elf: Fix runtime linker auditing on aarch64 (BZ #26643)
|
|
|
abe59f |
|
|
|
abe59f |
The rtld audit support show two problems on aarch64:
|
|
|
abe59f |
|
|
|
abe59f |
1. _dl_runtime_resolve does not preserve x8, the indirect result
|
|
|
abe59f |
location register, which might generate wrong result calls
|
|
|
abe59f |
depending of the function signature.
|
|
|
abe59f |
|
|
|
abe59f |
2. The NEON Q registers pushed onto the stack by _dl_runtime_resolve
|
|
|
abe59f |
were twice the size of D registers extracted from the stack frame by
|
|
|
abe59f |
_dl_runtime_profile.
|
|
|
abe59f |
|
|
|
abe59f |
While 2. might result in wrong information passed on the PLT tracing,
|
|
|
abe59f |
1. generates wrong runtime behaviour.
|
|
|
abe59f |
|
|
|
abe59f |
The aarch64 rtld audit support is changed to:
|
|
|
abe59f |
|
|
|
abe59f |
* Both La_aarch64_regs and La_aarch64_retval are expanded to include
|
|
|
abe59f |
both x8 and the full sized NEON V registers, as defined by the
|
|
|
abe59f |
ABI.
|
|
|
abe59f |
|
|
|
abe59f |
* dl_runtime_profile needed to extract registers saved by
|
|
|
abe59f |
_dl_runtime_resolve and put them into the new correctly sized
|
|
|
abe59f |
La_aarch64_regs structure.
|
|
|
abe59f |
|
|
|
abe59f |
* The LAV_CURRENT check is change to only accept new audit modules
|
|
|
abe59f |
to avoid the undefined behavior of not save/restore x8.
|
|
|
abe59f |
|
|
|
abe59f |
* Different than other architectures, audit modules older than
|
|
|
abe59f |
LAV_CURRENT are rejected (both La_aarch64_regs and La_aarch64_retval
|
|
|
abe59f |
changed their layout and there are no requirements to support multiple
|
|
|
abe59f |
audit interface with the inherent aarch64 issues).
|
|
|
abe59f |
|
|
|
abe59f |
* A new field is also reserved on both La_aarch64_regs and
|
|
|
abe59f |
La_aarch64_retval to support variant pcs symbols.
|
|
|
abe59f |
|
|
|
abe59f |
Similar to x86, a new La_aarch64_vector type to represent the NEON
|
|
|
abe59f |
register is added on the La_aarch64_regs (so each type can be accessed
|
|
|
abe59f |
directly).
|
|
|
abe59f |
|
|
|
abe59f |
Since LAV_CURRENT was already bumped to support bind-now, there is
|
|
|
abe59f |
no need to increase it again.
|
|
|
abe59f |
|
|
|
abe59f |
Checked on aarch64-linux-gnu.
