2008-04-23SUNRPC: allow svc_recv to break out of 500ms sleep when alloc_page failsJeff Layton
svc_recv() calls alloc_page(), and if it fails it does a 500ms uninterruptible sleep and then reattempts. There doesn't seem to be any real reason for this to be uninterruptible, so change it to an interruptible sleep. Also check for kthread_stop() and signalled() after setting the task state to avoid races that might lead to sleeping after kthread_stop() wakes up the task. I've done some very basic smoke testing with this, but obviously it's hard to test the actual changes since this all depends on an alloc_page() call failing.

This adds IPv6 support to the interfaces that are used to express nfsd exports. All addressed are stored internally as IPv6; backwards compatibility is maintained using mapped addresses.

2008-04-23SUNRPC: have svc_recv() check kthread_should_stop()Jeff Layton
When using kthreads that call into svc_recv, we want to make sure that they do not block there for a long time when we're trying to take down the kthread. This patch changes svc_recv() to check kthread_should_stop() at the same places that it checks to see if it's signalled(). Also check just before svc_recv() tries to schedule(). By making sure that we check it just after setting the task state we can avoid having to use any locking or signalling to ensure it doesn't block for a long time. There's still a chance of a 500ms sleep if alloc_page() fails, but that should be a rare occurrence and isn't a terribly long time in the context of a kthread being taken down.

2008-04-22[IPSEC]: Fix catch-22 with algorithm IDs above 31Herbert Xu
As it stands it's impossible to use any authentication algorithms with an ID above 31 portably. It just happens to work on x86 but fails miserably on ppc64. The reason is that we're using a bit mask to check the algorithm ID but the mask is only 32 bits wide. After looking at how this is used in the field, I have concluded that in the long term we should phase out state matching by IDs because this is made superfluous by the reqid feature. For current applications, the best solution IMHO is to allow all algorithms when the bit masks are all ~0. The following patch does exactly that. This bug was identified by IBM when testing on the ppc64 platform using the NULL authentication algorithm which has an ID of 251.

2008-04-19[PATCH] r/o bind mounts: get callers of vfs_mknod/create/mkdir()Dave Hansen
This takes care of all of the direct callers of vfs_mknod(). Since a few of these cases also handle normal file creation as well, this also covers some calls to vfs_create(). So that we don't have to make three mnt_want/drop_write() calls inside of the switch statement, we move some of its logic outside of the switch and into a helper function suggested by Christoph. This also encapsulates a fix for mknod(S_IFREG) that Miklos found.

2008-04-18[NET]: Fix and allocate less memory for ->priv'less netdevicesAlexey Dobriyan
This patch effectively reverts commit d0498d9ae1a5cebac363e38907266d5cd2eedf89 aka "[NET]: Do not allocate unneeded memory for dev->priv alignment." It was found to be buggy because of final unconditional += NETDEV_ALIGN_CONST removal. For example, for sizeof(struct net_device) being 2048 bytes, "alloc_size" was also 2048 bytes, but allocator with debugging options turned on started giving out !32-byte aligned memory resulting in redzones overwrites. Patch does small optimization in ->priv'less case: bumping size to next 32-byte boundary was always done to ensure ->priv will also be aligned. But, no ->priv, no need to do that.

2008-04-17[NETLABEL]: Fix NULL deref in netlbl_unlabel_staticlist_gen() if ifindex not ↵Jesper Juhl
found dev_get_by_index() may return NULL if nothing is found. In net/netlabel/netlabel_unlabeled.c::netlbl_unlabel_staticlist_gen() the function is called, but the return value is never checked. If it returns NULL then we'll deref a NULL pointer on the very next line. I checked the callers, and I don't think this can actually happen today, but code changes over time and in the future it might happen and it does no harm to be defensive and check for the failure, so that if/when it happens we'll fail gracefully instead of crashing.

As I can see from the code, two places (tcp_v6_syn_recv_sock and dccp_v6_request_recv_sock) that call this one already run with BHs disabled, so it's safe to call __inet_inherit_port there. Besides (in case I missed smth with code review) the calltrace tcp_v6_syn_recv_sock `- tcp_v4_syn_recv_sock `- __inet_inherit_port and the similar for DCCP are valid, but assumes BHs to be disabled.

2008-04-16IB/core: Add support for "send with invalidate" work requestsRoland Dreier
Add a new IB_WR_SEND_WITH_INV send opcode that can be used to mark a "send with invalidate" work request as defined in the iWARP verbs and the InfiniBand base memory management extensions. Also put "imm_data" and a new "invalidate_rkey" member in a new "ex" union in struct ib_send_wr. The invalidate_rkey member can be used to pass in an R_Key/STag to be invalidated. Add this new union to struct ib_uverbs_send_wr. Add code to copy the invalidate_rkey field in ib_uverbs_post_send(). Fix up low-level drivers to deal with the change to struct ib_send_wr, and just remove the imm_data initialization from net/sunrpc/xprtrdma/, since that code never does any send with immediate operations. Also, move the existing IB_DEVICE_SEND_W_INV flag to a new bit, since the iWARP drivers currently in the tree set the bit. The amso1100 driver at least will silently fail to honor the IB_SEND_INVALIDATE bit if passed in as part of userspace send requests (since it does not implement kernel bypass work request queueing). Remove the flag from all existing drivers that set it until we know which ones are OK. The values chosen for the new flag is not consecutive to avoid clashing with flags defined in the XRC patches, which are not merged yet but which are already in use and are likely to be merged soon.
