[PATCH] staging: greybus: add missing newlines to sysfs_emit() output

by Yousef Alhouseen

Sysfs show() callbacks should emit a trailing newline for text output. Several Greybus audio manager module attributes currently omit the newline, which triggers checkpatch warnings and makes the attributes less convenient to read from userspace. Append missing newlines to the affected sysfs_emit() format strings.

[PATCH v1] greybus: authentication: validate CAP response payload size

by Muhammad Bilal

cap_get_ims_certificate() and cap_authenticate() copy variable-length response data directly into fixed-size UAPI buffers using the untrusted op->response->payload_size value without any bounds checks. A malicious or compromised Greybus endpoint can return an oversized certificate or signature payload, causing a kernel heap overflow. Fix both functions by: - Rejecting responses shorter than sizeof(*response) with -EPROTO. - Rejecting payloads exceeding CAP_CERTIFICATE_MAX_SIZE (1600) or CAP_SIGNATURE_MAX_SIZE (320) with -EMSGSIZE. - Copying only the validated size into the UAPI buffer.
