2018-08-07sequencer: fix quoting in write_author_scriptLibravatar Phillip Wood2-10/+44
Single quotes should be escaped as \' not \\'. The bad quoting breaks the interactive version of 'rebase --root' (which is used when there is no '--onto' even if the user does not specify --interactive) for authors that contain "'" as sq_dequote() called by read_author_ident() errors out on the bad quoting. For other interactive rebases this only affects external scripts that read the author script and users whose git is upgraded from the shell version of rebase -i while rebase was stopped when the author contains "'". This is because the parsing in read_env_script() expected the broken quoting. This patch includes code to handle the broken quoting when git has been upgraded while rebase was stopped. It does this by detecting the missing "'" at the end of the GIT_AUTHOR_DATE line to see if it should dequote \\' as "'". Note this is only implemented for normal picks, not for creating a new root commit (rebase will stop with an error complaining out bad quoting in that case). The fallback code has been manually tested by reverting both the quoting fixes in write_author_script() and the previous fix for the missing "'" at the end of the GIT_AUTHOR_DATE line and running t3404-rebase-interactive.sh. Ideally rebase and am would share the same code for reading and writing the author script, but this commit just fixes the immediate bug.

2018-08-07sequencer: handle errors from read_author_ident()Libravatar Phillip Wood1-2/+9
Check for a NULL return value from read_author_ident() that indicates an error. Previously the NULL author was passed to commit_tree() which would then fallback to using the default author when creating the new commit. This changed the date and potentially the author of the commit which corrupted the author data compared to its expected value.

2018-07-31sequencer: don't die() on bogus user-edited timestampLibravatar Eric Sunshine1-0/+9
read_author_ident() is careful to handle errors "gently" when parsing "rebase-merge/author-script" by printing a suitable warning and returning NULL; it never die()'s. One possible reason that parsing might fail is that "rebase-merge/author-script" has been hand-edited in such a way which corrupts it or the information it contains. However, read_author_ident() invokes fmt_ident() which is not so careful about failing "gently". It will die() if it encounters a malformed timestamp. Since read_author_ident() doesn't want to die() and since it's dealing with possibly hand-edited data, take care to avoid passing a bogus timestamp to fmt_ident(). A more "correctly engineered" fix would be to add a "gentle" version of fmt_ident(), however, such a change it outside the scope of the bug-fix series. If fmt_ident() ever does grow a "gentle" cousin, then the manual timestamp check added here can be retired.

2018-07-31sequencer: fix "rebase -i --root" corrupting author header timestampLibravatar Eric Sunshine2-15/+10
When "git rebase -i --root" creates a new root commit, it corrupts the "author" header's timestamp by prepending a "@": author A U Thor <author@example.com> @1112912773 -0700 The commit parser is very strict about the format of the "author" header, and does not allow a "@" in that position. The "@" comes from GIT_AUTHOR_DATE in "rebase-merge/author-script", signifying a Unix epoch-based timestamp, however, read_author_ident() incorrectly allows it to slip into the commit's "author" header, thus corrupting it. One possible fix would be simply to filter out the "@" when constructing the "author" header timestamp, however, a more correct fix is to parse the GIT_AUTHOR_DATE date (via parse_date()) and format the parsed result into the "author" header. Since "rebase-merge/author-script" may be edited by the user, this approach has the extra benefit of catching other potential timestamp corruption due to hand-editing. We can do better than calling parse_date() ourselves and constructing the "author" header manually, however, by instead taking advantage of fmt_ident() which does this work for us. The benefits of using fmt_ident() are twofold. First, it simplifies the logic considerably by allowing us to avoid the complexity of building the "author" header in parallel with and in the same buffer from which "rebase-merge/author-script" is being parsed. Instead, fmt_ident() is invoked to compose the header after parsing is complete. Second, fmt_ident() is careful to prevent "crud" from polluting the composed ident. As with validating GIT_AUTHOR_DATE, this "crud" avoidance prevents other (possibly hand-edited) bogus author information from "rebase-merge/author-script" from corrupting the commit object.

2018-07-31sequencer: fix "rebase -i --root" corrupting author header timezoneLibravatar Eric Sunshine2-2/+7
When "git rebase -i --root" creates a new root commit, it corrupts the "author" header's timezone by repeating the last digit: author A U Thor <author@example.com> @1112912773 -07000 This is due to two bugs. First, write_author_script() neglects to add the closing quote to the value of GIT_AUTHOR_DATE when generating "rebase-merge/author-script". Second, although sq_dequote() correctly diagnoses the missing closing quote, read_author_ident() ignores sq_dequote()'s return value and blindly uses the result of the aborted dequote. sq_dequote() performs dequoting in-place by removing quoting and shifting content downward. When it detects misquoting (lack of closing quote, in this case), it gives up and returns an error without inserting a NUL-terminator at the end of the shifted content, which explains the duplicated last digit in the timezone. (Note that the "@" preceding the timestamp is a separate bug which will be fixed subsequently.)

2018-07-31sequencer: fix "rebase -i --root" corrupting author headerLibravatar Eric Sunshine2-2/+10
When "git rebase -i --root" creates a new root commit (say, by swapping in a different commit for the root), it corrupts the commit's "author" header with trailing garbage: author A U Thor <author@example.com> @1112912773 -07000or@example.com This is a result of read_author_ident() neglecting to NUL-terminate the buffer into which it composes the "author" header. (Note that the "@" preceding the timestamp and the extra "0" in the timezone are separate bugs which will be fixed subsequently.) Security considerations: Construction of the "author" header by read_author_ident() happens in-place and in parallel with parsing the content of "rebase-merge/author-script" which occupies the same buffer. This is possible because the constructed "author" header is always smaller than the content of "rebase-merge/author-script". Despite neglecting to NUL-terminate the constructed "author" header, memory is never accessed (either by read_author_ident() or its caller) beyond the allocated buffer since a NUL-terminator is present at the end of the loaded "rebase-merge/author-script" content, and additional NUL's are inserted as part of the parsing process.

The return value of ewah_read_mmap() is now an ssize_t, since we could (in theory) process up to 32GB of data. This would never happen in practice, but a corrupt or malicious .bitmap or index file could convince us to do so. Let's make sure that we don't stuff the value into an int, which would cause us to incorrectly move our pointer forward. We'd always move too little, since negative values are used for reporting errors. So the worst case is just that we end up reporting a corrupt file, not an out-of-bounds read.

2018-06-18ewah_read_mmap: bounds-check mmap readsLibravatar Jeff King3-5/+35
The on-disk ewah format tells us how big the ewah data is, and we blindly read that much from the buffer without considering whether the mmap'd data is long enough, which can lead to out-of-bound reads. Let's make sure we have data available before reading it, both for the ewah header/footer as well as for the bit data itself. In particular: - keep our ptr/len pair in sync as we move through the buffer, and check it before each read - check the size for integer overflow (this should be impossible on 64-bit, as the size is given as a 32-bit count of 8-byte words, but is possible on a 32-bit system) - return the number of bytes read as an ssize_t instead of an int, again to prevent integer overflow - compute the return value using a pointer difference; this should yield the same result as the existing code, but makes it more obvious that we got our computations right The included test is far from comprehensive, as it just picks a static point at which to truncate the generated bitmap. But in practice this will hit in the middle of an ewah and make sure we're at least exercising this code.

Support for the --set-upstream option was removed in 52668846ea (builtin/branch: stop supporting the "--set-upstream" option, 2017-08-17). The change did not completely remove the command due to an issue noted in the commit's log message. So, a test was added to ensure that a command which uses the '--set-upstream' option fails instead of silently acting as an alias for the '--set-upstream-to' option due to option parsing features. To avoid confusion, clarify that the option is disabled intentionally in the corresponding test description. The test is expected to be around as long as we intentionally fail on seeing the '--set-upstream' option which in turn we expect to do for a period of time after which we can be sure that existing users of '--set-upstream' are aware that the option is no longer supported.
