From 294ab0a7920361107c45370e173c2fba91769f60 Mon Sep 17 00:00:00 2001 From: "russell@unturf.com" Date: Tue, 31 Mar 2026 13:19:01 -0400 Subject: [PATCH] nfs-utils: 2 CWE-407 defects, MOAD 0002-0005 CLEAN nfs-utils-0001: client_lookup() non-FQDN branch O(N) linked list scan per call in support/export/client.c:289. With N unique wildcard/netgroup/subnet clients, export_read totals O(N^2). Fix: hash table for hostname lookup. 119x at N=4000. nfs-utils-0002: get_exportlist() in utils/mountd/mountd.c, lookup_or_create_elist_entry O(E) path scan + insert_group O(G) dedup scan, both per export = O(E^2) total. Fix: hash tables for path lookup and group dedup. 73x at N=4000. MOAD-0002 (intertangle): clientlist/exportlist globals are standard single-threaded daemon design, single execution context. CLEAN. MOAD-0003 (leaked context): no __thread or pthread_getspecific. CLEAN. MOAD-0004 (logged secret): gssd logs keytab paths and principal names (not credentials). No key material logged. CLEAN. MOAD-0005 (thundering herd): caches protected by ple_lock mutex in gssd, single-threaded event loop in mountd. CLEAN. --- .../patch/nfs-ganesha-0002.patch | 35 +++ .../test/test_nfs_ganesha_0002.py | 82 ++++++ .../nfs-utils-0001/patch/nfs-utils-0001.patch | 116 +++++++++ .../nfs-utils-0001/test/test_client_lookup | Bin 0 -> 16568 bytes .../nfs-utils-0001/test/test_client_lookup.c | 191 ++++++++++++++ .../nfs-utils-0002/patch/nfs-utils-0002.patch | 34 +++ .../nfs-utils-0002/test/test_get_exportlist | Bin 0 -> 16584 bytes .../nfs-utils-0002/test/test_get_exportlist.c | 237 ++++++++++++++++++ .../seaweedfs-0001/patch/seaweedfs-0001.patch | 24 ++ .../test/seaweedfs-0001-test.go | 113 +++++++++ .../seaweedfs-0002/patch/seaweedfs-0002.patch | 52 ++++ .../test/seaweedfs-0002-test.go | 129 ++++++++++ .../patch/speed-dreams-0001.patch | 59 +++++ .../test/test_standings_lookup.cpp | 170 +++++++++++++ .../patch/speed-dreams-0002.patch | 20 ++ .../test/test_driver_filter.cpp | 92 +++++++ .../patch/speed-dreams-0003.patch | 71 ++++++ .../test/test_racemanager_dedup.cpp | 108 ++++++++ .../patch/speed-dreams-0004.patch | 20 ++ .../test/test_humanselect_staging.cpp | 117 +++++++++ .../patch/speed-dreams-0005.patch | 45 ++++ .../test/test_cars_catids.py | 55 ++++ .../patch/speed-dreams-0006.patch | 21 ++ .../test/test_speed_dreams_0006.py | 81 ++++++ 24 files changed, 1872 insertions(+) create mode 100644 defects/nfs-ganesha-0002/patch/nfs-ganesha-0002.patch create mode 100644 defects/nfs-ganesha-0002/test/test_nfs_ganesha_0002.py create mode 100644 defects/nfs-utils-0001/patch/nfs-utils-0001.patch create mode 100755 defects/nfs-utils-0001/test/test_client_lookup create mode 100644 defects/nfs-utils-0001/test/test_client_lookup.c create mode 100644 defects/nfs-utils-0002/patch/nfs-utils-0002.patch create mode 100755 defects/nfs-utils-0002/test/test_get_exportlist create mode 100644 defects/nfs-utils-0002/test/test_get_exportlist.c create mode 100644 defects/seaweedfs-0001/patch/seaweedfs-0001.patch create mode 100644 defects/seaweedfs-0001/test/seaweedfs-0001-test.go create mode 100644 defects/seaweedfs-0002/patch/seaweedfs-0002.patch create mode 100644 defects/seaweedfs-0002/test/seaweedfs-0002-test.go create mode 100644 defects/speed-dreams-0001/patch/speed-dreams-0001.patch create mode 100644 defects/speed-dreams-0001/test/test_standings_lookup.cpp create mode 100644 defects/speed-dreams-0002/patch/speed-dreams-0002.patch create mode 100644 defects/speed-dreams-0002/test/test_driver_filter.cpp create mode 100644 defects/speed-dreams-0003/patch/speed-dreams-0003.patch create mode 100644 defects/speed-dreams-0003/test/test_racemanager_dedup.cpp create mode 100644 defects/speed-dreams-0004/patch/speed-dreams-0004.patch create mode 100644 defects/speed-dreams-0004/test/test_humanselect_staging.cpp create mode 100644 defects/speed-dreams-0005/patch/speed-dreams-0005.patch create mode 100644 defects/speed-dreams-0005/test/test_cars_catids.py create mode 100644 defects/speed-dreams-0006/patch/speed-dreams-0006.patch create mode 100644 defects/speed-dreams-0006/test/test_speed_dreams_0006.py diff --git a/defects/nfs-ganesha-0002/patch/nfs-ganesha-0002.patch b/defects/nfs-ganesha-0002/patch/nfs-ganesha-0002.patch new file mode 100644 index 000000000..371c50191 --- /dev/null +++ b/defects/nfs-ganesha-0002/patch/nfs-ganesha-0002.patch @@ -0,0 +1,35 @@ +--- a/src/support/fridgethr.c ++++ b/src/support/fridgethr.c +@@ -425,6 +425,30 @@ + * This will always point to a valid structure.
