98f91c4 net/mlx5: Fix devlink objects and devlink device unregister sequence Current below problems exists. 1. devlink device is registered by mlx5_load_one(). But it is not unregistered by mlx5_unload_one(). This is incorrect. 2. Above issue leads to, When mlx5 PCI device is removed, currently devlink device is unregistered before devlink ports are unregistered in below ladder diagram. remove_one() mlx5_devlink_unregister() [..] devlink_unregister() <- ports are still registered! mlx5_unload_one() mlx5_unregister_device() mlx5_remove_device() mlx5e_remove() mlx5e_devlink_port_unregister() devlink_port_unregister() 3. Condition checking for registering and unregister device are not symmetric either in these routines. Hence, fix the sequence by having load and unload routines symmetric and in right order. i.e. (a) register devlink device followed by registering devlink ports (b) unregister devlink ports followed by devlink device Do this based on boot and cleanup flags instead of different conditions.

36d45fb net/mlx5e: Fix repeated XSK usage on one channel After an XSK is closed, the relevant structures in the channel are not zeroed. If an XSK is opened the second time on the same channel without recreating channels, the stray values in the structures will lead to incorrect operation of queues, which causes CQE errors, and the new socket doesn't work at all. This patch fixes the issue by explicitly zeroing XSK-related structs in the channel on XSK close. Note that those structs are zeroed on channel creation, and usually a configuration change (XDP program is set) happens on XSK open, which leads to recreating channels, so typical XSK usecases don't suffer from this issue. However, if XSKs are opened and closed on the same channel without removing the XDP program, this bug reproduces.

e0ef26f iavf: fix speed reporting over virtchnl Link speeds are communicated over virtchnl using an enum virtchnl_link_speed. Currently, the highest link speed is 40Gbps which leaves us unable to reflect some speeds that an ice VF is capable of. This causes link speed to be misreported on the iavf driver. Allow for communicating link speeds using Mbps so that the proper speed can be reported for an ice VF. Moving away from the enum allows us to communicate future speed changes without requiring a new enum to be added. In order to support communicating link speeds over virtchnl in Mbps the following functionality was added: - Added u32 link_speed_mbps in the iavf_adapter structure. - Added the macro ADV_LINK_SUPPORT(_a) to determine if the VF driver supports communicating link speeds in Mbps. - Added the function iavf_get_vpe_link_status() to fill the correct link_status in the event_data union based on the ADV_LINK_SUPPORT(_a) macro. - Added the function iavf_set_adapter_link_speed_from_vpe() to determine whether or not to fill the u32 link_speed_mbps or enum virtchnl_link_speed link_speed field in the iavf_adapter structure based on the ADV_LINK_SUPPORT(_a) macro. - Do not free vf_res in iavf_init_get_resources() as vf_res will be accessed in iavf_get_link_ksettings(); memset to 0 instead. This memory is subsequently freed in iavf_remove().

086e907 dt-bindings: Remove more cases of 'allOf' containing a '$ref' Another round of 'allOf' removals that came in this cycle. json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Signed-off-by: Rob Herring <robh@kernel.org> 11 June 2020, 19:50:43 UTC
9798278 tipc: fix NULL pointer dereference in tipc_disc_rcv() When a bearer is enabled, we create a 'tipc_discoverer' object to store the bearer related data along with a timer and a preformatted discovery message buffer for later probing... However, this is only carried after the bearer was set 'up', that left a race condition resulting in kernel panic. It occurs when a discovery message from a peer node is received and processed in bottom half (since the bearer is 'up' already) just before the discoverer object is created but is now accessed in order to update the preformatted buffer (with a new trial address, ...) so leads to the NULL pointer dereference. We solve the problem by simply moving the bearer 'up' setting to later, so make sure everything is ready prior to any message receiving.

This happens after commit 5e9eeccc58f3 ("tipc: fix NULL pointer dereference in streaming") that tried to build at least one buffer even when the message data length is zero... However, it now exposes another bug that the 'mss' can be zero and the 'cpy' will be negative, thus the above kernel WARNING will appear! The zero value of 'mss' is never expected because it means Nagle is not enabled for the socket (actually the socket type was 'SOCK_SEQPACKET'), so the function 'tipc_msg_append()' must not be called at all. But that was in this particular case since the message data length was zero, and the 'send <= maxnagle' check became true. We resolve the issue by explicitly checking if Nagle is enabled for the socket, i.e. 'maxnagle != 0' before calling the 'tipc_msg_append()'. We also reinforce the function to against such a negative values if any.

e3b779d kcsan: Remove 'noinline' from __no_kcsan_or_inline Some compilers incorrectly inline small __no_kcsan functions, which then results in instrumenting the accesses. For this reason, the 'noinline' attribute was added to __no_kcsan_or_inline. All known versions of GCC are affected by this. Supported versions of Clang are unaffected, and never inline a no_sanitize function. However, the attribute 'noinline' in __no_kcsan_or_inline causes unexpected code generation in functions that are __no_kcsan and call a __no_kcsan_or_inline function. In certain situations it is expected that the __no_kcsan_or_inline function is actually inlined by the __no_kcsan function, and *no* calls are emitted. By removing the 'noinline' attribute, give the compiler the ability to inline and generate the expected code in __no_kcsan functions.

d31d4d6 kcsan: Pass option tsan-instrument-read-before-write to Clang Clang (unlike GCC) removes reads before writes with matching addresses in the same basic block. This is an optimization for TSAN, since writes will always cause conflict if the preceding read would have. However, for KCSAN we cannot rely on this option, because we apply several special rules to writes, in particular when the KCSAN_ASSUME_PLAIN_WRITES_ATOMIC option is selected. To avoid missing potential data races, pass the -tsan-instrument-read-before-write option to Clang if it is available [1].

75d75b7 kcsan: Support distinguishing volatile accesses In the kernel, the "volatile" keyword is used in various concurrent contexts, whether in low-level synchronization primitives or for legacy reasons. If supported by the compiler, it will be assumed that aligned volatile accesses up to sizeof(long long) (matching compiletime_assert_rwonce_type()) are atomic. Recent versions of Clang [1] (GCC tentative [2]) can instrument volatile accesses differently. Add the option (required) to enable the instrumentation, and provide the necessary runtime functions. None of the updated compilers are widely available yet (Clang 11 will be the first release to support the feature).

0e1aa5b kcsan: Restrict supported compilers The first version of Clang that supports -tsan-distinguish-volatile will be able to support KCSAN. The first Clang release to do so, will be Clang 11. This is due to satisfying all the following requirements: 1. Never emit calls to __tsan_func_{entry,exit}. 2. __no_kcsan functions should not call anything, not even kcsan_{enable,disable}_current(), when using __{READ,WRITE}_ONCE => Requires leaving them plain! 3. Support atomic_{read,set}*() with KCSAN, which rely on arch_atomic_{read,set}*() using __{READ,WRITE}_ONCE() => Because of #2, rely on Clang 11's -tsan-distinguish-volatile support. We will double-instrument atomic_{read,set}*(), but that's reasonable given it's still lower cost than the data_race() variant due to avoiding 2 extra calls (kcsan_{en,dis}able_current() calls). 4. __always_inline functions inlined into __no_kcsan functions are never instrumented. 5. __always_inline functions inlined into instrumented functions are instrumented. 6. __no_kcsan_or_inline functions may be inlined into __no_kcsan functions => Implies leaving 'noinline' off of __no_kcsan_or_inline. 7. Because of #6, __no_kcsan and __no_kcsan_or_inline functions should never be spuriously inlined into instrumented functions, causing the accesses of the __no_kcsan function to be instrumented. Older versions of Clang do not satisfy #3. The latest GCC currently doesn't support at least #1, #3, and #7.

17168f5 kcsan: Avoid inserting __tsan_func_entry/exit if possible To avoid inserting __tsan_func_{entry,exit}, add option if supported by compiler. Currently only Clang can be told to not emit calls to these functions. It is safe to not emit these, since KCSAN does not rely on them. Note that, if we disable __tsan_func_{entry,exit}(), we need to disable tail-call optimization in sanitized compilation units, as otherwise we may skip frames in the stack trace; in particular when the tail called function is one of the KCSAN's runtime functions, and a report is generated, we might miss the function where the actual access occurred. Since __tsan_func_{entry,exit}() insertion effectively disabled tail-call optimization, there should be no observable change. This was caught and confirmed with kcsan-test & UNWINDER_ORC.

ba838a7 NFS: Fix direct WRITE throughput regression I measured a 50% throughput regression for large direct writes. The observed on-the-wire behavior is that the client sends every NFS WRITE twice: once as an UNSTABLE WRITE plus a COMMIT, and once as a FILE_SYNC WRITE. This is because the nfs_write_match_verf() check in nfs_direct_commit_complete() fails for every WRITE. Buffered writes use nfs_write_completion(), which sets req->wb_verf correctly. Direct writes use nfs_direct_write_completion(), which does not set req->wb_verf at all. This leaves req->wb_verf set to all zeroes for every direct WRITE, and thus nfs_direct_commit_completion() always sets NFS_ODIRECT_RESCHED_WRITES. This fix appears to restore nearly all of the lost performance.

The assumption in vb2_dma_contig_set_max_seg_size() seems to be that dev->dma_parms is always NULL when the driver is probed, and the case where dev->dma_parms has bee initialized by someone else than the driver (by calling vb2_dma_contig_set_max_seg_size) will cause a failure. All the current users of these functions are platform devices, which now always have dma_parms set by the driver core. To fix the issue for v5.7, make vb2_dma_contig_set_max_seg_size() return an error if dma_parms is NULL to be on the safe side, and remove the kfree code from vb2_dma_contig_clear_max_seg_size(). For v5.8 we should remove the two functions and move the dma_set_max_seg_size() calls into the drivers.

However, this has two problems: 1) If there are multiple active streams with different output formats, the hardware will use whichever format was set last for both streams. Similarly, an ioctl() done in an inactive context will wrongly affect other active contexts. 2) The registers are written while the device is not actively streaming. To enable runtime PM tied to the streaming state, all hardware access needs to be moved inside cedrus_device_run(). The call to cedrus_dst_format_set() is now placed just before the codec-specific callback that programs the hardware.

17c3827 media: atomisp: don't set hpll_freq twice with different values The logic which sets the hpll_freq for BYT sets hpll_freq to 1600MHz, but ignores it, and sets it again after reading from-device-specific EFI vars (this time, using a default of 2000MHz). Remove the first set, as this will be overriden anyway. While here, do minor adjustments on comments and on a printk message.

c371af6 media: atomisp: get rid of a detection hack for a BYT Andorid-based tablet There's a hack at the driver that selects a different table for a BYT tablet, which sets the maximum frequency to 320 MHz, instead of 400 MHz. After looking at the Intel Aero Yocto's version from: https://download.01.org/aero/deb/pool/main/l/linux-4.4.76-aero-1.3/ It was noticed that this depends on an Android-specific modprobe parameter, which uses a macro (INTEL_MID_BOARD) from this file: arch/x86/include/asm/spid.h >From the comments there, it looks like this macro parses a variable passed at boot time: cmdline : androidboot.spid=vend:cust:manu:plat:prod:hard The devices in question are identified there as: INTEL_BYT_TABLET_BLK_PRO = 0x0000 INTEL_BYT_TABLET_BLK_ENG = 0x8000 Well, this is something that we don't have upstream. So, without further details about that, we can't really parse it. If we ever end supporting those devices with the upstream driver, this patch can be reverted and the device can be detected via DMI (or maybe via PCI ID?).
