* ui-plain.c: Do not access match variable in print_*()Lukas Fleischer2013-03-04
| | | | | | | | | Move all code setting the match variable to walk_tree(). This allows for easily moving this variable into a context structure without having to pass the context to print_*(). Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* ui-blob.c: Use a context structure in walk_tree()Lukas Fleischer2013-03-04
| | | | | | | | | | | | Do not misuse global variables to save the context. Instead, use the context pointer which was designed to share information between a read_tree_fn and the caller. This also prevents from potential misuse of the global pointers match_path and matched_sha1 after the referenced values have been overwritten on the stack.

* ui-snapshot.c: Fill argv[0] with dummy.Jason A. Donenfeld2013-03-04
| | | | | | | | | parse_archive_args does not pass PARSE_OPT_KEEP_ARGV0 to parse_args, which means the first argument will be discarded, as though it were a function being called from the command-line. Thus, we fill argv[0] with a dummy argument to prevent this from happening. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

* Support unannotated tags in git-clone.Jason A. Donenfeld2013-02-01
| | | | | | | | | | | | | | | | | | | Matthew McClintock reported that older unannotated tags were not correctly being cloned and did not appear in info/refs. Further investigation revealed some dubious prefix comparison code for determining whether or not to write refs in info/refs. After comparing it with git's own http-backend.c, it appears upstream does not use this prefix logic. OTOH, I don't know what the reasoning was when the prefix logic was introduced. It appears to me to just be buggy, though it's possible there are other reasons, and we'll have to revisit this commit. But for now, Works For Me. Signed-off-by: Jason A.

* Format git diff headers correctly when adding or removing files.Michael Halstead2012-11-15
| | | | | | Copying the output of cgit and using it in patches now works when adding files to or removing files from the repository. This is helpful for people who use cgit in their patch workflow.

* syntax-highlighting.sh: Fix command injection.Jason A. Donenfeld2012-10-27
| | | | | | | | | By not quoting the argument, an attacker with the ability to add files to the repository could pass arbitrary arguments to the highlight command, in particular, the --plug-in argument which can lead to arbitrary command execution. This patch adds simple argument quoting.

* ui-log: Add "commit-sort" option for controlling commit orderingTobias Bieniek2012-10-17
| | | | | | | This makes it possible to use strict commit date ordering or strict topological ordering by passing the corresponding flags to "git log". Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
* ui-repolist: Add "section-sort" flag to control section sorting.Tobias Bieniek2012-10-17
| | | | | | | | Flag which, when set to "1", will sort the sections on the repository listing by name. Set this flag to "0" if the order in the cgitrc file should be preserved. Default value: "1". Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
* scan-tree: Unify gitweb.* and cgit.* settings into one config option.Jason A. Donenfeld2012-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | After some back and forth with Jamie and René, it looks like the git config semantics are going to be like this: - gitweb.category maps to the cgit repo config key "section" - gitweb.description maps to the cgit repo config key "desc" - gitweb.owner maps to the cgit repo config key "owner" - cgit.* maps to all cgit repo config keys This option can be enabled with "enable-git-config=1", and replaces all previous "enable-gitweb-*" config keys. The order of operations is as follows: - git config settings are applied in the order that they exist in the git config file - if the owner is not set from git config, get the owner using the usual getpwuid call - if the description is not set from git config, look inside the static $path/description file - if section-from-path=1, override whatever previous settings were inside of git config using the section-from-path logic - parse $path/cgitrc for local repo.* settings, that override all previous settings

| | | | | | | | | | | | This makes it possible to activate the enable_commit_graph, enable_log_filecount, and enable_log_linecount for individual repositories, even if the global setting is "0" (default). The commit that introduced the broken behavior was e189344, and the commit message of that makes it clear that this wasn't the intended behavior. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

And here's the reproducer: It was tricky to reproduce, because git prohibits use of an empty "name" in a commit ID. To construct the offending commit, I had to resort to using "git hash-object". git init -q foo && ( cd foo && echo a > j && git add . && git ci -q --author='au <T at h.or>' -m. . && h=$(git cat-file commit HEAD|sed 's/au //' \ |git hash-object -t commit -w --stdin) && git co -q -b test $h && git br -q -D master && git br -q -m test master) git clone -q --bare foo foo.git cat <<EOF > in repo.url=foo.git repo.path=foo.git EOF CGIT_CONFIG=in QUERY_STRING=url=foo.git valgrind ./cgit The valgrind output is what you see above. AFAICS, this is not exploitable thanks (ironically) to the use of strncpy. Since that -1 translates to SIZE_MAX and this is strncpy, not only does it copy whatever is in "head" (up to first NUL), but it also writes SIZE_MAX - strlen(head) NUL bytes into the destination buffer, and that latter is guaranteed to evoke a segfault. Since cgit is single-threaded, AFAICS, there is no way that the buffer clobbering can be turned into an exploit.
* ui-snapshot: pass -n to gzip, to suppress timestampJason A. Donenfeld2012-09-27
| | | | | | | | | | Since cgit snapshots of tags are often used for releases, we don't want the rarely used feature of the gzip compressor that includes an embedded timestamp into the archive, since this makes each tarball of the same (potentially signed) tag different. This commit refactors the archive handling code a bit so that each different format is able to run with an arbitrary argv for the filter.
