Hello, The attached patch corrects the name used for the windows dlls. With the current naming, it is not possible to update an existing version of nettle by dropping the new files in place and the patch fixes that. regards, Nikos

patch to use gitlab runners with libasan and libubsan
by Nikos Mavrogiannopoulos 15 Mar '16

15 Mar '16

Hello, I've now completed enabling the undefined sanitizer for gnutls, and may be a good idea to use it for nettle to. The following patch enables running the test suite of nettle under libasan (to detect any invalid memory accesses/writes), and the undefined sanitizer. I've run a test build, and the libasan build succeeds but the libubsan builds fail: https://gitlab.com/gnutls/nettle/builds/773956 Its complaints are not that critical for the targetted platforms but may be nice not to rely on undefined behavior. regards, Nikos

abort / assert issues in sexp-conv
by Hanno Böck 16 Feb '16

16 Feb '16

Hi, I did a quick fuzzing test of the command line tools coming with nettle. echo "]"|sexp-conv will cause an abort call and echo "{MiM}"|sexp-conv causes an assert: sexp-conv: /var/tmp/portage/dev-libs/nettle-3.2/work/nettle-3.2/tools/input.c:128: sexp_input_start_coding: Assertion `!input->coding' failed. Not sure how relevant these tools are, but usually abort/assert calls are debugging tools for situations in a software that should never happen on normal operations. -- Hanno Böck https://hboeck.de/ mail/jabber: hanno(a)hboeck.de GPG: BBB51E42

backporting ecc patches
by Nikos Mavrogiannopoulos 09 Feb '16

09 Feb '16

Hello Niels, Do you plan a backport of the carry propagation fix in secp384 [0] for nettle 2.7.1? My limited understanding of the 3.2 assembly file wouldn't work out of the box in 2.7 due to the change from ecc_curve to ecc_modulus. The fix for the secp256r1 issue [1] looks quite trivial to backport if p->m is replaced by ecc->p. Is my understanding correct? regards, Nikos [0]. https://git.lysator.liu.se/nettle/nettle/commit/fa269b6ad06dd13c90 1dbd84a12e52b918a09cd7 [1]. https://git.lysator.liu.se/nettle/nettle/commit/c71d2c9d20eeebb985 e3872e4550137209e3ce4d
