The session is therefore freed with the IDA's backing\nxarray still intact.\n\nThe kernel IDA API expects ida_init() and ida_destroy() to be paired\nover an object's lifetime, so add the missing cleanup before the\nenclosing session is freed.\n\nAlso move ida_init() to right after the session is allocated so that\nit is always paired with the destroy call even on the early error\npaths of __session_create() (ksmbd_init_file_table() or\n__init_smb2_session() failures), both of which jump to the error\nlabel and invoke ksmbd_session_destroy() on a partially initialised\nsession.\n\nNo leak has been observed in testing; this is a pairing fix to match\nthe IDA lifetime rules, not a response to a reproduced regression.\n\nFixes: d40012a83f87 (\"cifsd: declare ida statically\")\nSigned-off-by: DaeMyung Kang <charsyam@gmail.com>\n---\n fs/smb/server/mgmt/user_session.c | 5 +++--\n 1 file changed, 3 insertions(+), 2 deletions(-)", "diff": "diff --git a/fs/smb/server/mgmt/user_session.c b/fs/smb/server/mgmt/user_session.c\nindex a86589408835..0dd9e6c976ac 100644\n--- a/fs/smb/server/mgmt/user_session.c\n+++ b/fs/smb/server/mgmt/user_session.c\n@@ -391,6 +391,7 @@ void ksmbd_session_destroy(struct ksmbd_session *sess)\n \tfree_channel_list(sess);\n \tkfree(sess->Preauth_HashValue);\n \tksmbd_release_id(&session_ida, sess->id);\n+\tida_destroy(&sess->tree_conn_ida);\n \tkfree(sess);\n }\n \n@@ -665,6 +666,8 @@ static struct ksmbd_session *__session_create(int protocol)\n \tif (!sess)\n \t\treturn NULL;\n \n+\tida_init(&sess->tree_conn_ida);\n+\n \tif (ksmbd_init_file_table(&sess->file_table))\n \t\tgoto error;\n \n@@ -684,8 +687,6 @@ static struct ksmbd_session *__session_create(int protocol)\n \tif (ret)\n \t\tgoto error;\n \n-\tida_init(&sess->tree_conn_ida);\n-\n \tdown_write(&sessions_table_lock);\n \thash_add(sessions_table, &sess->hlist, sess->id);\n \tup_write(&sessions_table_lock);\n", "prefixes": [ "1/2" ] }
