itojun 51156effd6 be more paranoid about UDP-based echo services validation. namely, 
reject the following sources:
	0.0.0.0/8 127.0.0.0/8 240.0.0.0/4 255.0.0.0/8
	ff00::/8 ::/128
	::ffff:0.0.0.0/96 and ::0.0.0.0/96 obeys IPv4 rule.
hint from deraadt.

mycroft 70c4e41552 Remove bogus typeof hack, and just use the type directly. 2000-07-23 22:54:51 +00:00
itojun b44d184dec permit square-bracket notation (as in RFC2732) for the first element 
in inetd.conf.  otherwise, we'll have (minor) problem putting IPv6 address in.

itojun 7bf16d3ecc explicitly check if the address family is supported, by using socket(2). 2000-07-07 14:56:45 +00:00
itojun 358c3cf8dc more change on getaddrinfo error handling. 
XXX enami, I admit it is not a good thing to check the error code from
getaddrinfo.  it is sometimes mandatory, however.  gai_strerror message
can be too generic in some cases.  we can't really extend getaddrinfo,
as it was not invented by kame (see RFC2553)
 2000-07-05 12:43:06 +00:00
itojun 798ee6865c add faithd(8) support. with "faith/tcp6" protocol specification, 
it will open a socket with setsockopt(IPV6_FAITH).

itojun 9282955dca emit more friendly message on nonexistent service name. 
From: enami
 2000-07-04 09:33:55 +00:00
itojun 0f20cdad3f check for mux service by ISMUX(), not by != NORM_TYPE 
(the assumption can bite us if we extend se_type to have more cases).
 2000-07-03 23:40:59 +00:00
itojun ee1989a0d1 remove duplicated ipsec setup code. we always call setup() on 
socket reinitialization (like SIGHUP).

fvdl 2db4d2fdfe Modify to support RPC over IPv6. 2000-06-02 23:17:55 +00:00
itojun 2e33d275dc use LOG_WARNING for syslog output for address family mismatch. 
suggested by: thorpej
 2000-05-13 06:42:13 +00:00
itojun 31eb929ec0 correct extremely unfriendly error message when the kernel does not 
support the address family (like including "tcp6" in inetd.conf, on
non-IPv6 kernel).

was:
inetd[185]: ftp/tcp6: *: hostname nor servname provided, or not known
now:
inetd[315]: ftp/tcp6: *: the address family is not supported by the kernel
 2000-05-13 02:56:47 +00:00
itojun 8fb9de8e46 fix IPsec policy parser. #@ should affect multiple lines as documented. 2000-03-06 19:52:13 +00:00
itojun 4b061adfdb sync with latest libipsec. 
since outgoing and incoming policy is separated, inetd can take multiple
policy specification, separated by ";".

itojun 55ffb1ce63 make error check against getnameinfo(). 2000-01-27 19:52:43 +00:00

ad d3f47cfba9 A colon is the preferred way to split a user and group name pair; make this 
possible and depreciate the use of dot.

itojun a77871b871 dual-stack inetd. you can write "tcp6" or "tcp4" into "protocol" field. 
(the style is the rough consensus among v6 implementers so it will be
the standard style)

hwr f6aa0f509c Prevent sending udp data to the obvious bad ports that are used for 
DoS attacks (e.g. looping packets between two echo ports).
This should "fix" PR bin/2455.
Could please anyone with an appropriate "hacker tools" check this?

thorpej 723fb3cccc Add support for specifying the send and receive socket buffer sizes. This 
is especially useful for TCP servers which must specify the receive
socket buffer size before the connection is made so that the connection's
window scale factor can be properly advertised.

Example /etc/inetd.conf configuration line:

shell stream tcp,rcvbuf=1m nowait root /usr/libexec/rshd rshd

That line will cause the rshd to advertise a 1 megabyte window, which could
improve the performance of an rcp in some situations.

mycroft a88cef6970 Ignore SIGPIPE, which may be caused by non-forking internal TCP services if 
the remote side closes the connection before we answer.

mycroft 52aae8dc8a Don't do libwrap checking for UDP services; they must do it internally on 
every packet to be correct.
 1997-04-20 22:04:59 +00:00
mycroft 14656f0069 Don't attempt to use libwrap for `stream wait' services, where 
we only have the listening socket.
 1997-03-19 00:05:05 +00:00
mycroft 95c740d58b Oops; for waiting stream services, we don't do an accept(); we 
pass down the fd of the listening socket.

mycroft 6ebf01d197 Output a + line for the tcpmux `help' service, and list itself. 1997-03-14 03:18:25 +00:00
mycroft b860cb428b Move all of the libwrap checking and subprocess startup into a separate 
function.  Arrange for tcpmux() to be called like other builtins, and have it
call the aforementioned function recursively.  This allows tcpmux to be
wrapped, and always runs it after forking, so we don't freeze everything
else.
Also, use FD_CLOEXEC to close file descriptors, rather than iterating through
them ourself.

mycroft 249eced8da If we forked for an internal service, make sure we always exit afterward. 1997-03-13 18:19:35 +00:00
mycroft df6ec691b5 If we're using libwrap. always fork. This only affects the time and daytime 
services anyway.
 1997-03-13 18:08:19 +00:00
mycroft cf5f8c252d Slight rearrangement to forking code. Also, always close the new descriptor 
after a fork failure, even for a waiting service.
