| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* MFC r337696: Use INCS for non-sys/ libnvpair and libzfs_core includesKyle Evans2018-08-201-6/+0
| | | | | | | | | | | | | | | | 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. Notes: svn path=/stable/11/; revision=338080

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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | Add kernel and userspace code to dump the firmware state of supported ConnectX-4/5 devices in mlx5core. The dump is obtained by reading a predefined register map from the non-destructive crspace, accessible by the vendor-specific PCIe capability (VSC). The dump is stored in preallocated kernel memory and managed by the mlx5tool(8), which communicates with the driver using a character device node. The utility allows to store the dump in format <address> <value> into a file, to reset the dump content, and to manually initiate the dump. A call to mlx5_fwdump() should be added at the places where a dump must be fetched automatically. The most likely place is right before a firmware reset request.

| | | | | | | | | | | | | | | | | | | Use the __alloc_size2 attribute where relevant. This follows the documented use in GCC. It is basically only relevant for calloc(3), reallocarray(3) and mallocarray(9). NOTE: Without this change clang 5.0.1 can produce incorrect optimisation code for static processing of data using the allocated object. For example this has been seen compiling the mlx4 core module, which allocates a fixed size array which is then sorted by a fixed order loop. The optimised result, -O2, is incorrect unless this patch is in place.

CAVEAT EMPTOR: Partitioning eMMC devices is a one-time operation. o Now that properly issuing CMD6 is crucial (so data isn't written to the wrong partition for example), make a step into the direction of correctly handling the timeout for these commands in the MMC layer. Also, do a SEND_STATUS when CMD6 is invoked with an R1B response as recommended by relevant specifications. o Add an IOCTL interface to mmcsd(4); this is sufficiently compatible with Linux so that the GNU mmc-utils can be ported to and used with FreeBSD (note that due to the remaining deficiencies outlined above SANITIZE operations issued by/with `mmc` currently most likely will fail). These latter have been added to ports as sysutils/mmc-utils. Among others, the `mmc` tool of mmc-utils allows for partitioning eMMC devices (tested working). o For devices following the eMMC specification v4.41 or later, year 0 is 2013 rather than 1997; so correct this for assembling the device ID string properly. o Let mmcsd.ko depend on mmc.ko. Additionally, bump MMC_VERSION as at least for some of the above a matching pair is required. o In the ACPI front-end of sdhci(4) describe the Intel eMMC and SDXC controllers as such in order to match the PCI one. Additionally, in the entry for the 80860F14 SDXC controller remove the eMMC-only SDHCI_QUIRK_INTEL_POWER_UP_RESET. Notes: svn path=/stable/11/; revision=318197

This driver exposes two device files to the userland: /dev/hv_fsvss_dev Normally userland programs should _not_ mess with this device file. It is currently used by the hv_vss_daemon(8), which freezes and thaws the filesystem. NOTE: currently only UFS is supported, if the system mounts _any_ other filesystems, the hv_vss_daemon(8) will veto the VSS process. If hv_vss_daemon(8) was disabled, then this device file must be opened, and proper ioctls must be issued to keep the VSS working. /dev/hv_appvss_dev Userland application can opened this device file to receive the VSS freeze notification, hold the VSS for a while (mainly to flush application data to filesystem), release the VSS process, and receive the VSS thaw notification i.e. applications can run again. The VSS will still work, even if this device file is not opened. However, only filesystem consistency is promised, if this device file is not opened or is not operated properly. hv_vss_daemon(8) is started by devd(8) by default.

| | | | | | | | | | | | | | libc++'s stddef.h includes an existing definition of max_align_t for C++11, but it is only defined for C++, not for C. In addition, GCC and clang both define an alternate version of max_align_t that uses a union of multiple types rather than a plain long double as in libc++. This adds a __max_align_t to <sys/_types.h> that matches the GCC and clang definition that is mapped to max_align_t in <stddef.h>. PR: 210890 Notes: svn path=/stable/11/; revision=309258

| | | | | | | | | | | | | | | | | | | | | | | | | Improve typing of POSIX search tree functions. Back in 2015 when I reimplemented these functions to use an AVL tree, I was annoyed by the weakness of the typing of these functions. Both tree nodes and keys are represented by 'void *', meaning that things like the documentation for these functions are an absolute train wreck. To make things worse, users of these functions need to cast the return value of tfind()/tsearch() from 'void *' to 'type_of_key **' in order to access the key. Technically speaking such casts violate aliasing rules. I've observed actual breakages as a result of this by enabling features like LTO. I've filed a bug report at the Austin Group. Looking at the way the bug got resolved, they made a pretty good step in the right direction. A new type 'posix_tnode' has been added to correspond to tree nodes. It is still defined as 'void' for source-level compatibility, but in the very far future it could be replaced by a proper structure type containing a key pointer.

It allows using unmodified (apart from header name) input evdev drivers in Xorg, Wayland, Qt. This commit has only generic kernel API. evdev support for individual hardware drivers like ukbd, ums, atkbd, etc. will be committed later. Project was started by Jakub Klama as part of GSoC 2014. Jakub's evdev implementation was later used as a base, updated and finished by Vladimir Kondratiev.

| | | | | | | | | | | | | | | | | | | | | | | | | | | 1) _locale.h LC_*_MASK bit shifting order was partially broken from the initial commit time at year 2012. Only LC_COLLATE_MASK and LC_CTYPE_MASK are in the right order. The order here should match XLC_* from "xlocale_private.h" which, in turn, match LC_* publicly visible order from <locale.h> which determines how locale components are stored in the structure. LC_*_MASK -> XLC_* translation done as "ffs(mask) - 1" in the querylocale() and equivalent shift loop in the newlocale(), so mapped to some wrong components (excluding two mentioned above). Formally the fix is ABI breakage, but old code using those masks never works properly in any case. Only newlocale() and querylocale() are affected. 2) msgcat.c Use current locale (f.e. set by thread). It was global locale always previously. PR: 211743 Notes: svn path=/stable/11/; revision=304863

* Implement an NSS backend for netgroups and add getnetgrent_r(3).Mark Johnston2016-06-091-0/+1
| | | | | | | | | | | | | | | | | | | | | This support appears to have been documented in nsswitch.conf(5) for some time. The implementation adds two NSS netgroup providers to libc. The default, compat, provides the behaviour documented in netgroup(5), so this change does not make any user-visible behaviour changes. A files provider is also implemented. innetgr(3) is implemented as an optional NSS method so that providers such as NIS which are able to implement efficient reverse lookup can do so. A fallback implementation is used otherwise. getnetgrent_r(3) is added for convenience and to provide compatibility with glibc and Solaris. With a small patch to net/nss_ldap, it's possible to specify an ldap netgroup provider, allowing one to query nisNetgroupTriple entries.
