This is caused by the fact that linux/i2c-dev.h from i2c-tools overwrites the one from linux uapi and defines symbols already defined by linux' linux/i2c.h. Drop this include and simply re-implement the relevant defines from linux/i2c-dev.h in miscutils/i2c-tools.c. Tested by building on systems with and without i2c-tools headers.

Denys Vlasenko	036585a911	getopt32: remove applet_long_options FEATURE_GETOPT_LONG made dependent on LONG_OPTS. The folloving options are removed, now LONG_OPTS enables long options for affected applets: FEATURE_ENV_LONG_OPTIONS FEATURE_EXPAND_LONG_OPTIONS FEATURE_UNEXPAND_LONG_OPTIONS FEATURE_MKDIR_LONG_OPTIONS FEATURE_MV_LONG_OPTIONS FEATURE_RMDIR_LONG_OPTIONS FEATURE_ADDGROUP_LONG_OPTIONS FEATURE_ADDUSER_LONG_OPTIONS FEATURE_HWCLOCK_LONG_OPTIONS FEATURE_NSENTER_LONG_OPTS FEATURE_CHCON_LONG_OPTIONS FEATURE_RUNCON_LONG_OPTIONS They either had a small number of long options, or their long options are essential. Example: upstream addgroup and adduser have ONLY longopts, we should probably go further and get rid of non-standard short options. To this end, make addgroup and adduser "select LONG_OPTS". We had this breakage caused by us even in our own package! #if ENABLE_LONG_OPTS \|\| !ENABLE_ADDGROUP /* We try to use --gid, not -g, because "standard" addgroup * has no short option -g, it has only long --gid. / argv[1] = (char)"--gid"; #else /* Breaks if system in fact does NOT use busybox addgroup / argv[1] = (char)"-g"; #endif xargs: its lone longopt no longer depends on DESKTOP, only on LONG_OPTS. hwclock TODO: get rid of incompatible -t, -l aliases to --systz, --localtime Shorten help texts by omitting long option when short opt alternative exists. Reduction of size comes from the fact that store of an immediate (an address of longopts) to a fixed address (global variable) is a longer insn than pushing that immediate or passing it in a register.

Bartosz Golaszewski	59f8197624	i2cdump: don't use common_bufsiz1 Commit `e6a2f4cc` changed the way common_bufsiz1 works. Now it needs to be initialized before using, but i2cdump wasn't updated by said patch. Since the fact that we're using common_bufsiz1 here isn't obvious (no G_INIT() macro, no other global variables), drop it and simply allocate the integer array required for block reads on the stack.

Arnout Vandecappelle (Essensium/Mind)	5fa9fefddc	taskset: fix non-fancy cpuset printing on big-endian The non-fancy version of the from_cpuset uses CPU_SETSIZE as if it represents the number of bytes in the cpuset, while it is actually the number of bits. This leads to out-of-bounds accesses on the cpu_set_t in the big-endian case. Basically all uses of CPU_SETSIZE have to be divided by 8. This is done correctly in the fancy version of from_cpuset. In addition, the big-endian case is completely wrong to begin with. All standard C libraries that I know of implement cpu_set_t as an unsigned long array, so both for big and little endian, the least significant bits are in the beginning of the array. Therefore, the approach taken for the little endian case is equally valid. We only need special handling for big endian when CPU_SETSIZE is large and we use an unsigned long long to get more bits out.
