r336017 This exposes ZFS user and group quotas via the normal quatactl(2) mechanism. (Read-only at this point, however.) In particular, this is to allow rpc.rquotad query quotas for NFS mounts, allowing users to see their quotas on the hosts using the datasets. The changes specifically: * Add new RPC entry points for querying quotas. * Changes the library routines to allow non-UFS quotas. * Changes rquotad to check for quotas on mounted filesystems, rather than being limited to entries in /etc/fstab * Lastly, adds a VFS entry-point for ZFS to query quotas. Note that this makes one unavoidable behavioural change: if quotas are enabled, then they can be queried, as opposed to the current method of checking for quotas being specified in fstab. (With ZFS, if there are user or group quotas, they're used, always.) r338799 Author: kib Fix ZFS VFS op quotactl to follow busy protocol. Approved by: mav Sponsored by: iXsystems, inc

POSIX compliance improvements in the pthread(3) functions. This basically adds makes use of the C99 restrict keyword, and also adds some 'const's to four threading functions: pthread_mutexattr_gettype(), pthread_mutexattr_getprioceiling(), pthread_mutexattr_getprotocol(), and pthread_mutex_getprioceiling. The changes are in accordance to POSIX/SUSv4-2018. Hinted by: DragonFlyBSD Relnotes: yes

MFC r337696: Use INCS for non-sys/ libnvpair and libzfs_core includes

2018-08-20T00:53:38Z

While nothing was wrong with libnvpair.h, libzfs_core.h was only guarded by MK_CDDL rather than MK_CDDL && MK_ZFS. Rather than ugl'if'ying include/Makefile to impose the extra restriction, just move the non-sys/ includes into INCS with the respect lib builds. This has the added bonus of allowing third party packagers to try and split these libs out of the FreeBSD-runtime package, if they are so inclined. The sys/ include was left alone- generally userland libraries shouldn't install kernel headers.

cacos(3): correct spelling of 'I' In some cases we had 'i' instead of 'I'. PR: 195517 Submitted by: stephen MFC r329259 (by eadler): msun: signed overflow in atan2 As a component of atan2(y, x), the case of x == 1.0 is farmed out to atan(y). The current implementation of this comparison is vulnerable to signed integer underflow (that is, undefined behavior), and it's performed in a somewhat more complicated way than it need be. Change it to not be quite so cute, rather directly comparing the high/low bits of x to the specific IEEE-754 bit pattern that encodes 1.0. Note that while there are three different e_atan* files in the relevant directory, only this one needs fixing. e_atan2f.c already compares against the full bit pattern encoding 1.0f, while e_atan2l.cuses bitwise-ands/ors/nots and so doesn't require a change.

r315733 (imp): Impelemnt ttys onifexists in init. Implement a new init(8) option in /etc/ttys. If this option is present on the entry in /etc/ttys, the entry will be active if and only if it exists. If the name starts with a '/', it will be considered an absolute path. If not, it will be a path relative to /dev. This allows one to turn off video console getty that aren't present (while running a getty on them even when they aren't the system console). Likewise with serial ports. It differs from onifconsole in only requiring the device exist rather than it be listed as one of the system consoles. r315737 (ngie): Unbreak world by adding sys/stat.h for stat(2) r315740 (imp): Simplify the code a little. r330054 (trasz): Improve missing tty handling in init(8). This removes a check that did nothing - it was checking for ENXIO, which, with devfs, is no longer returned - and was badly placed anyway, and replaces it with similar one that works, and is done just before starting getty, instead of being done when rereading ttys(5). From the practical point of view, this makes init(8) handle disappearing terminals (eg /dev/ttyU*) gracefully, without unneccessary getty restarts and resulting error messages.
