* global: put SPDX identifier on its own lineJason A. Donenfeld2018-09-201-2/+2
| | | | | The kernel has very specific rules correlating file type with comment type, and also SPDX identifiers can't be merged with other comments.

* global: add SPDX tags to all filesGreg Kroah-Hartman2017-12-091-1/+4
| | | | | | | | | | | | | It's good to have SPDX identifiers in all files as the Linux kernel developers are working to add these identifiers to all files. Update all files with the correct SPDX license identifier based on the license text of the project or based on the license in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Modified-by: Jason A. Donenfeld <Jason@zx2c4.com>

* global: infuriating kernel iterator styleJason A. Donenfeld2017-10-311-2/+2
| | | | | | | | | | | | | | | | | One types: for (i = 0 ... So one should also type: for_each_obj (obj ... But the upstream kernel style guidelines are insane, and so we must instead do: for_each_obj(obj ... Ugly, but one must choose his battles wisely.

* tools: use key_is_zero for comparing to zerosJason A. Donenfeld2017-09-241-3/+2
| | | | | | | Maybe an attacker on the system could use the infoleak in /proc to gauge how long a wg(8) process takes to complete and determine the number of leading zeros. This is somewhat ridiculous, but it's possible somebody somewhere might at somepoint care in the future, so alright.
