L.S.,
The Debian kernel-package tool make-kpkg for easy building of upstream kernels on Debian fails with linux 4.16-rc1.
The tool (perl script) while invoked with: make-kpkg --initrd --append_to_version -20180212 kernel_image
On a git tree with a .config from the previous kernel release, so new KConfig questions have to be asked on new or changed options.
The script stalls indefinitely while it seems to be excuting: exec make kpkg_version=13.018+nmu1 -f /usr/share/kernel-package/ruleset/minimal.mk debian APPEND_TO_VERSION=-t440s-20180212 INITRD=YES
After using ctrl-c to break out it, i get: ^CFailed to create a ./debian directory: No such file or directory at /usr/bin/make-kpkg line 970.
Bisection turned up as culprit: commit d2a04648a5dbc3d1d043b35257364f0197d4d868 kconfig: remove check_stdin()
Except silentoldconfig, valid_stdin is 1, so check_stdin() is no-op.
oldconfig and silentoldconfig work almost in the same way except that the latter generates additional files under include/. Both ask users for input for new symbols.
I do not know why only silentoldconfig requires stdio be tty.
$ rm -f .config; touch .config $ yes "" | make oldconfig > stdout $ rm -f .config; touch .config $ yes "" | make silentoldconfig > stdout make[1]: *** [silentoldconfig] Error 1 make: *** [silentoldconfig] Error 2 $ tail -n 4 stdout Console input/output is redirected. Run 'make oldconfig' to update configuration. scripts/kconfig/Makefile:40: recipe for target 'silentoldconfig' failed Makefile:507: recipe for target 'silentoldconfig' failed Redirection is useful, for example, for testing where we want to give particular key inputs from a test file, then check the result.

Reverting this specific commit makes make-kpkg work again as usual.
Version of the kernel-package used: ii kernel-package 13.018+nmu1
