That one is under investigation. I agree on the bug report (thanks btw), but I disagree on the fix. Basically, we can't run all hooks under nklock. For instance, the alloc_handler may issue kmalloc() calls when issued from the Linux write endpoint. However, I do agree that the current situation is a terrible mess, and that we direly need a fix. In the same move, the semantics of some handlers (namely the input one) should be sanitized. IOW, a global rework of that particular area is required. > Signed-off-by: Jan Kiszka <jan.kis...@siemens.com> > > ksrc/nucleus/pipe.c | 96 ++++++++++++++++++++++---------------------------- > 1 files changed, 42 insertions(+), 54 deletions(-) > > commit a631ab2c531d5e381ba8a0a59bf301a0276d9f99 > Author: Jan Kiszka <jan.kis...@siemens.com> > Date: Thu Jan 15 11:10:24 2009 +0100 > > POSIX: Do not auto-shadow main with dlopen enabled > > Don't perform auto-shadowing in POSIX skin if we might be loaded via > dlopen.
