Dear All, This is the fourth iteration of Marcin Niesluchowski's serie of patches extending kmsg interface with ability to dynamically create (and destroy) kmsg-like devices which can be used by userspace for logging. In this iteration, problems spotted by kbuild test robot are addressed. Also problem with inproper use of copy_from_user() spotted by Arnd Bergmanns is fixed (Thanks Arnd!). I would like to apologize to Richard for omitting him in the CC. This was unintended. I do realise that there is a strong movement against putting into kernel things that could be done in userpsace, however a large number of diverse environments in which Linux can operate entails greater flexibility in our perception of what should be in userspace and what should be (carefully) embraced by the kernel. Best regards, Paul Marcin Niesluchowski (7): printk: add one function for storing log in proper format kmsg: introduce additional kmsg devices support kmsg: add additional buffers support to memory class kmsg: add function for adding and deleting additional buffers kmsg: add ioctl for adding and deleting kmsg* devices kmsg: add ioctl for kmsg* devices operating on buffers kmsg: add predefined _PID, _TID, _COMM keywords to kmsg* log dict Paul Osmialowski (2): printk: extract kmsg-related routines from printk.c to kmsg.c kmsg: selftests Documentation/ioctl/ioctl-number.txt | 1 + drivers/char/mem.c | 27 +- fs/proc/kmsg.c | 4 +- include/linux/printk.h | 48 + include/uapi/linux/Kbuild | 1 + include/uapi/linux/kmsg_ioctl.h | 45 + kernel/printk/Makefile | 1 + kernel/printk/kmsg.c | 1054 +++++++++++++++++ kernel/printk/printk.c | 1251 +++++--------------- kernel/printk/printk.h | 256 ++++ samples/kmsg/kmsg-api.h | 44 + tools/testing/selftests/Makefile | 1 + tools/testing/selftests/kmsg/.gitignore | 1 + tools/testing/selftests/kmsg/Makefile | 30 + tools/testing/selftests/kmsg/kmsg-test.c | 329 +++++ tools/testing/selftests/kmsg/kmsg-test.h | 34 + tools/testing/selftests/kmsg/test-buffer-add-del.c | 76 ++ .../kmsg/test-buffer-add-write-read-del.c | 161 +++ .../kmsg/test-buffer-buf-multithreaded-torture.c | 199 ++++ .../selftests/kmsg/test-buffer-buf-torture.c | 139 +++ 20 files changed, 2737 insertions(+), 965 deletions(-) create mode 100644 include/uapi/linux/kmsg_ioctl.h create mode 100644 kernel/printk/kmsg.c create mode 100644 kernel/printk/printk.h create mode 100644 samples/kmsg/kmsg-api.h create mode 100644 tools/testing/selftests/kmsg/.gitignore create mode 100644 tools/testing/selftests/kmsg/Makefile create mode 100644 tools/testing/selftests/kmsg/kmsg-test.c create mode 100644 tools/testing/selftests/kmsg/kmsg-test.h create mode 100644 tools/testing/selftests/kmsg/test-buffer-add-del.c create mode 100644 tools/testing/selftests/kmsg/test-buffer-add-write-read-del.c create mode 100644 tools/testing/selftests/kmsg/test-buffer-buf-multithreaded-torture.c create mode 100644 tools/testing/selftests/kmsg/test-buffer-buf-torture.c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
