2021-10-08libbb.h: fix logic selecting incorrect BB_STRTOOFF for !LFS configsDenys Vlasenko
BB_STRTOOFF() was equal to bb_strtou(). On x86_64, it's incorrect. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-10-08httpd: if range is not specified, correctly fall back to read/write loopDenys Vlasenko
range_start was staying -1, and comparison meant to detect "is it the first sendfile that failed, or not the first?" was making incorrect decision. The result: nothing is sent. function old new delta send_file_and_exit 865 877 +12 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

The reported case was an attempt to remount,rw a CD-ROM: mount -o remount,rw /mnt/sr0 which "succeeded" by falling back to RO: mount("/dev/sr0", "/mnt/sr0", 0x412862, MS_REMOUNT|MS_SILENT|MS_RELATIME, "nojoliet,check=s,map=n,blocksize"...) = -1 EROFS (Read-only file system) ... mount("/dev/sr0", "/mnt/sr0", 0x412862, MS_RDONLY|MS_REMOUNT|MS_SILENT|MS_RELATIME, "nojoliet,check=s,map=n,blocksize"...) = 0 Clearly, not what was intended! function old new delta parse_mount_options 241 267 +26 mount_main 1198 1211 +13 singlemount 1301 1313 +12 inetd_main 1919 1911 -8 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 3/1 up/down: 51/-8) Total: 43 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-10-07find: Unify time comparisonsIsmael Luceno
Split the common part into a function, to be reused. The tail call is optimized, meaning now mmin/mtime just prepare arguments and jump into the common code, thus near zero overhead. This reduces code size slightly, e.g. on x86_64: text data bss dec hex filename 4806 0 0 4806 12c6 findutils/find.o.orig 4782 0 0 4782 12ae findutils/find.o Of course, the savings are even greater when implementing atime/ctime variants.
