    ptrace: ensure JOBCTL_STOP_SIGMASK is not zero after detach

    utrace authored torvalds committed
    This is the temporary simple fix for 3.2, we need more changes in this
    1. do_signal_stop() assumes that the running untraced thread in the
       stopped thread group is not possible. This was our goal but it is
       not yet achieved: a stopped-but-resumed tracee can clone the running
       thread which can initiate another group-stop.
       Remove WARN_ON_ONCE(!current->ptrace).
    2. A new thread always starts with ->jobctl = 0. If it is auto-attached
       and this group is stopped, __ptrace_unlink() sets JOBCTL_STOP_PENDING
       but JOBCTL_STOP_SIGMASK part is zero, this triggers WANR_ON(!signr)
       in do_jobctl_trap() if another debugger attaches.
       Change __ptrace_unlink() to set the artificial SIGSTOP for report.
       Alternatively we could change ptrace_init_task() to copy signr from
       current, but this means we can copy it for no reason and hide the
       possible similar problems.

    ptrace: partially fix the do_wait(WEXITED) vs EXIT_DEAD->EXIT_ZOMBIE …

    utrace authored torvalds committed
    	int main(void)
    		int pid, status;
    		pid = fork();
    		if (!pid) {
    			for (;;) {
    				if (!fork())
    					return 0;
    				if (waitpid(-1, &status, 0) < 0) {
    					printf("ERR!! wait: %m\n");
    					return 0;
    		assert(ptrace(PTRACE_ATTACH, pid, 0,0) == 0);
    		assert(waitpid(-1, NULL, 0) == pid);
    		assert(ptrace(PTRACE_SETOPTIONS, pid, 0,
    					PTRACE_O_TRACEFORK) == 0);
    		do {
    			ptrace(PTRACE_CONT, pid, 0, 0);
    			pid = waitpid(-1, NULL, 0);
    		} while (pid > 0);
    		return 1;
    It fails because ->real_parent sees its child in EXIT_DEAD state
    while the tracer is going to change the state back to EXIT_ZOMBIE
    in wait_task_zombie().
    The offending commit is 823b018 which moved the EXIT_DEAD check,
    but in fact we should not blame it. The original code was not
    correct as well because it didn't take ptrace_reparented() into
    account and because we can't really trust ->ptrace.
    This patch adds the additional check to close this particular
    race but it doesn't solve the whole problem. We simply can't
    rely on ->ptrace in this case, it can be cleared if the tracer
    is multithreaded by the exiting ->parent.
    I think we should kill EXIT_DEAD altogether, we should always
    remove the soon-to-be-reaped child from ->children or at least
    we should never do the DEAD->ZOMBIE transition. But this is too
    complex for 3.2.

    Revert "rtc: Expire alarms after the time is set."

    torvalds authored
    This reverts commit 93b2ec0.
    The call to "schedule_work()" in rtc_initialize_alarm() happens too
    early, and can cause oopses at bootup
    Neil Brown explains why we do it:
      "If you set an alarm in the future, then shutdown and boot again after
       that time, then you will end up with a timer_queue node which is in
       the past.
       When this happens the queue gets stuck.  That entry-in-the-past won't
       get removed until and interrupt happens and an interrupt won't happen
       because the RTC only triggers an interrupt when the alarm is "now".
       So you'll find that e.g.  "hwclock" will always tell you that
       'select' timed out.
       So we force the interrupt work to happen at the start just in case."
    and has a patch that convert it to do things in-process rather than with
    the worker thread, but right now it's too late to play around with this,
    so we just revert the patch that caused problems for now.

  9. [CIFS] default ntlmv2 for cifs mount delayed to 3.3

    Steve French authored
    Turned out the ntlmv2 (default security authentication)
    upgrade was harder to test than expected, and we ran
    out of time to test against Apple and a few other servers
    that we wanted to.  Delay upgrade of default security
    from ntlm to ntlmv2 (on mount) to 3.3.  Still works
    fine to specify it explicitly via "sec=ntlmv2" so this
    should be fine.

  10. cifs: fix bad buffer length check in coalesce_t2

    Jeff Layton authored Steve French committed
    The current check looks to see if the RFC1002 length is larger than
    CIFSMaxBufSize, and fails if it is. The buffer is actually larger than
    that by MAX_CIFS_HDR_SIZE.
    This bug has been around for a long time, but the fact that we used to
    cap the clients MaxBufferSize at the same level as the server tended
    to paper over it. Commit c974bef changed that however and caused this
    bug to bite in more cases.

    security: Fix security_old_inode_init_security() when CONFIG_SECURITY…

    jankara authored torvalds committed
    … is not set
    Commit 1e39f38 ("evm: fix build problems") makes the stub version
    of security_old_inode_init_security() return 0 when CONFIG_SECURITY is
    not set.
    But that makes callers such as reiserfs_security_init() assume that
    security_old_inode_init_security() has set name, value, and len
    arguments properly - but security_old_inode_init_security() left them
    uninitialized which then results in interesting failures.
    Revert security_old_inode_init_security() to the old behavior of
    returning EOPNOTSUPP since both callers (reiserfs and ocfs2) handle this
    just fine.
    [ Also fixed the S_PRIVATE(inode) case of the actual non-stub
      security_old_inode_init_security() function to return EOPNOTSUPP
      for the same reason, as pointed out by Mimi Zohar.
      It got incorrectly changed to match the new function in commit
      fb88c2b: "evm: fix security/security_old_init_security return
      code".   - Linus ]

    drivers/net/ethernet/freescale/fec.c:411:2: error: 'FEC_HASH_TABLE_LOW' undeclared (first use in this function)
    This is because fec.h uses CONFIG_SOC_IMX28 to determine the register
    layout of the core which makes sense since the MX23 does not have a fec.
    However, Kconfig uses the broader ARCH_MXS symbol and this way even
    makes the fec-driver default for MX23. Adapt Kconfig to use the more
    precise SOC_IMX28 as well.
