2014-11-11seccomp: change configure to avoid arm 32 to breakEduardo Otubo
Current stable version of libseccomp (2.1.1) only supports i386 and x86_64 archs correctly. This patch limits the usage of the syscall filter for those archs and updates to the correct last version of libseccomp.

inotify_add_watch() fallocate() is needed for snapshotting. If it isn’t whitelisted $ qemu-img create -f qcow2 x.qcow 1G Formatting 'x.qcow', fmt=qcow2 size=1073741824 encryption=off cluster_size=65536 lazy_refcounts=off $ qemu-kvm -display none -monitor stdio -sandbox on x.qcow QEMU 2.1.50 monitor - type 'help' for more information (qemu) savevm foo (qemu) loadvm foo will fail, as will subsequent savevm commands on the same image. fadvise64(), inotify_init1(), inotify_add_watch() are needed by the SDL display. Without the whitelist entries, qemu-kvm -sandbox on fails immediately. In my tests fadvise64() is called 50--51 times per VM run. That number seems independent of the duration of the run. fallocate(), inotify_init1(), inotify_add_watch() are called once each. Accordingly, they are added to the whitelist at a very low priority.

2014-11-11coroutine-sigaltstack: Change jmp_buf to sigjmp_bufWillem Pinckaers
This is a simple patch to change the type of old_env from jmp_buf to sigjmp_buf. old_env is used by sigsetjmp and as such should be a sigjmp_buf. This fixes a stack_chk fail in a OSX 32bit build. Since at least on OSX sigjmp_buf is four bytes larger then a jmpbuf, resulting in an overflow in sigsetjmp. Due to variable reordering this overwrites the stack cookie.

2014-11-11linux-user: Fix up timer id handlingAlexander Graf
When creating a timer handle, we give the timer id a special magic offset of 0xcafe0000. However, we never mask that offset out of the timer id before we start using it to dereference our timer array. So we always end up aborting timer operations because the timer id is out of bounds. This was not an issue before my patch e52a99f756e ("linux-user: Simplify timerid checks on g_posix_timers range") because before we would blindly mask anything above the first 16 bits. This patch simplifies the code around timer id creation by introducing a proper target_timer_id typedef that is s32, just like Linux has it. It also changes the magic offset to a value that makes all timer ids be positive.

The file sharing module should not handle printers, so disable it. The options 'load printers' and 'printing' have been available since the beginning (May 1996, commit 0e8fd3398771da2f016d72830179507f3edda51b). Option 'disable spoolss' is available since Samba 2.0.4, commit de5f42c9d9172592779fa2504d44544e3b6b1c0d). Next, "socket address" was reported as deprecated, use a combination of "interfaces" and "bind interfaces only" instead (available since October 1997, commit 79f4fb52c1ed56fd843f81b4eb0cdd2991d4d0f4). Override cache directory to avoid writing to a global directory. Option available since Samba 3.4.0, Jan 2009, commit 19a05bf2f485023b11b41dfae3f6459847d55ef7. Set "usershare max shared=0" to prevent a global directory from being used. Option available since Samba 3.0.23, February 2006, commit 5831715049f2d460ce42299963a5defdc160891b. The last option was introduced with Samba 3.4.0, but previously "state directory" was already added which exists in Samba 3.4.0. As unknown parameters are ignored (while printing a warning), it should be safe to add another option.

2014-11-10target-xtensa: add missing window check for entryMax Filippov
Entry opcode needs to check if moving to new register frame would cause register window overflow. Entry used in function prologue never overflows because preceding windowed call* opcode writes return address to the target register window frame, causing overflow exceptions at the point of call. But when a sequence of entry opcodes is used for register window spilling there may not be a call or other opcode that would cause window check between entries and they would not raise overflow exception themselves resulting in data corruption.

2014-11-09block/vdi: Limit maximum size even futherMax Reitz
The block layer read and write functions do not like requests which are bigger than INT_MAX bytes. Since the VDI bmap is read and written in a single operation, its size is therefore limited accordingly. This reduces the maximum VDI image size supported by QEMU to half of what it currently is (down to approximately 512 TB). The VDI test 084 has to be adapted accordingly. Actually, one could clearly see that it was broken from the "Could not open 'TEST_DIR/t.IMGFMT': Invalid argument" line for an image which was supposed to work just fine.

2014-11-07mips: Ensure PC update with MTC0 single-steppingMaciej W. Rozycki
Correct the way PC is updated when single-stepping instructions, by keeping the old PC only for the BS_EXCP (exception condition) state. Some MTC0 (and possibly other) instructions switch to the BS_STOP state to terminate the current translation block, so that the state transition of the simulated CPU resulting from the CP0 operation takes effect with the following instruction. This happens with `mtc0 <reg>,c0_config' for example, typically used to set KSEG0 cacheability. While single-stepping this has a side-effect of not advancing the PC past the instruction just executed; subsequent single-step traps will stop at the same instruction repeatedly. Example: (gdb) stepi 0x80004d24 in _start () 5: x/i $pc => 0x80004d24 <_start+364>: mfc0 t1,c0_config (gdb) 0x80004d28 in _start () 5: x/i $pc => 0x80004d28 <_start+368>: li at,-8 (gdb) 0x80004d2c in _start () 5: x/i $pc => 0x80004d2c <_start+372>: and t1,t1,at (gdb) 0x80004d30 in _start () 5: x/i $pc => 0x80004d30 <_start+376>: ori t1,t1,0x3 (gdb) 0x80004d34 in _start () 5: x/i $pc => 0x80004d34 <_start+380>: mtc0 t1,c0_config (gdb) 0x80004d34 in _start () 5: x/i $pc => 0x80004d34 <_start+380>: mtc0 t1,c0_config (gdb) 0x80004d34 in _start () 5: x/i $pc => 0x80004d34 <_start+380>: mtc0 t1,c0_config (gdb) 0x80004d34 in _start () 5: x/i $pc => 0x80004d34 <_start+380>: mtc0 t1,c0_config (gdb) -- oops!

2014-11-07mips: Respect CP0.Status.CU1 for microMIPS FP branchesMaciej W. Rozycki
Make microMIPS FP branches respect CP0.Status.CU1 and trap with a Coprocessor Unusable exception if COP1 has been disabled; also trap if no FPU is present at all. Standard MIPS FP instruction encodings have a more regular structure and branches are covered with a single umbrella along other instructions. This is not the case with the microMIPS encoding, this case has to be taken care of explicitly here. Code to do so has been copied from the standard MIPS code handler for OPC_CP1, in `decode_opc'. Problems arising from this bug will generally only show up on user context switches in operating systems making use of lazy FP context switches, such as Linux. It will also more readily trigger if software FPU emulation is used, either implicitly on a non-float CPU, or forced on a hard-float CPU such as with the "nofpu" Linux kernel command line argument. The problem may have been easily missed because we have no hard-float microMIPS CPU configuration present; in fact we have no microMIPS CPU configuration of any kind present. Signed-off-by: Maciej W.

Trigger recalculating sets of file descriptors for the main loop's poll() in order to make sure a possibly removed FD 0 from the poll() file descriptor array is re-added. FD 0 is removed from the decriptor array when the console's can_read() callback returns 0.

2014-11-05s390x/sclpconsole-lm: truncate input if line is too longHeinz Graalfs
As the SCLP line mode console input length is limited by the available SCCB buffer space, it might lock up if the input does not fit into the buffer. With this patch, characters that don't fit are 'eaten' up to the next CR/LF and the input line is sent truncated to the guest.

Second, if we remove QEMU_GLIB_COMPAT_H definability in vhost-usr-test.c, then we will get below warnings: tests/vhost-user-test.c: In function 'read_guest_mem': tests/vhost-user-test.c:190: warning: passing argument 1 of 'g_mutex_lock' from incompatible pointer type tests/vhost-user-test.c:234: warning: passing argument 1 of 'g_mutex_unlock' from incompatible pointer type That's because glib-compat.h redefine the g_mutex_lock/unlock function. Those functions' arguments is CompatGMutex/CompatGCond, but vhost-user-test.c is using GMutex/GCond, which cause the type is not consistent. We can rerealize those functions of vhost-user-test.c, which need a lots of patches. Let's simply address it, and leave this file alone.
