* headers: utsname.h reduxAlexey Dobriyan2009-09-23
| | | | | | | | | | | | | * remove asm/atomic.h inclusion from linux/utsname.h -- not needed after kref conversion * remove linux/utsname.h inclusion from files which do not need it NOTE: it looks like fs/binfmt_elf.c do not need utsname.h, however due to some personality stuff it _is_ needed -- cowardly leave ELF-related headers and files alone.

* SUNRPC: Allow the cache_detail to specify alternative upcall mechanismsTrond Myklebust2009-08-09
| | | | | | | | | | | | For events that are rare, such as referral DNS lookups, it makes limited sense to have a daemon constantly listening for upcalls on a channel. An alternative in those cases might simply be to run the app that fills the cache using call_usermodehelper_exec() and friends. The following patch allows the cache_detail to specify alternative upcall mechanisms for these particular cases. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* knfsd: allow cache_register to return error on failureJ. Bruce Fields2008-02-01
| | | | | | | | | | | | | Newer server features such as nfsv4 and gss depend on proc to work, so a failure to initialize the proc files they need should be treated as fatal.

* knfsd: cache unregistration needn't return errorJ. Bruce Fields2008-02-01
| | | | | | | | | | There's really nothing much the caller can do if cache unregistration fails. And indeed, all any caller does in this case is print an error and continue. So just return void and move the printk's inside cache_unregister. Acked-by: NeilBrown <neilb@suse.de> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>

* knfsd: nfsd: set rq_client to ip-address-determined-domainJ. Bruce Fields2007-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want it to be possible for users to restrict exports both by IP address and by pseudoflavor. The pseudoflavor information has previously been passed using special auth_domains stored in the rq_client field. After the preceding patch that stored the pseudoflavor in rq_pflavor, that's now superfluous; so now we use rq_client for the ip information, as auth_null and auth_unix do. However, we keep around the special auth_domain in the rq_gssclient field for backwards compatibility purposes, so we can still do upcalls using the old "gss/pseudoflavor" auth_domain if upcalls using the unix domain to give us an appropriate export. This allows us to continue supporting old mountd. In fact, for this first patch, we always use the "gss/pseudoflavor" auth_domain (and only it) if it is available; thus rq_client is ignored in the auth_gss case, and this patch on its own makes no change in behavior; that will be left to later patches. Note on idmap: I'm almost tempted to just replace the auth_domain in the idmap upcall by a dummy value--no version of idmapd has ever used it, and it's unlikely anyone really wants to perform idmapping differently depending on the where the client is (they may want to perform *credential* mapping differently, but that's a different matter--the idmapper just handles id's used in getattr and setattr). But I'm updating the idmapd code anyway, just out of general backwards-compatibility paranoia. Signed-off-by: "J.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

* [PATCH] sunrpc: cache_register can use wrong module referenceBruce Allan2005-09-07
| | | | | | | | | | | | | | | | | | | | | | | | | When registering an RPC cache, cache_register() always sets the owner as the sunrpc module. However, there are RPC caches owned by other modules. With the incorrect owner setting, the real owning module can be removed potentially with an open reference to the cache from userspace. For example, if one were to stop the nfs server and unmount the nfsd filesystem, the nfsd module could be removed eventhough rpc.idmapd had references to the idtoname and nametoid caches (i.e. /proc/net/rpc/nfs4.<cachename>/channel is still open). This resulted in a system panic on one of our machines when attempting to restart the nfs services after reloading the nfsd module. The following patch adds a 'struct module *owner' field in struct cache_detail. The owner is further assigned to the struct proc_dir_entry in cache_register() so that the module cannot be unloaded while user-space daemons have an open reference on the associated file under /proc.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
