random: remove ratelimiting for in-kernel unseeded randomness
commit cc1e127bfa95b5fb2f9307e7168bf8b2b45b4c5e upstream. The CONFIG_WARN_ALL_UNSEEDED_RANDOM debug option controls whether the kernel warns about all unseeded randomness or just the first instance. There's some complicated rate limiting and comparison to the previous caller, such that even with CONFIG_WARN_ALL_UNSEEDED_RANDOM enabled, developers still don't see all the messages or even an accurate count of how many were missed. This is the result of basically parallel mechanisms aimed at accomplishing more or less the same thing, added at different points in random.c history, which sort of compete with the first-instance-only limiting we have now. It turns out, however, that nobody cares about the first unseeded randomness instance of in-kernel users. The same first user has been there for ages now, and nobody is doing anything about it. It isn't even clear that anybody _can_ do anything about it. Most places that can do something about it have switched over to using get_random_bytes_wait() or wait_for_random_bytes(), which is the right thing to do, but there is still much code that needs randomness sometimes during init, and as a geeneral rule, if you're not using one of the _wait functions or the readiness notifier callback, you're bound to be doing it wrong just based on that fact alone. So warning about this same first user that can't easily change is simply not an effective mechanism for anything at all. Users can't do anything about it, as the Kconfig text points out -- the problem isn't in userspace code -- and kernel developers don't or more often can't react to it. Instead, show the warning for all instances when CONFIG_WARN_ALL_UNSEEDED_RANDOM is set, so that developers can debug things need be, or if it isn't set, don't show a warning at all. At the same time, CONFIG_WARN_ALL_UNSEEDED_RANDOM now implies setting random.ratelimit_disable=1 on by default, since if you care about one you probably care about the other too. And we can clean up usage around the related urandom_warning ratelimiter as well (whose behavior isn't changing), so that it properly counts missed messages after the 10 message threshold is reached.

random: suppress spammy warnings about unseeded randomness
commit eecabf567422eda02bd179f2707d8fe24f52d888 upstream. Unfortunately, on some models of some architectures getting a fully seeded CRNG is extremely difficult, and so this can result in dmesg getting spammed for a surprisingly long time. This is really bad from a security perspective, and so architecture maintainers really need to do what they can to get the CRNG seeded sooner after the system is booted. However, users can't do anything actionble to address this, and spamming the kernel messages log will only just annoy people. For developers who want to work on improving this situation, CONFIG_WARN_UNSEEDED_RANDOM has been renamed to CONFIG_WARN_ALL_UNSEEDED_RANDOM. By default the kernel will always print the first use of unseeded randomness. This way, hopefully the security obsessed will be happy that there is _some_ indication when the kernel boots there may be a potential issue with that architecture or subarchitecture. To see all uses of unseeded randomness, developers can enable CONFIG_WARN_ALL_UNSEEDED_RANDOM. Signed-off-by: Theodore Ts'o <tytso@mit.edu> Signed-off-by: Jason A.

random: warn when kernel uses unseeded randomness
commit d06bfd1989fe97623b32d6df4ffa6e4338c99dc8 upstream. This enables an important dmesg notification about when drivers have used the crng without it being seeded first. Prior, these errors would occur silently, and so there hasn't been a great way of diagnosing these types of bugs for obscure setups. By adding this as a config option, we can leave it on by default, so that we learn where these issues happen, in the field, will still allowing some people to turn it off, if they really know what they're doing and do not want the log entries. However, we don't leave it _completely_ by default. An earlier version of this patch simply had `default y`. I'd really love that, but it turns out, this problem with unseeded randomness being used is really quite present and is going to take a long time to fix. Thus, as a compromise between log-messages-for-all and nobody-knows, this is `default y`, except it is also `depends on DEBUG_KERNEL`. This will ensure that the curious see the messages while others don't have to. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu> Signed-off-by: Jason A.

ARM: 8800/1: use choice for kernel unwinders
commit f9b58e8c7d031b0daa5c9a9ee27f5a4028ba53ac upstream.
While in theory multiple unwinders could be compiled in, it does
not make sense in practise. Use a choice to make the unwinder
selection mutually exclusive and mandatory.
Already before this commit it has not been possible to deselect
FRAME_POINTER. Remove the obsolete comment.
Furthermore, to produce a meaningful backtrace with FRAME_POINTER
enabled the kernel needs a specific function prologue:
mov ip, sp
stmfd sp!, {fp, ip, lr, pc}
sub fp, ip, #4
To get to the required prologue gcc uses apcs and no-sched-prolog.
This compiler options are not available on clang, and clang is not
able to generate the required prologue. Make the FRAME_POINTER
config symbol depending on !clang.

kmemleak: increase DEBUG_KMEMLEAK_EARLY_LOG_SIZE default to 16K
[ Upstream commit b751c52bb587ae66f773b15204ef7a147467f4c7 ] The current default value (400) is too low on many systems (e.g. some ARM64 platform takes up 1000+ entries). syzbot uses 16000 as default value, and has proved to be enough on beefy configurations, so let's pick that value. This consumes more RAM on boot (each entry is 160 bytes, so in total ~2.5MB of RAM), but the memory would later be freed (early_log is __initdata).

siphash: add cryptographically secure PRF
commit 2c956a60778cbb6a27e0c7a8a52a91378c90e1d1 upstream. SipHash is a 64-bit keyed hash function that is actually a cryptographically secure PRF, like HMAC. Except SipHash is super fast, and is meant to be used as a hashtable keyed lookup function, or as a general PRF for short input use cases, such as sequence numbers or RNG chaining. For the first usage: There are a variety of attacks known as "hashtable poisoning" in which an attacker forms some data such that the hash of that data will be the same, and then preceeds to fill up all entries of a hashbucket. This is a realistic and well-known denial-of-service vector. Currently hashtables use jhash, which is fast but not secure, and some kind of rotating key scheme (or none at all, which isn't good). SipHash is meant as a replacement for jhash in these cases. There are a modicum of places in the kernel that are vulnerable to hashtable poisoning attacks, either via userspace vectors or network vectors, and there's not a reliable mechanism inside the kernel at the moment to fix it. The first step toward fixing these issues is actually getting a secure primitive into the kernel for developers to use. Then we can, bit by bit, port things over to it as deemed appropriate. While SipHash is extremely fast for a cryptographically secure function, it is likely a bit slower than the insecure jhash, and so replacements will be evaluated on a case-by-case basis based on whether or not the difference in speed is negligible and whether or not the current jhash usage poses a real security risk. For the second usage: A few places in the kernel are using MD5 or SHA1 for creating secure sequence numbers, syn cookies, port numbers, or fast random numbers. SipHash is a faster and more fitting, and more secure replacement for MD5 in those situations. Replacing MD5 and SHA1 with SipHash for these uses is obvious and straight-forward, and so is submitted along with this patch series. There shouldn't be much of a debate over its efficacy. Dozens of languages are already using this internally for their hash tables and PRFs. Some of the BSDs already use this in their kernels. SipHash is a widely known high-speed solution to a widely known set of problems, and it's time we catch-up. Signed-off-by: Jason A.

UPSTREAM: bug: Provide toggle for BUG on data corruption
(cherry-picked from de54ebbe26bb371a6f1fbc0593372232f04e3107)
The kernel checks for cases of data structure corruption under some
CONFIGs (e.g. CONFIG_DEBUG_LIST). When corruption is detected, some
systems may want to BUG() immediately instead of letting the system run
with known corruption. Usually these kinds of manipulation primitives can
be used by security flaws to gain arbitrary memory write control. This
provides a new config CONFIG_BUG_ON_DATA_CORRUPTION and a corresponding
macro CHECK_DATA_CORRUPTION for handling these situations. Notably, even
if not BUGing, the kernel should not continue processing the corrupted
structure.
This is inspired by similar hardening by Syed Rameez Mustafa in MSM
kernels, and in PaX and Grsecurity, which is likely in response to earlier
removal of the BUG calls in commit

Kconfig.debug: module: Add debug config to debug modules
There can be scenario where, dynamically loadable modules adds a certain nodes in list data structure and forgot to remove reference from the list while unloading themself. And this can result in fault while accessing those dangling pointers. So If we log the module used address ranges, we could be able to tell exact victim module. And, It will be good to keep these debug logs under a config flag. So, let's add DEBUG_MODULE_LOAD_INFO config and use this in printing module used init and core layout address ranges. e.g: Core layout sections: [ 40.599573] .text [ 40.627074] .plt [ 40.603426] .rodata.str1.8 [ 40.608016] __mcount_loc [ 40.622142] .note.gnu.build-id [ 40.612654] .data [ 40.616438] .gnu.linkonce.this_module [ 40.634909] .bss Init layout sections [ 40.630781] .init.plt [ 40.638591] .symtab [ 40.642573] .strtab After this patch: / # insmod sample.ko [ 26.244768] Hi Mukesh [ 26.247314] Loaded sample: module init layout addresses range: 0xffffff9dbff8a000-0xffffff9dbff8bfff [ 26.256896] sample: core layout addresses range: 0xffffff9dbff85000-0xffffff9dbff88fff / # rmmod sample [ 63.812065] Bye Mukesh [ 63.816318] Unloaded sample: module core layout address range: 0xffffff9dbff85000-0xffffff9dbff88fff Change-Id: I4acfc4f53c561f92ca63fa3c4559148929575580 Signed-off-by: Mukesh Ojha <mojha@codeaurora.org> |

refcount_t: Introduce a special purpose refcount type
Provide refcount_t, an atomic_t like primitive built just for refcounting. It provides saturation semantics such that overflow becomes impossible and thereby 'spurious' use-after-free is avoided.

exit: Add PANIC_ON_RECURSIVE_FAULT Kconfig option
If a recursive fault is detected during do_exit(), tasks are left to sit and wait in an un-interruptible sleep until the system reboots (typically manually). Add Kconfig option to change this behaviour and force a panic. This is particularly important if a critical system task encounters a recursive fault (ex. a kworker). Otherwise, the system may be unusable, but since the scheduler is still running system watchdogs may continue to be pet.

kasan: rework Kconfig settings
commit e7c52b84fb18f08ce49b6067ae6285aca79084a8 upstream. We get a lot of very large stack frames using gcc-7.0.1 with the default -fsanitize-address-use-after-scope --param asan-stack=1 options, which can easily cause an overflow of the kernel stack, e.g. drivers/gpu/drm/i915/gvt/handlers.c:2434:1: warning: the frame size of 46176 bytes is larger than 3072 bytes drivers/net/wireless/ralink/rt2x00/rt2800lib.c:5650:1: warning: the frame size of 23632 bytes is larger than 3072 bytes lib/atomic64_test.c:250:1: warning: the frame size of 11200 bytes is larger than 3072 bytes drivers/gpu/drm/i915/gvt/handlers.c:2621:1: warning: the frame size of 9208 bytes is larger than 3072 bytes drivers/media/dvb-frontends/stv090x.c:3431:1: warning: the frame size of 6816 bytes is larger than 3072 bytes fs/fscache/stats.c:287:1: warning: the frame size of 6536 bytes is larger than 3072 bytes To reduce this risk, -fsanitize-address-use-after-scope is now split out into a separate CONFIG_KASAN_EXTRA Kconfig option, leading to stack frames that are smaller than 2 kilobytes most of the time on x86_64. An earlier version of this patch also prevented combining KASAN_EXTRA with KASAN_INLINE, but that is no longer necessary with gcc-7.0.1. All patches to get the frame size below 2048 bytes with CONFIG_KASAN=y and CONFIG_KASAN_EXTRA=n have been merged by maintainers now, so we can bring back that default now. KASAN_EXTRA=y still causes lots of warnings but now defaults to !COMPILE_TEST to disable it in allmodconfig, and it remains disabled in all other defconfigs since it is a new option. I arbitrarily raise the warning limit for KASAN_EXTRA to 3072 to reduce the noise, but an allmodconfig kernel still has around 50 warnings on gcc-7. I experimented a bit more with smaller stack frames and have another follow-up series that reduces the warning limit for 64-bit architectures to 1280 bytes (without CONFIG_KASAN). With earlier versions of this patch series, I also had patches to address the warnings we get with KASAN and/or KASAN_EXTRA, using a "noinline_if_stackbloat" annotation. That annotation now got replaced with a gcc-8 bugfix (see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81715) and a workaround for older compilers, which means that KASAN_EXTRA is now just as bad as before and will lead to an instant stack overflow in a few extreme cases.

ANDROID: hardlockup: detect hard lockups without NMIs using secondary cpus
This patch adds back the hardlockup detection without NMIs from
<aaf78ec6c898b72>("ANDROID: hardlockup: detect hard lockups without NMIs
using secondary cpus") which was reverted after the hard lockup detection
logic was moved to a separate file in <b969a240448bfd8>("kernel/watchdog.c:
move hardlockup detector to separate file").

time: Remove CONFIG_TIMER_STATS
Currently CONFIG_TIMER_STATS exposes process information across namespaces:
kernel/time/timer_list.c print_timer():
SEQ_printf(m, ", %s/%d", tmp, timer->start_pid);
/proc/timer_list:
#11: <0000000000000000>, hrtimer_wakeup, S:01, do_nanosleep, cron/2570
Given that the tracer can give the same information, this patch entirely
removes CONFIG_TIMER_STATS.

kernel/lib: add additional debug capabilities for data corruption
Data corruptions in the kernel often end up in system crashes that are easier to debug closer to the time of detection. Specifically, if we do not panic immediately after lock or list corruptions have been detected, the problem context is lost in the ensuing system mayhem. Add support for allowing system crash immediately after such corruptions are detected. The CONFIG option controls the enabling/disabling of the feature.

kmemleak : Make kmemleak_stack_scan optional using config
Currently we have kmemleak_stack_scan enabled by default. This can hog the cpu with pre-emption disabled for a long time starving other tasks. Make this optional at compile time, since if required we can always write to sysfs entry and enable this option.

ANDROID: hardlockup: detect hard lockups without NMIs using secondary cpus
Emulate NMIs on systems where they are not available by using timer interrupts on other cpus. Each cpu will use its softlockup hrtimer to check that the next cpu is processing hrtimer interrupts by verifying that a counter is increasing. This patch is useful on systems where the hardlockup detector is not available due to a lack of NMIs, for example most ARM SoCs. Without this patch any cpu stuck with interrupts disabled can cause a hardware watchdog reset with no debugging information, but with this patch the kernel can detect the lockup and panic, which can result in useful debugging info.

lib: spinlock: Cause a watchdog bite on spin_dump
Currently we cause a BUG_ON once a spin_bug is detected, but that causes a whole lot of processing and the other CPUs would have proceeded to perform other actions and the state of the system is moved by the time we can analyze it. Provide an option to trigger a watchdog bite instead so that we can get the traces as close to the issue as possible.

sched: Introduce HMP scheduling
Add a snapshot of all changes associated with the HMP scheduler ported over to the latest kernel version. This will allow proper big Little scheduling for targets that will use this kernel version. The msm-4-4 snapshot is taken at commitcc60f0790f27 (sched: constrain HMP scheduler tunable range with in better way). Please note that this is not an exact snapshot; certain HMP related code has been removed. This includes redundant code, useless CONFIG options, rarely taken error code paths, runtime enable/disable support for the HMP scheduler.

config: Adding the new config parameter CONFIG_PROVE_LOCKING_SMALL for sparc
This new config parameter limits the space used for "Lock debugging: prove locking correctness" by about 4MB. The current sparc systems have the limitation of 32MB size for kernel size including .text, .data and .bss sections. With PROVE_LOCKING feature, the kernel size could grow beyond this limit and causing system boot-up issues. With this option, kernel limits the size of the entries of lock_chains, stack_trace etc., so that kernel fits in required size limit. This is not visible to user and only used for sparc.

latent_entropy: raise CONFIG_FRAME_WARN by default
When building with the latent_entropy plugin, set the default CONFIG_FRAME_WARN to 2048, since some __init functions have many basic blocks that, when instrumented by the latent_entropy plugin, grow beyond 1024 byte stack size on 32-bit builds.

hardlockup: detect hard lockups without NMIs using secondary cpus
Emulate NMIs on systems where they are not available by using timer interrupts on other cpus. Each cpu will use its softlockup hrtimer to check that the next cpu is processing hrtimer interrupts by verifying that a counter is increasing. This patch is useful on systems where the hardlockup detector is not available due to a lack of NMIs, for example most ARM SoCs. Without this patch any cpu stuck with interrupts disabled can cause a hardware watchdog reset with no debugging information, but with this patch the kernel can detect the lockup and panic, which can result in useful debugging info.

samples: move blackfin gptimers-example from Documentation
Move blackfin gptimers-example to samples and remove it from Documentation Makefile. Update samples Kconfig and Makefile to build gptimers-example. blackfin is the last CONFIG_BUILD_DOCSRC target in Documentation/Makefile. Hence this patch also includes changes to remove CONFIG_BUILD_DOCSRC from Makefile and lib/Kconfig.debug and updates VIDEO_PCI_SKELETON dependency on BUILD_DOCSRC. Documentation/Makefile is not deleted to avoid braking make htmldocs and make distclean.
