The changes to the files were kept minimal, and the controversial commit that used to take noise from the fast_pool (f227e3ec3b5c) was reverted. Instead, a dedicated "net_rand_noise" per_cpu variable is fed from various sources of activities (networking, scheduling) to perturb the SipHash state using fast, non-trivially predictable data, instead of keeping it fully deterministic. The goal is essentially to make any occasional memory leakage or brute-force attempt useless.

But i2c_acpi_install_space_handler() had a call to acpi_walk_dep_device_list() hidden (that is I missed it) at the end of it, so as an unwanted side-effect now acpi_walk_dep_device_list() was also being called before i2c_acpi_register_devices(). Move the acpi_walk_dep_device_list() call to the end of i2c_acpi_register_devices(), so that it is once again called *after* the i2c_client-s hanging of the adapter have been created.

3744741 | Willy Tarreau | 10 August 2020, 08:27:42 UTC | random32: add noise from network and scheduling activity With the removal of the interrupt perturbations in previous random32 change (random32: make prandom_u32() output unpredictable), the PRNG has become 100% deterministic again. While SipHash is expected to be way more robust against brute force than the previous Tausworthe LFSR, there's still the risk that whoever has even one temporary access to the PRNG's internal state is able to predict all subsequent draws till the next reseed (roughly every minute). This may happen through a side channel attack or any data leak. This patch restores the spirit of commit f227e3ec3b5c ("random32: update the net random state on interrupt and activity") in that it will perturb the internal PRNG's statee using externally collected noise, except that it will not pick that noise from the random pool's bits nor upon interrupt, but will rather combine a few elements along the Tx path that are collectively hard to predict, such as dev, skb and txq pointers, packet length and jiffies values. These ones are combined using a single round of SipHash into a single long variable that is mixed with the net_rand_state upon each invocation. The operation was inlined because it produces very small and efficient code, typically 3 xor, 2 add and 2 rol. The performance was measured to be the same (even very slightly better) than before the switch to SipHash; on a 6-core 12-thread Core i7-8700k equipped with a 40G NIC (i40e), the connection rate dropped from 556k/s to 555k/s while the SYN cookie rate grew from 5.38 Mpps to 5.45 Mpps.

c51f8f8 | George Spelvin | 09 August 2020, 06:57:44 UTC | random32: make prandom_u32() output unpredictable Non-cryptographic PRNGs may have great statistical properties, but are usually trivially predictable to someone who knows the algorithm, given a small sample of their output. An LFSR like prandom_u32() is particularly simple, even if the sample is widely scattered bits. It turns out the network stack uses prandom_u32() for some things like random port numbers which it would prefer are *not* trivially predictable. Predictability led to a practical DNS spoofing attack. Oops. This patch replaces the LFSR with a homebrew cryptographic PRNG based on the SipHash round function, which is in turn seeded with 128 bits of strong random key. (The authors of SipHash have *not* been consulted about this abuse of their algorithm.) Speed is prioritized over security; attacks are rare, while performance is always wanted. Replacing all callers of prandom_u32() is the quick fix. Whether to reinstate a weaker PRNG for uses which can tolerate it is an open question.

7737706 | Vitaly Kuznetsov | 24 October 2020, 08:13:24 UTC | KVM: ioapic: break infinite recursion on lazy EOI During shutdown the IOAPIC trigger mode is reset to edge triggered while the vfio-pci INTx is still registered with a resampler. This allows us to get into an infinite loop: ioapic_set_irq -> ioapic_lazy_update_eoi -> kvm_ioapic_update_eoi_one -> kvm_notify_acked_irq -> kvm_notify_acked_gsi -> (via irq_acked fn ptr) irqfd_resampler_ack -> kvm_set_irq -> (via set fn ptr) kvm_set_ioapic_irq -> kvm_ioapic_set_irq -> ioapic_set_irq Commit 8be8f932e3db ("kvm: ioapic: Restrict lazy EOI update to edge-triggered interrupts", 2020-05-04) acknowledges that this recursion loop exists and tries to avoid it at the call to ioapic_lazy_update_eoi, but at this point the scenario is already set, we have an edge interrupt with resampler on the same gsi. Fortunately, the only user of irq ack notifiers (in addition to resamplefd) is i8254 timer interrupt reinjection. These are edge-triggered, so in principle they would need the call to kvm_ioapic_update_eoi_one from ioapic_lazy_update_eoi, but they already disable AVIC(*), so they don't need the lazy EOI behavior. Therefore, remove the call to kvm_ioapic_update_eoi_one from ioapic_lazy_update_eoi. This fixes CVE-2020-27152. Note that this issue cannot happen with SR-IOV assigned devices because virtual functions do not have INTx, only MSI.

9c5743d | Rasmus Villemoes | 23 October 2020, 20:31:54 UTC | x86/uaccess: fix code generation in put_user() Quoting https://gcc.gnu.org/onlinedocs/gcc/Local-Register-Variables.html: You can define a local register variable and associate it with a specified register... The only supported use for this feature is to specify registers for input and output operands when calling Extended asm (see Extended Asm). This may be necessary if the constraints for a particular machine don't provide sufficient control to select the desired register. On 32-bit x86, this is used to ensure that gcc will put an 8-byte value into the %edx:%eax pair, while all other cases will just use the single register %eax (%rax on x86-64). While the _ASM_AX actually just expands to "%eax", note this comment next to get_user() which does something very similar: * The use of _ASM_DX as the register specifier is a bit of a * simplification, as gcc only cares about it as the starting point * and not size: for a 64-bit value it will use %ecx:%edx on 32 bits * (%ecx being the next register in gcc's x86 register sequence), and * %rdx on 64 bits. However, getting this to work requires that there is no code between the assignment to the local register variable and its use as an input to the asm() which can possibly clobber any of the registers involved - including evaluation of the expressions making up other inputs. In the current code, the ptr expression used directly as an input may cause such code to be emitted. For example, Sean Christopherson observed that with KASAN enabled and ptr being current->set_child_tid (from chedule_tail()), the load of current->set_child_tid causes a call to __asan_load8() to be emitted immediately prior to the __put_user_4 call, and Naresh Kamboju reports that various mmstress tests fail on KASAN-enabled builds. It's also possible to synthesize a broken case without KASAN if one uses "foo()" as the ptr argument, with foo being some "extern u64 __user *foo(void);" (though I don't know if that appears in real code). Fix it by making sure ptr gets evaluated before the assignment to __val_pu, and add a comment that __val_pu must be the last thing computed before the asm() is entered.

The wrappers masks out any old invalid O_NONBLOCK flags, reports in the syslog if the old O_NONBLOCK value was used and then calls the target syscall with the new O_NONBLOCK value.

Zero out the local statfs file for good measure. Previously, statfs updates would be read in from the local statfs inode and synced to the master statfs inode during recovery. We now use the statfs updates in the journal head to update the master statfs inode instead of reading in from the local statfs inode. To preserve backward compatibility with kernels that can't do this, we still need to keep the local statfs inode up to date by writing changes to it. At some point in the future, we can do away with the local statfs inodes altogether and keep the statfs changes solely in the journal.

The max_reconnects and reconnect_delay are set in common code prior to calling the transport to create the controller. This change checks if the default reconnect delay is being used, and if so, it adjusts it to a shorter period (2s) for the nvme-fc transport. It does so by calculating the controller loss tmo window, changing the value of the reconnect delay, and then recalculating the maximum number of reconnect attempts allowed.

52793d6 | James Smart | 16 October 2020, 21:06:27 UTC | nvme-fc: fix io timeout to abort I/O Currently, an I/O timeout unconditionally invokes nvme_fc_error_recovery() which checks for LIVE or CONNECTING state. If live, the routine resets the controller which initiates a reconnect - which is valid. If CONNECTING, err_work is scheduled. Err_work then calls the terminate_io routine, which also checks for CONNECTING and noops any further action on outstanding I/O. The result is nothing happened to the timed out io. As such, if the command was dropped on the wire, it will never timeout / complete, and the connect process will hang. Change the behavior of the io timeout routine to unconditionally abort the I/O. I/O completion handling will note that an io failed due to an abort and will terminate the connection / association as needed. If the abort was unable to happen, continue with a call to nvme_fc_error_recovery(). To ensure something different happens in nvme_fc_error_recovery() rework it so at it will abort all I/Os on the association to force a failure. As I/O aborts now may occur outside of delete_association, counting for completion must be wary and only count those aborted during delete_association when TERMIO is set on the controller.

In order to avoid making this degradation permanent, KVM must periodically reclaim shattered NX largepages by zapping them and allowing them to be rebuilt in the page fault handler. With this patch, the TDP MMU does not respect KVM's rate limiting on reclaim. It traverses the entire TDP structure every time. This will be addressed in a future patch.

bb18842 | Ben Gardon | 14 October 2020, 18:26:50 UTC | kvm: x86/mmu: Add TDP MMU PF handler Add functions to handle page faults in the TDP MMU. These page faults are currently handled in much the same way as the x86 shadow paging based MMU, however the ordering of some operations is slightly different. Future patches will add eager NX splitting, a fast page fault handler, and parallel page faults. Tested by running kvm-unit-tests and KVM selftests on an Intel Haswell machine.

879bc2d | Helge Deller | 19 October 2020, 14:57:50 UTC | hil/parisc: Disable HIL driver when it gets stuck When starting a HP machine with HIL driver but without an HIL keyboard or HIL mouse attached, it may happen that data written to the HIL loop gets stuck (e.g. because the transaction queue is full). Usually one will then have to reboot the machine because all you see is and endless output of: Transaction add failed: transaction already queued? In the higher layers hp_sdc_enqueue_transaction() is called to queued up a HIL packet. This function returns an error code, and this patch adds the necessary checks for this return code and disables the HIL driver if further packets can't be sent. Tested on a HP 730 and a HP 715/64 machine. Signed-off-by: Helge Deller <deller@gmx.de> Cc: <stable@vger.kernel.org> | 22 October 2020, 20:44:35 UTC |
