[PATCH v2 0/4] perf probe, tracing/uprobes: Support probing at absolute address

Show all headers | View raw

The goal of these 4 patches is to allow perf probing at absolute address
for uprobes and kprobes. During the development several small problem in
'perf probe -l' is found and fixed.

Patch 1 has already acked by Masami Hiramatsu.

Patch 2 fixes a problem about zero address in perf side.

Patch 3 is the main patch of these 4. It allows following command:

 # perf probe /lib/x86_64-linux-gnu/libc-2.19.so 0xeb860

 Different from v1, no extra '+' is required.

Patch 4 is a kernel side patch which fixes a small problem in uprobe_event
that, if address is 0, uprobe_events reports '0x  (null)'. It is independent
from the other patches.

Wang Nan (4):
  perf probe: Prevent segfault when reading probe point with absolute
    address
  perf probe: Fix list result when address is zero
  perf probe: Support probing at absolute address
  tracing/uprobes: Do not print '0x  (null)' when offset is 0
