2018-09-23allowedips: work around kasan stack frame bug in selftestJason A. Donenfeld
Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-20global: put SPDX identifier on its own lineJason A. Donenfeld
The kernel has very specific rules correlating file type with comment type, and also SPDX identifiers can't be merged with other comments. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-20ratelimiter: disable selftest with KASANJason A. Donenfeld
This this relies on instructions taking a "normal" amount of time, we really can't run this with KASAN, especially inside QEMU, so just disable it for KASAN, since it's hard to make it complete on slow systems. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-20allowedips: change from BUG_ON to WARN_ONJason A. Donenfeld
This is never going to hit anyway, and if it does, it's a development problem that will be caught with the selftests anyway. So don't make Andrew Lunn upset, and just change it to a WARN_ON. Suggested-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-08-28crypto: use unaligned helpersJason A. Donenfeld
This is not useful for WireGuard, but for the general use case we probably want it this way, and the speed difference is mostly lost in the noise. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-08-28global: run through clang-formatJason A. Donenfeld
This is the worst commit in the whole repo, making the code much less readable, but so it goes with upstream maintainers. We are now woefully wrapped at 80 columns. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-05-14allowedips: Fix graphviz output after endianness patchJonathan Neuschäfer
Commit 5e3532e ("allowedips: use native endian on lookup") did two things: It changed the endianness of (struct allowedips_node).bits to native endian, and it moved the CIDR masking to the output code path (walk_by_peer). Adjust print_node in src/selftest/allowedips.h to deal with these changes. Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

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.

2017-10-31global: infuriating kernel iterator styleJason A. Donenfeld
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. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-04-21routingtable: rewrite core functionsJason A. Donenfeld
When removing by peer, prev needs to be set to *nptr in order to traverse that part of the trie. The other remove by IP function can simply be removed, as it's not in use. The root freeing function can use pre-order traversal instead of post-order. The pre-order traversal code in general is now a nice iterator macro. The common bits function can use the fast fls instructions and the match function can be rewritten to simply compare common bits. While we're at it, let's add tons of new tests, randomized checking against a dumb implementation, and graphviz output. And in general, it's nice to clean things up. Signed-off-by: Jason A.
