* | Enable seamless compression for WIN32Ron Yorston2015-05-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the archival code we pretend that WIN32 is a no-MMU platform and use the new mingw_popen_fd routine to pipe data to/from commands to compress/decompress. The pretence is maintained by redefining MMU macros in bb_archive.h. This is mostly used in the archival code but there are a handful of places where it's used to access public interfaces. The symbol BB_ARCHIVE_PUBLIC is defined in these places. With these changes: tar supports seamless compression/decompression rpm2cpio and dpkg-deb can be enabled

| * libbb: Enable support for !CONFIG_MULTIUSERDaniel Thompson2015-05-121-2/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux recently gained a new config option, CONFIG_MULTIUSER, that makes support for non-root users optional. This results in a number of syscalls being disabled: setuid, setregid, setgid, setreuid, setresuid, getresuid, setresgid, getresgid, setgroups, getgroups, setfsuid, setfsgid, capget, capset. Currently a number of busybox applets, including login, struggle to run when CONFIG_MULTIUSER is disabled. Even the root user is unable to login: login: can't set groups: Functi This patch adds code to make change_identity() a nop on single user systems. It works by recognising the signature errno value (ENOSYS, due to the system calls being disabled) and, to avoid security risks, only deploys when the current uid and target uid is the same. After the patch is applied any attempt to switch to a non-root user will fail. Thus a badly configured userspace (for example, one that tries to start a daemon as a non-root user when the kernel cannot support this) will report errors as one would expect.
