[PATCH for-v5.10.x 1/1] psi: Fix uaf issue when psi trigger is destroyed while being polled

by Suren Baghdasaryan

commit a06247c6804f1a7c86a2e5398a4c1f1db1471848 upstream. With write operation on psi files replacing old trigger with a new one, the lifetime of its waitqueue is totally arbitrary. Overwriting an existing trigger causes its waitqueue to be freed and pending poll() will stumble on trigger->event_wait which was destroyed. Fix this by disallowing to redefine an existing psi trigger. If a write operation is used on a file descriptor with an already existing psi trigger, the operation will fail with EBUSY error. Also bypass a check for psi_disabled in the psi_trigger_destroy as the flag can be flipped after the trigger is created, leading to a memory leak.

[PATCH 5.10] KVM: x86: Forcibly leave nested virt when SMM state is toggled

by Tadeusz Struk

From: Sean Christopherson <seanjc(a)google.com> Commit f7e570780efc5cec9b2ed1e0472a7da14e864fdb upstream. Please apply it to 5.10.y. It fixes the following syzbot issue: Link: https://syzkaller.appspot.com/bug?id=c46ee6f22a68171154cdd9217216b2a02cf4b7… Forcibly leave nested virtualization operation if userspace toggles SMM state via KVM_SET_VCPU_EVENTS or KVM_SYNC_X86_EVENTS. If userspace forces the vCPU out of SMM while it's post-VMXON and then injects an SMI, vmx_enter_smm() will overwrite vmx->nested.smm.vmxon and end up with both vmxon=false and smm.vmxon=false, but all other nVMX state allocated. Don't attempt to gracefully handle the transition as (a) most transitions are nonsencial, e.g. forcing SMM while L2 is running, (b) there isn't sufficient information to handle all transitions, e.g. SVM wants access to the SMRAM save state, and (c) KVM_SET_VCPU_EVENTS must precede KVM_SET_NESTED_STATE during state restore as the latter disallows putting the vCPU into L2 if SMM is active, and disallows tagging the vCPU as being post-VMXON in SMM if SMM is not active. Abuse of KVM_SET_VCPU_EVENTS manifests as a WARN and memory leak in nVMX due to failure to free vmcs01's shadow VMCS, but the bug goes far beyond just a memory leak, e.g. toggling SMM on while L2 is active puts the vCPU in an architecturally impossible state.

[PATCH 4.14.y 0/2] netfilter: nat: fix soft lockup when most ports are used

by Florian Westphal

First patch removes old rovers, they are inherently racy and cause packet drops/delays. Second patch avoids iterating entire range of ports: It takes way too long when most tuples are in use. First patch is slightly mangled; nf_nat_proto_common.c needs minor adjustment in context.

[PATCH v2] PCI: imx6: Allow to probe when dw_pcie_wait_for_link() fails

by Fabio Estevam

The intention of commit 886a9c134755 ("PCI: dwc: Move link handling into common code") was to standardize the behavior of link down as explained in its commit log: "The behavior for a link down was inconsistent as some drivers would fail probe in that case while others succeed. Let's standardize this to succeed as there are usecases where devices (and the link) appear later even without hotplug. For example, a reconfigured FPGA device." The pci-imx6 still fails to probe when the link is not present, which causes the following warning: imx6q-pcie 8ffc000.pcie: Phy link never came up imx6q-pcie: probe of 8ffc000.pcie failed with error -110 ------------[ cut here ]------------ WARNING: CPU: 0 PID: 30 at drivers/regulator/core.c:2257 _regulator_put.part.0+0x1b8/0x1dc Modules linked in: CPU: 0 PID: 30 Comm: kworker/u2:2 Not tainted 5.15.0-next-20211103 #1 Hardware name: Freescale i.MX6 SoloX (Device Tree) Workqueue: events_unbound async_run_entry_fn [<c0111730>] (unwind_backtrace) from [<c010bb74>] (show_stack+0x10/0x14) [<c010bb74>] (show_stack) from [<c0f90290>] (dump_stack_lvl+0x58/0x70) [<c0f90290>] (dump_stack_lvl) from [<c012631c>] (__warn+0xd4/0x154) [<c012631c>] (__warn) from [<c0f87b00>] (warn_slowpath_fmt+0x74/0xa8) [<c0f87b00>] (warn_slowpath_fmt) from [<c076b4bc>] (_regulator_put.part.0+0x1b8/0x1dc) [<c076b4bc>] (_regulator_put.part.0) from [<c076b574>] (regulator_put+0x2c/0x3c) [<c076b574>] (regulator_put) from [<c08c3740>] (release_nodes+0x50/0x178) Fix this problem by ignoring the dw_pcie_wait_for_link() error like it is done on the other dwc drivers.

[PATCH] eeprom: ee1004: limit i2c reads to I2C_SMBUS_BLOCK_MAX

by Jonas Malaco

Commit effa453168a7 ("i2c: i801: Don't silently correct invalid transfer size") revealed that ee1004_eeprom_read() did not properly limit how many bytes to read at once. In particular, i2c_smbus_read_i2c_block_data_or_emulated() takes the length to read as an u8. If count == 256 after taking into account the offset and page boundary, the cast to u8 overflows. And this is common when user space tries to read the entire EEPROM at once. To fix it, limit each read to I2C_SMBUS_BLOCK_MAX (32) bytes, already the maximum length i2c_smbus_read_i2c_block_data_or_emulated() allows.

[PATCH] ARM: davinci: da850-evm: Avoid NULL pointer dereference

by Nathan Chancellor

With newer versions of GCC, there is a panic in da850_evm_config_emac() when booting multi_v5_defconfig in QEMU under the palmetto-bmc machine: Unable to handle kernel NULL pointer dereference at virtual address 00000020 pgd = (ptrval) [00000020] *pgd=00000000 Internal error: Oops: 5 [#1] PREEMPT ARM Modules linked in: CPU: 0 PID: 1 Comm: swapper Not tainted 5.15.0 #1 Hardware name: Generic DT based system PC is at da850_evm_config_emac+0x1c/0x120 LR is at do_one_initcall+0x50/0x1e0 The emac_pdata pointer in soc_info is NULL because davinci_soc_info only gets populated on davinci machines but da850_evm_config_emac() is called on all machines via device_initcall().

[PATCH] Revert "drivers: bus: simple-pm-bus: Add support for probing simple bus only devices"

by Kevin Hilman

This reverts commit d5f13bbb51046537b2c2b9868177fb8fe8a6a6e9. This change related to fw_devlink was backported to v5.10 but has severaly other dependencies that were not backported. As discussed with the original author, the best approach for v5.10 is to revert.
