sunvdc: add cdrom and v1.1 protocol support Interpret the media type from v1.1 protocol to support CDROM/DVD. For v1.0 protocol, a disk's size continues to be calculated from the geometry returned by the vdisk server. The geometry returned by the server can be less than the actual number of sectors available in the backing image/device due to the rounding in the division used to compute the geometry in the vdisk server. In v1.1 protocol a disk's actual size in sectors is returned during the handshake. Use this size when v1.1 protocol is negotiated. Since this size will always be larger than the former geometry computed size, disks created under v1.0 will be forwards compatible to v1.1, but not vice versa.

Drivers: block: remove __dev* attributes. CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

vio: fix reuse of vio_dring slot vio_dring_avail() will allow use of every dring entry, but when the last entry is allocated then dr->prod == dr->cons which is indistinguishable from the ring empty condition. This causes the next allocation to reuse an entry. When this happens in sunvdc, the server side vds driver begins nack'ing the messages and ends up resetting the ldc channel. This problem does not effect sunvnet since it checks for < 2. The fix here is to just never allocate the very last dring slot so that full and empty are not the same condition. The request start path was changed to check for the ring being full a bit earlier, and to stop the blk_queue if there is no space left. The blk_queue will be restarted once the ring is only half full again. The number of ring entries was increased to 512 which matches the sunvnet and Solaris vdc drivers, and greatly reduces the frequency of hitting the ring full condition and the associated blk_queue stop/starting. The checks in sunvent were adjusted to account for vio_dring_avail() returning 1 less. Orabug: 19441666 OraBZ: 14983 Signed-off-by: Dwight Engen <dwight.engen@oracle.com> Signed-off-by: David S.

treewide: setup_timer() -> timer_setup() This converts all remaining cases of the old setup_timer() API into using timer_setup(), where the callback argument is the structure already holding the struct timer_list. These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

block: introduce new block status code type Currently we use nornal Linux errno values in the block layer, and while we accept any error a few have overloaded magic meanings. This patch instead introduces a new blk_status_t value that holds block layer specific status codes and explicitly explains their meaning. Helpers to convert from and to the previous special meanings are provided for now, but I suspect we want to get rid of them in the long run - those drivers that have a errno input (e.g. networking) usually get errnos that don't know about the special block layer overloads, and similarly returning them to userspace will usually return somethings that strictly speaking isn't correct for file system operations, but that's left as an exercise for later. For now the set of errors is a very limited set that closely corresponds to the previous overloaded errno values, but there is some low hanging fruite to improve it. blk_status_t (ab)uses the sparse __bitwise annotations to allow for sparse typechecking, so that we can easily catch places passing the wrong values.

vio: fix reuse of vio_dring slot vio_dring_avail() will allow use of every dring entry, but when the last entry is allocated then dr->prod == dr->cons which is indistinguishable from the ring empty condition. This causes the next allocation to reuse an entry. When this happens in sunvdc, the server side vds driver begins nack'ing the messages and ends up resetting the ldc channel. This problem does not effect sunvnet since it checks for < 2. The fix here is to just never allocate the very last dring slot so that full and empty are not the same condition. The request start path was changed to check for the ring being full a bit earlier, and to stop the blk_queue if there is no space left. The blk_queue will be restarted once the ring is only half full again. The number of ring entries was increased to 512 which matches the sunvnet and Solaris vdc drivers, and greatly reduces the frequency of hitting the ring full condition and the associated blk_queue stop/starting.

This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

For v1.0 protocol, a disk's size continues to be calculated from the geometry returned by the vdisk server. The geometry returned by the server can be less than the actual number of sectors available in the backing image/device due to the rounding in the division used to compute the geometry in the vdisk server. In v1.1 protocol a disk's actual size in sectors is returned during the handshake. Use this size when v1.1 protocol is negotiated.

This fixes the issue by doing a similar thing to the xen-blkfront driver, ensuring that the scatterlist will only ever contain a segment count <= port->ring_cookies, and each segment will be page aligned, and <= page size.

Since we have to be able to handle MD updates, having an in-tree set of data structures representing the MD objects actually makes things more painful. The MD itself is easy to parse, and we can implement the existing interfaces using direct parsing of the MD binary image. The MD is now reference counted, so accesses have to now take the form: handle = mdesc_grab(); ... operations on MD ... mdesc_release(handle); The only remaining issue are cases where code holds on to references to MD property values. mdesc_get_property() returns a direct pointer to the property value, most cases just pull in the information they need and discard the pointer, but there are few that use the pointer directly over a long lifetime. Those will be fixed up in a subsequent changeset. A preliminary handler for MD update events from domain services is there, it is rudimentry but it works and handles all of the reference counting. It does not check the generation number of the MDs, and it does not generate a "add/delete" list for notification to interesting parties about MD changes but that will be forthcoming.

[SPARC64]: Abstract out mdesc accesses for better MD update handling. Since we have to be able to handle MD updates, having an in-tree set of data structures representing the MD objects actually makes things more painful. The MD itself is easy to parse, and we can implement the existing interfaces using direct parsing of the MD binary image. The MD is now reference counted, so accesses have to now take the form: handle = mdesc_grab(); ... operations on MD ... mdesc_release(handle); The only remaining issue are cases where code holds on to references to MD property values. mdesc_get_property() returns a direct pointer to the property value, most cases just pull in the information they need and discard the pointer, but there are few that use the pointer directly over a long lifetime. Those will be fixed up in a subsequent changeset. A preliminary handler for MD update events from domain services is there, it is rudimentry but it works and handles all of the reference counting. It does not check the generation number of the MDs, and it does not generate a "add/delete" list for notification to interesting parties about MD changes but that will be forthcoming.

sunvdc: add cdrom and v1.1 protocol support Interpret the media type from v1.1 protocol to support CDROM/DVD. For v1.0 protocol, a disk's size continues to be calculated from the geometry returned by the vdisk server. The geometry returned by the server can be less than the actual number of sectors available in the backing image/device due to the rounding in the division used to compute the geometry in the vdisk server. In v1.1 protocol a disk's actual size in sectors is returned during the handshake. Use this size when v1.1 protocol is negotiated. Since this size will always be larger than the former geometry computed size, disks created under v1.0 will be forwards compatible to v1.1, but not vice versa.

treewide: setup_timer() -> timer_setup() This converts all remaining cases of the old setup_timer() API into using timer_setup(), where the callback argument is the structure already holding the struct timer_list. These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

sunvdc: prevent sunvdc panic when mpgroup disk added to guest domain Using mpgroup to define multiple paths for a virtual disk causes multiple virtual-device-port ports to be created for that virtual device. Each virtual-device-port port then gets a vdisk created for it by the Linux sunvdc driver. As mpgroup is not supported by the Linux sunvdc driver it cannot handle multiple ports for a single vdisk, leading to a kernel panic at startup. This fix prevents more than one vdisk per virtual-device-port being created until full virtual disk multipathing (mpgroup) support is implemented.

block: introduce new block status code type Currently we use nornal Linux errno values in the block layer, and while we accept any error a few have overloaded magic meanings. This patch instead introduces a new blk_status_t value that holds block layer specific status codes and explicitly explains their meaning. Helpers to convert from and to the previous special meanings are provided for now, but I suspect we want to get rid of them in the long run - those drivers that have a errno input (e.g. networking) usually get errnos that don't know about the special block layer overloads, and similarly returning them to userspace will usually return somethings that strictly speaking isn't correct for file system operations, but that's left as an exercise for later. For now the set of errors is a very limited set that closely corresponds to the previous overloaded errno values, but there is some low hanging fruite to improve it. blk_status_t (ab)uses the sparse __bitwise annotations to allow for sparse typechecking, so that we can easily catch places passing the wrong values.

If a timeout is reached, any in-progress I/O's are completed with -EIO. Signed-off-by: Dwight Engen <dwight.engen@oracle.com> Reviewed-by: Chris Hyser <chris.hyser@oracle.com> Signed-off-by: David S.

treewide: setup_timer() -> timer_setup() This converts all remaining cases of the old setup_timer() API into using timer_setup(), where the callback argument is the structure already holding the struct timer_list. These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer);

sunvdc: reconnect ldc after vds service domain restarts This change enables the sunvdc driver to reconnect and recover if a vds service domain is disconnected or bounced. By default, it will wait indefinitely for the service domain to become available again, but will honor a non-zero vdc-timout md property if one is set. If a timeout is reached, any in-progress I/O's are completed with -EIO. Signed-off-by: Dwight Engen <dwight.engen@oracle.com> Reviewed-by: Chris Hyser <chris.hyser@oracle.com> Signed-off-by: David S.
