This set includes a number of small improvements for handling the loading of drivers at runtime using the EAL -d flag. It limits the loading of files to only those files which end in .so, which means that one can pass in the whole "drivers/" subfolder from a meson build and not get an error when DPDK trys to load a .a file. It also puts in some basic permission checking to ensure that no drivers are loaded from a world-writable location on the filesystem, which would be a potential security hole on a mis-configured system. Bruce Richardson (4): eal: remove unnecessary null-termination eal: only load shared libs from driver plugin directory eal: don't load drivers from insecure paths eal: cache last directory permissions checked lib/librte_eal/common/eal_common_options.c | 91 ++++++++++++++++++++-- 1 file changed, 83 insertions(+), 8 deletions(-)
