namespace: fix namespace.pl script to support relative paths

2019-10-29T08:13:21Z

[ Upstream commit 82fdd12b95727640c9a8233c09d602e4518e71f7 ] The namespace.pl script does not work properly if objtree is not set to an absolute path. The do_nm function is run from within the find function, which changes directories. Because of this, appending objtree, $File::Find::dir, and $source, will return a path which is not valid from the current directory. This used to work when objtree was set to an absolute path when using "make namespacecheck". It appears to have not worked when calling ./scripts/namespace.pl directly. This behavior was changed in 7e1c04779efd ("kbuild: Use relative path for $(objtree)", 2014-05-14) Rather than fixing the Makefile to set objtree to an absolute path, just fix namespace.pl to work when srctree and objtree are relative. Also fix the script to use an absolute path for these by default. Use the File::Spec module for this purpose. It's been part of perl 5 since 5.005. The curdir() function is used to get the current directory when the objtree and srctree aren't set in the environment. rel2abs() is used to convert possibly relative objtree and srctree environment variables to absolute paths. Finally, the catfile() function is used instead of string appending paths together, since this is more robust when joining paths together.

namespace: add source file location exceptions

2010-10-27T22:29:48Z

Teach namespace checker about some special case files where the source is in unusual location. This fixes many of the source file not found errors (more can be added), and also prevents false positives for functions not being used. Signed-off-by: Stephen Hemminger Signed-off-by: Michal Marek

Make it executable like it should be. Do the same for other files intended to be executed by the user - the ones called by the build process needn't be executable as they already work (as argument to their interpreter). Signed-off-by: Paolo 'Blaisorblade' Giarrusso Signed-off-by: Sam Ravnborg
