Subject: LTP 20080131 causes defunct processes w/2.6.30-rc1 (possible ptrace issue?)
Date: Thu, 9 Apr 2009 10:43:49 -0500	[thread overview]
Message-ID: <0CA2FBE3-C50C-4503-9134-6DA1C6965743@kernel.crashing.org> (raw)

I'm seeing some weird behavior in 2.6.30-rc1 that didn't exist in  
2.6.29.  We have a slightly older LTP version (20080131) that we run  
on some embedded PPC boards.  If I run the syscall tests on 2.6.29  
things pass as expected.  W/2.6.30-rc1 I start seeing a slew of  
processes that are "defunct".  I was able to trim down the tests to  
the following ones (the recv01 test will become defunct):

ptrace01 ptrace01
ptrace02 ptrace02
ptrace03 ptrace03

recv01 recv01

I'm able to reproduce this in a simulator, and am working on bisecting  
it down now.

Was wondering if there was anything ptrace related that went in that  
could possible cause this?
