2019-10-12run XferCommand via execAndrew Gregory4-19/+117
system() runs the provided command via a shell, which is subject to command injection. Even though pacman already provides a mechanism to sign and verify the databases containing the urls, certain distributions have yet to get their act together and start signing databases, leaving them vulnerable to MITM attacks. Replacing the system call with an almost equivalent exec call removes the possibility of a shell-injection attack for those users. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>

2019-10-09makepkg: do not save fflags when creating packagesEli Schwartz1-2/+2
Saving fflages breaks reproducible builds due to encoding information specific to the filesystem that was used to build the package. This information is not needed for packaging purposes anyway. Including fflags also means that attempting to extract a package file as root (or fakeroot) might result in angry warnings being printed to the console by bsdtar, followed by a non-zero exit code, unless the user remembers to use --no-fflags during extraction. This is unpleasant UI, even if pacman itself won't care about these. Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>

2019-10-07pacman-key: receive keys from WKD with -r/--recv-keysJonas Witschel1-8/+17
If an email address is specified, we use --locate-key to look up the key using WKD and keyserver as a fallback. If the key is specified as a key ID, this doesn't work, so we use the normal keyserver-based --recv-keys. Note that --refresh-keys still uses the keyservers exclusively for refreshing, though the situation might potentially be improved in a new version of GnuPG: https://lists.gnupg.org/pipermail/gnupg-users/2019-July/062169.html Signed-off-by: Jonas Witschel <diabonas@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>

2019-10-07makepkg: propagate E_REMOVE_BUILD_DEPSAlad Wenter1-1/+5
remove_deps is called once, at the end of clean_up() before makepkg exit. If remove_deps returns >0 (e.g. when pressing "n" in the resulting prompt), the error is caught by the ERR signal handler. This in turns sends SIGUSR1 to the process group, with resulting exit code 138. In case remove_deps fails, this patch exits makepkg with E_REMOVE_DEPS if there was no previous error (that is, EXIT_CODE equals E_OK). Otherwise, makepkg exits with EXIT_CODE.

2019-10-07makepkg: remove makedepends before installing built packageErich Eckner1-0/+3
When running `makepkg -i` it may be necessary to first remove make- and checkdepends before installing the built package - for example if they conflict each other.

2019-10-07makepkg: Delete logpipe when exitingAustin Lund1-3/+4
The logpipe fifo can remain when exiting on a non-error condition such as recieving signals INT and USR1. This can be seen by doing either a manual CTRL-C to interrupt the build or by sending a signal such as: $ makepkg & sleep 5 ; kill -USR1 $!

2019-10-07meson: work around broken pkg-config file with private requiresEli Schwartz1-12/+10
In addition to the general issue of staticlibs linkage, linking a static lib to a library() does not seem to generate the needed Libs.private. Rework how we handle this entirely. Instead of relying on convenience libraries, we will *sigh* go extract a boatload of .o files again, then relink those to the installable libalpm, while mentioning our dependencies again. We still have our guaranteed static library for linking arbitrary programs with (e.g. vercmp), and we still only generate one identical copy of the .o files, but now we potentially `ar` it up twice, which isn't so bad. And linking still works, and pkg-config files also still work. One alternative would be to explicitly list our dependencies to pkgconfig.generate with requires_private, but since gpgme might be an elevated config-tool dependency, this can fail with: meson.build:341:10: ERROR: requires argument not a string, library with pkgconfig-generated file or pkgconfig-dependency object, got <GpgmeDependency gpgme: True> Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>
2019-10-07meson: fix incorrect libalpm versionEli Schwartz1-1/+1
LIB_VERSION is supposed to be something like 11.0.1, not simply reiterate the project version. As a result, we ended up with this: $ pacman -V [...] Pacman v5.1.0 - libalpm v5.1.0 [...] Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>
2019-10-07meson: fix libcommon being publicly exposed as a static link dependencyEli Schwartz1-2/+2
libcommon isn't even installed, so that means libalpm.a (if installed) is fatally broken as it misses objects. The problem is that meson doesn't handle this case correctly: https://github.com/mesonbuild/meson/issues/3934 https://github.com/mesonbuild/meson/issues/3937 https://github.com/mesonbuild/meson/pull/3939 Work around this by manually extracting libcommon's .o files into the list of objects used to create libalpm.

2019-10-07Support file with seccomp enabledEli Schwartz7-1/+36
Not all compression types can be detected in the seccomp sandbox, so we need to disable it. This requires either configuring makepkg to know the sandbox is available, or checking for file >= 5.38 in which the sandbox option is a no-op even when seccomp is disabled. - Requires autoconf-archive for autotools version compare macro. - meson version comparison could be made a lot simpler using meson-git.

2019-10-07pacman-key: clean keys on import to remove unknown signaturesEli Schwartz1-0/+1
There is no good reason to bloat the keyring by importing tons of signatures we cannot use; drop any signatures that don't validate against another available key (probably the master keys). If any desired signatures get cleaned, the key can be refreshed after importing the new signing public key.

2019-10-07pacman-key: make sure we actually use the Web of Trust, which GnuPG doesn't.Eli Schwartz1-0/+5
By default, the latest versions of GnuPG disable the Web of Trust and refuse to import signatures from public keyservers. This is to prevent denial of service attacks, because refusing to import signatures only if the key size is too big, is apparently too silly to consider. Either way, pacman needs the WoT. If pacman imports a key at all, it means everything failed and we are in fallback mode, trying to overcome a shortcoming in the availability of keys in the keyring package. (This commonly means the user needs to acquire a new key during the same transaction that updates archlinux-keyring.) In order for that new key to be usable, it *must* also import signatures from the Master Keys. I don't give credence to this supposed DoS, since the worst case scenario is nothing happening and needing to CTRL+C in order to exit the program. In the case of pacman, this is better than being unable to install anything at all (which is gnupg doing a much more harmful DoS to pacman), and in the already unusual case where something like --refresh-keys is being used directly instead of depending on the keyring package itself, gnupg supports WKD out of the box and will prefer that for people whose keys are marketed as being non-DOSable.

2019-10-07pacman-key: when refreshing gpg.conf, don't truncate option checkingEli Schwartz1-1/+1
If an option is a two-part option, we print both (separated by IFS=' '), but when grepping to see if it already exists, we only checked the first component. This means that something like keyserver-options could only check if there were existing keyserver options of any sort, but not which ones.

2019-10-07signing: add ability to import keys using a WKDJonas Witschel1-13/+84
Currently pacman relies on the SKS keyserver network to fetch unknown PGP keys. These keyservers are vulnerable to signature spamming attacks, potentionally making it impossible to import the required keys. An alternative to keyservers is a so-called Web Key Directory (WKD), a well-known, trusted location on a server from where the keys can be fetched. This commit adds the ability to retrieve keys from a WKD. Due to the mentioned vulnerabilities, the WKD is tried first, falling back to the keyservers only if no appropriate key is found there. In contrast to keyservers, keys in a WKD are not looked up using their fingerprint, but by email address. Since the email address of the signing key is usually not included in the signature, we will use the packager email address to perform the lookup. Also see FS#63171.

2019-10-07signing: move key import confirmation before key_searchJonas Witschel5-39/+60
Ask the user whether they want to import a missing key before even doing a search on the keyserver. This will be useful for getting Web Key Directory support in place: for a WKD, looking up and importing a key are a single action, so the current key_search -> QUESTION -> key_import workflow does not apply. Since only the ID of the package signing key is available before key_search, we display the packager variable in addition to the key ID for user convenience.

2019-10-07dload: never return NULL from get_filenameDave Reisner1-2/+4
Downloads with a Content-Disposition header will typically not include slashes. When they do, we should most certainly only take the basename, but when they don't, we should treat the header value as the filename. Crash introduced in d197d8ab82cf when we started using get_filename in order to rightfully avoid an arbitrary file overwrite vulnerability. Signed-off-by: Allan McRae <allan@archlinux.org>

2019-10-04autotools: distribute meson filesEli Schwartz10-2/+22
If we use make dist to create the official, signed release tarballs, those will not have meson build files by default since autotools doesn't know what they are. Also distribute all src/common/ files. We never strictly needed any of them to be distributed with autotools, because the dist tarball dereferences the symlinks (???), but only some of them were being distributed, and meson needs them to be in the right location as we only build libcommon from the primary files.
