2021-06-02kbuild: do not use -O3Jason A. Donenfeld
Apparently, various versions of gcc have O3-related miscompiles. Looking at the difference between -O2 and -O3 for gcc 11 doesn't indicate miscompiles, but the difference also doesn't seem so significant for performance that it's worth risking.

2020-06-18Kbuild: remove -fvisibility=hidden from cflagsJason A. Donenfeld
This was originally done in 2015 as a means of decreasing module size, but it has the effect of creating JUMP11 relocations on ARM when compiled in THUMB2 mode without CONFIG_THUMB2_AVOID_R_ARM_THM_JUMP11=y, which results in `B ...` instructions being generated with jumps that are too far, rather than `B.W ...` instructions, which can handle the larger sized jump. Get rid of the old hack, which had minimum utility anyway. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2020-01-11Makefile: strip prefixed v from version.hJason A. Donenfeld
We also no longer do anything dynamic with dkms.conf, and we don't rewrite any files at all, but rather pass this through as a cflag to the compiler optionally. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> Reported-by: Egbert Verhage <egbert@eggiecode.org>

2017-12-09global: add SPDX tags to all filesGreg Kroah-Hartman
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.

2017-09-18queue: entirely rework parallel systemJason A. Donenfeld
This removes our dependency on padata and moves to a different mode of multiprocessing that is more efficient. This began as Samuel Holland's GSoC project and was gradually reworked/redesigned/rebased into this present commit, which is a combination of his initial contribution and my subsequent rewriting and redesigning.

This not only removes the depenency on x_tables, but it also gives us much better performance and memory usage. Now, systems are able to have millions of WireGuard interfaces, without having to worry about a thundering herd of garbage collection. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
