Most of that code I did not manage to get tested and reviewed before the merge window opened but a handful of very useful cleanups are ready to be merged. The first change is simply the removal of the bdflush system call. The code has now been disabled long enough that even the oldest userspace working userspace setups anyone can find to test are fine with the bdflush system call being removed. Changing m68k fsp040_die to use force_sigsegv(SIGSEGV) instead of calling do_exit directly is interesting only in that it is nearly the most difficult of the incorrect uses of do_exit to remove.

2021-09-01parisc: fix crash with signals and allocaMikulas Patocka
I was debugging some crashes on parisc and I found out that there is a crash possibility if a function using alloca is interrupted by a signal. The reason for the crash is that the gcc alloca implementation leaves garbage in the upper 32 bits of the sp register. This normally doesn't matter (the upper bits are ignored because the PSW W-bit is clear), however the signal delivery routine in the kernel uses full 64 bits of sp and it fails with -EFAULT if the upper 32 bits are not zero. I created this program that demonstrates the problem: #include <stdlib.h> #include <unistd.h> #include <signal.h> #include <alloca.h> static __attribute__((noinline,noclone)) void aa(int *size) { void * volatile p = alloca(-*size); while (1) ; } static void handler(int sig) { write(1, "signal delivered\n", 17); _exit(0); } int main(void) { int size = -0x100; signal(SIGALRM, handler); alarm(1); aa(&size); } If you compile it with optimizations, it will crash. The "aa" function has this disassembly: 000106a0 <aa>: 106a0: 08 03 02 41 copy r3,r1 106a4: 08 1e 02 43 copy sp,r3 106a8: 6f c1 00 80 stw,ma r1,40(sp) 106ac: 37 dc 3f c1 ldo -20(sp),ret0 106b0: 0c 7c 12 90 stw ret0,8(r3) 106b4: 0f 40 10 9c ldw 0(r26),ret0 ; ret0 = 0x00000000FFFFFF00 106b8: 97 9c 00 7e subi 3f,ret0,ret0 ; ret0 = 0xFFFFFFFF0000013F 106bc: d7 80 1c 1a depwi 0,31,6,ret0 ; ret0 = 0xFFFFFFFF00000100 106c0: 0b 9e 0a 1e add,l sp,ret0,sp ; sp = 0xFFFFFFFFxxxxxxxx 106c4: e8 1f 1f f7 b,l,n 106c4 <aa+0x24>,r0 This patch fixes the bug by truncating the "usp" variable to 32 bits.

2021-09-01parisc: Fix compile failure when building 64-bit kernel nativelyMasahiro Yamada
Commit 23243c1ace9f ("arch: use cross_compiling to check whether it is a cross build or not") broke 64-bit parisc builds on 32-bit parisc systems. Helge mentioned: - 64-bit parisc userspace is not supported yet [1] - hppa gcc does not support "-m64" flag [2] That means, parisc developers working on a 32-bit parisc machine need to use hppa64-linux-gnu-gcc (cross compiler) for building the 64-bit parisc kernel. After the offending commit, gcc is used in such a case because both $(SRCARCH) and $(SUBARCH) are 'parisc', hence cross_compiling is unset. A correct way is to introduce ARCH=parisc64 because building the 64-bit parisc kernel on a 32-bit parisc system is not exactly a native build, but rather a semi-cross build.

2021-09-01HID: usbhid: Simplify code in hid_submit_ctrl()Alan Stern
This patch makes a small simplification to the code in hid_submit_ctrl(). The test for maxpacket being > 0 is unnecessary, because endpoint 0 always has a maxpacket value which is >= 8. Furthermore, endpoint 0's maxpacket value is always a power of 2, so instead of open-coding the round-to-next-multiple computation we can call the optimized round_up() routine.

2021-09-01HID: usbhid: Fix warning caused by 0-length input reportsAlan Stern
Syzbot found a warning caused by hid_submit_ctrl() submitting a control request to transfer a 0-length input report: usb 1-1: BOGUS control dir, pipe 80000280 doesn't match bRequestType a1 (The warning message is a little difficult to understand. It means that the control request claims to be for an IN transfer but this contradicts the USB spec, which requires 0-length control transfers always to be in the OUT direction.) Now, a zero-length report isn't good for anything and there's no reason for a device to have one, but the fuzzer likes to pick out these weird edge cases. In the future, perhaps we will decide to reject 0-length reports at probe time. For now, the simplest approach for avoiding these warnings is to pretend that the report actually has length 1.

2021-09-01HID: usbhid: Fix flood of "control queue full" messagesMichal Kubecek
[patch description by Alan Stern] Commit 7652dd2c5cb7 ("USB: core: Check buffer length matches wLength for control transfers") causes control URB submissions to fail if the transfer_buffer_length value disagrees with the setup packet's wLength valuel. Unfortunately, it turns out that the usbhid can trigger this failure mode when it submits a control request for an input report: It pads the transfer buffer size to a multiple of the maxpacket value but does not increase wLength correspondingly. These failures have caused problems for people using an APS UPC, in the form of a flood of log messages resembling: hid-generic 0003:051D:0002.0002: control queue full This patch fixes the problem by setting the wLength value equal to the padded transfer_buffer_length value in hid_submit_ctrl(). As a nice bonus, the code which stores the transfer_buffer_length value is now shared between the two branches of an "if" statement, so it can be de-duplicated.

2021-09-01fs: dlm: avoid comms shutdown delay in release_lockspaceAlexander Aring
When dlm_release_lockspace does active shutdown on connections to other nodes, the active shutdown will wait for any exisitng passive shutdowns to be resolved. But, the sequence of operations during dlm_release_lockspace can prevent the normal resolution of passive shutdowns (processed normally by way of lockspace recovery.) This disruption of passive shutdown handling can cause the active shutdown to wait for a full timeout period, delaying the completion of dlm_release_lockspace. To fix this, make dlm_release_lockspace resolve existing passive shutdowns (by calling dlm_clear_members earlier), before it does active shutdowns. The active shutdowns will not find any passive shutdowns to wait for, and will not be delayed.

2021-09-01powerpc/bug: Cast to unsigned long before passing to inline asmMichael Ellerman
In commit 1e688dd2a3d6 ("powerpc/bug: Provide better flexibility to WARN_ON/__WARN_FLAGS() with asm goto") we changed WARN_ON(). Previously it would take the warning condition, x, and double negate it before converting the result to int, and passing that int to the underlying inline asm. ie: #define WARN_ON(x) ({ int __ret_warn_on = !!(x); if (__builtin_constant_p(__ret_warn_on)) { ... } else { BUG_ENTRY(PPC_TLNEI " %4, 0", BUGFLAG_WARNING | BUGFLAG_TAINT(TAINT_WARN), "r" (__ret_warn_on)); The asm then does a full register width comparison with zero and traps if it is non-zero (PPC_TLNEI). The new code instead passes the full expression, x, with some arbitrary type, to the inline asm: #define WARN_ON(x) ({ ... do { if (__builtin_constant_p((x))) { ... } else { ... WARN_ENTRY(PPC_TLNEI " %4, 0", BUGFLAG_WARNING | BUGFLAG_TAINT(TAINT_WARN), __label_warn_on, "r" (x)); As reported[1] by Nathan, when building with clang this can cause spurious warnings to fire repeatedly at boot: WARNING: CPU: 0 PID: 1 at lib/klist.c:62 .klist_add_tail+0x3c/0x110 Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Tainted: G W 5.14.0-rc7-next-20210825 #1 NIP: c0000000007ff81c LR: c00000000090a038 CTR: 0000000000000000 REGS: c0000000073c32a0 TRAP: 0700 Tainted: G W (5.14.0-rc7-next-20210825) MSR: 8000000002029032 <SF,VEC,EE,ME,IR,DR,RI> CR: 22000a40 XER: 00000000 CFAR: c00000000090a034 IRQMASK: 0 GPR00: c00000000090a038 c0000000073c3540 c000000001be3200 0000000000000001 GPR04: c0000000072d65c0 0000000000000000 c0000000091ba798 c0000000091bb0a0 GPR08: 0000000000000001 0000000000000000 c000000008581918 fffffffffffffc00 GPR12: 0000000044000240 c000000001dd0000 c000000000012300 0000000000000000 GPR16: 0000000000000000 0000000000000000 0000000000000000 0000000000000000 GPR20: 0000000000000000 0000000000000000 0000000000000000 0000000000000000 GPR24: 0000000000000000 c0000000017e3200 0000000000000000 c000000001a0e778 GPR28: c0000000072d65b0 c0000000072d65a8 c000000007de72c8 c0000000073c35d0 NIP .klist_add_tail+0x3c/0x110 LR .bus_add_driver+0x148/0x290 Call Trace: 0xc0000000073c35d0 (unreliable) .bus_add_driver+0x148/0x290 .driver_register+0xb8/0x190 .__hid_register_driver+0x70/0xd0 .redragon_driver_init+0x34/0x58 .do_one_initcall+0x130/0x3b0 .do_initcall_level+0xd8/0x188 .do_initcalls+0x7c/0xdc .kernel_init_freeable+0x178/0x21c .kernel_init+0x34/0x220 .ret_from_kernel_thread+0x58/0x60 Instruction dump: fba10078 7c7d1b78 38600001 fb810070 3b9d0008 fbc10080 7c9e2378 389d0018 fb9d0008 fb9d0010 90640000 fbdd0000 <0b1e0000> e87e0018 28230000 41820024 The instruction dump shows that we are trapping because r30 is not zero: tdnei r30,0 Where r30 = c000000007de72c8 The WARN_ON() comes from: static void knode_set_klist(struct klist_node *knode, struct klist *klist) { knode->n_klist = klist; /* no knode deserves to start its life dead */ WARN_ON(knode_dead(knode)); ^^^^^^^^^^^^^^^^^ Where: #define KNODE_DEAD 1LU static bool knode_dead(struct klist_node *knode) { return (unsigned long)knode->n_klist & KNODE_DEAD; } The full disassembly shows that clang has not generated any code to apply the "& KNODE_DEAD" to the n_klist pointer, which is surprising. Nathan filed an LLVM bug [2], in which Eli Friedman explained that clang believes it is only passing a single bit to the asm (ie. a bool) and so the mask of bit 0 with 1 can be omitted, and suggested that if we want the full 64-bit value passed to the inline asm we should cast to a 64-bit type (or 32-bit on 32-bits). In fact we already do that for BUG_ENTRY(), which was added to fix a possibly similar bug in 2005 in commit 32818c2eb6b8 ("[PATCH] ppc64: Fix issue with gcc 4.0 compiled kernels"). So cast the value we pass to the inline asm to long. For GCC this appears to have no effect on code generation, other than causing sign extension in some cases.

2021-09-01xen/pcifront: Removed unnecessary __ref annotationSergio Miguéns Iglesias
An unnecessary "__ref" annotation was removed from the "drivers/pci/xen_pcifront.c" file. The function where the annotation was used was "pcifront_backend_changed()", which does not call any functions annotated as "__*init" nor "__*exit". This makes "__ref" unnecessary since this annotation is used to make the compiler ignore section miss-matches when they are not happening here in the first place. In addition to the aforementioned change, some code style issues were fixed in the same file.

Since the conversion to generic ptdump we see crashes on 64-bit: BUG: Unable to handle kernel data access on read at 0xc0eeff7f00000000 Faulting instruction address: 0xc00000000045e5fc Oops: Kernel access of bad area, sig: 11 [#1] ...

That happens because we initialised the ptdump_range to span all the way up to 0xffffffffffffffff: static struct ptdump_range ptdump_range[] __ro_after_init = { {TASK_SIZE_MAX, ~0UL}, But the kernel page tables don't span that far. So on 64-bit set the end of the range to be the address immediately past the end of the kernel page tables, to limit the page table walk to valid addresses.

2021-08-31mailbox: cmdq: add multi-gce clocks support for mt8195jason-jh.lin
For the design of GCE hardware event signal transportation, evnet rx will send the event signal to all GCE event merges after receiving the event signal from the other hardware. Because GCE event merges need to response to event rx, their clocks must be enabled at that time. To make sure all the gce clock is enabled while receiving the hardware event, each cmdq mailbox should enable or disable the others gce clk at the same time.
