[Solved] lighttpd cannot start after upgrade from 1.4.74 to 1.4.75

Hi,

I upgraded lighttpd to latest version 1.4.75 and now I'm getting:

/usr/sbin/lighttpd: symbol 'mod_openssl_asn1_time_to_posix': can't resolve symbol in lib '/usr/lib/lighttpd/mod_openssl.so'.
2024-03-27 17:24:08: (plugin.c.221) dlopen() failed for: /usr/lib/lighttpd/mod_openssl.so Unable to resolve symbol
2024-03-27 17:24:08: (server.c.1649) loading plugins finally failed

/usr/lib/lighttpd/mod_openssl.so wants to import symbol mod_openssl_asn1_time_to_posix but nothing provides it.

So I rebuilt it and there was a warning:

libtool: link: ( cd ".libs" && rm -f "mod_openssl.la" && ln -s "../mod_openssl.la" "mod_openssl.la" )

So it looks like mod_openssl.c declares mod_openssl_asn1_time_to_posix but doesn't define it, what causes gcc to try to import that symbol. In runtime the symbol is missing so mod_openssl.so cannot be loaded and lighttpd dies due to missing plugin.
I have OpenSSL 3.2.1 and OPENSSL_NO_OCSP defined.
When I reverted just this change:
https://redmine.lighttpd.net/projects/lighttpd/repository/14/diff/src/mod_openssl.c?utf8=%E2%9C%93&rev=7adc0f65fb0459b33b75e2af57b41d27e4853925&rev_to=87b3a9cab8d964330aef12db9f78aae66eaf0968
lighttpd started properly and seems to be working.

You are correct that mod_openssl_asn1_time_to_posix is not defined when OPENSSL_NO_OCSP is defined, but needs to be for changes made in lighttpd 1.4.75.

Commit 7adc0f65f message explains why the change was made in lighttpd 1.4.75.

The following patch should fix that for you.
