Merge branch 'dt/name-hash-dir-entry-fix'

2015-10-29T20:59:19Z

The name-hash subsystem that is used to cope with case insensitive filesystems keeps track of directories and their on-filesystem cases for all the paths in the index by holding a pointer to a randomly chosen cache entry that is inside the directory (for its ce->ce_name component). This pointer was not updated even when the cache entry was removed from the index, leading to use after free. This was fixed by recording the path for each directory instead of borrowing cache entries and restructuring the API somewhat. * dt/name-hash-dir-entry-fix: name-hash: don't reuse cache_entry in dir_entry

Remove no-longer used #include. * tk/sigchain-unnecessary-post-tempfile: shallow: remove unused #include "sigchain.h" read-cache: remove unused #include "sigchain.h" diff: remove unused #include "sigchain.h" credential-cache--daemon: remove unused #include "sigchain.h"

read-cache: remove unused #include "sigchain.h"

After switching to use the tempfile module in commit f6ecc62d (write_shared_index(): use tempfile module), no declarations from sigchain.h are used in read-cache.c anymore. Thus, remove the #include. Signed-off-by: Tobias Klauser Signed-off-by: Junio C Hamano

name-hash: don't reuse cache_entry in dir_entry

2015-10-21T19:47:38Z

Stop reusing cache_entry in dir_entry; doing so causes a use-after-free bug. During merges, we free entries that we no longer need in the destination index. But those entries might have also been stored in the dir_entry cache, and when a later call to add_to_index found them, they would be used after being freed. To prevent this, change dir_entry to store a copy of the name instead of a pointer to a cache_entry. This entails some refactoring of code that expects the cache_entry. Keith McGuigan diagnosed this bug and wrote the initial patch, but this version does not use any of Keith's code.

Merge branch 'mh/tempfile'

2015-08-25T21:57:09Z

The "lockfile" API has been rebuilt on top of a new "tempfile" API. * mh/tempfile: credential-cache--daemon: use tempfile module credential-cache--daemon: delete socket from main() gc: use tempfile module to handle gc.pid file lock_repo_for_gc(): compute the path to "gc.pid" only once diff: use tempfile module setup_temporary_shallow(): use tempfile module write_shared_index(): use tempfile module register_tempfile(): new function to handle an existing temporary file tempfile: add several functions for creating temporary files prepare_tempfile_object(): new function, extracted from create_tempfile() tempfile: a new module for handling temporary files commit_lock_file(): use get_locked_file_path() lockfile: add accessor get_lock_file_path() lockfile: add accessors get_lock_file_fd() and get_lock_file_fp() create_bundle(): duplicate file descriptor to avoid closing it twice lockfile: move documentation to lockfile.h and lockfile.c

Hotfix for the 'untracked-cache' topic that is already in 'master'. * nd/untracked-cache: read-cache: fix untracked cache invalidation when split-index is used

Merge branch 'jk/diagnose-config-mmap-failure'

2015-06-11T16:29:55Z

The configuration reader/writer uses mmap(2) interface to access the files; when we find a directory, it barfed with "Out of memory?". * jk/diagnose-config-mmap-failure: xmmap(): drop "Out of memory?" config.c: rewrite ENODEV into EISDIR when mmap fails config.c: avoid xmmap error messages config.c: fix mmap leak when writing config read-cache.c: drop PROT_WRITE from mmap of index
