| 2019-04-05 | syscalls: Remove start and number from syscall_set_arguments() args | Steven Rostedt (VMware) | 1 | -33/+6 | |
| After removing the start and count arguments of syscall_get_arguments() it seems reasonable to remove them from syscall_set_arguments(). Note, as of today, there are no users of syscall_set_arguments(). But we are told that there will be soon. But for now, at least make it consistent with syscall_get_arguments().

| At Linux Plumbers, Andy Lutomirski approached me and pointed out that the function call syscall_get_arguments() implemented in x86 was horribly written and not optimized for the standard case of passing in 0 and 6 for the starting index and the number of system calls to get. When looking at all the users of this function, I discovered that all instances pass in only 0 and 6 for these arguments. Instead of having this function handle different cases that are never used, simply rewrite it to return the first 6 arguments of a system call. This should help out the performance of tracing system calls by ptrace, ftrace and perf.

| 2016-01-10 | um: Add full asm/syscall.h support | Mickaël Salaün | 1 | -0/+138 | |
| Add subarchitecture-independent implementation of asm-generic/syscall.h allowing access to user system call parameters and results: * syscall_get_nr() * syscall_rollback() * syscall_get_error() * syscall_get_return_value() * syscall_set_return_value() * syscall_get_arguments() * syscall_set_arguments() * syscall_get_arch() provided by arch/x86/um/asm/syscall.h This provides the necessary syscall helpers needed by HAVE_ARCH_SECCOMP_FILTER plus syscall_get_error(). This is inspired from Meredydd Luff's patch (https://gerrit.chromium.org/gerrit/21425).
