| * | SHM_UNLOCK: fix Unevictable pages stranded after swapHugh Dickins2012-01-23

The only uses of find_get_pages() on shmem are via pagevec_lookup(), called from invalidate_mapping_pages(), and from shmctl SHM_UNLOCK's scan_mapping_unevictable_pages(). The first is already commented, and not worth worrying about; but the second can leave pages on the Unevictable list after an unusual sequence of swapping and locking. Fix that by using shmem_find_get_pages_and_swap() (then ignoring the swap) instead of pagevec_lookup(). But I don't want to contaminate vmscan.c with shmem internals, nor shmem.c with LRU locking. So move scan_mapping_unevictable_pages() into shmem.c, renaming it shmem_unlock_mapping(); and rename check_move_unevictable_page() to check_move_unevictable_pages(), looping down an array of pages, oftentimes under the same lock. Leave out the "rotate unevictable list" block: that's a leftover from when this was used for /proc/sys/vm/scan_unevictable_pages, whose flawed handling involved looking at pages at tail of LRU. Was there significance to the sequence first ClearPageUnevictable, then test page_evictable, then SetPageUnevictable here? I think not, we're under LRU lock, and have no barriers between those.

| * | kdump: define KEXEC_NOTE_BYTES arch specific for s390xMichael Holzheu2012-01-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kdump only allocates memory for the prstatus ELF note. For s390x, besides of prstatus multiple ELF notes for various different register types are stored. Therefore the currently allocated memory is not sufficient. With this patch the KEXEC_NOTE_BYTES macro can be defined by architecture code and for s390x it is set to the correct size now.

| * keys: add a "logon" key typeJeff Layton2012-01-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For CIFS, we want to be able to store NTLM credentials (aka username and password) in the keyring. We do not, however want to allow users to fetch those keys back out of the keyring since that would be a security risk. Unfortunately, due to the nuances of key permission bits, it's not possible to do this. We need to grant search permissions so the kernel can find these keys, but that also implies permissions to read the payload. Resolve this by adding a new key_type. This key type is essentially the same as key_type_user, but does not define a .read op. This prevents the payload from ever being visible from userspace. This key type also vets the description to ensure that it's "qualified" by checking to ensure that it has a ':' in it that is preceded by other characters.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Historically, pSCSI devices have been the ones that required target-core to enforce a per se_device->depth_left.

It sets the default cmd_kref count value to '2' within target_get_sess_cmd() setup, and currently assumes TFO->check_stop_free() usage.

Also extensions for vendor specific error injections. Tested-by: Chen Gong <gong.chen@linux.intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

The acpi_os_map_generic_address() and acpi_os_unmap_generic_address() declarations may more properly belong in include/acpi/acpiosxf.h next to acpi_os_read_memory() but I believe that would require the ACPI CA making them an official part of the ACPI CA - OS interface.

That is, instructions in APEI ERST/EINJ table will read/write ACPI NVS region. The original resource conflict checking in APEI code will check memory/ioport accessed by APEI via general resource management mechanism. But ACPI NVS region is marked as busy already, so that the false resource conflict will prevent APEI ERST/EINJ to work. To fix this, this patch record ACPI NVS regions, so that we can avoid request resources for memory region inside it.
