[PATCH v2 05/10] x86/traps: Clear TIF_BLOCKSTEP on all debug exceptions

The SDM says that debug exceptions clear BTF, and we need to keep TIF_BLOCKSTEP in sync with BTF. Clear it unconditionally and improve the comment. I suspect that the fact that kmemcheck could cause TIF_BLOCKSTEP not to be cleared was just an oversight. Signed-off-by: Andy Lutomirski

[PATCH v2 07/10] x86/entry: Vastly simplify SYSENTER TF handling

Due to a blatant design error, SYSENTER doesn't clear TF. As a result, if a user does SYSENTER with TF set, we will single-step through the kernel until something clears TF. There is absolutely nothing we can do to prevent this short of turning off SYSENTER [1]. Simplify the handling

This makes the 32-bit code work just like the 64-bit code. It should speed up syscalls on 32-bit kernels on Skylake by something like 20 cycles (by analogy to the 64-bit compat case). It also cleans up NT just like we do for the 64-bit case. Signed-off-by: Andy Lutomirski ---

Right after SYSENTER, we can get a #DB or NMI. On x86_32, there's no IST, so the exception handler is invoked on the temporary SYSENTER stack. Because the SYSENTER stack is very small, we have a fixup to switch off the stack quickly when this happens. The old fixup had several issues: 1. It

This forth version of the API set for HW Buffer management (that was initially submitted here: http://thread.gmane.org/gmane.linux.kernel/2125152), is actually the third version done right. Now it is really possible to disable the HWBM through the kernel configuration. Since the second version I

[PATCH 00/10] x86: Various SYSENTER/SYSEXIT/#DB fixes and cleanups

hpa asked me to get rid of the ASM_CLAC at the beginning of the SYSENTER path. Little did he know... This series makes the observed behavior of SYSENTER wrt flags the same for all sane flags and kernel bitnesses. That is, SYSENTER preserves flags now unless you do a syscall that explicitly

[PATCH v2 02/10] x86/entry/compat: In SYSENTER, sink AC clearing below the existing FLAGS test

CLAC is slow, and the SYSENTER code already has an unlikely path that runs if unusual flags are set. Drop the CLAC and instead rely on the unlikely path to clear AC. This seems to save ~24 cycles on my Skylake laptop. (Hey, Intel, make this faster please!) Signed-off-by: Andy Lutomirski
