Whatever we do in the loop the skb should not remain on as ctx->recv_pkt afterwards. We can clear that pointer and restart strparser earlier. This adds overhead of extra linking and unlinking to rx_list but that's not large (upcoming change will switch to unlocked skb list operations). Signed-off-by:

tls_sw_advance_skb() always consumes the skb at the end of the loop. To fall here the following must be true: !async && !is_peek && !retain_skb retain_skb => !zc && rxm->full_len > len # but non-full record implies !zc, so above can be simplified as retain_skb => rxm->full_len > len !async && !is_peek && !(rxm->full_len > len) !async && !is_peek && rxm->full_len <= len tls_sw_advance_skb() returns false if len < rxm->full_len which can't be true given conditions above.

We track both if the last record was handled by async crypto and how many records were async. This is not necessary. We implicitly assume once crypto goes async it will stay that way, otherwise we'd reorder records. So just track if we're in async mode, the exact number of records is not necessary. This change also forces us into "async" mode more consistently in case crypto ever decided to interleave async and sync. Signed-off-by:

tls_sw_advance_skb() caters to the async case when skb argument is NULL. In that case it simply unpauses the strparser. These are surprising semantics to a person reading the code, and result in higher LoC, so inline the __strp_unpause and only call tls_sw_advance_skb() when we actually move past an skb.

We pass zc as a pointer to bool a few functions down as an in/out argument. This is error prone since C will happily evalue a pointer as a boolean (IOW forgetting *zc and writing zc leads to loss of developer time..). Wrap the arguments into a structure. Signed-off-by:

We plumb pointer to chunk all the way to the decryption method. It's set to the length of the text when decrypt_skb_update() returns. I think the code is written this way because original TLS implementation passed &chunk to zerocopy_from_iter() and this was carried forward as the code gotten more complex, without any refactoring. The fix for peek() introduced a new variable - to_decrypt which for all practical purposes is what chunk is going to get set to. Spare ourselves the pointer passing, use to_decrypt. Use this opportunity to clean things up a little further. Note that chunk / to_decrypt was mostly needed for the async path, since the sync path would access rxm->full_len (decryption transforms full_len from record size to text size). Use the right source of truth more explicitly. We have three cases: - async - it's TLS 1.2 only, so chunk == to_decrypt, but we need the min() because to_decrypt is a whole record and we don't want to underflow len. Note that we can't handle partial record by falling back to sync as it would introduce reordering against records in flight. - zc - again, TLS 1.2 only for now, so chunk == to_decrypt, we don't do zc if len < to_decrypt, no need to check again. - normal - it already handles chunk > len, we can factor out the assignment to rxm->full_len and share it with zc.

Daniel Borkmann says: ==================== pull-request: bpf-next 2022-04-09 We've added 63 non-merge commits during the last 9 day(s) which contain a total of 68 files changed, 4852 insertions(+), 619 deletions(-). The main changes are: 1) Add libbpf support for USDT (User Statically-Defined Tracing) probes. USDTs are an abstraction built on top of uprobes, critical for tracing and BPF, and widely used in production applications, from Andrii Nakryiko. 2) While Andrii was adding support for x86{-64}-specific logic of parsing USDT argument specification, Ilya followed-up with USDT support for s390 architecture, from Ilya Leoshkevich. 3) Support name-based attaching for uprobe BPF programs in libbpf. The format supported is `u[ret]probe/binary_path:[raw_offset|function[+offset]]`, e.g. attaching to libc malloc can be done in BPF via SEC("uprobe/libc.so.6:malloc") now, from Alan Maguire. 4) Various load/store optimizations for the arm64 JIT to shrink the image size by using arm64 str/ldr immediate instructions. Also enable pointer authentication to verify return address for JITed code, from Xu Kuohai. 5) BPF verifier fixes for write access checks to helper functions, e.g. rd-only memory from bpf_*_cpu_ptr() must not be passed to helpers that write into passed buffers, from Kumar Kartikeya Dwivedi. 6) Fix overly excessive stack map allocation for its base map structure and buckets which slipped-in from cleanups during the rlimit accounting removal back then, from Yuntao Wang. 7) Extend the unstable CT lookup helpers for XDP and tc/BPF to report netfilter connection tracking tuple direction, from Lorenzo Bianconi. 8) Improve bpftool dump to show BPF program/link type names, Milan Landaverde. 9) Minor cleanups all over the place from various others. * https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (63 commits) bpf: Fix excessive memory allocation in stack_map_alloc() selftests/bpf: Fix return value checks in perf_event_stackmap test selftests/bpf: Add CO-RE relos into linked_funcs selftests libbpf: Use weak hidden modifier for USDT BPF-side API functions libbpf: Don't error out on CO-RE relos for overriden weak subprogs samples, bpf: Move routes monitor in xdp_router_ipv4 in a dedicated thread libbpf: Allow WEAK and GLOBAL bindings during BTF fixup libbpf: Use strlcpy() in path resolution fallback logic libbpf: Add s390-specific USDT arg spec parsing logic libbpf: Make BPF-side of USDT support work on big-endian machines libbpf: Minor style improvements in USDT code libbpf: Fix use #ifdef instead of #if to avoid compiler warning libbpf: Potential NULL dereference in usdt_manager_attach_usdt() selftests/bpf: Uprobe tests should verify param/return values libbpf: Improve string parsing for uprobe auto-attach libbpf: Improve library identification for uprobe binary path resolution selftests/bpf: Test for writes to map key from BPF helpers selftests/bpf: Test passing rdonly mem to global func bpf: Reject writes for PTR_TO_MAP_KEY in check_helper_mem_access bpf: Check PTR_TO_MEM | MEM_RDONLY in check_helper_mem_access ... ==================== Link: https://lore.kernel.org/r/20220408231741.19116-1-daniel@iogearbox.netSigned-off-by:

The 'n_buckets * (value_size + sizeof(struct stack_map_bucket))' part of the allocated memory for 'smap' is never used after the memlock accounting was removed, thus get rid of it. [ Note, Daniel: Commit b936ca64 ("bpf: rework memlock-based memory accounting for maps") moved `cost += n_buckets * (value_size + sizeof(struct stack_map_bucket))` up and therefore before the bpf_map_area_alloc() allocation, sigh. In a later step commit c85d6913 ("bpf: move memory size checks to bpf_map_charge_init()"), and the overflow checks of `cost >= U32_MAX - PAGE_SIZE` moved into bpf_map_charge_init(). And then 37086810 ("bpf: Eliminate rlimit-based memory accounting for stackmap maps") finally removed the bpf_map_charge_init(). Anyway, the original code did the allocation same way as /after/ this fix. ] Fixes: b936ca64 ("bpf: rework memlock-based memory accounting for maps") Signed-off-by:

The 8000 series and newer NICs all get hardware timestamps from the MAC and can provide timestamps on a normal TX queue, rather than via a slow path through the MC. As such we can use this path for any packet where a hardware timestamp is requested. This also enables support for PTP over transports other than IPv4+UDP. Signed-off-by:

Use __weak __hidden for bpf_usdt_xxx() APIs instead of much more confusing `static inline __noinline`. This was previously impossible due to libbpf erroring out on CO-RE relocations pointing to eliminated weak subprogs. Now that previous patch fixed this issue, switch back to __weak __hidden as it's a more direct way of specifying the desired behavior. Signed-off-by:

Andrii Nakryiko authored
During BPF static linking, all the ELF relocations and .BTF.ext information (including CO-RE relocations) are preserved for __weak subprograms that were logically overriden by either previous weak subprogram instance or by corresponding "strong" (non-weak) subprogram. This is just how native user-space linkers work, nothing new. But libbpf is over-zealous when processing CO-RE relocation to error out when CO-RE relocation belonging to such eliminated weak subprogram is encountered. Instead of erroring out on this expected situation, log debug-level message and skip the relocation. Fixes: db2b8b06 ("libbpf: Support CO-RE relocations for multi-prog sections") Signed-off-by:

During BTF fix up for global variables, global variable can be global weak and will have STB_WEAK binding in ELF. Support such global variables in addition to non-weak ones. This is not the problem when using BPF static linking, as BPF static linker "fixes up" BTF during generation so that libbpf doesn't have to do it anymore during bpf_object__open(), which led to this not being noticed for a while, along with a pretty rare (currently) use of __weak variables and maps.

Ilya Leoshkevich says: ==================== This series adds USDT support for s390, making the "usdt" test pass there. Patch 1 is a collection of minor cleanups, patch 2 adds BPF-side support, patch 3 adds userspace-side support. ==================== Signed-off-by: -
Ilya Leoshkevich authored
The logic is superficially similar to that of x86, but the small differences (no need for register table and dynamic allocation of register names, no $ sign before constants) make maintaining a common implementation too burdensome. Therefore simply add a s390x-specific version of parse_usdt_arg(). Note that while bcc supports index registers, this patch does not. This should not be a problem in most cases, since s390 uses a default value "nor" for STAP_SDT_ARG_CONSTRAINT. Signed-off-by:

Ido Schimmel says: ==================== net/sched: Better error reporting for offload failures This patchset improves error reporting to user space when offload fails during the flow action setup phase. That is, when failures occur in the actions themselves, even before calling device drivers. Requested / reported in [1]. This is done by passing extack to the offload_act_setup() callback and making use of it in the various actions. Patches #1-#2 change matchall and flower to log error messages to user space in accordance with the verbose flag. Patch #3 passes extack to the offload_act_setup() callback from the various call sites, including matchall and flower. Patches #4-#11 make use of extack in the various actions to report offload failures. Patch #12 adds an error message when the action does not support offload at all. Patches #13-#14 change matchall and flower to stop overwriting more specific error messages.
