[PATCH 1/5] Don't include OPT_ASM_SOURCES twice in hogweed_PURE_OBJS
by Martin Storsjö 24 Aug '14

24 Aug '14

OPT_ASM_SOURCES is already included via hogweed_OBJS. This avoids build errors about duplicate symbols in the shared library. --- Makefile.in | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/Makefile.in b/Makefile.in index 1ec807b..2db76c5 100644 --- a/Makefile.in +++ b/Makefile.in @@ -180,7 +180,7 @@ nettle_OBJS = $(nettle_SOURCES:.c=.$(OBJEXT)) $(LIBOBJS) nettle_PURE_OBJS = $(nettle_OBJS:.$(OBJEXT)=.p$(OBJEXT)) hogweed_OBJS = $(hogweed_SOURCES:.c=.$(OBJEXT)) $(… [View More]

git.lysator.liu.se temporarily down
by nisse＠lysator.liu.se 30 May '13

30 May '13

The machine git.lysator.liu.se is being upgraded to a more recent debian version. Not sure when it will be operational again (it's maintained on a volunteer basis), but hopefully within a day or two. Possibly the gitorious web interface will be replaced by something different (gitolite, gitlab, ...), since gitorious seems to require quite a bit of work to install. Sorry for the inconvenience.

arm compilation

Bug in nettle-2.7 ecc code
by nisse＠lysator.liu.se 17 May '13

17 May '13

Testing on the debian build machines revealed a bug in the new ecc code. Curiously enough, causing failures only on 32-bit sparc (see https://buildd.debian.org/status/fetch.php?pkg=nettle&arch=sparc&ver=2.7-2&…), but the bug is not really platform-specific. It turned out that ecc_j_to_a called GMP:s mpn_mul_n (via ecc_modp_mul) with overlapping input and output arguments, which is not supported. The following patch seems to solve the problem: diff --git a/ecc-j-to-a.c b/ecc-j-to-… [View More]

Portable rotates
by nisse＠lysator.liu.se 03 May '13

03 May '13

I'm rewriting the cast128 key schedule, to get rid of false warnings, and avoid lots of conditions, and to separate the rotation and the mask subkeys. Then I noticed a portability problem with the rotation macros, #define ROTL32(n,x) (((x)<<(n)) | ((x)>>(32-(n)))) For n == 0, this will work on most machines, but it's not portable, since x >> 32 gives undefined behaviour according to the C spec (when x is a 32-bit type). (On typical hardware, the result of x >> 32 … [View More]
