kconfig/nconf: Fix hang when editing symbol with a long prompt

2017-01-09T07:22:03Z

commit 79e51b5c2deea542b3bb8c66e0d502230b017dde upstream. Currently it is impossible to edit the value of a config symbol with a prompt longer than (terminal width - 2) characters. dialog_inputbox() calculates a negative x-offset for the input window and newwin() fails as this is invalid. It also doesn't check for this failure, so it busy-loops calling wgetch(NULL) which immediately returns -1. The additions in the offset calculations also don't match the intended size of the window. Limit the window size and calculate the offset similarly to show_scroll_win().

scripts/has-stack-protector: add -fno-PIE

2016-11-26T08:56:55Z

commit 82031ea29e454b574bc6f49a33683a693ca5d907 upstream. Adding -no-PIE to the fstack protector check. -no-PIE was introduced before -fstack-protector so there is no need for a runtime check. Without it the build stops: |Cannot use CONFIG_CC_STACKPROTECTOR_STRONG: -fstack-protector-strong available but compiler is broken due to -mcmodel=kernel + -fPIE if -fPIE is enabled by default. Tagging it stable so it is possible to compile recent stable kernels as well. Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Michal Marek Signed-off-by: Greg Kroah-Hartman

scripts/recordmcount.c: account for .softirqentry.text

2016-09-28T23:19:02Z

be7635e7287e ("arch, ftrace: for KASAN put hard/soft IRQ entries into separate sections") added .softirqentry.text section, but it was not added to recordmcount. So functions in the section are untracable. Add the section to scripts/recordmcount.c and scripts/recordmcount.pl.

scripts/faddr2line: improve on base path filtering a bit

2016-09-19T21:49:08Z

Due to our compiler include directives, the build pathnames for header files often end up being of the form "$srcdir/./include/linux/xyz.h", which ends up having that extra "." path component after the build base in it. Teach faddr2line to skip that too, to make code generated in inline functions in header files match the filename for the regular C files. Rabin Vincent pointed out that I can't make a stricter regexp match by using the " at " prefix for the pathname, because that ends up being locale-dependent. But this does require that the path match be preceded by a space, to make it a bit more strict (that matters mainly if we didn't find any base_dir at all, and we only end up with the "./" part of the match) Acked-by: Josh Poimboeuf Cc: Rabin Vincent Signed-off-by: Linus Torvalds

scripts: add script for translating stack dump function offsets

2016-09-19T19:00:30Z

addr2line doesn't work with KASLR addresses. Add a basic addr2line wrapper script which takes the 'func+offset/size' format as input. Signed-off-by: Josh Poimboeuf Signed-off-by: Linus Torvalds

get_maintainer: quiet noisy implicit -f vcs_file_exists checking

2016-08-27T00:39:34Z

Checking command line filenames that are outside the git tree can emit a noisy and confusing message. Quiet that message by redirecting stderr. Verify that the command was executed successfully.

builddeb: Skip gcc-plugins when not configured

2016-08-16T08:16:38Z

When attempting to build a Debian kernel package, the "scripts/gcc-plugins" directory does not exist in the output tree unless CONFIG_GCC_PLUGINS=y. To avoid errors when not defined, this wraps the failing "find" in a config test. Reported-by: Frank Paulsen Tested-by: Christian Kujau Signed-off-by: Kees Cook Signed-off-by: Michal Marek

get_maintainer: Don't check if STDIN exists in a VCS repository

2016-08-10T17:42:00Z

If get_maintainer is not given any filename arguments on the command line, the standard input is read for a patch. But checking if a VCS has a file named &STDIN is not a good idea and fails. Verify the nominal input file is not &STDIN before checking the VCS.
