Hi All,

The final kernel 5.5 is available for our AmigaOnes. Many thanks to all for helping me with testing, reporting, and fixing problems during the kernel 5.5 test time.

Hi All,

I released the stable kernel 5.5.3 today.

New:
  • X5000 and X1000: "conntrack" connection tracking match support (CONFIG_NETFILTER_XT_MATCH_CONNTRACK) and Connection state matching (CONFIG_NETFILTER_XT_MATCH_STATE). Allows you to match packets based on their relationship to a tracked connection (ie. previous packets). These are great solutions for a desktop firewall. Examples:

    Code: Select all

    iptables -F
    iptables -t filter -A INPUT -j DROP
    iptables -t filter -I INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
    or

    Code: Select all

    iptables -F
    iptables -t filter -A INPUT -j DROP
    iptables -t filter -I INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
    Basically, all network connections are blocked from the outside except our system has established the connections.
  • X5000: Add OF_DMA_DEFAULT_COHERENT & select it on powerpc (We don't need the coherent_cache-v4 patch anymore)
  • Linux Git log
  • Phoronix articles, reviews and news stories covering Linux 5.5
Download: linux-image-5.5.3-X1000_X5000.tar.gz

Hi All,

The stable kernel 5.5.4 is available.

New:
  • X5000 and X1000: CONFIG_NETFILTER_XT_MATCH_LIMIT (Limit matching allows you to control the rate at which a rule can be matched: mainly useful in combination with the LOG target and to avoid some Denial of Service attacks).

    For example:

    Code: Select all

    iptables -A INPUT -m tcp -p tcp --dport 22 -m state 
    --state ESTABLISHED,RELATED -j ACCEPT 
    
    iptables -A INPUT -m tcp -p tcp --dport 22 -m state 
    --state NEW -m limit --limit 3/hour --limit-burst 3 -j ACCEPT 
    
    iptables -A INPUT -m tcp -p tcp --dport 22 -j DROP
