_null.h

Remove duplicated contents, either a patch bug or PEBKAC.

_time.h

Move CLOCKS_PER_SEC to sys/_time.h so the kernel has access to it. This will be used in waitid(2) to set si_utime and si_stime. The definition of struct timespec also moves from time.h to sys/_time.h for struct itimerspec. OK kettenis@

clockintr.h

clockintr: rename "struct clockintr_queue" to "struct clockqueue"

2 years ago

conf.h

Cleanup the kernel fuse device code to remove support for ioctl. This is no longer needed since an fbuf is now read or written in one go, rather than a combination of read(2) or write(2) and ioctl(2) to read or write the buffer used by the vfs syscalls read, write, readlink and readdir.

7 months ago

core.h

Fix core file writing when a file map into memory has later been truncated to be smaller than the mapping. Record which memory segments are backed by vnodes while walking the uvm map and later suppress EFAULT errors caused by the underlying file being truncated. okay miod@

disk.h

Expand the masks tracking disk partition status to 64 bits.

6 months ago

disklabel.h

Begin transition to 52-partition support. The partition encoding used to be lowest 4 bits of dev_t, and now becomes 6. This supplies 64 partitions in struct disklabel.d_partitions[MAXPARTITIONSUNIT], but we only use 52 of these slots (an architecture can be either 16 partition or 52 partition, depending on MD define MAXPARTITIONS). The 52-partition limit is due to single-character representation limit of a-zA-Z. We supply a backwards-compat ioctl for a while which can read an disklabel structure.

errno.h

Add additional errno values required by POSIX.

8 years ago

evcount.h

Add support for per-cpu event counters, to be used for clock and IPI counters where the event being counted occurs across all CPUs in the system. Counter instances can be made per-cpu by calling evcount_percpu() after the counter is attached, and this can occur before or after all system CPUs are attached. Per-cpu counter instances should be incremented using evcount_inc().

kqueue: Implement EVFILT_USER

11 months ago

eventvar.h

Unwrap klist from struct selinfo as this code no longer uses selwakeup().

3 years ago

exec.h

In the old gprof profiling subsystem, the simplistic profil() syscall told the kernel about the sample buffer, and then the normal exit-time _mcleanup() would finalize the buffer, open()'ed a file and write out the details. This file opening has become increasingly impossible because of our privsep / privdrop, chroot, setresuid uid-dropping, pledge, unveil, and other efforts. So people stopped using gprof. Programs which needed profiling needed substantial mitigation removal changes to put them under test.

10 months ago

exec_elf.h

Implement MD corefile notes and use them to write out the PAC note on arm64.

exec_script.h

the SETUIDSCRIPTS define is no longer needed since the code was unifdef a few years ago. spotted by tb.

extent.h

Implement extent_alloc_region_with_descr(9) which is the equivalent of extent_alloc_region(9) that uses a pre-allocated region descriptor.

2 years ago

fcntl.h

Implement the POSIX-2024 close-on-fork flag, but modified to be reset on exec as preserving it across exec is not necessary for its original purpose and has security and usability concerns.

futex.h

avoid lock contention in futex syscalls

11 months ago

gmon.h

This thread-aware profiling support diff comes from Yuichiro NAITO. At runtime, profiling data is stored per-thread. Upon termination, the per-thread profiling data pools are merged into a into a single record, which is then written out (using the new kernel-assisted system). I think the original gmon merging parts may have come from or been inspired by someone at NetBSD. This has been delayed because there were concerns about adding a TLS object which would require other library cranks, so this rides all the major cranks today. ok kettenis tb claudio sthen etc etc etc

Further standards compliance fixes: export LONG_BIT, WORD_BIT, and NL_{ARG,LANG,MSG,SET,TEXT}MAX with newer POSIX. Hide {FLT,DBL}_{DIG,MAX,MIN} and {PASS,TMP,NL_N}_MAX with newer XPG. Make _POSIX_NGROUPS_MAX and _POSIX_OPEN_MAX conditional on the POSIX version, like _POSIX_TZNAME_MAX already is. Add some more _POSIX_* and _XOPEN_* 'specified' limits.

13 years ago

lock.h

Remove the lockmgr() API. It is only used by filesystems, where it is a trivial change to use rrw locks instead. All it needs is LK_* defines for the RW_* flags.

9 years ago

lockf.h

Move lockf structures from header to implementation since external users only need a lockf_state pointer by now.

7 years ago

malloc.h

Limit net.bpf.maxbufsize sysctl(8) to a value that malloc(9) can handle. Introduce MALLOC_MAX definition to keep this value in sync and use it system wide.

resource.h

Move the declarations for dogetrusage(), itimerround(), and dowait4() to sys/*.h headers so that the compat/linux code can use them. Change dowait4() to not copyout() the status value, but rather leave that for its caller, as compat/linux has to translate it, with the side benefit of simplifying the native code.

select.h

More #include cleanup per POSIX: - <sys/types.h>: don't pull in <sys/select.h> - <sys/select.h>: don't pull in <sys/time.h>, but rather declare timeval and timespec locally - <sys/time.h>: *do* always pull in <sys/select.h> - <sys/socket.h>: declare timeval if __BSD_VISIBLE for struct splice

sigio.h

Unify handling of ioctls FIOSETOWN/SIOCSPGRP/TIOCSPGRP and FIOGETOWN/SIOCGPGRP/TIOCGPGRP. Do this by determining the meaning of the ID parameter inside the sigio code. Also add cases for FIOSETOWN and FIOGETOWN where there have been TIOCSPGRP and TIOCGPGRP before. These changes allow removing the ID translation from sys_fcntl() and sys_ioctl().

6 years ago

signal.h

Some programs create a PROT_NONE guard page at the far-end of the provided stack buffer. With a page-aligned buffer, creating a MAP_STACK sub-region would undo the PROT_NONE guard. Ignore that last page. (We could check if the last page is non-RW before choosing to skip it. But we've already elected to grow STK sizes to compensate. Always ignoring the last page makes it a non-MAP_STACK guard page which can be opportunistically discovered) ok semarie stefan kettenis

task.h

Add support for remote coverage to kcov. Remote coverage is collected from threads other than the one currently having kcov enabled. A thread with kcov enabled occasionally delegates work to another thread, collecting coverage from such threads improves the ability of syzkaller to correlate side effects in the kernel caused by issuing a syscall.

time.h

Add a helper function TICKS_TO_NSEC() to transform ticks into nanoseconds. This is done since the multiplication needs to happen with uint64_t types to prevent overflows. Ticks use most probably a type of int and tick_nsec is also defined as an int. OK dlg@
