...that ogg123 crashes on his machine with a SIGSEGV while playing tracks with unknown comments in the tags. He's running with special malloc flags that make the OpenBSD malloc(3) extra picky (manpage available online at http://www.openbsd.org/cgi-bin/man.cgi?query=malloc.conf - Claudio was using MALLOC_OPTIONS=FGJ) These options quite often uncover malloc related bugs and are a useful asset when developing code on OpenBSD. As it turns out, there is a bug in ogg123s use of strcspn(3) - it should never return 0 unless the '='-sign is the first character (quite unlikely). Claudio proposed a patch...

...It all worked, and I can actually run the resulting executable. Unfortunately it doesn't get far. The first time it calls malloc, malloc tries to call sbrk (I think it's sbrk) twice and those calls return invalid argument errors. Malloc then returns 0. I used ktrace and the "U" malloc_option to determine this --- the calls show up as follows: 89021 testit CALL readlink(0x680bbf14,0xbfbff3b0,0x3f) 89021 testit NAMI "/etc/malloc.conf" 89021 testit RET readlink -1 errno 2 No such file or directory 89021 testit CALL utrace(0xbfbff3a4,0xc) 89021 testit USER...

MacOS, well, I always try it but it has problems. What's the problem on OS X? We test on it regularly (El Capitan and High Sierra) and the only problem I'm aware of is that the native libcrypto on High Sierra is

...0x800 is ZEROSIZEPTR and is set when a zero length is passed to malloc() unless you have malloc_sysv set. The thing is, i don't know if this behaviour is intentional or not, but certainly is not documented -- the manpage documents something totally different (in the section for the 'V' MALLOC_OPTION, see below). TUNING ... V Attempting to allocate zero bytes will return a NULL pointer instead of a valid pointer. (The default behavior is to make a minimal allocation and return a pointer to it.) This option is provided for System V comp...

We have a little soekris box running freebsd that uses racoon for key management. It's used for setting up an ipsec tunnel. I noticed that one of these devices lost the tunnel this morning. I looked in the log and saw this Jul 23 01:37:57 m0n0wall /kernel: pid 80 (racoon), uid 0, was killed: out of swap space I reproduced this problem using this code. #include <stdlib.h> int

Hello everyone! Could you tell me if FreeBSD supports memory page nulling when releasing it to prevent unauthorized access to data left in the page after it's allocated again. If it does, what sys calls etc provide that? IMHO this is an important issue when operating data with different sensivity levels. Thanks in advance. Nick

Hi, The main (and probably the only) use case of this PAM module is to let sudo authenticate users via their ssh-agent, therefore without having to type any password and without being tempted to use the NOPASSWD sudo option for such convenience. The principle is originally implemented by an existing module [0][1] and many pages that explain how to use it for such purpose can be found online.
