DEC disk boot block header, but it's only 64 bytes long. Gives us
another 32 bytes in the first stage.
Don't use a roll-your-own START_FRAME size and offsets for the stack
and ra - use the <mips/asm.h> provided CALLFRAME_SIZ, CALLFRAME_RA and
CALLFRAME_SP
* Add prototype to libkern.h.
* Remove the almost-identical-copy from libsa/net.[ch].
* Change its type back to the (wrong, but harmless) historical one. (u_long)
* Kill the XXX local prototype in nfs_bootparam.c
if the version number is higher than we know about. This allows, e.g.,
changes in the format of the ifile, segment size restrictions and boundaries,
etc., which would not affect existing fields in the superblock, but which
would drastically affect the filesystem, to be smoothly integrated at a
later date.
on (nodes which are not marked IN_MODIFIED/IN_CLEANING, but which have dirty
buffers), by marking them with the appropriate flag if dirtybuffers were added
while the write was in progress.
conditions. Also change the default setting of lfs_clean_vnhead to 0, which
seems to make the locking problems go away (although this is difficult to
test as I can't reliably reproduce them).
then immediately reloaded, their dinodes were located in an inode block
which was not on disk at the advertized location, nor in the cache (although
it would be flushed to disk next segment write). Fix this by using getblk()
instead of lfs_newbuf() for inode blocks.
for the first write. If this is not done, the cleaner may try to clean the
current segment out from under the writer if the filesystem is mounted after
a crash (or any other time that the dirty:clean segment ration is high enough).
enter partitions offet and size. The user can chose unit independantly of
the unit used for display ('M'/'c'/'s'). These functions do the proper
bound checks and alignement/roudups. Used in the edfspart menu and
i386 md_make_bsd_partitions() (other ports should do the change as
well).
- now that getpartsize() does the rigth thing, kill the swapadj hack (which was
buggy anyway).
- in i386 md_make_bsd_partitions(), don't propose defaults that don't fit on
the disk. If the disk is too small, fallback to custom instead.
- fix a bug in mbr.c, where the partition flags would not have always been
reset. sysinst created me a MBR with 2 active partition. The boot code
doesn't like it :)
- added a message for eventual mount failures.
- killed donewfs and extracting messages, as we run the commands in a
subwindow these messages just flashed on the screen.
- Changes a few exit(1) to return(1), to give the user a second chance.
- added msg_clear() or wclear(stdscr) in a place or two, to make
display a bit nicer.
- in run_cmd(), if the command succeeded, don't wait for the user to
press enter.
- Don't rely on ATA signature: some ide controllers seems to not transmit it
properly (SIMIDE on arm32 machines). Instead, when we guess a drive is here
after reset, just mark it as ATA and OLD is it's not ATAPI.
- at attach time, use IDENTIFY to eliminate ghost from the probe. If the
drive had the old flag and IDENTIFY failed, issue a WDCC_RECAL command
to detect a pre-ATA disk. If IDENTIFY succeded, remove the OLD flag,
it's obviously not a pre-ATA disk.
- add a new controller flag, WDC_CAPABILITY_PREATA, used to shorcut parts
of the probe (not necessary, but makes the probe/attach faster). This is
only set by the ISA front-end, all other controllers supported can't have
pre-ATA drives attached.
The mechanism used are more or less the same as before, they have just been
reordered. Should solve port-arm32/7324 (waiting for feedback).
DoS attacks (e.g. looping packets between two echo ports).
This should "fix" PR bin/2455.
Could please anyone with an appropriate "hacker tools" check this?
define a flag UVM_PGA_USERESERVE to allow non-kernel object
allocations to use pages from the reserve.
use the new flag for allocations in pmap modules.
