2010-10-06SLUB: Fix memory hotplug with !NUMAPekka Enberg1-1/+1
This patch fixes the following build breakage when memory hotplug is enabled on UMA configurations: /home/test/linux-2.6/mm/slub.c: In function 'kmem_cache_init': /home/test/linux-2.6/mm/slub.c:3031:2: error: 'slab_memory_callback' undeclared (first use in this function) /home/test/linux-2.6/mm/slub.c:3031:2: note: each undeclared identifier is reported only once for each function it appears in make[2]: *** [mm/slub.o] Error 1 make[1]: *** [mm] Error 2 make: *** [sub-make] Error 2 Reported-by: Zimny Lech <napohybelskurwysynom2010@gmail.com> Acked-by: Christoph Lameter <cl@linux.com> Signed-off-by: Pekka Enberg <penberg@kernel.org>

2010-10-02percpu: use percpu allocator on UP tooTejun Heo6-65/+71
On UP, percpu allocations were redirected to kmalloc. This has the following problems. * For certain amount of allocations (determined by PERCPU_DYNAMIC_EARLY_SLOTS and PERCPU_DYNAMIC_EARLY_SIZE), percpu allocator can be used before the usual kernel memory allocator is brought online. On SMP, this is used to initialize the kernel memory allocator. * percpu allocator honors alignment upto PAGE_SIZE but kmalloc() doesn't. For example, workqueue makes use of larger alignments for cpu_workqueues. Currently, users of percpu allocators need to handle UP differently, which is somewhat fragile and ugly. Other than small amount of memory, there isn't much to lose by enabling percpu allocator on UP. It can simply use kernel memory based chunk allocation which was added for SMP archs w/o MMUs. This patch removes mm/percpu_up.c, builds mm/percpu.c on UP too and makes UP build use percpu-km. As percpu addresses and kernel addresses are always identity mapped and static percpu variables don't need any special treatment, nothing is arch dependent and mm/percpu.c implements generic setup_per_cpu_areas() for UP.

2010-10-02percpu: reduce PCPU_MIN_UNIT_SIZE to 32kTejun Heo1-1/+1
In preparation of enabling percpu allocator for UP, reduce PCPU_MIN_UNIT_SIZE to 32k. On UP, the first chunk doesn't have to include static percpu variables and chunk size can be smaller which is important as UP percpu allocator will use contiguous kernel memory to populate chunks. PCPU_MIN_UNIT_SIZE also determines the maximum supported allocation size but 32k should still be enough. Signed-off-by: Tejun Heo <tj@kernel.org>

2010-10-02SLUB: Fix merged slab cache namesPekka Enberg1-1/+20
As explained by Linus "I'm Proud to be an American" Torvalds: Looking at the merging code, I actually think it's totally buggy. If you have something like this: - load module A: create slab cache A - load module B: create slab cache B that can merge with A - unload module A - "cat /proc/slabinfo": BOOM. Oops. exactly because the name is not handled correctly, and you'll have module B holding open a slab cache that has a name pointer that points to module A that no longer exists. This patch fixes the problem by using kstrdup() to allocate dynamic memory for ->name of "struct kmem_cache" as suggested by Christoph Lameter.

Move the gfpflags masking into the hooks for checkers and into the slowpaths. gfpflag masking requires access to a global variable and thus adds an additional cacheline reference to the hotpaths.

2010-10-02slub: Dynamically size kmalloc cache allocationsChristoph Lameter2-58/+140
kmalloc caches are statically defined and may take up a lot of space just because the sizes of the node array has to be dimensioned for the largest node count supported. This patch makes the size of the kmem_cache structure dynamic throughout by creating a kmem_cache slab cache for the kmem_cache objects. The bootstrap occurs by allocating the initial one or two kmem_cache objects from the page allocator.

libata depends on scsi_host_template for module reference counting and sht's should be owned by each low level driver. During libahci split, the sht was left with libahci.ko leaving the actual low level drivers not reference counted. This made ahci and ahci_platform always unloadable even while they're being actively used.

Commit e40cc4bdfd4b89813f072f72bd9c7055814d3f0f introduced a build breakage if CONFIG_SMP is undefined. This commit fixes the problem. This fix is only a workaround. For a real fix, cpu_sibling_mask() should be defined in UP include code, eg in linux/smp.h, and asm/smp.h should not be included directly. This fix is currently not possible because asm/smp.h defines cpu_sibling_mask() unconditionally and is included directly from many source files.

Fixes kernel bugzilla #16603 tcp_sendmsg() truncates iov_len to an 'int' which a 4GB write to write zero bytes, for example. There is also the problem higher up of how verify_iovec() works. It wants to prevent the total length from looking like an error return value. However it does this using 'int', but syscalls return 'long' (and thus signed 64-bit on 64-bit machines). So it could trigger false-positives on 64-bit as written. So fix it to use 'long'.

The PKT_CTRL_CMD_STATUS device ioctl retrieves a pointer to a pktcdvd_device from the global pkt_devs array. The index into this array is provided directly by the user and is a signed integer, so the comparison to ensure that it falls within the bounds of this array will fail when provided with a negative index. This can be used to read arbitrary kernel memory or cause a crash due to an invalid pointer dereference. This can be exploited by users with permission to open /dev/pktcdvd/control (on many distributions, this is readable by group "cdrom").
