Question about changing EnableSendfile to On?

[odunybrad]

Thanks for providing the container! I am doing a research aiming at finding issues in configuration files. After pulling the image we notice that EnableSendfile is set to on in /etc/httpd/conf/httpd.conf, whose default is Off.

However, the HttpD official document recommends to set EnableSendfile to Off to avoid operational problems when:

• Some platforms may have broken sendfile support that the build system did not detect, especially if the binaries were built on another box and moved to such a machine with broken sendfile support.
• On Linux the use of sendfile triggers TCP-checksum offloading bugs on certain networking cards when using IPv6.
• On Linux on Itanium, sendfile may be unable to handle files over 2GB in size.
• With a network-mounted DocumentRoot (e.g., NFS, SMB, CIFS, FUSE), the kernel may be unable to serve the network file through its own cache.

Shall we set EnableSendfile back to off as default?

This is the default value of EnableSendfile in our distribution of httpd (specifically this one http://mirror.centos.org/centos/7/os/x86_64/Packages/httpd-2.4.6-90.el7.centos.x86_64.rpm) so I'd like to not change it given that we are not currently overriding it.

Also I think this was just a bot account that went around spamming repos a while back. Not exactly a helpful issue.
