64bit Binder ABI.

hlist: drop the node parameter from iterators I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually. The semantic patch which is mostly the work of Peter Senna Tschudin is here: @@ iterator name hlist_for_each_entry, hlist_for_each_entry_continue, hlist_for_each_entry_from, hlist_for_each_entry_rcu, hlist_for_each_entry_rcu_bh, hlist_for_each_entry_continue_rcu_bh, for_each_busy_worker, ax25_uid_for_each, ax25_for_each, inet_bind_bucket_for_each, sctp_for_each_hentry, sk_for_each, sk_for_each_rcu, sk_for_each_from, sk_for_each_safe, sk_for_each_bound, hlist_for_each_entry_safe, hlist_for_each_entry_continue_rcu, nr_neigh_for_each, nr_neigh_for_each_safe, nr_node_for_each, nr_node_for_each_safe, for_each_gfn_indirect_valid_sp, for_each_gfn_sp, for_each_host; type T; expression a,c,d,e; identifier b; statement S; @@ -T b; <+... when != b ( hlist_for_each_entry(a, - b, c, d) S | hlist_for_each_entry_continue(a, - b, c) S | hlist_for_each_entry_from(a, - b, c) S | hlist_for_each_entry_rcu(a, - b, c, d) S | hlist_for_each_entry_rcu_bh(a, - b, c, d) S | hlist_for_each_entry_continue_rcu_bh(a, - b, c) S | for_each_busy_worker(a, c, - b, d) S | ax25_uid_for_each(a, - b, c) S | ax25_for_each(a, - b, c) S | inet_bind_bucket_for_each(a, - b, c) S | sctp_for_each_hentry(a, - b, c) S | sk_for_each(a, - b, c) S | sk_for_each_rcu(a, - b, c) S | sk_for_each_from -(a, b) +(a) S + sk_for_each_from(a) S | sk_for_each_safe(a, - b, c, d) S | sk_for_each_bound(a, - b, c) S | hlist_for_each_entry_safe(a, - b, c, d, e) S | hlist_for_each_entry_continue_rcu(a, - b, c) S | nr_neigh_for_each(a, - b, c) S | nr_neigh_for_each_safe(a, - b, c, d) S | nr_node_for_each(a, - b, c) S | nr_node_for_each_safe(a, - b, c, d) S | - for_each_gfn_sp(a, c, d, b) S + for_each_gfn_sp(a, c, d) S | - for_each_gfn_indirect_valid_sp(a, c, d, b) S + for_each_gfn_indirect_valid_sp(a, c, d) S | for_each_host(a, - b, c) S | for_each_host_safe(a, - b, c, d) S | for_each_mesh_entry(a, - b, c, d) S ) ...+> [akpm@linux-foundation.org: drop bogus change from net/ipv4/raw.c] [akpm@linux-foundation.org: drop bogus hunk from net/ipv6/raw.c] [akpm@linux-foundation.org: checkpatch fixes] [akpm@linux-foundation.org: fix warnings] [akpm@linux-foudnation.org: redo intrusive kvm changes] Tested-by: Peter Senna Tschudin <peter.senna@gmail.com> Acked-by: Paul E.

hlist: drop the node parameter from iterators I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually.

staging: binder: Support concurrent 32 bit and 64 bit processes. For 64bit systems we want to use the same binder interface for 32bit and 64bit processes. Thus the size and the layout of the structures passed between the kernel and the userspace has to be the same for both 32 and 64bit processes. This change replaces all the uses of void* and size_t with binder_uintptr_t and binder_size_t. These are then typedefed to specific sizes depending on the use of the interface, as follows: * __u32 - on legacy 32bit only userspace * __u64 - on mixed 32/64bit userspace where all processes use the same interface. This change also increments the BINDER_CURRENT_PROTOCOL_VERSION to 8 and hooks the compat_ioctl entry for the mixed 32/64bit Android userspace. This patch also provides a CONFIG_ANDROID_BINDER_IPC_32BIT option for compatability, which if set which enables the old protocol, setting BINDER_CURRENT_PROTOCOL_VERSION to 7, on 32 bit systems. Please note that all 64bit kernels will use the 64bit Binder ABI.
