------------------------------------------------------------------------ - OpenBSD 7.5 RELEASED ------------------------------------------------- April 5, 2024. We are pleased to announce the official release of OpenBSD 7.5. This is our 56th release. We remain proud of OpenBSD's record of more than twenty years with only two remote holes in the default install. As in our previous releases, 7.5 provides significant improvements, including new features, in nearly all areas of the system: - Various kernel improvements: o Added bt(5) and btrace(8) support for binary modulo operator ('%'). o Added a TIMEOUT_MPSAFE flag to timeout(9). o Added IBM encoded version of the "Spleen 8x16" font, usable as console font. o Cleanup and machine-independent refactoring of three context switch paths outside of mi_switch(): when a process forks and the new proc needs to be scheduled by proc_trampoline, cpu_hatch: when booting APs, and sched_exit: when a proc exits. o Made vscsi(4) 'vscsi_filtops' mpsafe and extended the 'sc_state_mtx' mutex(9) to protect 'sc_klist' knotes list. o Made out-of-swap checking more robust, preventing potential deadlocks. o Eliminated the ioctl whitelist that bio(4) will tunnel for other devices, allowing bio to be used with other (non-raid) related devices. o On msdos filesystems, ensure that a complete struct fsinfo is read even if the filesystem sectors are smaller. o Implemented per-CPU caching for the page table page (vp) pool and the PTE descriptor (pted) pool in the arm64 pmap implementation. This significantly reduces the side-effects of lock contention on the kernel map lock and leads to significant speedups on machines with many CPU cores. o Implemented acpi(4) RootPathString support in the LoadTable() AML function, fixing OpenBSD boot on an older version of Hyper-V. o Fixed Linux NFS clients freezing after five minutes of inactivity. o Fixed core file writing when a file map into memory has later been truncated to be smaller than the mapping. o Disallow madvise(2) and msync(2) memory/mapping destructive operations on immutable memory regions. Instead return EPERM. o Added new amd64-only sysctl machdep.retpoline which says whether the cpu requires the retpoline branch target injection mitigation. o Added new accounting flag ABTCFI to acct(5) to indicate SIGILL + code ILL_BTCFI has occurred in the process. - SMP Improvements o Some network timers run without kernel lock. o TCP syn cache timer runs with shared net lock. o bind(2) and connect(2) system calls can run in parallel. o Packet counter for lo(4) loopback interface are MP safe. o Split protocol control block table for UDP into IPv4 and IPv6 tables to allow concurrent access. o UDP packets can be sent in parallel by multiple threads. - Direct Rendering Manager and graphics drivers o Updated drm(4) to Linux 6.6.19. o New apldcp(4) and apldrm(4) drivers for Apple display coprocessor. - VMM/VMD improvements o Fixed IRQ storm caused by edge-triggered devices such as the UART. o Fixed block size calculation for vioscsi devices. o Added io instruction length to vm exit information, allowing vmd(8) to perform validation in userspace. o Adopted new imsg_get_*(3) api. o Rewrote vionet devices to allow zero-copy data transfers between host and guest. o Improved error messages related to getgrnam(3) usage and out of tap(4) device conditions. o Fixed various things found by smatch static analyzer. o Fixed various file descriptor lifecycle issues and leaks across fork(2)/ execve(2) usage. o Added multi-threading support to vionet device emulation, improving latency. o Fixed vmm(4) instability on Intel VMX hosts by updating GDTR & TR if vcpu moves host cpus. o Added EPT flushing upon vmm(4) enabling VMX mode. o Added branch predictor flushing if IBPB is supported. o Corrected restoring GDTR and IDTR limits upon VMX guest exit. o Corrected handling of CPUID 0xd subleaves o Added additional use of VERW and register clobbering to mitigate RFDS vulnerabilities on Intel Atom cores. - Various new userland features: o Made malloc(3) save backtraces to show in leak dump with depth of backtrace set via malloc option D (aka 1), 2, 3 or 4. o Added support for cksum(1) -c checking base64 digests in reverse mode. o Added kdump(1) [-p program] to filter dumps by basename. o Made ps(1) accept numerical user IDs. o Built and provide the tzdata.zi and leap-seconds.list files from zoneinfo. Some third-party software now expects these files to be installed. Provide the zonenow.tab file, a table where each row stands for a timezone where civil timestamps are predicted to agree from now on. o Added basic write support for pax(1) format archives. o Added 'pax' format support for files over 8GB to tar(1). o Added 'pax' format support for mtime and atime to tar(1). o Extended imsg and the ibuf buffer manipulation API with useful getter methods. Unified file descriptor passing in all imsg using programs with the use of the imsg_get_fd() function. o Added mkdtemps(3), identical to mkdtemp(3) except that it permits a suffix to exist in the template. o Added mktemp(1) suffix support for compatibility with the GNU version. It is now possible to use templates where the Xs are not at the end. - Various bugfixes and tweaks in userland: o Silenced list of specific firmware not needing update in pkg_add(1). o Improved ls(1) horizontal alignment in long format. o Added bioctl(8) retry on empty passphrase. o Fixed unveil(2) in patch(1) with explicit patchfile. o Made gnu99 the default for gcc 3.3.6 and 4.2.1 rather than defaulting to gnu89. o Enhanced fdisk(8) 'flag' to accept hex values. o Prevented fdisk(8) 'flag' from altering other GPT partition attributes when flagging a partition as the only bootable partition. o Allow fdisk(8) to add GPT partitions of protected types, making it possible to provision virtual machine images that need a "BIOS Boot" partition. o Added group handling matching fbtab(5) to xenodm. o Made grep(1) -m behavior match GNU grep. o Tweaked the default memory limits in /etc/login.conf on several architectures to account for increased memory requirements, for example when compiling or linking under user pbuild. o Initialize all terminals with "tset -I", thereby avoiding extra newlines to be printed. o Added mkhybrid(8) '-e' (-eltorito-boot-efi) option for writing an EFI eltorito boot image, in addition to or instead of the x86 boot image, to the output file. o Added openrsync(1) --omit-dir-times (-O) to omit directories from --times, as well as --no-O and --no-omit-dir-times options for compatibility. o Implemented openrsync(1) --omit-link-times (-J) option to omit symlinks from --times. o Added accounting flag and lastcomm(1) report for syscall pinning violations. o Added ktrace(1) and kdump(1) support to observe pinsyscall(2) violations. o Changed ftp(1) to avoid use of the interactive shell if -o is given. o Moved non-daemon services to run in a different rc(8) process group to avoid SIGHUP at boot. o Changed ld.so(1) to only load the first libc version encountered requested and substituting it for all further loads, ensuring that the libc version requested by an executable itself is the one loaded. o Significantly (for small programs) reduce the size of statically linked binaries by splitting several libc internal functions into separate compilation and thus linkage units. Specifically getpwnam(3) does not need the full YP socket setup and does not use all possible dbopen(3) database backends. o Added vi(1) showfilename set option to display the file name in the lower left corner. o Added backup of disklabel for softraid(4) chunks to security(8). - Improved hardware support and driver bugfixes, including: o New ampchwm(4) driver for Ampere Altra power telemetry. o New rkspi(4) driver for Rockchip SPI controller. o Support for RK806 PMIC in rkpmic(4). o Support for Allwinner H616 in sxisyscon(4), sxiccmu(4), sxipio(4), sximmc(4) and ehci(4). o Support for Allwinner D1 in sxidog(4), sxiccmu(4), sxipio(4), sximmc(4) and ehci(4). o Support for Aero and Sea SAS HBAs in mpii(4). o Support for SAS3816 and SAS3916 in mfii(4). o In xbf(4), allowed Xen to use backing store devices with 4K-byte sectors. o Added fanpwr(4) support for the Rockchip RK8602 and RK8603 voltage regulators. o Support keyboard backlights on Apple Powerbooks. o Added operating performance point info about each arm64 cpu and expose the states of thermal zones as kstats(1). o Overhauled ugold(4) temperature sensor identification logic and added support for additional devices. o Made uthum(4) TEMPer{1,2} devices display negative degC. o Improve support for audio devices that via attach multiple uaudio(4) drivers. o In nvme(4) don't create sd(4) devices larger than the namespace. o Fix nvme(4) decoding of status fields. - New or improved network hardware support: o Utilize full checksum offload capabilities of vio(4) and vmx(4). o TCP Segmentation Offload (TSO) is also used in bnxt(4) and em(4). o Enabled TCP Segmentation Offload (TSO) in ixl(4). o The Synopsys Ethernet Quality-of-Service Controller (dwqe(4)) is enabled for amd64. o Added initial support for Elkhart Lake Ethernet to dwqe(4). o Support for AX88179A in axen(4). o Intel I225 and I226 Ethernet Controller igc(4) enabled for sparc64. o Allwinner EMAC Ethernet Controller dwxe(4) enabled for riscv64. o Corrected wrong register offset macros for dwqe(4) DMA burst length. o Fixed Tx watchdog trigger and freeze in dwqe(4). o Updated rge(4) microcode, initialization and reset behavior. o Prevented a potential bnxt(4) crash after failure to bring up a queue. - Added or improved wireless network drivers: o Introduce qwx(4), a port of the Linux ath11k driver for QCNFA765 devices. Available on the amd64 and arm64 platforms. o Fix Tx rate selection for management frames in iwx(4). o Fix iwx(4) loading the wrong firmware image on some devices. o Make bwfm(4) work with MAC addresses set via ifconfig lladdr. o Ensure that iwm(4) uses the 80MHz primary channel index announced in beacons. o Avoid using MCS-9 in iwm(4) Tx rate selection if 40 MHz is disabled to prevent firmware errors. o Ensure that iwm(4) and iwx(4) devices announce VHT capabilities in probe requests. o Fix bug in iwm(4), iwx(4), and iwn(4) which could result in some channels missing from scan results. o Enable iwm(4) on the arm64 platform. - IEEE 802.11 wireless stack improvements and bugfixes: o Ignore 40/80 MHz wide channel configurations which do not appear in the 802.11ac spec. This prevents device firmware errors which occurred when an access point announced an invalid channel configuration. - Installer, upgrade and bootloader improvements: o Add support for disk encryption in unattended installations with autoinstall(8), both with a plaintext passphrase or a keydisk. o Removed default sets answer in autoinstall(8) response file such that it now populates only with non-defaults. o Made fw_update(8) verify but not overwrite SHA256.sig. o Improved fw_update(8) output on errors and improved ftp error handling. o Added support in the installer to encrypt the root disk with a key disk. o Prevent re-starting the automatic upgrade on octeon and powerpc64, as is already done on other platforms. o Added CD install images to arm64. o Make the amd64 cdXX.iso and installXX.iso CD images bootable in EFI mode (by creating an EFI system partition containing the EFI boot loaders to be installed as an El Torito boot image). - Security improvements: o Introduce pinsyscalls(2): The kernel and ld.so(1) register the precise entry location of every system call used by a program, as described in the new ELF section .openbsd.syscalls inside ld.so and libc.so. ld.so uses the new syscall pinsyscalls(2) to tell the kernel the precise entry location of system calls in libc.so. Attempting to use a different system call entry instruction to perform a non-corresponding system call operation will fail and the process will be terminated with signal SIGABRT. o Removed support for syscall(2), the "indirection system call," a dangerous alternative entry point for all system calls. Together with pinsyscalls(2) this change makes it impossible to perform system call through any other way than the libc system call wrapper functions. Users of syscall(2), such as Perl and the Go programming language were converted to use the libc functions. o Added pledge(2) stdio before parsing pfkey messages to ipsecctl(8) -m and -s. o Tightened the pledge(2) in pax(1) in List and Append modes. o Created __OpenBSD versions of llvm cxa guard implementation using futex(2) with the correct number of arguments and without using syscall(2). o Improvements in Pointer Authentication (PAC) and Branch Target Identification (BTI) on arm64. - Changes in the network stack: o Enable IPv6 support in ppp(4) o Socket with sequenced packet type and control messages handle end of record correctly. o The routing table has a generation number. That means cached routes at sockets will be invalidated when the routing table changes. Especially with dynamic routing daemons local connections use the up to date route. o Route cache hits an misses are printed in netstat(1) statistics. o Prevented wg(4) getting stuck on peer destruction. o Made umb(4) delete any existing v4 address before setting a new one, allowing keeping of a working default route when the address changes. o Forwarded TCP LRO disabling to parent devices and disabled TCP LR0 on bridged vlan(4) and default for bpe(4), nvgre(4) and vxlan(4). o Fixed race between ifconfig(8) destroy of an interface and the ARP timer. o Added statistics counters for the route cache, reporting cache hits and misses. This is shown in netstat(1) with netstat -s. - The following changes were made to the pf(4) firewall: o tcpdump on pflog(4) interface shows packets dropped by the default rule with the "block" action. Although the default rules is a "pass" rule, it blocks malformed packets. Now this is correctly logged. o Adjustments to keep up firewall aware of MP related changes in the network stack. o Fix handling of multiple -K(-k) options in pfctl(8), so behavior matches what's described in manual. o Make pfctl(8) show all tables in all anchors with pfctl -a "*" -sT. o Added check to ensure pfctl(8) -f won't accept a directory and install an empty ruleset. o Added validation for IPv4 packet options in divert(4). - Routing daemons and other userland network improvements: o IPsec support was improved: - Made iked(8) always prefer group from the initial KE payload as responder if supported. - Corrected renewal of expired certificates in iked(8). - Added an iked(8) debug message when no policy is found. - Implemented a per connection peerid for iked(8) control replies. - Made iked(8) trigger retransmission only for fragment 1/x to prevent each received fragment triggering retransmission of the full fragment queue. - Prevent routing loops by dropping already encrypted packets that are going through sec(4) again. o In bgpd(8), - Rewrite the internal message passing mechanism to use a new memory-safe API. - Rewrite most protocol parsers to use the new memory-safe API. Convert the UPDATE parser, all of RTR, as well as both the MRT dump code in bgpd and the parser in bgpctl. - Improve RTR logging, error handling and version negotiation. o rpki-client(8) saw these and more changes: - Add ability to constrain an RPKI Trust Anchor's effective signing authority to a limited set of Internet numbers. This allows Relying Parties to enjoy the potential benefits of assuming trust, but within a bounded scope. - Following a 'failed fetch' (described in RFC 9286), emit a warning and continue with a previously cached Manifest file. - Emit a warning when the remote repository presents a Manifest with an unexpected manifestNumber. - Improved CRL extension checking. - Experimental support for the P-256 signature algorithm. - A failed manifest fetch could result in a NULL pointer dereference or a use after free. - Reject non-conforming RRDP delta elements that contain neither publish nor a withdraw element and fall back to the RRDP snapshot. - Refactoring and minor bug fixes in the warning display functions. - The handling of manifests fetched via rsync or RRDP was reworked to fully conform to RFC 9286. - Fix a race condition between closing an idle connection and scheduling a new request on it. - The evaluation time specified with -P now also applies to trust anchor certificates. - Check that the entire CMS eContent was consumed. Previously, trailing data would be silently discarded on deserialization of products. - In file mode do not consider overclaiming intermediate CA certificates as invalid. OAA warning is still issued. - Print the revocation time of certificates in file mode. - Be more careful when converting OpenSSL numeric identifiers (NIDs) to strings. - Added support for RPKI Signed Prefix Lists. - Added an -x flag to opt into parsing and evaluation of file types that are still considered experimental. - Added a metric to track the number of new files that were moved to the validated cache. - Ensure that the FileAndHashes list in a Manifest contains no duplicate file names and no duplicate hashes. o In smtpd(8), - Add Message-Id as needed for messages received on the submission port. - Added support for RFC 7505 "Null MX" handling and treat an MX of "localhost" as it were a "Null MX". - Allow inline tables and filter listings in smtpd.conf(5) to span over multiple lines. - Enabled DSN for the implicit socket too. - Added the no-dsn option for listen on socket too. - Reject headers that start with a space or a tab. - Fixed parsing of the ORCPT parameter. - Fixed table lookups of IPv6 addresses. - Fixed handling of escape characters in To, From and Cc headers. - Run LMTP deliveries as the recipient user again. - Disallow custom commands and file reading in root's .forward file. - Do not process other users .forward files when an alternate delivery user is provided in a dispatcher. - Unify the table(5) parser used in smtpd(8) and makemap(8). - Allow to use table(5) mappings on various match constraints. o Many other changes in various network programs and libraries: - If a DNS name is configured as remote syslog server, syslogd(8) retries to resolve the loghost name periodically until it succeeds. UDP packets that get lost during that period are counted and logged later. - Added counting of dropped UDP packets to syslogd(8). - Prevented use after free of TLS context at syslogd(8) shutdown. - Introduced dhcpd(8) log output to stderr and '-v' option to make this output more verbose. - In dhcpd(8), made dhcp-options(5) recognize option ipv6-only-preferred (RFC8925). - Allowed dhcpleased(8) to request "IPv6-only preferred" and deconfigure IPv4 on the interface if the server replies with this option. - Fixed radiusd(8) to properly fixup MPPE-{Send,Recv}-Key and Tunnel-Password attributes of the response. - Added nochroot parameter to radiusd(8) module_drop_privilege() so that modules can use unveil(2) instead of chroot(2) if needed. - Ensured correct denominators when converting NTP fixed point values to double and vice-versa in ntpd(8). - In the resolver, do not short-circuit resolution of localhost when AI_NUMERICHOST is set. Ensure that a proper string is returned by getaddrinfo(3) when AI_CANONNAME or AI_FQDN is set. - Added ifconfig(8) support for specifying ports on the src address in tunnel endpoints of gif(4), gre(4) and related tunnel interfaces. - Added an ifconfig(8) endpoint command for "bridges" that use addresses as endpoints, usable to add static entries on interfaces like vxlan(4). - Tightened up relayd(8) HTTP header parsing. - Deferred relayd(8) relay_read_http header parsing until after line continuation, preventing potential request smuggling attacks. - Improved httpd(8) auto-index, adding human-readable file sizes and allowing per-column sorting. - Switched to using whois.internic.net for whois(1) -i. - tmux(1) improvements and bug fixes: o Made tmux(1) unzoom a window at the start of destroy so it doesn't happen later after the layout has been freed. o Prevented tmux(1) use of combined UTF-8 characters that are too long. o Corrected tmux(1) handling of window ops with no pane. o Removed flags from the prefix before comparing with the received key so that tmux(1) modifier keys with flags work correctly. o Increased buffer size to avoid truncating styles in tmux(1). o Added two new values for the tmux(1) destroy-unattached option to destroy sessions only if they are not members of sessions groups. - LibreSSL version 3.9.0 o Portable changes - libcrypto no longer exports compat symbols in cmake builds. - Most compatibility symbols are prefixed with libressl_ to avoid symbol clashes in static links. - Fixed various warnings on Windows. - Removed assert pop-ups with Windows debug builds. - Fixed crashes and hangs in Windows ARM64 builds. - Improved control-flow enforcement (CET) support. o Internal improvements - Converted uses of OBJ_bsearch_() to standard bsearch(3). - Greatly simplified by_file_ctrl(). - Simplified and cleaned up the OBJ_ API. - Cleaned up the EVP_Cipher{Init,Update,Final}(3) implementations. - Removed unused function pointers from X.509 stores and contexts. - A lot of cleanup and reorganization in EVP. - Removed all remaining ENGINE tentacles. - Simplified internals of X509_TRUST handling. - Made deletion from a lhash doall callback safe. - Rewrote BIO_dump*(3) internals to be less bad. o Documentation improvements - ENGINE documentation was updated to reflect reality. - Made EVP API documentation more accurate and less incoherent. - Call out some shortcomings of the EC_KEY_set_* API explicitly. o Testing and proactive security - Bug fixes and simplifications in the Wycheproof tests. o Compatibility changes - Added ChaCha20 and chacha20 aliases for ChaCha. - SSL_library_init(3) now has the same effect as OPENSSL_init_ssl(). - EVP_add_{cipher,digest}() were removed. From the OBJ_NAME API, only OBJ_NAME_do_all*() remain. In particular, it is no longer possible to add aliases for ciphers and digests. - The thread unsafe global tables are no longer supported. It is no longer possible to add aliases for ciphers and digests, custom ASN.1 strings table entries, ASN.1 methods, PKEY methods, digest methods, CRL methods, purpose and trust identifiers, or X.509 extensions. - Removed the _cb() and _fp() versions of BIO_dump{,_indent}(). - BIO_set() was removed. - BIO_{sn,v,vsn}printf() were removed. - Turn the long dysfunctional openssl(1) s_client -pause into a noop. - openssl(1) x509 now supports -new, -force_pubkey, -multivalue-rdn, -set_issuer -set_subject, and -utf8. - Support ECDSA with SHA-3 signature algorithms. - Support HMAC with truncated SHA-2 and SHA-3 as PBE PRF. - GOST and STREEBOG support was removed. - CRYPTO_THREADID, _LHASH, _STACK and X509_PURPOSE are now opaque, X509_CERT_AUX and X509_TRUST were removed from the public API. - ASN1_STRING_TABLE_get(3) and X509_PURPOSE_get0*(3) now return const pointers. - EVP_{CIPHER,MD}_CTX_init()'s signatures and semantics now match OpenSSL's behavior. - sk_find_ex() and OBJ_bsearch_() were removed. - CRYPTO_malloc(3) was fixed to use size_t argument. CRYPTO_malloc() and CRYPTO_free() now accept file and line arguments. - A lot of decrepit CRYPTO memory API was removed. o Bug fixes - Fixed aliasing issues in BN_mod_exp_simple() and BN_mod_exp_recp(). - Fixed numerous misuses of X509_ALGOR_set0(3) resulting in leaks and potentially incorrect encodings. - Fixed potential double free in X509v3_asid_add_id_or_range(3). - Stopped using ASN1_time_parse() outside of libcrypto. - Prepared OPENSSL_gmtime(3) and OPENSSL_timegm(3) as public API wrappers of internal functions compatible with BoringSSL API. - Removed print_bin() to avoid overwriting the stack with 5 bytes of " " when ECPK parameters are printed with large indentation. - Avoid a NULL dereference after memory allocation failure during TLS version downgrade. - Fixed various bugs in CMAC internals. - Fixed 4-byte overreads in GHASH assembly on amd64 and i386. - Fixed various NULL dereferences in PKCS #12 code due to mishandling of OPTIONAL content in PKCS #7 ContentInfo. - Aligned SSL_shutdown(3) behavior in TLSv1.3 with the legacy stack. - Fixed the new X.509 verifier to find trust anchors in the trusted stack. - OpenSSH 9.6 and OpenSSH 9.7 o Security fixes - ssh(1), sshd(8): implement protocol extensions to thwart the so-called "Terrapin attack" discovered by Fabian Bäumer, Marcus Brinkmann and Jörg Schwenk. This attack allows a MITM to effect a limited break of the integrity of the early encrypted SSH transport protocol by sending extra messages prior to the commencement of encryption, and deleting an equal number of consecutive messages immediately after encryption starts. A peer SSH client/server would not be able to detect that messages were deleted. While cryptographically novel, the security impact of this attack is fortunately very limited as it only allows deletion of consecutive messages, and deleting most messages at this stage of the protocol prevents user authentication from proceeding and results in a stuck connection. The most serious identified impact is that it lets a MITM to delete the SSH2_MSG_EXT_INFO message sent before authentication starts, allowing the attacker to disable a subset of the keystroke timing obfuscation features introduced in OpenSSH 9.5. There is no other discernable impact to session secrecy or session integrity. - ssh-agent(1): when adding PKCS#11-hosted private keys while specifying destination constraints, if the PKCS#11 token returned multiple keys then only the first key had the constraints applied. Use of regular private keys, FIDO tokens and unconstrained keys are unaffected. - ssh(1): if an invalid user or hostname that contained shell metacharacters was passed to ssh(1), and a ProxyCommand, LocalCommand directive or "match exec" predicate referenced the user or hostname via %u, %h or similar expansion token, then an attacker who could supply arbitrary user/hostnames to ssh(1) could potentially perform command injection depending on what quoting was present in the user-supplied ssh_config(5) directive. OpenSSH 9.6 now bans most shell metacharacters from user and hostnames supplied via the command-line. This countermeasure is not guaranteed to be effective in all situations, as it is infeasible for ssh(1) to universally filter shell metacharacters potentially relevant to user-supplied commands. User/hostnames provided via ssh_config(5) are not subject to these restrictions, allowing configurations that use strange names to continue to be used, under the assumption that the user knows what they are doing in their own configuration files. o New features - ssh(1), sshd(8): add a "global" ChannelTimeout type that watches all open channels and will close all open channels if there is no traffic on any of them for the specified interval. This is in addition to the existing per-channel timeouts added recently. This supports situations like having both session and x11 forwarding channels open where one may be idle for an extended period but the other is actively used. The global timeout could close both channels when both have been idle for too long. - All: make DSA key support compile-time optional, defaulting to on. o Bugfixes - sshd(8): don't append an unnecessary space to the end of subsystem arguments (bz3667) - ssh(1): fix the multiplexing "channel proxy" mode, broken when keystroke timing obfuscation was added. (GHPR#463) - ssh(1), sshd(8): fix spurious configuration parsing errors when options that accept array arguments are overridden (bz3657). - ssh-agent(1): fix potential spin in signal handler (bz3670) - Many fixes to manual pages and other documentation, including GHPR#462, GHPR#454, GHPR#442 and GHPR#441. - Greatly improve interop testing against PuTTY. - Ports and packages: o Pre-built packages are available for the following architectures on the day of release: - aarch64 (arm64): 12145 - amd64: 12309 - i386: 10830 - mips64: 8674 - powerpc64: 8469 - riscv64: 10508 - sparc64: 9432 o Packages for the following architectures will be made available as their builds complete: - arm - powerpc - Some highlights: o Asterisk 16.30.1, 18.21.0 and o Mozilla Thunderbird 115.8.1 20.6.0 o Mutt 2.2.13 and NeoMutt 20240201 o Audacity 3.4.2 o Node.js 18.19.1 o CMake 3.28.3 o OCaml 4.14.1 o Chromium 122.0.6261.111 o OpenLDAP 2.6.7 o Emacs 29.2 o PHP 7.4.33, 8.0.30, 8.1.27, o FFmpeg 4.4.4 8.2.16 and 8.3.3 o GCC 8.4.0 and 11.2.0 o Postfix 3.8.6 o GHC 9.6.4 o PostgreSQL 16.2 o GNOME 45 o Python 2.7.18, 3.9.18, 3.10.13 o Go 1.22.1 and 3.11.8 o JDK 8u402, 11.0.22, 17.0.10 o Qt 5.15.12 (+ kde patches) and and 21.0.2 6.6.1 o KDE Applications 23.08.4 o R 4.2.3 o KDE Frameworks 5.115.0 o Ruby 3.1.4, 3.2.3 and 3.3.0 o KDE Plasma 5.27.10 o Rust 1.76.0 o Krita 5.2.2 o SQLite 3.44.2 o LLVM/Clang 13.0.0, 16.0.6 and o Shotcut 23.07.29 17.0.6 o Sudo 1.9.15.5 o LibreOffice 24.2.1.2. o Suricata 7.0.3 o Lua 5.1.5, 5.2.4, 5.3.6 and o Tcl/Tk 8.5.19 and 8.6.13 5.4.6 o TeX Live 2023 o MariaDB 10.9.8 o Vim 9.1.139 and Neovim 0.9.5 o Mono 6.12.0.199 o Xfce 4.18.1 o Mozilla Firefox 123.0.1 and ESR 115.8.0 - As usual, steady improvements in manual pages and other documentation. - The system includes the following major components from outside suppliers: o Xenocara (based on X.Org 7.7 with xserver 21.1.11 + patches, freetype 2.13.0, fontconfig 2.14.2, Mesa 23.1.9, xterm 378, xkeyboard-config 2.20, fonttosfnt 1.2.3, and more) o LLVM/Clang 16.0.6 (+ patches) o GCC 4.2.1 (+ patches) and 3.3.6 (+ patches) o Perl 5.36.3 (+ patches) o NSD 4.8.0 o Unbound 1.18.0 o Ncurses 5.7 o Binutils 2.17 (+ patches) o Gdb 6.3 (+ patches) o Awk January 22, 2024 version o Expat 2.6.0 o zlib 1.3.1 (+ patches) ------------------------------------------------------------------------ - SECURITY AND ERRATA -------------------------------------------------- We provide patches for known security threats and other important issues discovered after each release.

We hope our quality software will result in contributions that maintain our build/development infrastructure, pay our electrical/internet costs, and allow us to continue operating very productive developer hackathon events. All of our developers strongly urge you to donate and support our future efforts. Donations to the project are highly appreciated, and are described in more detail at: https://www.OpenBSD.org/donations.html ------------------------------------------------------------------------ - OPENBSD FOUNDATION --------------------------------------------------- For those unable to make their contributions as straightforward gifts, the OpenBSD Foundation (https://www.openbsdfoundation.org) is a Canadian not-for-profit corporation that can accept larger contributions and issue receipts. In some situations, their receipt may qualify as a business expense write-off, so this is certainly a consideration for some organizations or businesses. There may also be exposure benefits since the Foundation may be interested in participating in press releases. In turn, the Foundation then uses these contributions to assist OpenBSD's infrastructure needs. Contact the foundation directors at directors@openbsdfoundation.org for more information. ------------------------------------------------------------------------ - HTTPS INSTALLS ------------------------------------------------------- OpenBSD can be easily installed via HTTPS downloads. Typically you need a single small piece of boot media (e.g., a USB flash drive) and then the rest of the files can be installed from a number of locations, including directly off the Internet. Follow this simple set of instructions to ensure that you find all of the documentation you will need while performing an install via HTTPS. 1) Read either of the following two files for a list of HTTPS mirrors which provide OpenBSD, then choose one near you: https://www.OpenBSD.org/ftp.html https://ftp.openbsd.org/pub/OpenBSD/ftplist As of April 5, 2024, the following HTTPS mirror sites have the 7.5 release: https://cdn.openbsd.org/pub/OpenBSD/7.5/ Global https://ftp.eu.openbsd.org/pub/OpenBSD/7.5/ Stockholm, Sweden https://ftp.hostserver.de/pub/OpenBSD/7.5/ Frankfurt, Germany https://ftp.bytemine.net/pub/OpenBSD/7.5/ Oldenburg, Germany https://ftp.fr.openbsd.org/pub/OpenBSD/7.5/ Paris, France https://mirror.aarnet.edu.au/pub/OpenBSD/7.5/ Brisbane, Australia https://ftp.usa.openbsd.org/pub/OpenBSD/7.5/ CO, USA https://ftp5.usa.openbsd.org/pub/OpenBSD/7.5/ CA, USA https://mirror.esc7.net/pub/OpenBSD/7.5/ TX, USA https://openbsd.cs.toronto.edu/pub/OpenBSD/7.5/ Toronto, Canada https://cloudflare.cdn.openbsd.org/pub/OpenBSD/7.5/ Global https://fastly.cdn.openbsd.org/pub/OpenBSD/7.5/ Global The release is also available at the master site: https://ftp.openbsd.org/pub/OpenBSD/7.5/ Alberta, Canada However it is strongly suggested you use a mirror. Other mirror sites may take a day or two to update. 2) Connect to that HTTPS mirror site and go into the directory pub/OpenBSD/7.5/ which contains these files and directories. This is a list of what you will see: ANNOUNCEMENT armv7/ octeon/ root.mail README hppa/ openbsd-75-base.pub sparc64/ SHA256 i386/ packages/ src.tar.gz SHA256.sig landisk/ packages-stable/ sys.tar.gz alpha/ loongson/ ports.tar.gz xenocara.tar.gz amd64/ luna88k/ powerpc64/ arm64/ macppc/ riscv64/ It is quite likely that you will want at LEAST the following files which apply to all the architectures OpenBSD supports. README - generic README root.mail - a copy of root's mail at initial login. (This is really worthwhile reading). 3) Read the README file. It is short, and a quick read will make sure you understand what else you need to fetch. 4) Next, go into the directory that applies to your architecture, for example, amd64. This is a list of what you will see: BOOTIA32.EFI* bsd* floppy75.img pxeboot* BOOTX64.EFI* bsd.mp* game75.tgz xbase75.tgz BUILDINFO bsd.rd* index.txt xfont75.tgz INSTALL.amd64 cd75.iso install75.img xserv75.tgz SHA256 cdboot* install75.iso xshare75.tgz SHA256.sig cdbr* man75.tgz base75.tgz comp75.tgz miniroot75.img If you are new to OpenBSD, fetch _at least_ the file INSTALL.amd64 and install75.iso. The install75.iso file (roughly 684MB in size) is a one-step ISO-format install CD image which contains the various *.tgz files so you do not need to fetch them separately. If you prefer to use a USB flash drive, fetch install75.img and follow the instructions in INSTALL.amd64. 5) If you are an expert, follow the instructions in the file called README; otherwise, use the more complete instructions in the file called INSTALL.amd64. INSTALL.amd64 may tell you that you need to fetch other files. 6) Just in case, take a peek at: https://www.OpenBSD.org/errata.html This is the page where we talk about the mistakes we made while creating the 7.5 release, or the significant bugs we fixed post-release which we think our users should have fixes for. Patches and workarounds are clearly described there. ------------------------------------------------------------------------ - X.ORG FOR MOST ARCHITECTURES ----------------------------------------- X.Org has been integrated more closely into the system. This release contains X.Org 7.7. Most of our architectures ship with X.Org, including amd64, sparc64 and macppc. During installation, you can install X.Org quite easily using xenodm(1), our simplified X11 display manager forked from xdm(1). ------------------------------------------------------------------------ - PACKAGES AND PORTS --------------------------------------------------- Many third party software applications have been ported to OpenBSD and can be installed as pre-compiled binary packages on the various OpenBSD architectures. Please see https://www.openbsd.org/faq/faq15.html for more information on working with packages and ports. Note: a few popular ports, e.g., NSD, Unbound, and several X applications, come standard with OpenBSD and do not need to be installed separately. ------------------------------------------------------------------------ - SYSTEM SOURCE CODE --------------------------------------------------- The source code for all four subsystems can be found in the pub/OpenBSD/7.5/ directory: xenocara.tar.gz ports.tar.gz src.tar.gz sys.tar.gz The README (https://ftp.OpenBSD.org/pub/OpenBSD/7.5/README) file explains how to deal with these source files. ------------------------------------------------------------------------ - THANKS --------------------------------------------------------------- Ports tree and package building by Jeremie Courreges-Anglas, Visa Hankala, Stuart Henderson, Peter Hessler, George Koehler, Kurt Mosiejczuk, and Christian Weisgerber.
