2019-03-11mips_malta: Clean up definition of flash memory size somewhatMarkus Armbruster
pflash_cfi01_register() takes a size in bytes, a block size in bytes and a number of blocks. mips_malta_init() passes BIOS_SIZE, 65536, FLASH_SIZE >> 16. Actually consistent only because BIOS_SIZE (defined in include/hw/mips/bios.h as (4 * MiB)) matches FLASH_SIZE (defined locally as 0x400000). Confusing all the same. Pass FLASH_SIZE instead of BIOS_SIZE.

2019-03-11hw/mips/malta: Restrict 'bios_size' variable scopePhilippe Mathieu-Daudé
The 'bios_size' variable is only used in the 'if (!kernel_filename && !dinfo)' clause. This is the case when we don't provide -pflash command line option, and also don't provide a -kernel option. In this case we will check for the -bios option, or use the default BIOS_FILENAME file. The 'bios' term is valid in this if statement, but is confuse in the whole mips_malta_init() scope. Restrict his scope.

2019-03-11r2d: Fix flash memory size, sector size, width, device IDMarkus Armbruster
pflash_cfi02_register() takes a size in bytes, a block size in bytes and a number of blocks. r2d_init() passes FLASH_SIZE, 16 * KiB, FLASH_SIZE >> 16. Does not compute: size doesn't match block size * number of blocks. The latter happens to win: FLASH_SIZE / 4, i.e. 8MiB. The best information we have on the physical hardware lists a Cypress S29PL127J60TFI130 128MiBit NOR flash addressable in words of 16 bits, in sectors of 4 and 32 Kibiwords. We don't model multiple sector sizes. Fix the flash size from 8 to 16MiB, and adjust the sector size from 16 to 64KiB. Fix the width from 4 to 2. While there, supply the real device IDs 0x0001, 0x227e, 0x2220, 0x2200 instead of zeros.

2019-03-11ppc405_boards: Don't size flash memory to match backing imageMarkus Armbruster
Machine "ref405ep" maps its flash memory at address 2^32 - image size. Image size is rounded up to the next multiple of 64KiB. Useless, because pflash_cfi02_realize() fails with "failed to read the initial flash content" unless the rounding is a no-op. If the image size exceeds 0x80000 Bytes, we overlap first SRAM, then other stuff. No idea how that would play out, but useful outcomes seem unlikely. Map the flash memory at fixed address 0xFFF80000 with size 512KiB, regardless of image size, to match the physical hardware. Machine "taihu" maps its boot flash memory similarly. The code even has a comment /* XXX: should check that size is 2MB */, followed by disabled code to adjust the size to 2MiB regardless of image size. Its code to map its application flash memory looks the same, except there the XXX comment asks for 32MiB, and the code to adjust the size isn't disabled. Note that pflash_cfi02_realize() fails with "failed to read the initial flash content" for images smaller than 32MiB. Map the boot flash memory at fixed address 0xFFE00000 with size 2MiB, to match the physical hardware. Delete dead code from application flash mapping, and simplify some.

2019-03-11sam460ex: Don't size flash memory to match backing imageMarkus Armbruster
Machine "sam460ex" maps its flash memory at address 0xFFF00000. When no image is supplied, its size is 1MiB (0x100000), and 512KiB of ROM get mapped on top of its second half. Else, it's the size of the image rounded up to the next multiple of 64KiB. The rounding is actually useless: pflash_cfi01_realize() fails with "failed to read the initial flash content" unless it's a no-op. I have no idea what happens when the pflash's size exceeds 1MiB. Useful outcomes seem unlikely. I guess memory at the end of the address space remains unmapped when it's smaller than 1MiB. Again, useful outcomes seem unlikely. The physical hardware appears to have 512KiB of flash memory: https://eu.mouser.com/datasheet/2/268/atmel_AT49BV040B-1180330.pdf For now, just set the flash memory size to 1MiB regardless of image size, and document the mess.

flash.h's incomplete struct pflash_t is completed both in pflash_cfi01.c and in pflash_cfi02.c. The complete types are incompatible. This can hide type errors, such as passing a pflash_t created with pflash_cfi02_register() to pflash_cfi01_get_memory(). Furthermore, POSIX reserves typedef names ending with _t.

2019-03-11chardev: add support for authorization for TLS clientsDaniel P. Berrange
Currently any client which can complete the TLS handshake is able to use a chardev server. The server admin can turn on the 'verify-peer' option for the x509 creds to require the client to provide a x509 certificate. This means the client will have to acquire a certificate from the CA before they are permitted to use the chardev server. This is still a fairly low bar. This adds a 'tls-authz=OBJECT-ID' option to the socket chardev backend which takes the ID of a previously added 'QAuthZ' object instance. This will be used to validate the client's x509 distinguished name. Clients failing the check will not be permitted to use the chardev server. For example to setup authorization that only allows connection from a client whose x509 certificate distinguished name contains 'CN=fred', you would use: $QEMU -object tls-creds-x509,id=tls0,dir=/home/berrange/qemutls,\ endpoint=server,verify-peer=yes \ -object authz-simple,id=authz0,identity=CN=laptop.example.com,,\ O=Example Org,,L=London,,ST=London,,C=GB \ -chardev socket,host=127.0.0.1,port=9000,server,\ tls-creds=tls0,tls-authz=authz0 \ ...other qemu args...

This fixes: # lm32-softmmu/qemu-system-lm32 Could not allocate dynamic translator buffer # sysctl kern.wxabort=1 kern.wxabort: 0 -> 1 # lm32-softmmu/qemu-system-lm32 mmap: Not supported Abort trap (core dumped) # gdb -q lm32-softmmu/qemu-system-lm32 qemu-system-lm32.core (gdb) bt #0 0x000017e3c156c50a in _thread_sys___syscall () at {standard input}:5 #1 0x000017e3c15e5d7a in *_libc_mmap (addr=Variable "addr" is not available.) at /usr/src/lib/libc/sys/mmap.c:47 #2 0x000017e17d9abc8b in alloc_code_gen_buffer () at /usr/src/qemu/accel/tcg/translate-all.c:1064 #3 0x000017e17d9abd04 in code_gen_alloc (tb_size=0) at /usr/src/qemu/accel/tcg/translate-all.c:1112 #4 0x000017e17d9abe81 in tcg_exec_init (tb_size=0) at /usr/src/qemu/accel/tcg/translate-all.c:1149 #5 0x000017e17d9897e9 in tcg_init (ms=0x17e45e456800) at /usr/src/qemu/accel/tcg/tcg-all.c:66 #6 0x000017e17d9891b8 in accel_init_machine (acc=0x17e3c3f50800, ms=0x17e45e456800) at /usr/src/qemu/accel/accel.c:63 #7 0x000017e17d989312 in configure_accelerator (ms=0x17e45e456800, progname=0x7f7fffff07b0 "lm32-softmmu/qemu-system-lm32") at /usr/src/qemu/accel/accel.c:111 #8 0x000017e17d9d8616 in main (argc=1, argv=0x7f7fffff06b8, envp=0x7f7fffff06c8) at vl.c:4325 [1] https://www.openbsd.org/faq/upgrade60.html [2] https://undeadly.org/cgi?action=article&sid=20160527203200 Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20190307142822.8531-3-philmd@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2019-03-11oslib-posix: Ignore fcntl("/dev/null", F_SETFL, O_NONBLOCK) failurePhilippe Mathieu-Daudé
Previous to OpenBSD 6.3 [1], fcntl(F_SETFL) is not permitted on memory devices. Trying this call sets errno to ENODEV ("not a memory device"): 19 ENODEV Operation not supported by device. An attempt was made to apply an inappropriate function to a device, for example, trying to read a write-only device such as a printer. Do not assert fcntl failures in this specific case (errno set to ENODEV) on OpenBSD. This fixes: $ lm32-softmmu/qemu-system-lm32 assertion "f != -1" failed: file "util/oslib-posix.c", line 247, function "qemu_set_nonblock" Abort trap (core dumped) [1] The fix seems https://github.com/openbsd/src/commit/c2a35b387f9d3c "fcntl(F_SETFL) invokes the FIONBIO and FIOASYNC ioctls internally, so the memory devices (/dev/null, /dev/zero, etc) need to permit them."

2019-03-11lsi: check if SIGP bit is already set in Wait reselectSven Schnelle
If SIGP is set, the 'Wait for Reselection' command should jump immediately to the address stored in the second DWORD of the instruction.

The CPUID code will call kvm_arch_get_supported_cpuid() and, even though it is undef kvm_enabled() so it never runs for user-mode emulators, sometimes clang will not optimize it out at -O0. That could be considered a compiler bug, however at -O0 we give it a pass and just add the stubs.

2019-03-11configure: Enable werror for git worktreesAlexey Kardashevskiy
The configure script checks multiple times whether it works in a git repository and it does this by "test -e "${source_path}/.git" in 4 cases but in one case where it tries to enable werror "-d" is used there which fails on git worktrees as .git is a file then and not a directory.

2019-03-11hw/i386/pc: run the multiboot loader before the PVH loaderStefano Garzarella
Some multiboot images could be in the ELF format. In the current implementation QEMU fails because we try to load these images as a PVH image. In order to fix this issue, we should try multiboot first (we already check the multiboot magic header before to load it). If it is not a multiboot image, we can try the PVH loader.
