From 664348a3afc0d35e227ec43a5558a87e53fe7333 Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Fri, 18 Mar 2016 22:15:46 +0900 Subject: [PATCH 1/9] Add facility to store multiple password verifiers This commit adds a new cluster-wide catalog table called pg_auth_verifiers extending the existing one-password value per role approach into a facility able to store multiple passwords formats for one user. This makes easier to add additional password format support in the future and is a requirement for the additional of SCRAM-SHA1. CREATE ROLE and ALTER ROLE are extended with PASSWORD VERIFIERS that allow a user to set a list of password identifiers at will, something particularly useful for pg_dump that makes use of it with this commit. password_encryption is transformed into a list able to use "md5" or "plain", or even both when CREATE/ALTER ROLE uses neither ENCRYPTED/UNENCRYPTED. pg_shadown, which had up to now the concept of storing the password plain or md5 value is now clobbered. Users and client applications are advised to switch to pg_auth_verifiers instead. The password check hook has been redesigned to be able to check a list of passwords instead of a single entry, and the related contrib module passwordcheck/ is updated respecting the new format. Extra facility for protocol aging and upgrades will be added in a different commit. Regression tests and documentation are added accordingly. --- contrib/passwordcheck/passwordcheck.c | 138 ++++++----- doc/src/sgml/catalogs.sgml | 103 +++++--- doc/src/sgml/config.sgml | 17 +- doc/src/sgml/ref/create_role.sgml | 23 +- src/backend/catalog/Makefile | 4 +- src/backend/catalog/catalog.c | 4 + src/backend/catalog/system_views.sql | 2 +- src/backend/commands/user.c | 332 +++++++++++++++++--------- src/backend/libpq/crypt.c | 72 ++++-- src/backend/nodes/copyfuncs.c | 14 ++ src/backend/nodes/equalfuncs.c | 12 + src/backend/parser/gram.y | 98 +++++++- src/backend/utils/cache/catcache.c | 1 + src/backend/utils/cache/relcache.c | 23 +- src/backend/utils/cache/syscache.c | 23 ++ src/backend/utils/misc/guc.c | 66 ++++- src/backend/utils/misc/postgresql.conf.sample | 2 +- src/bin/initdb/initdb.c | 5 +- src/bin/pg_dump/pg_dumpall.c | 77 +++++- src/include/catalog/indexing.h | 5 + src/include/catalog/pg_auth_verifiers.h | 68 ++++++ src/include/catalog/pg_authid.h | 8 +- src/include/commands/user.h | 11 +- src/include/nodes/nodes.h | 1 + src/include/nodes/parsenodes.h | 11 + src/include/parser/kwlist.h | 1 + src/include/utils/syscache.h | 2 + src/test/regress/expected/password.out | 104 ++++++++ src/test/regress/expected/roleattributes.out | 192 +++++++-------- src/test/regress/expected/rules.out | 2 +- src/test/regress/expected/sanity_check.out | 1 + src/test/regress/parallel_schedule | 2 +- src/test/regress/serial_schedule | 1 + src/test/regress/sql/password.sql | 72 ++++++ 34 files changed, 1130 insertions(+), 367 deletions(-) create mode 100644 src/include/catalog/pg_auth_verifiers.h create mode 100644 src/test/regress/expected/password.out create mode 100644 src/test/regress/sql/password.sql diff --git a/contrib/passwordcheck/passwordcheck.c b/contrib/passwordcheck/passwordcheck.c index b4c1ce0..13ad053 100644 --- a/contrib/passwordcheck/passwordcheck.c +++ b/contrib/passwordcheck/passwordcheck.c @@ -20,9 +20,11 @@ #include #endif +#include "catalog/pg_auth_verifiers.h" #include "commands/user.h" #include "fmgr.h" #include "libpq/md5.h" +#include "nodes/parsenodes.h" PG_MODULE_MAGIC; @@ -50,87 +52,93 @@ extern void _PG_init(void); */ static void check_password(const char *username, - const char *password, - int password_type, + List *passwordVerifiers, Datum validuntil_time, bool validuntil_null) { int namelen = strlen(username); - int pwdlen = strlen(password); + int pwdlen; char encrypted[MD5_PASSWD_LEN + 1]; int i; bool pwd_has_letter, pwd_has_nonletter; + ListCell *l; - switch (password_type) + foreach(l, passwordVerifiers) { - case PASSWORD_TYPE_MD5: - - /* - * Unfortunately we cannot perform exhaustive checks on encrypted - * passwords - we are restricted to guessing.
