These programs employ a socket in /tmp. This makes it easy to compile
|
||
|
|
and run the programs. However, for a security reasons, a real-world
|
||
|
|
application should never create sensitive files in /tmp. (As a simple of
|
||
|
|
example of the kind of security problems that can result, a malicious
|
||
|
|
user could create a file using the name defined in SV_SOCK_PATH, and
|
||
|
|
thereby cause a denial of service attack against this application.
|
||
|
|
See Section 38.7 of "The Linux Programming Interface" for more details
|
||
|
|
on this subject.)
