4. EFI_VARIABLE_APPEND_WRITE with EFI_OUT_OF_RESOURCES truncates size but you can still read its content.I'm not sure what you mean by this. Could you please explain?
Oops, this one is incorrect. I was testing EFI_VARIABLE_APPEND_WRITE using this: printf "\x47\x00\x00\x00\x00" >test-1-$guid So it truncates the file before writing, but efivarfs figures out the right size afterwards. The size remains zero if the write fails. I should be using this for appending: printf "\x47\x00\x00\x00\x00" >>test-1-$guid -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
