2019-03-19build: check for gpgme with pkg-config before gpgme-configEli Schwartz1-2/+2
gpgme in git master now supports pkg-config and with the next release we can and should prefer its use. However, retain the legacy code that enables building with older versions of gpgme, as a fallback.

2019-03-19Reformatting log timestamp to include time-zoneFlorian Wehner1-3/+5
The time logged is currently given as localtime without any timezone information. This is confusing in various scenarios. Examples: * If one is travelling across time-zones and the timestamps in the log appear out of order. * Comparing dates with `datediff` gives an offset by the time-zone This patch would reformat the time-stamp to a full ISO-8601 version. It includes the 'T' separating date and time including seconds.

2019-03-01Sanitize file name received from Content-Disposition headerAndrew Gregory1-1/+2
When installing a remote package with "pacman -U <url>", pacman renames the downloaded package file to match the name given in the Content-Disposition header. However, pacman does not sanitize this name, which may contain slashes, before calling rename(). A malicious server (or a network MitM if downloading over HTTP) can send a content-disposition header to make pacman place the file anywhere in the filesystem, potentially leading to arbitrary root code execution. Notably, this bypasses pacman's package signature checking. For example, a malicious package-hosting server (or a network man-in-the-middle, if downloading over HTTP) could serve the following header: Content-Disposition: filename=../../../../../../usr/share/libalpm/hooks/evil.hook and pacman would move the downloaded file to /usr/share/libalpm/hooks/evil.hook. This invocation of "pacman -U" would later fail, unable to find the downloaded package in the cache directory, but the hook file would remain in place. The commands in the malicious hook would then be run (as root) the next time any package is installed. Discovered-by: Adam Suhl <asuhl@mit.edu> Signed-off-by: Allan McRae <allan@archlinux.org>
2019-02-07libalpm: prevent 301 redirect loop from hanging the processMark Ulrich1-0/+1
If a mirror responds with a 301 redirect to itself, it will create an infinite redirect loop. This will cause pacman to hang, unresponsive to even a SIGINT. The result is pacman being unable to sync or download any package from a particular repo if its current mirror is stuck in a redirect loop. Setting libcurl's MAXREDIRS option effectively prevents a redirect loop from hanging the process.

2019-01-10libalpm/sync.c: change alpm_sync_newversion() to alpm_sync_get_new_version()Allan McRae2-6/+2
The behaviour of "pacman -Qu" was very strange... It would only consider packages from repos with Usage = Search (or All), and ignore those with Usage = Sync, Install or Upgrade. This is because the function alpm_sync_newversion() used ALPM_DB_USAGE_SEARCH for its filtering. Given this function is documented (at least in the source) to "Check for new version of pkg in sync repos", I would expect that to look at all repos. However, just changing this parameter, would result in a fairly silent change in behaviour of this function. Instead, rename the function and remove this filtering altogether. Users of this function can filter the dbs passed to this function to achieve their desired output. Signed-off-by: Allan McRae <allan@archlinux.org>

Commit 0994893b0e6b627d45a63884ac01af7d0967eff2 added the alpm_pkg_get_{make,check}depends functions but forgot to include logic for parsing these fields from the database.

2019-01-04Move skipping of duplicate sync/remove targets into libalpmMichael Straube2-2/+9
sync: As pointed out by Andrew Gregory there could be an error when adding duplicates if they are two separate packages with the same name. Add a check in alpm_add_pkg() to test whether the duplicate is actually the same package, and if so, log a debug message and return success to skip the package. If the duplicate is a different package return ALPM_ERR_TRANS_DUP_TARGET and treat that error just like any other error in pacman. remove: Change alpm_remove_pkg() to just log a debug message and return success to skip duplicates. Remove the handling of ALPM_ERR_TRANS_DUP_TARGET in pacman. Also fixes FS#49377.

Commit 2ee7a8d89ad693617307260604e1d58757fd2978 replaced a manual check for a local package with a check for the "oldpkg" member, which gets set at the beginning of the transaction. If the package was also in the remove list, such as when a package gets replaced, it would no longer be in the local db and pacman would try to remove it twice, resulting in superfluous error messages.

2018-11-02Add meson.build files to build with mesonDave Reisner2-0/+48
Provide both build systems in parallel for now, to ensure that we work out all the differences between the two. Some time from now, we'll give up on autotools. Meson tends to be faster and probably easier to read/maintain. On my machine, the full meson configure+build+install takes a little under half as long as a similar autotools-based invocation. Building with meson is a two step process. First, configure the build: meson build Then, compile the project: ninja -C build There's some mild differences in functionality between meson and autotools. specifically: 1) No singular update-po target. meson only generates individual update-po targets for each textdomain (of which we have 3). To make this easier, there's a build-aux/update-po script which finds all update-po targets and runs them. 2) No 'make dist' equivalent. Just run 'git archive' to generate a suitable tarball for distribution.
2018-10-21handle EINTR while polling scripts/hooksAndrew Gregory1-1/+9
If poll() is interrupted by a signal, alpm was closing the socket it uses for listening to script/hook output. This would drop script output at the least and kill the script at the worst.

2018-10-18alpm: Fix SIGINT handling re: aborting downloadOlivier Brunel1-0/+1
Upon receiving SIGINT a flag is set to abort the (curl) download. However, since it was never reset/initialized, if a front-end doesn't actually exit on SIGINT, and later tries any operation that needs to perform a new download, said download would always get aborted right away due to the flag not having been reset.
2018-10-18alpm: Do not raise SIGINT when filesize goes over limitOlivier Brunel1-1/+1

Many of these are pointless (e.g. there is no need to explicitly turn on spellchecking and language dictionaries for the manpages by default). The only useful modelines are the ones enforcing the project coding standards for indentation style (and "maybe" filetype/syntax, but everything except the asciidoc manpages and makepkg.conf is already autodetected), and indent style can be applied more easily with .editorconfig Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>

RFC 4880 defines two packet formats for OpenPGP. Pacman aborted its key in keyring check with an error message if it encountered the new format.

2018-01-06dload: ensure callback is always initialized onceAndrew Gregory2-4/+6
Frontends rely on an initialization call for setup between downloads. Checking for intialization after checking for a completed download can skip initialization in cases where files are small enough to be downloaded all at once (FS#56408). Relying on previous download size can result in multiple initializations if there are multiple non-transfer events prior to the download starting (fS#56468). Introduce a new cb_initialized variable to the payload struct and use it to ensure that the callback is initialized exactly once prior to any actual events.
