Then again nabble.com seems to have a copy of the whole archive. Would there be any issue for anybody if all archives are published publicly (say in a github repository)?. Any thoughts? Greetings

[Jack-Devel] segfault in libjack from incorrect regex in jack_get_ports()

by Jörn Nettingsmeier

Hi guys, I'm seeing segfaults caused by an incorrect regex (found while fooling around to see what syntax is allowed, since it's not really documented). Turns out the correct answer to that is "regexec.c", and thus, POSIX regexes. Someone might want to put that in the docs somewhere. Thread 1 "shairport-sync" hit Breakpoint 1, jack_init (argc=<optimized out>, argv=<optimized out>) at audio_jack.c:221 221 if (config.jack_autoconnect_pattern != NULL) { (gdb) print config.jack_autoconnect_pattern $1 = 0x5c8a0 "effect_1:in{L|R}" ^--- this is likely the problem (gdb) step 222 debug(1, "config.jack_autoconnect_pattern is %s.", config.jack_autoconnect_pattern); (gdb) next 223 const char** port_list = jack_get_ports(client, config.jack_autoconnect_pattern, (gdb) step Thread 1 "shairport-sync" received signal SIGSEGV, Segmentation fault. 0x76847e8c in __regexec (preg=<optimized out>, string=0x71801e34 "system:playback_1", nmatch=0, pmatch=0x0, eflags=0) at regexec.c:243 243 regexec.c: No such file or directory. (gdb) bt #0 0x76847e8c in __regexec (preg=<optimized out>, string=0x71801e34 "system:playback_1", nmatch=0, pmatch=0x0, eflags=0) at regexec.c:243 #1 0x76f1d0f4 in ?? () from /usr/lib/arm-linux-gnueabihf/libjack.so.0 #2 0x76f1d1c4 in ?? () from /usr/lib/arm-linux-gnueabihf/libjack.so.0 #3 0x0002c988 in jack_init (argc=<optimized out>, argv=<optimized out>) at audio_jack.c:223 #4 0x00016adc in main (argc=1, argv=0x7efffc54) at shairport.c:1474 It turns out that the return value of regcomp is not checked by libjack. That's the last point where a segfault can be prevented from a simple syntax error. The only way to catch that in the application is to set up an entirely redundant regex scaffold and check the regcomp return value, before throwing it all away and letting libjack do the work all over again. In the case of configurable auto-connect patterns, which many JACK clients now offer as a sane and useful replacement of auto-connecting to system:playback_N, this SEGV is triggered by end-user action, not programmer mistake. That's a harsh user experience, and should be fixed. A brief look at the source seems to indicate the problem also exists in jack1. I don't really feel qualified to tackle this myself, since it will require lots of error handling in a multi-threaded library, which I don't know too much about... glad to help testing, though.

[Jack-Devel] What functions are missing if ALSA cannot memmap?

by Chris Caudle

I am helping check out a new ALSA driver, and it seems that jackd is not happy with the capabilities this driver provides: configuring for 48000Hz, period = 1024 frames (21.3 ms), buffer = 2 periods ALSA: mmap-based access is not possible for the capture stream of this audio interface ALSA: cannot configure capture channel Not just capture: configuring for 48000Hz, period = 1024 frames (21.3 ms), buffer = 2 periods ALSA: mmap-based access is not possible for the playback stream of this audio interface ALSA: cannot configure playback channel I am not very familiar yet with low level ALSA drivers, any tips where I should look to see what the driver messed up? Is mmap access usually a requirement for ALSA drivers? Is it technically optional but highly recommended, or it is required and this driver is just incomplete? -- Chris Caudle
