2014-08-19Make settrans return value returned by chroot commandSvante Signell
* utils/settrans.c (main): In case of chroot_command, get status from waitpid() call, and call error() appropriately.
2014-07-17Make the ncursesw driver of the console client compile properlyMarek Benc
* console-client/Makefile (NCURSESW_SO_SRCS): Move definition to after inclusion of Makeconf.
2014-06-30libpipe: fix spurious calls to pipe_sendRichard Braun
* libpipe/pipe.c (pipe_send): Skip processing if there is nothing to send.
2014-06-28Revert "libpipe: fix calls to pipe_send with no data"Richard Braun
This reverts commit 6f856c62613ffc82bf3572a372d2851638c2fb90. As the comment right above the change says, "this [sending control packets] depends on the fact that we always write a data packet".
2014-06-28libpipe: fix calls to pipe_send with no dataRichard Braun
* libpipe/pipe.c (pipe_send): Check that there actually is any data to send before calling the pipe write operation.
2014-06-23ext2fs: use correct type for block numbersJustus Winter
* ext2fs/dir.c (count_dirents): Use block_t for nb. (diskfs_get_directs): Likewise for blkno, nblks.
2014-06-23libdiskfs: fix deadlockJustus Winter
Previously, libdiskfs would deadlock on contention on renamedirlock due to the lock being taken spuriously. Found using fsstress from the Linux Test Project. * libdiskfs/dir-rename.c (diskfs_S_dir_rename): Remove spurious pthread_mutex_lock.
2014-06-22libdiskfs: expose the ST_NOATIME flagPino Toscano
Expose ST_NOATIME as flag (if available in glibc) if diskfs is set in noatime mode. * libdiskfs/file-statfs.c (diskfs_S_file_statfs): Set ST_NOATIME if _DISKFS_NOATIME is set.
2014-06-18libdiskfs: add permission check to file_chflagsJustus Winter
Only root is allowed to change the high 16 bits. The TODO entry says otherwise, but that must be a mistake. For reference, see the glibc sources, sysdeps/mach/hurd/bits/stat.h. * libdiskfs/file-chflags.c (diskfs_S_file_chflags): Add permission check. * TODO (libdiskfs): Remove entry.
2014-06-18libports: avoid realloc(3) corner caseJustus Winter
If the size argument is 0, realloc may either return NULL, or return a pointer that is only valid for use with free(3). In either case, the memory is freed. So if realloc would return NULL (it does not on GNU), the current code would double free p. Found using the Clang Static Analyzer. * libports/bucket-iterate.c (_ports_bucket_class_iterate): Avoid calling realloc if no ports were matched.
2014-06-18trans/fakeroot: fix error handlingJustus Winter
Found using the Clang Static Analyzer. * trans/fakeroot.c (new_node): Do not leak a pointer to freed memory. Store NULL at *np instead. This fixes a node use-after-free in netfs_S_dir_lookup.
2014-06-18libshouldbeinlibc: fix dead initialization in fmt_named_intervalJustus Winter
Found using the Clang Static Analyzer. * libshouldbeinlibc/timefmt.c (fmt_named_interval): Fix dead initialization.
2014-06-18ftpfs: fix error handling in refresh_dirJustus Winter
Found using the Clang Static Analyzer. * ftpfs/dir.c (refresh_dir): Fix error handling.
2014-06-17Add mach_debug defs rulesDavid Michael
* Makeconf (mach_debug_defs_names,mach_debug_defs): New variables. * Makeconf: Add rule to generate local $(mach_debug_defs) files. * procfs/Makefile: Remove vpath for mach_debug defs.

2014-06-15utils/settrans: implement settrans --startJustus Winter
Start the translator specified by the NODE's passive translator record and set it as NODE's active translator. This is the equivalent of doing: % settrans --active /node $(showtrans /node) * utils/settrans.c (argp_option): Add --start. (parse_opt): Handle --start. (main): Retrieve the passive translator record if --start is given.

* configure.ac: Call AC_NO_EXECUTABLES when cross-compiling.
2014-05-29libdiskfs: use a hash table for the name cacheJustus Winter
Previously, name cache lookup operation completed in O(n) time. This means that making the cache too large would decrease the performance. Therefore it was required to tune the size. Implement the name cache using a hash table. We use buckets of a fixed size. We approximate the least-frequently used cache algorithm by counting the number of lookups using saturating arithmetic in the two lowest bits of the pointer to the name. Using this strategy we achieve a constant worst-case lookup and insertion time. Since we are not bound by the size of the cache anymore, increase its size from 200 to 1024. * libdiskfs/name-cache.c: Implement the name cache using a hash table. (diskfs_enter_lookup_cache): Change accordingly. (diskfs_purge_lookup_cache): Likewise. (diskfs_check_lookup_cache): Likewise. Also, hard code a cache miss for the parent of the root directory and merge unlocking and releasing of node references.
2014-05-29libdiskfs: remove the statistics code from the name cacheJustus Winter
The current name cache lookup operation completes in O(n) time. This means that making the cache too large would decrease the performance. Therefore it was required to tune the size, hence the need for statistics. We will use a data structure with worst case constant lookup times in the future, removing the need to fine tune the cache size. * libdiskfs/name-cache.c: Remove the statistics code from the name cache.
2014-05-28trans/fakeroot: use netfs_node_netnode instead of np->nnJustus Winter
When using fat nodes, expressions of the form E->nn can be rewritten as netfs_node_netnode (E). This is much faster as it only involves a offset calculation. For reference, I used the following semantic patch to create the patch: @@ expression E; @@ - E->nn + netfs_node_netnode (E) * trans/fakeroot.c: Use netfs_node_netnode instead of np->nn.
2014-05-28trans/fakeroot: use fat nodes to simplify the node cacheJustus Winter
Previously, fakeroot stored netnodes in the hash table. But we are not interested in a cache for netnodes, we need a node cache. So fakeroot kept pointers to the associated node object in each netnode object. Use fat netfs nodes, which combine node and netnode objects. * trans/fakeroot.c (struct netnode): Remove np. (idport_ihash): Fix ihash location pointer offset. (new_node): Allocate fat nodes, store the node pointer in the hash table. (netfs_node_norefs): Adjust accordingly. (netfs_S_dir_lookup): Likewise.
2014-05-28libnetfs: add netfs_make_node_alloc to allocate fat nodesJustus Winter
libnetfs has two kind of nodes, struct node and struct netnode. struct node is used to store libnetfs specific data, while struct netnode contains user supplied data. Previously, both objects were allocated separatly, and a pointer from the node to the netnode provided a mapping from the former to the latter. Provide a function netfs_make_node_alloc that allocates both nodes in a contiguous region. This reduces the memory allocation overhead when creating nodes. It also makes the relation between node and netnode a simple offset calculation. Provide two functions to compute the netnode address from the node address and vice-versa. Most notably, this makes implementing a cache on top of libnetfs easier. Auxiliary data for the cache can be stored in the user-defined netnode, and the fat node can be used as the value. * libnetfs/make-node.c (init_node): Move initialization here. (netfs_make_node): Use init_node. (netfs_make_node_alloc): New function to allocate fat nodes. * libnetfs/netfs.h (netfs_make_node_alloc): New declaration. (_netfs_sizeof_struct_node): Likewise. (netfs_node_netnode): Compute netnode address from node address. (netfs_netnode_node): And vice-versa. * libnetfs/init-init.c (_netfs_sizeof_struct_node): New variable.
