78dc53c Linus Torvalds 22 November 2013, 03:46:00 UTC Merge branch 'for-linus2' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security 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 ... 22 November 2013, 03:46:00 UTC

In original patch[1] it's placed to union with ->lru and ->slab, but in commit e009bb30c8df ("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.

3a72660 Jesper Nilsson 21 November 2013, 22:32:08 UTC ipc,shm: correct error return value in shmctl (SHM_UNLOCK) Commit 2caacaa82a51 ("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.

27c73ae Andrea Arcangeli 21 November 2013, 22:32:02 UTC mm: hugetlbfs: fix hugetlbfs optimization Commit 7cb2ef56e6a8 ("mm: fix aio performance regression for database caused by THP") can cause dereference of a dangling pointer if split_huge_page runs during PageHuge() if there are updates to the tail_page->private field. Also it is repeating compound_head twice for hugetlbfs and it is running compound_head+compound_trans_head for THP when a single one is needed in both cases. The new code within the PageSlab() check doesn't need to verify that the THP page size is never bigger than the smallest hugetlbfs page size, to avoid memory corruption. A longstanding theoretical race condition was found while fixing the above (see the change right after the skip_unlock label, that is relevant for the compound_lock path too). By re-establishing the _mapcount tail refcounting for all compound pages, this also fixes the below problem: echo 0 >/sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages BUG: Bad page state in process bash pfn:59a01 page:ffffea000139b038 count:0 mapcount:10 mapping: (null) index:0x0 page flags: 0x1c00000000008000(tail) Modules linked in: CPU: 6 PID: 2018 Comm: bash Not tainted 3.12.0+ #25 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 Call Trace: dump_stack+0x55/0x76 bad_page+0xd5/0x130 free_pages_prepare+0x213/0x280 __free_pages+0x36/0x80 update_and_free_page+0xc1/0xd0 free_pool_huge_page+0xc2/0xe0 set_max_huge_pages.part.58+0x14c/0x220 nr_hugepages_store_common.isra.60+0xd0/0xf0 nr_hugepages_store+0x13/0x20 kobj_attr_store+0xf/0x20 sysfs_write_file+0x189/0x1e0 vfs_write+0xc5/0x1f0 SyS_write+0x55/0xb0 system_call_fastpath+0x16/0x1b Signed-off-by: Khalid Aziz <khalid.aziz@oracle.com> Signed-off-by: Andrea Arcangeli <aarcange@redhat.com> Tested-by: Khalid Aziz <khalid.aziz@oracle.com> Cc: Pravin Shelar <pshelar@nicira.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Ben Hutchings <bhutchings@solarflare.com> Cc: Christoph Lameter <cl@linux.com> Cc: Johannes Weiner <jweiner@redhat.com> Cc: Mel Gorman <mgorman@suse.de> Cc: Rik van Riel <riel@redhat.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: Minchan Kim <minchan@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 22 November 2013, 00:42:27 UTC

a399b29 Greg Thelen 21 November 2013, 22:32:00 UTC ipc,shm: fix shm_file deletion races When IPC_RMID races with other shm operations there's potential for use-after-free of the shm object's associated file (shm_file). Here's the race before this patch: TASK 1 TASK 2 ------ ------ shm_rmid() ipc_lock_object() shmctl() shp = shm_obtain_object_check() shm_destroy() shum_unlock() fput(shp->shm_file) ipc_lock_object() shmem_lock(shp->shm_file) <OOPS> The oops is caused because shm_destroy() calls fput() after dropping the ipc_lock. fput() clears the file's f_inode, f_path.dentry, and f_path.mnt, which causes various NULL pointer references in task 2. I reliably see the oops in task 2 if with shmlock, shmu This patch fixes the races by: 1) set shm_file=NULL in shm_destroy() while holding ipc_object_lock(). 2) modify at risk operations to check shm_file while holding ipc_object_lock(). Example workloads, which each trigger oops... Workload 1: while true; do id=$(shmget 1 4096) shm_rmid $id & shmlock $id & wait done The oops stack shows accessing NULL f_inode due to racing fput: _raw_spin_lock shmem_lock SyS_shmctl Workload 2: while true; do id=$(shmget 1 4096) shmat $id 4096 & shm_rmid $id & wait done The oops stack is similar to workload 1 due to NULL f_inode: touch_atime shmem_mmap shm_mmap mmap_region do_mmap_pgoff do_shmat SyS_shmat Workload 3: while true; do id=$(shmget 1 4096) shmlock $id shm_rmid $id & shmunlock $id & wait done The oops stack shows second fput tripping on an NULL f_inode.

30b0a10 Dave Hansen 21 November 2013, 22:31:58 UTC mm: thp: give transparent hugepage code a separate copy_page Right now, the migration code in migrate_page_copy() uses copy_huge_page() for hugetlbfs and thp pages: if (PageHuge(page) || PageTransHuge(page)) copy_huge_page(newpage, page); So, yay for code reuse. But: void copy_huge_page(struct page *dst, struct page *src) { struct hstate *h = page_hstate(src); and a non-hugetlbfs page has no page_hstate(). This works 99% of the time because page_hstate() determines the hstate from the page order alone. Since the page order of a THP page matches the default hugetlbfs page order, it works. But, if you change the default huge page size on the boot command-line (say default_hugepagesz=1G), then we might not even *have* a 2MB hstate so page_hstate() returns null and copy_huge_page() oopses pretty fast since copy_huge_page() dereferences the hstate: void copy_huge_page(struct page *dst, struct page *src) { struct hstate *h = page_hstate(src); if (unlikely(pages_per_huge_page(h) > MAX_ORDER_NR_PAGES)) { ... Mel noticed that the migration code is really the only user of these functions. This moves all the copy code over to migrate.c and makes copy_huge_page() work for THP by checking for it explicitly.

In this window, if a lookup happen, since the original dentry was UNHASHED, so a new dentry will be allocated, and then in configfs_attach_attr(), sd->s_dentry will be updated to the new dentry. Then in configfs_d_iput(), BUG_ON(sd->s_dentry != dentry) will be triggered and system panic. sys_open: sys_close: ... fput dput dentry_kill __d_drop <--- dentry unhashed here, but sd->dentry still point to this dentry. lookup_real configfs_lookup configfs_attach_attr---> update sd->s_dentry to new allocated dentry here. d_kill configfs_d_iput <--- BUG_ON(sd->s_dentry != dentry) triggered here. To fix it, change configfs_d_iput to not update sd->s_dentry if sd->s_count > 2, that means there are another dentry is using the sd beside the one that is going to be put. Use configfs_dirent_lock in configfs_attach_attr to sync with configfs_d_iput.

9d8506c Herbert Xu 21 November 2013, 19:10:04 UTC gso: handle new frag_list of frags GRO packets Recently GRO started generating packets with frag_lists of frags. This was not handled by GSO, thus leading to a crash. Thankfully these packets are of a regular form and are easy to handle. This patch handles them in two ways. For completely non-linear frag_list entries, we simply continue to iterate over the frag_list frags once we exhaust the normal frags. For frag_list entries with linear parts, we call pskb_trim on the first part of the frag_list skb, and then process the rest of the frags in the usual way. This patch also kills a chunk of dead frag_list code that has obviously never ever been run since it ends up generating a bogus GSO-segmented packet with a frag_list entry. Future work is planned to split super big packets into TSO ones.

e40526c Daniel Borkmann 21 November 2013, 15:50:58 UTC packet: fix use after free race in send path when dev is released Salam reported a use after free bug in PF_PACKET that occurs when we're sending out frames on a socket bound device and suddenly the net device is being unregistered. It appears that commit 827d9780 introduced a possible race condition between {t,}packet_snd() and packet_notifier(). In the case of a bound socket, packet_notifier() can drop the last reference to the net_device and {t,}packet_snd() might end up suddenly sending a packet over a freed net_device. To avoid reverting 827d9780 and thus introducing a performance regression compared to the current state of things, we decided to hold a cached RCU protected pointer to the net device and maintain it on write side via bind spin_lock protected register_prot_hook() and __unregister_prot_hook() calls. In {t,}packet_snd() path, we access this pointer under rcu_read_lock through packet_cached_dev_get() that holds reference to the device to prevent it from being freed through packet_notifier() while we're in send path. This is okay to do as dev_put()/dev_hold() are per-cpu counters, so this should not be a performance issue. Also, the code simplifies a bit as we don't need need_rls_dev anymore.

8a3caa6 Heiko Carstens 18 November 2013, 09:35:55 UTC KVM: kvm_clear_guest_page(): fix empty_zero_page usage Using the address of 'empty_zero_page' as source address in order to clear a page is wrong. On some architectures empty_zero_page is only the pointer to the struct page of the empty_zero_page. Therefore the clear page operation would copy the contents of a couple of struct pages instead of clearing a page. For kvm only arm/arm64 are affected by this bug. To fix this use the ZERO_PAGE macro instead which will return the struct page address of the empty_zero_page on all architectures.

f3d3342 Hannes Frederic Sowa 21 November 2013, 02:14:22 UTC net: rework recvmsg handler msg_name and msg_namelen logic This patch now always passes msg->msg_namelen as 0. recvmsg handlers must set msg_namelen to the proper size <= sizeof(struct sockaddr_storage) to return msg_name to the user. This prevents numerous uninitialized memory leaks we had in the recvmsg handlers and makes it harder for new code to accidentally leak uninitialized memory. Optimize for the case recvfrom is called with NULL as address. We don't need to copy the address at all, so set it to NULL before invoking the recvmsg handler. We can do so, because all the recvmsg handlers must cope with the case a plain read() is called on them. read() also sets msg_name to NULL. Also document these changes in include/linux/net.h as suggested by David Miller. Changes since RFC: Set msg->msg_name = NULL if user specified a NULL in msg_name but had a non-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn't affect sendto as it would bail out earlier while trying to copy-in the address. It also more naturally reflects the logic by the callers of verify_iovec. With this change in place I could remove " if (!uaddr || msg_sys->msg_namelen == 0) msg->msg_name = NULL ". This change does not alter the user visible error logic as we ignore msg_namelen as long as msg_name is NULL. Also remove two unnecessary curly brackets in ___sys_recvmsg and change comments to netdev style.

4cd8587 Steven Rostedt 15 November 2013, 03:57:29 UTC btrfs: Use trace condition for get_extent tracepoint Doing an if statement to test some condition to know if we should trigger a tracepoint is pointless when tracing is disabled. This just adds overhead and wastes a branch prediction. This is why the TRACE_EVENT_CONDITION() was created. It places the check inside the jump label so that the branch does not happen unless tracing is enabled. That is, instead of doing: if (em) trace_btrfs_get_extent(root, em); Which is basically this: if (em) if (static_key(trace_btrfs_get_extent)) { Using a TRACE_EVENT_CONDITION() we can just do: trace_btrfs_get_extent(root, em); And the condition trace event will do: if (static_key(trace_btrfs_get_extent)) { if (em) { ... The static key is a non conditional jump (or nop) that is faster than having to check if em is NULL or not.

c13f20a Michael Neuling 20 November 2013, 05:18:54 UTC powerpc/signals: Mark VSX not saved with small contexts The VSX MSR bit in the user context indicates if the context contains VSX state. Currently we set this when the process has touched VSX at any stage. Unfortunately, if the user has not provided enough space to save the VSX state, we can't save it but we currently still set the MSR VSX bit. This patch changes this to clear the MSR VSX bit when the user doesn't provide enough space. This indicates that there is no valid VSX state in the user context. This is needed to support get/set/make/swapcontext for applications that use VSX but only provide a small context. For example, getcontext in glibc provides a smaller context since the VSX registers don't need to be saved over the glibc function call. But since the program calling getcontext may have used VSX, the kernel currently says the VSX state is valid when it's not. If the returned context is then used in setcontext (ie. a small context without VSX but with MSR VSX set), the kernel will refuse the context. This situation has been reported by the glibc community. Based on patch from Carlos O'Donell.

3eb906c Michael Ellerman 20 November 2013, 00:05:01 UTC powerpc: Make cpu_to_chip_id() available when SMP=n Up until now we have only used cpu_to_chip_id() in the topology code, which is only used on SMP builds. However my recent commit a4da0d5 "Implement arch_get_random_long/int() for powernv" added a usage when SMP=n, breaking the build. Move cpu_to_chip_id() into prom.c so it is available for SMP=n builds. We would move the extern to prom.h, but that breaks the include in topology.h. Instead we leave it in smp.h, but move it out of the CONFIG_SMP #ifdef. We also need to include asm/smp.h in rng.c, because the linux version skips asm/smp.h on UP. What a mess.

c610260 Li Zhong 19 November 2013, 08:11:37 UTC powerpc/vio: Fix a dma_mask issue of vio I encountered following issue: [ 0.283035] ibmvscsi 30000015: couldn't initialize event pool [ 5.688822] ibmvscsi: probe of 30000015 failed with error -1 which prevents the storage from being recognized, and the machine from booting. After some digging, it seems that it is caused by commit 4886c399da as dma_mask pointer in viodev->dev is not set, so in dma_set_mask_and_coherent(), dma_set_coherent_mask() is not called because dma_set_mask(), which is dma_set_mask_pSeriesLP() returned EIO. While before the commit, dma_set_coherent_mask() is always called. I tried to replace dma_set_mask_and_coherent() with dma_coerce_mask_and_coherent(), and the machine could boot again.

As a result, comparisons against the top 32 bits of high_slices (representing the top 32TB) always returns 0 and the top of our mmap region is clamped at 32TB This also breaks mmap randomisation since the randomised address is always up near the top of the address space and it gets clamped down to 32TB.

The toolchain folks confirmed it now, the new ABI is stable and merged with gcc, so we are all good. Oh and we actually missed the actual Kconfig switch for LE so here it is, along with a couple more bug fixes. I have more fixes but not related to LE so I'll send them as a separate pull request tomorrow, let's get this one out of the way. Note that this supports running user space binaries using the new ABI, but the kernel itself still needs to be built with the old one. We'll bring fixes for that after -rc1. Here's Anton log that goes with this series: This patch series adds support for the new ABI, LPAR support for H_SET_MODE and finally adds a kconfig option and defconfig. ABIv2 support was recently committed to binutils and gcc, and should be merged into glibc soon. There are a number of very nice improvements including the removal of function descriptors.

e7cc5cf Yinghai Lu 19 November 2013, 00:02:45 UTC PCI: Remove duplicate pci_disable_device() from pcie_portdrv_remove() The pcie_portdrv .probe() method calls pci_enable_device() once, in pcie_port_device_register(), but the .remove() method calls pci_disable_device() twice, in pcie_port_device_remove() and in pcie_portdrv_remove(). That causes a "disabling already-disabled device" warning when removing a PCIe port device. This happens all the time when removing Thunderbolt devices, but is also easy to reproduce with, e.g., "echo 0000:00:1c.3 > /sys/bus/pci/drivers/pcieport/unbind" This patch removes the disable from pcie_portdrv_remove().
