ASN.1: Fix check for strdup() success

2023-04-26T09:21:53Z

commit 5a43001c01691dcbd396541e6faa2c0077378f48 upstream. It seems there is a misprint in the check of strdup() return code that can lead to NULL pointer dereference.

kbuild: generate modules.order only in directories visited by obj-y/m

2023-03-17T07:31:43Z

[ Upstream commit 4f2c8f3089f538f556c86f26603a062865e4aa94 ] The modules.order files in directories visited by the chain of obj-y or obj-m are merged to the upper-level ones, and become parts of the top-level modules.order. On the other hand, there is no need to generate modules.order in directories visited by subdir-y or subdir-m since they would become orphan anyway.

[ Upstream commit d9f78edfd81b9e484423534360350ef7253cc888 ] The current implementation of need-builtin is false-positive, for example, in the following Makefile: obj-m := foo/ obj-y := foo/bar/ ..., where foo/built-in.a is not required.

scripts/faddr2line: Fix regression in name resolution on ppc64le

2022-12-08T10:18:32Z

[ Upstream commit 2d77de1581bb5b470486edaf17a7d70151131afd ] Commit 1d1a0e7c5100 ("scripts/faddr2line: Fix overlapping text section failures") can cause faddr2line to fail on ppc64le on some distributions, while it works fine on other distributions. The failure can be attributed to differences in the readelf output. $ ./scripts/faddr2line vmlinux find_busiest_group+0x00 no match for find_busiest_group+0x00 On ppc64le, readelf adds the localentry tag before the symbol name on some distributions, and adds the localentry tag after the symbol name on other distributions. This problem has been discussed previously: https://lore.kernel.org/bpf/20191211160133.GB4580@calabresa/ This problem can be overcome by filtering out the localentry tags in the readelf output. Similar fixes are already present in the kernel by way of the following commits: 1fd6cee127e2 ("libbpf: Fix VERSIONED_SYM_COUNT number parsing") aa915931ac3e ("libbpf: Fix readelf output parsing for Fedora") [jpoimboe: rework commit log] Fixes: 1d1a0e7c5100 ("scripts/faddr2line: Fix overlapping text section failures") Signed-off-by: Srikar Dronamraju Acked-by: Naveen N.

cert host tools: Stop complaining about deprecated OpenSSL functions

2022-11-25T16:40:20Z

commit 6bfb56e93bcef41859c2d5ab234ffd80b691be35 upstream. OpenSSL 3.0 deprecated the OpenSSL's ENGINE API. That is as may be, but the kernel build host tools still use it.

selinux: use "grep -E" instead of "egrep"

2022-10-26T11:19:24Z

commit c969bb8dbaf2f3628927eae73e7c579a74cf1b6e upstream. The latest version of grep claims that egrep is now obsolete so the build now contains warnings that look like: egrep: warning: egrep is obsolescent; using grep -E fix this by using "grep -E" instead.

Makefile.extrawarn: Move -Wcast-function-type-strict to W=1

2022-10-26T11:19:16Z

commit 2120635108b35ecad9c59c8b44f6cbdf4f98214e upstream. We enable -Wcast-function-type globally in the kernel to warn about mismatching types in function pointer casts. Compilers currently warn only about ABI incompability with this flag, but Clang 16 will enable a stricter version of the check by default that checks for an exact type match. This will be very noisy in the kernel, so disable -Wcast-function-type-strict without W=1 until the new warnings have been addressed.

mksysmap: Fix the mismatch of 'L0' symbols in System.map

2022-09-28T09:02:53Z

[ Upstream commit c17a2538704f926ee4d167ba625e09b1040d8439 ] When System.map was generated, the kernel used mksysmap to filter the kernel symbols, we need to filter "L0" symbols in LoongArch architecture. $ cat System.map | grep L0 9000000000221540 t L0 The L0 symbol exists in System.map, but not in .tmp_System.map.

kbuild: Fix include path in scripts/Makefile.modpost

2022-09-05T08:26:33Z

commit 23a0cb8e3225122496bfa79172005c587c2d64bf upstream. When building an external module, if users don't need to separate the compilation output and source code, they run the following command: "make -C $(LINUX_SRC_DIR) M=$(PWD)". At this point, "$(KBUILD_EXTMOD)" and "$(src)" are the same. If they need to separate them, they run "make -C $(KERNEL_SRC_DIR) O=$(KERNEL_OUT_DIR) M=$(OUT_DIR) src=$(PWD)". Before running the command, they need to copy "Kbuild" or "Makefile" to "$(OUT_DIR)" to prevent compilation failure. So the kernel should change the included path to avoid the copy operation. Signed-off-by: Jing Leng [masahiro: I do not think "M=$(OUT_DIR) src=$(PWD)" is the official way, but this patch is a nice clean up anyway.] Signed-off-by: Masahiro Yamada [nsc: updated context for v4.19] Signed-off-by: Nicolas Schier Signed-off-by: Greg Kroah-Hartman
