2022-12-05xfrm: add TX datapath support for IPsec packet offload modeLeon Romanovsky
In IPsec packet mode, the device is going to encrypt and encapsulate packets that are associated with offloaded policy. After successful policy lookup to indicate if packets should be offloaded or not, the stack forwards packets to the device to do the magic.

2022-12-05xfrm: allow state packet offload modeLeon Romanovsky
Allow users to configure xfrm states with packet offload mode. The packet mode must be requested both for policy and state, and such requires us to do not implement fallback. We explicitly return an error if requested packet mode can't be configured.

2022-12-05xfrm: add new packet offload flagLeon Romanovsky
In the next patches, the xfrm core code will be extended to support new type of offload - packet offload. In that mode, both policy and state should be specially configured in order to perform whole offloaded data path. Full offload takes care of encryption, decryption, encapsulation and other operations with headers. As this mode is new for XFRM policy flow, we can "start fresh" with flag bits and release first and second bit for future use.

2022-12-04bpf: Add dummy type reference to nf_conn___init to fix type deduplicationToke Høiland-Jørgensen
The bpf_ct_set_nat_info() kfunc is defined in the nf_nat.ko module, and takes as a parameter the nf_conn___init struct, which is allocated through the bpf_xdp_ct_alloc() helper defined in the nf_conntrack.ko module. However, because kernel modules can't deduplicate BTF types between each other, and the nf_conn___init struct is not referenced anywhere in vmlinux BTF, this leads to two distinct BTF IDs for the same type (one in each module). This confuses the verifier, as described here: https://lore.kernel.org/all/87leoh372s.fsf@toke.dk/ As a workaround, add an explicit BTF_TYPE_EMIT for the type in net/filter.c, so the type definition gets included in vmlinux BTF. This way, both modules can refer to the same type ID (as they both build on top of vmlinux BTF), and the verifier is no longer confused. v2: - Use BTF_TYPE_EMIT (which is a statement so it has to be inside a function definition; use xdp_func_proto() for this, since this is mostly xdp-related).

2022-12-04bpf: Do not mark certain LSM hook arguments as trustedYonghong Song
Martin mentioned that the verifier cannot assume arguments from LSM hook sk_alloc_security being trusted since after the hook is called, the sk ref_count is set to 1. This will overwrite the ref_count changed by the bpf program and may cause ref_count underflow later on. I then further checked some other hooks. For example, for bpf_lsm_file_alloc() hook in fs/file_table.c, f->f_cred = get_cred(cred); error = security_file_alloc(f); if (unlikely(error)) { file_free_rcu(&f->f_rcuhead); return ERR_PTR(error); } atomic_long_set(&f->f_count, 1); The input parameter 'f' to security_file_alloc() cannot be trusted as well. Specifically, I investiaged bpf_map/bpf_prog/file/sk/task alloc/free lsm hooks. Except bpf_map_alloc and task_alloc, arguments for all other hooks should not be considered as trusted. This may not be a complete list, but it covers common usage for sk and task.

2022-12-04bpf: Handle MEM_RCU type properlyYonghong Song
Commit 9bb00b2895cb ("bpf: Add kfunc bpf_rcu_read_lock/unlock()") introduced MEM_RCU and bpf_rcu_read_lock/unlock() support. In that commit, a rcu pointer is tagged with both MEM_RCU and PTR_TRUSTED so that it can be passed into kfuncs or helpers as an argument. Martin raised a good question in [1] such that the rcu pointer, although being able to accessing the object, might have reference count of 0. This might cause a problem if the rcu pointer is passed to a kfunc which expects trusted arguments where ref count should be greater than 0. This patch makes the following changes related to MEM_RCU pointer: - MEM_RCU pointer might be NULL (PTR_MAYBE_NULL). - Introduce KF_RCU so MEM_RCU ptr can be acquired with a KF_RCU tagged kfunc which assumes ref count of rcu ptr could be zero. - For mem access 'b = ptr->a', say 'ptr' is a MEM_RCU ptr, and 'a' is tagged with __rcu as well. Let us mark 'b' as MEM_RCU | PTR_MAYBE_NULL.

Heiner Kallweit says: ==================== net: add and use netdev_sw_irq_coalesce_default_on() There are reports about r8169 not reaching full line speed on certain systems (e.g. SBC's) with a 2.5Gbps link. There was a time when hardware interrupt coalescing was enabled per default, but this was changed due to ASPM-related issues on few systems. Meanwhile we have sysfs attributes for controlling kind of "software interrupt coalescing" on the GRO level. However most distros and users don't know about it. So lets set a conservative default for both involved parameters. Users can still override the defaults via sysfs. Don't enable these settings on the fast ethernet chip versions, they are slow enough. Even with these conservative setting interrupt load on my 1Gbps test system reduced significantly. Follow Jakub's suggestion and put this functionality into net core so that other MAC drivers can reuse it. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2022-12-03r8169: enable GRO software interrupt coalescing per defaultHeiner Kallweit
There are reports about r8169 not reaching full line speed on certain systems (e.g. SBC's) with a 2.5Gbps link. There was a time when hardware interrupt coalescing was enabled per default, but this was changed due to ASPM-related issues on few systems. So let's use software interrupt coalescing instead and enable it using new function netdev_sw_irq_coalesce_default_on(). Even with these conservative settings interrupt load on my 1Gbps test system reduced significantly. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.

2022-12-03net: add netdev_sw_irq_coalesce_default_on()Heiner Kallweit
Add a helper for drivers wanting to set SW IRQ coalescing by default. The related sysfs attributes can be used to override the default values. Follow Jakub's suggestion and put this functionality into net core so that drivers wanting to use software interrupt coalescing per default don't have to open-code it. Note that this function needs to be called before the netdevice is registered.

2022-12-02x86/bugs: Make sure MSR_SPEC_CTRL is updated properly upon resume from S3Pawan Gupta
The "force" argument to write_spec_ctrl_current() is currently ambiguous as it does not guarantee the MSR write. This is due to the optimization that writes to the MSR happen only when the new value differs from the cached value. This is fine in most cases, but breaks for S3 resume when the cached MSR value gets out of sync with the hardware MSR value due to S3 resetting it. When x86_spec_ctrl_current is same as x86_spec_ctrl_base, the MSR write is skipped. Which results in SPEC_CTRL mitigations not getting restored. Move the MSR write from write_spec_ctrl_current() to a new function that unconditionally writes to the MSR. Update the callers accordingly and rename functions.
