* [PATCH] modules: add version and srcversion to sysfsMatt Domsch2005-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds version and srcversion files to /sys/module/${modulename} containing the version and srcversion fields of the module's modinfo section (if present). /sys/module/e1000 |-- srcversion `-- version This patch differs slightly from the version posted in January, as it now uses the new kstrdup() call in -mm. Why put this in sysfs? a) Tools like DKMS, which deal with changing out individual kernel modules without replacing the whole kernel, can behave smarter if they can tell the version of a given module. The autoinstaller feature, for example, which determines if your system has a "good" version of a driver (i.e. if the one provided by DKMS has a newer verson than that provided by the kernel package installed), and to automatically compile and install a newer version if DKMS has it but your kernel doesn't yet have that version. b) Because sysadmins manually, or with tools like DKMS, can switch out modules on the file system, you can't count on 'modinfo foo.ko', which looks at /lib/modules/${kernelver}/... actually matching what is loaded into the kernel already. Hence asking sysfs for this. c) as the unbind-driver-from-device work takes shape, it will be possible to rebind a driver that's built-in (no .ko to modinfo for the version) to a newly loaded module. sysfs will have the currently-built-in version info, for comparison. d) tech support scripts can then easily grab the version info for what's running presently - a question I get often. There has been renewed interest in this patch on linux-scsi by driver authors. As the idea originated from GregKH, I leave his Signed-off-by: intact, though the implementation is nearly completely new. Compiled and run on x86 and x86_64.

* [PATCH] knfsd: nfsd4: initialize recovery directoryNeilBrown2005-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NFSv4 clients are required to know what state they have on the server so that they can reclaim it on server reboot. However, it is possible for pathalogical combinations of server reboots and network partitions to leave a client in a state where it cannot know whether it has lost its state on the server. For this reason, rfc3530 requires that we store some information about clients to stable storage. So we maintain a directory /var/lib/nfs/v4recovery with a subdirectory for each client with active state. We leave open the possibility of including files underneath each such subdirectory with information about the client, but for now the subdirectories are empty. We create a client subdirectory whenever a client makes its first non-reclaim open_confirm. We remove a client subdirectory whenever either a) its lease expires, or b) the grace period ends without it reclaiming anything. When handling reclaims, we allow the reclaim if and only if the client doing the reclaim has a subdirectory. This patch adds just the code to scan the recovery directory on nfsd startup.

* [PATCH] nfsd4: fix fh_expire_typeNeilBrown2005-06-24
| | | | | | | | | | | | | | | | | | | | | | | | We're returning NFS4_FH_NOEXPIRE_WITH_OPEN | NFS4_FH_VOL_RENAME for the fh_expire_type attribute. This is incorrect: 1. The spec actually only allows NOEXPIRE_WITH_OPEN when VOLATILE_ANY is also set. 2. Filehandles for open files can expire, if the file is removed and there is a reboot. 3. Filehandles are only volatile on rename in the nosubtree check case. Unfortunately, there's no way to indicate that we only expire on remove. So our only choice is FH4_VOLATILE_ANY. Although it's redundant, we also set FH4_VOL_RENAME in the subtree check case, since subtreecheck does actually cause problems in practice and it seems possibly useful to give clients some way to distinguish that case.

* [PATCH] ipmi: add power cycle capabilityCorey Minyard2005-06-24
| | | | | | | | | | | | | | | | | | | | | | This patch to adds "power cycle" functionality to the IPMI power off module ipmi_poweroff. It also contains changes to support procfs control of the feature. The power cycle action is considered an optional chassis control in the IPMI specification. However, it is definitely useful when the hardware supports it. A power cycle is usually required in order to reset a firmware in a bad state. This action is critical to allow remote management of servers. The implementation adds power cycle as optional to the ipmi_poweroff module. It can be modified dynamically through the proc entry mentioned above. During a power down and enabled, the power cycle command is sent to the BMC firmware. If it fails either due to non-support or some error, it will retry to send the command as power off. Signed-off-by: Christopher A.

* [PATCH] Keys: Make request-key create an authorisation keyDavid Howells2005-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The attached patch makes the following changes: (1) There's a new special key type called ".request_key_auth". This is an authorisation key for when one process requests a key and another process is started to construct it. This type of key cannot be created by the user; nor can it be requested by kernel services. Authorisation keys hold two references: (a) Each refers to a key being constructed. When the key being constructed is instantiated the authorisation key is revoked, rendering it of no further use. (b) The "authorising process". This is either: (i) the process that called request_key(), or: (ii) if the process that called request_key() itself had an authorisation key in its session keyring, then the authorising process referred to by that authorisation key will also be referred to by the new authorisation key. This means that the process that initiated a chain of key requests will authorise the lot of them, and will, by default, wind up with the keys obtained from them in its keyrings. (2) request_key() creates an authorisation key which is then passed to /sbin/request-key in as part of a new session keyring. (3) When request_key() is searching for a key to hand back to the caller, if it comes across an authorisation key in the session keyring of the calling process, it will also search the keyrings of the process specified therein and it will use the specified process's credentials (fsuid, fsgid, groups) to do that rather than the calling process's credentials. This allows a process started by /sbin/request-key to find keys belonging to the authorising process. (4) A key can be read, even if the process executing KEYCTL_READ doesn't have direct read or search permission if that key is contained within the keyrings of a process specified by an authorisation key found within the calling process's session keyring, and is searchable using the credentials of the authorising process. This allows a process started by /sbin/request-key to read keys belonging to the authorising process. (5) The magic KEY_SPEC_*_KEYRING key IDs when passed to KEYCTL_INSTANTIATE or KEYCTL_NEGATE will specify a keyring of the authorising process, rather than the process doing the instantiation. (6) One of the process keyrings can be nominated as the default to which request_key() should attach new keys if not otherwise specified. This is done with KEYCTL_SET_REQKEY_KEYRING and one of the KEY_REQKEY_DEFL_* constants. The current setting can also be read using this call. (7) request_key() is partially interruptible. If it is waiting for another process to finish constructing a key, it can be interrupted. This permits a request-key cycle to be broken without recourse to rebooting.

| | | | | | | | | | | The attached patch makes it possible to pass a session keyring through to the process spawned by call_usermodehelper(). This allows patch 3/3 to pass an authorisation key through to /sbin/request-key, thus permitting better access controls when doing just-in-time key creation.

* [PATCH] keys: Discard key spinlock and use RCU for key payloadDavid Howells2005-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The attached patch changes the key implementation in a number of ways: (1) It removes the spinlock from the key structure. (2) The key flags are now accessed using atomic bitops instead of write-locking the key spinlock and using C bitwise operators. The three instantiation flags are dealt with with the construction semaphore held during the request_key/instantiate/negate sequence, thus rendering the spinlock superfluous. The key flags are also now bit numbers not bit masks. (3) The key payload is now accessed using RCU. This permits the recursive keyring search algorithm to be simplified greatly since no locks need be taken other than the usual RCU preemption disablement. Searching now does not require any locks or semaphores to be held; merely that the starting keyring be pinned. (4) The keyring payload now includes an RCU head so that it can be disposed of by call_rcu(). This requires that the payload be copied on unlink to prevent introducing races in copy-down vs search-up. (5) The user key payload is now a structure with the data following it. It includes an RCU head like the keyring payload and for the same reason. It also contains a data length because the data length in the key may be changed on another CPU whilst an RCU protected read is in progress on the payload. This would then see the supposed RCU payload and the on-key data length getting out of sync. I'm tempted to drop the key's datalen entirely, except that it's used in conjunction with quota management and so is a little tricky to get rid of. (6) Update the keys documentation.

| * [PATCH] pSeries - read irqs dynamicallyJohn Rose2005-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For I/O DLPAR to work properly, the kernel needs to allow for dynamic assignment of the irq field of the pci_dev structure upon dynamic bus addition. This patch moves the assignment of that field from pSeries_final_fixup() to pcibios_fixup_bus(), which enables dynamic assignment for the children of a newly added bus. Currently, pci_devs receive their irq numbers in one of two ways. The irq line is either read at boot for all pci_devs, or read by the rpaphp module at slot enable time. The latter is no longer sufficient for DLPAR addition of slots that don't qualify as PCI-hotplug capable. This solution handles the cases of boot and dynamic add.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pSeries_progress function is called from some places in the rtas code, which may also be used by non-pSeries platforms. Though pSeries is currently the only platform type that implements display-character, the code is actually generic enough to be part of the rtas subsystem. I hit a bug here because the generic rtas code tried calling ppc_md.progress, which points to an __init function on most platforms. We could also clear the ppc_md.progress pointer when freeing the init memory to make it more explicit that ppc_md.progress must not be called after bootup.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pSeries and maple have almost the same code for calibrate_decr, and BPA would need yet another copy. Instead, I'm moving the code to arch/ppc64/kernel/time.c. Some of the related declarations were missing from header files, so I'm moving those as well. It makes sense to merge this with the pmac function of the same name, so we end up having just one implemetation for iSeries and one for Open Firmware based machines.
