Changes are made to the new credentials, rather\n \t than the task itself as in security_task_post_setuid().\n\n (*) security_task_reparent_to_init(), -\u003etask_reparent_to_init()\n\n \t Removed. Instead the task being reparented to init is referred\n \t directly to init\u0027s credentials.\n\n\t NOTE! This results in the loss of some state: SELinux\u0027s osid no\n\t longer records the sid of the thread that forked it.\n\n (*) security_key_alloc(), -\u003ekey_alloc()\n (*) security_key_permission(), -\u003ekey_permission()\n\n \t Changed. These now take cred pointers rather than task pointers to\n \t refer to the security context.\n\n (4) sys_capset().\n\n This has been simplified and uses less locking. The LSM functions it\n calls have been merged.\n\n (5) reparent_to_kthreadd().\n\n This gives the current thread the same credentials as init by simply using\n commit_thread() to point that way.\n\n (6) __sigqueue_alloc() and switch_uid()\n\n __sigqueue_alloc() can\u0027t stop the target task from changing its creds\n beneath it, so this function gets a reference to the currently applicable\n user_struct which it then passes into the sigqueue struct it returns if\n successful.\n\n switch_uid() is now called from commit_creds(), and possibly should be\n folded into that. commit_creds() should take care of protecting\n __sigqueue_alloc().\n\n (7) [sg]et[ug]id() and co and [sg]et_current_groups.\n\n The set functions now all use prepare_creds(), commit_creds() and\n abort_creds() to build and check a new set of credentials before applying\n it.\n\n security_task_set[ug]id() is called inside the prepared section. This\n guarantees that nothing else will affect the creds until we\u0027ve finished.\n\n The calling of set_dumpable() has been moved into commit_creds().\n\n Much of the functionality of set_user() has been moved into\n commit_creds().\n\n The get functions all simply access the data directly.\n\n (8) security_task_prctl() and cap_task_prctl().\n\n security_task_prctl() has been modified to return -ENOSYS if it doesn\u0027t\n want to handle a function, or otherwise return the return value directly\n rather than through an argument.\n\n Additionally, cap_task_prctl() now prepares a new set of credentials, even\n if it doesn\u0027t end up using it.\n\n (9) Keyrings.\n\n A number of changes have been made to the keyrings code:\n\n (a) switch_uid_keyring(), copy_keys(), exit_keys() and suid_keys() have\n \t all been dropped and built in to the credentials functions directly.\n \t They may want separating out again later.\n\n (b) key_alloc() and search_process_keyrings() now take a cred pointer\n \t rather than a task pointer to specify the security context.\n\n (c) copy_creds() gives a new thread within the same thread group a new\n \t thread keyring if its parent had one, otherwise it discards the thread\n \t keyring.\n\n (d) The authorisation key now points directly to the credentials to extend\n \t the search into rather pointing to the task that carries them.\n\n (e) Installing thread, process or session keyrings causes a new set of\n \t credentials to be created, even though it\u0027s not strictly necessary for\n \t process or session keyrings (they\u0027re shared).\n\n(10) Usermode helper.\n\n The usermode helper code now carries a cred struct pointer in its\n subprocess_info struct instead of a new session keyring pointer. This set\n of credentials is derived from init_cred and installed on the new process\n after it has been cloned.\n\n call_usermodehelper_setup() allocates the new credentials and\n call_usermodehelper_freeinfo() discards them if they haven\u0027t been used. A\n special cred function (prepare_usermodeinfo_creds()) is provided\n specifically for call_usermodehelper_setup() to call.\n\n call_usermodehelper_setkeys() adjusts the credentials to sport the\n supplied keyring as the new session keyring.\n\n(11) SELinux.\n\n SELinux has a number of changes, in addition to those to support the LSM\n interface changes mentioned above:\n\n (a) selinux_setprocattr() no longer does its check for whether the\n \t current ptracer can access processes with the new SID inside the lock\n \t that covers getting the ptracer\u0027s SID. Whilst this lock ensures that\n \t the check is done with the ptracer pinned, the result is only valid\n \t until the lock is released, so there\u0027s no point doing it inside the\n \t lock.\n\n(12) is_single_threaded().\n\n This function has been extracted from selinux_setprocattr() and put into\n a file of its own in the lib/ directory as join_session_keyring() now\n wants to use it too.\n\n The code in SELinux just checked to see whether a task shared mm_structs\n with other tasks (CLONE_VM), but that isn\u0027t good enough. We really want\n to know if they\u0027re part of the same thread group (CLONE_THREAD).\n\n(13) nfsd.\n\n The NFS server daemon now has to use the COW credentials to set the\n credentials it is going to use. It really needs to pass the credentials\n down to the functions it calls, but it can\u0027t do that until other patches\n in this series have been applied.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: James Morris \u003cjmorris@namei.org\u003e\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\n" }, { "commit": "8bbf4976b59fc9fc2861e79cab7beb3f6d647640", "tree": "9bd621217cbdfcf94aca5b220de7363254d7fc23", "parents": [ "e9e349b051d98799b743ebf248cc2d986fedf090" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Fri Nov 14 10:39:14 2008 +1100" }, "committer": { "name": "James Morris", "email": "jmorris@namei.org", "time": "Fri Nov 14 10:39:14 2008 +1100" }, "message": "KEYS: Alter use of key instantiation link-to-keyring argument\n\nAlter the use of the key instantiation and negation functions\u0027 link-to-keyring\narguments.

This was\nimplemented by setting sub_info.wait to 0 (implicitly), and doing a\nwait_for_completion().\n\nAs part of the cleanup done in 0ab4dc92278a0f3816e486d6350c6652a72e06c8,\ncall_usermodehelper_pipe() was changed to pass 1 as the value for wait to\ncall_usermodehelper_exec().\n\nThis is equivalent to setting sub_info.wait to 1, which is a change from\nthe previous behaviour. Using 1 instead of 0 causes\n__call_usermodehelper() to start the kernel thread running\nwait_for_helper(), rather than directly calling ____call_usermodehelper().\n\nThe end result is that the calling kernel code blocks until the user mode\nhelper finishes. As the helper is expecting input on stdin, and now no one\nis writing anything, everything locks up (observed in do_coredump).\n\nThe fix is to change the 1 to UMH_WAIT_EXEC (aka 0), indicating that we\nwant to wait for the kernel thread to be started, but not for the helper to\nfinish.\n\nSigned-off-by: Michael Ellerman \u003cmichael@ellerman.id.au\u003e\nAcked-by: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "61df47c8da1b4ba0f243975f11efc8956de0cba6", "tree": "2a8e6d6ae2036bf3cd0a63c8165adaecac6e96bf", "parents": [ "f50cadaa8ffa72ad430e5beabe02eb752f3f72a3" ], "author": { "name": "Randy Dunlap", "email": "randy.dunlap@oracle.com", "time": "Thu Jul 26 10:40:56 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Jul 26 11:33:06 2007 -0700" }, "message": "kernel-doc fix for kmod.c\n\nFix kmod.c:\nWarning(linux-2.6.23-rc1//kernel/kmod.c:364): No description found for parameter \u0027envp\u0027\n\nSigned-off-by: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ccd4b65aef4be2278543fde5b999e55a4d694fd8", "tree": "2753440a79dab444eb3fa01fcaed1c996e1cfe28", "parents": [ "8cdd4936c17bd8085cb0dfacc4a37ccf8d0ada7b" ], "author": { "name": "Rafael J.

The core dump will be\nwritten to the standard input of that program instead of to a file.\n\nThis is useful for having automatic core dump analysis without filling up\ndisks. The program can do some simple analysis and save only a summary of\nthe core dump.\n\nThe core dump proces will run with the privileges and in the name space of\nthe process that caused the core dump.\n\nI also increased the core pattern size to 128 bytes so that longer command\nlines fit.\n\nMost of the changes comes from allowing core dumps without seeks. They are\nfairly straight forward though.\n\nOne small incompatibility is that if someone had a core pattern previously\nthat started with \u0027|\u0027 they will get suddenly new behaviour. I think that\u0027s\nunlikely to be a real problem though.\n\nAdditional background:\n\n\u003e Very nice, do you happen to have a program that can accept this kind of\n\u003e input for crash dumps? I\u0027m guessing that the embedded people will\n\u003e really want this functionality.\n\nI had a cheesy demo/prototype. Basically it wrote the dump to a file again,\nran gdb on it to get a backtrace and wrote the summary to a shared directory.\nThen there was a simple CGI script to generate a \"top 10\" crashes HTML\nlisting.\n\nUnfortunately this still had the disadvantage to needing full disk space for a\ndump except for deleting it afterwards (in fact it was worse because over the\npipe holes didn\u0027t work so if you have a holey address map it would require\nmore space).\n\nFortunately gdb seems to be happy to handle /proc/pid/fd/xxx input pipes as\ncores (at least it worked with zsh\u0027s \u003d(cat core) syntax), so it would be\nlikely possible to do it without temporary space with a simple wrapper that\ncalls it in the right way. I ran out of time before doing that though.\n\nThe demo prototype scripts weren\u0027t very good. If there is really interest I\ncan dig them out (they are currently on a laptop disk on the desk with the\nlaptop itself being in service), but I would recommend to rewrite them for any\nserious application of this and fix the disk space problem.\n\nAlso to be really useful it should probably find a way to automatically fetch\nthe debuginfos (I cheated and just installed them in advance). If nobody else\ndoes it I can probably do the rewrite myself again at some point.\n\nMy hope at some point was that desktops would support it in their builtin\ncrash reporters, but at least the KDE people I talked too seemed to be happy\nwith their user space only solution.\n\nAlan sayeth:\n\n I don\u0027t believe that piping as such as neccessarily the right model, but\n the ability to intercept and processes core dumps from user space is asked\n for by many enterprise users as well.
