Levin" This patch has been added to the 4.1 stable tree. If you have any objections, please let us know. =============== [ Upstream commit f0b22d1bb2a37a665a969e95785c75a4f49d1499 ] Do not load one entry beyond the end of the syscall table when the syscall number of a traced process equals to __NR_Linux_syscalls. Similar bug with regular processes was fixed by commit 3bb457af4fa8 ("[PARISC] Fix bug when syscall nr is __NR_Linux_syscalls"). This bug was found by strace test suite.
