Tamir Duberstein	71bc3ea0b5	integration-test: avoid reliance on kernel headers ... This should allow us to build on any system.	1 year ago
Tamir Duberstein	b46fb616be	integration-test: fix BTF relocation test ... The struct_flavors test previously expected the same thing with and without relocations. It now expects different values. Also rename an enum variant "u64" to "S64". This was a typo. Turns out that U32 is a type that exists in kernel headers, so all enum values are suffixed with "_VAL". Remove stdlib.h and the call to exit(). This alone makes the test fail with a poisoned relocation. Bringing over the map definition makes the test work again.	1 year ago

Tamir Duberstein	2a054d76ae	btf: avoid multiple vector allocations ... Rather than creating an empty vector and iteratively appending - which might induce intermediate allocations - create an ExactSizeIterator and collect it into a vector, which should produce exactly one allocation.	1 year ago
Dave Tucker	1979da92a7	Merge pull request #721 from dave-tucker/fix-funcinfo ... aya: Fix (func|line)_info multiple progs in section	1 year ago
Dave Tucker	79ea64ca7f	aya: Fix (func|line)_info multiple progs in section ... This commit fixes the (func|line)_info when we have multiple programs in the same section. The integration test reloc.bpf.c serves as our test case here. This required filtering down the (func|line)_info to only that in scope of the current symbol + then adjusting the offets to appease the kernel.

Andrew Werner	79c9489a4f	integration-test: attach uprobes to self ... For unclear reasons, two of the integration tests related to uprobes were resolving a symbol in libc. The integration-test binary can be built statically, in which case it would not load or reference libc. Statically linking the integration tests and running them in a VM without a userland is a convenient mechanism to exercise the tests against different kernel versions. The fact that the statically linked integration-test binary does not load libc is not the only reason these tests failed in such an environment. In fact, the logic to look in the process's memory maps was not running (because no pid was being passed). Separate logic to determine which object file to use when attempting to resolve a symbol for attaching a uprobe changes its behavior based on whether that target is an absolute path. If the target is not an absolute path, the code searches through the LdSoCache. This cache does not always exist in linux systems; when an attach call is made with a relative path target and there is no /etc/ld.so.cache file, the attach call will fail. This commit does not change that behavior, it merely sidesteps it.	1 year ago
Andrew Werner	dcc6b84a88	programs/uprobe: extract library path resolving ... The function is extracted so that a test could be written. This test is valid on linux-gnu targets, and it doesn't need any special privileges. This is in anticipation of removing the code that uses this functionality (seemingly incidentally) from integration tests.	1 year ago

Dave Tucker	7eebdcbdeb	aya-bpf-macros: Cleanup and remove required_args ... This commit cleans up the recently refactored aya-bpf-macros to be a little easier to maintain: Cosmetic changes: 1. The flow of the parse function is the same in each file 2. Useless if !attrs.is_empty() guards were removed 3. The compile error when cgroup_sock programs have an invalid attach_type was in the wrong location Functional changes: 1. Remove pop_required_arg. All args are optional and making them required was a mistake on my part. We may revisit this later. 2. Rename pop_arg to pop_string_arg 3. Implement pop_bool_arg to allow for single idents to be mixed with our key/value pair syntax in macro attributes. This is used for `sleepable` and `frags` in XDP programs.

Tamir Duberstein	dca5e6c167	integration-test: Remove runtime toolchain deps ... Move the use of clang and llvm-objcopy from run-time to build-time. This allows the integration tests to run on VMs with simpler userlands. Create a new CI job to build the integration tests separately from running them. Ship them from that job to the runner job using github actions artifacts.	1 year ago
