* linux-user: avoid using glibc internals in _syscall5 and in definition of ↵Natanael Copa2014-05-021-1/+15
| | | | | | | | | | | | | | | | target_sigevent struct Use the public sigset_t instead of the glibc specific internal __sigset_t in _syscall. Calculate the sigevent pad size is calculated in similar way as kernel does it instead of using glibc internal field _pad. This is needed for building with musl libc.

| | | | | | | | | Implement the capget and capset syscalls. This is useful because simple programs like 'ls' try to use it in AArch64, and otherwise we emit a lot of noise about it being unimplemented.

* linux-user: Implement sendmmsg syscallAlexander Graf2014-03-031-0/+4
| | | | | | | | | | | | | | | | | | | | | | Glibc when built for newer kernels assumes that the sendmmsg syscall is available. Without it, dns resolution simply fails to work. Wrap the syscall with existing infrastructure so that we don't have a host dependency on sendmmsg. To avoid locking the same area of guest memory twice (which will break if DEBUG_REMAP is defined) we pull the lock/unlock part of do_sendrecvmsg() out into its own function so the actual implementation can be shared. Signed-off-by: Alexander Graf <agraf@suse.de> [PMM: add recvmmsg support; handle errors (which also implies support for non-blocking operations); cap the vector length as the kernel implementation does; don't lock guest memory twice; support MSG_WAITFORONE flag] Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Riku Voipio <riku.voipio@linaro.org> Reviewed-by: Richard Henderson <rth@twiddle.net>

* linux-user: Fix epoll on ARM hostsAlexander Graf2013-07-231-1/+4
| | | | | | | | | | | | | | The epoll emulation uses data structures without packing them, so the compiler might choose to add padding inside. This patch makes the most offending one (target_epoll_event) a packed structure to make sure we don't pad it by accident. ARM would pad it, so declare the padding mandatory for ARM targets. This fixes i386-on-ARM epoll emulation for me. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
* linux-user: Fix target_stat and target_stat64 for OpenRISCPeter Maydell2013-07-231-12/+37
| | | | | | | | | | | | | | OpenRISC uses the asm-generic versions of target_stat and target_stat64, but it was incorrectly using the x86/ARM/etc version due to a misplaced defined(TARGET_OPENRISC). The previously unused OpenRISC section of the ifdef ladder also defined an incorrect target_stat and omitted the target_stat64 definition. Fix target_stat, provide target_stat64, and add a comment noting that these are the asm-generic versions for the benefit of future ports.
