Package: apache2-bin Version: 2.4.46-2 Severity: important On my machine, /usr/sbin/apache2 fails to start with the following message:
[Thu Dec 24 15:38:01.052051 2020] [:crit] [pid 15725] (38)Function not implemented: AH00141: Could not initialize random number generator This happens very early, before reading conffiles or parsing command-line arguments. The error comes from line 5674 here: https://svn.apache.org/viewvc/httpd/httpd/trunk/server/core.c?revision=1884431&view=markup#l5674 and is due to a failure in apr_generate_random_bytes(). You can see that the associated call/failure is happening inside APR here, on line 216: https://svn.apache.org/viewvc/apr/apr/trunk/misc/unix/rand.c?revision=1832691&view=markup#l216 The issue is that if the library is configured (at build time) to USE_GETRANDOM, then it assumes that the getrandom() call will be available and if it fails it becomes a fatal error. On my system, I don't have getrandom() because I'm running an ancient kernel, but others could (more legitimately) have the option disabled on a recent custom-built kernel. I think the correct fix is to not use that build-time option, and go back to using DEV_RANDOM or whatever was being used previously. Alternatively, at least document that a kernel with getrandom() support is required to use apache2. I'm not sure exactly when the packaging on this changed, but I know it was broken in 2.4.46-1 and I *think* it worked in 2.4.43-1, although I can't get a copy of that to double-check anymore. -- Package-specific info: -- System Information: Debian Release: bullseye/sid APT prefers testing APT policy: (501, 'testing'), (100, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.14.15 (SMP w/4 CPU threads) Locale: LANG=C, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages apache2-bin depends on: ii libapr1 1.7.0-4 ii libaprutil1 1.6.1-5 ii libaprutil1-dbd-sqlite3 1.6.1-5 ii libaprutil1-ldap 1.6.1-5 ii libbrotli1 1.0.9-2+b2 ii libc6 2.31-5 ii libcrypt1 1:4.4.17-1 ii libcurl4 7.72.0-1 ii libjansson4 2.13.1-1 ii libldap-2.4-2 2.4.56+dfsg-1 ii liblua5.2-0 5.2.4-1.1+b3 ii libnghttp2-14 1.42.0-1 ii libpcre3 2:8.39-13 ii libssl1.1 1.1.1h-1 ii libxml2 2.9.10+dfsg-6.3+b1 ii perl 5.32.0-6 ii zlib1g 1:1.2.11.dfsg-2 apache2-bin recommends no packages.
