Shorewall 5.2.0 Beta 1 is now available for download. Problems Corrected:
1) This release includes defect repair through Shorewall 5.1.12.1.
2) Under rare rare circumstances, syn flood limiting specified in a
policy was previously not enforced by the generated ruleset. That
has been corrected.
New Features:
) The MAPOLDACTIONS option in shorewall.conf has been removed. This
option provided compatibility with releases prior to Shorewall 3.0.
'shorewall update' will remove the setting of this option from
shorewall.conf.
2) The INLINE_MATCH option has been removed. Shorewall now behaves as
if INLINE_MATCH=No had been specified:
- A single semicolon (';') is used to separate column-oriented
input from column-name/value input.
- The preferred method of specifying column-name/value input is to
enclose such input in curly braces ("{....}").
- A pair of semicolons (';;') is used to introduce raw IP[6]TABLES
input. This is true in INLINE and IP[6]TABLES rules as well as
rules with other targets.
As part of this change, 'shorewall update' will replace ';' with
';;' in INLINE and IP[6]TABLES rules.
3) With the wide availability of ipset-based blacklisting, the need
for the 'refresh' command has been largely eliminated. As a result,
that command has been removed.
4) The following deprecated macros and actions have been removed:
Action A_AllowICMPs - use AllowICMPs(A_ACCEPT)
Action A_Drop - see below
Action A_Reject - see below
Action Drop - see below
Action Reject - see below
Macro SNMPTrap - use SNMPtrap
The [A_]Drop and [A_]Reject actions are used primarily as policy
actions. As part of this change, 'shorewall update' will update
DROP_DEFAULT=[A_]Drop and REJECT_DEFAULT=[A_]Reject as follows:
IPv4
DROP_DEFAULT=Drop becomes Broadcast(DROP),Multicast(DROP)
DROP_DEFAULT=A_Drop becomes
Broadcast(A_DROP),Multicast(A_DROP)
REJECT_DEFAULT=Reject becomes Broadcast(DROP),Multicast(DROP)
REJECT_DEFAULT=A_Reject becomes
Broadcast(A_DROP),Multicast(A_DROP)
IPv6
DROP_DEFAULT=Drop becomes
AllowICMPs,Broadcast(DROP),Multicast(DROP)
DROP_DEFAULT=A_Drop becomes
AllowICMPs(A_ACCEPT),Broadcast(A_DROP),Multicast(A_DROP)
REJECT_DEFAULT=Reject becomes
AllowICMPs,Broadcast(DROP),Multicast(DROP)
REJECT_DEFAULT=A_Reject becomes
AllowICMPs(A_ACCEPT),Broadcast(A_DROP),Multicast(A_DROP)
See the Migration Issues for additional information.
5) A 'show saves' command has been added to list the snapshots
created using the 'save' command.
Example:
root@gateway:~# shorewall show saves
Shorewall 5.2.0 Saves at gateway - Thu Feb 15 11:58:37 PST 2018
Saved snapshots are:
Feb 15 10:08 foo
Feb 14 12:34 restore (default)
root@gateway:~#
The snapshots are listed by creation time from latest to
earliest. If the name of one matches the RESTOREFILE setting, that
snapshot is marked as the default for the 'restore' command.
6) For installing into a Sandbox, the file shorewallrc.sandbox has
been added to Shorewall-core. See
http://www.shorewall.net/install.htm#idm327.
7) The "Use Pkttype Match (USEPKTTYPE)" capability is no longer used
and has been deleted. This removal has introduced a new
capabilities version.
8) When a log message is issued from a chain that relates to a pair of
zones (e.g, 'fw-net'), the chain name normally appears in the log
message (unless LOGTAGONLY=Yes and a log tag is specified). This
can prevent OPTIMIZE category 8 from combining chains which are
identical except for chain names in logging rules. The new
LOG_ZONE option in shorewall[6].conf allows for only the source or
destination zone to appear in the messages by setting LOG_ZONE to
'src' or 'dst' respectively. If LOG_ZONE=both (the default), then
the full chain name is included in log messages
Setting LOG_ZONE=src has been shown to decrease the size of the
generated ruleset by more than 10 prcent in some cases. Your
results may vary.
Thank you for testing,
-Tom
