PulseAudio on Cygwin: Failed to create secure directory: Unknown error 13

I am unable to run PulseAudio on Cygwin.

Operating System: Windows 8 Pro 64 bit

Cygwin Setup.exe Version: 2.831 (64 bit)

PulseAudio Version: 2.1-1

When I run:

pulseaudio -vv

this is the output:

D: [(null)] core-util.c: setpriority() worked.
I: [(null)] core-util.c: Successfully gained nice level -11.

When I instead run

pulseaudio -vv --start

the output is this:

W: [autospawn] lock-autospawn.c: Cannot access autospawn lock.

When I ran strace pulseaudio -vv, the last few lines in the output were:

Try to run the utility with strace to see which "syscalls" fail: strace pulseaudio -vv --start – pabouk – 2013-11-12T12:14:48.860

@pabouk I have added the result of strace in my post. Please can you check it? – Nithin – 2013-11-12T15:18:27.223

I do not see anything new directly showing a problem in the listed output. Was not there a call testing a directory (i.e. stat()) or unsuccessful creation of a directory (mkdir())? Unfortunately I do not have any experience with peculiarities of strace on Cygwin. – pabouk – 2013-11-12T15:41:51.827

There isn't enough information here to diagnose this, and PA is WJFFM. (I'm the Cygwin PA maintainer, FWIW.) On a hunch, though, do you have a /dev/shm directory, and if so, what does it contain? – Yaakov – 2013-11-12T23:51:59.030

@pabouk There are a few stat64(), fstat64(), lstat64() and mkdir() calls near the end. I've updated my post with these entries. Please check. – Nithin – 2013-11-13T07:35:39.127

@Yaakov My /dev/shm directory is empty. I've added more lines from the strace output in my post. According to it, pulseaudio is deleting the ~/.pulse directory. Isn't it abnormal? – Nithin – 2013-11-13T08:00:05.580

I had this exact same problem until late last year with version 4.0. The latest version from cygwin (5.0) also exhibited this behavior but I found a workaround.

Here is what worked for me:

fjardon@yoda 13:22:55 ~
$ export PULSE_STATE_PATH=$HOME/.config/state

fjardon@yoda 13:23:10 ~
$ export PULSE_RUNTIME_PATH=$HOME/.config/runtime

fjardon@yoda 13:23:19 ~
$ pulseaudio.exe -vvv -p /usr/lib/pulse-5.0/modules -nF /etc/pulse/network.pa

The file /etc/pulse/network.pa is a copy of the default.pa with two lines to add support for network clients in order to stream the music from my NAS:

fjardon@yoda 13:25:16 ~
$ diff /etc/pulse/default.pa /etc/pulse/network.pa
47a48
> load-module module-native-protocol-tcp listen=127.0.0.1 auth-anonymous=1

If the program you are using is not very different from the code in the online repository then it decides to fail on this if:

if (!S_ISDIR(st.st_mode) ||
(st.st_uid != uid) ||
(st.st_gid != gid) ||
((st.st_mode & 0777) != m)) {
errno = EACCES;
goto fail;
}

The function pa_make_secure_dir() which contains the if is being called with these possible combinations of m, uid and gid depending on whether is PA called in system mode (environment variable PULSE_SYSTEM) or not:

  • 0700, -1, -1
  • 0755, -1, -1

uid and gid -1 means that pa_make_secure_dir() will use the current owner of the process.

The fstat() call returns st_mode=0x41F8 it is (after applying the mask) 0770 in octal.

What to try

Try to pre-create the directory /cygdrive/c/Users/Nithin/.pulse with mode 0700 or 0755. You can change it using chmod. Also make sure that the owner and group are the same as you run the PA under.

From the code it looks like that the umask() call did not have the desired effect and fchmod() was not called at all. Is not your home directory on FAT file system or do not you have noacl in /etc/fstab or /etc/fstab.d/$USER? See File permissions.

Note

errno value of 13 is not "Unknown error" but EACCESS - Permission denied. There is probably some problem in translating error codes into strings in pa_cstrerror().

id command gives uid=1001(Nithin) gid=513(None) groups=513(None),545(Users),1002(HomeUsers). I tried mkdir .pulse; chown -R Nithin:None .pulse; chmod -R 0700 .pulse and mkdir .pulse; chown -R Nithin:None .pulse; chmod -R 0755 .pulse. But pulseaudio -vv gives the same error in both cases. Also stat -c %a .pulse gives 770 and 775, respectively. My Cygwin home directory is the same as the Windows one and is on NTFS. My /etc/fstab contains only none /cygdrive cygdrive binary,posix=0,user 0 0. My /etc/fstab.d directory is empty. – Nithin – 2013-11-14T10:34:55.723

So stat -c "%a %u %g" /cygdrive/c/Users/Nithin/.pulse writes 700 1001 513 in the first test case and 755 1001 513 in the second test case? Also stat /cygdrive/c/Users/Nithin/.pulse writes that it is a directory? --- Check by strace if it does not fail on a different directory this time. (env. variables PULSE_STATE_PATH and PULSE_RUNTIME_PATH) --- I think without debugging of the code it will be very hard to continue. You can either recompile the program with debugging symbols enabled and use gdb or insert control point messages into the code and recompile. – pabouk – 2013-11-14T16:37:40.407

Please see the output of the commands in my question – Nithin – 2013-12-14T09:03:02.897

The access rights you showed is not what the software requires (either 0700 or 0755). See my older note. What does this code write? cd /cygdrive/c/Users/Nithin; rm -rf .pulse; mkdir .pulse; chown -R Nithin:None .pulse; chmod -R 0700 .pulse; stat -c "%a %u %g" .pulse; rm -rf .pulse; mkdir .pulse; chown -R Nithin:None .pulse; chmod -R 0755 .pulse; stat -c "%a %u %g" .pulse --- You should get: 700 1001 513 / 755 1001 513 – pabouk – 2013-12-14T15:23:51.153

The output of the command is 770 1001 513 / 775 1001 513. It seems that chmod is not working properly. – Nithin – 2013-12-14T17:34:29.577
