Yu Watanabe	ae45e1a383	resolve: slightly optimize dns_answer_add() ... Previously, dns_answer_add() was O(n^2). With this change dns_packet_extract() becomes ~15 times faster for some extremal case. Before: ``` $ time ./fuzz-dns-packet ~/downloads/clusterfuzz-testcase-minimized-fuzz-dns-packet-5631106733047808 /home/watanabe/downloads/clusterfuzz-testcase-minimized-fuzz-dns-packet-5631106733047808... ok real 0m15.453s user 0m15.430s sys 0m0.007s ``` After: ``` $ time ./fuzz-dns-packet ~/downloads/clusterfuzz-testcase-minimized-fuzz-dns-packet-5631106733047808 /home/watanabe/downloads/clusterfuzz-testcase-minimized-fuzz-dns-packet-5631106733047808... ok real 0m0.831s user 0m0.824s sys 0m0.006s ``` Hopefully fixes oss-fuzz#19227. https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=19227	2020-12-30 04:14:22 +09:00

Zbigniew Jędrzejewski-Szmek	c74a3f973e	fuzz: unify the "fuzz-regressions" directory with the main corpus ... There isn't really much need to keep them separate. Anything which is a good corpus entry can be used as a smoke test, and anything which which is a regression test can just as well be inserted into the corpus. The only functional difference from this patch (apart from different paths in output) is that the regression tests are now zipped together with the rest of the corpus. $ meson configure build -Dslow-tests=true && ninja -C build test ... 307/325 fuzz-dns-packet:issue-7888:address OK 0.06 s 308/325 fuzz-dns-packet:oss-fuzz-5465:address OK 0.04 s 309/325 fuzz-journal-remote:crash-5a8f03d4c3a46fcded39527084f437e8e4b54b76:address OK 0.07 s 310/325 fuzz-journal-remote:crash-96dee870ea66d03e89ac321eee28ea63a9b9aa45:address OK 0.05 s 311/325 fuzz-journal-remote:oss-fuzz-8659:address OK 0.05 s 312/325 fuzz-journal-remote:oss-fuzz-8686:address OK 0.07 s 313/325 fuzz-unit-file:oss-fuzz-6884:address OK 0.06 s 314/325 fuzz-unit-file:oss-fuzz-6885:address OK 0.05 s 315/325 fuzz-unit-file:oss-fuzz-6886:address OK 0.05 s 316/325 fuzz-unit-file:oss-fuzz-6892:address OK 0.05 s 317/325 fuzz-unit-file:oss-fuzz-6897:address OK 0.05 s 318/325 fuzz-unit-file:oss-fuzz-6897-evverx:address OK 0.06 s 319/325 fuzz-unit-file:oss-fuzz-6908:address OK 0.07 s 320/325 fuzz-unit-file:oss-fuzz-6917:address OK 0.07 s 321/325 fuzz-unit-file:oss-fuzz-6977:address OK 0.13 s 322/325 fuzz-unit-file:oss-fuzz-6977-unminimized:address OK 0.12 s 323/325 fuzz-unit-file:oss-fuzz-7004:address OK 0.05 s 324/325 fuzz-unit-file:oss-fuzz-8064:address OK 0.05 s 325/325 fuzz-unit-file:oss-fuzz-8827:address OK 0.52 s	2018-10-02 09:41:25 +02:00
