* [PATCH] splice: fix page LRU accountingJens Axboe2006-05-021-3/+2
| | | | | | | | | | | | Currently we rely on the PIPE_BUF_FLAG_LRU flag being set correctly to know whether we need to fiddle with page LRU state after stealing it, however for some origins we just don't know if the page is on the LRU list or not. So remove PIPE_BUF_FLAG_LRU and do this check/add manually in pipe_to_file() instead. Signed-off-by: Jens Axboe <axboe@suse.de>

| * [PATCH] Rework of IPC auditingSteve Grubb2006-05-011-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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] support for context based audit filteringDarrel Goeddel2006-05-012-0/+117
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | [NETFILTER] x_tables: fix compat related crash on non-x86Patrick McHardy2006-05-011-0/+8

On 32 bit architectures where iptables aligns to 8 byte it will also have 4 byte padding at the end because it is only 36 bytes large. The compat_ipt_standard_fn in the kernel adjusts the offsets by sizeof(struct ipt_standard_target) - sizeof(struct compat_ipt_standard_target), which will always result in 4, even if the structure from userspace was already padded to a multiple of 8. On x86 this works out by accident because userspace only aligns to 4, on all other architectures this is broken and causes incorrect adjustments to the size and following offsets.

This patch enables atomic copying of pipe pages, by pre-faulting data and using kmap_atomic() instead. lmbench bw_pipe and lat_pipe measurements agree this is a Good Thing.

| * | [PATCH] pipe: introduce ->pin() buffer operationJens Axboe2006-05-011-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ->map() function is really expensive on highmem machines right now, since it has to use the slower kmap() instead of kmap_atomic(). Splice rarely needs to access the virtual address of a page, so it's a waste of time doing it. Introduce ->pin() to take over the responsibility of making sure the page data is valid. ->map() is then reduced to just kmap(). That way we can also share a most of the pipe buffer ops between pipe.c and splice.c Signed-off-by: Jens Axboe <axboe@suse.de>

And as a cleanup on that: - Make the bottom fall-through logic a little less convoluted. Also make the steal path hold an extra reference to the page, so we don't have to differentiate between stolen and non-stolen at the end. Signed-off-by: Jens Axboe <axboe@suse.de>

Even though the IRQ is disabled it will be latched and delivered when after enable_irq. Thus in the IRQ handler we must avoid starting a new measurement cycle when such an "unwanted" IRQ happens. Add a get_pendown_state platform function, which will probably determine this by reading the current GPIO level of the pen IRQ pin. Move the IRQ reenabling from the SPI RX function to the timer. After the last power down message the pen IRQ pin is still active for a while and get_pendown_state would report incorrectly a pen down state. When suspending we should check the ts->pending flag instead of ts->pendown, since the timer can be pending regardless of ts->pendown. Also if ts->pending is set we can be sure that the timer is running, so no need to rearm it. Similarly if ts->pending is not set we can be sure that the IRQ is enabled (and the timer is not).

| * | | | [PATCH] powerpc: Use check_legacy_ioport() on ppc32 too.David Woodhouse2006-04-281-3/+3

I'd seen it happen on my dual G4 with serial ports until we fixed those to use OF, but now other users are reporting it with i8042. This expands the use of check_legacy_ioport() to avoid that situation even on 32-bit kernels. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * | | | [PATCH] powerpc: Fix pagetable bloat for hugepagesDavid Gibson2006-04-282-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * | | [IA64] enable dumps to capture second page of kernel stackCliff Wickman2006-04-271-1/+1

This is particularly troublesome for dump analysis, as the stack traceback cannot be done. (A similar convention is probably needed throughout the kernel to make kernel multi-page allocations detectable for dumping) Multi-page kernel allocations are represented by the single page structure associated with the first page of the allocation. The page structures associated with the other pages are unintialized. If the dumper is selecting only kernel pages it has no way to identify any but the first page of the allocation. The fix is to make the task/stack allocation a compound page. Signed-off-by: Cliff Wickman <cpw@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

Zone reclaim is important for system that have higher latencies but not for systems that have multiple nodes on one motherboard and therefore low latencies. We found that on motherboard latencies are typically 1 to 1.4 of local memory access speed whereas multinode systems which benefit from zone reclaim have usually more than 1.5 times the latency of a local access. Set the reclaim distance for IA64 to 1.5 times. Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
