RPM 6.0.0 ALPHA

What's Changed

Overview

• RPM defaults to enforcing signature checking (#1573)
• RPM uses the full key ID or fingerprint to identify OpenPGP keys everywhere (#2403)
• Support for multiple OpenPGP signatures per package (#3385)
• Support for updating previously imported keys (#2577)
• Support for both RPM v4 and v6 packages
• Support for installing RPM v3 packages has been removed (#1107)
• By default, RPM no longer verifies obsolete crypto (MD5, SHA1, DSA) (#1292)
• Man page overhaul (work in progress as of 6.0 alpha)
• Pristine and verifiable release tarballs (#3565) (#2702)

General Use

• Several enhancements to rpmkeys(8):
  • rpmkeys --import can now be used to update keys (#2577). This also updates the key handle from a short ambiguous key id to full fingerprint.
  • rpmkeys --export added for exporting keys
  • rpmkeys --checksig, --list, --delete use and expect full fingerprint of the keys (#3360)
  • rpmkeys works identically with all keystore backends
  • rpmkeys --rebuild can be used to rebuild the keystore contents and move between different keystore backends (#3347)
• Several enhancements to rpmsign(1):
  • rpmsign can use either GnuPG or Sequoia-sq for signing (controlled by %_openpgp_sign macro (gpg or sq))
  • rpmsign --addsign always adds a new signature (arbitrary number of signatures supported now)
  • rpmsign --resign replaces all existing signatures with a new one
• New query tag extensions (e.g. with --qf <format>):
  • rpmformat for determining package format version (3/4/6)
  • openpgp for managing all supported OpenPGP signature types
• New --filemime query alias for querying per-file MIME info
• Consistent terminology and case usage in signature and key messages
  • OpenPGP signatures are called OpenPGP in output
  • RPM v3 header+payload signatures are called "legacy" in output
• Man page overhaul (WIP):
  • Update all manual pages to a new consistent style (#3669)
  • Add man pages for all major components and file formats (#3612)
  • Move end-user commands to section 1
  • Many previously undocumented things covered, many errors fixed

Packaging

• rpmbuild(1) now supports generating two different package formats (controlled by %_rpmformat macro):
  • RPM v6
    • All file sizes and related limits are 64bit
    • Crypto modernization
    • MIME file info
    • Widely compatible with RPM >= 4.14
  • RPM v4
    • Bit-per-bit compatible with packages produced by RPM 4.x
• rpmbuild(1) can now automatically sign packages if %_openpgp_autosign_id macro is defined (#2678)
• New command rpm-setup-autosign(1) added for easy auto-signing configuration (#3522)
• New %{span:...} macro to make defining multi-line macros nicer
• New %{xdg:...} macro for evaluating XDG base directories

• New identifiers related to multiple signature support added:
  • RPMTAG_OPENPGP rpm tag
  • RPMSIGTAG_OPENPGP signature header tag (alias to RPMTAG_OPENPGP)
  • RPMVSF_NOOPENPGP verification flag
• New rpm tags: RPMTAG_PAYLOADSIZE, RPMTAG_PAYLOADSIZEALT, RPMTAG_RPMFORMAT, RPMTAG_FILEMIMEINDEX, RPMTAG_MIMEDICT, RPMTAG_FILEMIMES

• Eliminate various internal symbols accidentally leaking to the ABI
• Optimize rpmlog() locking

Building RPM

• A C++20 compiler is now required in addition to a C99 compiler, but C++20 modules support is not required.
• scdoc man page generator is now required for building RPM
• Pre-built API documentation is no longer shipped in the release tarballs. Building it is optional, but Doxygen is required for doing so. Pre-built API documentation for all releases can be found in https://ftp.rpm.org/api/

Compatibility Notes

Package format

• Support for installing RPM v3 packages has been removed. (#1107) They can still be queried and also unpacked with rpm2cpio(1).
• RPM v4 packages remain fully supported, but:
  • In the default configuration, packages built with RPM < 4.14.0 cannot be verified due to their use of weak, obsolete MD5 and SHA1 digests. For strongly signed packages, this can be worked around by changing %_pkgverify_level to signature so the weak digests are simply ignored. If verifying the weak digests is necessary, the RPM 4.x behavior can be restored by setting %_pkgverify_flags to 0.
• RPM v6 packages
  • Can be queried with RPM >= 4.6
  • Can be unpacked with RPM >= 4.12
  • Can be verified and installed with RPM >= 4.14 (with caveats/limitations)
• Lua posix.fork() family of calls, deprecated in 4.20, is disabled in packages built with RPM >= 6.0. They continue to function in packages built by RPM <= 4.20 however.

Other

• Package signing key configuration differs from the past. To support other implementations besides GnuPG, the signer ID is now set via %_openpgp_sign_id macro, which defaults to %{?_gpg_name} for backwards compatibility.
• The low-level package signing macros are now parametric, any custom %__gpg_sign_cmd overrides will simply not work as such. Users are encouraged to look into dropping such overrides rather than just updating, most such overrides haven't been necessary in a long time.
• %_passwd_path and %_group_path are now treated as colon separated paths to allow using multiple files as the source of NSS information (e.g. with nss-altfiles)
• --pkgid and --hdrid query sources CLI-switches have been dropped (#2633)

RPM 4.20.1

This is primarily a bugfix release addressing a handful of regressions in RPM 4.20.0 as well as various other issues.

What's Changed

Enhancements

• Packaging: Add support for fully locked user accounts (via the new u! flag) in sysusers.d(5) files (#3450).
• Building: RPM release tarballs (.tar.bz2) are now generated in a reproducible and hermetic environment using GitHub Actions (#2702).

Fixes

• Command-Line: Fix a regression where rpmsign(8) could corrupt the packages on signing operations (affected RPM >= 4.18.1) (#3469).
• Command-Line: Fix a regression where rpmspec(8) would emit extra output in query mode for BuildSystem specs (#3413).
• Command-Line: Fix rpmdb --exportdb failing when the database is on read-only media (#1266).
• Command-Line: Fix rpmkeys(8) failing when no keys are present in the keyring (#3378).
• Command-Line: It was possible to sign files in .src.rpm packages with rpmsign(8), which has been corrected (#3470).
• Transactions: Fix unmodified %config files (and possibly more if %_minimize_writes is enabled) being removed in case of an unpack failure (affected RPM >= 4.14.0) (#3284).
• Transactions: Fix sqlite rpmdb growing over time (#3309).
• Transactions: Lua deprecation warnings were also shown for packages built with an RPM version where the functions weren't yet deprecated, which has been corrected (#3270).
• Transactions: Packages without RPMTAG_ARCH or RPMTAG_OS are not legitimate packages but were still possible to install, which has been corrected (#3344).
• Packaging: Fix a regression where manual invocation of %debug_package caused problems when invoked in spec files directly (#3290).
• Packaging: Fix a regression where an empty build directory was left behind on rpmbuild -bs (#3382).
• Packaging: Fix a regression in build-id generation from compressed ELF files (#3463).
• Packaging: Fix a race condition when running multiple rpmbuild(8) instances in parallel with a non-existent %{_tmppath} (#3508).
• Packaging: Fix symlinked .la files not getting removed from the buildroot (#3304).
• Packaging: Fix brp-strip in regex-unsafe buildroots (#3492).
• Plugins: Source packages triggered plugin hooks when unpacked with rpm -i, which has been corrected (#3470).
• Plugins: Don't let the IMA plugin fail the transaction if it's running in a rootless container where IMA isn't supported (#3234).
• Plugins: Fix unshare plugin failure when installing to a chroot (#3187).
• Configuration: When editing a macro file in place, the text editor may place a backup file (e.g. with the ~ suffix) in the same directory, causing RPM to load it at startup and possibly override the original macro definitions. To help prevent that, RPM now ignores filenames with non-alphanumeric characters when looking for macro files to load (#3373).
• Documentation: Man pages have seen various formatting and punctuation fixes (#3511).
