ERROR::INODE-UPROBES(7stap)ERROR::INODE-UPROBES(7stap)NAMEerror::inode-uprobes - limitations of inode-uprobes
DESCRIPTION
The uprobes kernel facility introduced in Linux 3.5 aims to supplant
the earlier out-of-tree utrace patch to enable user-space probing.
There have been some functional limitations in inode-uprobes that pre‐
clude some systemtap constructs. Over time, we hope these regressions
will be corrected.
function.return probes
process.function().return probes require "return-probes" or
"uretprobes" functionality, which was not implemented in the
builtin inode-uprobes until kernel 3.10. If you cannot upgrade
your kernel, consider using process.statement() probes placed on
source line numbers at the function's return statements.
function.statement.absolute probes
In utrace-equipped kernels, systemtap made it possible to
address probes by literal addresses in the process virtual mem‐
ory address space. The new inode-uprobes does not have this
capability.
