2008-04-19sysdev: detect multiple driver registrationsBen Dooks
I've just found how easy it is to accidentally register a sysdev_driver for two different classes. When this happens, bad things happen as the sysdev_driver structure keeps has the list entry for the driver registration. The following patch makes a WARN_ON() if this happens, although I think BUG_ON or returning -EAGAIN could also be valid responses to this.

2008-04-19driver core: cpu: fix section mismatch in cpu.c:store_onlineSam Ravnborg
Fix following warning: WARNING: vmlinux.o(.text+0x64609c): Section mismatch in reference from the function store_online() to the function .cpuinit.text:cpu_up() store_online() is defined inside a HOTPLUG_CPU block so references are OK. Ignore references by annotating store_online() with __ref. Note: This is needed because cpu_up() most likely should not have been __cpuinit but all the hotplug cpu code misuses the __cpuinit annotation.

2008-04-19PNP: add all PNP card device id's as individual aliasesKay Sievers
The current PNP combined card + devices module aliase can never ever match anything, because these values are not available all at the same time to request a module. Instead of adding the combined alias, we add the device id's all as individual aliases. Device id's are exported by the PNP bus and can now properly used to request the loading of a matching module. The module snd-sbawe currently exports aliases, which can never match anything: alias: pnp:cCTLXXXXdCTL0045dCTL0022* alias: pnp:cCTLXXXXdCTL0044dCTL0023* alias: pnp:cCTLXXXXdCTL0042dCTL0022* alias: pnp:cCTLXXXXdCTL0041dCTL0021* alias: pnp:cCTLXXXXdCTL0031dCTL0021* alias: pnp:cCTL00eddCTL0041dCTL0070* alias: pnp:cCTL00e9dCTL0045dCTL0022* alias: pnp:cCTL00e4dCTL0045dCTL0022* alias: pnp:cCTL00c7dCTL0045dCTL0022* alias: pnp:cCTL00c5dCTL0045dCTL0022* alias: pnp:cCTL00c3dCTL0045dCTL0022* alias: pnp:cCTL00c1dCTL0042dCTL0022* alias: pnp:cCTL00b2dCTL0044dCTL0023* alias: pnp:cCTL009edCTL0044dCTL0023* alias: pnp:cCTL009ddCTL0042dCTL0022* alias: pnp:cCTL009fdCTL0041dCTL0021* alias: pnp:cCTL009cdCTL0041dCTL0021* alias: pnp:cCTL009adCTL0041dCTL0021* alias: pnp:cCTL0054dCTL0031dCTL0021* alias: pnp:cCTL0048dCTL0031dCTL0021* alias: pnp:cCTL0047dCTL0031dCTL0021* alias: pnp:cCTL0046dCTL0031dCTL0021* alias: pnp:cCTL0045dCTL0031dCTL0021* alias: pnp:cCTL0044dCTL0031dCTL0021* alias: pnp:cCTL0043dCTL0031dCTL0021* alias: pnp:cCTL0042dCTL0031dCTL0021* alias: pnp:cCTL0039dCTL0031dCTL0021* alias: pnp:cCTL0035dCTL0031dCTL0021* With this patch it exports only the device id's, as properly matchable aliases: alias: pnp:dCTL0070* alias: pnp:dCTL0045* alias: pnp:dCTL0023* alias: pnp:dCTL0044* alias: pnp:dCTL0022* alias: pnp:dCTL0042* alias: pnp:dCTL0041* alias: pnp:dCTL0021* alias: pnp:dCTL0031* Now, the exported value of the PNP bus can be used to autoload a matching module: $ modprobe --first-time -n -v pnp:dCTL0045 insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/core/snd-rawmidi.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/drivers/mpu401/snd-mpu401-uart.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/core/snd-hwdep.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/isa/sb/snd-sb-common.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/isa/sb/snd-sb16-csp.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/isa/sb/snd-sb16-dsp.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/drivers/opl3/snd-opl3-lib.ko insmod /lib/modules/2.6.24-rc6-g5b825ed2-dirty/kernel/sound/isa/sb/snd-sbawe.ko $ grep CTL0045 /sys/bus/pnp/devices/*/id /sys/bus/pnp/devices/01:01.00/id:CTL0045 Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2008-04-19driver core: Convert debug functions declared inline __attribute__((format ↵Joe Perches
(printf,x,y) to statement expression macros When DEBUG is not defined, pr_debug and dev_dbg and some other local debugging functions are specified as: "inline __attribute__((format (printf, x, y)))" This is done to validate printk arguments when not debugging. Converting these functions to macros or statement expressions "do { if (0) printk(fmt, ##arg); } while (0)" or "({ if (0) printk(fmt, ##arg); 0; }) makes at least gcc 4.2.2 produce smaller objects. This has the additional benefit of allowing the optimizer to avoid calling functions like print_mac that might have been arguments to the printk. defconfig x86 current: $ size vmlinux text data bss dec hex filename 4716770 474560 618496 5809826 58a6a2 vmlinux all converted: (More patches follow) $ size vmlinux text data bss dec hex filename 4716642 474560 618496 5809698 58a622 vmlinux Even kernel/sched.o, which doesn't even use these functions, becomes smaller.

2008-04-19driver core: register_memory/unregister_memory clean ups and bugfixBadari Pulavarty
register_memory()/unregister_memory() never gets called with "root". unregister_memory() is accessing kobject_name of the object just freed up. Since no one uses the code, lets take the code out. And also, make register_memory() static. Another bug fix - before calling unregister_memory() remove_memory_block() gets a ref on kobject. unregister_memory() need to drop that ref before calling sysdev_unregister().

2008-04-19UIO: Implement a UIO interface for the SMX CryptengineBen Nizette
This patch implements a UIO interface for the SMX Cryptengine. The Cryptengine found on the Nias Digital SMX board is best suited for a UIO interface. It is not wired in to the cryptographic API as the engine handles it's own keys, algorithms, everything. All that we know about is that if there's room in the buffer, you can write data to it and when there's data ready, you read it out again. There isn't necessarily even any direct correlation between data going in and data coming out again, the engine may consume or generate data all on its own. This driver is for proprietary hardware but we're always told to submit the drivers anyway; here you are. :-) This is version 4 of this patch and addresses all issues raised by Hans-Jürgen Koch and Paul Mundt in their reviews. Slightly altered is Paul's suggestion to use DRV_NAME and DRV_VERSION as the UIO version and name. While at the moment they are the same, there is no reason for them to stay that way. Nevertheless we now at least provide a MODULE_VERSION macro to keep modinfo happy.

2008-04-19Security: Introduce security= boot parameterAhmed S. Darwish
Add the security= boot parameter. This is done to avoid LSM registration clashes in case of more than one bult-in module. User can choose a security module to enable at boot. If no security= boot parameter is specified, only the first LSM asking for registration will be loaded. An invalid security module name will be treated as if no module has been chosen. LSM modules must check now if they are allowed to register by calling security_module_enable(ops) first. Modify SELinux and SMACK to do so. Do not let SMACK register smackfs if it was not chosen on boot. Smackfs assumes that smack hooks are registered and the initial task security setup (swapper->security) is done.

2008-04-18[NET]: Fix and allocate less memory for ->priv'less netdevicesAlexey Dobriyan
This patch effectively reverts commit d0498d9ae1a5cebac363e38907266d5cd2eedf89 aka "[NET]: Do not allocate unneeded memory for dev->priv alignment." It was found to be buggy because of final unconditional += NETDEV_ALIGN_CONST removal. For example, for sizeof(struct net_device) being 2048 bytes, "alloc_size" was also 2048 bytes, but allocator with debugging options turned on started giving out !32-byte aligned memory resulting in redzones overwrites. Patch does small optimization in ->priv'less case: bumping size to next 32-byte boundary was always done to ensure ->priv will also be aligned. But, no ->priv, no need to do that.

The kernel now panics reliably on boot if you have a SATAPI device connected. The problem was introduced by the libata merge trying to pull out all the SFF code into a separate module. Unfortunately, if you're a satapi device you usually need to call atapi_request_sense, which has a bare invocation of a SFF callback which is NULL on non-SFF HBAs.

2008-04-18[SCSI] bsg: takes a ref to struct device in fops->openFUJITA Tomonori
bsg_register_queue() takes a ref to struct device that a caller passes. For example, bsg takes a ref to the sdev_gendev for scsi devices. However, bsg doesn't inrease the refcount in fops->open. So while an application opens a bsg device, the scsi device that the bsg device holds can go away (bsg also takes a ref to a queue, but it doesn't prevent the device from going away). With this patch, bsg increases the refcount of struct device in fops->open and decreases it in fops->release.
