[dm-devel] [PATCH v4 0/6] Memory issues found by coverity

[Benjamin Marzinski]

This is collection of issues found by coverity. The first three patches
deal with ev_remove_path() removing the path, but returning failure,
causing a use-after-free error. The next two patches fix memory leaks.
The final patch removes an unnecessary call to rescan_paths() from
uev_update_path()

Changes from v3:
0003: Handle NULL returns from strdup(). Suggested by Martin Wilck

Changes from v2:
0003: Combined with v2 patch 0006, with changes changes in comments,
      how the return codes are defined, and how they are handled, based
      on Martin's suggestions
0006: New patch based on Martin's suggestions about wwid change handling
      in uev_update_path().

Changes from v1:
0001: changed comment based on Martin's suggestion
0004: moved location of atexit() call based on Martin's suggestion
0006: New patch, based on Martin's comments on patch 0003

  multipathd: don't fail to remove path once the map is removed
  multipathd: remove duplicate orphan_paths in flush_map
  multipathd: fix ev_remove_path return code handling
  multipath: free vectors in configure
  kpartx: Don't leak memory when getblock returns NULL
