net: bridge: fix ioctl old_deviceless bridge argument
Commit 561d8352818f ("bridge: use ndo_siocdevprivate") changed the source and destination arguments of copy_{to,from}_user in bridge's old_deviceless() from args[1] to uarg breaking SIOC{G,S}IFBR ioctls. Commit cbd7ad29a507 ("net: bridge: fix ioctl old_deviceless bridge argument") fixed only BRCTL_{ADD,DEL}_BRIDGES commands leaving BRCTL_GET_BRIDGES one untouched. The fixes BRCTL_GET_BRIDGES as well and has been tested with busybox's brctl. Example of broken brctl: $ brctl show bridge name bridge id STP enabled interfaces brctl: can't get bridge name for index 0: No such device or address Example of fixed brctl: $ brctl show bridge name bridge id STP enabled interfaces br0 8000.000000000000 no Fixes: 561d8352818f ("bridge: use ndo_siocdevprivate") Signed-off-by: Remi Pommarel <repk@triplefau.lt> Reviewed-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Nikolay Aleksandrov <nikolay@nvidia.com> Link: https://lore.kernel.org/all/20211223153139.7661-2-repk@triplefau.lt/ Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
