2017-02-24vxlan: don't allow overwrite of config src addrBrian Russell
When using IPv6 transport and a default dst, a pointer to the configured source address is passed into the route lookup. If no source address is configured, then the value is overwritten. IPv6 route lookup ignores egress ifindex match if the source address is set, so if egress ifindex match is desired, the source address must be passed as any. The overwrite breaks this for subsequent lookups. Avoid this by copying the configured address to an existing stack variable and pass a pointer to that instead.

2017-02-24rxrpc: Fix an assertion in rxrpc_read()Marc Dionne
In the rxrpc_read() function, which allows a user to read the contents of a key, we miscalculate the expected length of an encoded rxkad token by not taking into account the key length. However, the data is stored later anyway with an ENCODE_DATA() call - and an assertion failure then ensues when the lengths are checked at the end. Fix this by including the key length in the token size estimation. The following assertion is produced: Assertion failed - 384(0x180) == 380(0x17c) is false ------------[ cut here ]------------ kernel BUG at ../net/rxrpc/key.c:1221! invalid opcode: 0000 [#1] SMP Modules linked in: CPU: 2 PID: 2957 Comm: keyctl Not tainted 4.10.0-fscache+ #483 Hardware name: ASUS All Series/H97-PLUS, BIOS 2306 10/09/2014 task: ffff8804013a8500 task.stack: ffff8804013ac000 RIP: 0010:rxrpc_read+0x10de/0x11b6 RSP: 0018:ffff8804013afe48 EFLAGS: 00010296 RAX: 000000000000003b RBX: 0000000000000003 RCX: 0000000000000000 RDX: 0000000000040001 RSI: 00000000000000f6 RDI: 0000000000000300 RBP: ffff8804013afed8 R08: 0000000000000001 R09: 0000000000000001 R10: ffff8804013afd90 R11: 0000000000000002 R12: 00005575f7c911b4 R13: 00005575f7c911b3 R14: 0000000000000157 R15: ffff880408a5d640 FS: 00007f8dfbc73700(0000) GS:ffff88041fb00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00005575f7c91008 CR3: 000000040120a000 CR4: 00000000001406e0 Call Trace: keyctl_read_key+0xb6/0xd7 SyS_keyctl+0x83/0xe7 do_syscall_64+0x80/0x191 entry_SYSCALL64_slow_path+0x25/0x25 Signed-off-by: Marc Dionne <marc.dionne@auristor.com> Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: David S.

2017-02-24sctp: deny peeloff operation on asocs with threads sleeping on itMarcelo Ricardo Leitner
commit 2dcab5984841 ("sctp: avoid BUG_ON on sctp_wait_for_sndbuf") attempted to avoid a BUG_ON call when the association being used for a sendmsg() is blocked waiting for more sndbuf and another thread did a peeloff operation on such asoc, moving it to another socket. As Ben Hutchings noticed, then in such case it would return without locking back the socket and would cause two unlocks in a row. Further analysis also revealed that it could allow a double free if the application managed to peeloff the asoc that is created during the sendmsg call, because then sctp_sendmsg() would try to free the asoc that was created only for that call. This patch takes another approach. It will deny the peeloff operation if there is a thread sleeping on the asoc, so this situation doesn't exist anymore. This avoids the issues described above and also honors the syscalls that are already being handled (it can be multiple sendmsg calls). Joint work with Xin Long.

2017-02-24arm64/cpufeature: check correct field width when updating sys_valMark Rutland
When we're updating a register's sys_val, we use arm64_ftr_value() to find the new field value. We use cpuid_feature_extract_field() to find the new value, but this implicitly assumes a 4-bit field, so we may extract more bits than we mean to for fields like CTR_EL0.L1ip. This affects update_cpu_ftr_reg(), where we may extract erroneous values for ftr_cur and ftr_new. Depending on the additional bits extracted in either case, we may erroneously detect that the value is mismatched, and we'll try to compute a new safe value. Dependent on these extra bits and feature type, arm64_ftr_safe_value() may pessimistically select the always-safe value, or may erroneously choose either the extracted cur or new value as the safe option. The extra bits will subsequently be masked out in arm64_ftr_set_value(), so we may choose a higher value, yet write back a lower one. Fix this by passing the width down explicitly in arm64_ftr_value(), so we always extract the correct amount.

2017-02-24Revert "arm64: mm: set the contiguous bit for kernel mappings where appropriate"Mark Rutland
This reverts commit 0bfc445dec9dd8130d22c9f4476eed7598524129. When we change the permissions of regions mapped using contiguous entries, the architecture requires us to follow a Break-Before-Make strategy, breaking *all* associated entries before we can change any of the following properties from the entries: - presence of the contiguous bit - output address - attributes - permissiones Failure to do so can result in a number of problems (e.g. TLB conflict aborts and/or erroneous results from TLB lookups). See ARM DDI 0487A.k_iss10775, "Misprogramming of the Contiguous bit", page D4-1762. We do not take this into account when altering the permissions of kernel segments in mark_rodata_ro(), where we change the permissions of live contiguous entires one-by-one, leaving them transiently inconsistent. This has been observed to result in failures on some fast model configurations. Unfortunately, we cannot follow Break-Before-Make here as we'd have to unmap kernel text and data used to perform the sequence. For the timebeing, revert commit 0bfc445dec9dd813 so as to avoid issues resulting from this misuse of the contiguous bit.

2017-02-24rtc: ds3232: Call device_init_wakeup before device_registerPhil Reid
The wakealarm attribute is currently not exposed in the sysfs interface as the device has not been set as doing wakealarm when device_register is called. Changing the order of the calls fixes that problem. Interrupts are cleared in check_rtc_status prior to requesting the interrupt. This is only set if an irq is defined. If irq registration fails then set wakeup_capable to false. With this change the sysfs wakealarm attribute will be left visible but it is non functional. rtcwake still returns that the device is not enabled for wakeup.

2017-02-24objtool: Improve detection of BUG() and other dead endsJosh Poimboeuf
The BUG() macro's use of __builtin_unreachable() via the unreachable() macro tells gcc that the instruction is a dead end, and that it's safe to assume the current code path will not execute past the previous instruction. On x86, the BUG() macro is implemented with the 'ud2' instruction. When objtool's branch analysis sees that instruction, it knows the current code path has come to a dead end. Peter Zijlstra has been working on a patch to change the WARN macros to use 'ud2'. That patch will break objtool's assumption that 'ud2' is always a dead end. Generally it's best for objtool to avoid making those kinds of assumptions anyway. The more ignorant it is of kernel code internals, the better. So create a more generic way for objtool to detect dead ends by adding an annotation to the unreachable() macro. The annotation stores a pointer to the end of the unreachable code path in an '__unreachable' section. Objtool can read that section to find the dead ends.

2017-02-24sched/core: Fix update_rq_clock() splat on hotplug (and suspend/resume)Peter Zijlstra
The hotplug code still triggers the warning about using a stale rq->clock value. Fix things up to actually run update_rq_clock() in a place where we record the 'UPDATED' flag, and then modify the annotation to retain this flag over the rq->lock fiddling that happens as a result of actually migrating all the tasks elsewhere.

2017-02-24perf/core: Remove confusing comment and move put_ctx()Peter Zijlstra
Since commit: 321027c1fe77 ("perf/core: Fix concurrent sys_perf_event_open() vs. 'move_group' race") ... the code looks like (assuming move_group==1): gctx = __perf_event_ctx_lock_double(group_leader, ctx); perf_remove_from_context(group_leader, 0); list_for_each_entry(sibling, &group_leader->sibling_list, group_entry) { perf_remove_from_context(sibling, 0); put_ctx(gctx); } /* ... */ /* misleading comment about how this is the last reference */ put_ctx(gctx); perf_event_ctx_unlock(group_leader, gctx); What that 'last' put_ctx() does is drop @group_leader's reference on gctx after having dropped all its potential sibling references. But the thing is that __perf_event_ctx_lock_double() returns with a reference _and_ a held lock, and perf_event_ctx_unlock() unlocks that lock and drops that reference. Therefore that put_ctx() cannot be the 'last' of anything, nor is there an unbalance in puts. To reduce confusion, remove the comment and place the put_ctx() next to the remove_from_context() call.

2017-02-24s390/crypt: Add protected key AES moduleMartin Schwidefsky
This patch introduces a new in-kernel-crypto blockcipher called 'paes' which implements AES with protected keys. The paes blockcipher can be used similar to the aes blockcipher but uses secure key material to derive the working protected key and so offers an encryption implementation where never a clear key value is exposed in memory. The paes module is only available for the s390 platform providing a minimal hardware support of CPACF enabled with at least MSA level 3. Upon module initialization these requirements are checked. Includes additional contribution from Harald Freudenberger. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull namespace updates from Eric Biederman: "There is a lot here. A lot of these changes result in subtle user visible differences in kernel behavior. I don't expect anything will care but I will revert/fix things immediately if any regressions show up. From Seth Forshee there is a continuation of the work to make the vfs ready for unpriviled mounts. We had thought the previous changes prevented the creation of files outside of s_user_ns of a filesystem, but it turns we missed the O_CREAT path. Ooops. Pavel Tikhomirov and Oleg Nesterov worked together to fix a long standing bug in the implemenation of PR_SET_CHILD_SUBREAPER where only children that are forked after the prctl are considered and not children forked before the prctl. The only known user of this prctl systemd forks all children after the prctl. So no userspace regressions will occur. Holding earlier forked children to the same rules as later forked children creates a semantic that is sane enough to allow checkpoing of processes that use this feature. There is a long delayed change by Nikolay Borisov to limit inotify instances inside a user namespace. Michael Kerrisk extends the API for files used to maniuplate namespaces with two new trivial ioctls to allow discovery of the hierachy and properties of namespaces. Konstantin Khlebnikov with the help of Al Viro adds code that when a network namespace exits purges it's sysctl entries from the dcache. As in some circumstances this could use a lot of memory. Vivek Goyal fixed a bug with stacked filesystems where the permissions on the wrong inode were being checked. I continue previous work on ptracing across exec. Allowing a file to be setuid across exec while being ptraced if the tracer has enough credentials in the user namespace, and if the process has CAP_SETUID in it's own namespace. Proc files for setuid or otherwise undumpable executables are now owned by the root in the user namespace of their mm. Allowing debugging of setuid applications in containers to work better. A bug I introduced with permission checking and automount is now fixed. The big change is to mark the mounts that the kernel initiates as a result of an automount. This allows the permission checks in sget to be safely suppressed for this kind of mount. As the permission check happened when the original filesystem was mounted. Finally a special case in the mount namespace is removed preventing unbounded chains in the mount hash table, and making the semantics simpler which benefits CRIU. The vfs fix along with related work in ima and evm I believe makes us ready to finish developing and merge fully unprivileged mounts of the fuse filesystem. The cleanups of the mount namespace makes discussing how to fix the worst case complexity of umount. The stacked filesystem fixes pave the way for adding multiple mappings for the filesystem uids so that efficient and safer containers can be implemented" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: proc/sysctl: Don't grab i_lock under sysctl_lock. vfs: Use upper filesystem inode in bprm_fill_uid() proc/sysctl: prune stale dentries during unregistering mnt: Tuck mounts under others instead of creating shadow/side mounts. prctl: propagate has_child_subreaper flag to every descendant introduce the walk_process_tree() helper nsfs: Add an ioctl() to return owner UID of a userns fs: Better permission checking for submounts exit: fix the setns() && PR_SET_CHILD_SUBREAPER interaction vfs: open() with O_CREAT should not create inodes with unknown ids nsfs: Add an ioctl() to return the namespace type proc: Better ownership of files for non-dumpable tasks in user namespaces exec: Remove LSM_UNSAFE_PTRACE_CAP exec: Test the ptracer's saved cred to see if the tracee can gain caps exec: Don't reset euid and egid when the tracee has CAP_SETUID inotify: Convert to using per-namespace limits
