* x86: kprobes: add kprobes smoke tests that run on bootAnanth N Mavinakayanahalli2008-01-301-0/+12
| | | | | | | | | | | | | | | | | | | | | Here is a quick and naive smoke test for kprobes. This is intended to just verify if some unrelated change broke the *probes subsystem. It is self contained, architecture agnostic and isn't of any great use by itself. This needs to be built in the kernel and runs a basic set of tests to verify if kprobes, jprobes and kretprobes run fine on the kernel. In case of an error, it'll print out a message with a "BUG" prefix. This is a start; we intend to add more tests to this bucket over time. Thanks to Jim Keniston and Masami Hiramatsu for comments and suggestions. Tested on x86 (32/64) and powerpc.

| * [LIB] pcounter : unline too big functionsEric Dumazet2008-01-281-5/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before pushing pcounter to Linus tree, I would like to make some adjustments. Goal is to reduce kernel text size, by unlining too big functions. When a pcounter is bound to a statically defined per_cpu variable, we define two small helpers functions. (No more folding function using the fat for_each_possible_cpu(cpu) ... ) static DEFINE_PER_CPU(int, NAME##_pcounter_values); static void NAME##_pcounter_add(struct pcounter *self, int val) { __get_cpu_var(NAME##_pcounter_values) += val; } static int NAME##_pcounter_getval(const struct pcounter *self, int cpu) { return per_cpu(NAME##_pcounter_values, cpu); } Fast path is therefore unchanged, while folding/alloc/free is now unlined.

* SG: work with the SCSI fixed maximum allocations.James Bottomley2008-01-281-14/+27
| | | | | | | | | | | | SCSI sg table allocation has a maximum size (of SCSI_MAX_SG_SEGMENTS, currently 128) and this will cause a BUG_ON() in SCSI if something tries an allocation over it. This patch adds a size limit to the chaining allocator to allow the specification of the maximum allocation size for chaining, so we always chain in units of the maximum SCSI allocation size.

* Kobject: auto-cleanup on final unrefKay Sievers2008-01-242-74/+107
| | | | | | | | | | | | | | | | We save the current state in the object itself, so we can do proper cleanup when the last reference is dropped. If the initial reference is dropped, the object will be removed from sysfs if needed, if an "add" event was sent, "remove" will be send, and the allocated resources are released. This allows us to clean up some driver core usage as well as allowing us to do other such changes to the rest of the kernel.

* Kobject: drop child->parent ref at unregistrationAlan Stern2008-01-241-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1015) reverts changes that were made to the driver core about four years ago. The intent back then was to avoid certain kinds of invalid memory accesses by leaving kernel objects allocated as long as any of their children were still allocated. The original and correct approach was to wait only as long as any children were still _registered_; that's what this patch reinstates. This fixes a problem in the SCSI core made visible by the class_device to regular device conversion: A reference loop (scsi_device holds reference to request_queue, which is the child of a gendisk, which is the child of the scsi_device) prevents the data structures from being released, even though they are deregistered okay. It's possible that this change will cause a few bugs to surface, things that have been hidden for several years. They can be fixed easily enough by having the child device take an explicit reference to the parent whenever needed.

| | | | | | | | | | | | | kobject_init should not be grabing any references, but only initializing the object.

* lib: proportion: fix underflow in prop_norm_percpu()Peter Zijlstra2007-12-231-21/+16
| | | | | | | | | | | | | | | | | | | | | Zhe Jiang noticed that its possible to underflow pl->events in prop_norm_percpu() when the value returned by percpu_counter_read() is less than the error on that read and the period delay > 1. In that case half might not trigger the batch increment and the value will be identical on the next iteration, causing the same half to be subtracted again and again. Fix this by rewriting the division as a single subtraction instead of a subtraction loop and using percpu_counter_sum() when the value returned by percpu_counter_read() is smaller than the error. The latter is still needed if we want pl->events to shrink properly in the error region.

* sched: mark rwsem functions as __sched for wchan/profilingLivio Soares2007-12-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This following commit http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=fdf8cb0909b531f9ae8f9b9d7e4eb35ba3505f07 un-inlined a low-level rwsem function, but did not mark it as __sched. The result is that it now shows up as thread wchan (which also affects /proc/profile stats). The following simple patch fixes this by properly marking rwsem_down_failed_common() as a __sched function. Also in this patch, which is up for discussion, marks down_read() and down_write() proper as __sched. For profiling, it is pretty much useless to know that a semaphore is beig help - it is necessary to know _which_ one. By going up another frame on the stack, the information becomes much more useful. In summary, the below change to lib/rwsem.c should be applied; the changes to kernel/rwsem.c could be applied if other kernel hackers agree with my proposal that down_read()/down_write() in the profile is not enough.

* | hexdump: don't print bytes with bit 7 setRandy Dunlap2007-11-291-1/+2
| | | | | | | | | | | | | | | | | | | | | | As Herbert Xu pointed out, bytes (chars) with bit 7 (0x80) set are true with isprint() but they may not be isascii() but be Unicode instead, so don't try to print them in hex dumps.
