Freebsd logo (75 pix) De leden van het FreeBSD Release Engineering Team hebben de eerste update voor versie 9.0 van FreeBSD uitgebracht. FreeBSD is in 1993 ontstaan en wordt als één geheel ontwikkeld, in tegenstelling tot bijvoorbeeld Linux, waarvan de kernel door de ene groep ontwikkelaars wordt onderhouden en bepaalde applicaties weer door anderen. Hierdoor wordt FreeBSD over het algemeen als stabieler en robuuster beschouwd dan diverse andere besturingssystemen. Downloads voor de verschillende processorarchitecturen zijn beschikbaar via ftp en bittorrent. Hieronder zijn de releasenotes van versie 9.1 te vinden, met daarin de belangrijkste veranderingen.

    • It now supports a timeout on positive name cache entries on the client side. A new mount option nametimeo has been added and set to 60 (in seconds) by default.[r233326]
    • A memory leak when a ZFS volume is exported via the FreeBSD NFS server has been fixed.[r234740]
    • A bug has been fixed. When a process writes to an mmap-backed file on an NFS filesystem, flushing changes to the data could fail under some circumstances such as errors due to permission mismatch, and this failure could not detected as an error. A new sysctl(8) variable vfs.nfs.nfs_keep_dirty_on_error has been added to control the behavior on the client side related to this issue. When this is set to 1, the pages where a write operation failed are kept dirty. The default value is set to 0.[r233730]
    • The nfsv4(4) filesystem now supports a sysctl(8) variable vfs.nfsd.disable_checkutf8. This disables the check for UTF-8 compliance in the filenames. This is disabled by default. Note that enabling this may help some interoperability issues but results in an NFSv4 server that is non-RFC 3530 compliant.[r229799]
  • The tmpfs(5) filesystem is not an experimental implementation anymore.[r234511]
  • The tmpfs(5) filesystem now supports a sysctl(8) variable vfs.tmpfs.memory_reserved to set the amount of required free pages when tmpfs(5) attempts to allocate a new node.[r234849]
  • FreeBSD ZFS filesystem has been updated by merging improvements from illumos project. The following changes are made:[r229578, r232328]
    • New properties, clones and written, have been added.
    • The The zfs(8) sendcommand now reports an estimated size of the stream.
    • The zfs(8) destroy command now reports an estimate of the space which would be reclaimed, when -nflag is specified.
    • The zfs(8) get command now supports the -t type flag to specify the data type.
  • The dhclient(8) utility now supports domain-search (option number 119, described in RFC 3397). This allows a DHCP server to publish a list of implicit domain suffixes used during name lookup. If this option is specified, a search keyword will be added to /etc/resolv.conf.[r230597]
  • A bug in the gcc(1) compiler has been fixed. It could lead to incorrect calculations when -ffast-math is specified.[r234023]
  • The ifconfig(8) utility now supports a vlanhwcsum parameter to set or reset checksum offloading capability on VLANs.[r231221]
  • The ifconfig(8) utility now supports a carp state parameter to set the state to backup or master forcibly.[r232486]
  • The jail(8) utility now supports a configuration file (jail.conf(5)) for complex configurations.[r235839]
  • Lock handling performance in the libthr pthread library has been improved. It now works 10 times faster especially under the condition that a mutex is heavily contested.[r234372]
  • libcxxrt and libc++ C++ runtime libraries from PathScale have been imported. This implementation is a full replacement for the GNU libsupc++ library for platforms that use the Itanium C++ ABI, including i386 and amd64, and will replace portions of the C++ stack previously only available under the GPL. It provides implementations of the dynamic features of C++, including dynamic casting, exception handling, and thread-safe static initializers.[r235798]
  • The rtld(1) run-time linker now supports GCC's RELRO (RElocation Read-Only). This prevents the GOT (Global Offset Table) from being overwritten.[r231579]
  • The rtld(1) run-time linker now supports a GNU hash section (DT_GNU_HASH), which is a replacement of optional ELF hash section.[r235396]
  • The setbuf(1) utility and libstdbuf library have been added. This controls the default buffering behavior of standard stdio streams.[r235139]
  • The xlocale(3) API has been implemented. This consists of _l-suffixed versions of various standard library functions that use the global locale, making them take an explicit locale parameter and allowing thread-safe extended locale support. This is from Apple Darwin, and mainly for use by libc++.[r235785]
  • ISC BIND has been updated to version 9.8.3-P4.[r241417]
  • The compiler-rt library, which provides low-level target-specific interfaces such as functions in libgcc, has been updated to revision 147467.[r236018]
  • file (file(1)) has been updated to version 5.11.[r237983]
  • GNU gperf(1) has been updated to version 3.0.3 (the latest GPLv2-licensed version).[r230237]
  • libarchive, bsdtar(1), and cpio(1) have been updated to version 2.8.5.[r229588]
  • libpcap library has been updated to 1.2.1.[r236167]
  • libstdc++ have been updated to rev 135556 of gcc-4_2-branch (the last LGPLv2-licensed version).[r229551]
  • The LLVM compiler infrastructure and clang, a C language family front-end, version 3.1 have been imported. Note that it is not used for building the FreeBSD base system by default.[r236144]
  • The netcat utility has been updated to version 5.1.[r235971]
  • OpenSSL has been updated to version 0.9.8x.[r237998]
  • tcpdump (tcpdump(1)) utility has been updated to version 4.2.1.[r236192]

Ben toevallig met een 9.0 installatie bezig. Waarschijnlijk toch maar even opnieuw doen, of de upgrade testen.


Wat is ZFS toch ook een heerlijk iets van FreeBSD, dit icm met de Packet Filter (PF) is dit voor mij de reden om altijd voor FreeBSD te kiezen.
"A memory leak when a ZFS volume is exported via the FreeBSD NFS server has been fixed"

Komende week maar eens upgraden :)
Enorme lijst voor een minor update. Belangrijke update is het zeker te noemen met verbeteringen aan bestandssystemen ZFS, NFS en TMPFS. Fijn dat USB nu standaard in powersafe modus draait. Scheelt weer op de stroomkosten. Ben benieuwd hoe de desktopversie PC-BSD zich op mijn ULVM i5 laptop gaat houden in combinatie met accuduur.
Voor fileservers wil ik op het ogenblik niets anders, want ZFS. Op dit moment verreweg het meest robuuste opslagsysteem dat je kan gebruiken, en ik ben blij dat de ontwikkeling hiervan doorgaat door de samenwerking tussen de FreeBSD en Illumos teams.

Alleen even kijken hoe we de v15 LSI SAS2008 driver (mps) erin gaan prakken, want die in 9.1-RELEASE is nog v14 en m'n controller firmware en 9.0-RELEASE driver is al v15 :P
Wellicht wacht ik wel tot LSI met een 9.1 driver komt...

Op dit item kan niet meer gereageerd worden.
