2018-07-06qemu: decide debug kernel based on KERNEL_VERSIONJason A. Donenfeld
If KERNEL_VERSION ends in -debug, then automatically set DEBUG_KERNEL If DEBUG_KERNEL is set, now the debug kernel will be built in a separate directory from the normal kernel, so that it's easy to toggle back and forth. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-07-06qemu: bump default kernel versionJason A. Donenfeld
This fixes DEBUG_KERNEL=yes due to dd275caf4a0d9b219fffe49288b6cc33cd564312 being backported to 4.17.4. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-04-15send: account for route-based MTUJason A. Donenfeld
It might be that a particular route has a different MTU than the interface, via `ip route add ... dev wg0 mtu 1281`, for example. In this case, it's important that we don't accidently pad beyond the end of the MTU. We accomplish that in this patch by carrying forward the MTU from the dst if it exists. We also add a unit test for this issue. Reported-by: Roman Mamedov <rm.wg@romanrm.net> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-02-01curve25519: replace fiat64 with faster hacl64Jason A. Donenfeld
This reverts commit da4ff396cc5d5e0ff21f9ecbc2f951c048c63fff and adds some optimizations to hacl64. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-02-01curve25519: replace hacl64 with fiat64Jason A. Donenfeld
For now, it's faster: hacl64: 109782 cycles per call fiat64: 108984 cycles per call It's quite possible this commit will be reverted with nice changes from INRIA, though. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-01-23qemu: disable AVX-512 in userlandJason A. Donenfeld
We're trying to test kernel code, so the userland tools we use for doing that testing don't really matter to us. We turn off AVX512, because WireGuard supports kernels that do not support AVX512 userlands. It's easier to just blanket-disable it all, since it doesn't matter anyway. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-01-23qemu: disable PIE for compilationJason A. Donenfeld
Some old kernels never backported this fix to the build system, and it's required if we want to build those old kernels with PIE-by-default compilers. 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.

2017-11-17qemu: use unprefixed strip when not cross-compilingJason A. Donenfeld
Fedora/Redhat doesn't ship with a prefixed strip, and we don't need to use it anyway when we're not cross compiling, so don't. Reported-by: Samuel Neves <sneves@dei.uc.pt> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-11-10netlink: make sure we reserve space for NLMSG_DONEJason A. Donenfeld
Otherwise, if messages pack really close together, we'll exceed the size of the sk_buff and return ENOBUFS. I suspect this has been the cause of a lot of weird bugs that people just worked around by increasing the receive buffer size. This actually addresses the root cause. Signed-off-by: Jason A.

2017-10-31netns: use read built-in instead of ncat hack for dmesgJason A. Donenfeld
This misses lines that are greater than 128 bytes -- read returns -EINVAL -- but the lines we care about anyway are less than that, so we simply keep looping and skip the bad reads when this happens. Not ideal, but probably the best we can do in pure bash. And, importantly, it's much better than streaming this over a TCP socket, which was an even uglier hack. Signed-off-by: Jason A.
