Greg Banks: A very significant space is missing from an "if" expression in drivers/video/Config.in.

Greg Banks: Symbols CONFIG_BLK_DEV_NS87415, CONFIG_BLK_DEV_TRM290, CONFIG_DSCC4, and CONFIG_USB_SERIAL_SAFE_PADDED had spurious (EXPERIMENTAL) tags in their banners. Symbol CONFIG_INPUT_UINPUT was missing an (EXPERIMENTAL) tag in it banner.

The mips and parisc ports both defined 'Loadable module support' menus, despite including an identical menu from init/Config.in.

Greg Banks: The symbol CONFIG_SOUND_CMPCI_FMIO is declared with a "hex" statement, immediately preceded by a "define_hex" with the same value as the default value from the "hex". In config and xconfig, this has no effect; in menuconfig it prevents the user selecting any value other than the default.

Greg Banks: The symbol CONFIG_DEBUG_SPINLOCK was defined twice identically in the same file...three lines apart.

Greg Banks: A number of dep_bools and dep_tristates have architecture constants (e.g. CONFIG_X86) as dependencies. Such symbols have the property that their value is constant for any particular arch tree, and is either "y" or "", neither of which have any effect as dependencies, so the dependencies have no effect. This patch removes some of them.

Greg Banks: The menu 'AX.25 network device drivers' contained as its first item a comment with identical banner. This is pointless duplication, but more to the point it confused gcml2 unnecessarily.

This patch simply ensures that 'setting the MTRR' is atomic. This is important since HT CPU's may share some MTRR state.

This patch makes three small changes to nfsd_readdir(). First, the 'filldir' routine for NFSv4 may return an arbitrary error, which should become the return value for nfsd_readdir(). I implemented this by adding an 'nfserr' field to the 'struct readdir_cd'. Second, in NFSv4 the caller of nfsd_readdir() will specify an attribute bitmap, which must be communicated to the 'filldir' routine. I implemented this by adding a @bitmap parameter to nfsd_readdir() and a corresponding field in the 'struct readdir_cd'. (The bitmap is not interpreted in any way by nfsd_readdir().) Finally, NFSv4 defines a new error nfserr_readdir_nospc, which indicates that there was not enough buffer space to encode a single entry.

NFSv4 defines a new field in the ACCESS response: a bitmap to indicate which access bits requested by the client are "supported", i.e. meaningful for the object in question. This patch adds a new parameter @supported to nfsd_access(), so that nfsd_access() can set the value of this bitmap.

File creation in NFSv4 is almost the same as in NFSv3, with one minor difference. If an UNCHECKED create is done, and the file exists, we don't set any attributes. Exception: If size==0 is specified as part of the attributes, then we do truncate the file, but only after processing the rest of the OPEN. (File creation is always part of an OPEN request.) This patch defines a new argument *truncp to nfsd_create_v3(), which will be NULL for v3 requests. For v4 requests, it will point to a variable which should be set to 1 if file truncation is still needed. The logic in nfsd_create_v3() is changed as follows: If - *truncp is not NULL - the create is UNCHECKED - the file exists then nfsd_create_v3() returns immediately. If size==0 is specified, then *truncp is set to 1. This is kind of a hack, but the only alternative I could see was creating a new routine nfsd_create_v4(), which would be identical to nfsd_create_v3() except for this point.

If nfsd_unlink() is called with @type equal to 0, then let it do the right thing regardless of the type of the file being unlinked. This is needed for the NFSv4 REMOVE operation, which works for any type of file, even directories.

Sanity check COMMIT arguments by ensuring that (start)+(length) < 2^64. The check is done in a way which is free of signedness pathologies in all cases. This change was inspired by pynfs, Peter Astrand's regression testsuite for NFSv4 servers. The change is necessary for all of the COMMIT tests to pass. However, it's a little open to debate whether the change is really needed. I'm curious to hear the opinions of other developers.

Change fh_compose() so that it will do the right thing if fhp==res_fh. (This is convenient in the NFSv4 LOOKUP operation, which _replaces_ CURRENT_FH with the filehandle obtained by lookup.) This requires extracting the interesting parts of the reference filehandle first, then calling fh_put if it is a re-use.
-
Kendrick M. Smith authored
When a filehandle is cleared with fh_put(), wipe out all traces by clearing ->fh_pre_saved and ->fh_post_saved. This prevents fill_post_wcc() from complaining if the filehandle is later reused. (This could happen in NFSv4 to CURRENT_FH if, for example, LOOKUP LOOKUP occurs in a COMPOUND.)

Return nfserr_nofilehandle (v4 only) in fh_verify() if the filehandle has not been set.

In a few places on the server, I had to change code that looked like: if (rqstp->rq_vers == 3) /* NFSv3 behavior */ else /* NFSv2 behavior */ to: if (rqstp->rq_vers > 2) /* NFSv3 behavior */ else /* NFSv2 behavior */ so that we would get the NFSv3 behavior, not the NFSv2 behavior, in NFSv4. This patch collects all changes of this type.

Change the type checking in fh_verify(). This fixes a bug which I reported on the mailing list a few days ago, and also adds a new error code nfserr_symlink (v4 only). This is returned whenever an operation which is illegal for symlinks is attempted on a symlink, and takes precedence over ERR_NOTDIR or ERR_INVAL.

This patch adds new NFSv4-only error codes to include/linux/nfs.h, and also indicates which of the old error codes still exist in NFSv4.

If we get here, then bio->bi_bdev isn't set, so we really shouldn't de-reference it.

..as some standard ioctls expect the per-device ioctl routine to return EINVAL and then fall back on a standard implementation.

raid1, raid5 and multipath maintain their own 'operational' flag. This is equivalent to !rdev->faulty and so isn't needed. Similarly raid1 and raid1 maintain a "write_only" flag that is equivalnt to !rdev->in_sync so it isn't needed either. As part of implementing this change, we introduce some extra flag bit in raid5 that are meaningful only inside 'handle_stripe'. Some of these replace the "action" array which recorded what actions were required (and would be performed after the stripe spinlock was released). This has the advantage of reducing our dependance on MD_SB_DISKS which personalities shouldn't need to know about.

This flag was used by multipath to make sure only one superblock was written, as there is only one real device. The relevant test is now more explicitly dependant on multipath, and the flag is gone.

Instread of the 'skip' variable, just test if rdev is NULL or not.

1/ Personalities only know about raid_disks devices. Some might be not in_sync and so cannot be read from, but must be written to. - change MD_SB_DISKS to ->raid_disks - add tests for .write_only 2/ rdev->raid_disk is now -1 for spares. desc_nr is maintained by analyse_sbs and sync_sbs. 3/ spare_inactive method is subsumed into hot_remove_disk spare_writable is subsumed into hot_add_disk. hot_add_disk decides which slot a new device will hold. 4/ spare_active now finds all non-in_sync devices and marks them in_sync. 5/ faulty devices are removed by the md recovery thread as soon as they are idle. Any spares that are available are then added.

This is equivalent to ->rdev != NULL, so it isn't needed.

This will allow us to know, in the event of a device failure, when the device is completely unused and so can be disconnected from the array. Currently this isn't a problem as drives aren't normally disconnect until after a repacement has been rebuilt, which is a LONG TIME, but that will change shortly... We always increment the count under a spinlock after checking that it hasn't been disconnected already (rdev!= NULL). We disconnect under the same spinlock after checking that the count is zero.

This simplifies the error handlers slighty, but allows for even more simplification later.

Holding the rdev instead of the bdev does cause an extra de-reference, but it is conceptually cleaner and will allow lots more tidying up.

->major_name is "const char *" so we need to sprintf into the kmalloced space *before* assigning that space to ->major_name.

1/ Raid0 should not be accessing rdev->sb. 2/ Don't unlock rdev (which releases bdev) until after last use of bdev 3/ Fix typo in a printk ( = should be -) 4/ i should be dd_idx in compute_block

bufsiz is re-evaluated on recv if SK_CHNGBUF is set, but recv will never be reached if the buffers are too small. So we have to set to to something vaguely reasonable at init time.

1/ connect requests would be get lost... As the comment at the top of svcsock.c says when discussing SK_CONN: * after a set, svc_sock_enqueue must be called. We didn't and so lost conneciton requests. 2/ set the max accept backlog to a more reasonable number to cope with bursts of lots of connection requests.
