Previously this had to be done with a system call to write to MSRs. The main use case is fast user space threading and switching the fs/gs registers quickly there. Another use case is having (relatively) cheap access to a new address register per thread. The instructions are opt-in and have to be explicitely enabled by the OS. Previously Linux couldn't support this because the paranoid entry code relied on the gs base never being negative outside the kernel to decide when to use swaps. It would check the gs MSR value and assume it was already running in kernel if the value was already negative. To make this work we have to revamp the paranoid exception path to not rely on this. We can use the new instructions to get (relatively) quick access to the values. This is also significantly faster than a MSR read, so will speed NMIs (critical for profiling) The original patch compared the gs with the kernel gs and assumed that if it was the same swapgs is not needed (and no user space processing was needed). This was nice and simple and didn't need a lot of changes. But this had the side effect that if a user process set its GS to the same as the kernel it may lose rescheduling checks (so a racing reschedule IPI would have been only acted upon the next non paranoid interrupt) This version now switches to full save/restore of the GS. This requires quite some changes in the paranoid path. Unfortunately didn't come up with a simpler scheme: The kernel gs for the paranoid path is now stored at the bottom of the IST stack (so that it can be derived from RSP). For this we need to know the size of the IST stack (4K or 8K), which is now passed in as a stack parameter to save_paranoid. Previously we had a flag in EBX that indicated whether SWAPGS needs to be called later or not. In the new scheme this turns into a tristate, with a new "restore from R15" mode. The exit paths are all adjusted to handle this correctly. There is one complication: to allow debuggers (especially from the int3 or debug vectors) access to the user GS we need to save it in the task struct. Normally the next context switch would overwrite it with the wrong value from kernel_gs, so we set new flag also in task_struct that prevents it. Also to prevent recursive interrupts clobbering this state in the task_struct this is only done for interrupts coming from ring 3. After a schedule comes back we check if the flag is still set. If it wasn't set the GS is back in the (swapped) kernel gs so we revert to the SWAPGS mode, instead of restoring GS. Then after these changes we need to also use the new instructions to save/restore fs and gs, so that the new values set by the users won't disappear. This is also significantly faster for the case when the 64bit base has to be switched (that is when GS is larger than 4GB), as we can replace the slow MSR write with a faster wr[fg]sbase execution. The instructions do not context switch the segment index, so the old invariant that fs or gs index have to be 0 for a different 64bit value to stick is still true. Previously it was enforced by arch_prctl, now the user program has to make sure it keeps the segment indexes zero. If it doesn't the changes may not stick. This is in term enables fast switching when there are enough threads that their TLS segment does not fit below 4GB, or alternatively programs that use fs as an additional base register will not get a sigificant context switch penalty. It is all done in a single patch to avoid bisect crash holes. v2: Change to save/restore GS instead of using swapgs based on the value. Large scale changes.
