2019-01-11powerpc/4xx/ocm: Fix fix for phys_addr_t printf warningsMichael Ellerman
My recent commit to fix the printf warnings in ocm.c got the format specifier wrong, because I copied it from the documentation without realising the square brackets are not meant as literals.

More generally, there's no need to define an IOMMU group for opencapi, as the device sends real addresses directly (admittedly, the virtualization story is yet to be written). So let's fix it by skipping the IOMMU group setup for opencapi PHBs.

2019-01-11powerpc/tm: Limit TM code inside PPC_TRANSACTIONAL_MEMBreno Leitao
Commit e1c3743e1a20 ("powerpc/tm: Set MSR[TS] just prior to recheckpoint") moved a code block around and this block uses a 'msr' variable outside of the CONFIG_PPC_TRANSACTIONAL_MEM, however the 'msr' variable is declared inside a CONFIG_PPC_TRANSACTIONAL_MEM block, causing a possible error when CONFIG_PPC_TRANSACTION_MEM is not defined. error: 'msr' undeclared (first use in this function) This is not causing a compilation error in the mainline kernel, because 'msr' is being used as an argument of MSR_TM_ACTIVE(), which is defined as the following when CONFIG_PPC_TRANSACTIONAL_MEM is *not* set: #define MSR_TM_ACTIVE(x) 0 This patch just fixes this issue avoiding the 'msr' variable usage outside the CONFIG_PPC_TRANSACTIONAL_MEM block, avoiding trusting in the MSR_TM_ACTIVE() definition.

2019-01-11binderfs: reserve devices for initial mountChristian Brauner
The binderfs instance in the initial ipc namespace will always have a reserve of 4 binder devices unless explicitly capped by specifying a lower value via the "max" mount option. This ensures when binder devices are removed (on accident or on purpose) they can always be recreated without risking that all minor numbers have already been used up.

2019-01-11ARM: integrator: impd1: use struct_size() in devm_kzalloc()Gustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

2019-01-11iommu/of: Fix probe-deferralRobin Murphy
Whilst iommu_probe_device() does check for non-NULL ops as the previous code did, it does not do so in the same order relative to the other checks, and as a result means that -EPROBE_DEFER returned by of_xlate() (plus any real error condition too) gets overwritten with -EINVAL and leads to various misbehaviour. Reinstate the original logic, but without implicitly relying on ops being set to infer !err as the initial condition (now that the validity of ops for its own sake is checked elsewhere).

Commit 8772c8bc093b ("tools: bpftool: support pretty print with kind_flag set") added bpftool map dump with kind_flag support. When bitfield_size can be retrieved directly from btf_member, function btf_dumper_bitfield() is called to dump the bitfield. The implementation passed the wrong parameter "bit_offset" to the function. The excepted value is the bit_offset within a byte while the passed-in value is the struct member offset. This commit fixed the bug with passing correct "bit_offset" with adjusted data pointer.

2019-01-11bpf: fix bpffs bitfield pretty printYonghong Song
Commit 9d5f9f701b18 ("bpf: btf: fix struct/union/fwd types with kind_flag") introduced kind_flag and used bitfield_size in the btf_member to directly pretty print member values. The commit contained a bug where the incorrect parameters could be passed to function btf_bitfield_seq_show(). The bits_offset parameter in the function expects a value less than 8. Instead, the member offset in the structure is passed. The below is btf_bitfield_seq_show() func signature: void btf_bitfield_seq_show(void *data, u8 bits_offset, u8 nr_bits, struct seq_file *m) both bits_offset and nr_bits are u8 type. If the bitfield member offset is greater than 256, incorrect value will be printed. This patch fixed the issue by calculating correct proper data offset and bits_offset similar to non kind_flag case.

2019-01-11binderfs: implement "max" mount optionChristian Brauner
Since binderfs can be mounted by userns root in non-initial user namespaces some precautions are in order. First, a way to set a maximum on the number of binder devices that can be allocated per binderfs instance and second, a way to reserve a reasonable chunk of binderfs devices for the initial ipc namespace. A first approach as seen in [1] used sysctls similiar to devpts but was shown to be flawed (cf. [2] and [3]) since some aspects were unneeded. This is an alternative approach which avoids sysctls completely and instead switches to a single mount option. Starting with this commit binderfs instances can be mounted with a limit on the number of binder devices that can be allocated. The max=<count> mount option serves as a per-instance limit. If max=<count> is set then only <count> number of binder devices can be allocated in this binderfs instance. This allows to safely bind-mount binderfs instances into unprivileged user namespaces since userns root in a non-initial user namespace cannot change the mount option as long as it does not own the mount namespace the binderfs mount was created in and hence cannot drain the host of minor device numbers [1]: https://lore.kernel.org/lkml/20181221133909.18794-1-christian@brauner.io/ [2]; https://lore.kernel.org/lkml/20181221163316.GA8517@kroah.com/ [3]: https://lore.kernel.org/lkml/CAHRSSEx+gDVW4fKKK8oZNAir9G5icJLyodO8hykv3O0O1jt2FQ@mail.gmail.com/ [4]: https://lore.kernel.org/lkml/20181221192044.5yvfnuri7gdop4rs@brauner.io/ Cc: Todd Kjos <tkjos@google.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Christian Brauner <christian.brauner@ubuntu.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

"FCLK" is "fixed_pll" which is running at 2550MHz. The "turbo" setting is described by "turbo_clock = 4" where 4 is the index of the table above.

Add a compatible string for the Mali-450 GPU on Amlogic Meson8 and Meson8b SoCs. Meson8 uses an "MP6" variant with six pixel processors while Meson8b (as cost-reduced SoC) uses an "MP2" variant with two pixel processors. Both have a reset line to bring the GPU into a well-defined state.

As part of audit process to update drivers to use rdma_restrack_add() ensure that QP objects is cleared before access. Such change fixes the crash observed with uninitialized non zero sgid attr accessed by ib_destroy_qp().

2019-01-11netfilter: nft_flow_offload: fix interaction with vrf slave devicewenxu
In the forward chain, the iif is changed from slave device to master vrf device. Thus, flow offload does not find a match on the lower slave device. This patch uses the cached route, ie. dst->dev, to update the iif and oif fields in the flow entry. After this patch, the following example works fine: # ip addr add dev eth0 1.1.1.1/24 # ip addr add dev eth1 10.0.0.1/24 # ip link add user1 type vrf table 1 # ip l set user1 up # ip l set dev eth0 master user1 # ip l set dev eth1 master user1 # nft add table firewall # nft add flowtable f fb1 { hook ingress priority 0 \; devices = { eth0, eth1 } \; } # nft add chain f ftb-all {type filter hook forward priority 0 \; policy accept \; } # nft add rule f ftb-all ct zone 1 ip protocol tcp flow offload @fb1 # nft add rule f ftb-all ct zone 1 ip protocol udp flow offload @fb1 Signed-off-by: wenxu <wenxu@ucloud.cn> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2019-01-11netfilter: ebtables: account ebt_table_info to kmemcgShakeel Butt
The [ip,ip6,arp]_tables use x_tables_info internally and the underlying memory is already accounted to kmemcg. Do the same for ebtables. The syzbot, by using setsockopt(EBT_SO_SET_ENTRIES), was able to OOM the whole system from a restricted memcg, a potential DoS. By accounting the ebt_table_info, the memory used for ebt_table_info can be contained within the memcg of the allocating process. However the lifetime of ebt_table_info is independent of the allocating process and is tied to the network namespace. So, the oom-killer will not be able to relieve the memory pressure due to ebt_table_info memory. The memory for ebt_table_info is allocated through vmalloc. Currently vmalloc does not handle the oom-killed allocating process correctly and one large allocation can bypass memcg limit enforcement. So, with this patch, at least the small allocations will be contained. For large allocations, we need to fix vmalloc.
