Of course, the bug/regression only appeared in 4.15.0-45 (4.15.0-43 is fine).
In post #11, Brad Figg specifically asked us to test a fix, released in the 'proposed' repository, ASAP and report back with the result. Otherwise the proposed fix would be dropped. But on Ubuntu 16.04 (xenial-proposed) the fix is not available (yet?) or am I missing something? -- 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.
