Hi All,
With ofed 1.5.1 (and it appears to be the case in prior versions as
well), I see the following files created under /sys which are world
writeable
# find /sys -type f -perm 222 -ls
6834 0 --w--w--w- 1 root root 0 Jun 3 14:50
/sys/class/infiniband/mlx4_0/diag_counters/clear_diag
8344 0 --w--w--w- 1 root root 4096 Jun 3 14:43
/sys/class/net/ib1/delete_child
8343 0 --w--w--w- 1 root root 4096 Jun 3 14:43
/sys/class/net/ib1/create_child
8295 0 --w--w--w- 1 root root 4096 Jun 3 14:43
/sys/class/net/ib0/delete_child
8294 0 --w--w--w- 1 root root 0 Jun 3 14:39
/sys/class/net/ib0/create_child
6017 0 --w--w--w- 1 root root 4096 Jun 3 14:43
/sys/devices/pci0000:00/0000:00:04.0/0000:13:00.0/port_trigger
ib0 & ib1 are slave interfaces corresponding to the 2 ports on a
ConnectX HCA.
At least the create_child & delete_child files appear to be dangerous to
leave as world writeable because they result in resources allocations.
I'm not sure about the others. Do these have to be world writeable?
