I noticed that we export a way to high value for the maxfilesize attribute when debugging a client issue. The issue didn't turn out to be related to it, but I think we should export it, so that clients can limit what write sizes they accept before hitting the server.

Currently the rpc code conservatively refuses to accept rpc's from a client if the sum of its worst-case estimates of the replies it owes that client exceed the send buffer space. Unfortunately our estimate of the worst-case reply for an NFSv4 compound is always the maximum read size. This can unnecessarily limit the number of operations we handle concurrently, for example in the case most operations are writes (which have small replies). We can do a little better if we check which ops the compound contains. This is still a rough estimate, we'll need to improve on it some day.

The server does allow NFS over v4.2, even if it doesn't add any new operations yet.

We were using a different array of function pointers to represent each minor version. This makes adding a new minor version tedious, since it needs a step to copy, paste and modify a new version of the same functions. This patch combines the v4 and v4.1 arrays into a single instance and will check minor version support inside each decoder function.

If we're going to refuse to accept these it would be polite of us to at least say so.... This introduces a slight complication since we need to grandfather in exportfs's ill-advised use of -1 uid and gid on its test_export. If it turns out there are other users passing down -1 we may need to do something else. Best might be to drop the checks entirely, but I'm not sure if other parts of the kernel might assume that a task can't run as uid or gid -1. Cc: "Eric W.

The reporter saw a NULL dereference when a filesystem's ->mknod returned success but left the dentry negative, and then nfsd tried to dereference d_inode (in this case because the CREATE was followed by a GETATTR in the same nfsv4 compound). fh_update already checks for this and another broken case, but for some reason it returns success and leaves nfsd trying to soldier on. If it failed we'd avoid the crash. There's only so much we can do with a buggy filesystem, but it's easy enough to bail out here, so let's do that.

As Bruce points out in RFC 4121, section 4.2.3: "In Wrap tokens that provide for confidentiality, the first 16 octets of the Wrap token (the "header", as defined in section 4.2.6), SHALL be appended to the plaintext data before encryption. Filler octets MAY be inserted between the plaintext data and the "header."" ...and... "In Wrap tokens with confidentiality, the EC field SHALL be used to encode the number of octets in the filler..." It's possible for the client to stuff different data in that area on a retransmission, which could make the checksum come out wrong in the DRC code. After decrypting the blob, we should trim off any extra count bytes in addition to the checksum blob. Reported-by: N"J.

Ben Herrenschmidt found that commit 928bea96 ("PCI: Delay enabling bridges until they're needed") breaks PCI in some powerpc environments. The reason is that the PCIe port driver will call pci_enable_device() on the bridge, so the device is enabled, but skips pci_set_master because pcie_port_auto and no acpi on powerpc. Because of that, pci_enable_bridge() later on (called as a result of the child device driver doing pci_enable_device) will see the bridge as already enabled and will not call pci_set_master() on it. Fixed by add checking in pci_enable_bridge, and call pci_set_master if driver skip that. That will make the code more robot and wade off problem for missing pci_set_master in drivers.
