2013-09-11httpd: treat errors from stdin correctly.Denys Vlasenko
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. This continues until pfd[FROM_CGI].revents != 0 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

iplink.c includes net/if_packet.h, which (on GLIBC) only defines struct sockaddr_pkt. this struct is not used anywhere in the code, and removing the #include makes compilation succeed with musl libc. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

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'.

2013-01-14ntpd: fix incorrect m_status field in outgoing packets. Closes 5120Paul Marks
When using busybox ntpd with an NTPv3 client and NTPv4 server (or vice versa), the version numbers can be incorrectly ORed together, yielding the bogus value of "NTPv7". This makes ntpd unusable with clients such as Chrony and Windows "Internet Time". This patch avoids the version mangling, by copying only the Leap Indicator bits from the server's status field.
