2009-03-24Dynamic debug: allow simple quoting of wordsGreg Banks1-20/+33
Allow simple quoting of words in the dynamic debug control language. This allows more natural specification when using the control language to match against printk formats, e.g #echo -n 'format "Setting node for non-present cpu" +p' > /mnt/debugfs/dynamic_debug/control instead of #echo -n 'format Setting\040node\040for\040non-present\040cpu +p' > /mnt/debugfs/dynamic_debug/control Adjust the dynamic debug documention to describe that and provide a new example. Adjust the existing examples in the documentation to reflect the current whitespace escaping behaviour when reading the control file. Fix some minor documentation trailing whitespace.

2009-03-24dynamic debug: combine dprintk and dynamic printkJason Baron4-416/+758
This patch combines Greg Bank's dprintk() work with the existing dynamic printk patchset, we are now calling it 'dynamic debug'. The new feature of this patchset is a richer /debugfs control file interface, (an example output from my system is at the bottom), which allows fined grained control over the the debug output. The output can be controlled by function, file, module, format string, and line number. for example, enabled all debug messages in module 'nf_conntrack': echo -n 'module nf_conntrack +p' > /mnt/debugfs/dynamic_debug/control to disable them: echo -n 'module nf_conntrack -p' > /mnt/debugfs/dynamic_debug/control A further explanation can be found in the documentation patch.

2009-03-24kobject: don't block for each kobject_ueventArjan van de Ven1-1/+1
Right now, the kobject_uevent code blocks for each uevent that's being generated, due to using (for hystoric reasons) UHM_WAIT_EXEC as flag to call_usermode_helper(). Specifically, the effect is that each uevent that is being sent causes the code to wake up keventd, then block until keventd has processed the work. Needless to say, this happens many times during the system boot. This patches changes that to UHN_NO_WAIT (brilliant name for a constant btw) so that we only schedule the work to fire the uevent message, but do not wait for keventd to process the work. This removes one of the bottlenecks during boot; each one of them is only a small effect, but the sum of them does add up. [Note, distros that need this are broken, they should be setting CONFIG_UEVENT_HELPER_PATH to "", that way this code path will never be excuted at all -- gregkh] Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-03-24Driver core: implement uevent suppress in kobjectMing Lei1-0/+7
This patch implements uevent suppress in kobject and removes it from struct device, based on the following ideas: 1,Uevent sending should be one attribute of kobject, so suppressing it in kobject layer is more natural than in device layer. By this way, we can do it for other objects embedded with kobject. 2,It may save several bytes for each instance of struct device.(On my omap3(32bit ARM) based box, can save 8bytes per device object) This patch also introduces dev_set|get_uevent_suppress() helpers to set and query uevent_suppress attribute in case to help kobject as private part of struct device in future.

2009-03-12bitmap: fix end condition in bitmap_find_free_regionLinus Torvalds1-8/+8
Guennadi Liakhovetski noticed that the end condition for the loop in bitmap_find_free_region() is wrong, and the "return if error" was also using the wrong conditional that would only trigger if the bitmap was an exact multiple of the allocation size, which is not necessarily the case with dma_alloc_from_coherent(). Such a failure would end up in bitmap_find_free_region() accessing beyond the end of the bitmap.

We moved the netlink attribute support from net to lib in order for it to be available for general consumption. However, parts of the code (the bits that we don't need :) really depends on NET because the target object is sk_buff. This patch fixes this by wrapping them in CONFIG_NET.

2009-03-10idr: make idr_remove_all() do removal -before- free_layer()Paul E. McKenney1-1/+1
Fix a problem in the IDR system, where an idr_remove_all() hands a data element to call_rcu() (via free_layer()) before making that data element inaccessible to new readers. This is very bad, and results in readers still having a reference to this data element at the end of the grace period. Tests on large machines that concurrently map and unmap user-space memory within the same multithreaded process result in crashes within about five minutes. Applying this patch increases the kernel's longevity to the three-to-eight-hour range. There appear to be other similar problems in idr_get_empty_slot() and sub_remove(), but I fixed the easy one in idr_remove_all() first. It is therefore no surprise that failures still occur.

2009-02-05netlink: change return-value logic of netlink_broadcast()Pablo Neira Ayuso1-0/+3
Currently, netlink_broadcast() reports errors to the caller if no messages at all were delivered: 1) If, at least, one message has been delivered correctly, returns 0. 2) Otherwise, if no messages at all were delivered due to skb_clone() failure, return -ENOBUFS. 3) Otherwise, if there are no listeners, return -ESRCH. With this patch, the caller knows if the delivery of any of the messages to the listeners have failed: 1) If it fails to deliver any message (for whatever reason), return -ENOBUFS. 2) Otherwise, if all messages were delivered OK, returns 0. 3) Otherwise, if no listeners, return -ESRCH. In the current ctnetlink code and in Netfilter in general, we can add reliable logging and connection tracking event delivery by dropping the packets whose events were not successfully delivered over Netlink. Of course, this option would be settable via /proc as this approach reduces performance (in terms of filtered connections per seconds by a stateful firewall) but providing reliable logging and event delivery (for conntrackd) in return. This patch also changes some clients of netlink_broadcast() that may report ENOBUFS errors via printk. This error handling is not of any help. Instead, the userspace daemons that are listening to those netlink messages should resync themselves with the kernel-side if they hit ENOBUFS. BTW, netlink_broadcast() clients include those that call cn_netlink_send(), nlmsg_multicast() and genlmsg_multicast() since they internally call netlink_broadcast() and return its error value.

2009-01-15lib/idr.c: use kmem_cache_zalloc() for the idr_layer cacheAndrew Morton1-8/+2
David points out that the idr_remove_all() function returns unused slabs to the kmem cache, but needs to zero them first or else they will be uninitialized upon next use. This causes crashes which have been observed in the firewire subsystem. He fixed this by zeroing the object before freeing it in idr_remove_all(). But we agree that simply removing the constructor and zeroing the object at allocation time is simpler than relying upon slab constructor machinery and might even be faster. This problem was introduced by "idr: make idr_remove rcu-safe" (commit cf481c20c476ad2c0febdace9ce23f5a4db19582), which was first released in 2.6.27. There are no known codesites which trigger this bug in 2.6.27 or 2.6.28. The post-2.6.28 firewire changes are the only known triggerer. There might of course be not-yet-discovered triggerers in 2.6.27 and 2.6.28, and there might be out-of-tree triggerers which are added to those kernel versions. I'll let the -stable guys decide whether they want to backport this fix.

2009-01-10rbtree: add const qualifier to some functionsArtem Bityutskiy1-6/+6
The 'rb_first()', 'rb_last()', 'rb_next()' and 'rb_prev()' calls take a pointer to an RB node or RB root. They do not change the pointed objects, so add a 'const' qualifier in order to make life of the users of these functions easier. Indeed, if I have my own constant pointer &const struct my_type *p, and I call 'rb_next(&p->rb)', I get a GCC warning: warning: passing argument 1 of ‘rb_next’ discards qualifiers from pointer target type Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
