c6640d46 - samples: add a mountinfo program to demonstrate statmount()/listmount()

Fri, 15 Nov 2024 15:35:52 +0000

samples: add a mountinfo program to demonstrate statmount()/listmount()Add a new "mountinfo" sample userland program that demonstrates how touse statmount() and listmount() to get at the same info that/proc/pid/mountinfo provides.The output of the program tries to mimic the mountinfo procfilecontents. With the -p flag, it can be pointed at an arbitrary pid toprint out info about its mount namespace. With the -r flag it willattempt to walk all of the namespaces under the pid's mount namespaceand dump out mount info from all of them.Signed-off-by: Jeff Layton Link: https://lore.kernel.org/r/20241115-statmount-v2-1-cd29aeff9cbb@kernel.orgSigned-off-by: Christian Brauner List of files: /linux-6.15/samples/vfs/Makefile

faabed29 - kbuild: introduce hostprogs-always-y and userprogs-always-y

Sat, 01 Aug 2020 12:27:18 +0000

kbuild: introduce hostprogs-always-y and userprogs-always-yTo build host programs, you need to add the program names to 'hostprogs'to use the necessary build rule, but it is not enough to build thembecause there is no dependency.There are two types of host programs: built as the prerequisite ofanother (e.g. gen_crc32table in lib/Makefile), or always built whenKbuild visits the Makefile (e.g. genksyms in scripts/genksyms/Makefile).The latter is typical in Makefiles under scripts/, which contains hostprograms globally used during the kernel build. To build them, you needto add them to both 'hostprogs' and 'always-y'.This commit adds hostprogs-always-y as a shorthand.The same applies to user programs. net/bpfilter/Makefile buildsbpfilter_umh on demand, hence always-y is unneeded. In contrast,programs under samples/ are added to both 'userprogs' and 'always-y'so they are always built when Kbuild visits the Makefiles.userprogs-always-y works as a shorthand.Signed-off-by: Masahiro Yamada Acked-by: Miguel Ojeda List of files: /linux-6.15/samples/vfs/Makefile

28949b84 - samples: vfs: build sample programs for target architecture

Wed, 29 Apr 2020 03:45:22 +0000

samples: vfs: build sample programs for target architectureThese userspace programs include UAPI headers exported to usr/include/.'make headers' always works for the target architecture (i.e. the samearchitecture as the kernel), so the sample programs should be built forthe target as well. Kbuild now supports 'userprogs' for that.I also guarded the CONFIG option by 'depends on CC_CAN_LINK' because$(CC) may not provide libc.Signed-off-by: Masahiro Yamada Acked-by: Sam Ravnborg List of files: /linux-6.15/samples/vfs/Makefile

5f2fb52f - kbuild: rename hostprogs-y/always to hostprogs/always-y

Sat, 01 Feb 2020 16:49:24 +0000

kbuild: rename hostprogs-y/always to hostprogs/always-yIn old days, the "host-progs" syntax was used for specifying hostprograms. It was renamed to the current "hostprogs-y" in 2004.It is typically useful in scripts/Makefile because it allows Kbuild toselectively compile host programs based on the kernel configuration.This commit renames like follows: always -> always-y hostprogs-y -> hostprogsSo, scripts/Makefile will look like this: always-$(CONFIG_BUILD_BIN2C) += ... always-$(CONFIG_KALLSYMS) += ... ... hostprogs := $(always-y) $(always-m)I think this makes more sense because a host program is always a hostprogram, irrespective of the kernel configuration. We want to specifywhich ones to compile by CONFIG options, so always-y will be handier.The "always", "hostprogs-y", "hostprogs-m" will be kept for backwardcompatibility for a while.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/samples/vfs/Makefile

samples: guard sub-directories with CONFIG optionsDo not descend to sub-directories when unneeded.I used subdir-$(CONFIG_...) for hidraw, seccomp, and vfs becausethey only contain host programs.While we are here, let's add SPDX License tag, and sort the directoriesalphabetically.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/samples/vfs/Makefile
