Introduce new way of creating configurations: From now on, there are no configuration files as they come out of "make oldconfig" for every single architecture and kernel version. There is now a system that creates those configurations and so it is easier to track changes, see differences between architectures and a lot more. There are configuration files for armv5tel kernels but they do not build because of problems with the grsecurity patchset. -----------------------------------------------------------------------

Enabling this feature ++ makes a host more resilient to DoS attacks and reduces network ++ visibility against scanners. ++ ++ The blackhole feature as-implemented is equivalent to the FreeBSD ++ blackhole feature, as it prevents RST responses to all packets, not ++ just SYNs. Under most application behavior this causes no ++ problems, but applications (like haproxy) may not close certain ++ connections in a way that cleanly terminates them on the remote ++ end, leaving the remote host in LAST_ACK state. Because of this ++ side-effect and to prevent intentional LAST_ACK DoSes, this ++ feature also adds automatic mitigation against such attacks. ++ The mitigation drastically reduces the amount of time a socket ++ can spend in LAST_ACK state. If you're using haproxy and not ++ all servers it connects to have this option enabled, consider ++ disabling this feature on the haproxy host. ++ ++ If the sysctl option is enabled, two sysctl options with names ++ "ip_blackhole" and "lastack_retries" will be created. ++ While "ip_blackhole" takes the standard zero/non-zero on/off ++ toggle, "lastack_retries" uses the same kinds of values as ++ "tcp_retries1" and "tcp_retries2".

The randomization is done in two steps where the second ++ one may apply a big amount of shift to the top of the stack and ++ cause problems for programs that want to use lots of memory (more ++ than 2.5 GB if SEGMEXEC is not active, or 1.25 GB when it is). ++ For this reason the second step can be controlled by 'chpax' or ++ 'paxctl' on a per file basis. ++ ++config PAX_RANDMMAP ++ bool "Randomize mmap() base" ++ depends on PAX_ASLR ++ help ++ By saying Y here the kernel will use a randomized base address for ++ mmap() requests that do not specify one themselves.

slaves' state and will never reach running -state. - -This patch solves the problem by making user-stp and kernel-stp behavior -similar regarding master following slaves' states. - -Signed-off-by:

To overcome that the older version was added manually on i686. libbz2 was also moved to /usr. commit 9fc68c1ed7c308de95c28684a94bf9881a1e94b4 Author: Michael Tremer <michael.tremer(a)ipfire.org> Date: Sat Mar 31 22:33:18 2012 +0200 man-pages: Update to 3.38.
