Hello,
Coming back to this bug.
I noticed that supervise/ok that sv is trying to open is a named pipe not a
file. I don't know if this is telling in some way.
I attach a more detailed debug log. Problems seem to occur in __dir_lookup.
Best wishes,
João

Perhaps change the source code to set it to 0, just to be sure.

Hello Samuel,
As you suggested the open64() function being used seems to be that defined in
sysdeps/mach/hurd/open.c
However errnno is already 1073741902 before the function call, so does not
really change after the function call. On the other hand the variable fd that
stores the value returned

That's also expected: you're stepping into very critical sections,

Hello Lorenzo,
I have put sv on a debugger and seems that the failure is happening when trying
to open the supervise/ok file (the file exists, and is a 0 bytes file),
open_write() returns -1.
Here is a backtrace.
#0 open64 (__oflag=10,
9 matches
