[PATCH MANUALSEL 4.19 1/2] KVM: x86: Handle SRCU initialization failure during page track init

by Sasha Levin

From: Haimin Zhang <tcs_kernel(a)tencent.com> [ Upstream commit eb7511bf9182292ef1df1082d23039e856d1ddfb ] Check the return of init_srcu_struct(), which can fail due to OOM, when initializing the page track mechanism. Lack of checking leads to a NULL pointer deref found by a modified syzkaller.

[PATCH 1/1] net: cdc_ncm: Allow for dwNtbOutMaxSize to be unset or zero

by Lee Jones

Currently, due to the sequential use of min_t() and clamp_t() macros, in cdc_ncm_check_tx_max(), if dwNtbOutMaxSize is not set, the logic sets tx_max to 0. This is then used to allocate the data area of the SKB requested later in cdc_ncm_fill_tx_frame(). This does not cause an issue presently because when memory is allocated during initialisation phase of SKB creation, more memory (512b) is allocated than is required for the SKB headers alone (320b), leaving some space (512b - 320b = 192b) for CDC data (172b). However, if more elements (for example 3 x u64 = [24b]) were added to one of the SKB header structs, say 'struct skb_shared_info', increasing its original size (320b [320b aligned]) to something larger (344b [384b aligned]), then suddenly the CDC data (172b) no longer fits in the spare SKB data area (512b - 384b = 128b). Consequently the SKB bounds checking semantics fails and panics: skbuff: skb_over_panic: text:ffffffff830a5b5f len:184 put:172 \ head:ffff888119227c00 data:ffff888119227c00 tail:0xb8 end:0x80 dev:<NULL> ------------[ cut here ]------------ kernel BUG at net/core/skbuff.c:110!

[PATCH v3] i2c: i801: Safely share SMBus with BIOS/ACPI

by Hector Martin

The i801 controller provides a locking mechanism that the OS is supposed to use to safely share the SMBus with ACPI AML or other firmware. Previously, Linux attempted to get out of the way of ACPI AML entirely, but left the bus locked if it used it before the first AML access. This causes AML implementations that *do* attempt to safely share the bus to time out if Linux uses it first; notably, this regressed ACPI video backlight controls on 2015 iMacs after 01590f361e started instantiating SPD EEPROMs on boot. Commit 065b6211a8 fixed the immediate problem of leaving the bus locked, but we can do better. The controller does have a proper locking mechanism, so let's use it as intended. Since we can't rely on the BIOS doing this properly, we implement the following logic: - If ACPI AML uses the bus at all, we make a note and disable power management. The latter matches already existing behavior. - When we want to use the bus, we attempt to lock it first. If the locking attempt times out, *and* ACPI hasn't tried to use the bus at all yet, we cautiously go ahead and assume the BIOS forgot to unlock the bus after boot. This preserves existing behavior. - We always unlock the bus after a transfer. - If ACPI AML tries to use the bus (except trying to lock it) while we're in the middle of a transfer, or after we've determined locking is broken, we know we cannot safely share the bus and give up. Upon first usage of SMBus by ACPI AML, if nothing has gone horribly wrong so far, users will see: i801_smbus 0000:00:1f.4: SMBus controller is shared with ACPI AML. This seems safe so far. If locking the SMBus times out, users will see: i801_smbus 0000:00:1f.4: BIOS left SMBus locked And if ACPI AML tries to use the bus concurrently with Linux, or it previously used the bus and we failed to subsequently lock it as above, the driver will give up and users will get: i801_smbus 0000:00:1f.4: BIOS uses SMBus unsafely i801_smbus 0000:00:1f.4: Driver SMBus register access inhibited This fixes the regression introduced by 01590f361e, and further allows safely sharing the SMBus on 2015 iMacs. Tested by running `i2cdump` in a loop while changing backlight levels via the ACPI video device.

[PATCH 1/2] x86/mpparse: avoid overwriting boot_cpu_physical_apicid

by Kevin Mitchell

When booting with ACPI unavailable or disabled, get_smp_config() ends up calling MP_processor_info() for each CPU found in the MPS table. Previously, this resulted in boot_cpu_physical_apicid getting unconditionally overwritten by the apicid of whatever processor had the CPU_BOOTPROCESSOR flag. This occurred even if boot_cpu_physical_apicid had already been more reliably determined in register_lapic_address() by calling read_apic_id() from the actual boot processor. Ordinariliy, this is not a problem because the boot processor really is the one with the CPU_BOOTPROCESSOR flag. However, kexec is an exception in which the kernel may be booted from any processor regardless of the MPS table contents. In this case, boot_cpu_physical_apicid may not indicate the actual boot processor. This was particularly problematic when the second kernel was booted with NR_CPUS fewer than the number of physical processors. It's the job of generic_processor_info() to decide which CPUs to bring up in this case. That obviously must include the real boot processor which it takes care to save a slot for. It relies upon the contents of boot_cpu_physical_apicid to do this, which if incorrect, may result in the boot processor getting left out. This condition can be discovered by smp_sanity_check() and rectified by adding the boot processor to the phys_cpu_present_map with the warning "weird, boot CPU (#%d) not listed by the BIOS". However, commit 3e730dad3b6da ("x86/apic: Unify interrupt mode setup for SMP-capable system") caused setup_local_APIC() to be called before this could happen resulting in a BUG_ON(!apic->apic_id_registered()): [ 0.655452] ------------[ cut here ]------------ [ 0.660610] Kernel BUG at setup_local_APIC+0x74/0x280 [verbose debug info unavailable] [ 0.669466] invalid opcode: 0000 [#1] SMP [ 0.673948] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.19.109.Ar-16509018.eostrunkkernel419 #1 [ 0.683670] Hardware name: Quanta Quanta LY6 (1LY6UZZ0FBC), BIOS 1.0.6.0-e7d6a55 11/26/2015 [ 0.693007] RIP: 0010:setup_local_APIC+0x74/0x280 [ 0.698264] Code: 80 e4 fe bf f0 00 00 00 89 c6 48 8b 05 0f 1a 8e 00 ff 50 10 e8 12 53 fd ff 48 8b 05 00 1a 8e 00 ff 90 a0 00 00 00 85 c0 75 02 <0f> 0b 48 8b 05 ed 19 8e 00 41 be 00 02 00 00 ff 90 b0 00 00 00 48 [ 0.719251] RSP: 0000:ffffffff81a03e20 EFLAGS: 00010246 [ 0.725091] RAX: 0000000000000000 RBX: 0000000000000003 RCX: 0000000000000000 [ 0.733066] RDX: 0000000000000000 RSI: 000000000000000f RDI: 0000000000000020 [ 0.741041] RBP: ffffffff81a03e98 R08: 0000000000000002 R09: 0000000000000000 [ 0.749014] R10: ffffffff81a204e0 R11: ffffffff81b50ea7 R12: 0000000000000000 [ 0.756989] R13: ffffffff81aef920 R14: ffffffff81af60a0 R15: 0000000000000000 [ 0.764965] FS: 0000000000000000(0000) GS:ffff888036800000(0000) knlGS:0000000000000000 [ 0.774007] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 0.780427] CR2: ffff888035c01000 CR3: 0000000035a08000 CR4: 00000000000006b0 [ 0.788401] Call Trace: [ 0.791137] ? amd_iommu_prepare+0x15/0x2a [ 0.795717] apic_bsp_setup+0x55/0x75 [ 0.799808] apic_intr_mode_init+0x169/0x16e [ 0.804579] x86_late_time_init+0x10/0x17 [ 0.809062] start_kernel+0x37e/0x3fe [ 0.813154] x86_64_start_reservations+0x2a/0x2c [ 0.818316] x86_64_start_kernel+0x72/0x75 [ 0.822886] secondary_startup_64+0xa4/0xb0 [ 0.827564] ---[ end trace 237b64da0fd9b22e ]--- This change avoids these issues by only setting boot_cpu_physical_apicid from the MPS table if it is not already set, which can occur in the construct_default_ISA_mptable() path. Otherwise, boot_cpu_physical_apicid will already have been set in register_lapic_address() and should therefore remain untouched. Looking through all the places where boot_cpu_physical_apicid is accessed, nearly all of them assume that boot_cpu_physical_apicid should match read_apic_id() on the booting processor. The only place that might intend to use the BSP apicid listed in the MPS table is amd_numa_init(), which explicitly requires boot_cpu_physical_apicid to be the lowest apicid of all processors. Ironically, due to the early exit short circuit in early_get_smp_config(), it instead gets boot_cpu_physical_apicid = read_apic_id() rather than the MPS table BSP. The behaviour of amd_numa_init() is therefore unaffected by this change.

[PATCH] gpio: Revert regression in sysfs-gpio (gpiolib.c)

by Marcelo Roberto Jimenez

Some GPIO lines have stopped working after the patch commit 2ab73c6d8323f ("gpio: Support GPIO controllers without pin-ranges") And this has supposedly been fixed in the following patches commit 89ad556b7f96a ("gpio: Avoid using pin ranges with !PINCTRL") commit 6dbbf84603961 ("gpiolib: Don't free if pin ranges are not defined") But an erratic behavior where some GPIO lines work while others do not work has been introduced. This patch reverts those changes so that the sysfs-gpio interface works properly again. Signed-off-by: Marcelo Roberto Jimenez <marcelo.jimenez(a)gmail.com> --- Hi, My system is ARM926EJ-S rev 5 (v5l) (AT91SAM9G25), the board is an ACME Systems Arietta. The system used sysfs-gpio to manage a few gpio lines, and I have noticed that some have stopped working. The test script is very simple: #! /bin/bash cd /sys/class/gpio/ echo 24 > export cd pioA24 echo out > direction echo 0 > value cat value echo 1 > value cat value echo 0 > value cat value echo 1 > value cat value cd .. echo 24 > unexport In a "good" kernel, this script outputs 0, 1, 0, 1. In a bad kernel, the output result is 1, 1, 1, 1. Also it must be possible to run this script twice without errors, that was the issue with the gpiochip_generic_free() call that had been addressed in another patch. In my system PINCTRL is automatically selected by SOC_AT91SAM9 [=y] && ARCH_AT91 [=y] && ARCH_MULTI_V5 [=y] So it is not an option to disable it to make it work.
