Makefile.flags contains: ARCH_FPIC ?= -fpic ARCH_FPIE ?= -fpie However, arch/$(ARCH)/Makefile gets included *after* Makefile.flags, and therefore doesn't get the chance to provide its own value.

2017-07-10libbb: do not die if setgid/setuid(real_id) on startup failsDenys Vlasenko
Based on a patch from Steven McDonald <steven@steven-mcdonald.id.au>: This makes 'unshare --user' work correctly in the case where the user's shell is provided by busybox itself. 'unshare --user' creates a new user namespace without any uid mappings. As a result, /bin/busybox is setuid nobody:nogroup within the namespace, as that is the only user. However, since no uids are mapped, attempting to call setgid/setuid fails, even though this would do nothing: $ unshare --user ./busybox.broken ash ash: setgid: Invalid argument 'unshare --map-root-user' still works, but because Linux only allows uid/gid mappings to be set up once, creating a root mapping makes such a namespace useless for creating multi-user containers. With this patch, setgid and setuid will not be called in the case where they would do nothing, which is always the case inside a new user namespace because all uids are effectively mapped to nobody: $ id -u 1000 $ ls -lh busybox.fixed -rwsr-xr-x 1 root root 826.2K May 21 00:33 busybox.fixed $ unshare --user ./busybox.fixed ash $ id -u 65534 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2017-07-09shuf: fix random line selection. Closes 9971Denys Vlasenko
""" For example, given input file: foo bar baz after shuffling the input file, foo will never end up back on the first line. This came to light when I ran into a use-case where someone was selecting a random line from a file using shuf | head -n 1, and the results on busybox were showing a statistical anomaly (as in, the first line would never ever be picked) vs the same process running on environments that had gnu coreutils installed. On line https://git.busybox.net/busybox/tree/coreutils/shuf.c#n56 it uses r %= i, which will result in 0 <= r < i, while the algorithm specifies 0 <= r <= i.
