2011-06-21m68k-semi.c: Use correct check for failure of do_brk()Peter Maydell
In the m68k semihosting implementation of HOSTED_INIT_SIM, use the correct check for whether do_brk() has failed -- it does not return -1 but the previous value of the break limit. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Riku Voipio <riku.voipio@iki.fi>

2011-06-21linux-user: Don't use MAP_FIXED in do_brk()Peter Maydell
Since mmap() with MAP_FIXED will map over the top of existing mappings, it's a bad idea to use it to implement brk(), because brk() with a large size is likely to overwrite important things like qemu itself or the host libc. So we drop MAP_FIXED and handle "mapped but at different address" as an error case instead. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Riku Voipio <riku.voipio@iki.fi>
2011-06-21linux-user: Handle images where lowest vaddr is not page alignedPeter Maydell
Fix a bug in the linux-user ELF loader code where it was not correctly handling images where the lowest vaddr to be loaded was not page aligned. The problem was that the code to probe for a suitable guest base address was changing the 'loaddr' variable (by rounding it to a page boundary), which meant that the load bias would then be incorrectly calculated unless loaddr happened to already be page-aligned. Binaries generated by gcc with the default linker script do start with a loadable segment at a page-aligned vaddr, so were unaffected. This bug was noticed with a binary created by the Google Go toolchain for ARM. We fix the bug by refactoring the "probe for guest base" code out into its own self-contained function.

2011-06-21linux-user: Fix the load of ELF files that have no "useful" symbolCédric VINCENT
This patch fixes a "double free()" due to "realloc(syms, 0)" in the loader when the ELF file has no "useful" symbol, as with the following example (compiled with "sh4-linux-gcc -nostdlib"): .text .align 1 .global _start _start: mov #1, r3 trapa #40 // syscall(__NR_exit) nop The bug appears when the log (option "-d") is enabled.

2011-06-15hw/9118.c: Implement active-low interrupt supportPeter Maydell
The 9118 ethernet controller interrupt line is active low unless the IRQ config register is programmed to set both the IRQ_POL (polarity: active-high) and IRQ_TYPE (type: push-pull) bits: implement support for inverting the irq output in other configurations. This also requires that we support setting the bits in the first place, and that we correctly preserve them across software reset.

2011-06-15Introduce format string for pid_tAndreas Färber
BeOS and Haiku on i386 use long for 32-bit types, including pid_t. Using %d with pid_t therefore results in a warning. Unfortunately POSIX:2008 does not define a PRId* string for pid_t. In some places pid_t was previously casted to long and %ld hardcoded. The predecessor of this patch added another upcast for the simpletrace filename but was not applied to date. Since new uses of pid_t with %d keep creeping in, let's instead define an OS-dependent format string and use that consistently.

2011-06-15Allow nested qemu_bh_poll() after BH deletionKevin Wolf
Without this, qemu segfaults when a BH handler first deletes its BH and then calls another function which involves a nested qemu_bh_poll() call. This can be reproduced by generating an I/O error (e.g. with blkdebug) on an IDE device and using rerror/werror=stop to stop the VM. When continuing the VM, qemu segfaults.

2011-06-15ide: Clear error_status after restarting flushKevin Wolf

2011-06-15ide: Split error status from status registerKevin Wolf
When adding the werror=stop mode, some flags were added to s->status which are used to determine what kind of operation should be restarted when the VM is continued. Unfortunately, it turns out that s->status is in fact a device register and as such is visible to the guest (some of the abused bits are even writable for the guest). For migration we keep on using the old VMState field (renamed to migration_compat_status) if the status register doesn't use any of the previously abused bits. If it does, we use a subsection with a clean copy of the status register. The error status is always sent in a subsection if there is any error. It can't use the old field because errors happen even without PCI. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-06-15qcow2: Fix in-flight list after qcow2_cache_put failureKevin Wolf
If qcow2_cache_put returns an error during cluster allocation and the allocation fails, it must be removed from the list of in-flight allocations. Otherwise we'd get a loop in the list when the ACB is used for the next allocation. Luckily, this qcow2_cache_put shouldn't fail anyway because the L2 table is only read, so that qcow2_cache_put doesn't even involve I/O.

2011-06-14libcacard: add libcacard.la targetAlon Levy
No flag to configure is required. Instead, added a libcacard.la target that is not built by default, only when requested explicitly via: mkdir build cd build ../configure make libcacard.la make install-libcacard Uses libtool to do actual linking of object files and shared library, and installing. Tested only under linux, but supposed to work on other systems as well. If libtool isn't found you get a message complaining about that, only at build time (since it is not a default target I did not add a message at configure time). New build artifacts: .libs subdirectories (at <buildroot> and <buildroot>/libcacard) *.lo files (at same locations as the respective o files) Added %.lo : %.c rule that uses libtool. Updated clean rule to clean up those artifacts. Added specific rule to call dtrace with libtool wrapper (note that because of a current upstream dtrace bug fixed by systemtap b1568fd85 commit the -fPIC flag isn't actually passed on. still current dtrace+libtool produced object links fine). If libtool is missing any of the following targets will complain and exit 1: any subdir: *.lo root and libcacard: libcacard.la, libcacard-instsall Tested to link and load with all tracing backends.
