This means that\n all the creds can be calculated in advance and then applied at the point\n of no return with no possibility of failure.\n\n I would like to replace bprm-\u003ecap_effective with:\n\n\tcap_isclear(bprm-\u003ecap_effective)\n\n but this seems impossible due to special behaviour for processes of pid 1\n (they always retain their parent\u0027s capability masks where normally they\u0027d\n be changed - see cap_bprm_set_creds()).\n\n The following sequence of events now happens:\n\n (a) At the start of do_execve, the current task\u0027s cred_exec_mutex is\n \t locked to prevent PTRACE_ATTACH from obsoleting the calculation of\n \t creds that we make.\n\n (a) prepare_exec_creds() is then called to make a copy of the current\n \t task\u0027s credentials and prepare it. This copy is then assigned to\n \t bprm-\u003ecred.\n\n \t This renders security_bprm_alloc() and security_bprm_free()\n \t unnecessary, and so they\u0027ve been removed.\n\n (b) The determination of unsafe execution is now performed immediately\n \t after (a) rather than later on in the code. The result is stored in\n \t bprm-\u003eunsafe for future reference.\n\n (c) prepare_binprm() is called, possibly multiple times.\n\n \t (i) This applies the result of set[ug]id binaries to the new creds\n \t attached to bprm-\u003ecred. Personality bit clearance is recorded,\n \t but now deferred on the basis that the exec procedure may yet\n \t fail.\n\n (ii) This then calls the new security_bprm_set_creds(). This should\n\t calculate the new LSM and capability credentials into *bprm-\u003ecred.\n\n\t This folds together security_bprm_set() and parts of\n\t security_bprm_apply_creds() (these two have been removed).\n\t Anything that might fail must be done at this point.\n\n (iii) bprm-\u003ecred_prepared is set to 1.\n\n\t bprm-\u003ecred_prepared is 0 on the first pass of the security\n\t calculations, and 1 on all subsequent passes. This allows SELinux\n\t in (ii) to base its calculations only on the initial script and\n\t not on the interpreter.\n\n (d) flush_old_exec() is called to commit the task to execution. This\n \t performs the following steps with regard to credentials:\n\n\t (i) Clear pdeath_signal and set dumpable on certain circumstances that\n\t may not be covered by commit_creds().\n\n (ii) Clear any bits in current-\u003epersonality that were deferred from\n (c.i).\n\n (e) install_exec_creds() [compute_creds() as was] is called to install the\n \t new credentials. This performs the following steps with regard to\n \t credentials:\n\n (i) Calls security_bprm_committing_creds() to apply any security\n requirements, such as flushing unauthorised files in SELinux, that\n must be done before the credentials are changed.\n\n\t This is made up of bits of security_bprm_apply_creds() and\n\t security_bprm_post_apply_creds(), both of which have been removed.\n\t This function is not allowed to fail; anything that might fail\n\t must have been done in (c.ii).\n\n (ii) Calls commit_creds() to apply the new credentials in a single\n assignment (more or less). Possibly pdeath_signal and dumpable\n should be part of struct creds.\n\n\t (iii) Unlocks the task\u0027s cred_replace_mutex, thus allowing\n\t PTRACE_ATTACH to take place.\n\n (iv) Clears The bprm-\u003ecred pointer as the credentials it was holding\n are now immutable.\n\n (v) Calls security_bprm_committed_creds() to apply any security\n alterations that must be done after the creds have been changed.\n SELinux uses this to flush signals and signal handlers.\n\n (f) If an error occurs before (d.i), bprm_free() will call abort_creds()\n \t to destroy the proposed new credentials and will then unlock\n \t cred_replace_mutex. No changes to the credentials will have been\n \t made.\n\n (2) LSM interface.\n\n A number of functions have been changed, added or removed:\n\n (*) security_bprm_alloc(), -\u003ebprm_alloc_security()\n (*) security_bprm_free(), -\u003ebprm_free_security()\n\n \t Removed in favour of preparing new credentials and modifying those.\n\n (*) security_bprm_apply_creds(), -\u003ebprm_apply_creds()\n (*) security_bprm_post_apply_creds(), -\u003ebprm_post_apply_creds()\n\n \t Removed; split between security_bprm_set_creds(),\n \t security_bprm_committing_creds() and security_bprm_committed_creds().\n\n (*) security_bprm_set(), -\u003ebprm_set_security()\n\n \t Removed; folded into security_bprm_set_creds().\n\n (*) security_bprm_set_creds(), -\u003ebprm_set_creds()\n\n \t New. The new credentials in bprm-\u003ecreds should be checked and set up\n \t as appropriate. bprm-\u003ecred_prepared is 0 on the first call, 1 on the\n \t second and subsequent calls.\n\n (*) security_bprm_committing_creds(), -\u003ebprm_committing_creds()\n (*) security_bprm_committed_creds(), -\u003ebprm_committed_creds()\n\n \t New. Apply the security effects of the new credentials. This\n \t includes closing unauthorised files in SELinux. This function may not\n \t fail. When the former is called, the creds haven\u0027t yet been applied\n \t to the process; when the latter is called, they have.\n\n \t The former may access bprm-\u003ecred, the latter may not.\n\n (3) 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) The bprm_security_struct struct has been removed in favour of using\n \t the credentials-under-construction approach.\n\n (c) flush_unauthorized_files() now takes a cred pointer and passes it on\n \t to inode_has_perm(), file_has_perm() and dentry_open().\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: James Morris \u003cjmorris@namei.org\u003e\nAcked-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\n" }, { "commit": "f4cfb18d7917ecb397b3497e931a2a23175709b7", "tree": "bb891b0f478e2ed7fa9dcefacc0b8342ce1b43d6", "parents": [ "0c6aa2639ea83bfb7f91d72118bad70b3f60012a" ], "author": { "name": "Volodymyr G.

This infrastructure however has some\nshortcommings which can be enhanced. Specifically:\n\n1) The coredump code in the kernel should ignore RLIMIT_CORE limitation\n when core_pattern is a pipe, since file system resources are not being\n consumed in this case, unless the user application wishes to save the core,\n at which point the app is restricted by usual file system limits and\n restrictions.\n\n2) The core_pattern code should be able to parse and pass options to the\n user space helper as an argv array. The real core limit of the uid of the\n crashing proces should also be passable to the user space helper (since it\n is overridden to zero when called).\n\n3) Some miscellaneous bugs need to be cleaned up (specifically the\n recognition of a recursive core dump, should the user mode helper itself\n crash. Also, the core dump code in the kernel should not wait for the user\n mode helper to exit, since the same context is responsible for writing to\n the pipe, and a read of the pipe by the user mode helper will result in a\n deadlock.\n\nThis patch:\n\nRemove the check of RLIMIT_CORE if core_pattern is a pipe. In the event that\ncore_pattern is a pipe, the entire core will be fed to the user mode helper.\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nCc: \u003cmartin.pitt@ubuntu.com\u003e\nCc: \u003cwwoods@redhat.com\u003e\nCc: Jeremy Fitzhardinge \u003cjeremy@goop.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "576bb9ced2d274446639d7fbeee7125e24daf012", "tree": "00a33b5772fe7371d5a47c382d0487e09f01359f", "parents": [ "f9720205d1f847cb59e197e851b5276425363f6b" ], "author": { "name": "Andrew Morton", "email": "akpm@linux-foundation.org", "time": "Wed Oct 03 23:43:57 2007 +0800" }, "committer": { "name": "Bryan Wu", "email": "bryan.wu@analog.com", "time": "Wed Oct 03 23:43:57 2007 +0800" }, "message": "binfmt_flat: checkpatch fixing minimum support for the blackfin relocations\n\nCc: Bernd Schmidt \u003cbernd.schmidt@analog.com\u003e\nCc: David McCullough \u003cdavidm@snapgear.com\u003e\nCc: Greg Ungerer \u003cgerg@snapgear.com\u003e\nCc: Miles Bader \u003cmiles.bader@necel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Bryan Wu \u003cbryan.wu@analog.com\u003e\n" }, { "commit": "f9720205d1f847cb59e197e851b5276425363f6b", "tree": "a90405713cd06f8ead8fff25338a2df5427ac95a", "parents": [ "f778089cb2445dfc6dfd30a7a567925fd8589f1e" ], "author": { "name": "Bernd Schmidt", "email": "bernd.schmidt@analog.com", "time": "Wed Oct 03 23:41:43 2007 +0800" }, "committer": { "name": "Bryan Wu", "email": "bryan.wu@analog.com", "time": "Wed Oct 03 23:41:43 2007 +0800" }, "message": "Binfmt_flat: Add minimum support for the Blackfin relocations\n\nAdd minimum support for the Blackfin relocations, since we don\u0027t have\nenough space in each reloc.
