From: Andreas Longwitz <longwitz@incore.de> To: Scott Long <scott4long@yahoo.com> Cc: bug-followup@freebsd.org, John Baldwin <jhb@freebsd.org> Subject: Re: kern/155658: [amr] [patch] amr_ioctl(): call of malloc() causes memory corruption and panic Date: Fri, 20 Apr 2012 17:20:53 +0200 > Worst firmware ever.

I think we should just make the minimum buffer size 32k which >> should workaround this. I've updated the patch at the same URL: >> >> http://www.freebsd.org/~jhb/patches/amr_buffer_len.patch >> >> -- >> John Baldwin I have tested the updated patch, for me it is ok. Thanks you all for investigating in this problem. Andreas Longwitz
