2021-11-22net: annotate accesses to dev->gso_max_segsEric Dumazet
dev->gso_max_segs is written under RTNL protection, or when the device is not yet visible, but is read locklessly. Add netif_set_gso_max_segs() helper. Add the READ_ONCE()/WRITE_ONCE() pairs, and use netif_set_gso_max_segs() where we can to better document what is going on. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2021-11-22dmaengine: Add core function and capability check for DMA_MEMCPY_SGAdrian Larumbe
This is the old DMA_SG interface that was removed in commit c678fa66341c ("dmaengine: remove DMA_SG as it is dead code in kernel"). It has been renamed to DMA_MEMCPY_SG to better match the MEMSET and MEMSET_SG naming convention. It should only be used for mem2mem copies, either main system memory or CPU-addressable device memory (like video memory on a PCI graphics card). Bringing back this interface was prompted by the need to use the Xilinx CDMA device for mem2mem SG transfers.

2021-11-20shm: extend forced shm destroy to support objects from several IPC nsesAlexander Mikhalitsyn
Currently, the exit_shm() function not designed to work properly when task->sysvshm.shm_clist holds shm objects from different IPC namespaces. This is a real pain when sysctl kernel.shm_rmid_forced = 1, because it leads to use-after-free (reproducer exists). This is an attempt to fix the problem by extending exit_shm mechanism to handle shm's destroy from several IPC ns'es. To achieve that we do several things: 1. add a namespace (non-refcounted) pointer to the struct shmid_kernel 2. during new shm object creation (newseg()/shmget syscall) we initialize this pointer by current task IPC ns 3. exit_shm() fully reworked such that it traverses over all shp's in task->sysvshm.shm_clist and gets IPC namespace not from current task as it was before but from shp's object itself, then call shm_destroy(shp, ns). Note: We need to be really careful here, because as it was said before (1), our pointer to IPC ns non-refcnt'ed. To be on the safe side we using special helper get_ipc_ns_not_zero() which allows to get IPC ns refcounter only if IPC ns not in the "state of destruction". Q/A Q: Why can we access shp->ns memory using non-refcounted pointer? A: Because shp object lifetime is always shorther than IPC namespace lifetime, so, if we get shp object from the task->sysvshm.shm_clist while holding task_lock(task) nobody can steal our namespace. Q: Does this patch change semantics of unshare/setns/clone syscalls? A: No. It's just fixes non-covered case when process may leave IPC namespace without getting task->sysvshm.shm_clist list cleaned up.

While dvb_tuner_ops already has dedicated suspend and resume callbacks, dvb_frontend_ops currently does not have them. Add those callbacks and use them for suspend and resume. If they are not set, the old behavior of calling sleep or init is used. This allows dvb_frontend drivers to handle resume differently from init, and suspend differently from sleep.

2021-11-19signal: Replace force_fatal_sig with force_exit_sig when in doubtEric W. Biederman
Recently to prevent issues with SECCOMP_RET_KILL and similar signals being changed before they are delivered SA_IMMUTABLE was added. Unfortunately this broke debuggers[1][2] which reasonably expect to be able to trap synchronous SIGTRAP and SIGSEGV even when the target process is not configured to handle those signals. Add force_exit_sig and use it instead of force_fatal_sig where historically the code has directly called do_exit. This has the implementation benefits of going through the signal exit path (including generating core dumps) without the danger of allowing userspace to ignore or change these signals. This avoids userspace regressions as older kernels exited with do_exit which debuggers also can not intercept. In the future is should be possible to improve the quality of implementation of the kernel by changing some of these force_exit_sig calls to force_fatal_sig. That can be done where it matters on a case-by-case basis with careful analysis.

2021-11-18mm: Add functions to zero portions of a folioMatthew Wilcox (Oracle)
These functions are wrappers around zero_user_segments(), which means that zero_user_segments() can now be called for compound pages even when CONFIG_TRANSPARENT_HUGEPAGE is disabled. Use 'xend' as the name of the parameter to indicate that this is an excluded end, not the more usual included end. Excluding the end makes more sense to the callers, but can cause confusion to readers who are more used to seeing included ends.

2021-11-18PCI: Add PCI_ERROR_RESPONSE and related definitionsNaveen Naidu
A config or MMIO read from a PCI device that doesn't exist or doesn't respond causes a PCI error. There's no real data to return to satisfy the CPU read, so most hardware fabricates ~0 data. Add a PCI_ERROR_RESPONSE definition for that and use it where appropriate to make these checks consistent and easier to find. Also add helper definitions PCI_SET_ERROR_RESPONSE() and PCI_POSSIBLE_ERROR() to make the code more readable.

2021-11-18net: dsa: felix: restrict psfp rules on ingress portXiaoliang Yang
PSFP rules take effect on the streams from any port of VSC9959 switch. This patch use ingress port to limit the rule only active on this port. Each stream can only match two ingress source ports in VSC9959. Streams from lowest port gets the configuration of SFID pointed by MAC Table lookup and streams from highest port gets the configuration of (SFID+1) pointed by MAC Table lookup. This patch defines the PSFP rule on highest port as dummy rule, which means that it does not modify the MAC table. Signed-off-by: Xiaoliang Yang <xiaoliang.yang_1@nxp.com> Signed-off-by: David S.

VSC9959 supports Per-Stream Filtering and Policing(PSFP) that complies with the IEEE 802.1Qci standard. The stream is identified by Null stream identification(DMAC and VLAN ID) defined in IEEE802.1CB. For PSFP, four tables need to be set up: stream table, stream filter table, stream gate table, and flow meter table. Identify the stream by parsing the tc flower keys and add it to the stream table. The stream filter table is automatically maintained, and its index is determined by SGID(flow gate index) and FMID(flow meter index).
