* sign-file: fix the perl warning message when extracting ASN.1Chun-Yi Lee2012-11-211-3/+3
| | | | | | | | | | | | | | | | | | | There have the following warning message when running modules install for sign ko files: # make modules_install ...

Found = in conditional, should be == at scripts/sign-file line 159. This patch change replace '=' by '==' in elsif conditions for avoid the above warning messages.

* | MODSIGN: Move the magic string to the end of a module and eliminate the searchDavid Howells2012-10-201-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Emit the magic string that indicates a module has a signature after the signature data instead of before it. This allows module_sig_check() to be made simpler and faster by the elimination of the search for the magic string. Instead we just need to do a single memcmp(). This works because at the end of the signature data there is the fixed-length signature information block. This block then falls immediately prior to the magic number. From the contents of the information block, it is trivial to calculate the size of the signature data and thus the size of the actual module data.

* | kbuild: Fix module signature generationLinus Torvalds2012-10-191-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rusty had clearly not actually tested his module signing changes that I (trustingly) applied as commit e2a666d52b48 ("kbuild: sign the modules at install time"). That commit had multiple bugs: - using "${#VARIABLE}" to get the number of characters in a shell variable may look clever, but it's locale-dependent: it returns the number of *characters*, not bytes. And we do need bytes. So don't use "${#..}" expansion, do the stupid "wc -c" thing instead (where "c" stands for "bytes", not "characters", despite the letter. - Rusty had confused "siglen" and "signerlen", and his conversion didn't set "signerlen" at all, and incorrectly set "siglen" to the size of the signer, not the size of the signature. End result: the modified sign-file script did create something that superficially *looked* like a signature, but didn't actually work at all, and would fail the signature check. Oops. Tssk, tssk, Rusty. But Rusty was definitely right that this whole thing should be rewritten in perl by somebody who has the perl-fu to do so. That is not me, though - I'm just doing an emergency fix for the shell script. Cc: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * MODSIGN: Sign modules during the build processDavid Howells2012-10-102-1/+191

The following steps will occur: (1) The module will be linked to foo.ko.unsigned instead of foo.ko (2) The module will be stripped using both "strip -x -g" and "eu-strip" to ensure minimal size for inclusion in an initramfs. (3) The signature will be generated on the stripped module. (4) The signature will be appended to the module, along with some information about the signature and a magic string that indicates the presence of the signature. Step (3) requires private and public keys to be available. By default these are expected to be found in files: signing_key.priv signing_key.x509 in the base directory of the build. The first is the private key in PEM form and the second is the X.509 certificate in DER form as can be generated from openssl: openssl req \ -new -x509 -outform PEM -out signing_key.x509 \ -keyout signing_key.priv -nodes \ -subj "/CN=H2G2/O=Magrathea/CN=Slartibartfast" If the secret key is not found then signing will be skipped and the unsigned module from (1) will just be copied to foo.ko. If signing occurs, lines like the following will be seen: LD [M] fs/foo/foo.ko.unsigned STRIP [M] fs/foo/foo.ko.stripped SIGN [M] fs/foo/foo.ko will appear in the build log. If the signature step will be skipped and the following will be seen: LD [M] fs/foo/foo.ko.unsigned STRIP [M] fs/foo/foo.ko.stripped NO SIGN [M] fs/foo/foo.ko NOTE! After the signature step, the signed module _must_not_ be passed through strip. The unstripped, unsigned module is still available at the name on the LD [M] line. This restriction may affect packaging tools (such as rpmbuild) and initramfs composition tools. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

The script takes the Subject Name and extracts (if present) the organizationName (O), the commonName (CN) and the emailAddress and fabricates the signer's name from them: (1) If both O and CN exist, then the name will be "O: CN", unless: (a) CN is prefixed by O, in which case only CN is used. (b) CN and O share at least the first 7 characters, in which case only CN is used. (2) Otherwise, CN is used if present. (3) Otherwise, O is used if present. (4) Otherwise the emailAddress is used, if present. (5) Otherwise a blank name is used. The script emits a binary encoded identifier in the following form: - 2 BE bytes indicating the length of the signer's name. - 2 BE bytes indicating the length of the subject key identifier. - The characters of the signer's name. - The bytes of the subject key identifier.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a simple ASN.1 grammar compiler. This produces a bytecode output that can be fed to a decoder to inform the decoder how to interpret the ASN.1 stream it is trying to parse. Action functions can be specified in the grammar by interpolating: ({ foo }) after a type, for example: SubjectPublicKeyInfo ::= SEQUENCE { algorithm AlgorithmIdentifier, subjectPublicKey BIT STRING ({ do_key_data }) } The decoder is expected to call these after matching this type and parsing the contents if it is a constructed type. The grammar compiler does not currently support the SET type (though it does support SET OF) as I can't see a good way of tracking which members have been encountered yet without using up extra stack space. Currently, the grammar compiler will fail if more than 256 bytes of bytecode would be produced or more than 256 actions have been specified as it uses 8-bit jump values and action indices to keep space usage down.

I clocked it at 15+mins for a SUSE kernel like config on a fast system. And tarxz and bzip2 are even slower. The main reason is that the script that is doing the taring sets the highest compression level (-9). When I change it to just use the defaults the gzip time for the same kernel goes down to ~3 mins. I haven't tested xz and bzip, but I expect those to be much faster too. I'm not willing to wait that long for a small compression gain. So just change the script to use the defaults.

The first one fixes gcc -x <language> syntax in various build-time tests, which icecream and possible other gcc wrappers did not understand (and yes, icecream is going to be fixed as well). The second one fixes make tar-pkg so that unpacking the tarball does not replace the /lib -> /usr/lib symlink on recent Fedora releases." * 'rc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: kbuild: Fix gcc -x syntax kbuild: Do not package /boot and /lib in make tar-pkg

Even though the latter happens to work, the former is what is documented in the manual page and thus what gcc wrappers such as icecream do expect. This isn't a cosmetic change. The missing space prevents icecream from recognizing compilation tasks it can't handle, leading to silent kernel miscompilations. Besides me, credits go to Michael Matz and Dirk Mueller for investigating the miscompilation issue and tracking it down to this incorrect -x parameter syntax.

These sections are output using mono-type fonts. However, leading whitespace is stripped, thus robbing a lot of meaning from this, as indented code examples will be mangled. This patch preserves the leading whitespace for "Example" sections. More accurately, it preserves it for all sections, but removes it later if the section isn't an "Example" section.
