* [PATCH] Rework of IPC auditingSteve Grubb2006-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) The audit_ipc_perms() function has been split into two different functions: - audit_ipc_obj() - audit_ipc_set_perm() There's a key shift here... The audit_ipc_obj() collects the uid, gid, mode, and SElinux context label of the current ipc object. This audit_ipc_obj() hook is now found in several places. Most notably, it is hooked in ipcperms(), which is called in various places around the ipc code permforming a MAC check. Additionally there are several places where *checkid() is used to validate that an operation is being performed on a valid object while not necessarily having a nearby ipcperms() call. In these locations, audit_ipc_obj() is called to ensure that the information is captured by the audit system. The audit_set_new_perm() function is called any time the permissions on the ipc object changes. In this case, the NEW permissions are recorded (and note that an audit_ipc_obj() call exists just a few lines before each instance). 2) Support for an AUDIT_IPC_SET_PERM audit message type. This allows for separate auxiliary audit records for normal operations on an IPC object and permissions changes. Note that the same struct audit_aux_data_ipcctl is used and populated, however there are separate audit_log_format statements based on the type of the message. Finally, the AUDIT_IPC block of code in audit_free_aux() was extended to handle aux messages of this new type. No more mem leaks I hope ;-) Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* [PATCH] More user space subject labelsSteve Grubb2006-05-01

* [PATCH] change lspp ipc auditingSteve Grubb2006-05-01

* [PATCH] audit inode patchSteve Grubb2006-05-01
| | | | | | | | | | Previously, we were gathering the context instead of the sid. Now in this patch, we gather just the sid and convert to context only if an audit event is being output. This patch brings the performance hit from 146% down to 23% Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* [PATCH] support for context based audit filtering, part 2Darrel Goeddel2006-05-01
| | | | | | | | | | | This patch provides the ability to filter audit messages based on the elements of the process' SELinux context (user, role, type, mls sensitivity, and mls clearance). It uses the new interfaces from selinux to opaquely store information related to the selinux context and to filter based on that information. It also uses the callback mechanism provided by selinux to refresh the information when a new policy is loaded. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* [PATCH] support for context based audit filteringDarrel Goeddel2006-05-01
| | | | | | | | | | | | | The following patch provides selinux interfaces that will allow the audit system to perform filtering based on the process context (user, role, type, sensitivity, and clearance). These interfaces will allow the selinux module to perform efficient matches based on lower level selinux constructs, rather than relying on context retrievals and string comparisons within the audit module. It also allows for dominance checks on the mls portion of the contexts that are impossible with only string comparisons.

| | | | | | | | | | | | | | | | | | | | | | | | | | Some people report that we die on some Macs when we are expecting to catch machine checks after poking at some random I/O address.

| * [PATCH] powerpc64: Fix loading of modules without a .toc sectionAlan Modra2006-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally, ppc64 module .ko files contain a table-of-contents (.toc) section, but if the module doesn't reference any static or external data or external procedures, it is possible for gcc/binutils to generate a .ko that doesn't have a .toc. Currently the module loader refuses to load such a module, since it needs the address of the .toc section to use in relocations. This patch fixes the problem by using the address of the .stubs section instead, which is an acceptable substitute in this situation. Signed-off-by: Paul Mackerras <paulus@samba.org>

| * [PATCH] powerpc: Fix pagetable bloat for hugepagesDavid Gibson2006-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present, ARCH=powerpc kernels can waste considerable space in pagetables when making large hugepage mappings. Hugepage PTEs go in PMD pages, but each PMD page maps 256M and so contains only 16 hugepage PTEs (128 bytes of data), but takes up a 1024 byte allocation. With CONFIG_PPC_64K_PAGES enabled (64k base page size), the situation is worse. Now hugepage PTEs are at the PTE page level (also mapping 256M), so we store 16 hugepage PTEs in a 64k allocation. The PowerPC MMU already means that any 256M region is either all hugepage, or all normal pages. Thus, with some care, we can use a different allocation for the hugepage PTE tables and only allocate the 128 bytes necessary. Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When trap happens in user space, kprobe_exceptions_notify() funtion will skip it.

* | [PATCH] Mark VMSPLIT EMBEDDEDAndi Kleen2006-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Running abnormal VM splits causes weird problems - people can set non-standard splits by accident, then lots of time gets wasted diagnosing it - see the long "[stable] 2.6.16.6 breaks java... sort of" email thread. So we need to make this option harder to set. Use CONFIG_EMBEDDED for this. CONFIG_EMBEDDED isn't really the right thing to use, but there's nothing else obvious and avoiding these problems is more important than Kconfig purity.
