Tue, 20 Oct 2026 04:09:10 +0200

Merge tag 'namespace-7.4-rc1.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfsPull namespace updates from Christian Brauner: - Reject uid_map, gid_map and projid_map values that don't fit in a u32. map_write() parsed with simple_strtoul() and truncated modulo 2^32 on 64-bit so "4294967301 1000 1" was installed as "5 1000 1" without an error. Each field is parsed with kstrtou32() now and selftests cover the out-of-range, negative and in-range cases. This isn't a security fix. The truncated values were valid ids and every later check still applied to them. - Annotate struct uid_gid_map's forward and reverse pointers with __counted_by_ptr and add a KUnit suite for inserting and sorting extents. insert_extent() wrote to forward[nr_extents] before bumping the count which the annotation flags, so it bumps first now. Two follow-up fixes rename the now global helpers to uid_gid_map_insert_extent() and uid_gid_map_sort(), since the btrfs self-tests have their own insert_extent(), and guard the declarations on CONFIG_KUNIT. - Drop the BUG_ON() NULL checks in copy_mnt_ns() and copy_utsname(). create_new_namespaces() always passes a valid pointer and the other copy_*_ns() helpers don't check either. - Remove a dead key_put() on the create_user_ns() error path.* tag 'namespace-7.4-rc1.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: selftests/namespaces: add uid_map/gid_map range tests userns: reject uid_map/gid_map values that do not fit in u32 userns: declare the KUnit-visible helpers whenever KUnit is enabled userns: rename insert_extent() and sort_idmaps() userns: Add KUnit test suite for uid_gid_map userns: Add __counted_by_ptr attribute to struct uid_gid_map fs: namespace: drop BUG_ON() in copy_mnt_ns() uts: drop BUG_ON() in copy_utsname() userns: remove dead key_put() on the create_user_ns() error path List of files: /linux/kernel/tests/.kunitconfig

f6f1a2496ba5dcc076d7fb7aa329887cd6ae55fa - userns: Add KUnit test suite for uid_gid_map

Wed, 09 Sep 2026 00:27:30 +0200

userns: Add KUnit test suite for uid_gid_mapAdd a KUnit test suite to verify the insertion and sorting of mappingsin struct uid_gid_map. This test suite validates both base extentinsertion (<= 5 mappings) and extended extent insertion (> 5 mappings,which triggers the allocation of the forward and reverse pointers).This is especially useful for verifying that the __counted_by_ptrattribute added to 'forward' and 'reverse' pointers works correctlywithout causing any runtime bounds-checking panics or traps.Signed-off-by: Bill Wendling Link: https://patch.msgid.link/20260908222734.3048684-2-morbo@google.comTested-by: Bradley Morgan Reviewed-by: Bradley Morgan Signed-off-by: Christian Brauner (Amutable) List of files: /linux/kernel/tests/.kunitconfig
