This patch generalises the TSO-specific bits from sk_setup_caps by adding the sk_gso_type member to struct sock. This makes sk_setup_caps generic so that it can be used by TCPv6 or UFO. The only catch is that whoever uses this must provide a GSO implementation for their protocol which I think is a fair deal :) For now UFO continues to live without a GSO implementation which is OK since it doesn't use the sock caps field at the moment.

We don't need to check skb->len when we're just about to call pskb_may_pull since that checks it for us. Signed-off-by:

When a packet without any chunks is received, the newconntrack variable in sctp_packet contains an out of bounds value that is used to look up an pointer from the array of timeouts, which is then dereferenced, resulting in a crash. Make sure at least a single chunk is present. Problem noticed by George A. Theall <theall@tenablesecurity.com> Signed-off-by:

Use GSO to workaround a rare TSO bug on some chips. This hardware bug may be triggered when the TSO header size is greater than 80 bytes. When this condition is detected in a TSO packet, the driver will use GSO to segment the packet to workaround the hardware bug. Thanks to Juergen Kreileder <jk@blackdown.de> for reporting the problem and collecting traces to help debug the problem. And thanks to Herbert Xu <herbert@gondor.apana.org.au> for providing the GSO mechanism that happens to be the perfect workaround for this problem. Signed-off-by:

I wasn't paranoid enough in verifying GSO information. A bogus gso_segs could upset drivers as much as a bogus header would. Let's reset it in the per-protocol gso_segment functions. I didn't verify gso_size because that can be verified by the source of the dodgy packets. Signed-off-by:

Add a rq_sendfile_ok flag to svc_rqst which will be cleared in the privacy case so that the wrapping code will get copies of the read data instead of real page cache pages. This makes life simpler when we encrypt the response. Signed-off-by:

Since nfsv4 actually keeps around the file descriptors it gets from open (instead of just using them for a single read or write operation), we need to make sure that we can do RDWR opens and not just RDONLY/WRONLY. Signed-off-by:

In the event that lookup_one_len() fails in nfsd_link(), fh_unlock() is skipped and locks are held overlong. Patch was tested on 2.6.17-rc2 by causing lookup_one_len() to fail and verifying that fh_unlock() gets called appropriately. Signed-off-by:

In the typical v2/v3 case the only new filehandles used as arguments to operations are filehandles taken directly off the wire, which don't get dentries until fh_verify() is called. But in v4 the filehandles that are arguments to operations were often created by previous operations (putrootfh, lookup, etc.) using fh_compose, which sets the dentry in the filehandle without calling nfsd_setuser(). This also means that, for example, if filesystem B is mounted on filesystem A, and filesystem A is exported without root-squashing, then a client can bypass the rootsquashing on B using a compound that starts at a filehandle in A, crosses into B using lookups, and then does stuff in B.

nfsd tries to return to a client the same sort of filehandle as was used by the client. This removes some filehandle aliasing issues and means that a server upgrade followed by a downgrade will not confused clients not restarted during that time. However when crossing a mountpoint, the filehandle used for one filesystem doesn't provide any useful information on what sort of filehandle should be used on the other, and can provide misleading information. So if the reference filehandle is on a different filesystem to the one being generated, ignore it. Signed-off-by:

There is a perfectly valid situation where fh_update gets called on an already uptodate filehandle - in nfsd_create_v3 where a CREATE_UNCHECKED finds an existing file and wants to just set the size. We could possible optimise out the call in that case, but the only harm involved is that fh_update prints a warning, so it is easier to remove the warning. Signed-off-by:

Type '3' is used for the fsid in filehandles when the device number of the device holding the filesystem has more than 8 bits in either major or minor. Unfortunately expkey_parse doesn't recognise type 3. Fix this. (Slighty modified from Frank's original) Signed-off-by:

Remove add_mc_to_global_list(). In next patch, this function will be reimplemented with different semantics. 1 Reimplement add_mc_to_global_list() with semantics that allow the caller to determine the ID number for a mem_ctl_info structure. Then modify edac_mc_add_mc() so that the caller specifies the ID number for the new mem_ctl_info structure. Platform-specific code should be able to assign the ID numbers in a platform-specific manner. For instance, on Opteron it makes sense to have the ID of the mem_ctl_info structure match the ID of the node that the memory controller belongs to. 2 Modify callers of edac_mc_add_mc() so they use the new semantics.

Change MC drivers from using CVS revision strings for their version number, Now each driver has its own local string. Remove some PCI dependencies from the core EDAC module. Made the code 'struct device' centric instead of 'struct pci_dev' Most of the code changes here are from a patch by Dave Jiang. It may be best to eventually move the PCI-specific code into a separate source file. Signed-off-by:

Fix a bug identified by Zou Nan hai <nanhai.zou@intel.com>: If the system is in state SYSTEM_BOOTING, and need_resched() is true, cond_resched() returns true even though it didn't reschedule. Consequently need_resched() remains true and JBD locks up. Fix that by teaching cond_resched() to only return true if it really did call schedule(). cond_resched_lock() and cond_resched_softirq() have a problem too. If we're in SYSTEM_BOOTING state and need_resched() is true, these functions will drop the lock and will then try to call schedule(), but the SYSTEM_BOOTING state will prevent schedule() from being called. So on return, need_resched() will still be true, but cond_resched_lock() has to return 1 to tell the caller that the lock was dropped. The caller will probably lock up. Bottom line: if these functions dropped the lock, they _must_ call schedule() to clear need_resched(). Make it so. Also, uninline __cond_resched(). It's largeish, and slowpath. Acked-by:

I run an x86_64 kernel with i386 userspace (Ubuntu Dapper) and decided to try out UML today. I found that UML wasn't quite aware of biarch compilers (which Ubuntu i386 ships). A fix similar to what was done for x86_64 should probably be committed (see http://marc.theaimsgroup.com/?l=linux-kernel&m=113425940204010&w=2). Without the FLAGS changes, the build will fail at a number of places and without the LINK change, the final link will fail. Signed-off-by:
