2016-11-28x86/build: Remove three unneeded genhdr-y entriesPaul Bolle
In x86's include/asm/Kbuild three entries are appended to the genhdr-y make variable: genhdr-y += unistd_32.h genhdr-y += unistd_64.h genhdr-y += unistd_x32.h The same entries are also appended to that variable in include/uapi/asm/Kbuild. So commit: 10b63956fce7 ("UAPI: Plumb the UAPI Kbuilds into the user header installation and checking") ... removed these three entries from include/asm/Kbuild. But, apparently, some merge conflict resolution re-added them. The net effect is, in short, that the genhdr-y make variable contains these file names twice and, as a consequence, that the corresponding headers get installed twice. And so the build prints: INSTALL usr/include/asm/ (65 files) ... while in reality only 62 files are installed in that directory. Nothing breaks because of all that, but it's a good idea to finally remove these unneeded entries nevertheless.

2016-11-28x86/build: Don't use $(LINUXINCLUDE) twicePaul Bolle
The make variable KBUILD_CFLAGS contains $(LINUXINCLUDE). But the build already picks up $(LINUXINCLUDE) from scripts/Makefile.lib. The net effect is that the (long) list of include directories is used twice. This is harmless but pointless. So stop using $(LINUXINCLUDE) twice.

2016-11-28x86/boot/64: Optimize fixmap page fixupBorislav Petkov
Single-stepping through head_64.S made me look at the fixmap page PTEs fixup loop: So we're going through the whole level2_fixmap_pgt 4K page, looking at whether PAGE_PRESENT is set in those PTEs and add the delta between where we're compiled to run and where we actually end up running. However, if that delta is 0 (most cases) we go through all those 512 PTEs for no reason at all. Oh well, we add 0 but that's no reason to me. Skipping that useless fixup gives us a boot speedup of 0.004 seconds in my guest. Not a lot but considering how cheap it is, I'll take it. Here is the printk time difference: before: ...

2016-11-27bpf: fix multiple issues in selftest suite and samplesDaniel Borkmann
1) The test_lru_map and test_lru_dist fails building on my machine since the sys/resource.h header is not included. 2) test_verifier fails in one test case where we try to call an invalid function, since the verifier log output changed wrt printing function names. 3) Current selftest suite code relies on sysconf(_SC_NPROCESSORS_CONF) for retrieving the number of possible CPUs. This is broken at least in our scenario and really just doesn't work. glibc tries a number of things for retrieving _SC_NPROCESSORS_CONF. First it tries equivalent of /sys/devices/system/cpu/cpu[0-9]* | wc -l, if that fails, depending on the config, it either tries to count CPUs in /proc/cpuinfo, or returns the _SC_NPROCESSORS_ONLN value instead. If /proc/cpuinfo has some issue, it returns just 1 worst case. This oddity is nothing new [1], but semantics/behaviour seems to be settled. _SC_NPROCESSORS_ONLN will parse /sys/devices/system/cpu/online, if that fails it looks into /proc/stat for cpuX entries, and if also that fails for some reason, /proc/cpuinfo is consulted (and returning 1 if unlikely all breaks down). While that might match num_possible_cpus() from the kernel in some cases, it's really not guaranteed with CPU hotplugging, and can result in a buffer overflow since the array in user space could have too few number of slots, and on perpcu map lookup, the kernel will write beyond that memory of the value buffer. William Tu reported such mismatches: [...] The fact that sysconf(_SC_NPROCESSORS_CONF) != num_possible_cpu() happens when CPU hotadd is enabled. For example, in Fusion when setting vcpu.hotadd = "TRUE" or in KVM, setting ./qemu-system-x86_64 -smp 2, maxcpus=4 ... the num_possible_cpu() will be 4 and sysconf() will be 2 [2]. [...] Documentation/cputopology.txt says /sys/devices/system/cpu/possible outputs cpu_possible_mask. That is the same as in num_possible_cpus(), so first step would be to fix the _SC_NPROCESSORS_CONF calls with our own implementation. Later, we could add support to bpf(2) for passing a mask via CPU_SET(3), for example, to just select a subset of CPUs. BPF samples code needs this fix as well (at least so that people stop copying this). Thus, define bpf_num_possible_cpus() once in selftests and import it from there for the sample code to avoid duplicating it. The remaining sysconf(_SC_NPROCESSORS_CONF) in samples are unrelated. After all three issues are fixed, the test suite runs fine again: # make run_tests | grep self selftests: test_verifier [PASS] selftests: test_maps [PASS] selftests: test_lru_map [PASS] selftests: test_kmod.sh [PASS] [1] https://www.sourceware.org/ml/libc-alpha/2011-06/msg00079.html [2] https://www.mail-archive.com/netdev@vger.kernel.org/msg121183.html Fixes: 3059303f59cf ("samples/bpf: update tracex[23] examples to use per-cpu maps") Fixes: 86af8b4191d2 ("Add sample for adding simple drop program to link") Fixes: df570f577231 ("samples/bpf: unit test for BPF_MAP_TYPE_PERCPU_ARRAY") Fixes: e15596717948 ("samples/bpf: unit test for BPF_MAP_TYPE_PERCPU_HASH") Fixes: ebb676daa1a3 ("bpf: Print function name in addition to function id") Fixes: 5db58faf989f ("bpf: Add tests for the LRU bpf_htab") Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Cc: William Tu <u9012063@gmail.com> Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: David S.

2016-11-27bpf: add owner_prog_type and accounted mem to array map's fdinfoDaniel Borkmann
Allow for checking the owner_prog_type of a program array map. In some cases bpf(2) can return -EINVAL /after/ the verifier passed and did all the rewrites of the bpf program. The reason that lets us fail at this late stage is that program array maps are incompatible. Allow users to inspect this earlier after they got the map fd through BPF_OBJ_GET command. tc will get support for this. Also, display how much we charged the map with regards to RLIMIT_MEMLOCK.

2016-11-27tipc: fix link statistics counter errorsJon Paul Maloy
In commit e4bf4f76962b ("tipc: simplify packet sequence number handling") we changed the internal representation of the packet sequence number counters from u32 to u16, reflecting what is really sent over the wire. Since then some link statistics counters have been displaying incorrect values, partially because the counters meant to be used as sequence number snapshots are now used as direct counters, stored as u32, and partially because some counter updates are just missing in the code. In this commit we correct this in two ways. First, we base the displayed packet sent/received values on direct counters instead of as previously a calculated difference between current sequence number and a snapshot. Second, we add the missing updates of the counters. This change is compatible with the current netlink API, and requires no changes to the user space tools.

This patch depends on commit d8d263541913 ("ptp: Introduce a high resolution frequency adjustment method.") The gianfar devices offer a frequency resolution of about 0.46 ppb (depends on actual value of tmr_add, for the calculation assumed 0x80000000). This patch lets users of the device benefit from the increased frequency resolution when tuning the clock. Thanks to the rounding the maximum error between the requested frequency and the applied frequency will then be about 0.23 ppb. Tested on a v3.3.8 kernel on a real gianfar device.

Two entries were added to the non-priv ethtool operations switch statement, one in 'net' and one in 'net-next, so simple overlapping changes. Signed-off-by: David S. Miller <davem@davemloft.net>

2016-11-25tipc: resolve connection flow control compatibility problemJon Paul Maloy
In commit 10724cc7bb78 ("tipc: redesign connection-level flow control") we replaced the previous message based flow control with one based on 1k blocks. In order to ensure backwards compatibility the mechanism falls back to using message as base unit when it senses that the peer doesn't support the new algorithm. The default flow control window, i.e., how many units can be sent before the sender blocks and waits for an acknowledge (aka advertisement) is 512. This was tested against the previous version, which uses an acknowledge frequency of on ack per 256 received message, and found to work fine. However, we missed the fact that versions older than Linux 3.15 use an acknowledge frequency of 512, which is exactly the limit where a 4.6+ sender will stop and wait for acknowledge. This would also work fine if it weren't for the fact that if the first sent message on a 4.6+ server side is an empty SYNACK, this one is also is counted as a sent message, while it is not counted as a received message on a legacy 3.15-receiver. This leads to the sender always being one step ahead of the receiver, a scenario causing the sender to block after 512 sent messages, while the receiver only has registered 511 read messages. Hence, the legacy receiver is not trigged to send an acknowledge, with a permanently blocked sender as result. We solve this deadlock by simply allowing the sender to send one more message before it blocks, i.e., by a making minimal change to the condition used for determining connection congestion.

2016-11-25Merge branch 'mlxsw-trap-groups-and-policers'David S. Miller
Jiri Pirko says: ==================== mlxsw: traps, trap groups and policers Nogah says: For a packet to be sent from the HW to the cpu, it needs to be trapped. For a trap to be activate it should be assigned to a trap group. Those trap groups can have policers, to limit the packet rate (the max number of packets that can be sent to the cpu in a time slot, the rest will be discarded) or the data rate (the same, but the count is not by the number of packets but by their total length in bytes). This patchset rearrange the trap setting API, re-write the traps and the trap groups list in spectrum and assign them policers. ==================== Signed-off-by: David S.
