https://git.stealer.net/cgit.cgi/user/sven/linux.git/atom?h=v4.13.72017-05-14T02:20:44Zscripts: Switch to more portable Perl shebang2017-05-14T02:20:44ZKamil Rytarowskin54@gmx.com2017-05-07T21:25:26Zurn:sha1:cb77f0d623ff33a7899cb945f4f5a4825fbb2ea1
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?).

KEYS: Provide a script to extract a module signature2015-10-21T14:18:36ZDavid Howellsdhowells@redhat.com2015-10-21T13:04:47Zurn:sha1:4adc605edc5f744dcf432241b5996ff6a13d868c
The supplied script takes a signed module file and extracts the tailmost
signature (there could theoretically be more than one) and dumps all or
part of it or the unsigned file to stdout.
Call as:
scripts/extract-module-sig.pl -[0adnks] module-file >out
where the initial flag indicates which bit of the signed file you want dumping
to stdout:
(*) "-0". Dumps the unsigned data with the signature stripped.
(*) "-a". Dumps all of the signature data, including the magic number.
(*) "-d". Dumps the signature information block as a sequence of decimal
numbers in text form with spaces between (crypto algorithm type,
hash type, identifier type, signer's name length, key identifier
length and signature length).
(*) "-n". Dumps the signer's name contents.
(*) "-k". Dumps the key identifier contents.
(*) "-s". Dumps the cryptographic signature contents.
In the case that the signature is a PKCS#7 (or CMS) message, -n and -k will
print a warning to stderr and dump nothing to stdout, but will otherwise
complete okay; the entire PKCS#7/CMS message will be dumped by "-s"; and "-d"
will show "0 0 2 0 0 <pkcs#7-msg-len>".
