f786648 Paul Mackerras 27 August 2005, 23:40:01 UTC [PATCH] Remove race between con_open and con_close [ Same race and same patch also by Steven Rostedt <rostedt@goodmis.org> ] I have a laptop (G3 powerbook) which will pretty reliably hit a race between con_open and con_close late in the boot process and oops in vt_ioctl due to tty->driver_data being NULL. What happens is this: process A opens /dev/tty6; it comes into con_open() (drivers/char/vt.c) and assign a non-NULL value to tty->driver_data. Then process A closes that and concurrently process B opens /dev/tty6. Process A gets through con_close() and clears tty->driver_data, since tty->count == 1. However, before process A can decrement tty->count, we switch to process B (e.g. at the down(&tty_sem) call at drivers/char/tty_io.c line 1626). So process B gets to run and comes into con_open with tty->count == 2, as tty->count is incremented (in init_dev) before con_open is called. Because tty->count != 1, we don't set tty->driver_data. Then when the process tries to do anything with that fd, it oopses. The simple and effective fix for this is to test tty->driver_data rather than tty->count in con_open. The testing and setting of tty->driver_data is serialized with respect to the clearing of tty->driver_data in con_close by the console_sem. We can't get a situation where con_open sees tty->driver_data != NULL and then con_close on a different fd clears tty->driver_data, because tty->count is incremented before con_open is called. Thus this patch eliminates the race, and in fact with this patch my laptop doesn't oops.

729d70f Jan Blunck 27 August 2005, 18:07:52 UTC [PATCH] sg.c: fix a memory leak in devices seq_file implementation I know that scsi procfs is legacy code but this is a fix for a memory leak. While reading through sg.c I realized that the implementation of /proc/scsi/sg/devices with seq_file is leaking memory due to freeing the pointer returned by the next() iterator method. Since next() might return NULL or an error this is wrong. This patch fixes it through using the seq_files private field for holding the reference to the iterator object. Here is a small bash script to trigger the leak.

Then it will call copy_to_user(buf,&v_buf[*ppos],count); with obvious results (similar for ->write()).

36676bc James Bottomley 27 August 2005, 01:34:17 UTC [PATCH] Fix oops in sysfs_hash_and_remove_file() The problem arises if an entity in sysfs is created and removed without ever having been made completely visible. In SCSI this is triggered by removing a device while it's initialising. The problem appears to be that because it was never made visible in sysfs, the sysfs dentry has a null d_inode which oopses when a reference is made to it. The solution is simply to check d_inode and assume the object was never made visible (and thus doesn't need deleting) if it's NULL. (akpm: possibly a stopgap for 2.6.13 scsi problems.

This fixes problems with the VM allowing too many dirty pages because it overestimates the number of available RAM in a node. In extreme cases you can end up with all RAM filled with dirty pages which can lead to deadlocks and other nasty behaviour. This patch just tells the VM about the known holes from e820. Reserved (like the kernel text or mem_map) is still not taken into account, but that should be only a few percent error now. Small detail is that the flat setup uses the NUMA free_area_init_node() now too because it offers more flexibility.

d634cc1 Steve French 26 August 2005, 19:42:59 UTC [PATCH] Fix oops in fs/locks.c on close of file with pending locks The recent change to locks_remove_flock code in fs/locks.c changes how byte range locks are removed from closing files, which shows up a bug in cifs. The assumption in the cifs code was that the close call sent to the server would remove any pending locks on the server on this file, but that is no longer safe as the fs/locks.c code on the client wants unlock of 0 to PATH_MAX to remove all locks (at least from this client, it is not possible AFAIK to remove all locks from other clients made to the server copy of the file). Note that cifs locks are different from posix locks - and it is not possible to map posix locks perfectly on the wire yet, due to restrictions of the cifs network protocol, even to Samba without adding a new request type to the network protocol (which we plan to do for Samba 3.0.21 within a few months), but the local client will have the correct, posix view, of the lock in most cases. The correct fix for cifs for this would involve a bigger change than I would like to do this late in the 2.6.13-rc cycle - and would involve cifs keeping track of all unmerged (uncoalesced) byte range locks for each remote inode and scanning that list to remove locks that intersect or fall wholly within the range - locks that intersect may have to be reaquired with the smaller, remaining range.

Wether that driver should use kernel_power_off() instead is debatable and a post-2.6.13 decision. In the meantime, please commit that patch that fixes the driver for now.

3725822 Paul Jackson 24 August 2005, 11:15:10 UTC [PATCH] cpu_exclusive sched domains build fix As reported by Paul Mackerras <paulus@samba.org>, the previous patch "cpu_exclusive sched domains fix" broke the ppc64 build with CONFIC_CPUSET, yielding error messages: kernel/cpuset.c: In function 'update_cpu_domains': kernel/cpuset.c:648: error: invalid lvalue in unary '&' kernel/cpuset.c:648: error: invalid lvalue in unary '&' On some arch's, the node_to_cpumask() is a function, returning a cpumask_t. But the for_each_cpu_mask() requires an lvalue mask. The following patch fixes this build failure by making a copy of the cpumask_t on the stack.

d10689b Paul Jackson 23 August 2005, 08:04:27 UTC [PATCH] cpu_exclusive sched domains on partial nodes temp fix This keeps the kernel/cpuset.c routine update_cpu_domains() from invoking the sched.c routine partition_sched_domains() if the cpuset in question doesn't fall on node boundaries. I have boot tested this on an SN2, and with the help of a couple of ad hoc printk's, determined that it does indeed avoid calling the partition_sched_domains() routine on partial nodes. I did not directly verify that this avoids setting up bogus sched domains or avoids the oops that Hawkes saw. This patch imposes a silent artificial constraint on which cpusets can be used to define dynamic sched domains. This patch should allow proceeding with this new feature in 2.6.13 for the configurations in which it is useful (node alligned sched domains) while avoiding trying to setup sched domains in the less useful cases that can cause the kernel corruption and oops.

This is caused by unconditionally checking the IS and c1 bits from the FPU status word when they are not always relevant.

The C1 bit determines whether a stack fault is overflow or underflow and is only relevant when IS and IE are set.

005eca5 NeilBrown 22 August 2005, 20:11:08 UTC [PATCH] md: make sure resync gets started when array starts. We weren't actually waking up the md thread after setting MD_RECOVERY_NEEDED when assembling an array, so it is possible to lose a race and not actually start resync. So add a call to md_wakeup_thread, and while we are at it, remove all the "if (mddev->thread)" guards as md_wake_thread does its own checking.

4c5640c David Meybohm 22 August 2005, 20:11:08 UTC [PATCH] preempt race in getppid With CONFIG_PREEMPT && !CONFIG_SMP, it's possible for sys_getppid to return a bogus value if the parent's task_struct gets reallocated after current->group_leader->real_parent is read: asmlinkage long sys_getppid(void) { int pid; struct task_struct *me = current; struct task_struct *parent; parent = me->group_leader->real_parent; RACE HERE => for (;;) { pid = parent->tgid; #ifdef CONFIG_SMP { struct task_struct *old = parent; /* * Make sure we read the pid before re-reading the * parent pointer: */ smp_rmb(); parent = me->group_leader->real_parent; if (old != parent) continue; } #endif break; } return pid; } If the process gets preempted at the indicated point, the parent process can go ahead and call exit() and then get wait()'d on to reap its task_struct. When the preempted process gets resumed, it will not do any further checks of the parent pointer on !CONFIG_SMP: it will read the bad pid and return. So, the same algorithm used when SMP is enabled should be used when preempt is enabled, which will recheck ->real_parent in this case.
