gcc reports that the temporary buffer for computing the
string length may be too small here:
drivers/net/ethernet/cavium/liquidio/lio_ethtool.c: In function 'lio_get_eeprom_len':
/drivers/net/ethernet/cavium/liquidio/lio_ethtool.c:345:21: error: 'sprintf' may write a terminating nul past the end of the destination [-Werror=format-overflow=]
len = sprintf(buf, "boardname:%s serialnum:%s maj:%lld min:%lld\n",
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/ethernet/cavium/liquidio/lio_ethtool.c:345:6: note: 'sprintf' output between 35 and 167 bytes into a destination of size 128
len = sprintf(buf, "boardname:%s serialnum:%s maj:%lld min:%lld\n",
This extends it to 192 bytes, which is certainly enough. As far
as I could tell, there are no other constraints that require a specific
maximum size.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
