Changes made between OpenBSD 3.5 and 3.6

• Fix tcpdump(8)'s bpf(4) attachment on atw(4) devices.
• SECURITY FIX: Eilko Bos reported that radius authentication, as implemented by login_radius(8), was not checking the shared secret used for replies sent by the radius server. This could allow an attacker to spoof a reply granting access to the attacker. Note that OpenBSD does not ship with radius authentication enabled.
  A source code patch is available.
  [Applied to stable]
• Bail out of newfs(8) on errors when making very small filesystems.
• Move MIPS to 64-bit.
• Fix copyout(9) of pf(4) anchors with relative paths and wildcards.
• Track the peer count correctly in bgpd(8) and ntpd(8), fixing memory corruption in both.
• Fix a null dereference in dhcpd(8).
• Just print the raw IP protocol number in netstat(1) instead of fetching the protocol name.
• Stop routed(8) fiddling with routes controlled by bgpd(8).
• SECURITY FIX: httpd(8)'s mod_rewrite module can be made to write one zero byte in an arbitrary memory position outside of a char array, causing a DoS or possibly buffer overflows. This would require enabling dbm for mod_rewrite and making use of a malicious dbm file.
  A source code patch is available.
  [Applied to stable]
• Stop telnetd(8) closing the slave fd from openpty(3) and then reopening it.
• Set a cleanup handler for HUP as well as INT, TERM and WINCH on the ssh(1) multiplex control socket.
• Stop ntpd(8) dying on sendmsg(2) failures.
• Unbreak route(8)'s -netmask option.

• Don't busy-wait on ENOBUFS in pppoe(8).
• Stop the mixer resetting emu(4)'s volume to very very loud.
• Make sure kernfs_xread() isn't called with a negative offset.
• SECURITY FIX: Chris Evans reported several flaws (stack and integer overflows) in the Xpm library code that parses image files (CAN-2004-0687, CAN-2004-0688). Some of these would be exploitable when parsing malicious image files in an application that handles XPM images, if they could escape ProPolice.
  A source code patch is available.
  [Applied to stable]
• Stop non-MASTER carp(4) hosts replying to ARP requests, as this upsets some layer 3 switches.
• Stop login(1) treating the 'bar' in username foo.bar as a Kerberos instance, that's a krb4 syntax we no longer use.

• Don't do DNS lookups when reading ntpd(8)'s config, save them for later.
• In ntpd(8), don't log transient network errors from sendto(2).

• Don't close stdin in sshd(8) unless we're reexec'ing.
• Make sure pkg_create(1) keeps track of the current working directory.

• In cu(1)/tip(1), if one process dies then kill the other ourselves.
• In rdate(8) NTP mode, send a 64-bit random number as the 'current time' field, which the server copies back in its response. This avoids sending out the current system time, and makes it slightly harder for an attacker to send spoof replies on behalf of the real server.
• Use _exit(2) instead of exit(3) in the sftp(1) child process.
• Include the hostname in syslogd(8) memory-buffered entries.
• Since the per-arch _dl_bcopy() in ld.so(1) is in all cases a simple for loop and not painstakingly optimised assembler, just use a single machine-independent version.

• Allow symbolic service- and protocol names in isakmpd(8), so e.g. "Protocol=tcp" now works.
• SECURITY FIX: A flaw in the Kerberos V kdc(8) server could result in the administrator of a Kerberos realm having the ability to impersonate any principal in any other realm which has established a cross-realm trust with their realm. The flaw is due to inadequate checking of the "transited" field in a Kerberos request. For more details see Heimdal's announcement.

  [Applied to stable]
• When a pf(4) scrub rule with the 'reassemble tcp' option is in effect, use RFC1913 PAWS as a means of extending the TCP sequence space by 10 to 18 bits. This makes blind insertion attacks much more difficult, because the timestamp needs to be guessed as well as the TCP sequence number.

• Greatly simplify inetd(8)'s hostname/address lookup code.
• Since OpenBSD has openpty(3), we may as well have telnetd(8) use it.

• Make netstat(1) show the number of mbuf clusters in use rather than the number of pages.
• Fix a ufs directory-related panic (PR#3672). Fix from FreeBSD.

• Allow restore(8) to recover files larger than 4GB by using size_t instead of long.
• Have dhclient(8) retry up to ten times after a second's delay for interfaces showing no link.
