hi,
this is RFC patchset on 2 tools that our customer wants
and perhaps would like to see them upstream.
The sofdsnoop traces FDs passed through unix sockets:
# ./sofdsnoop
ACTION TID COMM SOCKET FD NAME
SEND 2576 Web Content 24:socket:[39763] 51
/dev/shm/org.mozilla.ipc.2576.23874
RECV 2576 Web Content 49:socket:[809997] 51
SEND 2576 Web Content 24:socket:[39763] 58 N/A
...
The shmsnoop tool to trace System V shared memory syscalls:
# ./shmsnoop.py
PID COMM SYS RET ARGs
19813 server SHMGET 10000 key: 0x78020001, size: 20,
shmflg: 0x3b6 (IPC_CREAT|0666)
19813 server SHMAT 7f1cf8b1f000 shmid: 0x10000, shmaddr: 0x0,
shmflg: 0x0
19816 client SHMGET 10000 key: 0x78020001, size: 20,
shmflg: 0x1b6 (0666)
...
They are still under testing/review, but I'd like to
have some upstream folks opinions on these.
thanks,
jirka
