[Kernel-packages] [Bug 1244627] Re: Please enable CONFIG_IMA in the ubuntu kernel
Would there be a chance to create a -ima flavor of the kernel instead of enabling it in the stock kernel flavor? This should allow for it to go into Trusty and into Saucy as a SRU, if I understand correctly, since it provides a new binary package instead of modifying an existing one (no regression for existing installs, conscious decision of the user required to install it). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1244627 Title: Please enable CONFIG_IMA in the ubuntu kernel Status in “linux” package in Ubuntu: Fix Released Status in “linux” source package in Saucy: Opinion Status in “linux” source package in Trusty: Fix Released Bug description: I would be doubly happy if this also went into the raring backport kernel. I chatted with apw and kees on #ubuntu-kernel earlier in the week. From a security engineer on our team: so I was mistaken. if CONFIG_IMA=y, the default policy is NULL unless you boot with ima_tcb=on. without ima_tcb=y, nothing is measured, nothing is audited, no performance/memory hit is incurred. Same is true for CONFIG_IMA_APPRAISE, except with the ima_appraise_tcb=on commandline parameter. ima appraise gives us the ability to sign binaries at installation time and check the signature at runtime. So we are asking that you enable CONFIG_IMA, but to not enable it via the kernel command line options. IMA would boot with an empty policy and should incur no overhead. Enterprising folks who want to run IMA can enable it in grub at their option.
