* crypto: authenc - Avoid using clobbered request pointerHerbert Xu2008-08-231-4/+6
| | | | | | | | | | | | | | | | | | Authenc works in two stages for encryption, it first encrypts and then computes an ICV. The context memory of the request is used by both operations. The problem is that when an asynchronous encryption completes, we will compute the ICV and then reread the context memory of the encryption to get the original request. It just happens that we have a buffer of 16 bytes in front of the request pointer, so ICVs of 16 bytes (such as SHA1) do not trigger the bug. However, any attempt to uses a larger ICV instantly kills the machine when the first asynchronous encryption is completed. This patch fixes this by saving the request pointer before we start the ICV computation. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* Reduce brokenness of CRIS headers_installDavid Woodhouse2008-08-201-1/+0
| | | | | | | | | | | | | | | | | I won't say 'fix', because they still look broken, although this will at least allow 'make ARCH=CRIS headers_install' to _complete_. For headers which are exported, we should probably choose between asm/arch-v10 and asm/arch-v32 by something that GCC defines -- we can't rely on a generated symlink. And we certainly can't export an arch/ directory which doesn't even exist. And the only thing that we seem to include from the arch/ directory is <asm/arch/ptrace.h> from <asm/ptrace.h> ... and that isn't exported in either arch-v10 or arch-v32 _anyway_.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent of_platform changes made of_bus_type_init() overwrite the bus type's .dev_attrs list, meaning that the "name" attribute that ibmebus devices previously had is no longer present. This is a user-visible regression which breaks the userspace eHCA support, since the eHCA userspace driver relies on the name attribute to check for valid adapters. This fixes it by providing the "name" attribute in the generic OF device code instead. Tested on POWER.

Currently, there is a possible reference-after-free in the spusched code - contexts may be freed after we have released their state_mutex in spusched_tick and find_victim.

While this is correct for isolated contexts, there's no need to enforce the npc restriction on non-isolated NOSCHED contexts. This means that NOSCHED contexts can only ever run with an entry point of 0x0. This change to spu_run_init allows setting of the npc (and, while we're at it, the privcntl) for non-isolated NOSCHED contexts. This allows us to run NOSCHED contexts from any entry point.

However, the hosts's state does not get set back to IBMVFC_INITIALIZING and scsi_block_requests does not get called again, which can result in queuecommand ops getting sent during discovery. This should not occur and may cause problems. One example is that we may no longer be logged into the target we send the command to, resulting in a failure which should not have occurred.

This is due to the current implementation's back-end vport handling being performed by the physical-HA's DPC thread where premature shutdown could lead to latent vport requests without a processor. This should also address a problem reported by Gal Rosen (http://marc.info/?l=linux-scsi&m=121731664417358&w=2) where the driver would attempt to awaken a previously torn-down DPC thread from interrupt context by implicitly calling wake_up_process() rather than the driver's qla2xxx_wake_dpc() helper. Rather, than reshuffle the remove_one() device-removal code, during unload, depend on the driver's timer to wake-up the DPC process, by limiting wake-ups based on an 'unloading' flag.

It turns out that prior to the SCST software reloading and returning it's "target-capable" abilities in the PRLI payload, the HBA would be re-initialized as an initiator-only type port. Since initiators typically classify themselves as an FCP-2 capable device, both software and firmware do not perform an explicit logout during port-loss. Unfortunately, as can be seen by the failure case, when the port (now target-capable) returns, firmware performs an ADISC without a follow-on PRLI, leaving stale 'initiator-only' data in the firmware's port database. Correct the discrepancy by performing the explicit logout during the transport's request to terminate-rport-io, thus synchronizing port states and ensuring a follow-on PRLI is performed.
