Hi all,

so here we go, 2.2.26 final. I am very proud to announce this because it fixes several of security bugs including the last mremap() bug, the longer known hashing exploit possibility in the network stack and /dev/rtc leakage.

I encourage all 2.2 kernel users to update.

Please send me all fixes/patches/etc. I've forgotten for 2.2.27-pre/rc inclusion.

Have fun :)


  • CAN-2004-0077: behave safely in case of do_munmap() failures in mremap(2) (Solar Designer)
  • CAN-2003-0984: /dev/rtc can leak parts of kernel memory to unprivileged users (2.4 backport) (Solar Designer)
  • CAN-2003-0244: hashing exploits in network stack (David S. Miller)
  • update_atime() performance improvement (2.4 backport) (Solar Designer)
  • ability to swapoff after a device file might (Solar Designer) have been re-created
  • MAINTAINERS correction for Kernel 2.2 and 2.2 fixes (me)
  • fixed some typos (Solar Designer, me)

Expect my 2.2-secure tree updated within the next days.


  • to Alan Cox for 2.2 mainline handover 8-)
  • to Solar for almost all the work
  • to Linux-Systeme GmbH for sponsoring my kernel maintenance

Kind regards
