Hello, I discovered some irregularities regarding fakeinit functionality. The following program gives different output on host and vservers:
| int main(int argc, char *argv[]) | { | printf("%i\n", getsid(atoi(argv[1]))); | } On host: | # ./a.out 1 | 0 on VServer: | # chcontext --xid 100 --flag fakeinit ./a.out 1 | 7448 This issue causes unexpected behaviour with SysV's 'killall5' which will kill the init-process also. Btw, this test reveals a minor security leak: getsid(2) does not test if the pid is visible but gives out the correct result: | # chcontext --xid 100 --flag fakeinit ./a.out $$ | 10461 ('$$' expands to the pid of the bash invoking 'chcontext'). Ditto for getpgid(2). The used patch was vs1.9.5-rc4 on a 2.6.11.6 kernel.
