I think this is acceptable from a security point of view, especially since this is an upstream change.
Before randutils.c implemented support for the getrandom() call, it used /dev/urandom. The patch simply falls back to using /dev/urandom if there is no enough entropy for getrandom(). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to util-linux in Ubuntu. https://bugs.launchpad.net/bugs/1783810 Title: [SRU] blocks boot on core18 Status in util-linux package in Ubuntu: Fix Released Status in util-linux source package in Bionic: Fix Committed Bug description: The current version of libuuid is using getrandom() without the GRND_NONBLOCK flag. This means that in early boot the boot is blocked until the crng is initialized to "level=1" which on virtual machines may take some time. Upstream fixed this in https://github.com/karelzak/util- linux/commit/a9cf659e0508c1f56813a7d74c64f67bbc962538 and we should just backport the fix. [Impact] * Makes systems that use libuuid in early boot hang [Test Case] * boot a fresh core18 system with kernel 4.15 [Regression Potential] * little, change is very targeted This is uploaded to the bionic-proposed queue now.
