…MOS#2) Bug NASA-AMMOS#2: BSL_BundleCtx_WriteBTSD must call realloc callback before write Problem: - BSL_BundleCtx_WriteBTSD was calling the write callback directly without first ensuring the BTSD buffer was large enough - When ION creates extension blocks, they start with length=1 (placeholder) - BSL then attempted to write 82 bytes into the 1-byte buffer - This caused the ION realloc callback to be called during write, but write had already started with insufficient buffer space Root Cause: - BSL_BundleCtx_WriteBTSD (lines 131-137) immediately called: return HostDescriptorTable.block_write_btsd_fn(bundle, block_num, btsd_len); - No buffer size check or realloc call before writing - The write callback would fail when attempting to write beyond allocated space Fix: - Added realloc call before write in BSL_BundleCtx_WriteBTSD (lines 138-148) - Check if realloc callback is registered and btsd_len > 0 - Call block_realloc_btsd_fn to expand buffer to needed size - Return NULL if realloc fails (with error logging) - Only proceed to write if realloc succeeds Code: /* Ensure the BTSD buffer is large enough before writing */ if (btsd_len > 0 && HostDescriptorTable.block_realloc_btsd_fn) { int realloc_result = HostDescriptorTable.block_realloc_btsd_fn(bundle, block_num, btsd_len); if (realloc_result != 0) { BSL_LOG_ERR("Failed to realloc BTSD buffer: block=%llu size=%zu result=%d", (unsigned long long)block_num, btsd_len, realloc_result); return NULL; } } Impact: - BSL now properly expands BTSD buffers before writing - BCB encryption can now write full encrypted payloads - BIB can write full HMAC signatures - This is part of a series of fixes enabling BSL BCB encryption in ION Related ION integration fixes (separate ION commits): - Bug NASA-AMMOS#3: Fix SDR violation in ion_bsl_ReallocBTSD - Bug NASA-AMMOS#4: Add payload block special handling in ion_bsl_ReallocBTSD Test: ION tests/bpsec/bpsec-all-multinode-test.bsl Status: BSL operations now succeed with this fix WIP: bpsec/bpsec-all-multinode-test.bsl not yet passing.
