2022-02-05hwrng: core - explicit ordering of initcallsDominik Brodowski1-1/+1
hw-random device drivers depend on the hw-random core being initialized. Make this ordering explicit, also for the case these drivers are built-in. As the core itself depends on misc_register() which is set up at subsys_initcall time, advance the initialization of the core (only) to the fs_initcall() level.

2022-02-05crypto: api - Move cryptomgr soft dependency into algapiHerbert Xu2-1/+1
The soft dependency on cryptomgr is only needed in algapi because if algapi isn't present then no algorithms can be loaded. This also fixes the case where api is built-in but algapi is built as a module as the soft dependency would otherwise get lost.

2022-02-04tcp: take care of mixed splice()/sendmsg(MSG_ZEROCOPY) caseEric Dumazet1-14/+19
syzbot found that mixing sendpage() and sendmsg(MSG_ZEROCOPY) calls over the same TCP socket would again trigger the infamous warning in inet_sock_destruct() WARN_ON(sk_forward_alloc_get(sk)); While Talal took into account a mix of regular copied data and MSG_ZEROCOPY one in the same skb, the sendpage() path has been forgotten. We want the charging to happen for sendpage(), because pages could be coming from a pipe. What is missing is the downgrading of pure zerocopy status to make sure sk_forward_alloc will stay synced. Add tcp_downgrade_zcopy_pure() helper so that we can use it from the two callers.

2022-02-04libbpf: Fix build issue with llvm-readelfYonghong Song1-2/+2
There are cases where clang compiler is packaged in a way readelf is a symbolic link to llvm-readelf.

2022-02-04arm64: dts: qcom: sc7280: Add herobrine-r1Douglas Anderson5-2/+1647
Add the new herobrine-r1. Note that this is pretty much a re-design compared to herobrine-r0 so we don't attempt any dtsi to share stuff between them. This patch attempts to define things at 3 levels: 1. The Qcard level. Herobrine includes a Qcard PCB and the Qcard PCB is supposed to be the same (modulo stuffing options) across multiple boards, so trying to define what's there hopefully makes sense. NOTE that newer "CRD" boards from Qualcomm also use Qcard. When support for CRD3 is added hopefully it can use the Qcard include (and perhaps we should even evaluate it using herobrine.dtsi?) 2. The herobrine "baseboard" level. Right now most stuff is here with the exception of things that we _know_ will be different per board. We know that not all boards will have the same set of eMMC, nvme, and SD. We also know that the exact pin names are likely to be different. 3. The actual "board" level, AKA herobrine-rev1. NOTES: - This boots to command prompt. We're still waiting on the PWM driver. - This assumes LTE for now. Once it's clear how WiFi-only SKUs will work we expect some small changes.

Like dp_out, we should have defined edp_out in sc7280.dtsi so we don't need to do this in the board files. Like dp_hot_plug_det, we should define edp_hot_plug_det in sc7280.dtsi.

It is reasonable that in some boards the dedicated DP Hot Plug Detect will not be hooked up in favor of Type C mechanisms.

2022-02-04arm64: dts: qcom: sc7280: Clean up sdc1 / sdc2 pinctrlDouglas Anderson3-148/+133
This patch makes a few improvements to the way that sdc1 / sdc2 pinctrl is specified on sc7280: 1. There's no reason to "group" the sdc pins into one overarching node and there's a downside: we have to replicate the hierarchy in the board device tree files. Let's clean this up. 2. There's really not a lot of reason not to list the "pinctrl" for sdc1 (eMMC) in the SoC dtsi file. These aren't GPIO pins and everyone's going to specify the same pins. 3. Even though it's likely that boards will need to override pinctrl for sdc2 (SD card) to add the card detect GPIO, we can be symmetric and add it to the SoC dsti file. 4. Let's get rid of the word "on" from the normal config and add a "sleep" suffix to the sleep config. This looks cleaner to me. This is intended to be a no-op change but it could plausibly change behavior depending on how the pinctrl code parses things. One thing to note is that "SD card detect" is explicitly listed now as keeping its pull enabled in sleep since we still want to detect card insertions even if the controller is suspended (because no card is inserted). The pinctrl framework likely did this anyway, but it's nice to see it explicit.

2022-02-04selftests: fixup build warnings in pidfd / clone3 testsAxel Rasmussen3-8/+5
These are some trivial fixups, which were needed to build the tests with clang and -Werror. The following issues are fixed: - Remove various unused variables. - In child_poll_leader_exit_test, clang isn't smart enough to realize syscall(SYS_exit, 0) won't return, so it complains we never return from a non-void function. Add an extra exit(0) to appease it. - In test_pidfd_poll_leader_exit, ret may be branched on despite being uninitialized, if we have !use_waitpid. Initialize it to zero to get the right behavior in that case.

2022-02-04pidfd: fix test failure due to stack overflow on some archesAxel Rasmussen2-7/+28
When running the pidfd_fdinfo_test on arm64, it fails for me. After some digging, the reason is that the child exits due to SIGBUS, because it overflows the 1024 byte stack we've reserved for it. To fix the issue, increase the stack size to 8192 bytes (this number is somewhat arbitrary, and was arrived at through experimentation -- I kept doubling until the failure no longer occurred). Also, let's make the issue easier to debug. wait_for_pid() returns an ambiguous value: it may return -1 in all of these cases: 1. waitpid() itself returned -1 2. waitpid() returned success, but we found !WIFEXITED(status). 3. The child process exited, but it did so with a -1 exit code. There's no way for the caller to tell the difference. So, at least log which occurred, so the test runner can debug things. While debugging this, I found that we had !WIFEXITED(), because the child exited due to a signal. This seems like a reasonably common case, so also print out whether or not we have WIFSIGNALED(), and the associated WTERMSIG() (if any). This lets us see the SIGBUS I'm fixing clearly when it occurs. Finally, I'm suspicious of allocating the child's stack on our stack. man clone(2) suggests that the correct way to do this is with mmap(), and in particular by setting MAP_STACK. So, switch to doing it that way instead.

Commit b8b87fd954b4 ("selinux: Fix selinux_sb_mnt_opts_compat()") started to parse mount options into SIDs in selinux_add_opt() if policy has already been loaded. Since it's extremely unlikely that anyone would depend on the ability to set SELinux contexts on fs_context before loading the policy and then mounting that context after simplify the logic by always parsing the options early. Note that the multi-step mounting is only possible with the new fscontext mount API and wasn't possible before its introduction.
