2021-03-23net: set initial device refcount to 1Eric Dumazet1-0/+1
When adding CONFIG_PCPU_DEV_REFCNT, I forgot that the initial net device refcount was 0. When CONFIG_PCPU_DEV_REFCNT is not set, this means the first dev_hold() triggers an illegal refcount operation (addition on 0) refcount_t: addition on 0; use-after-free. WARNING: CPU: 0 PID: 1 at lib/refcount.c:25 refcount_warn_saturate+0x128/0x1a4 Fix is to change initial (and final) refcount to be 1. Also add a missing kerneldoc piece, as reported by Stephen Rothwell.

git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue Tony Nguyen says: ==================== 100GbE Intel Wired LAN Driver Updates 2021-03-22 This series contains updates to ice and iavf drivers. Haiyue Wang says: The Intel E810 Series supports a programmable pipeline for a domain specific protocols classification, for example GTP by Dynamic Device Personalization (DDP) profile. The E810 PF has introduced flex-bytes support by ethtool user-def option allowing for packet deeper matching based on an offset and value for DDP usage. For making VF also benefit from this flexible protocol classification, some new virtchnl messages are defined and handled by PF, so VF can query this new flow director capability, and use ethtool with extending the user-def option to configure Rx flow classification. The new user-def 0xAAAABBBBCCCCDDDD: BBBB is the 2 byte pattern while AAAA corresponds to its offset in the packet. Similarly DDDD is the 2 byte pattern with CCCC being the corresponding offset. The offset ranges from 0x0 to 0x1F7 (up to 504 bytes into the packet). The offset starts from the beginning of the packet. This feature can be used to allow customers to set flow director rules for protocols headers that are beyond standard ones supported by ethtool (e.g. PFCP or GTP-U). Like for matching GTP-U's TEID value 0x10203040: ethtool -N ens787f0v0 flow-type udp4 dst-port 2152 \ user-def 0x002e102000303040 action 13 ==================== Signed-off-by: David S.

2021-03-22net: move the ptype_all and ptype_base declarations to include/linux/netdevice.hVladimir Oltean1-0/+3
ptype_all and ptype_base are declared in net/core/dev.c as non-static, because they are used by net-procfs.c too. However, a "make W=1" build complains that there was no previous declaration of ptype_all and ptype_base in a header file, so this way of declaring things constitutes a violation of coding style. Let's move the extern declarations of ptype_all and ptype_base to the linux/netdevice.h file, which is included by net-procfs.c too.

2021-03-22netdev: add netdev_queue_set_dql_min_limit()Vincent Mailhol1-0/+18
Add a function to set the dynamic queue limit minimum value. Some specific drivers might have legitimate reasons to configure dql.min_limit to a given value. Typically, this is the case when the PDU of the protocol is smaller than the packet size to used to carry those frames to the device. Concrete example: a CAN (Control Area Network) device with an USB 2.0 interface. The PDU of classical CAN protocol are roughly 16 bytes but the USB packet size (which is used to carry the CAN frames to the device) might be up to 512 bytes. Wen small traffic burst occurs, BQL algorithm is not able to immediately adjust and this would result in having to send many small USB packets (i.e packet of 16 bytes for each CAN frame). Filling up the USB packet with CAN frames is relatively fast (small latency issue) but the gain of not having to send several small USB packets is huge (big throughput increase). In this case, forcing dql.min_limit to a given value that would allow to stuff the USB packet is always a win. This function is to be used by network drivers which are able to prove through a rationale and through empirical tests on several environment (with other applications, heavy context switching, virtualization...), that they constantly reach better performances with a specific predefined dql.min_limit value with no noticeable latency impact.

2021-03-22lsm: separate security_task_getsecid() into subjective and objective variantsPaul Moore4-7/+22
Of the three LSMs that implement the security_task_getsecid() LSM hook, all three LSMs provide the task's objective security credentials. This turns out to be unfortunate as most of the hook's callers seem to expect the task's subjective credentials, although a small handful of callers do correctly expect the objective credentials. This patch is the first step towards fixing the problem: it splits the existing security_task_getsecid() hook into two variants, one for the subjective creds, one for the objective creds. void security_task_getsecid_subj(struct task_struct *p, u32 *secid); void security_task_getsecid_obj(struct task_struct *p, u32 *secid); While this patch does fix all of the callers to use the correct variant, in order to keep this patch focused on the callers and to ease review, the LSMs continue to use the same implementation for both hooks. The net effect is that this patch should not change the behavior of the kernel in any way, it will be up to the latter LSM specific patches in this series to change the hook implementations and return the correct credentials.

2021-03-22ice: Enable FDIR Configure for AVFQi Zhang1-0/+278
The virtual channel is going to be extended to support FDIR and RSS configure from AVF. New data structures and OP codes will be added, the patch enable the FDIR part. To support above advanced AVF feature, we need to figure out what kind of data structure should be passed from VF to PF to describe an FDIR rule or RSS config rule. The common part of the requirement is we need a data structure to represent the input set selection of a rule's hash key. An input set selection is a group of fields be selected from one or more network protocol layers that could be identified as a specific flow. For example, select dst IP address from an IPv4 header combined with dst port from the TCP header as the input set for an IPv4/TCP flow. The patch adds a new data structure virtchnl_proto_hdrs to abstract a network protocol headers group which is composed of layers of network protocol header(virtchnl_proto_hdr). A protocol header contains a 32 bits mask (field_selector) to describe which fields are selected as input sets, as well as a header type (enum virtchnl_proto_hdr_type). Each bit is mapped to a field in enum virtchnl_proto_hdr_field guided by its header type. +------------+-----------+------------------------------+ | | Proto Hdr | Header Type A | | | +------------------------------+ | | | BIT 31 | ... | BIT 1 | BIT 0 | | |-----------+------------------------------+ |Proto Hdrs | Proto Hdr | Header Type B | | | +------------------------------+ | | | BIT 31 | ... | BIT 1 | BIT 0 | | |-----------+------------------------------+ | | Proto Hdr | Header Type C | | | +------------------------------+ | | | BIT 31 | ... | BIT 1 | BIT 0 | | |-----------+------------------------------+ | | .... | +-------------------------------------------------------+ All fields in enum virtchnl_proto_hdr_fields are grouped with header type and the value of the first field of a header type is always 32 aligned. enum proto_hdr_type { header_type_A = 0; header_type_B = 1; .... } enum proto_hdr_field { /* header type A */ header_A_field_0 = 0, header_A_field_1 = 1, header_A_field_2 = 2, header_A_field_3 = 3, /* header type B */ header_B_field_0 = 32, // = header_type_B << 5 header_B_field_0 = 33, header_B_field_0 = 34 header_B_field_0 = 35, .... }; So we have: proto_hdr_type = proto_hdr_field / 32 bit offset = proto_hdr_field % 32 To simply the protocol header's operations, couple help macros are added. For example, to select src IP and dst port as input set for an IPv4/UDP flow. we have: struct virtchnl_proto_hdr hdr[2]; VIRTCHNL_SET_PROTO_HDR_TYPE(&hdr[0], IPV4) VIRTCHNL_ADD_PROTO_HDR_FIELD(&hdr[0], IPV4, SRC) VIRTCHNL_SET_PROTO_HDR_TYPE(&hdr[1], UDP) VIRTCHNL_ADD_PROTO_HDR_FIELD(&hdr[1], UDP, DST) The byte array is used to store the protocol header of a training package. The byte array must be network order. The patch added virtual channel support for iAVF FDIR add/validate/delete filter. iAVF FDIR is Flow Director for Intel Adaptive Virtual Function which can direct Ethernet packets to the queues of the Network Interface Card. Add/delete command is adding or deleting one rule for each virtual channel message, while validate command is just verifying if this rule is valid without any other operations. To add or delete one rule, driver needs to config TCAM and Profile, build training packets which contains the input set value, and send the training packets through FDIR Tx queue. In addition, driver needs to manage the software context to avoid adding duplicated rules, deleting non-existent rule, input set conflicts and other invalid cases. NOTE: Supported pattern/actions and their parse functions are not be included in this patch, they will be added in a separate one.

2021-03-22dm table: Fix zoned model check and zone sectors checkShin'ichiro Kawasaki1-1/+14
Commit 24f6b6036c9e ("dm table: fix zoned iterate_devices based device capability checks") triggered dm table load failure when dm-zoned device is set up for zoned block devices and a regular device for cache. The commit inverted logic of two callback functions for iterate_devices: device_is_zoned_model() and device_matches_zone_sectors(). The logic of device_is_zoned_model() was inverted then all destination devices of all targets in dm table are required to have the expected zoned model. This is fine for dm-linear, dm-flakey and dm-crypt on zoned block devices since each target has only one destination device. However, this results in failure for dm-zoned with regular cache device since that target has both regular block device and zoned block devices. As for device_matches_zone_sectors(), the commit inverted the logic to require all zoned block devices in each target have the specified zone_sectors. This check also fails for regular block device which does not have zones. To avoid the check failures, fix the zone model check and the zone sectors check. For zone model check, introduce the new feature flag DM_TARGET_MIXED_ZONED_MODEL, and set it to dm-zoned target. When the target has this flag, allow it to have destination devices with any zoned model. For zone sectors check, skip the check if the destination device is not a zoned block device. Also add comments and improve an error message to clarify expectations to the two checks.

2021-03-22Bluetooth: verify AMP hci_chan before amp_destroyArchie Pusaka1-0/+1
hci_chan can be created in 2 places: hci_loglink_complete_evt() if it is an AMP hci_chan, or l2cap_conn_add() otherwise. In theory, Only AMP hci_chan should be removed by a call to hci_disconn_loglink_complete_evt(). However, the controller might mess up, call that function, and destroy an hci_chan which is not initiated by hci_loglink_complete_evt(). This patch adds a verification that the destroyed hci_chan must have been init'd by hci_loglink_complete_evt().

2021-03-22rcu: Provide polling interfaces for Tree RCU grace periodsPaul E. McKenney1-0/+2
There is a need for a non-blocking polling interface for RCU grace periods, so this commit supplies start_poll_synchronize_rcu() and poll_state_synchronize_rcu() for this purpose. Note that the existing get_state_synchronize_rcu() may be used if future grace periods are inevitable (perhaps due to a later call_rcu() invocation). The new start_poll_synchronize_rcu() is to be used if future grace periods might not otherwise happen. Finally, poll_state_synchronize_rcu() provides a lockless check for a grace period having elapsed since the corresponding call to either of the get_state_synchronize_rcu() or start_poll_synchronize_rcu(). As with get_state_synchronize_rcu(), the return value from either get_state_synchronize_rcu() or start_poll_synchronize_rcu() is passed in to a later call to either poll_state_synchronize_rcu() or the existing (might_sleep) cond_synchronize_rcu().

The global definition of platform data for the battery management code has no utility after the OF conversion, move the <linux/mfd/abx500/ab8500-bm.h> to be a local file in drivers/power/supply and stop defining the platform data in drivers/power/supply/ab8500_bmdata.c and broadcast to the kernel only to have it assigned as platform data to the MFD cells and then picked back into the same subsystem that defined it in the first place. This kills off a layer of indirection.

NFSD initializes an encode xdr_stream only after the RPC layer has already inserted the RPC Reply header. Thus it behaves differently than xdr_init_encode does, which assumes the passed-in xdr_buf is entirely devoid of content. nfs4proc.c has this server-side stream initialization helper, but it is visible only to the NFSv4 code. Move this helper to a place that can be accessed by NFSv2 and NFSv3 server XDR functions. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

2021-03-22soundwire: add master quirks for bus clash and parityBard Liao1-0/+22
Currently quirks are only allowed for Slave devices. This patch describes the need for two quirks at the Master level. a) bus clash The SoundWire specification allows a Slave device to report a bus clash with the in-band interrupt mechanism when it detects a conflict while driving a bitSlot it owns. This can be a symptom of an electrical conflict or a programming error, and it's vital to detect reliably. Unfortunately, on some platforms, bus clashes are randomly reported by Slave devices after a bus reset, with an interrupt status set even before the bus clash interrupt is enabled. These initial spurious interrupts are not relevant and should optionally be filtered out, while leaving the interrupt mechanism enabled to detect 'true' issues. This patch suggests the addition of a Master level quirk to discard such interrupts. The quirk should in theory have been added at the Slave level, but since the problem was detected with different generations of Slave devices it's hard to point to a specific IP. The problem might also be board-dependent and hence dealing with a Master quirk is simpler. b) parity Additional tests on a new platform with the Maxim 98373 amplifier showed a rare case where the parity interrupt is also thrown on startup, at the same time as bus clashes. This issue only seems to happen infrequently and was only observed during suspend-resume stress tests while audio is streaming. We could make the problem go away by adding a Slave-level quirk, but there is no evidence that the issue is actually a Slave problem: the parity is provided by the Master, which could also set an invalid parity in corner cases.

2021-03-22media: uapi: move VP8 stateless controls out of stagingEzequiel Garcia4-211/+196
Until now, the VP8 V4L2 API was not exported as a public API, and only defined in a private media header (media/vp8-ctrls.h). The reason for this was a concern about the API not complete and ready to support VP8 decoding hardware accelerators. After reviewing the VP8 specification in detail, and now that the API is able to support Cedrus and Hantro G1, we can consider this ready.

Rename to struct v4l2_vp8_loop_filter, which is closer to the VP8 syntax. This change is only cosmetics, but since this API is exposed to userspace, it's worth the trouble to get it consistent.

2021-03-22media: uapi: vp8: Remove "header" from symbol names and macrosEzequiel Garcia2-26/+26
It doesn't seem to add any clarity to have a "header" suffix in controls, struct names and flags. Since this just makes names too long without any benefit, just drop it.
