* [PATCH] make cap_ptrace enforce PTRACE_TRACME checksChris Wright2006-03-25
| | | | | | | | | | | | | | | | PTRACE_TRACEME doesn't have proper capabilities validation when parent is less privileged than child. Issue pointed out by Ram Gupta <ram.gupta5@gmail.com>. Note: I haven't identified a strong security issue, and it's a small ABI change that could break apps that rely on existing behaviour (which allows parent that is less privileged than child to ptrace when child does PTRACE_TRACEME).

* [PATCH] POLLRDHUP/EPOLLRDHUP handling for half-closed devices notificationsDavide Libenzi2006-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the half-closed devices notifiation, by adding a new POLLRDHUP (and its alias EPOLLRDHUP) bit to the existing poll/select sets. Since the existing POLLHUP handling, that does not report correctly half-closed devices, was feared to be changed, this implementation leaves the current POLLHUP reporting unchanged and simply add a new bit that is set in the few places where it makes sense. The same thing was discussed and conceptually agreed quite some time ago: http://lkml.org/lkml/2003/7/12/116 Since this new event bit is added to the existing Linux poll infrastruture, even the existing poll/select system calls will be able to use it. As far as the existing POLLHUP handling, the patch leaves it as is. The pollrdhup-2.6.16.rc5-0.10.diff defines the POLLRDHUP for all the existing archs and sets the bit in the six relevant files. The other attached diff is the simple change required to sys/epoll.h to add the EPOLLRDHUP definition. There is "a stupid program" to test POLLRDHUP delivery here: http://www.xmailserver.org/pollrdhup-test.c It tests poll(2), but since the delivery is same epoll(2) will work equally.

* [PATCH] IRQ: prevent enabling of previously disabled interruptBryan Holty2006-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | This fix prevents re-disabling and enabling of a previously disabled interrupt. On an SMP system with irq balancing enabled; If an interrupt is disabled from within its own interrupt context with disable_irq_nosync and is also earmarked for processor migration, the interrupt is blindly moved to the other processor and enabled without regard for its current "enabled" state. If there is an interrupt pending, it will unexpectedly invoke the irq handler on the new irq owning processor (even though the irq was previously disabled) The more intuitive fix would be to invoke disable_irq_nosync and enable_irq, but since we already have the desc->lock from __do_IRQ, we cannot call them directly. Instead we can use the same logic to disable and enable found in disable_irq_nosync and enable_irq, with regards to the desc->depth. This now prevents a disabled interrupt from being re-disabled, and more importantly prevents a disabled interrupt from being incorrectly enabled on a different processor.

| | | | | | | | | | | | | | | | There were a number of conflicting naming schemes used in the v9fs project. The directory was fs/9p, but MAINTAINERS and Documentation referred to v9fs. The module name itself was 9p2000, and the file system type was 9P. This patch attempts to clean that up, changing all references to 9p in order to match the directory name. We'll also start using 9p instead of v9fs as our patch prefix.

| | | | | | | | | | | | | | | | | | | | | Remove the assumption that driver_register() returns the number of devices bound to the driver. In fact, it returns zero for success or a negative error value. zorro_module_init() used the device count to automatically unregister and unload drivers that found no devices. That might have worked at one time, but has been broken for some time because zorro_register_driver() returned either a negative error or a positive count (never zero). So it could only unregister on failure, when it's not needed anyway. This functionality could be resurrected in individual drivers by counting devices in their .probe() methods.

Also make the warning message more friendly by printing the name of the initcall function. Also drop the KERN_DEBUG from the initcall_debug message.

* [PATCH] inotify: lock avoidance with parent watch status in dentryNick Piggin2006-03-25
| | | | | | | | | | | | | | | | | | | | | | Previous inotify work avoidance is good when inotify is completely unused, but it breaks down if even a single watch is in place anywhere in the system. Robin Holt notices that udev is one such culprit - it slows down a 512-thread application on a 512 CPU system from 6 seconds to 22 minutes. Solve this by adding a flag in the dentry that tells inotify whether or not its parent inode has a watch on it. Event queueing to parent will skip taking locks if this flag is cleared. Setting and clearing of this flag on all child dentries versus event delivery: this is no in terms of race cases, and that was shown to be equivalent to always performing the check. The essential behaviour is that activity occuring _after_ a watch has been added and _before_ it has been removed, will generate events.

* [PATCH] Add lookup_instantiate_filp usage warningOleg Drokin2006-03-25
| | | | | | | | | | | | | I think it would be nice to put an usage warning in header of lookup_instantiate_filp() to indicate it is unsafe to use it on anything but regular files (even that is potentially unsafe, but there your ->open() is usually in your hands anyway), so that others won't fall into the same trap I did.

* [PATCH] Introduce FMODE_EXEC file flagOleg Drokin2006-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | Introduce FMODE_EXEC file flag, to indicate that file is being opened for execution. This is useful for distributed filesystems to maintain consistent behavior for returning ETXTBUSY when opening for write and execution happens on different nodes. akpm: Needed by Lustre at present. I assume their objective to to work towards being able to install Lustre on an unmodified distro kernel, which seems sane. It should have zero runtime cost. Trond and Chuck indicate that NFS4 can probably use this too, for the same thing. Steven says it's also on the GFS todo list.

* [PATCH] reiserfs: reiserfs_file_write() will lose error code when a 0-length ↵Jeff Mahoney2006-03-25
| | | | | | | | | | | | | | | | | | | write occurs w/ O_SYNC When an error occurs in reiserfs_file_write before any data is written, and O_SYNC is set, the return code of generic_osync_write will overwrite the error code, losing it. This patch ensures that generic_osync_inode() doesn't run under an error condition, losing the error. This duplicates the logic from generic_file_buffered_write().
