2019-06-15tcp: tcp_fragment() should apply sane memory limitsEric Dumazet1-0/+1
Jonathan Looney reported that a malicious peer can force a sender to fragment its retransmit queue into tiny skbs, inflating memory usage and/or overflow 32bit counters. TCP allows an application to queue up to sk_sndbuf bytes, so we need to give some allowance for non malicious splitting of retransmit queue. A new SNMP counter is added to monitor how many times TCP did not allow to split an skb if the allowance was exceeded. Note that this counter might increase in the case applications use SO_SNDBUF socket option to lower sk_sndbuf.

Previously, the BPF_FIB_LOOKUP_{DIRECT,OUTPUT} flags in the BPF UAPI were defined with the help of BIT macro. This had the following issues: - In order to use any of the flags, a user was required to depend on <linux/bits.h>. - No other flag in bpf.h uses the macro, so it seems that an unwritten convention is to use (1 << (nr)) to define BPF-related flags.

2019-06-06bpf: fix unconnected udp hooksDaniel Borkmann1-0/+2
Intention of cgroup bind/connect/sendmsg BPF hooks is to act transparently to applications as also stated in original motivation in 7828f20e3779 ("Merge branch 'bpf-cgroup-bind-connect'"). When recently integrating the latter two hooks into Cilium to enable host based load-balancing with Kubernetes, I ran into the issue that pods couldn't start up as DNS got broken. Kubernetes typically sets up DNS as a service and is thus subject to load-balancing. Upon further debugging, it turns out that the cgroupv2 sendmsg BPF hooks API is currently insufficient and thus not usable as-is for standard applications shipped with most distros. To break down the issue we ran into with a simple example: # cat /etc/resolv.conf nameserver 147.75.207.207 nameserver 147.75.207.208 For the purpose of a simple test, we set up above IPs as service IPs and transparently redirect traffic to a different DNS backend server for that node: # cilium service list ID Frontend Backend 1 147.75.207.207:53 1 => 8.8.8.8:53 2 147.75.207.208:53 1 => 8.8.8.8:53 The attached BPF program is basically selecting one of the backends if the service IP/port matches on the cgroup hook. DNS breaks here, because the hooks are not transparent enough to applications which have built-in msg_name address checks: # nslookup 1.1.1.1 ;; reply from unexpected source: 8.8.8.8#53, expected 147.75.207.207#53 ;; reply from unexpected source: 8.8.8.8#53, expected 147.75.207.208#53 ;; reply from unexpected source: 8.8.8.8#53, expected 147.75.207.207#53 [...] ;; connection timed out; no servers could be reached # dig 1.1.1.1 ;; reply from unexpected source: 8.8.8.8#53, expected 147.75.207.207#53 ;; reply from unexpected source: 8.8.8.8#53, expected 147.75.207.208#53 ;; reply from unexpected source: 8.8.8.8#53, expected 147.75.207.207#53 [...] ; <<>> DiG 9.11.3-1ubuntu1.7-Ubuntu <<>> 1.1.1.1 ;; global options: +cmd ;; connection timed out; no servers could be reached For comparison, if none of the service IPs is used, and we tell nslookup to use 8.8.8.8 directly it works just fine, of course: # nslookup 1.1.1.1 8.8.8.8 1.1.1.1.in-addr.arpa name = one.one.one.one. In order to fix this and thus act more transparent to the application, this needs reverse translation on recvmsg() side. A minimal fix for this API is to add similar recvmsg() hooks behind the BPF cgroups static key such that the program can track state and replace the current sockaddr_in{,6} with the original service IP. From BPF side, this basically tracks the service tuple plus socket cookie in an LRU map where the reverse NAT can then be retrieved via map value as one example. Side-note: the BPF cgroups static key should be converted to a per-hook static key in future. Same example after this fix: # cilium service list ID Frontend Backend 1 147.75.207.207:53 1 => 8.8.8.8:53 2 147.75.207.208:53 1 => 8.8.8.8:53 Lookups work fine now: # nslookup 1.1.1.1 1.1.1.1.in-addr.arpa name = one.one.one.one. Authoritative answers can be found from: # dig 1.1.1.1 ; <<>> DiG 9.11.3-1ubuntu1.7-Ubuntu <<>> 1.1.1.1 ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 51550 ;; flags: qr rd ra ad; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 512 ;; QUESTION SECTION: ;1.1.1.1.

(67) [...] In order to be flexible and to have same semantics as in sendmsg BPF programs, we only allow return codes in [1,1] range. In the sendmsg case the program is called if msg->msg_name is present which can be the case in both, connected and unconnected UDP. The former only relies on the sockaddr_in{,6} passed via connect(2) if passed msg->msg_name was NULL. Therefore, on recvmsg side, we act in similar way to call into the BPF program whenever a non-NULL msg->msg_name was passed independent of sk->sk_state being TCP_ESTABLISHED or not. Note that for TCP case, the msg->msg_name is ignored in the regular recvmsg path and therefore not relevant. For the case of ip{,v6}_recv_error() paths, picked up via MSG_ERRQUEUE, the hook is not called. This is intentional as it aligns with the same semantics as in case of TCP cgroup BPF hooks right now. This might be better addressed in future through a different bpf_attach_type such that this case can be distinguished from the regular recvmsg paths, for example.

In the FOPEN_DIRECT_IO case the write path doesn't call file_remove_privs() and that means setuid bit is not cleared if unpriviliged user writes to a file with setuid bit set. pjdfstest chmod test 12.t tests this and fails. Fix this by adding a flag to the FUSE_WRITE message that requests clearing privileges on the given file. This needs This better than just calling fuse_remove_privs(), because the attributes may not be up to date, so in that case a write may miss clearing the privileges.

2019-05-24uapi/habanalabs: add opcode for enable/disable device debug modeOded Gabbay1-2/+20
This patch defines a new opcode in the DEBUG IOCTL that is used by the user to notify the driver when the user wants to start or stop using the debug and profile infrastructure of the device. i.e. set the device to debug mode or to non-debug mode. There are a couple of restrictions that this new opcode introduces: 1. The user can't configure the debug/profiling infrastructure before he sets the device to debug mode, by using this new opcode. 2. The user can't set the device to debug mode unless he is the only user that is currently using (has an open FD) the device. 3. Other users can't use the device (open a new FD) in case an existing user has set the device into debug mode. These restrictions are needed because the debug and profiling infrastructure is a shared component in the ASIC and therefore, can't be used while multiple users are working on the device. Because the driver currently does NOT support multiple users, the implementation of the restrictions is not required at this point. However, the interface definition is needed in order to avoid changing the user API later on. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>

2019-05-20tipc: Avoid copying bytes beyond the supplied dataChris Packham1-3/+7
TLV_SET is called with a data pointer and a len parameter that tells us how many bytes are pointed to by data. When invoking memcpy() we need to careful to only copy len bytes. Previously we would copy TLV_LENGTH(len) bytes which would copy an extra 4 bytes past the end of the data pointer which newer GCC versions complain about. In file included from test.c:17: In function 'TLV_SET', inlined from 'test' at test.c:186:5: /usr/include/linux/tipc_config.h:317:3: warning: 'memcpy' forming offset [33, 36] is out of the bounds [0, 32] of object 'bearer_name' with type 'char[32]' [-Warray-bounds] memcpy(TLV_DATA(tlv_ptr), data, tlv_len); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ test.c: In function 'test': test.c::161:10: note: 'bearer_name' declared here char bearer_name[TIPC_MAX_BEARER_NAME]; ^~~~~~~~~~~ We still want to ensure any padding bytes at the end are initialised, do this with a explicit memset() rather than copy bytes past the end of data.

2019-05-14fs/sync.c: sync_file_range(2) may use WB_SYNC_ALL writebackAmir Goldstein1-0/+3
23d0127096cb ("fs/sync.c: make sync_file_range(2) use WB_SYNC_NONE writeback") claims that sync_file_range(2) syscall was "created for userspace to be able to issue background writeout and so waiting for in-flight IO is undesirable there" and changes the writeback (back) to WB_SYNC_NONE. This claim is only partially true. It is true for users that use the flag SYNC_FILE_RANGE_WRITE by itself, as does PostgreSQL, the user that was the reason for changing to WB_SYNC_NONE writeback. However, that claim is not true for users that use that flag combination SYNC_FILE_RANGE_{WAIT_BEFORE|WRITE|_WAIT_AFTER}. Those users explicitly requested to wait for in-flight IO as well as to writeback of dirty pages. Re-brand that flag combination as SYNC_FILE_RANGE_WRITE_AND_WAIT and use WB_SYNC_ALL writeback to perform the full range sync request.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "The most significant changes at this cycle are the Sound Open Firmware support from Intel for the common DSP framework along with its support for Intel platforms. It's a door opened to a real "free" firmware (in the sense of FOSS), and other parties show interests in it. In addition to SOF, we've got a bunch of updates and fixes as usual. Some highlights are below. ALSA core: - Cleanups and fixes in ALSA timer code to cover some races spotted by syzkaller - Cleanups and fixes in ALSA sequencer code to cover some races, again unsurprisingly, spotted by syzkaller - Optimize the common page allocation helper with alloc_pages_exact() ASoC: - Add SOF core support, as well as Intel SOF platform support - Generic card driver improvements: support for MCLK/sample rate ratio and pin switches - A big set of improvements to TLV320AIC32x4 drivers - New drivers for Freescale audio mixers, several Intel machines, several Mediatek machines, Meson G12A, Spreadtrum compressed audio and DMA devices HD-audio: - A few Realtek codec fixes for reducing pop noises - Quirks for Chromebooks - Workaround for faulty connection report on AMD/Nvidia HDMI Others: - A quirk for Focusrite Scarlett Solo USB-audio - Add support for MOTU 8pre FireWire - 24bit sample format support in aloop - GUS patch format support (finally, over a decade) in native emux synth code" * tag 'sound-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (375 commits) ASoC: SOF: Fix unused variable warnings ALSA: line6: toneport: Fix broken usage of timer for delayed execution ALSA: aica: Fix a long-time build breakage ALSA: hda/realtek - Support low power consumption for ALC256 ASoC: stm32: i2s: update pcm hardware constraints ASoC: codec: hdac_hdmi: no checking monitor in hw_params ASoC: mediatek: mt6358: save PGA for mixer control ASoC: mediatek: mt6358: save output volume for mixer controls ASoC: mediatek: mt6358: initialize setting when ramping volume ASoC: SOF: core: fix undefined nocodec reference ASoC: SOF: xtensa: fix undefined references ASoC: SOF: Propagate sof_get_ctrl_copy_params() error properly ALSA: hdea/realtek - Headset fixup for System76 Gazelle (gaze14) ALSA: hda/intel: add CometLake PCI IDs ALSA: hda/realtek - Support low power consumption for ALC295 ASoC: rockchip: Fix an uninitialized variable compile warning ASoC: SOF: Fix a compile warning with CONFIG_PCI=n ASoC: da7219: Fix a compile warning at CONFIG_COMMON_CLK=n ASoC: sound/soc/sof/: fix kconfig dependency warning ASoC: stm32: spdifrx: change trace level on iec control ...

Pull drm updates from Dave Airlie: "This has two exciting community drivers for ARM Mali accelerators. Since ARM has never been open source friendly on the GPU side of the house, the community has had to create open source drivers for the Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx series. Well done to all involved and hopefully this will help ARM head in the right direction. There is also now the ability if you don't have any of the legacy drivers enabled (pre-KMS) to remove all the pre-KMS support code from the core drm, this saves 10% or so in codesize on my machine. i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo moves out of staging. There are also some rcar-du patches which crossover with media tree but all should be acked by Mauro.
