Hi,
I am trying to use setfsgid()/setfssid() calls to ensure proper access
check for linux users.
However if user is non-root then ibv_reg_mr() returns EACCESS. While I
am sure I am calling ibv_reg_mr()
as root user, not sure why it still returns EACCESS.
While going through libibverbs sources I realize EACCESS might be
returned by this call:
if (write(pd->context->cmd_fd, cmd, cmd_size) != cmd_size)
return errno;
Can anyone provide any insight into this behavior? Does calling these
systems calls in threads can affect
entire process? I checked /dev/infiniband/* has appropriate privileges.
Thanks & Regards,
Vinit.
