2018-08-16tracing/blktrace: Fix to allow setting same valueSteven Rostedt (VMware)
Masami Hiramatsu reported: Current trace-enable attribute in sysfs returns an error if user writes the same setting value as current one, e.g. # cat /sys/block/sda/trace/enable 0 # echo 0 > /sys/block/sda/trace/enable bash: echo: write error: Invalid argument # echo 1 > /sys/block/sda/trace/enable # echo 1 > /sys/block/sda/trace/enable bash: echo: write error: Device or resource busy But this is not a preferred behavior, it should ignore if new setting is same as current one. This fixes the problem as below. # cat /sys/block/sda/trace/enable 0 # echo 0 > /sys/block/sda/trace/enable # echo 1 > /sys/block/sda/trace/enable # echo 1 > /sys/block/sda/trace/enable Link: http://lkml.kernel.org/r/20180816103802.08678002@gandalf.local.home Cc: Ingo Molnar <mingo@redhat.com> Cc: Jens Axboe <axboe@kernel.dk> Cc: linux-block@vger.kernel.org Cc: stable@vger.kernel.org Fixes: cd649b8bb830d ("blktrace: remove sysfs_blk_trace_enable_show/store()") Reported-by: Masami Hiramatsu <mhiramat@kernel.org> Tested-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>

2018-08-16bpf: fix a rcu usage warning in bpf_prog_array_copy_core()Yonghong Song
Commit 394e40a29788 ("bpf: extend bpf_prog_array to store pointers to the cgroup storage") refactored the bpf_prog_array_copy_core() to accommodate new structure bpf_prog_array_item which contains bpf_prog array itself. In the old code, we had perf_event_query_prog_array(): mutex_lock(...) bpf_prog_array_copy_call(): prog = rcu_dereference_check(array, 1)->progs bpf_prog_array_copy_core(prog, ...) mutex_unlock(...) With the above commit, we had perf_event_query_prog_array(): mutex_lock(...) bpf_prog_array_copy_call(): bpf_prog_array_copy_core(array, ...): item = rcu_dereference(array)->items; ... mutex_unlock(...) The new code will trigger a lockdep rcu checking warning. The fix is to change rcu_dereference() to rcu_dereference_check() to prevent such a warning.

2018-08-16samples/bpf: all XDP samples should unload xdp/bpf prog on SIGTERMJesper Dangaard Brouer
It is common XDP practice to unload/deattach the XDP bpf program, when the XDP sample program is Ctrl-C interrupted (SIGINT) or killed (SIGTERM). The samples/bpf programs xdp_redirect_cpu and xdp_rxq_info, forgot to trap signal SIGTERM (which is the default signal used by the kill command). This was discovered by Red Hat QA, which automated scripts depend on killing the XDP sample program after a timeout period.

2018-08-16ila: make lockdep happy againCong Wang
Previously, alloc_ila_locks() and bucket_table_alloc() call spin_lock_init() separately, therefore they have two different lock names and lock class keys. However, after commit b893281715ab ("ila: Call library function alloc_bucket_locks") they both call helper alloc_bucket_spinlocks() which now only has one lock name and lock class key. This causes a few bogus lockdep warnings as reported by syzbot. Fix this by making alloc_bucket_locks() a macro and pass declaration name as lock name and a static lock class key inside the macro.

2018-08-16block, bfq: reduce write overchargePaolo Valente
When a sync request is dispatched, the queue that contains that request, and all the ancestor entities of that queue, are charged with the number of sectors of the request. In constrast, if the request is async, then the queue and its ancestor entities are charged with the number of sectors of the request, multiplied by an overcharge factor. This throttles the bandwidth for async I/O, w.r.t. to sync I/O, and it is done to counter the tendency of async writes to steal I/O throughput to reads. On the opposite end, the lower this parameter, the stabler I/O control, in the following respect. The lower this parameter is, the less the bandwidth enjoyed by a group decreases - when the group does writes, w.r.t. to when it does reads; - when other groups do reads, w.r.t. to when they do writes. The fixes "block, bfq: always update the budget of an entity when needed" and "block, bfq: readd missing reset of parent-entity service" improved I/O control in bfq to such an extent that it has been possible to revise this overcharge factor downwards.

2018-08-16netfilter: x_tables: do not fail xt_alloc_table_info too easillyMichal Hocko
eacd86ca3b03 ("net/netfilter/x_tables.c: use kvmalloc() in xt_alloc_table_info()") has unintentionally fortified xt_alloc_table_info allocation when __GFP_RETRY has been dropped from the vmalloc fallback. Later on there was a syzbot report that this can lead to OOM killer invocations when tables are too large and 0537250fdc6c ("netfilter: x_tables: make allocation less aggressive") has been merged to restore the original behavior. Georgi Nikolov however noticed that he is not able to install his iptables anymore so this can be seen as a regression. The primary argument for 0537250fdc6c was that this allocation path shouldn't really trigger the OOM killer and kill innocent tasks. On the other hand the interface requires root and as such should allow what the admin asks for. Root inside a namespaces makes this more complicated because those might be not trusted in general. If they are not then such namespaces should be restricted anyway. Therefore drop the __GFP_NORETRY and replace it by __GFP_ACCOUNT to enfore memcg constrains on it.

2018-08-16netfilter: nf_tables: don't prevent event handler from device cleanup on ↵Florian Westphal
netns exit When a netnsamespace exits, the nf_tables pernet_ops will remove all rules. However, there is one caveat: Base chains that register ingress hooks will cause use-after-free: device is already gone at that point. The device event handlers prevent this from happening: netns exit synthesizes unregister events for all devices. However, an improper fix for a race condition made the notifiers a no-op in case they get called from netns exit path, so revert that part. This is safe now as the previous patch fixed nf_tables pernet ops and device notifier initialisation ordering.

Shaochun Chen points out we leak dumper filter state allocations stored in dump_control->data in case there is an error before netlink sets cb_running (after which ->done will be called at some point). In order to fix this, add .start functions and move allocations there. Same pattern as used in commit 90fd131afc565159c9e0ea742f082b337e10f8c6 ("netfilter: nf_tables: move dumper state allocation into ->start").

2018-08-16netfilter: nft_set: fix allocation size overflow in privsize callback.Taehee Yoo
In order to determine allocation size of set, ->privsize is invoked. At this point, both desc->size and size of each data structure of set are used. desc->size means number of element that is given by user. desc->size is u32 type. so that upperlimit of set element is 4294967295. but return type of ->privsize is also u32. hence overflow can occurred. test commands: %nft add table ip filter %nft add set ip filter hash1 { type ipv4_addr \; size 4294967295 \; } %nft list ruleset splat looks like: [ 1239.202910] kasan: CONFIG_KASAN_INLINE enabled [ 1239.208788] kasan: GPF could be caused by NULL-ptr deref or user memory access [ 1239.217625] general protection fault: 0000 [#1] SMP DEBUG_PAGEALLOC KASAN PTI [ 1239.219329] CPU: 0 PID: 1603 Comm: nft Not tainted 4.18.0-rc5+ #7 [ 1239.229091] RIP: 0010:nft_hash_walk+0x1d2/0x310 [nf_tables_set] [ 1239.229091] Code: 84 d2 7f 10 4c 89 e7 89 44 24 38 e8 d8 5a 17 e0 8b 44 24 38 48 8d 7b 10 41 0f b6 0c 24 48 89 fa 48 89 fe 48 c1 ea 03 83 e6 07 <42> 0f b6 14 3a 40 38 f2 7f 1a 84 d2 74 16 [ 1239.229091] RSP: 0018:ffff8801118cf358 EFLAGS: 00010246 [ 1239.229091] RAX: 0000000000000000 RBX: 0000000000020400 RCX: 0000000000000001 [ 1239.229091] RDX: 0000000000004082 RSI: 0000000000000000 RDI: 0000000000020410 [ 1239.229091] RBP: ffff880114d5a988 R08: 0000000000007e94 R09: ffff880114dd8030 [ 1239.229091] R10: ffff880114d5a988 R11: ffffed00229bb006 R12: ffff8801118cf4d0 [ 1239.229091] R13: ffff8801118cf4d8 R14: 0000000000000000 R15: dffffc0000000000 [ 1239.229091] FS: 00007f5a8fe0b700(0000) GS:ffff88011b600000(0000) knlGS:0000000000000000 [ 1239.229091] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 1239.229091] CR2: 00007f5a8ecc27b0 CR3: 000000010608e000 CR4: 00000000001006f0 [ 1239.229091] Call Trace: [ 1239.229091] ?

2018-08-16ipvs: don't show negative times in ip_vs_connMatteo Croce
Since commit 500462a9de65 ("timers: Switch to a non-cascading wheel"), timers duration can last even 12.5% more than the scheduled interval. IPVS has two handlers, /proc/net/ip_vs_conn and /proc/net/ip_vs_conn_sync, which shows the remaining time before that a connection expires. The default expire time for a connection is 60 seconds, and the expiration timer can fire even 4 seconds later than the scheduled time. The expiration time is calculated subtracting jiffies to the scheduled expiration time, and it's shown as a huge number when the timer fires late, since both values are unsigned. This can confuse script and tools which relies on it, like ipvsadm: root@mcroce-redhat:~# while ipvsadm -lc |grep SYN_RECV; do sleep 1 ; done TCP 00:05 SYN_RECV [fc00:1::1]:55732 [fc00:1::2]:8000 [fc00:2000::1]:8000 TCP 00:04 SYN_RECV [fc00:1::1]:55732 [fc00:1::2]:8000 [fc00:2000::1]:8000 TCP 00:03 SYN_RECV [fc00:1::1]:55732 [fc00:1::2]:8000 [fc00:2000::1]:8000 TCP 00:02 SYN_RECV [fc00:1::1]:55732 [fc00:1::2]:8000 [fc00:2000::1]:8000 TCP 00:01 SYN_RECV [fc00:1::1]:55732 [fc00:1::2]:8000 [fc00:2000::1]:8000 TCP 00:00 SYN_RECV [fc00:1::1]:55732 [fc00:1::2]:8000 [fc00:2000::1]:8000 TCP 68719476:44 SYN_RECV [fc00:1::1]:55732 [fc00:1::2]:8000 [fc00:2000::1]:8000 TCP 68719476:43 SYN_RECV [fc00:1::1]:55732 [fc00:1::2]:8000 [fc00:2000::1]:8000 TCP 68719476:42 SYN_RECV [fc00:1::1]:55732 [fc00:1::2]:8000 [fc00:2000::1]:8000 TCP 68719476:41 SYN_RECV [fc00:1::1]:55732 [fc00:1::2]:8000 [fc00:2000::1]:8000 TCP 68719476:40 SYN_RECV [fc00:1::1]:55732 [fc00:1::2]:8000 [fc00:2000::1]:8000 TCP 68719476:39 SYN_RECV [fc00:1::1]:55732 [fc00:1::2]:8000 [fc00:2000::1]:8000 Signed-off-by: Matteo Croce <mcroce@redhat.com> Acked-by: Simon Horman <horms@verge.net.au> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2018-08-16ipvs: fix race between ip_vs_conn_new() and ip_vs_del_dest()Tan Hu
We came across infinite loop in ipvs when using ipvs in docker env. When ipvs receives new packets and cannot find an ipvs connection, it will create a new connection, then if the dest is unavailable (i.e. IP_VS_DEST_F_AVAILABLE), the packet will be dropped sliently. But if the dropped packet is the first packet of this connection, the connection control timer never has a chance to start and the ipvs connection cannot be released. This will lead to memory leak, or infinite loop in cleanup_net() when net namespace is released like this: ip_vs_conn_net_cleanup at ffffffffa0a9f31a [ip_vs] __ip_vs_cleanup at ffffffffa0a9f60a [ip_vs] ops_exit_list at ffffffff81567a49 cleanup_net at ffffffff81568b40 process_one_work at ffffffff810a851b worker_thread at ffffffff810a9356 kthread at ffffffff810b0b6f ret_from_fork at ffffffff81697a18 race condition: CPU1 CPU2 ip_vs_in() ip_vs_conn_new() ip_vs_del_dest() __ip_vs_unlink_dest() ~IP_VS_DEST_F_AVAILABLE cp->dest && !IP_VS_DEST_F_AVAILABLE __ip_vs_conn_put ... cleanup_net ---> infinite looping Fix this by checking whether the timer already started.

2018-08-16Fix kexec forbidding kernels signed with keys in the secondary keyring to bootYannik Sembritzki
The split of .system_keyring into .builtin_trusted_keys and .secondary_trusted_keys broke kexec, thereby preventing kernels signed by keys which are now in the secondary keyring from being kexec'd. Fix this by passing VERIFY_USE_SECONDARY_KEYRING to verify_pefile_signature().
