We missed two places that i_wrbuffer_ref_head, i_wr_ref, i_dirty_caps and i_flushing_caps may change. When they are all zeros, we should free i_head_snapc.

2019-04-23ceph: handle the case where a dentry has been renamed on outstanding reqJeff Layton
It's possible for us to issue a lookup to revalidate a dentry concurrently with a rename. If done in the right order, then we could end up processing dentry info in the reply that no longer reflects the state of the dentry. If req->r_dentry->d_name differs from the one in the trace, then just ignore the trace in the reply. We only need to do this however if the parent's i_rwsem is not held.

2019-04-23ceph: only use d_name directly when parent is lockedJeff Layton
Ben reported tripping the BUG_ON in create_request_message during some performance testing. Analysis of the vmcore showed that the length of the r_dentry->d_name string changed after we allocated the buffer, but before we encoded it. build_dentry_path returns pointers to d_name in the common case of non-snapped dentries, but this optimization isn't safe unless the parent directory is locked. When it isn't, have the code make a copy of the d_name while holding the d_lock.

2019-04-23ARM: 8857/1: efi: enable CP15 DMB instructions before cleaning the cacheArd Biesheuvel
The EFI stub is entered with the caches and MMU enabled by the firmware, and once the stub is ready to hand over to the decompressor, we clean and disable the caches. The cache clean routines use CP15 barrier instructions, which can be disabled via SCTLR. Normally, when using the provided cache handling routines to enable the caches and MMU, this bit is enabled as well. However, but since we entered the stub with the caches already enabled, this routine is not executed before we call the cache clean routines, resulting in undefined instruction exceptions if the firmware never enabled this bit. So set the bit explicitly in the EFI entry code, but do so in a way that guarantees that the resulting code can still run on v6 cores as well (which are guaranteed to have CP15 barriers enabled) Cc: <stable@vger.kernel.org> # v4.9+ Acked-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

2019-04-23ARM: fix function graph tracer and unwinder dependenciesRussell King
Naresh Kamboju recently reported that the function-graph tracer crashes on ARM. The function-graph tracer assumes that the kernel is built with frame pointers. We explicitly disabled the function-graph tracer when building Thumb2, since the Thumb2 ABI doesn't have frame pointers. We recently changed the way the unwinder method was selected, which seems to have made it more likely that we can end up with the function- graph tracer enabled but without the kernel built with frame pointers. Fix up the function graph tracer dependencies so the option is not available when we have no possibility of having frame pointers, and adjust the dependencies on the unwinder option to hide the non-frame pointer unwinder options if the function-graph tracer is enabled.

2019-04-22nfsd: wake blocked file lock waiters before sending callbackJeff Layton
When a blocked NFS lock is "awoken" we send a callback to the server and then wake any hosts waiting on it. If a client attempts to get a lock and then drops off the net, we could end up waiting for a long time until we end up waking locks blocked on that request. So, wake any other waiting lock requests before sending the callback. Do this by calling locks_delete_block in a new "prepare" phase for CB_NOTIFY_LOCK callbacks.

2019-04-22nfsd: wake waiters blocked on file_lock before deleting itJeff Layton
After a blocked nfsd file_lock request is deleted, knfsd will send a callback to the client and then free the request. Commit 16306a61d3b7 ("fs/locks: always delete_block after waiting.") changed it such that locks_delete_block is always called on a request after it is awoken, but that patch missed fixing up blocked nfsd request handling. Call locks_delete_block on the block to wake up any locks still blocked on the nfsd lock request before freeing it. Some of its callers already do this however, so just remove those calls.

2019-04-22x86/boot: Disable RSDP parsing temporarilyBorislav Petkov
The original intention to move RDSP parsing very early, before KASLR does its ranges selection, was to accommodate movable memory regions machines (CONFIG_MEMORY_HOTREMOVE) to still be able to do memory hotplug. However, that broke kexec'ing a kernel on EFI machines because depending on where the EFI systab was mapped, on at least one machine it isn't present in the kexec mapping of the second kernel, leading to a triple fault in the early code. Fixing this properly requires significantly involved surgery and we cannot allow ourselves to do that, that close to the merge window. So disable the RSDP parsing code temporarily until it is fixed properly in the next release cycle.

To fix the bogus "start" time seen with conntrack timestamping for outgoing packets, never use skb->tstamp and always use current time. 2. In nfqueue and nflog, only use skb->tstamp for incoming packets, as determined by current hook (prerouting, input, forward). 3. xt_time has to use system clock as well rather than skb->tstamp.
