2019-04-18qom/cpu: Simplify how CPUClass:cpu_dump_state() printsMarkus Armbruster7-9/+9
CPUClass method dump_statistics() takes an fprintf()-like callback and a FILE * to pass to it. Most callers pass fprintf() and stderr. log_cpu_state() passes fprintf() and qemu_log_file. hmp_info_registers() passes monitor_fprintf() and the current monitor cast to FILE *. monitor_fprintf() casts it right back, and is otherwise identical to monitor_printf(). The callback gets passed around a lot, which is tiresome. The type-punning around monitor_fprintf() is ugly. Drop the callback, and call qemu_fprintf() instead. Also gets rid of the type-punning, since qemu_fprintf() takes NULL instead of the current monitor cast to FILE *.

2019-04-18target: Simplify how the TARGET_cpu_list() printMarkus Armbruster1-1/+1
The various TARGET_cpu_list() take an fprintf()-like callback and a FILE * to pass to it. Their callers (vl.c's main() via list_cpus(), bsd-user/main.c's main(), linux-user/main.c's main()) all pass fprintf() and stdout. Thus, the flexibility provided by the (rather tiresome) indirection isn't actually used. Drop the callback, and call qemu_printf() instead. Calling printf() would also work, but would make the code unsuitable for monitor context without making it simpler.

2019-04-17log: Make glib logging go through QEMUChristophe Fergeau1-0/+2
This commit adds a error_init() helper which calls g_log_set_default_handler() so that glib logs (g_log, g_warning, ...) are handled similarly to other QEMU logs. This means they will get a timestamp if timestamps are enabled, and they will go through the HMP monitor if one is configured. This commit also adds a call to error_init() to the binaries installed by QEMU. Since error_init() also calls error_set_progname(), this means that *-linux-user, *-bsd-user and qemu-pr-helper messages output with error_report, info_report, ... will slightly change: they will be prefixed by the binary name. glib debug messages are enabled through G_MESSAGES_DEBUG similarly to the glib default log handler. At the moment, this change will mostly impact SPICE logging if your spice version is >= 0.14.1. With older spice versions, this is not going to work as expected, but will not have any ill effect, so this call is not conditional on the SPICE version.

System calls that return a socket address do so by writing the (possibly truncated) address into the provided buffer space, but setting the addrlen parameter to the actual size of the address. To determine how much to copy back to the target memory the emulation needs to remember the incoming value of the addrlen parameter, so that it doesn't write past the buffer limits.

2019-02-18s390x: Fix the confusing contributions-after-2012 license statementsThomas Huth1-11/+8
The license information in these files is rather confusing. The text declares LGPL first, but then says that contributions after 2012 are licensed under the GPL instead. How should the average user who just downloaded the release tarball know which part is now GPL and which is LGPL? Looking at the text of the LGPL (see COPYING.LIB in the top directory), the license clearly states how this should be done instead: "3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License." Thus let's clean up the confusing statements and use the proper GPL text only.

2019-01-11qemu/queue.h: leave head structs anonymous unless necessaryPaolo Bonzini1-1/+1
Most list head structs need not be given a name. In most cases the name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV or reverse iteration, but this does not apply to lists of other kinds, and even for QTAILQ in practice this is only rarely needed. In addition, we will soon reimplement those macros completely so that they do not need a name for the head struct. So clean up everything, not giving a name except in the rare case where it is necessary. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Linux returns success if pwrite64() or pread64() are called with a zero length NULL buffer, but QEMU was returning -TARGET_EFAULT. This is the same bug that we fixed in commit 58cfa6c2e6eb51b23cc9 for the write syscall, and long before that in 38d840e6790c29f59 for the read syscall.

2019-01-09target/ppc: move FP and VMX registers into aligned vsr register arrayMark Cave-Ayland1-12/+16
The VSX register array is a block of 64 128-bit registers where the first 32 registers consist of the existing 64-bit FP registers extended to 128-bit using new VSR registers, and the last 32 registers are the VMX 128-bit registers as show below: 64-bit 64-bit +--------------------+--------------------+ | FP0 | | VSR0 +--------------------+--------------------+ | FP1 | | VSR1 +--------------------+--------------------+ | ... | ... | ... +--------------------+--------------------+ | FP30 | | VSR30 +--------------------+--------------------+ | FP31 | | VSR31 +--------------------+--------------------+ | VMX0 | VSR32 +-----------------------------------------+ | VMX1 | VSR33 +-----------------------------------------+ | ... | ... +-----------------------------------------+ | VMX30 | VSR62 +-----------------------------------------+ | VMX31 | VSR63 +-----------------------------------------+ In order to allow for future conversion of VSX instructions to use TCG vector operations, recreate the same layout using an aligned version of the existing vsr register array. Since the old fpr and avr register arrays are removed, the existing callers must also be updated to use the correct offset in the vsr register array. This also includes switching the relevant VMState fields over to using subarrays to make sure that migration is preserved.

2018-11-15linux-user/sparc/signal.c: Remove dead codePeter Maydell1-8/+8
Coverity complains (CID 1390847) about some dead code in do_sigreturn(). This is an if (err) clause that can never be true, copied from the kernel (where __get_user returns an error). The one code path that could report an error is in the currently commented-out pseudocode for handling FPU register restoring, so move the if into that comment (and fix the broken indent in the comment in the process). (The new position for the error check is also the semantically correct one -- we should not restore the signal mask from the signal frame if we get an error here, so the check must be done before set_sigmask(), not after.)

2018-11-12linux-user: Clean up nios2 main loop signal handlingPeter Maydell1-11/+6
The nios2 main loop code's code does some odd things with gdb_handlesig() that no other target CPU does: it has some signals that are delivered to gdb and only to gdb. Stop doing this, and instead behave like all the other targets: * a trap instruction becomes a SIGTRAP * an unhandled exception type returned from cpu_exec() causes us to abort(), not to try to hand gdb a SIGILL This fixes in passing Coverity issue CID 1390853, which was a complaint that the old code failed to check the return value from gdb_handlesig().
