[ Upstream commit 730538e ] Lock the wiphy in the IP address notifier as another place that should have it locked before calling into the driver. This needs a bit of attention since the notifier can be called while the wiphy is already locked, when we remove an interface. Handle this by not running the notifier in this case, and instead calling out to the driver directly. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: Sasha Levin <[email protected]>
[ Upstream commit 1474bc8 ] This might seem pretty pointless rather than changing the locking immediately, but it seems safer to run for a while with checks and the old locking scheme, and then remove the wdev lock later.

[ Upstream commit 05f1362 ] As previously reported by Alexander, whose commit 69403ba ("wifi: mac80211: sdata can be NULL during AMPDU start") I'm reverting as part of this commit, there's a race between station destruction and aggregation setup, where the aggregation setup can happen while the station is being removed and queue the work after ieee80211_sta_tear_down_BA_sessions() has already run in __sta_info_destroy_part1(), and thus the worker will run with a now freed station. In his case, this manifested in a NULL sdata pointer, but really there's no guarantee whatsoever. The real issue seems to be that it's possible at all to have a situation where this occurs - we want to stop the BA sessions when doing _part1, but we cannot be sure, and WLAN_STA_BLOCK_BA isn't necessarily effective since we don't know that the setup isn't concurrently running and already got past the check. Simply call ieee80211_sta_tear_down_BA_sessions() again in the second part of station destruction, since at that point really nothing else can hold a reference to the station any more. Also revert the sdata checks since those are just misleading at this point. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: Sasha Levin <[email protected]>
commit 6e284c5 upstream. Function kmem_dump_obj() will splat if passed a pointer to a non-slab object. So nothing calls it directly, instead calling kmem_valid_obj() first to determine whether the passed pointer to a valid slab object. This means that merging kmem_valid_obj() into kmem_dump_obj() will make the code more concise. Therefore, convert kmem_dump_obj() to work the same way as vmalloc_dump_obj(), removing the need for the kmem_dump_obj() caller to check kmem_valid_obj(). After this, there are no remaining calls to kmem_valid_obj() anymore, and it can be safely removed.

[ Upstream commit 2cbc482 ] When a structure containing an RCU callback rhp is (incorrectly) freed and reallocated after rhp is passed to call_rcu(), it is not unusual for rhp->func to be set to NULL. This defeats the debugging prints used by __call_rcu_common() in kernels built with CONFIG_DEBUG_OBJECTS_RCU_HEAD=y, which expect to identify the offending code using the identity of this function. And in kernels build without CONFIG_DEBUG_OBJECTS_RCU_HEAD=y, things are even worse, as can be seen from this splat: Unable to handle kernel NULL pointer dereference at virtual address 0 ... ... PC is at 0x0 LR is at rcu_do_batch+0x1c0/0x3b8 ... ... (rcu_do_batch) from (rcu_core+0x1d4/0x284) (rcu_core) from (__do_softirq+0x24c/0x344) (__do_softirq) from (__irq_exit_rcu+0x64/0x108) (__irq_exit_rcu) from (irq_exit+0x8/0x10) (irq_exit) from (__handle_domain_irq+0x74/0x9c) (__handle_domain_irq) from (gic_handle_irq+0x8c/0x98) (gic_handle_irq) from (__irq_svc+0x5c/0x94) (__irq_svc) from (arch_cpu_idle+0x20/0x3c) (arch_cpu_idle) from (default_idle_call+0x4c/0x78) (default_idle_call) from (do_idle+0xf8/0x150) (do_idle) from (cpu_startup_entry+0x18/0x20) (cpu_startup_entry) from (0xc01530) This commit therefore adds calls to mem_dump_obj(rhp) to output some information, for example: slab kmalloc-256 start ffff410c45019900 pointer offset 0 size 256 This provides the rough size of the memory block and the offset of the rcu_head structure, which as least provides at least a few clues to help locate the problem. If the problem is reproducible, additional slab debugging can be enabled, for example, CONFIG_DEBUG_SLAB=y, which can provide significantly more information.

[ Upstream commit 0ae9942 ] When using rcutorture as a module, there are a number of conditions that can abort the modprobe operation, for example, when attempting to run both RCU CPU stall warning tests and forward-progress tests. This can cause rcu_torture_cleanup() to be invoked on the unwind path out of rcu_rcu_torture_init(), which will mean that rcu_gp_slow_unregister() is invoked without a matching rcu_gp_slow_register(). This will cause a splat because rcu_gp_slow_unregister() is passed rcu_fwd_cb_nodelay, which does not match a NULL pointer. This commit therefore forgives a mismatch involving a NULL pointer, thus avoiding this false-positive splat. Signed-off-by: Paul E.

[ Upstream commit 9fc75c4 ] The DSI horizontal timing calculations done by the driver seem to often lead to underflows or overflows, depending on the videomode. There are two main things the current driver doesn't seem to get right: DSI HSW and HFP, and VSDly. However, even following Toshiba's documentation it seems we don't always get a working display. This patch attempts to fix the horizontal timings for DSI event mode, and on a system with a DSI->HDMI encoder, a lot of standard HDMI modes now seem to work. The work relies on Toshiba's documentation, but also quite a bit on empirical testing. This also adds timing related debug prints to make it easier to improve on this later. The DSI pulse mode has only been tested with a fixed-resolution panel, which limits the testing of different modes on DSI pulse mode. However, as the VSDly calculation also affects pulse mode, so this might cause a regression.

commit 6c3fc0b upstream. A large tx latency issue was discovered during testing when only QBV was enabled. The issue occurs because gtxoffset was not set when QBV is active, it was only set when launch time is active. The patch "igc: Correct the launchtime offset" only sets gtxoffset when the launchtime_enable field is set by the user. Enabling launchtime_enable ultimately sets the register IGC_TXQCTL_QUEUE_MODE_LAUNCHT (referred to as LaunchT in the SW user manual). Section 7.5.2.6 of the IGC i225/6 SW User Manual Rev 1.2.4 states: "The latency between transmission scheduling (launch time) and the time the packet is transmitted to the network is listed in Table 7-61." However, the patch misinterprets the phrase "launch time" in that section by assuming it specifically refers to the LaunchT register, whereas it actually denotes the generic term for when a packet is released from the internal buffer to the MAC transmit logic. This launch time, as per that section, also implicitly refers to the QBV gate open time, where a packet waits in the buffer for the QBV gate to open. Therefore, latency applies whenever QBV is in use. TSN features such as QBU and QAV reuse QBV, making the latency universal to TSN features. Discussed with i226 HW owner (Shalev, Avi) and we were in agreement that the term "launch time" used in Section 7.5.2.6 is not clear and can be easily misinterpreted. Avi will update this section to: "When TQAVCTRL.TRANSMIT_MODE = TSN, the latency between transmission scheduling and the time the packet is transmitted to the network is listed in Table 7-61." Fix this issue by using igc_tsn_is_tx_mode_in_tsn() as a condition to write to gtxoffset, aligning with the newly updated SW User Manual. Tested: 1. Enrol taprio on talker board base-time 0 cycle-time 1000000 flags 0x2 index 0 cmd S gatemask 0x1 interval1 index 0 cmd S gatemask 0x1 interval2 Note: interval1 = interval for a 64 bytes packet to go through interval2 = cycle-time - interval1 2.

commit bed2eb9 upstream. Daniel Hodges reported a kernel verifier crash when playing with sched-ext. Further investigation shows that the crash is due to invalid memory access in stacksafe(). More specifically, it is the following code: if (exact != NOT_EXACT && old->stack[spi].slot_type[i % BPF_REG_SIZE] != cur->stack[spi].slot_type[i % BPF_REG_SIZE]) return false; The 'i' iterates old->allocated_stack. If cur->allocated_stack < old->allocated_stack the out-of-bound access will happen. To fix the issue add 'i >= cur->allocated_stack' check such that if the condition is true, stacksafe() should fail. Otherwise, cur->stack[spi].slot_type[i % BPF_REG_SIZE] memory access is legal.

commit 662c3e2 upstream. A selftest is added such that without the previous patch, a crash can happen. With the previous patch, the test can run successfully. The new test is written in a way which mimics original crash case: main_prog static_prog_1 static_prog_2 where static_prog_1 has different paths to static_prog_2 and some path has stack allocated and some other path does not. A stacksafe() checking in static_prog_2() triggered the crash.

commit bf32075 upstream. The error paths in nfsd_svc() are needlessly complex and can result in a final call to svc_put() without nfsd_last_thread() being called. This results in the listening sockets not being closed properly. The per-netns setup provided by nfsd_startup_new() and removed by nfsd_shutdown_net() is needed precisely when there are running threads. So we don't need nfsd_up_before. We don't need to know if it *was* up. We only need to know if any threads are left. If none are, then we must call nfsd_shutdown_net(). But we don't need to do that explicitly as nfsd_last_thread() does that for us. So simply call nfsd_last_thread() before the last svc_put() if there are no running threads. That will always do the right thing. Also discard: pr_info("nfsd: last server has exited, flushing export cache\n"); It may not be true if an attempt to start the first server failed, and it isn't particularly helpful and it simply reports normal behaviour.

… operations() [ Upstream commit 76e98a1 ] If there is ->PreviousSessionId field in the session setup request, The session of the previous connection should be destroyed. During this, if the smb2 operation requests in the previous session are being processed, a racy issue could happen with ksmbd_destroy_file_table(). This patch sets conn->status to KSMBD_SESS_NEED_RECONNECT to block incoming operations and waits until on-going operations are complete (i.e. idle) before desctorying the previous session.

This reverts commit bc79288 ("s390/dasd: Establish DMA alignment"). Quoting the original commit: linux-next commit bf8d085 ("iomap: add support for dma aligned direct-io") changes the alignment requirement to come from the block device rather than the block size, and the default alignment requirement is 512-byte boundaries. Since DASD I/O has page alignments for IDAW/TIDAW requests, let's override this value to restore the expected behavior. I mentioned TIDAW, but that was wrong. TIDAWs have no distinct alignment requirement (per p. 15-70 of POPS SA22-7832-13): Unless otherwise specified, TIDAWs may designate a block of main storage on any boundary and length up to 4K bytes, provided the specified block does not cross a 4 K-byte boundary. IDAWs do, but the original commit neglected that while ECKD DASD are typically formatted in 4096-byte blocks, they don't HAVE to be. Formatting an ECKD volume with smaller blocks is permitted (dasdfmt -b xxx), and the problematic commit enforces alignment properties to such a device that will result in errors, such as: [test@host ~]# lsdasd -l a367 | grep blksz blksz: 512 [test@host ~]# mkfs.xfs -f /dev/disk/by-path/ccw-0.0.a367-part1 meta-data=/dev/dasdc1 isize=512 agcount=4, agsize=230075 blks = sectsz=512 attr=2, projid32bit=1 = crc=1 finobt=1, sparse=1, rmapbt=1 = reflink=1 bigtime=1 inobtcount=1 nrext64=1 data = bsize=4096 blocks=920299, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0, ftype=1 log =internal log bsize=4096 blocks=16384, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 error reading existing superblock: Invalid argument mkfs.xfs: pwrite failed: Invalid argument libxfs_bwrite: write failed on (unknown) bno 0x70565c/0x100, err=22 mkfs.xfs: Releasing dirty buffer to free list! found dirty buffer (bulk) on free list! mkfs.xfs: pwrite failed: Invalid argument ...snipped... The original commit omitted the FBA discipline for just this reason, but the formatted block size of the other disciplines was overlooked. The solution to all of this is to revert to the original behavior, such that the block size can be respected. But what of the original problem? That was manifested with a direct-io QEMU guest, where QEMU itself was changed a month or two later with commit 25474d90aa ("block: use the request length for iov alignment") such that the blamed kernel commit is unnecessary.
