tag_insight = "The sendfile(2) system call allows a server application (such as a
HTTP or FTP server) to transmit the contents of a file over a network
connection without first copying it to application memory.  High
performance servers such as the Apache HTTP Server and ftpd use sendfile.

When a process opens a file (and other file system objects, such as
directories), it specifies access flags indicating its intent to read,
write, or perform other operations.  These flags are checked against
file system permissions, and then stored in the resulting file
descriptor to validate future operations against.

The sendfile(2) system call does not check the file descriptor access
flags before sending data from a file.";
