2016-09-15Remove remainders of HPPA backendThomas Huth
The HPPA backend has been removed by the following commit: 802b5081233a6b643a8b135a5facaf14bafaa77d tcg-hppa: Remove tcg backend But some small pieces of the HPPA backend still survived until today. Since we also do not have support for a HPPA target in QEMU, we can nowadays safely remove the remaining HPPA parts (like the disassembler code, or the detection of HPPA in the configure script).

2016-06-08linux-user: Correct signedness of target_flock l_start and l_len fieldsPeter Maydell
The l_start and l_len fields in the various target_flock structures are supposed to be '__kernel_off_t' or '__kernel_loff_t', which means they should be signed, not unsigned. Correcting the structure definitions means that __get_user() and __put_user() will correctly sign extend them if the guest is using 32 bit offsets and the host is using 64 bit offsets. This fixes failures in the LTP 'fcntl14' tests where it checks that negative seek offsets work correctly. We reindent the structures to drop hard tabs since we're touching 40% of the fields anyway.

2016-06-07linux-user: Use both si_code and si_signo when converting siginfo_tPeter Maydell
The siginfo_t struct includes a union. The correct way to identify which fields of the union are relevant is complicated, because we have to use a combination of the si_code and si_signo to figure out which of the union's members are valid. (Within the host kernel it is always possible to tell, but the kernel carefully avoids giving userspace the high 16 bits of si_code, so we don't have the information to do this the easy way...) We therefore make our best guess, bearing in mind that a guest can spoof most of the si_codes via rt_sigqueueinfo() if it likes. Once we have made our guess, we record it in the top 16 bits of the si_code, so that tswap_siginfo() later can use it. tswap_siginfo() then strips these top bits out before writing si_code to the guest (sign-extending the lower bits). This fixes a bug where fields were sometimes wrong; in particular the LTP kill10 test went into an infinite loop because its signal handler got a si_pid value of 0 rather than the pid of the sending process. As part of this change, we switch to using __put_user() in the tswap_siginfo code which writes out the byteswapped values to the target memory, in case the target memory pointer is not sufficiently aligned for the host CPU's requirements.

2016-01-08linux-user: correctly align target_epoll_eventLaurent Vivier
According to comments in /usr/include/linux/eventpoll.h, poll_event is packed only on x86_64. And to be sure fields are correctly aligned in epoll_data, use abi_XXX types for all of them. Moreover, fd type is wrong: fd is int, not ulong. This has been tested with a ppc guest on an x86_64 host: without this patch, systemd crashes (core).

2015-09-28linux-user: fix cmsg conversion in case of multiple headersJonathan Neuschäfer
Currently, __target_cmsg_nxthdr compares a pointer derived from target_cmsg against the msg_control field of target_msgh (through subtraction). This failed for me when emulating i386 code under x86_64, because pointers in the host address space and pointers in the guest address space were not the same. This patch passes the initial value of target_cmsg into __target_cmsg_nxthdr. I found and fixed two more related bugs: - __target_cmsg_nxthdr now returns the new cmsg pointer instead of the old one. - tgt_space (in host_to_target_cmsg) doesn't count "sizeof (struct target_cmsghdr)" twice anymore.

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.
