2018-09-14binder: Add BINDER_GET_NODE_INFO_FOR_REF ioctl.Martijn Coenen
This allows the context manager to retrieve information about nodes that it holds a reference to, such as the current number of references to those nodes. Such information can for example be used to determine whether the servicemanager is the only process holding a reference to a node. This information can then be passed on to the process holding the node, which can in turn decide whether it wants to shut down to reduce resource usage.

2018-09-14binder: use standard functions to allocate fdsTodd Kjos
Binder uses internal fs interfaces to allocate and install fds: __alloc_fd __fd_install __close_fd get_files_struct put_files_struct These were used to support the passing of fds between processes as part of a transaction. The actual allocation and installation of the fds in the target process was handled by the sending process so the standard functions, alloc_fd() and fd_install() which assume task==current couldn't be used. This patch refactors this mechanism so that the fds are allocated and installed by the target process allowing the standard functions to be used. The sender now creates a list of fd fixups that contains the struct *file and the address to fixup with the new fd once it is allocated. This list is processed by the target process when the transaction is dequeued. A new error case is introduced by this change. If an async transaction with file descriptors cannot allocate new fds in the target (probably due to out of file descriptors), the transaction is discarded with a log message. In the old implementation this would have been detected in the sender context and failed prior to sending.

2018-09-14android: binder: no outgoing transaction when thread todo has transactionSherry Yang
When a process dies, failed reply is sent to the sender of any transaction queued on a dead thread's todo list. The sender asserts that the received failed reply corresponds to the head of the transaction stack. This assert can fail if the dead thread is allowed to send outgoing transactions when there is already a transaction on its todo list, because this new transaction can end up on the transaction stack of the original sender. The following steps illustrate how this assertion can fail. 1. Thread1 sends txn19 to Thread2 (T1->transaction_stack=txn19, T2->todo+=txn19) 2. Without processing todo list, Thread2 sends txn20 to Thread1 (T1->todo+=txn20, T2->transaction_stack=txn20) 3. T1 processes txn20 on its todo list (T1->transaction_stack=txn20->txn19, T1->todo=<empty>) 4. T2 dies, T2->todo cleanup attempts to send failed reply for txn19, but T1->transaction_stack points to txn20 -- assertion failes Step 2. is the incorrect behavior. When there is a transaction on a thread's todo list, this thread should not be able to send any outgoing synchronous transactions. Only the head of the todo list needs to be checked because only threads that are waiting for proc work can directly receive work from another thread, and no work is allowed to be queued on such a thread without waking up the thread. This patch also enforces that a thread is not waiting for proc work when a work is directly enqueued to its todo list.

2018-09-12uio: ensure class is registered before devicesAlexandre Belloni
When both uio and the uio drivers are built in the kernel, it is possible for a driver to register devices before the uio class is registered. This may result in a NULL pointer dereference later on in get_device_parent() when accessing the class glue_dirs spinlock. The trace looks like that: Unable to handle kernel NULL pointer dereference at virtual address 00000140 [...] [<ffff0000089cc234>] _raw_spin_lock+0x14/0x48 [<ffff0000084f56bc>] device_add+0x154/0x6a0 [<ffff0000084f5e48>] device_create_groups_vargs+0x120/0x128 [<ffff0000084f5edc>] device_create+0x54/0x60 [<ffff0000086e72c0>] __uio_register_device+0x120/0x4a8 [<ffff000008528b7c>] jaguar2_pci_probe+0x2d4/0x558 [<ffff0000083fc18c>] local_pci_probe+0x3c/0xb8 [<ffff0000083fd81c>] pci_device_probe+0x11c/0x180 [<ffff0000084f88bc>] driver_probe_device+0x22c/0x2d8 [<ffff0000084f8a24>] __driver_attach+0xbc/0xc0 [<ffff0000084f69fc>] bus_for_each_dev+0x4c/0x98 [<ffff0000084f81b8>] driver_attach+0x20/0x28 [<ffff0000084f7d08>] bus_add_driver+0x1b8/0x228 [<ffff0000084f93c0>] driver_register+0x60/0xf8 [<ffff0000083fb918>] __pci_register_driver+0x40/0x48 Return EPROBE_DEFER in that case so the driver can register the device later.

If there is no System.map file for "make modules_install", scripts/depmod.sh will silently exit with success, having done nothing. Since this is an unexpected situation, change it to report a Warning for the missing file. The behavior is not changed except for the Warning message. The (previous) silent success and new Warning can be reproduced by: $ make mrproper; make defconfig $ make modules; make modules_install and since System.map is produced by "make vmlinux", the steps above omit producing the System.map file.
