Florian Weimer 2022-06-13 14:40:35 UTC Doc Text Cause: The strncpy function uses the wrong register for writing NUL padding.

Consequence: Uninitialized register content is written to the output buffer.

Fix: The correct register is now used as the source for the NUL bytes.

Result: The tail end of the output buffer is now correctly overwritten with NUL bytes.

Doc Text Cause: The ppc64le strncpy function uses the wrong register for writing NUL padding.

Consequence: Uninitialized register content is written to the output buffer.

Fix: The correct register is now used as the source for the NUL bytes.

Result: The
.POWER9-optimized strncpy no longer gives incorrect results

Previously, the POWER9 strncpy function did not use the correct register as the source of the NUL bytes for padding. Consequently
Doc Text tail end of the output buffer is now correctly overwritten with NUL bytes. , the output buffer contained uninitialized register content instead of the NUL padding. With this update, strncpy function has been fixed, and the tail end of the output buffer is now correctly padded with NUL bytes.
