scripts: package: mkdebian: add missing rsync dependency

2019-12-17T10:23:10Z

We've missed the dependency to rsync, so build fails on minimal containers. Fixes: 59b2bd05f5f4 ("kbuild: add 'headers' target to build up uapi headers in usr/include") Signed-off-by: Enrico Weigelt, metux IT consult Signed-off-by: Masahiro Yamada

kconfig: don't crash on NULL expressions in expr_eq()

2019-12-17T10:21:07Z

NULL expressions are taken to always be true, as implemented by the expr_is_yes() macro and by several other functions in expr.c. As such, they ought to be valid inputs to expr_eq(), which compares two expressions. Signed-off-by: Thomas Hebb Signed-off-by: Masahiro Yamada

scripts/kallsyms: fix offset overflow of kallsyms_relative_base

2019-12-14T06:53:04Z

Since commit 5e5c4fa78745 ("scripts/kallsyms: shrink table before sorting it"), kallsyms_relative_base can be larger than _text, which causes overflow when building the 32-bit kernel. https://lkml.org/lkml/2019/12/7/156 This is because _text is, unless --all-symbols is specified, now trimmed from the symbol table before record_relative_base() is called. Handle the offset signedness also for kallsyms_relative_base. Introduce a new helper, output_address(), to reduce the code duplication.

mkcompile_h: use printf for LINUX_COMPILE_BY

2019-12-14T06:53:04Z

Commit 858805b336be ("kbuild: add $(BASH) to run scripts with bash-extension") shed light on portability issues. Here is another one. Since commit f07726048d59 ("Fix handling of backlash character in LINUX_COMPILE_BY name"), we must escape a backslash contained in LINUX_COMPILE_BY. This is not working on such distros as Ubuntu. As the POSIX spec [1] says, if any of the operands contain a backslash ( '\' ) character, the results are implementation-defined. The actual shell of /bin/sh could be bash, dash, etc. depending on distros, and the behavior of builtin echo command is different among them. The bash builtin echo, unless -e is given, copies the arguments to stdout without expanding escape sequences (BSD-like behavior). The dash builtin echo, in contrast, adopts System V behavior, which does expand escape sequences without any option given. Even non-builtin /bin/echo behaves differently depending on the system. Due to these variations, echo is considered as a non-portable command. Using printf is the common solution to avoid the portability issue.

mkcompile_h: git rid of UTS_TRUNCATE from LINUX_COMPILE_{BY,HOST}

2019-12-14T06:53:04Z

UTS_VERSION is set to struct uts_namespace, hence a too long string should be truncated so it fits in 64 characters. On the other hand, LINUX_COMPILE_BY/HOST are not set to uts_namespace. They are just used in the banners, which do not have specific length limitation. I dug into the git history, but I could not find the reason why these two strings must fit in 64 characters. Remove them. Now that UTS_VERSION is the only user of UTS_TRUNCATE, I squashed it. Signed-off-by: Masahiro Yamada

checkpatch: reduce is_maintained_obsolete lookup runtime

2019-12-05T03:44:13Z

The is_maintained_obsolete function can be called twice using the same filename. This function spawns a process using get_maintainer.pl. Store the status of each filename when spawned and use the stored result to eliminate the spawning of unnecessary duplicate child processes.
