* gerrit: some fixes for the rfc scriptCsaba Henk2011-07-231-2/+2
| | | | | | | | | | | | | | | | | | | | | In rebase_changes(): - Using "--all" for git fetch is bogus: the scope of this quantification is not over the tracked refs of the upsteam repo (which we do want, but that kind of universal quantification is already implied by the notion of "tracking"), but over the set of all the registered remotes, which is an annoying side effect. - $EDITOR is weaker than the git configuration settings. For the purpose of the script, we need to override any kind of setting, and that can be done via $GIT_EDITOR. Cf. git-fetch(1), git-commit(1).

* posix: perform readdir filling in locked regionAnand Avati2011-07-161-77/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When two application threads share an open dir fd (DIR *) and issue readdirs, storage/posix will receive separate readdir fops in separate threads in parallel. This has two-fold issues 1. In the following pair of operations - entry = readdir(dir) and strcpy (gf_dirent->name, entry->d_name) @entry is a static buffer in libc which can get reused by another thread to get filled with a longer name. This can cause the second operation to overflow the buffer as the allocation was for the smaller name. 2. In the following pair of operations - seekdir (dir, offset) and entry = readdir(dir) If two threads are executing these sequence in parallel in separate threads, then one of them will end up reading wrong/unexpected entries. It would be sufficient to fix 1. by using readdir_r but that still keeps the second race open. Hence the patch moves all the set of operations to a locked region which solves both races.
