2020-04-29linux-user/riscv: fix up struct target_ucontext definitionLIU Zhiwei
As struct target_ucontext will be transfered to signal handler, it must keep pace with struct ucontext_t defined in Linux kernel.

into staging ppc patch queue for 2020-04-17 Here are a few late bugfixes for qemu-5.0 in the ppc target code. Unless some really nasty last minute bug shows up, I expect this to be the last ppc pull request for qemu-5.0. # gpg: Signature made Fri 17 Apr 2020 06:02:13 BST # gpg: using RSA key 75F46586AE61A66CC44E87DC6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" [full] # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" [full] # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" [full] # gpg: aka "David Gibson (kernel.org) <dwg@kernel.org>" [unknown] # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dgibson/tags/ppc-for-5.0-20200417: target/ppc: Fix mtmsr(d) L=1 variant that loses interrupts target/ppc: Fix wrong interpretation of the disposition flag. linux-user/ppc: Fix padding in mcontext_t for ppc64 Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2020-04-17linux-user/ppc: Fix padding in mcontext_t for ppc64Richard Henderson
The padding that was added in 95cda4c44ee was added to a union, and so it had no effect. This fixes misalignment errors detected by clang sanitizers for ppc64 and ppc64le. In addition, only ppc64 allocates space for VSX registers, so do not save them for ppc32. The kernel only has references to CONFIG_SPE in signal_32.c, so do not attempt to save them for ppc64.

2020-04-15linux-user: fix /proc/self/stat handlingAlex Bennée
In the original bug report long files names in Guix caused /proc/self/stat be truncated without the trailing ") " as specified in proc manpage which says: (2) comm %s The filename of the executable, in parentheses. This is visible whether or not the executable is swapped out. In the kernel this is currently done by do_task_stat calling proc_task_name() which uses a structure limited by TASK_COMM_LEN (16). Additionally it should only be reporting the executable name rather than the full path. Fix both these failings while cleaning up the code to use GString to build up the reported values. As the whole function is cleaned up also adjust the white space to the current coding style.

2020-04-07linux-user: factor out reading of /proc/self/mapsAlex Bennée
Unfortunately reading /proc/self/maps is still considered the gold standard for a process finding out about it's own memory layout. As we will want this data in other contexts soon factor out the code to read and parse the data. Rather than just blindly copying the existing sscanf based code we use a more modern glib version of the parsing code to make a more general purpose map structure.

2020-03-20linux-user/syscall: Add support for clock_gettime64/clock_settime64Alistair Francis
Add support for the clock_gettime64/clock_settime64 syscalls. If your host is 64-bit or is 32-bit with the *_time64 syscall then the timespec will correctly be a 64-bit time_t. Otherwise the host will return a 32-bit time_t which will be rounded to 64-bits. This will be incorrect after y2038.

2020-03-20linux-user: Protect more syscallsAlistair Francis
New y2038 safe 32-bit architectures (like RISC-V) don't support old syscalls with a 32-bit time_t. The kernel defines new *_time64 versions of these syscalls. Add some more #ifdefs to syscall.c in linux-user to allow us to compile without these old syscalls.

This change updates TASK_UNMAPPED_BASE (the base address for guest programs) for aarch64.

2020-03-20linux-user: do prlimit selectivelyTobias Koch
Analogous to what commit 5dfa88f7 did for setrlimit, this commit selectively ignores limits for memory-related resources in prlimit64 calls. This is to prevent too restrictive limits from causing QEMU itself to malfunction.

2020-02-28target/arm: Implement v8.4-RCPCPeter Maydell
The v8.4-RCPC extension implements some new instructions: * LDAPUR, LDAPURB, LDAPURH, LDAPRSB, LDAPRSH, LDAPRSW * STLUR, STLURB, STLURH These are all in a new subgroup of encodings that sits below the top-level "Loads and Stores" group in the Arm ARM. The STLUR* instructions have standard store-release semantics; the LDAPUR* have Load-AcquirePC semantics, but (as with LDAPR*) we choose to implement them as the slightly stronger Load-Acquire.

The v8.3-RCPC extension implements three new load instructions which provide slightly weaker consistency guarantees than the existing load-acquire operations.

2020-02-28linux-user/arm: Replace ARM_FEATURE_VFP* tests for HWCAPRichard Henderson
Use isar feature tests instead of feature bit tests. Although none of QEMUs current cpus have VFPv3 without D32, replace the large comment explaining why with one line that sets ARM_HWCAP_ARM_VFPv3D16 under the correct conditions.

2020-02-21target/arm: Add _aa32_ to isar_feature functions testing 32-bit ID registersPeter Maydell
Enforce a convention that an isar_feature function that tests a 32-bit ID register always has _aa32_ in its name, and one that tests a 64-bit ID register always has _aa64_ in its name. We already follow this except for three cases: thumb_div, arm_div and jazelle, which all need _aa32_ adding. (As noted in the comment, isar_feature_aa32_fp16_arith() is an exception in that it currently tests ID_AA64PFR0_EL1, but will switch to MVFR1 once we've properly implemented FP16 for AArch32.)
