2019-01-11avoid TABs in files that only contain a fewPaolo Bonzini
Most files that have TABs only contain a handful of them. Change them to spaces so that we don't confuse people. disas, standard-headers, linux-headers and libdecnumber are imported from other projects and probably should be exempted from the check. Outside those, after this patch the following files still contain both 8-space and TAB sequences at the beginning of the line. Many of them have a majority of TABs, or were initially committed with all tabs. bsd-user/i386/target_syscall.h bsd-user/x86_64/target_syscall.h crypto/aes.c hw/audio/fmopl.c hw/audio/fmopl.h hw/block/tc58128.c hw/display/cirrus_vga.c hw/display/xenfb.c hw/dma/etraxfs_dma.c hw/intc/sh_intc.c hw/misc/mst_fpga.c hw/net/pcnet.c hw/sh4/sh7750.c hw/timer/m48t59.c hw/timer/sh_timer.c include/crypto/aes.h include/disas/bfd.h include/hw/sh4/sh.h libdecnumber/decNumber.c linux-headers/asm-generic/unistd.h linux-headers/linux/kvm.h linux-user/alpha/target_syscall.h linux-user/arm/nwfpe/double_cpdo.c linux-user/arm/nwfpe/fpa11_cpdt.c linux-user/arm/nwfpe/fpa11_cprt.c linux-user/arm/nwfpe/fpa11.h linux-user/flat.h linux-user/flatload.c linux-user/i386/target_syscall.h linux-user/ppc/target_syscall.h linux-user/sparc/target_syscall.h linux-user/syscall.c linux-user/syscall_defs.h linux-user/x86_64/target_syscall.h slirp/cksum.c slirp/if.c slirp/ip.h slirp/ip_icmp.c slirp/ip_icmp.h slirp/ip_input.c slirp/ip_output.c slirp/mbuf.c slirp/misc.c slirp/sbuf.c slirp/socket.c slirp/socket.h slirp/tcp_input.c slirp/tcpip.h slirp/tcp_output.c slirp/tcp_subr.c slirp/tcp_timer.c slirp/tftp.c slirp/udp.c slirp/udp.h target/cris/cpu.h target/cris/mmu.c target/cris/op_helper.c target/sh4/helper.c target/sh4/op_helper.c target/sh4/translate.c tcg/sparc/tcg-target.inc.c tests/tcg/cris/check_addo.c tests/tcg/cris/check_moveq.c tests/tcg/cris/check_swap.c tests/tcg/multiarch/test-mmap.c ui/vnc-enc-hextile-template.h ui/vnc-enc-zywrle.h util/envlist.c util/readline.c The following have only TABs: bsd-user/i386/target_signal.h bsd-user/sparc64/target_signal.h bsd-user/sparc64/target_syscall.h bsd-user/sparc/target_signal.h bsd-user/sparc/target_syscall.h bsd-user/x86_64/target_signal.h crypto/desrfb.c hw/audio/intel-hda-defs.h hw/core/uboot_image.h hw/sh4/sh7750_regnames.c hw/sh4/sh7750_regs.h include/hw/cris/etraxfs_dma.h linux-user/alpha/termbits.h linux-user/arm/nwfpe/fpopcode.h linux-user/arm/nwfpe/fpsr.h linux-user/arm/syscall_nr.h linux-user/arm/target_signal.h linux-user/cris/target_signal.h linux-user/i386/target_signal.h linux-user/linux_loop.h linux-user/m68k/target_signal.h linux-user/microblaze/target_signal.h linux-user/mips64/target_signal.h linux-user/mips/target_signal.h linux-user/mips/target_syscall.h linux-user/mips/termbits.h linux-user/ppc/target_signal.h linux-user/sh4/target_signal.h linux-user/sh4/termbits.h linux-user/sparc64/target_syscall.h linux-user/sparc/target_signal.h linux-user/x86_64/target_signal.h linux-user/x86_64/termbits.h pc-bios/optionrom/optionrom.h slirp/mbuf.h slirp/misc.h slirp/sbuf.h slirp/tcp.h slirp/tcp_timer.h slirp/tcp_var.h target/i386/svm.h target/sparc/asi.h target/xtensa/core-dc232b/xtensa-modules.inc.c target/xtensa/core-dc233c/xtensa-modules.inc.c target/xtensa/core-de212/core-isa.h target/xtensa/core-de212/xtensa-modules.inc.c target/xtensa/core-fsf/xtensa-modules.inc.c target/xtensa/core-sample_controller/core-isa.h target/xtensa/core-sample_controller/xtensa-modules.inc.c target/xtensa/core-test_kc705_be/core-isa.h target/xtensa/core-test_kc705_be/xtensa-modules.inc.c tests/tcg/cris/check_abs.c tests/tcg/cris/check_addc.c tests/tcg/cris/check_addcm.c tests/tcg/cris/check_addoq.c tests/tcg/cris/check_bound.c tests/tcg/cris/check_ftag.c tests/tcg/cris/check_int64.c tests/tcg/cris/check_lz.c tests/tcg/cris/check_openpf5.c tests/tcg/cris/check_sigalrm.c tests/tcg/cris/crisutils.h tests/tcg/cris/sys.c tests/tcg/i386/test-i386-ssse3.c ui/vgafont.h Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Message-Id: <20181213223737.11793-3-pbonzini@redhat.com> Reviewed-by: Aleksandar Markovic <amarkovic@wavecomp.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Wainer dos Santos Moschetta <wainersm@redhat.com> Acked-by: Richard Henderson <richard.henderson@linaro.org> Acked-by: Eric Blake <eblake@redhat.com> Acked-by: David Gibson <david@gibson.dropbear.id.au> Reviewed-by: Stefan Markovic <smarkovic@wavecomp.com> Reviewed-by: Michael S.

Add ability to target platforms to individually include user-mode support for system calls from "stat" group of system calls. This change is related to new nanoMIPS platform in the sense that it supports a different set of "stat" system calls than any other target. nanoMIPS does not support structures stat and stat64 at all. Also, support for certain number of other system calls is dropped in nanoMIPS (those are most of the time obsoleted system calls). Without this patch, build for nanoMIPS would fail.

2017-05-29linux-user: add strace support for uinfo structure of rt_sigqueueinfo() and ↵Miloš Stojanović
rt_tgsigqueueinfo() This commit adds support for printing the content of the target_siginfo_t structure in a similar way to how it is printed by the host strace. The pointer to this structure is sent as the last argument of the rt_sigqueueinfo() and rt_tgsigqueueinfo() system calls. For this purpose, print_siginfo() is used and the get_target_siginfo() function is implemented in order to get the information obtained from the pointer into the form that print_siginfo() expects. The get_target_siginfo() function is based on host_to_target_siginfo_noswap() in linux-user mode, but here both arguments are pointers to target_siginfo_t, so instead of converting the information to siginfo_t it just extracts and copies it to a target_siginfo_t structure. Prior to this commit, typical strace output used to look like this: 8307 rt_sigqueueinfo(8307,50,0x00000040007ff6b0) = 0 After this commit, it looks like this: 8307 rt_sigqueueinfo(8307,50,{si_signo=50, si_code=SI_QUEUE, si_pid=8307, si_uid=1000, si_sigval=17716762128}) = 0 Signed-off-by: Miloš Stojanović <Milos.Stojanovic@rt-rk.com> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>

2016-10-21linux-user: Fix syslog() syscall supportAleksandar Markovic
There are currently several problems related to syslog() support. For example, if the second argument "bufp" of target syslog() syscall is NULL, the current implementation always returns error code EFAULT. However, NULL is a perfectly valid value for the second argument for many use cases of this syscall. This is, for example, visible from this excerpt of man page for syslog(2): > EINVAL Bad arguments (e.g., bad type; or for type 2, 3, or 4, buf is > NULL, or len is less than zero; or for type 8, the level is > outside the range 1 to 8). Moreover, the argument "bufp" is ignored for all cases of values of the first argument, except 2, 3 and 4. This means that for such cases (the first argument is not 2, 3 or 4), there is no need to pass "buf" between host and target, and it can be set to NULL while calling host's syslog(), without loss of emulation accuracy. Note also that if "bufp" is NULL and the first argument is 2, 3 or 4, the correct returned error code is EINVAL, not EFAULT. All these details are reflected in this patch. "#ifdef TARGET_NR_syslog" is also proprerly inserted when needed. Support for Qemu's "-strace" switch for syslog() syscall is included too. LTP tests syslog11 and syslog12 pass with this patch (while fail without it), on any platform. Changes to original patch by Riku Voipio: fixed error paths in TARGET_SYSLOG_ACTION_READ_ALL to match http://lxr.free-electrons.com/source/kernel/printk/printk.c?v=4.7#L1335 Should fix also the build error in: https://lists.gnu.org/archive/html/qemu-devel/2016-10/msg03721.html Signed-off-by: Aleksandar Markovic <aleksandar.markovic@imgtec.com> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
2016-10-21linux-user: Fix socketcall() syscall supportAleksandar Markovic
Since not all Linux host platforms support socketcall() (most notably Intel), do_socketcall() function in Qemu's syscalls.c is implemented to mirror the corespondant implementation of socketcall() in Linux kernel, and to utilise individual socket operations that are supported on all Linux platforms. (see kernel source file net/socket.c, definition of socketcall). However, error codes produced by Qemu implementation are wrong for the cases of invalid values of the first argument. Also, naming of constants is not consistent with kernel one, and not consistant with Qemu convention of prefixing such constants with "TARGET_". This patch in that light brings do_socketcall() closer to its kernel counterpart, and in that way fixes the errors and yields more consisrtent Qemu code. There were also three missing cases (among 20) for strace support for socketcall(). The array that contains pointers for appropriate printing functions is updated with 3 elements, however pointers to functions are left NULL, and its implementation is left for future. Also, this patch fixes failure of LTP test socketcall02, if executed on some Qemu emulated sywstems (uer mode).

2016-10-21linux-user: Add support for adjtimex() syscallAleksandar Markovic
This patch implements Qemu user mode adjtimex() syscall support. Syscall adjtimex() reads and optionally sets parameters for a clock adjustment algorithm used in network synchonization or similar scenarios. Its declaration is: int adjtimex(struct timex *buf); The correspondent source code in the Linux kernel is at kernel/time.c, line 206. The Qemu implementation is based on invocation of host's adjtimex(), and its key part is in the "TARGET_NR_adjtimex" case segment of the the main switch statement of the function do_syscall(), in linux-user/syscalls.c. All necessary conversions of the data structures from target to host and from host to target are covered. Two new functions, target_to_host_timex() and host_to_target_timex(), are provided for the purpose of such conversions. For that purpose, the support for related structure "timex" had tp be added to the file linux-user/syscall_defs.h, based on its definition in Linux kernel. Also, the relevant support for "-strace" Qemu option is included in files linux-user/strace.c and linux-user/strace.list. This patch also fixes failures of LTP tests adjtimex01 and adjtimex02, if executed in Qemu user mode.
