2024-08-15selftests: net: lib: kill PIDs before del netnsMatthieu Baerts (NGI0)
When deleting netns, it is possible to still have some tasks running, e.g. background tasks like tcpdump running in the background, not stopped because the test has been interrupted. Before deleting the netns, it is then safer to kill all attached PIDs, if any. That should reduce some noises after the end of some tests, and help with the debugging of some issues.

2024-08-15pse-core: Conditionally set current limit during PI regulator registrationOleksij Rempel
Fix an issue where `devm_regulator_register()` would fail for PSE controllers that do not support current limit control, such as simple GPIO-based controllers like the podl-pse-regulator. The `REGULATOR_CHANGE_CURRENT` flag and `max_uA` constraint are now conditionally set only if the `pi_set_current_limit` operation is supported. This change prevents the regulator registration routine from attempting to call `pse_pi_set_current_limit()`, which would return `-EOPNOTSUPP` and cause the registration to fail.

2024-08-15net: thunder_bgx: Fix netdev structure allocationMarc Zyngier
Commit 94833addfaba ("net: thunderx: Unembed netdev structure") had a go at dynamically allocating the netdev structures for the thunderx_bgx driver. This change results in my ThunderX box catching fire (to be fair, it is what it does best). The issues with this change are that: - bgx_lmac_enable() is called *after* bgx_acpi_register_phy() and bgx_init_of_phy(), both expecting netdev to be a valid pointer. - bgx_init_of_phy() populates the MAC addresses for *all* LMACs attached to a given BGX instance, and thus needs netdev for each of them to have been allocated. There is a few things to be said about how the driver mixes LMAC and BGX states which leads to this sorry state, but that's beside the point. To address this, go back to a situation where all netdev structures are allocated before the driver starts relying on them, and move the freeing of these structures to driver removal. Someone brave enough can always go and restructure the driver if they want.

2024-08-14bnxt_en: avoid truncation of per rx run debugfs filenameSimon Horman
Although it seems unlikely in practice - there would need to be rx ring indexes greater than 10^10 - it is theoretically possible for the filename of per rx ring debugfs files to be truncated. This is because although a 16 byte buffer is provided, the length of the filename is restricted to 10 bytes. Remove this restriction and allow the entire buffer to be used. Also reduce the buffer to 12 bytes, which is sufficient. Given that the range of rx ring indexes likely much smaller than the maximum range of a 32-bit signed integer, a smaller buffer could be used, with some further changes. But this change seems simple, robust, and has minimal stack overhead.

2024-08-14netfilter: nf_tables: Add locking for NFT_MSG_GETOBJ_RESET requestsPhil Sutter
Objects' dump callbacks are not concurrency-safe per-se with reset bit set. If two CPUs perform a reset at the same time, at least counter and quota objects suffer from value underrun. Prevent this by introducing dedicated locking callbacks for nfnetlink and the asynchronous dump handling to serialize access.

In theory, dumpreset may fail and invalidate the preceeding log message. Fix this and use the occasion to prepare for object reset locking, which benefits from a few unrelated changes: * Add an early call to nfnetlink_unicast if not resetting which effectively skips the audit logging but also unindents it. * Extract the table's name from the netlink attribute (which is verified via earlier table lookup) to not rely upon validity of the looked up table pointer. * Do not use local variable family, it will vanish.

2024-08-14netfilter: nf_queue: drop packets with cloned unconfirmed conntracksFlorian Westphal
Conntrack assumes an unconfirmed entry (not yet committed to global hash table) has a refcount of 1 and is not visible to other cores. With multicast forwarding this assumption breaks down because such skbs get cloned after being picked up, i.e. ct->use refcount is > 1. Likewise, bridge netfilter will clone broad/mutlicast frames and all frames in case they need to be flood-forwarded during learning phase. For ip multicast forwarding or plain bridge flood-forward this will "work" because packets don't leave softirq and are implicitly serialized. With nfqueue this no longer holds true, the packets get queued and can be reinjected in arbitrary ways. Disable this feature, I see no other solution. After this patch, nfqueue cannot queue packets except the last multicast/broadcast packet.

2024-08-14netfilter: allow ipv6 fragments to arrive on different devicesTom Hughes
Commit 264640fc2c5f4 ("ipv6: distinguish frag queues by device for multicast and link-local packets") modified the ipv6 fragment reassembly logic to distinguish frag queues by device for multicast and link-local packets but in fact only the main reassembly code limits the use of the device to those address types and the netfilter reassembly code uses the device for all packets. This means that if fragments of a packet arrive on different interfaces then netfilter will fail to reassemble them and the fragments will be expired without going any further through the filters.

2024-08-14KVM: x86: Disallow read-only memslots for SEV-ES and SEV-SNP (and TDX)Sean Christopherson
Disallow read-only memslots for SEV-{ES,SNP} VM types, as KVM can't directly emulate instructions for ES/SNP, and instead the guest must explicitly request emulation. Unless the guest explicitly requests emulation without accessing memory, ES/SNP relies on KVM creating an MMIO SPTE, with the subsequent #NPF being reflected into the guest as a #VC. But for read-only memslots, KVM deliberately doesn't create MMIO SPTEs, because except for ES/SNP, doing so requires setting reserved bits in the SPTE, i.e. the SPTE can't be readable while also generating a #VC on writes. Because KVM never creates MMIO SPTEs and jumps directly to emulation, the guest never gets a #VC. And since KVM simply resumes the guest if ES/SNP guests trigger emulation, KVM effectively puts the vCPU into an infinite #NPF loop if the vCPU attempts to write read-only memory. Disallow read-only memory for all VMs with protected state, i.e. for upcoming TDX VMs as well as ES/SNP VMs. For TDX, it's actually possible to support read-only memory, as TDX uses EPT Violation #VE to reflect the fault into the guest, e.g. KVM could configure read-only SPTEs with RX protections and SUPPRESS_VE=0. But there is no strong use case for supporting read-only memslots on TDX, e.g. the main historical usage is to emulate option ROMs, but TDX disallows executing from shared memory. And if someone comes along with a legitimate, strong use case, the restriction can always be lifted for TDX. Don't bother trying to retroactively apply the restriction to SEV-ES VMs that are created as type KVM_X86_DEFAULT_VM. Read-only memslots can't possibly work for SEV-ES, i.e. disallowing such memslots is really just means reporting an error to userspace instead of silently hanging vCPUs. Trying to deal with the ordering between KVM_SEV_INIT and memslot creation isn't worth the marginal benefit it would provide userspace.

2024-08-14Revert "ata: libata-scsi: Honor the D_SENSE bit for CK_COND=1 and no error"Niklas Cassel
This reverts commit 28ab9769117ca944cb6eb537af5599aa436287a4. Sense data can be in either fixed format or descriptor format. SAT-6 revision 1, "10.4.6 Control mode page", defines the D_SENSE bit: "The SATL shall support this bit as defined in SPC-5 with the following exception: if the D_ SENSE bit is set to zero (i.e., fixed format sense data), then the SATL should return fixed format sense data for ATA PASS-THROUGH commands." The libata SATL has always kept D_SENSE set to zero by default. (It is however possible to change the value using a MODE SELECT SG_IO command.) Failed ATA PASS-THROUGH commands correctly respected the D_SENSE bit, however, successful ATA PASS-THROUGH commands incorrectly returned the sense data in descriptor format (regardless of the D_SENSE bit). Commit 28ab9769117c ("ata: libata-scsi: Honor the D_SENSE bit for CK_COND=1 and no error") fixed this bug for successful ATA PASS-THROUGH commands. However, after commit 28ab9769117c ("ata: libata-scsi: Honor the D_SENSE bit for CK_COND=1 and no error"), there were bug reports that hdparm, hddtemp, and udisks were no longer working as expected. These applications incorrectly assume the returned sense data is in descriptor format, without even looking at the RESPONSE CODE field in the returned sense data (to see which format the returned sense data is in). Considering that there will be broken versions of these applications around roughly forever, we are stuck with being bug compatible with older kernels.
