From mboxrd@z Thu Jan 1 00:00:00 1970 From: David Mosberger Date: Tue, 18 Nov 2003 21:54:41 +0000 Subject: serious multithreaded core-dumping problems Message-Id: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-ia64@vger.kernel.org While working on a new-syscall-stub-enabled libc, I noticed serious stability problems with 2.6.0-test9 when dumping core from a multi-threaded app. I thought this code had been well-tested on ia64 and multi-threaded apps, but I'm wondering now whether the code relied on implicit synchronization guarantees from LinuxThreads which don't hold for NPTL (and indeed, the code in binfmt_elf32 looks rather racy to me). Does someone have the bandwidth to investigate this? I'm willing to do it, but my plate is pretty full and I'm worried we may miss the 2.6.0 (final) if I have to look into it. --david
