- BZ#919101, BZ#1056828
- This update adds several new command-line options: "-y" to print file descriptor paths, "-P" to filter system calls based on the file descriptor paths, and "-I" to control how interactive strace is.A new command-line utility, strace-log-merge, has been added. This utility can be used to merge timestamped strace output into a single file.The strace utility now uses optimized interfaces to extract data from the traced process for better performance.The strace utility now provides improved support for decoding of arguments for various system calls. In addition, a number of new system calls are supported.
- Previously, the strace utility incorrectly handled the return value from the shmat() system call. Consequently, the return value displayed was "?" instead of the address of the attached shared memory segment. This bug has been fixed, and strace now displays the correct return value for the shmat() system calls.
