Hi Gábor, Yes, it is ready for review, I have added the corresponding labels. Now there is nothing else to do just to wait for the reviews. Best regards, Janos From: mbed-tls <mbed-tls-bounces(a)lists.trustedfirmware.org> on behalf of Gábor Tóth via mbed-tls <mbed-tls(a)lists.trustedfirmware.org> Date: Tuesday, 23 February 2021 at 06:29 To: mbed-tls(a)lists.trustedfirmware.org <mbed-tls(a)lists.trustedfirmware.org> Subject: [mbed-tls] PR-4161-merge TLS Testing — Failures: ABI-API-checking Hello Guys! AFter a week of debugging yesterday I was able to solve the issues on my PR, but the ABI-API failure is still on. I was told that based on my changes it is OK, I should not worry. Does this mean that my PR is ready for review or it should have disappeared by now? In the second case could someone provide me the jenkins reports and some idea where should I start searching? This is my PR: https://github.com/ARMmbed/mbedtls/pull/4161 Thank you in advance! BR, Gábor

Helló János! Yes I tried that one (and plenty of other stuff). Finally I just reset the branch and recommited the changes solving this particular issue. Unfortunately I had to create a new PR, because git did not let me reopen it, but that is another topic. Thank you for the help!

Hi Gábor, If you click on the “details” link on the DCO check it will tell you which commits are missing the sign-off: https://github.com/ARMmbed/mbedtls/pull/4140/checks?check_run_id=1950600200 In this case you have one commit that is not signed off: https://github.com/ARMmbed/mbedtls/pull/4140/commits/fdd3c65ee47ab80f69cfa4… Best regards, Janos From: mbed-tls <mbed-tls-bounces(a)lists.trustedfirmware.org> on behalf of Gábor Tóth via mbed-tls <mbed-tls(a)lists.trustedfirmware.org> Date: Monday, 22 February 2021 at 11:05 To: mbed-tls(a)lists.trustedfirmware.org <mbed-tls(a)lists.trustedfirmware.org> Subject: [mbed-tls] Failing signoff (DCO) on: https://github.com/ARMmbed/mbedtls/pull/4140 Hello Guys! I know it is a newbie question, but I am not able to pass this freaking DCO test...I have used the provided commands to signoff all the commits and as I see all of them has signoff, but it still failes on one.

Hello Guys! I know it is a newbie question, but I am not able to pass this freaking DCO test...I have used the provided commands to signoff all the commits and as I see all of them has signoff, but it still failes on one. Do you have any idea what's wrong or how could I correct it? Till now I was able to correct it, but now it seems to be bugged. Thank you! BR? Gábor

Re: [mbed-tls] Use PKCS#11 and mbed TLS

by Frank Bergmann

Hi Gilles, thank you for your detailled answer. Honestly I was in fear that your answer would look like this. ;-) Do you maybe know of any plans of any software project to use mbed TLS together with a secure element? I asked SoftHSM because it looks much promising for our goals but they answered that they don't have any plans to use different ssl libs. cheers, Frank On 08.02.21 23:07, Gilles Peskine via mbed-tls wrote: > Hi Frank, > > Support for HSM keys in Mbed TLS is a work in progress.

Re: [mbed-tls] Failures: all_sh-ubuntu-16.04-test_memory_buffer_allocator

by Gilles Peskine

Hi Gábor, To reproduce locally, the correct invocation would be tests/scripts/all.sh test_memory_buffer_allocator Specifically, the failing tests are SSL tests. To reproduce those tests, build the right configuration and run tests/ssl-opt.sh -f 'DTLS fragmenting: proxy MTU, * renego' I've posted the relevant logs on the GitHub issue. It's unusual for the memory_buffer tests to fail when memory sanitizers are passing, so I don't know what's going on. -- Gilles Peskine Mbed TLS developer On 16/02/2021 11:13, Gábor Tóth via mbed-tls wrote: > Hello Guys! > > I have an error related to test_memory_buffer_allocator on the server > in my PR (https://github.com/ARMmbed/mbedtls/pull/4140).

Failures: all_sh-ubuntu-16.04-test_memory_buffer_allocator

by Gábor Tóth

Hello Guys! I have an error related to test_memory_buffer_allocator on the server in my PR (https://github.com/ARMmbed/mbedtls/pull/4140). Tried to find the issue locally on both the latest Ubuntu and on version 16.04 (same as on the server), but without success. All the tests pass if I run "make test" command (of course I changed config.h based on the component in all.sh).. I have also tried: "./tests/scripts/all.sh component_test_memory_buffer_allocator", but it does not do anything, just lists some tools. Maybe I am not using it right... The memory allocation/freeing mechanism was not touched by my changes except that in the function that frees a CRT I added a small part to free the new dynamic field. Do you have any idea what's wrong with my PR, how could I solve it or find out the cause? Thank you guys! BR, Gábor

Requesting a sample code: adding two numbers using mbedtls_mpi_add_int?

by Shariful Alam

Hello, Sorry to bother with a noob question. I am trying to understand how bignum.c works. For that, I'm trying to write a program to add two numbers. Here is what I have https://pastebin.com/mbRaE5i5, I'm not sure if this is the correct approach. I use the following to compile the code, * gcc -o mpi_example mpi_example.c bignum.c* But get the following error, /tmp/ccMo7DMW.o: In function `main': mpi_example.c:(.text+0x2d): undefined reference to `mbedtls_mpi_init' mpi_example.c:(.text+0x39): undefined reference to `mbedtls_mpi_init' mpi_example.c:(.text+0x45): undefined reference to `mbedtls_mpi_init' mpi_example.c:(.text+0x6c): undefined reference to `mbedtls_mpi_add_int' mpi_example.c:(.text+0x9a): undefined reference to `mbedtls_mpi_free' mpi_example.c:(.text+0xa6): undefined reference to `mbedtls_mpi_free' mpi_example.c:(.text+0xb2): undefined reference to `mbedtls_mpi_free' collect2: error: ld returned 1 exit status Any help what I'm doing wrong here? Or any sample code and how to compile it? Thanks, ~ Shariful

Overring bignum, aka MBEDTLS_BIGNUM_ALT?

by Fabio Utzig

Hi, I am working on adding HW acceleration to a NXP Kinetis MCU, but the HW accelerator happens to implement many operations which are defined in bignum.c, like "mbedtls_mpi_exp_mod", "mbedtls_mpi_gcd", "mbedtls_mpi_inv_mod" and so on. The bignum clients for me would be ecp.c and ecp_curves.c (as well as ecdh and ecdsa), and while I can override some of those using _ALT macros, for bignum it seems not possible to do so, short of not defining MBEDLTS_BIGNUM_C and all associated dependency issues. Also bignum itself also has other call paths that happen to use the functions I am trying to accelerate, which are themselves called by other files. Since I am using an open-source OSS and can't just override stuff in a fork, so I would like to know if there is some technical reason for an option like "MBEDTLS_BIGNUM_ALT" not being available and if such change would be acceptable?
