STEs format for Connect-X5 and Connect-X6DX different. Currently, on Connext-X6DX the SW steering would break at some point when building STEs w/o giving a proper error message. Fix this by checking the STE format of the current device when initializing domain: add mlx5_ifc definitions for Connect-X6DX SW steering, read FW capability to get the current format version, and check this version when domain is being created.

The "skb" is freed by the transmit code in cxgb4_ofld_send() and we shouldn't use it again. But in the current code, if we hit an error later on in the function then the clean up code will call kfree_skb(skb) and so it causes a double free. Set the "skb" to NULL and that makes the kfree_skb() a no-op. Fixes: d25f2f71 ("crypto: chtls - Program the TLS session Key") Signed-off-by:

Currently .get_state() and .apply() use dev_get_drvdata() on the struct device related to the pwm chip. This only works after .probe() called platform_set_drvdata() which in this driver happens only after pwmchip_add() and so comes possibly too late. Instead of setting the driver data earlier use the traditional container_of approach as this way the driver data is conceptually and computational nearer.

Lilith >_> and Claudio Bozzato of Cisco Talos security team reported that collect_syscall() improperly casts the syscall registers to 64-bit values leaking the uninitialized last 24 bytes on 32-bit platforms, that are visible in /proc/self/syscall. The cause is that info->data.args are u64 while syscall_get_arguments() uses longs, as hinted by the bogus pointer cast in the function. Let's just proceed like the other call places, by retrieving the registers into an array of longs before assigning them to the caller's array. This was successfully tested on x86_64, i386 and ppc32.

The .x25_addr[] address comes from the user and is not necessarily NUL terminated. This leads to a couple problems. The first problem is that the strlen() in x25_bind() can read beyond the end of the buffer. The second problem is more subtle and could result in memory corruption. The call tree is: x25_connect() --> x25_write_internal() --> x25_addr_aton() The .x25_addr[] buffers are copied to the "addresses" buffer from x25_write_internal() so it will lead to stack corruption. Verify that the strings are NUL terminated and return -EINVAL if they are not.

Pull arm64 fixes from Will Deacon: "I'm sad to say that we've got an unusually large arm64 fixes pull for rc7 which addresses numerous significant instrumentation issues with our entry code. Without these patches, lockdep is hopelessly unreliable in some configurations [1,2] and syzkaller is therefore not a lot of use because it's so noisy. Although much of this has always been broken, it appears to have been exposed more readily by other changes such as 044d0d6d ("lockdep: Only trace IRQ edges") and general lockdep improvements around IRQ tracing and NMIs. Fixing this properly required moving much of the instrumentation hooks from our entry assembly into C, which Mark has been working on for the last few weeks. We're not quite ready to move to the recently added generic functions yet, but the code here has been deliberately written to mimic that closely so we can look at cleaning things up once we have a bit more breathing room. Having said all that, the second version of these patches was posted last week and I pushed it into our CI (kernelci and cki) along with a commit which forced on PROVE_LOCKING, NOHZ_FULL and CONTEXT_TRACKING_FORCE. The result? We found a real bug in the md/raid10 code [3]. Oh, and there's also a really silly typo patch that's unrelated.

We need loop, not just single check, to clean all pending entries. Additionally move mt76_worker_disable/enable after !mt76_has_tx_pending() as we want to tx_worker to run to process tx queues, while we wait for exactly that. I was a bit worried about accessing q->queued without lock, but mt76_worker_disable() -> kthread_park() should assure this value will be seen updated on other cpus.

The NO_160 flag specifies if the device doesn't have 160 MHz support, but we errorneously assumed the opposite. If the flag was set, we were considering that 160 MHz was supported, but it's actually the opposite. Fix it by inverting the bits, i.e. NO_160 is 0x1 and 160 is 0x0.

With commit 58c644ba ("sched/idle: Fix arch_cpu_idle() vs tracing") common code calls arch_cpu_idle() with a lockdep state that tells irqs are on. This doesn't work very well for s390: psw_idle() will enable interrupts to wait for an interrupt. As soon as an interrupt occurs the interrupt handler will verify if the old context was psw_idle(). If that is the case the interrupt enablement bits in the old program status word will be cleared. A subsequent test in both the external as well as the io interrupt handler checks if in the old context interrupts were enabled. Due to the above patching of the old program status word it is assumed the old context had interrupts disabled, and therefore a call to TRACE_IRQS_OFF (aka trace_hardirqs_off_caller) is skipped. Which in turn makes lockdep incorrectly "think" that interrupts are enabled within the interrupt handler. Fix this by unconditionally calling TRACE_IRQS_OFF when entering interrupt handlers. Also call unconditionally TRACE_IRQS_ON when leaving interrupts handlers. This leaves the special psw_idle() case, which now returns with interrupts disabled, but has an "irqs on" lockdep state. So callers of psw_idle() must adjust the state on their own, if required. This is currently only __udelay_disabled(). Fixes: 58c644ba ("sched/idle: Fix arch_cpu_idle() vs tracing") Acked-by:

The directed MSIs are delivered to CPUs whose address is written to the MSI message address. The current code assumes that a CPU logical number (as it is seen by the kernel) is also the CPU address. The above assumption is not correct, as the CPU address is rather the value returned by STAP instruction. That value does not necessarily match the kernel logical CPU number.

drivers/vdpa/mlx5/ uses vhost_iotlb*() interfaces, so select VHOST_IOTLB to make them be built. However, if VHOST_IOTLB is the only VHOST symbol that is set/enabled, the object file still won't be built because drivers/Makefile won't descend into drivers/vhost/ to build it, so make drivers/Makefile build the needed binary whenever VHOST_IOTLB is set, like it does for VHOST_RING. Fixes these build errors: ERROR: modpost: "vhost_iotlb_itree_next" [drivers/vdpa/mlx5/mlx5_vdpa.ko] undefined! ERROR: modpost: "vhost_iotlb_itree_first" [drivers/vdpa/mlx5/mlx5_vdpa.ko] undefined!
