Samba 4 is a multifunctional server product that also provides a file server, printing service, and identity server (winbind).<\/p>\n<p>Key <noindex><a rel=\"nofollow\" href=\"http:\/\/www.samba.org\/samba\/history\/samba-4.12.0.html\">changes<\/a><\/noindex> In Samba 4.12:<\/p>\n<ul>\n<li class=\"l\"> The embedded implementations of cryptographic functions have been removed from the codebase in favor of using external libraries. It has been decided to use GnuTLS as the main cryptographic library (version 3.4.7 or higher is required). In addition to reducing potential threats related to vulnerabilities discovered in the embedded implementations of cryptographic algorithms, the transition to GnuTLS has also significantly improved performance when using encryption in SMB3. Testing with the CIFS client implementation from Linux kernel 5.3 showed a 3-fold increase in write speed and a 2.5-fold increase in read speed.\n<li class=\"l\"> A new backend for searching SMB shares using the protocol <noindex><a rel=\"nofollow\" href=\"https:\/\/wiki.samba.org\/index.php\/Spotlight\">Spotlight<\/a><\/noindex>, based on the search engine  <noindex><a rel=\"nofollow\" href=\"https:\/\/www.elastic.co\/elasticsearch\">Elasticsearch<\/a><\/noindex> (previously provided by the backend based on <noindex><a rel=\"nofollow\" href=\"https:\/\/wiki.gnome.org\/Projects\/Tracker\">GNOME Tracker<\/a><\/noindex>). The package also includes the utility &#171;mdfind&#187; with a client implementation that allows sending search queries to any SMB server running the Spotlight RPC service. The default setting for &#171;spotlight backend&#187; has been changed to &#171;noindex&#187; (for Tracker or Elasticsearch, the values &#171;tracker&#187; or &#171;elasticsearch&#187; should be set explicitly).\n<li class=\"l\"> The behavior of the &#8216;net ads kerberos pac save&#8217; and &#8216;net eventlog export&#8217; operations has been changed; they now do not overwrite the file, and an error is returned if there is an attempt to export to an existing file.\n<li class=\"l\"> The samba-tool has improved the addition of contact entries for group members. Previously, the &#8216;samba-tool group addmembers&#8217; command could only add users, groups, and computers as new group members, but now it supports adding contacts as group members.\n<li class=\"l\"> The samba-tool now allows filtering by organizational units (OU) or subtrees. New flags &#171;&#8212;base-dn&#187; and &#171;&#8212;member-base-dn&#187; have been added, enabling operations to be performed only within a specific part of the Active Directory tree, such as only within a single OU.\n<li class=\"l\"> A new VFS module &#8216;io_uring&#8217; has been added, utilizing the new Linux kernel interface <noindex><a rel=\"nofollow\" href=\"http:\/\/kernel.dk\/io_uring.pdf\">io_uring<\/a><\/noindex> for asynchronous input\/output. Io_uring supports input\/output polling and can work with buffering (the previously proposed &#171;aio&#187; mechanism did not support buffered input\/output). When using polling, io_uring significantly outperforms aio. Currently, Samba has implemented support for SMB_VFS_{PREAD,PWRITE,FSYNC}_SEND\/RECV based on io_uring, and reduced the overhead of maintaining a thread pool in user space when applying the default VFS backend. To build the &#8216;io_uring&#8217; VFS module, the library is required <noindex><a rel=\"nofollow\" href=\"https:\/\/git.kernel.dk\/cgit\/liburing\/\">liburing<\/a><\/noindex> and Linux kernel 5.1+.\n<li class=\"l\"> The VFS provides the ability to specify a special value of UTIME_OMIT to mark the need to ignore time in the SMB_VFS_NTIMES() function.\n<li class=\"l\"> Support for the &#171;write cache size&#187; parameter has been discontinued in smb.conf, which has become meaningless with the support of io_uring.\n<li class=\"l\"> In Samba-DC and Kerberos, support for encryption using the DES algorithm has been discontinued. 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 became obsolete.\n<li class=\"l\"> The BIND9_FLATFILE backend has been declared obsolete and will be removed in one of the upcoming releases.\n<li class=\"l\"> The zlib library has been included in the build dependencies. The built-in implementation of zlib has been removed from the codebase (the code was based on an old version of zlib, which had encryption support issues).\n<li class=\"l\"> Fuzz testing of the codebase has been established, including in the service<br \/>\noss-fuzz. During fuzz testing, many bugs were discovered and fixed.<\/p>\n<li class=\"l\"> The minimum Python version requirements have been raised from Python<br \/>\n3.4 to Python 3.5. The ability to build the file server with Python 2 is still preserved (before running .&#x2F;configure&#8217; and &#8216;make&#8217;, set the environment variable &#8216;PYTHON=python2&#8217;).<\/p>\n<\/ul>\n<p><noindex><a rel=\"nofollow\" name=\"link\"><\/a><\/noindex><\/p>\n<p>Source: <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.
