[tor/maint-0.3.2] In the hsdescv3 fuzzer, replace the decryption function.

commit 26e0909e516a91281c2ad1fcac23405f3cc1ee11 Author: Nick Mathewson <nickm(a)torproject.org> Date: Fri Oct 27 14:28:02 2017 -0400 In the hsdescv3 fuzzer, replace the decryption function. The new decryption function performs no decryption, skips the salt, and doesn't check the mac. This allows us to fuzz the hs_descriptor.c code using unencrypted descriptor test, and exercise more of the code. Related to 21509. --- changes/hsdescv3_fuzz_more | 3 +++ src/or/hs_descriptor.c | 12 ++++++------ src/or/hs_descriptor.h | 7 +++++++ src/test/fuzz/fuzz_hsdescv3.c | 19 +++++++++++++++++++ 4 files changed, 35 insertions(+), 6 deletions(-) diff --git a/changes/hsdescv3_fuzz_more b/changes/hsdescv3_fuzz_more new file mode 100644 index 000000000..25626bb9a --- /dev/null +++ b/changes/hsdescv3_fuzz_more @@ -0,0 +1,3 @@ + o Minor features (testing): + - Our fuzzing tests now test the encrypted portions of the + v3 hidden service descriptors.
