2020-09-25sched/fair: Relax constraint on task's load during load balanceVincent Guittot
Some UCs like 9 always running tasks on 8 CPUs can't be balanced and the load balancer currently migrates the waiting task between the CPUs in an almost random manner. The success of a rq pulling a task depends of the value of nr_balance_failed of its domains and its ability to be faster than others to detach it. This behavior results in an unfair distribution of the running time between tasks because some CPUs will run most of the time, if not always, the same task whereas others will share their time between several tasks. Instead of using nr_balance_failed as a boolean to relax the condition for detaching task, the LB will use nr_balanced_failed to relax the threshold between the tasks'load and the imbalance. This mecanism prevents the same rq or domain to always win the load balance fight.

2020-09-25sched/fair: Fix wrong cpu selecting from isolated domainXunlei Pang
We've met problems that occasionally tasks with full cpumask (e.g. by putting it into a cpuset or setting to full affinity) were migrated to our isolated cpus in production environment. After some analysis, we found that it is due to the current select_idle_smt() not considering the sched_domain mask. Steps to reproduce on my 31-CPU hyperthreads machine: 1. with boot parameter: "isolcpus=domain,2-31" (thread lists: 0,16 and 1,17) 2. cgcreate -g cpu:test; cgexec -g cpu:test "test_threads" 3. some threads will be migrated to the isolated cpu16~17. Fix it by checking the valid domain mask in select_idle_smt().

2020-09-25sched/rt: Disable RT_RUNTIME_SHARE by defaultDaniel Bristot de Oliveira
The RT_RUNTIME_SHARE sched feature enables the sharing of rt_runtime between CPUs, allowing a CPU to run a real-time task up to 100% of the time while leaving more space for non-real-time tasks to run on the CPU that lend rt_runtime. The problem is that a CPU can easily borrow enough rt_runtime to allow a spinning rt-task to run forever, starving per-cpu tasks like kworkers, which are non-real-time by design. This patch disables RT_RUNTIME_SHARE by default, avoiding this problem. The feature will still be present for users that want to enable it, though.

2020-09-25sched/deadline: Fix stale throttling on de-/boosted tasksLucas Stach
When a boosted task gets throttled, what normally happens is that it's immediately enqueued again with ENQUEUE_REPLENISH, which replenishes the runtime and clears the dl_throttled flag. There is a special case however: if the throttling happened on sched-out and the task has been deboosted in the meantime, the replenish is skipped as the task will return to its normal scheduling class. This leaves the task with the dl_throttled flag set. Now if the task gets boosted up to the deadline scheduling class again while it is sleeping, it's still in the throttled state. The normal wakeup however will enqueue the task with ENQUEUE_REPLENISH not set, so we don't actually place it on the rq. Thus we end up with a task that is runnable, but not actually on the rq and neither a immediate replenishment happens, nor is the replenishment timer set up, so the task is stuck in forever-throttled limbo. Clear the dl_throttled flag before dropping back to the normal scheduling class to fix this issue.

2020-09-25fbcon: Fix global-out-of-bounds read in fbcon_get_font()Peilin Ye
fbcon_get_font() is reading out-of-bounds. A malicious user may resize `vc->vc_font.height` to a large value, causing fbcon_get_font() to read out of `fontdata`. fbcon_get_font() handles both built-in and user-provided fonts. Fortunately, recently we have added FONT_EXTRA_WORDS support for built-in fonts, so fix it by adding range checks using FNTSIZE(). This patch depends on patch "fbdev, newport_con: Move FONT_EXTRA_WORDS macros into linux/font.h", and patch "Fonts: Support FONT_EXTRA_WORDS macros for built-in fonts".

2020-09-25Fonts: Support FONT_EXTRA_WORDS macros for built-in fontsPeilin Ye
syzbot has reported an issue in the framebuffer layer, where a malicious user may overflow our built-in font data buffers. In order to perform a reliable range check, subsystems need to know `FONTDATAMAX` for each built-in font. Unfortunately, our font descriptor, `struct console_font` does not contain `FONTDATAMAX`, and is part of the UAPI, making it infeasible to modify it. For user-provided fonts, the framebuffer layer resolves this issue by reserving four extra words at the beginning of data buffers. Later, whenever a function needs to access them, it simply uses the following macros: Recently we have gathered all the above macros to <linux/font.h>. Let us do the same thing for built-in fonts, prepend four extra words (including `FONTDATAMAX`) to their data buffers, so that subsystems can use these macros for all fonts, no matter built-in or user-provided. This patch depends on patch "fbdev, newport_con: Move FONT_EXTRA_WORDS macros into linux/font.h".

2020-09-25xfrm: Use correct address family in xfrm_state_findHerbert Xu
The struct flowi must never be interpreted by itself as its size depends on the address family. Therefore it must always be grouped with its original family value. In this particular instance, the original family value is lost in the function xfrm_state_find. Therefore we get a bogus read when it's coupled with the wrong family which would occur with inter- family xfrm states. This patch fixes it by keeping the original family value. Note that the same bug could potentially occur in LSM through the xfrm_state_pol_flow_match hook. I checked the current code there and it seems to be safe for now as only secid is used which is part of struct flowi_common. But that API should be changed so that so that we don't get new bugs in the future. We could do that by replacing fl with just secid or adding a family field.

The x509 certificate supports SM2-with-SM3 type certificate verification. Because certificate verification requires ZA in addition to tbs data, ZA also depends on elliptic curve parameters and public key data, so you need to access tbs in sig and calculate ZA.

2020-09-25crypto: af_alg - add extra parameters for DRBG interfaceElena Petrova
Extend the user-space RNG interface: 1. Add entropy input via ALG_SET_DRBG_ENTROPY setsockopt option; 2. Add additional data input via sendmsg syscall. This allows DRBG to be tested with test vectors, for example for the purpose of CAVP testing, which otherwise isn't possible. To prevent erroneous use of entropy input, it is hidden under CRYPTO_USER_API_RNG_CAVP config option and requires CAP_SYS_ADMIN to succeed.
