The task_set_name RPC introduced in 877a319c changed
include/mach/gnumach.defs to include mach_debug/mach_debug_types.defs.
Previously though, the debug headers were not installed.
* Makefrag.am: Install the mach_debug header files.
|
|
The number of priorities has been changed from 32 to 50 in
6a234201081156e6d5742e7eeabb68418b518fad.
* doc/mach.texi: Update accordingly.
|
|
* configure.ac (MIG): Error out if MiG was not found.
|
|
* kern/bootstrap.c (boot_script_task_create): Set the name of newly
created tasks.
|
|
Previously, every userspace server implementing the device protocol
filtered the device definitions to replace the device_t type with
mach_port_send_t to make the device argument of device_open
polymorphic. Rather than doing that, which makes it impossible to use
translation functions, fix the definition of device_open.
* include/device/device.defs (device_open): Redefine the device
argument to make it polymorphic unless a outran function is specified.
|
|
Make the intran, outtran and destructor functions mutable using
preprocessor macros. Make it possible to inject imports using the
DEVICE_IMPORTS macro. This way, userspace servers can provide their
own translation functions.
* include/device/device_types.defs: Honor DEVICE_IMPORTS.
(device_t): Make the translation mutable using preprocessor macros.
|
|
Make the intran, outtran and destructor functions mutable using
preprocessor macros. Make it possible to inject imports using the
NOTIFY_IMPORTS macro. This way, userspace servers can provide their
own translation functions.
* include/mach/notify.defs: Honor NOTIFY_IMPORTS.
(notify_port_t): Make the translation mutable using preprocessor macros.

CGA and MONO cards are more than hard to find nowadays, and some buggy BIOSes
claim running them nowadays...
* i386/i386at/kd.c (kd_xga_init): Do not handle CGA and MONO cases any
more, which thus default to EGA/VGA.
|
|
* i386/i386at/kd.c (kd_xga_init): Use CM_EGA_VGA behavior as default
case for unknown values of CMOS data.

Previously, bootstrap_create would print the multiboot modules with
padding applied to the end of the line. As multiboot modules as used
by the Hurd span more than one line. This makes the list of modules
hard to read and it looks unclean, more like an accident.
Furthermore, it is not clear what the intend of this was, as the
padding is applied at the end of the line, with no further information
printed thereafter.
* kern/bootstrap.c (bootstrap_create): Remove variable maxlen and len,
update printfs.

Make the intran, outtran and destructor functions mutable using
preprocessor macros. Make it possible to inject imports using the

mutable using preprocessor macros.

We were filling much more than the mapwindows array, thus overwriting in
at least debugger variables.
* i386/intel/pmap.c (pmap_bootstrap): Make sure to limit mapwindows
initialization within PMAP_NMAPWINDOWS.

Previously, the error KERN_RESOURCE_SHORTAGE was not properly
propagated.

PCI devices expose their memory etc. way beyond last_phys_addr. Userland
drivers opening /dev/mem need to open those too, even if phystokv() will
not work for them.

(pmap_zero_page, pmap_copy_page, copy_to_phys, copy_from_phys): Use
`pmap_get_mapwindow' to temporarily map physical pages beyond last_phys_addr.

Previously, the function mig_strncpy would always zero-terminate the
destination string. Make mig_strncpy behave like mig_strncpy and
strncpy in the glibc. Also fix the implementation of mig_strncpy to
return the length of the written string to align the implementation
with the declaration in include/mach/mig_support.h.
* kern/ipc_mig.c (mig_strncpy): Do not zero-terminate the destination
string. Return length of destination string.

set.

quiet flag of the request is not set.

request is non-zero.
(cdrom_end_request): Do not print sense results when `quiet' field of
request is non-zero.
(cdrom_check_status, cdrom_read_capacity, cdrom_read_tocentry): Pass 1 to
`cdrom_queue_packet_command''s `quiet' parameter.
(cdrom_lockdoor, cdrom_eject, cdrom_pause, cdrom_startstop,
cdrom_read_subchannel, cdrom_mode_sense, cdrom_mode_select,
cdrom_play_lba_range_1, cdrom_read_block, cdrom_load_unload,
ide_cdrom_ioctl): Pass 0 to `cdrom_queue_packet_command''s `quiet' parameter.
|
|
* linux/src/drivers/block/ide.c (ide_init_drive_cmd): Initialize `quiet'
field of request to 0;
|
|
|
|
This avoids grub & such making Mach print flurries of floppy errors.
* linux/dev/include/linux/blkdev.h (request): Add `quiet' field.
* linux/dev/include/linux/blk.h (end_request): Print I/O error only if

* linux/dev/drivers/block/floppy.c (floppy_revalidate): Pass 1 to
`ll_rw_block''s `quiet' parameter.

In addition to physical pages, the slab allocator also consumes kernel
virtual memory, so reclaim pages on failure to allocate from a kernel map.
This method isn't foolproof but helps alleviate fragmentation.
* vm/vm_kern.c (kmem_alloc): Call slab_collect and retry allocation
once on failure.
(kmem_realloc): Likewise.
(kmem_alloc_wired): Likewise.
(kmem_alloc_wired): Likewise.

* doc/mach.texi (Task Information): Document the new task_set_name
procedure.
|

task_set_name sets the name of a task. This is a debugging aid. The
name will be used in error messages printed by the kernel.
* include/mach/gnumach.defs (task_set_name): New procedure.
|
|
task_set_name sets the name of a task. This is a debugging aid. The
name will be used in error messages printed by the kernel.

Previously, only strlen(device_name) bytes were allocated, missing one
byte for the terminating zero.
* xen/block.c (hyp_block_init): Fix buffer size.

Use strncpy instead of strcpy to copy the name of a symbol into the
symtab structure. Make sure that the string is properly terminated.
Found using Coverity.
* ddb/db_sym.c (db_add_symbol_table): Use strncpy instead of strcpy,
ensure string termination.

The slab allocator relies on the fact that kmem_cache_error does not
return. Previously, kmem_error was using printf. Use panic instead.
Found using the Clang Static Analyzer.
* kern/slab.c (kmem_error): Use panic instead of printf.
