* libdiskfs/dir-lookup.c (diskfs_S_dir_lookup): Rename identifiers to
be more idiomatic and closer to libnetfs and the interface
specification. Massage the code so that it aligns closer with the
dir_lookup server function in libnetfs. It should not change the
behavior.
|
|
* libnetfs/dir-lookup.c (netfs_S_dir_lookup): Rename 'diruser' to
'dircred'.
|
|
* libnetfs/dir-lookup.c (netfs_S_dir_lookup): Rename 'error' to 'err'.
|
|
* mach-defpager/default_pager.c (default_pager_thread): Fix panic
invocation.
|
|
* configure.ac (AC_INIT): Set version to 0.8.
* NEWS: Finalize for 0.8.
|
|
Changes missing from commit c9c29eb890527fe68900e4a0af7c2df9a9fa5b40.
* console-client/Makefile (%.so.$(hurd-version)): Use $(lpath) instead of
$(rpath)
* libstore/Makefile (libstore_%.so.$(hurd-version)): Likewise.

Fixes b04364bc. Thanks to Esa Peuha for spotting this.
* startup/startup.c (run): Fix blunder.
|
|
* libihash/ihash.c (hurd_ihash_locp_add): Also replace tombstones.
|
|
* libihash/ihash.c (hurd_ihash_locp_find): Set SLOT to NULL if the
hash table has not been allocated.
|
|
Amends d18ea50e.
* libtrivfs/fsys-getroot.c: When the user is privileged, make a
verbatim copy of the real node instead of making an auth-restricted
copy.
|
|
* trans/crash.c: Include <assert.h>.
|
|
Previously, if a hash table was not growing anymore but entries were
regularly replaced, the tombstones would accumulate slowing down
lookups and insertions. A possible solution is to rehash the table if
the effective load exceeds the configured threshold. The effective
load also takes tombstones into account.
* libihash/ihash.c (hurd_ihash_locp_add): Use the effective load.
(hurd_ihash_add): Likewise. Use the load to decide whether we want to
enlarge the table, otherwise we merely rehash.
|
|
* libihash/ihash.c (hurd_ihash_init): Init new field 'nr_free'.
(add_one): Decrement counter if a free slot is used.
(hurd_ihash_locp_add): Likewise.
(hurd_ihash_add): Reset counter on reallocation.
* libihash/ihash.h (struct hurd_ihash): New field 'nr_free'.
(hurd_ihash_get_effective_load): New function.
|
|
Previously, find_index would return a suboptimal slot if a tombstone
was in the optimal slot.
* libihash/ihash.c (find_index): Fix index computation.
|
|
* libtrivfs/fsys-getroot.c: When `uids` contain 0, make a verbatim copy of
the real node instead of making an auth-restricted copy.
|
|
This avoids the need to flush the buffer and works around a weird
problem with 'puts' not printing a newline.
* startup/startup.c: Write all messages to stderr.
|
|
* startup/Makefile: Set appropriate flags.
* startup/startup.c: Drop most stub functions.
|
|
* startup/startup.c: Add verbose parameter and inform about progress
through the bootstrap procedure if it is given.
|
|
* startup/Makefile: Build fs and io server with default
implementations.
(mung_msg_S.h): Tune regexp only to match the include guard.
* startup/startup.c (mig_reply_setup): New function.
(demuxer): Add new protocols. Nicer implementation.
(S_file_check_access): New function.
(S_io_restrict_auth): Likewise.
|
|
* doc/hurd.texi: Clarify what happens if 'trivfs_fsid' is zero.
* login/utmp.c: Leave 'trivfs_fsid' at zero.
* pfinet/main.c: Likewise.
* trans/ifsock.c: Likewise.
* trans/proxy-defpager.c: Likewise.
|
|
* libshouldbeinlibc/refcount.h: Use 'assert_backtrace'.
|
|
* libshouldbeinlibc/Makefile: Add new files
* libshouldbeinlibc/assert-backtrace.{c,h}: New files.
|
|
* libpager/demuxer.c: Include <assert.h>.
|
|
vm_offset_t (used by pager_memcpy) is not 64bit-ready yet. Reject requests
which go further than this.
* libdiskfs/io-seek.c (diskfs_S_io_seek): Return EFBIG when requested offset
is beyond limits of vm_offset_t.
* libdiskfs/rdwr-internal.c (_diskfs_rdwr_internal): Return EFBIG when
request goes beyond limits of vm_offset_t.
|
|
* ext2fs/inode.c (diskfs_user_read_node): When sizeof(off_t) >= 8, add
di->i_size_high as high-64bit part to st->st_size. Drop setting
unused info->i_high_size.
(write_node): When sizeof(off_t) >= 8, write high-64bit part of st->st_size
to di->i_size_high.
* ext2fs/ext2_fs_i.h (ext2_inode_info): Remove i_high_size field.
* pfinet/linux-src/include/linux/ext2_fs_i.h (ext2_inode_info): Likewise.

Set 'is_root' if the node has been opened by the root user (this was
the old behavior) or if it has been opened by the user the translator
is executing under.
This fixes the irritating bug that an unprivileged user cannot control
her own trivfs-based translators. It does not change how privileged
trivfs translators work.
* libtrivfs/io-reauthenticate.c (trivfs_S_io_reauthenticate): Use the
new function to compute 'isroot'.
* libtrivfs/io-restrict-auth.c (trivfs_S_io_restrict_auth): Likewise.
* libtrivfs/open.c (trivfs_open): Likewise.
* libtrivfs/priv.h (_is_privileged): New function.
* libtrivfs/trivfs.h (struct peropen): Clarify what 'isroot' means.
|
|
* libtrivfs/times.c (trivfs_set_{a,m}time): Fix error handling.
|
|
* libdiskfs/boot-start.c (diskfs_start_bootstrap): Improve error
handling.
|
|
|
|
* libnetfs/dir-mkfile.c (netfs_S_dir_mkfile): Keep flags out of
OPENONLY_STATE_MODES, instead of flags of OPENONLY_STATE_MODES, for the
peropen's openstat.
|
|
Previously, NULL was passed as cookie. That notably caused some
'peropen' objects to be created without context.
Fixes 0bb14d0b.
* libfshelp/fetch-root.c (fshelp_fetch_root): Pass cookie to the
callback function.
|
|
* mach-defpager/default_pager.c (S_default_pager_storage_info): Fix
error handling.
|
|
* sutils/Makefile ($(prefix)/dev/MAKEDEV): Add -f to ln command.
|
|
* utils/settrans.c (options): Add '--underlying'.
(main): Handle new option.
(open_node): Open the node if given.
|
|
* utils/settrans.c (get_credentials): New function.
(main): Get an authenticated root node for the process we are
chrooting.

unsigned32_t.

When /dev/hd* entries are parted-partition storeio, the store name is only
the disk name, thus not unique. We should just use the path being used
instead.
* sutils/swapon.c (swaponoff): Use `file' instead of `store->name' to
default_pager_paging_file.
(main): Drop hardcoded "/dev/".
* procfs/rootdir.c (rootdir_gc_swaps): Drop hardcoded "/dev/".
|
|
* procfs/rootdir.c (rootdir_gc_swaps): Fix default_pager_storage_info call
parameter order.
* sutils/swapon.c (main): Likewise.

* libnetfs/make-node.c: Initialize refcounts in refcounts_init.

netfs_node_refcnt_lock. Add netfs_nref_light, netfs_nrele_light and
handler netfs_try_dropping_softrefs. Adjust comments.
* libnetfs/nput.c: Use refcounts_t. Call netfs_try_dropping_softrefs to
remove any soft reference that the translator might have acquired
during the lifetime of the node. Implement empty
netfs_try_dropping_softrefs.

hash table.

netfs_try_dropping_softrefs to remove the node from the hash table.
* trans/fakeroot.c (netfs_node_norefs): Remove code to remove the node
from the hash table.
* trans/fakeroot.c (netfs_S_dir_lookup): Simplify lookup code since we
don't need to lock netfs_node_refcnt_lock anymore.
* procfs/netfs.c: Remove use of netfs_node_refcnt_lock.
* nfs/cache.c: Add mutex to handle exclusive access to nodehash. This
replaces the use of netfs_node_refcnt_lock.

nodehash. Use netfs_nref_light to add one soft reference to the node
just added to nodehash.
* nfs/cache.c (netfs_node_norefs): Use netfs_nref. Don't use
netfs_node_refcnt_lock and don't remove the node from nodehash here.
* nfs/cache.c (netfs_try_dropping_softrefs): Drop the light reference
when the node has no more hard references.

soft references remove node pointer from the fields above.

bash's '<(' helper creates a pipe and gives /dev/fd/63 to the program, and
gcc would then run access() on it. So we actually need to support at least
some FS operations on pipes.

FILE_IMPORTS): New macros.

|
|
* ext2fs/pager.c (disk_cache_info_free_push): Add prototype.
(disk_pager_notify_evict): When dropping DC_INCORE flag, if the
block becomes free (no reference and no DC_DONT_REUSE flags), call
disk_cache_info_free_push.
(disk_cache_block_deref): Only call disk_cache_info_free_push if the flags
of the block do not contain DC_DONT_REUSE flags.
