Fix -Wformat-truncated warnings to complete the intel directories' W=1 clean efforts. The W=1 recently got enhanced with a few new flags and this brought up some new warnings. Switch to using kasprintf() when possible so we always allocate the right length strings. summary of warnings: drivers/net/ethernet/intel/iavf/iavf_virtchnl.c:1425:60: warning: ‘%s’ directive output may be truncated writing 4 bytes into a region of size between 1 and 11 [-Wformat-truncation=] drivers/net/ethernet/intel/iavf/iavf_virtchnl.c:1425:17: note: ‘snprintf’ output between 7 and 17 bytes into a destination of size 13 drivers/net/ethernet/intel/ice/ice_ptp.c:43:27: warning: ‘%s’ directive output may be truncated writing up to 479 bytes into a region of size 64 [-Wformat-truncation=] drivers/net/ethernet/intel/ice/ice_ptp.c:42:17: note: ‘snprintf’ output between 1 and 480 bytes into a destination of size 64 drivers/net/ethernet/intel/igb/igb_main.c:3092:53: warning: ‘%d’ directive output may be truncated writing between 1 and 5 bytes into a region of size between 1 and 13 [-Wformat-truncation=] drivers/net/ethernet/intel/igb/igb_main.c:3092:34: note: directive argument in the range [0, 65535] drivers/net/ethernet/intel/igb/igb_main.c:3092:34: note: directive argument in the range [0, 65535] drivers/net/ethernet/intel/igb/igb_main.c:3090:25: note: ‘snprintf’ output between 23 and 43 bytes into a destination of size 32 Suggested-by: Alexander Lobakin <aleksander.lobakin@intel.com> Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Tested-by: Pucha Himasekhar Reddy <himasekharx.reddy.pucha@intel.com> (A Contingent worker at Intel) Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Link: https://lore.kernel.org/r/20231017190411.2199743-2-jacob.e.keller@intel.com 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.
