2014-06-27ftpd: do not use root_fd if we are not in chrootDenys Vlasenko

2014-06-27ftpd: for LIST, open current directory *in the child*Denys Vlasenko
Last change introduced an open fd leak. This is the fix. 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. 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>

2013-12-17hostname: do not use gethostbyname() for "hostname -s"Michael Tokarev
There's no reason to call gethostbyname() on the value returned by uname() when asked just for a short name of a host. This may also be wrong, when uname is set to one value, but in /etc/hosts (or elsewhere) the "canonical" name is different. This is often the case for localhost entry in /etc/hosts: 127.0.0.1 localhost myname With this content of /etc/hosts, and uname being set to myname, busybox hostname -s will return localhost, while regular hostname utility returns myname. Fix this by not calling gethostbyname() for the simple 'hostname -s' use. Signed-off-by: Michael Tokarev <mjt@tls.msk.ru> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2013-12-07ntpd: do not invalidate datapoints after stepDenys Vlasenko
Used to set p->filter_datapoint[i].d_dispersion = MAXDISP and clear reachable bits, but this proved to be too agressive: after step (tested with suspinding laptop for ~30 secs), this caused all previous data to be considered invalid, making us needing to collect full ~8 datapoins per peer after step in order to start trusting them. In turn, this was making poll interval decrease even after step was done. (Poll interval decreases already before step in this scenario, because we see large offsets and end up with no good peer to select). function old new delta reset_peer_stats 157 139 -18 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Commit b8b72f02 removed all padding from DHCP packets to fix operation with buggy servers which can't handle maximum sized packets. But it introduced a regression with buggy routers which drop DHCP packets smaller than 300 bytes (i.e. 342 byte ethernet packets).
