* binmiscctl(8): miscellaneous cleanupKyle Evans2020-11-071-11/+11
| | | | | | | | | | | | - Bad whitespace in Makefile. - Reordered headers, sys/ first. - Annotated fatal/usage __dead2 to help `make analyze` out a little bit. - Spell a couple of sizeof constructs as "nitems" and "howmany" instead. MFC after: 1 week Notes: svn path=/head/; revision=367441
* Don't leak resources on duplicate -m or -M arguments. Last one wins.Warner Losh2017-12-281-0/+2

* binmiscctl should use modfind instead of kldfindSean Bruno2017-07-281-1/+2
| | | | | | | | | | | | | | | | | kldfind() only matches kernel modules, so if you link imgact_binmisc directly into the kernel, binmiscctl can't find it, tries to load it, and errors out with: Can't load imgact_binmisc kernel module: File exists A quick search of other base commands shows that the correct procedure is to call modfind(), and then try kldload() if that fails.

* Another attempt at resolving CID 1305629. The test of cmd == -1Don Lewis2016-05-131-1/+1
| | | | | | | | | | | | may make Coverity think that other negative values of cmd (used as an index) are possible. Testing < 0 is a more common idiom in any case. Reported by: Coverity CID: 1305629 Notes: svn path=/head/; revision=299687
* Revert r299584:Don Lewis2016-05-131-1/+1
| | | | | | | | | | Mark usage() as __dead2 so that Coverity doesn't think that execution continues after the call and uses a negative array subscript. Requested by: bde Notes: svn path=/head/; revision=299588

execution to a emumation program via parsing of ELF header information. With this kernel module and userland tool, poudriere is able to build ports packages via the QEMU userland tools (or another emulator program) in a different architecture chroot, e.g. TARGET=mips TARGET_ARCH=mips I'm not connecting this to GENERIC for obvious reasons, but this should allow the kernel module to be built by default and enable the building of the userland tool (which automatically loads the kernel module).
