2017-01-24ftpd: new option -a ANON_USER to allow anonymous loginsAndrey Mozzhuhin
Anonymous ftpd login is useful even when ftpd authentication feature is enabled. Anonymous logins provide simple password-less connection for FTP clients. To allow password-less connection user command line option '-a USER' is added. This option specifies the system user to use when 'anonymous' username is given in USER command. No password is required in this case. function old new delta ftpd_main 2164 2232 +68 packed_usage 31015 31046 +31 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 99/0) Total: 99 bytes Signed-off-by: Andrey Mozzhuhin <amozzhuhin@yandex.ru> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2015-10-13ftpd: make DIR parameter work for non-root too: chdir to it instead of chrootDenys Vlasenko
Unfortunately, chroot() works only for root user, because of attacks on setuid binaries (make DIR/lib/ld-linux.so a shell, hardlink to a setuid binary, chroot to DIR, execute it and get root shell). function old new delta ftpd_main 2160 2180 +20 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2014-06-27ftpd: escape chroot prior to re-executing ls helperDenys Vlasenko
When we merely chdir to saved "real" root fd, exec("proc/self/exe") works for static executables but not for dynamic ones (they can't find their interpreter). With this patch, we also *chroot* to real root.
