Howard Chu @ Symas<p>I'd been wondering why DBs weren't zero copy since at least back in 2003, working with BerkeleyDB. It's incredible how much inefficiency is built into foundational software and everyone else just blindly accepts it. We can do so much more with the hardware that we have, than most software stacks are delivering. But <a href="https://mastodon.social/tags/OpenLDAP" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OpenLDAP</span></a> and <a href="https://mastodon.social/tags/LMDB" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LMDB</span></a> have changed that... <a href="https://mastodon.social/@32e1827635450ebb3c5a7d12c1f8e7b2b514439ac10a67eef3d9fd9c5c68e245@mostr.pub/113636917233345702" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">mastodon.social/@32e1827635450</span><span class="invisible">ebb3c5a7d12c1f8e7b2b514439ac10a67eef3d9fd9c5c68e245@mostr.pub/113636917233345702</span></a></p>
Howard Chu @ Symas<p>Speaking of encrypting data at rest, I just finished up integrating <a href="https://mastodon.social/tags/LMDB" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LMDB</span></a>'s encryption support into <a href="https://mastodon.social/tags/OpenLDAP" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OpenLDAP</span></a> slapd. <a href="https://git.openldap.org/openldap/openldap/-/merge_requests/721" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">git.openldap.org/openldap/open</span><span class="invisible">ldap/-/merge_requests/721</span></a></p><p>Using libsodium's chacha20poly1305 cipher, writes are about 20% slower than without encryption. Reads are a bit slower still. OpenSSL's chacha20poly1305 is a bit faster than libsodium's, though I only measured these in single-threaded workloads. Not sure if OpenSSL's internal locking affects multithreaded workloads here.</p>
Howard Chu @ Symas<p>After something like 30 years hacking with <a href="https://mastodon.social/tags/OpenSSL" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OpenSSL</span></a>, I think it's time to part ways. The <a href="https://mastodon.social/tags/OpenLDAP" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OpenLDAP</span></a> Project will be deprecating OpenSSL support and recommending some other crypto library in the near future. <a href="https://github.com/openssl/openssl/issues/25294#issuecomment-2391707060" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">github.com/openssl/openssl/iss</span><span class="invisible">ues/25294#issuecomment-2391707060</span></a></p><p>Who knew that "libraries shouldn't require their callers to leak memory" would be a controversial position?</p>
Howard Chu @ Symas<p>Quick reminder - any docs you've found for <a href="https://mastodon.social/tags/OpenLDAP" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OpenLDAP</span></a> online anywhere besides openldap.org were probably written by people who have no idea what they're talking about.</p><p>Stop using web search to find information that's already included in the official docs bundled with the release and already installed on your local machine.
