[PATCH v3 0/2] lib/idr: Fixes for infinite loop and memory leak

Posted by Josh Law 3 weeks, 4 days ago

This series includes two fixes for the IDR and IDA APIs, along with
their corresponding test cases as requested by reviewers.

1. Fix an infinite loop condition in idr_get_next() that occurs when
   iterating over an ID > INT_MAX.
2. Fix a memory leak in ida_alloc_range() where an intermediate
   allocated bitmap is not freed if a subsequent XArray insertion fails.

Both fixes update tools/testing/radix-tree/idr-test.c to ensure the
error paths are covered by the test suite.

Changes since v2:
- Added `idr-test.c` updates to both commits to formally test the fix conditions.
