DESCRIPTION
uretprobe()
is an alternative to breakpoint instructions
for triggering return uprobe consumers.

are only made from the use-space trampoline provided by the kernel.
Calls from any other place result in a
SIGILL.
RETURN VALUE
The return value is architectur-specific.
ERRORS
- SIGILL
-
uretprobe()
was called by a use-space program.
VERSIONS
The behavior varies across systems.
STANDARDS

HISTORY
Linux 6.11.
uretprobe()
was initially introduced for the x86_64 architecture
where it was shown to be faster than breakpoint traps.
It might be extended to other architectures.
CAVEATS

exists only to allow the invocation of return uprobe consumers.
It should
never
be called directly.
