Samba 4 er et multifunksjonelt serverprodukt som ogs\u00e5 gir implementering av filserver, utskriftstjeneste og identifikasjonsserver (winbind).<\/p>\n<p>N\u00f8kkelfunksjoner <noindex><a rel=\"nofollow\" href=\"http:\/\/www.samba.org\/samba\/history\/samba-4.12.0.html\">endringer<\/a><\/noindex> i Samba 4.12:<\/p>\n<ul>\n<li class=\"l\"> Innebygde implementeringer av kryptografiske funksjoner er fjernet fra kodebasen til fordel for bruk av eksterne biblioteker. GnuTLS er valgt som hoved kryptobibliotek (krever minst versjon 3.4.7). I tillegg til \u00e5 redusere mulige trusler knyttet til identifisering av s\u00e5rbarheter i innebygde implementeringer av kryptoalgoritmer, har overgangen til GnuTLS ogs\u00e5 f\u00f8rt til en betydelig \u00f8kning i ytelsen ved bruk av kryptering i SMB3. Ved testing med CIFS-klienten fra Linux 5.3 ble det registrert en energibehov p\u00e5 opptil tre ganger raskere skriving og 2,5 ganger raskere lesing.\n<li class=\"l\"> En ny backend for s\u00f8k p\u00e5 SMB-deler med bruk av protokoll <noindex><a rel=\"nofollow\" href=\"https:\/\/wiki.samba.org\/index.php\/Spotlight\">Spotlight<\/a><\/noindex>, basert p\u00e5 s\u00f8kemotoren  <noindex><a rel=\"nofollow\" href=\"https:\/\/www.elastic.co\/elasticsearch\">Elasticsearch<\/a><\/noindex> (tidligere ble backend levert med <noindex><a rel=\"nofollow\" href=\"https:\/\/wiki.gnome.org\/Projects\/Tracker\">GNOME Tracker<\/a><\/noindex>). I tillegg er det lagt til verkt\u00f8yet \u00abmdfind\u00bb som implementerer en klient som tillater \u00e5 sende s\u00f8kesp\u00f8rsm\u00e5l til enhver SMB-server der RPC-tjenesten Spotlight kj\u00f8rer. Standardverdien for innstillingen \u00abspotlight backend\u00bb er endret til \u00abnoindex\u00bb (for Tracker eller Elasticsearch, m\u00e5 verdiene \u00abtracker\u00bb eller \u00abelasticsearch\u00bb angis direkte).\n<li class=\"l\"> Atferden til operasjonene \u2018net ads kerberos pac save\u2019 og \u2018net eventlog export\u2019 er endret, slik at de n\u00e5 ikke overskriver filen, men i tilfelle av eksport til en eksisterende fil gir en feil.\n<li class=\"l\"> I samba-tool er det forbedret \u00e5 legge til kontakter som medlemmer av grupper. Tidligere kunne man med kommandoen \u2018samba-tool group addmembers\u2019 bare legge til brukere, grupper og datamaskiner som nye medlemmer av grupper, men n\u00e5 er det st\u00f8tte for \u00e5 legge til kontakter som medlemmer av grupper.\n<li class=\"l\"> I samba-tool er filtrering etter organisatoriske enheter (OU, Organizational Unit) eller deltreer tillatt. Nye flagg \u2018\u2014base-dn\u2019 og \u2018\u2014member-base-dn\u2019 er lagt til, som gir mulighet til \u00e5 utf\u00f8re operasjonen bare med en bestemt del av Active Directory-treet, for eksempel kun innenfor en organisatorisk enhet (OU).\n<li class=\"l\"> En ny VFS-modul \u2018io_uring\u2019 er lagt til, som bruker det nye Linux-kjern grensesnittet <noindex><a rel=\"nofollow\" href=\"http:\/\/kernel.dk\/io_uring.pdf\">io_uring<\/a><\/noindex> for asynkron I\/O. Io_uring st\u00f8tter polling av I\/O og kan fungere med buffring (den tidligere foresl\u00e5tte mekanismen \u2018aio\u2019 st\u00f8ttet ikke buffered I\/O). N\u00e5r man bruker aktiv polling, overg\u00e5r io_uring betydelig aio i ytelse. I dag er st\u00f8tten for SMB_VFS_{PREAD,PWRITE,FSYNC}_SEND\/RECV implementert i Samba basert p\u00e5 io_uring, og overhead for vedlikehold av tr\u00e5dpool i brukerspace er redusert ved p\u00e5f\u00f8ring av standard VFS-backend. For \u00e5 bygge VFS-modulen \u2018io_uring\u2019 kreves biblioteket. <noindex><a rel=\"nofollow\" href=\"https:\/\/git.kernel.dk\/cgit\/liburing\/\">liburing<\/a><\/noindex> and Linux kernel 5.1+.\n<li class=\"l\"> In VFS, a special UTIME_OMIT time value can be specified to denote the need to ignore time in the SMB_VFS_NTIMES() function.\n<li class=\"l\"> I smb.conf er st\u00f8tten for parameteren \u2018write cache size\u2019 avbrutt, da dette har mistet mening etter at st\u00f8tte for io_uring ble tilgjengelig.\n<li class=\"l\"> In Samba-DC and Kerberos, support for encryption using the DES algorithm has been removed. The weak-crypto code has been removed from Heimdal-DC.\n<li class=\"l\"> The vfs_netatalk module has been removed, as it was no longer maintained and had become obsolete.\n<li class=\"l\"> The BIND9_FLATFILE backend has been declared deprecated and will be removed in one of the upcoming releases.\n<li class=\"l\"> The zlib library has been added to the build dependencies. The built-in zlib implementation has been removed from the codebase (the code was based on an old version of zlib where encryption support did not work properly).\n<li class=\"l\"> Fuzzing testing of the codebase has been established, including the service<br \/>\noss-fuzz. During fuzzing testing, many bugs have been identified and fixed.<\/p>\n<li class=\"l\"> The minimum Python version requirement has been raised from Python<br \/>\n3.4 til Python 3.5. Muligheten for \u00e5 bygge filserver med Python 2 er fortsatt bevart (f\u00f8r du kj\u00f8rer .\/configure og \u2018make\u2019, m\u00e5 milj\u00f8variabelen \u2018PYTHON=python2\u2019 settes).<\/p>\n<\/ul>\n<p><noindex><a rel=\"nofollow\" name=\"link\"><\/a><\/noindex><\/p>\n<p>Kilde: <a \ncontent=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=52475\">opennet.ru<\/a><\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u043b\u0435\u043d \u0440\u0435\u043b\u0438\u0437 Samba 4.12.0, \u043f\u0440\u043e\u0434\u043e\u043b\u0436\u0438\u0432\u0448\u0438\u0439 \u0440\u0430\u0437\u0432\u0438\u0442\u0438\u0435 \u0432\u0435\u0442\u043a\u0438 Samba 4 \u0441 \u043f\u043e\u043b\u043d\u043e\u0446\u0435\u043d\u043d\u043e\u0439 \u0440\u0435\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u0435\u0439 \u043a\u043e\u043d\u0442\u0440\u043e\u043b\u043b\u0435\u0440\u0430 \u0434\u043e\u043c\u0435\u043d\u0430 \u0438 \u0441\u0435\u0440\u0432\u0438\u0441\u0430 Active Directory, \u0441\u043e\u0432\u043c\u0435\u0441\u0442\u0438\u043c\u043e\u0433\u043e \u0441 \u0440\u0435\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u0435\u0439 Windows 2000 \u0438 \u0441\u043f\u043e\u0441\u043e\u0431\u043d\u043e\u0433\u043e \u043e\u0431\u0441\u043b\u0443\u0436\u0438\u0432\u0430\u0442\u044c \u0432\u0441\u0435 \u043f\u043e\u0434\u0434\u0435\u0440\u0436\u0438\u0432\u0430\u0435\u043c\u044b\u0435 Microsoft \u0432\u0435\u0440\u0441\u0438\u0438 Windows-\u043a\u043b\u0438\u0435\u043d\u0442\u043e\u0432, \u0432 \u0442\u043e\u043c \u0447\u0438\u0441\u043b\u0435 Windows 10.
