"I skipped the public announcements for versions 5 and 6, but here is 7 :)," noted Vegard Nossum, announcing the latest release of his kmemcheck patch, currently applying against the 2.6.25-rc8 kernel. Vegard noted he is now hoping to get the patch merged into the mainline kernel during the upcoming 2.6.26 merge window. He described the patch:
"kmemcheck is a patch to the linux kernel that detects use of uninitialized memory. It does this by trapping every read and write to memory that was allocated dynamically (e.g. using kmalloc()). If a memory address is read that has not previously been written to, a message is printed to the kernel log."
Among the changes compared to earlier releases, v7 has undergone a lot of cleanup, some preparation has begun for an x86_64 port, error reporting stability has been improved, boot time and run time options have been added, and there have been several bug fixes.
