[PATCH v5] spi: spi-mem: Adjust op len based on message/transfer size limitations

by Chuanhua Han

We need that to adjust the len of the 2nd transfer (called data in spi-mem) if it's too long to fit in a SPI message or SPI transfer. Fixes: c36ff266dc82 ("spi: Extend the core to ease integration of SPI memory controllers") Cc: <stable(a)vger.kernel.org> Signed-off-by: Chuanhua Han <chuanhua.han(a)nxp.com> Reviewed-by: Boris Brezillon <boris.brezillon(a)bootlin.com> --- Changes in v5: -Add the validation check after the op->data.nbytes assignment -Assign the "len" variable after defining it -Remove the brackets on both sides of "opt-> data.nbytes" Changes in v4: -Rename variable name "opcode_addr_dummy_sum" to "len" -The comparison of "spi_max_message_size(mem->spi)" and "len" was removed -Adjust their order when comparing the sizes of "spi_max_message_size(mem->spi)" and "len" -Changing the "unsigned long" type in the code to "size_t" Changes in v3: -Rename variable name "val" to "opcode_addr_dummy_sum" -Place the legitimacy of the transfer size(i.e., "spi_max_message_size(mem->spi)" and "opcode_addr_dummy_sum") into "if (! ctlr - > mem_ops | |! ctlr-> mem_ops->exec_op) {" structure and add "spi_max_transfer_size(mem->spi) and opcode_addr_dummy_sum" -Adjust the formatting alignment of the code -"(unsigned long)op->data.nbytes" was modified to "(unsigned long)(op->data.nbytes)" Changes in v2: -Place the adjusted transfer bytes code in spi_mem_adjust_op_size() and check spi_max_message_size(mem->spi) value before subtracting opcode, addr and dummy bytes -Change the code from fsl-espi controller to generic code(The adjustment of spi transmission length was originally modified in the "drivers/spi/spi-fsl-espi.c" file, and now the adjustment of transfer length is made in the "drivers/spi/spi-mem.c" file) drivers/spi/spi-mem.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/drivers/spi/spi-mem.c b/drivers/spi/spi-mem.c index e43842c..eb72dba 100644 --- a/drivers/spi/spi-mem.c +++ b/drivers/spi/spi-mem.c @@ -346,10 +346,25 @@ EXPORT_SYMBOL_GPL(spi_mem_get_name); int spi_mem_adjust_op_size(struct spi_mem *mem, struct spi_mem_op *op) { struct spi_controller *ctlr = mem->spi->controller; + size_t len; + + len = sizeof(op->cmd.opcode) + op->addr.nbytes + op->dummy.nbytes; if (ctlr->mem_ops && ctlr->mem_ops->adjust_op_size) return ctlr->mem_ops->adjust_op_size(mem, op); + if (!ctlr->mem_ops || !ctlr->mem_ops->exec_op) { + if (len > spi_max_transfer_size(mem->spi)) + return -EINVAL; + + op->data.nbytes = min3((size_t)op->data.nbytes, + spi_max_transfer_size(mem->spi), + spi_max_message_size(mem->spi) - + len); + if (!op->data.nbytes) + return -EINVAL; + } + return 0; } EXPORT_SYMBOL_GPL(spi_mem_adjust_op_size); -- 2.7.4

[tip:perf/urgent] perf/core: Force USER_DS when recording user stack data

If this happens under set_fs(KERNEL_DS), then we end up reading user stack data using __copy_from_user_inatomic() under set_fs(KERNEL_DS). I think this conflicts with the intention of using set_fs(KERNEL_DS). And it is explicitly forbidden by hardware on ARM64 when both CONFIG_ARM64_UAO and CONFIG_ARM64_PAN are used. So fix this by forcing USER_DS when recording user stack data.

[PATCH AUTOSEL 4.18 001/131] tc-testing: flush gact actions on test teardown

by Sasha Levin

From: Vlad Buslov <vladbu(a)mellanox.com> [ Upstream commit 0c62f8a820b7fdeacf5ad9f9e24b53043d372c97 ] Test 6fb4 creates one mirred and one pipe action, but only flushes mirred on teardown.

[PATCH] ALSA: bebob: use address returned by kmalloc() instead of kernel stack for streaming DMA mapping

by Takashi Sakamoto

When executing 'fw_run_transaction()' with 'TCODE_WRITE_BLOCK_REQUEST', an address of 'payload' argument is used for streaming DMA mapping by 'firewire_ohci' module if 'size' argument is larger than 8 byte. Although in this case the address should not be on kernel stack, current implementation of ALSA bebob driver uses data in kernel stack for a cue to boot M-Audio devices. This often brings unexpected result, especially for a case of CONFIG_VMAP_STACK=y. This commit fixes the bug.

[PATCH net 01/13] net: sched: cls_u32: fix hnode refcounting

by Al Viro

From: Al Viro <viro(a)zeniv.linux.org.uk> cls_u32.c misuses refcounts for struct tc_u_hnode - it counts references via ->hlist and via ->tp_root together. u32_destroy() drops the former and, in case when there had been links, leaves the sucker on the list. As the result, there's nothing to protect it from getting freed once links are dropped. That also makes the "is it busy" check incapable of catching the root hnode - it *is* busy (there's a reference from tp), but we don't see it as something separate. "Is it our root?" check partially covers that, but the problem exists for others' roots as well. AFAICS, the minimal fix preserving the existing behaviour (where it doesn't include oopsen, that is) would be this: * count tp->root and tp_c->hlist as separate references. I.e. have u32_init() set refcount to 2, not 1. * in u32_destroy() we always drop the former; in u32_destroy_hnode() - the latter. That way we have *all* references contributing to refcount. List removal happens in u32_destroy_hnode() (called only when ->refcnt is 1) an in u32_destroy() in case of tc_u_common going away, along with everything reachable from it. IOW, that way we know that u32_destroy_key() won't free something still on the list (or pointed to by someone's ->root).

[PATCH 1/7] fix hnode refcounting

by Al Viro

From: Al Viro <viro(a)zeniv.linux.org.uk> cls_u32.c misuses refcounts for struct tc_u_hnode - it counts references via ->hlist and via ->tp_root together. u32_destroy() drops the former and, in case when there had been links, leaves the sucker on the list. As the result, there's nothing to protect it from getting freed once links are dropped. That also makes the "is it busy" check incapable of catching the root hnode - it *is* busy (there's a reference from tp), but we don't see it as something separate. "Is it our root?" check partially covers that, but the problem exists for others' roots as well. AFAICS, the minimal fix preserving the existing behaviour (where it doesn't include oopsen, that is) would be this: * count tp->root and tp_c->hlist as separate references. I.e. have u32_init() set refcount to 2, not 1. * in u32_destroy() we always drop the former; in u32_destroy_hnode() - the latter. That way we have *all* references contributing to refcount. List removal happens in u32_destroy_hnode() (called only when ->refcnt is 1) an in u32_destroy() in case of tc_u_common going away, along with everything reachable from it. IOW, that way we know that u32_destroy_key() won't free something still on the list (or pointed to by someone's ->root).

[PATCH] xen/netfront: fix waiting for xenbus state change

by Juergen Gross

Commit 822fb18a82aba ("xen-netfront: wait xenbus state change when load module manually") added a new wait queue to wait on for a state change when the module is loaded manually. Unfortunately there is no wakeup anywhere to stop that waiting. Instead of introducing a new wait queue rename the existing module_unload_q to module_wq and use it for both purposes (loading and unloading). As any state change of the backend might be intended to stop waiting do the wake_up_all() in any case when netback_changed() is called.

This would trigger when performing "perf" with a high NMI interrupt rate, while enabling and disabling function tracer. Ftrace uses breakpoints to convert the nops at the start of functions to calls to the function trampolines. The breakpoint traps disable interrupts and this makes calls into lockdep via the trace_hardirqs_off_thunk in the entry.S code. What happens is the following: do_idle { [interrupts enabled] <interrupt> [interrupts disabled] TRACE_IRQS_OFF [lockdep says irqs off] [...] TRACE_IRQS_IRET test if pt_regs say return to interrupts enabled [yes] TRACE_IRQS_ON [lockdep says irqs are on] <nmi> nmi_enter() { printk_nmi_enter() [traced by ftrace] [ hit ftrace breakpoint ] <breakpoint exception> TRACE_IRQS_OFF [lockdep says irqs off] [...] TRACE_IRQS_IRET [return from breakpoint] test if pt_regs say interrupts enabled [no] [iret back to interrupt] [iret back to code] tick_nohz_idle_enter() { lockdep_assert_irqs_enabled() [lockdep say no!] Although interrupts are indeed enabled, lockdep thinks it is not, and since we now do asserts via lockdep, it gives a false warning. The issue here is that printk_nmi_enter() is called before lockdep_off(), which disables lockdep (for this reason) in NMIs. By simply not allowing ftrace to see printk_nmi_enter() (via notrace annotation) we keep lockdep from getting confused.

[PULL RESEND v2 2/4] arm64: KVM: Only force FPEXC32_EL2.EN if trapping FPSIMD

by Christoffer Dall

From: Marc Zyngier <marc.zyngier(a)arm.com> If trapping FPSIMD in the context of an AArch32 guest, it is critical to set FPEXC32_EL2.EN to 1 so that the trapping is taken to EL2 and not EL1. Conversely, it is just as critical *not* to set FPEXC32_EL2.EN to 1 if we're not going to trap FPSIMD, as we then corrupt the existing VFP state. Moving the call to __activate_traps_fpsimd32 to the point where we know for sure that we are going to trap ensures that we don't set that bit spuriously.

[PULL RESEND v2 1/4] KVM: arm/arm64: Clean dcache to PoC when changing PTE due to CoW

by Christoffer Dall

From: Marc Zyngier <marc.zyngier(a)arm.com> When triggering a CoW, we unmap the RO page via an MMU notifier (invalidate_range_start), and then populate the new PTE using another one (change_pte). In the meantime, we'll have copied the old page into the new one. The problem is that the data for the new page is sitting in the cache, and should the guest have an uncached mapping to that page (or its MMU off), following accesses will bypass the cache. In a way, this is similar to what happens on a translation fault: We need to clean the page to the PoC before mapping it. So let's just do that. This fixes a KVM unit test regression observed on a HiSilicon platform, and subsequently reproduced on Seattle.

[PATCH 4/6] drm/i915: Handle incomplete Z_FINISH for compressed error states

by Chris Wilson

The final call to zlib_deflate(Z_FINISH) may require more output space to be allocated and so needs to re-invoked. Failure to do so in the current code leads to incomplete zlib streams (albeit intact due to the use of Z_SYNC_FLUSH) resulting in the occasional short object capture.
