2019-07-16net: ethernet: mediatek: mtk_eth_soc: Add of_node_put() before gotoNishka Dasgupta1-1/+3
Each iteration of for_each_child_of_node puts the previous node, but in the case of a goto from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the goto. Issue found with Coccinelle. Signed-off-by: Nishka Dasgupta <nishkadg.linux@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Each iteration of for_each_available_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the return in two places. Issue found with Coccinelle. Signed-off-by: Nishka Dasgupta <nishkadg.linux@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-07-16net: ethernet: ti: cpsw: Add of_node_put() before return and breakNishka Dasgupta1-8/+18
Each iteration of for_each_available_child_of_node puts the previous node, but in the case of a return or break from the middle of the loop, there is no put, thus causing a memory leak. Hence, for function cpsw_probe_dt, create an extra label err_node_put that puts the last used node and returns ret; modify the return statements in the loop to save the return value in ret and goto this new label. For function cpsw_remove_dt, add an of_node_put before the break. Issue found with Coccinelle. Signed-off-by: Nishka Dasgupta <nishkadg.linux@gmail.com> Signed-off-by: David S.

2019-07-15net/mlx5e: Allow dissector meta key in tc flowerVlad Buslov1-1/+2
Recently, fl_flow_key->indev_ifindex int field was refactored into flow_dissector_key_meta field. With this, flower classifier also sets FLOW_DISSECTOR_KEY_META flow dissector key. However, mlx5 flower dissector validation code rejects filters that use flow dissector keys that are not supported. Add FLOW_DISSECTOR_KEY_META to the list of allowed dissector keys in __parse_cls_flower() to prevent following error when offloading flower classifier to mlx5: Error: mlx5_core: Unsupported key.

2019-07-15net/mlx5e: Rely on filter_dev instead of dissector keys for tunnelsVlad Buslov1-5/+1
Currently, tunnel attributes are parsed and inner header matching is used only when flow dissector specifies match on some of the supported encapsulation fields. When user tries to offload tc filter that doesn't match any encapsulation fields on tunnel device, mlx5 tc layer incorrectly sets to match packet header keys on encap header (outer header) and firmware rejects the rule with syndrome 0x7e1579 when creating new flow group. Change __parse_cls_flower() to determine whether tunnel is used based on fitler_dev tunnel info, instead of determining it indirectly by checking flow dissector enc keys.

This was necessary for the ST Microelectronics STMFX expander and need to be tested on other systems as well: it makes sense to make this default in the long run. Right now it is opt-in per driver. - Drive strength can be specified in microamps.

Driver improvements: - The Bitmain BM1880 driver now supports pin config in addition to muxing. - The Qualcomm drivers can now reserve some GPIOs as taken aside and not usable for users. This is used in ACPI systems to take out some GPIO lines used by the BIOS so that noone else (neither kernel nor userspace) will play with them by mistake and crash the machine. - A slew of refurbishing around the Aspeed drivers (board management controllers for servers) in preparation for the new Aspeed AST2600 SoC. - A slew of improvements over the SH PFC drivers as usual. - Misc cleanups and fixes" * tag 'pinctrl-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (106 commits) pinctrl: aspeed: Strip moved macros and structs from private header pinctrl: aspeed: Fix missed include pinctrl: baytrail: Use GENMASK() consistently pinctrl: baytrail: Re-use data structures from pinctrl-intel.h pinctrl: baytrail: Use defined macro instead of magic in byt_get_gpio_mux() pinctrl: qcom: Add SM8150 pinctrl driver dt-bindings: pinctrl: qcom: Add SM8150 pinctrl binding dt-bindings: pinctrl: qcom: Document missing gpio nodes pinctrl: aspeed: Add implementation-related documentation pinctrl: aspeed: Split out pinmux from general pinctrl pinctrl: aspeed: Clarify comment about strapping W1C pinctrl: aspeed: Correct comment that is no longer true MAINTAINERS: Add entry for ASPEED pinctrl drivers dt-bindings: pinctrl: aspeed: Convert AST2500 bindings to json-schema dt-bindings: pinctrl: aspeed: Convert AST2400 bindings to json-schema dt-bindings: pinctrl: aspeed: Split bindings document in two pinctrl: qcom: Add irq_enable callback for msm gpio pinctrl: madera: Fixup SPDX headers pinctrl: qcom: sdm845: Fix CONFIG preprocessor guard pinctrl: tegra: Add bitmask support for parked bits ...

2019-07-12ppp: mppe: Revert "ppp: mppe: Add softdep to arc4"Eric Biggers1-1/+0
Commit 0e5a610b5ca5 ("ppp: mppe: switch to RC4 library interface"), which was merged through the crypto tree for v5.3, changed ppp_mppe.c to use the new arc4_crypt() library function rather than access RC4 through the dynamic crypto_skcipher API. Meanwhile commit aad1dcc4f011 ("ppp: mppe: Add softdep to arc4") was merged through the net tree and added a module soft-dependency on "arc4". The latter commit no longer makes sense because the code now uses the "libarc4" module rather than "arc4", and also due to the direct use of arc4_crypt(), no module soft-dependency is required.

The cudbg_collect_mem_region() and cudbg_read_fw_mem() both use several hundred kilobytes of kernel stack space. One gets inlined into the other, which causes the stack usage to be combined beyond the warning limit when building with clang: drivers/net/ethernet/chelsio/cxgb4/cudbg_lib.c:1057:12: error: stack frame size of 1244 bytes in function 'cudbg_collect_mem_region' [-Werror,-Wframe-larger-than=] Restructuring cudbg_collect_mem_region() lets clang do the same optimization that gcc does and reuse the stack slots as it can see that the large variables are never used together.

2019-07-12nfp: flower: ensure ip protocol is specified for L4 matchesJohn Hurley1-9/+6
Flower rules on the NFP firmware are able to match on an IP protocol field. When parsing rules in the driver, unknown IP protocols are only rejected when further matches are to be carried out on layer 4 fields, as the firmware will not be able to extract such fields from packets. L4 protocol dissectors such as FLOW_DISSECTOR_KEY_PORTS are only parsed if an IP protocol is specified. This leaves a loophole whereby a rule that attempts to match on transport layer information such as port numbers but does not explicitly give an IP protocol type can be incorrectly offloaded (in this case with wildcard port numbers matches). Fix this by rejecting the offload of flows that attempt to match on L4 information, not only when matching on an unknown IP protocol type, but also when the protocol is wildcarded.

2019-07-12nfp: flower: fix ethernet check on match fieldsJohn Hurley1-8/+5
NFP firmware does not explicitly match on an ethernet type field. Rather, each rule has a bitmask of match fields that can be used to infer the ethernet type. Currently, if a flower rule contains an unknown ethernet type, a check is carried out for matches on other fields of the packet. If matches on layer 3 or 4 are found, then the offload is rejected as firmware will not be able to extract these fields from a packet with an ethernet type it does not currently understand. However, if a rule contains an unknown ethernet type without any L3 (or above) matches then this will effectively be offloaded as a rule with a wildcarded ethertype. This can lead to misclassifications on the firmware. Fix this issue by rejecting all flower rules that specify a match on an unknown ethernet type. Further ensure correct offloads by moving the 'L3 and above' check to any rule that does not specify an ethernet type and rejecting rules with further matches. This means that we can still offload rules with a wildcarded ethertype if they only match on L2 fields but will prevent rules which match on further fields that we cannot be sure if the firmware will be able to extract.

2019-07-12mm: security: introduce init_on_alloc=1 and init_on_free=1 boot optionsAlexander Potapenko1-1/+1
Patch series "add init_on_alloc/init_on_free boot options", v10. Provide init_on_alloc and init_on_free boot options. These are aimed at preventing possible information leaks and making the control-flow bugs that depend on uninitialized values more deterministic. Enabling either of the options guarantees that the memory returned by the page allocator and SL[AU]B is initialized with zeroes. SLOB allocator isn't supported at the moment, as its emulation of kmem caches complicates handling of SLAB_TYPESAFE_BY_RCU caches correctly. Enabling init_on_free also guarantees that pages and heap objects are initialized right after they're freed, so it won't be possible to access stale data by using a dangling pointer. As suggested by Michal Hocko, right now we don't let the heap users to disable initialization for certain allocations. There's not enough evidence that doing so can speed up real-life cases, and introducing ways to opt-out may result in things going out of control. This patch (of 2): The new options are needed to prevent possible information leaks and make control-flow bugs that depend on uninitialized values more deterministic. This is expected to be on-by-default on Android and Chrome OS. And it gives the opportunity for anyone else to use it under distros too via the boot args. (The init_on_free feature is regularly requested by folks where memory forensics is included in their threat models.) init_on_alloc=1 makes the kernel initialize newly allocated pages and heap objects with zeroes. Initialization is done at allocation time at the places where checks for __GFP_ZERO are performed. init_on_free=1 makes the kernel initialize freed pages and heap objects with zeroes upon their deletion. This helps to ensure sensitive data doesn't leak via use-after-free accesses. Both init_on_alloc=1 and init_on_free=1 guarantee that the allocator returns zeroed memory. The two exceptions are slab caches with constructors and SLAB_TYPESAFE_BY_RCU flag. Those are never zero-initialized to preserve their semantics. Both init_on_alloc and init_on_free default to zero, but those defaults can be overridden with CONFIG_INIT_ON_ALLOC_DEFAULT_ON and CONFIG_INIT_ON_FREE_DEFAULT_ON. If either SLUB poisoning or page poisoning is enabled, those options take precedence over init_on_alloc and init_on_free: initialization is only applied to unpoisoned allocations. Slowdown for the new features compared to init_on_free=0, init_on_alloc=0: hackbench, init_on_free=1: +7.62% sys time (st.err 0.74%) hackbench, init_on_alloc=1: +7.75% sys time (st.err 2.14%) Linux build with -j12, init_on_free=1: +8.38% wall time (st.err 0.39%) Linux build with -j12, init_on_free=1: +24.42% sys time (st.err 0.52%) Linux build with -j12, init_on_alloc=1: -0.13% wall time (st.err 0.42%) Linux build with -j12, init_on_alloc=1: +0.57% sys time (st.err 0.40%) The slowdown for init_on_free=0, init_on_alloc=0 compared to the baseline is within the standard error. The new features are also going to pave the way for hardware memory tagging (e.g. arm64's MTE), which will require both on_alloc and on_free hooks to set the tags for heap objects. With MTE, tagging will have the same cost as memory initialization. Although init_on_free is rather costly, there are paranoid use-cases where in-memory data lifetime is desired to be minimized. There are various arguments for/against the realism of the associated threat models, but given that we'll need the infrastructure for MTE anyway, and there are people who want wipe-on-free behavior no matter what the performance cost, it seems reasonable to include it in this series.

2019-07-12dm bufio: fix deadlock with loop deviceJunxiao Bi1-3/+1
When thin-volume is built on loop device, if available memory is low, the following deadlock can be triggered: One process P1 allocates memory with GFP_FS flag, direct alloc fails, memory reclaim invokes memory shrinker in dm_bufio, dm_bufio_shrink_scan() runs, mutex dm_bufio_client->lock is acquired, then P1 waits for dm_buffer IO to complete in __try_evict_buffer(). But this IO may never complete if issued to an underlying loop device that forwards it using direct-IO, which allocates memory using GFP_KERNEL (see: do_blockdev_direct_IO()). If allocation fails, memory reclaim will invoke memory shrinker in dm_bufio, dm_bufio_shrink_scan() will be invoked, and since the mutex is already held by P1 the loop thread will hang, and IO will never complete. Resulting in ABBA deadlock. Cc: stable@vger.kernel.org Signed-off-by: Junxiao Bi <junxiao.bi@oracle.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
2019-07-12dm snapshot: add optional discard support featuresMike Snitzer1-21/+165
discard_zeroes_cow - a discard issued to the snapshot device that maps to entire chunks to will zero the corresponding exception(s) in the snapshot's exception store. discard_passdown_origin - a discard to the snapshot device is passed down to the snapshot-origin's underlying device. This doesn't cause copy-out to the snapshot exception store because the snapshot-origin target is bypassed. The discard_passdown_origin feature depends on the discard_zeroes_cow feature being enabled. When these 2 features are enabled they allow a temporarily read-only device that has completely exhausted its free space to recover space. To do so dm-snapshot provides temporary buffer to accommodate writes that the temporarily read-only device cannot handle yet. Once the upper layer frees space (e.g. fstrim to XFS) the discards issued to the dm-snapshot target will be issued to underlying read-only device whose free space was exhausted. In addition those discards will also cause zeroes to be written to the snapshot exception store if corresponding exceptions exist. If the underlying origin device provides deduplication for zero blocks then if/when the snapshot is merged backed to the origin those blocks will become unused. Once the origin has gained adequate space, merging the snapshot back to the thinly provisioned device will permit continued use of that device without the temporary space provided by the snapshot.
