The current annotation is wrong as it says that we're only called under spinlock. In fact it should be marked as under either spinlock or RCU read lock. Fixes: da20420f ("rhashtable: Add nested tables") Reported-by:

Dan Carpenter reported a use before NULL check bug in the function bucket_table_free. In fact we don't need the NULL check at all as no caller can provide a NULL argument. So this patch fixes this by simply removing it. Reported-by:

Calls made through the in-kernel interface can end up getting stuck because of a missed variable update in a loop in rxrpc_recvmsg_data(). The problem is like this: (1) A new packet comes in and doesn't cause a notification to be given to the client as there's still another packet in the ring - the assumption being that if the client will keep drawing off data until the ring is empty. (2) The client is in rxrpc_recvmsg_data(), inside the big while loop that iterates through the packets. This copies the window pointers into variables rather than using the information in the call struct because: (a) MSG_PEEK might be in effect; (b) we need a barrier after reading call->rx_top to pair with the barrier in the softirq routine that loads the buffer. (3) The reading of call->rx_top is done outside of the loop, and top is never updated whilst we're in the loop. This means that even through there's a new packet available, we don't see it and may return -EFAULT to the caller - who will happily return to the scheduler and await the next notification. (4) No further notifications are forthcoming until there's an abort as the ring isn't empty. The fix is to move the read of call->rx_top inside the loop - but it needs to be done before the condition is checked. Reported-by:Marc Dionne <marc.dionne@auristor.com> Signed-off-by:

When tc actions are loaded as a module and no actions have been installed, flushing them would result in actions removed from the memory, but modules reference count not being decremented, so that the modules would not be unloaded.

Commit 5e1859fb ("ipv4: ipmr: various fixes and cleanups") fixed the issue for ipv4 ipmr: ip_mroute_setsockopt() & ip_mroute_getsockopt() should not access/set raw_sk(sk)->ipmr_table before making sure the socket is a raw socket, and protocol is IGMP The same fix should be done for ipv6 ipmr as well. This patch can fix the panic caused by overwriting the same offset as ipmr_table as in raw_sk(sk) when accessing other type's socket by ip_mroute_setsockopt(). Signed-off-by:

Commit b8607805 ("sctp: not copying duplicate addrs to the assoc's bind address list") tried to check for duplicate address before copying to asoc's bind_addr list from global addr list. But all the addrs' sin_ports in global addr list are 0 while the addrs' sin_ports are bp->port in asoc's bind_addr list. It means even if it's a duplicate address, af->cmp_addr will still return 0 as the their sin_ports are different. This patch is to fix it by setting the sin_port for addr param with bp->port before comparing the addrs.

The cited commit makes a great job of finding optimal shift/multiplier values assuming a 10 seconds wrap around, but forgot to change the overflow_period computation. It overflows in cyclecounter_cyc2ns(), and the final result is 804 ms, which is silly. Lets simply use 5 seconds, no need to recompute this, given how it is supposed to work. Later, we will use a timer instead of a work queue, since the new RX allocation schem will no longer need mlx4_en_recover_from_oom() and the service_task firing every 250 ms.

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.

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:

commit 2dcab598 ("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.

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

Pull ARM SoC platform updates from Arnd Bergmann: "In the SoC branch we normally collect classic arch/arm/mach-* contents, i.e. C code changes for SoC platforms. This release cycle the diffstat is quite nice, in that we're removing 3x the amount of code that's being added. The main reason for this is that there's a removal of camera drivers for Freescale i.MX chips (driver was removed so the device registration isn't needed any more). There's also removal of display initialization code for OMAP that is no longer needed. The rest are mostly minor tweaks and cleanups; constification on Samsung platforms, cleanup of ux500 platform data, purge of other unused platform data/device seutp on i.MX and other good stuff.
