From: Christoph Hellwig Date: Fri, 3 Jul 2020 22:15:27 +0000 (-0700) Subject: vmalloc: fix the owner argument for the new __vmalloc_node_range callers X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a3a66c3822e03692ed7c5888e8f2d384cc698d34;p=linux.git vmalloc: fix the owner argument for the new __vmalloc_node_range callers Fix the recently added new __vmalloc_node_range callers to pass the correct values as the owner for display in /proc/vmallocinfo. Fixes: 800e26b81311 ("x86/hyperv: allocate the hypercall page with only read and execute bits") Fixes: 10d5e97c1bf8 ("arm64: use PAGE_KERNEL_ROX directly in alloc_insn_page") Fixes: 7a0e27b2a0ce ("mm: remove vmalloc_exec") Reported-by: Ard Biesheuvel Signed-off-by: Christoph Hellwig Signed-off-by: Andrew Morton Link: http://lkml.kernel.org/r/20200627075649.2455097-1-hch@lst.de Signed-off-by: Linus Torvalds --- diff --git a/arch/arm64/kernel/probes/kprobes.c b/arch/arm64/kernel/probes/kprobes.c index cbe49cd117cfe..5290f17a4d804 100644 --- a/arch/arm64/kernel/probes/kprobes.c +++ b/arch/arm64/kernel/probes/kprobes.c @@ -122,7 +122,7 @@ void *alloc_insn_page(void) { return __vmalloc_node_range(PAGE_SIZE, 1, VMALLOC_START, VMALLOC_END, GFP_KERNEL, PAGE_KERNEL_ROX, VM_FLUSH_RESET_PERMS, - NUMA_NO_NODE, __func__); + NUMA_NO_NODE, __builtin_return_address(0)); } /* arm kprobe: install breakpoint in text */ diff --git a/arch/x86/hyperv/hv_init.c b/arch/x86/hyperv/hv_init.c index 2bdc72e6890ec..6035df1b49e1a 100644 --- a/arch/x86/hyperv/hv_init.c +++ b/arch/x86/hyperv/hv_init.c @@ -377,7 +377,8 @@ void __init hyperv_init(void) hv_hypercall_pg = __vmalloc_node_range(PAGE_SIZE, 1, VMALLOC_START, VMALLOC_END, GFP_KERNEL, PAGE_KERNEL_ROX, - VM_FLUSH_RESET_PERMS, NUMA_NO_NODE, __func__); + VM_FLUSH_RESET_PERMS, NUMA_NO_NODE, + __builtin_return_address(0)); if (hv_hypercall_pg == NULL) { wrmsrl(HV_X64_MSR_GUEST_OS_ID, 0); goto remove_cpuhp_state; diff --git a/kernel/module.c b/kernel/module.c index 0c6573b98c366..bee1c25ca5c5e 100644 --- a/kernel/module.c +++ b/kernel/module.c @@ -2785,7 +2785,7 @@ void * __weak module_alloc(unsigned long size) { return __vmalloc_node_range(size, 1, VMALLOC_START, VMALLOC_END, GFP_KERNEL, PAGE_KERNEL_EXEC, VM_FLUSH_RESET_PERMS, - NUMA_NO_NODE, __func__); + NUMA_NO_NODE, __builtin_return_address(0)); } bool __weak module_init_section(const char *name)
