Dear all, Wishing you a good day. My day could have been better, I've been battling a problem with mod_fcgid in combination with ModSecurity's SecChrootDir feature, which chroots the webserver into /chroot/apache. The virtualhosts live under this and it's a nice feature.
As soon as I enable mod_fcgid, Apache fails to start with the following error message: [fcgid:emerg] [pid 5344] (38)Function not implemented: mod_fcgid: Can't create shared memory for size 1200712 bytes My OS is Ubuntu 20.04 LTS. I've tried: * ensuring /chroot/apache/var/run/fcgid_shm and fcgidsock exist with mode 1777 * creating /chroot/apache/dev/shm with mode 1777 * using 'strace apache2ctl start' to see what syscall is being attempted, and hacking the apachectl script to start Apache directly even in the presence of $need_systemd so that it runs Apache directly - still I don't get any useful information from this * The error disappears whenever I disable the chroot functionality, but for security reasons I'd really like to keep the chroot enabled. Can anyone give me a hint to further debug this problem? Kind regards, Robbie
