2021-12-02add prlimit64(2) syscall to COMPAT_LINUX and COMPAT_LINUX32ryo
2021-11-30- uname should return "aarch64" or "aarch64_be" instead of "evbarm".ryo
- define LINUX_LARGEFILE64 to use rlimit instead of orlimit.
2021-11-26The internal architecture name of golang is "arm" or "arm64", which hasryo
different naming conventions from netbsd's machine[] or machine_arch[] ("earmv7", "aarch64", etc.) and cannot be used as is. Instead, use define LINUX_GO_RT0_SIGNATURE_ARCH{32,64}.
2021-11-26- LINUX_GO_RT0_SIGNATURE for compat_linux is no longer enabled by default.ryo
it is now defined in each arch same as the other *_SIGNATURE definitions. - add new LINUX32_GO_RT0_SIGNATURE for compat_linux32, and is defined in amd64 and aarch64.
2021-11-25add support COMPAT_LINUX32 for aarch64ryo

2021-11-25add statx(2) syscall entryryo
2021-11-25- Add compat_linux statx(2) syscall.ryo
- The AT_EMPTY_PATH processing from the modification of sys/compat/linux/common/linux_file64.c r1.63 has been separated, and made common to linux_statat(), so that it can be used not only by linux32_sys_fstatat64() but also by other *statat() variants.
2021-11-25rename bsd_to_linux_stat() to bsd_to_linux_stat64() to avoid confusion.ryo
There is a static function with the same name in linux/common/linux_file.c. NFC.

These ioctls were declared in linux_termios.h but were not actually handled.
2021-11-01Use "stack_t" instead of "struct sigaltstack", as the former is thethorpej
newer standardized name. NFC.
2021-10-27Use __SIGTRAMP_SIGCODE_VERSION rather than hard-coding 0.thorpej
2021-10-12fix various typos, mainly in comments.andvar
2021-10-09Modularize compat_linux(8) for aarch64.ryo
2021-09-23remove stray char.christos
2021-09-23add support COMPAT_LINUX for aarch64ryo
2021-09-21linux_sys_fstatat64: Add support for AT_EMPTY_PATH flag.rin
This is required for rtld shipped with glibc 2.33. Now, userland of Fedora 34 is working fine on NetBSD/amd64.
2021-09-20Regen for preadv(2) / pwritev(2).thorpej
2021-09-20Add preadv(2) and pwritev(2) system calls to COMPAT_LINUX and COMPAT_LINUX32.thorpej
2021-09-20Regen for eventfd.thorpej
2021-09-20Add the eventfd system calls to COMPAT_LINUX and COMPAT_LINUX32.thorpej
2021-09-19Regen for timerfd.thorpej
2021-09-19Add the timerfd syscalls to COMPAT_LINUX and COMPAT_LINUX32.thorpej
2021-09-19Regen for POSIX timer syscalls.thorpej
2021-09-19Add the POSIX timer syscalls (timer_create(), timer_settime(), timer_gettime(),thorpej
timer_getoverrun(), and timer_delete()) to COMPAT_LINUX and COMPAT_LINUX32.
2021-09-19- LINUX_SIGEV_PAD is incorrect for 64-bit systems, because sigval_tthorpej
contains a pointer. Correct this. - Add routines to convert from Linux to native sigevent_t.
2021-09-07sys/compat: Memset zero before copyout.riastradh
Just in case of uninitialized padding which would lead to kernel stack disclosure. If the compiler can prove the memset redundant then it can optimize it away; otherwise better safe than sorry.
2021-08-09fix typos in asymmetry, asymmetric(al), symmetrical.andvar

2020-10-24Fix compat with Linux programs that use longer namelen for socketsmgorny
Linux is less strict than NetBSD and permits namelen to be larger than valid struct sockaddr_in*. If this is the case, truncate the value to the correct size, so that NetBSD networking does not return an error. Reviewed by kamil

2020-09-05Round of uvm.h cleanup.riastradh
The poorly named uvm.h is generally supposed to be for uvm-internal users only. - Narrow it to files that actually need it -- mostly files that need to query whether curlwp is the pagedaemon, which should maybe be exposed by an external header. - Use uvm_extern.h where feasible and uvm_*.h for things not exposed by it. We should split up uvm_extern.h but this will serve for now to reduce the uvm.h dependencies. - Use uvm_stat.h and #ifdef UVMHIST uvm.h for files that use UVMHIST(ubchist), since ubchist is declared in uvm.h but the reference evaporates if UVMHIST is not defined, so we reduce header file dependencies. - Make uvm_device.h and uvm_swap.h independently includable while here. ok chs@
2020-09-03The conversion of FPU tracking to PCU rendered the fpcurlwp variablethorpej
unmaintained, which broke FP status info in the COMPAT_LINUX sigcontext. Use the new API, which will at least be closer to correct.

2020-06-11Counter tweaks:ad
- Don't need to count anonpages+filepages any more; clean+unknown+dirty for each kind of page can be summed to get the totals. - Track the number of free pages with a counter so that it's one less thing for the allocator to do, which opens up further options there. - Remove cpu_count_sync_one(). It has no users and doesn't save a whole lot. For the cheap option, give cpu_count_sync() a boolean parameter indicating that a cached value is okay, and rate limit the updates for cached values to hz.
2020-06-11uvm_availmem(): give it a boolean argument to specify whether a recentad
cached value will do, or if the very latest total must be fetched. It can be called thousands of times a second and fetching the totals impacts not only the calling LWP but other CPUs doing unrelated activity in the VM system.
2020-05-23Move proc_lock into the data segment. It was dynamically allocated becausead
at the time we had mutex_obj_alloc() but not __cacheline_aligned.
2020-05-14Fix previous; specify lwpid for curlpw in the case of pid == 0.rin
For linux_sys_sched_setaffinity, pid == 0 means the current thread. On the other hand, for our native sys_sched_setaffinity, lid == 0 means all lwp's that belong to the process.
2020-05-03Always clear FUTEX_PRIVATE_FLAG for Linux processes. NetBSD-native futexesthorpej
exist in different namespace depending on FUTEX_PRIVATE_FLAG. This appears not to be the case in Linux, and some futex users will mix private and non- private ops on the same futex object. Provide a convenience wrapper that puts this logic in one place witn a comment explaining why. While here, move the Linux futex wrapper out of its own file and plop it in linux_misc.c, which is where it lives in the linux32 module.
2020-04-29Fix proc lookup by distinguishing between the "tgid" and "tid" cases.thorpej
2020-04-29Fix proc / lwp lookup processing in linux_sys_sched_getaffinity()thorpej
and linux_sys_sched_setaffinity(). They were incorrect even before the LWP ID changes, but those changes exposed the latent bugs.
