We are missing building windfarm_max6690_sensor.o when building CONFIG_WINDFARM_RM31. Usually all the windfarm drivers are built and thus this isn't a problem but some more "tailored" setups (Gentoo ?) building only that driver are not working because the require sensor module is missing.

In a recent patch: commit c13f20ac Author: Michael Neuling <mikey@neuling.org> powerpc/signals: Mark VSX not saved with small contexts We fixed an issue but an improved solution was later discussed after the patch was merged. Firstly, this patch doesn't handle the 64bit signals case, which could also hit this issue (but has never been reported). Secondly, the original patch isn't clear what MSR VSX should be set to. The new approach below always clears the MSR VSX bit (to indicate no VSX is in the context) and sets it only in the specific case where VSX is available (ie. when VSX has been used and the signal context passed has space to provide the state). This reverts the original patch and replaces it with the improved solution. It also adds a 64 bit version. Signed-off-by:

When CONFIG_SPARSEMEM_VMEMMAP option is used in kernel, makedumpfile fails to filter vmcore dump as it fails to do vmemmap translations. So far dump filtering on ppc64 never had to deal with vmemmap addresses seperately as vmemmap regions where mapped in zone normal. But with the inclusion of CONFIG_SPARSEMEM_VMEMMAP config option in kernel, this vmemmap address translation support becomes necessary for dump filtering. For vmemmap adress translation, few kernel symbols are needed by dump filtering tool. This patch adds those symbols to vmcoreinfo, which a dump filtering tool can use for filtering the kernel dump. Tested this changes successfully with makedumpfile tool that supports vmemmap to physical address translation outside zone normal.

Currently if I cross build TAGS or cscope from x86 I get this: % make ARCH=powerpc TAGS gcc-4.8.real: error: unrecognized command line option ‘-mbig-endian’ GEN TAGS % I'm not setting CROSS_COMPILE= as logically I shouldn't need to and I haven't needed to in the past when building TAGS or cscope. Also, the above completess correct as the error is not fatal to the build. This was caused by: commit d72b0801 Author: Ian Munsie <imunsie@au1.ibm.com> powerpc: Add ability to build little endian kernels The below fixes this by testing for the -mbig-endian option before adding it. I've not done the same thing in the little endian case as if -mlittle-endian doesn't exist, we probably want to fail quickly as you probably have an old big endian compiler. Signed-off-by:

And in flush_hugetlb_page(), don't check whether vma is NULL after we've already dereferenced it. This was found by Dan using static analysis as described here: https://lists.ozlabs.org/pipermail/linuxppc-dev/2013-November/113161.html We currently get away with this because the callers that currently pass NULL for vma seem to be 32-bit-only (e.g. highmem, and CONFIG_DEBUG_PGALLOC in pgtable_32.c) Hugetlb is currently 64-bit only, so we never saw a NULL vma here.

If CONFIG_ALTIVEC is enabled for CoreNet64, and if we also select CONFIG_E{5,6}500_CPU this may introduce -mcpu=e500mc64 into $CFLAGS. But Altivec option not allowed with e500mc64, then some compiling errors occur like this: CC arch/powerpc/lib/xor_vmx.o arch/powerpc/lib/xor_vmx.c:1:0: error: AltiVec not supported in this target make[1]: *** [arch/powerpc/lib/xor_vmx.o] Error 1 make: *** [arch/powerpc/lib] Error 2 So we should restrict e500mc64 in altivec scenario.

Pull security subsystem updates from James Morris: "In this patchset, we finally get an SELinux update, with Paul Moore taking over as maintainer of that code. Also a significant update for the Keys subsystem, as well as maintenance updates to Smack, IMA, TPM, and Apparmor" and since I wanted to know more about the updates to key handling, here's the explanation from David Howells on that: "Okay. There are a number of separate bits. I'll go over the big bits and the odd important other bit, most of the smaller bits are just fixes and cleanups. If you want the small bits accounting for, I can do that too. (1) Keyring capacity expansion. KEYS: Consolidate the concept of an 'index key' for key access KEYS: Introduce a search context structure KEYS: Search for auth-key by name rather than target key ID Add a generic associative array implementation. KEYS: Expand the capacity of a keyring Several of the patches are providing an expansion of the capacity of a keyring. Currently, the maximum size of a keyring payload is one page. Subtract a small header and then divide up into pointers, that only gives you ~500 pointers on an x86_64 box. However, since the NFS idmapper uses a keyring to store ID mapping data, that has proven to be insufficient to the cause. Whatever data structure I use to handle the keyring payload, it can only store pointers to keys, not the keys themselves because several keyrings may point to a single key. This precludes inserting, say, and rb_node struct into the key struct for this purpose. I could make an rbtree of records such that each record has an rb_node and a key pointer, but that would use four words of space per key stored in the keyring. It would, however, be able to use much existing code. I selected instead a non-rebalancing radix-tree type approach as that could have a better space-used/key-pointer ratio. I could have used the radix tree implementation that we already have and insert keys into it by their serial numbers, but that means any sort of search must iterate over the whole radix tree. Further, its nodes are a bit on the capacious side for what I want - especially given that key serial numbers are randomly allocated, thus leaving a lot of empty space in the tree. So what I have is an associative array that internally is a radix-tree with 16 pointers per node where the index key is constructed from the key type pointer and the key description. This means that an exact lookup by type+description is very fast as this tells us how to navigate directly to the target key. I made the data structure general in lib/assoc_array.c as far as it is concerned, its index key is just a sequence of bits that leads to a pointer. It's possible that someone else will be able to make use of it also. FS-Cache might, for example. (2) Mark keys as 'trusted' and keyrings as 'trusted only'. KEYS: verify a certificate is signed by a 'trusted' key KEYS: Make the system 'trusted' keyring viewable by userspace KEYS: Add a 'trusted' flag and a 'trusted only' flag KEYS: Separate the kernel signature checking keyring from module signing These patches allow keys carrying asymmetric public keys to be marked as being 'trusted' and allow keyrings to be marked as only permitting the addition or linkage of trusted keys. Keys loaded from hardware during kernel boot or compiled into the kernel during build are marked as being trusted automatically. New keys can be loaded at runtime with add_key(). They are checked against the system keyring contents and if their signatures can be validated with keys that are already marked trusted, then they are marked trusted also and can thus be added into the master keyring. Patches from Mimi Zohar make this usable with the IMA keyrings also. (3) Remove the date checks on the key used to validate a module signature. X.509: Remove certificate date checks It's not reasonable to reject a signature just because the key that it was generated with is no longer valid datewise - especially if the kernel hasn't yet managed to set the system clock when the first module is loaded - so just remove those checks. (4) Make it simpler to deal with additional X.509 being loaded into the kernel. KEYS: Load *.x509 files into kernel keyring KEYS: Have make canonicalise the paths of the X.509 certs better to deduplicate The builder of the kernel now just places files with the extension ".x509" into the kernel source or build trees and they're concatenated by the kernel build and stuffed into the appropriate section. (5) Add support for userspace kerberos to use keyrings. KEYS: Add per-user_namespace registers for persistent per-UID kerberos caches KEYS: Implement a big key type that can save to tmpfs Fedora went to, by default, storing kerberos tickets and tokens in tmpfs. We looked at storing it in keyrings instead as that confers certain advantages such as tickets being automatically deleted after a certain amount of time and the ability for the kernel to get at these tokens more easily. To make this work, two things were needed: (a) A way for the tickets to persist beyond the lifetime of all a user's sessions so that cron-driven processes can still use them. The problem is that a user's session keyrings are deleted when the session that spawned them logs out and the user's user keyring is deleted when the UID is deleted (typically when the last log out happens), so neither of these places is suitable. I've added a system keyring into which a 'persistent' keyring is created for each UID on request. Each time a user requests their persistent keyring, the expiry time on it is set anew. If the user doesn't ask for it for, say, three days, the keyring is automatically expired and garbage collected using the existing gc. All the kerberos tokens it held are then also gc'd. (b) A key type that can hold really big tickets (up to 1MB in size). The problem is that Active Directory can return huge tickets with lots of auxiliary data attached. We don't, however, want to eat up huge tracts of unswappable kernel space for this, so if the ticket is greater than a certain size, we create a swappable shmem file and dump the contents in there and just live with the fact we then have an inode and a dentry overhead. If the ticket is smaller than that, we slap it in a kmalloc()'d buffer" * 'for-linus2' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (121 commits) KEYS: Fix keyring content gc scanner KEYS: Fix error handling in big_key instantiation KEYS: Fix UID check in keyctl_get_persistent() KEYS: The RSA public key algorithm needs to select MPILIB ima: define '_ima' as a builtin 'trusted' keyring ima: extend the measurement list to include the file signature kernel/system_certificate.S: use real contents instead of macro GLOBAL() KEYS: fix error return code in big_key_instantiate() KEYS: Fix keyring quota misaccounting on key replacement and unlink KEYS: Fix a race between negating a key and reading the error set KEYS: Make BIG_KEYS boolean apparmor: remove the "task" arg from may_change_ptraced_domain() apparmor: remove parent task info from audit logging apparmor: remove tsk field from the apparmor_audit_struct apparmor: fix capability to not use the current task, during reporting Smack: Ptrace access check mode ima: provide hash algo info in the xattr ima: enable support for larger default filedata hash algorithms ima: define kernel parameter 'ima_template=' to change configured default ima: add Kconfig default measurement list template ...

I don't know what went wrong, mis-merge or something, but ->pmd_huge_pte placed in wrong union within struct page. In original patch[1] it's placed to union with ->lru and ->slab, but in commit e009bb30 ("mm: implement split page table lock for PMD level") it's in union with ->index and ->freelist. That union seems also unused for pages with table tables and safe to re-use, but it's not what I've tested. Let's move it to original place. It fixes indentation at least. :) [1] https://lkml.org/lkml/2013/10/7/288Signed-off-by:

There are two code paths how page with pmd page table can be freed: pmd_free() and pmd_free_tlb(). I've missed the second one and didn't add page table destructor call there. It leads to leak of page->ptl for pmd page tables, if dynamically allocated page->ptl is in use. The patch adds the missed destructor and modifies documentation accordingly. Signed-off-by:

Commit 2caacaa8 ("ipc,shm: shorten critical region for shmctl") restructured the ipc shm to shorten critical region, but introduced a path where the return value could be -EPERM, even if the operation actually was performed. Before the commit, the err return value was reset by the return value from security_shm_shmctl() after the if (!ns_capable(...)) statement. Now, we still exit the if statement with err set to -EPERM, and in the case of SHM_UNLOCK, it is not reset at all, and used as the return value from shmctl. To fix this, we only set err when errors occur, leaving the fallthrough case alone. Signed-off-by:

Use ARRAY_SIZE instead of sizeof to get proper max for label length. Since this is just a read out of bounds it's not that bad, but the problem becomes user-visible eg if one tries to use DEBUG_PAGEALLOC and DEBUG_RODATA, at least with some enhancements from Hiroshi. Of course the destination array can contain garbage when we read beyond the end of source array so that would be another user-visible problem. Signed-off-by:
