| * net: udp: correct the document for udp_memMenglong Dong2021-11-051-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | udp_mem is a vector of 3 INTEGERs, which is used to limit the number of pages allowed for queueing by all UDP sockets. However, sk_has_memory_pressure() in __sk_mem_raise_allocated() always return false for udp, as memory pressure is not supported by udp, which means that __sk_mem_raise_allocated() will fail once pages allocated for udp socket exceeds udp_mem[0]. Therefor, udp_mem[0] is the only one that limit the number of pages. However, the document of udp_mem just express that udp_mem[2] is the limitation. So, just fix it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is to move secid and peer_secid from endpoint to association, and pass asoc to sctp_assoc_request and sctp_sk_clone instead of ep. As ep is the local endpoint and asoc represents a connection, and in SCTP one sk/ep could have multiple asoc/connection, saving secid/peer_secid for new asoc will overwrite the old asoc's. Note that since asoc can be passed as NULL, security_sctp_assoc_request() is moved to the place right after the new_asoc is created in sctp_sf_do_5_1B_init() and sctp_sf_do_unexpected_init(). v1->v2: - fix the description of selinux_netlbl_skbuff_setsid(), as Jakub noticed. - fix the annotation in selinux_sctp_assoc_request(), as Richard Noticed.

In order to activate core scheduling the caller is expected to specify the scope of the new core scheduling domain. For example, passing 2 in the 4th argument of prctl(PR_SCHED_CORE, PR_SCHED_CORE_CREATE, <pid>, 2, 0); would indicate that the new core scheduling domain encompasses all tasks in the process group of <pid>. Specifying 0 would only create a core scheduling domain for the thread identified by <pid> and 2 would encompass the whole thread-group of <pid>. Note, the values 0, 1, and 2 correspond to PIDTYPE_PID, PIDTYPE_TGID, and PIDTYPE_PGID. A first version tried to expose those values directly to which I objected because: - PIDTYPE_* is an enum that is kernel internal which we should not expose to userspace directly. - PIDTYPE_* indicates what a given struct pid is used for it doesn't express a scope. But what the 4th argument of PR_SCHED_CORE prctl() expresses is the scope of the operation, i.e. the scope of the core scheduling domain at creation time. So Eugene's patch now simply introduces three new defines PR_SCHED_CORE_SCOPE_THREAD, PR_SCHED_CORE_SCOPE_THREAD_GROUP, and PR_SCHED_CORE_SCOPE_PROCESS_GROUP. They simply express what happens. This has been on the mailing list for quite a while with all relevant scheduler folks Cced. I announced multiple times that I'd pick this up if I don't see or her anyone else doing it. None of this touches proper scheduler code but only concerns uapi so I think this is fine. With core scheduling being quite common now for vm managers (e.g. moving individual vcpu threads into their own core scheduling domain) and container managers (e.g. moving the init process into its own core scheduling domain and letting all created children inherit it) having to rely on raw numbers passed as the 4th argument in prctl() is a bit annoying and everyone is starting to come up with their own defines" * tag 'kernel.sys.v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: uapi/linux/prctl: provide macro definitions for the PR_SCHED_CORE type argument

Christian has suggested to provide additional macro definitions that convey the meaning of the type argument more in alignment with its actual usage, and this patch does exactly that.

This is already supported using the "qcom,controlled-remotely" property. However, for some reason another possible configuration is that the remote processor is responsible for powering up the BAM, but we are still responsible for initializing it (e.g. resetting it etc). Add a "qcom,powered-remotely" property to describe that configuration.

For this to work correctly the guest must not touch more memory pages than its target memory size as otherwise the PoD cache will be exhausted and the guest is crashed as a result of that. In extreme cases ballooning down might not be finished today before the init process is started, which can consume lots of memory. In order to avoid random boot crashes in such cases, add a late init call to wait for ballooning down having finished for PVH/HVM guests. Warn on console if initial ballooning fails, panic() after stalling for more than 3 minutes per default. Add a module parameter for changing this timeout.

Therefore it is not backward-compatible. Similarly to the R329, the D1 has three watchdog instances, and only one of them has the "soft reset" registers. So that instance needs an extra compatible string.

However, starting with R329, LOSC (OSC32k) is added as an alternative clock source, with a bit to switch between them. Since 24 MHz / 750 == 32 kHz, not 32.768 kHz, the hardware adjusts the cycle counts to keep the timeouts independent of the clock source. This keeps the programming interface backward-compatible. Furthermore, the R329 has two watchdogs: one for use by the ARM CPUs at 0x20000a0, and a second one for use by the DSPs at 0x7020400. The first of these adds two more new registers, to allow software to immediately assert the SoC reset signal. Add an additional "-reset" suffix to signify the presence of this feature.

Clean this up and replace it with a generic soc node to keep it agnostic of the SoC or board compatibles that are outside the scope of this binding.

However the co-processors enter low-power modes independent to that of the application processor and their states are expected to remain unaltered across system suspend/resume cycles. To achieve this behavior let's drop the load state power-domain and replace them with the qmp property for all SoCs supporting low power mode signalling. Due to the current broken load state implementation, we can afford the binding breakage that ensues and the remoteproc functionality will remain the same when using newer kernels with older dtbs.

Therefore driver should not enforce specific trigger type - edge falling - but instead rely on Devicetree to configure it. The Maxim 14577/77836 datasheets describe the interrupt line as active low with a requirement of acknowledge from the CPU therefore the edge falling is not correct. The interrupt line is shared between PMIC and charger driver, so using level sensitive interrupt is here especially important to avoid races. With an edge configuration in case if first PMIC signals interrupt followed shortly after by the RTC, the interrupt might not be yet cleared/acked thus the second one would not be noticed.
