We may eventually update to a newer + version of the licenses or a combination of them. It is thus + important, that all contributed code allows for an update of the + license; for example we can't accept code under the LGPLv2(only). + + Libgcrypt used to have a strict policy of requiring copyright + assignments to the FSF. To avoid this major organizational overhead + and to allow inclusion of code, not copyrighted by the FSF, this + policy has been relaxed. It is now also possible to contribute code + by asserting that the contribution is in accordance to the + "Libgcrypt Developer's Certificate of Origin" as found in the file + "DCO". (Except for a slight wording change, this DCO is identical + to the one used by the Linux kernel.) + + If your want to contribute code or documentation to Libgcrypt and + you didn't signed a copyright assignment with the FSF in the past, + you need to take these simple steps: + + - Decide which mail address you want to use. Please have your real + name in the address and not a pseudonym. Anonymous contributions + can only be done if you find a proxy who certifies for you. + + - If your employer or school might claim ownership of code written + by you; you need to talk to them to make sure that you have the + right to contribute under the DCO. + + - Send an OpenPGP signed mail to the gcrypt-devel@gnupg.org mailing + list from your mail address. Include a copy of the DCO as found + in the official master branch. Insert your name and email address + into the DCO in the same way you want to use it later. Example: + + Signed-off-by: Joe R. Hacker <joe@example.org> + + (If you really need it, you may perform simple transformations of + the mail address: Replacing "@" by " at " or "." by " dot ".) + + - That's it. From now on you only need to add a "Signed-off-by:" + line with your name and mail address to the commit message. It is + recommended to send the patches using a PGP/MIME signed mail. + +** Coding standards + + Please follow the GNU coding standards. If you are in doubt consult + the existing code as an example. Do no re-indent code without a + need. If you really need to do it, use a separate commit for such a + change. + + +* Porting hints +** Taking optimized MPI code out of GMP: I generated the pentium4/* files by glueing the existing assembler prologues to the GMP 4.2.1 assembler files generated with the m4 @@ -42,8 +95,9 @@ Taking optimized MPI code out of GMP: tedious work. -Debugging math stuff: ---------------------- +* Debug hints + +** Debugging math stuff: While debugging the ECC code in libgcrypt, I was in need for some computer algebra system which would allow me to verify the numbers diff --git a/doc/Makefile.am b/doc/Makefile.am index a6bd2ae4..30330bb9 100644 --- a/doc/Makefile.am +++ b/doc/Makefile.am @@ -17,7 +17,7 @@ # License along with this program; if not, write to the Free Software # Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA -EXTRA_DIST = README.apichanges HACKING \ +EXTRA_DIST = README.apichanges HACKING DCO \ libgcrypt-modules.eps fips-fsm.eps \ libgcrypt-modules.png fips-fsm.png \ libgcrypt-modules.pdf fips-fsm.pdf \ |
