* open(2): Add O_DSYNC flag.Thomas Munro2021-01-082-1/+2
| | | | | | | | | | | | | | | POSIX O_DSYNC means that writes include an implicit fdatasync(2), just as O_SYNC implies fsync(2). VOP_WRITE() functions that understand the new IO_DATASYNC flag can act accordingly, but we'll still pass down IO_SYNC so that file systems that don't understand it will continue to provide the stronger O_SYNC behaviour. Flag also applies to fcntl(2). Reviewed by: kib, delphij Differential Revision: https://reviews.freebsd.org/D25090

* Merge commit d8a09b3a0 from openzfs git (by Ryan Libby):Ryan Libby2020-12-271-4/+6
| | | | | | | | | | | | | | | | | | lua: avoid gcc -Wreturn-local-addr bug Avoid a bug with gcc's -Wreturn-local-addr warning with some obfuscation. In buggy versions of gcc, if a return value is an expression that involves the address of a local variable, and even if that address is legally converted to a non-pointer type, a warning may be emitted and the value of the address may be replaced with zero. Howerver, buggy versions don't emit the warning or replace the value when simply returning a local variable of non-pointer type. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90737 Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Ryan Libby <rlibby@FreeBSD.org> Closes #11337

| | | | | | | | | | | | | | | | spa: avoid type narrowing warning Building the spa module for i386 caused gcc to emit -Wint-to-pointer-cast "cast to pointer from integer of different size" because spa.spa_did was uint64_t but pthread_join (via thread_join in spa_deactivate) takes a pointer (32-bit on i386). Define spa_did to be pointer-size instead. For now spa_did is in fact never non-zero and the thread_join could instead be ifdef'd out, but changing the size of spa_did may be more useful for the future.

| | | | | | | | | | | | | | | | | | | | Fix compiling on FreeBSD + gcc - don't assume illmnos bits This looks like it was once from the illumnos compat code. FreeBSD doesn't have cmn_err as a compiler format attribute, so it definitely errors out. It doesn't show up on LLVM because it doesn't trigger at all. Add in the format flags but keep them behind #if 0 for now; there are too many format issues that trigger when one does format checking in the shared code.

* Make MAXPHYS tunable. Bump MAXPHYS to 1M.Konstantin Belousov2020-11-282-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace MAXPHYS by runtime variable maxphys. It is initialized from MAXPHYS by default, but can be also adjusted with the tunable kern.maxphys. Make b_pages[] array in struct buf flexible. Size b_pages[] for buffer cache buffers exactly to atop(maxbcachebuf) (currently it is sized to atop(MAXPHYS)), and b_pages[] for pbufs is sized to atop(maxphys) + 1. The +1 for pbufs allow several pbuf consumers, among them vmapbuf(), to use unaligned buffers still sized to maxphys, esp. when such buffers come from userspace (*). Overall, we save significant amount of otherwise wasted memory in b_pages[] for buffer cache buffers, while bumping MAXPHYS to desired high value. Eliminate all direct uses of the MAXPHYS constant in kernel and driver sources, except a place which initialize maxphys. Some random (and arguably weird) uses of MAXPHYS, e.g. in linuxolator, are converted straight. Some drivers, which use MAXPHYS to size embeded structures, get private MAXPHYS-like constant; their convertion is out of scope for this work.

* Fix 32-bit build after r367229.Brandon Bergren2020-10-311-0/+2
| | | | | | | | | | | | | | | | The use of atomic_sub_64() in zfs_zstd.c was breaking the 32-bit build on platforms without native 64-bit atomics due to atomic_sub_64() not being available, and no fallback being provided in _STANDALONE. Provide a standalone stub to match atomic_add_64() using simple math. While this is not actually atomic, it does not matter in libsa context, since it always runs single-threaded and does not run under a scheduler.
