* libsys: relocate implementations and manpagesBrooks Davis2024-02-051-443/+0
| | | | | | | | | Remove core system call implementations and documentation to lib/libsys and lib/libsys/<arch> from lib/libc/sys and lib/libc/<arch>/<sys>. Update paths to allow libc to find them in their new home. Reviewed by: kib, emaste, imp Pull Request: https://github.com/freebsd/freebsd-src/pull/908

* Document EINTEGRITY errors for many system calls.John Baldwin2020-03-301-1/+4
| | | | | | | | | | | | | | | | | | | EINTEGRITY was previously documented as a UFS-specific error for mount(2). This documents EINTEGRITY as a filesystem-independent error that may be reported by the backing store of a filesystem. While here, document EIO as a filesystem-independent error for both mount(2) and posix_fadvise(2). EIO was previously only documented for UFS for mount(2).

| | | | | | | | | | | | back to the lever before r343030. For 64-bit machines reduce it slightly, too. Together with r343030 I bumped the limit up to the value we use at Netflix to serve 100 Gbit/s of sendfile traffic, and it probably isn't a good default.

* New sendfile(2) syscall. A joint effort of NGINX and Netflix from 2013 andGleb Smirnoff2016-01-081-32/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | up to now. The new sendfile is the code that Netflix uses to send their multiple tens of gigabits of data per second. The new implementation features asynchronous I/O, when I/O operations are launched, but not awaited to be complete. An explanation of why such behavior is beneficial compared to old one is going to be too long for a commit message, so we will skip it here. Additional features of new syscall are extra flags, which provide an application more control over data sent. The SF_NOCACHE flag tells kernel that data shouldn't be cached after it was sent. The SF_READAHEAD() macro allows to specify readahead size in pages. The new syscalls is a drop in replacement. No modifications are required to applications. One can take nginx binary for stable/10 and run it successfully on head. Although SF_NODISKIO lost its original sense, as now sendfile doesn't block, and now means something completely different (tm), using the new sendfile the old way is absolutely safe.
