1) All versions of Shorewall-perl mishandle per-IP rate limiting in
|
|
REDIRECT and DNAT rules. The effective rate and burst are 1/2 of
|
|
the values given in the rule.
|
|
|
|
Corrected in 4.4.7.1
|
|
|
|
2) Detection of the 'Old hashlimit match' capability was broken in
|
|
/sbin/shorewall, /sbin/shorewall-lite and in the IPv4 version of
|
|
shorecap. This problem only affects users of older distributions
|
|
such as RHEL5 and derivatives.
|
|
|
|
Corrected in 4.4.7.2
|
|
|
|
3) On older distributions such as RHEL5 and derivatives, when
|
|
LOAD_HELPERS_ONLY=No, Shorewall would fail to start if a TYPE was
|
|
specified in /etc/shorewall/tcinterfaces.
|
|
|
|
Corrected in 4.4.7.2

|
4) On older distributions such as RHEL5 and derivatives, when
|
|
LOAD_HELPERS_ONLY=Yes, Shorewall would fail to start if a TYPE was
|
|
specified in /etc/shorewall/tcinterfaces.
|
|
|
|
Corrected in 4.4.7.3
|
|
|
|
5) A CONTINUE rule specifying a log level will cause the compiler to
|
|
generate an incorrect rule sequence. The packet will be logged but
|
|
the CONTINUE action will not occur.
|
|
|
|
To work around the problem break the rule into two rules; a logging
|
|
rule and a CONTINUE rule.
|
|
|
|
Corrected in 4.4.7.5.
|
|
|
|
6) If multiple entries are present in /etc/shorewall/tcdevices and
|
|
globally unique class numbers are not explicitly specified in
|
|
/etc/shorewall/tcclasses, then 'shorewall start' will fail with a
|
|
diagnostic such as:
|
|
|
|
Setting up Traffic Control...

|

|

|
|
|
|
Corrected in 4.4.7.5.
|
|
|
|
7) If a low per-IP rate limit (such as 1/hour) is specified, the
|
|
effective enforced rate is much higher (approximately 6/min). The
|
|
Shorewall compiler now configures the hashlimit table idle timeout
|
|
based on the rate units (min, hour, ...) so that the rate is more
|
|
accurately enforced.
|
|
|
|
Corrected in 4.4.7.5.
|
|
|
|
As part of this change, a unique hash table name is assigned to
|
|
each per-IP rate limiting rule that does not specify a table name
|
|
in the rule. The assigned names are of the form 'shorewallN' where
|
|
N is an integer. Previously, all such rules shared a single
|
|
'shorewall' table which lead to unexpected results.
|
|
|
|
8) All prior versions of Shorewall-perl mishandle per-IP rate limiting
|
|
in REDIRECT, DNAT and ACCEPT+ rules. The effective rate and burst
|
|
are 1/2 of the values given in the rule.
|
|
|
|
Corrected in 4.4.7.5.
