2015-07-20ensure matching database and package versionLevente Polyak1-0/+18
While loading each package ensure that the internal version matches the expected database version to avoid the possibility to circumvent the version check. This issue can be used by an attacker to trick the software into installing an older version. The behavior can be exploited by a man-in-the-middle attack through specially crafted database tarball containing a higher version, yet actually delivering an older and vulnerable version, which was previously shipped.

2015-07-15Read file lists from databasesAllan McRae1-2/+36
If a sync database contains a "files" file, the file list will be read. Currently, there is no known demand for the file list to be lazy loaded by any libalpm frontend, so these files are read whenever present. Lazy loading can be implemented when a demand exists. Signed-off-by: Allan McRae <allan@archlinux.org>
2015-07-15Allow frontends to specify the sync database extensionAllan McRae6-8/+44
This allows frontends to select between the .db and .files databases currently supplied by repo-add or any other compatible database. Signed-off-by: Allan McRae <allan@archlinux.org>
2015-07-14Do not warn about packages that optionally require a removal when ignoring depsAllan McRae1-1/+3
If a transaction is removing a package while ignoring all dependencies, there should not be any warning about other packages optionally requiring it. Signed-off-by: Allan McRae <allan@archlinux.org>

2015-05-12libalpm: Do a sanity check before manipulating final DB URLDavid Macek1-4/+11
The change in commit 9d96bed9d6b57 causes download errors for the .db.sig file in case the final URL for the .db file contains query strings or other unexpected stuff. This commit isn't intended to be a total solution, but it should eliminate the problem in the most obvious cases. Signed-off-by: Allan McRae <allan@archlinux.org>
2015-05-12Fix comment in alpm_db_updateDavid Macek1-1/+1
Fix comment to better explain the magic constant used when allocating a buffer for ".db.sig" URL. Signed-off-by: Allan McRae <allan@archlinux.org>
2015-05-12alpm_logaction: implement documented return valueAndrew Gregory1-8/+16
"return 0 on success, -1 on error (pm_errno is set accordingly)" Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2015-05-12alpm_logaction: allow falling back to syslogAndrew Gregory1-1/+1
Even if opening the log file fails, if a user has enabled syslog we may still be able to log to that. Set the error return value and continue instead of bailing out. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2015-05-12alpm_logaction: check logfile before openingAndrew Gregory1-1/+1
valgrind does not like calling open(NULL, ...). This also makes the return value 0 if logfile has not been set. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2015-03-26close stdin before running install scriptsAndrew Gregory1-0/+1
libalpm does not guarantee that script output will be presented to the user or that stdin will be connected to a terminal. Close stdin so that scripts do not attempt to use it for user interaction.

2015-03-26be_package: fallback to standard filelist loadingAndrew Gregory1-15/+22
In order to work properly, loading the filelist from an mtree file requires a libarchive patch that has not yet been included in an official release.[1] Under certain circumstances, an unpatched libarchive may refuse to read the mtree file due to inconsistencies between it and the user's file system. In order to allow alpm to recover in this situation, read the mtree data into a temporary filelist that is only copied over to the package if the entire read is successful.

2015-03-03remove: use strcmp for files in skip_removeAndrew Gregory1-49/+33
Paths from noupgrade, the transaction skip_remove, and package backup lists were combined into a single list matched using fnmatch causing paths with glob characters to match unrelated files. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2015-02-01trans_commit: restore pm_errno after updating logAndrew Gregory1-0/+4
If the call to alpm_logaction failed it would overwrite pm_errno, leading to error messages unrelated to the actual reason the transaction failed. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2015-01-21extract_single_file: consolidate extraction logicAndrew Gregory1-79/+61

2015-01-21extract_single_file: use .pacnew for check filesAndrew Gregory1-27/+13
Prevents the need to rename the file if we end up keeping it and ensures that pacnew files always reflect the most recent version by overwriting stale copies. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>
2015-01-21remove support for .pacorig filesAndrew Gregory2-73/+24
Leave user files in place and save new config files with a .pacnew extension. This reduces the complexity of file extraction and respects the principle that pacman shouldn't modify files it didn't create. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>
2015-01-21extract_single_file: use full path in messagesAndrew Gregory1-18/+13
If an error occurs the actual path being extracted is more useful than the original path from the package file list. The original path is still used for checks that use it directly. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>
2015-01-21extract_single_file: factor out db file extractionAndrew Gregory1-28/+32
alpm's database files (.INSTALL, .MTREE, etc.) should be extracted no matter what; skip mtree/needbackup/noextract/noupgrade checks for them. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>

2015-01-21conf.c: use masks for siglevel inheritanceAndrew Gregory2-4/+1

2015-01-21fix geometric growth in _alpm_greedy_growDaniel Micay1-1/+1
It was allocating the required size rather than the calculated new size, resulting in pathological incremental reallocations. Signed-off-by: Daniel Micay <danielmicay@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2015-01-21be_local: fix _alpm_greedy_grow usageDaniel Micay1-1/+1
The files_size variable contains the current capacity (in bytes) and should not be used to calculate the next length increment. It only works because _alpm_greedy_grow currently results in incremental growth. Signed-off-by: Daniel Micay <danielmicay@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2015-01-02initialize pointers passed to _alpm_pkg_dupAndrew Gregory2-2/+2
_alpm_pkg_dup leaves the destination pointer unaltered in case of fatal errors, so when commits 2f0ca00e and be4198b3 freed the pointer, they fixed a memory leak on non-fatal errors by replacing it with a segmentation fault on fatal errors.
