Daniel T. Lee	ceff135b9d	samples: bpf: Fix lwt_len_hist reusing previous BPF map ... [ Upstream commit 0afe0a998c40085a6342e1aeb4c510cccba46caf ] Currently, lwt_len_hist's map lwt_len_hist_map is uses pinning, and the map isn't cleared on test end. This leds to reuse of that map for each test, which prevents the results of the test from being accurate. This commit fixes the problem by removing of pinned map from bpffs. Also, this commit add the executable permission to shell script files. Fixes: f74599f7c5 ("bpf: Add tests and samples for LWT-BPF") Signed-off-by: Daniel T.

Magnus Karlsson	7762afa04f	samples/bpf: Fix possible deadlock in xdpsock ... [ Upstream commit 5a2a0dd88f0f267ac5953acd81050ae43a82201f ] Fix a possible deadlock in the l2fwd application in xdpsock that can occur when there is no space in the Tx ring. There are two ways to get the kernel to consume entries in the Tx ring: calling sendto() to make it send packets and freeing entries from the completion ring, as the kernel will not send a packet if there is no space for it to add a completion entry in the completion ring. The Tx loop in l2fwd only used to call sendto(). This patches adds cleaning the completion ring in that loop.

Sherry Sun	821dcabafd	misc: vop: add round_up(x,4) for vring_size to avoid kernel panic ... [ Upstream commit cc1a2679865a94b83804822996eed010a50a7c1d ] Since struct _mic_vring_info and vring are allocated together and follow vring, if the vring_size() is not four bytes aligned, which will cause the start address of struct _mic_vring_info is not four byte aligned. For example, when vring entries is 128, the vring_size() will be 5126 bytes. The _mic_vring_info struct layout in ddr looks like: 0x90002400: 00000000 00390000 EE010000 0000C0FF Here 0x39 is the avail_idx member, and 0xC0FFEE01 is the magic member. When EP use ioread32(magic) to reads the magic in RC's share memory, it will cause kernel panic on ARM64 platform due to the cross-byte io read. Here read magic in user space use le32toh(vr0->info->magic) will meet the same issue. So add round_up(x,4) for vring_size, then the struct _mic_vring_info will store in this way: 0x90002400: 00000000 00000000 00000039 C0FFEE01 Which will avoid kernel panic when read magic in struct _mic_vring_info.

Greg Kroah-Hartman	a35cf72836	ANDROID: GKI: Fix up "do not export symbol_get/put()" commit ... When removing the export from symbol_get/put(), I disabled lots of different drivers in the allmodconfig build file. As some pointed out, that's not the nicest thing to do, as we really do want the build coverage, so instead, "tweak" the Kconfig files to make the problamatic modules be built-in to the kernel image. That removes the problem of the export going away and still gives us good build testing coverage, without modifying any real-world device configurations. Note, 3 config options are "turned off" so they can not be selected, as they could not be worked around in any semi-sane manner: VIDEO_CX23885 DELL_LAPTOP SAMPLE_HW_BREAKPOINT none of which affects any known Android devices.

Jann Horn	f4f235309b	vmalloc: fix remap_vmalloc_range() bounds checks ... commit bdebd6a2831b6fab69eb85cee74a8ba77f1a1cc2 upstream. remap_vmalloc_range() has had various issues with the bounds checks it promises to perform ("This function checks that addr is a valid vmalloc'ed area, and that it is big enough to cover the vma") over time, e.g.: - not detecting pgoff<<PAGE_SHIFT overflow - not detecting (pgoff<<PAGE_SHIFT)+usize overflow - not checking whether addr and addr+(pgoff<<PAGE_SHIFT) are the same vmalloc allocation - comparing a potentially wildly out-of-bounds pointer with the end of the vmalloc region In particular, since commit fc9702273e2e ("bpf: Add mmap() support for BPF_MAP_TYPE_ARRAY"), unprivileged users can cause kernel null pointer dereferences by calling mmap() on a BPF map with a size that is bigger than the distance from the start of the BPF map to the end of the address space. This could theoretically be used as a kernel ASLR bypass, by using whether mmap() with a given offset oopses or returns an error code to perform a binary search over the possible address range. To allow remap_vmalloc_range_partial() to verify that addr and addr+(pgoff<<PAGE_SHIFT) are in the same vmalloc region, pass the offset to remap_vmalloc_range_partial() instead of adding it to the pointer in remap_vmalloc_range(). In remap_vmalloc_range_partial(), fix the check against get_vm_area_size() by using size comparisons instead of pointer comparisons, and add checks for pgoff.

Will Deacon	37e6992fe9	FROMGIT: samples/hw_breakpoint: drop HW_BREAKPOINT_R when reporting writes ... Patch series "Unexport kallsyms_lookup_name() and kallsyms_on_each_symbol()". Despite having just a single modular in-tree user that I could spot, kallsyms_lookup_name() is exported to modules and provides a mechanism for out-of-tree modules to access and invoke arbitrary, non-exported kernel symbols when kallsyms is enabled. This patch series fixes up that one user and unexports the symbol along with kallsyms_on_each_symbol(), since that could also be abused in a similar manner. I would like to avoid out-of-tree modules being easily able to call functions that are not exported. kallsyms_lookup_name() makes this trivial to the point that there is very little incentive to rework these modules to either use upstream interfaces correctly or propose functionality which may be otherwise missing upstream. Both of these latter solutions would be pre-requisites to upstreaming these modules, and the current state of things actively discourages that approach. The background here is that we are aiming for Android devices to be able to use a generic binary kernel image closely following upstream, with any vendor extensions coming in as kernel modules. In this case, we (Google) end up maintaining the binary module ABI within the scope of a single LTS kernel. Monitoring and managing the ABI surface is not feasible if it effectively includes all data and functions via kallsyms_lookup_name(). Of course, we could just carry this patch in the Android kernel tree, but we're aiming to carry as little as possible (ideally nothing) and I think it's a sensible change in its own right. I'm surprised you object to it, in all honesty. Now, you could turn around and say "that's not upstream's problem", but it still seems highly undesirable to me to have an upstream bypass for exported symbols that isn't even used by upstream modules. It's ripe for abuse and encourages people to work outside of the upstream tree. The usual rule is that we don't export symbols without a user in the tree and that seems especially relevant in this case. Joe Lawrence said: : FWIW, kallsyms was historically used by the out-of-tree kpatch support : module to resolve external symbols as well as call set_memory_r{w,o}() : API. All of that support code has been merged upstream, so modern kpatch : modules* no longer leverage kallsyms by default. : : That said, there are still some users who still use the deprecated support : module with newer kernels, but that is not officially supported by the : project. This patch (of 3): Given the name of a kernel symbol, the 'data_breakpoint' test claims to "report any write operations on the kernel symbol". However, it creates the breakpoint using both HW_BREAKPOINT_W and HW_BREAKPOINT_R, which menas it also fires for read access. Drop HW_BREAKPOINT_R from the breakpoint attributes.

This was reported once before[0], but it seems the flag to explicitly turn off the stack protector wasn't added to the Makefile, so do that now.

When sample xdp_redirect_cpu was converted to use libbpf, the tracepoints used by this sample were not getting attached automatically like with bpf_load.c. The BPF-maps was still getting loaded, thus nobody notice that the tracepoints were not updating these maps.

The 'clean' rule in the samples/bpf Makefile tries to remove backup files (ending in ~). However, if no such files exist, it will instead try to remove the user's home directory.

Jesper Dangaard Brouer	634813e41f	samples/bpf: Fix broken xdp_rxq_info due to map order assumptions ... commit edbca120a8cdfa5a5793707e33497aa5185875ca upstream. In the days of using bpf_load.c the order in which the 'maps' sections were defines in BPF side (*_kern.c) file, were used by userspace side to identify the map via using the map order as an index. In effect the order-index is created based on the order the maps sections are stored in the ELF-object file, by the LLVM compiler. This have also carried over in libbpf via API bpf_map__next(NULL, obj) to extract maps in the order libbpf parsed the ELF-object file. When BTF based maps were introduced a new section type ".maps" were created. I found that the LLVM compiler doesn't create the ".maps" sections in the order they are defined in the C-file. The order in the ELF file is based on the order the map pointer is referenced in the code. This combination of changes lead to xdp_rxq_info mixing up the map file-descriptors in userspace, resulting in very broken behaviour, but without warning the user. This patch fix issue by instead using bpf_object__find_map_by_name() to find maps via their names. (Note, this is the ELF name, which can be longer than the name the kernel retains).

Daniel T. Lee	76aff568ee	samples: bpf: update map definition to new syntax BTF-defined map ... commit 451d1dc886b548d6e18c933adca326c1307023c9 upstream. Since, the new syntax of BTF-defined map has been introduced, the syntax for using maps under samples directory are mixed up. For example, some are already using the new syntax, and some are using existing syntax by calling them as 'legacy'. As stated at commit abd29c9314 ("libbpf: allow specifying map definitions using BTF"), the BTF-defined map has more compatablility with extending supported map definition features. The commit doesn't replace all of the map to new BTF-defined map, because some of the samples still use bpf_load instead of libbpf, which can't properly create BTF-defined map. This will only updates the samples which uses libbpf API for loading bpf program. (ex. bpf_prog_load_xattr) Signed-off-by: Daniel T.

[ Upstream commit bba1b2a890253528c45aa66cf856f289a215bfbc ] Previously, when this sample is added, commit 1c47910ef8 ("samples/bpf: add perf_event+bpf example"), a symbol 'sys_read' and 'sys_write' has been used without no prefixes. But currently there are no exact symbols with these under kallsyms and this leads to failure.

Sven Schnelle	7aa117bfc2	samples/trace_printk: Wait for IRQ work to finish ... commit 01f36a554e3ef32f9fc4b81a4437cf08fd0e4742 upstream. trace_printk schedules work via irq_work_queue(), but doesn't wait until it was processed. The kprobe_module.tc testcase does: :;: "Load module again, which means the event1 should be recorded";: modprobe trace-printk grep "event1:" trace so the grep which checks the trace file might run before the irq work was processed. Fix this by adding a irq_work_sync().

Sargun Dhillon	de7cd9dfc5	samples/seccomp: Zero out members based on seccomp_notif_sizes ... commit 771b894f2f3dfedc2ba5561731fffa0e39b1bbb6 upstream. The sizes by which seccomp_notif and seccomp_notif_resp are allocated are based on the SECCOMP_GET_NOTIF_SIZES ioctl. This allows for graceful extension of these datastructures. If userspace zeroes out the datastructure based on its version, and it is lagging behind the kernel's version, it will end up sending trailing garbage. On the other hand, if it is ahead of the kernel version, it will write extra zero space, and potentially cause corruption.

[ Upstream commit 3cad8f911575191fb3b81d8ed0e061e30f922223 ] Currently, proc_cmd is used to dispatch command to 'pg_ctrl', 'pg_thread', 'pg_set'. proc_cmd is designed to check command result with grep the "Result:", but this might fail since this string is only shown in 'pg_thread' and 'pg_set'. This commit fixes this logic by grep-ing the "Result:" string only when the command is not for 'pg_ctrl'. For clarity of an execution flow, 'errexit' flag has been set.

Support for i40e, ixgbe and mlx5e, from Kevin and Maxim. 2) Addition of a wakeup flag for AF_XDP tx and fill rings so the application can wake up the kernel for rx/tx processing which avoids busy-spinning of the latter, useful when app and driver is located on the same core. Support for i40e, ixgbe and mlx5e, from Magnus and Maxim. 3) bpftool fixes for printf()-like functions so compiler can actually enforce checks, bpftool build system improvements for custom output directories, and addition of 'bpftool map freeze' command, from Quentin. 4) Support attaching/detaching XDP programs from 'bpftool net' command, from Daniel. 5) Automatic xskmap cleanup when AF_XDP socket is released, and several barrier/{read,write}_once fixes in AF_XDP code, from Björn. 6) Relicense of bpf_helpers.h/bpf_endian.h for future libbpf inclusion as well as libbpf versioning improvements, from Andrii. 7) Several new BPF kselftests for verifier precision tracking, from Alexei. 8) Several BPF kselftest fixes wrt endianess to run on s390x, from Ilya. 9) And more BPF kselftest improvements all over the place, from Stanislav. 10) Add simple BPF map op cache for nfp driver to batch dumps, from Jakub. 11) AF_XDP socket umem mapping improvements for 32bit archs, from Ivan. 12) Add BPF-to-BPF call and BTF line info support for s390x JIT, from Yauheni. 13) Small optimization in arm64 JIT to spare 1 insns for BPF_MOD, from Jerin. 14) Fix an error check in bpf_tcp_gen_syncookie() helper, from Petar. 15) Various minor fixes and cleanups, from Nathan, Masahiro, Masanari, Peter, Wei, Yue. ==================== Signed-off-by: David S.

Kevin Laatz	03895e63ff	samples/bpf: add buffer recycling for unaligned chunks to xdpsock ... This patch adds buffer recycling support for unaligned buffers. Since we don't mask the addr to 2k at umem_reg in unaligned mode, we need to make sure we give back the correct (original) addr to the fill queue. We achieve this using the new descriptor format and associated masks. The new format uses the upper 16-bits for the offset and the lower 48-bits for the addr. Since we have a field for the offset, we no longer need to modify the actual address. As such, all we have to do to get back the original address is mask for the lower 48 bits (i.e. strip the offset and we get the address on it's own).
