2007-05-02[CRYPTO] api: Add ablkcipher_request_set_tfmHerbert Xu
This patch adds ablkcipher_request_set_tfm for those users that need to manage the memory for ablkcipher requests directly. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2007-05-02[CRYPTO] cryptd: Add software async crypto daemonHerbert Xu
This patch adds the cryptd module which is a template that takes a synchronous software crypto algorithm and converts it to an asynchronous one by executing it in a kernel thread. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2007-05-02[CRYPTO] api: Do not remove users unless new algorithm matchesHerbert Xu
As it is whenever a new algorithm with the same name is registered users of the old algorithm will be removed so that they can take advantage of the new algorithm. This presents a problem when the new algorithm is not equivalent to the old algorithm. In particular, the new algorithm might only function on top of the existing one. Hence we should not remove users unless they can make use of the new algorithm. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2007-05-02[CRYPTO] api: Add async blkcipher typeHerbert Xu
This patch adds the mid-level interface for asynchronous block ciphers. It also includes a generic queueing mechanism that can be used by other asynchronous crypto operations in future. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2007-05-02[CRYPTO] templates: Pass type/mask when creating instancesHerbert Xu
This patch passes the type/mask along when constructing instances of templates. This is in preparation for templates that may support multiple types of instances depending on what is requested. For example, the planned software async crypto driver will use this construct. For the moment this allows us to check whether the instance constructed is of the correct type and avoid returning success if the type does not match.

2007-05-02[CRYPTO] api: Add async block cipher interfaceHerbert Xu
This patch adds the frontend interface for asynchronous block ciphers. In addition to the usual block cipher parameters, there is a callback function pointer and a data pointer. The callback will be invoked only if the encrypt/decrypt handlers return -EINPROGRESS. In other words, if the return value of zero the completion handler (or the equivalent code) needs to be invoked by the caller. The request structure is allocated and freed by the caller. Its size is determined by calling crypto_ablkcipher_reqsize(). The helpers ablkcipher_request_alloc/ablkcipher_request_free can be used to manage the memory for a request.

2007-04-30power management: force pm_ops.valid callback to be assignedJohannes Berg
This patch changes the docs and behaviour from "all states valid" to "no states valid" if no .valid callback is assigned. Users of pm_ops that only need mem sleep can assign pm_valid_only_mem without any overhead, others will require more elaborate callbacks. Now that all users of pm_ops have a .valid callback this is a safe thing to do and prevents things from getting messy again as they were before.

2007-04-30power management: implement pm_ops.valid for everybodyJohannes Berg
Almost all users of pm_ops only support mem sleep, don't check in .valid and don't reject any others in .prepare so users can be confused if they check /sys/power/state, especially when new states are added (these would then result in s-t-r although they're supposed to be something different). This patch implements a generic pm_valid_only_mem function that is then exported for users and puts it to use in almost all existing pm_ops.

2007-04-30rework pm_ops pm_disk_mode, kill misuseJohannes Berg
This patch series cleans up some misconceptions about pm_ops. Some users of the pm_ops structure attempt to use it to stop the user from entering suspend to disk, this, however, is not possible since the user can always use "shutdown" in /sys/power/disk and then the pm_ops are never invoked. Also, platforms that don't support suspend to disk simply should not allow configuring SOFTWARE_SUSPEND (read the help text on it, it only selects suspend to disk and nothing else, all the other stuff depends on PM). The pm_ops structure is actually intended to provide a way to enter platform-defined sleep states (currently supported states are "standby" and "mem" (suspend to ram)) and additionally (if SOFTWARE_SUSPEND is configured) allows a platform to support a platform specific way to enter low-power mode once everything has been saved to disk. This is currently only used by ACPI (S4). This patch: The pm_ops.pm_disk_mode is used in totally bogus ways since nobody really seems to understand what it actually does. This patch clarifies the pm_disk_mode description. It also removes all the arm and sh users that think they can veto suspend to disk via pm_ops; not so since the user can always do echo shutdown > /sys/power/disk, they need to find a better way involving Kconfig or such. ACPI is the only user left with a non-zero pm_disk_mode. The patch also sets the default mode to shutdown again, but when a new pm_ops is registered its pm_disk_mode is selected as default, that way the default stays for ACPI where it is apparently required.

Today's print_symbol function dumps a kernel symbol with printk. This patch extends the functionality of kallsyms.c so that the symbol lookup function may be used without the printk.

2007-04-30[XFRM]: Restrict upper layer information by bundle.Masahide NAKAMURA
On MIPv6 usage, XFRM sub policy is enabled. When main (IPsec) and sub (MIPv6) policy selectors have the same address set but different upper layer information (i.e. protocol number and its ports or type/code), multiple bundle should be created. However, currently we have issue to use the same bundle created for the first time with all flows covered by the case. It is useful for the bundle to have the upper layer information to be restructured correctly if it does not match with the flow. 1. Bundle was created by two policies Selector from another policy is added to xfrm_dst. If the flow does not match the selector, it goes to slow path to restructure new bundle by single policy. 2. Bundle was created by one policy Flow cache is added to xfrm_dst as originated one. If the flow does not match the cache, it goes to slow path to try searching another policy.

2007-04-30[TCP]: Catch skb with S+L bugs earlierIlpo Järvinen
SACKED_ACKED and LOST are mutually exclusive with SACK, thus having their sum larger than packets_out is bug with SACK. Eventually these bugs trigger traps in the tcp_clean_rtx_queue with SACK but it's much more informative to do this here. Non-SACK TCP, however, could get more than packets_out duplicate ACKs which each increment sacked_out, so it makes sense to do this kind of limitting for non-SACK TCP but not for SACK enabled one. Perhaps the author had the opposite in mind but did the logic accidently wrong way around? Anyway, the sacked_out incrementer code for non-SACK already deals this issue before calling sync_left_out so this trapping can be done unconditionally.

2007-04-30[BLOCK] Don't pin lots of memory in mempoolsJens Axboe
Currently we scale the mempool sizes depending on memory installed in the machine, except for the bio pool itself which sits at a fixed 256 entry pre-allocation. There's really no point in "optimizing" this OOM path, we just need enough preallocated to make progress. A single unit is enough, lets scale it down to 2 just to be on the safe side.

2007-04-28[AF_IUCV/IUCV]: smp_call_function deadlockMartin Schwidefsky
Calling smp_call_function can lead to a deadlock if it is called from tasklet context. Fixing this deadlock requires to move the smp_call_function from the tasklet context to a work queue. To do that queue the path pending interrupts to a separate list and move the path cleanup out of iucv_path_sever to iucv_path_connect and iucv_path_pending. This creates a new requirement for iucv_path_connect: it may not be called from tasklet context anymore.

2007-04-28libata: Handle drives that require a spin-up command before first accessMark Lord
(S)ATA drives can be configured for "power-up in standby", a mode whereby a specific "spin up now!" command is required before the first media access. Currently, a drive with this feature enabled can not be used at all with libata, and once in this mode, the drive becomes a doorstop. The older drivers/ide subsystem at least enumerates the drive, so that it can be woken up after the fact from a userspace HDIO_* command, but not libata. This patch adds support to libata for the "power-up in standby" mode where a "spin up now!" command (SET_FEATURES) is needed. With this, libata will recognize such drives, spin them up, and then re-IDENTIFY them if necessary to get a full/complete set of drive features data. Drives in this state are determined by looking for special values in id[2], as documented in the current ATA specs.

Tested with various platforms/disks and confirmed to work with the Macintosh (which broke earlier) and ata_piix (breakage due to the LBA48 readback that Tejun fixed). For normal users this brings us, I believe, to feature parity with old IDE (and of course more featured in some areas too). Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-04-28libata: kill probe_ent and related helpersTejun Heo
All drivers are converted to new init model. Kill probe_ent, ata_device_add() and ata_pci_init_native_mode(). Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-04-28libata: add init helpers including ata_pci_prepare_native_host()Tejun Heo
These will be used to convert LLDs to new init model. * Add irq_handler field to port_info. In new init model, requesting IRQ is LLD's responsibility and libata doesn't need to know about irq_handler. Most LLDs can simply register their irq_handler but some need different irq_handler depending on specific chip. The added port_info->irq_handler field can be used by LLDs to select the matching IRQ handler in such cases. * Add ata_dummy_port_info. * Implement ata_pci_prepare_native_host(), a helper to alloc ATA host, acquire all resources and init the host in one go.

2007-04-28libata: convert native PCI host handling to new init modelTejun Heo
Convert native PCI host handling to alloc-init-register model. New function ata_pci_init_native_host() follows the new init model and replaces ata_pci_init_native_mode(). As there are remaining LLD users, the old function isn't removed yet. ata_pci_init_one() is reimplemented using the new function and now fully converted to new init model.

2007-04-28libata: implement ata_host_alloc_pinfo() and ata_host_register()Tejun Heo
Implement ata_host_alloc_pinfo() and ata_host_register(). These helpers will be used in the following patches to adopt new init model. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-04-28libata: separate out ata_host_alloc() and ata_host_register()Tejun Heo
Reorganize ata_host_alloc() and its subroutines into the following three functions. * ata_host_alloc() : allocates host and its ports. shost is not registered automatically. * ata_scsi_add_hosts() : allocates and adds shosts associated with an ATA host. Used by ata_host_register(). * ata_host_register() : takes a fully initialized ata_host structure and registers it to libata layer and probes it. Only ata_host_alloc() and ata_host_register() are exported. ata_device_add() is rewritten using the above functions. This patch does not introduce any observable behavior change. Things worth mentioning. * print_id is assigned at registration time and LLDs are allowed to overallocate ports and reduce host->n_ports during initialization. ata_host_register() will throw away unused ports automatically. * All SCSI host initialization stuff now resides in ata_scsi_add_hosts() in libata-scsi.c, where it should be. * ipr is now the only user of ata_host_init(). Either kill it by converting ipr to use ata_host_alloc() and friends or rename and move it to libata-scsi.c Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-04-28libata: separate out ata_host_start()Tejun Heo
Separate out ata_host_start() from ata_device_add(). ata_host_start() calls ->port_start on each port if available and freezes the port. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-04-28libata: allocate ap separately from shostTejun Heo
Don't embed ap inside shost. Allocate it separately and point it back from shosts's hostdata. This makes port allocation more flexible and allows regular ATA and SAS share host alloc/init paths. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
