It requires libgcrypt >= 1.6.0 so I took the version which was in devel:libraries:c_c++. When I tried first run of gnunet-arm, it failed with weird message: Fatal: can't open /dev/urandom: No such file or directory Some digging revealed failure in open_device() function (libgcrypt): #0 0x00007ffff75fc849 in raise () from /lib64/libc.so.6 #1 0x00007ffff75fdcd8 in abort () from /lib64/libc.so.6 #2 0x00007ffff72f3b04 in _gcry_logv (level=level@entry=40, fmt=fmt@entry=0x7ffff73ae595 "can't open %s: %s\n", arg_ptr=arg_ptr@entry=0x7fffffffd678) at misc.c:142 #3 0x00007ffff72f3e74 in _gcry_log_fatal (fmt=fmt@entry=0x7ffff73ae595 "can't open %s: %s\n") at misc.c:230 #4 0x00007ffff73868ed in open_device (name=0x7ffff73adf1f "/dev/urandom", retry=<optimized out>, fatal=1) at rndlinux.c:83 #5 0x00007ffff7386c88 in _gcry_rndlinux_gather_random (add=0x7ffff7383df0 , origin=RANDOM_ORIGIN_SLOWPOLL, length=60, level=1) at rndlinux.c:201 #6 0x00007ffff7383b50 in read_random_source (orgin=orgin@entry=RANDOM_ORIGIN_SLOWPOLL, length=length@entry=120, level=level@entry=1) at random-csprng.c:1288 #7 0x00007ffff7384c34 in random_poll () at random-csprng.c:1114 #8 read_pool (level=0, length=<optimized out>, buffer=0x7ffff75c60c4 "") at random-csprng.c:1008 #9 _gcry_rngcsprng_randomize (buffer=<optimized out>, length=<optimized out>, level=<optimized out>) at random-csprng.c:556 #10 0x00007ffff73839c5 in _gcry_randomize (level=GCRY_WEAK_RANDOM, length=8, buffer=0x7ffff75c60c4 ) at random.c:354 #11 _gcry_create_nonce (buffer=0x7fffffffdc8c, length=4) at random.c:479 #12 0x00007ffff79a1aad in GNUNET_CRYPTO_random_u32 () from /usr/lib64/libgnunetutil.so.9 #13 0x00007ffff7987ded in GNUNET_CRYPTO_random_init () from /usr/lib64/libgnunetutil.so.9 .. Relevant code looks like this (random/rndlinux.c): 70 fd = open (name, O_RDONLY); 71 if (fd == -1 && retry) 72 { 73 struct timeval tv; 74 75 tv.tv_sec = 5; 76 tv.tv_usec = 0; 77 _gcry_random_progress ("wait_dev_random", 'X', 0, (int)tv.tv_sec); 78 select (0, NULL, NULL, NULL, &tv); 79 goto again; 80 } 81 { 82 if (fatal) 83 log_fatal ("can't open %s: %s\n", name, strerror(errno) ); 84 return fd; 85 } 86 87 if (set_cloexec_flag (fd)) 88 log_error ("error setting FD_CLOEXEC on fd %d: %s\n", 89 fd, strerror (errno)); Lines 81-85 looks suspicious, these changes are from one chunk of libgcrypt-1.5.0-etc_gcrypt_rngseed-symlink.diff: - if (fd == -1) - log_fatal ("can't open %s: %s\n", name, strerror(errno) ); + { + if (fatal) + log_fatal ("can't open %s: %s\n", name, strerror(errno) ); + return fd; + } Is this really correct? It causes that lines 87+ are never run. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
