| Florian Weimer | 2022-06-08 15:02:08 UTC | Summary | glibc: Incorrect results of POWER9-optimized strncpy | glibc: Incorrect results of POWER9-optimized strncpy [rhel-8.7.0] |
| Florian Weimer | 2022-06-13 14:40:46 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 POWER9 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. | ||
