[PATCH] ipc: Fix building compat mode without sysvipc

by Arnd Bergmann

As John Stultz noticed, my y2038 syscall series caused a link failure when CONFIG_SYSVIPC is enabled but CONFIG_COMPAT is enabled: arch/arm64/kernel/sys32.o:(.rodata+0x960): undefined reference to `__arm64_compat_sys_old_semctl' arch/arm64/kernel/sys32.o:(.rodata+0x980): undefined reference to `__arm64_compat_sys_old_msgctl' arch/arm64/kernel/sys32.o:(.rodata+0x9a0): undefined reference to `__arm64_compat_sys_old_shmctl' Add the missing entries in kernel/sys_ni.c for the new system calls.

[GIT PULL] y2038: additional syscall ABI cleanup

by Arnd Bergmann

The following changes since commit 48166e6ea47d23984f0b481ca199250e1ce0730a: y2038: add 64-bit time_t syscalls to all 32-bit architectures (2019-02-07 00:13:28 +0100) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git tags/y2038-syscall-abi for you to fetch changes up to d4c08b9776b392e20efc6198ebe1bc8ec1911d9b: riscv: Use latest system call ABI (2019-02-25 20:53:52 +0100) ---------------------------------------------------------------- y2038: additional syscall ABI cleanup This is a follow-up to the y2038 syscall patches already merged in the tip tree. As the final 32-bit RISC-V syscall ABI is still being decided on, this is the last chance to make a few corrections to leave out interfaces based on 32-bit time_t along with the old off_t and rlimit types. The series achieves this in a few steps: - A couple of bug fixes for minor regressions I introduced in the original series - A couple of older patches from Yury Norov that I had never merged in the past, these fix up the openat/open_by_handle_at and getrlimit/setrlimit syscalls to disallow the old versions of off_t and rlimit. - Hiding the deprecated system calls behind an #ifdef in include/uapi/asm-generic/unistd.h - Change arch/riscv to drop all these ABIs.

[PATCH 0/8] y2038: remove time32 ABI on rv32 and csky

by Arnd Bergmann

This is a follow-up to the y2038 syscall patches that Thomas already merged. Both the csky and riscv maintainers have requested that the time_t syscall ABI should be completely converted before an official glibc port is merged. The series achieves this in a few steps: - A couple of bug fixes for minor regressions I introduced in the original series - A couple of older patches from Yury Norov that I had never merged in the past, these fix up the openat/open_by_handle_at and getrlimit/setrlimit syscalls to disallow the old versions of off_t and rlimit. - Hiding the deprecated system calls behind an #ifdef in include/uapi/asm-generic/unistd.h - Changing the two architectures to use the new style syscall ABI for all three types: loff_t, rusage, and time_t.

[PATCH net-next 0/2] uapi: Add a new header for time types

by Deepa Dinamani

The series aims at adding a new time header: time_types.h. This header is what will eventually hold all the uapi time types that we plan to leave across the interfaces after the y2038 cleanup. The series was discussed with Arnd Bergmann. The second patch fixes the errqueue.h header, which has a dependency on these types. Note that there may be a trivial merge conflict with linux-next c70a772fda11 ("y2038: remove struct definition redirects").

[PATCH net-next v5 00/12] net: y2038-safe socket timestamps

by Deepa Dinamani

The series introduces new socket timestamps that are y2038 safe. The time data types used for the existing socket timestamp options: SO_TIMESTAMP, SO_TIMESTAMPNS and SO_TIMESTAMPING are not y2038 safe. The series introduces SO_TIMESTAMP_NEW, SO_TIMESTAMPNS_NEW and SO_TIMESTAMPING_NEW to replace these. These new timestamps can be used on all architectures. The alternative considered was to extend the sys_setsockopt() by using the flags. We did not receive any strong opinions about either of the approaches. Hence, this was chosen, as glibc folks preferred this. The series does not deal with updating the internal kernel socket calls like rxrpc to make them y2038 safe. This will be dealt with separately. Note that the timestamps behavior already does not match the man page specific behavior: SIOCGSTAMP This ioctl should only be used if the socket option SO_TIMESTAMP is not set on the socket. Otherwise, it returns the timestamp of the last packet that was received while SO_TIMESTAMP was not set, or it fails if no such packet has been received, (i.e., ioctl(2) returns -1 with errno set to ENOENT). The recommendation is to update the man page to remove the above statement. The overview of the socket timestamp series is as below: 1. Delete asm specific socket.h when possible. 2. Support SO/SCM_TIMESTAMP* options only in userspace. 3. Rename current SO/SCM_TIMESTAMP* to SO/SCM_TIMESTAMP*_OLD. 3. Alter socket options so that SOCK_RCVTSTAMPNS does not rely on SOCK_RCVTSTAMP. 4. Introduce y2038 safe types for socket timestamp. 5. Introduce new y2038 safe socket options SO/SCM_TIMESTAMP*_NEW. 6. Intorduce new y2038 safe socket timeout options. Changes since v4: * Fixed the typo in calling sock_get_timeout() Changes since v3: * Rebased onto net-next and fixups as per review comments * Merged the socket timeout series * Integrated Arnd's patch to simplify compat handling of timeout syscalls Changes since v2: * Removed extra functions to reduce diff churn as per code review Changes since v1: * Dropped the change to disentangle sock flags * Renamed sock_timeval to __kernel_sock_timeval * Updated a few comments * Added documentation changes Arnd Bergmann (1): socket: move compat timeout handling into sock.c Deepa Dinamani (11): selftests: add missing include unistd arch: Use asm-generic/socket.h when possible sockopt: Rename SO_TIMESTAMP* to SO_TIMESTAMP*_OLD arch: sparc: Override struct __kernel_old_timeval socket: Use old_timeval types for socket timestamps socket: Add struct __kernel_sock_timeval socket: Add SO_TIMESTAMP[NS]_NEW socket: Add SO_TIMESTAMPING_NEW socket: Update timestamping Documentation socket: Rename SO_RCVTIMEO/ SO_SNDTIMEO with _OLD suffixes sock: Add SO_RCVTIMEO_NEW and SO_SNDTIMEO_NEW Documentation/networking/timestamping.txt | 43 ++++- arch/alpha/include/uapi/asm/socket.h | 47 ++++-- arch/ia64/include/uapi/asm/Kbuild | 1 + arch/ia64/include/uapi/asm/socket.h | 122 -------------- arch/mips/include/uapi/asm/socket.h | 47 ++++-- arch/parisc/include/uapi/asm/socket.h | 46 ++++-- arch/powerpc/include/uapi/asm/socket.h | 4 +- arch/s390/include/uapi/asm/Kbuild | 1 + arch/s390/include/uapi/asm/socket.h | 119 -------------- arch/sparc/include/uapi/asm/posix_types.h | 10 ++ arch/sparc/include/uapi/asm/socket.h | 49 ++++-- arch/x86/include/uapi/asm/Kbuild | 1 + arch/x86/include/uapi/asm/socket.h | 1 - arch/xtensa/include/asm/Kbuild | 1 + arch/xtensa/include/uapi/asm/Kbuild | 1 + arch/xtensa/include/uapi/asm/socket.h | 124 -------------- drivers/isdn/mISDN/socket.c | 2 +- fs/dlm/lowcomms.c | 4 +- include/linux/skbuff.h | 24 ++- include/linux/socket.h | 8 + include/net/sock.h | 1 + include/uapi/asm-generic/socket.h | 48 ++++-- include/uapi/linux/errqueue.h | 4 + include/uapi/linux/time.h | 7 + net/bluetooth/hci_sock.c | 4 +- net/compat.c | 78 +-------- net/core/scm.c | 27 ++++ net/core/sock.c | 151 +++++++++++++----- net/ipv4/tcp.c | 61 ++++--- net/rds/af_rds.c | 10 +- net/rds/recv.c | 18 ++- net/rxrpc/local_object.c | 2 +- net/smc/af_smc.c | 3 +- net/socket.c | 50 ++++-- net/vmw_vsock/af_vsock.c | 4 +- .../networking/timestamping/rxtimestamp.c | 1 + 36 files changed, 541 insertions(+), 583 deletions(-) delete mode 100644 arch/ia64/include/uapi/asm/socket.h delete mode 100644 arch/s390/include/uapi/asm/socket.h delete mode 100644 arch/x86/include/uapi/asm/socket.h delete mode 100644 arch/xtensa/include/uapi/asm/socket.h -- 2.17.1 Cc: ccaulfie(a)redhat.com Cc: chris(a)zankel.net Cc: cluster-devel(a)redhat.com Cc: davem(a)davemloft.net Cc: deller(a)gmx.de Cc: dhowells(a)redhat.com Cc: fenghua.yu(a)intel.com Cc: isdn(a)linux-pingi.de Cc: jejb(a)parisc-linux.org Cc: linux-afs(a)lists.infradead.org Cc: linux-alpha(a)vger.kernel.org Cc: linux-arch(a)vger.kernel.org Cc: linux-ia64(a)vger.kernel.org Cc: linux-mips(a)linux-mips.org Cc: linux-mips(a)vger.kernel.org Cc: linux-parisc(a)vger.kernel.org Cc: linuxppc-dev(a)lists.ozlabs.org Cc: linux-rdma(a)vger.kernel.org Cc: linux-s390(a)vger.kernel.org Cc: linux-xtensa(a)linux-xtensa.org Cc: netdev(a)vger.kernel.org Cc: paulus(a)samba.org Cc: ralf(a)linux-mips.org Cc: rth(a)twiddle.net Cc: schwidefsky(a)de.ibm.com Cc: sparclinux(a)vger.kernel.org Cc: tglx(a)linutronix.de Cc: ubraun(a)linux.ibm.com

[GIT PULL 1/2] arch: System call unification and cleanup

by Arnd Bergmann

The following changes since commit 1c7fc5cbc33980acd13d668f1c8f0313d6ae9fd8: Linux 5.0-rc2 (2019-01-14 10:41:12 +1200) are available in the Git repository at: git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground.git tags/y2038-syscall-cleanup for you to fetch changes up to 805089c2f77047d81f47ddc227435d606ceb180e: syscalls: remove obsolete __IGNORE_ macros (2019-02-07 00:13:27 +0100) ---------------------------------------------------------------- arch: System call unification and cleanup The system call tables have diverged a bit over the years, and a number of the recent additions never made it into all architectures, for one reason or another. This is an attempt to clean it up as far as we can without breaking compatibility, doing a number of steps: - Add system calls that have not yet been integrated into all architectures but that we definitely want there. This includes {,f}statfs64() and get{eg,eu,g,p,u,pp}id() on alpha, which have been missing traditionally. - The s390 compat syscall handling is cleaned up to be more like what we do on other architectures, while keeping the 31-bit pointer extension. This was merged as a shared branch by the s390 maintainers and is included here in order to base the other patches on top. - Add the separate ipc syscalls on all architectures that traditionally only had sys_ipc(). This version is done without support for IPC_OLD that is we have in sys_ipc. The new semtimedop_time64 syscall will only be added here, not in sys_ipc - Add syscall numbers for a couple of syscalls that we probably don't need everywhere, in particular pkey_* and rseq, for the purpose of symmetry: if it's in asm-generic/unistd.h, it makes sense to have it everywhere. I expect that any future system calls will get assigned on all platforms together, even when they appear to be specific to a single architecture. - Prepare for having the same system call numbers for any future calls. In combination with the generated tables, this hopefully makes it easier to add new calls across all architectures together. All of the above are technically separate from the y2038 work, but are done as preparation before we add the new 64-bit time_t system calls everywhere, providing a common baseline set of system calls. I expect that glibc and other libraries that want to use 64-bit time_t will require linux-5.1 kernel headers for building in the future, and at a much later point may also require linux-5.1 or a later version as the minimum kernel at runtime. Having a common baseline then allows the removal of many architecture or kernel version specific workarounds.
