+ fts: do not exhaust memory when processing million-entry directories
+ Before this change, traversing (via rm -rf, find, du, etc.) an N-entry
+ directory would require about 256*N bytes of memory. Thus, it was
+ easy to construct a directory too large to be processed by any of
+ those tools. With this change, fts' maximum memory utilization is
+ now limited to around 30MB.
+ * lib/fts.c (FTS_MAX_READDIR_ENTRIES): Define.
+ (fts_read): When we've processed the final entry (i.e., when
+ ->fts_link is NULL) and fts_dirp is non-NULL, call fts_build
+ using the parent entry to read any remaining entries. Dispatch
+ depending on what fts_build returns:
+ - NULL+stop, aka failure: stop
+ - NULL otherwise: move up in the dir hierarchy
+ - non-NULL: handle this new entry
+ (fts_build): Declare and use new local, continue_readdir.
+ Prepare to be called from fts_read, when the entries
+ from a partially-read directory have just been exhausted.
+ In that case, we'll skip the opendir and instead use the parent's
+ fts_dirp and derive dir_fd from that.
+ Finally, in the readdir loop, if we read max_entries entries,
+ exit the loop ensuring *not* to call closedir. This is required
+ so that fts_dirp can be reused on a subsequent call.
+ Prompted by Ben England's report of memory exhaustion in find
+ and rm -rf vs. NFS: https://bugzilla.redhat.com/719749.
+
+ maint: fts: move decl of `dp' down into while loop; split a long line
+ * lib/fts.c (fts_build): No semantic change.
+
+ fts: add/use new struct member, fts_dirp
+ We are about to use this to manage any directory with
+ too many entries to read all of them into memory at once.
+ To do that, we'll need to save the DIR* pointer in each
+ affected FTSENT struct.
+ * lib/fts_.h: Include <dirent.h>.
+ (struct FTSENT) [fts_dirp]: New member.
+ * lib/fts.c (closedir_and_clear): Define.
+ Use it in place of closedir so that we are sure to
+ clear the new fts_dirp member when done with it.
+ (fts_alloc): Initialize the new member.
+ (fts_lfree): Free, if needed.
+
maint: fts: give __opendir2 a new parameter and rename
* lib/fts.c (__opendir2): Give it a new parameter, Pdir_fd, rather
than surreptitiously using sole caller's "dir_fd".
