This reverts that fix, and puts the proper fixes in place in the drivers to avoid the use-after-frees.

e1fa9ea | Andreas Gruenbacher | 11 May 2022, 16:27:12 UTC | gfs2: Stop using glock holder auto-demotion for now We're having unresolved issues with the glock holder auto-demotion mechanism introduced in commit dc732906c245. This mechanism was assumed to be essential for avoiding frequent short reads and writes until commit 296abc0d91d8 ("gfs2: No short reads or writes upon glock contention"). Since then, when the inode glock is lost, it is simply re-acquired and the operation is resumed. This means that apart from the performance penalty, we might as well drop the inode glock before faulting in pages, and re-acquire it afterwards.

fa5dfa6 | Andreas Gruenbacher | 04 May 2022, 21:37:30 UTC | gfs2: buffered write prefaulting In gfs2_file_buffered_write, to increase the likelihood that all the user memory we're trying to write will be resident in memory, carry out the write in chunks and fault in each chunk of user memory before trying to write it. Otherwise, some workloads will trigger frequent short "internal" writes, causing filesystem blocks to be allocated and then partially deallocated again when writing into holes, which is wasteful and breaks reservations. Neither the chunked writes nor any of the short "internal" writes are user visible. Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com> | 13 May 2022, 20:32:52 UTC |

Conversely, functions gfs2_file_direct_write and gfs2_file_buffered_write count the number of bytes read from the user buffer.

To compute the end of the allocation, gfs2_iomap_end() incorrectly rounded the end of the attempted write down to the next block boundary to arrive at the end of the allocation. It would have to round up, but the end of the allocation is also available as iomap->offset + iomap->length, so just use that instead. In addition, use round_up() for computing the start of the unused range.

21d1d19 | Zack Rusin | 18 March 2022, 17:43:31 UTC | drm/vmwgfx: Disable command buffers on svga3 without gbobjects With very limited vram on svga3 it's difficult to handle all the surface migrations. Without gbobjects, i.e. the ability to store surfaces in guest mobs, there's no reason to support intermediate svga2 features, especially because we can fall back to fb traces and svga3 will never support those in-between features. On svga3 we wither want to use fb traces or screen targets (i.e. gbobjects), nothing in between.

3740651 | Maxim Mikityanskiy | 12 May 2022, 09:18:30 UTC | tls: Fix context leak on tls_device_down The commit cited below claims to fix a use-after-free condition after tls_device_down. Apparently, the description wasn't fully accurate. The context stayed alive, but ctx->netdev became NULL, and the offload was torn down without a proper fallback, so a bug was present, but a different kind of bug. Due to misunderstanding of the issue, the original patch dropped the refcount_dec_and_test line for the context to avoid the alleged premature deallocation. That line has to be restored, because it matches the refcount_inc_not_zero from the same function, otherwise the contexts that survived tls_device_down are leaked. This patch fixes the described issue by restoring refcount_dec_and_test. After this change, there is no leak anymore, and the fallback to software kTLS still works.

810c2f0 | Amit Cohen | 11 May 2022, 11:57:47 UTC | mlxsw: Avoid warning during ip6gre device removal IPv6 addresses which are used for tunnels are stored in a hash table with reference counting. When a new GRE tunnel is configured, the driver is notified and configures it in hardware. Currently, any change in the tunnel is not applied in the driver. It means that if the remote address is changed, the driver is not aware of this change and the first address will be used. This behavior results in a warning [1] in scenarios such as the following: # ip link add name gre1 type ip6gre local 2000::3 remote 2000::fffe tos inherit ttl inherit # ip link set name gre1 type ip6gre local 2000::3 remote 2000::ffff ttl inherit # ip link delete gre1 The change of the address is not applied in the driver. Currently, the driver uses the remote address which is stored in the 'parms' of the overlay device. When the tunnel is removed, the new IPv6 address is used, the driver tries to release it, but as it is not aware of the change, this address is not configured and it warns about releasing non existing IPv6 address. Fix it by using the IPv6 address which is cached in the IPIP entry, this address is the last one that the driver used, so even in cases such the above, the first address will be released, without any warning.

This reordering of arguments broke BPF programs that use the raw tracepoint (e.g. tp_btf programs). The type of the second argument has changed and existing programs that assume a task_struct* argument (e.g. for bpf_task_storage access) will now fail to verify. If we instead append the new argument to the end, all existing programs would continue to work and can conditionally extract the prev_state argument on supported kernel versions.

The action potentially allows touching any skb bytes, so it may end-up modifying shared data. The above causes some sporadic MPTCP self-test failures, due to this code: tc -n $ns2 filter add dev ns2eth$i egress \ protocol ip prio 1000 \ handle 42 fw \ action pedit munge offset 148 u8 invert \ pipe csum tcp \ index 100 The above modifies a data byte outside the skb head and the skb is a cloned one, carrying a TCP output packet. This change addresses the issue by keeping track of a rough over-estimate highest skb offset accessed by the action and ensuring such offset is really writable. Note that this may cause performance regressions in some scenarios, but hopefully pedit is not in the critical path.

The loop following this code starts calling skb_add_rx_frag() starting with i=1 and thus frag[0] is never initialized. Since i is initialized to zero at the top of the primary loop, we can just reference and post-increment i instead of hardcoding the 0 when calling skb_add_rx_frag() the first time.

792ea6a | Lukas Wunner | 10 May 2022, 07:56:05 UTC | genirq: Remove WARN_ON_ONCE() in generic_handle_domain_irq() Since commit 0953fb263714 ("irq: remove handle_domain_{irq,nmi}()"), generic_handle_domain_irq() warns if called outside hardirq context, even though the function calls down to handle_irq_desc(), which warns about the same, but conditionally on handle_enforce_irqctx(). The newly added warning is a false positive if the interrupt originates from any other irqchip than x86 APIC or ARM GIC/GICv3. Those are the only ones for which handle_enforce_irqctx() returns true. Per commit c16816acd086 ("genirq: Add protection against unsafe usage of generic_handle_irq()"): "In general calling generic_handle_irq() with interrupts disabled from non interrupt context is harmless. For some interrupt controllers like the x86 trainwrecks this is outright dangerous as it might corrupt state if an interrupt affinity change is pending." Examples for interrupt chips where the warning is a false positive are USB-attached GPIO controllers such as drivers/gpio/gpio-dln2.c: USB gadgets are incapable of directly signaling an interrupt because they cannot initiate a bus transaction by themselves. All communication on the bus is initiated by the host controller, which polls a gadget's Interrupt Endpoint in regular intervals. If an interrupt is pending, that information is passed up the stack in softirq context, from which a hardirq is synthesized via generic_handle_domain_irq(). Remove the warning to eliminate such false positives.

Fixes regression in commit cbe6c3a8f8f4 ("net: atlantic: invert deep par in pm functions, preventing null derefs"), where I disabled deep pm resets in suspend and resume, trying to make sense of the atl_resume_common() deep parameter in the first place. It turns out, that atlantic always has to deep reset on pm operations. Even though I expected that and tested resume, I screwed up by kexec-rebooting into an unpatched kernel, thus missing the breakage. This fixup obsoletes the deep parameter of atl_resume_common, but I leave the cleanup for the maintainers to post to mainline. Suspend and hibernation were successfully tested by the reporters.

260364d | Mike Rapoport | 10 May 2022, 00:34:28 UTC | arm[64]/memremap: don't abuse pfn_valid() to ensure presence of linear map The semantics of pfn_valid() is to check presence of the memory map for a PFN and not whether a PFN is covered by the linear map. The memory map may be present for NOMAP memory regions, but they won't be mapped in the linear mapping. Accessing such regions via __va() when they are memremap()'ed will cause a crash. On v5.4.y the crash happens on qemu-arm with UEFI [1]: <1>[ 0.084476] 8<--- cut here --- <1>[ 0.084595] Unable to handle kernel paging request at virtual address dfb76000 <1>[ 0.084938] pgd = (ptrval) <1>[ 0.085038] [dfb76000] *pgd=5f7fe801, *pte=00000000, *ppte=00000000 ... <4>[ 0.093923] [<c0ed6ce8>] (memcpy) from [<c16a06f8>] (dmi_setup+0x60/0x418) <4>[ 0.094204] [<c16a06f8>] (dmi_setup) from [<c16a38d4>] (arm_dmi_init+0x8/0x10) <4>[ 0.094408] [<c16a38d4>] (arm_dmi_init) from [<c0302e9c>] (do_one_initcall+0x50/0x228) <4>[ 0.094619] [<c0302e9c>] (do_one_initcall) from [<c16011e4>] (kernel_init_freeable+0x15c/0x1f8) <4>[ 0.094841] [<c16011e4>] (kernel_init_freeable) from [<c0f028cc>] (kernel_init+0x8/0x10c) <4>[ 0.095057] [<c0f028cc>] (kernel_init) from [<c03010e8>] (ret_from_fork+0x14/0x2c) On kernels v5.10.y and newer the same crash won't reproduce on ARM because commit b10d6bca8720 ("arch, drivers: replace for_each_membock() with for_each_mem_range()") changed the way memory regions are registered in the resource tree, but that merely covers up the problem. On ARM64 memory resources registered in yet another way and there the issue of wrong usage of pfn_valid() to ensure availability of the linear map is also covered. Implement arch_memremap_can_ram_remap() on ARM and ARM64 to prevent access to NOMAP regions via the linear mapping in memremap().

Currently, EFAULT is returned when the VMA is not found, instead of -EFAULT. The users of this syscall will therefore believe the syscall succeeded in case the VMA didn't exist, as it returns a pointer to address 0xe (0xe being the value of EFAULT). Fix the sign of the error value.
