2017-09-19ipv6: fix net.ipv6.conf.all interface DAD handlersMatteo Croce2-11/+34
Currently, writing into net.ipv6.conf.all.{accept_dad,use_optimistic,optimistic_dad} has no effect. Fix handling of these flags by: - using the maximum of global and per-interface values for the accept_dad flag. That is, if at least one of the two values is non-zero, enable DAD on the interface. If at least one value is set to 2, enable DAD and disable IPv6 operation on the interface if MAC-based link-local address was found - using the logical OR of global and per-interface values for the optimistic_dad flag. If at least one of them is set to one, optimistic duplicate address detection (RFC 4429) is enabled on the interface - using the logical OR of global and per-interface values for the use_optimistic flag. If at least one of them is set to one, optimistic addresses won't be marked as deprecated during source address selection on the interface. While at it, as we're modifying the prototype for ipv6_use_optimistic_addr(), drop inline, and let the compiler decide.

2017-09-19net: ipv6: fix regression of no RTM_DELADDR sent after DAD failureMike Manning1-2/+3
Commit f784ad3d79e5 ("ipv6: do not send RTM_DELADDR for tentative addresses") incorrectly assumes that no RTM_NEWADDR are sent for addresses in tentative state, as this does happen for the standard IPv6 use-case of DAD failure, see the call to ipv6_ifa_notify() in addconf_dad_stop(). So as a result of this change, no RTM_DELADDR is sent after DAD failure for a link-local when strict DAD (accept_dad=2) is configured, or on the next admin down in other cases. The absence of this notification breaks backwards compatibility and causes problems after DAD failure if this notification was being relied on. The solution is to allow RTM_DELADDR to still be sent after DAD failure.

2017-09-19bpf: fix ri->map_owner pointer on bpf_prog_reallocDaniel Borkmann2-10/+21
Commit 109980b894e9 ("bpf: don't select potentially stale ri->map from buggy xdp progs") passed the pointer to the prog itself to be loaded into r4 prior on bpf_redirect_map() helper call, so that we can store the owner into ri->map_owner out of the helper. Issue with that is that the actual address of the prog is still subject to change when subsequent rewrites occur that require slow path in bpf_prog_realloc() to alloc more memory, e.g. from patching inlining helper functions or constant blinding. Thus, we really need to take prog->aux as the address we're holding, which also works with prog clones as they share the same aux object. Instead of then fetching aux->prog during runtime, which could potentially incur cache misses due to false sharing, we are going to just use aux for comparison on the map owner. This will also keep the patchlet of the same size, and later check in xdp_map_invalid() only accesses read-only aux pointer from the prog, it's also in the same cacheline already from prior access when calling bpf_func.

2017-09-19net: emac: Fix napi poll list corruptionChristian Lamparter1-2/+1
This patch is pretty much a carbon copy of commit 3079c652141f ("caif: Fix napi poll list corruption") with "caif" replaced by "emac". The commit d75b1ade567f ("net: less interrupt masking in NAPI") breaks emac. It is now required that if the entire budget is consumed when poll returns, the napi poll_list must remain empty. However, like some other drivers emac tries to do a last-ditch check and if there is more work it will call napi_reschedule and then immediately process some of this new work. Should the entire budget be consumed while processing such new work then we will violate the new caller contract. This patch fixes this by not touching any work when we reschedule in emac.

2017-09-19tcp: fastopen: fix on syn-data transmit failureEric Dumazet1-0/+9
Our recent change exposed a bug in TCP Fastopen Client that syzkaller found right away [1] When we prepare skb with SYN+DATA, we attempt to transmit it, and we update socket state as if the transmit was a success. In socket RTX queue we have two skbs, one with the SYN alone, and a second one containing the DATA. When (malicious) ACK comes in, we now complain that second one had no skb_mstamp. The proper fix is to make sure that if the transmit failed, we do not pretend we sent the DATA skb, and make it our send_head. When 3WHS completes, we can now send the DATA right away, without having to wait for a timeout.

2017-09-19ACPI / bus: Make ACPI_HANDLE() work for non-GPL code againJohn Hubbard2-14/+17
Due to commit db3e50f3234b (device property: Get rid of struct fwnode_handle type field), ACPI_HANDLE() inadvertently became a GPL-only call. The call path that led to that was: ACPI_HANDLE() ACPI_COMPANION() to_acpi_device_node() is_acpi_device_node() acpi_device_fwnode_ops DECLARE_ACPI_FWNODE_OPS(acpi_device_fwnode_ops); ...and the new DECLARE_ACPI_FWNODE_OPS() includes EXPORT_SYMBOL_GPL, whereas previously it was a static struct. In order to avoid changing any of that, let's instead provide ever so slightly better encapsulation of those struct fwnode_operations instances. Those do not really need to be directly used in inline function calls in header files. Simply moving two small functions (is_acpi_device_node and is_acpi_data_node) out of acpi_bus.h, and into a .c file, does that. That leaves the internals of struct fwnode_operations as GPL-only (which I think was the intent all along), but un-breaks any driver code out there that relies on the ACPI subsystem's being (historically) an EXPORT_SYMBOL-usable system. By that, I mean, ACPI_HANDLE() and other basic ACPI calls were non-GPL-protected. Also, while I'm there, remove a tiny bit of redundancy that was missed in the earlier commit, by having is_acpi_node() use the other two routines, instead of checking fwnode directly.

2017-09-19ALSA: asihpi: fix a potential double-fetch bug when copying puhmMeng Xu1-4/+8
The hm->h.size is intended to hold the actual size of the hm struct that is copied from userspace and should always be <= sizeof(*hm). However, after copy_from_user(hm, puhm, hm->h.size), since userspace process has full control over the memory region pointed by puhm, it is possible that the value of hm->h.size is different from what is fetched-in previously (get_user(hm->h.size, (u16 __user *)puhm)). In other words, hm->h.size is overriden and the relation between hm->h.size and the hm struct is broken. This patch proposes to use a seperate variable, msg_size, to hold the value of the first fetch and override hm->h.size to msg_size after the second fetch to maintain the relation.

04c81c7293df ("MIPS: PCI: Replace pci_fixup_irqs() call with host bridge IRQ mapping hooks") moved the PCI IRQ fixup to the new host bridge map/swizzle_irq() hooks mechanism. Those hooks can also be called after boot, when all the __init/__initdata/__initconst sections have been freed. Therefore, functions called by them (and the data they refer to) must not be marked as __init/__initdata/__initconst lest compilation trigger section mismatch warnings. Fix all the board files map_irq() hooks by simply removing the respective __init/__initdata/__initconst section markers and by adding another persistent hook IRQ map for the txx9 board files.

2017-09-19ceph: avoid panic in create_session_open_msg() if utsname() returns NULLYan, Zheng2-3/+7
utsname() can return NULL while process is exiting. Kernel releases file locks during process exits. We send request to mds when releasing file lock. So it's possible that we open mds session while process is exiting. utsname() is called in create_session_open_msg().

2017-09-19irqchip.mips-gic: Fix shared interrupt mask writesPaul Burton1-3/+3
The write_gic_smask() & write_gic_rmask() functions take a shared interrupt number as a parameter, but we're incorrectly providing them a bitmask with the shared interrupt's bit set. This effectively means that we mask or unmask the shared interrupt 1<<n rather than shared interrupt n, and as a result likely drop interrupts.

2017-09-19libceph: don't allow bidirectional swap of pg-upmap-itemsIlya Dryomov1-10/+25
This reverts most of commit f53b7665c8ce ("libceph: upmap semantic changes"). We need to prevent duplicates in the final result. For example, we can currently take [1,2,3] and apply [(1,2)] and get [2,2,3] or [1,2,3] and apply [(3,2)] and get [1,2,2] The rest of the system is not prepared to handle duplicates in the result set like this. The reverted piece was intended to allow [1,2,3] and [(1,2),(2,1)] to get [2,1,3] to reorder primaries. First, this bidirectional swap is hard to implement in a way that also prevents dups. For example, [1,2,3] and [(1,4),(2,3),(3,4)] would give [4,3,4] but would we just drop the last step we'd have [4,3,3] which is also invalid, etc. Simpler to just not handle bidirectional swaps. In practice, they are not needed: if you just want to choose a different primary then use primary_affinity, or pg_upmap (not pg_upmap_items).
