| * | [PATCH] introduce a "kernel-internal pipe object" abstractionIngo Molnar2006-04-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | separate out the 'internal pipe object' abstraction, and make it usable to splice. This cleans up and fixes several aspects of the internal splice APIs and the pipe code: - pipes: the allocation and freeing of pipe_inode_info is now more symmetric and more streamlined with existing kernel practices. - splice: small micro-optimization: less pointer dereferencing in splice methods Signed-off-by: Ingo Molnar <mingo@elte.hu> Update XFS for the ->splice_read/->splice_write changes.

| * | [PATCH] splice: be smarter about calling do_page_cache_readahead()Jens Axboe2006-04-10
| | | | | | | | | | | | | | | | | | | | | We don't want to call into the read-ahead logic unless we are at the start of a page, _or_ we have multiple pages to read. Signed-off-by: Jens Axboe <axboe@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bugzilla Bug 6299: A pixel size of 8 bits produces wrong logo colors in x86_64. The driver has 2 methods for setting the color map, using the protected mode interface provided by the video BIOS and directly writing to the VGA registers. The former is not supported in x86_64 and the latter is enabled only in i386. Fix by enabling the latter method in x86_64 only if supported by the BIOS. If both methods are unsupported, change the visual of vesafb to STATIC_PSEUDOCOLOR.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sparc32 lacks vga.h, so lots of fbdev drivers won't compile.

* | | [PATCH] knfsd: svcrpc: WARN() instead of returning an error from svc_take_pageJ. Bruce Fields2006-04-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Every caller of svc_take_page ignores its return value and assumes it succeeded. So just WARN() instead of returning an ignored error. This would have saved some time debugging a recent nfsd4 problem. If there are still failure cases here, then the result is probably that we overwrite an earlier part of the reply while xdr-encoding. While the corrupted reply is a nasty bug, it would be worse to panic here and create the possibility of a remote DOS; hence WARN() instead of BUG(). Signed-off-by: J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In v4 we grab an extra page just for the padding of returned data.

There's no real reason to do that--the only case where rqstp->rq_cred is actually used later on is in the NFSv4 SETCLIENTID/SETCLIENTID_CONFIRM operations, and there the results are the opposite of what we want--those two operations don't deal with the filesystem at all, they only record the credentials used with the rpc call for later reference (so that we may require the same credentials be used on later operations), and the credentials shouldn't vary just because there was or wasn't a previous operation in the compound that referred to some export This fixes a bug which caused mounts from Solaris clients to fail.

I traced the problem back to svc_export_parse() calling path_release() even though path_lookup() failed (it happens to fill in the nameidata structure with a negative dentry - so the test after out: succeeds). After patching, an recreating the problem, the client mount still takes some time before finally exiting with a message "couldn't read superblock".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We should be using the length from the second vfs_getxattr, in case it changed. (Note: there's still a small race here; we could end up returning -ENOMEM if the length increased between the first and second call. I don't know whether it's worth spending a lot of effort to fix that.) This makes XFS ACLs usable on NFS exports, which they currently aren't, since XFS appears to be returning a too-large value for vfs_getxattr() when it's passed a NULL buffer. So there's probably an XFS bug here too, though since getxattr with a NULL buffer is usually used to decide how much memory to allocate, it may be a fairly harmless bug in most cases.

This is safer and more efficient. Earlier versions of this patch used a lock flag instead, but Trond pointed out that adding a new flag for each lock manager wasn't going to scale well, and suggested this approach instead; a separate patch converts lockd to using fl_lmops in the same way. In the NFSv4 case this looks like a bit of a hack, since the NFSv4 server isn't currently actually defining a lock_manager_operations struct, so we end up defining one *just* to serve as a cookie to identify our locks. But it works, and we actually do expect to start using the lock_manager_operations at some point anyway.

The units for this maximum is (4byte) words. However in three places, particularly for read request, the number given is a number of bytes. This means too much space is reserved which is slightly wasteful. This is the sort of patch that could uncover a deeper bug, and it is not critical, so it would be best for it to spend a while in -mm before going in to mainline.

* | | [PATCH] fuse: account background requestsMiklos Szeredi2006-04-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous patch removed limiting the number of outstanding requests. This patch adds a much simpler limiting, that is also compatible with file locking operations. A task may have at most one synchronous request allocated. So these requests need not be otherwise limited. However the number of background requests (release, forget, asynchronous reads, interrupted requests) can grow indefinitely. This can be used by a malicous user to cause FUSE to allocate arbitrary amounts of unswappable kernel memory, denying service. For this reason add a limit for the number of background requests, and block allocations of new requests until the number goes bellow the limit. Also use this mechanism to block all requests until the INIT reply is received.

* | | [PATCH] fuse: clean up request accountingMiklos Szeredi2006-04-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FUSE allocated most requests from a fixed size pool filled at mount time. However in some cases (release/forget) non-pool requests were used. File locking operations aren't well served by the request pool, since they may block indefinetly thus exhausting the pool. This patch removes the request pool and always allocates requests on demand.
