| * [SCSI] block: add sg buffer copy helper functionsFUJITA Tomonori2008-04-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds new three helper functions to copy data between an SG list and a linear buffer. - sg_copy_from_buffer copies data from linear buffer to an SG list - sg_copy_to_buffer copies data from an SG list to a linear buffer When the APIs copy data from a linear buffer to an SG list, flush_kernel_dcache_page is called. It's not necessary for everyone but it's a no-op on most architectures and in general the API is not used in performance critical path.

The kgdb test suite is designed to be built into the kernel and not as a module because it uses a number of low level kernel and kgdb primitives which should not be exported externally. The kgdb test suite is designed as a KGDB I/O module which simulates the communications that a debugger would have with kgdb. The tests are broken up in to a line by line and referenced here as a "get" which is kgdb requesting input and "put" which is kgdb sending a response. The kgdb suite can be invoked from the kernel command line arguments system or executed dynamically at run time. The test suite uses the variable "kgdbts" to obtain the information about which tests to run and to configure the verbosity level. The following are the various characters you can use with the kgdbts= line: When using the "kgdbts=" you only choose one of the following core test types: A = Run all the core tests silently V1 = Run all the core tests with minimal output V2 = Run all the core tests in debug mode You can also specify optional tests: N## = Go to sleep with interrupts of for ## seconds to test the HW NMI watchdog F## = Break at do_fork for ## iterations S## = Break at sys_open for ## iterations NOTE: that the do_fork and sys_open tests are mutually exclusive. To invoke the kgdb test suite from boot you use a kernel start argument as follows: kgdbts=V1 kgdbwait Or if you wanted to perform the NMI test for 6 seconds and do_fork test for 100 forks, you could use: kgdbts=V1N6F100 kgdbwait The test suite can also be invoked at run time with: echo kgdbts=V1N6F100 > /sys/module/kgdbts/parameters/kgdbts Or as another example: echo kgdbts=V2 > /sys/module/kgdbts/parameters/kgdbts When developing a new kgdb arch specific implementation or using these tests for the purpose of regression testing, several invocations are required. 1) Boot with the test suite enabled by using the kernel arguments "kgdbts=V1F100 kgdbwait" ## If kgdb arch specific implementation has NMI use "kgdbts=V1N6F100 2) After the system boot run the basic test. echo kgdbts=V1 > /sys/module/kgdbts/parameters/kgdbts 3) Run the concurrency tests. It is best to use n+1 while loops where n is the number of cpus you have in your system. The example below uses only two loops. ## This tests break points on sys_open while [ 1 ] ; do find / > /dev/null 2>&1 ; done & while [ 1 ] ; do find / > /dev/null 2>&1 ; done & echo kgdbts=V1S10000 > /sys/module/kgdbts/parameters/kgdbts fg # and hit control-c fg # and hit control-c ## This tests break points on do_fork while [ 1 ] ; do date > /dev/null ; done & while [ 1 ] ; do date > /dev/null ; done & echo kgdbts=V1F1000 > /sys/module/kgdbts/parameters/kgdbts fg # and hit control-c Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

These messages are a regression compared with 2.6.24, which did not flood the syslog with them. The actual underlying problem was introduced in 2.6.23, when somebody made the string parsing no longer accept nul-terminated strings as a valid input to store_uevent(). Eg. "add\0" was valid prior to 2.6.23, where the code regressed to require "add" without the '\0'. This patch fixes the 2.6.23 / 2.6.24 regressions, by having the code once again tolerate the trailing '\0', if present. According to GregKH, this mainly affects older Ubuntu systems, such as the one I have here that requires this fix.

* x86-32: Pass the full resource data to ioremap()Linus Torvalds2008-03-24
| | | | | | | | | | | | | | | | It appears that 64-bit PCI resources cannot possibly ever have worked on x86-32 even when the RESOURCES_64BIT config option was set, because any driver that tried to [pci_]ioremap() the resource would have been unable to do so because the high 32 bits would have been silently dropped on the floor by the ioremap() routines that only used "unsigned long". Change them to use "resource_size_t" instead, which properly encodes the whole 64-bit resource data if RESOURCES_64BIT is enabled. Acked-by: H.

This patch tries to fix the aforementioned issues and implements strict_strtox serial functions, kernel/params.c uses them to strictly validate input, so module params will reject such values as 0x1234xxxx and returns an error: write error: Invalid argument Any modules which export numeric sysfs node can use strict_strtox instead of simple_strtox to reject any invalid input.

Counters are placed in SLUB's per cpu data structure. The per cpu structure may be extended by the statistics to grow larger than one cacheline which will increase the cache footprint of SLUB. There is a compile option to enable/disable the inclusion of the runtime statistics and its off by default. The slabinfo tool is enhanced to support these statistics via two options: -D Switches the line of information displayed for a slab from size mode to activity mode. -A Sorts the slabs displayed by activity. This allows the display of the slabs most important to the performance of a certain load. -r Report option will report detailed statistics on Example (tbench load): slabinfo -AD ->Shows the most active slabs Name Objects Alloc Free %Fast skbuff_fclone_cache 33 111953835 111953835 99 99 :0000192 2666 5283688 5281047 99 99 :0001024 849 5247230 5246389 83 83 vm_area_struct 1349 119642 118355 91 22 :0004096 15 66753 66751 98 98 :0000064 2067 25297 23383 98 78 dentry 10259 28635 18464 91 45 :0000080 11004 18950 8089 98 98 :0000096 1703 12358 10784 99 98 :0000128 762 10582 9875 94 18 :0000512 184 9807 9647 95 81 :0002048 479 9669 9195 83 65 anon_vma 777 9461 9002 99 71 kmalloc-8 6492 9981 5624 99 97 :0000768 258 7174 6931 58 15 So the skbuff_fclone_cache is of highest importance for the tbench load.

* radix-tree: avoid atomic allocations for preloaded insertionsNick Piggin2008-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most pagecache (and some other) radix tree insertions have the great opportunity to preallocate a few nodes with relaxed gfp flags. But the preallocation is squandered when it comes time to allocate a node, we default to first attempting a GFP_ATOMIC allocation -- that doesn't normally fail, but it can eat into atomic memory reserves that we don't need to be using. Another upshot of this is that it removes the sometimes highly contended zone->lock from underneath tree_lock. Pagecache insertions are always performed with a radix tree preload, and after this change, such a situation will never fall back to kmem_cache_alloc within radix_tree_node_alloc. David Miller reports seeing this allocation fail on a highly threaded sparc64 system: [527319.459981] dd: page allocation failure. order:0, mode:0x20 [527319.460403] Call Trace: [527319.460568] [00000000004b71e0] __slab_alloc+0x1b0/0x6a8 [527319.460636] [00000000004b7bbc] kmem_cache_alloc+0x4c/0xa8 [527319.460698] [000000000055309c] radix_tree_node_alloc+0x20/0x90 [527319.460763] [0000000000553238] radix_tree_insert+0x12c/0x260 [527319.460830] [0000000000495cd0] add_to_page_cache+0x38/0xb0 [527319.460893] [00000000004e4794] mpage_readpages+0x6c/0x134 [527319.460955] [000000000049c7fc] __do_page_cache_readahead+0x170/0x280 [527319.461028] [000000000049cc88] ondemand_readahead+0x208/0x214 [527319.461094] [0000000000496018] do_generic_mapping_read+0xe8/0x428 [527319.461152] [0000000000497948] generic_file_aio_read+0x108/0x170 [527319.461217] [00000000004badac] do_sync_read+0x88/0xd0 [527319.461292] [00000000004bb5cc] vfs_read+0x78/0x10c [527319.461361] [00000000004bb920] sys_read+0x34/0x60 [527319.461424] [0000000000406294] linux_sparc_syscall32+0x3c/0x40 The calltrace is significant: __do_page_cache_readahead allocates a number of pages with GFP_KERNEL, and hence it should have reclaimed sufficient memory to satisfy GFP_ATOMIC allocations. However after the list of pages goes to mpage_readpages, there can be significant intervals (including disk IO) before all the pages are inserted into the radix-tree. So the reserves can easily be depleted at that point. The patch is confirmed to fix the problem. Signed-off-by: Nick Piggin <npiggin@suse.de> Cc: "David S.

* x86: early boot debugging via FireWire (ohci1394_dma=early)Bernhard Kaindl2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new configuration option, which adds support for a new early_param which gets checked in arch/x86/kernel/setup_{32,64}.c:setup_arch() to decide wether OHCI-1394 FireWire controllers should be initialized and enabled for physical DMA access to allow remote debugging of early problems like issues ACPI or other subsystems which are executed very early. If the config option is not enabled, no code is changed, and if the boot paramenter is not given, no new code is executed, and independent of that, all new code is freed after boot, so the config option can be even enabled in standard, non-debug kernels. With specialized tools, it is then possible to get debugging information from machines which have no serial ports (notebooks) such as the printk buffer contents, or any data which can be referenced from global pointers, if it is stored below the 4GB limit and even memory dumps of of the physical RAM region below the 4GB limit can be taken without any cooperation from the CPU of the host, so the machine can be crashed early, it does not matter. In the extreme, even kernel debuggers can be accessed in this way. I wrote a small kgdb module and an accompanying gdb stub for FireWire which allows to gdb to talk to kgdb using remote remory reads and writes over FireWire. An version of the gdb stub fore FireWire is able to read all global data from a system which is running a a normal kernel without any kernel debugger, without any interruption or support of the system's CPU. That way, e.g. the task struct and so on can be read and even manipulated when the physical DMA access is granted. A HOWTO is included in this patch, in Documentation/debugging-via-ohci1394.txt and I've put a copy online at ftp://ftp.suse.de/private/bk/firewire/docs/debugging-via-ohci1394.txt It also has links to all the tools which are available to make use of it another copy of it is online at: ftp://ftp.suse.de/private/bk/firewire/kernel/ohci1394_dma_early-v2.diff Signed-Off-By: Bernhard Kaindl <bk@suse.de> Tested-By: Thomas Renninger <trenn@suse.de> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

| | | | | | | | | | | | | | | | | | | | | 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.
