2019-10-17rpmsg: glink: Free pending deferred work on removeBjorn Andersson1-1/+13
By just cancelling the deferred rx worker during GLINK instance teardown any pending deferred commands are leaked, so free them.

2019-10-17rpmsg: glink: Don't send pending rx_done during removeBjorn Andersson1-3/+12
Attempting to transmit rx_done messages after the GLINK instance is being torn down will cause use after free and memory leaks. So cancel the intent_work and free up the pending intents. With this there are no concurrent accessors of the channel left during qcom_glink_native_remove() and there is therefor no need to hold the spinlock during this operation - which would prohibit the use of cancel_work_sync() in the release function. So remove this.

2019-10-16rpmsg: glink: Fix rpmsg_register_device err handlingChris Lew1-3/+1
The device release function is set before registering with rpmsg. If rpmsg registration fails, the framework will call device_put(), which invokes the release function. The channel create logic does not need to free rpdev if rpmsg_register_device() fails and release is called.

2019-08-29rpmsg: glink: Use struct_size() helperGustavo A. R. Silva1-1/+1
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct { ... struct intent_pair intents[]; } __packed * msg; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(*msg) + sizeof(struct intent_pair) * count with: struct_size(msg, intents, count) This code was detected with the help of Coccinelle. Signed-off-by: Gustavo A.

Intents are nothing but pre-allocated buffers of appropriate size that are allocated on the local side and communicated to the remote side and the remote stores the list of intent ids that it is informed. Later when remote side is intenting to send data, it picks up a right intent (based on the size) and sends the data buffer and the intent id. Local side receives the data and copies it to the local intent buffer. The whole idea is to avoid stalls on the transport for allocating memory, used for copy based transports. When the remote request to allocate buffers using CMD_RX_INTENT_REQ, we allocate buffers of requested size, store the buffer id locally and also communicate the intent id to the remote.
