From d1b75e1842b3e4f61daae2fb8a64d784a553f15c Mon Sep 17 00:00:00 2001 From: Ron Yorston Date: Tue, 7 Apr 2020 10:41:34 +0100 Subject: [PATCH] httpd: permit non-default home directory with NOMMU enabled When BusyBox is compiled with NOMMU enabled running httpd with the '-h' option fails even if the specified directory exists: $ ls -d www www $ busybox httpd -fvvvp 8080 -h www ... ... try to access http://localhost:8080/www ... httpd: can't change directory to 'www': No such file or directory The parent process executes xchdir("www"). When a connection is accepted it's handled by re-executing httpd in inetd mode. The child process inherits the current directory "www" and tries to change directory again to "www", which fails. Omit the call to xchdir() when httpd is re-executed.
