Define __mig_strlen to support dynamically sized strings in hurd RPCs

2023-05-01T00:24:04Z

We make lib{mach,hurd}user.so only call __mig_strlen which can be relocated before libc.so is relocated, similar to what is done with __mig_memcpy. Message-Id:

hurd: break relocation loop between libc.so and lib{mach,hurd}user.so

2020-11-13T23:52:52Z

See https://sourceware.org/pipermail/libc-alpha/2020-November/119575.html lib{mach,hurd}user.so gets relocated before libc.so, but its references to strpcpy and memcpy would need an ifunc decision, which e.g. on x86 relies on cpu_features, but libc.so's _rtld_global_ro is not relocated yet. We can however just make lib{mach,hurd}user.so only call non-ifunc functions, which can be relocated before libc.so is relocated.

hurd: Fix htl link failure

2018-06-14T15:09:18Z

126b3ec370f0 ("hurd: Avoid PLTs for __mach_thread_self and __mach_reply_port") made mach traps hidden, but htl actually uses two of them. Re-expose them for now. Exposing them properly will be more involved since their definition is generated. * sysdeps/mach/include/mach/mach_traps.h (__mach_thread_self, __mach_task_self): Remove attribute_hidden.

This reverts commit d4379e0216d01fd1395b1f3b37255e3486760135: the proper headers are actually already getting installed.
