2024-12-02module: Convert symbol namespace to string literalPeter Zijlstra
Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

2022-07-14ASoC: SOF: ipc-msg-injector: fix copy in sof_msg_inject_ipc4_dfs_write()Dan Carpenter
There are two bugs that have to do with when we copy the payload: size = simple_write_to_buffer(ipc4_msg->data_ptr, priv->max_msg_size, ppos, buffer, count); The value of "*ppos" was supposed to be zero but it is sizeof(ipc4_msg->header_u64) so it will copy the data into the middle of the "ipc4_msg->data_ptr" buffer instead of to the start. The second problem is "buffer" should be "buffer + sizeof(ipc4_msg->header_u64)". This function is used for fuzz testing so the data is normally random and this bug likely does not affect anyone very much. In this context, it's simpler and more appropriate to use copy_from_user() instead of simple_write_to_buffer() so I have re-written the function.

2022-06-06ASoC: SOF: ipc-msg-injector: Propagate write errors correctlyDan Carpenter
This code is supposed to propagate errors from simple_write_to_buffer() or return -EFAULT if "size != count". However "size" needs to be signed for the code to work correctly and the case where "size == 0" is not handled correctly.

2022-05-17ASoC: SOF: ipc-msg-injector: Cap the rmaining to count in IPC4 modePeter Ujfalusi
If user space provides smaller buffer than the IPC4 reply then it is possible that we corrupt user space memory since the IPC4 dfs_read function is not using the count directly in copy_to_user() due to the nature of an IPC4 message. Cap the remaining counter to make sure that we are not writing too much to the user space provided buffer. Add a check also to make sure that the buffer is at least the size of the IPC4 header.

2022-05-09ASoC: SOF: ipc-msg-injector: Add support for IPC4 messagesPeter Ujfalusi
The IPC message representation of an IPC4 differs from the IPC3 version significantly. The message for IPC4 should be written to the debugfs file in this form: 0-7 IPC4 header (2x u32) 8- additional payload, if any The reply is given back in the same form. The message size limitation is the same as with the IPC3, only messages which can fit to the mailbox can be injected (and received).

2022-03-09ASoC: SOF: ipc-msg-injector: Use devm_kzalloc() for the rx_bufferPeter Ujfalusi
The rx_buffer is cleared before sending an IPC to make sure that when the /sys/kernel/debug/sof/ipc_msg_inject file is read we will have correct information in the buffer (no random or stale data). But if the user reads the file before sending any message the buffer might contain garbage which should not be interpreted. To prevent this, clear the rx_buffer on allocation.
