Among other things,\nthis commit changes the default mount options for NFSROOT to use TCP\ninstead of UDP as the underlying transport.\n\nTCP seems less able to deal with NICs that are slow to initialize.\nThe system logs that have accompanied reports of problems all show\nthat NFSROOT attempts to establish a TCP connection before the NIC is\nfully initialized, and thus the TCP connection attempt fails.\n\nWhen a TCP connection attempt fails during a mount operation, the\nNFS stack needs to fail the operation. Usually user space knows how\nand when to retry it. The network layer does not report a distinct\nerror code for this particular failure mode. Thus, there isn\u0027t a\nclean way for the RPC client to see that it needs to retry in this\ncase, but not in others.\n\nBecause NFSROOT is used in some environments where it is not possible\nto update the kernel command line to specify \"udp\", the proper thing\nto do is change NFSROOT to use UDP by default, as it did before commit\n56463e50.\n\nTo make it easier to see how to change default mount options for\nNFSROOT and to distinguish default settings from mandatory settings,\nI\u0027ve adjusted a couple of areas to document the specifics.\n\nroot_nfs_cat() is also modified to deal with commas properly when\nconcatenating strings containing mount option lists. This keeps\nroot_nfs_cat() call sites simpler, now that we may be concatenating\nmultiple mount option strings.\n\nTested-by: Brian Downing \u003cbdowning@lavos.net\u003e\nTested-by: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nCc: \u003cstable@kernel.org\u003e # 2.6.37\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "57df216bd8c8813a79a6a618e3d2ec937d532b86", "tree": "ee3eddc164a7a1942a3239883336f90eeab6ee62", "parents": [ "f9feab1e180d1392f2f59d692826c6da2e57adf4" ], "author": { "name": "Huang Weiyi", "email": "weiyi.huang@gmail.com", "time": "Tue Mar 08 23:11:30 2011 +0000" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Mar 11 15:18:37 2011 -0500" }, "message": "nfs4: remove duplicated #include\n\nRemove duplicated #include(\u0027s) in\n fs/nfs/nfs4proc.c\n\nSigned-off-by: Huang Weiyi \u003cweiyi.huang@gmail.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "f9feab1e180d1392f2f59d692826c6da2e57adf4", "tree": "1af4e0012ddb1d74b0cd44fc4461bd5b78f5adf5", "parents": [ "ecac799a5ecc364006f0db6f2db15e77ed4d63e2" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Mar 09 16:12:46 2011 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Mar 11 15:18:36 2011 -0500" }, "message": "NFSv4: nfs4_state_mark_reclaim_nograce() should be static\n\nThere are no more external users of nfs4_state_mark_reclaim_nograce() or\nnfs4_state_mark_reclaim_reboot(), so mark them as static.\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "ecac799a5ecc364006f0db6f2db15e77ed4d63e2", "tree": "200a71e8c3d564bb26e31cda2c4283142c380ee7", "parents": [ "b4410c2f7f775b03da31566c05bb8d2383c7dc27" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Mar 09 16:00:56 2011 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Mar 11 15:18:36 2011 -0500" }, "message": "NFSv4: Fix the setlk error handler\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "b4410c2f7f775b03da31566c05bb8d2383c7dc27", "tree": "7d16c41557c7aa17489a222a660ad71bd7fb370b", "parents": [ "0400a6b0cb756f976bae32ae8db47bfa9853897c" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Mar 09 16:00:55 2011 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Mar 11 15:18:35 2011 -0500" }, "message": "NFSv4.1: Fix the handling of the SEQUENCE status bits\n\nWe want SEQUENCE status bits to be handled by the state manager in order\nto avoid threading issues.\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "0400a6b0cb756f976bae32ae8db47bfa9853897c", "tree": "ec1393f7e5eeec02a0cc4504d98a138ae458f443", "parents": [ "c34c32ea97718bb24fc06158733580003ba89211" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Mar 09 16:00:53 2011 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Mar 11 15:18:22 2011 -0500" }, "message": "NFSv4/4.1: Fix nfs4_schedule_state_recovery abuses\n\nnfs4_schedule_state_recovery() should only be used when we need to force\nthe state manager to check the lease.

This means that when we\nexit, we want all references to the rpc_task to be gone, and we want\nany dentry references etc. held by that task to be released.\n\nFor this reason these functions call __rpc_wait_for_completion_task(),\nfollowed by rpc_put_task() in the expectation that the latter will be\nreleasing the last reference to the rpc_task, and thus ensuring that the\ncallback_ops-\u003erpc_release() has been called synchronously.\n\nThis patch fixes a race which exists due to the fact that\nrpciod calls rpc_complete_task() (in order to wake up the callers of\n__rpc_wait_for_completion_task()) and then subsequently calls\nrpc_put_task() without ensuring that these two steps are done atomically.\n\nIn order to avoid adding new spin locks, the patch uses the existing\nwaitqueue spin lock to order the rpc_task reference count releases between\nthe waiting process and rpciod.\nThe common case where nobody is waiting for completion is optimised for by\nchecking if the RPC_TASK_ASYNC flag is cleared and/or if the rpc_task\nreference count is 1: in those cases we drop trying to grab the spin lock,\nand immediately free up the rpc_task.\n\nThose few processes that need to put the rpc_task from inside an\nasynchronous context and that do not care about ordering are given a new\nhelper: rpc_put_task_async().\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "e9e3d724e2145f5039b423c290ce2b2c3d8f94bc", "tree": "9b0ff4de361fe358a5a2400b35a48206688b5f71", "parents": [ "3256f80fbbc25bd2504bd564844c615227621e56" ], "author": { "name": "Neil Horman", "email": "nhorman@tuxdriver.com", "time": "Fri Mar 04 19:26:03 2011 -0500" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 04 17:28:52 2011 -0800" }, "message": "nfs4: Ensure that ACL pages sent over NFS were not allocated from the slab (v3)\n\nThe \"bad_page()\" page allocator sanity check was reported recently (call\nchain as follows):\n\n bad_page+0x69/0x91\n free_hot_cold_page+0x81/0x144\n skb_release_data+0x5f/0x98\n __kfree_skb+0x11/0x1a\n tcp_ack+0x6a3/0x1868\n tcp_rcv_established+0x7a6/0x8b9\n tcp_v4_do_rcv+0x2a/0x2fa\n tcp_v4_rcv+0x9a2/0x9f6\n do_timer+0x2df/0x52c\n ip_local_deliver+0x19d/0x263\n ip_rcv+0x539/0x57c\n netif_receive_skb+0x470/0x49f\n :virtio_net:virtnet_poll+0x46b/0x5c5\n net_rx_action+0xac/0x1b3\n __do_softirq+0x89/0x133\n call_softirq+0x1c/0x28\n do_softirq+0x2c/0x7d\n do_IRQ+0xec/0xf5\n default_idle+0x0/0x50\n ret_from_intr+0x0/0xa\n default_idle+0x29/0x50\n cpu_idle+0x95/0xb8\n start_kernel+0x220/0x225\n _sinittext+0x22f/0x236\n\nIt occurs because an skb with a fraglist was freed from the tcp\nretransmit queue when it was acked, but a page on that fraglist had\nPG_Slab set (indicating it was allocated from the Slab allocator (which\nmeans the free path above can\u0027t safely free it via put_page.\n\nWe tracked this back to an nfsv4 setacl operation, in which the nfs code\nattempted to fill convert the passed in buffer to an array of pages in\n__nfs4_proc_set_acl, which gets used by the skb-\u003efrags list in\nxs_sendpages. __nfs4_proc_set_acl just converts each page in the buffer\nto a page struct via virt_to_page, but the vfs allocates the buffer via\nkmalloc, meaning the PG_slab bit is set. We can\u0027t create a buffer with\nkmalloc and free it later in the tcp ack path with put_page, so we need\nto either:\n\n1) ensure that when we create the list of pages, no page struct has\n PG_Slab set\n\n or\n\n2) not use a page list to send this data\n\nGiven that these buffers can be multiple pages and arbitrarily sized, I\nthink (1) is the right way to go. I\u0027ve written the below patch to\nallocate a page from the buddy allocator directly and copy the data over\nto it. This ensures that we have a put_page free-able page for every\nentry that winds up on an skb frag list, so it can be safely freed when\nthe frame is acked. We do a put page on each entry after the\nrpc_call_sync call so as to drop our own reference count to the page,\nleaving only the ref count taken by tcp_sendpages. This way the data\nwill be properly freed when the ack comes in\n\nSuccessfully tested by myself to solve the above oops.\n\nNote, as this is the result of a setacl operation that exceeded a page\nof data, I think this amounts to a local DOS triggerable by an\nuprivlidged user, so I\u0027m CCing security on this as well.\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nCC: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\nCC: security@kernel.org\nCC: Jeff Layton \u003cjlayton@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" } ], "next": "43d133c18b44e7d82d82ef0dcc2bddd55d5dfe81" }
