Andreas Kling	ac71775de5	Kernel: Make all syscall functions return KResultOr<T> ... This makes it a lot easier to return errors since we no longer have to worry about negating EFOO errors and can just return them flat.	2021-03-01 13:54:32 +01:00
Andreas Kling	292cd53192	Kernel: Remove SmapDisabler in sys$ioctl() ... Use copy_{to,from}_user() in the various File::ioctl() implementations instead of disabling SMAP wholesale in sys$ioctl(). This patch does not port IPv4Socket::ioctl() to those API's since that will be more involved. That function now creates a local SmapDisabler.	2020-07-31 00:17:25 +02:00
Andreas Kling	949aef4aef	Kernel: Move syscall implementations out of Process.cpp ... This is something I've been meaning to do for a long time, and here we finally go. This patch moves all sys$foo functions out of Process.cpp and into files in Kernel/Syscalls/. It's not exactly one syscall per file (although it could be, but I got a bit tired of the repetitive work here..) This makes hacking on individual syscalls a lot less painful since you don't have to rebuild nearly as much code every time. I'm also hopeful that this makes it easier to understand individual syscalls. :^)	2020-07-30 23:40:57 +02:00
