* ftpd: for LIST, open current directory *in the child*Denys Vlasenko2014-06-271-3/+5
| | | | | | Last change introduced an open fd leak. This is the fix. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* ftpd: escape chroot prior to re-executing ls helperDenys Vlasenko2014-06-271-32/+21
| | | | | | | | | | | | | | | | 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. As a bonus, this gives us proper usernames, timezone conversion etc. function old new delta popen_ls 203 259 +56 ftpd_main 2362 2366 +4 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
