To return -EINPROGRESS on success in padata_do_parallel was considered to be odd. This patch changes this to return zero on success. Also the only user of padata, pcrypt is adapted to convert a return of zero to -EINPROGRESS within the crypto layer. This also removes the pcrypt fallback if padata_do_parallel was called on a not running padata instance as we can't handle it anymore. This fallback was unused, so it's save to remove it.

This patch fixes a bug when the padata cpumask does not intersect with the active cpumask. In this case we get a division by zero in padata_alloc_pd and we end up with a useless padata instance. Padata can end up with an empty cpumask for two reasons: 1. A user removed the last cpu that belongs to the padata cpumask and the active cpumask. 2. The last cpu that belongs to the padata cpumask and the active cpumask goes offline. We introduce a function padata_validate_cpumask to check if the padata cpumask does intersect with the active cpumask. If the cpumasks do not intersect we mark the instance as invalid, so it can't be used. We do not allocate the cpumask dependend recources in this case. This fixes the division by zero and keeps the padate instance in a consistent state. It's not possible to trigger this bug by now because the only padata user, pcrypt uses always the possible cpumask.

This patch makes padata_stop to block until the padata instance is unused. Also we split padata_stop to a locked and a unlocked version. This is in preparation to be able to change the cpumask after a call to patata stop.

This patch introduces the PADATA_INVALID flag which is checked on padata start. This will be used to mark a padata instance as invalid, if the padata cpumask does not intersect with the active cpumask. we change padata_start to return an error if the PADATA_INVALID is set. Also we adapt the only padata user, pcrypt to this change. Signed-off-by: NSteffen Klassert <steffen.klassert@secunet.com> Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

This fixes the broken autoloading of the corresponding twofish assembler ciphers on x86 and x86_64 if they are available. The module name of the generic implementation was in conflict with the alias in the assembler modules. The generic twofish c implementation is renamed to twofish_generic according to the other algorithms with assembler implementations and an module alias is added for 'twofish'. You can now load 'twofish' giving you the best implementation by priority, 'twofish-generic' to get the c implementation or 'twofish-asm' to get the assembler version of cipher.

This reverts commit 480b02df, since Rafael reports that it causes occasional kernel paging request faults in load_module(). Dropping the module lock and re-taking it deep in the call-chain is definitely not the right thing to do. That just turns the mutex from a lock into a "random non-locking data structure" that doesn't actually protect what it's supposed to protect. Requested-and-tested-by: NRafael J.

This adds: alias: devname:<name> to some common kernel modules, which will allow the on-demand loading of the kernel module when the device node is accessed. Ideally all these modules would be compiled-in, but distros seems too much in love with their modularization that we need to cover the common cases with this new facility. It will allow us to remove a bunch of pretty useless init scripts and modprobes from init scripts. The static device node aliases will be carried in the module itself. The program depmod will extract this information to a file in the module directory: $ cat /lib/modules/2.6.34-00650-g537b60d1-dirty/modules.devname # Device nodes to trigger on-demand module loading. microcode cpu/microcode c10:184 fuse fuse c10:229 ppp_generic ppp c108:0 tun net/tun c10:200 dm_mod mapper/control c10:235 Udev will pick up the depmod created file on startup and create all the static device nodes which the kernel modules specify, so that these modules get automatically loaded when the device node is accessed: $ /sbin/udevd --debug ... static_dev_create_from_modules: mknod '/dev/cpu/microcode' c10:184 static_dev_create_from_modules: mknod '/dev/fuse' c10:229 static_dev_create_from_modules: mknod '/dev/ppp' c108:0 static_dev_create_from_modules: mknod '/dev/net/tun' c10:200 static_dev_create_from_modules: mknod '/dev/mapper/control' c10:235 udev_rules_apply_static_dev_perms: chmod '/dev/net/tun' 0666 udev_rules_apply_static_dev_perms: chmod '/dev/fuse' 0666 A few device nodes are switched to statically allocated numbers, to allow the static nodes to work. This might also useful for systems which still run a plain static /dev, which is completely unsafe to use with any dynamic minor numbers. Note: The devname aliases must be limited to the *common* and *single*instance* device nodes, like the misc devices, and never be used for conceptually limited systems like the loop devices, which should rather get fixed properly and get a control node for losetup to talk to, instead of creating a random number of device nodes in advance, regardless if they are ever used. This facility is to hide the mess distros are creating with too modualized kernels, and just to hide that these modules are not compiled-in, and not to paper-over broken concepts.
