Allowing simple, safe,\nwell understood work-arounds to known problematic software.\n\nThis also addresses a rare but unfortunate problem where the filesystem\nname is not the same as it\u0027s module name and module auto-loading\nwould not work. While writing this patch I saw a handful of such\ncases. The most significant being autofs that lives in the module\nautofs4.\n\nThis is relevant to user namespaces because we can reach the request\nmodule in get_fs_type() without having any special permissions, and\npeople get uncomfortable when a user specified string (in this case\nthe filesystem type) goes all of the way to request_module.\n\nAfter having looked at this issue I don\u0027t think there is any\nparticular reason to perform any filtering or permission checks beyond\nmaking it clear in the module request that we want a filesystem\nmodule. The common pattern in the kernel is to call request_module()\nwithout regards to the users permissions. In general all a filesystem\nmodule does once loaded is call register_filesystem() and go to sleep.\nWhich means there is not much attack surface exposed by loading a\nfilesytem module unless the filesystem is mounted.

If a kernel panic happens in an interrupt context,\nit may fail because it could sleep due to dynamic memory allocations during\ncreating sysfs entries.\n\n[Patch Description]\nThis patch removes sysfs operations from a write callback by introducing\na workqueue updating sysfs entries which is scheduled after the write\ncallback is called.\n\nAlso, the workqueue is kicked in a just oops case.\nA system will go down in other cases such as panic, clean shutdown and emergency\nrestart. And we don\u0027t need to create sysfs entries because there is no chance for\nusers to access to them.\n\nefi_pstore will be robust against a kernel panic in an interrupt context with this patch.\n\nSigned-off-by: Seiji Aguchi \u003cseiji.aguchi@hds.com\u003e\nAcked-by: Matt Fleming \u003cmatt.fleming@intel.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "81fa4e581d9283f7992a0d8c534bb141eb840a14", "tree": "2bc7677534c1cef8dfb5388059777bfb1164e66c", "parents": [ "e59310adf5eebce108f78b6c47bb330aae2e1666" ], "author": { "name": "Seiji Aguchi", "email": "seiji.aguchi@hds.com", "time": "Tue Feb 12 12:59:07 2013 -0800" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Tue Feb 12 12:59:07 2013 -0800" }, "message": "efivars: Disable external interrupt while holding efivars-\u003elock\n\n[Problem]\nThere is a scenario which efi_pstore fails to log messages in a panic case.\n\n - CPUA holds an efi_var-\u003elock in either efivarfs parts\n or efi_pstore with interrupt enabled.\n - CPUB panics and sends IPI to CPUA in smp_send_stop().\n - CPUA stops with holding the lock.\n - CPUB kicks efi_pstore_write() via kmsg_dump(KSMG_DUMP_PANIC)\n but it returns without logging messages.\n\n[Patch Description]\nThis patch disables an external interruption while holding efivars-\u003elock\nas follows.\n\nIn efi_pstore_write() and get_var_data(), spin_lock/spin_unlock is\nreplaced by spin_lock_irqsave/spin_unlock_irqrestore because they may\nbe called in an interrupt context.\n\nIn other functions, they are replaced by spin_lock_irq/spin_unlock_irq.\nbecause they are all called from a process context.\n\nBy applying this patch, we can avoid the problem above with\na following senario.\n\n - CPUA holds an efi_var-\u003elock with interrupt disabled.\n - CPUB panics and sends IPI to CPUA in smp_send_stop().\n - CPUA receives the IPI after releasing the lock because it is\n disabling interrupt while holding the lock.\n - CPUB waits for one sec until CPUA releases the lock.\n - CPUB kicks efi_pstore_write() via kmsg_dump(KSMG_DUMP_PANIC)\n And it can hold the lock successfully.\n\nSigned-off-by: Seiji Aguchi \u003cseiji.aguchi@hds.com\u003e\nAcked-by: Mike Waychison \u003cmikew@google.com\u003e\nAcked-by: Matt Fleming \u003cmatt.fleming@intel.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "da27a24383b2b10bf6ebd0db29b325548aafecb4", "tree": "db48f001f62af527e832fe2c1cd302b30e794b6a", "parents": [ "47f531e8ba3bc3901a0c493f4252826c41dea1a1" ], "author": { "name": "Matt Fleming", "email": "matt.fleming@intel.com", "time": "Fri Feb 01 11:02:28 2013 +0000" }, "committer": { "name": "Matt Fleming", "email": "matt.fleming@intel.com", "time": "Tue Feb 12 12:41:54 2013 +0000" }, "message": "efivarfs: guid part of filenames are case-insensitive\n\nIt makes no sense to treat the following filenames as unique,\n\n\tVarName-abcdefab-abcd-abcd-abcd-abcdefabcdef\n\tVarName-ABCDEFAB-ABCD-ABCD-ABCD-ABCDEFABCDEF\n\tVarName-ABcDEfAB-ABcD-ABcD-ABcD-ABcDEfABcDEf\n\tVarName-aBcDEfAB-aBcD-aBcD-aBcD-aBcDEfaBcDEf\n\t... etc ...\n\nsince the guid will be converted into a binary representation, which\nhas no case.\n\nRoll our own dentry operations so that we can treat the variable name\npart of filenames (\"VarName\" in the above example) as case-sensitive,\nbut the guid portion as case-insensitive.

Over time its semantics have changed, and it now\nindicates whether or not we are booted on an EFI machine with\nbit-native firmware, e.g. 64-bit kernel with 64-bit firmware.\n\nThe immediate motivation for this patch is the bug report at,\n\n https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557\n\nwhich details how running a platform driver on an EFI machine that is\ndesigned to run under BIOS can cause the machine to become\nbricked. Also, the following report,\n\n https://bugzilla.kernel.org/show_bug.cgi?id\u003d47121\n\ndetails how running said driver can also cause Machine Check\nExceptions.

There are also checks in some of the platform\ndriver code to simply see if they\u0027re running on an EFI machine (which\nwould make it a bad idea to do BIOS-y things).\n\nThis patch is a prereq for the samsung-laptop fix patch.\n\nCc: David Airlie \u003cairlied@linux.ie\u003e\nCc: Corentin Chary \u003ccorentincj@iksaif.net\u003e\nCc: Matthew Garrett \u003cmjg59@srcf.ucam.org\u003e\nCc: Dave Jiang \u003cdave.jiang@intel.com\u003e\nCc: Olof Johansson \u003colof@lixom.net\u003e\nCc: Peter Jones \u003cpjones@redhat.com\u003e\nCc: Colin Ian King \u003ccolin.king@canonical.com\u003e\nCc: Steve Langasek \u003csteve.langasek@canonical.com\u003e\nCc: Tony Luck \u003ctony.luck@intel.com\u003e\nCc: Konrad Rzeszutek Wilk \u003ckonrad@kernel.org\u003e\nCc: Rafael J.
