netfilter: xt_CT: recover NOTRACK target support

2012-12-24T11:55:09Z

Florian Westphal reported that the removal of the NOTRACK target (9655050 netfilter: remove xt_NOTRACK) is breaking some existing setups. That removal was scheduled for removal since long time ago as described in Documentation/feature-removal-schedule.txt What: xt_NOTRACK Files: net/netfilter/xt_NOTRACK.c When: April 2011 Why: Superseded by xt_CT Still, people may have not notice / may have decided to stick to an old iptables version. I agree with him in that some more conservative approach by spotting some printk to warn users for some time is less agressive. Current iptables 1.4.16.3 already contains the aliasing support that makes it point to the CT target, so upgrading would fix it. Still, the policy so far has been to avoid pushing our users to upgrade. As a solution, this patch recovers the NOTRACK target inside the CT target and it now spots a warning.

netfilter: xt_CT: fix crash while destroy ct templates

2012-12-16T22:44:12Z

In (d871bef netfilter: ctnetlink: dump entries from the dying and unconfirmed lists), we assume that all conntrack objects are inserted in any of the existing lists. However, template conntrack objects were not. This results in hitting BUG_ON in the destroy_conntrack path while removing a rule that uses the CT target. This patch fixes the situation by adding the template lists, which is where template conntrack objects reside now. Signed-off-by: Pablo Neira Ayuso

sctp: Make hmac algorithm selection for cookie generation dynamic

2012-10-26T06:22:18Z

Currently sctp allows for the optional use of md5 of sha1 hmac algorithms to generate cookie values when establishing new connections via two build time config options. Theres no real reason to make this a static selection. We can add a sysctl that allows for the dynamic selection of these algorithms at run time, with the default value determined by the corresponding crypto library availability. This comes in handy when, for example running a system in FIPS mode, where use of md5 is disallowed, but SHA1 is permitted. Note: This new sysctl has no corresponding socket option to select the cookie hmac algorithm. I chose not to implement that intentionally, as RFC 6458 contains no option for this value, and I opted not to pollute the socket option namespace. Change notes: v2) * Updated subject to have the proper sctp prefix as per Dave M. * Replaced deafult selection options with new options that allow developers to explicitly select available hmac algs at build time as per suggestion by Vlad Y.
