After gaining __alloc_size hints, GCC thinks it can reach a memcpy() with eir_len == 0 (since it can't see into the rewrite of status). Instead, check eir_len == 0, avoiding this future warning: In function 'eir_append_data', inlined from 'read_local_oob_ext_data_complete' at net/bluetooth/mgmt.c:7210:12: ./include/linux/fortify-string.h:54:29: warning: '__builtin_memcpy' offset 5 is out of the bounds [0, 3] [-Warray-bounds] ... net/bluetooth/hci_request.h:133:2: note: in expansion of macro 'memcpy' 133 | memcpy(&eir[eir_len], data, data_len); | ^~~~~~ Cc: Marcel Holtmann <marcel@holtmann.org> Cc: Johan Hedberg <johan.hedberg@gmail.com> Cc: Luiz Augusto von Dentz <luiz.dentz@gmail.com> Cc: "David S.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
