* 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.

* 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

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.

Note that you'll need to strip the newline from the file (-> len-17). If HEAD is a symbolic link pointing directly to a branch below refs/heads/, do a readlink() instead to find the ref name.
