Merge lp:~gandelman-a/ubuntu/precise/ipsec-tools/merge into lp:ubuntu/precise/ipsec-tools

[Adam Gandelman]

ipsec-tools (1:0.8.0-9ubuntu1) precise; urgency=low

  * Merge from Debian unstable (LP: #881097). Remaining changes:
     - debian/control: Depend on lsb-base
     - debian/rules: switch -U_FORTIFY_SOURCE for -D_FORTIFY_SOURCE=0
  * Dropped changes:
     - Modify configure.ac to not convert -RXYZ to -Wl,-RXYZ, and regenerate
       configure (Applied in debian via configure-pass-Wl-with-R.patch)
     - debian/{racoon.init, ipsec-tools.setkey.init}: Re-write LSB init script
       (Fixed in Debian)

-.El
-.Pp
-You must specify the direction of its policy as
-.Ar direction .
-Either
-.Ar out ,
-.Ar in ,
-or
-.Ar fwd
-can be used.
-.Pp
-.Ar priority specification
-is used to control the placement of the policy within the SPD.
-Policy position is determined by
-a signed integer where higher priorities indicate the policy is placed
-closer to the beginning of the list and lower priorities indicate the
-policy is placed closer to the end of the list.
-Policies with equal priorities are added at the end of groups
-of such policies.
-.Pp
-Priority can only
-be specified when setkey has been compiled against kernel headers that
-support policy priorities (Linux \*[Gt]= 2.6.6).
-If the kernel does not support priorities, a warning message will
-be printed the first time a priority specification is used.
-Policy priority takes one of the following formats:
-.Bl -tag  -width "discard"
-.It Ar {priority,prio} offset
-.Ar offset
-is an integer in the range from \-2147483647 to 214783648.
-.It Ar {priority,prio} base {+,\-} offset
-.Ar base
-is either
-.Li low (\-1073741824) ,
-.Li def (0) ,
-or
-.Li high (1073741824)
-.Pp
-.Ar offset
-is an unsigned integer.
-It can be up to 1073741824 for
-positive offsets, and up to 1073741823 for negative offsets.
-.El
-.Pp
-.Li discard
-means the packet matching indexes will be discarded.
-.Li none
-means that IPsec operation will not take place onto the packet.
-.Li ipsec
-means that IPsec operation will take place onto the packet.
-.Pp
-The
-.Ar protocol/mode/src-dst/level
-part specifies the rule how to process the packet.
-Either
-.Li ah ,
-.Li esp ,
-or
-.Li ipcomp
-must be used as
-.Ar protocol .
-.Ar mode
-is either
-.Li transport
-or
-.Li tunnel .
-If
-.Ar mode
-is
-.Li tunnel ,
-you must specify the end-point addresses of the SA as
-.Ar src
-and
-.Ar dst
-with
-.Sq -
-between these addresses, which is used to specify the SA to use.
-If
-.Ar mode
-is
-.Li transport ,
-both
-.Ar src
-and
-.Ar dst
-can be omitted.
-.Ar level
-is to be one of the following:
-.Li default , use , require ,
-or
-.Li unique .
-If the SA is not available in every level, the kernel will
-ask the key exchange daemon to establish a suitable SA.
-.Li default
-means the kernel consults the system wide default for the protocol
-you specified, e.g. the
-.Li esp_trans_deflev
-sysctl variable, when the kernel processes the packet.
-.Li use
-means that the kernel uses an SA if it's available,
-otherwise the kernel keeps normal operation.
-.Li require
-means SA is required whenever the kernel sends a packet matched
-with the policy.
-.Li unique
-is the same as
-.Li require ;
-in addition, it allows the policy to match the unique out-bound SA.
-You just specify the policy level
-.Li unique ,
-.Xr racoon 8
-will configure the SA for the policy.
-If you configure the SA by manual keying for that policy,
-you can put a decimal number as the policy identifier after
-.Li unique
-separated by a colon
-.Sq \&:
-like:
-.Li unique:number
-in order to bind this policy to the SA.
-.Li number
-must be between 1 and 32767.
-It corresponds to
-.Ar extensions Fl u
-of the manual SA configuration.
-When you want to use SA bundle, you can define multiple rules.
-For example, if an IP header was followed by an AH header followed
-by an ESP header followed by an upper layer protocol header, the
-rule would be:
-.Dl esp/transport//require ah/transport//require ;
-The rule order is very important.
-.Pp
-When NAT-T is enabled in the kernel, policy matching for ESP over
-UDP packets may be done on endpoint addresses and port
-(this depends on the system.
-System that do not perform the port check cannot support
-multiple endpoints behind the same NAT).
-When using ESP over UDP, you can specify port numbers in the endpoint
-addresses to get the correct matching.
-Here is an example:
-.Bd -literal -offset
-spdadd 10.0.11.0/24[any] 10.0.11.33/32[any] any \-P out ipsec
-    esp/tunnel/192.168.0.1[4500]-192.168.1.2[30000]/require ;
-
-.Ed
-These ports must be left unspecified (which defaults to 0) for
-anything other than ESP over UDP.
-They can be displayed in SPD dump using
-.Nm
-.Fl DPp .
-.Pp
-Note that
-.Dq Li discard
-and
-.Dq Li none
-are not in the syntax described in
-.Xr ipsec_set_policy 3 .
-There are a few differences in the syntax.
-See
-.Xr ipsec_set_policy 3

-.Sh BUGS
-.Nm
-should report and handle syntax errors better.
-.Pp
-For IPsec gateway configuration,

-.Pq it cannot inspect upper-layer headers .

-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files

-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.

-Some influential environment variables:
-  CC          C compiler command

-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>
-  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
-              you have headers in a nonstandard directory <include dir>
-  CPP         C preprocessor
-  YACC        The `Yet Another C Compiler' implementation to use. Defaults to
-              the first program found out of: `bison -y', `byacc', `yacc'.
-  YFLAGS      The list of arguments that will be passed by default to $YACC.
-              This script will default YFLAGS to the empty string to avoid a
-              default value of `-d' given by some make applications.

-Use these variables to override the choices made by `configure' or to help
