Hello busybox developers, i send you some patches i did on busybox. Not all of them are meant to be included on master. I will send a message for each patch, so in case there is discussion, the threads should not mix it up.
The first patch was a fix / workaround for a nasty problem we have seen. The mount command in one of our ARM based, linux 2.6.31.14 based boards sporadically failed with EFAULT. The linux kernels method exact_copy_from_user() which is exclusively used for the mount syscall handling, has a problem when the string is not page aligned. And for strings that are delivered as stack-pointer this is quite random. At least that was my interpretation of the problem and code. I walked the easy path and work-arounded the problem by copying the parameters for the mount syscall to heap.
