* linux-user: fix gcc-4.9 compiler error on __{get,put]}_userRiku Voipio2014-06-171-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | gcc-4.9 finds unused operand: linux-user/syscall.c: In function ‘host_to_target_stat64’: linux-user/qemu.h:301:19: error: right-hand operand of comma expression has no effect [-Werror=unused-value] ((hptr), (x)), 0) Just removing the rh operand is no good, it will error in later: linux-user/main.c: In function ‘arm_kernel_cmpxchg64_helper’: linux-user/qemu.h:330:15: error: void value not ignored as it ought to be __ret = __put_user((x), __hptr); \ Thus, remove setting __ret from __get_user and __put_user, as and set the right hand operand to (void)0 to make it clear that these return never nothing. This commit depends on the signal.c cleanup, to ensure bisectable version history.

* linux-user: Don't allow guest to block SIGSEGVPeter Maydell2014-03-171-0/+1
| | | | | | | | | | | | | | | | | | | | | Don't allow the linux-user guest to block SIGSEGV -- QEMU needs this signal to detect accesses to pages which it has marked read-only because it has cached translated code from them. We implement this by making the do_sigprocmask() wrapper suppress SIGSEGV when doing the host process signal mask manipulation; instead we store the current state of SIGSEGV in the TaskState struct. If we get a SIGSEGV for the guest when the guest has blocked the signal, we treat it as if the default SEGV handler was in place, as the kernel does for forced SIGSEGV delivery. This patch is based on an idea by Alex Barcelo, but rather than simply lying to the guest about the SIGSEGV state we track it.

* linux-user: Allow targets to specify a minimum uname releasePeter Maydell2013-09-101-0/+1
| | | | | | | | | | | | | | | | For newer target architectures, glibc can be picky about the kernel version: for example, it will not run on an aarch64 system unless the kernel reports itself as at least 3.8.0. Accommodate this by enhancing the existing support for faking the kernel version so that each target can optionally specify a minimum version: if the user doesn't force a specific fake version then we will override with the minimum required version only if the real host kernel version is insufficient. Use this facility to let aarch64 report a minimum of 3.8.0. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1378235544-22290-21-git-send-email-peter.maydell@linaro.org

* configure: Make NPTL non-optionalPeter Maydell2013-07-221-10/+0
| | | | | | | | | | | | | | | | | | | | Now all linux-user targets support building with NPTL, we can make it mandatory. This is a good idea because: * NPTL is no longer new and experimental; it is completely standard * in practice, linux-user without NPTL is nearly useless for binaries built against non-ancient glibc * it allows us to delete the rather untested code for handling the non-NPTL configuration Note that this patch leaves the CONFIG_USE_NPTL ifdefs in the bsd-user codebase alone. This makes no change for bsd-user, since our configure test for NPTL had a "#include <linux/futex.h>" which means bsd-user would never have been compiled with CONFIG_USE_NPTL defined, and it still is not.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Running programs that create large numbers of threads, such as this snippet from libstdc++'s pthread7-rope.cc: const int max_thread_count = 4; const int max_loop_count = 10000; ... for (int j = 0; j < max_loop_count; j++) { ... for (int i = 0; i < max_thread_count; i++) pthread_create (&tid[i], NULL, thread_main, 0); for (int i = 0; i < max_thread_count; i++) pthread_join (tid[i], NULL); } in user-mode emulation will quickly run out of memory. This is caused by a failure to free memory in do_syscall prior to thread exit: /* TODO: Free CPU state. */ pthread_exit(NULL); The first step in fixing this is to make all TaskStates used by QEMU dynamically allocated. The TaskState used by the initial thread was not, as it was allocated on main's stack. So fix that, free the cpu_env, free the TaskState, and we're home free, right? Not exactly. When we create a thread, we do: ts = qemu_mallocz(sizeof(TaskState) + NEW_STACK_SIZE); ... new_stack = ts->stack; ... ret = pthread_attr_setstack(&attr, new_stack, NEW_STACK_SIZE); If we blindly free the TaskState, then, we yank the current (host) thread's stack out from underneath it while it still has things to do, like calling pthread_exit. That causes problems, as you might expect. The solution adopted here is to let the C library allocate the thread's stack (so the C library can properly clean it up at pthread_exit) and provide a hint that we want NEW_STACK_SIZE bytes of stack. With those two changes, we're done, right? Well, almost. You see, we're creating all these host threads and their parent threads never bother to check that their children are finished. There's no good place for the parent threads to do so. Therefore, we need to create the threads in a detached state so the parent thread doesn't have to call pthread_join on the child to release the child's resources; the child does so automatically. With those three major changes, we can comfortably run programs like the above without exhausting memory. We do need to delete 'stack' from the TaskState structure.

At least on two Linux distributions, this is set to 8MB and 10MB respectively. If the system does not limit the stack, then we're no worse off than before.

Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896, f40d753718c72693c5f520f0d9899f6e50395e94, 96555a96d724016e13190b28cffa3bc929ac60dc and 3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file. Revert the previous hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
