Dear debian-bsd@ readers,I'd like to draw your attention to this coreutils bug, which happens to trigger on kFreeBSD 7:
| $ mkdir -p a/b/{c,d}
| $ rm -Rf a/
| rm: cannot remove `a/b': Operation not permitted
My not entirely fruitful debugging showed that something icky happens in
line 75 of src/remove.c:
if (st->st_size == -1 && fstatat (fd, file, st, flag) != 0)The relevant part of ktrace output, which does make no sense at all to me, is:
| 2676 rm CALL __sysctl(0xbfbfe628,0x4,0,0xbfbfe638,0,0) | 2676 rm RET __sysctl 0 | 2676 rm CALL __sysctl(0xbfbfe628,0x4,0xbfbfdce0,0xbfbfe638,0,0) | 2676 rm RET __sysctl 0 | 2676 rm CALL lstat(0xbfbfe5a8,0xbfbfdc50) | 2676 rm NAMI "-/b" | 2676 rm RET lstat -1 errno 2 No such file or directory (Note, that it's "-/b", not "a/b".) Also, it might be interesting that: - The problem goes away if coreutils is compiled with -O0.- Despite fstatat() being not detected at configure time, rm uses the __fxstatat symbol.
