0a9c130c06 Introduce a g_waitfor_event() function which posts an event and waits for 
it to be run (or cancelled) and use this instead of home-rolled versions.

a974614b05 More of the event stuff can now be private to geom_event.c 2003-04-23 20:54:42 +00:00

8cd1535a24 Rename g_call_me() to g_post_event(), and give it a flag 
argument to determine if we can M_WAITOK in malloc.

ca3d750e73 Introduce gctl_get_paraml() which gets a parameter only if it has the

b874183561 Change the locking so that the _modify function is called with topology 
held.

The only place where we want to not hold topology is when we read
(or write) the label to disk: in the case of a disk error with a
long recovery time, holding topology would prevent open/close of
any disk device.

b09d72daf8 We don't need to have a slice->start() function. 2003-04-22 21:24:37 +00:00

d3a1a13766 Do not mandate that slicers have a private ->start(), they may not need 
one.  KASSERT() that they have one if G_SLICE_HOT_START is used.

989afda211 Implement a hotspot for the sunlabel. 
This means that you can no longer trash your opened partitions by writing to
the sunlabel through another partition.  This is similar to the semantics
implemented for BSD labels.

666223979c Update GEOM::SUN to use the decoding functions in geom_sunlabel_enc.c 
and #defines from sys/sun_disklabel.h.

structures.

7220a9e779 Make more of the "hotspot" stuff generic: 
Give the class a way to specify the necessary action for read/delete/write:
ALLOW, DENY, START or CALL.

Update geom_bsd to use this.
 2003-04-19 10:14:39 +00:00

183a45f65e Create a dedicated structure for holding hotspot information rather than 
using slice structures for it.

c72e7314c2 These two files fell off during my previous commit: put the encoding 
decoding functions for struct disklabel in a separate .c file.

7715475960 More correct patch: Only call biofinish if we have not already sent 
any children down the mesh.

3924ad705e Time has run from the "run GEOM in userland" harness, and the new regression 
test is built to test GEOM as running in the kernel.

This commit is basically "unifdef -D_KERNEL" to remove the mainly #include
related code to support the userland-harness.

537d9274dc If we hit access ahead of a spoil event, we should have negative

5f5a9022b2 Retire the experimental bio_taskqueue(), it was not quite as usable as 
hoped.  It can be revived from here, should other drivers be able to
use it.

0d3e96e39c Retire the "frontstuff" record keeping, it was no match for the 
in-band meta-data of BSD labels and a more complex solution will be needed.

6e03422af0 Move the functions for encoding decoding struct dos_partition into 
a separate .c file so they can be used from userland as well.

551e52efb8 With the magic sequence checks removed this class is downright dangerous 
to have in your kernel since it indiscriminately attaches to anything
it is offered with a range of bogus partitions.

Stop this from happening by rejecting any label with negative numbers in
it.

316aed030e Add handling for cancelled events in the g_call_me() methods. 2003-04-02 21:10:04 +00:00
Poul-Henning Kamp
afcbcfaed0 Change events to have an array of "void *" references, and give the 
event posting functions varargs to fill these.

Attribute g_call_me() to appropriate g_geom's where necessary.

Add a flag argument to g_call_me() methods which will be used to signal
cancellation of events in the future.

This commit should be a no-op.

c7e1925c7c Properly handle races between open/close and orphan. 
KASSERT the race between close and strategy, it is an error in the upper
echelons if this happens,

Add XXX: comment explaining why the ioctl/orphan race is not closed.
