reverting "l2tp: fix missing print session offset info"

by Guillaume Nault

Hi, Commit 820da5357572 ("l2tp: fix missing print session offset info") has been backported to several -stable trees (AFAICS 3.18, 4.4, 4.9, 4.14 and 4.15). This patch has been reverted upstream as the L2TP offset option was dropped. Therefore it doesn't make sense to start exporting this data in stable releases. Can you guys revert the corresponding commits from your trees, or queue up de3b58bc359a ("l2tp: revert "l2tp: fix missing print session offset info"")? If some of you have 820da5357572 queued up for other trees, then please drop it. Guillaume

[PATCH] spi: spi-s3c64xx: Fix system resume support

by Marek Szyprowski

Since Linux v4.10 release (commit 1d9174fbc55e "PM / Runtime: Defer resuming of the device in pm_runtime_force_resume()"), pm_runtime_force_resume() function doesn't runtime resume device if it was not runtime active before system suspend. Thus, driver should not do any register access after pm_runtime_force_resume() without checking the runtime status of the device. To fix this issue, simply move s3c64xx_spi_hwinit() call to s3c64xx_spi_runtime_resume() to ensure that hardware is always properly initialized. This fixes Synchronous external abort issue on system suspend/resume cycle on newer Exynos SoCs.

[PATCH ghak82] audit: Fix extended comparison of GID/EGID

by Ondrej Mosnacek

The audit_filter_rules() function in auditsc.c used the in_[e]group_p() functions to check GID/EGID match, but these functions use the current task's credentials, while the comparison should use the credentials of the task given to audit_filter_rules() as a parameter (tsk). Note that we can use group_search(cred->group_info, ...) as a replacement for both in_group_p and in_egroup_p as these functions only compare the parameter to cred->fsgid/egid and then call group_search. In fact, the usage of in_group_p was incorrect also because it compared to cred->fsgid and not cred->gid.

[PATCH v2] mtd: rawnand: Do not check FAIL bit when executing a SET_FEATURES op

by Boris Brezillon

The ONFI spec clearly says that FAIL bit is only valid for PROGRAM, ERASE and READ-with-on-die-ECC operations, and should be ignored otherwise. It seems that checking it after sending a SET_FEATURES is a bad idea because a previous READ, PROGRAM or ERASE op may have failed, and depending on the implementation, the FAIL bit is not cleared until a new READ, PROGRAM or ERASE is started. This leads to ->set_features() returning -EIO while it actually worked, which can sometimes stop a batch of READ/PROGRAM ops. Note that we only fix the ->exec_op() path here, because some drivers are abusing the NAND_STATUS_FAIL flag in their ->waitfunc() implementation to propagate other kind of errors, like wait-ready-timeout or controller-related errors. Let's not try to fix those drivers since they worked fine so far. Fixes: 8878b126df76 ("mtd: nand: add ->exec_op() implementation") Cc: stable(a)vger.kernel.org Signed-off-by: Boris Brezillon <boris.brezillon(a)bootlin.com> --- This patch is fixing a problem we had with on-die ECC on Micron NANDs [1]. On these chips, when you have an ECC failure, the FAIL bit is set and it's not cleared until the next READ operation, which led the following SET_FEATURES (used to re-enable on-die ECC) to fail with -EIO and stopped the batch of page reads started by UBIFS, which in turn led to unmountable FS.

Hello Greg, After running LTP with Fuego on the LTS kernel 4.4.y, there were a few test cases failing that I thought needed some investigation. I reviewed the first one (fcntl35 and fcntl35_64) so far. According to the comments on LTP's fcntl35.c file (by Xiao Yang <yangx.jy(a)cn.fujitsu.com>) the bug tested by this test case was fixed by: pipe: cap initial pipe capacity according to pipe-max-size commit 086e774a57fba4695f14383c0818994c0b31da7c Author: Michael Kerrisk (man-pages) <mtk.manpages(a)gmail.com> Date: Tue Oct 11 13:53:43 2016 -0700 I backported that patch (see next e-mail), tested again and confirmed that the patch fixed the bug (or at least the error message in LTP's test). Before: fcntl35.c:98: FAIL: an unprivileged user init the capacity of a pipe to 65536 unexpectedly, expected 4096 After: fcntl35.c:101: PASS: an unprivileged user init the capacity of a pipe to 4096 successfully Thanks, Daniel Sangorrin

[PATCH] xen-swiotlb: fix the check condition for xen_swiotlb_free_coherent

by Joe Jin

When run raidconfig from Dom0 we found that the Xen DMA heap is reduced, but Dom Heap is increased by the same size. Tracing raidconfig we found that the related ioctl() in megaraid_sas will call dma_alloc_coherent() to apply memory. If the memory allocated by Dom0 is not in the DMA area, it will exchange memory with Xen to meet the requiment. Later drivers call dma_free_coherent() to free the memory, on xen_swiotlb_free_coherent() the check condition (dev_addr + size - 1 <= dma_mask) is always false, it prevents calling xen_destroy_contiguous_region() to return the memory to the Xen DMA heap. This issue introduced by commit 6810df88dcfc2 "xen-swiotlb: When doing coherent alloc/dealloc check before swizzling the MFNs.".
