Subject: [PATCH 00/12] e2fsprogs: some bugfixs and some code cleanups

When we learn the e2fsprogs source code, we
find some bugs and try to fix them. At the same time,
static scanning tools were used to analyze the code,
and several possible problems were found.

Zhiqiang Liu (6):
  misc: fix potential segmentation fault problem in scandir()
  lib/ss/error.c: check return value malloc in ss_name()
  hashmap: change return value type of ext2fs_hashmap_add()
  misc/lsattr: check whether path is NULL in lsattr_dir_proc()
  ext2ed: fix potential NULL pointer dereference in dupstr()
  argv_parse: check return value of malloc in argv_pars

Wu Guanghao (6):
  profile_create_node: set magic before strdup(name) to fix memory leak
  tdb_transaction_recover: fix memory leak
  zap_sector: fix memory leak
  ss_add_info_dir: fix memory leak and check whether NULL pointer
  ss_create_invocation: fix memory leak and check whether NULL pointer
  append_pathname: append_pathname: check the value returned by realloc
    to avoid segfault
