Increase the coverage of a test implemented in commit 301a62dfb0d0
("vsock/test: Add test for UAF due to socket unbinding"). Take this
opportunity to factor out some utility code, drop a redundant sync between
client and server, and introduce a /proc/kallsyms harvesting logic for
auto-detecting registered vsock transports.Signed-off-by: Michal Luczaj <m...@rbox.co> --- Changes in v3: - Drop "RFC" prefix, rebase, amend commit logs - get_transports(): don't look for a symbol that was already found - Expand testcase comments, clean up the code [Stefano] - Streamline `enum transport` and `transport_ksyms` [Stefano] - Move KALLSYMS_* defines from utils.h to utils.c [Stefano] - Link to v2: https://lore.kernel.org/r/20250528-vsock-test-inc-cov-v2-0-8f655b40d...@rbox.co Changes in v2: - Speed up: don't bother checking EINTR or respecting timeout on connect()s - Introduce get_transports(), warn on unsupported setup [Stefano] - Comment the code, drop the sync, introduce vsock_bind_try() [Stefano] - Link to v1: https://lore.kernel.org/r/20250523-vsock-test-inc-cov-v1-1-fa3507941...@rbox.co --- Michal Luczaj (3): vsock/test: Introduce vsock_bind_try() helper vsock/test: Introduce get_transports() vsock/test: Cover more CIDs in transport_uaf test tools/testing/vsock/util.c | 80 ++++++++++++++++++++++++++++++++-- tools/testing/vsock/util.h | 30 +++++++++++++ tools/testing/vsock/vsock_test.c | 93 ++++++++++++++++++++++++++++++++-------- 3 files changed, 181 insertions(+), 22 deletions(-) --- base-commit: 0097c4195b1d0ca57d15979626c769c74747b5a0 change-id: 20250326-vsock-test-inc-cov-b823822bdb78 Best regards, -- Michal Luczaj <m...@rbox.co>
