2020-11-06bpf: Implement get_current_task_btf and RET_PTR_TO_BTF_IDKP Singh
The currently available bpf_get_current_task returns an unsigned integer which can be used along with BPF_CORE_READ to read data from the task_struct but still cannot be used as an input argument to a helper that accepts an ARG_PTR_TO_BTF_ID of type task_struct. In order to implement this helper a new return type, RET_PTR_TO_BTF_ID, is added. This is similar to RET_PTR_TO_BTF_ID_OR_NULL but does not require checking the nullness of returned pointer.

2020-11-06bpf: Implement task local storageKP Singh
Similar to bpf_local_storage for sockets and inodes add local storage for task_struct. The life-cycle of storage is managed with the life-cycle of the task_struct. i.e. the storage is destroyed along with the owning task with a callback to the bpf_task_storage_free from the task_free LSM hook. The BPF LSM allocates an __rcu pointer to the bpf_local_storage in the security blob which are now stackable and can co-exist with other LSMs. The userspace map operations can be done by using a pid fd as a key passed to the lookup, update and delete operations.

Now that all callbacks are recursion safe, reverse the meaning of the RECURSION flag and rename it from RECURSION_SAFE to simply RECURSION. Now only callbacks that request to have recursion protecting it will have the added trampoline to do so. Also remove the outdated comment about "PER_CPU" when determining to use the ftrace_ops_assist_func.

2020-11-06ftrace: Optimize testing what context current is inSteven Rostedt (VMware)
The preempt_count() is not a simple location in memory, it could be part of per_cpu code or more. Each access to preempt_count(), or one of its accessor functions (like in_interrupt()) takes several cycles. By reading preempt_count() once, and then doing tests to find the context against the value return is slightly faster than using in_nmi() and in_interrupt().

2020-11-06ftrace: Move the recursion testing into global headersSteven Rostedt (VMware)
Currently, if a callback is registered to a ftrace function and its ftrace_ops does not have the RECURSION flag set, it is encapsulated in a helper function that does the recursion for it. Really, all the callbacks should have their own recursion protection for performance reasons. But they should not all implement their own. Move the recursion helpers to global headers, so that all callbacks can use them.

This means some very few #ifdef in code, but it allows us to enlist the compiler to make sure this stuff isn't used anymore. More important, only legacy drivers change drm_device (for the legacy_dev_list shadow attach management), therefore this is prep to allow modern drivers to have a const driver struct.

Add support to configure SAE PWE preference from userspace to drivers in both AP and STA modes. This is needed for cases where the driver takes care of Authentication frame processing (SME in the driver) so that correct enforcement of the acceptable PWE derivation mechanism can be performed. The userspace applications can pass the sae_pwe value using the NL80211_ATTR_SAE_PWE attribute in the NL80211_CMD_CONNECT and NL80211_CMD_START_AP commands to the driver. This allows selection between the hunting-and-pecking loop and hash-to-element options for PWE derivation. For backwards compatibility, this new attribute is optional and if not included, the driver is notified of the value being unspecified.

2020-11-06crypto: af_alg - avoid undefined behavior accessing salg_nameEric Biggers
Commit 3f69cc60768b ("crypto: af_alg - Allow arbitrarily long algorithm names") made the kernel start accepting arbitrarily long algorithm names in sockaddr_alg. However, the actual length of the salg_name field stayed at the original 64 bytes. This is broken because the kernel can access indices >= 64 in salg_name, which is undefined behavior -- even though the memory that is accessed is still located within the sockaddr structure. It would only be defined behavior if the array were properly marked as arbitrary-length (either by making it a flexible array, which is the recommended way these days, or by making it an array of length 0 or 1). We can't simply change salg_name into a flexible array, since that would break source compatibility with userspace programs that embed sockaddr_alg into another struct, or (more commonly) declare a sockaddr_alg like 'struct sockaddr_alg sa = { .salg_name = "foo" };'. One solution would be to change salg_name into a flexible array only when '#ifdef __KERNEL__'. However, that would keep userspace without an easy way to actually use the longer algorithm names. Instead, add a new structure 'sockaddr_alg_new' that has the flexible array field, and expose it to both userspace and the kernel. Make the kernel use it correctly in alg_bind(). This addresses the syzbot report "UBSAN: array-index-out-of-bounds in alg_bind" (https://syzkaller.appspot.com/bug?extid=92ead4eb8e26a26d465e).

2020-11-05net: dsa: Give drivers the chance to veto certain upper devicesVladimir Oltean
Some switches rely on unique pvids to ensure port separation in standalone mode, because they don't have a port forwarding matrix configurable in hardware. So, setups like a group of 2 uppers with the same VLAN, swp0.100 and swp1.100, will cause traffic tagged with VLAN 100 to be autonomously forwarded between these switch ports, in spite of there being no bridge between swp0 and swp1. These drivers need to prevent this from happening. They need to have VLAN filtering enabled in standalone mode (so they'll drop frames tagged with unknown VLANs) and they can only accept an 8021q upper on a port as long as it isn't installed on any other port too. So give them the chance to veto bad user requests.

2020-11-05net: dsa: Add tag handling for Hirschmann Hellcreek switchesKurt Kanzenbach
The Hirschmann Hellcreek TSN switches have a special tagging protocol for frames exchanged between the CPU port and the master interface. The format is a one byte trailer indicating the destination or origin port. It's quite similar to the Micrel KSZ tagging. That's why the implementation is based on that code.

2020-11-04scsi: ufs: Add DeepSleep featureAdrian Hunter
DeepSleep is a UFS v3.1 feature that achieves the lowest power consumption of the device, apart from power off. In DeepSleep mode, no commands are accepted, and the only way to exit is using a hardware reset or power cycle. This patch assumes that if a power cycle was an option, then power off would be preferable, so only exit via a hardware reset is supported. Drivers that wish to support DeepSleep need to set a new capability flag UFSHCD_CAP_DEEPSLEEP and provide a hardware reset via the existing ->device_reset() callback. It is assumed that UFS devices with wspecversion >= 0x310 support DeepSleep.
