* Documentation/locking/locktypes: Update migrate_disable() bits.Sebastian Andrzej Siewior2021-11-301-6/+3
| | | | | | | | | | | | | | | | | The initial implementation of migrate_disable() for mainline was a wrapper around preempt_disable(). RT kernels substituted this with a real migrate disable implementation. Later on mainline gained true migrate disable support, but the documentation was not updated. Update the documentation, remove the claims about migrate_disable() mapping to preempt_disable() on non-PREEMPT_RT kernels. Fixes: 74d862b682f51 ("sched: Make migrate_disable/enable() independent of RT") Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Link: https://lore.kernel.org/bpf/20211127163200.10466-2-bigeasy@linutronix.de
* net,lsm,selinux: revert the security_sctp_assoc_established() hookPaul Moore2021-11-141-10/+12
| | | | | | | | | | | | | | | | | | | | | | This patch reverts two prior patches, e7310c94024c ("security: implement sctp_assoc_established hook in selinux") and 7c2ef0240e6a ("security: add sctp_assoc_established hook"), which create the security_sctp_assoc_established() LSM hook and provide a SELinux implementation. Unfortunately these two patches were merged without proper review (the Reviewed-by and Tested-by tags from Richard Haines were for previous revisions of these patches that were significantly different) and there are outstanding objections from the SELinux maintainers regarding these patches. Work is currently ongoing to correct the problems identified in the reverted patches, as well as others that have come up during review, but it is unclear at this point in time when that work will be ready for inclusion in the mainline kernel. In the interest of not keeping objectionable code in the kernel for multiple weeks, and potentially a kernel release, we are reverting the two problematic patches.

Unfortunately, it's real make and number is not known due to obscure and missing documentation and lack of writing on the display assembly itself. So the natural alternative that came to mind is to name the panel after the device that contained it (an Android tablet). Hopefully that isn't an issue. I can confirm that the parameters that I've obtained are correct since they came from a dump of the original Android OS.

The default output is 32768Hz. This is to provide the i.MX8M CKIL clock. Once the RTC driver is probed, the clock is disabled and all i.MX8M functionality depending on the 32 KHz clock will halt. In our case the whole system halts and a power cycle is required. Referencing the pcf85063 directly results in a deadlock. The kernel will see, that i.MX8M system clock needs the RTC clock and do probe deferral. But the i.MX8M I2C module never becomes usable without the i.MX8M CKIL clock and thus the RTC's clock will not be probed. So from the kernel's perspective this is a chicken-and-egg problem. Technically everything is fine by not touching anything, since the RTC clock correctly enables the clock on reset (i.e. on battery backup power loss). A workaround for this issue is describing the square wave pin as fixed-clock, which is registered early and basically how this pin is used on the i.MX8M. This addresses the exact same issue as in commit f765e349c3e1 ("rtc: m41t80: add support for fixed clock").

If it wasn't then the a second attempt is made to lock the page. However if the first attempt failed it's unlikely a second attempt will succeed, and the retry adds complexity. So clean this up by removing the retry and MIGRATE_PFN_LOCKED flag. Destination pages are also meant to have the MIGRATE_PFN_LOCKED flag set, but nothing actually checks that.

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

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.
