Additionally, given that IFLA_IFNAME also expects a null-terminated string, callers of rtaddr_add_str{,sz}() could simply use the rtaddr_add_strsz() variant. (which has been renamed to remove the trailing `sz`) memset() has been used for this function since it is unchecked and thus circumvents the issue discussed in the previous paragraph.

The `header` variable is a `const char *` pointer. `sizeof()` on a pointer returns the size of the pointer itself, not the length of the string literal it points to. This makes the code's behavior dependent on the architecture's pointer size. This bug was identified on a 32-bit ARM build (`gsi_tv_arm`) for Android, running on an ARMv8-based device, compiled with Clang 19.0.1. On this 32-bit architecture, `sizeof(char *)` is 4. The expression `sizeof(header) - 1` resulted in an incorrect offset of 3, causing the test to read the wrong character from `/proc/[tid]/status` and fail. On 64-bit architectures, `sizeof(char *)` is 8, so the expression coincidentally evaluates to 7, which matches the length of "State:\t". This is why the bug likely remained hidden on 64-bit builds. To fix this and make the code portable and correct across all architectures, this patch replaces `sizeof(header) - 1` with `strlen(header)`. The `strlen()` function correctly calculates the string's length, ensuring the correct offset is always used.

The test creates ublk devices with fault_inject target and very large delay (60s) to simulate blocked partition table reads, then kills the daemon to verify proper state transitions without hanging: 1. Without recovery support: - Create device with fault_inject and 60s delay - Kill daemon while partition scan may be blocked - Verify device transitions to DEAD state 2. With recovery support (-r 1): - Create device with fault_inject, 60s delay, and recovery - Kill daemon while partition scan may be blocked - Verify device transitions to QUIESCED state Before the async partition scan fix, killing the daemon during partition scan would cause deadlock as partition scan held ub->mutex while waiting for IO. With the async fix, partition scan happens in a work function and flush_work() ensures proper synchronization. Add _add_ublk_dev_no_settle() helper function to skip udevadm settle, which would otherwise hang waiting for partition scan events to complete when partition table read is delayed.

The root cause is that an empty fixture struct results in `sizeof(self_private)` evaluating to 0. The compiler's fortification checks then detect the `memset()` call with a compile-time constant size of 0, issuing a `-Wuser-defined-warnings` which is promoted to an error by `-Werror`. An initial attempt to guard the call with `if (sizeof(self_private) > 0)` was insufficient. The compiler's static analysis is aggressive enough to flag the `memset(..., 0)` pattern before evaluating the conditional, thus still triggering the error. To resolve this robustly, this change introduces a `static inline` helper function, `__kselftest_memset_safe()`. This function wraps the size check and the `memset()` call. By replacing the direct `memset()` in the `__TEST_F_IMPL` macro with a call to this helper, we create an abstraction boundary. This prevents the compiler's static analyzer from "seeing" the problematic pattern at the macro expansion site, resolving the build failure.
