Historically tty->pgrp and friends were pid_t and the code "knew" they were safe. The change to pid structs opened up a few races and the removal of the BKL in places made them quite hittable.

Set TIF_SIGPENDING in set_restore_sigmask. This lets arch code take TIF_RESTORE_SIGMASK out of the set of bits that will be noticed on return to user mode. On some machines those bits are scarce, and we can free this unneeded one up for other uses. It is probably the case that TIF_SIGPENDING is always set anyway everywhere set_restore_sigmask() is used.

2008-04-30signals: fix /sbin/init protection from unwanted signalsOleg Nesterov1-0/+2
The global init has a lot of long standing problems with the unhandled fatal signals. - The "is_global_init(current)" check in get_signal_to_deliver() protects only the main thread. Sub-thread can dequee the fatal signal and shutdown the whole thread group except the main thread. If it dequeues SIGSTOP /sbin/init will be stopped, this is not right too. Note that we can't use is_global_init(->group_leader), this breaks exec and this can't solve other problems we have. - Even if afterwards ignored, the fatal signals sets SIGNAL_GROUP_EXIT on delivery. This breaks exec, has other bad implications, and this is just wrong. Introduce the new SIGNAL_UNKILLABLE flag to fix these problems. It also helps to solve some other problems addressed by the subsequent patches. Currently we use this flag for the global init only, but it could also be used by kthreads and (perhaps) by the sub-namespace inits. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Acked-by: "Eric W.

This is a bit silly, because both are just trivial helpers on top of do_send_sigqueue() and because the we pass the unused .si_signo parameter. Kill them both, rename do_send_sigqueue() to send_sigqueue(), and export it.

2008-04-30signals: re-assign CLD_CONTINUED notification from the sender to recieverOleg Nesterov1-0/+6
Based on discussion with Jiri and Roland. In short: currently handle_stop_signal(SIGCONT, p) sends the notification to p->parent, with this patch p itself notifies its parent when it becomes running. handle_stop_signal(SIGCONT) has to drop ->siglock temporary in order to notify the parent with do_notify_parent_cldstop(). This leads to multiple problems: - as Jiri Kosina pointed out, the stopped task can resume without actually seeing SIGCONT which may have a handler. - we race with another sig_kernel_stop() signal which may come in that window. - we race with sig_fatal() signals which may set SIGNAL_GROUP_EXIT in that window. - we can't avoid taking tasklist_lock() while sending SIGCONT. With this patch handle_stop_signal() just sets the new SIGNAL_CLD_CONTINUED flag in p->signal->flags and returns. The notification is sent by the first task which returns from finish_stop() (there should be at least one) or any other signalled thread from get_signal_to_deliver(). This is a user-visible change. Say, currently kill(SIGCONT, stopped_child) can't return without seeing SIGCHLD, with this patch SIGCHLD can be delayed unpredictably. Another difference is that if the child is ptraced by another process, CLD_CONTINUED may be delivered to ->real_parent after ptrace_detach() while currently it always goes to the tracer which doesn't actually need this notification. Hopefully not a problem. The patch asks for the futher obvious cleanups, I'll send them separately.

2008-04-30pxafb: introduce register independent LCD connection type for pxafberic miao1-0/+44
Reasons: 1. straight forward: the name "LCD_COLOR_DSTN_16BPP" is much better than "LCCR0_Pas | LCCR0_Color | LCCR0_Dual" 2. by defining LCD connection types as constants, it allows only valid possibilities 3. by removing the dependency of register bits definitions, those can be later moved into the body of pxafb.c, instead of having a regs-lcd.h around Currently, only lubbock, mainstone, zylonite and littleton have been modified to support these types (see coming patches after this). Other platforms are encouraged to change their way describing the LCD controller connections. Signed-off-by: eric miao <eric.miao@marvell.com> Cc: "Antonino A.

This is part of the effort moving peripheral registers outside of pxa-regs.h, and using ioremap() make it possible the same IP can be re-used on different processors with different registers space As a result, the fixed mapping in pxa_map_io() is removed. The regs-lcd.h can actually moved to where closer to pxafb.c but some of its bit definitions are directly used by various platform code, though this is not a good style.

2008-04-29ext4: Fix race between migration and mmap writeAneesh Kumar K.V1-0/+1
Fail migrate if we allocated new blocks via mmap write. If we write to holes in the file via mmap, we end up allocating new blocks. This block allocation happens without taking inode->i_mutex. Since migrate is protected by i_mutex and migrate expects that no new blocks get allocated during migrate, fail migrate if new blocks get allocated. We can't take inode->i_mutex in the mmap write path because that would result in a locking order violation between i_mutex and mmap_sem. Also adding a separate rw_sempahore for protection is really high overhead for a rare operation such as migrate.

spin_is_locked() doesn't work on UP without spinlock debugging. Make it safer and just return 1 on UP, so we don't get false positives. The plan is to kill this debug function during the -rc cycle.

2008-04-29block: fix queue locking verificationLinus Torvalds1-2/+8
The new queue_flag_set/clear() functions verify that the queue is locked, but in doing so they will actually instead oops if the queue lock hasn't been initialized at all. So fix the lock debug test to consider the "no lock" case to be unlocked. This way you get a nice WARN_ON_ONCE() instead of a fatal oops. Bug introduced by commit 75ad23bc0fcb4f992a5d06982bf0857ab1738e9e ("block: make queue flags non-atomic").
