Rather than just using pt_regs, it now contains the actual saved state explicitly, similar to pt_regs. By doing it this way, we provide a cleaner API for userspace (or equivalently, we avoid the need for libc to provide its own definition of sigcontext). While we're at it, move PT_FLAGS_xxx to where they are not visible from userspace. And always pass siginfo and mcontext to signal handlers, even if they claim they don't need it, since sometimes they actually try to use it anyway in practice.

The texture base address registers are in units of 256 bytes. The original CS checker treated these offsets as bytes, so the original check was wrong. I fixed the units in a patch during the 2.6.36 cycle, but this ended up breaking some existing userspace (probably due to a bug in either userspace texture allocation or the drm texture mipmap checker). So for now, until we come up with a better fix, just warn if the mipmap size it too large. This will keep existing userspace working and it should be just as safe as before when we were checking the wrong units. These are GPU MC addresses, so if they fall outside of the VRAM or GART apertures, they end up at the GPU default page, so this should be safe from a security perspective. v2: Just disable the warning. It just spams the log and there's nothing the user can do about it.

Tavis Ormandy pointed out that do_io_submit does not do proper bounds checking on the passed-in iocb array: if (unlikely(nr < 0)) return -EINVAL; if (unlikely(!access_ok(VERIFY_READ, iocbpp, (nr*sizeof(iocbpp))))) return -EFAULT; ^^^^^^^^^^^^^^^^^^ The attached patch checks for overflow, and if it is detected, the number of iocbs submitted is scaled down to a number that will fit in the long. This is an ok thing to do, as sys_io_submit is documented as returning the number of iocbs submitted, so callers should handle a return value of less than the 'nr' argument passed in.

In commit d4d67150, we reopened an old hole for a 64-bit ptracer touching a 32-bit tracee in system call entry. A %rax value set via ptrace at the entry tracing stop gets used whole as a 32-bit syscall number, while we only check the low 32 bits for validity. Fix it by truncating %rax back to 32 bits after syscall_trace_enter, in addition to testing the full 64 bits as has already been added.

由 H. Peter Anvin 提交于
On 64 bits, we always, by necessity, jump through the system call table via %rax. For 32-bit system calls, in theory the system call number is stored in %eax, and the code was testing %eax for a valid system call number. At one point we loaded the stored value back from the stack to enforce zero-extension, but that was removed in checkin d4d67150. An actual 32-bit process will not be able to introduce a non-zero-extended number, but it can happen via ptrace. Instead of re-introducing the zero-extension, test what we are actually going to use, i.e. %rax. This only adds a handful of REX prefixes to the code.

由 H. Peter Anvin 提交于
compat_alloc_user_space() expects the caller to independently call access_ok() to verify the returned area. A missing call could introduce problems on some architectures. This patch incorporates the access_ok() check into compat_alloc_user_space() and also adds a sanity check on the length. The existing compat_alloc_user_space() implementations are renamed arch_compat_alloc_user_space() and are used as part of the implementation of the new global function. This patch assumes NULL will cause __get_user()/__put_user() to either fail or access userspace on all architectures. This should be followed by checking the return value of compat_access_user_space() for NULL in the callers, at which time the access_ok() in the callers can also be removed.

Not 100% sure this is due to BKL removal, its most likely a combination of that + userspace timing changes in udev/plymouth. The drm adds the sysfs device before the driver has completed internal loading, this causes udev to make the node and plymouth to open it before we've completed loading. The proper solution is to delay the sysfs manipulation until later in loading however this causes knock on issues with sysfs connector nodes, so we can use the global mutex to serialise loading and userspace opens.

This commit fixes bogus CS rejection if it contains a sequence of the following operations: - Set the color buffer 0. track->cb[i].robj becomes non-NULL. - Render. - Set a larger zbuffer than the previously-set color buffer. - Set a larger scissor area as well. - Set the color channel mask to 0 to do depth-only rendering. - Render. --> rejected, because track->cb[i].robj remained non-NULL, therefore the conditional checking for the color channel mask and friends is not performed, and the larger scissor area causes the rejection.

One subtest of mesa/demos/gltestperf takes 9 seconds to complete, so to prevent an unnecessary gpu reset followed by a hardlock, I am increasing the interval to 10 seconds after which a GPU is considered in a locked-up state. This is on RV530. However, with a little slower GPU, we would surpass the interval easily, so this is not a good fix for gltestperf. Nevertheless, this commit also fixes hardlocks in the applications which render at speed of less than 1 frame per second, where the whole frame consists of only one command stream. The game Tiny & Big is an example. This bar is now lowered to 0.1 fps. Now the question comes down to whether we should (often unsuccessfully) reset the GPU at all? Once we have stable enough drivers, we won't have to. Has the time come already? If possible, this commit should go to stable as well.
