* block: fix blk_register_queue() return valueAkinobu Mita2008-04-211-2/+8
| | | | | | | | | | | | | | | | | | blk_register_queue() returns -ENXIO when queue->request_fn is NULL. But there are some block drivers that call blk_register_queue() via add_disk() with queue->request_fn == NULL. (For example, brd, loop) Although no one checks return value of blk_register_queue(), this patch makes it return 0 instead of -ENXIO when queue->request_fn is NULL, Also this patch adds warning when blk_register_queue() and blk_unregister_queue() are called with queue == NULL rather than ignore invalid usage silently.

* block: fix memory hotplug and bouncing in block layerAndi Kleen2008-04-211-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only noticed this while hacking something else, no test case. blk_max_low_pfn is initialized once at bootup by the block layer from max_low_pfn. But max_low_pfn is not necessarily constant over the runtime of the system when you consider memory hotplug. What could happen if that someone adds memory later the block layer wouldn't get updated and then start bouncing memory unnecessarily. Also on 64bit blk_max_low_pfn actually isn't needed because it just disables bouncing essentially and there is no highmem. And nobody can pass pfns > max_low_pfn to the block layer, because those wouldn't have a struct page and I suspect block layer wouldn't be very happy without that. So set BLK_BOUNCE_HIGH to infinity (-1ULL) on 64bit. That avoids the problem of having to update it on memory hotadd. On 32bit I kept the same behaviour because at least on i386 memory hotadd only adds HIGHMEM, never lowmem. BLK_BOUNCE_ANY is always set to infinity on both 32 and 64bit.

* Kconfig: clean up block/Kconfig help descriptionsNick Andrew2008-04-211-23/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modify the help descriptions of block/Kconfig for clarity, accuracy and consistency. Refactor the BLOCK description a bit. The wording "This permits ... to be removed" isn't quite right; the block layer is removed when the option is disabled, whereas most descriptions talk about what happens when the option is enabled. Reformat the list of what is affected by disabling the block layer. Add more examples of large block devices to LBD and strive for technical accuracy; block devices of size _exactly_ 2TB require CONFIG_LBD, not only "bigger than 2TB". Also try to say (perhaps not very clearly) that the config option is only needed when you want to have individual block devices of size >= 2TB, for example if you had 3 x 1TB disks in your computer you'd have a total storage size of 3TB but you wouldn't need the option unless you want to aggregate those disks into a RAID or LVM. Improve terminology and grammar on BLK_DEV_IO_TRACE. I also added the boilerplate "If unsure, say N" to most options. Precisely say "2TB and larger" for LSF. Indent the help text for BLK_DEV_BSG by 2 spaces in accordance with the standard.

* block: move the padding adjustment to blk_rq_map_sgFUJITA Tomonori2008-04-214-20/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | blk_rq_map_user adjusts bi_size of the last bio. It breaks the rule that req->data_len (the true data length) is equal to sum(bio). It broke the scsi command completion code. commit e97a294ef6938512b655b1abf17656cf2b26f709 was introduced to fix the above issue. However, the partial completion code doesn't work with it. The commit is also a layer violation (scsi mid-layer should not know about the block layer's padding). This patch moves the padding adjustment to blk_rq_map_sg (suggested by James). The padding works like the drain buffer. This patch breaks the rule that req->data_len is equal to sum(sg), however, the drain buffer already broke it. So this patch just restores the rule that req->data_len is equal to sub(bio) without breaking anything new. Now when a low level driver needs padding, blk_rq_map_user and blk_rq_map_user_iov guarantee there's enough room for padding. blk_rq_map_sg can safely extend the last entry of a scatter list. blk_rq_map_sg must extend the last entry of a scatter list only for a request that got through bio_copy_user_iov. This patches introduces new REQ_COPY_USER flag.

* block: add bio_copy_user_iov support to blk_rq_map_user_iovFUJITA Tomonori2008-04-211-5/+17
| | | | | | | | | | | | | | | | | | | | | | | | With this patch, blk_rq_map_user_iov uses bio_copy_user_iov when a low level driver needs padding or a buffer in sg_iovec isn't aligned. That is, it uses temporary kernel buffers instead of mapping user pages directly. When a LLD needs padding, later blk_rq_map_sg needs to extend the last entry of a scatter list. bio_copy_user_iov guarantees that there is enough space for padding by using temporary kernel buffers instead of user pages. blk_rq_map_user_iov needs buffers in sg_iovec to be aligned. The comment in blk_rq_map_user_iov indicates that drivers/scsi/sg.c also needs buffers in sg_iovec to be aligned. Actually, drivers/scsi/sg.c works with unaligned buffers in sg_iovec (it always uses temporary kernel buffers).

* block: convert bio_copy_user to bio_copy_user_iovFUJITA Tomonori2008-04-212-41/+119
| | | | | | | | | | | | | | | | | | | This patch enables bio_copy_user to take struct sg_iovec (renamed bio_copy_user_iov). bio_copy_user uses bio_copy_user_iov internally as bio_map_user uses bio_map_user_iov. The major changes are: - adds sg_iovec array to struct bio_map_data - adds __bio_copy_iov that copy data between bio and sg_iovec. bio_copy_user_iov and bio_uncopy_user use it.

* loop: manage partitions in disk imageLaurent Vivier2008-04-211-5/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows to use loop device with partitionned disk image. Original behavior of loop is not modified. A new parameter is introduced to define how many partition we want to be able to manage per loop device. This parameter is "max_part". For instance, to manage 63 partitions / loop device, we will do: # modprobe loop max_part=63 # ls -l /dev/loop?* brw-rw---- 1 root disk 7, 0 2008-03-05 14:55 /dev/loop0 brw-rw---- 1 root disk 7, 64 2008-03-05 14:55 /dev/loop1 brw-rw---- 1 root disk 7, 128 2008-03-05 14:55 /dev/loop2 brw-rw---- 1 root disk 7, 192 2008-03-05 14:55 /dev/loop3 brw-rw---- 1 root disk 7, 256 2008-03-05 14:55 /dev/loop4 brw-rw---- 1 root disk 7, 320 2008-03-05 14:55 /dev/loop5 brw-rw---- 1 root disk 7, 384 2008-03-05 14:55 /dev/loop6 brw-rw---- 1 root disk 7, 448 2008-03-05 14:55 /dev/loop7 And to attach a raw partitionned disk image, the original losetup is used: # losetup -f etch.img # ls -l /dev/loop?* brw-rw---- 1 root disk 7, 0 2008-03-05 14:55 /dev/loop0 brw-rw---- 1 root disk 7, 1 2008-03-05 14:57 /dev/loop0p1 brw-rw---- 1 root disk 7, 2 2008-03-05 14:57 /dev/loop0p2 brw-rw---- 1 root disk 7, 5 2008-03-05 14:57 /dev/loop0p5 brw-rw---- 1 root disk 7, 64 2008-03-05 14:55 /dev/loop1 brw-rw---- 1 root disk 7, 128 2008-03-05 14:55 /dev/loop2 brw-rw---- 1 root disk 7, 192 2008-03-05 14:55 /dev/loop3 brw-rw---- 1 root disk 7, 256 2008-03-05 14:55 /dev/loop4 brw-rw---- 1 root disk 7, 320 2008-03-05 14:55 /dev/loop5 brw-rw---- 1 root disk 7, 384 2008-03-05 14:55 /dev/loop6 brw-rw---- 1 root disk 7, 448 2008-03-05 14:55 /dev/loop7 # mount /dev/loop0p1 /mnt # ls /mnt bench cdrom home lib mnt root srv usr bin dev initrd lost+found opt sbin sys var boot etc initrd.img media proc selinux tmp vmlinuz # umount /mnt # losetup -d /dev/loop0 Of course, the same behavior can be done using kpartx on a loop device, but modifying loop avoids to stack several layers of block device (loop + device mapper), this is a very light modification (40% of modifications are to manage the new parameter).

* cdrom: use kmalloced buffers instead of buffers on stackThomas Bogendoerfer2008-04-211-93/+181
| | | | | | | | | | If cdrom commands are issued to a scsi drive in most cases the buffer will be filled via dma.

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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | found dev_get_by_index() may return NULL if nothing is found. In net/netlabel/netlabel_unlabeled.c::netlbl_unlabel_staticlist_gen() the function is called, but the return value is never checked. If it returns NULL then we'll deref a NULL pointer on the very next line. I checked the callers, and I don't think this can actually happen today, but code changes over time and in the future it might happen and it does no harm to be defensive and check for the failure, so that if/when it happens we'll fail gracefully instead of crashing.

| * | [INET]: Drop the inet_inherit_port() call.Pavel Emelyanov2008-04-173-9/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As I can see from the code, two places (tcp_v6_syn_recv_sock and dccp_v6_request_recv_sock) that call this one already run with BHs disabled, so it's safe to call __inet_inherit_port there. Besides (in case I missed smth with code review) the calltrace tcp_v6_syn_recv_sock `- tcp_v4_syn_recv_sock `- __inet_inherit_port and the similar for DCCP are valid, but assumes BHs to be disabled.

| | * | natsemi: fix MMIO for PPC 44x platformsSergei Shtylyov2008-04-171-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver stores the PCI resource address into 'unsigned long' variable before calling ioremap() on it. This warrants a kernel oops when the registers are accessed on PPC 44x platforms which (being 32-bit) have PCI memory space mapped beyond 4 GB. The arch/ppc/ kernel has a fixup in ioremap() that creates an illusion of the PCI memory resources are mapped below 4 GB, but arch/powerpc/ code got rid of this trick, having instead CONFIG_RESOURCES_64BIT enabled.
