(vga_init): Save attribute mode subregister content. Re-enable the
screen after that.
(vga_fini): Restore attribute mode subregister content. Re-enable the
screen after that.
(vga_set_font_width): When the font width is set to 9, enable VGA LGE to
properly handle box-drawing unicode characters. Re-nable the screen
after that.
(vga_exchange_palette_attributes): Use VGA_ATTR_ENABLE_ADDR macro
instead of harcoded 0x20.

When a client finds a node from the hash table, it could happen that
another thread is still holding one reference on it before the current
thread has acquired its own. Simply checking for a non zero refcount isn't
enough, the new client must atomically acquire its own reference.
* trans/fakeroot.c (netfs_S_dir_lookup): Find and acquire node reference
while holding netfs_node_refcnt_lock.
|
|
* trans/fakeroot.c (netfs_S_dir_lookup): Fix node dereference.
|

Instead of the FAKE_REFERENCE flag, rework node caching so that nodes are
retained only if their attributes are actually changed. In addition, don't
remove unreferenced nodes from the hash table at protid release, since
their reference counter is unstable. Do it on node destruction, once the
reference counter has reached 0. This means lookups can return nodes not
referenced (other than by the hash table), a condition for which a check
is added. By never acquiring a reference on such nodes, their counter is
guaranteed to remain stable once unreferenced.
* trans/fakeroot.c (FAKE_REFERENCE): Remove macro.
(FAKE_DEFAULT): New macro.
(set_default_attributes): New function.
(set_faked_attribute): Likewise.
(netfs_node_norefs): Remove node from hash table, properly taking care
of all the locks involved.
(fakeroot_netfs_release_protid): Remove node handling code, merely call
netfs_release_protid.
(netfs_S_dir_lookup): Handle unreferenced nodes, call set_default_attributes
on node creation, remove call to netfs_attempt_chown.
(netfs_attempt_chown): Call set_faked_attribute instead of accessing faked
flags directly.
(netfs_attempt_chauthor): Likewise.
(netfs_attempt_chmod): Likewise.

Unconditionally relay chmod requests instead of filtering those that
don't change the executable bit.
* trans/fakeroot.c (netfs_attempt_chmod): Unconditionally call file_chmod
with an unaltered mode.
|

This reverts commit 672005782e57e049c7c8f4d6d0b2a80c0df512b4.
That change is apparently not needed and introduced a deadlock.
* trans/fakeroot.c (netfs_attempt_mkfile): Unlock directory node before
creating new node.
|
|
* trans/fakeroot.c (netfs_S_dir_lookup): Deallocate rights to intermediate
file systems.

(print_banner): Print a newline.
|
|
* exec/main.c (S_exec_init): Get the device master port and connect
std{in,out,err} to the mach console.
|
|
Previously, a banner was hardcoded in Hurds getty. Load /etc/issue
instead. Fall back to a hardcoded version if that fails. Expand
common \char sequences. If no /etc/issue is provided, the old
behavior is retained.
* daemons/getty.c (load_banner): New function.
(print_banner): Expand \char sequences.
|
|
* pfinet/options.c (add_dev_opts): Use a for loop over `idev->addr_list'
instead of a while loop which assumes that it is not empty.
|
|
* pfinet/ethernet.c (ethernet_close): Call mach_port_deallocate on
device port.
|
|
* pfinet/ethernet.c (ethernet_xmit): Also call ethernet_close then
ethernet_open on EMIG_SERVER_DIED error.
|
|
|
|
* pfinet/ethernet.c (ethernet_close): New function.
(ethernet_xmit): On EMACH_SEND_INVALID_DEST error, call ethernet_close
and ethernet_open again to re-open ethernet device.
|
|
* libnetfs/release-peropen.c (netfs_release_peropen): Release the lock on
the underlying node if the peropen status indicates it's not unlocked.
|

The canonical name for variables of the type error_t is err. There
are, however, places where the variable is called error instead. This
is unfortunate, as this shadows the error function. Rename such
variables to err.
For reference, this is accomplished using the following semantic
patch:
@@
expression E;
@@
-error_t error = E;
+error_t err = E;
<...
-error
+err

Introduce PSTAT_TIMES to force the retrieval of both PSTAT_TASK_BASIC
and PSTAT_THREAD_BASIC. Task basic info contain the user and system
times of terminated threads which the code wrongly assumes is always
present along with process info.
* libps/procstat.c (add_preconditions): Set both PSTAT_TASK_BASIC and
PSTAT_THREAD_BASIC as preconditions for PSTAT_TIMES.
(summarize_thread_basic_info): Add terminated threads times only if
task basic info are available.
(set_procinfo_flags): Provide summarize_thread_basic_info with flags of
available info.
(proc_stat_set_flags): Set PSTAT_TIMES as available if it was needed and
any of PSTAT_TASK_BASIC or PSTAT_THREAD_BASIC could be fetched.

To detect if an active translator goes away, we need to register for
dead name notifications. Those notifications have to be sent to a port
known to the ports library, as the ports library handles the dead name
notifications. The most straight forward way is to use the port to the
underlying node for that. To that end, a reference to the port_info
struct is handed in and kept in the list of active translators.
This commit also moves the registration of dead name notifications to
libfshelp.
* libfshelp/fshelp.h (fshelp_set_active_translator): Add port_info argument.
* libfshelp/translator-list.c (struct translator): Add port_info pointer.

Traditionally, /proc/mounts includes only filesystem mount points.
Previously though, the mtab translator included any kind of
translator, like all /hurd/storeio translators. This causes problems
with umount --all as this would remove the passive translator records
from nodes in /dev.
Fix this by only listing filesystem-like translators by default.
Filesystem-like translators are identified by their response to
dir_readdir messages sent to their root node.
* trans/mtab.c (all_translators): New variable.
(options): Add flag to preserve the old behavior.
(parse_opt): Handle the new flag.
(is_filesystem_translator): New function.
(mtab_populate): Skip non-filesystem translators by default.

* trans/mtab.c (main): Use ports_manage_port_operations_multithread.

* trans/mtab.c (struct mtab): Add lock.
(open_hook): Initialize lock.
(close_hook): Destroy lock.
(trivfs_S_io_read): Lock mtab object, adjust error handling accordingly.

Previously the mtab detector tried to detect whether it talks to
itself by comparing the control port of the translator it currently
visits with its own. This was done to prevent deadlocks. However, this
did not detect non-trivial loops, i.e. two mtab translators would
still dead-lock each other.
Now that it is safe to actually file_name_lookup the root node of a
mtab translator without triggering the generation of content, this
logic can just be omitted.
* trans/mtab.c (mtab_populate): Remove the loop detection logic.
|
|
Previously the mtab content was generated in the open hook. Delay this
until the data is needed. A follow up patch will take advantage of
this to both simplify the logic in mtab_populate and make it more
robust at the same time.
* trans/mtab.c (open_hook): Do not eagerly populate the mtab.
(trivfs_S_io_read): Populate the mtab struct on demand.
(trivfs_S_io_seek): Likewise.
(trivfs_S_io_readable): Likewise.

Include the run time of terminated threads in the user and system times
of processes.

Setting the stack size should now correctly be supported by libpthread.
* libports/manage-multithread.c (__pthread_stack_default_size): Remove
global variable.

Previously, fakeroot would not exit if a process outlived the original
process started by settrans. This caused bugs like this:
% fakeroot-hurd /bin/sh -c 'sleep 1&' 2>&1 | tee
<hangs>
Fix this by exiting if the last client of fakeroot goes away.
If noone has a right to any control or protid port, noone can ever
reacquire any such right. So it is safe to shutdown the fakeroot
translator in that case.
* trans/fakeroot.c (fakeroot_netfs_release_protid): Shutdown the
translator if the last protid object is destroyed and no control port
is around either.

Currently, it is impossible to properly attribute response messages to
requests. Even though rpctrace is single-threaded, its tracee may
not. Or there might be more than one tracee. In any such case it is
not guaranteed that the reply message we just processed is for the
request we just printed. Fix this by printing ellipsis with the port
name, so that reply messages can be properly attributed:
task129(pid3312)->mach_port_allocate (3) ...134
task129(pid3312)->mach_port_deallocate (pn{ 1}) ...160
134... = 0 pn{ 30}
160... = 0
* utils/rpctrace.c (last_reply_port): New variable.
(print_ellipsis): New function.

last_reply_port.
