You don't seem to understand what I said: I DO HAVE 4.15.0 installed (linux-generic-hwe-16.04): https://packages.ubuntu.com/search?keywords=linux-generic-hwe-16.04&searchon=names&suite=xenial-updates§ion=all
running 'apt-get install -t xenial-proposed linux-generic-hwe-16.04' does NOT pull any new/updated 4.15.0 kernel from xenial-proposed. To double check that I configured xenial-proposed correctly, I installed linux-generic, wich DOES have an update waiting (4.4.0-143 in xenial- proposed over 4.4.0-142 from xenial/main): -- 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/1813873 Title: Userspace break as a result of missing patch backport Status in linux package in Ubuntu: Fix Committed Status in linux source package in Xenial: Fix Committed Status in linux source package in Bionic: Fix Committed Status in linux source package in Cosmic: Fix Released Bug description: Hi, The most recent set of Ubuntu kernels applied a variety of tty patches including: https://github.com/torvalds/linux/commit/c96cf923a98d1b094df9f0cf97a83e118817e31b But have not applied the more recent https://github.com/torvalds/linux/commit/d3736d82e8169768218ee0ef68718875918091a0 patch. This second patch is required to prevent a rather serious regression where userspace applications reading from stdin can receive EAGAIN when they should not. I will try to link correspondence from the mailing list archives once they are available, but for now if you have access to the linux- console mailing list you can find discussion under the thread "Userspace break? read from STDIN returns EAGAIN if tty is "touched"". I would appreciate it if this could be examined soon as it is a regression on userspace.
