#2593 closed defect (duplicate)

Stream proxy ptotocol header is not valid

Reported by: zdm@… Owned by:
Priority: minor Milestone:
Component: documentation Version: 1.25.x
Keywords: Cc:
uname -a:
nginx -V: p.25.3


Nginx sends proxy protocol header without triling "\r\n" when unix socket path is too long,

Sample config:

strema {

server {

listen *.80;
proxy_pass unix:/var/run/1.socket;
proxy_protocol on;


server {

listen unix:/var/run/1.socket prtoxy_protocol;
proxy_protocol on;




When send simple HTTP GET request to :80 - it;s ok;

But when socket oath is ontr, than 80 chars - nginx sends data like this ( WITHOUT "\r\n" separator after proxy protocol header ):

PROXY TCP unix:.... pott1 port2GET
