[Linux-stable-mirror] Patch "ACPI: APEI / ERST: Fix missing error handling in erst_reader()" has been added to the 4.4-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ACPI: APEI / ERST: Fix missing error handling in erst_reader() to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: acpi-apei-erst-fix-missing-error-handling-in-erst_reader.patch and it can be found in the queue-4.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From bb82e0b4a7e96494f0c1004ce50cec3d7b5fb3d1 Mon Sep 17 00:00:00 2001 From: Takashi Iwai <tiwai(a)suse.de> Date: Thu, 14 Dec 2017 13:31:16 +0100 Subject: ACPI: APEI / ERST: Fix missing error handling in erst_reader() From: Takashi Iwai <tiwai(a)suse.de> commit bb82e0b4a7e96494f0c1004ce50cec3d7b5fb3d1 upstream. The commit f6f828513290 ("pstore: pass allocated memory region back to caller") changed the check of the return value from erst_read() in erst_reader() in the following way: if (len == -ENOENT) goto skip; - else if (len < 0) { - rc = -1; + else if (len < sizeof(*rcd)) { + rc = -EIO; goto out; This introduced another bug: since the comparison with sizeof() is cast to unsigned, a negative len value doesn't hit any longer. As a result, when an error is returned from erst_read(), the code falls through, and it may eventually lead to some weird thing like memory corruption. This patch adds the negative error value check more explicitly for addressing the issue.

However, if that process was interrupted after unbind the vma, we missed a flush of the inflight GGTT writes before we made that GTT space available again for reuse, with the prospect that we would redirect them to another page.

[note, only the inat.h portion, to get objtool back in sync - gregkh] b0caa8c8c6bbc422bc3c32b64852d6d618f32b49 Mon Sep 17 00:00:00 2001 When computing a linear address and segmentation is used, we need to know the base address of the segment involved in the computation. In most of the cases, the segment base address will be zero as in USER_DS/USER32_DS. However, it may be possible that a user space program defines its own segments via a local descriptor table. In such a case, the segment base address may not be zero. Thus, the segment base address is needed to calculate correctly the linear address. If running in protected mode, the segment selector to be used when computing a linear address is determined by either any of segment override prefixes in the instruction or inferred from the registers involved in the computation of the effective address; in that order. Also, there are cases when the segment override prefixes shall be ignored (i.e., code segments are always selected by the CS segment register; string instructions always use the ES segment register when using rDI register as operand). In long mode, segment registers are ignored, except for FS and GS. In these two cases, base addresses are obtained from the respective MSRs. For clarity, this process can be split into four steps (and an equal number of functions): determine if segment prefixes overrides can be used; parse the segment override prefixes, and use them if found; if not found or cannot be used, use the default segment registers associated with the operand registers. Once the segment register to use has been identified, read its value to obtain the segment selector. The method to obtain the segment selector depends on several factors. In 32-bit builds, segment selectors are saved into a pt_regs structure when switching to kernel mode. The same is also true for virtual-8086 mode. In 64-bit builds, segmentation is mostly ignored, except when running a program in 32-bit legacy mode. In this case, CS and SS can be obtained from pt_regs. DS, ES, FS and GS can be read directly from the respective segment registers. In order to identify the segment registers, a new set of #defines is introduced. It also includes two special identifiers. One of them indicates when the default segment register associated with instruction operands shall be used. Another one indicates that the contents of the segment register shall be ignored; this identifier is used when in long mode.

Simplify the patch compared to v1 as suggested by Bjørn Mork by taking advantage of the fact that existing devices work with sendsetup = true too. Use sendsetup = true for the NMEA interface of QCSERIAL_SWI and add DEVICE_SWI entries for the EM7565 PID 0x9091 and the EM7565 QDL PID 0x9090.
