[PATCH v2] clk: s2mps11: Fix matching when built as module and DT node contains compatible

by Krzysztof Kozlowski

When driver is built as module and DT node contains clocks compatible (e.g. "samsung,s2mps11-clk"), the module will not be autoloaded because module aliases won't match. The modalias from uevent: of:NclocksT<NULL>Csamsung,s2mps11-clk The modalias from driver: platform:s2mps11-clk The devices are instantiated by parent's MFD. However both Device Tree bindings and parent define the compatible for clocks devices. In case of module matching this DT compatible will be used. The issue will not happen if this is a built-in (no need for module matching) or when clocks DT node does not contain compatible (not correct from bindings perspective but working for driver). Note when backporting to stable kernels: adjust the list of device ID entries. Cc: <stable(a)vger.kernel.org> Fixes: 53c31b3437a6 ("mfd: sec-core: Add of_compatible strings for clock MFD cells") Signed-off-by: Krzysztof Kozlowski <krzk(a)kernel.org> Acked-by: Stephen Boyd <sboyd(a)kernel.org> --- Changes since v1: 1.

So, the overcommit logic should treat it as free. Otherwise, it's possible to cause random system-wide memory allocation failures by consuming a significant amount of memory by indirectly reclaimable memory, e.g. dentry external names. If overcommit policy GUESS is used, it might be used for denial of service attack under some conditions. The following program illustrates the approach. It causes the kernel to allocate an unreclaimable kmalloc-256 chunk for each stat() call, so that at some point the overcommit logic may start blocking large allocation system-wide. int main() { char buf[256]; unsigned long i; struct stat statbuf; buf[0] = '/'; for (i = 1; i < sizeof(buf); i++) buf[i] = '_'; for (i = 0; 1; i++) { sprintf(&buf[248], "%8lu", i); stat(buf, &statbuf); } return 0; } This patch in combination with related indirectly reclaimable memory patches closes this issue.

[PATCH] usb: dwc3: gadget: Properly check last unaligned/zero chain TRB

by Thinh Nguyen

Current check for the last extra TRB for zero and unaligned transfers does not account for isoc OUT. The last TRB of the Buffer Descriptor for isoc OUT transfers will be retired with HWO=0. As a result, we won't return early. The req->remaining will be updated to include the BUFSIZ count of the extra TRB, and the actual number of transferred bytes calculation will be wrong. To fix this, check whether it's a short or zero packet and the last TRB chain bit to return early.
