This is\nrequired by various security standards such as DCID 6/3 and PCI to provide\nnon-repudiation of administrator\u0027s actions and to allow a review of past\nactions if the administrator seems to overstep their duties or if the system\nbecomes misconfigured for unknown reasons. These requirements do not make it\nnecessary to audit TTY output as well.\n\nCompared to an user-space keylogger, this approach records TTY input using the\naudit subsystem, correlated with other audit events, and it is completely\ntransparent to the user-space application (e.g. the console ioctls still\nwork).\n\nTTY input auditing works on a higher level than auditing all system calls\nwithin the session, which would produce an overwhelming amount of mostly\nuseless audit events.\n\nAdd an \"audit_tty\" attribute, inherited across fork (). Data read from TTYs\nby process with the attribute is sent to the audit subsystem by the kernel.\nThe audit netlink interface is extended to allow modifying the audit_tty\nattribute, and to allow sending explanatory audit events from user-space (for\nexample, a shell might send an event containing the final command, after the\ninteractive command-line editing and history expansion is performed, which\nmight be difficult to decipher from the TTY input alone).\n\nBecause the \"audit_tty\" attribute is inherited across fork (), it would be set\ne.g. for sshd restarted within an audited session. To prevent this, the\naudit_tty attribute is cleared when a process with no open TTY file\ndescriptors (e.g. after daemon startup) opens a TTY.\n\nSee https://www.redhat.com/archives/linux-audit/2007-June/msg00000.html for a\nmore detailed rationale document for an older version of this patch.\n\n[akpm@linux-foundation.org: build fix]\nSigned-off-by: Miloslav Trmac \u003cmitr@redhat.com\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: Paul Fulghum \u003cpaulkf@microgate.com\u003e\nCc: Casey Schaufler \u003ccasey@schaufler-ca.com\u003e\nCc: Steve Grubb \u003csgrubb@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "8d9107e8c50e1c4ff43c91c8841805833f3ecfb9", "tree": "abc57f38cf659d4031d5a9915a088f2c47b2cc7e", "parents": [ "16cefa8c3863721fd40445a1b34dea18cd16ccfe" ], "author": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Jul 13 16:53:18 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Jul 13 16:53:18 2007 -0700" }, "message": "Revert \"SELinux: use SECINITSID_NETMSG instead of SECINITSID_UNLABELED for NetLabel\"\n\nThis reverts commit 9faf65fb6ee2b4e08325ba2d69e5ccf0c46453d0.\n\nIt bit people like Michal Piotrowski:\n\n \"My system is too secure, I can not login :)\"\n\nbecause it changed how CONFIG_NETLABEL worked, and broke older SElinux\npolicies.\n\nAs a result, quoth James Morris:\n\n \"Can you please revert this patch?\n\n We thought it only affected people running MLS, but it will affect others.\n\n Sorry for the hassle.\"\n\nCc: James Morris \u003cjmorris@namei.org\u003e\nCc: Stephen Smalley \u003csds@tycho.nsa.gov\u003e\nCc: Michal Piotrowski \u003cmichal.k.k.piotrowski@gmail.com\u003e\nCc: Paul Moore \u003cpaul.moore@hp.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d4cf291526a74cc33d33700a35b74395eec812fd", "tree": "321018f7ef60b7cf2df7104f5361901d021edfdb", "parents": [ "9faf65fb6ee2b4e08325ba2d69e5ccf0c46453d0" ], "author": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Sun Jul 01 22:23:53 2007 +0200" }, "committer": { "name": "James Morris", "email": "jmorris@namei.org", "time": "Wed Jul 11 22:52:33 2007 -0400" }, "message": "security: unexport mmap_min_addr\n\nRemove unneeded export.\n\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\n" }, { "commit": "9faf65fb6ee2b4e08325ba2d69e5ccf0c46453d0", "tree": "ee167dc8c575dee062cdaf91d0b60a5997bba0c3", "parents": [ "ed0321895182ffb6ecf210e066d87911b270d587" ], "author": { "name": "Paul Moore", "email": "paul.moore@hp.com", "time": "Fri Jun 29 11:48:16 2007 -0400" }, "committer": { "name": "James Morris", "email": "jmorris@namei.org", "time": "Wed Jul 11 22:52:31 2007 -0400" }, "message": "SELinux: use SECINITSID_NETMSG instead of SECINITSID_UNLABELED for NetLabel\n\nThese changes will make NetLabel behave like labeled IPsec where there is an\naccess check for both labeled and unlabeled packets as well as providing the\nability to restrict domains to receiving only labeled packets when NetLabel\nis in use.

As an added bonus, most of the supporting\ncode becomes simpler.\n\nSigned-off-by: Vadim Lobanov \u003cvlobanov@speakeasy.net\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Dipankar Sarma \u003cdipankar@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "3d5ff529ea222461a5fa3c4df05cbdc5eb56864d", "tree": "28ec8432eb9212bc04e345c2e85addc132f3a34e", "parents": [ "7ac6207b2a6a5b828bc333f2530a3bd48197af3e" ], "author": { "name": "Josef Sipek", "email": "jsipek@fsl.cs.sunysb.edu", "time": "Fri Dec 08 02:37:38 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Fri Dec 08 08:28:49 2006 -0800" }, "message": "[PATCH] struct path: convert selinux\n\nSigned-off-by: Josef Sipek \u003cjsipek@fsl.cs.sunysb.edu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "24ec839c431eb79bb8f6abc00c4e1eb3b8c4d517", "tree": "2ff478b1925159eeac007913c2a8f19d5f5e6010", "parents": [ "562f9c574e0707f9159a729ea41faf53b221cd30" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Fri Dec 08 02:36:04 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Fri Dec 08 08:28:38 2006 -0800" }, "message": "[PATCH] tty: -\u003esignal-\u003etty locking\n\nFix the locking of signal-\u003etty.\n\nUse -\u003esighand-\u003esiglock to protect -\u003esignal-\u003etty; this lock is already used\nby most other members of -\u003esignal/-\u003esighand.

We were not handling that correctly, and in fact\ninverting the return logic and propagating a false \"ok\" back up to\nxfrm_lookup(), which then allowed packets to pass as if they were not\nassociated with an xfrm policy.\n\nThe solution for this is to first ensure that errno values are\ncorrectly propagated all the way back up through the various call chains\nfrom security_xfrm_policy_lookup(), and handled correctly.\n\nThen, flow_cache_lookup() is modified, so that if the policy resolver\nfails (typically a permission denied via the security module), the flow\ncache entry is killed rather than having a null policy assigned (which\nindicates that the packet can pass freely). This also forces any future\nlookups for the same flow to consult the security module (e.g. SELinux)\nfor current security policy (rather than, say, caching the error on the\nflow cache entry).\n\nThis patch: Fix the selinux side of things.\n\nThis makes sure SELinux polmatching of flow contexts to IPSec policy\nrules comes into play only when an explicit context is associated\nwith the IPSec policy rule.\n\nAlso, this no longer defaults the context of a socket policy to\nthe context of the socket since the \"no explicit context\" case\nis now handled properly.\n\nSigned-off-by: Venkat Yekkirala \u003cvyekkirala@TrustedCS.com\u003e\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\n" }, { "commit": "388b24057f90ba109d4bf855006a8809c383eb76", "tree": "44ab16f68b08ac7ed64ba4e4f2be87a6476a5d4c", "parents": [ "ffb733c65000ee701294f7b80c4eca2a5f335637" ], "author": { "name": "paul.moore@hp.com", "email": "paul.moore@hp.com", "time": "Thu Oct 05 18:28:24 2006 -0400" }, "committer": { "name": "David S.
