This means that the EFI\nitem is never freed if it was in the push being cancelled. The\nproblem is specific to delayed logging, but has uncovered a couple\nof problems with the handling of IOP_UNPIN(remove).\n\nFirstly, we cannot safely call xfs_trans_del_item() from IOP_UNPIN()\nin the CIL commit failure path or the iclog write failure path\nbecause for delayed loging we have no transaction context. Hence we\nmust only call xfs_trans_del_item() if the log item being unpinned\nhas an active log item descriptor.\n\nSecondly, xfs_trans_uncommit() does not handle log item descriptor\nfreeing during the traversal of log items on a transaction. It can\nreference a freed log item descriptor when unpinning an EFI item.\nHence it needs to use a safe list traversal method to allow items to\nbe removed from the transaction during IOP_UNPIN().\n\nSigned-off-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nReviewed-by: Alex Elder \u003caelder@sgi.com\u003e\n" }, { "commit": "b12ece7d852efbc8db45371c068900fcc62002d4", "tree":

One thing containers can isolate is\n\"network namespaces\", meaning each container can have its own set of\nethernet interfaces, each with its own own IP address and routing to the\noutside world. And if you open a socket in _userspace_ from processes\nwithin such a container, this works fine.\n\nBut sockets opened from within the kernel still use a single global\nnetworking context in a lot of places, meaning the new socket\u0027s address\nand routing are correct for PID 1 on the host, but are _not_ what\nuserspace processes in the container get to use.\n\nSo when you mount a network filesystem from within in a container, the\nmount code in the CIFS driver uses the host\u0027s networking context and not\nthe container\u0027s networking context, so it gets the wrong address, uses\nthe wrong routing, and may even try to go out an interface that the\ncontainer can\u0027t even access... Bad stuff.\n\nThis patch copies the mount process\u0027s network context into the CIFS\nstructure that stores the rest of the server information for that mount\npoint, and changes the socket open code to use the saved network context\ninstead of the global network context. I.E. \"when you attempt to use\nthese addresses, do so relative to THIS set of network interfaces and\nrouting rules, not the old global context from back before we supported\ncontainers\".\n\nThe big long HOWTO sets up a test environment on the assumption you\u0027ve\nnever used ocntainers before. It basically says:\n\n1) configure and build a new kernel that has container support\n2) build a new root filesystem that includes the userspace container\ncontrol package (LXC)\n3) package/run them under KVM (so you don\u0027t have to mess up your host\nsystem in order to play with containers).\n4) set up some containers under the KVM system\n5) set up contradictory routing in the KVM system and the container so\nthat the host and the container see different things for the same address\n6) try to mount a CIFS share from both contexts so you can both force it\nto work and force it to fail.\n\nFor a long drawn out test reproduction sequence, see:\n\n http://landley.livejournal.com/47024.html\n http://landley.livejournal.com/47205.html\n http://landley.livejournal.com/47476.html\n\nSigned-off-by: Rob Landley \u003crlandley@parallels.com\u003e\nReviewed-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nSigned-off-by: Steve French \u003csfrench@us.ibm.com\u003e\n" }, { "commit": "3f391c79b0686ce183668c6e2b7d02f3e716766c", "tree": "304cdb0d55dd84fccfffaf281ff9f06c265a138c", "parents": [ "1bae4ce27c9c90344f23c65ea6966c50ffeae2f5" ], "author": { "name": "Jesper Juhl", "email": "jj@chaosbits.net", "time": "Sat Jan 22 21:07:16 2011 +0100" }, "committer": { "name": "Steve French", "email": "sfrench@us.ibm.com", "time": "Mon Jan 24 03:32:01 2011 +0000" }, "message": "CIFS: Remove pointless variable assignment in cifs_dfs_do_automount()\n\nIn fs/cifs/cifs_dfs_ref.c::cifs_dfs_do_automount() we have this code:\n\n\t...\n\tmnt \u003d ERR_PTR(-EINVAL);\n\tif (IS_ERR(tlink)) {\n\t\tmnt \u003d ERR_CAST(tlink);\n\t\tgoto free_full_path;\n\t}\n\tses \u003d tlink_tcon(tlink)-\u003eses;\n\n\trc \u003d get_dfs_path(xid, ses, full_path + 1, cifs_sb-\u003elocal_nls,\n\t\t\u0026num_referrals, \u0026referrals,\n\t\tcifs_sb-\u003emnt_cifs_flags \u0026 CIFS_MOUNT_MAP_SPECIAL_CHR);\n\n\tcifs_put_tlink(tlink);\n\n\tmnt \u003d ERR_PTR(-ENOENT);\n\t...\n\nThe assignment of \u0027mnt \u003d ERR_PTR(-EINVAL);\u0027 is completely pointless.

If we time out requests and issue spurious disconnects then that\ncomprimises data integrity.\n\nInstead of doing this complicated dance where we try to decide how long\nto wait for a response for particular requests, have the client instead\nwait indefinitely for a response. Also, use a TASK_KILLABLE sleep here\nso that fatal signals will break out of this waiting.\n\nLater patches will add support for detecting dead peers and forcing\nreconnects based on that.\n\nReviewed-by: Suresh Jayaraman \u003csjayaraman@suse.de\u003e\nReviewed-by: Pavel Shilovsky \u003cpiastryyy@gmail.com\u003e\nSigned-off-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nSigned-off-by: Steve French \u003csfrench@us.ibm.com\u003e\n" }, { "commit": "2fbc2f1729e785a7b2faf9d8d60926bb1ff62af0", "tree": "4665c741041553259b626df604e617879440fb53", "parents": [ "540b2e377797d8715469d408b887baa9310c5f3e" ], "author": { "name": "Shirish Pargaonkar", "email": "shirishpargaonkar@gmail.com", "time": "Mon Dec 06 14:56:46 2010 -0600" }, "committer": { "name": "Steve French", "email": "sfrench@us.ibm.com", "time": "Wed Jan 19 21:25:58 2011 +0000" }, "message": "cifs: Use mask of ACEs for SID Everyone to calculate all three permissions user, group, and other\n\nIf a DACL has entries for ACEs for SID Everyone and Authenticated Users,\nfactor in mask in respective entries during calculation of permissions\nfor all three, user, group, and other.\n\nhttp://technet.microsoft.com/en-us/library/bb463216.aspx\n\nSigned-off-by: Shirish Pargaonkar \u003cshirishpargaonkar@gmail.com\u003e\nReviewed-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nSigned-off-by: Steve French \u003csfrench@us.ibm.com\u003e\n" }, { "commit": "0da2a4ac33c291728d8be5bdb865467dcb078d13", "tree": "7f6af191fa9020a8d4bd0cdb828fd15fecd39411", "parents": [ "c56eb8fb6dccb83d9fe62fd4dc00c834de9bc470" ], "author": { "name": "Fred Isaman", "email": "iisaman@netapp.com", "time": "Wed Jan 19 14:18:50 2011 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Jan 19 15:37:49 2011 -0500" }, "message": "NFS: fix handling of malloc failure during nfs_flush_multi()\n\nCleanup of the allocated list entries should not call\nput_nfs_open_context() on each entry, as the context will\nalways be NULL, causing an oops.\n\nSigned-off-by: Fred Isaman \u003ciisaman@netapp.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "540b2e377797d8715469d408b887baa9310c5f3e", "tree": "50f37a5ffc2bd27d70f59a9b592ba0d29e22bfda", "parents": [ "1cd3508d5eab6a88fa643119cedd34b04215cffe" ], "author": { "name": "Shirish Pargaonkar", "email": "shirishpargaonkar@gmail.com", "time": "Tue Jan 18 22:33:54 2011 -0600" }, "committer": { "name": "Steve French", "email": "sfrench@us.ibm.com", "time": "Wed Jan 19 18:11:18 2011 +0000" }, "message": "cifs: Fix regression during share-level security mounts (Repost)\n\nNTLM response length was changed to 16 bytes instead of 24 bytes\nthat are sent in Tree Connection Request during share-level security\nshare mounts.
