2015-05-13ash: consider "local -" case while iterating over local variables in mklocal.Eugene Rudoy
fixes segfault introduced in 0a0acb55db8d7c4dec445573f1b0528d126b9e1f with functions using "local -". test-case: f() { local -; local x; }; f note: with this change applied multiple 'local -'s still cause multiple entries to be added to the localvars list. this problem will be addressed in a separate commit.

2015-05-12libbb: Enable support for !CONFIG_MULTIUSERDaniel Thompson
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.

2015-05-11i2c-tools: only try /dev/i2c/* if opening /dev/i2c-* fails with ENOENTBartosz Golaszewski
Trying to access /dev/i2c/* on every error after opening /dev/i2c-* can mislead users who e.g. don't have root access. Instead of bailing-out with "permission denied" we currently print "no such file or directory". Fix it by trying open("/dev/i2c/%d") only if we got ENOENT. Upstream i2cdetect tries to get any info it can from /sys and /proc even when invoked by an unprivileged user, but we don't want to add unnecessary bloat.
