2023-12-08bpf: Add some comments to stack representationAndrei Matei
Add comments to the datastructure tracking the stack state, as the mapping between each stack slot and where its state is stored is not entirely obvious.

2023-12-08KVM: clean up directives to compile out irqfdsPaolo Bonzini
Keep all #ifdef CONFIG_HAVE_KVM_IRQCHIP parts of eventfd.c together, and compile out the irqfds field of struct kvm if the symbol is not defined. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2023-12-08KVM: remove deprecated UAPIsPaolo Bonzini
The deprecated interfaces were removed 15 years ago. KVM's device assignment was deprecated in 4.2 and removed 6.5 years ago; the only interest might be in compiling ancient versions of QEMU, but QEMU has been using its own imported copy of the kernel headers since June 2011. So again we go into archaeology territory; just remove the cruft. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2023-12-08KVM: remove CONFIG_HAVE_KVM_IRQFDPaolo Bonzini
All platforms with a kernel irqchip have support for irqfd. Unify the two configuration items so that userspace can expect to use irqfd to inject interrupts into the irqchip. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2023-12-08KVM: remove CONFIG_HAVE_KVM_EVENTFDPaolo Bonzini
virt/kvm/eventfd.c is compiled unconditionally, meaning that the ioeventfds member of struct kvm is accessed unconditionally. CONFIG_HAVE_KVM_EVENTFD therefore must be defined for KVM common code to compile successfully, remove it. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2023-12-08netlink: Return unsigned value for nla_len()Kees Cook
The return value from nla_len() is never expected to be negative, and can never be more than struct nlattr::nla_len (a u16). Adjust the prototype on the function. This will let GCC's value range optimization passes know that the return can never be negative, and can never be larger than u16. As recently discussed[1], this silences the following warning in GCC 12+: net/wireless/nl80211.c: In function 'nl80211_set_cqm_rssi.isra': net/wireless/nl80211.c:12892:17: warning: 'memcpy' specified bound 18446744073709551615 exceeds maximum object size 9223372036854775807 [-Wstringop-overflow=] 12892 | memcpy(cqm_config->rssi_thresholds, thresholds, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 12893 | flex_array_size(cqm_config, rssi_thresholds, | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 12894 | n_thresholds)); | ~~~~~~~~~~~~~~ A future change would be to clamp the subtraction to make sure it never wraps around if nla_len is somehow less than NLA_HDRLEN, which would have the additional benefit of being defensive in the face of nlattr corruption or logic errors.

2023-12-08Use READ/WRITE_ONCE() for IP local_port_range.David Laight
Commit 227b60f5102cd added a seqlock to ensure that the low and high port numbers were always updated together. This is overkill because the two 16bit port numbers can be held in a u32 and read/written in a single instruction. More recently 91d0b78c5177f added support for finer per-socket limits. The user-supplied value is 'high << 16 | low' but they are held separately and the socket options protected by the socket lock. Use a u32 containing 'high << 16 | low' for both the 'net' and 'sk' fields and use READ_ONCE()/WRITE_ONCE() to ensure both values are always updated together. Change (the now trival) inet_get_local_port_range() to a static inline to optimise the calling code. (In particular avoiding returning integers by reference.)

2023-12-08ASoC: wm8996: Convert to GPIO descriptorsLinus Walleij

Lorenzo points out that we effectively clear all unknown flags from PIO when copying them to userspace in the netlink RTM_NEWPREFIX notification. We could fix this one at a time as new flags are defined, or in one fell swoop - I choose the latter. We could either define 6 new reserved flags (reserved1..6) and handle them individually (and rename them as new flags are defined), or we could simply copy the entire unmodified byte over - I choose the latter. This unfortunately requires some anonymous union/struct magic, so we add a static assert on the struct size for a little extra safety.

2023-12-08crypto: algif_skcipher - Fix stream cipher chainingHerbert Xu
Unlike algif_aead which is always issued in one go (thus limiting the maximum size of the request), algif_skcipher has always allowed unlimited input data by cutting them up as necessary and feeding the fragments to the underlying algorithm one at a time. However, because of deficiencies in the API, this has been broken for most stream ciphers such as arc4 or chacha. This is because they have an internal state in addition to the IV that must be preserved in order to continue processing. Fix this by using the new skcipher state API.

2023-12-08crypto: skcipher - Make use of internal stateHerbert Xu
This patch adds code to the skcipher/lskcipher API to make use of the internal state if present. In particular, the skcipher lskcipher wrapper will allocate a buffer for the IV/state and feed that to the underlying lskcipher algorithm. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2023-12-08crypto: skcipher - Add internal state supportHerbert Xu
Unlike chaining modes such as CBC, stream ciphers other than CTR usually hold an internal state that must be preserved if the operation is to be done piecemeal. This has not been represented in the API, resulting in the inability to split up stream cipher operations. This patch adds the basic representation of an internal state to skcipher and lskcipher. In the interest of backwards compatibility, the default has been set such that existing users are assumed to be operating in one go as opposed to piecemeal. With the new API, each lskcipher/skcipher algorithm has a new attribute called statesize. For skcipher, this is the size of the buffer that can be exported or imported similar to ahash. For lskcipher, instead of providing a buffer of ivsize, the user now has to provide a buffer of ivsize + statesize. Each skcipher operation is assumed to be final as they are now, but this may be overridden with a request flag. When the override occurs, the user may then export the partial state and reimport it later. For lskcipher operations this is reversed. All operations are not final and the state will be exported unless the FINAL bit is set. However, the CONT bit still has to be set for the state to be used.

2023-12-08crypto: hisilicon/qm - save capability registers in qm init processZhiqi Song
In previous capability register implementation, qm irq related values were read from capability registers dynamically when needed. But in abnormal scenario, e.g. the core is timeout and the device needs to soft reset and reset failed after disabling the MSE, the device can not be removed normally, causing the following call trace: | Call trace: | pci_irq_vector+0xfc/0x140 | hisi_qm_uninit+0x278/0x3b0 [hisi_qm] | hpre_remove+0x16c/0x1c0 [hisi_hpre] | pci_device_remove+0x6c/0x264 | device_release_driver_internal+0x1ec/0x3e0 | device_release_driver+0x3c/0x60 | pci_stop_bus_device+0xfc/0x22c | pci_stop_and_remove_bus_device+0x38/0x70 | pci_iov_remove_virtfn+0x108/0x1c0 | sriov_disable+0x7c/0x1e4 | pci_disable_sriov+0x4c/0x6c | hisi_qm_sriov_disable+0x90/0x160 [hisi_qm] | hpre_remove+0x1a8/0x1c0 [hisi_hpre] | pci_device_remove+0x6c/0x264 | device_release_driver_internal+0x1ec/0x3e0 | driver_detach+0x168/0x2d0 | bus_remove_driver+0xc0/0x230 | driver_unregister+0x58/0xdc | pci_unregister_driver+0x40/0x220 | hpre_exit+0x34/0x64 [hisi_hpre] | __arm64_sys_delete_module+0x374/0x620 [...] | Call trace: | free_msi_irqs+0x25c/0x300 | pci_disable_msi+0x19c/0x264 | pci_free_irq_vectors+0x4c/0x70 | hisi_qm_pci_uninit+0x44/0x90 [hisi_qm] | hisi_qm_uninit+0x28c/0x3b0 [hisi_qm] | hpre_remove+0x16c/0x1c0 [hisi_hpre] | pci_device_remove+0x6c/0x264 [...] The reason for this call trace is that when the MSE is disabled, the value of capability registers in the BAR space become invalid. This will make the subsequent unregister process get the wrong irq vector through capability registers and get the wrong irq number by pci_irq_vector(). So add a capability table structure to pre-store the valid value of the irq information capability register in qm init process, avoid obtaining invalid capability register value after the MSE is disabled.

2023-12-07KVM x86/xen: add an override for PVCLOCK_TSC_STABLE_BITPaul Durrant
Unless explicitly told to do so (by passing 'clocksource=tsc' and 'tsc=stable:socket', and then jumping through some hoops concerning potential CPU hotplug) Xen will never use TSC as its clocksource. Hence, by default, a Xen guest will not see PVCLOCK_TSC_STABLE_BIT set in either the primary or secondary pvclock memory areas. This has led to bugs in some guest kernels which only become evident if PVCLOCK_TSC_STABLE_BIT *is* set in the pvclocks. Hence, to support such guests, give the VMM a new Xen HVM config flag to tell KVM to forcibly clear the bit in the Xen pvclocks.

2023-12-07cgroup: Move rcu_head up near the top of cgroup_rootWaiman Long
Commit d23b5c577715 ("cgroup: Make operations on the cgroup root_list RCU safe") adds a new rcu_head to the cgroup_root structure and kvfree_rcu() for freeing the cgroup_root. The current implementation of kvfree_rcu(), however, has the limitation that the offset of the rcu_head structure within the larger data structure must be less than 4096 or the compilation will fail. See the macro definition of __is_kvfree_rcu_offset() in include/linux/rcupdate.h for more information. By putting rcu_head below the large cgroup structure, any change to the cgroup structure that makes it larger run the risk of causing build failure under certain configurations. Commit 77070eeb8821 ("cgroup: Avoid false cacheline sharing of read mostly rstat_cpu") happens to be the last straw that breaks it. Fix this problem by moving the rcu_head structure up before the cgroup structure.
