A mapping is created between kernel-private\nclass and permission indices used outside the security server and the\npolicy values used within the security server.\n\nThe mappings are only applied upon kernel-internal computations;\nsimilar mappings for the private indices of userspace object managers\nis handled on a per-object manager basis by the userspace AVC. The\ninterfaces for compute_av and transition_sid are split for kernel\nvs. userspace; the userspace functions are distinguished by a _user\nsuffix.\n\nThe kernel-private class indices are no longer tied to the policy\nvalues and thus do not need to skip indices for userspace classes;\nthus the kernel class index values are compressed. The flask.h\ndefinitions were regenerated by deleting the userspace classes from\nrefpolicy\u0027s definitions and then regenerating the headers. Going\nforward, we can just maintain the flask.h, av_permissions.h, and\nclassmap.h definitions separately from policy as they are no longer\ntied to the policy values. The next patch introduces a utility to\nautomate generation of flask.h and av_permissions.h from the\nclassmap.h definitions.\n\nThe older kernel class and permission string tables are removed and\nreplaced by a single security class mapping table that is walked at\npolicy load to generate the mapping. The old kernel class validation\nlogic is completely replaced by the mapping logic.\n\nThe handle unknown logic is reworked. reject_unknown\u003d1 is handled\nwhen the mappings are computed at policy load time, similar to the old\nhandling by the class validation logic. allow_unknown\u003d1 is handled\nwhen computing and mapping decisions - if the permission was not able\nto be mapped (i.e. undefined, mapped to zero), then it is\nautomatically added to the allowed vector. If the class was not able\nto be mapped (i.e. undefined, mapped to zero), then all permissions\nare allowed for it if allow_unknown\u003d1.\n\navc_audit leverages the new security class mapping table to lookup the\nclass and permission names from the kernel-private indices.\n\nThe mdp program is updated to use the new table when generating the\nclass definitions and allow rules for a minimal boot policy for the\nkernel. It should be noted that this policy will not include any\nuserspace classes, nor will its policy index values for the kernel\nclasses correspond with the ones in refpolicy (they will instead match\nthe kernel-private indices).\n\nSigned-off-by: Stephen Smalley \u003csds@tycho.nsa.gov\u003e\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\n" }, { "commit": "af8ff04917169805b151280155bf772d3ca9bec0", "tree": "1a1ec17d0926b4bbe9f8b243231582dde02ef1f5", "parents": [ "1669b049db50fc7f1d4e694fb115a0f408c63fce" ], "author": { "name": "Eric Paris", "email": "eparis@redhat.com", "time": "Sun Sep 20 21:23:01 2009 -0400" }, "committer": { "name": "James Morris", "email": "jmorris@namei.org", "time": "Wed Sep 30 19:17:06 2009 +1000" }, "message": "SELinux: reset the security_ops before flushing the avc cache\n\nThis patch resets the security_ops to the secondary_ops before it flushes\nthe avc.

As was suggested by Eric Biederman the struct iattr in the\nsysfs_dirent structure has been replaced by a structure which contains the\niattr, secdata and secdata length to allow the changes to persist in the event\nthat the inode representing the sysfs_dirent is evicted. Because sysfs only\nstores this information when a change is made all the optional data is moved\ninto one dynamically allocated field.\n\nThis patch addresses an issue where SELinux was denying virtd access to the PCI\nconfiguration entries in sysfs. The lack of setxattr handlers for sysfs\nrequired that a single label be assigned to all entries in sysfs.

The inode_getsecctx hook is used to get\nall relevant information from an LSM about an inode.

These hooks are\nfor use in the labeled NFS code and addresses concerns of how to set security\non an inode in a multi-xattr LSM.

Updates the\nin core security context managed by the security module and invokes the\nfs code as needed (via __vfs_setxattr_noperm) to update any backing\nxattrs that represent the context. Example usage: NFS server invokes\nthis hook to change the security context in its incore inode and on the\nbacking file system to a value provided by the client on a SETATTR\noperation.\n\ninode_notifysecctx: Notify the security module of what the security\ncontext of an inode should be. Initializes the incore security context\nmanaged by the security module for this inode. Example usage: NFS\nclient invokes this hook to initialize the security context in its\nincore inode to the value provided by the server for the file when the\nserver returned the file\u0027s attributes to the client.\n\nSigned-off-by: David P.

This\nreplaces the parent\u0027s session keyring. Because the COW credential code does\nnot permit one process to change another process\u0027s credentials directly, the\nchange is deferred until userspace next starts executing again. Normally this\nwill be after a wait*() syscall.\n\nTo support this, three new security hooks have been provided:\ncred_alloc_blank() to allocate unset security creds, cred_transfer() to fill in\nthe blank security creds and key_session_to_parent() - which asks the LSM if\nthe process may replace its parent\u0027s session keyring.\n\nThe replacement may only happen if the process has the same ownership details\nas its parent, and the process has LINK permission on the session keyring, and\nthe session keyring is owned by the process, and the LSM permits it.\n\nNote that this requires alteration to each architecture\u0027s notify_resume path.\nThis has been done for all arches barring blackfin, m68k* and xtensa, all of\nwhich need assembly alteration to support TIF_NOTIFY_RESUME. This allows the\nreplacement to be performed at the point the parent process resumes userspace\nexecution.\n\nThis allows the userspace AFS pioctl emulation to fully emulate newpag() and\nthe VIOCSETTOK and VIOCSETTOK2 pioctls, all of which require the ability to\nalter the parent process\u0027s PAG membership.

The problem is that network sockets\ncreated as the result of an incoming TCP connection were not on-the-wire\nlabeled based on the security attributes of the parent socket but rather based\non the wire label of the remote peer. The issue had to do with how IP options\nwere managed as part of the network stack and where the LSM hooks were in\nrelation to the code which set the IP options on these newly created child\nsockets. While NetLabel/SELinux did correctly set the socket\u0027s on-the-wire\nlabel it was promptly cleared by the network stack and reset based on the IP\noptions of the remote peer.\n\nThis patch, in conjunction with a prior patch that adjusted the LSM hook\nlocations, works to set the correct on-the-wire label format for new incoming\nconnections through the security_inet_conn_request() hook. Besides the\ncorrect behavior there are many advantages to this change, the most significant\nis that all of the NetLabel socket labeling code in SELinux now lives in hooks\nwhich can return error codes to the core stack which allows us to finally get\nride of the selinux_netlbl_inode_permission() logic which greatly simplfies\nthe NetLabel/SELinux glue code.

However, sys_faccessat() makes use of this\nfacility to override the credentials of the calling process to make its test,\nwithout affecting the creds as seen from other processes.\n\nOne of the things sys_faccessat() does is to make an adjustment to the\neffective capabilities mask, which cap_capable(), as it stands, then ignores.\n\nThe affected capability check is in generic_permission():\n\n\tif (!(mask \u0026 MAY_EXEC) || execute_ok(inode))\n\t\tif (capable(CAP_DAC_OVERRIDE))\n\t\t\treturn 0;\n\nThis change passes the set of credentials to be tested down into the commoncap\nand SELinux code.

However, sys_faccessat() makes use of this\nfacility to override the credentials of the calling process to make its test,\nwithout affecting the creds as seen from other processes.\n\nOne of the things sys_faccessat() does is to make an adjustment to the\neffective capabilities mask, which cap_capable(), as it stands, then ignores.\n\nThe affected capability check is in generic_permission():\n\n\tif (!(mask \u0026 MAY_EXEC) || execute_ok(inode))\n\t\tif (capable(CAP_DAC_OVERRIDE))\n\t\t\treturn 0;\n\nThis change splits capable() from has_capability() down into the commoncap and\nSELinux code. The capable() security op now only deals with the current\nprocess, and uses the current process\u0027s subjective creds. A new security op -\ntask_capable() - is introduced that can check any task\u0027s objective creds.\n\nstrictly the capable() security op is superfluous with the presence of the\ntask_capable() op, however it should be faster to call the capable() op since\ntwo fewer arguments need be passed down through the various layers.\n\nThis can be tested by compiling the following program from the XFS testsuite:\n\n/*\n * t_access_root.c - trivial test program to show permission bug.\n *\n * Written by Michael Kerrisk - copyright ownership not pursued.\n * Sourced from: http://linux.derkeiler.com/Mailing-Lists/Kernel/2003-10/6030.html\n */\n#include \u003climits.h\u003e\n#include \u003cunistd.h\u003e\n#include \u003cstdio.h\u003e\n#include \u003cstdlib.h\u003e\n#include \u003cfcntl.h\u003e\n#include \u003csys/stat.h\u003e\n\n#define UID 500\n#define GID 100\n#define PERM 0\n#define TESTPATH \"/tmp/t_access\"\n\nstatic void\nerrExit(char *msg)\n{\n perror(msg);\n exit(EXIT_FAILURE);\n} /* errExit */\n\nstatic void\naccessTest(char *file, int mask, char *mstr)\n{\n printf(\"access(%s, %s) returns %d\\n\", file, mstr, access(file, mask));\n} /* accessTest */\n\nint\nmain(int argc, char *argv[])\n{\n int fd, perm, uid, gid;\n char *testpath;\n char cmd[PATH_MAX + 20];\n\n testpath \u003d (argc \u003e 1) ? argv[1] : TESTPATH;\n perm \u003d (argc \u003e 2) ? strtoul(argv[2], NULL, 8) : PERM;\n uid \u003d (argc \u003e 3) ? atoi(argv[3]) : UID;\n gid \u003d (argc \u003e 4) ? atoi(argv[4]) : GID;\n\n unlink(testpath);\n\n fd \u003d open(testpath, O_RDWR | O_CREAT, 0);\n if (fd \u003d\u003d -1) errExit(\"open\");\n\n if (fchown(fd, uid, gid) \u003d\u003d -1) errExit(\"fchown\");\n if (fchmod(fd, perm) \u003d\u003d -1) errExit(\"fchmod\");\n close(fd);\n\n snprintf(cmd, sizeof(cmd), \"ls -l %s\", testpath);\n system(cmd);\n\n if (seteuid(uid) \u003d\u003d -1) errExit(\"seteuid\");\n\n accessTest(testpath, 0, \"0\");\n accessTest(testpath, R_OK, \"R_OK\");\n accessTest(testpath, W_OK, \"W_OK\");\n accessTest(testpath, X_OK, \"X_OK\");\n accessTest(testpath, R_OK | W_OK, \"R_OK | W_OK\");\n accessTest(testpath, R_OK | X_OK, \"R_OK | X_OK\");\n accessTest(testpath, W_OK | X_OK, \"W_OK | X_OK\");\n accessTest(testpath, R_OK | W_OK | X_OK, \"R_OK | W_OK | X_OK\");\n\n exit(EXIT_SUCCESS);\n} /* main */\n\nThis can be run against an Ext3 filesystem as well as against an XFS\nfilesystem.
