There's a lot more to translate far too many binary blobs the kernel publishes via sysctls, but I'm leaving those out in the name of simplicity. There's also a bug fix from Doug Rabson that fixes a long int confusion leading to a trunctation of addresses (oops) I've added a new command line arg -strict for debugging when you want to stop dead in the tracks when there's something unimplemented (like system calls) rather than trying one's best to cope. It will also let whoever is working on upstreaming to get something working to run it this way and find the missing bits more easily. sysctl happens to be the first unimplemented system call for a dynamically linked hello world. There's a fix for the -static option, since clang hates -no-pie and needs only -fno-pie. Finally, I'm changing how I'm upstreaming a little. I'm doing a little deeper dives into our rather chaotic repo to find a couple of authors I might have missed. From here on out, I'll be using the original author's name as the git author. I'll also tag the co-authors better as well when there's multiple people that did something (other than reformat and/or move code around). I've discovered more code moved about than I'd previously known. This seems more in line with standard practice. Also, I've reviewed all these changes, but I don't know if I need to add Reviewed-by: or not, so I've done it for one or two and will make it consistent before the pull request. git log suggests maintainers are inconsistent about this (or I've not discovered the rules they follow). check-patch gives some line lenght warnings, but should otherwise be OK. There's several static functions that aren't used until the end of the patch series... Not sure the best way to suppress the build warnings there (but since they are just warnings...). v2: o Created various helper functions to make the code a little better o split a few patches that I thought would be approved together but that generated commentary. It's easier to manage 1 per patch for those. o Add/delete G_GNU_UNUSED to ensure all patches compile w/o warnings o Fix 64-bit running 32-bit binary to get a LONG or ULONG. Add a bounce buffer for these so we don't overflow anything on the target and return all the elements of arrays. o Fixed a number of nits noticed in the review. o Add or improve comments to explain things there were questions on during the review. o fix noted typos o fix host != target page size differences o Add pointers to FreeBSD source code, as appropriate o fix locking (mostly unlocking) on error paths o Note: -strict feedback not yet applied due to large numbers of changes from the rest.
