| * linux-user: Fix 'utimensat()' implementationFilip Bozuta2020-08-231-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implementation of syscall 'utimensat()' in 'syscall.c' uses functions target_to_host/host_to_target_timespec() to convert values of 'struct timespec' between host and target. However, the implementation doesn't check whether the conversion succeeds and thus can cause an inappropriate error or succeed unappropriately instead of setting errno EFAULT ('Bad address') which is supposed to be set in these cases. This was confirmed with the LTP test for utimensat ('testcases/utimensat') which fails for test cases when the errno EFAULT is expected. After changes from this patch, the test passes for all test cases.

| * linux-user: Add support for a group of 2038 safe syscallsFilip Bozuta2020-08-232-1/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements functionality for following time64 syscalls: *clock_getres_time64 This a year 2038 safe variant of syscall: int clock_getres(clockid_t clockid, struct timespec *res) --finding the resoultion of a specified clock-- man page: https://man7.org/linux/man-pages/man2/clock_getres.2.html *timer_gettime64 *timer_settime64 These are year 2038 safe variants of syscalls: int timer_settime(timer_t timerid, int flags, const struct itimerspec *new_value, struct itimerspec *old_value) int timer_gettime(timer_t timerid, struct itimerspec *curr_value) --arming/dissarming and fetching state of POSIX per-process timer-- man page: https://man7.org/linux/man-pages/man2/timer_settime.2.html *timerfd_gettime64 *timerfd_settime64 These are year 2038 safe variants of syscalls: int timerfd_settime(int fd, int flags, const struct itimerspec *new_value, struct itimerspec *old_value) int timerfd_gettime(int fd, struct itimerspec *curr_value) --timers that notify via file descriptor-- man page: https://man7.org/linux/man-pages/man2/timerfd_settime.2.html Implementation notes: Syscall 'clock_getres_time64' was implemented similarly to 'clock_getres()'. The only difference was that for the conversion of 'struct timespec' from host to target, function 'host_to_target_timespec64()' was used instead of 'host_to_target_timespec()'. For other syscalls, new functions 'host_to_target_itimerspec64()' and 'target_to_host_itimerspec64()' were added to convert the value of the 'struct itimerspec' from host to target and vice versa. A new type 'struct target__kernel_itimerspec' was added in 'syscall_defs.h'. This type was defined with fields which are of the already defined type 'struct target_timespec'. This new 'struct target__kernel_itimerspec' type is used in these new converting functions. These new functions were defined similarly to 'host_to_target_itimerspec()' and 'target_to_host_itimerspec()' the only difference being that 'target_to_host_timespec64()' and 'host_to_target_timespec64()' were used.

| * linux-user: Modify 'target_to_host/host_to_target_itimerspec()'Filip Bozuta2020-08-231-27/+19Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Functions 'target_to_host_itimerspec()' and 'host_to_target_itimerspec()' are used to convert values of type 'struct itimerspec' between target and host. This type has 'struct timespec' as its fields. That is the reason why this patch introduces a little modification to the converting functions to be implemented using already existing functions that convert 'struct timespec': 'target_to_host_timespec()' and 'host_to_target_timespec()'. This makes the code of 'target_to_host_itimerspec()' and 'host_to_target_itimerspec()' more clean and readable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Function "print_fdset()" in "strace.c" is used to print the file descriptor values in "print__newselect()" which prints arguments of syscall _newselect(). Until changes from this patch, this function was printing "," even after the last value of the fd_set argument. This was changed in this patch by removing this unnecessary "," after the last fd value and thus improving the estetics of the _newselect() "-strace" print. Implementation notes: The printing fix was made possible by using an existing function "get_comma()" which returns a "," or an empty string "" based on its argument (0 for "," and other for "").

| * riscv: Fix bug in setting pmpcfg CSR for RISCV64Hou Weiying2020-08-221-3/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First, sizeof(target_ulong) equals to 4 on riscv32, so this change does not change the function on riscv32. Second, sizeof(target_ulong) equals to 8 on riscv64, and 'reg_index * 8 + i' is not a legal pmp_index (we will explain later), which should be 'reg_index * 4 + i'. If the parameter reg_index equals to 2 (means that we will change the value of pmpcfg2, or the second pmpcfg on riscv64), then pmpcfg_csr_write(env, 2, val) will map write tasks to pmp_write_cfg(env, 2 * 8 + [0...7], val). However, no cfg csr is indexed by value 16 or 23 on riscv64, so we consider it as a bug. We are looking for constant (e.g., define a new constant named RISCV_WORD_SIZE) in QEMU to help others understand code better, but none was found. A possible good explanation of this literal is it is the minimum word length on riscv is 4 bytes (32 bit).

The functions were renamed with these commands and then compiler issues where manually fixed. find ./* -type f -exec sed -i \ 'N;N;N;N;N;N;N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + Some lines where then manually tweaked to pass checkpatch.
