libtrivfs contains two ways of managing more than one port class and
bucket. There is the old way of using a statically allocated array
with explicit length, and the new way with dynamically allocated
vectors.
Converting all users to the new way of handling multiple classes
and/or buckets, we can simplify the code in libtrivfs. In many cases,
the code will be simpler and more expressive for the user.
This also fixes a severe bug. As no classes are given to
`trivfs_startup', they are created and inserted into the dynamic
vector of classes. The server function `trivfs_S_fsys_forward',
however, used the first item of the previously used static array,
which is NULL. This circumvented the typecheck.
* trans/magic.c: Convert to dynamic classes and buckets.

* libdiskfs/boot-start.c (start_execserver): fflush stdout when pausing.
|
|
* libdiskfs/boot-start.c (start_execserver): Improve error handling.
|
|
* exec/main.c: Include `argz.h'.
|
|
* libports/inhibit-all-rpcs.c (ports_inhibit_all_rpcs): Remove unused
variable `bucket'.
* libports/inhibit-class-rpcs.c (ports_inhibit_class_rpcs): Remove unused
variables `pi' and `rpc'.
|
|
* exec/elfcore.c (TIME_VALUE_TO_TIMESPEC) [TIME_VALUE_TO_TIMESPEC]: Do not
redefine macro.
|
|
Thanks Svante Signell for the investigation.
* pflocal/socket.c (S_socket_connect, S_socket_send): When addr_get_sock
returns EADDRNOTAVAIL, translate into ECONNREFUSED.
|
|
* pflocal/sock.h (sock_bind): Move declaration.
|
|
This adds support for CSI s and u, which are equivalent to ESC 7 and 8,
saving/restoring the cursor position.
* console/display.c (handle_esc_bracket): Added support for CSI s and u.
|
|
* libpipe/pipe.c (_pipe_no_readers): Break pipe for connection-less pipes
too.
|
|
Since bound socks always have a ref for their address, they would never get
freed. Thanks Svante Signell for the investigation.
* pflocal/sock.h (sock_deref): When `sock' has one ref left and is bound to
an address, unbound it, and thus shut it down.
|
|
* pflocal/sock.c (sock_bind): When addr is NULL, do not take/release its
mutex. When old_addr is also NULL, return EINVAL. When old_addr is not NULL,
deref old_addr instead of addr.
|
|
* libports/Makefile (installhdrs): Add port-deref-deferred.h for ports.h
|
|
They were not usable anyway.
* libtrivfs/Makefile (installhdrs): Remove generated mig stub headers.
|
|
* libshouldbeinlibc/maptime.h (maptime_read): Use memory fences.
|
|
* pflocal/io.c (copy_time): Move function out of `S_io_stat', turning
it into a static inline function.
|
|
This fixes umounting bind mounts or other mounts for which the device can
not be made away.
* utils/umount.c (do_umount): When the --force option is not passed, ignore
errors from file_set_translator call on the device file.
|
|
* sutils/fstab.c (fstab_find_device): Do not realpath "proc" pseudo-device.
|
|
This allows "mount none /proc -t proc" to work.
* procfs/main.c (argp_parser): On ARGP_KEY_ARG, accept and ignore "none" and
"proc".
|
|
We should not wait for a writer in that case, since that will be ourself.
* trans/fifo.c (open_hook): Do not wait for a writer when flags contains
O_WRITE.

On some systems, ext2fs.static would regularly hang at startup, as a
race condition meant it would process paging requests while remounting.
To fix this, libpager has been altered to allow inhibiting and resuming
its worker threads, and ext2fs uses this to inhibit paging while
remounting.
* console/pager.c (pager_requests): New variable.
(user_pager_init): Updated call to pager_start_workers to use new
pager_requests variable.
* daemons/runsystem.sh: Removed artificial delay working around the race
condition.
* ext2fs/ext2fs.c (diskfs_reload_global_state): Call new
inhibit_ext2_pager and resume_ext2_pager functions, and leave sblock as
non-NULL so it will be munmapped.
* ext2fs/ext2fs.h (inhibit_ext2_pager,resume_ext2_pager): New functions.
* ext2fs/pager.c (file_pager_requests): New variable.
(create_disk_pager): Updated call to pager_start_workers to use new
file_pager_requests variable.
(inhibit_ext2_pager,resume_ext2_pager): New functions.
* fatfs/fatfs.h (inhibit_fat_pager,resume_fat_pager): New functions.
* fatfs/pager.c (file_pager_requests): New variable.
(create_fat_pager): Updated call to pager_start_workers to use new
file_pager_requests variable.
(inhibit_fat_pager,resume_fat_pager): New functions.
* libdiskfs/disk-pager.c (diskfs_disk_pager_requests): New variable.
(diskfs_start_disk_pager): Updated call to pager_start_workers to use
new diskfs_disk_pager_requests variable.
* libdiskfs/diskfs-pager.h (diskfs_disk_pager_requests): New variable.
* libpager/demuxer.c (struct pager_requests): Renamed struct requests to
struct pager_requests. Replaced queue with queue_in and queue_out
pointers. Added inhibit_wakeup field.
(pager_demuxer): Updated to use new queue_in/queue_out pointers. Only
wake up workers if not inhibited.
(worker_func): Updated to use new queue_in/queue_out pointers. Final
worker thread to sleep notifies the inhibit_wakeup condition variable.
(pager_start_workers): Added out parameter for the requests instance.
Allocate heap space shared by both queues. Initialise new inhibit_wakeup
condition.
(pager_inhibit_workers,pager_resume_workers): New functions.
* libpager/pager.h (struct pager_requests): Public forward definition.
(pager_start_workers): Added out parameter for the requests instance.
(pager_inhibit_workers,pager_resume_workers): New functions.
* libpager/queue.h (queue_empty): New function.
* storeio/pager.c (pager_requests): New variable.

* libthreads/lockfile.c (_IO_MTSAFE_IO): Define macro.
(IS_IN): Define macro to 0.
|
|
* libdiskfs/dir-lookup.c (diskfs_S_dir_lookup): Rename `error' to `err'.
* libdiskfs/file-getcontrol.c (diskfs_S_file_getcontrol): Likewise.
* libdiskfs/file-syncfs.c (diskfs_S_file_syncfs): Likewise.
|
|
* libdiskfs/diskfs.h (diskfs_node_disknode): Add missing declaration.
(diskfs_disknode_node): Likewise.
|
|
* libdiskfs/diskfs.h: Fix typo.
|
|
* libdiskfs/name-cache.c (diskfs_check_lookup_cache): Drop stray negation.
|
|
* ext2fs/ext2fs.h (ext2_debug_): New macro that unconditionally prints
the given message.
(ext2_debug): Use the new macro.
|
|
* ext2fs/ext2fs.h (ext2_debug): Print to stderr.
(printf): Drop declaration.
|
|
Otherwise some scripts may try to modify system files just because they find
they seem to be able to.
* trans/fakeroot.c (netfs_report_access): When FAKE_MODE is not set on
`np', call file_check_access on the underlying node instead of returning
O_RDWR|O_EXEC.
|
|
Fakeroot does not support faking them anyway, and they may change on the
underlying fs, e.g. when creating a local socket.
* trans/fakeroot.c (netfs_validate_stat): Return S_IFMT part of st_mode as
provided by underlying filesystem.

The Hurd uses protected payloads to improve the receiver lookup on the
server side to the point that we no longer do a hash table lookup in
the dispatch code.
If the kernel does not support protected payloads, we degrade
gracefully, do one lookup in libports' dispatching code, and emulate
the protected payload feature to still save one hash table lookup in
the intrans function.
* libports/manage-multithread.c (ports_manage_port_operations_multithread):
Add comment.
* libports/manage-one-thread.c (ports_manage_port_operations_one_thread):
Likewise.
|
|
* pflocal/mig-decls.h (begin_using_addr_payload): Use
`ports_lookup_payload'.
|
|
* init/init.c (main): On execv failure, print which path failed.
|
|
Previously, the exec server did not set the name of the servers
started before the proc server. Instead this was done by the startup
server, but this was merely a workaround, missing notably the startup
server itself.
* exec/exec.c (set_name): New function.
(do_exec): Move the code setting the name to a new function, and also
call it if the proc server is not started yet.
* startup/startup.c (run): Drop hack.
|
|
* libdiskfs/io-reauthenticate.c (diskfs_S_io_reauthenticate): Release the node
lock while blocking on the auth server and client.
* libnetfs/io-reauthenticate.c (netfs_S_io_reauthenticate): Likewise.
* pfinet/io-ops.c (S_io_reauthenticate): Likewise.
|
|
* utils/rpcscan.c: New file.
* utils/Makefile: Add `rpcscan'.
|
|
* utils/rpctrace.c: Move all the code handling the message id files...
* utils/msgids.c: ... to a new file.
* utils/msgids.h: And add the relevand declarations.
* utils/Makefile (SRCS): Add the new file.
|
|
As well as other potential mode changes which are indeed supposed to still
work as root.
* trans/fakeroot.c (netfs_attempt_chmod): Always set S_IRUSR and S_IWUSR in
real_mode, and set S_IXUSR also when this is a directory.
|
|
* libps/fmt.c (_fmt_create): When nothing at all was recognized, break out
instead of looping.
|
|
* libdiskfs/node-cache.c (diskfs_node_iterate): Do not print a message
on ENOMEM.
|
|
* configure.ac: test whether AWK provides strtonum function.

To prevent infinite recursion range checking was introduced
as an exit condition adding two extra comparisons on each
recursive call.
By fixing the range used by the recursive call over the lower
half of the array one can avoid penalizing successful lookups
while still preventing infinite recursion due to `first`
parameter being greater than `last` parameter.
* console-client/xkb/kstoucs.c (find_ucs): don't remove middle from the
lower range. Remove extra comparisons.
|
|
* console-client/xkb/kstoucs.c (find_ucs): assert precondition.
|
|
Previously, the `vmstat' utility would stop displaying the memory
object hit ratio after some time due to an integer overflow.
* utils/vmstat.c (get_memobj_hit_ratio): Fix integer overflow.
|
|
* utils/Makefile: Link against `libshouldbeinlibc'.
