* Add collation version support to querylocale(3).Thomas Munro2020-11-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Provide a way to ask for an opaque version string for a locale_t, so that potential changes in sort order can be detected. Similar to ICU's ucol_getVersion() and Windows' GetNLSVersionEx(), this API is intended to allow databases to detect when text order-based indexes might need to be rebuilt. The CLDR version is extracted from CLDR source data by the Makefile under tools/tools/locale, written into the machine-generated Makefile under shared/colldef, passed to localedef -V, and then written into LC_COLLATE file headers. The initial version is 34.0. tools/tools/locale was recently updated to pull down 35.0, but the output hasn't been committed under share/colldef yet, so that will provide the first observable change when it happens. Other versioning schemes are possible in future, because the format is unspecified.

* Remove obsolete check for GCC < 3 and support for Intel CompilerWarner Losh2020-10-242-4/+1
| | | | | | | | | | | | | | We no longer support old versions of GCC. Remove this check by assuming it's false. That will make the entire expression false. Also remove support for Intel compiler, it's badly bitrotted. Technically, this removes support for C89 and K&R from compilers that don't define _Bool in those compilation environments as well. I'm unaware of any working compiler today for which that would be relevant (pcc has it and tcc sadly isn't working for other reasons), though if one pops up in ports, I'll work to resolve the issue.

* Add search of LOCALBASE/share/calendar for calendars supplied by a port.Stefan Eßer2020-10-231-1/+4
| | | | | | | | | | | | | | | | | Calendar files in LOCALBASE override similarily named ones in the base system. This could easily be changed if the base system calendars should have precedence, but it could lead to a violation of POLA since then the port's files were ignored unless those in base have been deleted. There was no definition of _PATH_LOCALBASE in paths.h, but verbatim uses of /usr/local existed for _PATH_DEFPATH. Use _PATH_LOCALBASE here to ease a consistent modification of this prefix.

* Merge OpenZFS support in to HEAD.Matt Macy2020-08-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The primary benefit is maintaining a completely shared code base with the community allowing FreeBSD to receive new features sooner and with less effort. I would advise against doing 'zpool upgrade' or creating indispensable pools using new features until this change has had a month+ to soak. Work on merging FreeBSD support in to what was at the time "ZFS on Linux" began in August 2018. I first publicly proposed transitioning FreeBSD to (new) OpenZFS on December 18th, 2018. FreeBSD support in OpenZFS was finally completed in December 2019. A CFT for downstreaming OpenZFS support in to FreeBSD was first issued on July 8th. All issues that were reported have been addressed or, for a couple of less critical matters there are pull requests in progress with OpenZFS. iXsystems has tested and dogfooded extensively internally. The TrueNAS 12 release is based on OpenZFS with some additional features that have not yet made it upstream. Improvements include: project quotas, encrypted datasets, allocation classes, vectorized raidz, vectorized checksums, various command line improvements, zstd compression.

* Implement a close_range(2) syscallKyle Evans2020-04-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | close_range(min, max, flags) allows for a range of descriptors to be closed. The Python folk have indicated that they would much prefer this interface to closefrom(2), as the case may be that they/someone have special fds dup'd to higher in the range and they can't necessarily closefrom(min) because they don't want to hit the upper range, but relocating them to lower isn't necessarily feasible. sys_closefrom has been rewritten to use kern_close_range() using ~0U to indicate closing to the end of the range. This was chosen rather than requiring callers of kern_close_range() to hold FILEDESC_SLOCK across the call to kern_close_range for simplicity. The flags argument of close_range(2) is currently unused, so any flags set is currently EINVAL. It was added to the interface in Linux so that future flags could be added for, e.g., "halt on first error" and things of this nature. This patch is based on a syscall of the same design that is expected to be merged into Linux.

* Introduce nexthop objects and new routing KPI.Alexander V. Chernikov2020-04-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the foundational change for the routing subsytem rearchitecture. More details and goals are available in https://reviews.freebsd.org/D24141 . This patch introduces concept of nexthop objects and new nexthop-based routing KPI. Nexthops are objects, containing all necessary information for performing the packet output decision. Output interface, mtu, flags, gw address goes there. For most of the cases, these objects will serve the same role as the struct rtentry is currently serving. Typically there will be low tens of such objects for the router even with multiple BGP full-views, as these objects will be shared between routing entries. This allows to store more information in the nexthop. New KPI: struct nhop_object *fib4_lookup(uint32_t fibnum, struct in_addr dst, uint32_t scopeid, uint32_t flags, uint32_t flowid); struct nhop_object *fib6_lookup(uint32_t fibnum, const struct in6_addr *dst6, uint32_t scopeid, uint32_t flags, uint32_t flowid); These 2 function are intended to replace all all flavours of <in_|in6_>rtalloc[1]<_ign><_fib>, mpath functions and the previous fib[46]-generation functions. Upon successful lookup, they return nexthop object which is guaranteed to exist within current NET_EPOCH. If longer lifetime is desired, one can specify NHR_REF as a flag and get a referenced version of the nexthop. Reference semantic closely resembles rtentry one, allowing sed-style conversion. Additionally, another 2 functions are introduced to support uRPF functionality inside variety of our firewalls. Their primary goal is to hide the multipath implementation details inside the routing subsystem, greatly simplifying firewalls implementation: int fib4_lookup_urpf(uint32_t fibnum, struct in_addr dst, uint32_t scopeid, uint32_t flags, const struct ifnet *src_if); int fib6_lookup_urpf(uint32_t fibnum, const struct in6_addr *dst6, uint32_t scopeid, uint32_t flags, const struct ifnet *src_if); All functions have a separate scopeid argument, paving way to eliminating IPv6 scope embedding and allowing to support IPv4 link-locals in the future. Structure changes: * rtentry gets new 'rt_nhop' pointer, slightly growing the overall size. * rib_head gets new 'rnh_preadd' callback pointer, slightly growing overall sz. Old KPI: During the transition state old and new KPI will coexists. As there are another 4-5 decent-sized conversion patches, it will probably take a couple of weeks. To support both KPIs, fields not required by the new KPI (most of rtentry) has to be kept, resulting in the temporary size increase. Once conversion is finished, rtentry will notably shrink.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | rand(3)'s standard C API is extremely limiting, but we can do better than the historical 32-bit state Park-Miller LCG we've shipped since 2001: r73156. The justification provided at the time for not using random(3) was that rand_r(3) could not be made to use the same algorithm. That is still true. However, the irrelevance of rand_r(3) is increasingly obvious. Since that time, POSIX has marked the interface obsolescent. rand_r(3) never became part of the standard C library. If not for API compatibility reasons, I would just remove rand_r(3) entirely. So, I do not believe it is a problem for rand_r(3) and rand(3) to diverge. The 12 ABI is maintained with compatibility definitions, but this revision does subtly change the API of rand(3). The sequences of pseudorandom numbers produced in programs built against new versions of libc will differ from programs built against prior versions of libc.

On legacy GCC 4, the macro expands to just the __deprecated__ attribute; on modern GCC or Clang, the macro expands to the parameterized variant with the message.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It serves no useful purpose and wasn't as popular as its equally meritless cousin, srandomdev(3). Setting aside the problems with rand(3) in general, the problem with this interface is that the seed isn't shared with the caller (other than by attacking the output of the generator, which is trivial, but not a hallmark of pleasant API design). The (arguable) utility of rand(3) or random(3) is as a semi-fast simulation generator which produces consistent results from a given seed. These are mutually at odd. Furthermore, sometimes people got the mistaken impression that a high quality random seed meant a weak generator like rand(3) or random(3) could be used for things like cryptographic key generation. This is absolutely not so. The API was never part of a standard and was not widely used in tree. Existing in-tree uses have all been removed. Possible replacement in out of tree codebases: char buf[3]; time_t t; time(t); strftime(buf, sizeof(buf), "%S", gmtime(&t)); srand(atoi(buf)); Relnotes: yes Notes: svn path=/head/; revision=355747

| | | | | | | | | | | | | | | | | | | | | NANDFS has been broken for years. Remove it. The NAND drivers that remain are for ancient parts that are no longer relevant. They are polled, have terrible performance and just for ancient arm hardware. NAND parts have evolved significantly from this early work and little to none of it would be relevant should someone need to update to support raw nand. This code has been off by default for years and has violated the vnode protocol leading to panics since it was committed. Numerous posts to arch@ and other locations have found no actual users for this software.
