"options edns0" in /etc/resolv.conf will enable the behavior. no behavior
change if you don't have the line. see resolv.conf(5) for more details.
EDNS0 is useful for avoiding TCP DNS queries/replies on larger DNS responses.
also, draft-ietf-dnsext-message-size-* plans to mandate EDNS0 support for DNS
clients that support IPv6 transport.
to #ifndef __cplusplus. It turns out there is code outside of libm
that wants to use this. I suppose that's why it is in math.h instead
of math_private.h ;-)
things like rm can't remove files with ridiculously long path names
that were created by some script kiddie trying in vain to exploit
something. Previously, the length was effectively constrained to
USHRT_MAX due to one of the internal structs. Also, nuke FTS_CHDIRROOT
since it never worked correctly and hasn't been documented for a
long time.
- remove extra subshells;
- use exec on terminal commands, avoiding dangling shells that don't
control anything.
More correct:
- use && some more;
- remove `-' in front of includes, so that failures WILL fail...
Okay millert@, deraadt@
draft-ietf-ipngwg-rfc2553bis-03.txt. backward compatibility concern:
- should be safe to change signed to unsigned, as we never return
negative value.
- sizeof(int) is 4 for all archs, so there's no size change with socklen_t
(= u_int32_t)

o fix typo in getsid() that broke getsid(pid) where pid != 0
o cause getsid() and getpgid() to return EPERM if requesting the
id of a session/process group not in the current session
o check for NULL session in getsid() for exiting processes
strtofflags/fflagstostr to convert file flags
to/from binary from/into a string as used in chflags(1).
use u_int32_t instead of u_long (as freebsd does).
increase libc minor.
millert@ ok.
