2018-01-09target/sparc: remove MemoryRegionSection check code from ↵Jean-Christophe Dubois1-6/+0
sparc_cpu_get_phys_page_debug() This code is preventing the MMU debug code from displaying virtual mappings of IO devices (anything that is not located in the RAM). Before this patch, Qemu would output 0xffffffffffffffff (-1) as the physical address corresponding to an IO device virtual address. With this patch the intended physical address is displayed.

Add two special registers: MMID and DDR: - MMID is write-only and the only side effect of writing to it is output to the trace port, which is not emulated; - DDR is only accessible in debug mode, which is not emulated. Add two debug-mode-only opcodes: - rfdd and rfdo do return from the debug mode, which is not emulated. Add three internal opcodes for full MMU: - hwwdtlba and hwwitlba are the internal opcodes that write a value into autoupdate DTLB or ITLB entry. - ldpte is internal opcode that loads PTE entry that covers the most recent page fault address.

2018-01-08block/nbd: fix segmentation fault when .desc is not null-terminatedMurilo Opsfelder Araujo1-0/+1
The find_desc_by_name() from util/qemu-option.c relies on the .name not being NULL to call strcmp(). This check becomes unsafe when the list is not NULL-terminated, which is the case of nbd_runtime_opts in block/nbd.c, and can result in segmentation fault when strcmp() tries to access an invalid memory: #0 0x00007fff8c75f7d4 in __strcmp_power9 () from /lib64/libc.so.6 #1 0x00000000102d3ec8 in find_desc_by_name (desc=0x1036d6f0, name=0x28e46670 "server.path") at util/qemu-option.c:166 #2 0x00000000102d93e0 in qemu_opts_absorb_qdict (opts=0x28e47a80, qdict=0x28e469a0, errp=0x7fffec247c98) at util/qemu-option.c:1026 #3 0x000000001012a2e4 in nbd_open (bs=0x28e42290, options=0x28e469a0, flags=24578, errp=0x7fffec247d80) at block/nbd.c:406 #4 0x00000000100144e8 in bdrv_open_driver (bs=0x28e42290, drv=0x1036e070 <bdrv_nbd_unix>, node_name=0x0, options=0x28e469a0, open_flags=24578, errp=0x7fffec247f50) at block.c:1135 #5 0x0000000010015b04 in bdrv_open_common (bs=0x28e42290, file=0x0, options=0x28e469a0, errp=0x7fffec247f50) at block.c:1395 >From gdb, the desc[i].name was not NULL and resulted in strcmp() accessing an invalid memory: >>> p desc[5] $8 = { name = 0x1037f098 "R27A", type = 1561964883, help = 0xc0bbb23e <error: Cannot access memory at address 0xc0bbb23e>, def_value_str = 0x2 <error: Cannot access memory at address 0x2> } >>> p desc[6] $9 = { name = 0x103dac78 <__gcov0.do_qemu_init_bdrv_nbd_init> "\001", type = 272101528, help = 0x29ec0b754403e31f <error: Cannot access memory at address 0x29ec0b754403e31f>, def_value_str = 0x81f343b9 <error: Cannot access memory at address 0x81f343b9> } This patch fixes the segmentation fault in strcmp() by adding a NULL element at the end of nbd_runtime_opts.desc list, which is the common practice to most of other structs like runtime_opts in block/null.c. Thus, the desc[i].name != NULL check becomes safe because it will not evaluate to true when .desc list reached its end. Reported-by: R.

2018-01-08nbd/server: Optimize final chunk of sparse readEric Blake1-6/+7
If we are careful to handle 0-length read requests correctly, we can optimize our sparse read to send the NBD_REPLY_FLAG_DONE bit on our last OFFSET_DATA or OFFSET_HOLE chunk rather than needing a separate chunk.

2018-01-08nbd/server: Implement sparse reads atop structured replyEric Blake2-3/+76
The reason that NBD added structured reply in the first place was to allow for efficient reads of sparse files, by allowing the reply to include chunks to quickly communicate holes to the client without sending lots of zeroes over the wire. Time to implement this in the server; our client can already read such data. We can only skip holes insofar as the block layer can query them; and only if the client is okay with a fragmented request (if a client requests NBD_CMD_FLAG_DF and the entire read is a hole, we could technically return a single NBD_REPLY_TYPE_OFFSET_HOLE, but that's a fringe case not worth catering to here). Sadly, the control flow is a bit wonkier than I would have preferred, but it was minimally invasive to have a split in the action between a fragmented read (handled directly where we recognize NBD_CMD_READ with the right conditions, and sending multiple chunks) vs. a single read (handled at the end of nbd_trip, for both simple and structured replies, when we know there is only one thing being read). Likewise, I didn't make any effort to optimize the final chunk of a fragmented read to set the NBD_REPLY_FLAG_DONE, but unconditionally send that as a separate NBD_REPLY_TYPE_NONE.

Some cleanup, and allows SR to be moved from any addressing mode. Previous code was wrong for coldfire: coldfire also allows to use addressing mode to set SR/CCR.
