Hi All, Recent discussion raised by Andrew Lunn and others regarding default permission set on the nvmem binary sysfs file resulted in this small fixup patchset. By default nvmem core sets the readonly permission to everyone (S_IRUGO), this is not desirable by many providers as they would not want everyone to view things like passwords stored in the nvmem. This patchset fixes this by making the default as root-only and then the providers could supply with additional permissions if required. One of the patch in this set also sets correct size for the binary file too, so that the user would not even attempt to read past the size. I have tested this on IFC6410 with qfprom. Thanks, srini Srinivas Kandagatla (3): nvmem: make default user binary file root-access only nvmem: set the size for the nvmem binary file. nvmem: add permission flags in nvmem_config drivers/nvmem/core.c | 55 +++++++++--------------------------------- include/linux/nvmem-provider.h | 1 + 2 files changed, 13 insertions(+), 43 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
