modpost: move the namespace field in Module.symvers last

2020-03-16T23:59:03+00:00

In order to preserve backwards compatability with kmod tools, we have to
move the namespace field in Module.symvers last, as the depmod -e -E
option looks at the first three fields in Module.symvers to check symbol
versions (and it's expected they stay in the original order of crc,
symbol, module).

In addition, update an ancient comment above read_dump() in modpost that
suggested that the export type field in Module.symvers was optional. I
suspect that there were historical reasons behind that comment that are
no longer accurate. We have been unconditionally printing the export
type since 2.6.18 (commit bd5cbcedf44), which is over a decade ago now.

Fix up read_dump() to treat each field as non-optional. I suspect the
original read_dump() code treated the export field as optional in order
to support pre <= 2.6.18 Module.symvers (which did not have the export
type field). Note that although symbol namespaces are optional, the
field will not be omitted from Module.symvers if a symbol does not have
a namespace. In this case, the field will simply be empty and the next
delimiter or end of line will follow.

modpost: add support for symbol namespaces

2019-09-10T08:30:21+00:00

Add support for symbols that are exported into namespaces. For that,
extract any namespace suffix from the symbol name. In addition, emit a
warning whenever a module refers to an exported symbol without
explicitly importing the namespace that it is defined in. This patch
consistently adds the namespace suffix to symbol names exported into
Module.symvers.

Example warning emitted by modpost in case of the above violation:

 WARNING: module ums-usbat uses symbol usb_stor_resume from namespace
 USB_STORAGE, but does not import it.

kbuild: export_report: read modules.order instead of .tmp_versions/*.mod

2019-07-17T17:19:31+00:00

Towards the goal of removing MODVERDIR aka .tmp_versions, read out
modules.order to get the list of modules to be processed. This is
simpler than parsing *.mod files in .tmp_versions.

scripts: Switch to more portable Perl shebang

2017-05-14T02:20:44+00:00

The default NetBSD package manager is pkgsrc and it installs Perl
along other third party programs under custom and configurable prefix.
The default prefix for binary prebuilt packages is /usr/pkg, and the
Perl executable lands in /usr/pkg/bin/perl.

This change switches "/usr/bin/perl" to "/usr/bin/env perl" as it's
the most portable solution that should work for almost everybody.
Perl's executable is detected automatically.

This change switches -w option passed to the executable with more
modern "use warnings;" approach. There is no functional change to the
default behavior.

While there, drop "require 5" from scripts/namespace.pl (Perl from 1994?).

export_report: use warn() to issue WARNING, so they go to stderr

2011-05-24T14:07:07+00:00

Also count CONFIG_MODVERSIONS warnings, and print a NOTE at start of
SECTION 2 if any were issued.  Section 2 will be empty if the build is
lacking this CONFIG_ item, and user may have missed the warnings, as
they're off screen.

export_report: sort SECTION 2 output

2011-05-24T14:07:07+00:00

Sort SECTION 2 modules by name.  Within those module listings, sort
the symbol providers by name, and remove the count, as it is
misleading; its the kernel-wide count of uses of that symbol, not the
count pertaining to the module being outlined.  (this can be seen by
grepping the output for a single symbol).  The count is still used to
sort the symbols.

export_report: do collectcfiles work in perl itself

2011-05-24T14:07:07+00:00

Avoid spawning a shell pipeline doing cat, grep, sed, and do it all
inside perl.  The <*.c> globbing construct works at least as far back
as 5.8.9

Note that this is not just an optimization; the sed command
in the pipeline was unterminated, due to lack of escape on the
end-of-line (\$) in the regex, resulting in this:

    $ perl ../linux-2.6/scripts/export_report.pl  > /dev/null
    sed: -e expression #1, char 5: unterminated `s' command
    sh: .mod.c/: not found

Comments on an earlier patch sought an all-perl implementation.
