e0e853a Jon Maloy 20 November 2017, 20:43:03 UTC tipc: fix access of released memory When the function tipc_group_filter_msg() finds that a member event indicates that the member is leaving the group, it first deletes the member instance, and then purges the message queue being handled by the call. But the message queue is an aggregated field in the just deleted item, leading the purge call to access freed memory. We fix this by swapping the order of the two actions.

bf4e9f2 Ido Schimmel 21 November 2017, 08:42:21 UTC mlxsw: spectrum: Do not try to create non-existing ports during unsplit On some systems, when we unsplit a port we need to re-create two ports instead. On other systems, only one needs to be re-created. Do not try to create a port if during driver initialization it was assigned a negative module number, which is invalid. This avoids the following error during unsplit: [ 941.012478] mlxsw_spectrum 0000:01:00.0: Port 43: Failed to map module The error is harmless and caused by the fact that a local port is already mapped to module 0.

When cfg80211 is built-in, however, it needs to initialize before drivers (device_initcall/module_init), and thus used to be at subsys_initcall(). I'd moved it to fs_initcall() earlier, where it can remain. However, this is still too early because at that point the key infrastructure hasn't been initialized yet, so X.509 certificates can't be parsed yet. To work around this problem, load the regdb keys only later in a late_initcall(), at which point the necessary infrastructure has been initialized.

After the driver have just started the device reset procedure, device happens to send an asynchronous notification (via AENQ) to the driver than there was a link change (to link-up state). This link change is mapped to a call to netif_carrier_on() which re-activates the Tx queues, violating the assumption of no tx traffic until device reset is completed, as the reset task might still be in the process of queues initialization, leading to an access to uninitialized memory.

020aae3 Roberto Sassu 07 November 2017, 10:37:07 UTC ima: do not update security.ima if appraisal status is not INTEGRITY_PASS Commit b65a9cfc2c38 ("Untangling ima mess, part 2: deal with counters") moved the call of ima_file_check() from may_open() to do_filp_open() at a point where the file descriptor is already opened. This breaks the assumption made by IMA that file descriptors being closed belong to files whose access was granted by ima_file_check(). The consequence is that security.ima and security.evm are updated with good values, regardless of the current appraisal status. For example, if a file does not have security.ima, IMA will create it after opening the file for writing, even if access is denied. Access to the file will be allowed afterwards. Avoid this issue by checking the appraisal status before updating security.ima.

In addition fix EEE advertisement. The current code resets the bits for 100BaseT and 1000BaseT EEE advertisement what is not what we want. I have a little of a hard time to find a proper "Fixes" line as the issue seems to have been there forever (at least it existed already when the driver was moved to the current place in 2011).

ed66dfa Neal Cardwell 18 November 2017, 02:06:14 UTC tcp: when scheduling TLP, time of RTO should account for current ACK Fix the TLP scheduling logic so that when scheduling a TLP probe, we ensure that the estimated time at which an RTO would fire accounts for the fact that ACKs indicating forward progress should push back RTO times. After the following fix: df92c8394e6e ("tcp: fix xmit timer to only be reset if data ACKed/SACKed") we had an unintentional behavior change in the following kind of scenario: suppose the RTT variance has been very low recently. Then suppose we send out a flight of N packets and our RTT is 100ms: t=0: send a flight of N packets t=100ms: receive an ACK for N-1 packets The response before df92c8394e6e that was: -> schedule a TLP for now + RTO_interval The response after df92c8394e6e is: -> schedule a TLP for t=0 + RTO_interval Since RTO_interval = srtt + RTT_variance, this means that we have scheduled a TLP timer at a point in the future that only accounts for RTT_variance. If the RTT_variance term is small, this means that the timer fires soon. Before df92c8394e6e this would not happen, because in that code, when we receive an ACK for a prefix of flight, we did: 1) Near the top of tcp_ack(), switch from TLP timer to RTO at write_queue_head->paket_tx_time + RTO_interval: if (icsk->icsk_pending == ICSK_TIME_LOSS_PROBE) tcp_rearm_rto(sk); 2) In tcp_clean_rtx_queue(), update the RTO to now + RTO_interval: if (flag & FLAG_ACKED) { tcp_rearm_rto(sk); 3) In tcp_ack() after tcp_fastretrans_alert() switch from RTO to TLP at now + RTO_interval: if (icsk->icsk_pending == ICSK_TIME_RETRANS) tcp_schedule_loss_probe(sk); In df92c8394e6e we removed that 3-phase dance, and instead directly set the TLP timer once: we set the TLP timer in cases like this to write_queue_head->packet_tx_time + RTO_interval. So if the RTT variance is small, then this means that this is setting the TLP timer to fire quite soon. This means if the ACK for the tail of the flight takes longer than an RTT to arrive (often due to delayed ACKs), then the TLP timer fires too quickly.

87d11e6 Logan Gunthorpe 03 August 2017, 18:19:53 UTC NTB: switchtec_ntb: Add memory window support The Switchtec hardware has two types of memory windows: LUTs and Direct. The first area in each BAR is for LUT windows and the remaining area is for the direct region. The total number of LUT entries is set by a configuration setting in hardware and they all must be the same size. (This is fixed by switchtec_ntb to be 64K.) switchtec_ntb enables the LUTs only for the first BAR and enables the highest power of two possible. Seeing the LUTs are at the beginning of the BAR, the direct memory window's alignment is affected. Therefore, the maximum direct memory window size can not be greater than the number of LUTs times 64K. The direct window in other BARs will not have this restriction as the LUTs will not be enabled there. LUTs will only be exposed through the NTB API if the use_lut_mw parameter is set. Seeing the Switchtec hardware, by default, configures BARs to be 4G a module parameter is given to limit the size of the advertised memory windows. Higher layers tend to allocate the maximum BAR size and this has a tendency to fail when they try to allocate 4GB of contiguous memory.

This patch converts ntb_transport and ntb_perf to use this function after the link goes up. This simplifies these clients slightly because they no longer have to store the alignment parameters.

The first being a large change that introduces runtime PM support to the clk framework. Now we properly call runtime PM operations on the device providing a clk when the clk is in use. This helps on SoCs where the clks provided by a device need something to be powered on before using the clks, like power domains or regulators. It also helps power those things down when clks aren't in use. The other core change is a devm API addition for clk providers so we can get rid of a bunch of clk driver remove functions that are just doing of_clk_del_provider(). Outside of the core, we have the usual addition of clk drivers and smattering of non-critical fixes to existing drivers. The biggest diff is support for Mediatek MT2712 and MT7622 SoCs, but those patches really just add a bunch of data. By the way, we're trying something new here where we build the tree up with topic branches. We plan to work this into our workflow so that we don't step on each other's toes, and so the fixes branch can be merged on an as-needed basis. Summary: Core: - runtime PM support for clk providers - devm API for of_clk_add_hw_provider() New Drivers: - Mediatek MT2712 and MT7622 - Renesas R-Car V3M SoC Updates: - runtime PM support for Samsung exynos5433/exynos4412 providers - removal of clkdev aliases on Samsung SoCs - convert clk-gpio to use gpio descriptors - various driver cleanups to match kernel coding style - Amlogic Video Processing Unit VPU and VAPB clks - sigma-delta modulation for Allwinner audio PLLs - Allwinner A83t Display clks - support for the second display unit clock on Renesas RZ/G1E - suspend/resume support for Renesas R-Car Gen3 CPG/MSSR - new clock ids for Rockchip rk3188 and rk3368 SoCs - various 'const' markings on clk_ops structures - RPM clk support on Qualcomm MSM8996/MSM8660 SoCs" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (137 commits) clk: stm32h7: fix test of clock config clk: pxa: fix building on older compilers clk: sunxi-ng: a83t: Fix i2c buses bits clk: ti: dra7-atl-clock: fix child-node lookups clk: qcom: common: fix legacy board-clock registration clk: uniphier: fix DAPLL2 clock rate of Pro5 clk: uniphier: fix parent of miodmac clock data clk: hi3798cv200: correct parent mux clock for 'clk_sdio0_ciu' clk: hisilicon: Delete an error message for a failed memory allocation in hisi_register_clkgate_sep() clk: hi3660: fix incorrect uart3 clock freqency clk: kona-setup: Delete error messages for failed memory allocations ARC: clk: fix spelling mistake: "configurarion" -> "configuration" clk: cdce925: remove redundant check for non-null parent_name clk: versatile: Improve sizeof() usage clk: versatile: Delete error messages for failed memory allocations clk: ux500: Improve sizeof() usage clk: ux500: Delete error messages for failed memory allocations clk: spear: Delete error messages for failed memory allocations clk: ti: Delete error messages for failed memory allocations clk: mmp: Adjust checks for NULL pointers ... 18 November 2017, 04:04:24 UTC

If a redirect/pmtu icmp packet comes and the old fnhe is found and all it's members but fnhe_genid will be updated. Then next time when it looks up route and tries to rebind this fnhe to the new dst, the fnhe will be flushed due to fnhe_genid != genid. It causes this redirect/pmtu icmp packet acutally not to be applied. This patch is to also reset fnhe_genid when updating a route cache.

But when updating the exist one, it doesn't do it. It will cause this fnhe never to be expired. Paolo already noticed it before, in Jianlin's test case, it became even worse: When ip route flush cache, the old fnhe is not to be removed, but only clean it's members. When redirect comes again, this fnhe will be found and updated, but never be expired due to fnhe_expires not being set. So fix it by simply updating fnhe_expires even it's for redirect.

ecca8f8 Xin Long 17 November 2017, 06:11:11 UTC sctp: set frag_point in sctp_setsockopt_maxseg correctly Now in sctp_setsockopt_maxseg user_frag or frag_point can be set with val >= 8 and val <= SCTP_MAX_CHUNK_LEN. But both checks are incorrect. val >= 8 means frag_point can even be less than SCTP_DEFAULT_MINSEGMENT. Then in sctp_datamsg_from_user(), when it's value is greater than cookie echo len and trying to bundle with cookie echo chunk, the first_len will overflow. The worse case is when it's value is equal as cookie echo len, first_len becomes 0, it will go into a dead loop for fragment later on. In Hangbin syzkaller testing env, oom was even triggered due to consecutive memory allocation in that loop. Besides, SCTP_MAX_CHUNK_LEN is the max size of the whole chunk, it should deduct the data header for frag_point or user_frag check. This patch does a proper check with SCTP_DEFAULT_MINSEGMENT subtracting the sctphdr and datahdr, SCTP_MAX_CHUNK_LEN subtracting datahdr when setting frag_point via sockopt. It also improves sctp_setsockopt_maxseg codes.

15df03c Davidlohr Bueso 17 November 2017, 23:31:18 UTC sysvipc: make get_maxid O(1) again For a custom microbenchmark on a 3.30GHz Xeon SandyBridge, which calls IPC_STAT over and over, it was calculated that, on avg the cost of ipc_get_maxid() for increasing amounts of keys was: 10 keys: ~900 cycles 100 keys: ~15000 cycles 1000 keys: ~150000 cycles 10000 keys: ~2100000 cycles This is unsurprising as maxid is currently O(n). By having the max_id available in O(1) we save all those cycles for each semctl(_STAT) command, the idr_find can be expensive -- which some real (customer) workloads actually poll on. Note that this used to be the case, until commit 7ca7e564e04 ("ipc: store ipcs into IDRs"). The cost is the extra idr_find when doing RMIDs, but we simply go backwards, and should not take too many iterations to find the new value.

b8fd998 Davidlohr Bueso 17 November 2017, 23:31:08 UTC sysvipc: unteach ids->next_id for !CHECKPOINT_RESTORE Patch series "sysvipc: ipc-key management improvements". Here are a few improvements I spotted while eyeballing Guillaume's rhashtable implementation for ipc keys. The first and fourth patches are the interesting ones, the middle two are trivial. This patch (of 4): The next_id object-allocation functionality was introduced in commit 03f595668017 ("ipc: add sysctl to specify desired next object id"). Given that these new entries are _only_ exported under the CONFIG_CHECKPOINT_RESTORE option, there is no point for the common case to even know about ->next_id. As such rewrite ipc_buildid() such that it can do away with the field as well as unnecessary branches when adding a new identifier. The end result also better differentiates both cases, so the code ends up being cleaner; albeit the small duplications regarding the default case.

ded97d2 Victor Chibotaru 17 November 2017, 23:30:46 UTC kcov: support comparison operands collection Enables kcov to collect comparison operands from instrumented code. This is done by using Clang's -fsanitize=trace-cmp instrumentation (currently not available for GCC). The comparison operands help a lot in fuzz testing. E.g. they are used in Syzkaller to cover the interiors of conditional statements with way less attempts and thus make previously unreachable code reachable. To allow separate collection of coverage and comparison operands two different work modes are implemented. Mode selection is now done via a KCOV_ENABLE ioctl call with corresponding argument value.

4efb442 Borislav Petkov 17 November 2017, 23:30:38 UTC kernel/panic.c: add TAINT_AUX This is the gist of a patch which we've been forward-porting in our kernels for a long time now and it probably would make a good sense to have such TAINT_AUX flag upstream which can be used by each distro etc, how they see fit. This way, we won't need to forward-port a distro-only version indefinitely. Add an auxiliary taint flag to be used by distros and others. This obviates the need to forward-port whatever internal solutions people have in favor of a single flag which they can map arbitrarily to a definition of their pleasing. The "X" mnemonic could also mean eXternal, which would be taint from a distro or something else but not the upstream kernel. We will use it to mark modules for which we don't provide support. I.e., a really eXternal module.
