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>

2013-10-28udhcpc: make DHCP packets to have at least 300 DHCP bytesJohannes Stezenbach
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). Add back some padding to work around. function old new delta udhcp_send_kernel_packet 268 292 +24 udhcp_send_raw_packet 462 473 +11 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 35/0) Total: 35 bytes Signed-off-by: Johannes Stezenbach <js@sig21.net> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Fron bug report: If a CGI or proxied connection is rudely aborted (SIG_{KILL,BUS,SEGV}) then httpd will spin madly the poll loop in: networking/httpd.c:1080 cgi_io_loop_and_exit() Upon investigation I found that pfd[0].revents == 0x0018 (POLLHUP|POLLERR), which leads to empty read, but the pfd[0].fd (STDIN_FILENO) is left open, and in the FD list given to poll() which immediately returns to once again inform the loop of (POLLHUP|POLLERR) condition of pfd[0].fd.

2013-08-14networking: fix potential overflow in ife_print6()Nicolas Dichtel
devname is used by fscanf to store a string specified by '%20s'. Extract from the man for the '%s' specifier: Matches a sequence of non-white-space characters; the next pointer must be a pointer to character array that is long enough to hold the input sequence and the terminating null byte ('\0'), which is added automatically. The input string stops at white space or at the maximum field width, whichever occurs first. Hence, the right length is 20 + 1 for the '\0'.
