sparc: move struct termio to asm/termios.h

2024-06-16T11:23:45Z

commit c32d18e7942d7589b62e301eb426b32623366565 upstream. Every other arch declares struct termio in asm/termios.h, so make sparc match them. Resolves a build failure in the PPP software package, which includes both bits/ioctl-types.h via sys/ioctl.h (glibc) and asm/termbits.h.

sparc32: fix struct ipc64_perm type definition

2020-02-11T12:33:52Z

[ Upstream commit 34ca70ef7d3a9fa7e89151597db5e37ae1d429b4 ] As discussed in the strace issue tracker, it appears that the sparc32 sysvipc support has been broken for the past 11 years. It was however working in compat mode, which is how it must have escaped most of the regular testing. The problem is that a cleanup patch inadvertently changed the uid/gid fields in struct ipc64_perm from 32-bit types to 16-bit types in uapi headers. Both glibc and uclibc-ng still use the original types, so they should work fine with compat mode, but not natively. Change the definitions to use __kernel_uid32_t and __kernel_gid32_t again.

net: Add a new socket option for a future transmit time.

2018-07-04T13:30:27Z

This patch introduces SO_TXTIME. User space enables this option in order to pass a desired future transmit time in a CMSG when calling sendmsg(2). The argument to this socket option is a 8-bytes long struct provided by the uapi header net_tstamp.h defined as: struct sock_txtime { clockid_t clockid; u32 flags; }; Note that new fields were added to struct sock by filling a 2-bytes hole found in the struct. For that reason, neither the struct size or number of cachelines were altered. Signed-off-by: Richard Cochran Signed-off-by: Jesus Sanchez-Palencia Signed-off-by: David S. Miller

Pull siginfo updates from Eric Biederman: "This set of changes close the known issues with setting si_code to an invalid value, and with not fully initializing struct siginfo. There remains work to do on nds32, arc, unicore32, powerpc, arm, arm64, ia64 and x86 to get the code that generates siginfo into a simpler and more maintainable state. Most of that work involves refactoring the signal handling code and thus careful code review. Also not included is the work to shrink the in kernel version of struct siginfo. That depends on getting the number of places that directly manipulate struct siginfo under control, as it requires the introduction of struct kernel_siginfo for the in kernel things. Overall this set of changes looks like it is making good progress, and with a little luck I will be wrapping up the siginfo work next development cycle" * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (46 commits) signal/sh: Stop gcc warning about an impossible case in do_divide_error signal/mips: Report FPE_FLTUNK for undiagnosed floating point exceptions signal/um: More carefully relay signals in relay_signal. signal: Extend siginfo_layout with SIL_FAULT_{MCEERR|BNDERR|PKUERR} signal: Remove unncessary #ifdef SEGV_PKUERR in 32bit compat code signal/signalfd: Add support for SIGSYS signal/signalfd: Remove __put_user from signalfd_copyinfo signal/xtensa: Use force_sig_fault where appropriate signal/xtensa: Consistenly use SIGBUS in do_unaligned_user signal/um: Use force_sig_fault where appropriate signal/sparc: Use force_sig_fault where appropriate signal/sparc: Use send_sig_fault where appropriate signal/sh: Use force_sig_fault where appropriate signal/s390: Use force_sig_fault where appropriate signal/riscv: Replace do_trap_siginfo with force_sig_fault signal/riscv: Use force_sig_fault where appropriate signal/parisc: Use force_sig_fault where appropriate signal/parisc: Use force_sig_mceerr where appropriate signal/openrisc: Use force_sig_fault where appropriate signal/nios2: Use force_sig_fault where appropriate ...

y2038: sparc: Extend sysvipc data structures

2018-04-20T14:20:10Z

sparc, uses a nonstandard variation of the generic sysvipc data structures, intended to have the padding moved around so it can deal with big-endian 32-bit user space that has 64-bit time_t. Unlike most architectures, sparc actually succeeded in defining this right for big-endian CPUs, but as everyone else got it wrong, we just use the same hack everywhere. This takes just take the same approach here that we have for the asm-generic headers and adds separate 32-bit fields for the upper halves of the timestamps, to let libc deal with the mess in user space.
