  1. Release notes for FreeBSD 13.0.
  2. This file describes new user-visible features, changes and updates relevant to
  3. users of binary FreeBSD releases. Each entry should describe the change in no
  4. more than several sentences and should reference manual pages where an
  5. interested user can find more information. Entries should wrap after 80
  6. columns. Each entry should begin with one or more commit IDs on one line,
  7. specified as a comma separated list and/or range, followed by a colon and a
  8. newline. Entries should be separated by a newline.
  9. Changes to this file should not be MFCed.
  10. r355677:
  11. Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
  12. (RFC-8276) to the NFS client and server.
  13. NFSv4.2 is comprised of several optional features that can be supported
  14. in addition to NFSv4.1. This patch adds the following optional features:
  15. - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
  16. - posix_fallocate()
  17. - intra server file range copying via the copy_file_range(2) syscall
  18. --> Avoiding data tranfer over the wire to/from the NFS client.
  19. - lseek(SEEK_DATA/SEEK_HOLE)
  20. - Extended attribute syscalls for "user" namespace attributes as defined
  21. by RFC-8276.
  22. For the client, NFSv4.2 is only used if the mount command line option
  23. minorversion=2 is specified.
  24. For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
  25. and vfs.nfsd.server_max_minorversion4 have been added that allow
  26. sysadmins to limit the minor versions of NFSv4 supported by the nfsd
  27. server.
  28. Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
  29. on the server.
  30. r354517:
  31. iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
  32. r354269:
  33. sqlite3 is updated to sqlite3-3.30.1.
  34. r352668:
  35. cron(8) now supports the -n (suppress mail on succesful run) and -q
  36. (suppress logging of command execution) options in the crontab format.
  37. See the crontab(5) manpage for details.
  38. r352304:
  39. ntpd is no longer by default locked in memory. rlimit memlock 32
  40. or rlimit memlock 0 can be used to restore this behaviour.
  41. r351522:
  42. Add kernel-side support for in-kernel Transport Layer Security
  43. (KTLS). KTLS permits using sendfile(2) over sockets using
  44. TLS.
  45. r351397:
  46. WPA is updated from 2.8 to 2.9.
  47. r351361:
  48. Add probes for lockmgr(9) to the lockstat DTrace provider, add
  49. corresponding lockstat(1) events, and document the new probes in
  50. dtrace_lockstat.4.
  51. r351356:
  52. Intel RST is a new 'feature' that remaps NVMe devices from
  53. their normal location to part of the AHCI bar space. This
  54. will eliminate the need to set the BIOS SATA setting from RST
  55. to AHCI causing the nvme drive to be erased before FreeBSD
  56. will see the nvme drive. FreeBSD will now be able to see the
  57. nvme drive now in the default config.
  58. r351201, r351372:
  59. Add a vop_stdioctl() call, so that file systems that do not support
  60. holes will have a trivial implementation of lseek(SEEK_DATA/SEEK_HOLE).
  61. The algorithm appears to be compatible with the POSIX draft and
  62. the implementation in Linux for the case of a file system that
  63. does not support holes. Prior to this patch, lseek(2) would reply
  64. -1 with errno set to ENOTTY for SEEK_DATA/SEEK_HOLE on files in
  65. file systems that do not support holes.
  66. r351372 maps ENOTTY to EINVAL for lseek(SEEK_DATA/SEEK_HOLE) for
  67. any other cases, such as a ENOTTY return from vn_bmap_seekhole().
  68. r350665:
  69. The fuse driver has been renamed to fusefs(5) and been substantially
  70. rewritten. The new driver includes many bug fixes and performance
  71. enhancements, as well as the following user-visible features:
  72. * Optional kernel-side permissions checks (-o default_permissions)
  73. * mknod(2), socket(2), and pipe(2) support
  74. * server side locking with fcntl(2)
  75. * FUSE operations are now interruptible when mounted with -o intr
  76. * server side handling of UTIME_NOW during utimensat(2)
  77. * mount options may be updated with "mount -u"
  78. * fusefs file system may now be exported over NFS
  79. * RLIMIT_FSIZE support
  80. * support for fuse file systems using protocols as old as 7.4
  81. FUSE file system developers should also take note of the following new
  82. features:
  83. * The protocol level has been raised from 7.8 to 7.23
  84. * kqueue support on /dev/fuse
  85. * server-initiated cache invalidation via FUSE_NOTIFY_REPLY
  86. r350471:
  87. gnop(8) can now configure a delay to be applied to read and write
  88. request delays. See the -d, -q and -x parameters.
  89. r350315, r350316:
  90. Adds a Linux compatible copy_file_range(2) syscall.
  91. r350307:
  92. libcap_random(3) has been removed. Applications can use native
  93. APIs to get random data in capability mode.
  94. r349529,r349530:
  95. Add support for using unmapped mbufs with sendfile(2).
  96. r349352:
  97. nand(4) and related components have been removed.
  98. r349349:
  99. The UEFI loader now supports HTTP boot.
  100. r349335:
  101. bhyve(8) now implements a High Definition Audio (HDA) driver, allowing
  102. guests to play to and record audio data from the host.
  103. r349286:
  104. swapon(8) can now erase a swap device immediately before enabling it,
  105. similar to newfs(8)'s -E option. This behaviour can be specified by
  106. adding -E to swapon(8)'s command-line parameters, or by adding the
  107. "trimonce" option to a swap device's /etc/fstab entry.
  108. r347908-r347923:
  109. The following network drivers have been removed: bm(4), cs(4), de(4),
  110. ed(4), ep(4), ex(4), fe(4), pcn(4), sf(4), sn(4), tl(4), tx(4), txp(4),
  111. vx(4), wb(4), xe(4).
