2021-01-09get_file_pkg_ops: update commentAllan McRae
2021-01-09libalpm: introduce get_sync_pkg_ops() helperEmil Velikov
Currently default_pkg_ops is accessed in two different ways. There is get_file_pkg_ops (in be_package.c) creating a local once-off 'tweaked' copy. As well as load_pkg_for_entry (be_sync.c) which modifies in-place and uses default_pkg_ops. This seems rather misleading and fragile approach. Introduce a helper for the second use-case so that default_pkg_ops is handled consistently and essentially remains unchanged throughout.

2021-01-09Remove unused SYMHIDDEN macrosEmil Velikov
The macro hasn't been used since 2007 with commit 7f7da2b5fc01f46d28236384540c7ecfdac16a63. Although it was still copied over into alpm_list.c an year or so later with commit ca1a1871 ("More cleanup to alpm_list") Just remove all instances of it.

2020-09-03remove more autotools filesEli Schwartz
We forgot to remove m4/ in commit 454ea024383eab60295e4c4fdf2c329475887b2c and now it's tragically reminding me of autotools! Also take this opportunity to drop some symlinks in lib/libalpm/ for libcommon source files. In autotools these were built specifically for libalpm and needed to be available in that directory, but the meson setup just has libalpm depend on libcommon. So these pseudo source files aren't needed anymore. Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>
2020-08-10Enable sha256/md5 hash verification if detached signatures are usedAnatol Pomozov
Pacman has multiple ways to verify package content integrity: - gpg signature - sha256 - md5 These verification mechanisms overlap each other. gpg signatures already contain hash value of the package content. So if a package signature is present then pacman ignored the other 2 hash values. This worked well with signtures embedded into pacman database. Recently pacman got an ability to handle detached signatures (*.sig files located next to the package files). If pacman verifies detached signature only then one can replace pkg+sig files with some other content and pacman still processes it as a valid package. To prevent it we need to verify database<->package integrity using hash values stored in the database. This commit fixes FS#67232 The new debug output is: checking package integrity... debug: found cached pkg: /var/cache/pacman/pkg/ruby-2.7.1-2-x86_64.pkg.tar.zst debug: sha256sum: 77baf61c62c5570b3a37cf0c3b16c5d9a97dde6fedd1a3528bf0cc5f96dd5e52 debug: checking sha256sum for /var/cache/pacman/pkg/ruby-2.7.1-2-x86_64.pkg.tar.zst debug: sig data: <from .sig> debug: checking signature for /var/cache/pacman/pkg/ruby-2.7.1-2-x86_64.pkg.tar.zst debug: 1 signatures returned debug: fingerprint: B5971F2C5C10A9A08C60030F786C63F330D7CB92 Signed-off-by: Anatol Pomozov <anatol.pomozov@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2020-08-10Fix error during keyring checkingAnatol Pomozov
With current master version the 'keyring checking' step produces an error: debug: returning error 6 from alpm_pkg_get_sig (../lib/libalpm/package.c: 274) : wrong or NULL argument passed The package signature is still checked later at the integrity verification step though.

2020-07-14Build signature remote name based on the main payload nameAnatol Pomozov
The main payload final name might be affected by url redirects or Content-Disposition HTTP header value. We want to make sure that accompanion *.sig filename always matches the package filename. So ignore finalname/Content-Disposition for the *.sig file. It also helps to fix a corner case when the download URL does not contain a filename and server provides Content-Disposition for the main payload but not for the signature payload.

2020-07-07Fallback to detached signatures during keyring checkAnatol Pomozov
Pacman has a 'key in keyring' verification step that makes sure the signatures have a valid keyid. Currently pacman parses embedded package signatures only. Add a fallback to detached signatures. If embedded signature is missing then it tries to read corresponding *.sig file and get keyid from there.

2020-07-07Move signature payload creation to download engineAnatol Pomozov
Until now callee of ALPM download functionality has been in charge of payload creation both for the main file (e.g. *.pkg) and for the accompanied *.sig file. One advantage of such solution is that all payloads are independent and can be fetched in parallel thus exploiting the maximum level of download parallelism. To build *.sig file url we've been using a simple string concatenation: $requested_url + ".sig". Unfortunately there are cases when it does not work. For example an archlinux.org "Download From Mirror" link looks like this https://www.archlinux.org/packages/core/x86_64/bash/download/ and it gets redirected to some mirror. But if we append ".sig" to the end of the link url and try to download it then archlinux.org returns 404 error. To overcome this issue we need to follow redirects for the main payload first, find the final url and only then append '.sig' suffix. This implies 2 things: - the signature payload initialization need to be moved to dload.c as it is the place where we have access to the resolved url - *.sig is downloaded serially with the main payload and this reduces level of parallelism Move *.sig payload creation to dload.c. Once the main payload is fetched successfully we check if the callee asked to download the accompanied signature. If yes - create a new payload and add it to mcurl. *.sig payload does not use server list of the main payload and thus does not support mirror failover. *.sig file comes from the same server as the main payload. Refactor event loop in curl_multi_download_internal() a bit. Instead of relying on curl_multi_check_finished_download() to return number of new payloads we simply rerun the loop iteration one more time to check if there are any active downloads left.

2020-06-26Cleanup the old sequential download codeAnatol Pomozov

2020-06-26Convert '-U pkg1 pkg2' codepath to parallel downloadAnatol Pomozov
Installing remote packages using its URL is an interesting case for ALPM API. Unlike package sync ('pacman -S pkg1 pkg2') '-U' does not deal with server mirror list. Thus _alpm_multi_download() should be able to handle file download for payloads that either have 'fileurl' field or pair of fields ('servers' and 'filepath') set. Signature for alpm_fetch_pkgurl() has changed and it accepts an output list that is populated with filepaths to fetched packages. Signed-off-by: Anatol Pomozov <anatol.pomozov@gmail.com>
2020-06-11build: add libintl dependency to meson and the .pc fileEli Schwartz
In order to use gettext on systems where it is not part of libc, the correct linker flags are needed in libalpm.pc (for static compilation). This has never been the case. The new meson build system currently only checks for ngettext in libc, but does not fall back to searching for the existence of -lintl; add it to the libalpm dependencies.
